Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and specifically refers to a device for assisting abdominal compression during colonoscopy. Background Art

[0002] During the intestinal disease examination, colonoscopy may be involved. Colonoscopy can observe the internal structure of the intestine. The development of certain lesions can also be known through this examination. It is also a relatively effective method for screening intestinal examinations. For colonoscopy, a colonoscope needs to be used to enter the patient's intestine from the anus, and the intestine has many bends. When the colonoscope passes through some bends, medical staff often need to press the patient's abdomen from different angles to change the internal intestinal bends and help the colonoscope pass. The scene examination generally takes about 30 minutes. During the operation, medical staff continue to press the patient's abdomen, which is quite tiring. At the same time, during the colonoscopy, if a patient is sensitive to pain or too nervous, he needs to be anesthetized. During the colonoscopy, the patient is often required to turn over and switch between lying on the left side and lying flat. For anesthetized patients, medical staff often need to manually help turn over, which is cumbersome. Summary of the invention

At the same time, motor three is started to control the extension shaft to flip the arc rod downward to facilitate the patient's entry. The auxiliary mechanism is then reset and the positioning track is reinstalled into track groove one. When performing a colonoscopy, motor three controls the arc rod to prop up the patient's legs and fix the patient's knees in the recessed part to facilitate surgery. When the patient needs to turn over, the electric roller rotates in the same direction, pulling the cotton towel to assist the patient's torso to move.

When the patient needs to perform abdominal compression on the patient, the position and angle of the abdominal compression mechanism can be flexibly adjusted through the handle. The electric telescopic rod 1 sends the compression head to the patient's abdomen, the motor 2 is started, and the card shaft drives the screw to move the compression head downward to squeeze the patient's abdomen. At the same time, when micro-manipulation is needed, the electric telescopic rod 2 is extended to make the cylinder body shift to both sides to adjust the abdominal compression angle. At the same time, when the patient is in the left side lying position, the electric telescopic rod 2 can continue to extend so that the compression head faces obliquely upward, and the left half of the patient's abdomen is pressed in a hook-pull manner when the patient is lying on the left side. This method can assist medical staff in turning the patient over, and can also replace the manual pressing method. The medical staff only needs to adjust the pressing mechanism, which can greatly reduce the physical consumption of medical staff and reduce the pressure on medical staff.

[0040] The arc rod 704 is symmetrically provided with recessed portions 705 .

[0041] Before use, first remove the positioning track 5 and the abdominal compression mechanism 6, then start the motor 1 403 to control the bottom end of the L-shaped rod 404 to flip the auxiliary mechanism 4 downward, and at the same time start the motor 3 702 to control the extension shaft 703 to flip the arc rod 704 downward to facilitate the patient's entry, then control the motor 1 403 and the motor 3 702 to reset the auxiliary mechanism 4 and reinstall the positioning track 5 into the track groove 1 407. Before the operation, start the motor 3 702 to prop up the arc rod 704 upward, and the arc rod 704 supports the patient's legs and puts the patient's knees into the recessed part 705 to fix it. The legs do not block the colonoscopy equipment, which facilitates surgery. When the anesthetized patient needs to turn over, the electric roller 103 rotates in the same direction, pulling the cotton towel 3 to assist the patient's trunk to move. At the same time, when the patient's trunk contacts the turning roller 405, the turning roller 405 blocks the upper part of the patient's trunk at the top, and cooperates with the bottom cotton towel 3 to drag at the bottom to make the patient's trunk roll, assisting the patient to turn over. At the same time, the patient's legs can slide along the arc rod 704 to the turning side to prevent the surgical instruments from being affected during the turning process. During the operation, when the patient needs to be compressed in the abdomen, the handle 605 is used to flexibly adjust the abdominal compression mechanism 6 to make it move along the track groove 407. The position and angle of the abdominal compression mechanism 6 can be flexibly adjusted by moving it forward and backward in the direction of the second track groove 502, moving it left and right in the direction of the second track groove 502, or rotating in the through hole 603. When it moves to the position where the abdominal compression is required, the electric telescopic rod 1 606 is extended to send the pressure head 620 to the patient's abdomen. Then the motor 2 616 is started, and the card shaft 617 drives the screw 618. The screw 618 moves downward in the screw hole 615 to move the pressure head 620 downward to squeeze the patient's abdomen. At the same time, when micro-adjustment is needed, the electric telescopic rod 2 611 is controlled to extend to make the cylinder 613 swing to both sides. When the cylinder 613 is required to move to the left When swinging, the electric telescopic rod three 612 on the right side of the electric telescopic rod two 611 extends and presses upward against the bottom plate 607, so that the electric telescopic rod two 611 cannot swing to the right. When the cylinder 613 needs to swing to the right, the electric telescopic rod three 612 on the left side of the electric telescopic rod two 611 extends and presses upward against the bottom plate 607, so that the cylinder 613 cannot swing to the left, thereby adjusting the abdominal compression angle. At the same time, when the patient is in the left side lying position, the electric telescopic rod two 611 can continue to extend according to the actual situation, so that the reversal angle of the pressure head 620 exceeds 90°, and the left half of the patient's abdomen is pressed by hooking and pulling when the patient is lying on the left side.
