Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a urological anastomosis device with extended function. Background Technology

[0002] Anastomosing devices are medical instruments used in surgery to replace traditional manual sutures. With the development of modern medical technology, the anastomosing devices currently used in clinical practice have many advantages, such as reliable quality, ease of use, and appropriate tightness and precision. In particular, their advantages of rapid suturing, simple operation, and fewer side effects and surgical complications have made them highly favored and recommended by clinical surgeons both domestically and internationally.

[0003] Currently, anastomosis devices are widely used in urological surgeries. However, the ureteral anatomy varies among patients, with differences in ureteral length, course, and lesion location. If the anastomosis device's lever length is prepared according to general conditions, slight deviations may occur in some special cases, such as patients with longer ureters or those whose ureteral position has changed due to disease. The lever length may not be able to fully reach the anastomosis site, often resulting in difficulties in adjusting the lever length or a limited adjustment range. This can affect the surgical outcome and safety, increasing the difficulty and risk of the procedure. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a urological anastomosis device with an extension function.

[0005] This utility model is achieved using the following technical solution: a urological anastomosis device with an extension function, comprising an anastomosis device body, the anastomosis device body including an anastomosis rod, a rotating block rotatably mounted on one end of the anastomosis rod, a sliding hole penetrating through the anastomosis rod at one end, a pull rod slidably disposed inside the sliding hole, a threaded hole being provided at one end of the rotating block that fits against the anastomosis rod, a first threaded post being fixedly mounted at one end of the pull rod passing through the sliding hole, the first threaded post being located inside the threaded hole and threadedly engaged with the rotating block, an anastomosis head being fixedly mounted at the other end of the pull rod passing through the sliding hole, an extension component being provided on one side of the rotating block that can extend the pull rod when needed, a limiting component being provided on the extension component that can restrict the position of the extension component, an extension hole being provided at the end of the rotating block away from the anastomosis rod, the extension hole communicating with the threaded hole, the extension component including a connecting post disposed inside the extension hole, a second threaded post being fixedly mounted at one end of the connecting post, and the other end of the connecting post extending into the threaded hole and fitting against the first threaded post.

[0006] Through the above technical solution, the extension component allows the length of the pull rod to be extended according to the actual surgical needs, thereby better adapting to the physiological structure of different patients, making it easier for doctors to accurately operate the anastomosis head to reach the site that needs to be anastomosed during surgery, and improving the adaptability and operability of the surgery.

[0007] As a further improvement to the above scheme, the connecting post and the second threaded post have the same diameter, and the diameter of the connecting post is smaller than the diameter of the first threaded post.

[0008] Through the above technical solution, this size design allows the connecting post to move smoothly in the extension hole and the threaded hole, while ensuring the stable fit between the first threaded post and the rotating block, thus ensuring the smoothness and reliability of the extension operation.

[0009] As a further improvement to the above solution, a fixing groove is provided at the connection between the threaded hole and the extension hole. A plurality of first limiting plates arranged in a ring array are fixedly installed at one end of the first threaded post. A first limiting block is fixedly installed on one side of each first limiting plate. Each first limiting block is arranged in an inclined position. A plurality of first fixing holes arranged in a ring array are provided on the cylindrical surface of the connecting post. Each first limiting block is located inside an adjacent first fixing hole.

[0010] Through the above technical solution, the cooperation of the fixing groove, the first limiting plate, the first limiting block and the first fixing port can initially fix the connecting column when the extension component is in contact with the first threaded column.

[0011] As a further improvement to the above solution, a fixing ring is fixedly sleeved on the anastomosis rod, and the limiting component includes two fixing rods symmetrically arranged on one side of the fixing ring. A rubber threaded ring is provided between the two fixing rods, and the rubber threaded ring is threadedly sleeved on the second threaded post.

[0012] Through the above technical solution, the setting of the limiting component can further restrict the position of the extended component. The position of the extended component can be controlled by the threaded engagement between the rubber threaded ring and the second threaded post.

[0013] As a further improvement to the above solution, the top of the fixing ring is symmetrically provided with insertion slots, and one end of each of the two fixing rods is fixedly installed with an insertion block disposed inside the adjacent insertion slot. The two sides of the fixing ring are symmetrically fixedly installed with second limiting plates, and one side of each of the two second limiting plates is fixedly installed with a second limiting block. One side of each of the two second limiting blocks is inclined, and one side of each of the two insertion blocks is provided with a second fixing opening. One side of each second limiting block penetrates the fixing ring and extends into the interior of the adjacent second fixing opening.

[0014] Through the above technical solution, the cooperation of the insertion slot, insertion block, second limiting plate, second limiting block and second fixing port further enhances the fixing effect of the limiting component, making the rubber threaded ring more stable when controlling the extension component.

[0015] As a further improvement to the above solution, a sliding groove is provided on the cylindrical surface of the rubber threaded ring, and a sliding block is fixedly installed at the other end of each of the two fixed rods. Both sliding blocks slide in cooperation with the rubber threaded ring through the sliding groove.

[0016] The above technical solution enables the rubber threaded ring to rotate on the second threaded post by setting up the sliding groove and sliding block.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention, by incorporating an extension component and a limiting component, allows for flexible adjustment of the pull rod length of the urological anastomosis device according to actual surgical needs. This design effectively solves the problems of inconvenient or limited adjustment range of the pull rod length in existing devices, better adapting to the physiological structures of different patients, improving the accuracy and convenience of anastomosis operations during surgery, reducing surgical difficulty and risks, and ensuring the effectiveness and safety of the surgery.

