The endoscope handle and the endoscope provided by the embodiment of the present application will be described in detail with reference to fig. 1 to 11 through specific embodiments and application scenarios thereof.

Referring to fig. 1, the present application provides an endoscope handle, which includes a reusable section and a disposable section, wherein the reusable section and the disposable section are detachably connected, in the present application, the disposable section and the reusable section can be detachably connected by means of a threaded connector, a snap connection, a magnetic connection, and the like, and the present application does not limit the specific connection manner of the disposable section and the reusable section.

Referring to fig. 1 and 2, the reusable stage includes a first housing 100, a driving mechanism 200, an abutting piece 300 and an elastic restoring piece 400, the first housing 100 is a basic component of the reusable stage and can provide a mounting basis for the driving mechanism 200, the abutting piece 300 and the elastic restoring piece 400, that is, the driving mechanism 200, the abutting piece 300 and the elastic restoring piece 400 are all disposed on the first housing 100.

The driving mechanism 200 is connected to the docking piece 300, the driving mechanism 200 drives the docking piece 300 to rotate, the elastic reset piece 400 is connected to the driving mechanism 200, and the elastic reset piece 400 drives the driving mechanism 200 to reset, so that the docking piece 300 rotates to a docking position. In the embodiment of the present application, the driving mechanism 200 includes a driving member 210 and a transmission mechanism 220, the driving member 210 is connected to the docking member 300 through the transmission mechanism 220, the driving member 210 is operated to rotate, and the driving member 210 can drive the docking member 300 to rotate.

Referring to fig. 5 and 6, the disposable segment includes a second housing 600, a driven mechanism 700, and a locking member 900, the driven mechanism 700 and the locking member 900 are both disposed in the second housing 600, and the second housing 600 is a base member of the disposable segment and can provide a mounting base for the driven mechanism 700 and the locking member 900, that is, the driven mechanism 700 and the locking member 900 are both disposed in the second housing 600.

The driven mechanism 700 has a power input end, the power input end is rotatably disposed on the second housing 600, the power input end is used for being connected with the aforementioned abutting piece 300 to transmit torque to drive the driven mechanism 700 to move, the pulling rope 800 connected with the active bending section of the endoscope is connected with the driven mechanism 700, and under the condition that the driven mechanism 700 moves, the pulling rope 800 pulls the active bending section of the endoscope to bend.

In the embodiment of the present application, the locking member 900 is detachably connected to the follower 700, and when the locking member 900 is connected to the follower 700, the follower 700 is locked by the locking member 900, and the power input end cannot rotate around its axis, so that the power input end is in a certain butt-joint state with respect to the second housing 600, and at this time, the active bending section of the endoscope connected by the pull rope 800 is in a non-bending initial state; with the locking element 900 removed from the follower 700, the locking action of the locking element 900 is released and the power input end can rotate about its axis to allow the pull-cord 800 to pull the active bending section of the endoscope to bend.

In the process of docking the reusable section and the disposable section, the active bending section of the endoscope generally needs to be adjusted to a non-bending initial state to facilitate insertion into a human body, and the inventor finds that when the last used disposable section is discarded and the reusable section is docked with the next disposable section, the driving element 210 of the reusable section is not normally at an initial position, if the reusable section is directly docked with the next disposable section, the rotational strokes of the driving element 210 in two opposite rotational directions are not the same, and the situation that the rotational stroke of the driving element 210 in one rotational direction is limited to limit the bending of the active bending section of the endoscope easily occurs, so that the endoscope cannot be normally used, and the disposable section needs to be docked for reuse, which results in waste of medical equipment and increase of use cost.

In the embodiment of the present application, the elastic reset piece 400 drives the driving mechanism 200 to reset to the initial state, and at this time, the docking piece 300 synchronously rotates to a certain docking position; the power input end of the driven mechanism 700 is in a determined butt joint state under the locking action of the locking piece 900, so that the reusable section and the disposable section are easy to butt joint, and the butt joint efficiency of the reusable section and the disposable section is improved; after the reusable section is butted with the disposable section, the bending action of the active bending section of the endoscope in a non-bending state is matched with the rotating action of the driving part 210, the steps of the two are consistent, when the driving part 210 is operated to cross the initial position, the bending direction of the active bending section of the endoscope is changed, the operation experience and the operation accuracy of an operator are improved, in addition, the rotating strokes of the driving part 210 in two opposite rotating directions are consistent, the bending amplitudes of the active bending section of the endoscope in the two directions can reach consistency, and the conditions that the bending amplitude is too small and the use requirement cannot be met due to the fact that the driving part 210 is not in the initial position in the butt joint process are avoided.

In one embodiment, referring to fig. 1 to 2, the driving member 210 may be a shift lever, the shift lever is rotatably disposed in the first housing 100, and the transmission mechanism 220 may include a first bevel gear 221, a second bevel gear 222 and an output shaft 223, which are sequentially connected in a transmission manner, wherein a rotation axis of the driving member 210 is coaxially disposed with the first bevel gear 221, a proximal end of the output shaft 223 is connected with the second bevel gear 222, and a distal end of the output shaft 223 is fixedly connected with the docking member 300, so that the docking member 300 rotates with the rotation of the driving member 210. In this embodiment, the bevel gear transmission fit mode is adopted to rotate the docking piece 300, the bending direction of the active bending section of the endoscope can be changed by changing the rotation direction of the docking piece 300, so that the active bending section of the endoscope can be bent towards two directions, that is, the mode only needs one force transmission part docking piece 300 to control the bending of the active bending section of the endoscope, an operator only needs to dock the docking piece with a driven mechanism of the disposable section, and the operation difficulty of docking the reusable section and the disposable section is reduced.

In another alternative embodiment, the driving member 210 may be a knob, and the knob is rotatably disposed on the first housing 100, and the rotation axis of the knob is coaxial or parallel to the rotation axis of the docking member 300, for example, the knob may be coaxially connected to the docking member 300 through a transmission shaft, or the knob may be connected to the docking member 300 through a spur gear mechanism, in which case, the knob is rotated to rotate the docking member 300 synchronously.

In the process of operating the driving member 210 to drive the first bevel gear 221 to rotate, the torsion spring stores elastic potential energy, so that the driving member 210 has a tendency of resetting, and after the external force applied to the driving member 210 is removed, the torsion spring can drive the driving mechanism 200 to reset.

In another alternative embodiment, the first end of the torsion spring is fixed relative to the first housing 100, and the second end of the torsion spring is connected to a shift lever, and the shift lever rotates to elastically deform the torsion spring and store elastic potential energy; therefore, in the embodiment of the present application, the elastic reset element 400 may be connected to both the driving element 210 and the transmission mechanism 220, as long as the reset of the driving mechanism 200 is achieved.
