Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical surgical tools, and in particular relates to a wound closing tool for digestive endoscopic surgery. Background Art
[0002] With the development of medicine, more and more digestive endoscopic surgeries are performed, such as endoscopic submucosal dissection (ESD), endoscopic submucosal tumor excision (ESE), endoscopic full-thickness resection (EFTR), etc. These digestive endoscopic surgeries are widely performed in large hospitals and even in grassroots hospitals. The surgical incisions are getting bigger and bigger, but how to close the large incisions of endoscopic surgery is an urgent problem to be solved.
[0003] During endoscopic surgery on a wound, a V-shaped metal clip is often needed to close the two sides of the wound in the width direction and then seal it. However, if the width of the wound is larger than the opening size of the V-shaped metal clip, it is difficult to close the wound with an ordinary V-shaped metal clip. The existing three-arm clamp (price 2,000 yuan) and OTSC clamp (more than 10,000 yuan) can reduce or close slightly larger wounds, but they are expensive and difficult to obtain.
[0004] Therefore, it is necessary to design a wound closure tool with lower cost. Utility Model Content
[0005] In order to solve the above problems existing in the prior art, the present invention provides a wound closing tool for digestive endoscopic surgery.
[0006] The technical solution adopted by the utility model is:
[0007] A wound closing tool for digestive endoscopic surgery comprises a silicone sleeve, a transparent tubular cap, a first V-shaped metal clip and a second V-shaped metal clip; the transparent tubular cap is connected to the front end of the silicone sleeve, the front end of the transparent tubular cap extends out of the silicone sleeve, and a U-shaped notch is arranged on the side wall of the front end of the transparent tubular cap; the first V-shaped metal clip is arranged outside the silicone sleeve, and the second V-shaped metal clip is arranged inside the silicone sleeve; the front end of one side arm of the second V-shaped metal clip is connected to the front end of one side arm of the first V-shaped metal clip at the U-shaped notch; the first V-shaped metal clip and the second V-shaped metal clip can clamp the opposite sides of the wound.
[0008] As an alternative or supplement to the above-mentioned wound closing tool: the transparent tubular cap is in the shape of a round tube, and the rear end of the transparent tubular cap is bonded to the silicone sleeve.
[0009] As an alternative or supplement to the above wound closing tool: the side arm of the second V-shaped metal clip is connected to the side arm of the first V-shaped metal clip by a tether.
[0010] As an alternative or supplement to the above wound closing tool: the rear end of the first V-shaped metal clip is connected to a first operating rod, and the first operating rod is used to release the first V-shaped metal clip and close the front end of the first V-shaped metal clip.
[0011] As an alternative or supplement to the above wound closing tool: the rear end of the second V-shaped metal clip is connected to a second operating rod, and the second operating rod is used to release the second V-shaped metal clip and close the front end of the second V-shaped metal clip.
[0012] As an alternative or supplement to the above wound closing tool: the first operating rod and the second operating rod can move forward and backward relative to the silicone sleeve.
[0013] The beneficial effects of the utility model are:
[0014] 1. This solution uses two V-shaped metal clips to pull the two sides of the large wound, thereby closing the large wound to form two small wounds, so as to facilitate the wound closure operation;
[0015] 2. This solution only requires a grooved transparent cap, two ordinary metal V-shaped metal clips and surgical sutures. The assembly is simple, safe and effective. It can replace high-value consumables to reduce large wounds, thereby facilitating wound closure operations. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solution in this embodiment will be clearly and completely described below in conjunction with the accompanying drawings. The described embodiments are only some of the embodiments, not all of them. Based on the embodiments in this solution, all other embodiments obtained by ordinary technicians in this field without making creative work are within the protection scope of this solution.
[0022] Example 1
[0023] like Figures 1 to 3 As shown, this embodiment designs a wound closing tool for digestive endoscopic surgery, including a silicone sleeve 1, a transparent tubular cap 2, a first V-shaped metal clip 6, a second V-shaped metal clip 9 and other components.
[0024] The transparent tubular cap 2 is connected to the front end of the silicone sleeve 1. The transparent tubular cap 2 is in a round tube shape, and the rear end of the transparent tubular cap 2 is bonded to the silicone sleeve 1. The front end of the transparent tubular cap 2 extends out of the silicone sleeve 1, and a U-shaped notch 7 is provided on the side wall of the front end of the transparent tubular cap 2. The transparent tubular cap 2 can be made of hard PVC material, and the transparent tubular cap 2 can be bonded to the transparent tubular cap 2 by glue. The inner diameter of the transparent tubular cap 2 does not exceed 0.9 cm, and the inner diameter of the silicone sleeve 1 is about 1 cm. The transparent tubular cap 2 is transparent because the material itself does not affect the field of vision, so that it is convenient to observe the closed state of the wound during the sealing operation.
