Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a connector that prevents detachment between the end of a gastrointestinal decompression tube and a negative pressure drainage device. Background Technology

[0002] In the field of hepatobiliary and gastrointestinal surgery, accurate diagnosis and effective treatment of various diseases have always been the core pursuit of medical development. With the increasing aging population and changing lifestyles, the incidence of hepatobiliary and gastrointestinal diseases is on the rise. Malignant tumors such as liver cancer, stomach cancer, and colorectal cancer seriously threaten patients' lives and health, while common diseases such as cholecystitis, gallstones, gastric ulcers, and enteritis also greatly affect patients' quality of life. Currently, surgery remains an important treatment for many hepatobiliary and gastrointestinal diseases, but traditional surgery is highly invasive, has a slow recovery time, and a high risk of postoperative complications. In recent years, minimally invasive surgery has made significant progress, such as the widespread use of laparoscopic and endoscopic surgery; however, it still requires extremely high precision and stability of surgical instruments and the surgeon's skill.

[0003] However, the existing anti-dislodgement connector between the end of the gastrointestinal decompression tube and the negative pressure drainage device has the following disadvantages:

[0004] (1) The existing anti-detachment connector between the end of the gastrointestinal decompression tube and the negative pressure drainage device is difficult to make the end of the gastrointestinal decompression tube and the negative pressure drainage device tightly clamped together, so as to prevent relative displacement between them.

[0005] (2) The existing gastrointestinal decompression tube ends and negative pressure drainage device anti-detachment connectors make it difficult for medical staff to replace the arc-shaped splints of different specifications or materials according to the actual situation, so as to better adapt to the individual differences and treatment needs of patients.

[0006] Therefore, this utility model provides a connection to prevent the gastrointestinal decompression tube from falling off between the end of the tube and the negative pressure drainage device. Utility Model Content

[0007] (a) Technical problems to be solved

[0011] Optionally, a limiting rod is fixedly connected to the inner bottom wall of the cavity, and a slot adapted to the limiting rod is provided at the bottom of the sliding block. The limiting rod is movably connected inside the slot, and the limiting rod can ensure the stability of the sliding block when it moves.

[0012] Optionally, a limiting block is fixedly connected to the other side of the slider, and a limiting groove adapted to the limiting block is provided on the inner wall of the rectangular groove. The limiting block is movably connected to the inner wall of the limiting groove, and the limiting block can ensure that the slider moves in a specific position.

[0013] Optionally, an anti-slip pad is fixedly connected to the inner surface of the arc-shaped clamp. The anti-slip pad is made of rubber and can ensure that the pressure reducing tube will not easily slip or shift.

[0014] Optionally, a positioning rod is fixedly connected to one side of the arc-shaped clamping plate, and a positioning groove adapted to the positioning rod is provided on one side of the connecting block. The positioning rod can enable the arc-shaped clamping plate to be accurately installed in a predetermined position.

[0016] (III) Beneficial Effects

[0017] This utility model provides an anti-detachment connector between the end of a gastrointestinal decompression tube and a negative pressure drainage device, which has the following beneficial effects:

[0018] 1. The anti-dislodgement connector between the end of the gastrointestinal decompression tube and the negative pressure drainage device, through the setting of a bidirectional threaded rod, a knob, a slider, a connecting block, and an arc-shaped clamp, allows for the following steps when connecting the gastrointestinal decompression tube and the negative pressure drainage device: First, the two arc-shaped clamps clamp the connection points of the end of the gastrointestinal decompression tube and the negative pressure drainage device respectively. Then, rotating the knob drives the bidirectional threaded rod to rotate, causing the two sliders threaded to move towards each other. This causes the two arc-shaped clamps to move towards the center through the connecting block, making them contact the surfaces of the end of the gastrointestinal decompression tube and the negative pressure drainage device respectively, and gradually applying pressure. This ensures that the end of the gastrointestinal decompression tube and the negative pressure drainage device are tightly clamped together, thereby preventing relative displacement between them and achieving the anti-dislodgement effect.

