[0056] like Figure 1 and Fig. 9 As shown, an embodiment provides an endoscope handle 1000 which can be applied in an endoscope system and can be used to achieve bending adjustment and self-locking of a scope 2000 in the endoscope system.

[0057] like Figures 1 to 3 , Fig. 9 As shown, the endoscope handle 1000 includes a housing assembly 100 , a rotating wheel 200 , a push handle 300 and a self-locking mechanism 400 .

[0058] The housing assembly 100 has an assembly cavity 101. The rotating wheel 200 is rotatably mounted in the assembly cavity 101. That is, the rotating wheel 200 is disposed in the assembly cavity 101 and can rotate relative to the housing assembly 100. The push handle 300 is disposed on a side of the housing assembly 100 away from the assembly cavity 101 and is in transmission connection with the rotating wheel 200. In the embodiment, the traction line 3000 connected to the mirror body 2000 can be connected to the peripheral side of the rotating wheel 200.

[0059] The self-locking mechanism 400 includes a driving assembly 410, a first clamping member 421 and a second clamping member 422. The first clamping member 421 and the second clamping member 422 are arranged on opposite sides of the rotating wheel 200. The first clamping member 421 and the second clamping member 422 can approach each other and cooperate to clamp the quasi-wheel 200, and the first clamping member 421 and the second clamping member 422 can move away from each other and release the rotating wheel 200. The driving assembly 410 is respectively connected to the first clamping member 421 and the second clamping member 422 in a transmission manner. The driving assembly 410 can be used to drive the first clamping member 421 and the second clamping member 422 to move closer to and away from each other.

[0060] In the embodiment, when the first clamping member 421 and the second clamping member 422 are close to each other and cooperate to clamp the rotating wheel 200, the friction resistance between the first clamping member 421, the second clamping member 422 and the rotating wheel 200 can be increased, preventing the rotating wheel 200 from rotating relative to the housing assembly 100. When the first clamping member 421 and the second clamping member 422 are away from each other and release the rotating wheel 200, the rotating wheel 200 can rotate relative to the housing assembly 100.

[0061] When it is necessary to lock the mirror body 2000, the operator can operate the driving assembly 410, and the driving assembly 410 drives the first clamping member 421 and the second clamping member 422 to approach each other and clamp the rotating wheel 200. Accordingly, the first clamping member 421 and the second clamping member 422 can cooperate to clamp the rotating wheel 200, so that the rotating wheel 200 is fixed relative to the housing assembly 100, and then the mirror body 2000 can be locked to prevent the bending angle and direction of the mirror body 2000 from changing arbitrarily.

[0062] When it is necessary to unlock the rotating wheel 200 to adjust the curvature of the mirror body 2000, the operator can also operate the driving assembly 410 to drive the first clamping member 421 and the second clamping member 422 to move away from each other to release the rotating wheel 200. The operator can drive the rotating wheel 200 to rotate by turning the push handle 300. During the rotation of the rotating wheel 200, the traction line 3000 connected to the mirror body 2000 can be driven to move to achieve the curvature adjustment of the mirror body 2000.

[0063] In the embodiment of the present application, when the rotating wheel 200 is locked by the self-locking mechanism 400, the first clamping member 421 and the second clamping member 422 can clamp the rotating wheel 200 from the opposite sides of the rotating wheel 200, so that the two sides of the rotating wheel 200 can be subjected to force, so that the rotating wheel 200 can be kept balanced, and the probability of the rotating wheel 200 being tilted can be reduced, thereby preventing the rotating wheel 200 from acting in the opposite direction on the first clamping member 421 (or the second clamping member 422), the traction line 3000, the mirror body 2000 and other structures due to uneven force, thereby reducing the possibility of damage to the first clamping member 421 (or the second clamping member 422), the traction line 3000 and the mirror body 2000, thereby extending the service life of the endoscope system.

