Description

Technical Field

[0001] The utility model relates to the field of medical devices, and particularly to a quick-release structure adapted to a sterile cover. Background Art

[0002] In recent years, with the continuous development and upgrading of medical devices and equipment, the demand for a sterile operation environment has been increasing. During surgeries, diagnoses, and treatments, medical devices need to be frequently replaced and disassembled, and maintaining a sterile environment is the key to ensuring medical safety and quality. Therefore, designing a quick-release mechanism that can be adapted to a sterile cover and is easy to quickly disassemble and assemble has become an important topic in the industry.

[0003] In the prior art, there have been some patents and solutions attempting to solve this problem. For example, patent CN218979431U proposed a quick-release mechanism adapted to a sterile cover and convenient for disassembly and assembly. However, this solution still has problems of complex structure and high manufacturing cost in practical applications. In addition, patents such as CN106102639A also provided similar technical solutions, but these solutions generally face challenges of complex application scenarios and complex structures and are difficult to meet actual needs.

[0004] Existing quick-release mechanisms often adopt elastic structures in their designs to achieve the function of quick disassembly and assembly. However, the application of elastic structures on plastic parts has a risk of being easily damaged. Especially in the case of frequent operations, the durability and reliability of plastic parts are difficult to guarantee. This not only increases the cost of maintenance and replacement but also may affect the safety and efficiency of medical operations.

[0005] Taking the RCM fixed-point indicator as an example, this device requires precise positioning and stability during surgeries and needs to be quickly disassembled and replaced after surgeries. The application of traditional quick-release mechanisms on the RCM fixed-point indicator often causes operation difficulties and equipment damage due to complex structures, inconvenient disassembly and assembly, and easy damage of elastic structures. This not only increases the preparation time for surgeries but also may have an adverse impact on the accuracy of surgeries. Summary of the Invention

[0006] To solve the above technical problems, the utility model provides a quick-release structure adapted to a sterile cover.

[0007] The utility model is realized through the following technical solutions:

[0008] A quick-release structure adapted to a sterile cover of the utility model includes a functional component that needs to achieve the quick-release function. Two plugs are arranged on the functional component; the two plugs are detachably assembled and connected with a quick-release buckle mechanism; the quick-release buckle mechanism is an elastic link mechanism and is connected to a bracket; the quick-release buckle mechanism is assembled and connected with a quick-release push rod; one end of the quick-release push rod away from the quick-release buckle mechanism is fixedly connected with a quick-release button; the quick-release push rod is assembled and connected with a reset mechanism arranged on the bracket, and the reset mechanism is a mechanical energy storage mechanism, and the reset mechanism makes the quick-release push rod always have a tendency to maintain the initial position; when the quick-release push rod is in the initial position, the quick-release buckle mechanism is in a state where it can just lock the two plugs.

[0009] The above design can ensure that the functional component can achieve quick disassembly and installation during use, and is applicable to medical devices and instruments that need to be frequently replaced. The detachable connection between the two plugs and the quick-release buckle mechanism makes the assembly and disassembly of the device more convenient. As an elastic link mechanism, the quick-release buckle mechanism ensures the stability and reliability of the buckle through its connection with the bracket. The design of the quick-release push rod makes the operation simpler. Just press the quick-release button to achieve quick disassembly, which greatly improves the operation efficiency. The setting of the reset mechanism ensures that the quick-release push rod can automatically return to its position, ensuring that the device is still in the initial position when used again, which is convenient for operation.

[0010] Further, the functional component is a component or mechanism that realizes medical functions. The types of the functional component include the RCM fixed-point indicating rod. The functional component can be a component required in a variety of medical application scenarios. In addition to the RCM fixed-point indicating rod, it can also include other medical components that need to be quickly disassembled and assembled, such as the connecting components of surgical instruments, the interfaces of infusion devices, etc. This versatility enables the quick-release structure to adapt to a variety of medical devices, improving its application universality and practicability. At the same time, the standardized design of the functional component also facilitates the interchangeable use between different types of medical devices, enhancing the versatility of medical devices.

[0011] Further, the quick-release buckle mechanism includes buckle rods, a push rod pin shaft, and a rotating pin shaft; there are two buckle rods, and each buckle rod includes a rod portion and a bent portion; the two rod portions are arranged in a "V" shape and are simultaneously hinged to the quick-release push rod through the same push rod pin shaft, and the other ends are respectively hinged to the bracket through a rotating pin shaft; the end of the rod portion of the buckle rod away from the quick-release push rod extends outward to form a bent portion, and the bending direction points to the quick-release push rod. The end of the bent portion is set in a hook shape and is assembled and connected with the plug.

[0012] The structural design of the quick-release buckle mechanism fully considers the mechanical principles. Through the buckle rods arranged in a "V" shape, a stable buckling force can be generated under the push of the push rod. The design of the bending part increases the mating area with the plug, making the buckle more firm. The hook-shaped end design facilitates the fixing and disassembly operations of the plug, enhancing the convenience and safety of the operation. In addition, the combined use of the push rod pin and the rotating pin enables the entire buckle mechanism to maintain balance when applying force, avoiding structural deformation or failure caused by unilateral force.

