Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a laparoscopic intestinal compressor. Background Technology

[0002] Laparoscopic surgery, also known as minimally invasive surgery, utilizes an endoscope, an endoscopic device, to be inserted into the abdominal cavity through a small incision. The laparoscope is equipped with a high-definition camera and light source, which can transmit images of the abdominal cavity to a display screen in real time for the surgeon to observe. By providing a clear field of vision and precise operation, it greatly improves the safety of the surgery and the quality of the patient's postoperative recovery. It has the advantages of minimal trauma, fewer complications, and faster postoperative recovery. Some instruments are also needed to assist in the operation, including bowel pressure forceps.

[0003] Intestinal depressors are instruments used to open the intestines. They are essential surgical instruments for laparoscopic gastrointestinal surgery. During the operation, they open the intestines and separate organs that may affect the surgical site, making it easier for the surgeon to observe and perform the operation, reducing interference during the procedure. They can also help separate tissues, making the operation smoother. In some cases, intestinal depressors can also be used for temporary hemostasis, especially when dealing with small blood vessels.

[0004] Existing rectal compressors consist of an operating handle and a retractor mounted on the operating handle. Medical personnel control the opening and closing of the retractor through the operating handle. During the operation, the retractor is first closed and inserted into the body. Then, the operating handle is used to open the retractor to support the body's tissues. However, when suturing the posterior wall of the anastomosis, a mesentery is needed to block the posterior wall of the intestine. Therefore, an assistant is required to push aside the mesentery to expose the location of the anastomosis. The operation is relatively complicated, which leads to a longer operation time, reduced work efficiency, and increased labor costs. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a laparoscopic intestinal depressor, which aims to improve the existing intestinal depressor technology. When suturing the posterior wall of the anastomosis, the intestinal wall of the human intestine is blocked by a mesentery, so an assistant is needed to push the mesentery aside to expose the location of the anastomosis. This makes the operation process cumbersome and prolongs the operation time.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a laparoscopic intestinal depressor, comprising a hollow tube, a handle fixedly connected to the right end of the hollow tube, a second sliding groove formed on the outer wall of the hollow tube, a limiting block slidably connected to the inner wall of the second sliding groove, an adjusting sleeve provided on the outer wall of the limiting block, the inner wall of the adjusting sleeve slidably connected to the outer wall of the limiting block, a second limiting ring fixedly connected to the bottom side of the limiting block, a second spring fixedly connected to the left side of the second limiting ring, a guide rod slidably connected to the inner wall of the second limiting ring, and a guide rod fixed at the middle of the outer wall of the guide rod. A limit ring is connected to the left end of the guide rod, and multiple rotating shafts are rotatably connected to the left end of each rotating shaft. A second connecting rod is fixedly connected to the outer wall of each rotating shaft. A second rotating shaft is rotatably connected to the left side of the second connecting rod. A first connecting rod is rotatably connected to the outer wall of the second rotating shaft. A rotating disk is rotatably connected to the left side of the first connecting rod. A rotating shaft is rotatably connected to the middle of the rotating disk. A clamp is fixedly connected to the outer wall of the rotating disk. A pull plate is rotatably connected to the inner wall of the handle. A quick-release structure is fixedly connected to the inner wall of the pull plate. The quick-release structure is used to quickly disassemble the device.

[0007] As a further description of the above technical solution:

[0008] The quick-release structure includes a hollow column, the bottom of which is fixedly connected to the inner wall of the pull plate. A sliding column is slidably connected to the inner wall of the hollow column. A spring is fixedly connected to the bottom end of the sliding column. A locking block is fixedly connected to the outer wall of the sliding column. A sliding groove is provided on the outer wall of the pull plate. A locking groove is provided on the right end of the guide rod.

[0009] As a further description of the above technical solution:

[0010] A rotating handle is fixedly connected to the bottom of the outer wall of the pull plate, and a collar is fixedly connected to the bottom end of the rotating handle.

[0011] As a further description of the above technical solution:

[0012] The inner wall of the slot is slidably connected to the outer wall of the block, and an anti-slip sleeve is fixedly connected to the top of the sliding column.

