Benefits of technology

[0007] In another aspect, the present invention provides a kit for treatment of a lesion of a bone. The kit includes a first container adapted for holding a first volume of bone void filler and a second container adapted for holding a second volume of bone void filler, and a hand-held ultrasonic device adapted for determining the volume of a lesion of a bone and indicating which of the first container or the second container corresponds to the volume of the lesion.

Problems solved by technology

However, these methods are expensive, time-consuming, and inconvenient.

Abstract

A surgical instrument for assessing tissue characteristics such as tissue density and volume is disclosed. The surgical instrument is hand-held and includes transducers adapted for emitting and / or receiving acoustic signals. The surgical instrument utilizes pulse-echo to determine tissue characteristics. The surgical instrument may be utilized to determine such things as the size of a lesion and whether the lesion has been completely removed or filled with graft material.

Description

FIELD OF THE INVENTION [0001] The present invention is directed to improved instrumentation for assessing tissue characteristics and methods of using such instrumentation. More particularly, in one aspect the present invention is directed toward instruments and methods for assessing the size of a lesion. BACKGROUND OF THE INVENTION [0002] The present invention relates to the assessment of tissue density and related tissue characteristics. The assessment of tissue density is often required in orthopaedic procedures to evaluate the available treatment options and rehabilitation programs. Current techniques for treating lytic and cancerous lesions include debriding the lesion and filling the remaining defect with allograft materials. Advanced treatment options include the use of osteoinductive and osteoconductive materials to heal the lesion. These materials require accurate assessment of the lesion to ensure that the appropriate amount of biological agent is introduced into the lesion...
