Short-cap nailing device

Abstract

The invention discloses a short-cap nailing device comprising a holder body, a clamping column is arranged at the front end of the holder body. A through hole is formed in the clamping column; an inner edge protrusion is arranged at the end, away from the holder body, of the through hole. A spring is arranged in the through hole; a pressing ball is arranged at the position, corresponding to the inner edge protrusion, of the through hole, a clamping groove is formed in the end, away from the holder body, of the clamping column, the clamping groove is horn-shaped, the through hole is communicated with the side wall of the clamping groove, a nail inlet is formed in the side, close to the clamping groove, of the clamping column, and the clamping groove and the nail inlet penetrate through theside faces of the clamping column. The clamping groove is matched with the pressing ball so that the short-head nail is very easy and convenient to disassemble and assemble, rapid assembly and disassembly are achieved, when the short-head nail is installed, instant friction, vibration and sound are generated between the short-head nail and the pressing ball, whether the short-head nail is successfully clamped or not can be judged according to the sound, judgment of doctors is facilitated to a large extent, and operation time is shortened.

Description

technical field [0001] The invention relates to the field of nail holders, in particular to a short cap nail holder. Background technique [0002] Surgery is the process of entering human tissues through surgical equipment or surgical instruments, expelling lesions, changing structures, or implanting foreign objects by external force. Prosthesis replacement surgery is the process of installing artificial prostheses on the human body with tools to replace diseased tissues and bones. [0003] In some prosthesis replacement operations, it is necessary to use short cap nails to fix the prosthesis on the human body, or use short cap nails to fix surgical tools. Beat and press down to fix the prosthesis or tool. In the existing operation, the doctor usually clamps the short cap nail with a hemostat, and then knocks and presses the short cap nail with a knocking tool.

AI Technical Summary

Problems solved by technology

[0003] In some prosthesis replacement operations, it is necessary to use short cap nails to fix the prosthesis on the human body, or use short cap nails to fix surgical tools. Beat and press down to fix the prosthesis or tool. In the existing operation, the doctor usually clamps the short cap nail with a hemostat, and then knocks and presses down the short cap nail with a knocking tool. The clamping is unstable and there is a certain defect:

[0004] 1. Using hemostats to hold short cap nails during surgery will take up a lot of space and interfere with soft tissues. There is a risk of increased trauma area and slippage leading to injury, which increases the hidden danger of surgical infection and surgical risk of failure;

[0005] 2. If the short cap nails fail to be installed or become loose for a long time, the short cap nails need to be removed and replaced. At this time, new tools are needed to remove the short cap nails. If the short cap nails are bent and damaged during the removal process, it will increase difficulty of removal;

[0006] 3. Use the hemostat to clamp the short-cap nail, resulting in unstable clamping, increased clamping difficulty, increased percussion difficulty, increased nail insertion time, and increased surgical risk;