[0013] As a further description of the above technical solution:

[0014] A second collar is fixedly connected to the bottom of the handle, and a hook is fixedly connected to the outer wall of the second collar.

[0015] As a further description of the above technical solution:

[0016] A nameplate is fixedly connected to the front side of the handle, and the clamps are in the shape of a concave fan.

[0017] As a further description of the above technical solution:

[0018] The inner wall of the second collar is fixedly connected with an anti-slip pad, which is made of rubber.

[0019] As a further description of the above technical solution:

[0020] The outer wall of the adjusting sleeve is provided with multiple anti-slip textures, and the inner wall of the adjusting sleeve is threadedly connected to the outer wall of the hollow tube.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by rotating the pull plate, the guide rod is pulled, causing the limiting ring one to squeeze the spring two. The position of the limiting ring two is adjusted by rotating the adjusting sleeve. After releasing the pull plate, the guide rod moves to the left, squeezing the rotating shaft three, causing the first connecting rod and the second connecting rod to rotate along the rotating shaft three and rotating shaft two respectively. This opens the clamp, achieving the purpose of exposing the rectal space and rectal anastomosis, providing the surgeon with a field of vision for suturing, thus speeding up work efficiency, reducing operation time, and lowering labor costs.

[0023] 2. In this utility model, the sliding column is pressed down to move the locking block together, disengaging it from the locking groove. After cleaning, the guide rod is inserted along the sliding groove, causing the sliding column to compress the spring and move down. After reaching the locking position, the sliding column and the locking block rebound, thus locking the mechanism. This achieves the purpose of quickly disassembling the mechanism, making it easier to clean the patient's area, improving work efficiency and surgical safety. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see the appendix Figure 1 - Appendix Figure 3 This utility model provides an embodiment of a laparoscopic intestinal compressor, comprising a hollow tube 1, with a handle 4 fixedly connected to the right end of the hollow tube 1. A second groove 14 is formed on the outer wall of the hollow tube 1, and a limiting block 15 is slidably connected to the inner wall of the second groove 14. An adjusting sleeve 3 is provided on the outer wall of the limiting block 15, and the inner wall of the adjusting sleeve 3 is slidably connected to the outer wall of the limiting block 15. A second limiting ring 16 is fixedly connected to the bottom side of the limiting block 15, and a second spring 17 is fixedly connected to the left side of the second limiting ring 16. A guide rod 12 is slidably connected to the inner wall of the second limiting ring 16, and a first limiting ring 13 is fixedly connected to the middle of the outer wall of the guide rod 12. The left end of the guide rod 12 is rotatably connected to... There are multiple rotating shafts 3 8. The outer wall of the rotating shaft 3 8 is fixedly connected to a second connecting rod 11. The left side of the second connecting rod 11 is rotatably connected to a rotating shaft 2 7. The outer wall of the rotating shaft 2 7 is rotatably connected to a first connecting rod 10. The left side of the first connecting rod 10 is rotatably connected to a rotating disk 9. The middle part of the rotating disk 9 is rotatably connected to a rotating shaft 1 6. The outer wall of the rotating disk 9 is fixedly connected to a clamp 5. The inner wall of the handle 4 is rotatably connected to a pull plate 26. The inner wall of the pull plate 26 is fixedly connected to a quick-release structure 2. The quick-release structure 2 is used to quickly disassemble the device. The bottom of the outer wall of the pull plate 26 is fixedly connected to a rotating handle 18. The bottom end of the rotating handle 18 is fixedly connected to a collar 1 22.

[0034] Specifically, a rotating handle 18 is fixedly connected to the bottom of the outer wall of the pull plate 26, which makes it convenient for the user to rotate the pull plate 26. A collar 22 is fixedly connected to the bottom end of the rotating handle 18, which allows the user to insert their fingers, making it convenient to press the rotating handle 18 and preventing it from sliding during use. The inner wall of the adjusting sleeve 3 is slidably connected to the outer wall of the limiting block 15, so that the limiting block 15 will not be rotated when the adjusting sleeve 3 is rotated. At the same time, the movement of the adjusting sleeve 3 will drive the limiting block 15 to move together. The clamp 5 is a concave fan shape, which can effectively support the posterior wall mesentery of the anastomosis and make it open. The movement of the guide rod 12 in the hollow tube 1 allows the user to control the opening and closing of the clamp 5.

