[0023] Example
[0024] Reference Figures 1-4 This embodiment of the present invention provides a convenient connection device for a power-operated intracavitary cutting anastomosis device with quickly replaceable components, comprising:
[0025] The connecting mechanism 100 includes a connecting block 101, a connecting sleeve 102, a connecting tube 103, an elastic locking block 104, a fixing sleeve 105, a slot 106, and a limiting block 107. The connecting block 101 is disposed on the main body of the electric intracavitary cutting stapler and is used to provide a connection fulcrum. The connecting sleeve 102 is sleeved on the outside of the connecting block 101 and is used to realize axial limiting and rotational engagement between components. The connecting tube 103 is disposed at one end of the connecting sleeve 102 and is used to connect with external functional components. The elastic locking block 104 is disposed on the inner wall of the connecting sleeve 102 and is used to cooperate with the slot 106 to achieve quick locking. The fixing sleeve 105 is disposed on the outside of the connecting tube 103 and is used to protect and limit the connecting structure. The slot 106 is disposed on the outer surface of the connecting block 101 and is used to cooperate with the elastic locking block 104 to achieve quick locking. The limiting block 107 is disposed on the connecting sleeve 102 and is used to prevent the connecting sleeve 102 from excessively rotating or disengaging, ensuring the stability of the connecting structure.
[0026] Specifically, the elastic block 104 is equipped with a reset spring, which can automatically reset and lock into the slot 106 after the external force is released, realizing the automatic locking function of the connecting component and improving the convenience of operation and the reliability of connection.
[0027] It should be noted that the elastic locking block 104 is equipped with a reset spring, which can automatically reset and lock into the slot 106 after the operator releases the external force, realizing the quick and automatic locking of the connecting components, effectively improving the convenience and reliability of the connection operation, avoiding connection failure due to human error, and is suitable for the scenario of quickly changing functional components during surgery.
[0028] Specifically, the connecting sleeve 102 and the connecting block 101 have a rotatable fit structure, which allows the connecting components to be rotated and adjusted to a limited angle even when locked, to meet the needs of different surgical operation angles.
[0029] It should be noted that the connecting sleeve 102 and the connecting block 101 are rotatable fit structures. After the quick snap-fit locking is completed, a limited angle of rotation adjustment can still be performed, so that the external functional components can flexibly adjust the angle according to the surgical approach direction, adapt to the needs of different surgical operation angles, and improve the clinical applicability and operation convenience of the equipment.
[0030] Specifically, the limiting block 107 is provided with an angle limiting structure to limit the rotation angle range of the connecting sleeve 102 and prevent connection failure or damage to functional components due to excessive rotation.
[0031] It should be noted that the limiting block 107 is equipped with an angle limiting structure to limit the rotation angle range of the connecting sleeve 102, preventing the connection structure from failing or external functional components from being mechanically damaged due to excessive rotation, thereby ensuring connection stability and equipment lifespan, and improving safety and controllability during operation.
[0032] Specifically, the connecting pipe 103 is provided with an internal thread structure for matching and connecting with the external thread of the external functional component, providing a secondary locking function on the basis of snap-fit locking, thereby enhancing the firmness and safety of the connection.
[0033] It should be noted that the connecting pipe 103 is provided with an internal thread structure for matching and connecting with the external thread of the external functional component. On the basis of the initial locking of the elastic block 104 and the slot 106, it further provides a secondary locking function of thread locking, which significantly enhances the robustness and safety of the connection structure and is suitable for high-intensity cutting or high-torque operation scenarios.
[0034] Specifically, the fixing sleeve 105 is equipped with anti-slip texture, which makes it easy for the operator to manually rotate or disassemble the connecting components, thereby improving the human-computer interaction experience and clinical operation efficiency.
[0035] It should be noted that the fixing sleeve 105 has anti-slip texture, which makes it easy for the operator to obtain good grip friction when manually rotating or disassembling the connecting components, improving the human-computer interaction experience and clinical operation efficiency. It is especially suitable for scenarios where gloves are worn during surgery, ensuring the safety, stability and efficiency of the operation process.
[0036] In use, the connecting mechanism 100 is first installed and operated as the core component of the entire system. The connecting block 101 is located on the main body of the electric intracavitary cutting stapler, providing a stable connection fulcrum to ensure that each functional component can be reliably connected to the main body. The connecting sleeve 102 is fitted outside the connecting block 101, and through the axial limiting and rotational fitting structure, it achieves precise alignment and stable connection between components, allowing the connecting components to be rotated and adjusted to a limited angle even in the locked state to meet the needs of different surgical operation angles. The connecting tube 103 is located at one end of the connecting sleeve 102 and is used to dock with external functional components. It has an internal thread structure, and after the elastic locking block 104 and the slot 106 complete the initial locking, it further provides a secondary locking function to enhance the firmness and safety of the connection. The elastic locking block 104 is located on the inner wall of the connecting sleeve 102 and is equipped with a return spring. After the external force is released, it automatically resets and locks into the slot 106 to realize the connection. The rapid automatic locking of the components significantly improves the convenience and reliability of operation, avoiding connection failure due to human error. The fixing sleeve 105 is located on the outside of the connecting tube 103, which not only provides additional protection and limitation for the connection structure, but also has anti-slip texture, making it easy for the operator to manually rotate or disassemble the connecting components. It is especially suitable for scenarios where gloves are worn during surgery, ensuring the safety, stability and efficiency of the operation process. The slot 106 is located on the outer surface of the connecting block 101 and fits tightly with the elastic locking block 104 to achieve rapid locking, ensuring the stability and reliability of the connection structure. The limiting block 107 is located on the connecting sleeve 102 and has an angle limiting structure to limit the rotation angle range of the connecting sleeve 102, preventing connection failure or damage to functional components due to excessive rotation, thereby ensuring the service life of the equipment and operational safety. This design allows the operator to flexibly adjust the angle of the functional components during surgery, while ensuring that the connection structure will not fail due to improper operation.
[0037] In summary, by setting up a quick connection structure consisting of a connecting block 101, a connecting sleeve 102, an elastic locking block 104, and a locking groove 106, and combining the internal thread locking of the connecting tube 103 with the angle control function of the limiting block 107, the shortcomings of existing connection devices in terms of component replacement efficiency, structural stability, and operational adaptability are effectively solved, and the convenience, safety, and applicability of the electric endocavitary cutting stapler in clinical use are improved.
