Description

Technical Field

[0001] This utility model relates to the field of tightening and locking technology for the lower endoscope thread, specifically a device for tightening and locking the lower endoscope thread. Background Technology

[0002] Surgery, also known as surgery or incision, refers to the process of inserting surgical equipment or instruments into the human body or other biological tissues through the operation of a surgeon or other professionals to remove lesions, change structures, or implant foreign objects by external force. In surgery, hemostatic forceps are usually used to stop bleeding, and sutures are used to close the wound. During the suturing process, the sutures need to be tightened and other operations are required.

[0003] When medical staff tighten sutures during digestive endoscopy, the limited operating space makes the operation very inconvenient and increases the surgical risk. Therefore, a device is needed to tighten and lock sutures during digestive endoscopy. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of the aforementioned background technology by proposing a device for tightening and locking the thread under a digestive endoscope.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a suture tightening and locking device for digestive endoscopy, comprising an outer tube and a release mechanism. An observation perforation is provided in the upper middle part of the outer tube, and a slanted groove is provided at the top of the outer tube. An inner tube is slidably connected inside the outer tube. Two sets of compression blocks are provided at one end of the outer tube. Two sets of connecting blocks are connected to one end of the inner tube via a rotating shaft, and one end of each connecting block is fixedly connected to a compression block. A surgical suture is provided between the compression blocks, and one end of the surgical suture passes through the observation perforation. A first internally threaded rotating component is threadedly connected to the lower middle part of the inner tube. A first rotating ring is connected to the top of the first internally threaded rotating component via a bearing. Fixed grooves are evenly provided on the side of the connecting blocks that are close to each other. A first spring is evenly provided between the connecting blocks, and both ends of the first spring are fixedly connected to the inner wall of the fixed groove. A limit block is fixedly connected to the bottom end of the inner tube.

[0006] Preferably, the chute is funnel-shaped, and the outer wall of the extrusion block is an inclined surface adapted to the chute, so that the extrusion blocks can automatically move closer to each other.

[0007] Preferably, the sides of the extrusion blocks that are close to each other are wavy, and the extrusion blocks interlock with each other to increase friction and facilitate the extrusion blocks to lock the surgical suture.

[0008] Preferably, the release mechanism includes a sliding groove, a receiving groove, a locking groove, a sliding locking block, a second spring, a connecting groove, a stop rod, a second internally threaded rotating component, and a second rotating ring. The inner wall of the inclined groove is symmetrically provided with sliding grooves, and one end of each sliding groove is provided with a locking groove. The lower middle part of each compression block is provided with a receiving groove, and each receiving groove contains a sliding locking block, with one end of each sliding locking block located inside the locking groove. One end of each sliding locking block is fixedly connected to a second spring, and one end of each second spring is fixedly connected to the inner wall of the receiving groove. The inner interior of the outer tube is symmetrically provided with connecting grooves, and the top ends of each connecting groove are connected to the locking groove. A stop rod is slidably connected inside each connecting groove. The lower middle part of the outer tube is threadedly connected to a second internally threaded rotating component, and the top end of the second internally threaded rotating component is connected to a second rotating ring via a bearing. The bottom end of each stop rod is fixedly connected to the top end of the second rotating ring. This mechanism can guide and limit the movement of the compression block, and also facilitates the user's unlocking of the surgical suture.

[0009] Preferably, both the first and second internal threaded rotating parts have uniformly formed anti-slip grooves on their surfaces to increase friction and facilitate user rotation of the first and second internal threaded rotating parts.

