Abstract

A minimally invasive hemostat that is easy to disassemble and assemble, it includes a fixed handle and a moving handle, the moving handle is driven and connected to one end of a wire rope extending into the fixed handle through a transmission connecting piece, and the other end of the wire rope is connected to the fixed handle in rotation. The moving tongs on the pliers are driven and connected; the wire rope is connected to the sliding connection wire rope connecting rod located in the fixed handle, the pull rod pin at one end of the transmission connecting piece is clamped on the wire rope connecting rod, the other end of the driving connecting piece is rotationally connected with the moving handle, and the transmission A torsion spring is arranged between the connecting piece and the moving handle so that the pull rod pin clamps the connecting rod of the wire rope. The invention is easy to disassemble and clean, simple to operate, and not cumbersome. It can be equipped with different types of jaws on one handle to meet the needs of medical staff, and achieves the multi-purpose function of one handle. It can also be disassembled to make instrument cleaning more thorough. , At the same time, it can also make it easier for medical staff to use, the clamping force adjustment is reliable and accurate, and the control is flexible, which improves the efficiency of minimally invasive surgery.

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...
