radial nerve protective sheath

Abstract

The invention relates to an orthopedic medical device, in particular to a clinical orthopedic musculospiral nerve protective instrument. The invention adopts the technical scheme that a musculospiral nerve protective sheath pipe comprises an upper leaf and a lower leaf, wherein locking stripe convex surfaces (4) of upper leaf combination parts (2) and locking stripe concave surfaces (10) of lower leaf combination parts (8) are locked together to wrap musculospiral nerves between the nerve surface (5) of an upper leaf free part (1) and the nerve surface (11) of a lower leaf free part (7), and the nerve surfaces are combined and fixed through upper leaf combination part locking holes (3) and lower leaf combination part locking holes (9); when the musculospiral nerves are needed to be taken out, the protective sheath pipe is cut off along the inner sides of lock stripes to separate the nerve surfaces (5) and (11) from tissue surfaces (6) and (12) to take out the musculospiral nerves. When the sheath pipe is used for protection, the musculospiral nerves can be protected in primary surgery, postoperation and secondary surgery. Particularly in the secondary surgery, the search difficulty of the musculospiral nerves is reduced. Furthermore, the surgical operation is easy and convenient to master, and the musculospiral nerve protective sheath pipe is suitable for all levels of hospitals. The sheath pipe not only serves as a novel orthopedic nerve protective instrument and but also provides a new way for the department of orthopaedics.

Description

technical field [0001] The invention relates to a medical device for orthopedic surgery, in particular to a radial nerve protection device for clinical orthopedics. Background technique [0002] At present, there is no medical device for protecting the radial nerve at the radial nerve groove of the humeral shaft in clinical orthopedics at home and abroad. Fractures of the middle and lower segments of the humeral shaft are likely to be combined with radial nerve injury. Avoid stretching the radial nerve, which can cause nerve damage. The long-term contact between the radial nerve and the internal fixation plate after operation, and the stimulation by the internal fixation plate for a long time also have a certain impact on nerve function. When the internal fixation plate is removed after the fracture of the middle and lower humerus has healed, the adhesion of the radial nerve to the surrounding tissue increases the difficulty of finding the radial nerve during the operation,...

AI Technical Summary

Problems solved by technology

When the internal fixation plate is removed after the fracture of the middle and lower humerus has healed, the adhesion of the radial nerve to the surrounding tissue increases the difficulty of finding the radial nerve during the operation, which greatly increases the chance of iatrogenic radial nerve injury during the operation and postoperative morbidity. also increased accordingly
