[0052] like Figure 1 As shown, an endoscope handle 1000 is provided in the embodiment, which can be applied in an endoscope system and can be used to lock the pull wire in the endoscope system and then lock the bending of the endoscope body.

[0053] like Figures 1 to 3 As shown, in some embodiments, the endoscope handle 1000 includes a housing assembly 100 , a rotating wheel 200 , a handle 300 , and a self-locking member 400 .

[0054] The interior of the housing assembly 100 is a hollow structure and is provided with a receiving cavity 101. The handle 300 is rotatably mounted on a side of the housing assembly 100 away from the receiving cavity 101, that is, the handle 300 is rotatably mounted on the outside of the housing assembly 100 for operation by the user.

[0055] The rotating wheel 200 is disposed in the accommodating cavity 101 of the housing assembly 100 and is rotatably connected to the housing assembly 100. In addition, the rotating wheel 200 includes a connecting shaft 220. The connecting shaft 220 can be passed through the housing assembly 100 and is transmission-connected to the handle 300. When the operator rotates the handle 300, the rotating wheel 200 can be driven to rotate synchronously.

[0056] In some embodiments, at least two clamping jaws 111 are configured on a side of the housing assembly 100 facing the handle 300 , and the at least two clamping jaws 111 are disposed on the peripheral side of the connecting shaft 220 , and the at least two clamping jaws 111 are coaxially disposed with the connecting shaft 220 .

[0057] The self-locking member 400 is disposed on the circumference of at least two clamping jaws 111. In the embodiment, the self-locking member 400 has a self-locking state 402 and an unlocking state 401.

[0058] like Figures 1 to 3 as well as Figure 4 , Figure 6 When the self-locking member 400 is in the self-locking state 402, the self-locking member 400 can squeeze at least two clamping jaws 111, and make at least two clamping jaws 111 clamp the connecting shaft 220. Thus, the rotating wheel 200 can be kept fixed relative to the housing assembly 100, that is, the self-locking of the rotating wheel 200 is achieved, and the self-locking function of the endoscope handle 1000 is achieved.

[0059] When the self-locking member 400 is in the unlocking state 401, the self-locking member 400 can release at least two clamping jaws 111, and at least two clamping jaws 111 release the connecting shaft 220. Thus, the rotating wheel 200 can smoothly rotate relative to the housing assembly 100 to achieve the unlocking effect, so as to adjust the curvature of the mirror body.

[0060] In the embodiment of the present application, at least two clamping jaws 111 are coaxially arranged with the connecting shaft 220 of the rotating wheel 200. When locking the rotating wheel 200, the force applied by at least two clamping jaws 111 to the rotating wheel 200 can be distributed at different positions around the rotating wheel 200, so that the force on the rotating wheel 200 can be more balanced, the self-locking effect can be improved, and the operator can also obtain a better operating feel.

[0061] like Figures 1 to 3As shown, in some embodiments, 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 the first housing 110 and the second housing 120 are fixedly connected or detachably fixedly connected. The fixed connection may be, for example, welding or bonding, and the detachable fixed connection may be, for example, connected by screw connection or snap connection. In the embodiment, the first housing 110 and the second housing 120 may cooperate to enclose the accommodating cavity 101.

[0062] like Figures 1 to 3 As shown, in some embodiments, the wheel 200 further includes a wheel body 210. A connecting shaft 220 is disposed through the wheel body 210, and the connecting shaft 220 can be coaxially disposed with the wheel body 210. In some embodiments, the wheel body 210 and the connecting shaft 220 can be an integral structure.

[0063] In some embodiments, the rotating wheel body 210 may be disposed in the accommodating cavity 101 of the housing assembly 100 and may be rotatably disposed relative to the housing assembly 100. A pull line for pulling the mirror body to bend may be wound around the rotating wheel body 210. The connecting shaft 220 may be passed through the first housing 110 and protrude and be exposed relative to a side of the first housing 110 away from the second housing 120.

