Abstract

The invention discloses a manual puncture device and system for robot-assisted puncture operation, and belongs to the field of minimally invasive surgery medical robots. The problems that existing percutaneous puncture operation depends on experience of doctors, and the puncture needle positioning precision is poor are solved. The manual puncture device comprises a shell, a capacitive grating sensor, a puncture needle adjusting mechanism, guide wheels and a fiber grating sensor. When the device is used, a hand wheel of the puncture needle adjusting mechanism is pushed to move in the length direction of a through hole in the side wall of the shell, so that the feeding depth of a puncture needle fixed to a body is controlled; and the hand wheel of the puncture needle adjusting mechanism is screwed to rotate, so that the angle of the puncture needle fixed on the body is controlled. The manual puncture device and system are mainly applied to puncture operations.

Description

technical field [0001] The invention belongs to the field of minimally invasive surgical medical robots. Background technique [0002] Percutaneous puncture surgery is widely used in drainage, trigeminal nerve thermal coagulation, radiofrequency ablation, tumor biopsy, and radioactive seed implantation. At present, the widely used clinical method is to directly hold the puncture needle and insert the puncture needle by marking the needle entry point on the skin in advance or guided by a planar / non-planar template. It is estimated that the doctor cannot perceive the possible deflection of the puncture needle entering the body, and can only rely on the second CT scan. The overall surgical effect is very dependent on the doctor's experience, and the preliminary preparation is complicated and the accuracy is poor; therefore, the above problems urgently need to be solved. solve. Contents of the invention [0003] The purpose of the present invention is to solve the problem th...
