Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mechanical engineering technology, and specifically relates to a stapler with an anti-slip design. Background Technology
[0002] Existing staplers often suffer from inaccurate adjustment, stroke rebound, or unstable clamping during adjustment and operation due to the lack of effective anti-slip structures between transmission components. This is particularly problematic under repeated operation or varying force conditions, leading to component slippage and positioning failure, affecting the device's response accuracy and reliability. Furthermore, some stapler control mechanisms lack guide limit and automatic reset functions, resulting in poor operating feel and low efficiency.
[0003] In the existing technology, traditional anastomosis device control mechanisms mostly rely on manual push rods or simple gear transmission mechanisms. When adjusting the stroke, problems such as slippage, retraction, or inaccurate positioning are prone to occur. Especially when precise control is required, the lack of an effective anti-slip locking mechanism leads to unstable operation. Although some devices have certain adjustment functions, due to their complex structure and difficulty in resetting, the clamping components are also prone to relative slippage during use, affecting the reliability and accuracy of power transmission.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0016] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0017] Example Reference Figures 1-4 This is an embodiment of the present invention, which provides a stapler with an anti-slip design, comprising: Anastomosis device body 100, used to support and integrate the functional components of the anastomosis device; The control mechanism 200 includes an adjustment component 201, a driven component 202, and an anti-slip component 203; The adjustment assembly 201 includes an adjustment knob 2011, a gear 2012, and a slider 2013. The adjustment knob 2011 is rotatably mounted on the anastomosis device body 100. The gear 2012 is coaxially connected to the adjustment knob 2011 and rotates with it. The slider 2013 is provided with a rack structure that meshes with the gear 2012, and is used to move in a linear direction under the drive of the gear 2012 to adjust the operating stroke of the anastomosis device. Driven component 202 includes spring 2021, pull block 2022 and clamping block 2023. One end of spring 2021 is connected to the inside of stapler body 100 and the other end is connected to pull block 2022 to provide reset elastic force. Pull block 2022 is linked with slider 2013. Clamping block 2023 is provided on pull block 2022 and is used to clamp or drive the internal actuator of stapler during operation. The anti-slip component 203 includes an anti-slip ratchet 2031 and a guide block 2032. The anti-slip ratchet 2031 is provided on the side wall of the slider 2013, and multiple tooth-shaped structures are spaced apart along the moving direction. The guide block 2032 is fixed inside the stapler body 100 and is provided with locking teeth that cooperate with the anti-slip ratchet 2031 to achieve one-way locking during the forward movement of the slider 2013 and prevent it from retracting when subjected to force.
[0018] Specifically, the adjustment knob 2011 has an anti-slip texture or raised structure on its outer periphery, which makes it easier for the operator to apply force to rotate it and improves the stability of operation during the adjustment process.
[0019] It should be noted that the anti-slip texture or raised structure on the outer periphery of the adjustment knob 2011 can significantly increase the friction between the fingers and the knob, making it easier and more stable for the operator to make adjustments. It is especially suitable for surgical environments where sterile gloves are worn, effectively improving the comfort and control precision of human-computer interaction.
[0020] Specifically, a guide groove and guide rib are provided between the slider 2013 and the anastomosis device body 100 to limit the movement trajectory of the slider 2013, ensure that it moves smoothly in a predetermined direction, and avoid deviation or jamming.
[0021] It should be noted that the guide groove and guide rib structure provided between the slider 2013 and the anastomosis device body 100 can accurately guide the movement of the slider, restrict its degree of freedom, and ensure that it moves smoothly only along a predetermined straight line, avoiding deflection, jamming or wear caused by uneven force or assembly errors, thereby improving the reliability of the transmission and the service life of the device.
[0022] Specifically, the inner side of the clamping block 2023 is provided with an elastic pad or anti-slip texture, which can enhance the friction between the clamped part and prevent relative slippage during the driving process.
