Description

Technical Field

[0001] This invention relates to the field of gastroenterology, specifically to an auxiliary guiding device for gastrointestinal endoscopy. Background Technology

[0002] Digestive endoscopy is a medical diagnostic and treatment method. It involves inserting an endoscope and a cannula into the patient's digestive tract. The endoscope, equipped with a miniature camera and a light guide lens at its tip, provides a clear view during the examination. The camera allows doctors to directly observe the internal structure of the esophagus, stomach, duodenum, and colon, detecting problems such as inflammation, ulcers, polyps, and tumors. Biopsies or treatments can also be performed under direct vision. During the examination, the doctor typically uses a control handle to adjust the direction of the cannula, allowing the endoscope to slowly enter the patient's body. During advancement, the doctor uses the control handle to adjust the angle of the endoscope's tip to accommodate the curved structure of the digestive tract. Simultaneously, the doctor monitors the images transmitted from the endoscope's tip in real time to precisely control the insertion depth and direction, avoiding damage to the digestive tract wall. When the light guide lens becomes blurry, a water pump is activated to deliver water to the flushing tube, which sprays water to rinse the light guide lens. However, because the movement of the endoscope inside the patient relies entirely on manual control by the doctor, prolonged handheld operation can lead to fatigue. Furthermore, the endoscope's tip is prone to bending or curling during movement, requiring timely rotation to eliminate any obstructions and ensure proper movement. Summary of the Invention

The structure includes: a base frame 1 with four corner supports on its lower side and four vertical main supports 2 on its upper side; an upper frame 3 with a rectangular frame installed at the top of the main supports 2, with several parallel upper connecting rods 4 inside, and several mounting holes 5 evenly spaced on the upper connecting rods 4; an upper mounting plate 6 with four corner mounting plate adjusting posts 7 on its lower side, which pass through the mounting holes 5 and are secured by mounting plate locking nuts 8 on both the upper and lower sides; a support block mounting base 9 is attached to the upper frame 3 and secured by base locking screws 10, with a support block bracket 11 installed on its upper side; and a support block adjusting rod 13 is installed on the support block bracket 11, with a support block adjusting rod 13 on its lower side. 3. After passing through the support bracket 11, nuts are installed on both the upper and lower sides for locking and fixing; the limiting block support column 14 is installed on the center of the front side of the upper side of the upper frame 3, and a limiting block 15 is installed on it, and a limiting block pressing screw 16 is installed; the two ends of the side mounting plate fixing seat 17 are installed on the main support column 2 on the lower side of the limiting block support column 14, and are tightened and fixed with connecting bolts 18 and nuts, and a side mounting plate 19 is installed on its front side; a side support column 20 is installed on the front side of the lower side of the side mounting plate 19, and a screw hole is opened in the center of the lower side of the side support column 20. An adjusting support column 21 is installed in the screw hole and is fixed with an adjusting support column locking nut 22; the screw rod mounting bracket 23 is installed in pairs on the left and right sides of the upper side of the side mounting plate 19. The lead screw 24 is mounted on the lead screw mounting bracket 23 with bearings at both ends. The right lead screw 24 is connected to the shaft of the lead screw motor 27 by a coupling 26. Two lead screw sliders 25 are mounted on the lead screw 24. The slider connecting plate 28 is mounted on the two lead screw sliders 25 at both ends. The endoscope rotation mechanism is mounted on the slider connecting plate 28 and the upper mounting plate 6, including a seated bearing 29, an endoscope clamping seat 30, a clamping motor 31, a fixing screw seat 32, a driven gear 33, a motor mounting seat 34, a transmission motor 35, and a driving gear 36. The motor mounting seat 34 is located in front of the seated bearing 29, and the transmission motor 35 is mounted on it. The driving gear 36 is mounted on the shaft of the transmission motor 35.The endoscope holder 30 is mounted on a bearing 29 with a seat. Its front end is fitted with a driven gear 33, which meshes with the driving gear 36. A clamping motor 31 and a fixing screw seat 32 are fixedly mounted on the rear side. A stud is fitted onto the shaft of the clamping motor 31 and then onto the fixing screw seat 32. The mounting plate fixing seat 17 has a rectangular connecting rod as its main body. It has locking blocks on both the left and right sides of its rear side, with a groove in the center of each block. These blocks are engaged with the main support column 2. Connecting bolts 18 pass through both ends of the locking blocks and are secured with nuts. The mounting plate fixing seat 17 can be adjusted on the main support column 2 to accommodate beds of different heights, while ensuring the endoscope is inserted as straight as possible into the patient's body. The limiting block 15 is divided into upper and lower parts, each with a semi-circular notch running through its front and rear sides. The clamping screw 16 presses the two parts together from top to bottom, forming a circular notch in the center. The axis of this notch is parallel to the axis of the bearing 29 on the slider connecting plate 28. The diameter of this circular notch is larger than that of the endoscope, providing support and guiding limit for the endoscope, preventing large-scale movement or shaking during operation. The inner diameter of the annular part of the endoscope clamping seat 30 is larger than the inner diameter of the arc segment of the U-shaped part. The endoscope can be clamped by rotating the clamping motor 31 to tighten the U-shaped part, or by rotating the clamping motor 31 to open the U-shaped part, facilitating endoscope movement.

[0017] The working principle of this invention is as follows: Before use, the entire unit is moved to the bedside, and the support block mounting base 9 is fixed in a suitable position according to the doctor's operating habits. The height of the support block 12 is adjusted to support the doctor's left hand. Then, the support block 12 is locked, and the position of the side mounting plate fixing seat 17 is adjusted so that the height of the slider connecting plate 28 is appropriate. Then, the connecting bolt 18 is locked, and the adjusting support column 21 is moved so that it presses against the bed and the side mounting plate 19 is horizontal. Then, the adjusting support column locking nut 22 is locked. Then, the upper mounting plate 6 is brought close to the controller end and adjusted to a suitable height. The mounting plate locking nut 8 is then locked. Then, the endoscope is passed through the endoscope holder 30 on the upper mounting plate 6, through the central circular notch of the limiting block 15, and then through the endoscope holder 30 on the slider connecting plate 28 to complete the installation.

[0018] During the examination, the doctor holds the controller in their left hand and presses it against the support block 12, while operating the endoscope tip with their right hand. When the endoscope is moved normally, the U-shaped part of the endoscope clamp 30 is in the open state. After moving the endoscope a certain distance, the endoscope tip may bend and rotate due to manual control. At this time, the right hand grips the endoscope firmly, and simultaneously controls the clamping motor 31 to rotate forward. The stud on the motor passes through the fixing screw seat 32, clamping the U-shaped part and securing the endoscope. Then, as needed, the transmission motor 35 is controlled to rotate forward or backward, driving the endoscope to rotate and release the bent and rotated parts, preventing them from affecting the endoscope's movement. Then, the transmission motor 35 is stopped, and the clamping motor 31 is reversed, opening the U-shaped part of the endoscope clamp 30, allowing the endoscope to continue moving. When rotating the endoscope tip, the position of the slider connecting plate 28 can be moved according to the remaining length of the endoscope to more efficiently release the bent and rotated parts.

[0019] Components not described in detail in this article are existing technologies. The power cord of the clamping motor 31 is connected by a rotary joint. The control and wiring of each motor are conventional techniques used by those skilled in the art. The switches are combined on an operation panel and fixed on the upper frame 3 or the base frame 1.

[0020] While the specific embodiments of the present invention have been described in detail above, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention, and modifications or variations without creative effort are still within the protection scope of the present invention.
