Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and specifically to an operating system and method for an ERCP surgery robot.

Background Art

[0002] ERCP is a very mature endoscopic minimally invasive surgery for treating pancreaticobiliary diseases, also known as endoscopic retrograde cholangiopancreatography. ERCP can be used for the diagnosis and treatment of diseases such as gallstones, biliary obstruction, cholangitis, bile duct tumors, and pancreatic tumors. During the surgical process, a single duodenal endoscope is inserted into the descending part of the patient's duodenum, a contrast catheter is inserted through the biopsy conduit to the location of the duodenal papilla opening, then a contrast agent is injected, and the specific situation of the pancreaticobiliary tract is observed through an X-ray film to determine whether there is a lesion, and then the corresponding surgery is performed. ERCP surgery has the advantages of small trauma, short surgical time, few complications, and high safety. Such surgery belongs to minimally invasive surgery, with very small surgical trauma, not causing much pain to the patient, and rapid postoperative recovery.

[0003] Currently, all ERCP surgeries in China are completed manually by doctors and their teams. ERCP surgery needs to be completed with the assistance of X-rays, and the surgeon needs to be exposed to X-rays for a long time. During the surgery, the operator needs to wear thick and heavy radiation protection clothing, and the arm part needs to be exposed for operation, so it cannot be protected from radiation. Over a long period, surgical radiation can cause serious radiation damage to the operator.

[0004] Conventional ERCP surgery requires many operators and collaborators, and the already limited operating room becomes somewhat crowded. Doctors and operators must stand for the entire day, resulting in high work intensity, fatigue, and ultimately affecting surgical accuracy and leading to errors. During the surgical process, after inserting the duodenal endoscope into the body, it is necessary to adjust the angle of the guidewire catheter inside the body using a lifting platform. It is difficult for doctors and operators to ensure that their hands do not shake, and sometimes the device inserted into the body may shift after being positioned, making it impossible to accurately adjust the lifting platform. Furthermore, if the lifting platform is adjusted directly, the operator is exposed to X-rays, which can cause injury to the operator.

[0005] A Chinese patent with the previous publication number CN213075919U discloses a novel ERCP surgical instrument table, which belongs to the field of medical technology, and includes a support base, on each of the four corners of the top of the support base several connecting rods are fixedly mounted vertically, a housing is supported and positioned between the several connecting rods, several grooves are formed on the front of the housing, a drawer slide groove is fixedly mounted on the inner wall surface of the several grooves, several storage drawers are slidably mounted on the surface of the drawer slide groove, and universal wheels are fixedly mounted on each of the four corners of the bottom of the support base.

[0006] The inventors believe that conventional tables need to be positioned in the operating room for the doctor to pick up the equipment, making it difficult to reduce the risk of radiation damage to the operator during long-term surgery, and that the problem of the doctor's hands shaking during operation needs to be addressed. [Overview of the project] [Problems that the invention aims to solve]
