AI Technical Summary

Technical Problem

The existing laparoscopic tumor spin-section technology has safety risks, especially the risk of tumor fragment dispersion, and requires cooperation among multiple people, which increases the complexity of the surgery and human resource occupation.

Method used

An integrated abdominal tumor sealing and rotary cutting equipment based on pneumatic control is designed, using airbag bags to wrap the tumor, combining grasping forceps and rotating tool tubes to achieve closed cutting and removal of tumors through the pneumatic system, reducing manpower demand and the number of operating holes.

Benefits of technology

The tumor spin-section surgery was achieved in a single person, which reduced the risk of tumor dissemination, improved the safety and efficiency of the surgery, and reduced the number of auxiliary personnel and operating holes.

Abstract

The invention relates to the technical field of medical operation equipment, in particular to integrated abdominal tumor closed rotary cutting equipment based on pneumatic control and a rotary cutting method thereof.The integrated abdominal tumor closed rotary cutting equipment comprises a shell, and a sleeve is arranged at the right end of the shell; the air bag is arranged at the right end of the sleeve and comprises a fixing ring connected with the sleeve, an air channel fixed to the fixing ring and bag cloth, and an elastic rubber strip is fixed to the outer side of an opening in the right end of the air bag; the rotatable knife tube is arranged in the shell and extends into the sleeve, and a rotating assembly for driving the shell to rotate is arranged in the shell; the air inflation assembly is arranged in the shell and used for inflating the air bag; and the clamping jaw part of the grasping forceps can extend into the sleeve from one end of the shell and penetrate through the air bag to extend into the abdominal cavity of the patient. One person can independently complete the whole process from hermetically wrapping the tumor to taking out the air bag and the residual tumor, and the rotary cutting starting and stopping time and the air bag pressure relief node are automatically controlled, so that more efficient and safer laparoscopic surgery can be completed with less manpower.
