The present application is described below with reference to specific embodiments in conjunction with the accompanying drawings:

the embodiment of the application provides an endoscope handle, which can fix a haulage rope when needed after being connected with the haulage rope of an endoscope, so that an endoscope active bending section driven by the haulage rope is fixed, and the endoscope active bending section is kept in the current action posture.

Specifically, the structure of the endoscope handle provided in this embodiment is shown in fig. 1 to 7, and includes a housing 100, a rotating member 200 and a toggle member 300 connected to the housing 100 based on the housing 100, and a braking member 400 fixed to the toggle member 300. The housing 100 has a cavity therein, which can protect components of the endoscope handle disposed in the cavity. The housing 100 can also be connected to an active bending section of the endoscope, and a pull cord driving the bending action of the active bending section can enter the cavity of the housing 100 from the connection of the endoscope handle and the active bending section. The housing 100 is further provided with a first via hole 110 penetrating the inside and outside of the housing 100.

The rotating member 200 is disposed in the cavity, and the rotating member 200 is rotatably connected to the housing 100 such that the rotating member 200 can rotate relative to the housing 100. The rotating member 200 can be directly or indirectly connected with a traction rope entering the cavity of the housing 100, and the traction rope is pulled by controlling the rotation number and direction of the rotating member 200, so that the bending action of the active bending section is controlled. In this embodiment, the rotating member 200 is indirectly connected to the traction rope, specifically, the traction rope is fixed to other rotatable driven members (the driven members are blocked by the housing 100 in fig. 2), the rotating member 200 drives the driven members to rotate by means of gear engagement, so as to achieve the purpose of controlling the bending motion of the active bending section, in which the rotating member 200 adopts a structure of a circular gear only in one structure of the driving manner of gear engagement, and if necessary, the rotating member 200 may also be configured as a sector gear or a rod engaged with other gears such as a worm gear or a worm. Of course, in some other alternative embodiments, the traction rope may be directly connected and fixed to the rotating member 200, so that the rotating member 200 is directly connected to the traction rope, a driven member is omitted, and the purpose of controlling the bending action of the active bending section can be achieved. In this regard, the connection mode of the rotation member 200 and the traction rope is not particularly limited in this embodiment, and the specific connection structure when the rotation member 200 and the traction rope are directly connected and the specific connection structure when the rotation member 200 and the traction rope are indirectly connected are not particularly limited.

The toggle 300 is a component that is directly manipulated by the operator of the endoscope. One end of the stirring member 300 is located in the cavity of the housing 100, and one end of the stirring member 300 located in the cavity is slidably connected with the rotating member 200, and the sliding direction of the stirring member 300 relative to the rotating member 200 is the axial direction of the first through hole 110. The other end of the toggle member 300 passes through the first through hole 110 and is located outside the cavity of the housing 100, so that an operator of the endoscope can control the toggle member 300 by holding the end of the toggle member 300. And, the toggle member 300 can rotate in the first via hole 110, so that the toggle member 300 rotates relative to the first via hole 110, and the toggle member 300 can also drive the rotating member 200 to synchronously rotate during rotation.

Specifically, the toggle member 300 has a sliding portion 310, the length of the sliding portion 310 is greater than that of the first via hole 110, and the sliding portion 310 is located in the first via hole 110. In this way, the shape and size of the toggle member 300 at other positions outside the sliding portion 310 can be made not limited by the shape and size of the first via hole 110.

The brake 400 is a main component for braking the rotary member 200, the brake 400 is fixed on the toggle member 300, and the brake 400 is located outside the first via hole 110. When the toggle member 300 is driven to slide relative to the first through hole 110, the brake member 400 also slides relative to the first through hole 110, and since the first through hole 110 is disposed on the housing 100, the brake member 400 is connected to or separated from the housing 100 according to the sliding direction of the brake member 400 during the sliding process. Specifically, after the brake member 400 moves a certain distance towards the housing 100 where the first via hole 110 is located, the brake member 400 is fixedly connected with the housing 100, and at this time, the brake member 400 is relatively fixed with the housing 100, so that the toggle member 300 and the rotating member 200 that rotates synchronously with the toggle member 300 are also relatively fixed with the housing 100, thereby realizing braking of the rotating member 200; when the brake member 400 moves away from the housing 100 where the first via hole 110 is located by a certain distance, the brake member 400 is separated from the housing 100 by a certain distance, and at this time, the brake member 400 and the housing 100 are released from being relatively fixed, and the toggle member 300 can rotate and drive the rotating member 200 to synchronously rotate, so as to release the brake of the rotating member 200.

