Problems solved by technology

[0004] The main tool for fracture reduction surgery is the reduction forceps, but the reduction forceps can only clamp the proximal end of the fixed bone. When the anatomical plate swings around its own head on the bone, it is difficult to detect with the naked eye
At this time, after fixing the tail end of the anatomical plate to the proximal end of the bone, it will cause the distal and proximal ends of the bone to deviate and cannot return to the original position before the fracture

Abstract

The invention provides locating assisting pliers and relates to the technical field of medical appliances. The locating assisting pliers comprise a first plier arm, a second plier arm, a locating mechanism and a guiding mechanism, wherein the first plier arm and the second plier arm are hinged to each other and are separately connected with the locating mechanism; the guiding mechanism is arrangedon the locating mechanism; and during swinging of the second plier arm relative to the first plier arm, a drilling bit penetrates through the guiding mechanism and can always point to a midpoint position between the first plier arm and the second plier arm. According to the locating assisting pliers provided by the invention, a spatial position of the guiding mechanism is limited by using the locating mechanism, so that the drilling bit penetrating through the guiding mechanism can be accurately located at the midpoint position between the first plier arm and the second plier arm, and the accuracy of mounting of a shaped plate for dissection is guaranteed. Based on the locating assisting pliers, the invention further provides a resetting kit for a bone fracture surgery.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a positioning auxiliary forceps and a reset suit for fracture surgery. Background technique [0002] In fracture reduction surgery, anatomical plates are usually used to respectively fix the distal end and the proximal end of the broken bone, so that the bone can be accurately reset and fixed. [0003] The specific operation process of the operation is: first fix the head end of the anatomical plate to the distal end of the bone with screws, and then fix the tail end of the anatomical plate to the proximal end of the bone with screws, so that the bone recovers and is fixed in its original position . [0004] Clinically, the tool for fracture reduction surgery is mainly the reduction forceps, but the reduction forceps can only clamp the proximal end of the fixed bone. When the anatomical plate swings around the head end of itself on the bone, it is difficult to detect...
