[0021] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The utility model embodiment provides a hemorrhoid ligation kissing device, such as Figure 1-4 As shown, the hemorrhoid ligation kissing device comprises: a ligation device body 1, the ligation device body 1 comprises a negative pressure interface 2 fixedly mounted on the bottom of the ligation device body 1 and a ligation device barrel 3 fixedly mounted on the ligation side of the ligation device body 1; a mounting sleeve 4, the mounting sleeve 4 is threadedly mounted on the ligation side of the ligation device barrel 3; a plurality of push-wire sleeves 5, the push-wire sleeves 5 are slidably mounted on the mounting sleeve 4; a plurality of tightening wire tubes 6, the tightening wire tubes 6 can be buckled on the push-wire sleeves 5 and are in sliding contact with the push-wire sleeves 5; a plurality of elastic wires 7, the elastic wires 7 are arranged on the tightening wire tubes 6 , the coil of the elastic wire 7 can be sleeved on the push wire sleeve 5 or the hemorrhoid tissue; a stabilizing mechanism, the stabilizing mechanism is arranged on the mounting sleeve 4, and the stabilizing mechanism is used to stabilize the position of the push wire sleeve 5; a limiting mechanism, the limiting mechanism is arranged on the mounting sleeve 4, and the limiting mechanism is used to limit the displacement of the push wire sleeve 5; a pushing wire mechanism, the pushing wire mechanism is arranged on the pushing wire sleeve 5, and the pushing wire mechanism is used to push out the coil of the elastic wire 7; a tightening wire mechanism, the tightening wire mechanism is arranged on the mounting sleeve 4, and the tightening wire mechanism is used to tighten the coil of the elastic wire 7.

[0023] In this embodiment, first, the ligation device body 1 serves as the basis of the entire device, and the negative pressure interface 2 at the bottom and the ligation device barrel 3 at the ligation side respectively realize the basic functions of negative pressure suction and ligation operation. The negative pressure interface 2 can suck the hemorrhoidal tissue into the ligation device barrel 3 by connecting the negative pressure device, so as to prepare for the subsequent ligation operation.

[0024] Secondly, the installation sleeve 4, the push-wire sleeve 5, the tightening wire tube 6 and the elastic wire 7 constitute the core part of the ligation operation. The installation sleeve 4 is installed on the barrel 3 of the ligation device, and provides a track for the installation and sliding of the push-wire sleeve 5 and the tightening wire tube 6. The push-wire sleeve 5 slides on the installation sleeve 4, and pushes out the coil of the elastic wire 7 through the push-wire mechanism thereon, so that it is sleeved on the hemorrhoidal tissue. The tightening wire tube 6 can be buckled on the push-wire sleeve 5 and is in sliding contact with the push-wire sleeve 5, thereby ensuring the stability of the elastic wire 7 during the pushing and tightening process. The elastic wire 7 is the actual executor of the ligation of the hemorrhoidal tissue, and its coil can tightly wrap around the hemorrhoidal tissue to achieve the ligation effect.

[0025] In addition, the setting of the stabilizing mechanism is a highlight of this patent. The stabilizing mechanism is installed on the mounting sleeve 4 and is used to stabilize the position of the wire pushing sleeve 5. In the process of pushing out and tightening the elastic wire 7, the stabilizing mechanism can ensure that the wire pushing sleeve 5 will not move due to external forces, thereby greatly improving the stability and accuracy of the operation.

[0026] The limiting mechanism is used to limit the displacement of the wire pushing sleeve 5 to prevent it from exceeding a preset range during the sliding process, thereby further ensuring the accuracy and safety of the operation.

[0027] Finally, the arrangement of the wire pushing mechanism and the wire tightening mechanism makes it more convenient to push out and tighten the elastic wire 7. The wire pushing mechanism can easily push out the coil of the elastic wire 7, while the wire tightening mechanism can quickly tighten the coil to achieve rapid ligation of hemorrhoid tissue.

[0028] In a further preferred embodiment of the utility model, the stabilizing mechanism includes a driving groove 8 opened on both sides of the mounting sleeve 4, a driving rod 9 is rotatably installed in the driving groove 8, a driving block 10 is threadedly installed on the driving rod 9, and one side of the driving block 10 extending out of the driving groove 8 can contact the push wire sleeve 5, a driving motor 11 is fixedly installed in the driving groove 8, and the output shaft of the driving motor 11 is fixedly connected to the driving rod 9.

