Sterile isolation device for laparoscopic surgery robot and laparoscopic surgery robot thereof

Abstract

The invention provides a sterile isolation device for a laparoscopic surgical robot and the laparoscopic surgical robot thereof, and relates to the field of laparoscopic surgical robots, the sterile isolation device comprises a robotic arm, an execution arm, a non-elastic transparent film, a connector and an instrument, the execution arm is connected to the robotic arm, the instrument is connected to the execution arm through the connector, and the non-elastic transparent film is arranged on the non-elastic transparent film. And one end of the inelastic transparent film is sleeved on the mechanical arm, and the other end of the inelastic transparent film is adhered to the connector, so that the mechanical arm, the execution arm and part of the connector are sleeved in the inelastic transparent film. Rapid installation and replacement of all parts are achieved through the quick-change switch, and usability is achieved; absolute sealing is achieved through the inelastic transparent film, and safety is achieved; the non-elastic transparent film is common in material, easy to manufacture and economical, on one hand, interference of an elastic body on the motor is avoided, on the other hand, absolute sterile isolation is achieved, and the safety of an operation can be greatly improved.

Description

technical field [0001] The present invention relates to the field of laparoscopic surgical robots in the field of medical instruments, in particular, to an absolutely sterile isolation device for a laparoscopic surgical robot and a laparoscopic surgical robot therefor. Background technique [0002] Existing technical solutions of sterile isolation devices for laparoscopic surgical robots can be divided into two categories: 1. Labyrinth semi-sealing solution; 2. Scalable flexible elastomer sealing solution. The labyrinth semi-sealing scheme obviously cannot achieve the effect of absolute sealing, and its safety is low; its motor output does not have effective aseptic isolation measures, only a part of the aseptic boundary can be formed, and the safety is also low. . The retractable flexible elastomer sealing scheme relies on a flexible elastomer to transmit the driving force. Since each driving device is connected to the same elastic body, the elastic body will cause interfe...

AI Technical Summary

Problems solved by technology

In the labyrinth semi-sealed scheme, the airtightness of the device obviously cannot achieve the effect of absolute sealing, and the safety is low; there is no effective aseptic isolation measure at the output end of the motor, only a part of the aseptic boundary can be formed, and the safety is also low

The scalable flexible elastic body sealing scheme relies on a flexible elastic body to transmit the driving force. Since each driving device is connected to the same elastic body, the elastic body will cause interference between different driving forces, which will increase the load on the driving motor.
