Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a digestive endoscopy-assisted positioning device. Background Technology

[0002] Colonoscopy is a common endoscopic examination method for digestive system diseases. Usually, patients need to lie on their side with their knees bent to expose their buttocks to ensure that the colonoscope can be inserted smoothly for examination. Some patients choose painless colonoscopy because they are afraid of pain.

[0003] During painless colonoscopy, patients are under anesthesia and cannot actively cooperate with position adjustments. Furthermore, anesthetized patients are prone to unconsciously sliding or changing their posture, which may lead to difficulties in the examination, obstruction of intubation, and even increased medical risks. Currently, position adjustment and fixation require manual operation by multiple medical staff. Medical staff fix the patient in the "side-lying knee-flexed position" (the standard position for colonoscopy) by supporting the patient's back, pressing on the legs, or supporting the buttocks. However, prolonged operation (the average time for a single painless colonoscopy is 15-30 minutes) can easily lead to arm fatigue and weakened strength. The patient's body is prone to sliding towards the foot of the bed or the buttocks may shift, causing the colonoscope insertion angle to deviate from the course of the intestine. This necessitates repeated position adjustments, prolonging the examination time and increasing time and labor costs. To address this, we propose a digestive colonoscopy auxiliary position fixation device. Utility Model Content

[0004] The purpose of this invention is to provide a postural fixation device for gastrointestinal endoscopy, in order to solve the problems mentioned in the background art, such as the need for repeated adjustments of the patient's position, which prolongs the examination time and increases time and labor costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a digestive endoscopy-assisted positioning device, comprising a bed frame, legs at the four corners of the bottom of the bed frame, a leg fixing rotating component in the middle of the bed frame, a sliding block rotatably connected to the bottom of the leg fixing rotating component, the sliding block being slidably connected to the bed frame, a chest fixing rotating component rotatably connected to the bed frame away from the leg fixing rotating component, a drive mechanism at the bottom of the bed frame, and a pillow on the side of the bed frame away from the leg fixing rotating component.

[0006] The leg-fixing rotating component includes a leg support block, with a toothed groove at the bottom and rotating grooves on both sides.

[0007] The chest fixing and rotating component includes a chest support block, which has openings at both ends of the bottom and on both sides of the chest support block. The chest fixing and rotating component is slidably connected to the bed frame.

[0008] The drive mechanism includes a rotating rod, a short gear fixedly connected to the bottom of the rotating rod, a long gear fixedly connected to the bottom of the rotating rod, a servo motor rotatably connected to one end of the rotating rod, and cylinders fixedly connected to both sides of the bottom of the sliding block.

[0009] The sliding block has sliding holes on both sides, and the sliding block has a hollow structure. A limiting block is provided inside the sliding block, and the limiting block slides in the rotating groove.

[0010] The bed has a groove at the sliding block, and a sliding rod is provided inside the groove. The sliding rod passes through the sliding hole, and the sliding block is slidably connected to the bed through the sliding rod.

[0011] The leg support block has a pad in the middle, and the pad and the two sides of the leg support block are connected to the leg elastic straps. The two sides of the chest support block are connected to the chest elastic straps.

[0012] This utility model has at least the following beneficial effects: In use, this invention, through the cooperation of a servo motor and gear system, can adjust the patient from a supine to a lateral position in a short time, reducing the workload of medical staff. By using a cylinder to push a sliding block and a leg fixing rotating part, the knee flexion action is realized, allowing the patient to complete the lateral knee flexion position and expose the buttocks in an unconscious anesthesia state, and maintain it for a long time to facilitate long-term colonoscopy. Through mechanical and automated design, time and labor costs are reduced and examination efficiency is improved. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example 1 Please see Figures 1 to 4 This utility model provides a technical solution: a digestive endoscopy-assisted positioning device, including a bed 1, with four legs 2 at the bottom corners of the bed 1, and a leg fixing rotating member 3 in the middle of the bed 1. A sliding block 4 is rotatably connected to the bottom of the leg fixing rotating member 3 and is slidably connected to the bed 1. When the patient is in a lateral position, the sliding block 4 can slide and drive the leg fixing rotating member 3 to change the patient's knee flexion state, keeping the patient's knees bent. A chest fixing rotating member 5 is rotatably connected to the bed 1 away from the leg fixing rotating member 3. The simultaneous rotation of the chest fixing rotating member 5 and the leg fixing rotating member 3 can turn the patient from a supine position to a lateral position. A drive mechanism 6 is provided at the bottom of the bed 1. The drive mechanism 6 can simultaneously rotate the chest fixing rotating member 5 and the leg fixing rotating member 5 and can push the sliding block 4. A pillow 7 is provided on the side of the bed 1 away from the chest fixing rotating member 5 and the leg fixing rotating member 3. The pillow 7 can provide support for the head or upper body when lying on the side, preventing discomfort caused by prolonged pressure during anesthesia.