[0010] Preferably, one end of each sliding lock block is arc-shaped, and the top end of each abutment rod is arc-shaped, so that the sliding lock block can move easily after the abutment rod abuts against the sliding lock block.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] After the medical staff passes the surgical suture through the squeezing block and observation hole, they rotate the first internal threaded component. This causes the inner tube to pull the squeezing block downwards, clamping the surgical suture. Simultaneously, the squeezing block drives the sliding locking block to slide within the groove. When one end of the sliding locking block is engaged in the locking groove by the second spring, the squeezing block and the surgical suture are locked together, facilitating the locking process for the medical staff. After use, rotating the second internal threaded component moves the abutment rod upwards, abutting against one end of the sliding locking block. The device allows the sliding locking block to move into the groove via a stop rod until one end of the sliding locking block is no longer inside the groove. At this point, the medical staff can rotate the first internal threaded rotating part in the opposite direction to move the inner tube and the squeezing block upward. The two sets of squeezing blocks separate under the action of the first spring, so that the squeezing blocks no longer tighten the surgical suture, making it easier for the medical staff to unlock the surgical suture. This device is not only convenient for medical staff to use in confined spaces, but also can clamp and lock the surgical suture, as well as unlock it, making it easier for medical staff to operate, thereby reducing the risk of surgery and shortening the operation time.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] Please see Figures 1-4 One embodiment provided by this utility model:

[0020] A suture tightening and locking device for digestive endoscopy includes an outer tube 1 and a release mechanism. The upper middle part of the outer tube 1 has an observation perforation 2, and the top end of the outer tube 1 has an inclined groove 3. An inner tube 4 is slidably connected inside the outer tube 1. Two sets of compression blocks 5 are provided at one end of the outer tube 1. Two sets of connecting blocks 6 are connected to one end of the inner tube 4 through a rotating shaft, and one end of each connecting block 6 is fixedly connected to the compression block 5. A surgical suture 7 is provided between the compression blocks 5, and one end of the surgical suture 7 passes through the observation perforation 2. A first internal threaded rotating part 8 is threadedly connected to the lower middle part of the inner tube 4. The top end of the first internal threaded rotating part 8 is connected to a first rotating ring 9 through a bearing. Fixing grooves 10 are evenly provided on the side of the connecting blocks 6 that are close to each other. A first spring 11 is evenly provided between the connecting blocks 6, and both ends of the first spring 11 are fixedly connected to the inner wall of the fixing groove 10. A limit block 21 is fixedly connected to the bottom end of the inner tube 4.

[0021] Furthermore, the release mechanism includes a slide groove 12, a receiving groove 13, a locking groove 14, a sliding locking block 15, a second spring 16, a connecting groove 17, a stop rod 18, a second internal threaded rotating part 19, and a second rotating ring 20. The inclined groove 3 has slide grooves 12 symmetrically formed on its inner wall. Each slide groove 12 has a locking groove 14 at one end. The lower middle part of the pressing block 5 has a receiving groove 13. Each receiving groove 13 has a sliding locking block 15 inside it, and one end of each sliding locking block 15 is located inside the locking groove 14. One end of each sliding locking block 15 is fixedly connected to a second spring 16, and one end of each second spring 16 is... The outer tube 1 is not fixedly connected to the inner wall of the receiving groove 13. The inner wall of the outer tube 1 is symmetrically provided with connecting grooves 17, and the top of each connecting groove 17 is connected to the locking groove 14. The connecting groove 17 is slidably connected with a push rod 18. The middle and lower part of the outer tube 1 is connected to a second internal thread rotating part 19 by a thread. The top of the second internal thread rotating part 19 is connected to a second rotating ring 20 by a bearing. The bottom of the push rod 18 is fixedly connected to the top of the second rotating ring 20. The pressing block 5 drives the sliding locking block 15 to slide inside the sliding groove 12. When one end of the sliding locking block 15 is stuck in the locking groove 14 under the action of the second spring 16, After the internal mechanism of 4 is engaged, the compression block 5 and surgical suture 7 can be locked by the locking groove 14 and the sliding locking block 15, which facilitates the locking work of medical staff and facilitates subsequent work. After the medical staff has finished using it, they rotate the second internal thread rotating part 19. At this time, the second internal thread rotating part 19 and the second rotating ring 20 move upward. The second rotating ring 20 can reduce the friction between the abutment rod 18 and the second internal thread rotating part 19. Rotating the second internal thread rotating part 19 can make the abutment rod 18 move upward and abut against one end of the sliding locking block 15. The abutment rod 18 can make the abutment rod 18 move upward and abut against one end of the sliding locking block 15. The sliding locking block 15 moves into the groove 13 and compresses the second spring 16 until one end of the sliding locking block 15 is no longer inside the groove 14. At this time, the medical staff can rotate the first internal threaded rotating part 8 in the opposite direction to make the inner tube 4 and the squeezing block 5 move upward. The two sets of squeezing blocks 5 separate under the action of the first spring 11, so that the squeezing blocks 5 no longer tighten the surgical suture 7, which makes it convenient for the medical staff to unlock the surgical suture 7. It can guide and limit the movement of the squeezing block 5, and also makes it convenient for the user to unlock the surgical suture 7.

