Detailed Implementation

[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0024] [First Embodiment] Please see Figures 1-8 As shown, this utility model provides an adjustable anal traction device, including two sets of traction mechanisms. The two sets of traction mechanisms are arranged opposite each other on both sides of the anus for reverse traction of the perianal buttock skin. In this embodiment, the traction mechanism includes a tape 1, a traction belt 2, and a winder 3 connected in sequence. The tape 1 includes a waterproof layer 1a, a base fabric layer 1b, an adhesive layer 1c, and a release film 1d arranged in sequence from top to bottom. The traction belt 2 includes a winding belt 2a and at least two branch belts 2b, one end of each branch belt 2b being evenly distributed and connected to the tape 1, such as... Figure 1 As shown, in this embodiment, there are two branch belts 2b, and the entire traction belt 2 has a Y-shaped structure. The other end of each branch belt 2b is connected to one end of the winding belt 2; the winder 3 includes a winding frame 3a, on which a winding shaft 3b for pulling and winding the winding belt 2 is rotatably mounted, and the bottom of the winding frame 3a is provided with a fixator that can be detachably fixed to the bed rail.

[0025] This application addresses preoperative anal traction scenarios by specifically designing an easy-to-use and adjustable traction device. The traction mechanism, consisting of tape 1, traction band 2, and winder 3 connected in sequence, is simple to operate, reducing the complexity of traction operations and optimizing surgical efficiency. The tape has a waterproof layer to prevent peeling or curling due to soaking in disinfectant. The specially designed traction band allows for balanced force application to the tape at multiple points, improving the stability and reliability of the traction process. Preferably, tape 1 is a wide, arc-shaped tape with a width of 2-4 cm, providing an appropriate adhesive area to create a stable adhesive fixation effect on the perianal skin.

[0026] [Second Embodiment] Based on the aforementioned first embodiment, and considering waterproof performance, the tape portion can be optimized. A water-retaining strip 4 is provided on the inner edge of the tape 1. The water-retaining strip 4 is higher than the surface of the tape 1. Before the operation, a large area of ​​the perianal region needs to be disinfected. When a large amount of disinfectant is used, it is easy for it to overflow along the surface of the tape to other areas. The design of the water-retaining strip 4 is to prevent disinfectant droplets on the perianal skin from overflowing onto the tape or even the traction band to a certain extent, and to prevent droplets from seeping into the tape from the side gaps.

[0027] [Third Embodiment] Based on the aforementioned first embodiment, and considering the prevention of misoperation or tape detachment, as a feasible design, two elastic bands 5 are used to connect the two opposing traction mechanisms. The two ends of the elastic bands 5 are respectively fixed to the ends of the two opposing tapes 1. These elastic bands 5 provide an elastic connection between the traction mechanisms on both sides and do not affect the traction operation on both sides during the procedure. However, in case of accidents such as forgetting to attach one side of the tape, or excessive traction pulling the tape off, the elastic bands 5 can prevent the tape from being directly pulled off and falling to the ground, thus providing a certain degree of protection.

[0028] [Fourth Embodiment] Based on the aforementioned first embodiment, and considering the efficient and stable winding operation of the winding tape, such as Figure 7-8 As shown, the winding section is optimized. Flat winding tape requires more material and is less effective than winding rope when wound on a reel. In this embodiment, a fixing ring 6 is provided at the end of the winding tape 2a. The pulling mechanism 3 also includes a pull rope 3c. One end of the pull rope 3c is tied to the fixing ring 6, and the other end is fixed to the winding shaft 3b. When the winding shaft 3b is rotated, the winding tape 3a is wound up by the pull rope 3b. Furthermore, for infection control reasons, the winding tape is for single use only, while the pull rope is contactless throughout the process and can be directly untied from the fixing ring and reused after surgery.

[0029] [Fifth Embodiment] Based on the aforementioned first embodiment, as one design form of the winder, such as Figure 7-8 As shown, the winder 3 is a manual winder. Manual winding allows for more control over the pulling force and degree. A winding handle 3d is also installed on the winding frame 3a. The winding handle 3d is connected to the winding shaft 3b by a gear 3e.

[0030] [Sixth Embodiment] Based on the aforementioned first embodiment, as another design form of the winder, such as Figure 7-8 As shown, the winder 3 is an electric winder. Electric winding is more automated and can further save the physical strength of medical staff. As a conventional technology in this field, the electric winder may also include an electric control box. A motor that is electrically connected to the electric control box is installed on the winding frame 3a. The motor shaft is connected to the winding shaft 3b through a transmission. The electric control box is provided with a tension adjustment knob for controlling the forward or reverse rotation of the motor.

[0031] [Seventh Embodiment] Based on the aforementioned first embodiment, as one design form of the fixation device, such as Figure 7-8 As shown, the bottom of the winding frame 3 is provided with two locking plates 7 for mounting on the bed rail. The locking plates 7 are provided with locking screw holes. The fastener is a locking bolt 8 that fits into the locking screw hole. After the locking plates 7 are mounted on the bed rail, the bed rail can be fastened by turning the locking bolt 8.

[0032] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0033] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.
