DETAILED DESCRIPTION
[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the following will combine the drawings in the embodiments of the present application to make a clear and complete description of the technical solutions in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, but not all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.
[0031] In the description of the present application, it should be noted that the terms "in", "out", and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship commonly used when the product of the present application is used, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", and the like are only used to distinguish the description and cannot be understood as indicating or implying relative importance.
[0032] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "set", "connected" should be broadly understood, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium, or it can be connected inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0033] Figure 1 A schematic diagram of an adapter provided by an embodiment of the present application, Figure 2 A second schematic diagram of an adapter provided by an embodiment of the present application, as Figures 1-2 As shown in the figure, the adapter 1 comprises an adapter main body 10, the adapter main body 10 comprises an inlet end 11 and an outlet end 12, and the inlet end 11 and the outlet end 12 are connected through a hollow channel 13 inside the adapter main body 10.
[0034] The inlet end 11 is provided with an adapter fixing protrusion 14, and the outlet end 12 is provided with an adapter clamping component 15, the adapter fixing protrusion 14 is used for cooperating and connecting with the clamping component of the first instrument; the adapter clamping component 15 is used for cooperating and connecting with the fixing protrusion of the second instrument. In an embodiment, the first instrument can be a glass cutting machine kit; the second instrument can be a microsyringe. Hereinafter, the first instrument is taken as a glass cutting machine kit, and the second instrument is taken as a microsyringe. Specifically, the adapter clamping component 15 is designed to be micro-deformable to adapt to and fix the fixing protrusion of the microsyringe, and the adapter fixing protrusion 14 is designed to be clamped by the matching clamping component of the glass cutting machine kit to realize fixation.
[0035] The adapter 1 device can adapt to a variety of instruments without the need for additional adapters or tools. By rotating clamping of the clamping component and the fixing protrusion with other medical instruments, the adapter 1 can quickly connect and disconnect with medical instruments, greatly reducing the time for surgical preparation and switching instruments.
[0036] A pressure vent 16 is provided in the middle of the adapter snap-fit component 15. The pressure vent 16 communicates with the hollow channel 13 inside the adapter body 10. An adapter sealing ring 17 is provided on the outer surface of the pressure vent 16 to ensure an airtight connection between the adapter 1 and the second instrument. For example, the adapter sealing ring 17 can be a rubber ring or other elastic material, and there can be one or more of them. The adapter sealing ring 17, through precise dimensional matching with the micro-syringe, enables easy insertion and removal of the instrument while maintaining airtightness. This design not only ensures sealing during the surgical process but also ensures leak-free transmission of gas or liquid between the adapter 1 and the micro-syringe.
[0037] Figure 3 A cross-sectional structural schematic diagram of an adapter provided in an embodiment of this application is shown below. Figure 3 As shown, in one embodiment, the hollow channel 13 includes a first channel 131 near the inlet end 11 and a second channel 132 near the outlet end 12, wherein the aperture of the first channel 131 is larger than the aperture of the second channel 132. This design allows the fluid to gradually accelerate as it flows from the inlet end 11 to the outlet end 12, thereby achieving a smooth pressure transition and reducing the impact of the fluid on the micro-injector at the outlet end 12.
[0038] In one embodiment, the second channel 132 adopts a progressively contracting structure, where the aperture of the second channel 132 near the inlet end 11 is larger than the aperture of the side away from the inlet end 11. This helps to gradually increase the flow velocity as the fluid passes through, while reducing turbulence and pressure loss, thereby improving the efficiency of fluid transport. The second channel 132 can also be other shapes, such as a stepped contracting structure, a spiral structure, a buffer chamber structure, an adjustable structure, etc., as long as the new structure can ensure that it meets the requirements for stable gas path pressure.
[0039] In one embodiment, the second channel 132 can be conical or a more rounded conical shape, so that the pressure changes more steadily when the gas enters the syringe and adapter 1. In practical applications, this conical structure helps to reduce the formation of air bubbles and ensures that the drug or liquid can flow smoothly and continuously from the first instrument to the second instrument.
[0040] In one embodiment, the adapter fixing protrusion 14 includes a first protrusion 141 and a second protrusion 142 perpendicular to the outer surface of the adapter body 10. The two protrusions can disperse the stress generated by connection and disconnection operations, reduce the direct pressure on the adapter body 10, thereby improving durability and service life.
[0041] The first protrusion 141 and the second protrusion 142 are symmetrically arranged relative to the hollow channel 13. This symmetrical arrangement of the protrusions improves the stability and reliability of the connection with the first instrument locking component. The first protrusion 141 and the second protrusion 142 can also serve as visual markers to help the operator quickly identify the connection direction and position of the adapter 1 and the medical device, ensuring correct installation.
[0042] In one embodiment, the first protrusion 141 and the second protrusion 142 are integrally formed with the adapter body 10. The integrally formed structure simplifies the manufacturing process and improves the strength and durability of the adapter.
