Description

Technical Field

[0001] This utility model belongs to the technical field of anorectal ligation devices, and in particular relates to an easy-to-use anorectal ligation threader. Background Technology

[0002] The ligator is a quick-installation device for elastic coils on manual or automated rectal ligation devices. It simplifies the installation process and improves the efficiency of ligation surgery. During operation, the coil support needs to be aligned with the ligation gun barrel before the coil is pushed onto the suction tube using a pushing device. However, the current design of the ligator and its associated structures, including the alignment and support methods, results in low alignment efficiency during installation. Furthermore, the pusher typically uses a front-end force application method, requiring precise operation from the operator to ensure consistency between the force direction and the movement direction. Otherwise, tilting or jamming may occur, or the pushing process may become sluggish. The front-end force application method also causes the operator's hand to obstruct the front device, affecting visibility and increasing the difficulty of operation, thus impacting efficiency. Utility Model Content

Detailed Implementation

[0023] The present invention will be described in detail below with reference to specific embodiments.

[0024] like Figure 1 As shown, this utility model relates to an easy-to-use anorectal ligation suture device, used in the ligation surgery process. It is connected and assembled with the suction tube 4, nozzle 5, suture puller 6, and other parts or structures at the front end of the ligation device to push the elastic coil 3 to the front end of the suction tube 4, facilitating subsequent ligation operations. Using the suture device of this utility model, the small-diameter elastic coil with a stretch warning can be transferred to the front end of the suction tube simply and efficiently. Compared with the existing suture device structure, it adopts a bottom pushing method, which is more convenient for the operator to grasp, and the force application is simpler and more efficient. During the operation, there is no obstruction to the entire suture device, which can obtain a better field of view, is easy to align and adjust, and effectively improves the efficiency of suture operation.

[0025] like Figure 2 As shown, the basic structure of the easy-to-use anorectal ligation device of this utility model includes a pusher 1, a support cylinder 2, and an elastic coil 3.

[0026] The pusher 1 includes a cylindrical mounting part 10 at the front end and an operating part 11 located on the lower side of the cylindrical mounting part 10;

[0027] like Figure 3 As shown, the inner wall of the front side of the cylindrical mounting part 10 is provided with several arc-shaped limiting grooves 10a that are dug out from front to back and guide strips 10b that protrude from the inner wall to the center; the operating part 11 is located on the lower side of the cylindrical mounting part 10 and extends from front to back. The operating part 11 is provided with a strip-shaped clearance groove 11a in the middle and recessed arc-shaped gripping parts 11b on the left and right sides of the operating part 11.

[0028] like Figure 4 As shown, the outer wall of the support cylinder 2 is provided with an arc-shaped limiting strip 2a that can abut against the arc-shaped limiting groove 10a near the front end, and a guide groove 2b that extends in the front-back direction and is directly opposite to the guide strip 10b. The arc-shaped limiting strip 2a extends vertically, and the front edge of the support cylinder 2 is rolled outward to form an anti-detachment ring 2c. The outer diameter of the anti-detachment ring 2c is larger than the inner diameter of the front end of the cylindrical mounting part 10.

[0029] For ease of use, in this embodiment, multiple sets of arc-shaped limiting strips 2a are arranged from front to back on the outer wall of the support cylinder 2; the elastic coil 3 is sleeved on the front side of the set of arc-shaped limiting strips 2a located at the rear.

[0030] like Figure 5 As shown, the support cylinder 2 is inserted into the cylindrical mounting part 10 from front to back and extends out from the front end of the cylindrical mounting part 10, and the elastic coil 3 is sleeved in the extended area of ​​the support cylinder 2.

[0031] As an optimization solution, to facilitate gripping the pusher and improve the user experience, anti-slip strips 11c extending vertically are evenly provided in the recess of the arc-shaped gripping part 11b.

[0032] Meanwhile, in order to ensure that the support cylinder 2 can move smoothly back and forth, and to prevent problems such as the support cylinder 2 rotating and getting stuck during the pushing process, a design scheme can be adopted in which multiple arc-shaped limiting grooves 10a and guide strips 10b are evenly distributed in a ring array on the inner wall of the cylindrical mounting part 10.

[0033] Furthermore, to facilitate monitoring of the coil status before and after the coil is put into operation and to determine whether the bottom wire end of the coil is effectively installed, the front half of the strip-shaped clearance groove 11a extends downward to form an observation hole 11o.

[0034] When in use, the end of the elastic coil 3 is pulled into the strip-shaped clearance groove 11a.

[0035] Furthermore, to facilitate the connection and alignment of the adsorption tube, a connecting post 2d is provided on the rear side of the support tube 2. The outer edge of the rear end of the support tube 2 extends rearward to form an annular connecting part 2e. The inner wall of the connecting part 2e and the outer wall of the connecting post 2d form an annular connecting groove 2f. In use, the front end of the adsorption tube 4 can be inserted into the connecting groove 2f to achieve docking conveniently and efficiently.

[0036] Specific usage instructions:

[0037] Before use, insert the support cylinder 2 into the cylindrical mounting part 10 from front to back, ensuring that the arc-shaped limiting groove 10a and the arc-shaped limiting strip 2a, and the guide strip 10b and the guide groove 2b are aligned with each other. The arc-shaped limiting groove 10a, the arc-shaped limiting strip 2a, and the anti-detachment ring 2c work together to prevent the support cylinder 2 from rotating and limit its maximum backward displacement. After the rear end of the support cylinder 2 extends out of the cylindrical mounting part 10, the elastic coil 3 is put on the rear section of the support cylinder 2 in advance. By optimizing the position of the arc-shaped limiting strip 2a, the relative position of the elastic coil 3 can be further controlled. After preparation based on the above method, a pre-tightened elastic coil feeder is obtained.

[0038] In practical use, align the feeder with the adsorption tube, pull the pusher 1 backward, and use the rear edge of the cylindrical mounting part 10 to push the elastic coil 3 forward and transfer it from the support cylinder 2 to the adsorption tube.

[0039] Through testing, the method of pinching from the bottom to apply force is more stable and convenient. At the same time, it fully exposes the coil and adsorption tube of the feeder, avoiding the problem of obstructed vision during the operation of existing feeders. This allows the operator to continuously observe whether it is fully in place and whether the elastic coil has been transferred to the adsorption tube, thus improving operating efficiency.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
