In figure: 1. outer tube, 2. inner tube, 3. inner core, 4. bell, 5. outer main body, 6. interior main body, 7. through hole, 8. elastic arm, 9. gim peg, 10. ear.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described, so that those skilled in the art can better understand the present invention also, can be implemented, but illustrated embodiment is not as a limitation of the invention.
As depicted in figs. 1 and 2, in of the present invention one implements, the scope gatherer comprises the outer tube 1 of both ends open, and the front end of outer tube 1 is coniform; Also be provided with inner tube 2 in outer tube 1, it is coniform that the front end of inner tube 2 also is, and the opening internal diameter of the external diameter of inner tube 2 and outer tube 1 front end adapts, and inner tube 2 can be passed from the opening of outer tube 1 front end, and the length of inner tube 2 is greater than the length of outer tube 1.In use, outer tube 1 is enclosed within to the outside of inner tube 2, the coniform outer surface of outer tube 1 front end and the coniform outer surface formation of inner tube 2 front ends are seamlessly transitted, then inner tube 1, outer tube 2 are together inserted to patient's cranial cavity from the operative incision of patient's head, now, the effect of inner tube 2 is openings of blocking outer tube 1 front end, prevents the outer tube 1 damage patient's of opening cerebral tissue.After arriving desired depth, outer tube 1 is fixing, and inner tube 2 is taken out, can have been performed the operation by outer tube 1 importing scope or other operating theater instruments.The length of inner tube 2 is greater than the length of outer tube 1, is for ease of taking out inner tube 2.
As to further improvement of the present invention, can be by the two ends of inner tube 2 also opening, and the opening part in inner tube 2 rear ends arranges syringe adapter.So, in use, can first inner tube 2 be inserted to patient's cranial cavity, syringe be received on the syringe adapter of inner tube 2 rear ends, to utilize syringe, draw a part of intracranial edema liquid, reduce cranial cavity pressure.And then outer tube 1 is enclosed within inner tube 2 from inner tube 2 rear ends, slowly outer tube 1 is inserted to cranial cavity, thereby greatly reduce patient's misery, and can reduce damage and the risk caused to the patient.Wherein, as shown in Figure 1, syringe adapter is preferably a bell 4 that is arranged on inner tube 2 rear ends.Syringe adapter can also be other structure, such as one section flexible pipe etc.
In addition, the present invention can also further optimize, and for example an inner core 3 can be set in inner tube 2, and the opening internal diameter of the external diameter of inner core 3 and inner tube 2 front ends adapts, and the front end of inner core 3 is curved.The effect of inner core 3 is to block the opening of inner tube 2 front ends when inner tube 2 is inserted cranial cavity, prevents the inner tube 2 damage patients' of opening cerebral tissue.After being inserted into precalculated position, inner core 3 is taken out and gets final product.Therefore, for the convenient inner core 3 that takes out, the length of inner core 3 should be greater than the length of inner tube 2.
For when performing the operation, that outer tube 2 is relative with patient's head fixing, so that operation can outer tube 1 arranged outside be connected and fixed device, for outer tube 1 being connected and is fixed on the operative incision place of patient's head.This is connected and fixed device can have various structures to realize, comparatively preferably be connected and fixed device and comprise the main body that is provided with through hole 7, outer tube 1 is located in this through hole 7, at the main body periphery, is provided with connector.Connector is fixed on patient's head for being connected and fixed device.As a kind of preferred embodiment of connector, as shown in Figure 3, this connector is semiorbicular elastic arm 8.During use, extruding elastic arm 8, shrink elastic arm 8, then this is connected and fixed to the opening part that device is put into patient's skull, unclamps elastic arm 8, and elastic arm 8 tops are pressed on patient's skull, utilize elastic arm 8 elastic force will be connected and fixed device and are fixed on skull.For convenient extruding elastic arm 8, ear 10 can be set in the inboard of elastic arm 8.Certainly, connector can be also other version, and for example mobilizable dentation, can grab the long claw-like at patient's head, or adopts medical proof fabric fixing etc.
Refer to Fig. 3 again, as to being connected and fixed the further improvement of device, main body can be divided into to two parts, interior main body 6 and outer main body 5, form spherical joint between interior main body 6 and outer main body 5, and through hole 7 is arranged on interior main body 6.So, after being connected and fixed device and being fixed on patient's head, the spherical joint adjustment that can form by inside and outside main body is through the angle of the outer tube 1 of through hole on interior main body 6, thereby more flexible in use.Carry out for convenient operation, be provided on main body 5 outside interior main body 6 and the relatively-stationary gim peg 9 of outer main body 5.After adjusting the angle of outer tube 1, by gim peg 9, by endosome body 6 and outer main body 5 lockings, make its activity relatively again, so that the doctor carries out operation technique.
The above embodiment is only the preferred embodiment for absolutely proving that the present invention lifts, and protection scope of the present invention is not limited to this.Being equal to that those skilled in the art do on basis of the present invention substitutes or conversion, all within protection scope of the present invention.Protection scope of the present invention is as the criterion with claims.