[0064] like Figures 1 to 3 As shown, the housing assembly 100 may include a first housing 110 and a second housing 120. The first housing 110 and the second housing 120 are arranged opposite to each other and cooperate to form an assembly cavity 101. In some embodiments, the first housing 110 and the second housing 120 may be connected by screw connection or snap connection. A sealing ring 510 is also provided at the connection position between the first housing 110 and the second housing 120, which can achieve sealing at the connection position between the first housing 110 and the second housing 120, provide dustproof and waterproof protection for the structure inside the assembly cavity 101, reduce the probability of corrosion damage to the structure inside the assembly cavity 101, and extend the service life of the endoscope handle 1000.

[0065] like Figures 1 to 4In some embodiments, the endoscope handle 1000 further includes a mounting seat 600, which is disposed in the assembly cavity 101. The mounting seat 600 may include an integrated mounting seat body 610 and a first connecting shaft 620. The mounting seat body 610 may be generally in a plate-like structure, and the mounting seat body 610 may be fixedly connected to the first housing 110 by screws. The first connecting shaft 620 is located on the side of the mounting seat body 610 facing the second housing 120. One end of the first connecting shaft 620 away from the mounting seat body 610 is penetrated in the second housing 120, and protrudes relative to the side of the second housing 120 away from the assembly cavity 101. In some embodiments, the end of the first connecting shaft 620 protruding relative to the second housing 120 may be screwed with a limiting nut 730, and the limiting nut 730 may abut against the side of the second housing 120 away from the assembly cavity 101. It should be noted that the mounting seat body 610 and the first connecting shaft 620 are not limited to being an integrally formed structure, and the two may also be detachably fixedly connected, such as screw connection.

[0066] In the embodiment, the rotating wheel 200 is rotatably mounted on the mounting seat 600. In some embodiments, the rotating wheel 200 may include an integrated rotating wheel body 210 and a second connecting shaft 220. The rotating wheel body 210 may be connected to one end of the second connecting shaft 220, and the rotating wheel body 210 and the second connecting shaft 220 are coaxially arranged. In the embodiment, a wire groove may be provided on the peripheral side of the rotating wheel body 210, and one end of the traction line 3000 away from the mirror body 2000 may be accommodated in the wire groove and may be fixedly connected to the rotating wheel body 210. It should be noted that the rotating wheel body 210 and the second connecting shaft 220 are not limited to being an integrally formed structure, and the two may also be detachably fixedly connected, such as screw connection.

[0067] In some embodiments, the rotating wheel body 210 is disposed on a side of the mounting seat body 610 facing the first housing 110. The second connecting shaft 220 is located on a side of the rotating wheel body 210 facing the mounting seat 600. The second connecting shaft 220 may be sequentially disposed through the mounting seat body 610 and the first connecting shaft 620, and protrude relative to an end of the first connecting shaft 620 away from the mounting seat body 610. An end of the second connecting shaft 220 away from the rotating wheel body 210 may be fixedly connected to one end of the push handle 300 by means of screw connection or the like. It is understandable that the rotating wheel body 210 may rotate relative to the mounting seat body 610, and the second connecting shaft 220 may rotate relative to the first connecting shaft 620.

[0068] In some embodiments, the endoscope handle 1000 further includes a stop pin 710. The stop pin 710 may be perpendicular to the rotation axis L of the rotating wheel 200. One end of the stop pin 710 is fixedly connected to the second connecting shaft 220. The other end of the stop pin 710 may be inserted into the first connecting shaft 620 and protrude from the side of the first connecting shaft 620 away from the second connecting shaft 220. Accordingly, a travel groove 621 for the stop pin 710 to pass through is provided on the first connecting shaft 620. The travel groove 621 is extended along the rotation direction of the rotating wheel 200, and the stop pin 710 is slidably matched with the inner wall of the travel groove 621. Along the extension direction of the rotation axis L, the stop pin 710 contacts the two opposite side walls of the travel groove 621 to achieve axial limit between the stop pin 710 and the first connecting shaft 620, thereby achieving axial limit between the rotating wheel 200 and the mounting seat 600. Thus, the rotating wheel 200 and the mounting seat 600 can be prevented from freely moving relative to each other in a direction parallel to the rotation axis L.

