Abstract
Description
Technical Field
[0001] This utility model relates to the field of colorectal surgery technology, and in particular to a colorectal fixation and traction auxiliary device. Background Technology
[0002] During gastrointestinal surgery, an incision is made in the abdominal cavity to pull out and fix the affected area of the colon and rectum before removing or treating it. To maintain the stability of the pulled-out and fixed area, the colon and rectum usually need to be further fixed. During the resection process, gauze needs to be placed at the abdominal incision site to prevent blood from flowing into the abdominal cavity and causing infection. However, traditional gauze has a weak sealing effect and needs to be constantly replaced and added to improve the anti-leakage effect, which is very inconvenient. Utility Model Content
[0003] This utility model discloses an auxiliary device for fixing and pulling out colorectal tissue, which aims to solve the technical problem of blood and dirt flowing back into the abdominal cavity during colorectal resection.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] An auxiliary device for fixing and pulling out a colon and rectum includes two sets of limiting and fixing plates. The limiting and fixing plates are arc-shaped, and a semi-circular groove is opened on one side of each limiting and fixing plate. After the two sets of limiting and fixing plates are spliced together, the colon and rectum are limited through the groove. A collection groove is provided at both ends of the limiting and fixing plates. Surgical waste will slide down the surface of the arc-shaped limiting and fixing plates into the collection grooves at both ends for collection and discharge through the drain port at the bottom of the collection groove. A limiting mechanism is provided at both ends of the limiting and fixing plates. The limiting mechanism is used to fix the limiting and fixing plates to the bed edge or support them on the bed surface. The limiting mechanism includes telescopic members rotatably connected to both ends of the limiting and fixing plates. Two sets of clamps are movably provided at the ends of the telescopic members. The telescopic members are telescopic frames with adjustable length.
[0006] By setting two sets of limiting and fixing plates with slots, the pulled-out colon and rectum can be assisted in fixing. Medical staff can then perform resection surgery on the limited portion of the colon and rectum. During the resection, the waste fluid produced will slide down the surface of the limiting and fixing plates to both ends and be collected in the collection slot, which can effectively prevent the waste fluid from flowing back into the abdominal cavity and causing infection.
[0007] In a preferred embodiment, the edge of the limiting and fixing plate is provided with anti-overflow strips except for the slot, which can effectively prevent the overflow of sewage and prevent the saline irrigation solution used during the operation from overflowing.
[0008] In a preferred embodiment, an airbag ring is provided on the inner wall of the groove, and a vent that communicates with the airbag ring is provided on the side of the limiting and fixing plate away from the groove.
[0009] The airbag ring in the slot can be expanded by introducing gas, thereby further limiting and clamping the colon and rectum located in the slot, ensuring a seal while being able to accommodate colons and rectums of different diameters.
[0010] In a preferred embodiment, the limiting mechanism further includes a fixed plate fixed to one end of the telescopic frame. A knob is rotatably connected to one end of the fixed plate. Gears are fixed to one end of each of the two sets of clamps. The knob is fixedly connected to one set of gears. The limiting mechanism further includes a limiting block slidably connected to one end of the fixed plate. Gear grooves are formed on the outer surface of the limiting block and the outer surface of the knob. The limiting block is slidably connected to a groove at one end of the fixed plate, and the limiting block slides elastically through a spring in the groove.
[0011] By rotating the knob and driving the gears, the two sets of clamping plates can move relative to each other and expand in opposite directions, thereby realizing clamping and expansion operations. The limit block with tooth groove can prevent the knob from rotating on its own, thus realizing the self-locking function of the knob.
[0012] In a preferred embodiment, the opposing surfaces of the two sets of limiting and fixing plates are magnetically attracted, which can further improve the sealing and stability of the limiting and fixing plates after splicing.
[0013] As can be seen from the above, the colorectal fixation and traction auxiliary device provided by this utility model has the following technical effects.
[0014] Firstly, the two sets of limiting and fixing plates, along with the slots, can limit and fix the colon and rectum, while medical staff can perform resection surgery on the limited portion of the colon and rectum. During the resection, the waste fluid produced will slide down the surface of the limiting and fixing plates to both ends and be collected in the collection slot, which can effectively prevent the waste fluid from flowing back into the abdominal cavity and causing infection.
[0015] Secondly, the lower surface of the arc-shaped limiting and fixing plate will be located on the patient's abdominal surface, making the limiting and fixing plate closer to the patient's abdomen and more in line with the human physiological curve. This can effectively prevent the colon and rectum from being pulled out too much, and the arc surface is more conducive to the flow and collection of sewage.
[0016] Thirdly, the telescopic frames at both ends of the limiting and fixing plate can be adjusted in length to fix the clamping plate to the bed frame, thereby further improving the stability of the limiting and fixing plate. The telescopic frames can be rotated downwards by 90 degrees and fixed, and the clamping plate can be expanded outwards, so that the limiting and fixing plate can be supported on the bed surface by the telescopic frames and clamping plates. The two fixing and installation methods make the device more versatile. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0026] The colorectal fixation and traction auxiliary device disclosed in this utility model is mainly used in scenarios where blood stains flow back into the abdominal cavity during colorectal resection and the gauze has poor seepage prevention effect.
