Technical Field

The utility model belongs to the technical field of medical instrument, a from formula of expanding anchor form lung puncture locator external member with energetically horse line is related to.

Background

In recent years, more and more patients with lung nodules have difficulty in early diagnosis of lung nodules, lack of specificity in clinic, have various imaging appearances, are difficult to judge whether benign or malignant, and often cause misdiagnosis to delay treatment. With the improvement of minimally invasive technology, pulmonary nodules are usually excised through small thoracoscopic chest incisions, the search of pulmonary nodules under thoracoscopic surgery is the key of success or failure of surgery in the surgery, the pulmonary nodules are small, the pulmonary tissues are compressed and compacted and then are difficult to guide the excision of the nodules through palpation, and the excision wound of lung lobes or lung sections is too large, so preoperative puncture positioning is very important. In the prior art, the thin needle lung puncture positioning technology under CT positioning is widely applied to pulmonary nodule surgical resection, but displacement, fracture and even shedding are easy to occur in the surgery, and the respiratory motion of a patient can also cause the displacement of a positioning needle, so that the surgery fails or too many lung tissues are resected, and the pain is brought to the patient.

Disclosure of Invention

The hollow push needle can be fixed through the nut, so that the position of the conical puncture needle is fixed, and the nut can move at the starting point and the ending point.

Furthermore, the strong guy wire of the self-expandable anchor-shaped positioner of the positioner kit penetrates through the hollow outer trocar, then penetrates through the hollow push needle, the hollow push needle is sleeved into the hollow outer trocar, the self-expandable anchor-shaped positioner is collected into the hollow outer trocar by pulling back the strong guy wire, and the needle point is fixed at the front end of the hollow outer trocar after the conical puncture needle is pulled back.

Furthermore, after the locator kit pushes the self-expansion anchor-shaped locator out of the hollow outer trocar through the hollow push needle, the self-expansion anchor-shaped locating guide wire is self-expanded to be in an anchor shape and is inversely hung and fixed on lung tissue, so that the self-expansion anchor-shaped locating guide wire is not easy to fall off.

This use novel take vigorous horse line from beneficial effect of formula of expanding anchor form lung puncture locator external member:

1. a self-expansion anchor-shaped lung puncture locator with a strong force mariages is mainly applied to preoperative location of pulmonary nodules, and due to the self-expansion anchor-shaped design, the locator is not easy to fall off.

2. The tip of the puncture needle of the locator kit is conical, so that blood vessels and lung tissues are prevented from being damaged in the puncture process, and the incidence rate of bleeding complications and the damage to the lung tissues in the puncture process are reduced.

3. The strong horse wire of location wire guide area in this locator external member can not remove along with patient's breathing, and strong horse wire matter is flexible, and the locator is difficult for breaking, improves percutaneous lung puncture location and guides efficiency to the operation.
