Hepatic portal blocking band with detachable buckle, timing function and no blocking pincers

Abstract

The invention relates to the technical field of liver surgery and particularly to a hepatic portal blocking band which is detachable, has a timing function and does not need blocking pincers. The blocking band comprises a blocking band body; a fixing male piece and a fixing female piece are arranged at the head end and the tail end of the blocking band body respectively; a plurality of protrudingclamps are integrally formed on the fixing male piece; a plurality of inserting holes are formed in the fixing female piece; the protruding clamps can extend into the inserting holes; and the head endand the tail end of the blocking band body are hot-melted into welding ends. According to the hepatic portal blocking band which is detachable, has a timing function and does not need blocking pincers, the fixing male piece and the fixing female piece are arranged to be striking red, so that a surgeon is reminded to pay attention to aligning and embedding of the ends of the blocking band body, and the surgeon does not need to spend time in finding the two ends of the hepatic portal blocking band and then placing blocking pincers. The two ends of the blocking band are closed, so that an exudate cannot enter the tube during an operation, and the exudate in a conventional blocking band tube can be prevented from being thrown into eyes of the surgeon.

Description

technical field [0001] The invention relates to the technical field of liver surgery, in particular to a hepatic portal blocking belt with a detachable buckle, timing and no need for blocking forceps. Background technique [0002] At present, open liver surgery often requires occlusion of hepatic portal blood flow to reduce bleeding or bleeding in the surgical area. Liver surgery is a very risky operation. Once the liver surgery is started, every second counts. Conventional laparotomy uses a thick rubber tube for the hepatic hilar blocking band. After placement during the operation or when the gap is loosened, the two ends of the blocking band will spread out. It takes time to find and then re-align it when blocking again. The blocking forceps can only be placed at both ends of the blocking band, which delays the operation time. Sometimes when the operation is not smooth, searching for the blocking band in a panic can easily damage the surrounding organs and tissues by mist...

Problems solved by technology

Conventional laparotomy uses a thick rubber tube for the hepatic hilar blocking band. After placement during the operation or when the gap is loosened, the two ends of the blocking band will spread out. It takes time to find and then align them when blocking again. The blocking forceps can only be placed at both ends of the blocking band, which delays the operation time. Sometimes when the operation is not smooth, it is easy to accidentally damage the surrounding organs and tissues by looking for the blocking band in a panic

[0003] Occlusion bands sometimes slip due to intraoperative traction and need to be repositioned, wasting operative time

The two ends of the rubber tube used in the conventional blocking belt are open, and it is easy to flow into the exudate mixed with the patient's blood. medical pollution
