[0002] In the medical and other related technical fields, in order to reduce the pain of the patient during the treatment process, the patient needs to be injected with anesthetics. The injection of anesthetics requires the use of a puncture needle, which penetrates the patient's epidermis and veins so that the anesthetic can be injected into the patient's veins. The present application discloses a puncture needle for providing a puncture needle device for patient anesthesia.

[0003] According to the puncture needle disclosed in patent publication number CN219070556U, it includes a needle sleeve, a needle seat arranged at the end of the needle sleeve and a needle core. The needle core is movably inserted into the needle sleeve, and the needle core includes a hollow needle body. The two sides of the needle body are respectively provided with a connecting piece and a needle tip, and the needle core can switch between a puncture state and an injection state; in the injection state, the connecting piece abuts against the needle seat, and the needle tip is exposed outside the needle sleeve; in the observation state, the connecting piece is separated from the needle seat, and the needle tip retracts into the inside of the needle sleeve; the connecting piece includes a main body and a plurality of connectors arranged on the main body, the main body is connected with the inside of the needle body, and the plurality of connectors are connected with the inside of the main body.

[0004] Although the above device proposes a puncture needle device for anesthesia, it is inconvenient to control the puncture depth of the puncture needle, and deep puncture may cause harm to the patient during use. Utility Model Content

[0018] (III) Beneficial effects

[0019] Compared with the prior art, the utility model provides a puncture needle with the following beneficial effects:

[0020] The puncture needle is used to puncture the patient's epidermis and vein through the puncture needle body. Before puncturing, the threaded ring is rotated on the threaded barrel to drive multiple connecting rods and support rings to move, thereby adjusting the position of the support ring and the cushion. When performing anesthetic needle puncture, the cushion is brought into contact with the patient's body surface to support the device, and the puncture depth of the puncture needle body is adjusted and controlled. The device is connected to the syringe through the tapered barrel and the sleeve barrel to complete the anesthetic injection. The device is convenient for adjusting the puncture depth of the puncture needle, avoiding damage to the patient caused by excessive puncture depth. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example

[0028] See also Figures 1 to 4A puncture needle comprises: a puncture needle body 1; a supporting structure: the supporting structure is mounted on the puncture needle body 1, and the puncture depth of the puncture needle body 1 is controlled by the supporting structure; a connecting structure: the connecting structure is mounted on the puncture needle body 1, and the puncture needle body 1 is connected to a corresponding position by the connecting structure. The supporting structure and the connecting structure are respectively mounted on the puncture needle body 1, and the puncture depth of the device is adjusted by the supporting structure. After the puncture needle body 1 penetrates the patient's epidermis and vein, the puncture needle body 1 is limited and supported by the supporting structure, so as to control its puncture depth. The puncture needle body 1 is conveniently connected to the syringe through the connecting structure for anesthetic injection. The supporting structure comprises a threaded barrel 2, a threaded ring 3 and a supporting ring 4. The threaded barrel 2 is fixedly connected to the puncture needle body 1, and the threaded ring 3 is threadedly connected to the threaded barrel 2. A plurality of connecting rods 5 are fixedly connected to the threaded ring 3. The supporting ring 4 is fixedly connected to one end of the plurality of connecting rods 5 away from the threaded ring 3. A cushion 6 is fixedly connected to the support ring 4. The threaded barrel 2 is fixedly connected to the puncture needle body 1, and the threaded ring 3 is threadedly connected to the threaded barrel 2. The rotation on the threaded barrel 2 drives the multiple connecting rods 5 to move, thereby adjusting the positions of the support ring 4 and the cushion 6. After the puncture needle body 1 penetrates the patient's epidermis, the cushion 6 is supported on the corresponding position of the patient's body surface, thereby controlling the puncture depth of the puncture needle body 1. The threaded barrel 2 is fixedly connected with a first limiting ring 7 and a second limiting ring 8. The first limiting ring 7 and the second limiting ring 8 are used to limit the two ends of the threaded barrel 2 respectively. The first limiting ring 7 is used to prevent the threaded ring 3 from falling off the threaded barrel 2, and the second limiting ring 8 is used to prevent the support ring 4 from falling off the threaded barrel 2. Being adjusted to a too low position affects the puncture effect of the puncture needle body 1. The connection structure includes a conical tube 9 and a sleeve tube 10. The conical tube 9 is fixedly connected to the puncture needle body 1. The sleeve tube 10 is fixedly connected to the end of the conical tube 9 away from the puncture needle body 1. The sleeve tube 10 is connected through the conical tube 9. The sleeve tube 10 is used to be connected to a syringe for anesthetic injection. An anti-skid pad 11 is fixedly connected inside the sleeve tube 10. The anti-skid pad 11 prevents the sleeve tube 10 from falling off after being sleeved on the syringe, thereby avoiding affecting the injection effect.

[0029] To sum up, the working principle and working process of the puncture needle are as follows: when in use, the device is moved to a suitable position to perform epidermal and venous puncture on the patient; before puncture, the threaded ring 3 is rotated on the threaded tube 2 to drive multiple connecting rods 5 and the support ring 4 to move, thereby adjusting the position of the support ring 4 and the cushion 6; when performing anesthesia needle puncture, the cushion 6 is brought into contact with the patient's body surface to support the device; at the same time, the puncture depth of the puncture needle body 1 is adjusted and controlled; the device is connected to the syringe through the conical tube 9 and the sleeve tube 10 to complete the anesthetic injection.

[0030] The above embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
