Description

Technical Field

[0001] This utility model relates to the technical field of electronic mirrors, and in particular to the technical field of electronic mirror suction valve structures. Background Technology

[0002] Endoscopy is widely used in clinical practice for examination, diagnosis, and minimally invasive treatment of various diseases across different departments. Compared to traditional open surgery, minimally invasive surgery offers numerous advantages, including lower pain, smaller incisions, less bleeding, lower risk of infection, faster recovery, quicker procedures, shorter hospital stays, and fewer postoperative complications, making it highly favored by patients, doctors, hospitals, and medical insurance. While new endoscopic products continue to emerge with the development of minimally invasive surgery, the suction valve function remains essential, playing a crucial role in the exploration of the urinary system and the removal of residual stones.

[0003] Existing electronic endoscope suction valve structures, as shown in patent document CN119548074A, mostly adopt a reusable structural design. To achieve the valve core's reset and sealing functions, a spring assembly needs to be built into the internal cavity. However, the reusable nature of these valves presents them with stringent maintenance requirements: after each use, they must undergo multiple processes such as disassembly, high-temperature sterilization, precision cleaning, and functional calibration. This not only consumes a significant amount of medical resources and time but also poses risks of component wear due to improper disassembly and cross-infection caused by incomplete sterilization. Furthermore, the built-in springs are exposed to humid and corrosive environments for extended periods, which can lead to elasticity decay and metal fatigue, further affecting the valve's sealing performance and service life, and posing potential risks to the safety and stability of clinical operations. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art by proposing a maintenance-free electronic mirror suction valve structure that can solve the above problems.

[0005] To achieve the above objectives, this utility model proposes a maintenance-free electronic mirror suction valve structure, including a suction button component and a suction valve seat component. The suction button component includes an elastic seat body, with a button seat body installed at the bottom of the elastic seat body. The button seat body is provided with a suction interface and an air inlet. A push button is installed on the inner side of the elastic seat body, and a button sealing ring is installed at the bottom of the button seat body. The suction valve seat component includes a valve seat body, with a valve seat body installed at the bottom of the button seat body. A valve bottom bend is provided at the bottom of the valve seat body. The outer side of the button sealing ring is sealed to the valve seat body. A sealing head is provided at the bottom of the push button, and the inner side of the button sealing ring is sealed to the sealing head. The push button includes a mounting base and a core rod. The core rod is connected to the bottom of the mounting base, and a sealing gasket is provided on the bottom surface of the mounting base. A movable groove is opened on the button seat body, and the mounting base is movably disposed in the movable groove. A limiting step matching the mounting base is protruding in the movable groove. When the push button is pressed, the sealing gasket abuts against the limiting step, sealing the movable groove.

[0006] Preferably, the air inlet is located above the suction port, and the limiting step is located above the suction port.

[0007] Preferably, the outer side of the button seat is provided with a limiting protrusion ring, the upper part of the limiting protrusion ring is provided with an annular groove, the limiting protrusion ring is provided with a notch, the annular groove is located below the suction port, and the inner side of the valve seat is provided with a boss lug that matches the notch.

[0008] Preferably, the button sealing ring includes a mounting part, a connecting ring groove is provided below the mounting part, a connecting protrusion is provided at the bottom of the button seat to match the connecting ring groove, a sealing part is provided below the connecting ring groove, an annular protrusion is provided on the outer side of the sealing part, and a sloping conical surface is provided on the inner side of the valve seat, with the annular protrusion abutting against the sloping conical surface.

[0009] Preferably, the relative directions of the suction port and the air inlet are either straight-line or perpendicular at ninety degrees.

[0010] The beneficial effects of this utility model are as follows: The suction button component of this utility model is maintenance-free and disposable after single use. Because it is made of injection molded parts and silicone, the cost is low and replacement is convenient. The core rod is reset by an external elastic seat, which simplifies the internal structure, improves the internal sealing performance, and reduces production costs. This utility model has a bidirectional sealing structure, with a sealing gasket 3 for downward pressing and a button sealing ring 6 for upward reset, ensuring no leakage under negative pressure and high suction efficiency. The installation and locking of this utility model are convenient and reliable. After aligning the notch on the suction button component with the boss lug on the suction valve seat component, it can be rotated into place. Because the button sealing ring has a certain compression and rebound after mating, the suction button component falls into the annular groove of the valve seat body after being rotated into place, thus forming a self-locking mechanism.

