[0049] Preferably, the first driving wheel 311 is a one-way rotating gear; the second driving wheel 312 is a bevel gear.

[0052] Preferably, the driving unit 31 further includes a return spring 314. One end of the return spring 314 is connected to the fixed body 11, and the other end is connected to the driving rack 3131. The return spring 314 is used to always apply an elastic thrust to the driving rack 3131, so as to realize that when a force is applied to the driving knob 3132 to drive the driving rack 3131 to move linearly, and then the first driving wheel 311 is driven to rotate by the driving rack 3131, and the second driving wheel 312 is synchronously driven to rotate; when the force applied to the driving knob 3132 is removed, the driving rack 3131 quickly moves in the opposite direction under the elastic thrust of the return spring 314 and returns to the initial position to prepare for the next application of force to the driving knob 3132.

[0071] Another specific embodiment of the present invention provides a gold label implantation device, as Figure 7 shown, including a syringe 4, a thimble 5, a fixing seat 6 and the stabilizer provided in Embodiment 1. Compared with the prior art, the beneficial effects of the gold label implantation device provided in this embodiment are basically the same as those of the stabilizer provided in Embodiment 1, and will not be elaborated here one by one.

[0072] Preferably, the thimble 5 is fixedly connected to the fixing seat 6, the syringe 4 is sleeved on the thimble 5 and can move along the length direction of the thimble 5 on the thimble 5, and the stabilizer is fixedly connected to the fixing seat 6; during use, the syringe 4 is punctured to the tumor in the patient's body, the fixing seat 6 is fixed by the stabilizer to keep the spatial position of the fixing seat 6 unchanged, and then the syringe 4 is controlled to move away from the body (that is, the syringe 4 is retracted). Under the blocking action of the thimble 5, the gold label placed in the syringe 4 is implanted at the tumor in the patient's body; in this embodiment, by controlling the retraction of the syringe 4, the gold label can be ejected and implanted at the tumor in the patient's body. During the gold label implantation process, the gold label does not need to move, so that the gold label can be more accurately implanted at the tumor in the patient's body, accurately marking the tumor, and further improving the subsequent treatment effect.

[0073] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model.
