[0015] Preferably, the outer wall of the puncture needle is fixedly connected to one end of the spring B, and the other end of the spring B is fixedly connected to the outer wall of the bracket.

[0016] Working principle: During the treatment of the patient's nail disease, the ring body needs to be worn on the patient's nail disease position first, and the limiting strap is contracted by pulling the limiting strap, and the limiting strap is fixed with the fastening bolt passing through it, and the ring body is installed on the outer wall of the patient's finger to ensure stability during subsequent operations.

[0017] First, the arc block is moved to move laterally along the inner wall of the annular frame to change the lateral position of the puncture needle. After moving to the diseased position, the medical staff presses the puncture needle to make the puncture needle penetrate the patient's diseased nail position. After releasing the puncture needle, the force of spring B drives the puncture needle to move outward and reset, ensuring that the patient's diseased nail position is opened, ensuring the accuracy and treatment effect of the drug administration process.

[0018] After the puncture is completed, the ring body does not need to be removed. The outer rod is pulled outward to separate the fixing block provided on the outer wall of the outer rod from the card slot, thereby releasing the fixing effect of the outer rod, and the outer rod is rotated to drive the rotating shaft to rotate along the inner wall of the ring body, so that the rotating shaft drives the ring frame to flip 90 degrees, so that the ring frame drives the puncture needle away from the patient, and drives the injection mechanism provided on the top to move to the front end of the patient's finger;

[0019] The outer rod is loosened, and the force of spring A is used to drive the outer rod to move inward, so that the fixing block provided on the outer wall of the outer rod is plugged and fixed with the card slot, so as to achieve the effect of clamping and fixing the outer rod and the annular frame, and the embedder provided on the injection mechanism is inserted between the patient's nails, and then the specified therapeutic liquid is extracted through the syringe, and the syringe after the liquid is extracted is installed on the top of the injection platform, and the syringe is connected to the injection platform by rotation to ensure stability during the injection process, and the therapeutic liquid is evenly applied and injected into the patient's nail disease position along the injection hole opened on the transmission tube and the embedder by pushing the syringe, so as to achieve the effect of drug administration.

[0020] The present invention provides a drug delivery device for treating nail diseases, which has the following beneficial effects:

[0021] 1. The present invention integrates the puncture and drug administration functions into one, changing the cumbersome process of traditional treatment of infectious nail diseases, which requires puncture with a puncture needle and then smearing and injection. Medical staff do not need to change multiple sets of medical equipment during the treatment process. All operations from puncturing and opening the nail disease to smearing and injecting the drug solution can be completed with one device, which greatly saves treatment time and significantly improves treatment efficiency.

[0022] 2. The present invention provides a movable puncture needle and an injection mechanism that can be precisely positioned, and can flexibly adjust the positions of the puncture needle and the inserter according to the specific location of the patient's nail disease, thereby ensuring that both puncture and drug administration can accurately act on the diseased area.

[0023] 3. The present invention uses the design of the ring body with a limit strap and a fastening bolt to facilitate the device to be firmly worn on the patient's finger, ensuring that the device will not shake or shift during treatment. At the same time, the operation of the flip mechanism and the injection mechanism is simple and convenient, and the fixed and separated design of the outer rod and the card slot makes the flipping of the ring frame easy to achieve, conveniently switching the puncture and drug delivery functions, and reducing the difficulty of operation for medical staff.
