Abstract
The utility model discloses a body surface locator that is used for CT power traction to lead down aspiration biopsy, by the location identification needle, mark needle and locating plate constitution, two bar plastic slab both ends plane stack overlap joints and fixed with the rivet hinge, formation can be at the folding pivoted locating plate in plane, the fixed three piece planar stainless steels of perpendicular to in interval mark needle and a location identification needle on the locating plate plane, location identification needle position is in the tail end of locating plate, mark that needle and location identification needle interval equal and on same water flat line, location identification needle diameter is with integral multiple greater than flag needle diameter. The utility model discloses simple structure, convenient operation can provide the longitudinal register, and the accurate positioning of biopsy point of puncture is realized to coupled computer horizontal location location, improves the accuracy and the convenience of operation.
Description
Technical field
This utility model relates to technical field of medical instruments, especially relates to a kind of body surface locator for CT machine guided percutaneous needle biopsy.
Background technology
Carrying out aspiration biopsy under CT power traction is led and have been widely used for clinic, biopsy prelocalization is one of committed step of aspiration biopsy, including entering pin mark, entering pin angle and enter the pin degree of depth.But computer can accurately provide horizontal location at body surface, but cannot provide longitudinal register.All the time, when carrying out aspiration biopsy under machine CT power traction is led, all it is dependent on artificial experience and judges its longitudinal register, it is possible to cause centre spot that deviation occurs, also delay positioning time.Research and development one can provide longitudinal register, and the horizontal location provided with computer is worked in coordination, thus accurately quickly determines into pin mark, carries out aspiration biopsy work easily under CT power traction is led, and is the vital task that currently faces of this area.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in construction, convenient and practical, using the teaching of the invention it is possible to provide longitudinal register, the body surface locator for CT machine guided percutaneous needle biopsy of coupled computer horizontal location.
nullFor above-mentioned purpose，The technical scheme of this utility model following structure of employing: a kind of body surface locator for CT machine guided percutaneous needle biopsy，By location mark pin、Mark needle and location-plate composition，It is characterized in: two pieces of bar plastic plate end flat superposition overlap joints，And fix with rivet hinge，Formation can be at the location-plate of flat-folded rotation，Fixed vertical it is spaced in two rustless steel mark needles of plane in the plane of one piece of plastic plate，It is spaced fixed vertical in the plane of another block plastic plate and identifies pin in a rustless steel mark needle and a location of plane，Location mark pin is positioned at the tail end of location-plate，Mark needle is with location mark pin in the same horizontal line，Spacing between mark needle with location mark pin is the most equal，Location mark pin diameter is with integral multiple greater than flag pin diameter，Constitute a kind of body surface locator for CT machine guided percutaneous needle biopsy.
A diameter of 1-2mm of mark needle described above, a diameter of 2-4mm of location mark pin.
When this utility model uses, localizer plane is positioned over position to be punctured, it is longitudinally perpendicular for making mark needle and location mark pin, by rotational positioning plate, after making location-plate and body surface docile, carry out CT scan site of puncture, determine point of puncture on the computer screen, horizontal level line is shown by CT machine, the reflective spot that lengthwise position line is made up of location mark pin and mark needle on localizer, developed by X-ray and form lengthwise position line on the computer screen, horizontal level line is point of puncture with the cross point of lengthwise position line, aspiration biopsy can be proceeded by.The location mark pin diameter of location-plate tail end is significantly greater than the diameter of mark needle, and its reflective spot has significantly difference, utilizes this difference to may determine that CT machine scanning direction, be accurately positioned point of puncture.
This utility model simple in construction, easy to operate, using the teaching of the invention it is possible to provide longitudinal register, coupled computer horizontal location positions, it is achieved being accurately positioned of Biopsy point, improves accuracy and the convenience of operation, has reached the purpose of invention.
