Abstract
Description
Technical Field
[0001] This application relates to the field of medical device technology, specifically to a gastrointestinal anastomosis positioning device. Background Technology
[0002] The gastrointestinal anastomosis device is a core medical instrument used in gastrointestinal surgery to achieve digestive tract reconstruction. It replaces traditional manual suturing with mechanical suturing or staples, efficiently completing the anastomosis and cutting of gastrointestinal tissues. This device enables rapid and precise anastomosis during surgery, effectively shortening operation time, reducing the risk of tissue infection, and improving surgical efficiency and safety.
[0003] Currently, the gastrointestinal anastomosis devices used in clinical practice mainly rely on manual operation by medical staff. During long-term surgery, the hands of medical staff are prone to fatigue, which leads to a decrease in the positioning accuracy of the anastomosis device and increases the surgical risk.
[0004] To address the drawbacks of handheld operation, some gastrointestinal anastomosis device fixation techniques have been developed. However, these devices generally suffer from simplistic structural designs and poor flexibility. Specifically, their fixation angle and position are difficult to adjust flexibly according to the anatomical structure of the surgical site, the surgical approach, and the surgeon's operating habits. Repeated disassembly and re-fixation are often required during surgery, which not only wastes surgical time but may also affect instrument stability and increase the risk of tissue damage due to frequent adjustments. Furthermore, some devices lack precise positioning and reliable locking mechanisms during adjustment, leading to angular displacement or loosening of the gastrointestinal anastomosis device during surgery, failing to meet the dual requirements of instrument stability and flexibility in complex gastrointestinal surgeries. Therefore, there is an urgent need for a gastrointestinal anastomosis device positioning device that can balance operational flexibility and positioning stability to improve the convenience and safety of surgical procedures. Summary of the Invention
[0005] In view of this, this application provides a gastrointestinal anastomosis device positioning device, mainly used to solve the problems of poor flexibility and positioning stability of gastrointestinal anastomosis device positioning devices.
[0006] To address the aforementioned technical problems, this application provides a gastrointestinal anastomosis device positioning apparatus, comprising a base and a bottom plate. A first screw threadedly connected to the base is mounted on the bottom plate, and a first turntable is mounted at the bottom end of the first screw. A side rod is mounted on the bottom plate. A sleeve plate is hinged to the base, and a support rod is fitted inside the sleeve plate. A second screw is threadedly connected to one end of the sleeve plate, and a second turntable is mounted on the second screw. The end of the second screw abuts against the support rod. A connecting plate is mounted above the support rod, and a clamping component for fixing the gastrointestinal anastomosis device is mounted on the connecting plate. An angle adjustment assembly is provided between the support rod and the connecting plate, allowing for flexible adjustment and fixing of the connecting plate according to usage requirements.
[0007] By adopting the above technical solution, this gastrointestinal anastomosis device positioning device achieves flexible and precise positioning through multi-component collaborative design. The base and bottom plate are connected by a first screw thread, which can quickly and stably fix the device in the designated position. The sleeve plate is hinged to the base and has a support rod inside. The extension and retraction of the support rod and the fixation of its position are controlled by a second screw in conjunction with a second turntable. The clamping component of the connecting plate above the support rod is used to fix the gastrointestinal anastomosis device. The angle adjustment component between the support rod and the connecting plate can flexibly adjust and lock the angle as needed. The whole device not only meets the operation requirements of multiple angles and positions during surgery, but also ensures the stability of positioning through the locking structure. It effectively solves the problems of poor flexibility and inconvenience of traditional devices and reduces the operating burden of medical staff.
[0008] Optionally, there are two sets of clamping members, which are symmetrically arranged on the top of the connecting plate.
[0009] By adopting the above technical solution, the two sets of clamping components can clamp different positions of the gastrointestinal anastomosis device, making the force more uniform and improving its stability during use.
