Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a double-section bendable and telescopic dissector, which can solve the above-mentioned problems in the prior art.

[0004] The present invention is achieved through the following technical solutions: a double-section bendable and telescopic dissector of the present invention comprises a handle, a telescopic and bendable insulating rod assembly is arranged in the handle, an electric hook head is arranged at the end of the insulating rod assembly, the insulating rod assembly is locked by a knob assembly at the end of the handle, a circuit board assembly is arranged in the handle, the insulating rod assembly, the electric hook head and the circuit board assembly are electrically connected through a conductive assembly, the insulating rod assembly comprises a flexible insulating tube, a spring is arranged in the flexible insulating tube, an electric hook head connecting rod is arranged in the spring, a conductive sleeve is arranged in the handle, and the flexible tube structure composed of the flexible insulating tube, the spring and the electric hook head connecting rod telescopes and slides in the conductive sleeve.

[0005] According to a further technical solution, a rubber damping ring is arranged in the handle, and the rubber damping ring is arranged at the top end position of the conductive sleeve. The flexible tube structure composed of the flexible insulating tube, the spring and the electric hook head connecting rod slides through the rubber damping ring and the handle.

[0006] According to a further technical solution, the electric hook head comprises a hook head, a bending portion of the hook head is provided on one side of the hook head, the bottom of the hook head is fixedly connected to the electric hook head connecting rod, and the flexible insulating tube is wrapped around the outer surface of the hook head and fixed by integral welding.

[0007] According to a further technical solution, an insulating layer is provided on the outer surface of the bent portion of the electric hook head.

[0008] According to a further technical solution, the knob assembly includes a thread disposed at the end of the handle, a plurality of clamping plates are disposed on one side of the thread, and also includes a thread buckle, which passes through the clamping plate and is threadably connected with the thread.

[0009] According to a further technical solution, the circuit board assembly includes a circuit board, a connector is provided on one side of the circuit board, and the connector is electrically connected to the conductive sleeve.

[0010] A further technical solution is that the conductive component includes an electric hook drum spring, which is slidably arranged in the conductive sleeve, and the electric hook drum spring is also electrically connected to the inner wall of the conductive sleeve. An electric hook screw head is arranged on the top of the electric hook drum spring, and the electric hook screw head is fixedly connected to the electric hook head connecting rod.

[0011] According to a further technical solution, the electric hook drum spring is an expansion structure formed by a plurality of arc-shaped rib plates connected to circular rings at the upper and lower ends.

[0012] A further technical solution is that an electric hook screw is arranged inside the electric hook drum spring, an electric hook nut is arranged at the bottom of the electric hook screw in threaded cooperation, the top of the electric hook drum spring is connected and fixed to the electric hook screw head, and the spring is sleeved on the outer surface of the electric hook screw head and the electric hook head connecting rod.

[0013] According to a further technical solution, the electric hook head connecting rod is fixedly connected to the hook head.

[0014] The beneficial effects of the present invention are: 1. A spring is arranged in the flexible insulating tube, and an electric hook head connecting rod is inserted into the spring, and the electric hook head connecting rod is electrically connected to the electric hook head and the sleeve assembly, so that after the flexible insulating tube wraps the spring, the flexible insulating tube can be bent by hand. Compared with the prior art, the addition of the spring also produces an unexpected technical effect, that is, when the flexible structure composed of the flexible insulating tube, the electric hook head connecting rod and the spring is bent at a faster speed, the flexible structure has supporting force and is fixed, and the flexible structure can be bent slowly with a small force. This function is just needed during surgery: when pulling, it is an excited rapid force, which is easy to keep the angle of the dissector basically fixed, and when bending is required, it is bent slowly without too much resistance, and the surgical angle requirements are easy to meet.

[0015] 2. The electric hook head includes a hook head, a bending part of the electric hook head and an insulating layer. It adopts a smaller size design. If fine adjustment is required, the bending part of the front end of the electric hook head can also assist in adjusting a small angle. Combined with the flexible structure composed of a flexible insulating tube, an electric hook head connecting rod and a spring, the double-stage bendable adjustment function is realized.

[0016] 3. The insulating head and insulating rod of a traditional dissector are connected with glue. During long-term and extensive use, the combined part is stimulated for a long time and there is a risk of breakdown, which may cause accidental injury to tissues. In this patent, a flexible insulating tube is used to completely cover the outer surface of the hook head and fix it. There is no obvious partition or connection in the middle, so it is not easy to seep water and will not cause breakdown when the internal environment is humid.

[0017] Fourth, the electric hook head of the prior art dissector is made of plastic or ceramic material. Plastic is easy to melt at an excitation temperature of 200°C, while ceramic is easy to burst under the accumulation of heat under long-term high-temperature excitation, which is very dangerous during surgery and easily causes damage to surrounding tissues. The insulation layer of this patent uses an insulating wrapping material, and the multi-layer setting of the insulation layer is not easy to burn and melt, and will not melt or burst during long-term excitation.

[0018] 5. The structural design of the electric hook nut, the electric hook screw, the electric hook screw head and the electric hook drum spring facilitates the detachable connection between the electric hook nut and the electric hook screw, so that the electric hook drum spring is limited to the outside of the electric hook screw, and the arc structure of the electric hook drum spring is utilized to elastically connect with the inside of the conductive sleeve to realize the conductive effect after sliding.

[0019] 6. First, the hook head, electric hook head connecting rod, electric hook screw head and spring are formed into an integrated welded structure, and then a flexible insulating tube is installed and fixed by hot melting. It can play a good insulation and waterproof function, and can be telescopically moved in the conductive casing, which is convenient for personnel to adjust the size.

[0020] 7. By rotating the threaded buckle, the clamping plate and the flexible insulating tube are disengaged, so that the flexible insulating tube, the hook head, the electric hook head connecting rod, the electric hook screw head and the spring can be extended and retracted. After the extension and retraction is completed, the threaded buckle is connected with the threaded thread, so that the clamping plate can clamp the flexible insulating tube, and the working length can be retracted and controlled, covering a wide length range to meet a variety of different surgical needs.

[0021] 8. By providing a conductive component, the insulating rod component and the electric hook head can maintain good electrical connection even after telescopic sliding. BRIEF DESCRIPTION OF THE DRAWINGS
