[0020] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.
[0021] like Figure 1 to Figure 4 As shown, Example 1, a microwave ablation device with nerve detection and early warning, includes a needle rod 1 and a handle 2, the needle rod 1 is connected to the lower end of the handle 2; the needle rod 1 is provided with an ablation needle 3 and a nerve detection probe 4, the ablation needle 3 is connected to the lower end of the needle rod 1, the nerve detection probe 4 is arranged at the lower end of the ablation needle 3, and the ablation needle 3 and the nerve detection probe 4 are insulated and sealed; the upper end of the handle 2 is provided with a socket 221, the ablation needle 3 and the nerve detection probe 4 are electrically connected to the microwave ablation instrument and the nerve detector through the socket 221 and the wire 6 respectively.
[0022] By integrating the nerve detection probe 4 into the front end of the ablation needle 3, the doctor can detect whether there are nerves at the microwave ablation site before microwave ablation, thereby avoiding damage to the nerve tissue. This greatly reduces the surgical risk and improves the success rate of the operation and the safety of the patient. The nerve detection probe 4 and the ablation needle 3 are integrated into one design, so that the nerve detection probe 4 and the ablation needle 3 can be introduced into the ablation site at one time to complete the two steps of detection and ablation, simplifying the surgical process, reducing the patient's pain, and reducing the time for replacing and debugging instruments during the operation, so that the doctor can complete the operation more quickly, which not only improves the surgical efficiency but also reduces the surgical cost.
[0023] Embodiment 2: This embodiment is a further improvement on the basis of embodiment 1, and its details are as follows:
[0024] The needle rod 1 includes a needle tube 11 and a choke ring 12. The needle tube 11 is provided with a coaxial cable 13 and a detection wire 14 which are electrically connected to the ablation needle 3 and the nerve detection probe 4 respectively. The coaxial cable 13 and the detection wire 14 are electrically connected to the socket 221 in a detachable manner respectively.
[0025] The ablation needle 3 is sealed and inserted into the lower end of the needle tube 11 . An antenna 31 is arranged inside the ablation needle 3 . The inner conductor of the coaxial cable 13 extends into the antenna 31 . The choke ring 12 is arranged in the needle tube 11 and contacts the upper end of the ablation needle 3 .
[0026] Embodiment 3, this embodiment is a further improvement on the basis of embodiment 2, and its details are as follows:
[0027] The handle 2 includes a grip 21 and a knob 22, the knob 22 is rotatably connected to the upper end of the grip 21, the socket 221 is arranged at the upper end of the knob 22, the lower end surface of the knob 22 is provided with a spring probe 222 electrically connected to the socket 221, the upper end surface of the grip 21 is provided with two spherical grooves 211, the inner walls of the spherical grooves 211 are respectively provided with hemispherical conductive sheets, the coaxial cable 13 and the detection wire 14 are respectively electrically connected to the two conductive sheets, and the spring probe 222 is respectively electrically connected to the conductive sheets in the two spherical grooves 211 through the rotation of the knob 22.
[0028] The spring probe 222 is electrically connected to the conductive sheets in the two spherical grooves 211 respectively, so as to realize the opening of nerve detection and microwave ablation respectively; the rapid switching between nerve detection and microwave ablation can be realized by adjusting the knob 22. The setting of the knob 22 makes it possible for nerve detection and microwave ablation to run separately, so as to avoid mutual interference between the simultaneous operation of nerve detection and microwave ablation.
[0029] Embodiment 4: This embodiment is a further improvement on the basis of embodiment 3, and its details are as follows:
[0030] The upper end surface of the handle 21 is provided with an arc-shaped guide groove 212, and two spherical grooves 211 are respectively provided at both ends of the arc-shaped guide groove 212, and the depth of the arc-shaped guide groove 212 is less than the depth of the spherical groove 211.

[0031] Embodiment 5, this embodiment is a further improvement on the basis of embodiment 4, and its details are as follows:
[0032] A spherical groove 211 is also provided in the middle of the arc-shaped guide groove 212. Since the spherical groove 211 in the middle of the arc-shaped guide groove 212 is not connected to the circuit, when the knob 22 is used to rotate the spring probe 222 into the spherical groove 211, both nerve detection and microwave ablation are turned off to avoid accidental touch of the knob 22, which may cause nerve detection or microwave ablation to be turned on.
[0033] Embodiment 6: This embodiment is a further improvement on the basis of embodiment 1, and its details are as follows:
[0034] The lower end surface of the ablation needle 3 and the outer surface of the nerve detection probe 4 form a hemispherical surface, and the area of the outer surface of the nerve detection probe 4 is less than 0.3 times the area of the hemispherical surface. The front end of the nerve detection probe 4 is an arc surface, which increases the contact surface with the nerve tissue, ensures the accuracy of nerve detection, and avoids damaging the nerve tissue; the area of the outer surface of the nerve detection probe 4 is less than 0.3 times the area of the entire hemispherical surface, which prevents the nerve detection probe 4 from affecting the contact between the lower end surface of the ablation needle 3 and the tissue to be ablated during microwave ablation.
[0035] Embodiment 7, this embodiment is a further improvement on the basis of embodiment 5, and its details are as follows:
[0036] The lower end of the ablation needle 3 is plugged with a T-shaped insulator 5, which is penetrated in the middle, and the nerve detection probe 4 is connected to the end of the T-shaped insulator 5 away from the ablation needle 3.