[0019] 2. The anti-dislodgement connector between the end of the gastrointestinal decompression tube and the negative pressure drainage device is designed with a locking plate, a pressing block, a sliding block, a spring, a connecting plate, and a locking block. When the arc-shaped clamp needs to be replaced, first press the pressing block to move the sliding block downwards, and at the same time compress the spring, causing the connecting plate connected to the sliding block to move downwards synchronously, which in turn moves the locking block downwards until the locking block completely disengages from the round hole at the bottom of the locking plate. This releases the locking state between the arc-shaped clamp and the connecting block, allowing medical staff to remove the old arc-shaped clamp from the connecting block and replace it with a new one. This allows medical staff to replace the arc-shaped clamp with one of different specifications or materials according to the actual situation, in order to better adapt to the individual differences and treatment needs of patients.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0028] Please see Figures 1 to 4This utility model provides a technical solution: a connection between the end of a gastrointestinal decompression tube and a negative pressure drainage device to prevent detachment, including a mounting block 1. A fixing component 13 is fixedly connected to one side of the mounting block 1. A rectangular groove is opened on the other side of the mounting block 1. A bidirectional threaded rod 2 is rotatably connected to the inner wall of the rectangular groove. A knob 3 is fixedly connected to one end of the bidirectional threaded rod 2. Two sliders 4 are threadedly connected to the surface of the bidirectional threaded rod 2. A connecting block 5 is fixedly connected to one side of each slider 4. An arc-shaped clamp 6 is provided on one side of the connecting block 5. The connection is achieved through the bidirectional threaded rod 2, the knob 3, the sliders 4, the connecting block 5, and the arc-shaped clamp 6. The design of the two arc-shaped clamps 6 is as follows: When connecting the gastrointestinal decompression tube and the negative pressure drainage device, firstly, the two arc-shaped clamps 6 clamp the connection points of the gastrointestinal decompression tube and the negative pressure drainage device respectively. Then, rotating the knob 3 drives the bidirectional threaded rod 2 to rotate, causing the two sliders 4 to move towards each other along the bidirectional threaded rod 2. This causes the two arc-shaped clamps 6 to move towards the center through the connecting block 5, so that they contact the surfaces of the gastrointestinal decompression tube and the negative pressure drainage device respectively, and gradually apply pressure. This ensures that the gastrointestinal decompression tube and the negative pressure drainage device are tightly clamped together, thereby preventing relative displacement between them and achieving [the desired effect]. To prevent detachment, a clamping plate 7 is fixedly connected to one side of the arc-shaped clamping plate 6. A cavity is formed inside the connecting block 5, and a pressing block 8 is movably connected to the inner wall of the cavity. A sliding block 9 is fixedly connected to the bottom of the pressing block 8. A spring 10 is connected between the bottom of the sliding block 9 and the inner bottom wall of the cavity. A connecting plate 11 is fixedly connected to one side of the sliding block 9, and a clamping block 12 is fixedly connected to the top of the connecting plate 11. A round hole matching the clamping block 12 is formed at the bottom of the clamping plate 7. Through the arrangement of the clamping plate 7, pressing block 8, sliding block 9, spring 10, connecting plate 11, and clamping block 12, when the arc needs to be replaced... When using the arc-shaped splint 6, first press the pressing block 8 to move the sliding block 9 downwards, and at the same time compress the spring 10, so that the connecting plate 11 connected to the sliding block 9 moves downwards in sync, causing the locking block 12 to move downwards until the locking block 12 is completely disengaged from the round hole at the bottom of the locking plate 7. This will release the locking state between the arc-shaped splint 6 and the connecting block 5. Medical staff can then remove the old arc-shaped splint 6 from the connecting block 5 and replace it with a new arc-shaped splint 6. This allows medical staff to replace the arc-shaped splint 6 with different specifications or materials according to the actual situation, so as to better adapt to the individual differences and treatment needs of patients.

[0029] A limiting rod 14 is fixedly connected to the inner bottom wall of the cavity. By setting the limiting rod 14, the limiting rod 14 can ensure the stability of the sliding block 9 when it moves. The bottom of the sliding block 9 is provided with a slot that matches the limiting rod 14. The limiting rod 14 is movably connected to the inside of the slot.

[0030] A limiting block 15 is fixedly connected to the other side of the slider 4. By setting the limiting block 15, the limiting block 15 can ensure that the slider 4 moves in a specific position. The inner wall of the rectangular groove is provided with a limiting groove that matches the limiting block 15. The limiting block 15 is movably connected to the inner wall of the limiting groove.

[0031] An anti-slip pad 16 is fixedly connected to the inner surface of the arc-shaped clamp 6. The anti-slip pad 16 ensures that the pressure reducing tube will not easily slip or shift. The anti-slip pad 16 is made of rubber.

[0032] A positioning rod 17 is fixedly connected to one side of the arc-shaped clamping plate 6. With the setting of the positioning rod 17, the arc-shaped clamping plate 6 can be accurately installed in the predetermined position. A positioning groove adapted to the positioning rod 17 is opened on one side of the connecting block 5.

[0033] The top of the pressing block 8 is fixedly connected to the anti-slip plate 18. With the setting of the anti-slip plate 18, the anti-slip plate 18 can reduce the error of multiple pressing or incomplete pressing caused by hand slippage. The top of the anti-slip plate 18 is provided with anti-slip texture.

[0034] In this invention, the working steps of the device are as follows:

[0035] First step: First, clamp the two arc-shaped clamps 6 to the connection between the end of the gastrointestinal decompression tube and the negative pressure drainage device. Then, turn the knob 3 to drive the bidirectional threaded rod 2 to rotate, so that the two sliders 4 move towards each other along the bidirectional threaded rod 2. This causes the two arc-shaped clamps 6 to move towards the middle through the connecting block 5, so that they contact the end of the gastrointestinal decompression tube and the surface of the negative pressure drainage device respectively and gradually apply pressure, so that the end of the gastrointestinal decompression tube and the negative pressure drainage device are tightly clamped together, thereby preventing relative displacement between them and achieving the effect of preventing them from falling off.

[0036] The second step: Press the pressing block 8 to move the sliding block 9 downwards, and at the same time compress the spring 10, so that the connecting plate 11 connected to the sliding block 9 moves downwards in sync, causing the locking block 12 to move downwards until the locking block 12 is completely disengaged from the round hole at the bottom of the locking plate 7. This releases the locking state between the arc-shaped clamp 6 and the connecting block 5. Medical staff can then remove the old arc-shaped clamp 6 from the connecting block 5 and replace it with a new arc-shaped clamp 6. This allows medical staff to replace the arc-shaped clamp 6 with different specifications or materials according to the actual situation, so as to better adapt to the individual differences and treatment needs of patients.
