[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-7The utility model provides a technical solution: a ligation device capable of retaining an endoscope forceps channel, comprising an endoscope tube 100 and a ligation assembly 200 assembled at the end of the endoscope tube 100, and a wire collector 300 installed at the side of one end of the endoscope tube 100 away from the ligation assembly 200, the ligation assembly 200 comprising a sleeve 210 and a pull wire 220, one end of the pull wire 220 passes through the sleeve 210 and is wound around the outer wall of the sleeve 210 for several turns, and a ligation ring 230 is sleeved on the front of each turn, and the outer wall of the sleeve 210 close to the end of the silicone tube 110 is provided with a ligation ring 230. The coaxial sleeve is provided with a positioning sleeve 240 for fixing the end of the pull wire 220. The other end of the pull wire 220 extends into the silicone tube 110 and passes through the outer wall of the silicone tube 110 and is wound around the wire reel 300. The endoscope tube 100 includes a silicone tube 110 and an endoscope 120. The two sides of the inner wall of the silicone tube 110 are respectively provided with a first through hole 130 and a second through hole 140 for the endoscope 120 and the pull wire 220 to pass through. The first through hole 130 and the second through hole 140 are distributed along the axial direction of the silicone tube 110 and an instrument channel 150 is reserved between the two.

[0032] Based on the above-mentioned structural setting, the ligation device that can retain the endoscopic forceps channel is composed of an endoscope tube 100, a ligation assembly 200 and a wire take-up device 300, wherein the ligation assembly 200 is sleeved on the end of the endoscope tube 100, and the operator can use the ligation assembly 200 to ligate the diseased tissue while observing through the endoscope 120, and the wire take-up device 300 is used to trigger the ligation assembly 200 to launch the ligation ring 230. Specifically, during the working process, one end of the pull wire 220 is wound around the outer wall of the sleeve 210 and is fixed and limited by the positioning sleeve 240. During the winding process of the pull wire 220, taking a ligation ring 230 as an example, the pull wire 220 first passes through the ligation ring 230 and the outer wall of the sleeve 210 along the axial direction of the sleeve 210, and is wrapped around the rear of the ligation ring 230 for one circle, and then continues to perform the same operation on the next ligation ring 230. When the operator pulls the pull wire 220, the ligation ring The pull wire 220 wound around the rear of 230 will move forward, thereby driving the ligation ring 230 to move forward until the ligation ring 230 is released from the sleeve 210, that is, the launching action of the ligation ring 230 is completed, and the pulling action of the pull wire 220 can be completed by the wire take-up device 300. The ligation device that can retain the endoscope forceps channel is provided with a silicone tube 110 with an integrally formed structure and respectively provided with a first through hole 130 and a second through hole 140. Two separate channels for the endoscope 120 and the pull wire 220 to pass through are formed in the silicone tube 110, and at the same time, an instrument channel 150 is reserved between the two. On the one hand, in the silicone tube 110, the endoscope 120, the pull wire 220 and the instrument do not interfere with each other, ensuring the stability and convenience of the use of the ligation device. On the other hand, the wire take-up device 300 is assembled on one side of the outer wall of the endoscope tube 100, away from the endoscope 120 and the instrument operating end, avoiding the phenomenon of mutual entanglement and improving the convenience of use.

[0033] Furthermore, the instrument channel 150 is a circular through-hole structure, and the instrument channel 150 is distributed along the axial direction of the silicone tube 110. The instrument channel 150 is used for clamping tissue biopsy, removing foreign matter, etc. during surgery. In use, the main function of the instrument channel 150 is to provide a channel through which the operator can insert various forceps, grabbers and other tools. Specifically, the channel is arranged between the first through-hole 130 and the second through-hole 140, and is not limited to the following. Figure 3 The cavity structure shown in FIG. Figure 6 The circular through-hole structure shown.

[0034] Furthermore, an annular protrusion 160 integrally connected to the silicone tube 110 is coaxially disposed on the outer wall of one end thereof, and a clamping groove 250 adapted to the annular protrusion 160 is disposed on the inner wall of the sleeve 210. The mutually adapted annular protrusion 160 and the clamping groove 250 can realize convenient disassembly and assembly between the sleeve 210 and the end of the silicone tube 110, and the ligation assembly 200 can be used as a separate device, and in actual use, it can be assembled on the end of the silicone tube 110 according to needs, thereby improving the flexibility of use.

[0035] Furthermore, a sleeve 180 extending into the second through hole 140 is inserted in an inclined direction on the mounting seat 170, and a connecting tube 310 is vertically installed at the bottom of the wire take-up device 300, and one end of the connecting tube 310 away from the wire take-up device 300 is threadedly connected with the sleeve 180. Among them, the wire take-up device 300 is mainly used for winding and triggering the pulling of the wire 220. One end of the wire 220 extends in the second through hole 140 and passes through the sleeve 180 and the connecting tube 310 in sequence, and is finally wound on the wire take-up device 300. The sleeve 180 and the connecting tube 310 realize the separate extraction of the wire 220 in the silicone tube 110, and avoid the wire 220 from contacting and winding with the endoscope 120 circuit and equipment, thereby optimizing the winding operation.

[0036] Furthermore, it also includes an auxiliary tool 400 for installing and pulling the pull wire 220 , and the auxiliary tool 400 is composed of a silicone rope 410 and a hook 420 fixedly connected to the end of the silicone rope 410 . Among them, the auxiliary tool 400 is used for the traction and installation operation of the pull wire 220. Specifically, the operator first pulls the silicone rope 410, inserts the hook 420 into the connecting tube 310, and passes through the sleeve 180 and the second through hole 140 in sequence to lead it out from the end of the silicone tube 110. At this time, the operator ties the end of the pull wire 220 led out of the ligation assembly 200 after the installation of the ligation ring 230 to the hook 420, and then the operator pulls the silicone rope 410 by external pulling until the hook 420 is pulled out. The operator first clamps the ligation assembly 200 on the end of the endoscope tube 100, and then unties the pull wire 220 from the hook 420 and ties it to the wire take-up device 300. The operator uses the wire take-up device 300 to wind up the pull wire 220 until the pull wire 220 is in a tensioned state, that is, the installation operation of the pull wire 220 is completed.