[0027] Reference Figures 1-6An auxiliary device for fixing and pulling out the colon and rectum includes two sets of limiting and fixing plates 1. The limiting and fixing plates 1 are arc-shaped, and a semi-circular groove 2 is opened on one side of the limiting and fixing plates 1. After the two sets of limiting and fixing plates 1 are spliced together, the colon and rectum are limited through the groove 2. The limiting and fixing plates 1 are provided with receiving grooves 3 at both ends. The surgical waste will slide down the surface of the arc-shaped limiting and fixing plates 1 into the receiving grooves 3 at both ends for collection, and then be discharged through the drain port 4 at the bottom of the receiving groove 3.
[0028] In this embodiment, when a colorectal resection is required, the colorectal tissue can first be pulled outward from the abdominal incision. Then, the two sets of limiting and fixing plates 1 are moved to the patient's abdominal incision site. By closing the two sets of limiting and fixing plates 1, the colorectal tissue is limited and fixed by the groove 2. Figure 3 As shown, in this state, the lower surface of the arc-shaped limiting and fixing plate 1 will be located on the surface of the patient's abdomen, making the limiting and fixing plate 1 closer to the patient's abdomen and more in line with the physiological curve of the human body. This can effectively prevent the colon and rectum from being pulled out too much. Medical staff can then perform resection surgery on the limited portion of the colon and rectum. During the resection, the waste fluid produced will slide down the surface of the limiting and fixing plate 1 to both ends and be collected in the collection tank 3, which can effectively prevent the waste fluid from flowing back into the abdominal cavity and causing infection.
[0029] The limiting and fixing plate 1 is provided with limiting mechanisms at both ends. The limiting mechanisms are used to fix the limiting and fixing plate 1 to the edge of the bed or support it on the bed surface. The limiting mechanisms include telescopic members that are rotatably connected to both ends of the limiting and fixing plate 1. Two sets of clamping plates 10 are movably provided at the ends of the telescopic members. The telescopic members are telescopic frames 8 with adjustable length.
[0030] In this embodiment, the telescopic frames 8 at both ends of the limiting and fixing plate 1 can be adjusted in length to fix the clamping plate 10 to the bed frame, thereby further improving the stability of the limiting and fixing plate 1. The telescopic frames 8 can rotate downwards by ninety degrees and be fixed, and the clamping plate 10 can expand outwards, so that the limiting and fixing plate 1 can be supported on the bed surface by the telescopic frames 8 and the clamping plate 10. Figure 6 As shown, the two fixed installation methods make the device more versatile.
[0031] Specifically, except for the slot 2, the edge of the limiting and fixing plate 1 is equipped with anti-overflow strips 5, which can effectively prevent the overflow of sewage and prevent the saline rinsing solution used during the operation from overflowing.
[0032] Reference Figure 1 and Figure 2In a preferred embodiment, an airbag ring 6 is provided on the inner wall of the slot 2, and a vent 7 communicating with the airbag ring 6 is provided on the side of the limiting and fixing plate 1 away from the slot 2. The airbag ring 6 in the slot 2 can be expanded by introducing gas, thereby further limiting and clamping the colon and rectum located in the slot 2, ensuring sealing while being able to adapt to colons and rectums of different diameters.
[0033] Furthermore, the opposing surfaces of the two sets of limiting and fixing plates 1 are magnetically attracted, which can further improve the sealing and stability of the limiting and fixing plates 1 after splicing.
[0034] Reference Figure 4 and Figure 5 In a preferred embodiment, the limiting mechanism further includes a fixing plate 9 fixed to one end of the telescopic frame 8. A knob 11 is rotatably connected to one end of the fixing plate 9. Gears 12 are fixed to one end of each of the two sets of clamping plates 10. The knob 11 is fixedly connected to one set of gears 12. The limiting mechanism also includes a limiting block 13 slidably connected to one end of the fixing plate 9. The outer surface of the limiting block 13 and the outer surface of the knob 11 are both provided with toothed grooves. The limiting block 13 is slidably connected through a sliding groove 14 at one end of the fixing plate 9, and the limiting block 13 is elastically slid by a spring in the sliding groove 14.
[0035] In this embodiment, the rotation of the knob 11 and the transmission of the gear 12 enable the two sets of clamping plates 10 to move relative to each other and expand in opposite directions, thereby realizing the clamping and expansion operation. The limiting block 13 can slide elastically through the spring in the slide groove 14. The elasticity of the spring can ensure that the limiting block 13 is in contact with the knob 11. The tooth groove can prevent the knob 11 from rotating, thereby realizing the self-locking function of the knob 11.
[0036] Working principle: First, the colon and rectum are pulled outward from the abdominal incision. Then, the two sets of limiting and fixing plates 1 are moved to the patient's abdominal incision. By closing the two sets of limiting and fixing plates 1, the colon and rectum are limited and fixed by the grooves 2. Figure 3 As shown, gas is then introduced into the airbag ring 6 through the vent 7 to inflate it, thereby further limiting and clamping the colon and rectum located in the slot 2. Next, the length of the telescopic frame 8 is adjusted so that the clamping plate 10 is clamped to the edge of the bed to fix the position of the limiting and fixing plate 1. Alternatively, the telescopic frame 8 can be rotated downwards by ninety degrees, and the clamping plate 10 can be expanded outwards by rotating the knob 11. Figure 5 This allows the limiting and fixing plate 1 to be supported on the bed surface. Subsequently, medical staff can perform resection surgery on the limited part of the colon and rectum. During the resection, the waste fluid produced will slide down the surface of the limiting and fixing plate 1 to both ends and be collected in the collection tank 3, which can effectively prevent the waste fluid from flowing back into the abdominal cavity and causing infection.
[0037] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
