Description

Technical Field

[0001] The invention belongs to the technical field of endoscopes, and in particular to an endoscope operation auxiliary stabilizer. Background Art

[0002] An endoscope generally refers to a medical instrument that enters the human body through various tubes to observe the internal conditions of the human body. An endoscope can be used to see lesions that cannot be shown by X-rays, so it is very useful to doctors. For example, with the help of an endoscope, doctors can observe ulcers or tumors in the stomach and develop the best treatment plan accordingly.

[0003] In the prior art, announcement number CN112754399A provides an endoscope fixing bracket, including an endoscope clamp, a first connecting rod, a second connecting rod and a handle fixing rod. The handle fixing rod is arranged in the left and right directions, and the right end of the handle fixing rod is used to fix the duodenoscope in the left and right directions. The first connecting rod and the second connecting rod are both arranged vertically, the lower end of the second connecting rod is connected to the left end of the handle fixing rod, the lower end of the first connecting rod is connected to the upper end of the second connecting rod, and the endoscope clamp is arranged at the upper end of the first connecting rod. The endoscope clamp is used to clamp the endoscope so as to fix the endoscope in the left and right directions so that the endoscope is located above the duodenoscope. Preferably, the lower end of the second connecting rod can be rotatably connected to the left end of the handle fixing rod in the front-to-back direction, and the lower end of the first connecting rod can be rotatably connected to the upper end of the second connecting rod in the front-to-back direction. The endoscope fixing bracket of this invention can make the bending amplitude of the mother-and-child scope insertion tube small and the bending length short, will not interfere with the inspection, and is easy to use.

[0004] The above patented endoscope fixing bracket can make the bending range of the mother-and-child endoscope insertion tube small and the bending length short, which will not interfere with the examination and is easy to use. However, the endoscope fixing bracket still has some problems;

[0005] 1. During the insertion of the endoscope, the patient's mouth needs to be kept open. If the patient's mouth is closed during the insertion of the endoscope, it will affect the normal insertion of the endoscope and make the insertion operation difficult.

[0006] 2. The endoscope fixing bracket is to insert the endoscope into the oral cavity and then fix it externally. During the fixation process, the inner cavity is prone to displacement, resulting in inaccurate detection.

[0007] Therefore, in order to solve the above problems, an endoscope operation auxiliary stabilizer is proposed. Summary of the Invention

[0021] 2. The present invention rotates the worm to drive the worm wheel, which in turn drives the arc rod and the clamping block to rotate, thereby fine-tuning the angle of the endoscope and improving the accuracy of endoscopic detection.

[0022] 3. The present invention adopts the linkage of the worm and the worm wheel. The worm and the worm wheel have the characteristic of reverse transmission locking, which can prevent the arc rod from rotating, causing the endoscope observation angle to shift and interfere with the inspection.

A second threaded rod 6 is movably provided at the rear end of the clamping block 5. A worm gear 4 is provided on the right side of the movable frame 2, and a worm 3 is movably installed on the right side of the fixed frame 1.

[0035] The fixing frame 1 includes a first fixing rod 101 and a second fixing rod 102, and the first fixing rod 101 and the second fixing rod 102 are arranged parallel to each other. The bottoms of the first fixing rod 101 and the second fixing rod 102 are respectively fixedly connected to two clamping blocks 103, and the clamping blocks 103 are arc-shaped structures;

[0036] The upper left end of the first fixing rod 101 is rotatably connected to the first threaded rod 104, and the rear end of the first threaded rod 104 is rotatably connected to the left end of the second fixing rod 102. The upper right end of the first fixing rod 101 is fixedly connected to the limiting rod 105, and the limiting rod 105 is slidably connected to the right end of the second fixing rod 102.

[0037] Specifically, the two clamping blocks 103 are engaged with the patient's teeth to fix the stabilizer as a whole in the patient's mouth. The rotation of the first threaded rod 104 drives the first fixed rod 101 and the second fixed rod 102 to move toward or away from each other, thereby stretching the patient's mouth and facilitating the stable insertion of the endoscope into the patient's mouth.

[0038] like Figure 1 、 Figure 2 and Figure 3 As shown, the movable frame 2 includes an arc-shaped rod 201, in which two sliding grooves 202 are symmetrically provided. The left and right outer walls of the arc-shaped rod 201 are respectively fixedly connected to a rotating shaft 203, and the two rotating shafts 203 are respectively rotatably connected to the left upper portion and the right upper portion of the first fixed rod 101;

[0039] Specifically, the first fixing rod 101 is rotatably connected to the two rotating shafts 203 respectively to limit and fix the arc rod 201, and at the same time, the arc rod 201 can be rotated to adjust the angle of the arc rod 201.

[0041] Specifically, the two sliding grooves 202 respectively accommodate the two clamping blocks 5.

[0042] like Figure 3 and Figure 4As shown, the middle portion of the second threaded rod 6 is rotatably connected to the rear side of the arc-shaped rod 201, and the left and right ends of the second threaded rod 6 are respectively threadedly connected to the rear ends of the two clamping blocks 5, and the two clamping blocks 5 move toward or away from each other;

[0043] Specifically, the second threaded rod 6 is rotated to drive the two clamping blocks 5 to move toward each other, thereby clamping and fixing the endoscope to maintain stable endoscope observation.

[0044] like Figure 1 、 Figure 2 and Figure 3 As shown, the worm wheel 4 is fixedly connected to the right end of the right rotating shaft 203, and the upper and lower ends of the worm 3 are rotatably connected to the upper right end of the first fixed rod 101, and the worm 3 is meshed with the worm wheel 4;

[0045] Specifically, the rotation of the worm 3 drives the worm wheel 4 to rotate, which in turn drives the arc rod 201 and the two clamping blocks 5 to rotate, and then drives the endoscope clamped by the two clamping blocks 5 to rotate, fine-tuning the angle of the endoscope and improving the accuracy of endoscopic detection.

[0046] Working principle: When using the endoscope to operate the auxiliary stabilizer, first open the patient's mouth and insert the stabilizer into the patient's mouth so that the block 103 engages with the patient's teeth. Secondly, rotate the first threaded rod 104 to drive the first fixed rod 101 and the second fixed rod 102 to move toward or away from each other, so as to open the patient's mouth and facilitate the insertion of the endoscope. Secondly, after inserting the endoscope, rotate the second threaded rod 6 to drive the two clamping blocks 5 to move toward each other, clamp the endoscope, and make the endoscopic observation more stable. Then, rotate the worm 3 to drive the worm wheel 4 to rotate, and then drive the arc rod 201 and the two clamping blocks 5 to rotate, adjust the angle of the arc rod 201 and the two clamping blocks 5, and then adjust the angle of the endoscope and fine-tune the angle of the endoscope.
