Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a button that can be elastically sealed. Background Technology

[0002] With the advancement of medical technology, electrically powered surgical instruments are widely used in surgery and are favored by medical staff due to their labor-saving and convenient operation. For environmental protection and cost reduction considerations, instruments that can be reused after high-temperature sterilization are more popular with patients and society. For such instruments, ensuring thorough cleaning and sterilization while preventing damage during disinfection and use places higher demands on their structural sealing and durability.

[0003] Existing electrically powered sterilizable reusable instruments often suffer from poor sealing due to the need for clearance between moving parts. This allows cleaning fluids or high-temperature steam to seep in, damaging internal components and shortening their lifespan. While forcibly adding sealing rings to these clearances can prevent water ingress, it increases resistance and makes operation stiff. Therefore, there is an urgent need for an improved structure that balances smooth operation with long-term reliable sealing. Utility Model Content

[0004] The purpose of this invention is to provide a button that can be elastically sealed, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a button that can be elastically sealed, including a mounting hole and a housing with the mounting hole, wherein the mounting hole is provided with a button structure that can maintain a relative seal between the inner and outer parts of the mounting hole portion of the housing during pressing.

[0006] Preferably, the button structure includes: a fixing member disposed in the mounting hole, the fixing member having a guide portion; a push button slidably disposed on the fixing member along the guide portion; and a soft sleeve disposed on the outside of the fixing member and the button, covering both of them as a whole, so as to form a continuous seal and isolation during the pressing of the button.

[0007] Preferably, the fixing member has a plurality of barbs at the corresponding positions of the inner wall of the mounting hole.

[0008] Preferably, the outer edge of the fastener forms a gap with the wall of the mounting hole, and the outer edge of the soft sleeve is fixed in the gap.

[0009] Preferably, the outer edge of the mounting hole is provided with a first bend, and the fastener is provided with a second bend that cooperates with it. The first bend and the second bend are arranged at intervals relative to each other, so that the gap between them forms a bend-shaped path.

[0010] Compared with the prior art, the beneficial effects of this utility model are: By using a combination of a fixed component and a push button guide, along with an outer elastic soft sleeve to form a multi-stage sealing channel, continuous isolation of the button is achieved during operation. This not only effectively prevents high-temperature steam from penetrating and damaging internal components during sterilization, but also maintains a light and smooth operating feel, improving the reliability and service life of electric medical devices.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0015] In the description of this patent, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integrated connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this patent according to the specific circumstances.

[0016] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" means two or more, unless otherwise explicitly specified.

[0017] Example Please see Figure 1-5 As shown, the present invention provides a button technology solution that can be elastically sealed: a button that can be elastically sealed includes a mounting hole 1 and a housing 2 with a mounting hole 1. The mounting hole 1 is provided with a button structure 3 that can keep the inner and outer parts of the mounting hole part of the housing 2 relatively sealed during the pressing process.

[0018] The button structure 3 includes: a fixing member 301, a pressing button 303, and a soft sleeve 304. The fixing member 301 is disposed in the mounting hole 1, and a guide part 302 is provided on the fixing member 301. The pressing button 303 is slidably disposed on the fixing member 301 along the guide part 302. The soft sleeve 304 is disposed on the outside of the fixing member 301 and the pressing button 303, covering the two as a whole, so as to form a continuous seal during the button pressing process.

[0019] In this embodiment, the guide portion 302 is formed on the inner wall of the fixing member 301 to define the axial sliding path of the button 303, so that it can accurately drive the switch assembly located inside the housing 2 at the end of the pressing stroke to complete the conduction or disconnection operation.

[0020] The fastener 301 is provided with several barbs 4 at corresponding positions on the inner wall of the mounting hole 1. When assembled, the barbs 4 are elastically engaged in the mounting hole 1. After the hook surface is against the hole wall, the fastener 301 can be quickly positioned axially. At the same time, this locking method leaves a gap 5 between the outer edge of the fastener 301 and the outer wall of the mounting hole 1, providing reliable space for the insertion and clamping of the edge of the soft sleeve 304.

[0021] The outer edge of the fastener 301 forms a gap 5 with the wall of the mounting hole 1, and the outer edge of the soft sleeve 304 is fixed in the gap 5. This annular structure not only makes the appearance smooth, but also works with the barb 4 to generate radial clamping force, thereby firmly fixing the soft sleeve 304 and maintaining a long-lasting seal.

[0022] The outer edge of the mounting hole 1 is provided with a first bent portion 6, and the fastener 301 is provided with a second bent portion 7 that cooperates with it. The first bent portion 6 and the second bent portion 7 are arranged at intervals relative to each other, so that the gap 5 between them is a bent path. After the edge of the soft sleeve 304 is embedded in this folded gap 5, it can contact and bear force with multiple folded surfaces at the same time, thereby greatly improving the clamping strength and extending the sealing passage.

[0023] The working principle of this utility model is as follows: During assembly, the pressure button 303 is first embedded into the fixing member 301, and then the elastic sleeve 304 is covered on the outside of the fixing member 301 and the pressure button 303, with its edge pre-positioned at the second bend 7 of the fixing member 301. The entire assembly is then pressed into the mounting hole 1 along the assembly direction. The barbs 4 on the outer periphery of the fixing member 301 elastically hook back after passing over the hole wall, firmly locking into the inner wall of the mounting hole 1; simultaneously, the edge of the sleeve 304 is clamped within the zigzag gap 5 by the first bend 6 and the second bend 7, achieving reliable positioning and sealing.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
