Medical six-degree-of-freedom automatic adjusting manipulator grinding and clamping device for surgical operation

Abstract

The invention relates to a medical six-degree-of-freedom automatic adjusting manipulator grinding and clamping device for surgical operation, which is high in control precision and can realize skull surgical operation at any pose and avoid the mechanical injury to brain tissues. The medical six-degree-of-freedom automatic adjusting manipulator grinding and clamping device comprises a base; a revolving table is installed on the base through a motor I and is connected with a hydraulic rod I through a motor II; the hydraulic rod I is connected with a hydraulic rod II; the front end of the hydraulic rod II is connected with a hollow shaft through a motor VIII; a motor III is installed at the tail end of the hollow shaft, and a main shaft of the motor III passes through the hollow shaft and is connected with a revolving shaft; the revolving shaft is connected with a T-shaped connecting rod through a motor IV; the T-shaped connecting rod is connected with a connecting rod II; the connecting rod II is connected with a connecting rod I; a hydraulic device is arranged at the end part of the connecting rod I, and a strain foil is arranged at the bottom of the connecting rod I and is connected with the hydraulic device through a feedback adjusting device; a transverse and longitudinal movement device is arranged at the front end of the connecting rod I; a clamping device is installed on the longitudinal movement device and consists of a catching device I and a catching device II, and a motor V for driving is arranged between the catching device I and the catching device II.

Description

technical field [0001] The invention relates to a medical device, in particular to a grinding and clamping device for a six-degree-of-freedom automatic adjustment mechanical arm for medical surgery. Background technique [0002] Bone grinding is a procedure in which neurosurgeons often endoscopically enlarge the inside of the nose, through the nostrils as passages, in patients with cancers of the skull base. This minimally invasive technique provides a direct access to skull base tumors without disfiguring conditions. Finding and removing diseased tumors during brain tumor resection requires extensive grinding of the bone surrounding the optic nerve, cavernous sinus, and branches of the trigeminal nerve to identify and protect these major nerves. But grinding the bone generates heat and can damage nerves. Moreover, such thermal damage can lead to blindness and loss of facial muscle control, which is a concern for neurosurgeons due to lack of knowledge of heat transfer to n...

Problems solved by technology

The manual micromanipulator widely used in cranial surgery currently only has two degrees of freedom of rotation and clamping, and often requires the operator to perform a large number of auxiliary actions to achieve a certain working space, which increases the difficulty of surgical operations and reduces surgical efficiency. , it will also bring unnecessary additional damage to the patient
