Abstract

The application relates to a bipolar electrocoagulation surgical tweezers, which relates to the field of medical devices, including: tweezers, tweezers, and a three-dimensional force sensing component, the three-dimensional force sensing components are arranged between the tweezers and the tweezers; at least one A fixing piece, the fixing piece is used to fix the tweezers and the three-dimensional force sensing assembly; at least one connecting piece, the connecting pieces are all arranged between the three-dimensional force sensing assembly and the tweezers tip, for fixing and Connect the 3D force sensing assembly and the forceps tip. It can realize the measurement of the interaction force between the forceps tip and the brain tissue, provide force feedback for the surgical robot system, reduce the damage to the brain tissue caused by the bipolar electric coagulation surgical forceps during the operation, and quantify the relationship between the bipolar electric coagulation surgical forceps and the tissue. The interaction force between them and the doctor's intraoperative operation experience.

Description

technical field [0001] The present application relates to the field of medical devices, and in particular, to a bipolar electrocoagulation surgical forceps capable of sensing three-dimensional contact force at the end. Background technique [0002] With the development of science and technology and the progress of medical undertakings, the current medical level and medical technology are showing rapid development with each passing day. As one of the important indicators to measure the medical level, medical devices have been developing towards precision, automation and sanitation in recent years. The human brain has a fine tissue, rich in nerves and interlaced blood vessels. Neurosurgery has strict requirements, the operation process is delicate, the manual operation process and learning process are long, the operation field and operation posture are limited in the microscopic environment, and the operation risk is high. Bipolar forceps are used for coagulation and dissect...