Detailed Implementation

[0025] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] Please combine Figures 1-4 This embodiment of a urological anastomosis device with an extension function includes an anastomosis device body, which includes an anastomosis rod 101. A rotating block 102 is rotatably mounted on one end of the anastomosis rod 101. A sliding hole is opened through the anastomosis rod 101 at one end. A pull rod 103 is slidably disposed inside the sliding hole. A threaded hole is opened at one end of the rotating block 102 that is in contact with the anastomosis rod 101. A first threaded post 104 is fixedly mounted on one end of the pull rod 103 through the sliding hole. The first threaded post 104 is located inside the threaded hole and is threadedly engaged with the rotating block 102. An anastomosis head 105 is fixedly mounted on the other end of the pull rod 103 through the sliding hole. An extension component is provided on one side of the rotating block 102, which can extend the pull rod 103 when needed. A limiting component is provided on the extension component, which can limit the position of the extension component.

[0027] The rotating block 102 has an extension hole at one end away from the matching rod 101. The extension hole is connected to the threaded hole. The extension assembly includes a connecting post 201 disposed inside the extension hole. A second threaded post 202 is fixedly installed at one end of the connecting post 201. The other end of the connecting post 201 extends into the threaded hole and fits against the first threaded post 104. The diameters of the connecting post 201 and the second threaded post 202 are the same, and the diameter of the connecting post 201 is smaller than the diameter of the first threaded post 104.

[0028] The extension component allows the length of the pull rod 103 to be extended according to the actual surgical needs, thereby better adapting to the physiological structure of different patients and facilitating the surgeon to accurately operate the anastomosis head 105 to reach the site requiring anastomosis during surgery, thus improving the adaptability and operability of the surgery.

[0029] A fixing groove 4 is provided at the connection between the threaded hole and the extension hole. A plurality of first limiting plates 5 arranged in a ring array are fixedly installed at one end of the first threaded post 104. A first limiting block 6 is fixedly installed on one side of each first limiting plate 5. Each first limiting block 6 is arranged in an inclined shape. A plurality of first fixing holes arranged in a ring array are provided on the cylindrical surface of the connecting post 201. Each first limiting block 6 is located inside the adjacent first fixing hole.

[0030] The cooperation of the fixing groove 4, the first limiting plate 5, the first limiting block 6 and the first fixing port can initially fix the connecting post 201 when the extension component is attached to the first threaded post 104.

[0031] A fixing ring 7 is fixedly sleeved on the anastomosis rod 101. The limiting component includes two fixing rods 301 symmetrically arranged on one side of the fixing ring 7. A rubber threaded ring 302 is provided between the two fixing rods 301. The rubber threaded ring 302 is threadedly sleeved on the second threaded post 202. The setting of the limiting component can further limit the position of the extended component. The position of the extended component can be controlled by the threaded engagement between the rubber threaded ring 302 and the second threaded post 202. The top of the fixing ring 7 is symmetrically provided with insertion slots. One end of each of the two fixing rods 301 is fixedly installed inside the adjacent insertion slot. The plug-in block 8 and the fixing ring 7 are symmetrically fixed with second limiting plates 9 on both sides. Each of the two second limiting plates 9 is fixed with a second limiting block 10 on one side. Each of the two second limiting blocks 10 is inclined on one side. Each of the two plug-in blocks 8 has a second fixing port on one side. Each of the two second limiting blocks 10 passes through the fixing ring 7 and extends into the interior of the adjacent second fixing port. The cooperation of the plug-in groove, plug-in block 8, second limiting plate 9, second limiting block 10 and second fixing port further enhances the fixing effect of the limiting component, making the rubber threaded ring 302 more stable when controlling the extension component.

[0032] A sliding groove is provided on the cylindrical surface of the rubber threaded ring 302, and a sliding block 11 is fixedly installed at the other end of each of the two fixed rods 301. Both sliding blocks 11 slide with the rubber threaded ring 302 through the sliding groove.

[0033] The implementation principle of a urological anastomosis device with extension function in this application embodiment is as follows: when it is necessary to adjust the length of the pull rod 103, the length of the second threaded post 202 is selected according to the required adjustment length. After selection, the fixing rod 301 is inserted into the insertion groove of the fixing ring 7. During the insertion process, the second limiting block 10 will be squeezed open by the insertion block 8. When the insertion block 8 moves into place, the second limiting block 10 will be locked into the second fixing port of the insertion block 8.

[0034] In this way, the positions of the fixing rod 301 and the rubber threaded ring 302 will be fixed, and only the rubber threaded ring 302 can rotate. Then, the connecting post 201 is inserted into the extension hole, and multiple first limiting blocks 6 are inserted into the first fixing port to fix the connecting post 201.

[0035] During the insertion process, the rubber threaded ring 302 will be threaded onto the surface of the second threaded post 202. At this time, simply rotating the rotating block 102 will cause the first threaded post 104 to move. The movement of the first threaded post 104 will pull the first limiting plate 5, causing the first limiting block 6 to drive the connecting post 201 to move. The movement of the connecting post 201 will also move the second threaded post 202 together.

[0036] Since the second threaded post 202 is threadedly engaged with the rubber threaded ring 302, when the second threaded post 202 moves, simply rotating the rubber threaded ring 302 will not affect the movement of the second threaded post 202.

[0037] Since the second threaded post 202 was selected to the required length at the beginning, the rubber threaded ring 302 is still threaded onto the second threaded post 202. After the first threaded post 104 is separated from the threaded hole, simply rotating the rubber threaded ring 302 can push the second threaded post 202 to move. This will push the connecting post 201, the first threaded post 104 and the pull rod 103 to move a certain distance, so that the length of the pull rod 103 can be flexibly adjusted according to the actual needs of the surgery.

[0038] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