[0064] In some embodiments, the handle 300 may include a connected handle body 310 and a connecting sleeve 320. The connection between the handle body 310 and the connecting sleeve 320 may be an integral molding or a detachable fixed connection. Among them, the handle body 310 may be roughly L-shaped. Accordingly, the handle body 310 may include a first structural segment 311 and a second structural segment 312 connected to each other, and the first structural segment 311 is roughly perpendicular to the second structural segment 312. In the embodiment, the first structural segment 311 is spaced apart on the side of the first shell 110 away from the second shell 120. The second structural segment 312 extends in the direction of the first structural segment 311 close to the connecting shaft 220, and is spaced apart on one side of the shell assembly 100.

[0065] The connecting sleeve 320 may protrude from the first structural section 311 toward the first housing 110 . The connecting sleeve 320 may be sleeved on the end of the connecting shaft 220 protruding relative to the first housing 110 , and limitedly abut against the side of the first housing 110 away from the second housing 120 .

[0066] In the embodiment, the connecting sleeve 320 may be non-circularly matched with the connecting shaft 220. Specifically, the cross section of the connecting shaft 220 protruding from the first shell 110 may be non-circular, wherein the cross section may be perpendicular to the axial direction of the connecting shaft 220. The connecting sleeve 320 is provided with a connecting groove 321, and the connecting groove 321 is located on the side of the connecting sleeve 320 facing the first shell 110. The cross section of the connecting groove 321 perpendicular to the axial direction of the connecting shaft 220 may also be non-circular, and is consistent with the cross section of the connecting shaft 220 protruding from the first shell 110. Thus, the connecting sleeve 320 and the connecting shaft 220 can be prevented from rotating relative to each other, that is, the handle 300 and the connecting shaft 220 can be prevented from rotating relative to each other, ensuring that the rotating wheel 200 can be driven to rotate synchronously when the handle 300 is operated.

[0067] In some embodiments, a screw 500 can be inserted into the connecting shaft 220 from the end of the connecting shaft 220 away from the connecting sleeve 320, and extend to the connecting sleeve 320 and be screwed with the connecting sleeve 320. The head of the screw 500 can be limitedly abutted against the end surface of the connecting shaft 220 away from the connecting sleeve 320. Thus, a fixed connection between the rotating wheel 200 and the handle 300 can be achieved.

[0068] In other embodiments, the connecting sleeve 320 and the connecting shaft 220 may be fixedly connected by bonding or riveting.

[0069] During use, the operator can turn the handle 300 to drive the rotating wheel 200 to rotate, and then the rotation of the rotating wheel 200 drives the wire to pull the mirror body to bend.

[0070] like Figures 2 to 6 As shown, in some embodiments, a side of the first housing 110 facing away from the second housing 120 may be recessed to form a sink 113, and the sink 113 may be formed by the first housing 110 being recessed in a direction close to the second housing 120. The connecting shaft 220 may pass through the sink 113, and one end of the connecting shaft 220 may protrude relative to the opening of the side of the sink 113 facing away from the second housing 120, and be connected to the connecting sleeve 320 of the handle 300. In an embodiment, the sink 113 may be coaxially arranged with the connecting shaft 220.

[0071] The clamping jaw 111 can extend from the bottom of the groove 113 in a direction away from the second housing 120 , and the clamping jaw 111 is also accommodated in the groove 113 .

[0072] In some embodiments, two clamping jaws 111 may be configured on one side of the first shell 110 facing away from the second shell 120. The two clamping jaws 111 may be arranged around the peripheral side of the connecting shaft 220 and evenly distributed, that is, the two clamping jaws 111 are arranged opposite to each other. When the self-locking member 400 is in the self-locking state 402, the self-locking member 400 may squeeze the two clamping jaws 111 and drive the two clamping jaws 111 to cooperate in clamping the connecting shaft 220. In the embodiment, the two clamping jaws 111 are symmetrically arranged, and accordingly, the force applied by the two clamping jaws 111 to the rotating wheel 200 can also be symmetrically distributed, so that the force on the peripheral side of the rotating wheel 200 is more balanced, the self-locking effect is improved, and the operator has a better operating feel.

