Abstract

An acute nerve dissector not only has the function of dissecting nerves and soft tissues as the same as the common nerve dissector, but also is capable of effectively cutting apart the soft tissues (such as longitudinal ligament, ligamentum flavum and the like) closely related to the nerves so that the soft tissues can be cut off by other tools easily. The technical scheme employed by the acute nerve dissector is as follows: the head part of the nerve dissector is improved so that an acute dissecting area is added above the head part; the upper part and the front part of the acute dissecting area are acute edges so that the acute dissecting area is capable of performing cutting operations; the acute dissecting area is 1 mm high, and the front end thereof has a distance of 1 mm away from the front end of the head part of the nerve dissector; therefore, when the head end of the nerve dissector is inserted between a dura mater or a nerve and a soft tissue, as the nerve dissector is propelled forward, the acute dissecting area above the head part is capable of cutting apart the soft tissue to expose the dura mater or the nerve, and simultaneously, stress is relieved and the operation efficiency is improved. As the acute dissecting area is separated from the dura mater or the nerve by the head end of the nerve dissector, no damage may be caused on the dura mater or the nerve; therefore, the acute nerve dissector has high safety.

Description

Sharp property nerve is peeled off son

Affiliated technical field

This utility model belongs in the spinal surgery process on nerve or dura mater surface and carries out the instrument that ligament and soft tissue are peeled off, and in use has safety and characteristics of high efficiency.

Background technology

Present employed common nerve is peeled off son and is processed by an elongated flat metal rod usually, and function is mainly the adhesion that separates between nervous tissue or dura mater and ligament and the soft tissue, and nerve or dura mater are retracted, and its operation has light and handy and careful characteristics.In the spinal surgery process; In the time of need carrying out nerve decompression; The hand-held nerve of doctor is peeled off the son middle part; Push nerve aside with the ionic head of neural stripping, perhaps separate the adhesion between nerve and the soft tissue, nerve is produced the tissue (intercalated disc, ligament, osseous tissue etc.) of compressing with other instrument excision then.For some narrow and small position, when using nerve to peel off son to separate, need cause appear (when for example throat road disc excision exposes dura mater) of the excision of pressing thing or nervous tissue simultaneously.Yet,, using the neural son of peeling off to carry out the isolating soft tissue that goes to cut neural surface with another instrument simultaneously and have difficulties because the working place is limited; Particularly when canalis spinalis angular vein clump is hemorrhage; Also to use suction pump to suck blood, make the working place more narrow and small, operating difficulties; Operation efficient reduces, and also is easy to generate nerve injury.

Summary of the invention

In order to enlarge the ionic scope of application of neural stripping, expand its function of use, improve service efficiency and safety in narrow and small working place, this utility model provides a kind of sharp property nerve to peel off son, accomplishes the separation and the incision of soft tissue simultaneously in narrow and small zone.

The technical scheme that this utility model adopted is: the ionic head of common neural stripping is improved, increase a sharp property stripping area in above-head.Like this; When nerve being shelled between ionic head insertion dural sac or neural and the soft tissue (for example posterior longitudinal ligament, ligamenta flava etc.); The sharp keen stripping area of its top can directly cut ligament or other soft tissue; Expose dura mater or nerve, and remove compressing, can further excise soft tissue at an easy rate with other instrument on this basis.

Through as above improving design, can be more efficiently to separating with nervous tissue soft tissue in close relations in the narrow and small zone and cut, and raising operation safety.

The specific embodiment

In concrete operative process; Nerve is shelled ionic head to be inserted between target soft tissue (for example posterior longitudinal ligament, ligamenta flava etc.) and dura mater or the nerve; In the adhesion organization that separates between it, nerve to be peeled off son push ahead or upwards provoke, the sharp property stripping area of above-head can cut soft tissue; Remove nerve compression, avoid dura mater or neural damage simultaneously.

Claims

1. sharp property nerve is peeled off son, and the ionic head of common neural stripping is improved, and it is characterized in that: increase a sharp property stripping area in above-head, act as the soft tissue that is positioned at its top or the place ahead is cut.

2. sharp property nerve according to claim 1 is peeled off son, it is characterized in that: the top of sharp property stripping area can be carried out cutting operation with anterior for sharpened edge, and it highly is 1mm, and its front end and nerve are peeled off sub-head front end apart from 1mm.