[0035] Please see the appendix Figure 4 - Appendix Figure 6 The quick-release structure 2 includes a hollow column 206. The bottom of the hollow column 206 is fixedly connected to the inner wall of the pull plate 26. A sliding column 204 is slidably connected to the inner wall of the hollow column 206. A spring 205 is fixedly connected to the bottom end of the sliding column 204. A locking block 201 is fixedly connected to the outer wall of the sliding column 204. A sliding groove 202 is opened on the outer wall of the pull plate 26. A locking groove 203 is opened at the right end of the guide rod 12. The inner wall of the locking groove 203 is slidably connected to the outer wall of the locking block 201. An anti-slip sleeve 21 is fixedly connected to the top end of the sliding column 204.

[0036] Specifically, spring 205 provides an upward elastic force to sliding post 204, allowing sliding post 204 to return to its initial position when sliding along hollow post 206 under external force. The inner wall of slot 203 is slidably connected to the outer wall of block 201, allowing it to switch between engaged and disengaged states by pressing sliding post 204. Anti-slip sleeve 21 helps the user press sliding post 204 to prevent it from slipping off due to sweat.

[0037] Please see the appendix Figure 2 - Appendix Figure 4 A nameplate 20 is fixedly connected to the front side of the handle 4. The clamp 5 is in the shape of a concave fan. A collar 25 is fixedly connected to the bottom of the handle 4. A hook 23 is fixedly connected to the outer wall of the collar 25. Multiple anti-slip textures 19 are opened on the outer wall of the adjusting sleeve 3. The inner wall of the adjusting sleeve 3 is threadedly connected to the outer wall of the hollow tube 1. An anti-slip pad 24 is fixedly connected to the inner wall of the collar 25. The anti-slip pad 24 is made of rubber.

[0038] Specifically, the nameplate 20 helps users identify the production time and materials used in the production of the sausage depressor. The anti-slip texture 19 helps users increase friction to prevent slippage when adjusting the rotating sleeve 3, thus improving the user experience. The bottom of the handle 4 is fixedly connected to a second collar 25, which works in conjunction with the first collar 22 to provide a fulcrum for the user to press the rotating handle 18. A hook 23 is fixedly connected to its outer wall, allowing the sausage depressor to be hung up and stored when not in use.

[0039] Working principle: When the intestinal clamp is needed, first press the rotating handle 18 to rotate the pull plate 26, thereby pulling the guide rod 12 to move backward, thereby pulling the rotating shaft 8 to rotate, causing the first connecting rod 10 and the second connecting rod 11 to rotate along the rotating shaft 7, causing the two rotating disks 9 to rotate around the rotating shaft 6, thereby closing the clamp 5. At the same time, rotate the adjusting sleeve 3 to adjust its position on the hollow tube 1, thereby adjusting the position of the limiting ring 16, causing the spring 17 to move forward, thereby advancing the position where the limiting ring 13 and the spring 17 meet, extending the hollow tube 1 into the appropriate position. Release the rotating handle 18, and the spring 17 will move the limiting ring 13 forward, causing the guide rod 12 to move forward, thereby pushing out the clamp 5 and causing the rotating disks 9 to rotate, thereby opening the clamp 5 to the outside.

[0040] When the guide rod 12 needs to be cleaned, the sliding column 204 is pressed down to move the locking block 201 downward, thereby disengaging the locking groove 203 from the locking block 201 and pulling out the guide rod 12. After cleaning, the guide rod 12 is inserted along the sliding groove 202. The chamfer on the right end of the guide rod 12 fits against the locking block 201, causing it to move downward and driving the sliding column 204 to press the hollow column 206 downward. When the locking block 201 and the locking groove 203 are in a position where they can engage, the hollow column 206 moves the sliding column 204 and the locking block 201 upward, thereby locking the mechanism.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
