[0034] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0035] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0036] In each embodiment of the present application, "proximal end" and "distal end" refer to the position of each component relative to the user in the use environment, wherein the end closer to the user is designated as the "proximal end" and the end farther from the user is designated as the "distal end".

[0037] The inventive concept of the present application is described here:

[0038] With the development of science and technology, medical equipment has gradually become electrified. Although electrified medical equipment has better performance to assist surgeons in performing more in-depth examinations or surgeries, it will require electrified medical equipment to be connected to a power source.

[0039] After each use, the operator needs to disinfect the medical equipment, and the electrified medical equipment is no exception. In this process, the medical equipment needs to be immersed in disinfectant. However, there are many electrical connection parts in the connector of the electrified medical equipment, and these electrical connection parts are easily damaged when immersed in disinfectant. The existing waterproof accessories need to be disassembled and assembled repeatedly. Specifically, when the operator uses the medical equipment, the waterproof accessories need to be removed before connecting with the terminal equipment or other medical equipment. When the operator is finished using it, the waterproof accessories need to be installed to disinfect the medical equipment. However, during this disassembly and assembly process, the connection parts of the waterproof accessories and the parts of the medical equipment that need to be waterproof will still be exposed to the environment, which may be contaminated by the external environment during this period. Once the waterproof accessories are connected to the parts of the medical equipment that need to be waterproof, even if the medical equipment is disinfected, the waterproof accessories and the parts of the medical equipment sealed by the waterproof accessories cannot be disinfected. When the waterproof accessories are used again and removed, other parts of the medical staff such as the hands will come into contact with the unsterilized parts, which may cause cross infection.

[0040] Based on this, the inventor provides a handle connector watertight kit, a waterproof connector and an endoscope, wherein the handle connector watertight kit can be directly installed at the connector of the medical device, and the handle connector watertight kit is configured to be sealed in a natural state, that is, the connector of the medical device installed in the handle connector watertight kit is in a sealed state with the external environment, and when the medical device equipped with the handle connector watertight kit is immersed in disinfectant for disinfection, the disinfectant will not invade the interior of the handle connector watertight kit. When the connector of the medical device needs to be connected to a terminal device or other medical device, the handle connector watertight kit can be pressed to connect the connector of the medical device installed in the handle connector watertight kit to the outside world, so that the connector of the medical device can be connected to the terminal device or other medical device.

[0041] The following is combined with Figures 1 to 8, a handle connector watertight kit 1, a waterproof connector 2 and an endoscope provided in the present application are described in detail through specific embodiments and their application scenarios.

[0042] See also Figure 1 An embodiment of the present application provides a handle connector watertight kit 1, which can be used for an endoscope. The endoscope includes a connector provided with a handle portion. The handle connector watertight kit can be installed on the connector and is used to selectively seal the connector.

[0043] Please also see Figure 1-Figure 3 The handle connector watertight kit provided in the embodiment of the present application may include: a first tube body 10, a second tube body 20, a reset structure 40 and a seal 50, wherein the second tube body 20 can be slidably embedded in the first end of the first tube body 10, and the reset structure 40 and the seal 50 can both be arranged in the first tube body 10.

[0044] The embodiment of the present application does not limit the specific structure of the first tube body 10 and the second tube body 20. For example, in some embodiments, the first tube body 10 and the second tube body 20 can be configured to have a circular cross-section, which can be adapted to most connectors. It is understandable that in some other embodiments, the specific structure of the first tube body 10 and the second tube body 20 can also be configured according to actual conditions and adapted to the connector.

[0045] For details, please also refer to Figure 2 and Figure 3 The first tube body 10 may include a first main body 110 and a first structural portion 111. The first structural portion 111 may be disposed on the first main body 110 and extend radially inward to form a stepped structure inside the first main body 110. The first structural portion 111 may be disposed at the end of the first main body 110. The first tube body 10 may be used to accommodate and install a connector, and after the connector is installed in the first main body 110 of the first tube body 10, the installation location may be in a sealed state. It is understandable that the present embodiment of the application does not limit the sealing method of the installation location. For example, it may be sealed in the form of an interference fit, or a functional part for tightening may be disposed on the outer surface of the first tube body 10 to achieve sealing. The specific configuration may be based on actual conditions and is not limited here.

