Description

Technical Field

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

[0002] Rigid endoscopes are endoscopic tools used in minimally invasive medical procedures. They are inserted into the body through natural cavities or small surgical incisions to guide the endoscope to the organ being examined, allowing direct image display. However, the handle of a rigid endoscope is tightly connected to the latches, focusing knob, and magnification knob, making disassembly inconvenient. For example, the existing disassembly method for the KARL STORZ H3-Z rigid endoscope typically involves clamping the handle with two clips, exposing the part to be disassembled, and then locking the disassembly baffle. Bolts are then slowly screwed into the four threaded holes below the clips, pushing the disassembly baffle upwards to remove the part. However, this method requires slowly screwing in the four bolts one by one, and cannot fully insert them all at once, requiring multiple small-amplitude repetitions, making the operation complex. To solve these problems, a rigid endoscope disassembly tool is proposed. Utility Model Content

[0003] The purpose of this invention is to solve the problem that existing rigid lens handles require four bolts to be slowly screwed in sequentially for disassembly.

[0004] The present invention adopts the following technical solution:

[0005] A medical rigid endoscope disassembly tool includes two opposing clamping plates. Each clamping plate has a through hole running vertically through it. A transmission rod is installed within the through hole. A disassembly baffle is installed at the upper end of each clamping plate. A locking groove is provided on the outer wall of each clamping plate. A connecting frame is installed within the locking groove. A lifting rod is installed below the connecting frame. A base plate is installed below the lifting rod. A tightening screw is installed on the base plate. A push plate is installed on the tightening screw. The push plate is connected to the transmission rod.

[0006] Furthermore, there is a clamping groove between the two clamping plates to limit the irregularly shaped handle body. The part of the handle body to be disassembled protrudes from the clamping groove, and the two clamping plates are fixed by screws on both sides.

[0007] Furthermore, the removal baffle is located on the upper surface of the clamping piece, the removal baffle is stuck between the part of the handle body to be removed and the clamping piece, the upper end of the transmission rod abuts against the removal baffle, each clamping piece has two through holes, and there are four transmission rods;

[0008] Furthermore, each clamping piece has a locking groove on its outer side, and the connecting frame is fitted into the locking groove. The connecting frame is U-shaped, and the two ends of the two connecting frames are connected by a locking buckle. Two lifting rods are fixedly installed below each connecting frame. The lower end of the lifting rod has a wedge-shaped limiting block, and the two sides of the base plate have wedge-shaped limiting grooves. The lifting rods and the base plate are connected by the fitting of the limiting block and the limiting groove.

[0009] Furthermore, a tightening screw is threadedly provided in the middle of the base plate, and the lower end of the tightening screw has a handle for rotating the tightening screw. The upper end of the tightening screw is connected to the push plate bearing, and the lower end of the transmission rod abuts against the push plate. The push plate has a groove for placing the transmission rod.

[0010] The beneficial effects of this utility model are:

[0011] By rotating a single tightening screw, four transmission rods can be pushed out evenly to remove the disassembly baffle. Disassembly can be completed with just one rotation, greatly reducing the operation time to one-quarter of the current time.

[0012] The four transmission rods are symmetrically distributed and engage with the lower end of the transmission rods through the groove of the push plate, ensuring that the four ejection points are subjected to the same force. This avoids deformation of the handle or damage to the parts to be disassembled due to uneven force on one side, and also eliminates the need for repeated small-amplitude operations, reducing the complexity of operation.

[0013] The connecting frame is quickly connected to the locking buckle through a U-shaped structure, and the lifting rod cooperates with the wedge-shaped limiting groove of the base plate to facilitate quick disassembly and maintenance of tools;

[0014] The clamping slots of the clamping plate can be customized according to the contours of different models of rigid lens handles, and are fixed with screws on both sides to ensure that the handle does not slip during disassembly. Attached Figure Description

[0023] Example 1

[0024] This utility model provides a medical rigid endoscope disassembly tool, including two opposing clamping plates 1. The clamping plates 1 are provided with through holes 3 extending vertically. A transmission rod 4 is provided inside the through holes 3. A disassembly baffle 5 is provided at the upper end of the clamping plates 1. A locking groove 6 is provided on the outer wall of the clamping plates 1. A connecting frame 7 is provided inside the locking groove 6. A lifting rod 9 is provided below the connecting frame 7. A base plate 11 is provided below the lifting rod 9. A tightening screw 13 is provided on the base plate 11. A push plate 15 is provided on the tightening screw 13. The push plate 15 is connected to the transmission rod 4.

