Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to a water-flushing aspiration ablation device. Background Art

[0002] During surgery, continuous flushing is required to keep the surgical field clear, and blood needs to be sucked out of the surgical field. This is especially necessary during ablation and hemostasis. Traditionally, flushing balls, aspirators, ablation devices, and other instruments are used together, or multiple functional devices are integrated into one device. However, the functions of existing integrated devices are usually simply superimposed, and there is a lack of linkage between the devices, resulting in complex operations, large equipment size, and low efficiency. Flushing and sucking blood clots and tissue residues from surgical instruments can easily block the tube.

[0003] Therefore, it is necessary to provide a water suction ablation device that can prevent tube blockage and water leakage, and can effectively solve the problem of low efficiency of existing integrated equipment and easy blockage of tubes by blood clots and tissue residues caused by water suction surgical instruments. Summary of the invention

A water suction pipe and a water flushing pipe are arranged at the middle part at the opposite side of the lower tube. The outer water suction pipe or the water flushing pipe and the lower tube at the lower end of the middle part form a three-way structure. A rotary valve is arranged in the middle of the body.

[0007] The rotary valve has a cylindrical outer shell, the shape of which is adapted to the round pancake-shaped hollow cavity in the middle part, and is inserted into the middle part. A three-way pipe is installed inside the rotary valve to form a three-way structure with the suction pipe, flushing pipe or down pipe of the body. A paddle is provided on one end surface of the rotary valve, and the paddle is turned to switch different through holes inside the rotary valve to communicate with the three-way structure.

[0008] The operating tube is a round tube inserted into the lower tube.

[0009] Furthermore, the bottom end of the middle part is a closed end, the outer surface of the closed end is provided with a clamping concave platform, two spherical grooves are symmetrically distributed inside the clamping concave platform, and the top end of the middle part is an open end, and the rotary valve is embedded and installed;

[0010] A spring piece is installed at the bottom of the middle part, and the spring piece includes a circular installation ring and a conical front section. The installation ring and the conical front section are integrally cast. A spherical boss is provided at a position of the conical front section near the bottom side of the middle part, and the spherical boss is adapted to the spherical groove.

[0011] Furthermore, a circular hole is formed through the center of the closed end of the middle portion, a stud is provided at the bottom end of the rotary valve, a nut is provided under the rotary valve, and a mounting hole is formed through the center of the mounting ring. The stud passes through the circular hole and the mounting hole in turn and is fixed with the nut through threaded cooperation.

[0012] Furthermore, the stud is cut at right angles to form a trimmed stud, and the mounting hole is cut at straight edges to form a trimmed mounting hole, and the right angles of the trimmed stud are fitted with the straight edges of the trimmed mounting hole.

[0013] Furthermore, a sealing ring structure is provided on the contact surface between the operating tube and the lower tube.

[0014] Furthermore, the shape of the paddle on the end face of the rotary valve conforms to ergonomics and is configured to be a boat shape, a fallen leaf shape, or a finger sleeve shape.

[0015] Furthermore, the monopolar ablation device includes a monopole and a monopolar switch, the monopolar switch is electrically connected to the monopole, the monopole is integrated at the end of the operating tube, and the monopolar switch is located on one side of the water suction tube in the middle part.

[0016] Furthermore, an electric conductor is arranged inside the operating tube, one end of the electric conductor is electrically connected to the single pole, and the other end of the electric conductor passes through the operating tube, the lower tube and the middle part and is electrically connected to the single pole switch.

[0017] Furthermore, the operating tube is a component made of medical insulating plastic or plastic material.

[0018] The advantages of the present invention compared with the prior art are:

[0019] 1. Through the overall structure designed by the present application, compared with the simple superposition of the knowledge between the functions of the existing integrated equipment, the present application not only realizes disassembly, flushing and dredging conveniently through the threaded matching, but also the attraction force and flushing force can be adjusted steplessly, which can prevent pipe blockage and water leakage.
