[0002] A medical endoscope is a medical device that can be inserted into a human cavity. It is equipped with a light source and an imaging system, and can clearly present the internal conditions of the human body. Through endoscopic examination, doctors can visually observe the surface morphology, color, structure, etc. of organs, thereby discovering potential lesions. At the same time, during surgery, the endoscope can also provide doctors with a surgical field of view, making it easier for medical staff to perform surgical operations. Endoscopes play a very important role in most surgeries.

DETAILED DESCRIPTION

[0026] Example 1

[0027] A multi-angle fixing device for an endoscope sleeve 5 comprises: a tightening belt 1, an adjustment component 3, and a fixing block 2; an arc groove 23 is provided on the outer wall of the fixing block 2, the tightening belt 1 passes through the arc groove 23 and is connected to the fixing block 2; the fixing block 2 is evenly fixed on the tightening belt 1, and a second adjustment knob 4 is fixedly installed at the end of the tightening belt 1; the tightening belt 1 is contracted by rotating and controlling the second adjustment knob 4, thereby controlling the fixing block 2 to clamp and fix the endoscope sleeve 5;

[0028] The upper end of the fixing block 2 is provided with a slot 21, on which the adjusting assembly 3 is detachably mounted, and the adjusting assembly 3 can be used to clamp and fix the endoscope 6, and when clamping and fixing, due to the setting of the non-uniform diameter through slot 333 inside the ball head 331 of the adjusting assembly 3, the endoscope 6 of different diameters can be clamped when inserted, and the scope of use is wide, and any angle of the endoscope 6 can be adjusted, and the position of the endoscope 6 in the endoscope sleeve 5 can be adjusted, and adaptive adjustment can be performed, and the adjustment is performed by screw rotation, and the adjustment is convenient and fast; The adjusting assembly 3 comprises: a support rod 31, an extension rod 32, an outer fixing frame 33, and a first adjusting knob 34; the support rod 31 is an L-shaped structure, the lower end of the support rod 31 is detachably mounted on the slot 21, the two ends are bent and extended toward one side of the endoscope sleeve 5, and the extension rod 32 is movably mounted inside, the rear end of the extension rod 32 is movably connected to the first adjusting knob 34, the first adjusting knob 34 is movably connected to the support rod 31 through a thread, and extends out of the rear end of the support rod 31; the front end of the extension rod 32 is fixedly mounted on the outer fixing frame 33, the inner portion of the outer fixing frame 33 is A ball head 331 is movably installed on the ball head 331, and an endoscope 6 is detachably installed on the ball head 331. A fixing knob 332 is threadedly installed on the upper end of the extension rod 32 between the outer fixing frame 33 and the ball head 331; the front and rear extension of the extension rod 32 is controlled by rotating the first adjusting knob 34 forward or reversely, and the ball head 331 is fixed to any position by fixing and loosening the fixing bolt; the adjustment movement process of the adjustment component 3 is as follows: when it is necessary to adjust the length of the extension block and thus adjust the position of the endoscope 6 in the endoscope sleeve 5, the first adjusting knob 34 is directly turned, and the first adjusting knob The rotation of 34 drives the extension rod 32 to move, thereby realizing adjustment. The extension rod 32 and the first adjusting knob 34 are in a rotationally connected relationship, and are not a sleeved rotationally connected, so as to ensure that the positive rotation of the first adjusting knob 34 drives the extension rod 32 forward, and the reverse rotation drives the extension rod 32 backward; when it is necessary to adjust and fix the angle, the fixing knob 332 is directly rotated to relax the ball head 331 to realize arbitrary rotation. After rotating to a suitable position, the fixing knob 332 is rotated to fix the ball head 331, which can actually complete the angle fixing.

[0029] Example 2

[0030] In this embodiment, based on the ball head 331 described in Example 1, the ball head 331 is a hollow structure, and a through groove 333 is provided inside the ball head 331. The through groove 333 is a structure of non-equal diameters from top to bottom, and the diameter gradually decreases from the outside to the inside of the endoscope 6. The non-equal diameter structural design can meet the structure of the endoscope 6 and realize the insertion and fixation of the endoscope 6. In addition, in this embodiment, in order to effectively protect the endoscope 6 and prevent damage to the endoscope 6 during insertion and fixation, a cushion layer 334 is provided on the inner side of the through groove 333. The endoscope 6 is protected by the provided cushion layer 334. The cushion layer 334 can be a structure of silicone or rubber, which can not only play a role of squeezing and fixing during insertion, but also increase the friction force to better form a fixing effect.

