Example 1
As shown in figures 1-2, an endoscopic auxiliary nylon rope ligation device comprises
The tail end of the first sheath tube 3 is provided with a first sliding handle 5; a first steel wire 4 penetrates through the first sheath tube 3, the front end of the first steel wire 4 is provided with a snare assembly 10, and the tail part of the first steel wire 4 is connected with the control end of a first sliding handle 5 and used for controlling the snare assembly 10 to tighten or open;
when the snare assembly 10 is used for extracting the polyp, the snare assembly 10 can be controlled to be accurately sleeved at the bottom of the polyp from the head of the polyp due to the rigidity of the electric snare 101.
The first sliding handle 5 is provided with a power input end 6, and the power input end 6 is connected with the first steel wire 4 through a wire. Specifically, after the polyp is ligatured by nylon noose 102, switch on at power input 6, first steel wire 4 circular telegram, and then switch on to electric snare 101, because electric snare 101 adopts the steel wire to make, and electric snare 101 is located the polyp bottom, stimulates first steel wire 4, and control electric snare 101 shrink carries out the electrosection to the polyp bottom.
The snare assembly 10 comprises an electric snare 101, a nylon snare 102 and a ligation ring 103, wherein the electric snare 101 is connected with the first wire 4; the tail end of the nylon rope sling 102 passes through the ligation ring 103; the nylon noose 102 is bound on the electric snare 101 by a water-soluble fiber wire 104.

The water-soluble polyvinyl alcohol fiber is a functional differential fiber, has ideal water-soluble temperature, strength and elongation, has good acid resistance, alkali resistance and dry heat resistance, is tasteless and nontoxic after being dissolved in water, is colorless and transparent in aqueous solution, and can be naturally decomposed in a short time. Specifically, after the water-soluble fiber line 104 contacts water, the water-soluble fiber line can be dissolved and disconnected due to the nature of the water-soluble fiber line, at this time, the nylon noose 102 falls off from the electric snare 101, separation of the nylon noose 102 and the electric snare 101 is realized, and the separated nylon noose 102 is sleeved at the bottom of a polyp.
The tail part of the second sheath tube 7 is provided with a second sliding handle 9; a second steel wire 8 penetrates through the second sheath tube 7, the front end of the second steel wire 8 is bent to form a barb 11, and the tail of the second steel wire 8 is connected with the control end of a second sliding handle 9 and used for pulling back the barb 11; after nylon noose 102 and electricity snare 101 separate, control barb 11 articulates at the end of nylon noose 102, pulls second steel wire 8, because the size of ligature ring 103 is greater than the diameter size of second sheath 7, under the cooperation butt of second sheath 7 and ligature ring 103, can control nylon noose 102 to shrink, ligate the bottom of polyp.
The outer tube 1 is sleeved outside the first sheath tube 3 and the second sheath tube 7 at the same time; the tail end of the outer tube 1 is sleeved with an outer tube handle 2; the outer tube 1 is used for delivering a first sheath 3 and a second sheath 7 to the polyp of the intestinal tract; the outer tube handle 2 is then pulled to release the snare assembly 10.
As shown in fig. 3, the second sliding handle 9 and the first sliding handle 5 are commonly used sliding handles, and specifically, the control handle 5 sequentially includes a connecting section 51, a limiting section 52, a sliding section 53 and a tail section 56 from left to right; the sheath tube is inserted at the front end of the connecting section 51; the sliding section 53 is provided with a sliding groove 55 in a hollow manner, the sliding groove 55 is provided with a sliding block 54 in a sliding manner, and the tail end of the steel wire is connected with the sliding block 54. When the slider 54 is slid, pulling of the wire can be achieved.
The working mode of the device is as follows: pushing the outer tube handle 2 so that the snare assembly 10 is placed in the outer tube 1; the outer tube 1 is inserted endoscopically to the polyp of the intestinal tract; controlling the first sheath 3 to enable the snare assembly 10 to be sleeved at the bottom of the polyp from the head of the polyp; then water is poured into the intestinal tract to dissolve the water-soluble fiber 104, and the nylon rope sleeve 102 is separated from the electric snare 101; the second sheath tube 7 is controlled, the barb 11 is hung at the tail end of the nylon rope sling 102, the second sliding handle 9 pulls the second steel wire 8, and the nylon rope sling 102 is controlled to ligate the polyp at the bottom of the polyp. Then, the power supply is turned on, the electric snare 101 is electrified under the conduction of the first steel wire 4, the second sliding handle 5 pulls the first steel wire 4 to contract, and the electric snare 101 is controlled to cut off polyps. After the resection, the auxiliary device is taken out of the intestinal tract, and then the grasping device is inserted to take out the resected polyp.
The above-mentioned embodiments only express the specific embodiments of the present invention, and the description thereof is specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