[0010] Optionally, a moving groove is provided in the middle of the connecting plate, a moving block is slidably connected inside the moving groove, and a pull rod that can simultaneously open the clamping parts is rotatably connected in the middle of the moving block.
[0011] By adopting the above technical solution, the stability of the gastrointestinal anastomosis device is ensured while the clamping parts can open simultaneously, making it easier for medical staff to fix the gastrointestinal anastomosis device, and making the operation more convenient and labor-saving.
[0012] Optionally, the clamping component includes a movable clamp and a fixed clamp. The connecting plate is provided with a movable groove, and a spring is fixedly connected inside the movable groove. The movable clamp is slidably disposed inside the movable groove, and the movable clamp is fixedly connected to the spring.
[0013] Optionally, the angle adjustment assembly includes a fixed plate with a mounting base on top. A ball is rotatably connected inside the mounting base, and the ball is fixedly connected to the bottom of the connecting plate via a connecting rod.
[0014] By adopting the above technical solution, the connecting plate can be twisted to a suitable angle according to the usage requirements, with a wide adjustment range, convenient and quick operation, and easy promotion and application.
[0015] Optionally, the bottom of the mounting base is provided with a movable cavity, the inside of which is a pressure plate. The internal thread of the support rod is connected to a third screw, and the bottom end of the third screw is provided with a third turntable. The third screw is rotatably connected to the pressure plate.
[0016] By adopting the above technical solution, after the connecting plate is adjusted to a suitable angle, the third turntable is rotated, and the third screw drives the pressure plate to move upward, so that the pressure plate touches the bottom of the ball, increasing the rotational resistance of the ball and ensuring that the gastrointestinal anastomosis device maintains good stability during use.
[0017] Optionally, the pressure plate adopts an arc-shaped structure design that fits into the sphere.
[0018] By adopting the above technical solution, the contact area between the pressure plate and the ball can be increased, thereby increasing the friction between the two and giving it a good limiting effect.
[0019] Optionally, the lower surface of the base and the upper surface of the base plate are provided with multiple arc-shaped grooves of different sizes.
[0020] By adopting the above technical solution, the clamping base can be adapted to connection pipes of different diameters, thereby expanding the application range of the device.
[0021] Optionally, locking bolts are provided at the hinge joint between the base and the sleeve plate.
[0022] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will be combined with the embodiments of this application. Figures 1-6 The technical solutions of the embodiments of this application are clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. All other embodiments obtained by those skilled in the art based on the described embodiments of this application are within the scope of protection of this application.
[0034] Reference Figure 1 and Figure 2 This embodiment provides a gastrointestinal anastomosis device positioning mechanism, including a mounting component, a height adjustment component, an angle adjustment component, and a clamping component. The mounting component is used to stably fix the device to the operating table or other connecting structure; the height adjustment component is disposed on the mounting component and is used to adjust the height of the clamping component; the angle adjustment component is disposed between the clamping component and the height adjustment component and is used to adjust the angle of the clamping component; the clamping component is used to fix the gastrointestinal anastomosis device. Through the coordinated structure of the above components, flexible and precise positioning is achieved. The height and angle of the gastrointestinal anastomosis device can be adjusted according to usage requirements, meeting the operational needs of multiple angles and positions during surgery, while the locking structure ensures positioning stability, thus improving the convenience and safety of surgical operations.
[0035] Among them, reference Figure 1 and Figure 2The mounting components include a base 1, a base plate 11, a first screw 12, a first turntable 121, and side rods 13. The base plate 11 is located below the base 1. The first screw 12 is rotatably mounted on one side of the base plate 11. The first turntable 121 is fixedly connected to the bottom of the first screw 12. The first screw 12 is threadedly connected to the base 1. There are two side rods 13, which are symmetrically distributed on both sides of the first screw 12. The side rods 13 penetrate the base 1 and are used to improve the stability of the base plate 11 during operation.
