[0002] Puncture is a commonly used surgical term in medicine. It is a diagnostic and treatment technique in which a puncture needle is inserted into the body cavity to extract secretions for testing, inject gas or contrast agent into the body cavity for imaging examination, or inject medicine into the body cavity. In the treatment of nodular thyroid diseases (such as thyroid cancer, etc.), surgical removal of the diseased nodules is the primary treatment method.

[0003] Patent No. CN219439361U proposes a puncture needle, including a needle tube, one end of which is provided with a needle head, and the other end of the needle tube is connected to a spring fixing cylinder, one end of which is provided with a compression spring, and the spring fixing cylinder is provided with an inner hole, and a positioning elastic button is provided in the inner hole. The utility model can effectively protect the needle head when the device is not in use, avoid damage to its tip, and avoid stabbing the body when medical staff take it.

[0004] Currently, when performing puncture in the pain department, the depth of the puncture head inserted into the patient's body is mostly controlled by the medical staff themselves, which requires a high level of skill proficiency. When performing puncture, medical staff with less experience are prone to insufficient or excessive puncture depth due to lack of proficiency and mental tension.

[0005] Therefore, the present application provides a puncture device that can be quickly positioned to meet the needs. Utility Model Content

[0008] As a preferred technical solution of a puncture device capable of rapid positioning of the utility model, the zero point of the scale is kept horizontal with the thread groove, and the length of the puncture needle below the zero point of the scale is equal to the height of the locator.

[0009] As a preferred technical solution of the puncture device capable of rapid positioning of the utility model, a plug is threadedly connected to the place where one end of the screw rod near the thread groove engages with the puncture needle.

[0010] As an optimal technical solution for a puncture device that can be quickly positioned according to the utility model, a protective cover is fixedly connected to the end of the screw away from the thread groove, and the protective cover is made of a retractable material. Second magnetic blocks are fixedly installed on the end of the protective cover away from the screw and the bottom end of the handle, and the two second magnetic blocks attract each other.

[0011] As a preferred technical solution of the puncture device capable of rapid positioning of the utility model, a suction groove is formed at the bottom of the locator, and a shell is detachably connected to the suction groove.

[0012] As a preferred technical solution of a puncture device capable of rapid positioning of the utility model, sterilizing cotton is placed in the shell, and the sterilizing cotton is engaged with the shell, and the puncture needle penetrates the sterilizing cotton and the shell to the outside of the locator.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. When puncturing the patient, first suck the locator onto the body at the desired puncture position, then fix the screw and the threaded groove, insert the puncture needle into the screw and engage it, so that both hands can be freed. At this time, the zero position of the scale on the puncture needle is kept horizontal with the threaded groove, and the needle head of the puncture needle is in contact with the surface of the body skin. Then, adjust the magnifying glass to the zero position on the scale by rotating the sliding rod, and then accurately adjust the position of the magnifying glass by the first damping shaft and the second damping shaft to ensure that the doctor can accurately see the magnified scale numbers on the magnifying glass. At this time, the puncture needle can be squeezed and punctured by holding the handle. During the puncture process, the scale can be magnified and observed through the magnifying glass, which effectively achieves the effect of accurately and quickly reaching the desired puncture depth.

[0016] 2. After the puncture is completed, the puncture needle can be put into the screw, and then the screw can be blocked by a plug to prevent the puncture needle from penetrating. Then the protective cover can be pulled open and extended to wrap the puncture needle as a whole, and fixed to the handle by the second magnetic block, so as to achieve the effect of storing and protecting the used puncture needle, avoiding infection and preventing accidental injury to others.

[0017] 3. Before using the puncture needle for puncture, a disinfectant cotton can be taken out and stuck in the shell without affecting the puncture needle penetrating the locator. Then the shell is stuck in the suction groove so that the two first magnetic blocks are attracted and fixed to each other, thereby achieving the effect of being disinfected by the disinfectant cotton before the puncture needle is inserted into the human body to avoid infection to the human body. The first magnetic block is used for fixing to facilitate the quick removal and replacement of the disinfectant cotton. BRIEF DESCRIPTION OF THE DRAWINGS