In this embodiment, the operator controls the toggle member 300 to slide along the first through hole 110, so that the brake member 400 is connected with the housing 100 and then brakes the rotating member 200, thereby maintaining the bending action of the active bending section driven by the traction rope. In addition, the brake member 400 is connected with the housing 100 to brake the rotating member 200 and the active bending section, so that an operator does not need to hold the rotating member and the active bending section, the operation strength of medical staff can be reduced, and the effect of stably maintaining the action posture of the active bending section for a longer time can be achieved.

Further, as shown in fig. 4, in the present embodiment, the outer wall of the striking member 300 is provided with a damping layer 320 having a certain length, and the damping layer 320 covers the sliding portion 310 of the striking member 300, and when the striking member 300 is assembled on the endoscope handle, a part of the damping layer 320 is located in the first through hole 110. The damping layer 320 has a compressible elasticity, and the thickness of the damping layer 320 is greater than the gap between the outer wall of the stirring member 300 and the inner wall of the first via hole 110, so that the damping layer 320 and the first via hole 110 can at least achieve an interference fit, the portion of the damping layer 320 located in the first via hole 110 can be compressed and generate an elastic force, and when no external force is applied to the stirring member 300, a friction force can be generated by the elastic force of the damping layer 320 to keep the stirring member 300 and the housing 100 where the first via hole 110 is located relatively fixed. When the driving force applied by the operator to the toggle member 300 is greater than the elastic force generated by the compression of the damping layer 320, the toggle member 300 can be driven to move.

Of course, in some alternative embodiments, the damping layer 320 may be directly disposed on the inner wall of the first via hole 110, without considering the difficulty of disposing the damping layer 320, so that the damping layer 320 also functions to keep the toggle member 300 and the housing 100 where the first via hole 110 is located relatively fixed. Or, a damping layer 320 is disposed on the outer wall of the stirring member 300 and the inner wall of the first via hole 110, and the stirring member 300 and the housing 100 where the first via hole 110 is located are relatively fixed by friction between the damping layer 320 and the damping layer 320.

Further, in the present embodiment, the toggle member 300 is provided with a first limiting portion 330 and a second limiting portion 420 disposed at intervals, and after the toggle member 300 is assembled to the endoscope handle, the first via hole 110 is located between the first limiting portion 330 and the second limiting portion 420, that is, the housing 100 where the first via hole 110 is located between the first limiting portion 330 and the second limiting portion 420. The first limiting portion 330 and the second limiting portion 420 are both protruded on the surface of the stirring member 300, the protruding height of the first limiting portion 330 and the protruding height of the second limiting portion 420 are both larger than the gap between the brake member 400 and the first through hole 110, so that the first limiting portion 330 and the second limiting portion 420 cannot enter the first through hole 110, the sliding distance of the stirring member 300 is limited by the first limiting portion 330 and the second limiting portion 420, when the stirring member 300 slides in the direction far away from the rotating member 200, the corresponding first limiting portion 330 or the second limiting portion 420 can play a role in preventing the stirring member 300 from being separated from the rotating member 200 in the sliding process, when the stirring member 300 slides in the direction close to the rotating member 200, the corresponding first limiting portion 330 or the second limiting portion 420 can play a role in reminding an operator that the brake member 400 is completely separated from the housing 100, and at this time, the rotating member 200 can be controlled by the corresponding first limiting portion 330 or the second limiting portion 420.

In the present embodiment, the first limiting portion 330 is located outside the housing 100, and the first limiting portion 330 and the toggle member 300 are integrally formed; the second limiting portion 420 is located in the housing 100, and the second limiting portion 420 is detachably connected with the stirring piece 300, so that after the second limiting portion 420 is detached, the stirring piece 300 can pass through the first through hole 110, and the stirring piece 300 can be assembled on the endoscope handle more conveniently in the production process.

