Novel multipurpose loop ligature device and working principle thereof

Abstract

The invention discloses a novel multipurpose loop ligature device. The novel multipurpose loop ligature device comprises a medical surgery silk thread and a gun body, and further comprises a draft device, an operating device and a tightening device, the medical surgery silk thread is knitted into double single knots to form a tightening coil and a loop ligature coil, the cross part of the tightening coil and the loop ligature coil is a tightening knot, and the overall medical surgery silk thread is in a stress state; the gun body is of a cavity structure, and is provided with a vent hole switch and a negative pressure connector which are communicated with the cavity, the vent hole switch is located on a holding handle of the gun body, the negative pressure connector is located at the lower end of the holding handle of the gun body, the inside of the gun body is fixedly connected with the draft device, and the outside of the gun body is movably connected with the operating device through a U-shaped limiting connecting piece. The medical surgery silk thread is still selected and utilized in a loop ligature material, the materials are totally differently from rubber gasket types of materials (including elastic threads), the situation that silk threads which are adopted in manual ligation reoccurs, and the potential safety hazard that massive haemorrhage occurs at a residual end caused when the rubber gaskets are aged and slip off in advance is avoided.

Description

technical field [0001] The present invention relates to the technical field of medical devices, in particular to a novel multipurpose ligation device and its working principle. Background technique [0002] Ligator technology is an emerging treatment in the medical industry and has been widely used in the medical and health industry. It is mainly divided into apron type ligation device and metal ligation device. Apron ligation devices generally include rubber ferrules and elastic threads, and elastic threads are composed of 98% cotton and 2% elastic bands. Rubber rings are mostly used for anorectal internal hemorrhoid ligation; In gastrointestinal submucosal treatment. At present, there is no silk-like ligation device in the industry, and the present invention creates a new type of ligation device. [0003] Apron-type ligation devices rely on the elasticity of the apron to tighten the base of the hemorrhoid. The disadvantage of this type of invention is that it will inevi...

Problems solved by technology

Its disadvantage is that when only ligation is required, the metal ligation device cannot do it, and it must be removed at the same time

Moreover, electric knife resection will cause greater electrochemical stimulation to the surrounding tissues, causing greater side damage, easy perforation of weak tissues, and fat embolism and even death near the fat tissue.

[0005] The traditional manual ligation is to use the method of manua