[0023] It should be noted that the elastic pad or anti-slip texture provided on the inner side of the clamping block 2023 can provide a buffering and friction-enhancing effect during clamping, which can not only prevent damage to the surface of the clamped part, but also effectively improve the clamping stability, avoid slippage or displacement during power transmission, and ensure the continuity and safety of operation.
[0024] Specifically, the anti-slip ratchet 2031 and the guide block 2032 have a one-way helical tooth structure, which only allows the slider 2013 to move forward. When subjected to a reverse force, it automatically locks, effectively preventing accidental retreat or rebound.
[0025] It should be noted that the anti-slip ratchet 2031 and the guide block 2032 adopt a one-way helical tooth design. When the slider 2013 moves forward, the ratchet can smoothly slide over the locking tooth to achieve step adjustment. Once subjected to a reverse force, the ratchet and the locking tooth immediately bite and lock, preventing the slider from retracting, thereby achieving a reliable one-way anti-slip locking function and preventing the adjusted position from being lost due to external force or misoperation.
[0026] Specifically, spring 2021 is a compression spring or torsion spring, installed on the reset path of pull block 2022. After the operation is completed, it automatically drives slider 2013 and clamp block 2023 back to their original positions, facilitating the next operation.
[0027] It should be noted that the spring 2021, as a reset element, can drive the pull block 2022 back to its original position by its own elastic force after the stapler completes one operation stroke. This, in turn, drives the slider 2013 and the clamping block 2023 back to their initial positions, thereby realizing the automatic reset function, simplifying the operation process, improving the efficiency of equipment use and the consistency of repetitive operations.
[0028] In use, the operator first holds the stapler body 100 and adjusts the instrument to the required surgical position. When it is necessary to adjust the operating stroke or clamping force of the stapler, the operator rotates the adjustment knob 2011 with their fingers. The anti-slip texture or raised structure on its outer periphery facilitates stable force application even when wearing gloves. The adjustment knob 2011 drives the coaxially connected gear 2012 to rotate synchronously. The gear 2012 meshes with the rack structure on the slider 2013, thereby driving the slider 2013 to move smoothly forward in a straight line. The movement trajectory of the slider 2013 is precisely defined by the guide groove and guide rib structure between it and the stapler body 100 to prevent deviation or jamming. As the slider 2013 moves forward, its linked pull block 2022 moves synchronously, thereby driving the clamping block 2023 to clamp or... The inner side of the clamping block 2023 is provided with an elastic pad or anti-slip texture, which can effectively increase friction and prevent relative sliding during the driving process, ensuring stable and reliable power transmission. During the forward movement of the slider 2013, the anti-slip ratchet 2031 on its side wall slides one by one over the locking teeth on the guide block 2032 fixed in the anastomosis device body 100, realizing step-by-step adjustment. When the external force causes the slider to tend to retract, the anti-slip ratchet 2031 with the one-way helical tooth structure immediately engages and locks with the locking teeth to prevent accidental retraction and ensure the stability of the adjusted position. After completing one anastomosis operation, the operating force is released, and the spring 2021 recovers its deformation after stretching or compression, providing a reset elastic force, which drives the pull block 2022, slider 2013 and clamping block 2023 to automatically return to the initial state, preparing for the next operation.
[0029] In summary, by setting up a coordinated structure of adjustment component 201, driven component 202 and anti-slip component 203, precise adjustment and stable transmission of the anastomosis device's operating stroke are achieved. The anti-slip design of adjustment knob 2011 improves operability. The guiding cooperation between slider 2013 and anastomosis device body 100 ensures smooth movement. The elastic pad or anti-slip texture on the inner side of clamping block 2023 enhances clamping reliability. Anti-slip ratchet 2031 and guide block 2032 form a one-way locking mechanism to effectively prevent force-induced backlash. Spring 2021 provides reset force to achieve automatic return, thus improving the anastomosis device's operational stability and ease of use.
