[0084] Through extensive and in-depth research, the inventor has disclosed for the first time a dual-motor-assisted endoscope handle assembly. Both motors have built-in sensors that need to sense the direction in which the doctor turns the knob, and then output torque on behalf of the doctor to drive the two sprockets to rotate, and then the torque is transmitted through the sprockets to pull the steel wire. This method does not require manual rotation of the knob to pull the sprocket, thereby reducing user fatigue and has important practical significance; and the two motors form two transmission chains with the knob and the sprocket respectively, and the sprocket is located between the knob and the motor. The two transmission chains do not interfere with each other, and finally drive the sprocket to rotate and pull the wire rope. Furthermore, by arranging the two motors up and down, the operating part of the handle assembly has a very compact structure.

It should be understood that these are only some examples that the present invention may take for the reader, but are not intended to limit the scope of the present invention.

[0130] Example

[0131] This embodiment provides a dual-motor-assisted endoscope handle assembly for driving a transmission chain of a sprocket component, wherein the transmission chain includes a trigger drive component, a transmission component, and an induction motor component 300. Figure 1 The figure shows the first knob 11, the second knob 13, the sprocket component and the induction motor component 300 arranged in the handle operating part 41, and the handle housing 4. The core component is located at the head of the handle housing 4 (the handle operating part 41), the induction motor component 300 is fixed to the right side of the head of the handle housing 4 by screws, the sprocket component is located in the head of the handle housing 4, and the first knob 11 and the second knob 13 are located on the left side of the handle housing 4.

[0132] The traditional endoscope handle only includes a knob module, a sprocket module and the handle housing itself. When in use, you need to use your right thumb to manually rotate the two knobs to drive the two sprockets in the head of the handle housing, which in turn drives the sprockets to rotate and pull the wire rope. This application adds a motor for assistance and uses a motor with a built-in sensor. Figure 2 As shown, when in use, when the two knobs are turned, the shaft connected to the knobs will be driven to rotate, and then the main shaft of the motor will be driven to rotate along the transmission component. The built-in sensor of the motor will sense this information, and then send a signal to the motor, the main shaft starts to rotate to output torque, and then drives the sprocket to rotate along the transmission component. If you want to stop the rotation, just hold the knob still, the motor main shaft will not be able to rotate, and the sensor will stop the motor after receiving the information. Similarly, if you want the sprocket to rotate in the opposite direction, just turn the knob in the opposite direction. Therefore, the dual-motor-assisted endoscope handle assembly of this application only needs to slightly turn the knob to drive the sprocket to rotate, which can reduce the burden on doctors when using it.

