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

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

[0058] The housing assembly 100 has an assembly cavity 101. A 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. A push handle 300 is disposed on the side of the housing assembly 100 opposite to the assembly cavity 101 and is drively connected to the rotating wheel 200. In this embodiment, the traction line 3000 connected to the mirror body 2000 can be connected to the periphery of the rotating wheel 200.

[0059] The self-locking mechanism 400 includes a drive 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 located 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 rotating 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 drive assembly 410 is pulsatorically connected to both the first clamping member 421 and the second clamping member 422. The drive assembly 410 can be used to drive the first clamping member 421 and the second clamping member 422 to approach and move away from each other.

[0060] In this embodiment, when the first clamping member 421 and the second clamping member 422 approach each other and clamp the rotating wheel 200, the frictional resistance between the first clamping member 421, the second clamping member 422 and the rotating wheel 200 is 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 move 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 drive assembly 410, which will drive the first clamping member 421 and the second clamping member 422 to move closer to 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, thereby locking the mirror body 2000 and preventing 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 bending of the mirror body 2000, the operator can also operate the drive assembly 410 to drive the first clamping member 421 and the second clamping member 422 away from each other to release the rotating wheel 200. The operator can also rotate the rotating wheel 200 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 moved to achieve the bending adjustment of the mirror body 2000.

[0063] In this embodiment, 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 opposite sides, so that the rotating wheel 200 is subjected to force on both sides, keeping the rotating wheel 200 in balance and reducing the probability of the rotating wheel 200 tilting. This can prevent the rotating wheel 200 from acting in the opposite direction due to uneven force on the first clamping member 421 (or the second clamping member 422), the traction line 3000 and the endoscope body 2000, etc., reducing the possibility of damage to the first clamping member 421 (or the second clamping member 422), the traction line 3000 and the endoscope body 2000, and 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 disposed 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 means of screws or snap-fit ​​connections. A sealing ring 510 is also provided at the connection position between the first housing 110 and the second housing 120 to achieve sealing at the connection position, providing dust and water protection for the internal structure of the assembly cavity 101, reducing the probability of corrosion damage to the internal structure of the assembly cavity 101, and extending the service life of the endoscope handle 1000.

[0065] like Figures 1 to 4In some embodiments, the endoscope handle 1000 further comprises a mounting seat 600, which is arranged in the assembly cavity 101. The mounting seat 600 can comprise an integral mounting seat body 610 and a first connecting shaft 620. The mounting seat body 610 can be substantially in the form of a plate structure, and the mounting seat body 610 can be fixedly connected to the first shell 110 by screws. The first connecting shaft 620 is located on the side of the mounting seat body 610 facing the second shell 120. The end of the first connecting shaft 620 away from the mounting seat body 610 penetrates the second shell 120 and protrudes from the side of the second shell 120 facing away from the assembly cavity 101. In some embodiments, the end of the first connecting shaft 620 protruding relative to the second shell 120 can be screwed with a limiting nut 730, and the limiting nut 730 can abut the side of the second shell 120 facing 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 an integral structure, and they can also be detachably fixedly connected, for example, by screws.

[0066] In embodiments, the rotating wheel 200 is rotatably mounted on the mounting seat 600. In some embodiments, the rotating wheel 200 can comprise an integral rotating wheel body 210 and a second connecting shaft 220. The rotating wheel body 210 can 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 embodiments, the circumferential side of the rotating wheel body 210 can be provided with a wire slot, and the end of the traction wire 3000 away from the scope 2000 can be accommodated in the wire slot and can be fixedly connected with 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 an integral structure, and they can also be detachably fixedly connected, for example, by screws.

[0067] In some embodiments, the rotating wheel body 210 is arranged on the side of the mounting seat body 610 facing the first shell 110. The second connecting shaft 220 is located on the side of the rotating wheel body 210 facing the mounting seat 600. The second connecting shaft 220 can penetrate the mounting seat body 610 and the first connecting shaft 620 in turn, and protrude from the end of the first connecting shaft 620 facing away from the mounting seat body 610. The end of the second connecting shaft 220 away from the rotating wheel body 210 can be fixedly connected with one end of the push handle 300 by screw connection or the like. It can be understood that the rotating wheel body 210 can rotate relative to the mounting seat body 610, and the second connecting shaft 220 can rotate relative to the first connecting shaft 620.

