Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to a high-precision puncture positioning device for pulmonary nodules. Background Art

[0002] At present, the auxiliary positioning technology for pulmonary nodules mainly includes percutaneous puncture assisted positioning under the guidance of CT imaging, puncture assisted positioning under bronchoscopy, or assisted positioning under virtual 3D images of CT imaging.

[0003] However, since local anesthesia is used in the pulmonary nodule puncture surgery, the patient needs to remain still during the puncture to ensure the accuracy of the puncture. However, it is very difficult for young patients, mental patients, dementia patients, etc. to remain still during the puncture, which is likely to lead to puncture failure and cause damage to the patient. To solve the above problems, a high-precision puncture positioning device for pulmonary nodules is provided herein.

[0004] It should be noted that the above content belongs to the technical cognition scope of the inventor and does not necessarily constitute the prior art. Summary of the Invention

The puncture positioning device of the present invention controls the horizontal limit plate to move to directly above the pressing block, and drives the horizontal limit plate to lift by controlling the lifting of the pressing block. The patient lies on the puncture bed, and at this time, the horizontal limit plate is located above the patient's body, and the two vertical limit plates are respectively located on both sides of the patient's body. Then, the horizontal limit plate is controlled to disengage from the pressing block, and under the action of gravity, the horizontal limit plate supports on the patient's body. Then, the two vertical limit plates are controlled to approach each other. When the vertical limit plates contact the patient's body, the second limiting piece is controlled to be engaged with the corresponding first tooth, so as to realize the limiting of the horizontal limit plate and the vertical limit plate, thereby being able to limit both sides and above of the patient's body, being able to avoid large displacement of the patient before puncture, and the first fixing member can be applicable to patients of different body types, with a high application rate and simple operation at the same time.