[0031] In addition, in the present embodiment, it is considered that the ball head 331 is used for fixing; the initial design is to directly sleeve the ball head 331 inside the outer fixing frame 33 for direct fixing and use, but it is found during operation that after the endoscope 6 is fixed, when the height of the outer fixing frame 33 is less than or equal to the height of the ball head 331, when the height of the endoscope 6 is rotated to adjust the height, the endoscope 6 and the fixing frame will be relatively limited, resulting in the rotation adjustment angle being limited, and the medical staff's needs for angle adjustment cannot be met to the maximum extent; therefore, in order to solve the above-mentioned problem, in the present embodiment, the height of the outer fixing frame 33 is smaller than the height of the ball head 331; in this way, when the endoscope 6 is rotated, due to the height difference between the ball head 331 and the outer fixing frame 33, the rotation angle of the endoscope 6 will be larger, which can better meet the medical staff's needs for angle adjustment;

[0032] In addition, in the present embodiment, based on the fixed block 2 described in Example 1, the fixed block 2 is an arc-shaped structure, which can better fit the outer surface of the endoscope sleeve 5 and is not easy to rotate. A friction block 22 is arranged inside the fixed block 2. The friction block 22 increases the friction force, so that the arc block will not easily slide along the endoscope sleeve 5 under the action of the gravity of the endoscope 6; at the same time, three fixed blocks 2 are arranged, which are equidistantly installed on the tightening belt 1.

[0033] Example 3

[0034] In this embodiment, based on the fixing block 2 and tightening belt 1 described in Example 1 and Example 2, the second adjusting knob 4 is installed on the tightening belt 1, and the end of the tightening belt 1 is a rack 41 structure and extends into the inside of the adjusting knob, forming a four-corner structure with the three fixing blocks 2. Specifically, the fixing blocks 2 are fixed equidistantly within a range of 180°, and finally the second adjusting knob 4 is fixed within another 180° range. At this time, the fixing block 2 and the second adjusting knob 4 will form four points. At this time, when the second adjusting knob 4 is rotated for tightening, four points can be formed to fix the endoscope sleeve 5; the second adjusting knob 4 includes an inner fixing button 40 and an outer fixing button 44, and the inner fixing button 40 and the outer fixing button 44 are fixed by bolts. The inner fixing button 40 is installed on the tightening belt 1, and an outer fixing tooth 43 is provided on the inner side wall of the inner fixing button 40, and a circular hole 42 is opened in the center of the inner portion, and the tightening belt 1 is provided on both sides of the circular hole 42. The rack 41 at the end passes through; a plurality of protrusions 49 are fixedly installed on the inner side wall of the outer fixing button 44, and a fixing column 47 is fixedly installed on the inner ground of the outer fixing button 44 between the protrusions 49; a lower disc 45 is movably installed on the inner bottom end of the outer fixing button 44, and an upper toothed disc 46 is fixedly installed on the lower disc 45; the upper toothed disc 46 and the rack 41 are installed in meshing with each other; the expansion and contraction control fixed block 2 of the tightening belt 1 is controlled by rotating the adjusting knob forward or backward to form a clamping effect on the endoscope sleeve 5; specifically, when tightening or loosening is required, the outer fixing button 44 is directly rotated, and at the same time, the outer fixing button 44 or the internal upper toothed disc 46 is driven to rotate to drive the rack 41 to move, and the movement of the rack 41 will drive the tightening belt 1 to tighten, and it will not be recovered after tightening until it is manually rotated and controlled, so that the endoscope sleeve 5 can be fixed; specifically, its principle is similar to the knob fixing method at the rear end of the helmet.

[0035] At the same time, in this embodiment, the end of the tightening belt 1 is also provided with a large protrusion 11, and the rack 41 at the end of the tightening belt 1 is retracted and placed inside the large protrusion 11 for storage, and the large protrusion 11 can also be directly extended to the fixed block 2 for fixation, so as to serve as a support (it should be noted that the tightening belt 1 is not fixedly arranged). Of course, this is just one of the ways.
