Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the drive motor arrangement of the existing surgical instruments increases the drive torque of the joints, making the system prone to vibrations. At the same time, the translational movement of surgical instruments is often driven by nuts and leadscrews, which is not conducive to surgery. Before adjusting the position of surgical instruments

Abstract

The invention relates to an integrated surgical instrument drive device, in particular to an integrated surgical instrument drive device with a decoupling function so as to solve the problems that due to the arrangement mode of a drive motor of an existing surgical instrument, drive torque of joints is increased, a system shakes easily, and meanwhile translational motion of the surgical instrument is generally driven in a nut lead screw mode, which is unbeneficial for adjusting the position of the surgical instrument before an operation. The drive device comprises a power source assembly (A), a decoupling transition assembly (B), a connector assembly (C) and a plurality of winding wires (D). The power source assembly (A), the decoupling transition assembly (B) and the connector assembly (C) are sequentially staggered and stacked in a sliding mode from bottom to top, and connected through the winding wires (D) in a decoupling winding mode. The drive device is used for driving a surgical instrument of a robot surgical micro-instrument.

Description

technical field [0001] The invention relates to an integrated surgical instrument drive device, in particular to an integrated surgical instrument drive device with a decoupling function. Background technique [0002] At present, minimally invasive surgery is a hot spot in medical technology research, and it is the development trend of future surgery, mainly because minimally invasive medicine has many advantages: such as less trauma, shorter hospital stay, faster recovery, and fewer postoperative complications. However, traditional endoscopic surgery has many disadvantages, such as low operation accuracy, small field of view, small degree of freedom of operation, and doctors are prone to fatigue and trembling; with the development of science and technology, robotic medical assistance technology can well solve these problems. Robot-assisted technology can provide a 3D field of view, which is convenient for doctors to operate. Micro medical devices greatly increase the flexib...
