A Multifunctional Surgical Instrument for Minimally Invasive Surgical Robot

Abstract

A multi-functional surgical instrument used for a minimally invasive surgery robot comprises blades and forceps. Each jaw piece of the forceps is composed of an upper part and a lower part, wherein the upper part and the lower part are connected through elastic cylindrical pins, the blades are hinged to the upper parts of the jaw pieces through articulated shafts, reset springs are arranged on the articulated shafts in a sleeved mode, one end of each articulated shaft is exposed through each jaw piece to serve as a button, clamping blocks are arranged on the articulated shafts, clamping grooves are formed in the corresponding positions between the upper parts of the jaw pieces and the clamping blocks of the articulated shafts, the articulated shafts are installed in shaft holes in the blades, limit grooves are formed in the inner sides of the shaft holes and matched with the clamping blocks on the articulated shafts, the clamping blocks are clamped in the limit grooves to form circumferential limit matching between the articulated shafts and the blades, limit blocks are arranged at the corresponding positions between the lower parts of the jaw pieces and the shaft holes in the blades, one ends of the reset springs and the limit blocks are fixed, and the other ends of the reset springs and the articulated shafts are fixed. The circumferential limit between the articulated shafts and the blades is ineffective through pressing the buttons, the blades rotate around the articulated shafts under the action of the reset springs, switching among the forceps function, the blade function and the scissor function is achieved, and surgical time is saved.

Description

technical field [0001] The invention relates to a medical robot device, in particular to a multifunctional surgical instrument for a minimally invasive surgical robot. Background technique [0002] Minimally invasive surgery refers to a surgical operation in which a slender laparoscope and surgical instruments are inserted into the patient's body through a small incision, and the doctor operates with the help of an image monitoring system. [0003] Compared with traditional open surgery, minimally invasive surgery has the advantages of small incision, less bleeding, less scar and faster recovery time. However, there are also many shortcomings. Due to the constraints of the incision on the body surface, the movement of the doctor's hand is opposite to the movement of the end of the surgical instrument during the operation, resulting in uncoordination of the eyes and hands, which greatly reduces the surgical flexibility. In addition, the shaking of the doctor's hand will be a...

Problems solved by technology

Therefore, when replacing surgical instruments, it is inevitable to take them out of the body, thereby prolonging the operation time and reducing the operation efficiency.
