Embodiment Construction

[0024] Below in conjunction with specific embodiment, and with reference to accompanying drawing, the present invention will be further described:

[0025]As shown in the accompanying drawings, the compact quick-change mechanism of the minimally invasive surgical robot of the present invention includes a right lobe transmission assembly 7-4 at the end of the upper interface, a left lobe transmission assembly 7-3 at the end of the upper interface, and a pitching of the upper interface wrist. The upper interface transmission system composed of the transmission assembly 7-2 and the upper interface rotation transmission assembly 7-1 is composed of the right lobe transmission assembly 10-8 at the end of the lower interface, the left lobe transmission assembly 10-7 at the end of the lower interface, and the pitch transmission of the lower interface wrist The lower interface transmission system composed of the assembly 10-6 and the lower interface rotation transmission assembly 10-5 a...

Abstract

The invention discloses a compact quick-change mechanism of a robot for minimally invasive surgery. The compact quick-change mechanism is composed a quick-change box and a quick-change base, and mainly comprises four groups of transmission mechanisms, a limiting and locking mechanism, a driving system and the like, wherein the connecting part of the quick-change box is connected with the tail end of an instrument with a wrist function through a rotating axis, and the quick-change box can quickly slide along a concave chute of the quick-change base, thereby realizing replacement of surgical instruments; the quick-change box sliding into the quick-change base is limited and fixed by the limiting and locking mechanism installed at the tail end of the quick-change base; the four groups of transmission mechanisms are in similar structures, and finally realize four degrees of freedom of the tail end of the instrument in a wire transmission mode respectively by a servomotor; a transmission steel wire can be fixed and tensioned by a wire fixing wheel assembly in each transmission mechanism; and the driving system is composed of a servomotor and a harmonic speed reducer, and is fixed on the base frame of the quick-change base through threaded connection. The compact quick-change mechanism disclosed by the invention has the advantages of compact structure, light weight, reliable transmission, high quick-change efficiency and the like.

Description

technical field [0001] The invention relates to a quick-change mechanism, in particular to a compact quick-change mechanism for a minimally invasive surgical robot. Background technique [0002] Minimally invasive surgery refers to the use of slender surgical tools to penetrate into the body through tiny incisions on the surface of the human body for surgical operations. It is a cutting-edge technology that combines traditional surgery with high-tech surgical instruments and electronic display systems. [0003] The endoscope used in minimally invasive surgery can reach deep into the surgical site, so that the doctor's hand does not need to enter the body, which greatly reduces the damage to the patient's organs and interferes with the function of the organs, and also shortens the postoperative recovery time. shorten. However, while minimally invasive surgery brings many benefits to patients, it also greatly increases the difficulty of operating medical devices, such as (1) ...
