Abstract

The invention relates to a pair of bipolar electrocoagulation surgical forceps, which relates to the field of medical instruments, and comprises a forceps piece, forceps tips and a three-dimensional force sensing assembly, wherein the three-dimensional force sensing assembly is arranged between the forceps piece and the forceps tips; at least one fixing piece used for fixing the tweezers pieces and the three-dimensional force sensing assembly; and at least one connecting piece arranged between the three-dimensional force sensing assembly and the forceps tips and used for fixing and connecting the three-dimensional force sensing assembly and the forceps tips. According to the bipolar electrocoagulation surgical forceps, the interaction force between the forceps tips and the brain tissue can be measured, force feedback is provided for a surgical robot system, the damage of the bipolar coagulation surgical forceps to the brain tissue in the surgical process is reduced, and the interaction force between the bipolar coagulation surgical forceps and the tissue and the intraoperative operation experience of doctors are quantified.

Description

technical field [0001] The present application relates to the field of medical devices, in particular to a bipolar electrocoagulation surgical forceps with end three-dimensional contact force sensing capability. Background technique [0002] With the development of science and technology and the advancement of medical care, the current level of medical treatment and medical technology are showing rapid development with each passing day. As one of the important indicators to measure the level of medical treatment, medical devices have been developing towards precision, automation and sanitation in recent years. Human brain tissue is fine, with abundant nerves and interlaced blood vessels. Neurosurgery has strict requirements, and there are clinical difficulties such as delicate surgical operation process, long manual operation and learning process, limited surgical field and operating posture in the microscopic environment, and high surgical risk. Bipolar forceps are used t...
