Abstract
For a rapid and accurate performance of surgery for the immobilization of vertebrae an implantation system is suggested in the case of which the surgical implements such as drills, chisels, bone milling or routing implements, implant guide implements, cooperate with an ancillary device, which renders possible an exact and speedy mounting of the respectively desired implement. The ancillary device may be an elongated guide instrument which comprises guide rails or a guide cylinder and a spreading device. A spacer, which is inserted into a gap between vertebrae after the same have been urged apart, may also be designed in the form of an auxiliary device.
Claims24
An implantation system for immobilizing vertebrae, said system comprising:
- at least one guide instrument for mounting on vertebrae to be immobilized;
- said guide instrument comprises at least two elongate, parallel guide rails assembled to form a unitary component, each of said guide rails having a longitudinal groove for guiding and exactly positioning surgical implants to be employed for surgery on the vertebrae, wherein said longitudinal grooves extend in a longitudinal direction of said guide instrument and face one another;
- at least one elongate surgical implement guided with said guide instrument, said surgical implement having elongate first guide means for cooperating with said longitudinal grooves of said guide rails of said guide instrument;
- and
- surgical implants having means for immobilizing vertebrae, said surgical implants having second guide means for cooperating with said longitudinal grooves of said guide rails of said guide instrument.
An implantation system for immobilizing vertebrae, said system comprising:
- at least one guide instrument for mounting on vertebrae to be immobilized;
- and
- said guide instrument comprises at least two elongate, parallel guide rails assembled to form a unitary component, each one of said guide rails having a longitudinal key for guiding and exactly positioning surgical implants to be employed for surgery on the vertebrae, wherein said longitudinal keys extend in a longitudinal direction of said guide instrument and face one another;
- at least one elongate surgical implement guided with said guide instrument, said surgical implement having elongate first guide means for cooperating with said longitudinal keys of said guide rails of said guide instrument;
- and
- surgical implants having means for immobilizing vertebrae, said surgical implants having second guide means for cooperating with said longitudinal key of said guide rails of said guide instrument.
An implantation system for immobilizing vertebrae, said system comprising:
- at least one guide instrument for mounting on vertebrae to be immobilized;
- and
- said guide instrument is in the form of an elongate, tubular component with internal elongate guide keys for guiding and exactly positioning surgical implants to be employed for surgery on the vertebrae, wherein said internal elongate guide keys extend in a longitudinal direction of said guide instrument and face one another;
- at least one elongate surgical implement guided with said guide instrument, said surgical implement having elongate first guide means for cooperating with said internal elongate guide keys of said guide instrument;
- and
- surgical implants having means for immobilizing vertebrae, said surgical implants having second guide means for cooperating with said internal elongate guide keys of said guide instrument.
