Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an anal retractor. Background Art

[0002] Anal diseases, especially common diseases such as hemorrhoids, anal fistulas, and anal fissures, are common, so many patients need surgery. Full exposure of the anus is the key to a smooth operation. Existing anal retractors are generally composed of medical adhesive tape, plastic pull tabs, and fixed adhesive tapes. The fixed adhesive tapes are connected to the medical adhesive tape through plastic pull tabs. When in use, the medical adhesive tape is pasted on the patient's buttocks, and the adhesive tape is pulled outward and upward and fixed on the bed frame, so that the patient's anus is fully exposed; however, the existing anal retractors have the following problems: the angle of traction of the patient's buttocks is single, corresponding to the position where the adhesive tape is fixed on the bed frame. If there are no multiple corresponding fixed structures on the bed frame, the angle of traction of the patient's buttocks cannot be effectively adjusted. Due to the shape and structure of the buttocks, the single traction angle cannot effectively expose the patient's anus, affecting the surgical field. Therefore, a new type of anal retractor is needed. Utility Model Content

Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0025] See also Figures 1 to 4 The utility model provides an anal retractor, which is characterized by comprising:

[0026] A retractor body 1, which is used to be attached to the buttocks of a patient, wherein a first connecting portion 101 is provided in the middle of the retractor body 1, and a second connecting portion 102 is provided near both ends of the retractor body 1;

[0027] A traction structure 2, wherein the traction structure 2 comprises a traction member 4, a first traction rope 201 and two second traction ropes 202, wherein the traction member 4 comprises a traction plate 401, wherein a limiting member 402 is arranged in the middle of the traction plate 401, wherein a reversing shaft 403 is arranged at positions close to both ends of the traction plate 401, wherein a distance between the two reversing shafts 403 is greater than a distance between the two second connection parts 102, wherein a first end of the first traction rope 201 is connected to the first connection part 101, and a first end of the second traction rope 202 is connected to the second connection part 102;

[0028] The fixing adhesive tape 3 is used to be fixed on the bed frame, the second end of the first traction rope 201 passes through the limiting member 402 and is connected to the fixing adhesive tape 3, and the second end of the second traction rope 202 passes through the reversing shaft 403 and is connected to the fixing adhesive tape 3.

[0029] The utility model provides an anal retractor, which is characterized by comprising: a retractor body 1, a traction structure 2 and a fixed adhesive tape 3. When in use, two anal retractors are generally used together, the retractor body 1 is pasted on the patient's buttocks, and the fixed adhesive tape 3 is pulled outward and upward. During this process, the fixed adhesive tape 3 drives the first traction rope 201 and the two second traction ropes 202 to pull the retractor body 1 to pull the patient's buttocks. The second end of the second traction rope 202 passes through the reversing shaft 403 and the reversing shaft 403. The fixed adhesive tape 3 is connected, and the distance between the two reversing shafts 403 is greater than the distance between the two second connecting parts 102. The two reversing shafts 403 can change the pulling direction of the two traction ropes. Under the action of the two reversing shafts 403, the two second traction ropes 202 will be pulled away from the middle of the retractor body 1. Through the cooperation of the first traction rope 201 and the two second traction ropes 202, the patient's buttocks can be pulled from multiple angles, thereby better exposing the patient's anus and providing a better field of view during surgery.

[0030] In a further implementable embodiment of the present invention, the first side of the retractor body 1 is convex outward, the second side of the retractor body 1 is concave inward, and the first connecting portion 101 and the second connecting portion 102 are both arranged on the first side of the retractor body 1 .

[0031] In this embodiment, the first side of the retractor body 1 protrudes outward, and the second side of the retractor body 1 is recessed inward, so that the retractor body 1 is semi-circular as a whole. Since the two second traction ropes 202 will pull in the direction away from the middle of the retractor body 1, the first connection part 101 and the second connection part 102 are both arranged on the first side of the retractor body 1, and the second connection part 102 is arranged at a position close to the two ends of the semi-circular retractor body 1. When the two second traction ropes 202 are pulled obliquely, wrinkles at the traction part can be reduced, thereby ensuring that the retractor body 1 can be firmly adhered to the patient's buttocks, avoiding the patient's buttocks from shrinking due to loose adhesion during the operation, thereby affecting the operation.

[0032] In a further implementable embodiment of the present invention, an adhesive layer 103 is provided on the back side of the retractor body 1 .

[0033] In this embodiment, an adhesive layer 103 is provided on the back of the retractor body 1 , and the retractor body 1 is adhered to the buttocks of the patient through the adhesive layer 103 .

The limiting hole 404 is set in the middle of the limiting member 402, and the first traction rope 201 is inserted into the limiting hole 404. By setting the limiting hole 404, the position of the first traction rope 201 can be limited. During the traction process, the first traction rope 201 and the second traction rope 202 are prevented from being entangled together, thereby improving the convenience of use.

[0038] In a further feasible embodiment of the present invention, the reversing shaft 403 is rotatably disposed on the traction plate 401 .

[0039] In this embodiment, the reversing shaft 403 is rotatably arranged on the traction plate 401, so that there is rolling friction between the second traction rope 202 and the reversing shaft 403 during use, thereby reducing the wear of the second traction rope 202, increasing the service life of the second traction rope 202, and avoiding the breakage of the second traction rope 202 during the operation, causing the patient's buttocks to contract and affecting the operation.
