Description

Technical Field

[0001] The utility model relates to the technical field of electrocoagulation forceps, in particular to a bipolar electrocoagulation forceps. Background Art

[0002] Electrocoagulation forceps are commonly used surgical tools, primarily for hemostasis and tissue removal. They are commonly used in various surgeries, especially minimally invasive and endoscopic procedures. Electrocoagulation forceps transmit a high-frequency current through the forceps, generating an electrothermal effect that heats the forceps and coagulates tissue. This method effectively stops bleeding and removes tissue while reducing the risk of bleeding and tissue damage. During surgery, the surgeon inserts the forceps into the patient and connects them to a power source via an outlet. The surgeon controls the flow of current by switching on and off to achieve the desired hemostasis and tissue removal.

[0003] However, the fixed position of the coagulation forceps on the market results in a relatively limited coagulation range. Furthermore, the electrode connector is exposed and unprotected, which can easily cause a short circuit in the power supply during surgery. To address this, we offer a bipolar coagulation forceps to address these issues. Utility Model Content
