[0007] The arc-shaped grooves are chamfered at both ends and between the stripping head.

[0008] Two or three or four arc-shaped grooves are provided on the side wall of the stripping head along the circumferential direction.

[0009] The handle, connecting rod and stripping head are integrally machined and formed.

[0010] The handle, connecting rod and stripping head are made of titanium alloy material.

[0011] Anti-slip texture is provided on the handle.

[0012] The utility model discloses the above -mentioned structure can bring following beneficial effect:

[0013] By being equipped with arc -shaped groove on the lateral wall of the flat round peeling head, not only can the nerve or blood vessel be separated through the flat round peeling head, but also the separated nerve or blood vessel can be placed in the arc -shaped groove, and the arc -shaped groove can effectively prevent the nerve or blood vessel from slipping, and further, the functions of convenient separation and anti -slipping are considered.

[0020] In order to more clearly illustrate the overall concept of the utility model, the following detailed description is carried out in the form of example in conjunction with the drawing of the specification.

[0021] In the following description, a lot of specific details are set forth in order to fully understand the utility model, however, the utility model can also be implemented in other ways different from the description herein, therefore, the protection scope of the utility model is not limited by the following disclosed specific embodiments.

[0022] Each embodiment in the specification adopts progressive mode and describes, and the same similar parts between each embodiment are mutually referred to, and each embodiment emphasizes the difference with other embodiments.

[0023] In addition, the terms "end", "circumferential direction" and the like are only used for the purpose of description, and cannot be understood as indicating or suggesting relative importance or implicitly indicating the position of the indicated technical features.

[0024] In the utility model, unless another definite provision and limitation, the term "is equipped with", "is arranged", "is connected" and so on term should do broad sense understanding, for example, can be fixed connection, also can be detachable connection, or is integrated;Can be mechanical connection;Can be direct connection, also can be indirectly connected through intermediate medium.

[0025] As shown in Figures 1-4 A neurosurgery micro dissection head, comprising a handle 1, the handle 1 is connected with connecting rod 2, the connecting rod 2 end is equipped with dissection head 3, the dissection head 3 is designed into flat round, at least one arc groove 4 is arranged on the side wall of the dissection head 3, a plurality of arc grooves 4 are arranged along the circumferential direction, the flat round dissection head 3 separates nerve or blood vessel 5, and the separated nerve or blood vessel 5 is arranged in the arc groove 4.Compared with the prior art micro dissection head 8, by arranging the arc groove 4 on the side wall of the flat round dissection head 3, not only the nerve or blood vessel 5 can be separated by the flat round dissection head 3, but also the separated nerve or blood vessel 5 can be placed in the arc groove 4, and the arc groove 4 can effectively prevent the nerve or blood vessel 5 from slipping, thereby achieving the functions of convenient separation and anti-slip.

[0026] The two ends of the arc groove 4 and the dissection head 3 are chamfered 6.The chamfer 6 eliminates the relatively sharp excess segment, effectively avoiding damage to the nerve or blood vessel 5.

[0027] Two or three or four arc grooves 4 are arranged on the side wall of the dissection head 3 along the circumferential direction.In actual application, the position and number of the nerve or blood vessel 5 are different, and the multiple arc grooves 4 can be flexibly selected according to the actual situation, and the operation is more convenient and flexible.

[0029] The handle 1, the connecting rod 2 and the dissection head 3 are made of titanium alloy material, which has good corrosion resistance and high temperature resistance, and high hardness and is not easy to rust.

[0030] The handle 1 is provided with anti-slip texture 7.The anti-slip texture 7 can effectively increase the friction between the handle 1 and the palm, thereby playing the anti-slip effect.

[0031] The neurosurgery micro dissection head of the application is used as follows:

[0032] In actual application, the nerve or blood vessel 5 is separated by the flat round dissection head 3, and then the separated nerve or blood vessel 5 is rotated into the arc groove 4 of the dissection head 3 (as Figure 4The two protruding parts (as shown) further play a good anti-slip function.

[0033] The specific embodiments described above cannot be used as a limitation on the scope of protection of the utility model, and any alternative improvement or transformation made by the skilled in the art to the embodiments of the utility model falls within the scope of protection of the utility model.