[0068] In some embodiments, the endoscope handle 1000 further comprises a limiting pin 710. The limiting pin 710 can be perpendicular to the rotation axis L of the rotating wheel 200. One end of the limiting pin 710 is fixedly connected with the second connecting shaft 220. The other end of the limiting pin 710 can be inserted into the first connecting shaft 620 and protrude from the side of the first connecting shaft 620 which is away from the second connecting shaft 220. Correspondingly, the first connecting shaft 620 is provided with a stroke groove 621 for the limiting pin 710 to pass through. The stroke groove 621 is arranged in the rotation direction of the rotating wheel 200, and the limiting pin 710 is in sliding fit with the inner wall of the stroke groove 621. In the extension direction of the rotation axis L, the limiting pin 710 is in contact with the two side walls of the stroke groove 621 opposite to each other, so as to realize the axial limiting between the limiting pin 710 and the first connecting shaft 620, and further realize the axial limiting between the rotating wheel 200 and the mounting seat 600. Thus, the relative movement between the rotating wheel 200 and the mounting seat 600 in the direction parallel to the rotation axis L can be prevented.

[0069] Of course, in other embodiments, the limiting pin 710 can also be arranged obliquely relative to the rotation axis L, i.e., the included angle between the limiting pin 710 and the rotation axis L is an acute angle.

[0070] In embodiments, the limiting pin 710 can cooperate with the stroke groove 621 to limit the rotation stroke of the rotating wheel 200, so as to avoid the over-rotation of the rotating wheel 200 and the damage of the traction line 3000 and / or the scope 2000.

[0071] In some embodiments, the endoscope handle 1000 further comprises a first limiting plate 741 and a second limiting plate 742. The first limiting plate 741 and the second limiting plate 742 are both connected to the side of the mounting seat body 610 which is towards the first connecting shaft 620. In the rotation direction of the rotating wheel 200, the first limiting plate 741 and the second limiting plate 742 are arranged on the two sides of the limiting pin 710, and the first limiting plate 741 and the second limiting plate 742 are both located on the movement path of the limiting pin 710.

[0072] In some embodiments, at least one of the first limiting plate 741 and the second limiting plate 742 is detachably connected with the mounting seat body 610 and is positionally adjustable in the rotation direction of the rotating wheel 200. In embodiments, the first limiting plate 741 and the second limiting plate 742 can cooperate to limit the movement stroke of the limiting pin 710, and the length of the movement stroke can be adjusted as needed, so as to adapt the rotation stroke of the rotating wheel 200 to different scopes 2000 and improve the versatility of the endoscope handle 1000.

[0073] In some embodiments, both the first limiting plate 741 and the second limiting plate 742 are detachably connected to the mounting base body 610, and the positions of both the first limiting plate 741 and the second limiting plate 742 are adjustable in the rotation direction of the rotating wheel 200. This further expands the travel of the limiting pin 710, i.e., expands the rotational travel of the rotating wheel 200, to accommodate a wider variety of endoscope bodies 2000 and further enhance the versatility of the endoscope handle 1000.

[0074] In other embodiments, the first limiting plate 741 or the second limiting plate 742 is detachably connected to the mounting base body 610.

[0075] like Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, the first limiting plate 741 has an oblong hole 7411 extending along the rotation direction of the rotating wheel 200. The endoscope handle 1000 also 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. The mounting base body 610 has a plurality of connecting holes 611 that cooperate with the locking member 720, and the plurality of connecting holes 611 are arranged sequentially along the rotation direction of the rotating wheel 200. When the first limiting plate 741 is connected to the mounting base body 610, the connecting rod portion 721 of the locking member 720 passes through the oblong hole 7411 and the connecting hole 611 in sequence, and can 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 base body 610, and presses and locks the first limiting plate 741 onto the mounting base body 610. It should be noted that the connecting rod 721 and the limiting edge 722 are not limited to being a single molded structure; they can 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 member 720 can be unscrewed relative to the mounting base 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 to the correct position, the locking member 720 can be used to lock and fix the first limiting plate 741 onto the mounting base body 610.

[0077] In other embodiments, the locking member 720 may also be detachably connected to the mounting base body 610 by means of snap-fit ​​or other methods.

[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 again here.

[0079] In some embodiments, the limiting pin 710 can be parallel to the rotation axis L of the rotating wheel 200. One end of the limiting pin 710 is fixedly connected to the rotating wheel body 210. The other end of the limiting pin 710 penetrates the mounting seat body 610 and protrudes from the side of the mounting seat body 610 away from the rotating wheel body 210. Correspondingly, the stroke groove 621 can be formed on the mounting seat body 610.

