Abstract

The utility model provides a kind of nerve dissector, body is removed including stripping head, removing handle and two strips, inverted " v " shape is bent into the middle part of removing handle, the two sides for removing handle are made to form the first shaft arm and the second shaft arm of intersection, the both ends for removing handle are connect with one end of removing body respectively, and the other end for removing body links together with stripping head respectively.Using the technical solution of the utility model, medical staff is when in use, same root nerve or dura mater can be retracted by two stripping heads, two nerves or rupture of membranes can also be made to be retracted simultaneously by two stripping heads, to increase neurosurgery space, keep traction space larger, and handle is removed through having elasticity after bending, convenient for the distance between traction point is adjusted, medical staff is facilitated to operate, when on the shelf, then it can directly be hung up and be placed by removing handle, convenient for storage.

Description

A kind of nerve dissector

Technical field

The utility model belongs to the field of medical instrument technology more particularly to a kind of nerve dissector.

Background technique

Nerve dissector main function is the adhesion between separation nerve fiber or dura mater and ligament and soft tissue, and Nerve or dura mater are retracted, operation has the characteristics that light and handy and careful.However, general neural elevator used at present is logical The elongated flat metal rod of Chang Youyi root and sharp property removing head are made, and in neurosurgery process, the easy bleeding of vein is this Elevator is only capable of to retract at nerve or epidural certain point when in use, and the operating space of traction is very narrow and limited, Visibility is poor during operation, operating difficulties.Procedure efficiency reduces, and is also easy to generate neurotrosis.

Utility model content

In order to solve the above technical problems, the utility model provides a kind of nerve dissector.

The utility model is achieved by the following technical programs.

The utility model provides a kind of nerve dissector, mainly includes stripping head, removing handle and two strip removings Body is bent into inverted " v " shape in the middle part of the removing handle, and the two sides of the removing handle is made to form the first shaft arm and second of intersection The both ends of shaft arm, the removing handle are connect with one end of removing body respectively, and the other end of the removing body connects with stripping head respectively It is connected together.

First shaft arm and the second shaft arm angle of intersection are less than 20 °.

The first shaft arm length and the second shaft arm equal length.

The ratio between the length of the removing handle and width are greater than 25:1.

The ratio between the length of the removing handle and thickness are greater than 250:1.

The stripping head is spoon shape shape, and inner concave is towards the removing handle width direction.

The removing body cross section is circle.

The length ratio of the length of the removing handle and the removing body are as follows: 4:1 to 8:1.

The material of the stripping head, removing handle and removing body is the stainless steel that the trade mark is 304.

The stripping head, removing handle and removing body are integrally formed manufactured.

The utility model has the beneficial effects that: medical staff when in use, can using the technical solution of the utility model By two stripping heads to same root nerve or dura mater retract, can also pass through two stripping heads simultaneously make two nerves or Rupture of membranes is retracted, and to increase neurosurgery space, since stripping head position is two o'clock, keeps traction space larger, and And removing handle has elasticity later through bending, convenient for the distance between traction point is adjusted, so as to adjust space is retracted Size facilitates medical staff to be operated, in addition, when stripping head provided by the utility model is idle, it can be directly by it The utility model is removed the hang-up of handle middle part and is placed, and the utility model has structure simple, easy to use, convenient for placement and carrying etc. Advantage.

Fig. 3 is the left view of the utility model；

Fig. 4 is the partial enlarged view of the utility model Fig. 3.

In figure: 1- stripping head, 2- remove handle, and 3- removes body, the first shaft arm of 201-, the second shaft arm of 202-.

Specific embodiment

Be described further below the technical solution of the utility model, but claimed range be not limited to it is described.

As shown in Figure 1, Figure 2, Figure 3, Figure 4, the utility model provides a kind of nerve dissector, including stripping head 1, removing handle 2 and two strips remove bodies 3, the middle part of removing handle 2 is bent into inverted " v " shape, and the two sides for removing handle 2 is made to form intersection First shaft arm 201 and the second shaft arm 202, the both ends for removing handle 2 are connect with one end of removing body 3 respectively, remove the other end of body 3 It links together respectively with stripping head 1.

Using the technical solution of the utility model, medical staff when in use, can be by two stripping heads to same root mind Through or dura mater retracted, can also pass through two stripping heads simultaneously so that two nerves or rupture of membranes is retracted, to increase nerve Surgical space keeps traction space larger since stripping head position is two o'clock, and removes handle through having bullet after bending Property, convenient for the distance between traction point is adjusted, so as to adjust the size for retracting space, medical staff is facilitated to perform the operation Operation, in addition, will directly can hang up and put in the middle part of its utility model removing handle when stripping head provided by the utility model is idle It sets, the utility model has structure simple, and it is easy to use, the advantages that convenient for placement and carrying.

Further, the first shaft arm 201 and 202 angle of intersection of the second shaft arm are less than 20 °.First shaft arm, 201 length and the Two shaft arms, 202 equal length.The ratio between length and the width for removing handle 2 are greater than 25:1.The ratio between the length of removing handle 2 and thickness are greater than 250:1.Using the technical solution, making to remove handle has good elasticity, when in use, medical staff can control pick-up point it Between spacing, can be by the way that the utility model be hung up in the middle part of removing handle when idle so as to adjust the size of pull-up space, side Just it stores.

Further, stripping head 1 is spoon shape shape, and inner concave is towards removing 2 width direction of handle.It is transversal to remove body 3 Face is circle.Remove the length of handle 2 and the length ratio of removing body 3 are as follows: 4:1 to 8:1.In addition, also being set on removing handle outer surface There are several anti-skid bulges, is conducive to medical staff and operates.

Further, the material of stripping head 1, removing handle 2 and removing body 3 is the stainless steel that the trade mark is 304.Stripping head 1, it removes handle 2 and removing body 3 is integrally formed manufactured.Using the technical solution, be conducive to carry out the utility model clear It washes and disinfects, extensively, manufacturing cost is cheap for 304 stainless steel materials materials.
