Abstract

The invention belongs to the technical field of medical instruments, and relates to instruments used for sealing blood vessels of a human body in a surgical operation, in particular to a sealer structure and a split type preassembled sealing clamp structure. The sealer structure comprise an upper fitting body and a lower fitting body which are matched with each other for use, the lower fitting body comprises a lower fitting body strip, and buckling grooves are respectively formed at two ends of the lower fitting body strip in the length direction; lower anti-skid teeth are arranged on the sealed surface of the lower fitting body strip; the upper fitting body comprises an upper fitting body strip, two ends of the upper fitting body strip are respectively provided with a buckling thorn, the inner side of each buckling thorn is provided with an integrally connected inverted buckle, the sealed surface of the upper fitting body strip is provided with upper anti-skid teeth, and the inverted buckles are matched with the buckling grooves, so that the upper fitting body is connected with the lower fitting body; and upper fixing columns are arranged at the two sides of the two ends of the surface of the upper fitting body in the length direction respectively, and lower fixing columns are arranged at the two sides of the two ends of the surface of the lower fitting body in the length direction respectively. The structure can conveniently and quickly seal a human body small pipeline, and the product is convenient to produce.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and relates to an instrument for sealing human blood vessels and pipeline tissues in surgical operations, in particular to a sealer structure and a split-type pre-installed seal forceps structure. Background technique [0002] Due to the characteristics of short-term need and long-term uselessness, it is best to use absorbable instruments to seal blood vessels or pipeline tissues during clinical operations, which can meet short-term needs and avoid hidden dangers caused by foreign bodies staying in the body for a long time. Such a device must have five major properties of biocompatibility, puncture, closure, absorbability, and strength maintenance in order to fully meet clinical needs. Due to the performance limitations of bioabsorbable materials, it is difficult to make absorbable closure devices into a simple and effective structure that is as rigid and flexible as non-absorbable "V...
