Technical Field

The invention relates to the field of nail holders, in particular to a short-cap nail holder.

Background

Surgical procedures are procedures in which a lesion is expelled, a structure is changed, or a foreign object is implanted by means of an external force through a surgical device or a surgical instrument into a human tissue. Prosthesis replacement surgery is a process of installing an artificial prosthesis on a human body using a tool to replace diseased tissue, bone.

In some prosthesis replacement operations, a short cap nail is needed to fix the prosthesis on a human body, or a short cap nail is used to fix an operation tool, the short cap nail is firstly clamped in a specific fixing process, then the short cap nail is knocked down by the tool, the prosthesis or the tool is fixed, in the existing operation, a doctor usually uses a hemostatic forceps to clamp the short cap nail, then the knocked tool is used to knock down the short cap nail, the clamping is unstable, and certain defects exist:

firstly, when the short cap nail is held by using a hemostatic forceps in an operation, a large space is occupied, soft tissues are interfered, the wound area is at a risk of increasing, the risk of injury caused by slipping is also increased, and the hidden danger of operation infection and the risk of operation failure are increased;

secondly, the short cap nail is not installed or loosened for a long time, the short cap nail needs to be taken down for replacement, a new tool is needed to take down the short cap nail, and if the short cap nail is bent and damaged in the taking-down process, the taking-down difficulty is increased;

thirdly, the short cap nail is clamped by the hemostatic forceps, so that unstable clamping is caused, the clamping difficulty is increased, the knocking difficulty is increased, the nail inserting time is prolonged, and the operation risk is increased;

the invention discloses a short cap nailing holder which is used for solving the problems.

Disclosure of Invention
