Fracture reduction forceps and combined fracture reduction instrument

Abstract

The invention relates to fracture reduction forceps. The fracture reduction forceps comprise a left forcep body, a right forcep body and a positioning plate; the left forcep body is hinged to the right forcep body; the left forcep body comprises a first forcep rod and a second forcep rod; the right forcep body comprises a third forcep rod and a fourth forcep rod; the first forcep rod is hinged to the second forcep rod; the third forcep rod is hinged to the fourth forcep rod; a pressing plate which can move vertically along the second forcep rod is arranged on the second forcep rod; a clamping body is arranged at each of the end parts of the second forcep rod and the fourth forcep rod; one end of the positioning plate is fixedly connected with the fourth forcep rod; the other end of the positioning plate is connected with the third forcep rod. The invention further relates to a combined fracture reduction instrument. According to the fracture reduction forceps and the combined fracture reduction instrument, a bone is clamped stably; the structural design and the functional design are optimized; after a bone stump is clamped by the reduction forceps, the interference with subsequent operation can be avoided; the operation of a user is facilitated; manpower is saved; the efficiency is improved; the positioning effect is better.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a fracture reduction forceps, and also to a combined fracture reduction device. Background technique [0002] At present, the fracture reduction forceps used clinically have various shapes, such as pointed, flat, and curved. However, such devices currently used in clinical practice have the following problems: [0003] 1. Because the structural design and functional design of the existing reduction forceps are too simple, the broken ends of the clamped bones are mostly in contact with points or small areas, so it is easy to cause unstable clamping, and manpower is still required to continue to hold after reset, and the operator is prone to fatigue ; [0004] 2. Due to the fixed structure of the clamp body itself, there is interference with the steel plate to be fixed, which affects the insertion of the fixed steel plate, and requires multiple people to assist in the ope...

Problems solved by technology

[0003] 1. Because the structural design and functional design of the existing reduction forceps are too simple, the broken ends of the clamped bones are mostly in contact with points or small areas, so it is easy to cause unstable clamping, and manpower is still required to continue to hold after reset, and the operator is prone to fatigue ;

[0004] 2. Due to the fixed structure of the clamp body itself, there is interference with the steel plate to be fixed, which affects the insertion of the fixed steel plate, and requires multiple people to assist in the operation at the same time, wasting manpower and low efficiency;

[0005] 3. When the existing reduction forceps are removed from the manual control, the reduction is easy to be lost, and the fracture reduction is often repeated, which not only increases the operation time, but also tends to increase the amount of bleeding during the operation, excessive soft tissue damage during the operation, and postoperative Poor recovery and other adverse outcomes
