Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to an intestinal anastomosis device. Background Technology

[0002] Intestinal anastomosis is a common surgical procedure used to reconnect severed or resected portions of the intestine to restore its continuity and function. This surgery is typically performed in various situations, such as intestinal obstruction, intestinal tumors, trauma, or inflammatory bowel disease. Intestinal anastomosis is a complex but important surgical procedure that effectively restores intestinal function and is a key measure in the treatment of many digestive system diseases.

[0003] During current intestinal anastomosis surgery, the severed intestinal segment experiences a brief period of ischemia, causing it to contract in order to protect the tissue. This contraction makes it difficult to accurately align the two intestinal segments. To reduce these effects, doctors need to precisely unfold the intestinal section to ensure proper alignment and tension distribution, which increases the difficulty of the surgery.

[0004] To address these issues, we provide an intestinal anastomosis device. Utility Model Content

[0005] The purpose of this invention is to provide an intestinal anastomosis device that, by adjusting the settings of the components, solves the problem in the prior art that the intestinal cross-section is prone to shrinkage during intestinal anastomosis, and that the shrinkage of the intestinal segment makes it difficult to accurately align the ends of the two intestinal segments.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is an intestinal anastomosis device, including a protective shell, a cover fixedly connected to the surface of the protective shell, and puncture grooves opened on the surfaces of both the protective shell and the cover.

[0008] An adjustment assembly is provided inside the protective shell. The adjustment assembly includes a screw that is movably connected inside the protective shell. A push plate is threaded onto the surface of the screw, and a pressure plate is fixedly connected inside the protective shell.

[0009] The present invention is further configured such that both the protective shell and the shield are made of medical-grade polyethylene material, and one side of the push plate is in contact with the surface of the pressure plate.

[0010] The present invention is further configured such that an insertion rod is fixedly connected to one side of the protective shell, and the insertion rod is conical.

[0011] The present invention is further configured such that a knob is fixedly connected to the other end of the screw, and the number of the shields is ten.

[0012] The present invention is further configured such that a limiting rod is slidably connected inside the push plate, and one end of the limiting rod is fixedly connected to the inner wall of the protective shell.

[0013] The present invention is further configured such that a puncture needle is provided on one side of the protective shell, and a suture is installed on one side of the puncture needle.

[0014] The present invention is further configured such that there are ten puncture grooves and the distance between the protective shell and the shield is 3-5 mm.

[0015] This utility model has the following beneficial effects:

[0016] This invention, through the adjustment of the component settings, allows the protective shell to be placed inside the intestinal cross-section during intestinal suturing. By rotating the screw, the push plate is driven to push the protective shell, allowing it to expand from the inside out, unfolding the contracted intestinal cross-section. This facilitates suturing of the intestinal tube by medical staff, increases the anastomosis of the intestinal tube, and is beneficial to the recovery effect after intestinal suturing.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments. Specific Implementation

[0026] Please see Figure 1-5 This utility model is an intestinal anastomosis device, including a protective shell 1, a cover 2 fixedly connected to the surface of the protective shell 1, and puncture grooves 3 on the surfaces of both the protective shell 1 and the cover 2; an adjustment component is provided inside the protective shell 1, the adjustment component includes a screw 4, the screw 4 is movably connected inside the protective shell 1, a push plate 5 is threadedly connected to the surface of the screw 4, and a pressure plate 6 is fixedly connected inside the protective shell 1.

[0027] Specifically: There are two sets of protective shells 1, which can be inserted into two sections of the intestinal tract respectively. Both protective shells 1 and shields 2 are made of medical-grade polyethylene, which gives protective shells 1 a certain degree of toughness. When push plate 5 pushes pressure plate 6 to move, protective shells 1 can expand outward evenly. The puncture grooves 3 of protective shells 1 and shields 2 are designed to be through, which can facilitate the puncture needle 10 to puncture the intestinal wall from the inside to the outside. The surface of screw 4 is provided with external threads, and the inner wall of push plate 5 is provided with internal threads, which can adjust the position of push plate 5 when screw 4 rotates. Specific Implementation

[0028] Please see Figure 1-5 Based on the first specific embodiment, both the protective shell 1 and the shield 2 are made of medical polyethylene. One side of the push plate 5 is in contact with the surface of the pressure plate 6. An insertion rod 7 is fixedly connected to one side of the protective shell 1. The insertion rod 7 is conical. A knob 8 is fixedly connected to the other end of the screw 4. There are ten shields 2. A limiting rod 9 is slidably connected inside the push plate 5. One end of the limiting rod 9 is fixedly connected to the inner wall of the protective shell 1. A puncture needle 10 is provided on one side of the protective shell 1. A suture 11 is installed on one side of the puncture needle 10. There are ten puncture grooves 3. The distance between the protective shell 1 and the shield 2 is 3-5 mm.

[0029] Specifically: the surface of the pressure plate 6 is inclined, which can expand the protective shell 1 outward when the push plate 5 contacts the pressure plate 6; the insertion rod 7 is conical, which can be easily inserted into the cross-section of the intestinal tube and play a supporting role inside the intestinal tube; the limiting rod 9 slides inside the push plate 5 and can support the horizontal movement of the push plate 5; the puncture needle 10 cooperates with the suture 11 to suture the intestinal tube.

[0030] The working principle of this utility model is as follows: Medical staff manually move the protective shell 1, inserting the two sets of protective shells 1 into the two cross-sections of the intestinal tube respectively, and then manually push the shield 2 to completely cover the intestinal tube with the surface of the protective shell 1. Figure 4 As shown;

[0031] Then, manually rotate knob 8. Knob 8, together with screw 4, drives push plate 5 to move. Push plate 5 pushes pressure plate 6 to move. Pressure plate 6 drives protective shell 1 and cover 2 to expand outward evenly, unfolding the constricted intestinal section, making it easier for medical staff to suture the intestinal tube, while increasing the anastomosis of the intestinal tube, which is beneficial to the recovery effect after intestinal suture.

[0032] After the intestinal section is unfolded, medical staff can use a puncture needle 10 and suture 11 to puncture the intestinal wall outward along the puncture groove 3 inside the protective shell 1, such as... Figure 4 As shown;

[0033] After the puncture is completed, knob 8 can be manually turned in the opposite direction to retract the protective shell 1, thus removing its support for the intestinal wall. Then, the two sets of protective shells 1 can be moved relative to each other, allowing the protective shell 1 to exit the intestinal tube. Figure 5 As shown, this can effectively improve the suturing effect of the intestinal tract.
