Abstract
Apparatus for inserting pins in osseous material by vibration. The apparatus has a fixed housing with a cavity for moving the pins therethrough. At the proximal end the housing has a clamping device which operates in one direction. Vibration means inside the housing impose vibrations on the pin to insert them into the osseous material.
Claims7
An apparatus for inserting a pin in osseous material by means of vibration comprising:
- a distal section remote from the osseous material during use;
- a proximal outer section located in a vicinity of the osseous material during use, said proximal outer section comprising pin clamping means immobile with respect to both said distal and proximal sections, said clamping means allowing free transport of the pin in a proximal-distal direction only;
- pin vibration means located between said proximal section and said distal section;
- a pin receiver comprising a cavity extending an entire length of said apparatus, said proximal and said distal sections being connected to one another and immobile with respect to one another to thereby keep said proximal section from vibrating with respect to said distal section during use.
