Description

Technical Field

[0001] The invention relates to the technical field of choledochoscopes, in particular to a durable choledochoscope water inlet joint. Background Art

[0002] During gallbladder surgery, the gallbladder cavity needs to be injected with water to expand the gallbladder cavity to an appropriate degree to increase the operating space, which in turn helps provide a clear field of view for the surgery and facilitates the completion of various operations.

[0003] Before the existing choledochoscope is injected with water, it is necessary to connect the water injection pipe to the water injection joint. The connection between the existing choledochoscope water pipe and the water injection joint is usually in the form of a threaded connection. The threaded connection requires the addition of a sealing gasket inside the joint to ensure the sealing of the joint. However, in actual use, since the water injection pipe and the water injection joint often need to be disassembled and connected, the operator is required to accurately align the threads during use, otherwise the thread engagement will be offset, which may easily cause the threads to shear against each other, resulting in gaps and wear, and the rotating inserted water inlet pipe will exert a rotating extrusion force on the sealing gasket, which may easily cause shear damage to the sealing gasket, thereby resulting in insufficient sealing, water leakage from the water injection joint, and low durability. Summary of the invention

[0004] In view of the problems in the prior art, the present invention provides a durable water inlet connector for a choledochoscope.

[0005] The technical solution adopted by the present invention to solve the technical problem is: a durable choledochoscope water inlet joint, comprising an adjustment seat, a water inlet pipe is fixedly connected to one side of the adjustment seat, a first thread is provided on one side of the water inlet pipe, a placement groove is provided on the end of the water inlet pipe away from the adjustment seat, a transmission groove is provided on the side of the water inlet pipe close to the placement groove, a limiting groove is provided on the water inlet pipe corresponding to the transmission groove array, a regulator is provided at the middle position of the water inlet pipe, a second thread is provided on the inner wall of the regulator, the first thread and the second thread are provided correspondingly, and the regulator and the water inlet pipe thread Connection, one end of the regulator is fixedly connected to a limiting ring, and a plurality of extrusion plates are provided at the end of the limiting ring away from the regulator, and extrusion grooves are provided on the extrusion plates, and a transmission shaft is slidably connected in the extrusion grooves, and both ends of the transmission shaft are fixedly connected to limiting blocks, and a transmission rod is fixedly connected at the middle position of the transmission shaft, and the transmission rod is slidably connected to the limiting groove, and a clamping plate is fixedly connected to the bottom end of the transmission rod, and the clamping plate is movably connected to the transmission groove, a sealing spring pad is provided in the placement groove, and a water inlet pipe is provided on one side of the sealing spring pad, and the water inlet pipe is slidably connected to the water inlet connecting pipe.

[0006] Specifically, a stop valve is fixedly installed on the top end of the adjusting seat, an adjusting button is fixedly installed on the bottom end of the adjusting seat, and a water outlet pipe is fixedly installed on the side of the adjusting seat away from the water inlet pipe.

[0007] Specifically, the extrusion groove is designed as an inclined structure, and a fixing groove is provided at one end of the extrusion plate close to the limiting ring.

[0008] Specifically, the fixing groove is designed as a T-shaped structure, the cross section of the limiting ring is designed as a T-shaped structure, and the limiting ring is slidably connected to the fixing groove.

[0009] Specifically, the sealing spring washer is designed as an annular structure, and a shrinkage groove is provided on the surface of the sealing spring washer.

[0010] Specifically, a groove is provided at one end of the water inlet pipe close to the sealing spring washer, and the groove is designed as an annular structure.

[0012] Specifically, the surface of the regulator is provided with anti-skid grooves, and both ends of the anti-skid grooves are at a certain distance from the edge of the regulator.

[0013] Beneficial effects of the present invention: The present invention adopts the structural design of external threads and the design of a pipe in which the regulator is sleeved on the surface of the water inlet pipe. It is only necessary to insert the water inlet pipe into the water inlet pipe and to pull the water inlet pipe by rotating the regulator, thereby avoiding the operator's threaded connection of the water injection pipe, which may easily cause the thread engagement to shift and cause mutual shearing and wear of the threads. In addition, the water inlet pipe is pulled by the rotating regulator, so that the pulled water inlet pipe applies horizontal pressure to the sealing spring gasket, making the extrusion force uniform and stable, ensuring the sealing performance while avoiding the sealing spring gasket from being damaged by the extrusion force, thereby improving durability.

[0019] Specifically, a stop valve 18 is fixedly installed on the top of the adjusting seat 1, an adjusting button 19 is fixedly installed on the bottom of the adjusting seat 1, and a water outlet pipe 20 is fixedly installed on the side of the adjusting seat 1 away from the water inlet pipe 2, so as to facilitate the limitation and use of water flow.

[0020] Specifically, the extrusion groove 11 is designed as an inclined structure, and a fixed groove 21 is provided at one end of the extrusion plate 10 close to the limiting ring 9, so that the extrusion groove 11 can extrude the transmission shaft 12. The fixed groove 21 is designed as a T-shaped structure, and the cross-section of the limiting ring 9 is designed as a T-shaped structure. The limiting ring 9 is slidably connected with the fixed groove 21, so that the limiting ring 9 can pull the extrusion groove 11 through the fixed groove 21.

[0021] Specifically, the sealing spring gasket 16 is designed as an annular structure, and a contraction groove 23 is opened on the surface of the sealing spring gasket 16 to facilitate water flow and enhance the sealing performance of the sealing spring gasket 16.

[0022] Specifically, a slot 22 is provided at one end of the water inlet pipe 17 close to the sealing spring gasket 16 . The slot 22 is designed as a ring structure, and the clamping plate 15 is designed as an arc structure.

[0024] When in use, insert the water inlet pipe 17 into the water inlet pipe 2. When the water inlet pipe 17 fits with the sealing spring gasket 16, rotate the regulator 7. Since the first regulator 7 is threadedly connected to the water inlet pipe 2, the regulator 7 rotates and moves along the water inlet pipe 2 toward the adjustment seat 1. The rotating adjustment seat 1 drives the limit ring 9 to move. The moving limit ring 9 pulls the extrusion plate 10 through the fixed groove 21. The extrusion plate 10 moves horizontally toward the adjustment seat 1. The moving extrusion plate 10 applies an extrusion force to the transmission shaft 12 through the top of the extrusion groove 11. The extruded transmission shaft 12 drives the transmission rod 14 to move. The moving transmission rod 14 drives the clamping plate 15 to move toward the center of the water inlet pipe 17. When the transmission shaft 12 is located at the tail end of the extrusion groove 11, the clamping plate 15 is meshed with the clamping groove 22 provided in the water inlet pipe 17. At this time, the placement groove 4 loses its limiting effect on the clamping plate 15, and the rotating regulator 7 continues to pull the extrusion plate 10. The pulled extrusion plate 10 pulls the transmission shaft 12, and the pulled transmission shaft 12 pulls the transmission rod 14. The pulled transmission rod 14 pulls the clamping plate 15. The pulled clamping plate 15 pulls the water inlet pipe 17 through the clamping groove 22. The pulled water inlet pipe 17 moves toward the direction of the sealing spring gasket 16. The moving water inlet pipe 17 squeezes the sealing spring gasket 16 with horizontal force, so the sealing performance is better and the wear and tear in daily use is lower.
