Description

Technical Field

[0001] This utility model relates to the field of medical equipment, and in particular to a tool for disassembling flexible medical endoscopes. Background Technology

[0002] Flexible medical endoscopes, such as gastroscopes, duodenoscopes, and bronchoscopes, are commonly used precision medical instruments in clinical practice. They can be inserted into the body through cavities or minimally invasive incisions to examine and treat the gastrointestinal tract, respiratory tract, and other parts. However, these instruments are expensive, have high maintenance costs, and have delicate internal structures. After prolonged use, the CCD lens in the insertion part needs to be replaced. However, because the CCD lens is small and not centered, and is glued to the inside of the tip, it is inconvenient to remove it by hand or with a regular pin. To solve the above problems, a flexible medical endoscope disassembly tool is proposed. Utility Model Content

A transverse groove 36 is provided on the sliding frame 35, and a second adjusting screw 37 and a slider 38 are both mounted in the transverse groove 36. An adjusting rod 39 is mounted on the second support frame 31.

[0030] Furthermore, the placement frame 22 is fixedly mounted on the first support frame 21. The placement frame 22 has a semi-circular groove, and several limiting frames 24 are evenly fixedly mounted on the groove. The top of the limiting frame 24 is provided with a clamping plate 25 through a rotating shaft. The outer surface of the clamping plate 25 has an arc-shaped recess for cooperating with the outer wall of the soft lens 5. The clamping plate 25 has an anti-slip pad.

[0031] Furthermore, a fixing strap 23 is provided at one end of the placement frame 22 via a pivot. The fixing strap 23 is made of soft, inelastic material. Several limiting frames 24 are evenly fixed on the inner side of the fixing strap 23. The limiting frames 24 have clamping plates 25 for clamping the soft mirror 5.

[0032] Furthermore, the clamping frame 26 is located at the other end of the placement frame 22. The clamping frame 26 is provided with two guide wheels 27 connected by bearings. The end of the fixing strap 23 passes through the two guide wheels 27 and is located below the folding plate 28. One side of the folding plate 28 is mounted on the clamping frame 26 via a pivot, and the other side is connected to the clamping frame 26 via a tightening bolt 29 for clamping the end of the fixing strap 23.

[0033] Furthermore, the two sides of the movable frame 33 are connected to the guide frame 32 to make the movable frame 33 parallel to the first support frame 21 and the second support frame 31. The side of the movable frame 33 closest to the second support frame 31 is provided with an adjusting rod 39 through a bearing. The adjusting rod 39 is threadedly connected to the second support frame 31 to drive the movable frame 33 to move back and forth.

[0034] Furthermore, the upper end of the movable frame 33 is provided with a first adjusting screw 34 on each side via bearings. The sliding frame 35 is threaded onto the first adjusting screw 34 to control the up and down movement of the sliding frame 35. The transverse groove 36 is located in the middle of the sliding frame 35. One end of the second adjusting screw 37 is connected to the transverse groove 36 via bearings, and the other end extends out of the transverse groove 36 and is located on the outside of the sliding frame 35.

[0035] Furthermore, the slider 38 is threaded with a push pin 4, which faces the flexible lens 5 and is used to push out the lens 6 of the flexible lens 5.

[0036] Working principle:

[0037] In use, the tip of the flexible medical endoscope 5 is placed in the semi-circular groove of the placement frame 22. The clamping plate 25 of the limiting frame 24 inside the placement frame 22 can rotate around the limiting frame 24 to fit the flexible endoscope 5. Since the outer side of the clamping plate 25 has an arc-shaped concave shape and an anti-slip pad, it can fit well with the outer wall of the flexible endoscope 5, increasing friction and preventing the flexible endoscope 5 from sliding. Then, the fixing strap 23 is pulled closer and wrapped around the placement frame 22 and placed on the flexible endoscope 5. The limiting frame 24 and the clamping plate 25 on the inner side of the fixing strap 23 further clamp the flexible endoscope 5. The end of the fixing strap 23 is passed through the two guide wheels 27 on the clamping frame 26. The guide wheels 27 make it easy to apply force to the fixing strap 23 and also make it easy to clamp the fixing strap 23. The fixing strap 23 is inserted under the folding plate 28. The folding plate 28 is connected to the clamping frame 26 by tightening the bolt 29, thereby clamping the end of the fixing strap 23 and completing the firm clamping of the flexible endoscope 5.

[0038] Rotating the first adjusting screw 34 causes the sliding bracket 35 to move up and down along the first adjusting screw 34 due to the threaded connection of the first adjusting screw 34, thereby adjusting the up and down position of the ejector pin 4. Rotating the second adjusting screw 37 causes the slider 38 to move left and right within the transverse groove 36 due to the threaded connection of the slider 38, thereby moving the ejector pin 4 left and right. By rotating the first adjusting screw 34 and the second adjusting screw 37, the ejector pin 4 and the lens 6 of the flexible lens 5 are aligned. Rotating the adjusting rod 39 causes the moving bracket 33 to move along the guide bracket 32 ​​toward the lens 6, thereby causing the ejector pin 4 to gradually approach and push the lens 6. Since the lens 6 is glued to the inside of the tip, it can be pushed out from the tip by the force of the ejector pin 4. The CCD lens 6 can then be removed by hand, completing the disassembly operation.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. The various components mentioned in this utility model are common technologies in the existing field. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