[0016] The bed frame 1 has a groove at the sliding block 4, and a sliding rod 11 is provided inside the groove. Sliding holes 41 are provided on both sides of the sliding block 4. The sliding block 4 has a hollow structure, and a limiting block 42 is provided inside the sliding block 4. The sliding rod 11 passes through the sliding hole 41, and the sliding block 4 is slidably connected to the bed frame 1 via the sliding rod 11. By sliding the sliding block 4 on the sliding rod 11 in the groove of the bed frame 1, the position of the leg fixing rotating component 3 can be adjusted. The leg fixing rotating component 3 includes a leg support block 31, and elastic leg straps 312 are connected to both sides of the leg support block 31. The elastic leg straps 312 provide flexible restraint to the patient's legs to prevent unconscious movement. A toothed groove 32 is provided at the bottom of the leg support block 31, and rotating grooves 33 are provided on both sides of the leg support block 31. The limiting block 42 slides within the rotating groove 33. The limiting block 34 and the groove 33 ensure that the leg fixing rotating component 3 only rotates along the direction of the groove. The chest fixing rotating component 5 includes a chest support block. 51 provides support for the patient's chest. Elastic chest straps 511 are connected to both sides of the chest support block 51 to stabilize the patient's upper body and ensure the chest is maintained in the required position for the side-lying position. Chest toothed grooves 52 are provided at both ends of the bottom of the chest support block 51, and chest sliding grooves 53 are provided on both sides of the chest support block 51. The chest fixing rotating component 5 is slidably connected to the bed frame 1 through the chest sliding grooves 53. The chest sliding grooves 53 can limit the rotation trajectory of the chest fixing rotating component. The drive mechanism 6 includes a rotating rod 61. A short gear 62 is fixedly connected to the bottom of the chest toothed groove 52, and a long gear 63 is fixedly connected to the bottom of the toothed groove 32. The long gear 63 can still mesh with the leg sliding groove 33 after the sliding block 4 slides, to ensure subsequent restoration of the body position. A servo motor 64 is rotatably connected to one end of the rotating rod 61 as the drive device for the rotating rod 61. The servo motor 64 can achieve precise rotation and prevent excessive rotation from causing injury to the patient.

[0017] The working principle of this invention is as follows: After the patient is anesthetized, medical staff have the patient lie flat on the bed 1 with their head resting on the pillow 7, their chest held within the chest fixing rotating part 5, and their knees placed within the leg fixing rotating part 3. The patient is then flexibly secured using elastic straps 511 on the chest and 312 on the legs. At this time, the servo motor 64 is activated to rotate the rotating rod 61. The short gear 62 and long gear 63 of the rotating rod 61 simultaneously rotate the chest fixing rotating part 5 and the leg fixing rotating part 3, changing the patient from a supine to a lateral position. Then, the cylinder 65 is activated to push the sliding block 4, which in turn slides the leg fixing rotating part 3, causing the patient's knees to bend, completing the lateral knee-bent position to expose the buttocks. During the examination, the cylinder and servo motor are locked to maintain the patient's position, facilitating operation by medical staff. After the examination, the servo motor 64 and cylinder 65 are reversed to reset.

[0018] Example 2 Please see Figure 4In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that the leg support block 31 is provided with a pad 311 in the middle. When the patient is under anesthesia and maintains a side-lying position for a long time during colonoscopy, the pad 311 can provide protection for the patient's knees and prevent pressure sores caused by prolonged pressure.