[0029] In this embodiment, first, the driving groove 8 is provided on both sides of the mounting sleeve 4, providing installation space for the driving rod 9. The driving rod 9 is rotatably installed in the driving groove 8, and the thread structure thereon matches the driving block 10. The side of the driving block 10 extending out of the driving groove 8 contacts the wire pushing sleeve 5, so when the driving rod 9 rotates, the driving block 10 moves in the driving groove 8 due to the action of the thread, and then contacts the wire pushing sleeve 5 and applies pressure thereto, thereby stabilizing the position of the wire pushing sleeve 5.

[0030] Secondly, the introduction of the drive motor 11 makes the work of the stabilizing mechanism more automated and precise. The drive motor 11 is installed in the drive slot 8, and its output shaft is fixedly connected to the drive rod 9, so the rotation of the drive rod 9 can be driven by controlling the operation of the drive motor 11, thereby achieving precise control of the position of the push wire sleeve 5.

[0031] Combined with the use of the above-mentioned claims, the design of this stabilizing mechanism greatly improves the stability and accuracy of the ligation operation. In the process of pushing out and tightening the elastic wire 7, even if it is affected by external forces, the wire pushing sleeve 5 can maintain a stable position, thereby ensuring that the elastic wire 7 can be accurately and quickly set on the hemorrhoid tissue. This not only improves the operating efficiency and reduces the operating difficulty of medical staff, but also makes the entire ligation process safer and more reliable.

[0032] In a further preferred embodiment of the utility model, the limiting mechanism includes limiting grooves 12 opened on both sides of the tying side of the push wire sleeve 5, and compression grooves 13 are opened on both sides of the tying side of the mounting sleeve 4. A compression rod 14 is fixedly installed in the compression groove 13, and a limiting frame 15 is slidably sleeved on the compression rod 14. The limiting frame 15 can extend into the limiting groove 12, and a first spring 16 is sleeved on the compression rod 14. The two ends of the first spring 16 are respectively fixedly connected to the inner wall of the compression groove 13 and the limiting frame 15.

[0033] In this embodiment, first, the limiting groove 12 is provided on both sides of the tying side of the push wire sleeve 5, providing space for the limiting frame 15 to enter. The compression groove 13 is provided on both sides of the tying side of the installation sleeve 4, and a compression rod 14 is fixedly installed inside. The limiting frame 15 is slidably sleeved on the compression rod 14, and the limiting frame 15 can slide along the compression rod 14 and can extend into the limiting groove 12 under certain conditions.

[0034] Secondly, the introduction of the first spring 16 makes the work of the limiting mechanism more flexible and reliable. The first spring 16 is sleeved on the compression rod 14, and its two ends are respectively fixedly connected to the inner wall of the compression groove 13 and the limiting frame 15. When the push wire sleeve 5 slides on the installation sleeve 4, the limiting frame 15 will be squeezed by the push wire sleeve 5 and slide along the compression rod 14 to the inside of the compression groove 13. At this time, the first spring 16 will be compressed and store elastic potential energy. When the push wire sleeve 5 slides to the preset position, the limiting frame 15 will pop out under the elastic force of the first spring 16 and extend into the limiting groove 12, thereby limiting the displacement of the push wire sleeve 5.

[0035] The design of the limiting mechanism not only ensures the stability of the push wire sleeve 5 during the sliding process, but also prevents it from exceeding the preset range due to external forces during operation. At the same time, due to the coordinated use of the limiting frame 15 and the limiting groove 12, the displacement of the push wire sleeve 5 is restricted more accurately and reliably.

[0036] Combined with the use of the above-mentioned claims, the design of this limiting mechanism improves the accuracy and safety of the ligation operation. In the process of pushing out and tightening the elastic wire 7, the wire pushing sleeve 5 can maintain a stable position and is automatically limited by the limiting mechanism when reaching the preset position, thereby ensuring that the elastic wire 7 can be accurately and quickly sleeved on the hemorrhoid tissue. This not only improves the operating efficiency, but also reduces the risks caused by improper operation.

[0037] In a further preferred embodiment of the utility model, the wire pushing mechanism includes a guide groove 17 opened on both sides of the rear side of the wire pushing sleeve 5, a guide frame 18 is slidably provided in the guide groove 17, a wire pushing ring 19 is slidably provided on the wire pushing sleeve 5, the wire pushing ring 19 can contact the elastic wire 7, the guide frame 18 extends to one side of the wire pushing sleeve 5 and is fixedly connected to the wire pushing ring 19, a second spring 20 is sleeved on the guide frame 18, and the two sides of the second spring 20 are respectively fixedly connected to the inner wall of the guide groove 17 and the expanded part of the guide frame 18.

