Abstract
A tissue splitting device for splitting a harvested soft tissue to provide a layer of tissue having a uniform thickness and methods for tissue transplantation using uniform layers of tissue.
Claims20
A tissue splitting device comprising:
- a clamp comprising an upper plate and lower mounting plate, wherein the upper plate and lower mounting plate are parallel with one another and define a horizontal space between and parallel to the upper plate and lower mounting plate that can accommodate a harvested tissue,
- wherein the clamp comprises an adjustable arm attached to a support base and to the upper plate which is configured to adjust the vertical position of the upper plate thereby adjusting the height of the horizontal space between the upper plate and lower mounting plate,
- wherein the top surface of the upper plate comprises a display operatively connected to one or more pressure sensors on a bottom surface of the upper plate,
- wherein a top surface of the lower mounting plate is a rough, frictioned surface having a surface roughness Ra of at least 1 μm that prevents tissue placed in the clamp from sliding;
- a blade positioned within the space between and parallel the upper plate and lower mounting plate,
- a cutting blade motor operably connected to the blade, and
- a blade movement channel to which one end of the blade is operatively attached, wherein the blade movement channel is longitudinally aligned with the horizontal space between the upper plate and the lower mounting plate and which, during operation of the device, permits forward movement of the blade from one end of the horizontal space to the other end of the horizontal space.
