DETAILED DES RIPTION OF THE INVENTION
Figs. 2-5 illustrate a particularly advantageous embodime~lt 20~ O
of the surgical rod pusher instrument 601 of the present invention. Figs. 6-9 illustrate the use of this instrument 601 in conjunction with a rod 801, and illustrate the ~pplication of force to the rod 801 in various directions as represented by the arrows. It is noted that this instrument is particularly suitable for use as a spinal instrument, in particular for use with spinal implant6 which utilize a spinal rod (such as 801) for manipulating the rod during spinal surgery. The spinal rod 801 may be utilized in conjunction with the spinal implant system described in co-pending patent application serial number _, filed _ to Cozad et al. which is incorporated herein by reference. However, it is noted that the features of this surgical rod pusher instrument may be utilized with any suitable rod memher, and is not limited to this particular spinal implant system, nor is it limited solely to spinal applications. Thus, this instrument could be utili~ed in conjunction with any suitable surgical rod or elongaled member.
The instrument 601 includes a distal tip 605 or working end portion and an elongated handle 620 extending therefrom. The handle, as shown, may suitably include a gripping portion 622 which blends into a narrower portion 624 which attaches to the distal tip 605. The handle may also include an enlarged proximal portion 623.
The tip 605 includes a rod receiving opening 610 leading into enlarged cavity 612. The cavity includes a plurali~y of rod locator reces~es 614, 615, and 616. The embodiment shown includes three distinct rod locator recesses, first, second, and third recesses 61~, 615, and 616, respectively. Al~o, in the embodiment shown, the enlarged cavity 612 and the rod receiving f .
2~ 0 opening 610 form a substantially cloverleaf-shaped opening, as shown in Fig. 5. Alternatively, the enlarged cavity 612 could be 6ubstantially triangular in shape (not shown) with each angle of the triangle forming a respective rod locator recess and with the rod receiving opening 610 which leads into the cavity 512 being located along one leg of the triangle. In addition, it is noted that embodiments utilizing two, four or more distinct recesse6 (not shown) could also be utilized in keeping with ~he present invention. Each recess 6l4, 615, and 616 has a different directional orientation.
The rod locator recesses 614, 615, and 616 each preferably have a shape which corresponds to the mating portion of the rod 801 which will be in contact or engagement with the selected recess. In the embodiment shown, the rod 801 is cylindrical and the corresponding rod locator recesses 614, 615, and 616 are each substantially semi cylindrical and sized to accept the rod 801 as shown in Figs. 6-9. The recesses could be formed as a suitable portion or segment of a curve as long as the recess~s are adapted to receive the corresponding rod or elongated member 801. A semi-circular recess is preerred over a smaller segmen~
of a curve to help ensure secure location of the rod in the selected recess, and to lessen the likelihood of the rod slipping out of the recess when a force is applied to the instrument 601 against rod 801. Any suitable shapes for the recesses 614, 615, and 616 and for the corresponding mating rod 801 could be utilized. Also, the instrument 601 could utilize recesse6 having different sizes (not shown) if it was desirable to utilize the instrument with varying sized rods 801.
The width "w" of the rod receiving opening 610 is suitably 20~ 9~0 sized to allow the rod 801 having diameter "d" to pass through the opening 610 and into cavity 612.
The first locator recess 614 is located adjacent the second recess 615. Recess 615 is also adjacent the third recess 616.
An extended portion 630 is formed in the instrument 601 between the first and second recesses 614, 615 and between the second and third reees6es 615, 616, as shown in Fig. 5. These extended portions 630 extend from the instrument 601 in toward cavity 61Z, and assi6t in prev~nting the rod 801 from slipping from one recess to an adjacent recess.
The first recess 614 is adapted for application of a first generally sideways or lateral force to the rod 801 when the rod is located therein, as shown in Fig. 7. (The direction of force being applied is shown by arrow.) The second recess 615 is adapted for application of a generally downward force on the rod 801 when the rod is located therein, as shown in Fig. 6. (The direction of fsrce being applied is shown by arrow.) The third recess 616 is adapted for application of a second generally sideway6 or lateral force to the rod 801 (as shown in ~ig. 8) that is substantially opposite in direction to the firs~
sideways force. It is noted that although the arrows in Figs.
6, 7, and 8 indicate a force that is straight down vertically (Fig. 6) or directly horizontal or sideway6 (Figs. 7 and a)~ it is understood that the force could also be applied at any suitable angle, yet toward the general direction shown. The instrument can also be sliqhtly tilted with respect to the horizontal plane, as shown in Fig. 9, which illustrates a slight upwards force being applied to the rod 801. With a small change in manual orientation of the handle 620, instrument 601 can 201~ 0 selectively apply force against a rod in all 360 about the rod ~01.
