Abstract
The utility model discloses a kind of Multifunctional nerve elevators.It includes the horizontal hook for having the casing of centre bore and being arranged in casing shoe, the elongated slot communicated with centre bore is offered on casing hypomere side wall, inserted with operation knife bar in the centre bore of casing, the bottom of operation knife bar has the horizontal knife stretched out out of elongated slot, the upper end of operation knife bar is stretched out outside casing and top is provided with nut, the spring being pressed between nut and cannula tip is also cased on operation knife bar, operation knife bar can be such that blade is moved back and forth in elongated slot under the action of the spring.After above-mentioned structure, when using, posterior longitudinal ligament is detached, is provoked by horizontal hook, presses upper end nut, you can push blade, cut off posterior longitudinal ligament, its is simple to operate, and intermediary operation need not replace instrument, simplify operating procedure, the separation and excision one step of decompression for making posterior longitudinal ligament are completed, and injured nerve is avoided.
Description
Technical field
The utility model is related to a kind of medical operating apparatus, specifically a kind of Multifunctional nerve elevator.
Background technology
In anterior cervical decompression operation, doctor's generally use nerve dissector detaches posterior longitudinal ligament with dural sac,
It uses gun-type rongeur by posterior longitudinal ligament resection again after separation fully, to appear dural sac, fully depressurizes, existing nerve stripping
Ion has the following disadvantages：Instrument is needed to change when 1, operating；2, space is small when surgical procedure, in the case of blood oozing from the wound surface, then
Using gun-type rongeur easy damaged nerve.
Invention content
The technical problem to be solved by the present invention is to provide a kind of easy to operate and be avoided that the multi-functional of injured nerve
Nerve dissector.
In order to solve the above-mentioned technical problem, the Multifunctional nerve elevator of the utility model includes the set with centre bore
The horizontal hook in casing shoe is managed and be arranged, the elongated slot communicated with centre bore is offered on casing hypomere side wall, casing
Inserted with operation knife bar in centre bore, the bottom for operating knife bar has the horizontal knife stretched out out of elongated slot, operates the upper of knife bar
End is stretched out outside casing and top is provided with nut, operates and is also cased with the spring being pressed between nut and cannula tip on knife bar,
Operation knife bar can be such that blade is moved back and forth in elongated slot under the action of the spring.
Described sleeve pipe is made of the enlarged diameter section positioned at upper semisection and the reduced diameter section positioned at lower semisection.
After above-mentioned structure, operation knife bar due to setting with center hole sleeve, with blade and it is pressed in
Thus spring between nut and cannula tip makes blade stretch out the elongated slot communicated with centre bore and makes behaviour under spring force
Make knife bar drive blade moved back and forth in elongated slot, when in use, horizontal hook by posterior longitudinal ligament detach, provoke, press upper end
Nut, you can blade is pushed, cuts off posterior longitudinal ligament, simple to operate, intermediary operation need not replace instrument, simplify
Operating procedure makes the separation of posterior longitudinal ligament be completed with excision one step of decompression, avoids injured nerve.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model Multifunctional nerve elevator.
Specific implementation mode
With reference to the accompanying drawings and detailed description, the Multifunctional nerve elevator of the utility model is made further detailed
Explanation.
As shown, the Multifunctional nerve elevator of the utility model, includes the casing 2 with centre bore 1 and setting
In the horizontal hook 3 of casing shoe, casing 2 is made of the enlarged diameter section positioned at upper semisection and the reduced diameter section positioned at lower semisection,
The elongated slot 4 communicated with centre bore is offered on 2 hypomere side wall of casing, the length of elongated slot is arranged as required to, the centre bore of casing 2
It is interior inserted with operation knife bar 5, the bottom of operation knife bar 5 has the horizontal knife 6 stretched out out of elongated slot, operates the upper end of knife bar 5
It stretches out outside casing 2 and top is provided with nut 7, operate and be also cased with the spring being pressed between nut and cannula tip on knife bar 5
8, normal condition, spring 8 can make operation knife bar be in impaction state, when needing to cut off longitudinal ligament, pressing top
Nut 7 make operation knife bar 5 overcome spring force drive blade move down along elongated slot.
