Abstract

The invention relates to the technical field of medical instruments, in particular to a head body position supporting and fixing device for TIPS, and adopts the technical scheme that the head body position supporting and fixing device for TIPS comprises a headrest, a bracket and a clamping ring, the headrest is provided with a fixing groove used for supporting the head of a patient, and the left side wall of the fixing groove inclines downwards. The support is fixed behind the headrest, at least two tension winders are arranged at the upper end of the support, and pull ropes are wound on the tension winders; the lower end of the clamping ring is open, the clamping ring is used for clamping the lower jaw of a patient, and a flexible liner is arranged on the inner side of the clamping ring; the free end of the pull rope is fixedly connected with the upper side of the clamping ring, and the clamping ring is detachably connected with the headrest. According to the invention, enough distance between the mouth and nose of a patient and the sterile sheet can be ensured in the TIPS operation, and the influence of the sterile sheet on the breathing of the patient is avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a head position support and fixation device for TIPS surgery. Background technique [0002] TIPS surgery, also known as transjugular intrahepatic portocaval stent shunt (transjugular intrahepatic stent portosystemic shunt), is a new interventional radiology therapy for the treatment of portal hypertension and upper gastrointestinal bleeding. It utilizes the principle of surgical shunt and establishes an artificial shunt channel between the hepatic vein and the portal vein in the liver parenchyma through the use of a series of interventional devices, thereby reducing portal pressure and reducing or eliminating the rupture of esophageal varices caused by portal hypertension. Bleeding, ascites and other symptoms. During the operation, the patient's head was turned to the left side. After routine disinfection, the patient's head was completely covered with a sterile sheet, a...
