Abstract

The compression method auxiliary device for the pancreatic surgery comprises a deformable transparent compression panel, wherein a hollowed-out structure comprising a pancreatic duct channel, a needle penetration channel and a suture notch is arranged in the middle of the panel, and a fixing buckle used for being connected with each other to adjust the curvature of the panel is arranged. When the device is used, the panel is matched with the pancreas section form through the connecting and fixing buckle, the device is attached to the compression section to stop bleeding, the pancreas tube is exposed through fine adjustment observation of tissue dynamic response, after the pancreas tube is led out to the pancreas tube channel, the needle is guided to perform accurate full-layer sewing through the needle penetrating channel, the sewing thread is moved to the pancreas tube channel through the sewing thread opening after sewing, multi-point reinforcement sewing can be performed, and finally the fixing buckle is released to enable the panel to be safely removed after the panel is restored to an open state. Realize the synchronous completion of harmless hemostasis by compression in the art, the pancreas tube is revealed to developments and accurate guide is sewed up, effectively reduces postoperative pancreas fistula and hemorrhage risk, promotes operation security and efficiency.

Description

Compression method auxiliary device for pancreatic surgery and application method thereof Technical Field The invention relates to the technical field of medical equipment, in particular to a compression method auxiliary device for pancreatic surgery and a use method thereof. Background Pancreatic surgery, such as pancreatodectomy, pancreatectomy, etc., is an important means for treating pancreatic tumors, chronic pancreatitis, etc. Such procedures often require dissociation of the pancreas and delicate manipulation of the remaining pancreatic sections, one of the most critical steps being the identification, visualization and suturing of the pancreatic ducts. Pancreatic duct is the main discharge channel of pancreas exocrine liquid, if the pancreas duct is handled inappropriately after the operation, leads to anastomotic leakage or suture inadequately, will cause postoperative pancreas fistula, hemorrhage, serious complications such as peritoneal infection, show influence patient's prognosis, even endanger life. Pancreas parenchyma, arteriovenous blood vessels and pancreas tubes are simultaneously arranged on the section of pancreas. Due to individual anatomical differences, the position, trend and pipe diameter size of pancreatic ducts vary greatly. Especially when the pancreas tissue is soft in texture, has oedema or inflammation on its cross-section, it is visually difficult to distinguish the tiny pancreatic ducts (sometimes only 1-2 mm) from the surrounding tissue or small blood vessels, and the pancreas cross-section often has continuous bleeding and pancreatic juice exudation after separation, which can rapidly obscure the operative field, interfering with the surgeon's view. To obtain a clear field of view, a method currently in common use is to use electrocoagulation (electrotome) to extensively stop bleeding from the section. However, the thermal coagulation hemostasis method has obvious disadvantages that firstly, the tissue eschar generated by the electric coagulation can directly cover or damage the tiny pancreatic duct so as to make the pancreatic duct difficult to find, secondly, the thermal effect can cause tissue degeneration around the opening of the pancreatic duct to influence the firmness of subsequent suturing, and even if the pancreatic duct is successfully found, the position of the pancreatic duct is deep, the surrounding tissue is fragile, and the section of the pancreatic duct can still bleed, so that the whole-layer and accurate suturing of the pancreatic duct wall is challenged. Traditional instrument traction or compression modes often cannot provide a channel which is convenient for accurate puncture and lead wire of a suture needle while stably exposing pancreatic ducts. Disclosure of Invention In order to overcome the above-mentioned drawbacks of the prior art, an object of the present invention is to provide a compression aid for pancreatic surgery and a method of using the same.
