Problems solved by technology
Although ligation clips made of metal materials have high clamping strength, they are often small in size and the edges are too sharp, which will cause mechanical damage to blood vessels during use
Ligation clips made of medical plastics are usually made too large in order to meet greater clamping strength, which affects the operator's surgical field of view and is not conducive to clamping small blood vessels

Provided is a ligature clamp. The ligature clamp comprises a V-shaped clamp body integrally formed by a first arc-shaped clamp arm and a second arc-shaped clamp arm, a clamp hook and a clamp head are arranged at the free end of the first arc-shaped clamp arm and the free end of the second arc-shaped clamp arm respectively, a first reinforcer is arranged inside the first arc-shaped clamp arm, and a second reinforcer is arranged inside the second arc-shaped clamp arm. The ligature clamp is provided with an improved structure, and the reinforcers in the ligature clamp enable the ligature clamp to have better strength and better toughness and enable the ligature clamp to meet the requirements of various sizes under the condition of guaranteeing the strength and the toughness. Meanwhile, the invention further provides a manufacturing method of the ligature clamp.
Description
technical field [0001] The invention relates to a surgical medical instrument, in particular to a method for manufacturing a clip used to close a blood vessel or tissue during a surgical operation, and a ligation clip manufactured by the method. The ligation clip can be clinically used for anastomosis and ligation of blood vessels and tissues during internal surgical operations. In practical applications, the ligation clip is also commonly referred to as a blood vessel clip, a ligation buckle, a surgical lock clip, a tissue clip, and the like. Background technique [0002] In order to fully expose the surgical field of view during the surgical operation, it is necessary to ligate the broken blood vessels in the incision to prevent bleeding. Hemostasis technology has become one of the cores of basic surgical techniques, and surgical operations on any part of the human body almost without exception involve bleeding and hemostasis. Generally, the broken blood vessel is clampe...
