[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] An otological surgical electrode includes a handle 1, a steel tube 5 rotatably connected inside the handle 1, a mounting block 6 fixedly connected inside one end of the steel tube 5, a rotating ring 7 fixedly connected to the outside of the mounting block 6, the rotating ring 7 being fixedly connected to the steel tube 5, a water inlet pipe 11 being provided inside the steel tube 5, a water outlet groove 12 being formed on the side wall of the steel tube 5, the water outlet groove 12 being fixedly connected to the water inlet pipe 11, an annular groove 13 being formed inside the steel tube 5, a plurality of annularly distributed water inlet holes 14 being formed inside the steel tube 5, the plurality of water inlet holes 14 being respectively connected to the annular groove 13, a bent pipe 15 being fixedly connected inside the steel tube 5, and a water outlet pipe 16 being fixedly connected to the lower end of the bent pipe 15.

[0025] For example, one end of the inlet pipe 11 is equipped with a water supply device. The inlet pipe 11 transports saline solution into the device and injects the saline solution into the surgical site through the outlet groove 12 to rinse the blood produced during the surgery, making it easier to observe the condition of the surgical site. One end of the outlet pipe 16 is equipped with a water pumping device. The water pumping device removes the air inside the outlet pipe 16 and extracts the saline solution from the ear canal through the ring groove 13 and the inlet hole 14. Multiple water pumping holes facilitate the extraction of saline solution.

[0026] An anti-slip sleeve 2 is fixedly connected to the outside of the handle 1.

[0027] For example, the anti-slip sleeve 2 helps the operator to hold the handle 1 firmly, preventing the handle 1 from sliding during use and affecting the stability of the operation.

[0028] The handle 1 has an internal thread 3 inside, and a threaded ring 4 is connected to the outer thread of the internal thread 3.

[0029] For example, the internal thread 3 facilitates the movement of the threaded ring 4 inside the handle 1.

[0030] The threaded ring 4 contacts the inside of the handle 1, and the threaded ring 4 is fixedly connected to the steel pipe 5.

[0031] For example, the threaded ring 4 is installed on the steel pipe 5.

[0032] A ceramic head 8 is fixedly connected to the side wall of the mounting block 6, and a cutting blade 9 is provided on one side of the ceramic head 8.

[0033] For example, the cutting blade 9 cuts the skin flap, and the ceramic head 8 is used to separate the skin flap.

[0034] A connecting wire 10 is fixedly connected to the outside of the cutting blade 9, and the connecting wire 10 is fixedly connected to the ceramic head 8.

[0035] For example, after connecting the 10-wire plasma surgical device, stepping on the cutting pedal of the plasma surgical device will cause the cutting blade 9 to output cutting energy and cut the skin flap. Because the cutting blade 9 has a small diameter, the energy is concentrated and the thermal damage to the skin flap is small. When bleeding occurs, stepping on the coagulation pedal of the plasma surgical device will cause the cutting blade 9 to output coagulation energy and coagulate the area that needs coagulation.

[0036] The positive terminal of the connecting wire 10 is connected to one end of the cutting disc 9, and the negative terminal of the connecting wire 10 is fixedly connected to the steel pipe 5.

[0037] For example, the outer steel tube assembly and the connecting wire 10 are connected by the handle 1 to form a complete electrode.

[0038] Working principle: When this utility model is used, the rotating ring 7 is rotated, which drives the steel pipe 5 to rotate. The steel pipe 5 drives the threaded ring 4 to rotate. The threaded ring 4 and the internal thread 3 have a threaded movement, which controls the extension and retraction of the steel pipe 5 inside the handle 1. This makes it easy to adjust the length of the device and make the device suitable for different patients. The anti-slip sleeve 2 is used to operate the handle 1.

[0039] Handle 1 connects the outer steel tube assembly and connecting wire 10 to form a complete electrode. After connecting wire 10 is connected to the plasma surgical device, stepping on the cutting pedal of the plasma surgical device will cause the cutting blade 9 to output cutting energy and cut the skin flap. Because the cutting blade 9 has a small diameter and concentrated energy, the skin flap is less thermally damaged. When bleeding occurs, stepping on the coagulation pedal of the plasma surgical device will cause the cutting blade 9 to output coagulation energy and coagulate the area that needs coagulation. The cutting blade 9 cuts the skin flap and the ceramic head 8 is used to complete the separation of the skin flap.

[0040] A water supply device is provided at one end of the inlet pipe 11. The inlet pipe 11 transports saline solution into the device and injects it into the surgical site through the outlet groove 12 to rinse away the blood produced during the operation and facilitate observation of the surgical site. A water pumping device is provided at one end of the outlet pipe 16. The water pumping device removes the air inside the outlet pipe 16 and extracts the saline solution from the ear canal through the ring groove 13 and the inlet hole 14. Multiple water pumping holes facilitate the extraction of saline solution.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
