Problems solved by technology

Looking at these surgical tools for surgical robots, the development trend is from traditional rod-driven, few-degree-of-freedom tools to wire-driven, multi-degree-of-freedom surgical tools. However, in every set of surgical tools that have been developed, surgical scissors There is one type and the tool tip is not replaceable
However, surgical scissors of different types and sizes are required to complete different surgical operations, which requires the use of multiple sets of tools, which not only reduces surgical efficiency, but also greatly increases the cost of surgical equipment
In addition, since there is only one type of surgical scissors for each set of tools, it is easy to cause the bluntness of the surgical scissors, and since the front end of the surgical scissors cannot be replaced, once the surgical scissors are scrapped due to failure, the entire set of surgical tools needs to be replaced
Obviously, this causes a waste of equipment resources and increases the cost of medical equipment

Abstract

The invention discloses surgical scissors for a surgical robot, comprising two scissor blades in the same structure. Either scissor blade comprises a surgical scissor shank and a surgical scissor blade, wherein the two surgical scissor shanks are connected through a shaft, the bottom wall of the surgical scissor blade is connected with a reverse-concave clamping spring, a protrusion is arranged at the bottom of either outer side wall of the reverse-concave clamping spring, the upper part of the surgical scissor shank is provided with a concave fixed block, a socket is arranged at the dent of either inner side wall of a groove of the concave fixed block, the reverse-concave clamping spring is in a shape matched with the shape of the groove of the concave fixed block so that the reverse-concave clamping spring can be inserted in the groove, and the two protrusions of the reverse-concave clamping spring are respectively inserted in the groove to be clamped and matched. The invention has the advantages that the tool front end of the surgical scissors can be replaced with different types and different sizes aiming at different surgical parts and different surgical operations so as to smoothly finish operations.

Description

Technical field [0001] The invention relates to the technical field of medical equipment, and is a surgical scissors with multiple degrees of freedom and a replaceable front end of a surgical robot. Background technique [0002] Minimally invasive surgical robot surgical tools affect and determine the design of the entire robotic system. The performance level of surgical tools is one of the key factors in the performance of the entire surgical robot system. Among them, surgical scissors occupy a pivotal position in the entire set of surgical tools. In minimally invasive surgery, it is necessary to complete the removal of diseased tissues and even the complicated suture and knotting operations without the participation of surgical scissors. [0003] In the process of minimally invasive surgery, for different surgical sites and different surgical operations, surgical tools of different types and sizes need to be replaced in time to complete the operation smoothly. At present intern...