[0038] In this embodiment, first, the guide groove 17 is provided on both sides of the rear side of the wire pushing sleeve 5, providing a sliding track for the guide frame 18. The guide frame 18 slides in the guide groove 17, and one side of the guide frame 18 extends to the tying side of the wire pushing sleeve 5 and is fixedly connected to the wire pushing ring 19. The wire pushing ring 19 can slide on the wire pushing sleeve 5 and can contact the elastic wire 7.

[0039] Secondly, the introduction of the second spring 20 makes the push-out of the wire-pushing ring 19 more flexible and reliable. The second spring 20 is sleeved on the guide frame 18, and its two sides are fixedly connected to the inner wall of the guide groove 17 and the bulge of the guide frame 18 respectively. When it is necessary to push out the coil of the elastic wire 7, it is only necessary to apply a certain thrust to the wire-pushing ring 19 so that it overcomes the elastic force of the second spring 20 and slides forward along the guide groove 17. In this process, the wire-pushing ring 19 will push out the coil of the elastic wire 7 in contact with it, so as to achieve the purpose of being sleeved on the hemorrhoid tissue. When the thrust disappears, the elastic force of the second spring 20 will cause the guide frame 18 and the wire-pushing ring 19 to automatically return to the initial position, so as to prepare for the next wire-pushing operation.

[0040] The design of this wire pushing mechanism not only simplifies the operation of pushing out the coil of the elastic wire 7, but also improves the stability and accuracy of the operation. Due to the guiding effect of the guide groove 17 and the guide frame 18, the wire pushing ring 19 can slide along the preset track, ensuring that the coil of the elastic wire 7 can be pushed out accurately and quickly. At the same time, the introduction of the second spring 20 makes the pushing out and returning of the wire pushing ring 19 more automatic and convenient.

[0041] Combined with the use of the above-mentioned claims, the design of this wire pushing mechanism improves the efficiency and quality of the ligation operation. During the operation, the doctor only needs to apply a pushing force to the wire pushing ring 19 to push out the elastic wire 7 coil, which greatly simplifies the operation steps. At the same time, due to the improvement of the stability and accuracy of the operation, the risk caused by improper operation is also reduced.

[0042] In a further preferred embodiment of the utility model, the tensioning mechanism includes a support groove 21 provided on the guide frame 18, a support rod 22 is rotatably installed in the support groove 21, a support frame 23 is threadedly installed on the support rod 22, and the side of the elastic line 7 away from the tying side can be sleeved on the support frame 23, a support motor 24 is fixedly installed on one side of the support groove 21, and the output shaft of the support motor 24 is fixedly connected to the support rod 22.

[0043] In this embodiment, first, the support groove 21 is provided on the guide frame 18, providing an installation space for the support rod 22. The support rod 22 is rotatably installed in the support groove 21, and the thread structure thereon matches the support frame 23. The side of the elastic wire 7 away from the tying side can be sleeved on the support frame 23, so when the support rod 22 rotates, the support frame 23 will move in the support groove 21 due to the effect of the thread, and then apply tension to the coil of the elastic wire 7 sleeved thereon, achieving a tightening effect.

[0044] Secondly, the introduction of the support motor 24 makes the work of the tensioning mechanism more automated and precise. The support motor 24 is installed on one side of the support slot 21, and its output shaft is fixedly connected to the support rod 22, so the rotation of the support rod 22 can be driven by controlling the operation of the support motor 24, thereby achieving precise tensioning of the coil of the elastic wire 7.

[0045] The design of this tightening mechanism not only simplifies the tightening operation of the elastic wire 7 coil, but also improves the stability and accuracy of the operation. Due to the precise control of the support motor 24, the doctor can adjust the tightness of the elastic wire 7 coil according to actual needs to adapt to hemorrhoid tissues of different sizes and shapes. At the same time, due to the threaded matching of the support rod 22 and the support frame 23, the tightening process is more stable and reliable, avoiding operational errors caused by excessive or insufficient tension.

[0046] Combined with the use of the above-mentioned claims, the design of this tightening mechanism improves the efficiency and quality of the ligation operation. During the operation, the doctor only needs to control the operation of the support motor 24 to automatically tighten the coil of the elastic wire 7, which greatly simplifies the operation steps. At the same time, due to the improvement of the stability and accuracy of the operation, the risk caused by improper operation is also reduced.

