[0064] As described in the background, the handles of current inspection mirrors are typically one-piece structures that are disposable and discarded after use, which is wasteful and costly. Furthermore, the internal structure of the handle is poorly arranged and compact, affecting the user experience of the inspection mirror.

[0065] In response to the above technical problems, an embodiment of the present application provides an endoscope and an inspection device, which includes an operating part, a handle, a catheter assembly and a dispenser. The operating part has an internal cavity. The handle includes a first gripping part and a second gripping part, the first gripping part and the operating part are an integrated structure, and the second gripping part is detachably located on the first gripping part. One end of the catheter assembly is inserted into the internal cavity, and the catheter assembly is connected to the internal cavity. The dispenser is located in the internal cavity and is sleeved on the catheter assembly in the axial direction of the catheter assembly. The inspection device includes the above-mentioned endoscope. In this way, the present application can design an endoscope and an inspection device, which makes the first gripping part and the operating part an integrated structure, and the second gripping part and the first gripping part are detachably arranged, so that the second gripping part is reusable and the structural stability of the entire handle is improved.

[0066] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0067] The embodiments of the present application provide an endoscope and inspection device. The first grip and operating portion are integrally formed, and the second grip is detachably mounted on the first grip. This allows the second grip to be reusable and improves the structural stability of the entire handle. The specific structures of the endoscope and inspection device provided by the embodiments of the present application are described below in conjunction with the accompanying drawings.

[0068] refer to Figure 1 、 Figure 2 as well as Figure 3 In a first aspect, an embodiment of the present application provides an endoscope 100. The endoscope 100 may include an operating portion 200, a handle 300, a catheter assembly 400, and a liquid dispenser 500. In an embodiment of the present application, the operating portion 200 may have an internal cavity 210, and various components may be located in the internal cavity 210. In a possible implementation, as Figure 2 As shown, the handle 300 may include a first grip portion 310 and a second grip portion 320. The first grip portion 310 may be integrally formed with the operating portion 200, i.e., the first grip portion 310 may be in communication with the operating portion 200. The second grip portion 320 may be detachably located on the first grip portion 310. The first grip portion 310 may have a recess 250 on a side facing the second grip portion 320, so that the second grip portion 320 can engage with the recess 250, thereby forming a single unit with the first grip portion 310, thereby facilitating the operator's gripping of the endoscope 100. It will be appreciated that the detachable arrangement of the second grip portion 320 from the first grip portion 310 makes the second grip portion 320 reusable. After the endoscope 100 is used, the operating portion 200 and the first grip portion 310 are disposed of as a single-use consumable, while the second grip portion 320 can be retained for reuse, reducing the cost of use. Due to the reusability of the second grip portion 320, more integrated functions can be designed on the second grip portion 320 for signal input and control.

[0069] Continue to refer Figure 3 On the basis of the above embodiment, one end of the catheter assembly 400 can be inserted into the internal cavity 210, so that the catheter assembly 400 is connected to the internal cavity 210. The other end of the catheter assembly 400 can extend from the operating part 200 for insertion into the human body for inspection. Figure 3 As shown, the liquid dispenser 500 can be located in the internal cavity 210, and the liquid dispenser 500 can be sleeved on the catheter assembly 400 in the axial direction of the catheter assembly 400. It can be understood that the liquid dispenser 500 can fix the position of the catheter assembly 400, and the liquid dispenser 500 has a liquid channel 510 inside, which is connected to the catheter assembly 400.

[0070] Continue to refer Figure 3 On the basis of the above embodiment, the endoscope 100 may further include: a sealing sleeve 600 and a liquid tube assembly 700. In one possible implementation, the sealing sleeve 600 may be an integrated structure, and the sealing sleeve 600 may be sleeved on at least a portion of the liquid dispenser 500. It is understandable that the sealing sleeve 600 is connected to the liquid dispenser 500, wherein the sealing sleeve 600 has a liquid inlet end 610 and a liquid outlet end 620 for liquid circulation, thereby serving as a liquid inlet channel and a liquid outlet channel. In the embodiment of the present application, as Figure 4 As shown, the liquid pipe assembly 700 can be located in the first grip portion 310 and connected to the sealing sleeve 600. The liquid pipe assembly 700 can include a liquid inlet pipe 710 and a liquid outlet pipe 720. The liquid inlet pipe 710 is connected to the liquid inlet end 610, and the liquid outlet pipe 720 is connected to the liquid outlet end 620.

