Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an electric control device for an endoscope. Background Technology

[0002] An endoscope is a diagnostic and therapeutic instrument that integrates traditional optics, ergonomics, precision mechanics, modern electronics, mathematics, and software. It can enter the stomach through the mouth or other orifices into the human body. Endoscopes can be used to see lesions that cannot be seen by X-rays.

[0003] To meet the requirement that the active bending section of an endoscope can bend in four directions, large and small dials are usually provided. Currently, when using an endoscope, doctors generally need to manually rotate the large and small dials to control the left-right and back-forward swing of the endoscope tip. Automated and remote control is not possible, and manual control relies entirely on the doctor's feel and experience, without any quantitative numerical feedback, resulting in uncontrollability during operation.

[0039] To facilitate the lateral sliding of the endoscope, the endoscope fixing quick-release assembly also includes a slide rail module 38, an inner slide rail fixing seat 42, and an outer slide rail fixing seat 39. The slide rail module 38 includes a slide rail 381 and a slider 382 disposed on the slide rail 381. The slider 382 is fixed inside the endoscope lower clamping block 34 and is used to drive the endoscope to slide laterally.

The inner slide rail fixing seat 42 is provided with an oblong through hole 70.

[0040] The endoscope fixation quick-release assembly also includes a constant force spring 45, a rack 56, and a damping gear 48. The damping gear 48 is located below the endoscope lower clamp 34 and meshes with the rack 56. The constant force spring 45 is sleeved on the outside of the bushing 49. The bushing 49 is fixed to the lower part of the endoscope lower clamp 34 by a flat-head screw 46. One end of the constant force spring 45 is stretched and fixed to the outer slide rail fixing seat 39 by a screw.

[0041] To clamp and secure the endoscope, the endoscope quick-release assembly also includes an upper endoscope clamp 35. The rear end of the upper endoscope clamp 35 is rotatably connected to the inner slide rail fixing seat 42 via a pin 41. A compression spring is inserted between the inner slide rail fixing seat 42 and the upper endoscope clamp 35. The upper endoscope clamp 35 can be rotated to cover the upper side of the lower endoscope clamp 34 to form a U-shaped hole for clamping the endoscope. A shoulder screw 44 is also fixed at the lower rear of the upper endoscope clamp 35, which passes through the waist-shaped through hole 70 of the inner slide rail fixing seat 42. The shoulder screw 44 can move within the waist-shaped through hole 70 to limit the rotation range of the upper endoscope clamp 35.

[0042] One operational description of this invention is as follows: The endoscope 5 is secured to the lower endoscope clamp 34. The lower endoscope clamp 34 is pushed until the upper endoscope clamp 35 rotates and presses the endoscope 5 firmly. Simultaneously, a sound can be heard indicating that the magnet 53 on the upper section 54 of the self-locking linkage attracts and collides with the magnet 53 on the magnetic switch base 62, signifying that the endoscope 5 is properly installed. The rotary switch 63 is then rotated to engage the locking rotary shaft 60 into the groove of the upper section 54 of the self-locking linkage, preventing external interference from causing the magnetic attraction to disengage. Then, the rotation of the motor 6 sequentially drives the small gear 12, the large gear 13, and the belt pulley 9, thereby driving the small knob drive disk 33 controlled by belt one, and the large knob drive disk 31 controlled by belt two. A clicking sound during rotation indicates that the endoscope's large and small discs are engaged in the knob drive disks, allowing normal operation of the endoscope's head end via the program. When used in conjunction with a control panel, remote control or automatic program control of the endoscope's movement can be achieved. To prevent damage to the internal structure of the endoscope due to excessive torque transmitted to the large and small knobs, the tension of belts 3 and 4 can be adjusted by tightening screw 17. When the endoscope's large and small discs have reached their limits, the torque is released by slipping belts 3 and 4. After use, turn the rotary switch 63 to unlock, and press button 69 to push open the lower section 55 of the self-locking linkage via switch shaft 66, disengaging the two magnets. Under the tension of constant force spring 45, the lower endoscope clamp 34 slides the endoscope outward. To prevent the endoscope from sliding too quickly and causing an impact, the travel is slowly released by the engagement of damping gear 48 and rack 56.

[0043] As can be seen from the above, the present invention controls the endoscope by mechanically connecting the large and small wheels of the endoscope, thereby realizing automated and remote control; the rotation of the large and small wheels of the endoscope is controlled by a motor, and the rotation angle of the wheels is fed back in real time by the encoder of the motor, which quantifies the control of the endoscope and effectively improves the operating accuracy and efficiency of the endoscope.

[0044] This invention provides an endoscope, including the endoscope electric control device as described above, the specific structure of which will not be repeated here.
