Adjustable implantation positioner and positioning device suitable for lung focus positioning

Abstract

The invention relates to the technical field of medical instruments, and discloses an adjustable implantation positioner suitable for lung focus positioning. The adjustable implantation positioner comprises an anchor end and an anchor line, and the anchor end is configured to be released from a puncture end of a puncture needle to a human body focus and anchored after the puncture needle pierces the human body focus; and the first end of the anchor line is connected with the anchor end, the second end of the anchor line can retreat from the human body along with the puncture needle and extend to the outer side of the body surface of the human body along the puncture path of the puncture needle, and a positioning structure is arranged on the surface, close to the outer side of the body surface of the human body, of the anchor line. A doctor can quickly find the general position of a focus according to the indication of the second end of the anchor line when performing an ablation operation on the focus according to the positioning of the positioner, so that the operation efficiency of the ablation operation of the doctor is improved. Besides, the anchor end is arranged in the focus tissue and is easily shielded by other tissues, so that the anchor end is not easy to be scanned and positioned by the CT, and the long anchor line is easily scanned and displayed by the CT, so that the position of the anchor end can be accurately found along the anchor line.

Description

Technical field [0001] Technical Field The present invention relates to medical devices, and in particular, to a location suitable for pulmonary lesions implantable adjustable positioner, positioning means. Background technique [0002] Application of current clinical needs lung lesion localization techniques, for example the prior art before the treatment of pulmonary nodules thoracoscopic resection, steel wire locator implanted in a patient to achieve a temporary position, the wire retainer integrally disposed within the patient's lesion location place to be marked location of the lesion. However, due to its location in the patient, easy to appear in the actual operation process is obscured by other organizations, leading to the presence of the job is not easily visible during the positioner, which affects the surgery. [0003] Meanwhile, since the lesions in the lungs move with the body's respiratory position, the conventional locator for locating pulmonary lesions can not b...

Problems solved by technology

[0005] The main purpose of the present invention is to provide an adjustable implant positioner and a positioning device suitable for positioning lung lesions, so as to solve the problem that the conventional positioner is installed in the patient's body in the related art, which is easy to be damaged during the actual operation. Blocked by other tissues, the locator is not easy to see during the operation, which affects the operation.