[0046] Please continue reading Figure 2 and Figure 3 The second tube body 20 may include a main body and a second structural portion 220 . The second structural portion 220 may be disposed on the second main body 210 and extend radially inward to form a stepped structure inside the second main body 210 . The second structural portion 220 may be disposed at an end of the second main body 210 .

[0047] For details, please refer to Figure 3 In this embodiment, the first structure portion 111 can be disposed at the lower end of the first body 110 close to the second tube body 20 , and the second structure portion 220 can be disposed at the upper end of the second body 210 close to the first tube body 10 .

[0048] In this embodiment, the first structure part 111, the second structure part 220 and the second body 210 are surrounded together to form the installation space 30, and the installation space 30 can be used to install the sealing member 50. Specifically, in this embodiment, the first structure part 111 and the second structure part 220 can constitute the step surfaces at both ends of the installation space 30, the second body 210 can constitute the side of the installation space 30, and the sealing member 50 can be abutted between the first structure part 111, the second structure part 220 and the second body 210, and be restricted between the first structure part 111, the second structure part 220 and the second body 210.

[0049] Please continue reading Figure 2 and Figure 3 The seal 50 may be disposed in the installation space 30, and the seal 50 may be used to seal the first tube body 10 and the second tube body 20. Specifically, in this embodiment, the seal 50 may be configured such that when the axial dimension of the seal 50 is compressed, the radial dimension expands to seal the first tube body 10 and the second tube body 20.

[0050] Please also see Figure 4 and Figure 5 In a more specific embodiment, the seal 50 can be set as a hollow cylindrical structure. When the seal 50 is in a natural state, the middle part of the seal 50 is connected. When the seal 50 is in an axial compression state, the axial dimension of the seal 50 will be reduced, and the seal 50 will be deformed, so that the hollow part of the seal 50 is gathered, thereby increasing the radial dimension of the seal 50 and making the seal 50 closed. It should be noted that the embodiment of the present application does not limit the aforementioned gathering method. For example, in one embodiment, all parts around the middle of the seal 50 can be gathered towards the middle, or some areas can be gathered towards the middle and finally closed. The specific setting can be based on the actual situation and is not limited here.

[0051] Please refer again Figure 2 and Figure 3, the reset structure 40 can be arranged between the first tube body 10 and the second tube body 20, and the reset structure 40 can be used to drive the second tube body 20 to move in the direction of extending out of the first tube body 10, so as to reduce the axial dimension of the installation space 30. It can be understood that the radial dimension of the installation space 30 does not change at this time. In this embodiment, the reset structure 40 can be arranged inside the first tube body 10, and provide a force to compress the axial dimension of the sealing member 50, so that in a natural state, the sealing member 50 seals the first tube body 10 and the second tube body 20. In addition, since the reset structure 40 provides a force to compress the axial dimension of the seal 50 in the natural state, the radial dimension of the seal 50 will expand in the natural state, so that the seal 50 can squeeze the side wall of the second tube body 20 in the natural state, so that the second tube body 20 and the first tube body 10 can fit more closely, which is beneficial to improve the sealing degree between the second tube body 20 and the first tube body 10, and prevent pollutants in the external environment from entering the first tube body 10 through the gap between the second tube body 20 and the first tube body 10.

[0052] It should be noted that the embodiment of the present application does not limit the specific form and setting mode of the reset structure 40. For example, in one embodiment, the reset structure 40 can be set as a coil spring, and in another embodiment, the reset structure 40 can also be set as an air bag, etc. When the reset structure 40 is set as a spring, one end of the reset structure 40 can be connected to the second structure part 220, and the other end can be set on the inner wall of the first body 110. In a preferred embodiment, the first tube 10 can also include a third structure part 112. The setting mode of the third structure part 112 can refer to the setting mode of the first structure part 111, and will not be repeated here. In this embodiment, the third structure part 112 can be set on the side of the first structure part 111 away from the second tube 20, and the other end of the reset structure 40 can be connected to the third structure. That is to say, in this embodiment, there is a gap 113 between the second structure part 220 and the third structure part 112, and the reset structure 40 can be set in the gap 113. This is beneficial to improving the stability of the reset structure 40 and the service life of the reset structure 40, thereby improving the service life of the entire handle connector watertight kit 1.

