Articulating Shaper
A shaper for reaming tissue includes an articulating head operably connected to a shaft. Incremental deployment allows for a unique utility in shaping a cavity suited to the particular morphology, that is, a more customizable cavity shape may be achieved.
1 . A shaper for use in bone and tissue in a mammal comprising:
a shaper body having a proximal end and a distal end adapted to engage the bone and tissue in the mammal;
a shaping head operably engaged to the distal end of the shaper body, the shaping head having a first neutral position in line with a central line of the shaper body and a second fully articulated position offset at least 130 degrees from the center line of the shaper body; and
a handle operably engaged to the proximal end of the shaper body adapted to articulate the shaping head from the neutral position to the fully articulated position.
2 . The shaper of claim 1 wherein the shaper body includes an actuator operably engaged to the proximal end adapted to incrementally move the shaping head to a fixed position anywhere between the neutral position and the fully articulated position.
3 . The shaper of claim 1 wherein the shaping head has a width and the shaper is configured to remove the bone and tissue to create a void at least two times the width of the cutting head.
4 . The shaper of claim 1 wherein the shaper has a diameter in the range of about 3 mm to 7 mm.
5 . The shaper of claim of 1 wherein the shaping head is configured to move in a sweeping motion.
6 . The shaper of claim 1 wherein the shaping head is configured to move in a linear scraping motion.
7 . A two stage articulating shaper for use in bone and tissue in a mammal comprising:
a shaper body having a proximal end and a distal end adapted to engage the bone and tissue in the mammal;
a shaping head operably engaged to the distal end of the shaper body, the shaping head having a neutral position in line with the shaper body, a first stage cutting position and a second stage deployment perpendicular from a center line of the shaper body maintaining the first stage cutting position; and
a mechanism adapted to move the shaping head from the neutral position to the first stage cutting position and the second stage deployment position.
8 . The shaper of claim 7 wherein the first stage cutting position is between the neutral position and a fully articulated position in the range of about 90 degrees from the neutral position.
9 . The shaper of claim 7 wherein the shaping head is configured to maintain any position between the neutral position and the fully articulated position.
10 . The shaper of claim 7 wherein the shaping head is configured to move in a sweeping motion.
11 . The shaper of claim 7 wherein the shaping head is configured to move in a linear scraping motion.
12 . A method of removing bone and tissue from a mammal comprising:
inserting a shaper having a shaping head in a first neutral position in line with a central line of the shaper body into a mammal;
articulating the shaping head from the neutral position to a fully articulated position in a sweeping motion to cyclically sweep out a cavity; and
fixing the shaping head in a desired position;
moving the shaper with the shaping head in a fixed position to scrape the tissue and bone out of the cavity.
13 . The method of claim 12 further including the step of:
rotating and/or moving the shaper longitudinally to create the desired cavity shape.
14 . The method of claim 12 further including the step of creating a cavity having a width at least two times a width of the shaping head.
15 . The method of claim 12 further including the step of:
incrementally rotating the shaper to create the desired cavity shape.
16 . A method of providing tools and instructions for removing bone and tissue from a mammal comprising:
providing a shaper comprising
a shaper body having a proximal end and a distal end adapted to engage the bone and tissue in the mammal;
a shaping head operably engaged to the distal end of the shaper body, the shaping head having a first neutral position in line with a central line of the shaper body and a second fully articulated position offset at least 130 degrees from the center line of the shaper body; and
a handle operably engaged to the proximal end of the shaper body adapted to articulate the shaping head from the neutral position to the fully articulated position; and
providing instructions for using the shaper comprising the steps of:
inserting the shaper having a shaper head in the first neutral position in line with a central line of the shaper body into a mammal; and
articulating the shaper head to from the neutral position to the fully articulated position in a sweeping motion to cyclically sweep out a cavity.
17 . The method of claim 16 wherein the step of providing instructions further includes the step of:
fixing the shaping head in a desired position to scrape the tissue and bone out of the cavity.
18 . The method of claim 16 further wherein the step of providing instructions further includes the step of:
moving the shaper longitudinally to create the desired cavity shape.
19 . The method of claim 16 wherein the step of providing instructions further includes the step of:
incrementally rotating the shaper to create the desired cavity shape.
20 . The method of claim 16 wherein the step of providing instructions further includes the step of:
creating a cavity having a width at least two times a width of the shaping head.