[0071] Continue to refer Figure 2 as well as Figure 3 Based on the above embodiment, the liquid dispenser 500 may have a liquid inlet 520 and a liquid outlet 530 for liquid circulation, and the liquid inlet 520 and the liquid outlet 530 are located on the same side of the liquid dispenser 500. The liquid inlet 520 is connected to the liquid inlet end 610, and the liquid outlet 530 is connected to the liquid outlet end 620. In this way, the liquid inlet 520 on the liquid dispenser 500 is connected to the liquid inlet end 610 of the sealing sleeve 600 and the liquid inlet pipe 710 in the liquid pipe assembly 700, and the liquid outlet 530 on the liquid dispenser 500 is connected to the liquid outlet end 620 of the sealing sleeve 600 and the liquid outlet pipe 720 in the liquid pipe assembly 700. The liquid in the liquid inlet tube 710 enters the liquid channel 510 along the liquid inlet port 520 through the liquid inlet end 610 and then into the catheter assembly 400. After inspection inside the human body, the liquid flows back to the liquid outlet 530 through the liquid outlet end 620 along the liquid outlet tube 720 and flows out of the operating part 200.

[0072] Continue to refer Figure 3 Based on the above embodiment, the endoscope 100 further includes a sealing ring 630. The sealing ring 630 is located in the gap between the liquid dispenser 500 and the sealing sleeve 600, and can be used to isolate the liquid inlet 610 from the liquid outlet 620. In one possible implementation, the outer surface of the liquid dispenser 500 has a plurality of spaced-apart protrusions 540, with the protruding portion of each protrusion 540 contacting the inner surface of the sealing sleeve 600. The sealing ring 630 can be located between every two protrusions 540. By providing the sealing ring 630, the liquid inlet and outlet pipelines can be further isolated.

[0073] Continue to refer Figure 3On the basis of the above embodiment, the endoscope 100 may further include: a gyroscope assembly 800. In one possible implementation, the gyroscope assembly 800 is located at one end of the dispenser 500 close to the catheter assembly 400, and the gyroscope assembly 800 may be located in the internal cavity 210 and sleeved on the catheter assembly 400. Furthermore, the gyroscope assembly 800 may include a gyroscope circuit board 810 and a shielding member 820. The shielding member 820 may be covered on the gyroscope circuit board 810, and the shielding member 820 may be used to shield the gyroscope circuit board 810 from external interference. It is understandable that the endoscope 100 generally also has a camera module (not shown in the figure), which assists in observing the inside of the human body and collects images through the camera module. The provision of the gyroscope assembly 800 can perform real-time correction on the images collected by the camera module, making it easier for the operator to observe.

[0074] Continue to refer Figure 3 Based on the above embodiment, the endoscope 100 may further include an end cap 830. The end cap 830 may be located between the gyroscope circuit board 810 and the liquid dispenser 500. One end of the end cap 830 is fixed to the gyroscope circuit board 810, and the other end of the end cap 830 is connected to the liquid dispenser 500. It is understood that the end cap 830 can be used to fix the gyroscope circuit board 810 and the shielding member 820. The shielding member 820 may cover one side of the gyroscope circuit board 810, while the end cap 830 may cover the other side of the gyroscope circuit board 810, thereby further shielding the gyroscope circuit board 810 from external interference.

[0075] Based on the above embodiments, it can be understood that since the sealing sleeve 600 is an integrated structure and the liquid inlet end 610 and the liquid outlet end 620 are both opened on the same sealing sleeve 600, the internal space is saved, the internal structure is more compact, and sufficient space is provided for the gyroscope assembly 800, so that the entire endoscope 100 tends to be miniaturized.

[0076] Continue to refer Figure 3Based on the above embodiment, the endoscope 100 may further include a plug assembly 900. The plug assembly 900 may be located below the dispenser 500. Furthermore, the plug assembly 900 may include a plug circuit board 910, a plug housing 920, and a plug sleeve 930. In one possible implementation, one end of the plug circuit board 910 may be inserted into the plug housing 920, while the other end of the plug circuit board 910 may extend from the operating portion 200, thereby enabling the plug circuit board 910 to serve as the primary component for signal transmission from the camera module. It is understood that the plug sleeve 930 and the plug housing 920 are both located within the internal cavity 210 of the operating portion 200, and the plug sleeve 930 may be located in the gap between the plug housing 920 and the operating portion 200, thereby enabling the plug sleeve 930 to fill the assembly gap between the plug housing 920 and the operating portion 200 to secure the position of the plug circuit board 910 and the plug housing 920. The plug housing 920 can secure the position of the plug circuit board 910 and provide protection for the plug circuit board 910. In one possible implementation, the plug circuit board 910 can be a Type-C male connector board with excellent data transmission capabilities. In addition, the plug sleeve 930 and the plug housing 920 position the plug circuit board 910, ensuring accurate alignment each time the plug circuit board 910 is inserted, enabling quick insertion and removal of the plug circuit board 910 and reducing wear during insertion and removal.

