The utility model discloses a take seal wire of scale, including seal wire main part, seal wire head end, mark point, the one end of seal wire main part is provided with the seal wire head end, the length of seal wire head end is 30mm, in the seal wire main part and be close to the one end of seal wire head end is provided with eight the mark point. The utility model discloses it is originated from the end of seal wire head end, every 5mm has a light-tight sign, set up 8 in succession, this seal wire and IVUS together send into coronary artery, when pathological change location, regard the seal wire head end as pathological change distal end location district, measure pathological change length by IVUS, thereby it is clear that pathological change is in which several mark regions that this seal wire shows, according to these several signs, implant the support, this seal wire helps renal failure's patient, or improve the accuracy that the support was implanted to the allergic patient of contrast medium, reduce the degree of difficulty of operation, have stronger using value.

Description

Guide wire with scales

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a seal wire of taking scale.

Background

At present, the cardiac intervention guide wire used clinically mainly comprises a guide wire body and a guide head, is mainly used for probing or imaging blood channels, and needs a contrast medium during imaging, but the contrast medium can cause certain damage to renal function, so patients with renal failure can not use the contrast medium, or patients allergic to the contrast medium can not use the contrast medium, therefore, the patients can only clearly evaluate lesions by using intravascular ultrasound (IVUS) and implant a stent, which is practically equivalent to blind human images under X-rays, so that the difficulty of the operation is greatly improved, and the success rate and the accuracy of the operation are reduced.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a seal wire with scales for solving the problem.

The utility model discloses a following technical scheme realizes above-mentioned purpose:

the utility model provides a take seal wire of scale, includes seal wire main part, seal wire head end, mark point, the one end of seal wire main part is provided with the seal wire head end, the length of seal wire head end is 30mm, in the seal wire main part and be close to the one end of seal wire head end is provided with eight the mark point.

Preferably: the length of the first mark point close to the guide wire head end and the tail of the guide wire head end and the distance between two adjacent mark points are both 5 mm.

Preferably: the mark point is embedded on the guide wire main body and is made of tungsten or platinum.

Preferably: the material of seal wire main part is stainless steel, and the diameter is 0.36mm, the seal wire main part with the total length of seal wire head end is 1900 mm.

Compared with the prior art, the beneficial effects of the utility model are as follows:

starting from the tail end of the guide wire head end, every 5mm of guide wire head end is provided with a light-tight mark, 8 light-tight marks are continuously arranged, the guide wire and the IVUS are sent into a coronary artery together, when lesion is positioned, the guide wire head end is used as a lesion far-end positioning area, the length of lesion is measured by the IVUS, and therefore the lesion is determined in which mark areas displayed by the guide wire, and a stent is implanted according to the marks.
