[0028] Please refer to Figs. 1-3 , a perianal surgery pulling paste is shown, which comprises a set of left-right symmetrical pulling assemblies 1. Each pulling assembly 1 has a paste 101 for closely attaching to the skin surface of the patient's buttocks during perianal surgery. The paste 101 is composed of a release paper layer 101a, a sticky layer 101b, an intermediate layer 101c, a reinforcing layer 101d and an outer cover layer 101e.

[0029] The release paper layer 101a covers the bottom surface of the sticky layer 101b, which effectively prevents the sticky layer 101b from being contaminated by the outside world or losing adhesion due to accidental contact, ensuring that it can be well attached to the skin during use.

[0030] The sticky layer 101b is made of acrylate adhesive material. This material has excellent biocompatibility and can adhere closely to human skin. At the same time, when it is peeled off from the skin after the operation, it causes minimal irritation to the skin, reducing the probability of adverse reactions of the patient's skin after the operation. What is particularly important is that the sticky layer 101b can be conveniently separated from the intermediate layer 101c. This feature makes it possible to put the pulling paste into use again after a single operation by replacing only the sticky layer 101b, which not only saves resources but also reduces the cost of use, while ensuring the reliability of each use.

[0031] The intermediate layer 101c is made of polyurethane material and is firmly connected with the adhesive layer 101b and the reinforcing layer 101d by adhesive means. On the one hand, the intermediate layer 101c can effectively buffer external pressure, avoiding the discomfort or damage caused by the direct action of pressure on the patient's skin; on the other hand, it enhances the overall structural strength of the adhesive member 101, making it less likely to deform or be damaged when subjected to pulling force, ensuring the stability and reliability of the pulling process.

[0032] The reinforcing layer 101d is made of soft rubber material, with a higher hardness than the adhesive layer 101b and the intermediate layer 101c, and is firmly fixed with the outer cover layer 101e. The reinforcing layer 101d provides a solid support frame for the adhesive member 101, ensuring that the adhesive member 101 can be stably attached to the patient's skin during the pulling operation, and will not be displaced, deformed or fall off due to the action of pulling force.

[0033] The outer cover layer 101e is made of nylon material, which has good wear resistance and flexibility, effectively resisting the erosion and damage of external environmental factors on the internal structure, prolonging the overall service life of the traction tape and ensuring its good performance state during repeated use.

[0034] The outer cover layer 101e is provided with three traction bands 102 on the side surface away from the reinforcing layer 101d, of which the upper and lower traction bands mainly serve as auxiliary traction. The traction band 102 is made of flat rubber band material, which gives the traction band 102 excellent elasticity and stretchability, making it perform well in performance adaptability under different traction force requirements. During the pulling process, it can not only provide sufficient pulling force to effectively expose the surgical field, but also adjust its length in time according to the elasticity change of the tissue, avoiding damage to the tissue caused by excessive pulling. Each traction band 102 is fixedly connected with a connecting patch 103 at one end close to the outer cover layer 101e, and the connecting patch 103 and the outer cover layer 101e are connected and separated conveniently by magic tape. This connection method provides convenience for adjusting the angle and position of the traction band 102 during the operation, and the doctor can quickly and flexibly change the pulling direction and force according to the actual needs of the operation, so as to accurately control the exposure degree of the surgical field and improve the flexibility and accuracy of the operation. During the operation preparation, the upper and lower traction bands 102 can be buckled and fastened on the fixed rod pre-set around the operating table to realize the pulling action.

[0035] The traction assembly 1 further comprises an air bag 104, which is fixedly connected to one end of one of the three traction belts 102 near the side of the traction belt 102. The two air bags 104 on the two traction assemblies 1 are in communication with an external foot-operated air pump through air pipes. By inflating and deflating the air bag 104 with the foot-operated air pump, the volume and internal pressure of the air bag 104 can be accurately controlled, thereby realizing precise adjustment of the traction force of the perianal tissue. During the preparation stage of the operation, the side of the air bag 104 near the traction belt 102 is connected to the external fixed rod by buckling, and the traction belt 102 and the air bag 104 are fixedly connected to the side away from the fixed rod. In this way.

[0036] Notches are formed on the release paper layer 101a, the adhesive layer 101b, the intermediate layer 101c, and the reinforcing layer 101d at the same positions. These notches play an important role in the operation process. When liquid such as blood or exudate is produced in the surgical area, the liquid can be smoothly discharged through these notches, avoiding accumulation in the surgical site, thereby maintaining the clarity and cleanliness of the surgical field at all times, providing convenient conditions for the operation of the surgeon, and also reducing the soaking and irritation of the liquid to the tissue, which is beneficial to the rapid recovery of the patient after the operation.

[0037] Working principle:

[0038] Before the operation, the medical staff first slowly tears the release paper layer 101a of the traction paste from the adhesive layer 101b, paying attention to keep the adhesive layer 101b clean. Then, according to the site requirements of the perianal operation, the adhesive member 101 is accurately adhered to the skin of the patient's buttocks, ensuring that the adhesive layer 101b is tightly attached to the skin without wrinkles or air bubbles. After adhering, the adhesive member 101 can be pressed appropriately to enhance the adhesion effect. Next, the upper and lower traction belts 102 are pulled tight and buckled on the pre-set fixed rod, the direction and force of traction are adjusted, and at the same time, the connection of the intermediate traction belt 102 and the air bag 104 and the magic tape connection of the connection paste 103 and the outer cover 101e are checked.

[0039] After the operation begins, the traction is performed using a foot-operated air pump, and the doctor can inflate the air bag 104 through the foot-operated air pump according to the need of the operation field of view. As the air bag 104 is inflated, the intermediate traction belt 102 connected thereto is stretched outward, and together with the upper and lower traction belts 102, the perianal tissue is pulled to the two sides, and the operation field of view is fully exposed. During the traction, the doctor can adjust the inflation amount of the air bag 104 at any time through the foot-operated air pump, and accurately control the traction strength. If it is necessary to adjust the traction angle or strength, the connection between the connection sticker 103 and the outer cover 101e can be unfastened through the magic sticker, the position of the traction belt 102 is adjusted, and then it is re-fixed. And the buckling and lacing traction of the upper and lower traction belts 102 can continue to maintain the traction state required by the operation, and ensure the smooth progress of the operation. At the same time, the liquid in the operation can be smoothly discharged through the slot on the release paper layer 101a, the adhesive layer 101b, the intermediate layer 101c and the reinforcing layer 101d.

[0040] After the operation is completed, the gas in the air bag 104 is slowly released, so that the traction belt 102 returns to a relaxed state. Then, the adhesive member 101 is carefully torn off from the skin of the patient's buttocks. Due to the characteristics of the adhesive layer 101b, the damage to the skin can be reduced. Finally, the used traction sticker is treated according to the medical waste treatment regulations, and the operation instruments and the operating table are cleaned and disinfected, so as to prepare for the next operation.
