Abstract
A medical device that can be used to cut a cornea. The device may include a head that houses a blade. The head and blade can be moved across a ring by a drive assembly. The drive assembly may also move the blade relative to the head to resect the cornea. The head may have a pair of tongues that can slide along corresponding grooves in the ring. The tongues and grooves may be configured so that the head can be loaded onto the ring from a vertical direction.
Claims14
A medical device for cutting a cornea, comprising:
- a ring that has a first sidewall and a second sidewall, said first sidewall having a first groove, said second sidewall having a second groove, said first groove is located a first distance from a base surface of said ring and said second groove is located a second distance from said base surface of said ring, wherein the first distance is different from the second distance;
- a head which has a first tongue that can slide along said first grove and a second tongue that can slide along said second groove, said first tongue being located a first distance from a bottom surface of said head and said second tongue being located a second distance from said bottom surface so that said head can be assembled onto said ring in only one orientation;
- said first tongue being located a first distance from a bottom surface of said head and said second tongue being located a second distance from said bottom surface so that said head can only be assembled onto said ring in one orientation;
- a blade that is coupled to said head;
- and
- a drive assembly that can move said head relative to said ring and said blade relative to said head.
A method for assembling a head to a ring of a surgical device for cutting a cornea, wherein the head houses a blade, comprising:
- pushing a part of tongues of a head into a pair of grooves of a ring in a direction that is essentially perpendicular to a longitudinal axis of the one of the grooves.
A medical device for cutting a cornea, comprising:
- a ring that has a top surface, a first sidewall and a second sidewall, said first sidewall having a first groove, said second sidewall having a second groove, said first sidewall has a chamfered surface that tapers into said first groove;
- a head which has a first tongue that can slide along said first groove and a second tongue that can slide along said second groove, said head can be assembled onto said ring from said top surface;
- a blade that is coupled to said head;
- and,
- a drive assembly that can move said head relative to said ring and said blade relative to said head.