[0069] Of course, in other embodiments, the limiting pin 710 may also be arranged to be inclined relative to the rotation axis L, that is, the angle between the limiting pin 710 and the rotation axis L is an acute angle.

[0070] In an embodiment, the limit pin 710 can cooperate with the travel groove 621 to limit the rotation travel of the rotating wheel 200, thereby preventing the rotating wheel 200 from excessively rotating and causing damage to the traction line 3000 and / or the mirror body 2000.

[0071] In some embodiments, the endoscope handle 1000 further includes a first limit plate 741 and a second limit plate 742. The first limit plate 741 and the second limit plate 742 are both connected to one side of the mounting seat body 610 facing the first connecting shaft 620. Along the rotation direction of the rotating wheel 200, the first limit plate 741 and the second limit plate 742 are respectively arranged on both sides of the limit pin 710, and the first limit plate 741 and the second limit plate 742 are both located on the moving path of the limit pin 710.

[0072] In some embodiments, at least one of the first limiting plate 741 and the second limiting plate 742 is detachably connected to the mounting seat body 610, and the position is adjustable in the rotation direction of the rotating wheel 200. In the embodiment, the first limiting plate 741 and the second limiting plate 742 can cooperate to limit the moving stroke of the limiting pin 710, and the length of the moving stroke can be adjusted as needed, so that the rotation stroke of the rotating wheel 200 is adapted to different mirror bodies 2000, thereby improving the versatility of the endoscope handle 1000.

[0073] In some embodiments, the first limit plate 741 and the second limit plate 742 can be detachably connected to the mounting seat body 610, and the first limit plate 741 and the second limit plate 742 can be adjusted in the rotation direction of the rotating wheel 200. Thus, the movement stroke of the limit pin 710 can be further expanded, that is, the rotation stroke of the rotating wheel 200 can be expanded to adapt to more diverse scopes 2000, and further improve the versatility of the endoscope handle 1000.

[0074] In some other embodiments, the first limiting plate 741 or the second limiting plate 742 can be detachably connected to the mounting seat body 610 .

[0075] like Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, a waist-shaped hole 7411 extending along the rotation direction of the rotating wheel 200 is provided on the first limiting plate 741. The endoscope handle 1000 further includes a locking member 720, which may include an integral connecting rod portion 721 and a limiting edge 722 located at one end of the connecting rod portion 721. A plurality of connecting holes 611 cooperating with the locking member 720 are provided on the mounting seat body 610, and the plurality of connecting holes 611 are sequentially distributed along the rotation direction of the rotating wheel 200. When the first limiting plate 741 is connected to the mounting seat body 610, the connecting rod portion 721 of the locking member 720 is sequentially penetrated through the waist-shaped hole 7411 and the connecting hole 611, and may be threadedly connected with the inner wall of the connecting hole 611. The limiting edge 722 abuts against the side of the first limiting plate 741 away from the mounting seat body 610, and presses and locks the first limiting plate 741 on the mounting seat body 610. It should be noted that the connecting rod portion 721 and the limiting edge 722 are not limited to being an integrally formed structure, and the two may also be fixedly connected by welding or other methods.

[0076] When it is necessary to adjust the position of the first limiting plate 741, the locking piece 720 can be unscrewed relative to the mounting seat body 610 to separate the limiting edge 722 from the first limiting plate 741. Thus, the position of the first limiting plate 741 can be adjusted as needed, and after the first limiting plate 741 is adjusted into place, the first limiting plate 741 can be locked and fixed to the mounting seat body 610 by the locking piece 720.

