Collaborative awareness laparoscopic surgery constant-pressure support system and implementation method thereof

Abstract

The invention relates to a collaborative awareness laparoscopic surgery constant-pressure support system and an implementation method thereof, on the basis of an ultrasonic knife with an attraction function, real-time pressure of an abdominal cavity is automatically aware, the size of an air inlet valve is dynamically adjusted according to a standard set value, dynamic air supply is realized, andabdominal cavity pressure balance in the surgery process is achieved; a historical database is used for calculating and recording the optimal air pressure of patients with different disease types (stomach cancer and colorectal cancer), disease periods, genders, ages, body conditions and weights (BMI) in the actual operation process, the air pressure actually needed by the operation is accurately set, the system has a guiding significance more generally, and doctors with less operation experience are helped to set the reasonable abdominal cavity air pressure; a big data clustering analysis technology is applied to continuously optimize the data, so that a better effect is achieved; influence on the existing operation system is small, and the compatibility and the usability are high; the laparoscopic surgery efficiency and effect can be improved, the pain and postoperative complications of the patient are reduced, and the operation burden of the doctor is relieved.

Description

technical field [0001] The invention relates to an air pressure control technology for laparoscopic surgery, in particular to a collaborative sensing constant pressure support system for laparoscopic surgery and its implementation method. Background technique [0002] In China, the morbidity and mortality of digestive tract tumors such as colorectal cancer and gastric cancer rank among the top, seriously affecting the health of the people. With the development of minimally invasive technology, especially the continuous improvement of high-definition camera systems and laparoscopic instruments, laparoscopic surgery for colorectal cancer and gastric cancer has become feasible, which can reduce the impact of surgery on the patient's immune system and general condition, and is more in line with rapid surgery. Rehabilitation surgery concept, conducive to the recovery of patients. Laparoscopic surgery is a minimally invasive surgical technique for the treatment of abdominal disea...

Problems solved by technology

However, the current pneumoperitoneum pressure of abdominal carbon dioxide is set by doctors based on experience, generally at 9-12 atmospheres. There are still many problems in the control of abdominal air pressure in this type of laparoscopic surgery, including: (1) individual patients are not considered Some patients can bear this air pressure; but other patients are prone to complications such as acidosis due to the incorporation of carbon dioxide into the blood.

(2) During the operation, the liquid and gas produced by the vaporized human tissue of the ultrasonic scalpel need to be removed in time. During the process of suctioning and extracting these medical wastes, the pressure in the abdominal cavity will be reduced, and the existing gas replenishing device cannot be balanced and effective. To ensure the stability of abdominal air pressure, if the air pressure is low, it will affect the progress of the operation, if it is high, it may cause acidosis and other complications

(3) There is no precise digital air pressure regulation mechanism