Further, the stirring member 300 is slidably connected with the rotating member 200, and the stirring member 300 can drive the rotating member 200 to rotate synchronously, which is achieved by the following structure in this embodiment.

Specifically, in the present embodiment, the end of the striking member 300 is provided with a protruding prism 340, the center line of the prism 340 is coaxial with the axis of the striking member 300, and a prism groove 210 adapted to the prism 340 is provided in the axial direction of the rotating member 200, and the center line of the prism groove 210 is coaxial with the axis of the rotating member 200. The prism 340 is slidable in the prism slot 210 to enable sliding of the toggle 300 relative to the rotator 200. Preferably, the prism 340 is in clearance fit with the prism slot 210, so that the sliding between the prism 340 and the prism slot 210 is satisfied, and the prism 340 can drive the rotating member 200 with the prism slot 210 to synchronously rotate during the rotation process. The prism 340 may be a triangular prism 340, or may be a triangular prism 340 or other prisms 340 with a larger number of side edges, and in this embodiment, the number of side edges of the prism 340 is not particularly limited.

It should be noted that in some other alternative embodiments, the positions of the prisms 340 and the prism slots 210 may be interchanged, that is: the prism 340 is disposed on the rotation member 200, and the prism slot 210 is disposed on the striking member 300. This arrangement also enables the sliding movement of the toggle member 300 and the rotary member 200 to be performed in synchronization with each other. Thus, the method is applicable to a variety of applications. The prism 340 and the prism groove 210 may be provided in a manner that one of the rotating member 200 and the braking member 400 is provided with the prism groove 210, and the other of the rotating member 200 and the braking member 400 is provided with the prism 340.

Additionally, in some alternative embodiments, splines may be used instead of prisms 340 and spline grooves may be used instead of prism grooves 210, allowing sliding of the splines in the spline grooves.

Further, the rotation member 200 is rotated on the housing 100 by the cooperation of the rotation shaft 220 and the rotation shaft hole 120. Specifically, in the present embodiment, the rotating member 200 is provided with a rotating shaft 220, the housing 100 is provided with a rotating shaft hole 120 adapted to the rotating shaft 220, and the rotating shaft 220 is inserted into the rotating shaft hole 120, so that the rotating member 200 can rotate with the rotating shaft 220 as a rotation center, and an axial direction of the rotating member 200 is an axial direction of the rotating shaft 220.

It should be noted that, in some other alternative embodiments, the positions of the rotating shaft 220 and the rotating hole may be exchanged, that is: the rotation shaft 220 is provided on the housing 100, and the rotation shaft hole 120 is provided on the rotation member 200. This arrangement also does not interfere with the cooperation of the spindle 220 and the rotation hole and the resulting function.

Further, a protruding clamping ring 221 is circumferentially disposed on the outer wall of the rotating shaft 220 provided in the present embodiment, and a recessed clamping groove 121 is circumferentially disposed on the inner wall of the rotating shaft hole 120, where the clamping groove 121 is adapted to the clamping ring 221. When the rotation shaft 220 is connected to the rotation shaft hole 120, the clamping ring 221 is clamped in the clamping groove 121, thereby preventing the rotation member 200 from being separated from the housing 100 and the rotation member 200 from moving synchronously with the brake member 400 to some extent.

It should be noted that, in some other alternative embodiments, the positions of the clamping groove 121 and the clamping ring 221 may be interchanged, without considering the manufacturing cost, that is: the catching groove 121 is provided in the outer wall circumferential direction of the rotation shaft 220, and the catching ring 221 is provided in the inner wall circumferential direction of the rotation shaft hole 120.

Further, the brake 400 may be connected to the housing 100 by a snap fit or an abutment. In this embodiment, the brake member 400 is connected to the housing 100 in a clamping manner and brakes the rotating member 200. Specifically, a first latch 410 is disposed on the brake 400, and a second latch (the second latch is hidden by the housing 100 in fig. 4 and is not shown) adapted to the first latch 410 is disposed on the housing 100, so that the brake 400 is connected to the housing 100 in a clamping manner by engaging the first latch 410 with the second latch.