[0025] The first V-shaped metal clip 6 is arranged outside the silicone sleeve 1, and the second V-shaped metal clip 9 is arranged inside the silicone sleeve 1; the front end of one side arm of the second V-shaped metal clip 9 is connected to the front end of one side arm of the first V-shaped metal clip 6 at the U-shaped notch.
[0026] The side arm of the second V-shaped metal clip 9 is connected to the side arm of the first V-shaped metal clip 6 by a tether 5. The tether 5 can be directly used as a suture for closing the wound 8.
[0027] The two side arms of the second V-shaped metal clip 9 and the first V-shaped metal clip 6 can be a movable side arm and a fixed side arm respectively, and the fixed side arm of the second V-shaped metal clip 9 is fixedly connected to the fixed side arm of the first V-shaped metal clip 6 .
[0028] The two side arms of the second V-shaped metal clamp 9 and the first V-shaped metal clamp 6 may also both be movable side arms, and one movable side arm of the second V-shaped metal clamp 9 is rotatably connected to one movable side arm of the first V-shaped metal clamp 6 .
[0029] The first V-shaped metal clip 6 and the second V-shaped metal clip 9 can clamp the opposite sides of the wound
[0030] The first operating rod 3 and the second operating rod 4 can move forward and backward relative to the silicone sleeve 1, so that the connection between the second V-shaped metal clip 9 and the first V-shaped metal clip 6 is located at the U-shaped notch 7 of the transparent tubular cap 2. When the middle of the wound 8 is sealed with the assistance of the first V-shaped metal clip 6 and the second V-shaped metal clip 9, or when the digestive endoscope is inserted into the digestive tract, the two operating rods can be retracted into the transparent cap to prevent damage to the pharyngeal and esophageal mucosa when the endoscope is inserted or withdrawn.
[0031] The manufacturing process of the wound closing tool for digestive endoscopic surgery in this embodiment is as follows:
[0032] 1. Make a transparent tubular cap 2 with a U-shaped notch 7 and wear it on the front end of the silicone sleeve 1 of the endoscope;
[0033] 2. Place a V-shaped metal clip (first V-shaped metal clip 6) on the inside of the transparent cap through the endoscope clamp channel, and place another V-shaped metal clip (second V-shaped metal clip 9) directly on the outside of the transparent cap;
[0034] 3. Use surgical suture (tether 5) to tie the front ends of the two V-shaped metal clips;
[0035] 4. Adjust the positions of the two bound V-shaped metal clips and place them accurately on the inner and outer sides of the U-shaped notch 7 of the transparent cap.
[0036] The use process of the wound closing tool for digestive endoscopic surgery in this embodiment is as follows:
[0037] 1. Deliver the wound closing tool for digestive endoscopic surgery to wound 8;
[0038] 2. First, clamp the tissue on one side of the wound 8 with the first V-shaped metal clip 6, and operate the first operating rod 3 to release the first V-shaped metal clip 6;
[0039] 3. Move the front end of the wound closing tool for digestive endoscopic surgery, pull the wound 8 tissue clamped by the first V-shaped metal clip 6 to the opposite side of the wound 8, and clamp the wound tissue on the opposite side with the second V-shaped metal clip 9;
[0040] 4. Operate the second operating lever 4 to release the second V-shaped metal clip 9, so that one large wound becomes two small wounds, and then use other V-shaped metal clips to completely close the small wounds. A large wound refers to a wound 8 whose width is larger than the opening of the V-shaped metal clip, and a small wound refers to a wound 8 whose width is smaller than the opening of the V-shaped metal clip.
[0041] The wound closing tool for digestive endoscopic surgery in this embodiment can be obtained locally at primary hospitals. Two ordinary V-shaped metal clips can be used to suture a large wound, and the cost is about 400 yuan. Compared with consumables in the prior art such as three-arm clamps (price 2,000 yuan) and OTSC clamps (more than 10,000 yuan), the medical cost of suture a large wound with the structure in this embodiment is greatly reduced.
[0042] The above embodiments are merely examples for the purpose of clarifying the description, and are not intended to limit the implementation methods; it is not necessary and impossible to list all implementation methods exhaustively. However, obvious changes or modifications derived therefrom are still within the scope of protection of the present technology.
