Repeating clip applier capable of being provided with tissue clip bin

Abstract

The invention provides a repeating clip applier capable of being provided with a tissue clip bin. The repeating clip applier capable of being provided with a tissue clip bin comprises a handle assembly, a tissue clip bin assembly, a propulsion adjusting assembly, a clip pushing assembly and a clip applying assembly. The tissue clip bin assembly comprises a tissue clip bin (20), a pressing spring (21), a spring cover plate (22), a plurality of tissue clips (23) and a tissue clamp bin cover plate (24) are arranged in the tissue clamp bin from top to bottom, wherein the tissue clips are stacked from top to bottom and in a natural stretching state. A tissue clip bin is needed to be loaded according to operation requirements before an operation, a fixed number of the tissue clips are arranged in each tissue clip bin, the tissue clips in the tissue clip bin are in a natural telescopic state, after the tissue clips in the tissue clip bin pushed into a forceps rod to be stored, the tissue clips can enter an endoscope channel, and repeating clip of the tissue clips in a process of closing the tissue or the blood vessel is realized.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a continuous clip applier capable of installing a tissue clip chamber. Background technique [0002] Tissue or blood vessel closure is a common operation in surgical operations, and hemostatic forceps, electrocoagulation forceps, sutures or tissue clips are usually used to close tissues or blood vessels to prevent bleeding. With the development of minimally invasive surgery, its advantages of less trauma and faster recovery are accepted by more and more doctors and patients. However, minimally invasive surgery also brings certain difficulties to the operator due to the small space and narrow field of view. Tissue closure clips are mainly used in surgical operations to clamp blood vessels to stop bleeding or to close tubular tissues, including small and medium arteries and veins, bile ducts, etc. The number of ligation clips used in each operation ranges from 2 to 15.

Problems solved by technology

[0005] The clip applicator described in the patent CN101601596A can realize continuous firing and has clip application function, but it is a one-time use medical device, and 10 to 20 titanium clips are installed in the clip applier mechanism at one time, but in actual operation It may not be necessary to use such a large number of ligation clips. If they are not used up, they will be thrown away together with the clip applicator, which obviously causes a waste of resources. In addition, the titanium clips used for ligation are not elastic, easy to conduct electricity, and cannot be absorbed by the human body, which will affect postoperative procedures. Imaging examinations such as CT or MRI

[0006] The preloaded tissue clips in the clip applier described in the patent CN105997183A are in a compressed state during production. If a long time has passed between production and use, the tissue clips are always in a compressed state, which may cause tissue clips to collapse. Failure, if there is a tissue clip failure during the operation, it will affect the operation process and patient safety
