Description

Technical Field

[0001] This utility model relates to an ablation electrode, specifically a hand-controlled surgical electrode. Background Technology

[0002] The ablation electrode uses a medical high-frequency generator to generate energy, which, together with a neutral electrode, forms an energy circuit for electrocautery and coagulation of the wound during surgery. The power control switch for the hand-operated electrode is located on the handle. Smoke is generated during the electrocautery and coagulation process, and this smoke needs to be removed to facilitate the smooth progress of the surgery.

[0003] The patent document with patent publication number CN209713125U describes a manual ablation electrode with an internal cavity smoke extraction mechanism. The electrode includes a shell, a circuit board disposed within the shell, an electrocoagulation button and an electrocautery button disposed on the shell and electrically connected to the circuit board, a plug connected to the rear end of the shell and electrically connected to the circuit board, and an electrode head disposed at the front end of the shell and electrically connected to the circuit board. It also includes a suction tube connected to the rear end of the shell. An internal cavity smoke extraction channel is formed within the shell, extending along the length of the shell. The front end of the internal cavity smoke extraction channel extends to the front end of the shell to form an internal cavity smoke extraction hole, and the rear end of the internal cavity smoke extraction channel extends to the rear end of the shell and communicates with the suction tube. While having an internal cavity smoke extraction function, it retains the original structural dimensions of the electrode head. The structure is simple, lightweight, and facilitates the smooth operation of the surgery.

[0004] However, the existing technology has the following drawbacks: the device cannot adjust the length of the electrode according to the depth of the surgical site, and the shadow at the electrode head will obstruct the doctor's view, making it inconvenient for the doctor to use. Utility Model Content

[0005] The purpose of this invention is to provide a hand-controlled surgical electrode to solve the problem that existing hand-controlled electrodes cannot adapt to surgeries at different depths.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A hand-controlled surgical electrode includes a handle, a circuit board disposed within the handle, and a hand control button disposed on the handle and electrically connected to the circuit board. The rear end of the handle is provided with a suction tube connector, and the front end of the handle is movably inserted into a functional tube. The functional tube is provided with a smoke-smoking through hole. One end of the functional tube is fixedly connected to an electrode head, and the other end of the functional tube is connected to the suction tube connector through a connecting unit. The front end of the handle is provided with an illumination module near the functional tube, and the side of the handle is provided with a telescopic mechanism.

[0008] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0009] In one alternative embodiment: the telescopic mechanism includes a push key, which is rotatably connected to a connecting block at the upper end of the slide plate. One end of the push key is fixedly connected to a limiting groove 1. The upper end of the slide plate is provided with a limiting groove 2 corresponding to the limiting groove 1. A spring is fixedly connected between the limiting groove 1 and the limiting groove 2. The slide plate is slidably connected to a corresponding slide groove on the handle. Limiting teeth are fixedly connected around the slide groove. The end of the push key away from the limiting groove 1 is fixedly connected to a limiting plate. The limiting plate is engaged with the limiting teeth. The lower end of the slide plate is fixedly connected to a functional tube.

[0010] In one alternative: the connecting unit includes a telescopic hose, one end of which is fixedly connected to a suction tube connector, and the other end of which is fixedly connected to a smoking through hole.

[0011] In one alternative embodiment: the lighting module includes a light and a light button, the light being fixedly connected to the front end of the handle near the function tube, the light button being located at the outer end of the handle, and both the light and the light button being electrically connected to the circuit board.

[0012] In one alternative: one end of a cable is fixedly connected to the rear end of the handle, the other end of the cable is fixedly connected to a cable plug, and the cable is electrically connected to a circuit board.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] In one embodiment, such as Figures 1-4 As shown, a hand-controlled surgical electrode includes a handle 700, a circuit board 701 disposed within the handle 700, and hand control buttons 400 disposed on the handle 700 and electrically connected to the circuit board 701. The handle 700 has a suction tube connector 600 at its rear end and a functional tube 300 movably inserted at its front end. The functional tube 300 has a smoke-absorbing hole 301. One end of the functional tube 300 is fixedly connected to an electrode head 100, and the other end of the functional tube 300 is connected to the suction tube connector 600 via a connecting unit. An illumination module is located near the functional tube 300 at the front end of the handle 700. A telescopic mechanism is located on the side of the handle 700. The electrode head 100 performs electrocautery and electrocoagulation on the wound during surgery. The hand control buttons 400 are on the handle and control the electrode's operation via the circuit board 701. The smoke-absorbing hole 301 in the functional tube 300 removes smoke generated during surgery. Through the cooperation of the telescopic mechanism and the connecting unit, the control function tube 300 extends from the handle to achieve the purpose of lengthening and shortening, which can adapt to surgery of different depths.

One end of the push key 501 is fixedly connected to a limiting groove 504. The upper end of the slide plate 502 is provided with a limiting groove 505 corresponding to the limiting groove 504. A spring 506 is fixedly connected between the limiting groove 504 and the limiting groove 505. The slide plate 502 is slidably connected in a corresponding sliding groove 507 on the handle 700. Limiting teeth 508 are fixedly connected around the sliding groove 507. The end of the push key 501 away from the limiting groove 504 is fixedly connected to a limiting plate 509.

The limiting plate 509 and the limiting tooth 508 are connected to fix the functional tube 300. When the functional tube 300 needs to be extended or retracted, the front end of the push button 501 is pressed, compressing the spring 506. The limiting plate 509 fixed at the rear end of the push button 501 disengages from the limiting tooth 508, pushing the push button 501 to drive the slide plate 502 to slide along the slide groove 507. The slide plate 502 drives the functional tube 300 to extend or retract. When the front end of the push button 501 is released, the spring 506 rebounds, the push button 501 resets, and the limiting plate 509 is engaged in the limiting tooth 508 to fix the functional tube 300.

[0025] In one embodiment, such as Figure 2 As shown, the connection unit includes a telescopic hose 601. One end of the telescopic hose 601 is fixedly connected to the suction tube connector 600, and the other end of the suction tube connector 600 is fixedly connected to the smoking through hole 301. When the functional tube 300 extends, the telescopic hose 601 extends, ensuring that the functional tube 300 and the suction tube connector 600 are always connected.

The cable 801 is electrically connected to the circuit board 701, and the hand-controlled surgical electrode is powered through the cable 801 and the cable plug 802.

[0028] In one embodiment, such as Figure 2As shown, the functional tube 300 is covered with an insulating sleeve 200 to ensure the insulation of the device and prevent leakage.

[0029] In one embodiment, such as Figure 1 As shown, the handle 700 is a plastic handle shell, which has low manufacturing cost, is lightweight, durable and has good insulation properties.
