A stem is mounted inside the hollow rod so as to be free to move axially and to rotate around its own axis when extended all the way out of said body, the front end of the stem being pointed and supporting a detachable tapered head having a surface facing the body with staple bending depressions spaced around the periphery of the head.

PATENTED JUL 20 |97| SHEET 1 BF 2 PATENTED JUL20 IHYI SHEET 2 [IF 2 SURGICAL INSTRUMENT FOR SUTURTNG HOLLOW ORGANS IN INFANTS Known in the present day surgical practice are surgical in- 0 struments for placing circular anastomoses between hollow organs (cf. USSR Authors Certificates Nos. 195,041 and 141,589; patents: Great Britain No. 942,122, US. No. 3,193,165, Canada No. 736,256, Switzerland No. 407,407, France No. 1,349,201 and No. 1,461,464, Italy No. 674,174 and 724,978, Japan No. 456,544, Belgium No. 668,917). Said instruments feature a tubular body carrying a staple portion said tubular body housing a central stem and a movable hollow rod with a cylindrical knife and a staple ejector, a detachable supporting head with depressions for bending the staple ends and a circular recess at whose bottom a replaceable plastic washer is located.

Located inside said supporting head, in the course of the instrument operation, are: a stem connecting the supporting head to the staple portion, the cylindrical knife and the tissues being sutured which are fixed between the end faces of the staple and supporting portions of the instrument.

The aforementioned known instruments are impracticable for suturing the esophagus in newborn infants in the case of atresia thereof, this being due to anatomical peculiarities inherent in newborn infants, mostly on account of the small size of their organs, as well as due to the fineness and delicacy of the tissues thereof.

An instrument designed for suturing the esophagus in newborn infants should have the diameter of its working portions (i.e., the tubular staple portion and the supporting head) not exceeding 6 or 7 mm., since for placing anastomotic sutures, said portions are to be introduced into the inner cavity of those sectors of the esophagus which are to be sutured.

It is evident that the inner space of the supporting head of such a diameter is not sufficient to accommodate all the necessary components for obtaining a high-quality suture and for making an incision to obtain an anastomotic aperture through which the sutured portions are free to intercornmunicate. I

Appertaining to the aforementioned components are: the depressions for bending the staples, said depressions being provided on the end face surface of the abovesaid supporting head; the cylindrical knife capable of cutting an aperture for a free communicating between the sutured portions of the esophagus; the stem connecting the supporting head of the instrument to the staple portion thereof; the circular recess at the bottom of which the replaceable plastic washer is provided, said recess serving to accommodate the esophageal ends being sutured and to excise the surplus tissue to restore a free permeability of the organ involved.

Moreover, to provide a reliable excision of the anastomotic aperture and a minimum traumatic lesion inflicted upon the living tissues, at slitlike gap or clearance should be provided between the inner surface of said circular recess and the outer surface of the cylindrical knife, said gap or clearance being in excess of twice the maximum thickness of the esophageal walls being sutured.

A free spaces should be left between the inner surface of the knife and the stern for the lower end ofthe esophagus constricted with a purse string or circumflexional suture to freely sink thereinto.

Apparently, it is by reason of the difficulties mentioned above that despite the great progress in mechanization of the process of placing sutures during surgical operations and the wide variety of special suturing instruments available, there has not been previously suggested any instrument which is capable of placing anastomoses between the esophagus sections in the case ofits atresia occurring in newborn infants.

it is therefore a primary object of the present invention to develop a small-size surgical instrument for suturing the es ophagus in newborn infants in the case ofits atresia.

It is a specific object of the present invention to provide such a surgical instrument that is capable of quickly and reliably placing a circumferential anastornotic suture, as well as to provide a guaranteed excision of the surplus tissue to restore the lumen of the sutured esophagus with a minimum traumatic lesion inflicted upon the tissues thereof during the process of placing an anastomosis.

To accomplish the objects mentioned above, rovision is made in the body of the instrument of the invention for an elastic or springy member capable of insuring a constant rate of travel of the staple ejector at various rates of travel of the rod carrying a puncher, whereas the central stem is free to move reciprocally along the body and to rotate around its own axis when extended all the way out of the body.

With a view to attaining a simple and reliable operation of the instrument, said elastic member is made as a split washer loosely set over the rear portion of the puncher and located inside the instrument body between the end of the rod and the end face of the staple ejector which is likewise set freely on the rear portion of said puncher.

For the purpose of saving space, the cutting device has a puncher associated with the rod and is adapted to interact, during the operation, with the edge of acylindrical depression or recess provided at the face end of the supporting head which receives the puncher.