[0077] In other embodiments, the locking member 720 may also be detachably connected to the mounting seat body 610 by snap-fitting or other means.

[0078] In some embodiments, the structure and installation method of the second limiting plate 742 may be similar to the structure and installation method of the first limiting plate 741 , and will not be described in detail herein.

[0079] In other embodiments, the limit pin 710 may also be parallel to the rotation axis L of the rotating wheel 200. One end of the limit pin 710 is fixedly connected to the rotating wheel body 210. The other end of the limit pin 710 is penetrated through the mounting seat body 610 and protrudes relative to the side of the mounting seat body 610 away from the rotating wheel body 210. Accordingly, the travel groove 621 may be opened on the mounting seat body 610.

[0080] In some other embodiments, the first limiting plate 741 and the second limiting plate 742 may also be connected to the circumferential side of the first connecting shaft 620 and are respectively disposed at both ends of the travel groove 621 .

[0081] like Figure 2 , Figure 3 , Figures 5 to 7 As shown, in some embodiments, the self-locking mechanism 400 further includes a cylinder assembly 430. The cylinder assembly 430 is fixedly installed in the assembly cavity 101. The cylinder assembly 430 may include a cylinder 431 and a cover plate 432. The cover plate 432 may be fixedly connected to one end of the cylinder 431 facing the second housing 120 by screw connection, snap connection or welding, and the cover plate 432 may cooperate with the cylinder 431 to enclose a closed piston cavity 4301.

[0082] Of course, in other embodiments, the piston chamber 4301 may be opened in the cylinder body 431 , and the piston chamber 4301 may be independently surrounded by the cylinder body 431 .

[0083] In some embodiments, the cover plate 432 can be fixedly connected to the mounting seat body 610 by screw connection or the like, so that the cylinder assembly 430 can be fixedly installed in the housing assembly 100 .

[0084] In some embodiments, the cylinder body 431 may be a substantially flat U-shaped structure, and accordingly, the cylinder body 431 has a flat U-shaped groove 4311, and the opening of the U-shaped groove 4311 faces one side of the wheel body 210. In the embodiment, one end of the wheel body 210 is inserted into the U-shaped groove 4311 of the cylinder body 431.

[0085] In some embodiments, the cylinder body 431 is further provided with a first piston port 4302 and a second piston port 4303. The first piston port 4302 and the second piston port 4303 are respectively arranged on both sides of the U-shaped groove 4311, and both are connected to the U-shaped groove 4311. In addition, the first piston port 4302 and the second piston port 4303 are coaxially arranged. The axis where the first piston port 4302 and the second piston port 4303 are located is parallel to the rotation axis L of the wheel body 210.

[0086] In some embodiments, the first clamping member 421 is slidably installed in the piston cavity 4301 and is telescopically arranged relative to the first piston port 4302. Correspondingly, one end of the first clamping member 421 facing the U-shaped groove 4311 is telescopically arranged relative to the U-shaped groove 4311.

[0087] The second clamping member 422 is slidably installed in the piston cavity 4301 and is telescopically arranged relative to the second piston port 4303. Correspondingly, the second clamping member 422 is telescopically arranged relative to the U-shaped groove 4311 at one end thereof facing the U-shaped groove 4311. Accordingly, the first clamping member 421 and the second clamping member 422 are arranged on opposite sides of the wheel body 210, and the second clamping member 422 is coaxially arranged with the first clamping member 421.

[0088] In some embodiments, the first clamping member 421 and the second clamping member 422 can be made of flexible materials such as silicone or rubber. The first clamping member 421 is sealed with the inner wall of the first piston port 4302 to achieve sealing at the connection position between the first clamping member 421 and the cylinder body 431 to reduce the probability of leakage. The second clamping member 422 is sealed with the inner wall of the second piston port 4303 to reduce the probability of leakage.

