Description

Technical Field

[0001] The utility model relates to an adjustable painless anal canal, belonging to the technical field of medical products. Background Art

[0002] In rectal surgery, anastomotic leakage is one of the most serious complications after surgery. In order to prevent the occurrence of postoperative anastomotic leakage, an anal tube is usually left in place during surgery to reduce intestinal pressure. The traditional method of fixing the anal tube is to suture it to the perianal skin with sutures. This fixation method has the following disadvantages: (1) Suture fixation to the perianal skin often causes patients to experience discomfort such as suture pain around the anus, anal distension, and the urge to defecate; (2) Suture fixation increases the risk of local skin infection; (3) The anal tube cannot be adjusted after suture fixation; (4) The anal tube is generally left in place for about 7 days. During the period of anal tube retention, it will limit the patient's sitting and mobility, affect the patient's early postoperative activities, and further affect the patient's intestinal function recovery and prolong hospitalization.

[0018] like Figure 2 As shown, the front end of the anal canal 1 is about 20 cm long and has a sewage suction hole 15, which can be cut according to the needs during the operation to adjust the length; the middle part of the anal canal 1 is a fixator connector 12, which is connected to the fixator; the rear end part of the anal canal 1 is an extended connection part, and a drainage bag interface 14 is provided at the end thereof, which can be connected to a drainage bag commonly used in clinical practice.

[0019] Specifically, the anal canal 1 includes an anal canal body 11, a fixer connector 12 is provided in the middle position of the anal canal body 11, at least one positioning groove 13 is provided on the peripheral wall of the fixer connector 12, a plurality of sewage suction holes 15 are evenly distributed on one side of the fixer connector 12 on the anal canal body 11, and a drainage bag interface 14 is provided at the end of the anal canal body 11 and on the other side of the fixer connector 12.

[0020] The fixator is composed of an anal canal connection fixing part 2 in the middle and skin adhesive fixing devices 4 on both sides. The two sides of the anal canal connection fixing part 2 are connected to the skin adhesive fixing devices 4 through a fixing line 3. The skin adhesive fixing device 4 includes an adhesive fixing sheet 43, such as Figure 1 As shown, a fixing line adjustable device is fixed on one side of the adhesive fixing sheet 43, and an adhesive that can be attached to the periphery of the patient's anus is provided on the other side.

[0021] like Figure 1 As shown, the fixing line adjustable device is used to clamp or release the other end of the fixing line 3, and the fixing line adjustable device includes an upper clamping plate 41 and a lower clamping plate 42. The upper clamping plate 41 and one end of the lower clamping plate 42 are rotatably connected by a pin or a rotating shaft. The surfaces of the upper clamping plate 41 and the lower clamping plate 42 on the opposite side are respectively provided with at least one groove 44 and at least one protrusion 45, and the number of the grooves 44 and the protrusions 45 is the same. Each groove 44 corresponds to the position of a protrusion 45 and the size is adapted. The grooves 44 and the protrusions 45 are perpendicular to the pins or rotating shafts at one end of the upper clamping plate 41 and the lower clamping plate 42. When the other ends of the upper clamping plate 41 and the lower clamping plate 42 are closed, each protrusion 45 is clamped in a corresponding groove 44; when the fixing line 3 needs to be clamped, the fixing line 3 is placed horizontally and crossed between the upper clamping plate 41 and the lower clamping plate 42, that is, it is cross-arranged with the protrusion 45 and the groove 44, and when the other ends of the upper clamping plate 41 and the lower clamping plate 42 are closed, the protrusion 45 and the groove 44 clamp the fixing line 3.

The two rotating curved plates 21 after the clamping connection are used to clamp the anal canal 1 and limit the anal canal 1 to prevent its axial movement and circumferential shaking. The two rotating curved plates 21 after the clamping connection form a hollow structure that matches the outer wall shape of the fixing connecting member 12 of the anal canal 1, as shown in FIG. Figure 5 shown.

[0023] like Figure 4 , Figure 5As shown, after the two rotating curved plates 21 are snap-connected, the positioning blocks 24 on the two rotating curved plates 21 form an annular structure, and a through hole 25 is formed in the middle, which is used to snap-connect the position of the positioning groove 13 of the fixing device connector 12. At least one positioning block 24 is provided on the inner wall of the two rotating curved plates 21, and the width, thickness and number of the positioning blocks 24 match the width, thickness and number of the positioning groove 13 of the anal canal 1. The side wall of the anal canal connecting part fixing member 2 is fixedly connected to one end of at least two fixing wires 3 (in this embodiment, the number of fixing wires 3 is two). In this embodiment, one end of the fixing wire 3 is fixed to the two rotating curved plates 21 respectively.