[0133] like Figure 3As shown, the dual-motor-assisted endoscope handle assembly is subdivided into an outer knob (first knob) 11, a first thrust bearing 12, an inner knob (second knob) 13, a second thrust bearing 14, an outer knob connecting shaft (first knob connecting shaft) 21, an inner knob connecting shaft (second knob connecting shaft) 22 on the left, a bevel gear (first bevel gear) 23 on the left, a sprocket (first sprocket 24) 24 on the left, a sprocket (second sprocket 25) 25 on the right, a bevel gear (third bevel gear) 26 on the right, an inner knob connecting shaft (third bevel gear connecting shaft) 27 on the right, and an upper bevel gear (second bevel gear) 2 8, sleeve 29, third thrust bearing 210, second bevel gear connecting shaft 211, first fixing plate 31, first bearing 32, second bearing 33, third bearing 34, fourth gear 35, upper motor connecting shaft (first motor connecting shaft) 36, third gear 37, gasket 38, lower motor connecting shaft (second motor connecting shaft) 39, second gear 310, first gear 311, fourth bearing 312, motor fixing plate 313 (second fixing plate 313), upper motor 314 (first motor 314), lower motor 315 (second motor 315), component housing 316, handle housing 4. The two motors are fixed on the motor fixing plate 313 by screws, and the motor main shaft passes through the motor fixing plate 313 and is connected to the upper motor connecting shaft 36 and the lower motor connecting shaft 39 respectively, and the two motor connecting shafts and the motor main shaft rotate synchronously. A second gear 310 is fixed to the upper motor connecting shaft 36 by screws, and rotates synchronously with the motor connecting shaft 36. A fourth gear 35 is fixed to the lower motor connecting shaft 39 by screws, and rotates synchronously with the motor connecting shaft 39. The first gear 311 is fixed to the outer knob connecting shaft 21 by screws, and rotates synchronously. The third gear 37 is fixed to the third bevel gear connecting shaft 27 on the right by screws, and rotates synchronously. Figure 4As shown, the second gear 310 is meshed with the first gear 311, and the third gear 37 is meshed with the fourth gear 35, so the second gear 310 is synchronously driven with the first gear 311, and the third gear 37 is synchronously driven with the fourth gear 35. The right end of the outer knob connecting shaft 21 is connected to the fourth bearing 312 on the first fixing plate 313, and the left end is fixed to the outer knob 11 by screws. The inner diameter of the third bevel gear connecting shaft 27 is larger than the outer diameter of the outer knob connecting shaft 21, so the third bevel gear connecting shaft 27 is sleeved on the outside of the outer knob connecting shaft 21, and there will be no interference when the two shafts rotate. The left end of the third bevel gear connecting shaft 27 is fixed to the third bevel gear 26 and the second sprocket 25 on the right side by screws in sequence, and rotates synchronously. The third bevel gear 26 on the right, the first bevel gear 23 on the left and the second bevel gear 28 on the top form a bevel gear transmission structure. The second bevel gear 28 is fixed to the upper bevel gear connecting shaft 211 (second bevel gear connecting shaft 211) by screws and rotates synchronously. The second bevel gear connecting shaft 211 passes through the round hole on the top of the handle housing 4 head and hangs upside down on the top of the handle housing 4 head. The third thrust bearing 210 is placed in the middle to reduce friction. The first bevel gear 23 is fixed to the right end of the inner knob connecting shaft 22 on the left by screws in sequence and rotates synchronously. Therefore, the inner knob connecting shaft 27 on the right rotates synchronously with the inner knob connecting shaft 22 on the left through this bevel gear transmission structure. The left end of the inner knob connecting shaft 22 is fixed to the inner knob 13 by screws and rotates synchronously. There is a first thrust bearing 12 between the outer knob 11 and the inner knob 13 to reduce friction, and there is a second thrust bearing 14 between the inner knob 13 and the handle housing 4 head to reduce friction.

[0134] like Figure 5 As shown, this is a transmission chain composed of the outer knob 11 and the upper motor 314, and all the components here rotate synchronously. The upper motor connecting shaft 36 and the outer knob connecting shaft 21 are two transmission shafts, and the two shafts are transmitted through the second gear 310 and the first gear 311. When in use, slightly turn the outer knob 11, and the built-in sensor of the upper motor 314 can obtain information, and then control the motor output torque to make the left first sprocket 24 rotate to the left, pulling the wire rope. If you want to stop rotating or reverse rotation, just press the outer knob 11 to keep it still or reverse rotation.

[0135] like Figure 6As shown, this is a transmission chain composed of the inner knob 13 and the lower motor 315, and all the components here rotate synchronously. The inner knob connecting shaft 22 on the left, the third bevel gear connecting shaft 27 on the right and the lower motor 39 connecting shaft are transmission shafts. The inner knob connecting shaft 22 and the third bevel gear connecting shaft 27 are driven by the first bevel gear 23 on the left, the third bevel gear 26 on the right and the second bevel gear 28 on the top, and the second bevel gear 28 is fixed on the upper bevel gear connecting shaft (second bevel gear connecting shaft) 211. The third bevel gear connecting shaft 27 and the lower motor connecting shaft 39 are driven by the third gear 37 and the fourth gear 35. When in use, slightly turn the inner knob 13, the built-in sensor of the lower motor 315 can obtain information, and then control the motor output torque, so that the second sprocket 25 on the right rotates and pulls the wire rope. If you want to stop rotating or reverse rotation, just press the inner knob 13 to keep it still or reverse rotation.
