Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a quick-release device for an endoscope host and an endoscope host. Background Technology

[0002] Endoscope main units are precision electronic devices in the medical device field, integrating complex imaging and processing circuits. The main unit's casing not only protects these core components but also needs to meet the requirements of electromagnetic shielding, heat dissipation, and resistance to frequent disinfection and cleaning in medical environments. Therefore, the reliability, sealing, and ease of use of the casing's connections are crucial.

[0003] Currently, the connection and fixation between the upper shell and front shell of the endoscope main unit mainly adopts two methods: threaded connection or fixing buckle. However, the installation and disassembly process is relatively cumbersome and time-consuming during assembly and maintenance. Therefore, providing a connection device that facilitates installation and disassembly and improves the efficiency of endoscope main unit shell assembly, disassembly, and maintenance is an urgent problem to be solved in this field. Utility Model Content

[0004] The main purpose of this invention is to provide a quick-release device for an endoscope host, which aims to solve the problems of complex installation, inconvenience in disassembly and maintenance of the endoscope host housing.

[0005] To achieve the above objectives, this utility model proposes a quick-release device for an endoscope host. The quick-release device includes: a ball head disposed on a first housing, the ball head having a limiting portion; and an elastic latching member fixed to a second housing, the elastic latching member including at least two opposing spring pieces, the relative free edges of the spring pieces defining an elastically deformable opening for the ball head to enter; the spring pieces protrude towards the insertion direction of the ball head and can elastically deform when the ball head enters the opening in the insertion direction to allow the ball head to pass through; after the ball head is inserted into place, the spring pieces rebound and abut against the front of the limiting portion, locking and positioning the ball head at the opening; wherein, in the spring-rebound state, the minimum width of the opening is less than the outer diameter of the limiting portion, to limit the insertion depth of the ball head and prevent it from dislodging when not subjected to external force.

[0006] Furthermore, the shrapnel forms a guide structure in the direction of the ball head being pulled out.

[0007] Furthermore, the guide structure is a funnel-shaped inclined surface.

[0008] Furthermore, the edges of the opening are rounded and chamfered to facilitate the insertion or removal of the ball head.

[0009] Furthermore, the spring is formed by punching and bending an elastic snap fastener.

[0010] Furthermore, the limiting part is a frustum-shaped structure with a gradually increasing diameter along the insertion direction.

[0011] Furthermore, the ball head is a ball head screw, which is fixedly connected to the adapter provided on the first housing through the tail thread.

[0012] An endoscope host, characterized in that the present invention also provides an endoscope host, wherein its housing components are interconnected by any of the quick-release devices described above.

[0013] Compared with existing technologies, the flexible quick-release device for connecting the endoscope host housing provided by this utility model combines the reliability of traditional screw connections with the convenience of snap-fit ​​connections. Its main advantages are as follows: through the interlocking of the ball head and the flexible snap-fit ​​component, the operator can complete the connection and separation of the housing in a short time without the use of any tools, overcoming the technical problems of frequent disassembly and assembly and long time consumption in traditional screw fixing methods; by adopting the mechanical interference principle that the outer diameter of the limiting part is greater than the minimum width of the opening after rebound, it is ensured that the ball head cannot be accidentally dislodged after snapping, and its vibration resistance and structural stability are significantly improved, fully protecting the safety of the precision components inside the endoscope host; when the ball head passes the opening, the spring rebounds and abuts against the limiting part, there is a clear tactile feedback, which allows the operator to clearly feel that the connection has been reliably completed, avoiding the problem of incomplete connection caused by the inability to confirm whether the snap-fit ​​is in place in traditional snap-fit ​​connections.

[0018] The core of this invention lies in providing a flexible quick-release device for connecting the endoscope main unit housing, which aims to solve the problems of complex installation, inconvenience in disassembly and maintenance of the endoscope main unit housing.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figure 1 , Figure 2 As shown, this embodiment of the invention discloses a quick-release device for an endoscope host, which fixes the first housing 1 and the second housing 2 of the endoscope host, for example, fixing the front housing and the top cover of the endoscope host. The quick-release device is disposed between the front housing and the top cover, and includes a ball head 3 and an elastic latch 4. In this embodiment, the ball head 3 is specifically a ball head screw. The ball head screw has a spherical head at its front end along the insertion direction. The main function of setting the head as a spherical surface is to allow for smooth insertion or removal from the opening 41 provided on the elastic latch. The tail of the ball head 3 is provided with a limiting part. 31. The limiting part 31 is a frustum-shaped structure with a diameter that gradually increases along the insertion direction. When the ball head screw is inserted into the elastically expandable opening 41 of the elastic buckle 4, the elasticity of the elastically expandable opening forms a reliable mechanical stop. At this time, the opening 41 and the limiting part 31 are engaged, thereby limiting the insertion depth of the ball head 3. A threaded structure is provided on the bottom side of the frustum. The ball head screw is fixed by being screwed into an adapter 5 and fixedly installed on the inner side of the first housing 1 by the adapter 5. The adapter 5 can be fixed to the first housing 1 by adhesive or screws.

