Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to a controllable laparoscopic dripping bipolar coagulation forceps. Background Art

[0002] Bipolar coagulation forceps are instruments used in the electrocoagulation treatment process.

[0003] For example, Chinese Patent CN113057730B, a bipolar electrocoagulation surgical forceps, relates to the field of medical devices, and includes: forceps blades, forceps tips, and a three-dimensional force sensing component. The three-dimensional force sensing component is arranged between the forceps blades and the forceps tips; at least one fixing member for fixing the forceps blades and the three-dimensional force sensing component; and at least one connecting member arranged between the three-dimensional force sensing component and the forceps tips for fixing and connecting the three-dimensional force sensing component and the forceps tips. It can measure the interaction force between the forceps tips and brain tissue, provide force feedback for the surgical robot system, reduce the damage caused by the bipolar electrocoagulation surgical forceps to brain tissue during the operation, and quantify the interaction force between the bipolar electrocoagulation surgical forceps and tissue and the doctor's intraoperative operation experience.

[0004] However, there are two types of bipolar coagulation forceps: pointed tips and flat tips. Among them, the forceps rod and handle are insulated, and the pointed tips and the tail ends are conductive. Traditional bipolar coagulation forceps cannot adapt to laparoscopic conditions during the operation. And when there is blood vessel rupture and bleeding and traditional coagulation forceps are used for hemostasis, it is easy to generate local high temperature, resulting in damage to the surrounding tissues of the surgical field. The generated eschar will further affect the effect of the coagulation forceps and the prognosis.

[0005] Based on this, the present invention designs a controllable laparoscopic dripping bipolar coagulation forceps to solve the above problems. Summary of the Invention
