[0002] Existing endoscopic staplers are widely used in surgery, and their staple cartridge components require frequent replacement. The accuracy of the connection directly affects surgical safety and operational efficiency. Currently, the connection between the staple cartridge and the main unit largely relies on manual alignment, which presents problems such as difficulty in alignment, inaccurate positioning, and insecure locking, especially in confined surgical spaces where ensuring assembly quality is even more challenging. Some auxiliary devices have complex structures and cumbersome operations, making it difficult to achieve quick and stable connections, and they are prone to loosening or jamming after prolonged use.

[0003] In existing technologies, the installation of staple cartridge components in traditional endocavitary staplers often relies on manual docking, which is cumbersome, difficult to align, and has unstable connections. Especially during surgery, the limited field of vision or small operating space can lead to low assembly efficiency, poor stability, and even the risk of staple cartridge loosening or misalignment, affecting surgical safety. In addition, some auxiliary docking devices have complex structures and are inconvenient to disassemble and assemble, making it difficult to achieve rapid replacement and failing to meet the high-frequency and high-precision use requirements of clinical practice.

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 embodiment of the present invention provides a quick docking and stabilizing device for an intracavitary cutting stapler cartridge assembly, comprising: The supporting mechanism 100 is used to support and fix the structure of the entire docking device; The fastener 101 is mounted on the support mechanism 100 and is used to achieve the initial positioning and installation of the staple cartridge assembly; The fastener 101 includes a base 1011 and a fixing block 1012. The base 1011 is connected to the support mechanism 100 and is used to provide an installation platform. The fixing block 1012 is disposed on the base 1011 and is used to clamp and fix the staple cartridge assembly. The docking mechanism 200 includes an extrusion component 201 and a splicing component 202; The compression assembly 201 includes an adjustment handle 2011, a guide rod 2012, and a compression block 2013. The adjustment handle 2011 is rotatably mounted on the bearing mechanism 100. The guide rod 2012 is connected between the adjustment handle 2011 and the compression block 2013 to guide the direction of movement. The compression block 2013 moves towards the splicing assembly 202 under the drive of the adjustment handle 2011 to achieve the compression and locking of the staple cartridge assembly. The splicing assembly 202 includes a fixing sleeve 2021 and a positioning rod 2022. The fixing sleeve 2021 is mounted on the bearing mechanism 100 and is used to accommodate and position the mating end of the staple cartridge assembly. The positioning rod 2022 is located inside the fixing sleeve 2021 and is used to insert into the mating hole of the staple cartridge assembly to achieve precise alignment and quick connection.

[0018] Specifically, the fixing block 1012 is equipped with an elastic clamping structure that can automatically clamp when the staple cartridge assembly is inserted, preventing it from loosening or shifting during the docking process.

[0019] It should be noted that the elastic clamping structure of the fixing block 1012 can be made of spring sheets or elastic metal parts, which can automatically generate clamping force when the staple cartridge assembly is inserted into the installation position on the base 1011 to achieve initial fixation and effectively prevent loosening or displacement caused by vibration or operating force during subsequent docking, thereby improving the stability and safety of docking.

[0020] Specifically, the adjustment lever 2011 drives the compression block 2013 to move via a threaded drive or lever mechanism, thereby achieving rapid compression and release of the staple cartridge assembly and improving operational efficiency.

[0021] It should be noted that the adjustment handle 2011 drives the compression block 2013 to move via a threaded drive or lever mechanism, which not only saves effort in operation but also enables precise control of the clamping force, ensuring that the nail cartridge assembly is firmly locked. At the same time, this structure supports quick release and is easy to disassemble and replace, significantly improving the ease of operation and efficiency of the device.

[0022] Specifically, the guide rod 2012 is equipped with a sliding sleeve, which can ensure that the extrusion block 2013 moves smoothly in a straight line and avoid docking failure or component damage due to off-center loading.

[0023] It should be noted that the guide rod 2012 is equipped with a sliding sleeve structure, which can effectively limit the movement trajectory of the extrusion block 2013, ensure that it advances smoothly along the predetermined straight direction, avoid jamming, uneven wear or docking failure caused by uneven force or angular deviation, and improve the reliability and service life of the device.

[0024] Specifically, the front end of the positioning rod 2022 has a tapered structure, which facilitates automatic guidance into the mating hole of the staple cartridge assembly during the docking process, improving the accuracy and convenience of docking.

[0025] It should be noted that the front end of the positioning rod 2022 is designed with a tapered structure, which has good guiding performance. It can automatically guide the centering of the staple cartridge assembly and the stapler body in the initial docking stage, reducing the difficulty of manual alignment and improving docking accuracy and speed. It is especially suitable for clinical operation environments with limited space or poor field of vision.

[0026] Specifically, the inner wall of the fixing sleeve 2021 is provided with anti-slip texture or elastic gasket, which can enhance the friction with the outer wall of the nail cartridge assembly and prevent relative rotation or detachment after docking.

[0027] It should be noted that the anti-slip texture or elastic washer on the inner wall of the fixation sleeve 2021 can increase the frictional resistance of the contact surface after the staple cartridge assembly is inserted, preventing it from rotating or axially slipping during operation, further enhancing the stability and safety of the connection, and ensuring the smooth progress of the surgical operation.

[0028] In use, first place the quick docking and stabilizing device for the intracavitary cutting stapler cartridge assembly on the operating table and ensure its stability. The operator inserts the stapler cartridge assembly to be installed into the base 1011 of the fixing component 101. The elastic clamping structure inside the fixing block 1012 automatically clamps the stapler cartridge assembly, achieving initial positioning and anti-loosening fixation to prevent it from shaking or falling off during subsequent operations. Then, align the stapler body with the splicing component 202 of the docking mechanism 200 and move it closer. At this time, rotate the adjusting handle 2011, which drives the compression block 2013 along the guide rod 2012 through its internal thread transmission or lever mechanism. The guide rod 2012 moves forward along a fixed straight trajectory, and the sliding sleeve ensures that the compression block 2013 moves smoothly and without deviation, thereby applying a uniform clamping force to the staple cartridge assembly, making it firmly fit against the docking end of the stapler. During the docking process, the front end of the positioning rod 2022 in the splicing assembly 202 has a conical structure, which can automatically guide it into the mating hole on the staple cartridge assembly, achieving a fast and accurate alignment connection, significantly reducing the difficulty of manual alignment. At the same time, the inner wall of the fixing sleeve 2021 is provided with anti-slip texture or elastic washer, which further enhances the friction with the outer wall after the staple cartridge assembly is inserted, preventing relative rotation or axial loosening after docking.

[0029] In summary, by setting up a coordinated structure between the fixing component 101 and the docking mechanism 200, the fast positioning and stable connection of the staple cartridge assembly are achieved. The elastic clamping structure and the conical positioning rod 2022 improve the accuracy and convenience of docking. The compression component 201 is smoothly pressed under the guidance of the guide rod 2012 to ensure reliable connection. The anti-slip texture or elastic washer on the inner wall of the fixing sleeve 2021 further prevents loosening during use, thus improving the efficiency and safety of the installation of the staple cartridge assembly of the intracavitary cutting stapler.