[0043] like Figures 1-3 As shown, in one embodiment, the adapter fixing protrusion 14 includes a first end face 143 and a second end face 144 that contact the first instrument. The first end face 143 and the second end face 144 are provided with a textured structure to increase friction. For example, the textured structure is a mesh pattern. The mesh pattern increases the friction with the end face that contacts the first instrument, improving the stability of the connection and preventing accidental detachment.
[0044] In one embodiment, the adapter snap-fit component 15 includes a third end face 154 that contacts the second instrument. The third end face 154 is provided with a textured structure to increase friction; exemplarily, the textured structure is a mesh pattern. These textures increase the friction with the instrument contact surface, improving the stability of the connection. In actual operation, even when the instrument or hand is wet, the mesh pattern provides sufficient grip to ensure that the connection does not accidentally loosen.
[0045] The mesh pattern increases the friction with the contact surface of the second instrument, improving the stability of the connection and preventing accidental detachment.
[0046] The contact surface of the adapter 1 that connects to the medical device may include a structure that has been specially treated to increase friction. Such special treatment includes, but is not limited to, adding texture, surface roughening, coating or plating, to improve stability and durability when connected to the medical device.
[0047] In one embodiment, the adapter snap-fit component 15 includes: a base plate 151 perpendicular to the outer surface of the adapter body 10, with a first groove 152 and a second groove 153 at both ends of the base plate 151; a pressure vent 16 located in the middle of the base plate 151 and penetrating the base plate 151; the first groove 152 and the second groove 153 are symmetrical with respect to the pressure vent 16. The symmetrical groove design and the position of the pressure vent 16 help to evenly distribute pressure and improve the stability and airtightness of the adapter.
[0048] Furthermore, the first groove 152 and the second groove 153 are provided with protrusions at their ends to improve the strength and stability of the connection with the medical device, and to provide better feel and ease of operation. This allows doctors or operators to more easily perceive whether the device has been correctly installed during the operation, which helps to improve surgical efficiency and reduce operational errors.
[0049] Figure 4 This is a three-dimensional schematic diagram of the micro-injection device provided in the embodiments of this application, as shown below. Figure 4 As shown, the micro-injection device includes: the adapter 1, the glass cutter kit 2, and the micro-injector 3 described in the above embodiments.
[0050] Figure 5 This is a schematic diagram of the structure of a glass cutting machine kit 2 provided in one embodiment of this application. Figure 6 This is a cross-sectional schematic diagram of a micro-injection device provided in an embodiment of this application. For example... Figure 5 and Figure 6 As shown, the outlet of the glass cutter kit 2 is provided with a glass cutter snap-fit component 21, which is rotatably snapped into place with the adapter fixing protrusion 14. Specifically, the glass cutter snap-fit component 21 also includes a glass cutter sealing ring 22, which fits tightly against the inner wall of the first channel 131 of the adapter 1 to ensure an airtight connection between the glass cutter kit 2 and the adapter 1. For example, the glass cutter sealing ring 22 can be a rubber ring or other elastic material.
[0051] After inserting the sealing ring 22 of the glass cutter into the first channel 131 of the adapter body 10, rotate it 90° so that the glass cutter locking part 21 is aligned with the adapter fixing protrusion 14, that is, rotated into place, and the glass cutter kit 2 locks the adapter 1. For example, when a click is heard when rotating into place, it is rotated into place.
[0052] Furthermore, a rubber pad can be provided on the contact surface between the glass cutter clamping component 21 and the adapter fixing protrusion 14 to press the adapter fixing protrusion 14 with an interference fit. The interference fit rubber pad can increase the stability of the connection between the adapter 1 and the glass cutter kit 2. The elasticity of the rubber pad allows it to deform under pressure, thereby tightly filling the gap between the adapter fixing protrusion 14 and the glass cutter clamping component 21 and improving the firmness of the connection.
[0053] Figure 7 This is a schematic diagram of the structure of a micro-injector 3 provided in an embodiment of this application. For example... Figure 6 and Figure 7As shown, the inlet of the micro-injector 3 is provided with a syringe fixing protrusion 31, which is rotatably locked with the adapter locking component 15; the pressure vent 16 is embedded in the empty cylinder of the micro-injector 3, and the adapter sealing ring 17 forms an airtight connection with the empty cylinder of the micro-injector 3. For example, the edge of the syringe fixing protrusion 31 is provided with a protrusion, which can make the adapter locking component 15 lock the micro-injector 3 and prevent it from falling off.
[0054] Insert the pressure vent 16 of the adapter body 10 into the empty cylinder of the micro-syringe 3 to form an airtight connection. Then rotate it 90° to cause a slight deformation of the adapter locking component 15, which locks the syringe fixing protrusion 31. When the adapter locking component 15 is aligned with the syringe fixing protrusion 31, that is, when the rotation is in place, the adapter body 10 locks the micro-syringe 3. For example, when a click is heard after rotation, the connection is complete.
[0055] The above embodiment provides a complete micro-injection device that enables a quick, stable, and airtight connection between the micro-injector 3 and the glass cutter kit 2 through an adapter 1, thereby improving the safety and efficiency of the entire system and reducing the possibility of incorrect connection.
[0056] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.
[0057] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