[0080] In some embodiments, the first limiting plate 741 and the second limiting plate 742 can be connected to the circumferential side of the first connecting shaft 620 and arranged at two ends of the stroke groove 621.

[0081] As shown in FIG. 7, in some embodiments, the self-locking mechanism 400 further comprises a cylinder assembly 430. The cylinder assembly 430 is fixedly installed in the assembly cavity 101. The cylinder assembly 430 can comprise a cylinder 431 and a cover plate 432. The cover plate 432 is fixedly connected to one end of the cylinder 431 facing the second shell 120 by screw connection, buckle connection or welding, etc., and the cover plate 432 can cooperate with the cylinder 431 to form a closed piston cavity 4301. Figure 2 Figure 3 Figures 5 to 7 Of course, in other embodiments, the piston cavity 4301 can be formed in the cylinder 431, and the piston cavity 4301 can be formed independently by the cylinder 431.

[0082] In some embodiments, the cover plate 432 can be fixedly connected to the mounting seat body 610 by screw connection, etc., so that the cylinder assembly 430 can be fixedly installed in the shell assembly 100.

[0083] In some embodiments, the cylinder 431 can have a generally lying U-shaped structure, and correspondingly, the cylinder 431 has a lying U-shaped groove 4311, and the opening of the U-shaped groove 4311 faces the side of the rotating wheel body 210. In the embodiment, one end of the rotating wheel body 210 is inserted into the U-shaped groove 4311 of the cylinder 431.

[0084] In some embodiments, the cylinder 431 further has a first piston port 4302 and a second piston port 4303. The first piston port 4302 and the second piston port 4303 are arranged at two sides of the U-shaped groove 4311 and communicate with the U-shaped groove 4311. In addition, the first piston port 4302 and the second piston port 4303 are coaxially arranged. The axis of the first piston port 4302 and the second piston port 4303 is parallel to the rotation axis L of the rotating wheel body 210.

[0085] In some embodiments, the cylinder 431 further has a first piston port 4302 and a second piston port 4303. The first piston port 4302 and the second piston port 4303 are arranged at two sides of the U-shaped groove 4311 and communicate with the U-shaped groove 4311. In addition, the first piston port 4302 and the second piston port 4303 are coaxially arranged. The axis of the first piston port 4302 and the second piston port 4303 is parallel to the rotation axis L of the rotating wheel body 210.

[0086] ​​In some embodiments, the first clamping member 421 is slidingly installed in the piston cavity 4301 and is arranged in an extendible and retractable manner relative to the first piston port 4302. Correspondingly, the first clamping member 421 is arranged in an extendible and retractable manner relative to one end of the U-shaped groove 4311.

[0087] The second clamping member 422 is slidingly installed in the piston cavity 4301 and is arranged in an extendible and retractable manner relative to the second piston port 4303. Correspondingly, the second clamping member 422 is arranged in an extendible and retractable manner relative to one end of the U-shaped groove 4311. Accordingly, the first clamping member 421 and the second clamping member 422 are arranged on opposite sides of the runner 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 silica gel or rubber. The first clamping member 421 is sealingly fitted with the inner wall of the first piston port 4302 to achieve sealing of the connection position of the first clamping member 421 and the cylinder 431, thereby reducing the probability of liquid leakage. The second clamping member 422 is sealingly fitted with the inner wall of the second piston port 4303 to reduce the probability of liquid leakage.

[0089] In some embodiments, the driving assembly 410 includes an execution member 411 arranged on the side of the shell assembly 100 away from the assembly cavity 101, i.e., the execution member 411 is located on the outside of the shell assembly 100, which can be easily touched and operated by the user. During use, the user can operate the driving assembly 410 through the execution member 411.

[0090] In some embodiments, the cylinder assembly 430 further has a third piston port 4304 facing the second shell 120, which can penetrate the wall plate of the second shell 120 and the cover plate 432. In some embodiments, the execution member 411 includes a driving handle 4111. In addition, the driving assembly 410 further includes a first adapter 412 and a second adapter 413.

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

[0092] In some embodiments, the second adapter 413 can have a substantially cylindrical structure. One end of the second adapter 413 is slidingly inserted into the first adapter 412 away from the end of 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 reel body 210. In addition, the second adapter 413 is limitedly fitted with the first adapter 412 in the rotation direction of the reel 200. That is, when the operator pushes the driving handle 4111 to drive the first adapter 412 to rotate, the second adapter 413 can be synchronously rotated by the first adapter 412.