[0053] As mentioned above, since the seal 50 is arranged in the installation space 30, and since the volume of the seal 50 can be considered constant within the bearing range, when the axial dimension of the installation space 30 is compressed, the axial dimension of the seal 50 will also be compressed, which will cause the radial dimension of the seal 50 to expand, thereby playing the role of sealing the first tube body 10 and the second tube body 20.

[0054] The embodiment of the present application also provides another structure of the second tube body 20. In this embodiment, the second tube body 20 may only include the second body 210, that is, compared with the previous embodiment, the second tube body 20 does not have the second structure portion 220. In this embodiment, the first body 110, the first structure portion 111, the third structure portion 112 and the second tube body 20 together surround and form the installation space 30. The sealing member 50 may be connected to the inner wall of the second tube body 20. At this time, the installation space 30 and the gap 113 are the same structure, and the sealing member 50 and the reset structure 40 may be simultaneously arranged in the installation space 30. In this embodiment, the structure of the second tube body 20 is simpler, which is conducive to reducing production costs.

[0055] It should be noted that no matter what structure the second tube body 20 adopts, the embodiments of the present application do not limit the relative positional relationship between the first tube body 10 and the second tube body 20. For example, in some embodiments, the second tube body 20 can partially extend out of the first tube body 10. For example, in other embodiments, the second tube body 20 can be completely embedded in the first tube body 10, etc. The specific setting can be based on actual conditions and is not limited here.

[0056] When the second tube body 20 extends out of the first tube body 10, the extended portion can contact the external environment and compress the reset structure 40, so that the first tube body 10 and the second tube body 20 are connected. Figure 1 , Figure 2 and Figure 6 In a specific usage scenario, the operator can directly place the second tube 20 against the plug port of the terminal device 3 and use it to push the first tube 10. At this time, the second tube 20 is squeezed and slid into the first tube 10, and the reset structure 40 is squeezed, and finally the first tube 10 and the second tube 20 are connected, and then the connector in the handle connector watertight kit 1 can be connected to the terminal device 3. When the operator is finished using it, the connector can be directly pulled out from the terminal device 3. At this time, the reset structure 40 loses the effect of external force, the seal 50 recovers its deformation, and seals the first tube 10 and the second tube 20. At this time, the used medical device can be directly immersed and disinfected.

[0057] Please also see Figure 1 , Figure 2 and Figure 7Furthermore, the handle connector watertight kit 1 provided in the embodiment of the present application may also include: a pushing component 60, which can be connected to the second tube body 20, and the pushing component 60 can pass through the first tube body 10 and at least partially extend out of the surface of the first body 110, so that the operator can operate the pushing component 60, and by changing the position of the pushing component 60, for example, the operator can push the pushing component 60, thereby driving the second tube body 20 to move, and ultimately changing the axial size of the installation space 30.

[0058] Specifically, in this embodiment, the pushing assembly 60 may include: a connecting rod 610 and a pushing block 620, wherein the connecting rod 610 can be arranged on the second tube body 20 and can be specifically connected to the second body 210, the first tube body 10 can be provided with a guide groove 114, wherein the guide groove 114 can be specifically opened in the first body 110, the pushing block 620 can be slidably arranged in the guide groove 114, and connected to the connecting rod 610. In this embodiment, at least a portion of the pushing block 620 extends out of the surface of the first body 110, which can further facilitate the operator's operation.