[0021] In this embodiment, the elastic buckle 4 is a sheet metal made of stainless steel or other metal sheet metal materials. Its fatigue strength, creep resistance, and corrosion resistance are stronger than those of plastic buckles. It can withstand repeated insertion and removal operations while maintaining good elasticity and locking force, thus solving the problems of easy aging and fatigue breakage of plastic buckles. The sheet metal is preferably elongated, with flat mounting portions on its left and right sides, and is fixed to the threaded posts 21 pre-set inside the second housing 2 by fastening screws. The middle of the sheet metal has an outwardly protruding protrusion formed by stamping; specifically, the elastic buckle 4 is roughly folded into a triangle.

[0022] To limit the insertion depth of the ball head screw and prevent it from coming out without external force, an elastically expandable opening 41 is provided in the elastic fastener 4. This opening 41 is composed of two opposing spring tabs 42. Through a punching process, two parallel vertical slits and a horizontal slit connecting the tops of the two slits are cut on the top of the protrusion, thus forming two spring tabs 42 on the elastic fastener 4. These two spring tabs 42 are positioned opposite each other, and their ends (i.e., free ends) are bent away from each other, thus forming an outwardly turned protrusion 43. The inner surfaces of these two protrusions 43 together form a funnel-shaped guide structure. Through the bending process, the opening 41 is naturally formed between the two spring tabs 42. In addition, in order for the ball head to pass smoothly through the opening 41, the edges of the opening 41 are rounded and chamfered.

[0023] To ensure a more secure installation of the first housing 1 and the second housing 2, at least two elastic quick-release devices as described in this embodiment are provided between them. When it is necessary to close the first housing 1 and the second housing 2 for installation, the operator can quickly install the first housing 1 by aligning it with the second housing 2 and pressing it down. When the ball head 3 is aligned with the opening 41 and the two spring pieces 42 are forced to overcome elastic stress and undergo elastic bending deformation in a direction away from each other under the action of the squeezing force, thereby expanding the effective width of the opening 41. When the spherical surface at the front end of the ball head 3 completely passes through the preset width point of the opening 41, the spring piece 42 will quickly rebound due to the elasticity of its own material, returning to its initial or near-initial state. At this time, the inner side of the spring piece 42 (i.e., the protrusion 43) tightly abuts against the front part of the frustum-shaped structure of the limiting part 31. Therefore, when the spherical surface completely passes through the opening and the spring piece 42 rebounds and abuts against the limiting part 31, there will be a clear tactile feedback, allowing the operator to clearly perceive that the connection has been reliably completed, avoiding the problem of insecure connection caused by the inability to confirm whether the connection is properly engaged in traditional snap-fit ​​connections.

[0024] Because the outer diameter of the limiting part 31 is set to be greater than the minimum width of the opening 41 of the spring 42 in the free rebound state, mechanical interference is formed. This interference means that the ball head 3 cannot be pulled out of the opening 41 in reverse unless it receives a sufficiently large external force to force the spring 42 to deform again. This securely and reliably connects the first housing 1 and the second housing 2 together and limits the final insertion depth. Its vibration resistance and structural stability are significantly improved, which fully protects the safety of the precision components inside the endoscope host.

[0025] During disassembly, simply apply sufficient force to pull out the first housing 1 with the ball head 3 installed. The ball head 3 will then force the spring piece 42 to deform again, thus smoothly exiting from the opening 41 and achieving rapid separation. The operator can complete the connection and separation of the housing in a short time without using any tools, overcoming the technical problems of frequent disassembly and assembly and long time consumption in the traditional screw fixing method.

[0026] In addition, the device has a compact structure that can be cleverly hidden inside the endoscope main unit housing, which not only makes the product look simpler and more beautiful, but also avoids the problem of dust accumulation and difficulty in cleaning of external screw holes, and provides greater freedom for the industrial design of the housing.

[0027] This embodiment also provides an endoscope host, whose housing components are interconnected via the aforementioned quick-release device.

[0028] The above description is only a preferred embodiment of the present invention and should not be used to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