[0093] In some embodiments, at least one limiting protrusion 4131 is arranged on the periphery of the end of the second adapter 413 close to 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 arranged on the inner wall of the first adapter 412 facing the second adapter 413. The at least one limiting protrusion 4131 can be slidingly inserted into the at least one limiting groove 4121 in one-to-one correspondence in the sliding direction of the second adapter 413. It can be understood that the limiting protrusion 4131 is fitted with the inner wall of the limiting groove 4121. When the first adapter 412 rotates, the second adapter 413 can be synchronously rotated under the cooperation of the limiting protrusion 4131 and the limiting groove 4121.

[0094] Of course, in other embodiments, two or three limiting protrusions 4131 can be simultaneously slidingly inserted into the same limiting groove 4121.

[0095] In some embodiments, a plurality of limiting protrusions 4131, for example, two, three, six, or eight, or any other number, are arranged on the periphery of the end of the second adapter 413 close to the first adapter 412. The plurality of limiting protrusions 4131 can be uniformly distributed on the periphery of the second adapter 413. The first adapter 412 is provided with limiting grooves 4121 consistent with the number of limiting protrusions 4131. The plurality of limiting protrusions 4131 are slidingly inserted into the plurality of limiting grooves 4121 in one-to-one correspondence. When the first adapter 412 drives the second adapter 413 to rotate, it can ensure that the forces on each position of the periphery of the second adapter 413 are uniform, reducing the possibility of the second adapter 413 being twisted off.

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

[0097] In some embodiments, the second adapter 413 can also be provided with a limiting protrusion 4131 on the side close to the end of the first adapter 412. The first adapter 412 can be provided with a limiting slot 4121. The limiting protrusion 4131 can be slidably inserted into the limiting slot 4121.

[0098] In some embodiments, the second adapter 413 is inserted into the third piston port 4304 away from the first adapter 412 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 on the section of the cylinder body 431 above the third piston port 4304. In addition, the end of the second adapter 413 close to the cylinder body 431 is also sleeved with a sealing sleeve 520, and the side of the sealing sleeve 520 away from the second adapter 413 is sealingly connected with the inner wall of the section of the cylinder body 431 above the third piston port 4304, so that the connection position of the second adapter 413 and the cylinder assembly 430 can be sealed to reduce the probability of liquid leakage.

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

[0100] In some embodiments, the piston cavity 4301 can also be filled with gas, such as inert gas, for example, nitrogen.

[0101] In some embodiments, the cylinder body 431 is provided with a liquid injection hole 4305 communicating with the piston cavity 4301 at the end away from the cover plate 432. Thus, the piston cavity 4301 can be injected with hydraulic oil through the liquid injection hole 4305. In addition, the self-locking mechanism 400 further comprises a sealing plug 440 and an oil seal nut 450. The sealing plug 440 is sealingly inserted into the liquid injection hole 4305 to seal the liquid injection hole 4305. The oil seal nut 450 is sleeved on the side of the sealing plug 440 away from the cylinder body 431 and is screwed with the end of the cylinder body 431 close to the liquid injection hole 4305, so that the sealing plug 440 can be prevented from being separated from the liquid injection hole 4305 at will, the sealing effect of the liquid injection hole 4305 is ensured, and the probability of liquid leakage is reduced.

[0102] In the embodiment, the self-locking mechanism 400 comprises an unlocked state and a locked state. When the self-locking mechanism 400 is switched from the unlocked state to the locked state, the operator can push the driving handle 4111 to rotate in a 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 shell assembly 100, the second adapter 413 can slide relative to the first adapter 412 and gradually extend into the piston cavity 4301 through the third piston port 4304 under the cooperation of the threads of the second adapter 413 and the cover plate 432. When the second adapter 413 gradually extends into the piston cavity 4301, the pressure in the piston cavity 4301 gradually increases and simultaneously pushes the first clamping member 421 and the second clamping member 422 to protrude towards the rotating wheel body 210, so that the first clamping member 421 and the second clamping member 422 approach each other and gradually clamp the rotating wheel body 210. When the driving handle 4111 rotates to a first preset position, the rotating wheel body 210 can be clamped by the first clamping member 421 and the second clamping member 422, so that the rotating wheel 200 is kept fixed relative to the shell 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, so that the rotating wheel 200 cannot be unlocked at will to cause 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 is switched from the locked state to the unlocked state, the operator can push the driving handle 4111 to rotate in a 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 fixedly arranged relative to the shell assembly 100, the second adapter 413 is slid relative to the first adapter 412 under the cooperation of the threads of the second adapter 413 and the cover plate 432, and the second adapter 413 is pulled out of the piston cavity 4301 through the third piston port 4304. When the second adapter 413 is pulled out of the piston cavity 4301, the pressure in the piston cavity 4301 gradually decreases, and under the action of the atmospheric pressure, the first clamping piece 421 and the second clamping piece 422 are simultaneously pushed to move away from the rotating body 210, so that the first clamping piece 421 and the second clamping piece 422 move away from each other and gradually release the rotating body 210. When the driving handle 4111 is rotated to a second preset position, the first clamping piece 421 and the second clamping piece 422 completely release the rotating body 210, and the rotating wheel 200 can be smoothly rotated relative to the shell assembly 100. When the operator adjusts the mirror body 2000, only a small force is needed to push the push handle 300 to make a large amplitude adjustment, which improves the convenience of the operator and reduces the error in the operation process.

