Description

Human body internal tissue operation positioner with developing mark

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a human body internal tissue operation positioner with development marks, which is suitable for development operation positioning of lung nodules, breast micro tumors, liver tumors, stomach tumors, intestinal polyps and pathological tissues of a urinary system.

Background

The morbidity and mortality of lung cancer have increased year by year, and lung cancer accounts for the first death of malignant tumors by the end of the 20 th century. The five-year survival rate of lung cancer is only 15%, but if some early lung cancer can be discovered and treated early, the five-year survival rate of the early lung cancer can reach 60-80%. With the development of imaging technology and the popularization of routine physical examination, more and more pulmonary nodules with unknown properties are detected. At present, full thoracoscopic surgery is the main means for diagnosis and treatment of pulmonary nodules, but the precise positioning of the pulmonary nodules in the surgery is difficult to achieve, and the difficulty of the surgery is increased.

The pulmonary nodules (SPN) are the first imaging manifestation of most early lung cancers, and the problem of clinical qualitative diagnosis is becoming more and more prominent. At present, there are various methods for locating pulmonary nodules before thoracoscope surgery, the most common method is location by a steel wire with a hook, but the problems that a locating needle is easy to fall off, pneumothorax is easy to form after puncture, and the like exist. The hooked steel wire is positioned without a needle point and a barb, and is difficult to pull back and pierce in the operation process, sometimes loosened, and the difficulty is increased for the operation process of a doctor. And once the hook is not firm, the position is not accurate, the operation time is increased, and even the operation fails.

If can develop a neotype lung nodule not damaged positioner and be used for the isolated tuberculous accurate location before the art of lung, can not only increase the operation security, improve the operation excision rate, still be favorable to further reducing patient medical cost simultaneously, make things convenient for clinical conversion to use and promote, make new technology, new achievement benefit to and extensive SPN patient to the at utmost.

In thoracoscopic surgery, when the suture instrument is used for pushing the hook to position human tissues, the operation is generally carried out under a display. The conventional hook returning material is basically similar to the material used by the stitching instrument, the rotation condition of the hook returning is difficult to show in the operation process, and the difficulty is increased for a doctor to judge the operation process. And once the phenomenon of hook return position inaccuracy is generated, the operation time is increased, and even the operation is failed.

In addition, the positioning of breast micro-tumor, liver tumor, gastric tumor, intestinal polyp and the surgical positioning of pathological tissues of the urinary system all need a novel nondestructive positioning device to perform preoperative accurate positioning, so as to increase the safety of the operation and improve the resection rate of the operation.
