Description

An improved forceps head structure on electrocoagulation forceps

Technical field:

The invention relates to the technical field of medical high-frequency instruments, and more specifically relates to an improved clamp head structure on electrocoagulation forceps.

Background technique:

At present, bipolar coagulation forceps are mostly used in relatively delicate operations such as brain surgery, microsurgery, ENT, obstetrics and gynecology, and hand surgery. The safety of bipolar coagulation is now recognized by people, and its scope of use is gradually expanding. Its application method is: two-pole safety current enters the forceps, connects the two clamps through insulating installation, and provides high-frequency electric energy to the body tissue through the two tips of the bipolar, so that the tissue between the two ends of the bipolar is dehydrated and solidified. To achieve the purpose of hemostasis. There are many kinds of bipolar electrocoagulation forceps in the prior art, and its key technology is that two pieces of clamps are installed crosswise. It is also insulated with a polymer separator (plastic, rubber, etc.). The disadvantage is that the cross installation of the two clamps is very weary; the polymer sleeve and the partition are installed separately. In the application, when the two clamps provide high-frequency power to the body tissue, high temperature will be generated, and the sleeve installed separately The tubes and partitions will seep and conduct electricity, causing the polymer material to soften, deform or melt. Due to the large wear and tear, the current bipolar coagulation forceps will be scrapped after several uses, which cannot meet the ideal postoperative effect.

Preferably, the front end of the push rod is formed with a stud, the stud is screwed into the threaded hole of the ceramic guide head, the diameter of the stud is smaller than the diameter of the push rod, and the front end of the push rod leans against the ceramic guide head.

Preferably, several serrated grooves are formed on the opposite end surfaces of the jaws on the pliers head part.

Preferably, the rear end of the connecting rod on the pliers head part is bent to form a stop bar, and the stop bar leans against the rear end surface of the positioning post, and the positioning post is made of insulating material.

The beneficial effect of the present invention is that it changes the clamp structure of the cross structure into the clamp structure of the separation structure, reduces wear and tear, and can ensure good electrode insulation and isolation effect. Compared with the clamp of the cross structure, it effectively increases the clip life.
