Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an anus exposure belt for anorectal surgery. Background Art

[0002] During anorectal surgery, the anus needs to be exposed to facilitate the doctor's surgical treatment. The simple way to expose the anus is to use disposable tape. When using it, stick a piece of tape on the buttocks on both sides of the anus, and then pull the other ends of the two tapes and stick them to the sides of the operating table.

[0003] Chinese patent publication number CN211155976U discloses a novel simple anal retractor, which uses a traction rope, a spring buckle and a fixing hook. The traction length of this structure is adjustable, but the traction rope used for the convenience of adjustment is prone to the problem of force bias on the adhesive tape. If the adhesive tape is biased, it will cause the adhesive tape to slowly fall off. The setting of the fixing hook is also unreasonable, making it inconvenient to fix it on the operating table.

[0004] Chinese patent publication number CN112451011A discloses an anal exposure belt specially used for anorectal surgery. Both ends of the exposure belt are adhesive structures, which are convenient for fixing to the operating table. The belt with a certain width plays a traction role, and the adhesive is not prone to the problem of force deviation. However, the tightener used for the wide belt of this exposure belt can only be adjusted in one direction, that is, it can only be tightened but not loosened. In this way, if the exposure of the anus is offset, one of the exposure belts cannot be adjusted back, and it is also inconvenient to adjust both belts when the anus exposure is too large. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide an anus exposure belt for anorectal surgery, which overcomes the problems of various defects of existing exposure belts, makes the exposure belt easy to use and firmly adheres, ensures a better exposure state of the anus, and helps improve the quality of surgery.

[0006] The utility model solves the technical problem by adopting a technical solution: an anus exposure belt for anorectal surgery, comprising a belt and an adjuster.

[0007] The strip has glue-coated sections at both ends, and release paper is attached to the outer glue surface of the glue-coated sections;

[0008] The regulator has a cylinder frame with a U-shaped cross section, and support plates are fixed on the left and right side walls of the cylinder frame respectively; the regulator has clamping plates respectively located outside the front wall and the rear wall of the cylinder frame; the clamping plates are swingably arranged on a pin shaft, the pin shaft is perpendicular to the left and right side walls of the cylinder frame, and the pin shaft is supported by the support plates on the left and right side walls;

[0009] The drum frame has an upper opening and a lower opening for extending the strip after the strip near the middle section is folded and closed; the part of the clamping plate located above the pin is a pressing part, and the part located below the pin is a clamping part; the regulator is provided with a spring for pushing the pressing part away from the drum frame, and the clamping part has a plurality of teeth facing the drum frame;

[0010] The strips are passed through the cylinder frame. The pressing parts on the two clamps are pressed to move the two clamps away from each other and then the strips move in the cylinder frame. The pressing parts on the two clamps are released to move the two clamps closer to each other and then the strips are pressed to lock the strips in the cylinder frame.

[0011] Specifically, in order to completely separate the tooth pins from the strips, the tooth pins extend into the drum frame from holes arranged in an array on the drum frame.

[0012] Alternatively, the tooth nails are located below the lower opening of the cylinder frame, and the tooth nails of the two clamping plates are close to each other below the lower opening of the cylinder frame to press the strip.

[0013] Specifically, the spring is V-shaped, the bottom of the spring is an arc-shaped bottom sleeved on the pin shaft, the two arms of the spring are respectively against the clamping plate and the cylinder frame, the clamping plate and the pin shaft have two rotating pairs spaced apart, and the spring is located between the two rotating pairs.

[0014] The beneficial effects of the utility model are as follows: the anus exposure belt for anorectal surgery of the utility model uses an adjuster suitable for bidirectional tightness adjustment of a strip with a certain width, and the two ends of the exposure belt are easy to stick, tighten and relax, and the two ends can be firmly stuck to the patient's buttocks and the operating table respectively, so that the anus has a better exposure state, which is beneficial to improving the quality of the operation. In addition, the strip is only provided with glue sections at both ends, and the width of the entire strip does not change. Several strips can be made into a reel shape, and a single strip can be separated by cutting or setting a tear line. The strip is easy to process and the discarded strips are also easy to collect.

[0020] Now, the present utility model will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0021] Appendix Figure 1 Combined with the appendix Figure 2 As shown, an anal exposure belt for anorectal surgery has a strip 1 and a regulator 2. Both ends of the strip 1 have glue - coated sections 1 - 1, and release paper 1 - 2 is attached to the outer glue surface of the glue - coated sections 1 - 1.

[0022] The regulator 2 has a barrel frame 2 - 1 with a square - shaped cross - section. Moreover, the barrel frame 2 - 1 is a relatively flat square - shaped. Support plates 2 - 2 are respectively fixed on the left and right side walls of the barrel frame 2 - 1, and the support plates 2 - 2 can be fixed on the barrel frame 2 - 1 by gluing or screws. The regulator 2 has clamping plates 2 - 3 located outside the front wall and the rear wall of the barrel frame 2 - 1 respectively. The clamping plates 2 - 3 are swing - arranged on a pin shaft 2 - 4, that is, the clamping plates 2 - 3 are rotatably arranged on the pin shaft 2 - 4. The pin shaft 2 - 4 is perpendicular to the left and right side walls of the barrel frame 2 - 1, and both ends of the pin shaft 2 - 4 are supported by the support plates 2 - 2 on the left and right side walls.

[0023] The barrel frame 2 - 1 has an upper opening into which the nearly middle section of the strip 1 is folded and inserted, and a lower opening through which the strip 1 extends. The part of the clamping plate 2 - 3 above the pin shaft 2 - 4 is a pressing part 2 - 3 - 1, and the part below the pin shaft 2 - 4 is a clamping part 2 - 3 - 2. The regulator 2 is provided with a spring 2 - 5 that pushes the pressing part 2 - 3 - 1 away from the barrel frame 2 - 1. The clamping part 2 - 3 - 2 has a number of tooth nails 2 - 3 - 3 facing the barrel frame 2 - 1.

[0024] The folded - together strip 1 passes through the inside of the barrel frame 2 - 1. When the pressing parts 2 - 3 - 1 on the two clamping plates 2 - 3 are pressed, the tooth nails 2 - 3 - 3 on the two clamping plates 2 - 3 move away from each other, and then the strip moves inside the barrel frame 2 - 1. When the pressing parts 2 - 3 - 1 on the two clamping plates 2 - 3 are released, the tooth nails 2 - 3 - 3 on the two clamping plates 2 - 3 move closer to each other and press the strip 1 to lock the strip 1 inside the barrel frame 2 - 1.

[0025] The tooth nails 2 - 3 - 3 extend into the inside of the barrel frame 2 - 1 through the holes 2 - 1 - 1 arranged on the barrel frame 2 - 1.

[0026] The tooth nails 2 - 3 - 3 are located below the lower opening of the barrel frame 2 - 1. The tooth nails 2 - 3 - 3 on the two clamping plates 2 - 3 move closer to each other below the lower opening of the barrel frame 2 - 1 and press the strip 1.

[0027] The spring 2-5 is V-shaped and is formed by a thin spring steel plate. The bottom of the spring 2-5 is an arc-shaped bottom sleeved on the pin 2-4. The two arms of the spring 2-5 are respectively against the clamping plate 2-3 and the cylinder frame 2-1. The clamping plate 2-3 and the pin 2-4 have two rotating pairs spaced apart, and the spring 2-5 is located between the two rotating pairs.
