Abstract

The utility model discloses a pulmonary nodule positioning needle which comprises a metal wire, a pushing rod and a puncture needle, wherein the metal wire is in a spring structure formed by spirally and densely winding a monofilament, the head end of the metal wire is in a hook shape, the tail end of the metal wire is connected with a nylon wire through a connecting pipe, the tail end of the pushing rod is connected with a pushing handle, and the tail end of the puncture needle extends into and is fixed in the puncture needle handle. The metal wire is made of a nickel-titanium alloy material, the metal wire is more flexible due to the close winding of the gold wire made of the nickel-titanium alloy material and can effectively protect human tissues, the tail part of the metal wire is connected with a nylon wire, so that the focus position is easier to position and is not easy to shift, the damage to a human body is smaller, and the metal wire brings convenience to thoracoscopic pulmonary nodule resection.

Description

Pulmonary nodule positioning needle

Technical Field

The utility model relates to the technical field of positioning needles, in particular to a pulmonary nodule positioning needle.

Background

At present, full thoracoscopic surgery is a main means for diagnosis and treatment of pulmonary nodules, but the position of a pulmonary nodule focus is easily positioned in the operation and is difficult to accurately position, the difficulty of the operation is increased, and a positioning mechanism is hard in material and is easy to damage human tissues, so that a pulmonary nodule positioning needle is provided.

SUMMERY OF THE UTILITY MODEL

The present invention is directed to a pulmonary nodule positioning needle to solve the above problems of the background art.

In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a pulmonary nodule locator needle, includes wire, push rod and pjncture needle, the wire is the monofilament and passes through the spring structure that the spiral is close around to form, the head end of wire is and colludes the form, and the end is connected with the nylon wire through the connecting pipe, the end-to-end connection of push rod has the propelling movement handle, the end of pjncture needle stretches into and is fixed in the pjncture needle handle.

As a further optimization of the technical scheme, the push rod is sleeved with a protective sleeve, the inner diameter of the protective sleeve is larger than the outer diameter of the push rod, and the length of the protective sleeve is larger than that of the push rod.

As a further optimization of the technical scheme, the middle part of the puncture needle handle is arranged in an arc shape, and an insertion channel for inserting the pushing rod is arranged inside the left end of the puncture needle handle.

Compared with the prior art, the utility model has the beneficial effects that: the metal wire is made of a nickel-titanium alloy material, the metal wire is more flexible due to the close winding of the gold wire made of the nickel-titanium alloy material and can effectively protect human tissues, the tail part of the metal wire is connected with a nylon wire, so that the focus position is easier to position and is not easy to shift, the damage to a human body is smaller, and the metal wire brings convenience to thoracoscopic pulmonary nodule resection.