[0089] In some embodiments, the drive assembly 410 includes an actuator 411, which is disposed on a side of the housing assembly 100 away from the assembly cavity 101, that is, the actuator 411 is located outside the housing assembly 100, which is convenient for the user to access and operate. During use, the user can operate the drive assembly 410 through the actuator 411.

[0090] In some embodiments, the cylinder assembly 430 is further provided with a third piston port 4304 facing the second housing 120, and the third piston port 4304 can penetrate the wall plate and the cover plate 432 at one end of the cylinder 431 facing the second housing 120. In some embodiments, the actuator 411 includes a driving handle 4111. In addition, the driving assembly 410 also includes a first adapter 412 and a second adapter 413.

[0091] In some embodiments, the first adapter 412 is rotatably mounted on the second housing 120. One end of the first adapter 412 protrudes outward relative to the side of the second housing 120 away from the assembly cavity 101, and can be fixedly connected to one end of the driving handle 4111 by means of screw connection or the like. In some embodiments, a sealing ring 510 can also be provided at the connection position between the first adapter 412 and the second housing 120 to provide a sealing effect.

[0092] In some embodiments, the second adapter 413 may be roughly in a columnar structure. One end of the second adapter 413 is slidably inserted into the end of the first adapter 412 away from the driving handle 4111. In some embodiments, the sliding direction of the second adapter 413 relative to the first adapter 412 is parallel to the rotation axis L of the wheel body 210. In addition, along the rotation direction of the wheel 200, the second adapter 413 and the first adapter 412 are limitedly matched. That is, when the operator pushes the driving handle 4111 to drive the first adapter 412 to rotate, the first adapter 412 can drive the second adapter 413 to rotate synchronously.

[0093] In some embodiments, at least one limiting protrusion 4131 is protruded from the circumferential side of the second adapter 413 near one end of the first adapter 412, and the limiting protrusion 4131 is parallel to the sliding direction of the second adapter 413 relative to the first adapter 412. Correspondingly, at least one limiting groove 4121 is provided on the inner wall of the first adapter 412 facing the second adapter 413. At least one limiting protrusion 4131 can be slidably inserted into at least one limiting groove 4121 along the sliding direction of the second adapter 413 in a one-to-one correspondence. It can be understood that the limiting protrusion 4131 fits with the inner wall of the limiting groove 4121. When the first adapter 412 rotates, the second adapter 413 can be driven to rotate synchronously under the cooperation of the limiting protrusion 4131 and the limiting groove 4121.

[0094] Of course, in other embodiments, two or three equal numbers of limiting protrusions 4131 can also be slidably inserted into the same limiting groove 4121 at the same time.

[0095] In some embodiments, the second adapter 413 is provided with a plurality of position-limiting protrusions 4131 protruding from the circumferential side near one end of the first adapter 412, for example, two, three, six or eight or any other number. The plurality of position-limiting protrusions 4131 may be evenly spaced and distributed on the circumferential side of the second adapter 413. The first adapter 412 is provided with position-limiting grooves 4121 having the same number as the position-limiting protrusions 4131. The plurality of position-limiting protrusions 4131 are slidably inserted into the plurality of position-limiting grooves 4121 in a one-to-one correspondence. When the first adapter 412 drives the second adapter 413 to rotate, it can ensure that each circumferential position of the second adapter 413 is subjected to uniform force, thereby reducing the possibility of the second adapter 413 being twisted off.

[0096] In other embodiments, the plurality of limiting protrusions 4131 may be non-uniformly distributed around the second adapter 413 .

[0097] In some other embodiments, a limiting convex portion 4131 may be protruded from the peripheral side of the second adapter 413 near one end of the first adapter 412. A limiting groove 4121 may be provided on the first adapter 412. The limiting convex portion 4131 may be slidably inserted in the limiting groove 4121.

