Description

Technical Field

[0001] The present application belongs to the technical field of medical auxiliary equipment, and specifically relates to a device suitable for detecting thoracic and lumbar spine lesions. Background Art

[0002] Surgical pathology examination refers to the technology of removing diseased tissue from the patient's body by cutting, clamping or puncturing for pathological examination in response to the need for diagnosis and treatment. It is the most important part of diagnostic pathology. It can make a clear histopathological diagnosis for the vast majority of cases submitted for examination and is used as the final clinical diagnosis. At present, the incidence of pathological thoracolumbar fractures is gradually increasing. Due to the deep location of the vertebral body, in order to clarify the pathological nature of the fracture, transpedicular biopsy is often used in clinical practice.

[0003] In the application with the publication number of CN212521852U, a thoracolumbar biopsy device is disclosed, which includes an outer sheath structure, an outer sheath tube, a catheter structure, a catheter body, a puncture structure, a puncture needle, a biopsy structure, a biopsy working rod and a spiral section. The beneficial effect of the utility model is that the living tissue of the target area can be accurately cut and taken out of the body through the coordinated use of the puncture needle, the catheter body, the outer sheath tube and the biopsy working rod. During the operation, it is necessary to use the puncture needle to perform percutaneous directional puncture of the vertebral disease focus through the pedicle under the guidance of the perspective, and at the same time determine the target depth, and then the directional catheter body can be inserted, and then the outer sheath tube is inserted under the guidance of the catheter body, and finally the puncture needle and the catheter body are taken out, and under the guidance of the outer sheath tube, the biopsy working rod is drilled into the predetermined depth, and then pulled out or gently struck out, and the spiral section at one end of the biopsy working rod is used to effectively cut the living tissue of the target area and take it out of the body, so as to facilitate the cleaning of the taken tissue for inspection.

[0004] However, the structure does not use a sawtooth structure for tissue cutting, resulting in low work efficiency and a high rate of human body injury. Utility Model Content