[0025] Furthermore, there is a clamping groove 2 between the two clamping pieces 1, which is used to limit the irregularly shaped handle body 16. The part of the handle body 16 to be disassembled protrudes from the clamping groove 2, and the two clamping pieces 1 are fixed by screws on both sides.

[0026] Furthermore, the removal baffle 5 is located on the upper surface of the clamping piece 1. The removal baffle 5 is stuck between the part of the handle body 16 to be disassembled and the clamping piece 1. The upper end of the transmission rod 4 abuts against the removal baffle 5. Each clamping piece 1 has two through holes 3, and there are four transmission rods 4.

[0027] Furthermore, each clamping piece 1 has a locking groove 6 on its outer side, and the connecting frame 7 is fitted into the locking groove 6. The connecting frame 7 is U-shaped, and the two ends of the two connecting frames 7 are connected by a locking buckle 8. Two lifting rods 9 are fixedly installed below each connecting frame 7. The lower end of the lifting rod 9 has a wedge-shaped limiting block 10, and the two sides of the base plate 11 have wedge-shaped limiting grooves 12. The lifting rod 9 and the base plate 11 are connected by the fitting of the limiting block 10 and the limiting groove 12.

[0028] Furthermore, a tightening screw 13 is threadedly provided in the middle of the base plate 11. The lower end of the tightening screw 13 has a handle 14 for rotating the tightening screw 13. The upper end of the tightening screw 13 is connected to the bearing of the push plate 15. The lower end of the transmission rod 4 abuts against the push plate 15. The push plate 15 has a groove for placing the transmission rod 4.

[0029] Working principle:

[0030] When using the lens, disassemble the irregularly shaped H3-Z model hard lens handle. Place the irregularly shaped handle body 16 into the clamping groove 2 between the two clamping pieces 1. The inner wall of the clamping groove 2 has an anti-slip texture design, which can closely fit the outer contour of irregularly shaped handles such as KARL STORZ H3-Z, ensuring that the handle body 16 does not slip during disassembly. The parts to be disassembled, such as the clips 17, focusing knob 18, and magnification knob 19, must be fully exposed above the opening of the clamping groove 2, so that the part of the handle body 16 to be disassembled is exposed through the clamping pieces 1. Fix the two clamping pieces 1 with screws. Insert the removal baffle 5 into the upper surface of the clamping pieces 1, so that it is engaged in the gap between the part of the handle body 16 to be disassembled and the clamping pieces 1. Remove the baffle. The bottom surface of plate 5 is pressed against the clamping plate 1. Transmission rods 4 are inserted from bottom to top into the through holes 3 of the two clamping plates 1, so that the upper ends of the four transmission rods 4 abut against the removal baffle 5. Two U-shaped connecting frames 7 are embedded into the slots 6 on the outer wall of the clamping plates 1. The two connecting frames 7 are secured by the latches 8. Then, the base plate 11 is fitted with the limiting blocks 10 of the lifting rods 9 below the connecting frames 7 through the limiting grooves 12. The wedge-shaped limiting blocks 10 at the lower ends of the two lifting rods 9 below the connecting frames 7 are engaged with the sides of the base plate 11. The wedge-shaped limiting groove 12 engages to form a stable four-point support structure, preventing the base plate 11 from shifting during operation. By rotating the tightening screw 13 upwards on the base plate 11 using the handle 14, the push plate 15 on the tightening screw 13 contacts the transmission rod 4. The groove of the push plate 15 engages with the transmission rod 4, preventing the push plate 15 from shifting. At this point, the transmission rod 4 is held in place. Continuing to rotate the tightening screw 13 drives the push plate 15 vertically upwards, thereby driving the transmission rod 4 upwards to apply force to the removal baffle 5. The force applied to the handle body 16 causes the removal baffle 5 to remove the part to be removed, thus completing the disassembly of the rigid endoscope handle. The rigid endoscope can be disassembled by simply turning a screw. After the removal baffle 5 pushes the part to be removed away from the handle, the screw 13 is rotated in the opposite direction to lower the push plate 15. The transmission rod 4 is separated from the removal baffle 5. At this time, the loosened part can be taken out directly. Loosen the lock 8 and remove the connecting bracket 7 to separate the clamping piece 1 from the base plate 11 for easy cleaning and storage.

[0031] Different shaped clamping plates 1 with clamping grooves 2 can also be selected according to different models of handle body 16.
