Problems solved by technology

[0003] At present, in the actual operation, the doctor needs to choose a suture needle with a suitable radian for the operation. During the operation, the doctor needs to control the clamping angle between the needle tip and the holder by clamping at different positions of the suture needle. For wounds, clamping in the middle or near the front of the suture needle may cause inconvenient operation. Therefore, this application provides a medical suture needle with variable clamping angle to meet the demand

Abstract

The invention discloses a medical suture needle with a variable clamping angle, and relates to the technical field of medical suture needles. The medical suture needle comprises a plurality of cylindrical rods; a needle tip mechanism is mounted at one end of the first cylindrical rod; ball grooves are formed in the ends, close to each other, of every two adjacent cylindrical rods; a same rotating ball is installed on the inner walls of every two adjacent ball grooves in a matched mode; suture needle rotating parts are installed on the plurality of cylindrical rods; and each suture needle rotating part comprises a needle body rotating unit, a rotating limiting unit and a limiting control unit which are connected. The medical suture needle is reasonable in structure, the structure of the medical suture needle is simple, the clamping angle between a needle tip and a clamp can be changed by adjusting the radian of the suture needle, the radian is adjusted in advance according to the needed clamping angle, and therefore the suture needle with the most appropriate radian can be selected for an operation; and the suture quality of the operation is improved, and a doctor can operate more smoothly in the operation process.

Description

technical field [0001] The invention relates to the technical field of medical suture needles, in particular to a medical suture needle with a variable clamping angle. Background technique [0002] Most of the suture needles are made of stainless steel wires drilled or slotted at the end of the needle. The surface is polished and electrolytically treated. Suture needles are one of the indispensable instruments in the operation process, and suture is one of the most basic operations in surgery. , almost all operations require the use of suture needles and suture thread for ligation and suture. According to the requirements of the operation, choosing a suitable suture needle is the basic condition to ensure the smooth progress of the operation. Therefore, it is necessary to provide a suture needle with good practicability. Doctors use. [0003] At present, in the actual operation, the doctor needs to choose a suture needle with a suitable radian for the operation. During the ...