[0098] In the embodiment, the end of the second adapter 413 away from the first adapter 412 is inserted into the third piston port 4304 and is threadedly connected with the cover plate 432. The end of the second adapter 413 close to the cylinder body 431 is slidably arranged relative to a section of the third piston port 4304 on the cylinder body 431. In addition, a sealing sleeve 520 is also sleeved on the end of the second adapter 413 close to the cylinder body 431, and the side of the sealing sleeve 520 facing away from the second adapter 413 is sealed with the inner wall of the third piston port 4304 in the upper section of the cylinder body 431, so that the connection position of the second adapter 413 and the cylinder assembly 430 can be sealed to reduce the probability of leakage.

[0099] In some embodiments, the piston chamber 4301 may be filled with hydraulic oil.

[0100] In other embodiments, the piston chamber 4301 may also be filled with gas, such as an inert gas such as nitrogen.

[0101] In some embodiments, an injection hole 4305 communicating with the piston chamber 4301 is further provided at one end of the cylinder body 431 away from the cover plate 432. Thus, hydraulic oil can be injected into the piston chamber 4301 through the injection hole 4305. In addition, the self-locking mechanism 400 further includes a sealing plug 440 and an oil seal nut 450. The sealing plug 440 is sealably inserted in the injection hole 4305 to achieve sealing of the injection hole 4305. The oil seal nut 450 is covered on the side of the sealing plug 440 away from the cylinder body 431 and is threadedly connected to one end of the cylinder body 431 close to the injection hole 4305, thereby preventing the sealing plug 440 from arbitrarily detaching from the injection hole 4305, ensuring the sealing effect of the injection hole 4305, and reducing the probability of leakage.

[0102] In the embodiment, the self-locking mechanism 400 includes an unlocking state and a locking state. When the self-locking mechanism 400 switches from the unlocking state to the locking state, the operator can push the driving handle 4111 to rotate along the first preset direction, and the driving handle 4111 drives the second adapter 413 to rotate synchronously through the first adapter 412. Since the cylinder assembly 430 is fixedly arranged relative to the housing assembly 100, under the threaded cooperation of the second adapter 413 and the cover plate 432, the second adapter 413 can slide relative to the first adapter 412, and the second adapter 413 can gradually extend into the piston cavity 4301 through the third piston port 4304. When the second adapter 413 gradually extends into the piston cavity 4301, the pressure in the piston cavity 4301 will gradually increase, and at the same time, the first clamping member 421 and the second clamping member 422 will be protruded in the direction close to the wheel body 210, so that the first clamping member 421 and the second clamping member 422 are close to each other and gradually clamp the wheel body 210. When the driving handle 4111 is rotated to the first preset position, the first clamping member 421 and the second clamping member 422 can cooperate to clamp the rotating wheel body 210 , so that the rotating wheel 200 remains fixed relative to the housing assembly 100 .

[0103] When the self-locking mechanism 400 is in the locked state, the rotating wheel 200 is completely clamped and fixed by the first clamping member 421 and the second clamping member 422, which can prevent the rotating wheel 200 from being unlocked at will and causing the bending direction and / or angle of the mirror body 2000 to change, thereby ensuring the smooth progress of the operation.

[0104] When the self-locking mechanism 400 switches from the locked state to the unlocked state, the operator can push the driving handle 4111 to rotate along the second preset direction, and the driving handle 4111 drives the second adapter 413 to rotate synchronously through the first adapter 412. The second preset direction is opposite to the first preset direction. Since the cylinder assembly 430 is fixed relative to the housing assembly 100, the second adapter 413 can slide relative to the first adapter 412 under the threaded cooperation of the second adapter 413 and the cover plate 432, and the second adapter 413 can be pulled out of the piston chamber 4301 through the third piston port 4304. When the second adapter 413 is pulled out relative to the piston chamber 4301, the pressure in the piston chamber 4301 will gradually decrease. Under the action of atmospheric pressure, the first clamping member 421 and the second clamping member 422 can be pushed to move away from the rotating wheel body 210 at the same time, so that the first clamping member 421 and the second clamping member 422 are separated from each other and gradually release the rotating wheel body 210. When the driving handle 4111 is rotated to the second preset position, the first clamping member 421 and the second clamping member 422 can completely release the rotating wheel body 210, and the rotating wheel 200 can rotate smoothly relative to the housing assembly 100. When the operator adjusts the bending of the mirror body 2000, only a small force is required to push the push handle 300, so as to make a larger adjustment, which can also improve the convenience of the operator's operation and reduce errors in the human operation process.

