The reusable section of the endoscope handle, and the endoscope provided by the embodiments of the present application will be described in detail below with reference to fig. 1 to 7, by way of specific embodiments and application scenarios thereof.

The first push rod 310 is movably disposed in the first housing 100, and in the embodiment of the present application, the driving mechanism 200 drives the first push rod 310 to move relative to the first housing 100. Specifically, the first push rod 310 is provided with a first toothed section, which is engaged with the first gear 220, and when the first gear 220 is driven by the driver 210 to rotate, the first push rod 310 moves relative to the first housing 100.
In the embodiment of the present application, the two first push rods 310 are symmetrically distributed on two sides of the first gear 220, and in this layout, when the first gear 220 rotates, the two first push rods 310 move synchronously and in opposite directions, so as to realize that the active bending section of the endoscope bends in a preset direction; when the first gear 220 is driven to rotate reversely, the bending direction of the active complete section of the endoscope is changed, and the change of the bending direction can be reverse bending.
The elastic member 320 connects the first housing 100 and the first push rod 310, and under the elastic action of the elastic member 320, the distal ends of the two first push rods 310 abut against each other and form an abutting portion for abutting against the proximal end of the disposable segment, and when the reusable segment abuts against the disposable segment, the two first push rods 310 are separated, and the elastic member 320 is pressed to deform.
When the driving member 210 is operated to drive the first gear 220 to rotate, the two first push rods 310 synchronously move in opposite directions, in a further technical scheme, the first push rods 310 are provided with guide grooves 312, the guide grooves 312 extend along the axial direction of the first push rods 310, the elastic member 320 is provided with guide protrusions 321, and the guide protrusions 321 are in sliding fit with the guide grooves 312; under such a configuration, the guide slot 312 has a predetermined guide track relative to the first housing 100, and the first push rod 310 moves along the extending direction of the guide slot 312, so that the characteristics of stable movement and high precision can be achieved, and the first push rod 310 can be prevented from uncontrollably moving.
In an alternative embodiment, the elastic member 320 may be a spring, the guide protrusion 321 may be a spherical protrusion disposed at an end of the elastic member 320, the guide groove 312 matches with a profile of the spherical protrusion, when the spherical protrusion is slidably engaged with the guide groove 312, at least a portion of the spherical protrusion is located in the guide groove 312, and the spherical protrusion is engaged with the arc-shaped guide groove 312, so that the assembly efficiency of the first push rod 310 and the elastic member 320 can be improved, and meanwhile, the occurrence of a jamming phenomenon can be avoided.
In another alternative embodiment, the elastic member 320 may also be an elastic cover disposed at the distal end of the first casing 100, the elastic cover may be an annular cover body, an outer circumferential portion of the elastic cover is connected to the distal end of the first casing 100, a third through hole is disposed in the middle of the elastic cover, and the distal ends of the two first push rods 310 in the abutting state pass through the third through hole; when the two first push rods 310 are butted, the far ends of the two first push rods are separated, and the elastic cover is elastically deformed; after the reusable section and the disposable section are separated, the elastic cover is deformed again, so that the distal ends of the two first push rods 310 are pressed against each other again to form a butt joint part, and the disposable section can be conveniently butted for use with the next disposable section.
In the above solution, the distal ends of the two first push rods 310 abut against each other, so that the distal end surfaces of the two first push rods 310 are relatively deflected with respect to a plane perpendicular to the axis of the first housing 100, when the reusable section and the disposable section are abutted against each other, the distal end surface of the first push rod 310 can play a guiding role, so that the abutment component in the disposable section can slide between the distal end surfaces of the two first push rods 310 and separate the two first push rods 310; however, the deflection angle of the distal end surface of the first push rod 310 is small due to the limitation of the size of the space, so that the frictional resistance to the relative movement of the reusable section and the disposable section is large during the docking, and there is a problem that the docking is inconvenient.
Therefore, in the embodiment of the present application, the distal end of the first push rod 310 is provided with a first guiding surface 311, the first guiding surface 311 is disposed obliquely with respect to the axis of the first push rod 310, and when the distal ends of the two first push rods 310 are abutted, the two first guiding surfaces 311 form an attaching mouth 330, and the attaching mouth 330 is used for abutting against the proximal end of the disposable segment; with such a configuration, when the reusable section and the disposable section are connected, the connection component of the disposable section can slide to a position between the two first push rods 310 relative to the first guide surface 311 more easily, and the friction resistance caused by the relative movement of the reusable section and the disposable section is smaller, so that the connection process is smoother.
The first guide surface 311 may be a distal end surface of the first push rod 310, however, in this case, the sectional area of the distal end portion of the first push rod 310 is gradually reduced, and if the load is too large, the front end of the first push rod 310 is easily broken, so that the first push rod 310 cannot be always in the abutting state with the second push rod 510 after being abutted, and the stability of transmission is affected; therefore, in a further technical solution, the distal end of the first push rod 310 is provided with an abutment surface 313, the abutment surface 313 is perpendicular to the axis of the first push rod 310, the abutment surface 313 and the aforementioned first guide surface 311 together constitute a distal end surface of the first push rod 310; after the reusable section and the disposable section are butted, the two first push rods 310 can be in a parallel state, and the butting surface 313 can ensure that the first push rod 310 and the second push rod 510 have a larger contact area, so that the axial thrust can be stably transmitted, the situation that the front end surface of the first push rod 310 is completely formed by the first guide surface 311 and is easy to break is avoided, and the stability of transmission between the first push rod 310 and the second push rod 510 is improved. Of course, the aforementioned abutment surface 313 is a preferred embodiment, and it is within the scope of the present application that the first guiding surface 311 is a distal end surface of the first push rod 310.