[0047] In a further preferred embodiment of the utility model, a pull rope 25 is fixedly installed on one side of the limit frame 15 located in the compression groove 13, pull grooves 26 are opened on both sides of the mounting sleeve 4, a pull plate 27 is slidably provided in the pull groove 26, one end of the pull rope 25 extending into the pull groove 26 is fixedly connected to the pull plate 27, a pull ring 28 is slidably provided on the barrel 3 of the ligation device, and one side of the two pull plates 27 extending out of the pull groove 26 is fixedly connected to the pull ring 28.

[0048] In this embodiment, first, one end of the pull rope 25 is fixedly mounted on one side of the limit frame 15 located in the compression groove 13, and the other end extends into the pull groove 26 and is fixedly connected to the pull plate 27. The pull groove 26 is provided on both sides of the mounting sleeve 4, providing space for the sliding of the pull plate 27. The pull plate 27 slides in the pull groove 26, and one side thereof extending out of the pull groove 26 is fixedly connected to the pull ring 28. The pull ring 28 is slidably sleeved on the barrel 3 of the ligation device, which is convenient for manual operation by medical personnel.

[0049] In actual use, when it is necessary to remove the used push wire sleeve 5, the medical staff can manually pull the pull ring 28 to slide the pull plate 27 in the pull groove 26. Due to the connection of the pull rope 25, the sliding of the pull plate 27 will drive the limit frame 15 to move in the compression groove 13, thereby changing the relative position of the limit frame 15 and the limit groove 12. When the limit frame 15 is completely removed from the limit groove 12, the push wire sleeve 5 can slide out from the installation sleeve 4; when the limit frame 15 re-enters the limit groove 12, the position of the next push wire sleeve 5 is fixed.

[0050] This design not only simplifies the control operation of the position of the push wire sleeve 5, but also improves the convenience and accuracy of the operation. Medical staff can adjust the position of the limit frame 15 by simply pulling the pull ring 28 without complicated mechanical operations. At the same time, since the transmission mechanism composed of the pull rope 25, the pull groove 26, the pull plate 27 and the pull ring 28 has a simple and reliable structure, the entire operation process is more stable and safe.

[0051] Combined with the use of the above-mentioned claims, the design of this limiting mechanism not only improves the efficiency and accuracy of the ligation operation, but also reduces the workload of medical staff. Medical staff can more easily and conveniently adjust and control the position of the push wire sleeve 5, thereby ensuring the smooth progress of the ligation process.

[0052] In a further preferred embodiment of the present invention, a plurality of fixing sleeves 29 are fixedly mounted on a side of the mounting sleeve 4 away from the tying side, and the rear side of the guide frame 18 can extend into the fixing sleeves 29 and be in sliding contact with the fixing sleeves 29 .

[0053] In this embodiment, first, the fixing sleeve 29 is fixedly mounted on the side of the mounting sleeve 4 away from the tying side, and the number of fixing sleeves 29 can be set according to actual needs. The rear side of the guide frame 18 can extend into the fixing sleeve 29 and slide in contact with the inner wall of the fixing sleeve 29. In this way, when the guide frame 18 slides in the guide groove 17, the fixing sleeve 29 provides a stable support for it, ensuring the smoothness and accuracy of the sliding of the guide frame 18.

[0054] The advantage of this design is that it enhances the overall stability of the wire pushing mechanism. Since the guide frame 18 is a key component of the wire pushing ring 19 and the wire pushing operation, its stability directly affects the accuracy and reliability of the wire pushing operation. By adding a fixing sleeve 29 and slidingly contacting with the rear side of the guide frame 18, the shaking and deviation of the guide frame 18 during the sliding process can be effectively reduced, thereby improving the stability and accuracy of the wire pushing operation.

[0055] In addition, the fixing sleeve 29 also plays a certain guiding role. Since the inner wall of the fixing sleeve 29 is in sliding contact with the rear side of the guide frame 18, it can guide and constrain the sliding direction of the guide frame 18, ensuring that the guide frame 18 always slides along the predetermined track. This helps to avoid deviation or jamming of the guide frame 18 during the sliding process, further improving the smoothness and reliability of the wire pushing operation.

[0056] In summary, compared with the related art, firstly, by optimizing the limiting mechanism, the device can realize accurate control of the position of the wire pushing sleeve 5, ensuring the stability and accuracy of the ligation process. At the same time, the design of the wire pushing mechanism and the wire tightening mechanism makes the pushing and tightening operation of the elastic wire 7 more convenient and automated, thereby improving the operating efficiency.

[0057] Secondly, the device also takes into account the convenience and comfort of use. By adding structures such as the fixing sleeve 29, stable support and guidance of key components are achieved, reducing the difficulty of operation and the workload of medical staff. In addition, the device also adopts energy-saving and environmental protection technology to reduce pollution to the environment.