[0073] In other embodiments, the first housing 110 may be provided with three, four, or six clamping jaws 111 on the side facing away from the second housing 120. The plurality of clamping jaws 111 may be evenly or unevenly spaced and arranged around the circumference of the connecting shaft 220. When the self-locking member 400 is in the self-locking state 402, the self-locking member 400 may squeeze the plurality of clamping jaws 111 at the same time and drive the plurality of clamping jaws 111 to cooperate and clamp the connecting shaft 220.

[0074] In some embodiments, when the two clamping jaws 111 cooperate to clamp the connecting shaft 220 , the surfaces of the two clamping jaws 111 facing the connecting shaft 220 can fit with the connecting shaft 220 , that is, the clamping jaws 111 are in surface contact with the connecting shaft 220 .

[0075] In an embodiment, the shape of the surface of the clamping jaw 111 facing the connecting shaft 220 can match the shape of the connecting shaft 220 and the relative position of the clamping jaw 111. In some embodiments, a section of the connecting shaft 220 opposite to the two clamping jaws 111 can be cylindrical. Correspondingly, the surface of the two clamping jaws 111 facing the connecting shaft 220 can be an arc surface, that is, both are part of the cylindrical surface, and can be on the same cylindrical surface. When the two clamping jaws 111 clamp the connecting shaft 220, the surface of the two clamping jaws 111 facing the connecting shaft 220 can fit the outer wall surface of the connecting shaft 220. Thereby, the contact area between the two clamping jaws 111 and the connecting shaft 220 can be increased, the resistance of the connecting shaft 220 when rotating relative to the two clamping jaws 111 can be increased, and the possibility of the self-locking member 400 being unlocked at will in the self-locking state 402 can be reduced, thereby ensuring the stability of the self-locking function of the endoscope handle 1000.

[0076] In other embodiments, the section of the connecting shaft 220 opposite to the two clamping jaws 111 may also be a polygonal columnar structure such as a quadrangular prism or a pentagonal prism. The surfaces of the two clamping jaws 111 facing the connecting shaft 220 may be part of the corresponding prism surface and are on the same prism surface.

[0077] In other embodiments, when the self-locking member 400 is in the self-locking state 402 , that is, when the two clamping jaws 111 clamp the connecting shaft 220 , there may also be line contact between the two clamping jaws 111 and the connecting shaft 220 .

[0078] like Figure 2 , Figures 4 to 7 As shown, in some embodiments, the surface of the clamping jaw 111 facing away from the connecting shaft 220 is also an arc surface. And the surfaces of the two clamping jaws 111 facing away from the connecting shaft 220 can be on the same cylindrical surface and coaxial with the connecting shaft 220.

[0079] In some embodiments, two supporting portions 112 are further configured on a side of the first shell 110 away from the second shell 120 . The two supporting portions 112 can also be arranged around the circumference of the connecting shaft 220 , and the two supporting portions 112 can be alternately arranged with the two clamping jaws 111 .

[0080] In the embodiment, the surface of the support portion 112 facing the connecting shaft 220 may be an arc surface. And the diameter of the surface of the support portion 112 facing the connecting shaft 220 may be equal to the diameter of the surfaces of the two clamping jaws 111 facing the connecting shaft 220. That is, the inner diameter of the support portion 112 is equal to the inner diameter of the clamping jaws 111, and both are equal to or slightly larger than the diameter of a section of the connecting shaft 220 opposite to the clamping jaws 111.

[0081] The surface of the support portion 112 facing away from the connecting shaft 220 may also be an arc surface and is coaxially arranged with the connecting shaft 220. In some embodiments, the diameter of the surface of the clamping jaw 111 facing away from the connecting shaft 220 (i.e., the outer diameter d of the clamping jaw 111) is 1 ), which may be larger than the diameter of the surface of the support portion 112 facing away from the connecting shaft 220 (ie, the outer diameter d of the support portion 112). 2 ). That is, the two clamping jaws 111 may protrude along the radial direction of the connecting shaft 220 relative to the side of the supporting portion 112 away from the connecting shaft 220 .