According to the invention said puncher is provided with a cylindrical projection for the tissues being sutured which is inserted into said cylindrical depression orrecess in the supporting head.

ln accordance with the present invention, for the purpose of convenience, the central stem has a cylindrical tailpiece with a knurled or milled surface, whereas the supporting head has flat regions for a reliable holding of said head by a clamping tool.

An embodiment of the present invention is described hereinbelow by way of example with reference to the appended drawings, wherein:

FlGS. l and 2 are, respectively, a side elevation and a plan view of the surgical instrument for suturing hollow organs in infants;

FIG. 3 is a longitudinal section of an operative end portion of the instrument shown in FIGS. 1 and 2;

FIGv 4 is a section taken on line A-A of FIG. 3;

FIG. 5 is a section taken on line B-B of FlG. l; and

FIG. 6 is a sectional view showing the operation of the instrumcnt according to the invention,

Referring to FIGS. 1 and 2, the instrument of the invention comprises an oblong tubular body 1, a movable handle 2 articulated with the body at the rear portion thereof and a stationary handle 3 rigidly coupled to the body 1.

Located inside the front portion of the body 1 is a splined bushing 4 fixed in position so as to form staple slots 5 (FIGS. 3,4) in combination with the inner surface of the body 1.

A tubular rod 6 passes inside tubular body 1, said rod carrying at its front end a puncher 7 threaded thereto. The puncher 7 has a rear portion or tailpiece 8 on which is loosely supported a cylindrical-shaped staple ejector 9 and a split spring washer 10. The washer l0 affords the possibility for the puncher 7 to move with respect to the staple ejector 9 over a 1 length corresponding to the range of the suturing gap spacing or, in other words, the provision of the spring washer makes it possible, with the travel of the staple ejector 9 being invariable, for the travel of the rod 6 along with the puncher 7 to vary within a required range.

The front end of the puncher 7 is fashioned as a cylindrical portion 11 which extends beyond the body 1 (FIGS. 1,3).

The rod 6 is movable lengthwise of the instrument body 1 by means of a linkage coupled to the movable handle 2 and in cluding an actuating arm 12 of fork-shape passing through an opening 13 in body 1 so as to straddle the rod 6 on lateral surfaces 14 thereof(FlG. l).

In order to secure the movable handle againstmovement, a swivel safety lock (FIGS. 1,2) is provided.

Spaced around the periphery of the cylindrical staple ejector 9 are toothlike pins 16 adapted to fit onto the staple slots 5 to drive staples therefrom under the action of the rod 6 (FIG. 3).

Extending inside the tubular rod 6 and the puncher 7 is a stem 17 whose front pointed end 18 is screwed into a supporting head 19. A knob 20 on the rear of stem 17 is cylindrical and its outer surface is knurled to facilitate manipulation thereof(FIGS. land z).

The supporting head 19 is made up of two portions, namely, ta ered portion 21 and portion 22, so interconnected that the tapered portion can rotate independently around its axis, while the portion 22 remains stationary (FIG. 3). This is achieved by the construction shown in FIG. 3 wherein the tapered portion 21 is loosely mounted on a cylindrical projection 60 of portion 22, said portion 60 having a circular groove 42 disposed, therein and loosely accommodating end portions 41 of two screws 40 screwed into the tapered portion 21.

At the rear of the supporting head 19 is a cylindrical recess 23 for receiving the lower end of the esophagus to be sutured by forcible insertion by the cylindrical projection 11 on the puncher 7 (FIGS. 3 and 6).

Spaced around the periphery of the rear portion of the supporting head 19 are staple bending depressions 24. In order to insure that the supporting head is set in definite position with respect to the stem 17, provision is engaged in a longitudinal groove 26 (FIG. 3) made on projection 60 of portion 22 for a fixed guide key which engages in a longitudinal groove 26, (FIG. 3) at the end 18 of the stem 17. When the pointed end 18 of the stem 17 is introduced into the supporting head 19, the guide key 25 enters the groove 26 provided on the stem 17, thus preventing the cylindrical portion 22 from rotating about the stem 17 and ensuring a strictly definite position of the portion 22 relative to the stern in the circular direction. The stem 17 is then further advanced into the head 19 by rotating stem 17 while holding portion 19 againstrotation as will be explained more fully later.

The tapered portion 21 of the head is provided with two flat regions 27 for the engagement of the supporting head l9 by a clamping tool (FIGS. 1,2).

In order to insure that the staple slots 5 in the body 1 are in strict alignment with the staple bending depressions 24 in the rear end of the supporting head 19, the stem 17 occupies an angular fixed position with respect to the instrument body 1. This is attained by the provision of a washer 28 having a profiled opening whose shape corresponds to that of the crosssectional area of the stem 17, and by the presence of projections 30 adapted to fit into corresponding slots in the body 1 (FIG. 5).

