Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical devices, and particularly relates to a double-headed nerve dissector. Background Art
[0002] A nerve dissector is a medical device commonly used in neurosurgery. It is mainly used to dissect spinal nerve tissues or nerve membranes for surgical operations or treatments. Its tip is usually relatively thin and can finely separate and protect nerves.
[0003] A nerve dissector is usually made of a slender metal rod to be able to reach into a narrow operating space for operation. During spinal surgery, when nerve decompression is required, the doctor holds the middle part of the nerve dissector and uses the head of the nerve dissector to separate the nerve or separate the adhesion between the nerve and soft tissues. However, the traditional nerve dissector lacks flexibility and cannot adapt to the curves and morphological changes of different nerve structures, making it more laborious and time-consuming for doctors to operate.
[0004] Therefore, a double-headed nerve dissector is proposed. Content of the Utility Model
[0005] Aiming at the deficiencies of the prior art, the utility model provides a double-headed nerve dissector to solve the above problems.
[0006] To achieve the above purposes, the utility model is realized through the following technical solutions: A double-headed nerve dissector includes an elbow hook part, a holding handle, and a straight head dissection part. Grooves for connecting with the elbow hook part and the straight head dissection part are respectively opened at both ends of the holding handle. The elbow hook part and the straight head dissection part are respectively welded and fixed to both ends of the holding handle. The elbow hook part includes a 120-degree elbow, a hook rod, and an elbow positioning groove. The straight head dissection part includes a straight head, a dissection rod, and a straight head positioning groove. A rectangular holding groove for the doctor to hold is opened in the middle of the holding handle.
[0007] Based on the above technical solutions, the utility model also provides the following optional technical solutions:
[0008] Further technical solution: The 120-degree elbow and the hook rod are set as a seamless integrated part through heat treatment. The head of the 120-degree elbow is thin and flat, and the front end is passivated. The straight head and the dissection rod are set as a seamless integrated part through heat treatment. The head of the straight head is thin and flat, and the front end is passivated.
[0009] Further technical solution: The elbow positioning groove is arranged at one end of the hook rod away from the 120-degree elbow and is a rectangular groove. The elbow positioning groove corresponds to a rectangular positioning block fixedly connected inside the groove at one end of the holding handle. The straight head positioning groove is arranged at one end of the peeling rod away from the straight head and is a conical groove. The straight head positioning groove corresponds to a conical positioning block fixedly connected inside the groove at the other end of the holding handle.
[0010] Further technical solution: The surface of the holding handle is provided with anti-slip lines, and the anti-slip lines are arranged in a fine grid shape.
[0011] Further technical solution: The width of the rectangular holding groove is 5 mm, the length is 20 mm, and the depth is 2 mm.
[0012] Further technical solution: A number of semi-circular grooves are arranged on the outer side of one end of the holding handle close to the elbow hook pulling part, and the depth of the semi-circular grooves is 1.5 mm.
[0013] Further technical solution: Scale marks for helping doctors accurately master the peeling depth and position are marked on the surfaces of the hook rod and the peeling rod.
[0014] Further technical solution: The outer surfaces of the elbow hook pulling part and the straight head peeling part are both made smooth and sterile.
