Problems solved by technology

[0003] Minimally invasive hemostatic forceps are often used in precise surgical operations on the eye and brain. Limited by the operating environment, such operations generally have a narrow and complicated operating space, and the use of instruments has a small stroke and high precision requirements. It will lead to the failure of the operation, so the convenience, controllability and stability of the minimally invasive hemostat operation directly affect the quality of the operation

Abstract

The invention discloses minimally invasive hemostatic forceps convenient to assemble and disassemble. The minimally invasive hemostatic forceps comprise a fixed handle and a movable handle, the movable handle is connected with one end of a steel wire rope extending into the fixed handle in a driving mode through a transmission connecting plate, and the other end of the steel wire rope is connectedwith a movable forceps clip rotatingly connected to a fixed forceps clip in a driving mode; the steel wire rope is connected with a steel wire rope connecting rod slidingly connected to the fixed handle, a pulling rod pin located at one end of the transmission connecting plate is clamped to the steel wire rope connecting rod, the other end of the transmission connecting plate is rotatingly connected with the movable handle, and a torsion spring enabling the pulling rod pin to clamp the steel wire rope connecting rod is arranged between the transmission connecting plate and the movable handle.The minimally invasive hemostatic forceps are convenient to disassemble and clean, easy to operate and is not cumbersome; different types of jaws can be mounted on one handle to meet the use requirement of a medical worker, the function of a multi-purpose handle is achieved, the instrument can be thoroughly cleaned through disassembly, meanwhile the medical worker can use the forceps more easily,adjustment of clamping force is reliable and accurate, control is flexible, and the efficiency of a minimally invasive surgery is improved.

Description

technical field [0001] The invention relates to medical hemostatic forceps, in particular to a minimally invasive hemostatic forceps which are easy to assemble and disassemble. Background technique [0002] The hemostat is a general-purpose instrument in the medical device industry, and is usually suitable for needle-held suture operations. The minimally invasive hemostat is a special type of hemostat used in fine microscopic clinical operations. [0003] Minimally invasive hemostatic forceps are often used in precise surgical operations on the eye and brain. Limited by the operating environment, such operations generally have a narrow and complicated operating space, and the use of instruments has a small stroke and high precision requirements. It will lead to the failure of the operation, so the convenience, controllability and stability of the minimally invasive hemostat operation directly affect the quality of the operation. [0004] This patent application is a technic...