[0105] When fine adjustment of the mirror body 2000 is required, the driving handle 4111 can be rotated along the first preset direction so that the first clamping member 421 and the second clamping member 422 contact the rotating wheel body 210 and apply a certain friction resistance to the rotating wheel body 210, thereby increasing the resistance of the operator to rotate the push handle 300, so that the operator can perform more fine adjustments and improve the adjustment accuracy of the mirror body 2000.

[0106] like Figure 2 , Figure 3 and Figure 8As shown, in other embodiments, the actuator 411 may include a button group 4112, and the button group 4112 is arranged on the side of the housing assembly 100 away from the assembly cavity 101. The drive assembly 410 also includes a pump body 414. Among them, the pump body 414 can be an oil pump or an air pump. The output end of the pump body 414 is connected to the piston cavity 4301 through a pipeline. The button group 4112 is electrically connected to the pump body 414. In the embodiment, the button group 4112 includes a first button 41121 and a second button 41122, wherein the first button 41121 is used for the operator to input a command to control the self-locking mechanism 400 to switch from a locked state to an unlocked state, and the second button 41122 is used for the operator to input a command to control the self-locking mechanism 400 to switch from an unlocked state to a locked state. When the self-locking mechanism 400 is switched from the locked state to the unlocked state, the operator can press the first button 41121, and the pump body 414 gradually extracts the hydraulic oil (or gas) in the piston chamber 4301 after receiving the command, so that the pressure in the piston chamber 4301 gradually decreases, and under the action of atmospheric pressure, the first clamping member 421 and the second clamping member 422 move in the direction away from the wheel body 210 to gradually release the wheel body 210, so as to achieve the unlocking of the wheel body 210. When the self-locking mechanism 400 is switched from the unlocked state to the locked state, the operator can press the second button 41122, and the pump body 414 gradually injects hydraulic oil (or gas) into the piston chamber 4301 after receiving the command, so that the pressure in the piston chamber 4301 gradually increases, and under the action of the pressure difference, the first clamping member 421 and the second clamping member 422 can move in the direction close to the wheel body 210 to gradually clamp the wheel body 210, so as to achieve the locking of the wheel body 210. In this embodiment, the state switching of the self-locking mechanism 400 is controlled by the button group 4112 and the pump body 414. On the one hand, the difficulty of operation can be reduced, and it is convenient for the operator to operate with one hand. On the other hand, the setting of related structures such as the driving handle 4111 can be eliminated, and the structure connecting the inside and outside of the housing assembly 100 can be reduced, so that the endoscope handle 1000 has higher sealing performance, the probability of leakage problems can be reduced, and better dust and water protection can be provided for the internal structure of the housing assembly 100, thereby extending the service life of the endoscope handle 1000.

[0107] In other embodiments, the button group 4112 may also include a button for an operator to input instructions for controlling the self-locking mechanism 400 to switch states.

[0108] like Fig. 9As shown, an embodiment further provides an endoscope system, comprising a scope body 2000, a traction line 3000, and an endoscope handle 1000 provided in the embodiment. One end of the scope body 2000 is connected to the endoscope handle 1000. One end of the traction line 3000 is fixedly connected to an end of the scope body 2000 away from the endoscope handle 1000, and the other end of the traction line 3000 is wound around the circumference of the rotating wheel body 210 and fixedly connected to the rotating wheel body 210. Among them, the end of the scope body 2000 away from the endoscope handle 1000 is bendable.
