Abstract
An apparatus and method for guiding a needle in conjunction with a biopsy using an endocavity medical imaging device, where a non-reusable needle guide, which is relatively inexpensive which grasps the sheathed bracket firm, and holds the same in a set position based upon a protuberance having an intentionally low shear resisting capability.
Claims21
A medical imaging system comprising:
- a transceiver bracket being sized, shaped and configured for securing with an endocavity medical imaging transceiver;
- a transceiver/bracket covering sterile sheath disposed over said medical imaging transceiver and said transceiver bracket;
- a needle guide disposed over said transceiver/bracket covering sterile sheath and cooperating with said transceiver bracket;
- a lock comprising a void in said transceiver bracket and a first pliable side clamp leg with a first side clamp leg protuberance formed thereon;
- said needle guide being attached to said transceiver bracket by said lock;
- and
- said first side clamp leg protuberance being configured to separate from said first side clamp leg at a level of applied force which is lower than a level of applied force which would case said needle guide to be detached from said transceiver bracket.

An endocavity medical imaging system comprising:
- an endocavity medical imaging transceiver, for generating image signals;
- a mounting bracket, coupled to said endocavity medical imaging transceiver;
- a needle guide sized and configured to couple with said mounting bracket so as to create a lock between said needle guide and said mounting bracket when a protuberance mates with a structure;
- and,
- said lock being a single use lock such that once said protuberance is removed from said structure, said lock is theater incapable of affixing said needle guide to said mounting bracket.
2 more elements
An apparatus for guiding a medical instrument in proximity to an endocavity medical imaging transceiver, the system comprising:
- a medical instrument central cannula section, having a cannula longitudinal axis with a hole running along said cannula longitudinal axis, said hole being sized and configured to receive therethrough a medical instrument which is capable of translational motion along said cannula longitudinal axis;
- means for locking said medical inset central cannula section to an exterior surface, such that said medical instrument central cannula section is no longer capable of locking to said exterior surface, after said medical instrument central cannula section is once locked to said exterior surface and then removed from said exterior surface;
- and
- where said exterior surface is an exterior surface of an endocavity member having an endocavity longitudinal axis which is parallel to said cannula longitudinal axis.

A method of guiding medical instruments in conjunction with an endocavity medical imaging transceiver comprising the steps of:
- providing an endocavity transceiver, for generating image signals representative of internal portions of a human body;
- securing a cannula to said endocavity transceiver;
- inserting said endocavity transceiver and said cannula into an orifice of a human body;
- providing a medical instrument;
- manipulating said medical instrument within said cannula;
- removing said endocavity receiver from said orifice;
- pulling said cannula away from said endocavity transceiver such that means coupled to said cannula for securing to said endocavity transceiver is no longer capable of securing said cannula to said endocavity transceiver;
- and,
- disposing said cannula.
6 more elements
A system for guiding needles comprising:
- an endocavity medical imaging transceiver configured for generating image signals representative of interior portions of a human body;
- a mounting bracket coupled to said endocavity medical imaging transceiver;
- a needle guide coupled to said mounting bracket;
- said mounting bracket having a partial sleeve shape configured for coupling with a reduced cross-section medical imaging transceiver middle section of said endocavity medical imaging transceiver;
- said mounting bracket further having a mounting bracket distal end and a mounting bracket proximal end and a mounting bracket needle guide receiving slot disposed between said mounting bracket distal end and said mounting bracket proximal end;
- said mounting bracket further having a mounting bracket protuberance receiving void there;
- said needle guide comprising a needle guide distal end and a needle guide enlarged proximal end and a needle guide central cannula section disposed therebetween;
- said needle guide further comprises a side clamp leg with a side clamp leg protuberance thereon, where the side clamp leg protuberance is separated from the side clamp leg by a substantially circular-shaped void;
- said needle guide further including a needle guide enlarged needle-receiving area having a funnel region for guiding needles into said needle guide central cannula section;
- said side clamp leg protuberance is configured to mate with mounting bracket protuberance receiving void and to secure said needle guide to said mounting bracket;
- said side clamp leg protuberance having a predetermined strength characteristic which is insufficient to keep said side clamp leg protuberance intact with said side clamp leg when said needle guide is removed from said mounting bracket by applying a lifting force on said needle guide in a direction substantially perpendicular to a longitudinal axis of said needle guide central cannula section.
8 more elements
A method of guiding a needle with to a medical imaging transceiver, comprising the steps of:
- providing an endocavity medical imaging transceiver and a transceiver bracket disposed in a transceiver/bracket covering sterile sheath;
- providing a needle guide outwardly of said sheath;
- engaging a lock member which fixes said needle guide to said transceiver bracket;
- positioning said endocavity medical imaging transceiver within a body cavity;
- inserting a needle into said needle guide;
- performing a medical procedure using said needle and said medical imaging transceiver;
- removing said needle from said needle guide;
- applying a force on said lock member which permanently damages said lock member;
- and,
- discarding said needle guide.
