Abstract

The utility model discloses a luminous positioning guide wire which comprises a light source device, an endpoint optical fiber guide wire (or a sidelight optical fiber guide wire), and a connector for connecting the light source device and the guide wire. The luminous positioning guide wire is characterized in that the diameter of a single endpoint optical fiber guide wire or sidelight optical fiber guide wire ranges from 0.25 to 1.0 mm; and the endpoint optical fiber guide wire or sidelight optical fiber guide wire is made of PMMA (polymethyl methacrylate) plastic material or PS (polystyrene) plastic optical fiber material and can give out light after being connected with the light source device. The guide wire can be inserted in a diseased mammary gland catheter and can achieve accurate positioning by marking the diseased mammary gland catheter with lumination, so as to avoid enlargement of excision scope; and for a tiny nidus which can not be touched, the luminous positioning guide wire can also be used with a metal positioning needle and leads to the breast lesion through lumination.

Description

Luminous positioning guide wire

Technical field

This utility model relates to field of medical, is specifically related to the positioning guide wire of a kind of labelling pathological changes latex dust and location breast lesion.

Background technology

At present the pathologic nipple discharge are undergone surgery, during excision pathological changes breast duct, generally adopt in the latex dust dye marker pathological changes latex dusts such as the U.S. orchid of injection, then the lesion region that is colored of excision; Latex dust is cut brokenly easily and is caused dyestuff excessive in the operation, and after normal structure was colored, the excision scope had to blindly enlarge; In addition, dyeing usually influences detecting of minute lesion.

For the biopsy of the intravital small suspicious lesions of mammary gland gland, adopt the mammary gland positioning needle to thrust body of gland at present after, strut the wire guide nook closing member, its barb by means of front end is fixed on the suspicious lesions tissue; The doctor dissects along the direction operation out of shape of positioning needle, searches out small suspicious lesions, and with its excision; Though the metal positioning needle can be located, owing to lack the visual guide to operation pathway, for seeking positioning needle and pathological tissues, the excision scope is often enlarged.

The utility model content

To the problem that exists in the background technology; This utility model provides a kind of luminous positioning guide wire; Overcome the metal positioning needle lacks vision guide when operation deficiency, this luminous positioning guide wire can also provide guide for the operation anatomical path through luminous except the conventional positioning effect; Insert the pathological changes latex dust and make that latex dust is luminous to come labelling pathological changes latex dust, and luminous seal wire softness can not poked latex dust.

In order to achieve the above object, the technical scheme of this utility model employing is following:

A kind of luminous positioning guide wire, it comprises light source device, end points optical fiber seal wire or sidelight optical fiber seal wire and the joint that connects light source device and luminous seal wire.Sidelight that described luminous seal wire is diameter 0.25-1.0mm or end points light-conductive optic fibre, material are PMMA plastic optical fiber or PS plastics, and can be luminous after the light source device is connected.

Described light source device is the led light source of 16-150W or the LASER Light Source of 0.5-5mW.

The beneficial effect of this utility model is following:

The luminous seal wire of this utility model can insert the breast duct of pathological changes, through luminescent marking pathological changes breast duct, reaches pinpoint effect, avoids the expansion of excision scope; To touch less than minimal disease, luminous positioning guide wire also can be used with the metal positioning needle, through luminous guide breast lesion, because the pliability of this luminous positioning guide wire can not poked latex dust, can reduce operation wound to greatest extent.

The specific embodiment

In order this utility model to be made more detailed introduction, do further explanation below in conjunction with accompanying drawing.

Specific embodiment 1:

As shown in Figure 1, a kind of luminous positioning guide wire, it comprises LASERLight Source 1, end points optical fiber seal wire or sidelight opticalfiber seal wire 2 and joint 3.Luminouspositioning guide wire 2 is connected with LASER LightSource 1 throughjoint 3, opens the switch of LASERLight Source 1, and positioningguide wire 2 just can be luminous; After finding the discharge conduit mouth of suffering from breast, conduit mouth surface secretion clearing is appeared newborn hole to clear,luminous seal wire 2 is slowly inserted this latex dust opening; The brightness ofluminous seal wire 2 at this moment is the lesions showed breast duct clearly; To operation visual guiding is provided, reaches pinpoint effect, avoid the expansion of excision scope.

Specific embodiment 2:

As shown in Figure 2, this utility model can also join together to use with traditional metal positioning needle.The metal positioning needle comprises nookclosing member 4 and stylophore 5.To touch less than minimal disease, position and the scope that can clearly perform the operation with metal positioning needle puncture location before the operation.Earlier metal positioning needle integral body is punctured into focus central authorities during use, push positioning needle forward, then fixing nookclosing member 4; Keep its position motionless, softly, the barb (single hook or double hook) that lentamente stylophore 5 withdrawed from up to nookclosing member 4 front ends backward stops when opening, the nook closing member ofmetal positioning needle 4 fixing after; This luminouspositioning guide wire 2 is inserted along the stylophore 5 of metal positioning needle slowly; Barb place untilluminous seal wire 2 being delivered to nook closingmember 4 front ends slowly withdraws from stylophore 5 again, fixing luminous seal wire 2.In the art through theluminous seal wire 2 luminous breast lesion of guiding.

Claims (3)
