Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and specifically discloses a digestive endoscopy stent. Background Technology
[0002] Gastrointestinal endoscopy is an examination method that uses an endoscope to examine lesions inside the digestive tract. It allows direct observation of the digestive tract mucosa, detection of lesions, and sampling for examination, which helps in the diagnosis and treatment of digestive tract diseases. It is applicable to the diagnosis and treatment of gastrointestinal diseases such as gastritis, gastric ulcers, esophageal cancer, and colon cancer. For upper gastrointestinal tract endoscopy, the endoscope tube is usually inserted into the patient's mouth. The doctor holds the endoscope's controller, and the endoscope tip takes pictures of the inside of the digestive tract, which are then displayed on a monitor. The doctor controls the endoscope to perform the examination based on the video content.
[0003] For example, Chinese patent CN217744322U discloses an angle-adjustable digestive endoscopy stent, including a fixed base, a first stent, a second stent, a third stent, a clamping plate, a moving block, and a telescopic cylinder. The telescopic cylinder is provided on one side of the fixed base, the moving block is provided on one side of the telescopic cylinder, the first stent is provided at the upper end of the moving block, the second stent is provided on one side of the first stent, the third stent is provided on one side of the second stent, a turntable is provided on one side of the third stent, and a clamping plate is provided on one side of the turntable. This utility model has the function of conveniently adjusting the clamping position, which solves the problem that existing digestive endoscopy stents lack effective fixation and rotation, resulting in limited angle adjustment, affecting the support effect of the stent, and thus affecting the doctor's treatment status.
[0004] However, the above-mentioned device still has the following problems in actual use: Although the angle of the digestive endoscope stent can be adjusted during use, it cannot be raised or lowered, so patients need to use it according to the height of the digestive endoscope stent. In addition, the endoscope tube is fixed on the digestive endoscope stent and does not have a disassembly function, so when encountering patients with limited mobility or special conditions, the endoscope tube cannot be disassembled in time for use. Therefore, we propose a digestive endoscope stent. Utility Model Content

A connecting rod 11 is rotatably provided at the output end of the second lifting device 10. One end of the connecting rod 11 is connected to the crossbeam 3.
[0025] In this embodiment: the base 1 fixes the longitudinal frame 2, and the clamping mechanism 4 at one end of the crossbeam 3 can clamp and support the endoscope tube, solving the problem of excessive arm strain and muscle fatigue caused by doctors holding the endoscope tube, and reducing the workload of medical staff; the crossbeam 3 also supports the endoscope tube, preventing it from colliding with the longitudinal frame 2; by activating the first lifting device 7, the sliding frame 6 slides within the fixed frame 5, making it easy to adjust the height of the support, allowing staff to adjust the height of the digestive endoscope support according to their own needs, improving the efficiency of the support, and also solving the problem for staff and meeting their needs; and by activating the second lifting device 10, the crossbeam 3 is pulled between the two support plates 8 by the connecting rod 11, making it easy to adjust the angle of the crossbeam 3.
[0026] As a technical optimization of this utility model, the crossbeam 3 includes a fixed support arm 12 and a sliding support arm 13 that is slidably sleeved inside one end of the fixed support arm 12. The fixed support arm 12 is provided with a threaded rod 14 with a handle at one end. Both the fixed support arm 12 and the sliding support arm 13 have screw holes 15 that are adapted to the threaded rod 14 on their outer surfaces. One end of the threaded rod 14 is threaded into one of the screw holes 15 on the fixed support arm 12 and the sliding support arm 13. The end of the fixed support arm 12 away from the sliding support arm 13 is fixedly connected to the connecting rod 11.
[0027] In this embodiment: the threaded rod 14 is removed from the threaded hole 15, making it easy to pull and adjust the length of the crossbeam 3. After adjustment, the threaded rod 14 is installed in the threaded hole to fix the sliding support arm 13, ensuring that the sliding support arm 13 will not slide arbitrarily, so that the length of the crossbeam 3 can be adjusted.
[0028] As a technical optimization of this utility model, the clamping mechanism 4 includes a mounting base 16 and clamping bases 17; one end of the sliding support arm 13 is fixedly connected to the center of the mounting base 16, and the clamping bases 17 are symmetrically arranged in groups on the other side of the mounting base 16, with V-shaped slots 18 on opposite sides of the two clamping bases 17; a dovetail groove 19 is opened on the side of the mounting base 16 facing the clamping base 17, and a bidirectional screw 20 and two dovetail sliders 21 are provided in the dovetail groove 19. The two ends of the bidirectional screw 20 are threaded through the dovetail sliders 21 and rotatably connected to the dovetail groove 19. The two dovetail sliders 21 are fixedly connected to the two clamping bases 17 respectively, and a handle fixedly connected to one end of the bidirectional screw 20 is provided on one side of the mounting base 16.
[0029] In this embodiment: rotating the handle on the bidirectional screw 20 causes the two dovetail sliders 21 to slide within the dovetail groove 19; when the dovetail sliders 21 slide, they simultaneously drive the two clamping seats 17 to move, making it easy to quickly disassemble the endoscope tube on the support, facilitating disassembly and assembly, and making it convenient for medical staff to hold the endoscope tube for use on patients; and the two clamping seats 17 can be adjusted by sliding to clamp and fix endoscope tubes of different sizes.
[0030] As a technical optimization of this utility model, a rubber pad 22 is provided inside the card slot 18.
[0031] In this embodiment: the rubber pad 22 has good elasticity and friction, which prevents the endoscope tube from sliding and improves the stability of clamping; and reduces the direct pressure of the clamping seat 17 on the endoscope tube, thereby reducing the risk of the endoscope tube surface being scratched or crushed.

[0036] Working principle and usage process of this utility model:
[0037] The base 1 secures the longitudinal frame 2, while the clamping mechanism 4 at one end of the crossbeam 3 holds and supports the endoscope tube, solving the problem of excessive arm strain and muscle fatigue caused by doctors holding the endoscope tube, thus reducing the workload of medical staff. Furthermore, the crossbeam 3 supports the endoscope tube, preventing it from colliding with the longitudinal frame 2. Activating the first lifting device 7 allows the sliding frame 6 to slide within the fixed frame 5, facilitating height adjustment. This allows staff to adjust the height of the endoscope stent according to their needs, improving stent utilization efficiency and eliminating inconvenience for staff. The staff's needs are met; and the second lifting device 10 is activated, which pulls the crossbeam 3 between the two support plates 8 through the connecting rod 11, making it easy to adjust the angle of the crossbeam 3; the handle on the bidirectional screw 20 is rotated, so that the two dovetail sliders 21 slide in the dovetail groove 19; when the dovetail sliders 21 slide, they simultaneously drive the two clamping seats 17 to move, making it easy to quickly remove the gastroscopy tube on the support, which is convenient for disassembly and assembly, and also makes it easy for medical staff to hold the gastroscopy tube for use on patients; and the two clamping seats 17 can be adjusted by sliding to clamp and fix gastroscopy tubes of different sizes.