[0077] refer to Figure 3 as well as Figure 4 Based on the above embodiment, the outer surface of the sealing sleeve 600 may be provided with a wire groove 640, which can be used to retain the cable. In one possible implementation, there may be multiple wire grooves 640, and the wire grooves 640 may be located at different locations on the outer surface of the sealing sleeve 600, but this is not limited to this embodiment of the present application. The wire groove 640 may have a protrusion 641 and a recess 642. The cable is wrapped around the protrusion 641 and engages with the recess 642, so that the cable fits into the wire groove 640 and is positioned in the wire groove 640. In this embodiment of the present application, the gyroscope circuit board 810 and the plug-in circuit board 910 can be electrically connected via a cable. To make the cable routing more aesthetically pleasing and prevent interference with other components, the cable can be wrapped around the wire groove 640 on the outer surface of the sealing sleeve 600 to retain the cable. In this way, the gyroscope circuit board 810 and the plug-in circuit board 910 can be electrically connected via the cable through the wire groove 640.

[0078] Continue to refer Figure 3Based on the above embodiment, the endoscope 100 may further include: a one-way valve 550. The one-way valve 550 may be located at the end of the dispenser 500 that faces away from the gyroscope assembly 800. It is understood that the one-way valve 550 can be used to prevent the liquid in the catheter assembly 400 from flowing out of the operating portion 200 along the dispenser 500. In one possible implementation, the one-way valve 550 may be provided with an opening (not shown in the figure) for instruments to pass through. For example, the one-way valve 550 may be a duckbill valve. The one-way valve 550 may be a two-flap duckbill valve, a four-flap duckbill valve, or a six-flap duckbill valve. The two-flap duckbill valve may have a straight opening, while the four-flap duckbill valve may have a cross-shaped opening. In this way, instruments can pass through the one-way valve 550 and enter the internal cavity 210 along the opening, and the one-way valve 550 is in an open state at this time. In a scenario where no instrument enters the internal cavity 210 , the one-way valve 550 is in a closed state, and the one-way valve 550 has the function of preventing liquid from flowing back.

[0079] Continue to refer Figure 3 Based on the above embodiment, the endoscope 100 may further include a knob 220 and a plug 222. The knob 220 may be located at the end of the operating portion 200 facing away from the catheter assembly 400, and may be rotatably connected to the operating portion 200. The end of the knob 220 facing the dispenser 500 may be fixedly connected to the dispenser 500. When the knob 220 is rotated, the dispenser 500 rotates together, thereby driving the catheter assembly 400 to rotate. At this time, the sealing sleeve 600 and the liquid tube assembly 700 do not rotate relative to the dispenser 500. In one possible implementation, the knob 220 may have a first channel 221 defined within it for instruments to pass through. Thus, instruments can pass through the first channel 221 of the knob 220, along the opening of the one-way valve 550, into the liquid channel 510 of the dispenser 500, and cooperate with the catheter assembly 400.

[0080] Continue to refer Figure 3 Based on the above embodiment, the plug 222 can be located on the side of the one-way valve 550 facing away from the dispenser 500, and one end of the plug 222 is inserted into the knob 220, thereby achieving a seal between the plug 222 and the knob 220. In this way, the plug 222 can cooperate with the knob 220 to prevent external air from entering the internal cavity 210, further achieving a seal.

[0081] Based on the above embodiment, it can be understood that the operating portion 200 may have a limiting structure (not shown in the figure) inside, and the limiting structure can cooperate with the knob 220 to limit the rotation of the knob 220 and prevent the knob 220 from rotating without limit. In one possible implementation, the limiting structure may include a first baffle and a second baffle. The first baffle and the second baffle are located inside the operating portion 200, and the angle between the first baffle and the second baffle is less than or equal to 350°. In this way, the limiting structure can abut against the first baffle and the second baffle during the rotation of the knob 220, thereby limiting the rotation angle of the knob 220 to 350°, making the rotation angle controllable.

