Abstract
A scissor-like device is described which can be used to measure the diameter of a tendon graft or bone plug. The device can also be used to hold a tendon graft or bone plug in a fixed position while multiple sutures are inserted in the end thereof. The device includes a pair of arms which are hinged at the proximal end. The inner surface of each arm includes a series of semicircular sizing sleeves which mate with one another to form a series of cylindrical sleeves of increasing diameter. A tendon graft or bone plug can be placed in the series of sleeves to determine the proper diameter of the graft or plug. Various measuring indicia are provided along the arms of the device to provide an indication of both the diameter and length of tendon tissue to be measured.
Claims23
A medical device for measuring the diameter of a piece of body tissue, comprising:
- first and second arms, each arm having a series of semicircular shaped sizing sleeves, each sleeve on one arm being positioned to mate with another identically sized sleeve on the other arm to provide a circular sizing sleeve when said first and second arms are placed in parallel juxtaposition with one another, and
- a means for allowing puncture of said tissue, said means for allowing puncture located through at least one of said arms at at least one of said semicircular shaped sizing sleeves.
A medical device for holding body tissue, comprising:
- first and second arms, each arm having a distal and proximal end;
- hinge means at said proximal end of each arm to allow said arms to open and close on one another;
- a series of pairs of mating semicircular shaped sizing sleeves so constructed and arranged for holding tissue therein, one of said mating semicircular sleeves of a pair being located on said first arm and the other of said mating semicircular sleeves of a pair being located on said second arm such that when said arms are closed, said sleeves are in registry to define a tubular opening, said sleeves being slightly smaller than the diameter of the tissue to be held so that when the tissue is inserted between said arms at said sizing sleeves and said arms are closed, said tissue is held between said arms in said sleeves by compression;
- and
- a means for allowing puncture of said tissue, said means for allowing puncture located through at least one of said arms at at least one of said semicircular shaped sizing sleeves.
A device for holding body tissue, comprising:
- first and second arms, each arm having a distal and proximal end;
- hinge means at said proximal end of each arm to allow said arms to open and close on one another;
- at least one pair of semicircular shaped sizing sleeves constructed for holding tissue therein, one of said sleeves being located on said first arm and the other of said sleeves being located on said second arm such that when said arms are closed, said sleeves are in registry to define a tubular opening within which tissue can be held, said sleeves being slightly smaller than the diameter of the tissue to be held so that when the tissue is inserted between said arms at said sizing sleeves and said arms are closed, said tissue is held between said arms in said sleeves by compression;
- and
- a series of three cavities extending through each of said arms at said semicircular shaped sizing sleeves, each of said cavities having an axis perpendicular to an axis of said sizing sleeve and so constructed and arranged to allow said tissue to be punctured through each of said cavities at a predetermined location when said tissue is held in said arms at said sizing sleeve, said cavities being located to allow sutures to be inserted in a tissue at a fixed predetermined distance from one another.
A device for compressing a bone plug to enhance uniformity of said plug, comprising:
- first and second arms hingedly attached at longitudinal ends thereof to allow said arms to be closed upon each other;
- said arms having a series of mating semicircular shaped sleeves that form circular sleeves of different diameters when the arms are closed and that are slightly smaller than said bone plug to compress said plug when said plug is inserted between said arms at said sleeves and said arms are closed upon each other to compress said plug into a uniform circumference;
- and
- means located through at least one of said arms on said sleeves for allowing puncture of said bone plug when said bone plug is inserted between said arms.
A medical device for measuring the length of a piece of body tissue, comprising:
- first and second arms, said arms having an inner surface and an outer surface, said arms being hinged together at proximal ends thereof to allow said arms to be moved from a closed position in which said inner surfaces are closed upon one another to an open, butterfly position in which said outer surface of both arm extends in a straight line to allow said outer surfaces to form a ruler, wherein each arm includes a series of semicircular shaped sizing sleeves, each sleeve being positioned to mate with another identically sized sleeve on the other arm to provide a circular sizing sleeve when said first and second arms are placed in parallel juxtaposition with one another;
- measurement indicia engraved upon said outer surfaces and extending continuously from a distal end of one arm to at least a portion of said proximal end of said other arm to allow a length of body tissue that is longer than the length of one arm to be accurately measured;
- and
- a series of cavities extending through each of said arms at said semicircular shaped sizing sleeve, said cavities each having axis perpendicular to said axis of said sizing sleeve to allow puncture of said cavities and said tissue at a predetermined location when said tissue is held in said arms at said sizing sleeve.
A medical device, comprising:
- first and second arms, each arm having distal and proximal ends;
- hinge means joining proximal ends of said arms to allow said arms to open and close on one another;
- at least one pair of semicircular shaped sizing sleeves located on said arms, one of said sleeves being located on said first arm and the other of said sleeves being located on said second arm such that when said arms are closed, said sleeves are in registry to define a tubular opening, said sleeves being constructed for holding tissue therein, said sleeves being slightly smaller than the diameter of the tissue to be held so that when the tissue is inserted between said arms at said sizing sleeves and said arms are closed, said tissue is held between said arms in said sleeves by compression;
- a series of cavities extending through each of said arms at said semicircular shaped sizing sleeves, said cavities each having an axis perpendicular to an axis of said sizing sleeves and constructed to allow puncture of said cavities and said tissue at a predetermined location when said tissue is held in said arms of said sizing sleeves;
- a measurement indicia engraved upon an outer surface of said first and second arms and extending continuously from a distal end on one arm to at least a portion of said other arm to allow a length of body tissue that is longer than the length of one arm to be accurately measured;
- gripping means attached to said first and second arms for providing a gripping hold to open and close said arms without touching the portion of said arms having said semicircular shaped sizing sleeves;
- and
- locking means for stabilizing said arms in a lock position.