[0105] When fine adjustment of the mirror body 2000 is needed, the driving handle 4111 is rotated in the first preset direction, so that the first clamping piece 421 and the second clamping piece 422 contact the rotating body 210 and apply a certain frictional resistance to the rotating body 210, thereby increasing the resistance of the operator to rotate the push handle 300, so that the operator can make more fine adjustment and improve the adjustment accuracy of the mirror body 2000.

[0106] As Figure 2 , Figure 3 and Figure 8As shown, in some other embodiments, the execution member 411 can include a key group 4112, which is arranged on the side of the shell assembly 100 away from the assembly cavity 101. The drive assembly 410 further includes a pump body 414. The pump body 414 can be an oil pump or a gas pump. The output end of the pump body 414 is in communication with the piston cavity 4301 through a pipeline. The key group 4112 is electrically connected with the pump body 414. In an embodiment, the key group 4112 includes a first key 41121 and a second key 41122, wherein the first key 41121 is used for the operator to input an instruction for controlling the self-locking mechanism 400 to switch from the locked state to the unlocked state, and the second key 41122 is used for the operator to input an instruction for controlling the self-locking mechanism 400 to switch from the unlocked state to the locked state. When the self-locking mechanism 400 switches from the locked state to the unlocked state, the operator can press the first key 41121, and the pump body 414 gradually pumps out the hydraulic oil (or gas) in the piston cavity 4301 after receiving the instruction, so as to gradually reduce the pressure in the piston cavity 4301. Under the action of the atmospheric pressure, the first clamping member 421 and the second clamping member 422 move away from the rotating wheel body 210 to gradually release the rotating wheel body 210, so as to achieve the unlocking of the rotating wheel body 210. When the self-locking mechanism 400 switches from the unlocked state to the locked state, the operator can press the second key 41122, and the pump body 414 gradually injects hydraulic oil (or gas) into the piston cavity 4301 after receiving the instruction, so as to gradually increase the pressure in the piston cavity 4301. Under the action of the pressure difference, the first clamping member 421 and the second clamping member 422 move towards the rotating wheel body 210 to gradually clamp the rotating wheel body 210, so as to achieve the locking of the rotating wheel body 210. In this embodiment, the state switching of the self-locking mechanism 400 is controlled by the key group 4112 and the pump body 414, which can reduce the operation difficulty and facilitate the operator to perform one-handed operation. On the other hand, the setting of the drive handle 4111 and other related structures can be avoided, the structures connected inside and outside the shell assembly 100 are reduced, the endoscope handle 1000 has higher sealing performance, the probability of liquid leakage is reduced, the dustproof and waterproof protection of the structures inside the shell assembly 100 is better, and the service life of the endoscope handle 1000 is prolonged.

[0107] In some other embodiments, the key group 4112 can also include one key, which can be used by the operator to input an instruction for controlling the self-locking mechanism 400 to switch states.

[0108] As Figure 9As shown, the endoscope system in the embodiment further comprises a mirror body 2000, a traction line 3000 and the endoscope handle 1000 provided in the embodiment. One end of the mirror body 2000 is connected to the endoscope handle 1000. One end of the traction line 3000 is fixedly connected to the end of the mirror body 2000 away from the endoscope handle 1000, and the other end of the traction line 3000 is wound around the circumferential side of the rotating wheel body 210 and fixedly connected to the rotating wheel body 210. The end of the mirror body 2000 away from the endoscope handle 1000 is bendable.