As s~own in Fig. ~3, the handle 620 may angle in relation to the distal tip 605 at an angle of about 150. This providas for better visualization of the surgical site by the user of Lhe instrument 601. The tip 605 may include a tip extension 608 interconnecting the tip 605 to the handle 620. Thus. ~he angle between the tip extension 608 and handle 620, as shown, is about 150.
In utilizing the instrument 601, the user passes the rod 801 through the rod receiving opening 610 into the enlarged cavity 612. The user then selects one of the plurality of rod locator reces6es 614, 615, and 616 and locates the rod 801 therein. Force is then applied against the rod in the appropriate desired direction.
It is noted that any suitable materials may be utilized for instrument 601. One such material ;s stainless steel.
Regarding manufacturing methods, any suitable methods may be utilized.
While this invention has been described and exemplified in terms of a particularly advantageous embodiment, those skilled in the art can appreciate that modifications can be made without departing from the spirit and scope of this invention.
The rod locator recesses 614, 615, and 616 each preferably have a shape which corresponds to the mating portion of the rod 801 which will be in contact or engagement with the selected recess. In the embodiment shown, the rod 801 is cylindrical and the corresponding rod locator recesses 614, 615, and 616 are each substantially semi cylindrical and sized to accept the rod 801 as shown in Figs. 6-9. The recesses could be formed as a suitable portion or segment of a curve as long as the recess~s are adapted to receive the corresponding rod or elongated member 801. A semi-circular recess is preerred over a smaller segmen~
of a curve to help ensure secure location of the rod in the selected recess, and to lessen the likelihood of the rod slipping out of the recess when a force is applied to the instrument 601 against rod 801. Any suitable shapes for the recesses 614, 615, and 616 and for the corresponding mating rod 801 could be utilized. Also, the instrument 601 could utilize recesse6 having different sizes (not shown) if it was desirable to utilize the instrument with varying sized rods 801.
The width "w" of the rod receiving opening 610 is suitably 20~ 9~0 sized to allow the rod 801 having diameter "d" to pass through the opening 610 and into cavity 612.
The first locator recess 614 is located adjacent the second recess 615. Recess 615 is also adjacent the third recess 616.
An extended portion 630 is formed in the instrument 601 between the first and second recesses 614, 615 and between the second and third reees6es 615, 616, as shown in Fig. 5. These extended portions 630 extend from the instrument 601 in toward cavity 61Z, and assi6t in prev~nting the rod 801 from slipping from one recess to an adjacent recess.
The first recess 614 is adapted for application of a first generally sideways or lateral force to the rod 801 when the rod is located therein, as shown in Fig. 7. (The direction of force being applied is shown by arrow.) The second recess 615 is adapted for application of a generally downward force on the rod 801 when the rod is located therein, as shown in Fig. 6. (The direction of fsrce being applied is shown by arrow.) The third recess 616 is adapted for application of a second generally sideway6 or lateral force to the rod 801 (as shown in ~ig. 8) that is substantially opposite in direction to the firs~
sideways force. It is noted that although the arrows in Figs.
6, 7, and 8 indicate a force that is straight down vertically (Fig. 6) or directly horizontal or sideway6 (Figs. 7 and a)~ it is understood that the force could also be applied at any suitable angle, yet toward the general direction shown. The instrument can also be sliqhtly tilted with respect to the horizontal plane, as shown in Fig. 9, which illustrates a slight upwards force being applied to the rod 801. With a small change in manual orientation of the handle 620, instrument 601 can 201~ 0 selectively apply force against a rod in all 360 about the rod ~01.
As s~own in Fig. ~3, the handle 620 may angle in relation to the distal tip 605 at an angle of about 150. This providas for better visualization of the surgical site by the user of Lhe instrument 601. The tip 605 may include a tip extension 608 interconnecting the tip 605 to the handle 620. Thus. ~he angle between the tip extension 608 and handle 620, as shown, is about 150.
In utilizing the instrument 601, the user passes the rod 801 through the rod receiving opening 610 into the enlarged cavity 612. The user then selects one of the plurality of rod locator reces6es 614, 615, and 616 and locates the rod 801 therein. Force is then applied against the rod in the appropriate desired direction.
It is noted that any suitable materials may be utilized for instrument 601. One such material ;s stainless steel.
Regarding manufacturing methods, any suitable methods may be utilized.
While this invention has been described and exemplified in terms of a particularly advantageous embodiment, those skilled in the art can appreciate that modifications can be made without departing from the spirit and scope of this invention.