[0011] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description

[0014] See Figures 1 to 9The maintenance-free electronic microscope suction valve structure includes a suction button component and a suction valve seat component. The suction button component includes an elastic seat 1, with a button seat 5 mounted on the bottom of the elastic seat 1. The button seat 5 has a suction interface 4 and an air inlet 51. A push button 2 is mounted on the inner side of the elastic seat 1, and a button sealing ring 6 is mounted on the bottom of the button seat 5. The suction valve seat component includes a valve seat 8, with a valve seat 8 mounted on the bottom of the button seat 5. The bottom of the valve seat 8 has a valve bottom bend 7, and the outer side of the button sealing ring 6 is sealed to the valve seat 8. The button core 2 has a sealing head 9 at its bottom, and the inner side of the button sealing ring 6 is sealed to the sealing head 9. The button core 2 includes a mounting base 21 and a core rod 22. The core rod 22 is connected to the bottom of the mounting base 21, and a sealing gasket 3 is provided on the bottom surface of the mounting base 21. A movable groove 52 is provided on the button seat 5, and the mounting base 21 is movably disposed in the movable groove 52. A limiting step 53 matching the mounting base 21 is protruding in the movable groove 52. When the button core 2 is pressed, the sealing gasket 3 abuts against the limiting step 53 to seal the movable groove 52.

[0015] The air inlet 51 is located above the suction port 4, and the limiting step 53 is located above the suction port 4.

[0016] The relative directions of the suction port 4 and the air inlet 51 are either straight-line or perpendicular at ninety degrees.

[0017] The air inlet is slightly higher than the suction port of the negative pressure pump, with a certain height difference in the straight or 90-degree direction, which conforms to the principle of air intake structure.

[0018] The button seat 5 has a limiting protrusion ring 54 on its outer side, an annular groove 55 above the limiting protrusion ring 54, a notch 56 on the limiting protrusion ring 54, the annular groove 55 being located below the suction port 4, and a boss lug 81 matching the notch 56 on the inner side of the valve seat 8.

[0019] There are two symmetrical notches 56 and boss lugs 81.

[0020] The suction button component I can rotate in both directions after being pressed in, making it easy for the operator to operate with either hand. It is simple to assemble and highly efficient to operate.

[0021] The button sealing ring 6 includes a mounting part 61, a connecting ring groove 62 is provided below the mounting part 61, a connecting protrusion 57 is provided at the bottom of the button seat 5 to match and install the connecting ring groove 62, a sealing part 63 is provided below the connecting ring groove 62, an annular protrusion 64 is provided on the outer side of the sealing part 63, and an inclined conical surface 82 is provided on the inner side of the valve seat 8, with the annular protrusion 64 abutting against the inclined conical surface 82.

[0022] Work process: Connect the suction interface of the electronic endoscope suction button component to the negative pressure pipeline of the external device—the negative pressure suction system. After starting the negative pressure pump, the suction interface 4 is connected to the air inlet on the left side of the suction button component, forming a short circuit with the atmosphere, and the negative pressure pump only draws in air. When the button core 2 is pressed, the deformation and compression of the elastic seat 1 causes the sealing gasket 3 to fit tightly with the button seat 5, blocking the air inlet on the left side of the suction button component and forming a seal on the upper cavity of the suction button component. At this time, the button core 2 moves downward, causing the lower end of the button core 2 to separate from the button sealing ring 6, forming a passage. At this time, the instrument channel at the (far) end of the electronic lens is connected to the valve bottom bend 7 of the suction valve seat component, and after passing through the valve seat 8, it is connected to the suction interface 4 on the suction button component to form a negative pressure circuit, realizing the negative pressure suction function of the electronic endoscope from the human body cavity, achieving the purpose of removing and recovering foreign objects after surgery.

[0023] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