[0082] Continue to refer Figure 3 Based on the above embodiment, the catheter assembly may include an outer tube 410 and an inner tube 420. The outer tube 410 may be sleeved onto the inner tube 420, forming a second channel (not shown) between the outer tube 410 and the inner tube 420 for liquid circulation. The second channel is connected to the first channel 221, and liquid can circulate through the first channel 221, the liquid channel 510, and the second channel in the knob 220. It is understood that the inner tube 420 can be used to pass through an instrument. The instrument passes through the first channel 221 of the knob 220 and along the opening of the one-way valve 550 into the liquid channel 510 of the dispenser 500, and then enters the interior of the inner tube 420. In one possible implementation, after entering the interior of the inner tube 420, the instrument can be extended from the end of the inner tube 420 away from the dispenser 500 to perform corresponding operations on the human body. A camera module may be provided at the end of the outer tube 410 away from the dispenser 500 to capture images.

[0083] Continue to refer Figure 3 Based on the above embodiment, the endoscope 100 may further include: a first seal 260 and a second seal 270. The first seal 260 may be located between the operating portion 200 and the outer tube 410, and the first seal 260 may be used to fill the gap between the operating portion 200 and the outer tube 410. The second seal 270 may be located at the end of the one-way valve 550 facing the knob 220, and the second seal 270 may be used to seal the first channel 221 of the knob 220 and the opening of the one-way valve 550, thereby further achieving sealing during the insertion of the instrument. In one possible implementation, both the first seal 260 and the second seal 270 may be made of soft silicone material.

[0084] Continue to refer Figure 1 as well as Figure 2On the basis of the above embodiment, the endoscope 100 may further include: a housing 1000. The housing 1000 may be formed as a whole by the first gripping portion 310 and the operating portion 200. Furthermore, the housing 1000 may include: a first shell 230 and a second shell 240. The first shell 230 and the second shell 240 are detachably connected. A recess 250 may be formed at the connection between the first shell 230 and the second shell 240, so that the second gripping portion 320 cooperates with the recess 250, and the second gripping portion 320 is connected to the first gripping portion 310 by means of a snap fit, a mechanical connection, or the like.

[0085] Continue to refer Figure 3 On the basis of the above embodiment, the endoscope 100 may further include: a push button 311 and a locking piece 312. The push button 311 and the locking piece 312 may be provided at the end of the first grip portion 310 facing away from the operating portion 200. In one possible implementation, one end of the push button 311 abuts against the locking piece 312, and the other end of the push button 311 is exposed on one side of the first grip portion 310. The portion of the locking piece 312 abutting against the push button 311 is located inside the first grip portion 310, and at least a portion of the locking piece 312 may be exposed on the other side of the first grip portion 310 during the locking process. The portion of the locking piece 312 exposed from the first grip portion 310 may be used to be fixed to the second grip portion 320. In a possible implementation, a slot (not shown) may be provided on the side of the second grip portion 320 facing the first grip portion 310, and the slot may be used to engage with the portion of the locking plate 312 exposed from the first grip portion 310, thereby achieving a fixed connection between the first grip portion 310 and the second grip portion 320. It is understandable that, in combination with Figure 2From the perspective of the push button 311, the locking plate 312 cooperates with each other to unlock or lock the second grip portion 320 and the first grip portion 310, thereby achieving a detachable connection between the second grip portion 320 and the first grip portion 310. In this embodiment of the present application, a sliding groove 313 is defined on the side of the push button 311 exposed from the first grip portion 310, and the push button 311 can slide back and forth on the sliding groove 313. The end of the sliding groove 313 closest to the operating portion 200 is a first position 314, and the end of the sliding groove 313 away from the operating portion 200 is a second position 315. When locking the first grip portion 310 and the second grip portion 320, the push button 311 is pushed to the first position 314, so that at least a portion of the locking piece 312 is exposed from the first grip portion 310 and engages with the second grip portion 320 during the pushing of the push button 311, thereby preventing the second grip portion 320 from freely moving on the first grip portion 310, thereby achieving the locking function. When unlocking the first grip portion 310 and the second grip portion 320, the push button 311 is pushed to the second position 315, so that the portion of the locking piece 312 exposed from the first grip portion 310 returns to the inside of the first grip portion 310 during the pushing of the push button 311, thereby moving the locking piece 312 away from the position engaged with the second grip portion 320 and returning to the initial position, thereby releasing the second grip portion 320 from the state of being unable to move freely, thereby achieving the unlocking function. It is understandable that the locking method provided in the present application includes but is not limited to the push button 311 and the locking piece 312 , and also includes other structures that can replace the push button 311 and the locking piece 312 .
