[0022] Reference Figure 1 The utility model provides a pulmonary nodule positioning system, including an adjustment bracket 1 and a laser light unit 2, wherein the laser light unit 2 includes a lamp body structure 21 and a positioning rod structure 22, wherein one end of the lamp body structure 21 is connected to the adjustment bracket 1 and the other end thereof is detachably connected to the positioning rod structure 22, and the adjustment bracket 1 can adjust the height and angle of the lamp body structure 21 and the positioning rod structure 22;

[0023] The positioning rod structure 22 can be displayed during CT imaging, so the positioning rod structure 22 is preferably made of a material that can be displayed during CT imaging. In this embodiment, the positioning rod structure 22 is further preferably made of stainless steel.

[0024] In actual use, the patient lies on the CT equipment, and adjusts the height and angle of the lamp body structure 21 and the positioning rod structure 22 by adjusting the bracket 1. The equipment is continuously turned on, adjusted and turned off to determine the positioning position. When the positioning rod structure 22 is accurately located at the puncture point on the CT image, the CT equipment is turned off, and the operator removes the positioning rod structure 22. At this time, since the positioning rod structure 22 is not connected to the lamp body structure 21, the light beam can be emitted from the end of the lamp body structure 21, and the light beam is actually consistent with the positioning of the positioning rod structure 22. The light direction of the light beam accurately points to the puncture point, and then the operator can insert the needle body along the same direction of the light beam, thereby effectively ensuring accurate positioning, avoiding repeated needle insertion, and alleviating the patient's pain.

[0025] As an optional embodiment, the adjustment bracket 1 includes a base 11, a height adjustment mechanism 12 and an angle adjustment mechanism 13. The base 11 is preferably a plate-like structure with a large coverage area, which can play a role of stable support.

The top of the height adjustment mechanism 12 is connected to one end of the angle adjustment mechanism 13, and the other end of the angle adjustment mechanism 13 is connected to the laser lamp unit 2. The angle adjustment mechanism 13 can adjust the angle of the lamp body structure 21 and the positioning rod structure 22.

[0026] As an optional implementation, the height adjustment mechanism 12 is a telescopic rod, which can adjust its own length, so as to effectively adjust the height of the lamp body structure 21 and the positioning rod structure 22, thereby playing a better auxiliary role in the positioning of the puncture point of the lung nodule.

[0027] As an optional implementation, the angle adjustment mechanism 13 is a universal turning rod, which can arbitrarily adjust the angle position of the end, thereby effectively adjusting the angle of the lamp body structure 21 and the positioning rod structure 22, thereby playing a better auxiliary role in the positioning of the puncture point of the lung nodule.

[0028] As an optional implementation, the lamp body structure 21 includes a shell 211 and a lamp body 212. The lamp body 212 is arranged inside the shell 211. The shell 211 supports and protects the lamp body 212. The lamp body 212 can emit a light beam. The shell 211 has an opening at one end away from the adjustment bracket 1, and the opening is detachably connected to the positioning rod structure 22.

[0029] As an optional implementation, the lamp body structure 21 also includes a power supply unit, which is arranged inside the shell 211 and electrically connected to the lamp body 212. The power supply unit can provide power for the lamp body 212. The structure of the power supply unit itself is relatively conventional prior art and is therefore not shown in the accompanying drawings.

[0030] As an optional implementation, the shell 211 is provided with an internal thread on the inner wall at the opening, and the positioning rod structure 22 is provided with an external thread. The shell 211 and the positioning rod structure 22 form a threaded connection, and the threaded connection is easier to disassemble and assemble.
