Abstract
An instrument-holding projection imaging vector guide and method of use is provided herein. In one embodiment of the present invention, a instrument-holding projection imaging vector guide is provided comprising a radio-opaque skin entry point member, a frame member and a diaphragm. The radio-opaque skin entry member is used to determine a skin entry point. The diaphragm is used to determine a diaphragm entry point. The radio-opaque skin entry point member and the diaphragm together determine the vector along which an appropriate medical instrument is to follow in order to contact a target inside a patient's body.
Claims19
An instrument-holding projection imaging vector guide, said instrument-holding projection imaging vector guide comprising:
- a radio-opaque skin entry point member, said radio opaque skin entry point member adapted to be placed directly on the skin of a patient so as to define a skin entry point;
- a frame member, said frame member having a first end adapted to be placed on said patient, said frame member having a second end adapted to carry an diaphragm;
- and
- an diaphragm, said diaphragm comprising a perforable membrane.
An instrument holding device, said instrument holding device comprising:
- a frame member, said frame member comprising a first end and a second end, said first end adapted to be placed on a patient, said second end adapted to carry a diaphragm;
- a diaphragm, said diaphragm comprising a perforable membrane, said perforable membrane adapted so as to provide support to an instrument passing therethrough.
A method for using an instrument-holding projection imaging vector guide on a patient, said method comprising the steps of:
- affixing a radio opaque skin entry point member on said patient so as to define a skin entry point, said skin entry point defining one point along a vector;
- affixing a frame member to said patient, said frame member having a first and second end, wherein said second end is adapted to carry a diaphragm, said frame member being positioned about said radio opaque skin entry point member so as to position at least a portion of said diaphragm over said radio opaque skin entry point member;
- determining the location of an diaphragm entry point using a radio opaque device, said diaphragm entry point defining a second point along said vector;
- piercing said diaphragm so as to create an diaphragm entry point;
- and
- advancing an instrument along said vector by going through said diaphragm entry point and said skin entry point so as to contact a target inside said patient.
