Highly-efficient lung puncture positioning device used under CT guidance

Abstract

The invention discloses a highly-efficient lung puncture positioning device used under CT guidance. The highly-efficient lung puncture positioning device comprises a base, a transverse sliding base, asemicircular angle adjusting base and a needle inserting angle adjusting base, wherein a second puncture receding hole corresponding to first puncture receding holes is arranged at the central part of the transverse sliding base; a first sliding column capable of sliding along a first sliding groove is arranged on the transverse sliding base and respectively located at the upper side and the lower side of the second puncture receding hole; and a second sliding groove extending in the longitudinal direction of the transverse sliding base is arranged on the transverse sliding base and respectively located at the left side and the right side of the second puncture receding hole. According to the invention, under the guidance of CT, the highly-efficient lung puncture positioning device can accurately puncture the focus of a patient, can guide a puncture needle to rapidly and accurately puncture, shortens the operation time, decrease the operation risk, reduces complications, reduces the labor intensity of medical staff and facilitates early rehabilitation of the patient.

Description

technical field [0001] The invention relates to the technical field of medical devices for lung diseases, in particular to an efficient lung puncture positioning device under the guidance of CT. Background technique [0002] With the increasing air pollution, the incidence of lung diseases is getting higher and higher. Common lung diseases in Linping include lung cancer, pulmonary fungal infection, tuberculosis, and benign tumors in the lungs. Sometimes it is difficult to diagnose qualitatively. Pathological types need to choose a reasonable treatment plan. Percutaneous lung biopsy is usually used clinically to assist diagnosis or treatment. [0003] CT-guided percutaneous lung biopsy has a wide range of applications in the diagnosis of pulmonary diseases, and has many clinical applications. CT cross-sectional scanning has good spatial resolution and density resolution, and can accurately display the size, location and internal conditions of the lesion, as well as the anato...

Problems solved by technology

[0004] At present, when medical personnel perform lung biopsy under the guidance of CT, they first use metal materials on the body surface of the puncture target as a reference object, and through CT scans, according to the relationship between the lung lesions and the metal materials on the scan map, to determine The puncture point and puncture angle, and then the medical staff will puncture with bare hands. This puncture method is mainly based on the experience and technical level of the medical staff to puncture. Multiple options to adjust the puncture angle and puncture depth, long operation time, increase the risk and complications of the operation, not only increase the labor intensity of the medical staff, but also bring greater pain to the patient, and to the lungs of the medical staff. Puncture work brings great inconvenience
