Problems solved by technology

[0003] The problems and shortcomings of the first method are: the gauze is not fixed firmly enough, and it is easy to fall off during the operation; the gauze is not fixed accurately enough, and it is easy to cause problems such as dislocation; the doctor needs to wrap the gauze during the operation, which increases the burden on the doctor
The problems and shortcomings of the second method are: there are requirements for the type of hemostat, and it cannot be compatible with any type of hemostat; the holding distance is limited by the length of the tail clamp, and most of the required clamping distance cannot be achieved. distance coverage
[0004] In summary, the existing hemostats lack an auxiliary device that can fix the hemostat firmly without increasing the burden on doctors and is suitable for any type of hemostat

Abstract

The invention relates to a self-locking device of hemostatic forceps. An upper sliding rail and a lower sliding rail are connected in a shell of the self-locking device in an up-down sliding mode. Aninner-ratchet outer-gear structure is meshed between the upper sliding rail and the lower sliding rail, and a driving assembly is connected in the inner-ratchet outer-gear structure. The self-lockingdevice for hemostatic forceps is more convenient to operate, improves operation efficiency and allows a doctor to quickly complete temporary fixation of bones. According to the invention, self-lockingfunction for hemostatic forceps with any size can be achieved.

Description

technical field [0001] The patent of the present invention relates to a medical device for orthopedic surgery, in particular to a self-locking device for hemostatic forceps and its usage method. Background technique [0002] At present, the orthopedic doctor usually adopts two methods when performing temporary fixation of the bone: 1. After the doctor uses the hemostat to clamp the bone as a temporary fix, the doctor wraps the hand part of the hemostat with gauze and fixes it. 2. Use a hemostat with a tail clip. [0003] The problems and disadvantages of the first method are: the gauze is not fixed firmly enough, and it is easy to fall off during the operation; The problems and shortcomings of the second method are: there are requirements for the type of hemostat, and it cannot be compatible with any type of hemostat; the holding distance is limited by the length of the tail clamp, and most of the required clamping distance cannot be achieved. distance coverage. [0004] ...
