Hemostatic instrument for laparoscopic liver resection

Abstract

The hemostasis instrument comprises a guide rod, a grab handle is installed at one end of the guide rod, a hemostasis pressing block is installed in the guide rod through a shaft rod, and symmetrically-arranged power structures are installed in the guide rod; the power structure comprises an air bag, a baffle, a second pressure sensor and an alarm, the air bag is connected to the surface of the tail end of the hemostasis pressing block, the second pressure sensor is installed in the air bag, the baffle is installed on the inner wall of the guide rod, and the alarm is installed on the surface, close to the guide rod, of the grab handle. And an elastic force detection structure is mounted in the hemostasis pressing block. The power structure is arranged, the baffle is used for blocking the expanded air bag, the air bag can only extend longitudinally, the power structure is simplified, the air conveying amount needed by air bag expansion extrusion can be reduced, and in addition, after the air bag is damaged, the alarm can give out a prompt outwards during air inflation, and a doctor is reminded to replace the air bag in time.

Description

technical field [0001] The invention relates to the technical field of liver hemostats, in particular to a hemostatic device for laparoscopic hepatectomy. Background technique [0002] The liver is the largest solid organ in the human body, with extremely rich blood supply. Hepatectomy is complicated and sometimes difficult. Hemorrhage will occur in different degrees during and after the operation. The amount of bleeding is positively related to the incidence of complications and mortality after surgery Related, therefore, controlling and reducing hemorrhage in hepatectomy is an important measure to reduce the incidence of postoperative complications and surgical mortality. The current methods of hepatectomy include: Blood flow occlusion, whole liver blood flow occlusion, etc.; 2. Mechanical hemostasis methods: such as liver forceps, tourniquet method, etc.; 3. Biochemical hemostasis methods: such as absorbable hemostatic sponge; 4. Physical instrument hemostasis methods: su...

Problems solved by technology

This hemostatic device for hepatobiliary surgery is provided with a liquid storage chamber and a shunt chamber in the hemostatic device. The hemostatic drug in the liquid storage chamber enters the shunt chamber through a connecting tube, and then pushes the push rod to drive the piston to move, and then the hemostatic The medicine is squeezed into the cotton ball through the hose, and then hemostasis is performed on the liver and gallbladder, thereby improving the hemostasis efficiency.” The hemostatic device failed to take into account the elastic force detection of the relevant components after recycling, making the relevant components elastic after recycling. The weakening cannot maintain a tight fit with the device itself, and it is easy to cause blood to contaminate related components during the hemostasis process;
