Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an endoscope control component and an endoscope. Background Art

[0002] Endoscope is a commonly used medical device that can directly enter the natural cavity of the human body for inspection and provide doctors with sufficient diagnostic information. Traditional endoscopes have a precise structure and many tiny switches, making it difficult to disassemble the parts one by one for cleaning and disinfection. Even tiny residual microorganisms and secretions provide a possible environment for cross-infection. Disposable endoscopes are gradually used in clinical experiments and some diagnosis and treatment fields, becoming a supplement to traditional endoscopes. Disposable or single-use endoscope examinations reduce the risk of cross-contamination and hospital-acquired diseases.

[0003] During the current use of endoscopes, doctors need to manually twist the product's rotating device or turn their wrists to achieve angular rotation of the product. After the instrument is inserted into the channel tube of the endoscope, the overall rotation damping load increases, making it more difficult to rotate. After rotating to the required angle, rebound will occur, which is not conducive to positioning and affects the smooth progress of the operation. Utility Model Content

[0026] Reference Figures 1 to 4 As shown, a control assembly 100 of an endoscope and an endoscope according to a preferred embodiment of the present invention are schematically shown.

[0027] The control assembly 100 of the endoscope includes a motor 110, a transmission gear set 120, a control board 130, a power cord 140 and a mounting portion 150. The control board 130 controls the motor 110 to rotate or stop. The specific rotation includes controlling the speed and rotation direction of the motor. The motor 110 is electrically connected to the power cord 140. The transmission gear set 120 includes a first gear 121 and a second gear 122. The motor 110 includes an output end. The first gear 121 is connected to the output end of the motor 110. The second gear 122 is transmission-connected to the first gear 121. The rotation axes of the motor 110 and the transmission gear set 120 are in the same direction. The second gear 122 is nested and connected to the mounting portion 150. The second gear 122 is a hollow structure. The mounting portion 150 is a hollow structure. The second gear 122 and the mounting portion 150 form a through hole. This is beneficial for the user when using the endoscope. The operating instrument can pass through the through hole formed by the second gear 122 and the mounting portion 150. During the operation, there is no interference from the rotation of the second gear 122 and the mounting portion 150 along the central axis, and the operation is more convenient.

[0028] The rotation axes of the motor 110 and the transmission gear set 120 have the same direction, and the transmission design structure is simple. Universal motors and gears can be used without additional customization, thereby reducing costs.

[0029] Specifically, in one embodiment, the diameter of the first gear 121 is smaller than the diameter of the second gear 122. The speed difference between the gears can be used to more accurately control the rotation angle.

[0030] The second gear 122 is a hollow structure. The second gear 122 has an inner surface. The inner surface is engaged with the outer surface of one end of the mounting portion 150 .

[0031] Specifically, the mounting portion 150 includes an upper engaging portion 151, a main body 152 and a lower engaging portion 153. The inner surface of the second gear 122 is adapted to be engaged with the outer surface of the upper engaging portion 151.

[0032] In other embodiments, the second gear 122 may also be integrally formed with the mounting portion 150 .

[0033] The second gear 122 is transmission-connected to the first gear 121, and the gears of the second gear 122 and the first gear 121 may be meshed with each other. In other embodiments, the transmission gear set 120 may further include a third gear, and the second gear 122 is transmission-connected to the first gear 121 via the third gear, and the second gear 122 and the first gear 121 are respectively meshed with the third gear, and the transmission connection is achieved via the third gear. It is worth mentioning that there may be multiple third gears, and the present application is not limited thereto.

[0034] The control board 130 may be a PCB, but the present application is not limited thereto.

[0035] In other embodiments, a limiting structure 160 is included. Specifically, the limiting structure 160 may be a limiting rib 161 and a limit switch 162 that cooperate with each other.

[0036] A reduction motor is also included, and the output end of the motor 110 is connected to the first gear 121 through the reduction motor.

[0037] The transmission gear set 120 can be a spur gear. The spur gear is designed with mature technology, stable transmission and good effect.

[0038] The motor 110 cooperates with the reduction motor to facilitate accurate control of the rotation angle.

[0039] The endoscope includes a handle 200 , an insertion tube 300 , and a control component 100 .

[0040] The handle 200 includes a shell, a cavity, at least one insertion port and an instrument port.

[0041] The control assembly 100 is arranged in the cavity, the insertion tube 300 can be inserted into the cavity from the insertion port, the proximal end of the insertion tube 300 is arranged in the cavity and fixedly connected to the mounting portion 150 of the control assembly 100, the distal end of the insertion tube 300 extends outward through the insertion port, and the central axis of the insertion tube 300 coincides with the central axis of the second gear 122. This is beneficial for the user to use the endoscope, and the operating instrument can pass through the through hole formed by the second gear 122, the mounting portion 150 and the insertion tube 300. During the operation, there is no interference from the rotation of the second gear 122 and the mounting portion 150 along the central axis, and the operation is more convenient.

[0043] The endoscope may include buttons or other control software, and the buttons may include left and right buttons. The buttons control the motor 110 through electrical connection to facilitate control of the rotation direction and rotation angle.

[0044] A limit rib 161 is provided on the mounting portion 150, and a limit detection switch is provided on the inner wall of the shell. When the limit rib 161 is rotated to a certain angle, the limit detection switch will fluctuate. After the switch reaches the working stroke, it will be fed back to the PCB. The PCB will disconnect the power supply of the motor 110 and stop rotating in the original direction. It can only rotate in the opposite direction to prevent excessive rotation of the front-end pipeline.

[0045] The endoscope can be connected to a display device for use. An imaging module is disposed at the distal end of the insertion tube 300.
