Description

Technical Field

[0001] This utility model belongs to the field of digestive endoscopy technology, specifically, it relates to a digestive endoscope angle adjustment and locking structure. Background Technology

[0002] A digestive endoscope is a medical device primarily used for the examination and treatment of digestive system diseases. It's a device that allows observation inside the human digestive tract (including the esophagus, stomach, duodenum, small intestine, and large intestine). It typically uses optical or electronic imaging technology to transmit images of the digestive tract's interior to an external display device, allowing doctors to directly observe the condition of the mucosa, blood vessel distribution, and the presence of lesions (such as ulcers, polyps, and tumors). Digestive endoscopy can directly observe minute lesions within the digestive tract; for example, early gastric cancer may only manifest as tiny depressions or bulges in the gastric mucosa, which can be detected promptly using a gastroscopy. Digestive endoscopy also offers unique advantages for lesions that are difficult to detect using other methods (such as X-rays and ultrasound).

[0003] During the use of digestive endoscopes, it is difficult to keep the adjustment rod stable at a specific angle, making it difficult for doctors to maintain a clear and accurate field of vision. This may result in missing lesions or requiring frequent readjustment of the angle during the operation, increasing operation time and patient discomfort. Utility Model Content

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0031] like Figure 1-5 The diagram shows a first embodiment of a digestive endoscope angle adjustment and locking structure provided by this utility model. In this embodiment, it includes a mounting base 1 and an adjustment mechanism 2. The mounting base 1 has a square structure and is used to place the adjustment rod of the digestive endoscope. The adjustment mechanism 2 is located on the front side of the mounting base 1 and is used to fix the adjustment rod of the digestive endoscope to prevent displacement. The mounting base 1 includes a first fixing hole 11, a positioning plate 12, a protrusion 13, a screw 14, and a nut 15. The positioning plate 12 has a square structure. The protrusion 13 has a cylindrical structure. There are two protrusions 13, which are respectively located on the upper left and lower right parts of the positioning plate 12 and are fixedly connected to the front wall of the positioning plate 12. There are two first fixing holes 11, which are respectively located on the upper left and lower right corners of the positioning plate 12. The cross-section of the nut 15 is T-shaped, and there are four nuts. The nuts 15 are sleeved on the front and rear ends of the screw 14. The inner diameter of the nut 15 is equal to the outer diameter of the screw 14.

[0032] In use, first place the adjusting rod of the digestive endoscope in a suitable position on the positioning plate 12 of the mounting base 1, so that the screw 14 passes through the first fixing hole 11 and the corresponding second fixing hole 25 and third fixing hole 26 on the adjusting plate 21. Then, put the nuts 15 on the front and rear ends of the screw 14 and tighten them to complete the initial installation of the digestive endoscope adjusting rod and the device. Rotate the rotating frame 24. Since the rotating frame 24 is movably connected to the limiting frame 22 and swings left and right around the protrusion 13, which is located in the arc-shaped through groove of the adjusting plate 21, the rotation of the rotating frame 24 drives the adjusting rod to change the angle within the range allowed by the arc-shaped through groove. At the same time, due to the limiting effect of the limiting frame 22, the angle adjustment process is smooth and precise. When the appropriate angle is adjusted, due to the friction between the components of the adjusting mechanism 2 and the design of the overall structure, the adjusting rod is automatically locked at that angle position to prevent displacement. During operation, if subjected to external impact, the stable structure of the mounting base 1 and the adjusting mechanism 2 and the cooperation between the components can maintain the locked state to ensure the stability of the endoscope angle.

The upper side wall and the left side wall of the upper left adjustment plate 21 are flush with the upper edge and the left edge of the positioning plate 12, respectively, and the lower side wall and the right side wall of the lower right adjustment plate 21 are flush with the lower edge and the right edge of the positioning plate 12, respectively. The two adjustment plates 21 are centrally symmetrical.

[0034] Furthermore, in the above technical solution, the limiting frame 22 has a U-shaped structure, with connecting rods 23 fixedly installed on the left and right sides, and the cross-section of the limiting frame 22 has a C-shaped structure; the limiting frame 22 is inclinedly installed on the front side of the adjusting plate 21, and the upper and lower ends of the limiting frame 22 are fixedly connected to the front wall of the adjusting plate 21; the interior of the adjusting plate 21 is provided with an arc-shaped through groove; the inclination angle of the limiting frame 22 is equal to the inclination angle of the arc-shaped through groove.

[0035] Furthermore, in the above technical solution, the rotating frame 24 is located on the front side of the limiting frame 22. The rotating frame 24 has a U-shaped structure, and the two sides of the rotating frame 24 pass through the left and right connecting rods 23 of the limiting frame 22 respectively. The rotating frame 24 swings left and right around the protrusion 13. The rotating frame 24 is movably connected to the limiting frame 22. The protrusion 13 is located inside the arc-shaped through groove of the adjusting plate 21. The two ends of the arc-shaped through groove are equidistant from the hinge point of the positioning plate 12 and the adjusting plate 21.

[0036] Furthermore, in the above technical solution, two connecting rods 23 are provided at the top and bottom of the rotating frame 24, and the connecting rods 23 pass through the upper and lower ends of the limiting frame 22 and are fixedly connected to the side wall of the rotating frame 24.

[0037] Furthermore, in the above technical solution, the upper left adjustment plate 21 is hinged to the lower left corner of the positioning plate 12, and the lower right adjustment plate 21 is hinged to the lower right corner of the positioning plate 12.

[0038] Furthermore, in the above technical solution, the height of the adjusting plate 21 is 2 / 3 of the height of the positioning plate 12.

[0039] Furthermore, in the above technical solution, the second fixing hole 25 is located at the upper left corner of the adjusting plate 21.

[0040] Furthermore, in the above technical solution, the third fixing hole 26 is located at the lower right corner of the adjusting plate 21.

[0041] Furthermore, in the above technical solution, the screw 14 is inserted into the first fixing hole 11, the second fixing hole 25, and the third fixing hole 26.

[0042] Specifically, the principle of this utility model is as follows: First, the adjusting rod of the digestive endoscope is placed in a suitable position on the positioning plate 12 of the mounting base 1, so that the screw 14 passes through the first fixing hole 11 and the corresponding second fixing hole 25 and third fixing hole 26 on the adjusting plate 21. Then, nuts 15 are put on the front and rear ends of the screw 14 and tightened, completing the initial installation of the digestive endoscope adjusting rod and the device.