It should be noted that, in this embodiment, the first latch 410 and the second latch are face gears, and the first latch 410 and the rotating member 200 are coaxially disposed, so that when the brake member 400 rotates to any angle by using the latches radially distributed with the face gears centered on the central axis, the first latch can be quickly engaged with the second latch on the housing 100 to limit the rotation of the brake member 400.

Preferably, the first latch 410 and the second latch adopt conical gears in the face gears, so that the first latch 410 and the second latch have centripetal action in the meshing process, so that the first latch 410431 and the second latch are more stable after being meshed, and the first latch 410 and the second latch are not easy to separate due to shaking.

It should be noted that in some alternative embodiments, the brake 400 may be connected to the housing 100 in an abutting connection. And the braking member 400 is abutted against the housing 100 and generates mutual extrusion force with the housing 100, and the extrusion force is utilized to increase the friction force between the housing 100 and the braking member 400, so that the braking member 400 cannot rotate relative to the housing 100, and the purpose of braking the rotating member 200 is achieved. If necessary, a layer of a structure or material capable of increasing friction, such as rubber, may be provided at the portion where the housing 100 is connected to the brake 400 and/or at the portion where the brake 400 is connected to the housing 100. Alternatively, the friction force at the time of abutting connection is increased by increasing the roughness of the housing 100 and/or the brake 400, or a pair of magnets capable of attracting each other, preferably flexible magnets, are provided on the housing 100 and the brake 400. In addition, since the damping layer 320 provided on the striking member 300 can fix the axial sliding of the striking member 300, the braking member 400 and the housing 100 can be more easily brought into abutting connection with each other by the cooperation of the damping layer 320.

In this embodiment, the brake member 400 is fixedly connected to the toggle member 300 through the locking member 500, so that the brake member 400 can be separated from the toggle member 300 through the locking member 500 when needed. Specifically, the locking member 500 is a screw, and a second through hole is provided on the brake member 400, the second through hole can be used for the threaded end of the screw to pass through, a threaded hole is provided on the position, opposite to the second through hole, of the toggle member 300, the threaded hole is matched with the screw, and the threaded end of the screw is in threaded connection with the threaded hole, so that the locking member 500 is fixedly connected with the brake member 400 and the toggle member 300.

In some alternative embodiments, locking member 500 may also be a pin and fixedly couple brake member 400 and toggle member 300 via a pin connection. Or a separable buckle is adopted as the locking piece 500, and the clamping piece and the buckling piece in the buckle are respectively arranged on the braking piece 400 and the stirring piece 300, so that the locking piece 500 can realize the fixed connection of the braking piece 400 and the stirring piece 300.

Further, in the present embodiment, since the brake member 400 is fixedly connected to the toggle member 300 through the locking member 500, the second limiting portion 420 is disposed on the brake member 400 as a part of the brake member 400 in the present embodiment, so that the manufacturing process of the endoscope handle can be simplified. In some other alternative embodiments, the second limiting portion 420 may also be separately provided on the toggle member 300.

In addition, in this embodiment, the extending arm 350 is disposed on the stirring member 300, so that the medical staff can use the lever principle to save more effort when driving the stirring member 300 to rotate through the extending arm 350 than when directly driving the stirring member 300 to rotate. At the same time, the free end of the extension arm 350 is positioned at the rear end of the endoscope handle, such that the extension arm 350 assumes a bent shape. The bent extension arm 350 can facilitate the operator to push the toggle member 300 to slide.

Further, the embodiment also provides an endoscope, and the structure of the endoscope comprises the endoscope handle. In addition, the endoscope in the embodiment of the present application may be a bronchoscope, a pyeloscope, an esophagoscope, a gastroscope, a enteroscope, an otoscope, a rhinoscope, a stomatoscope, a laryngoscope, a colposcope, a laparoscope, an arthroscope, or the like, and the embodiment of the present application does not specifically limit the type of the endoscope.
