Technical Field

[0001] The utility model relates to the technical field of medical devices, and further relates to an endoscope. Background Art

[0002] An endoscope is a commonly used medical device. It can directly enter the natural body cavity for examination, providing sufficient diagnostic information for doctors, and is increasingly widely used in diagnostic examinations, minimally invasive surgeries, etc. During the surgical operation, the doctor needs to constantly adjust the turning direction and angle of the snake bone to complete the all-round observation of the cavity and the delivery of the instrument. Manually adjusting the bending and resetting of the snake bone is cumbersome, increasing the doctor's workload, and is very laborious and inconvenient. If the snake bone is not reset to zero and is forcibly pulled out from the patient's body, it will cause harm to the patient by the instrument. Summary of the Utility Model

[0024] Refer to the attached Figures 1 to 4 As shown, a snake bone adjustment mechanism and an endoscope according to a preferred embodiment of the present utility model are schematically shown.

[0025] An endoscope designed by the present utility model includes a handle 10, an insertion part 20, and a snake bone adjustment mechanism 30. Among them, the insertion part 20 includes a snake bone 21, the snake bone adjustment mechanism 30 includes a wire fixing ring 31, a motor assembly 32, and a transmission assembly 33. At least one snake bone wire 22 is arranged inside the snake bone 21. One end of the snake bone wire 22 is fixed to the front end of the snake bone 21, and the other end passes through the insertion part 20 and is fixed to the wire fixing ring 31.

[0026] The transmission assembly 33 includes a transmission gear 331 and a driving gear 332. The transmission gear 331 is connected to the output shaft of the motor assembly 32, the driving gear 332 is fixedly connected to the wire fixing ring 31, and the transmission gear 331 is meshed and connected to the driving gear 332.

[0027] The motor assembly 32 drives the snake bone 21 to bend or reset through the transmission assembly 33 and the snake bone wire 22.

[0028] A central axis 11 is provided inside the housing of the handle 10, and the wire fixing ring 31 is rotatably arranged inside the housing of the handle 10 through the central axis 11.

[0029] A motor mounting seat 13 is provided on the housing of the handle 10. The motor mounting seat 13 can be formed by a protrusion provided inside the housing or by a groove provided on the housing.

[0030] The motor assembly 32 can drive the transmission gear 331 to rotate left and right. The transmission gear 331 transmits the driving force to the driving gear 332. Then, the driving gear 332 drives the wire fixing ring 31 to rotate. The rotation direction of the wire fixing ring 31 makes the snake bone 21 wire tightened or relaxed, driving the snake bone 21 to bend or reset.

[0031] A rib 34 is provided on the driving gear 332, and a limit cut-off switch 35 is provided on the handle 10. When the rib 34 touches the limit cut-off switch 35, the motor assembly 32 stops rotating in the current rotation direction and stops driving the bending of the snake bone 21 to prevent the snake bone 21 from being damaged due to excessive bending.

[0032] The limit cut-off switch 35 can be an upper limit switch and a lower limit switch, respectively indicating on both sides of the central position, and is used to limit the maximum rotation angles of the driving gear 332 rotating left and right.

[0033] The motor assembly 32 can be an encoder motor. When the rib 34 touches the limit cut-off switch 35, the encoder on the encoder motor can calculate the reset position according to the stroke of the rib 34. By issuing a reset instruction, the encoder motor can drive the snake bone 21 to reset. The encoder motor uses a commercially available encoder motor, and this function can be achieved through parameter settings, without involving improvements in programs or methods.

[0034] Through the driving mode of the motor assembly 32, compared with the traditional manual driving mode, the driving mode of the motor assembly 32 is more accurate, saves the force required for the user's manual driving, and greatly improves the user experience of the product.

[0035] The wire fixing ring 31 and the driving gear 332 can be connected in a snap-fit manner, or the wire fixing ring 31 and the driving gear 332 can be integrally formed.

[0036] The driving gear 332 can drive the wire fixing ring 31 to rotate left and right and reset, pulling the wire of the snake bone 21 to drive the snake bone 21 to bend, adjusting the turning direction and turning angle of the snake bone 211 to complete the omnidirectional observation of the cavity and the delivery of the instrument. After the operation is completed, the snake bone 21 can be controlled to return from the bent state to the stretched state, so as to reduce the pulling of the body tissue of the user by the snake bone 21 during movement and avoid causing harm to the patient during the operation.

[0037] A button 12 can be provided on the handle 10, and the button 12 can be used to issue control instructions for the left-turn button, right-turn button, and reset button. In a preferred embodiment, there can be three buttons, namely the left-turn, right-turn, and reset buttons.

[0038] The central shaft 11 can be a hollow structure, and the wire fixing ring 31 and the driving gear 332 are rotatably fitted on the outer periphery of the central shaft 11.

[0039] A part of the wire fixing ring 31 extends to the outside of the housing of the handle 10. An indication mark can be provided on the wire fixing ring 31. The indication mark can be an arrow or other symbols indicating directions. The rotation direction of the wire fixing ring 31 can be directly displayed through the indication mark.

[0040] The housing of the handle 10 can be correspondingly provided with the mark description to intuitively explain the meaning indicated by the indication mark.

[0041] As Figures 5 - 6 As shown, the motor assembly 32 is detachably mounted on the handle 10. Specifically, the motor assembly 32 is encapsulated in a box body 321. The handle 10 correspondingly has a motor mounting seat 13 formed by a groove on the housing. The motor assembly 32 is detachably accommodated in the motor mounting seat 13, and the transmission gear 331 is connected to the output shaft of the motor assembly 32.

[0042] In some embodiments, the motor assembly 32 and the transmission gear 331 are detachably mounted on the handle 10. The motor assembly 32 and the transmission gear 331 are encapsulated in a box body 321. The handle 10 correspondingly has a motor mounting seat 13 formed by a groove on the housing. The motor assembly 32 is detachably accommodated in the mounting groove, and the transmission gear 331 is meshed and connected with the driving gear 332.

[0043] A cover plate 14 is provided on the motor mounting seat 13. The cover plate 14 has two states of opening and closing. The cover plate 14 can be snap-connected or magnetically connected to the handle 10.

[0044] The endoscope further includes one or more of a 5G / 6G wireless transmission module, a Bluetooth module, and a Wi-Fi module, which serve as control media for telemedicine, enabling remote guidance or intraoperative interaction, etc. The 5G / 6G wireless transmission module, the Bluetooth module, and the Wi-Fi module can be disposed within the handle 10 or within the detachable motor assembly 32.

[0045] In some embodiments, the motor assembly 32 includes a motor reduction gearbox that can be fixed in any adjusted position to prevent rebound, eliminating the need for the operator to apply a driving force to control the position of the drive gear 332, thereby enhancing the convenience and safety of operation.
