Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment and relates to bipolar electrocoagulation forceps, in particular to a series of directional insulating bipolar electrocoagulation forceps. Background Art

[0002] Bipolar electrocoagulation forceps is an important tool for hemostasis during surgical operations. It is mainly composed of an electrode support and a forceps body fixed on the electrode support. In actual surgical operations, bipolar electrocoagulation forceps cannot be used alone, but must be used in conjunction with a bipolar electrocoagulation device. That is, the power cord led out from the end of the electrode support is connected to the output end of the bipolar electrocoagulation device. High-frequency electrical energy is transmitted to the forceps tip of the forceps through the power cord and the forceps blades of the forceps body, and acts on the tissue between the two forceps tips, causing the tissue between the two forceps tips to instantly produce a thermal effect, and promote a series of changes such as tissue inactivation, denaturation, coagulation, carbonization and gasification. In this process, the protein components in the blood also coagulate, thereby achieving the purpose of hemostasis.

[0003] The bipolar electrocoagulation forceps in the prior art, such as the bipolar electrocoagulation forceps disclosed in Chinese patents 201420873493.5 and 201220584116.0, still have some shortcomings. Because the blood vessels and tissues in the human body do not exist independently, when the bipolar electrocoagulation forceps in the prior art are used to stop bleeding, the forceps tips of the bipolar electrocoagulation forceps are conductive all around, and the forceps tips of the bipolar electrocoagulation forceps will more or less cause electrical and thermal damage to the surrounding blood vessels and tissues.