[0082] like Figures 2 to 7 As shown, in some embodiments, the self-locking member 400 may include an integrated self-locking sleeve 410 and an operating handle 420. The operating handle 420 may be connected to one side of the self-locking sleeve 410 and extend radially of the self-locking sleeve 410. Moreover, the operating handle 420 may be located at one end of the axial direction of the self-locking sleeve 410.

[0083] In the embodiment, the self-locking sleeve 410 can be inserted into the sink 113 and sleeved on the side of the two clamping jaws 111 and the two supporting parts 112 away from the connecting shaft 220. The operating handle 420 can be located on the side of the sink 113 away from the second housing 120, and between the first housing 110 and the first structural section 311 of the handle 300 in the axial direction of the connecting shaft 220. In addition, in the circumferential direction of the connecting shaft 220, the operating handle 420 and the handle 300 are staggered, so that the operator can easily touch the operating handle 420 and the handle 300 respectively to perform related operations.

[0084] In some embodiments, at least two gradually changing arc structures 411 may be configured on a side of the self-locking sleeve 410 facing the clamping jaws 111 , and the at least two gradually changing arc structures 411 may correspond to the at least two clamping jaws 111 in a one-to-one manner.

[0085] In some embodiments, two gradual arc structures 411 may be configured on one side of the self-locking sleeve 410 facing the clamping jaw 111 , wherein one gradual arc structure 411 may be disposed opposite to one of the clamping jaws 111 , and the other gradual arc structure 411 may be disposed opposite to the other clamping jaw 111 .

[0086] In an embodiment, the self-locking member 400 may be configured with a self-locking direction M. The self-locking direction M may be directed from the position of the operating handle 420 when the self-locking member 400 is in the unlocking state 401 to the position of the operating handle 420 when the self-locking member 400 is in the self-locking state 402 .

[0087] In some embodiments, the diameter of the gradually changing arc structure 411 may gradually increase along the self-locking direction M. In addition, the minimum diameter of the gradually changing arc structure 411 may be smaller than the diameter of the surface of the clamping jaw 111 facing away from the connecting shaft 220 (i.e., the outer diameter d of the clamping jaw 111). 1 ), the maximum diameter of the gradually changing arc structure 411 may be larger than the diameter of the surface of the clamping jaw 111 on the side away from the connecting shaft 220 (ie, the outer diameter d of the clamping jaw 111). 1 ).

[0088] When the self-locking member 400 rotates along the self-locking direction M, the self-locking sleeve 410 can gradually squeeze the two clamping jaws 111 and drive the two clamping jaws 111 to gradually clamp the connecting shaft 220 to clamp and fix the connecting shaft 220. When the rotating wheel 200 needs to be unlocked, the self-locking member 400 can be rotated in the opposite direction of the self-locking direction M, and the gradual arc structure 411 can be gradually separated from the relative clamping jaws 111, so that the two clamping jaws 111 can gradually release the connecting shaft 220, so that the rotating wheel 200 can rotate relative to the housing.

[0089] In the embodiment, during the process of the self-locking member 400 switching from the unlocking state 401 to the self-locking state 402, the self-locking member 400 can gradually drive the two clamping jaws 111 to clamp the connecting shaft 220, and gradually increase the clamping force applied by the two clamping jaws 111 to the connecting shaft 220. Accordingly, the operator can also adjust the clamping force applied by the two clamping jaws 111 to the connecting shaft 220, that is, the self-locking force of the endoscope handle 1000 can be adjusted as needed. Exemplarily, when it is necessary to increase the self-locking force on the connecting shaft 220, the self-locking member can be rotated in the self-locking direction M. When it is necessary to reduce the self-locking force on the connecting shaft 220, the self-locking member 400 can be rotated in the opposite direction of the self-locking direction M to reduce the force applied by the clamping jaws 111 to the connecting shaft 220.

[0090] like Figure 8 and Fig. 9 As shown, in some embodiments, the outer wall of the self-locking sleeve 410 on the side away from the clamping jaw 111 is provided with a travel groove 412. The side wall of the sink 113 opposite to the clamping jaw 111 may be protrudingly provided with a limit block 114, and the limit block 114 may be slidably disposed in the travel groove 412. Therefore, the limit block 114 and the travel groove 412 may cooperate to limit the rotational travel of the self-locking member 400, that is, limit the self-locking travel, and prevent the self-locking member 400 from rotating excessively, causing the endoscope handle 1000 to be unable to be used normally.