[0059] Please refer again Figure 1 , Figure 2 and Figure 6 In a specific use scenario, the operator can push the push block 620, and make the second tube body 20 slide into the first tube body 10, and squeeze the reset structure 40, finally making the first tube body 10 and the second tube body 20 conductive, and then the connector in the handle connector watertight kit 1 can be connected to the wiring port of the terminal device 3. When the operator is finished using, the push block 620 can be directly pushed to make the second tube body 20 slide out of the first tube body 10, the second tube body 20 can abut against the terminal device 3, and the wiring port of the terminal device 3 is separated from the connector in the handle connector watertight kit 1. At this time, the reset structure 40 loses the effect of external force, the seal 50 recovers its deformation, and seals the first tube body 10 and the second tube body 20, and the used medical device can be directly immersed and disinfected.

[0060] See also Figure 7 Furthermore, in one embodiment, an anti-skid structure may be provided between the connecting rod 610 and the push block 620, and the anti-skid structure may help increase the friction between the connecting rod 610 and the push block 620, thereby facilitating the operator's operation. In addition, an anti-skid structure may also be provided on the outer surface of the push block 620, and the anti-skid structure may help increase the friction between the operator's hand and the push block 620, thereby facilitating the operator's operation.

[0061] The embodiments of the present application do not limit the specific form of the anti-slip structure. For example, in one embodiment, the anti-slip structure can be a damping member arranged between the connecting rod 610 and the push block 620. For example, in another embodiment, the contact surface of the connecting rod 610 and the push block 620 can be roughened to form an anti-slip structure. The specific arrangement can be based on actual conditions and is not limited here.

[0062] Please also see Figure 1 , Figure 2 and Figure 7 In addition, in some embodiments, the pushing assembly 60 may further include a fastener 630. In this embodiment, the pushing block 620 may be provided with two pushing blocks 620 which may be radially arranged along the surface of the first body 110, which may further facilitate the operator to push the pushing block 620 and may enable the operator to be more balanced in the process of pushing the pushing block 620 to drive the second tube 20 to move. The fastener 630 may surround the outer surface of the first tube 10, and the two ends of the fastener 630 may be connected to the two pushing blocks 620 respectively, so that the movement of the two pushing blocks 620 may be kept synchronous.

[0063] Furthermore, in one embodiment, the fastener 630 may be preset with a force to make the push block 620 press against the connecting rod 610. That is to say, in this embodiment, the fastener 630 may increase the friction between the push block 620 and the connecting rod 610, which may further facilitate the operator's operation.

[0064] In summary, the watertight kit 1 of the handle connector provided in the embodiment of the present application is formed by sliding the second tube body 20 into one end of the first tube body 10, and surrounding the installation space 30 with the first tube body 10, and a seal 50 is arranged in the installation space 30, and the seal 50 is arranged to expand radially when the axial dimension of the seal 50 is compressed, so as to seal the first tube body 10 and the second tube body 20, so as to prevent water from entering the electrical components installed in the watertight kit of the handle connector. Specifically, a reset structure 40 is arranged between the first tube body 10 and the second tube body 20, and the reset structure 40 is used to provide a force to compress the axial dimension of the seal 50. When the reset structure 40 is subjected to the aforementioned reverse force and the reverse force is greater, the seal 50 can be unfolded, and at this time, the first tube body 10 and the second tube body 20 can be connected, so that the electrical components installed in the watertight kit of the handle connector can be connected to the outside through the first tube body 10. The handle connector watertight kit 1 provided in the embodiment of the present application can close the first tube body 10 and the second tube body 20 in a natural state. At this time, the electrical components installed in the handle connector watertight kit are sealed relative to the external environment. At this time, the electrical components can be directly immersed and disinfected together with the handle connector watertight kit, which simplifies the disinfection process and ensures that the electrical components installed in the handle connector watertight kit are not contaminated by the outside world.

[0065] See also Figure 8 The embodiment of the present application also provides a waterproof connector 2, which can include a wire body 21 and a handle connector watertight kit 1 as described above, and the handle connector watertight kit 1 is detachably arranged on the outer surface of the wire body 21. Since the waterproof connector 2 provided in the embodiment of the present application uses the handle connector watertight kit 1 as described above, the waterproof connector 2 provided in the embodiment of the present application can also simplify the disinfection process. Similarly, the embodiment of the present application also provides an endoscope, which can include the waterproof connector 2 as described above.