[0036] Position the base 1 and bottom plate 11 on the upper and lower surfaces of the bed, respectively. Then, rotate the first turntable 121, which drives the first screw 12 to rotate. Under the action of the side rod 13, the first screw 12 drives the bottom plate 11 to move closer to the base 1. With the combined action of the base 1 and bottom plate 11, the device can be stably fixed on the bed.
[0037] Among them, reference Figure 1 , Figure 2 and Figure 3 The height adjustment assembly includes a sleeve plate 2, a support rod 21, a second screw 22, and a second turntable 221. The bottom end of the sleeve plate 2 is hinged to the base 1, and damping is provided between them. The angle of the sleeve plate 2 can also be adjusted according to usage requirements. The support rod 21 is sleeved inside the sleeve plate 2. The second screw 22 is threadedly connected to one side of the sleeve plate 2. The second turntable 221 is fixedly connected to the second screw 22, and the end of the second screw 22 away from the second turntable 221 abuts against the support rod 21. A locking bolt 23 is provided at the hinge between the base 1 and the sleeve plate 2 to increase the stability of the connection between the sleeve plate 2 and the base 1.
[0038] When the angle of the sleeve 2 needs to be adjusted, the angle of the sleeve 2 can be changed by overcoming the damping between the two. Rotating the second turntable 221 causes the second screw 22 to move away from the support rod 21, reducing the friction between them. Then, pulling or pressing the support rod 21 can change the height of the clamping part.
[0039] Among them, reference Figure 2 , Figure 3 , Figure 4 and Figure 6 The angle adjustment assembly includes a fixed plate 3, a mounting base 31, and a ball 32. The fixed plate 3 is located at the top of the support rod 21, the mounting base 31 is located on the fixed plate 3, and the ball 32 is rotatably located inside the mounting base 31. The ball 32 is fixedly connected to the bottom of the connecting plate 4 via a connecting rod.
[0040] By manipulating the connecting plate 4, the angle of the connecting plate 4 can be changed when the ball 32 overcomes the friction with the mounting base 31. This structure allows the connecting plate 4 to be twisted to a suitable angle according to usage requirements, with a wide adjustment range, convenient and quick operation, and easy to promote and apply.
[0041] Additionally, refer to Figure 1 , Figure 5 and Figure 6 The clamping components include a movable clamp 41 and a fixed clamp 42. A movable groove 43 is provided on the connecting plate 4. A spring 44 is fixedly connected inside the movable groove 43. The spring 44 provides a counterforce to the movable clamp 41, causing it to move closer to the fixed clamp 42. The movable clamp 41 is slidably disposed inside the movable groove 43 and is fixedly connected to the spring 44. Both the movable clamp 41 and the fixed clamp 42 are arc-shaped structures adapted to the gastrointestinal anastomosis device.
[0042] Push the movable clamp 41 so that it moves along the movable groove 43 and squeezes the spring 44. At this time, the opening between the movable clamp 41 and the fixed clamp 42 increases. After placing the gastrointestinal anastomosis device between the two, release the movable clamp 41. Under the reaction force of the spring 44, the movable clamp 41 moves towards the fixed clamp 42 and fixes the gastrointestinal anastomosis device.
[0043] Reference Figure 1 , Figure 2 and Figure 5 There are two sets of clamping components, which are symmetrically arranged on the top of the connecting plate 4.
[0044] The two sets of clamping elements can clamp different positions of the gastrointestinal anastomosis device, making the force more even and improving its stability during use.
[0045] Reference Figure 1 and Figure 5 A movable groove 47 is provided in the middle of the connecting plate 4. A movable block 46 is slidably connected inside the movable groove 47. A pull rod 45, which can simultaneously open the clamping member, is rotatably connected in the middle of the movable block 46. The pull rod 45 is located between the movable clamping member 41 and the fixed clamping member 42, and the height of the pull rod 45 is less than the arc-shaped bottom surface of both.
