Problems solved by technology

[0002] During osteotomy, the bone is generally cut into a V shape, and the cut bone needs to be reset. In the prior art, when performing reset, the doctor usually holds a pair of pliers in each hand and fixes them to the pedicles respectively. The two curved metal rods on the screw operate, but the two forceps actually move relative to each other. When applied to the spine, it may cause the spine to move, which in turn poses a risk of spinal cord injury, which is very dangerous

Abstract

The invention relates to a reset clamp which comprises two clamp bodies and a calibrated scale, wherein the clamp bodies are mutually hinged. One end of each clamp body is slidably connected with oneside of the calibrated scale, and the other end of each clamp body is fixedly connected with a clamping connection portion for clamping a pedicle screw. The reset clamp is provided with two mutually hinged clamp bodies and the calibrated scale, the clamp can be fixed at nuts of the pedicle screws through the clamping connection portions arranged at the ends of the clamp bodies, fixing and stable resetting can be performed, safety is high, bone marrows are not easily damaged, the clamp is provided with the calibrated scale slidably connected with the clamp bodies, a shape correcting angle can be designed according to actual requirements, so that shapes are corrected, operative effects are improved, and operative risks are avoided.

Description

Technical field [0001] The present invention relates to the technical field of medical devices, in particular to a reduction forceps. Background technique [0002] During an osteotomy operation, the bone is generally cut into a V shape, and the cut bone needs to be reset. In the prior art, when the reset is performed, the doctor usually holds a pair of forceps in each of the two hands, and fixes them to the pedicle. The two curved metal rods on the screw operate, but the two pliers actually move relative to each other. When applied to the spine, it may cause the spine to move, which will cause the risk of spinal cord damage, which is very dangerous. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a reduction forceps to solve at least one of the above technical problems in view of the shortcomings of the prior art. [0004] The technical solution of the present invention to solve the above technical problems is as follows: ...
