Problems solved by technology
[0003] In the prior art, when biopsy puncture is performed on a patient with tumor tissue in the lung, imaging equipment (such as CT) is used to image the patient's lung, and the puncture position, puncture angle and puncture depth are confirmed under the guidance of the imaging equipment. Then the patient held his breath, and the medical staff held a biopsy device to puncture and sample the tumor tissue in the patient's lungs. However, when the patient held his breath, the expansion degree of the chest cavity was inconsistent with the expansion degree of the lung imaging, which would cause the puncture angle and Deviations in puncture depth may even lead to sampling failure and cause conflicts between doctors and patients. In addition, whether the medical staff has rich clinical experience also affects the success rate of puncture sampling. Based on the above problems, a medical oncology puncture positioning device is urgently needed to avoid the expansion of the patient's thoracic cavity. Variations in puncture depth and puncture angle with different triggers

Embodiment Construction
[0039] In order to make the objects and advantages of the present invention more clear, the present invention will be specifically described below with reference to the embodiments. It should be understood that the following text is only used to describe one or more specific embodiments of the present invention, and does not strictly limit the protection scope of the specific claims of the present invention.
[0040] like figure 1 As shown, it is the first embodiment of the present invention. This embodiment provides a puncture and positioning device for medical oncology, which is applied to a puncture biopsy operation. A biopsy device is used together with it, including a positioning bottom shell 10, and a positioning bottom shell 10. The upper end is evenly provided with a plurality of angle identification lines, which also include:
[0041] A lateral angle adjustment mechanism 20, the lateral angle adjustment mechanism 20 is assembled inside the positioning bottom shell 10...

The invention belongs to the technical field of medical equipment, and particularly relates to a medical oncology puncture positioning device which comprises a positioning bottom shell, a transverse angle adjusting mechanism, a longitudinal angle adjusting mechanism, a longitudinal angle adjusting mechanism and a positioning mechanism. The vertical angle adjusting mechanism is assembled on the transverse angle adjusting mechanism; the depth adjusting mechanism is assembled on the vertical angle adjusting mechanism; the expansion limiting mechanism is assembled on the positioning bottom shell; wherein a biopsy device used in cooperation with the depth adjusting mechanism is placed in the depth adjusting mechanism, and the transverse angle adjusting mechanism is operated. The thoracic cavity expansion amplitude of a patient can be limited, it can be guaranteed that the thoracic cavity expansion amplitude of the patient is consistent, meanwhile, the biopsy device can be accurately guided conveniently, and the success rate of puncture sampling is increased.
Description
technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a puncture and positioning device for medical oncology. Background technique [0002] Soft tissue tumor is a disease that seriously endangers human health and life. In recent years, the incidence has gradually increased, and the age of onset has gradually decreased. Early detection, correct diagnosis, and timely treatment have an important impact on prognosis. With the continuous improvement of inspection methods and methods, the accuracy of diagnosis has gradually increased, but there are still a large number of tumors that do not have typical imaging characteristics, making it difficult to diagnose. The correct diagnosis requires a combination of clinical, imaging and pathology. Among them, pathological diagnosis plays a key role in the choice of treatment plan. Needle biopsy using biopsy device is the main way to obtain pathological diagnosis. [0003]...