[0091] In other embodiments, the travel groove 412 may also be formed on the inner wall of the sink 113 facing the connecting shaft 220 , and the limit block 114 may protrude from the side of the self-locking sleeve 410 facing away from the connecting shaft 220 .

[0092] In some embodiments, the outer diameter d of the self-locking sleeve 410 is 3 It can be slightly larger than the inner diameter d of the sink 113 4 That is, the self-locking sleeve 410 may be slightly interference fit with the inner wall of the sink 113 on the side facing the clamping jaw 111. When the self-locking member 400 is rotated relative to the first housing 110, there may be a certain resistance. Thus, the self-locking member 400 can be suspended at any angle to achieve infinite adjustment of the self-locking force.

[0093] In some embodiments, the outer diameter d of the self-locking sleeve 410 is 3 The inner diameter d of the sink 113 4 The outer diameter d of the self-locking sleeve 410 is 0.01 mm to 0.05 mm larger, which ensures that the self-locking sleeve 410 can rotate relative to the first housing 110 under the action of an external force, and also enables the self-locking sleeve 410 to arbitrarily hover relative to the first housing 110. For example, in some embodiments, the outer diameter d of the self-locking sleeve 410 is 3 The inner diameter d of the comparable sink 113 40.01mm, 0.015mm, 0.018mm, 0.022mm, 0.027mm, 0.03mm, 0.035mm, 0.039mm, 0.042mm, 0.045mm, 0.048mm, 0.05mm, or any other value between 0.01mm and 0.05mm.

[0094] In other embodiments, the outer diameter d of the self-locking sleeve 410 is 3 It can also be equal to the inner diameter d of the sink 113 4 When the self-locking member 400 is in the self-locking state 402 , the self-locking member 400 can also be kept fixed by the action force between itself and the clamping jaw 111 .

[0095] like Figure 8 and Fig. 9 As shown, in some embodiments, a plurality of protrusions 413 are protruding from the bottom of the travel groove 412 opposite to the stop block 114. The surface of the protrusion 413 facing away from the connecting shaft 220 may be an arc surface. When the stop block 114 passes through the protrusion 413, an interference fit may be formed, and the self-locking member 400 may be kept in this position. At the same time, the operator's hand feeling during operation may also be enhanced.

[0096] In other embodiments, the bottom of the travel groove 412 opposite to the limit block 114 may be protruding with a plurality of protrusions 413, and the plurality of protrusions 413 may be sequentially arranged around the circumference of the connecting shaft 220. Thus, multi-level adjustment of the self-locking member 400, that is, multi-level adjustment of the self-locking force, may be achieved.

[0097] like Fig.10 As shown, in other embodiments, the bottom of the travel groove 412 opposite to the limit block 114 and the side surface of the limit block 114 facing the connecting shaft 220 may be provided with a positioning groove 1141, and the other may be provided with a positioning protrusion 414. Among them, a plurality of positioning grooves 1141 or positioning protrusions 414 located at the bottom of the travel groove 412 may be sequentially provided along the extension direction of the travel groove 412. Among them, the extension direction of the travel groove 412 may extend along the self-locking direction M.

[0098] In other embodiments, the self-locking member 400 may also be a clamp. When the rotating wheel 200 needs to be locked, the operator can tighten the bolt on the self-locking member 400 so that the self-locking member 400 drives the two clamping claws 111 to clamp the connecting shaft 220 to achieve the self-locking function.

[0099] In summary, the endoscope handle 1000 provided in the embodiment of the present application has a small number of parts, which can simplify the assembly process, reduce production costs, and improve production capacity. In addition, the circumferential force of the connecting shaft 220 can be more balanced, the self-locking effect can be improved, and the operator's operating feel can also be improved. In addition, the self-locking force can be adjusted steplessly or in multiple gears.

[0100] The embodiment further provides an endoscope system, which may include the endoscope handle 1000 provided in the embodiment.
