Stereotactic guidance device
First Claim
1. A surgery guidance device comprising:
- a base for securing to a table, said base forming an adjustable guidance carrier for positioning over a patient'"'"'s body characterized by two horizontally disposed spaced apart rigid lower support members each having a length with a first end and a second end, said lower support members having upwardly facing support legs positioned perpendicular thereto coupling horizontally disposed spaced apart rigid upper support members placed in a parallel plane to said lower support members, each upper support member having a length with a first end and a second end attached to said support legs, each upper and lower support member as joined by said support legs forming a side member assembly, and each end of each upper support member having a cross brace member disposed therebetween;
an interface frame assembly slidably disposed within said upper support members, said frame having an upper surface and a width and a length less than a length of said base, said upper surface of said interface frame assembly including at least one side rail crossing said width of said interface frame assembly, each said side rail having a guide track on its upper surface;
an arch frame assembly slidably disposed within said interface frame assembly having a width and a length, said arch frame assembly width less than said width of said interface frame assembly;
an alignment slat secured to said arch frame assembly with said guide track operatively associated with said alignment slat;
an arc member pivotally coupled to said arch frame assembly;
means for tilting said arc member; and
a delivery system pivotally coupled to said arc member.

Abstract
A portable stereotactic guidance having coordinated targeting and delivery assemblies. Aligning and orientating a medical instrument in a three-dimensional plane by specific cartesian coordinates or live imaging. The device may operate in conjunction with an X-Ray or CT scanner so as to image a patient allowing the surgeon to accurately introduce a probe such as a needle, cannula, or guide wires into the human body at a preselected angle. The device fits over a patient using and is used in conjunction with an alignment guide to read X, Y and Z coordinates as well as associated angles for precise orientating of a delivery system. Provision is made for aligning of the device can be performed during real time X-Ray or scanning through a target assembly having cross hatching to target an object for use as a reference point. Once a target is set, the delivery system is aligned by sliding the delivery system within a cartesian coordinate system thereby rotating the stir ups along a polar coordinate system. The delivery system can be aligned by rotation of the stir ups to either specified angels or desired images. The delivery system can be used independently from the targeting system.

17. A surgery guidance device for use in combination with a X-Ray or CT scanner comprising:
-
a base defined by two horizontally disposed spaced apart rigid lower support members each having a length with a first end and a second end with upwardly facing support legs positioned perpendicular thereto coupling horizontally disposed spaced apart rigid upper support members placed in a parallel plane to said lower support member, each upper support member having a length with a first end and a second And attached to said support legs, and each end of each upper support member having a cross brace member disposed therebetween; a interface frame assembly slidably disposed within said upper support members, said interface frame having a width and a length less than a length of said base support member; a means for moving said interface frame assembly along a length of said base; an arch frame assembly slidably disposed within said interface frame assembly having a width and a length, said arch frame assembly width less than said width of said interface frame assembly; a means for moving said arch frame assembly along a width of said interface frame; an arc member coupled to said arch frame assembly defined as a substantially inverted U-shaped housing pivotable along said width of said arch frame assembly; means for tilting said arc member, said means for tilting including a means for securing said arc member in an angular position; a delivery system pivotally coupled to said arch member; an alignment target frame assembly defined by at least one vertically disposed leg slidable along the longitudinal length of one said side member coupled to said interface frame assembly; and a means for securing said base to an X-Ray or scanning table. - View Dependent Claims (18, 19, 20)