[0022] It should be noted that the inclined groove 3 is funnel-shaped, and the outer wall of the extrusion block 5 is an inclined surface that matches the inclined groove 3, which facilitates the extrusion blocks 5 to automatically approach each other. The side of the extrusion blocks 5 that approaches each other is wavy. The extrusion blocks 5 interlock with each other, increasing the friction and making it easier for the extrusion blocks 5 to lock the surgical suture 7. The surfaces of the first internal thread rotating part 8 and the second internal thread rotating part 19 are evenly provided with anti-slip grooves to increase the friction and make it easier for the user to rotate the first internal thread rotating part 8 and the second internal thread rotating part 19. One end of the sliding locking block 15 is arc-shaped, and the top of the abutment rod 18 is arc-shaped. When the abutment rod 18 abuts against the sliding locking block 15, it is easy for the sliding locking block 15 to move.

[0023] Working principle: After the medical staff passes the surgical suture 7 through the compression block 5 and the observation hole 2, they rotate the first internal thread rotating component 8. At this time, the first internal thread rotating component 8 drives the first rotating ring 9 to move upward until the first rotating ring 9 contacts the bottom end of the outer tube 1. The user continues to rotate the first internal thread rotating component 8. At this time, the first rotating ring 9 can prevent excessive friction between the first internal thread rotating component 8 and the outer tube 1. Since the outer tube 1 restricts the position of the first internal thread rotating component 8 and the first rotating ring 9, the inner tube 4 can move downward, and at the same time, it pulls the compression block 5 downward. After the inner wall of the inclined groove 3 comes into contact with the surface of the extrusion block 5, the two sets of extrusion blocks 5 and the connecting block 6 move closer to each other. The connecting block 6 can compress the first spring 11, while the extrusion block 5 can clamp the surgical suture 7. The extrusion block 5 drives the sliding locking block 15 to slide inside the sliding groove 12. When one end of the sliding locking block 15 is locked inside the locking groove 14 under the action of the second spring 16, the extrusion block 5 and the surgical suture 7 can be locked by the locking groove 14 and the sliding locking block 15, thus facilitating the locking work of medical staff. In the subsequent work of the medical staff, after the medical staff have finished using the equipment, they rotate the second internal thread rotating part 19. At this time, the second internal thread rotating part 19 and the second rotating ring 20 move upward. The second rotating ring 20 can reduce the friction between the abutment rod 18 and the second internal thread rotating part 19. Rotating the second internal thread rotating part 19 can cause the abutment rod 18 to move upward and abut against one end of the sliding locking block 15. The abutment rod 18 can cause the sliding locking block 15 to move into the receiving groove 13. At the same time, the sliding locking block 15 compresses the second spring 16 until one end of the sliding locking block 15 is compressed. When the device is no longer inside the locking groove 14, medical staff can rotate the first internal threaded rotating part 8 in the opposite direction to move the inner tube 4 and the squeezing block 5 upward. The two sets of squeezing blocks 5 separate under the action of the first spring 11, so that the squeezing blocks 5 no longer tighten the surgical suture 7, thus making it easier for medical staff to unlock the surgical suture 7. This device can not only be used by medical staff in a confined space, but also clamp and lock the surgical suture 7, and can also unlock it, which facilitates the operation of medical staff, thereby reducing the risk of surgery and shortening the operation time.