The washer 28 is fixed to the body 1 by means of a nut 31 (FIGS. 1,2,5).

The stem 17 is provided with two transverse slots 32, 33 and an annular recess 34 (FIG. 1).

When the slot 32 receives a swivel retainer a required suturing gap is obtained between the rear end of of head 19 and the front end of body 1 (FIG. 1).

The slot 32 is inclined relative to the axis of the stem 17 so that the lower portion of the retainer 35, while sliding over the walls of the slot 32. causes the supporting head 19 either to approach the front end of the body 1 or to move away from it within the spacing range of the suturing gap.

The slot 33 Serves for locking the stem 17 by the retainer 35 in such a position that pointed end 18 is completely retracted inside the body 1.

The recess 34 makes it possible for the stem 17 to rotate about its own axis when the recess 34 is aligned with the profiled opening 29 in the washer 28, viz. With the pointed end 18 ofthe stem 17 extended all the way out of the body 1.

INSTRUMENT APPLICATION TECHNIQUE Prior to making use of the instrument it should be loaded with staples and sterilized.

This done, the instrument is prepared for operation, for which purpose the movable handle 2 is locked by the safety lock 15, the supporting head His unscrewed from the instrument and the pointed end 18 of the stem 17 is retracted into the body 1, whereupon the stem is fixed in that position by the engagement of the retainer 35 in slot 33.

Then, the body! of the'instrument is introduced perorally into the upper blind section of the paticnt's esophagus.

When cylindrical projection 11 extending from the body 1 reaches the bottom of the upper blind section of the esophagus, the stem 17 is released by withdrawing the retainer 35 from slot 33 and the stem is moved all the way forward by manual manipulation of knob 20. As a consequence, the pointed end 18 of the stem 17 pierces the bottom of the esophagus penetrates into the operational wound, the cylindrical projection 11 penetrating the into the wound through the resulting hole together with the stem 17.

By the use of any suitable clamping tool, the tapered portion 21 of the supporting head 19 is held by its flat regions 27 provided for the purpose, and the head 19 is introduced into the operational wound to fit over the pointed end 18 of the stem 17 so that the guide key 25 of the portion 22 of said head engages in the groove 26 in the stem 17. Thereupon the stem is rotated by tuming knob 20 until it is screwed home into the tapered portion 21 of the supporting head 19. When assuming that position, the stem 17 is free to rotate, since the recess 34 provided therein is located in the profiled opening 29 in the washer 28.

Having been made fast on the stem 17, the head 19 is introduced into the lumen of the lower section of the esophagus. This done, a purse string or circumflexional suture is drawn tightly around the stem 17 and tied thereon, said suture being preliminarily placed on the edge of the lower section of the esophagus.

Then, the head 19 together with the lower end of the esophagus fixed thereto is brought by the knob 20 of the stem 17 closer to the instrument body 1. When so doing, the lower end of the esophagus drawn tight with a purse string or circumflexional suture rests with its edge against the projection 11 of the puncher 7 extending out of the upper blind section of the esophagus and is thus caused to insert into the recess 23 in the supporting head 19, whereby both the upper blind section and the lower section of the esophagus can be juxtaposed correctly and tightly. Then the stem 17 together with the supporting head 19 is fixed in that position by the engagement of the end of retainer 35 into the transverse slot 32.

Then, the movable handle 2 is released by turning the safety lock 15 and is pressed towards handle 3, whereby suturing is attained.

At the moment the handles 2 and 3 are brought together, a circular staple suture is driven into place by pins 116 and an excision of the tissues is performed (in a manner to be explained later) to provide for a free communication between the upper blind section and the lower sections of the esophagus that have been sutured (FIG. 6).

The formation of an anastomotic aperture in the sutured sections of the esophagus is effected by the puncher 7 which engages the sharp edge 37 of the portion 22 of the supporting head 19 by its bevelled edge 36 to punch out a round aperture.

Upon the formation of an anastomosis, the movable handle 2 is returned to its initial position and is fixed therein with the safety lock 15.

Then, the stem 17 is released by removing the retainer 35 and is moved forward, thus causing the supporting head 19 to move away from the body. Next, the body 1 of the instrument is likewise moved slightly forward. Owing to the tapered shape of the working end 36 of the body 1 it is free to pass inside the sutured sections of the esophagus and through the anastomotic suture thus obtained.

Once the working end of the instrument body as passed beyond the anastomotic suture, the supporting head is brought closer to the body by the displacement of stem 17,,whereupon the entire instrument is extracted from the esophagus.
