Problems solved by technology

There is very little space for the various operating arms to meet, and many of these existing machines move from a plane parallel to the abdominal cavity, which is very easy to interfere with each other, reducing the speed and effect of the operation
[0008] At the same time, most of the existing surgical instrument installation components achieve multiple degrees of freedom through the composition of the R pair and the P pair. During the operation of the surgical robot, the gravity of the surgical instrument and the end of the component will seriously affect the stability of the surgical instrument.
[0009] Further, the existing surgical instrument is fixed on the fixing device. Usually, the surgical inst

specific Embodiment 1

[0024] This embodiment discloses a surgical instrument installation assembly used in laparoscopic surgery, including:

[0025] Fixing device 2, which is used to install surgical instruments. The fixing device includes a fixed point and a movable point. The surgical instrument includes an execution end that goes deep into the abdominal cavity and a power end installed on the fixing device 2. The power end and There is a long tube structure between the execution ends. In laparoscopic minimally invasive surgery, the long tube structure is to penetrate deep into the incision on the surface of the human body;

[0026] The drive assembly 1 is connected to the surgical robot, the drive assembly is connected through the fixed hinge of the first connecting piece 31 and the fixing device 2 and the movable point of the second connecting piece 32 and the fixing device, and the second connecting piece drives the fixing The device rotates about its fixed point, and the long tubular structur...

Abstract

The invention discloses a surgical instrument locating assembly used in the laparoscopic surgery. A surgical instrument is fixed on a fixing device, and comprises an actuating end extending into the abdominal cavity and a power end mounted on the fixing device (2), wherein a long pipe structure is arranged between the power end and the actuating end, a locating assembly carries out locating on thelong pipe structure, and the locating assembly at least comprises a sleeve (211) fixed on the fixing device and used for passing through of the long pipe structure.

Description

technical field [0001] The present invention relates to laparoscopic surgical instruments. Background technique [0002] Laparoscopic surgery is a newly developed minimally invasive method, and it is an inevitable trend in the development of future surgical methods. With the rapid development of industrial manufacturing technology, the integration of related disciplines has laid a solid foundation for the development of new technologies and methods. Coupled with the increasingly skilled operation of doctors, many open operations in the past have now been replaced by endovascular surgery. Greatly increased surgical options. The traditional method of retroperitoneal laparoscopic surgery is to make three small incisions of 1 cm on the patient's waist, each inserting a tube-shaped working channel called "trocar", and all subsequent operations are performed through these three channels; and then special lengthened surgical instruments are used Complete the same steps as open su...