[0046] Pulling the lever 45 along the moving groove 47 simultaneously moves the two movable clamps 41, causing the openings of both clamps to open at the same time. This facilitates the fixation of the gastrointestinal anastomosis device by medical personnel, making the operation more convenient and labor-saving. The lever 45 is rotatably connected between the moving blocks 46. When the two clamps hold the gastrointestinal anastomosis device at different positions, their diameters may also differ. This design does not affect the operation of a single clamp and can maintain a good clamping effect.
[0047] Reference Figure 3 and Figure 4The bottom of the mounting base 31 is provided with a movable cavity 34, and a pressure plate 35 is provided inside the movable cavity 34. The support rod 21 is internally threaded with a third screw 33, and a third turntable 331 is provided at the bottom end of the third screw 33. The third screw 33 is rotatably connected to the pressure plate 35.
[0048] After the connecting plate 4 is adjusted to a suitable angle, the third turntable 331 is rotated, and the third screw 33 drives the pressure plate 35 to move upward, so that the pressure plate 35 touches the bottom of the ball 32, increasing the rotational resistance of the ball 32 and ensuring good stability of the gastrointestinal anastomosis device during use.
[0049] Among them, reference Figure 3 and Figure 4 The pressure plate 35 adopts an arc-shaped structure design that fits into the sphere 32.
[0050] After the pressure plate 35 comes into contact with the ball 32, the contact area between the two can be increased, thereby increasing the friction and giving it a good limiting effect.
[0051] Reference Figure 1 The lower surface of the base 1 and the upper surface of the base plate 11 are provided with multiple arc-shaped grooves 111 of different sizes.
[0052] When the device needs to be fixed to a pipe structure, the corresponding arc groove 111 can be selected according to the pipe size for installation. This allows the mounting component to be compatible with various connecting pipe diameters and fixed to the bed, thereby expanding the device's compatibility and increasing its application range.
[0053] The implementation principle of the gastrointestinal anastomosis positioning device in this application embodiment is as follows:
[0054] The base 1 and the bottom plate 11 are respectively placed on the upper and lower surfaces of the bed. Rotating the first turntable 121 drives the first screw 12 to tighten, causing the bottom plate 11 to move upward and press against the bed. With the guidance of the side rod 13, stable clamping is achieved. The multi-specification arc grooves 111 of the base 1 and the bottom plate 11 can accommodate pipes of different diameters, expanding installation compatibility. When adjusting the height, first adjust the tilt angle of the sleeve plate 2 through the damping hinge structure and fix it with the locking bolt 23. Then rotate the second turntable 221 to loosen the second screw 22 from its clamping position on the support rod 21. Pull the support rod 21 to slide within the sleeve plate 2 to the target height, and then rotate the second turntable 221 in the opposite direction to lock the position.
[0055] The connecting plate 4 is moved to rotate the ball 32 within the mounting base 31 until the connecting plate 4 reaches the required angle. When locked, the third turntable 331 is rotated to push the third screw 33 to move the pressure plate 35 upward. Its arc-shaped structure fits tightly against the bottom surface of the ball 32, increasing the contact area and generating friction to prevent the ball 32 from rotating, thus ensuring the stability of the gastrointestinal anastomosis device angle.
[0056] When the pull rod 45 is pulled, the moving block 46 slides within the moving groove 47, simultaneously pushing open the movable clamp 41 and compressing the spring 44, thus opening the clamping jaws. After the gastrointestinal anastomosis device is placed, the pull rod 45 is released, and the spring 44 returns to its original position, causing the movable clamp 41 to clamp the device, achieving uniform force on both sides. At this point, the positioning of the gastrointestinal anastomosis device is complete.
[0057] Furthermore, it should be noted that, in the description of this application, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0058] The above description is the preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principles described in this application, and these improvements and modifications should also be considered within the scope of protection of this application.
