Abstract
An improved flexible medullary reamer for shaping the medullary space of bones. The shaft is comprised of a single solid element. To permit the use of an elongated guide element, the shaft may be axially bored throughout its length. Attached to the shaft's opposite ends respectively, a cutting head and a means of connecting the shaft to a drive mechanism. To compliment the shaft, said cutting head and connecting means may be centrally bored.
Claims9
In a flexible medullary rotational reamer for clearing, enlarging or otherwise modifying the medullary space of bones, having a flexible shaft with a cutting head at one end and an adaptor piece at its opposite end for connecting said shaft to a rotational drive element thereby causing rotation of the shaft, said shaft having a small diameter axial bore throughout its length to receive an elongated guide element, the improvement comprising:
- said flexible shaft being comprised of a material from the group consisting of carbon fiber composites.
In a flexible medullary rotational reamer for clearing, enlarging or otherwise modifying the medullary space of bones, having a flexible shaft with a cutting head at one end and an adaptor piece at its opposite end for connecting said shaft to a rotational drive element thereby causing rotation of the shaft, said shaft being comprised of a material from the group consisting of thermoplastics and composites thereof.
A flexible medullary rotational reamer for clearing, enlarging or otherwise modifying the medullary space of bones, comprising:
- a flexible monolithic shaft comprised of a material from the group consisting of fiber reinforced composites,
- said shaft with a rotational cutting head at one end thereof and a rotational drive coupling at an opposite end thereof,
- said shaft having an axial bore for accepting a guide element.
A flexible medullary rotational reamer for clearing, enlarging or otherwise modifying the medullary space of bones, comprising:
- a flexible monolithic shaft comprised of a synthetic plastic material,
- said shaft with a rotational cutting head at one end thereof and a rotational drive coupling at an opposite end thereof,
- said shaft having an axial bore for accepting a guide element.