[0013] Furthermore, the plug is in a boss shape, and through holes that cooperate with the quick-release buckle mechanism are provided on it; transition rounded corners or chamfers are provided at the outer edge of the plug. The boss design of the plug not only enhances its structural strength but also provides a larger operating space, facilitating the cooperation with the quick-release buckle mechanism. The setting of the through holes enables the plug to achieve precise positioning and stable connection with the buckle mechanism. The design of the transition rounded corners or chamfers at the outer edge reduces friction and wear during the operation, increasing the service life of the plug. At the same time, the rounded corner or chamfer design also reduces the risk of injury to the surgical staff, improving the safety of the operation.

[0014] Furthermore, the reset mechanism is a compression spring sleeved on the quick-release push rod; a plug is provided at the lower end of the quick-release push rod, and the reset mechanism is located between the bracket and the plug and is always in a compressed state. Through the use of the compression spring, the reset mechanism realizes the automatic reset function of the quick-release push rod. The compression spring is always in a compressed state, ensuring the automatic return of the push rod after each operation. The design of the plug prevents the compression spring from falling off, ensuring the stability of the reset mechanism. With such a design, the user does not have to worry about the problem of the push rod not being able to return during the operation, improving the reliability of the device and the fluency of the operation.

[0015] Furthermore, a sterile film is provided between the functional component and the bracket; through holes for the plug to pass through are opened on the sterile film; the sterile film is fixedly connected to the functional component; the area of the sterile film is larger than the contact surface between the functional component and the bracket. The setting of the sterile film further improves the hygienic performance of the device, preventing the entry of bacteria and other contaminants. The design of the through holes enables the plug to pass through smoothly and connect with the quick-release buckle mechanism while maintaining a sterile environment. The sterile film is fixedly connected to the functional component, ensuring its stability during the operation. The design of the film area being larger than the contact surface provides a larger protection range, further preventing the risk of contamination and ensuring the safety of the medical operation and the sterile environment.

[0016] Furthermore, a boss is provided at the connection between the functional component and the plug, and the plug is arranged on the boss; the sterile film is arranged at the position between the bottom surface of the boss and the functional component. By providing a boss at the connection between the functional component and the plug, the fixing stability of the plug is increased. The plug is placed on the boss, which can better cooperate with the quick-release buckle mechanism, enhancing the firmness and reliability of the connection. The sterile film is arranged between the bottom surface of the boss and the functional component, effectively isolating the contact between the functional component and the outside world, and further improving the sterile protection effect. Such a design not only ensures the sterile operation of the device but also improves the connection strength between the plug and the functional component.

[0017] Furthermore, a number of positioning holes are provided on the boss; positioning pins corresponding to the number of positioning holes are provided on the bracket; the positioning holes and the positioning pins are inserted and matched with each other. The positioning holes on the boss and the positioning pins on the bracket are used in cooperation with each other, which can achieve the precise positioning and stable connection of the functional component and the bracket. The design of multiple positioning holes enables the functional component to be adjusted and fixed at different positions, increasing the flexibility and applicability of the device. The insertion and matching of the positioning holes and the positioning pins ensure the firmness of the connection, avoiding problems such as loosening or displacement caused by vibration or operation. This design greatly improves the use stability and operation accuracy of the device.

[0018] The beneficial effects of the present utility model are as follows:

[0019] Simplified structure and reduced cost: Through optimized design, the structure of the quick-release mechanism is significantly simplified in this technical solution, reducing the number of components and complexity. This not only reduces the manufacturing cost but also reduces the difficulty of assembly and maintenance, improving the overall economy.

The user only needs to press the quick-release button to easily achieve the quick disassembly and installation of the functional component. Such a design greatly improves the convenience and efficiency of medical devices in actual operation, meeting the requirements of frequent replacement and adjustment.

[0021] Improved durability and reliability: By using more durable materials and a reasonable elastic structure design, this technical solution avoids the problem that the elastic structure in the traditional quick-release mechanism is easily damaged on plastic parts. This not only extends the service life of the device but also improves the reliability of the system, reducing equipment failures and downtime caused by part damage.

[0022] Guarantee of sterile operation environment: The design of the sterile film arranged between the functional component and the bracket can effectively isolate the external environment, prevent the entry of pollutants, and guarantee a sterile operation environment. The fixing method and high-precision matching design of the sterile film further improve the sterile protection effect, ensuring the safety of medical operations.

[0023] Strong adaptability: The design of this quick-release mechanism is highly flexible and can be applied to various medical devices that require quick-release functions, such as the RCM fixed-point indicator. By replacing different functional components, this quick-release mechanism can meet the needs of a variety of medical application scenarios and has wide applicability.

[0024] Enhanced operation stability: The design of the quick-release buckle mechanism enables the functional component to be firmly locked after being installed in place and is not prone to loosening. Coupled with the precise positioning design, it ensures the stability and accuracy of the functional component during use, improving the operation performance and safety of the device.

[0025] Reliable reset function: The reset mechanism uses a compression spring or other energy storage components to ensure the automatic return function of the quick-release push rod after each operation. Such a design not only improves the fluency of operation but also ensures the recovery state of the system after each use, facilitating the next operation.

[0026] In summary, this utility model solves many problems in the prior art by simplifying the structure, improving durability, ensuring a sterile operation environment, and enhancing operation stability, providing an efficient and reliable solution for the quick disassembly and assembly and sterile operation of medical devices.
