Abstract
A surgical attachment instrument and method according to which a housing is adapted to be coupled to a motor. A tubular member is coupled to the housing so that an end of the tubular member extends from the housing at a predetermined distance. The predetermined distance may be selectively adjusted by a repeatable increment.
Claims60
A surgical attachment instrument comprising:
- a housing adapted to be coupled to a motor;
- a tubular member coupled to the housing so that an end of the tubular member extends from the housing at a predetermined distance;
- and
- means for selectively adjusting the predetermined distance by a repeatable increment.
A surgical attachment instrument comprising:
- a housing adapted to be coupled to a motor;
- a tubular member;
- a coupling connecting the tubular member and the housing;
- and
- an arcuate member concentrically disposed between the coupling and the housing, with at least a portion of the arcuate member extending in a channel formed in the housing to provide a resistance to disengagement of the coupling from the housing.
A surgical attachment instrument comprising:
- a shaft adapted to be coupled to a motor;
- at least two adjacent bearing assemblies for supporting the shaft;
- a spacer extending between the two adjacent bearing assemblies;
- and
- a tubular member extending around the spacer and the bearing assemblies and lockingly engaging the spacer.
A method of assembling a surgical attachment instrument, comprising:
- providing a housing adapted to be coupled to a motor;
- connecting a tubular member to the housing so that an end of the tubular member extends from the housing at a predetermined distance;
- and
- selectively adjusting the predetermined distance by a repeatable increment.
A method of assembling a surgical attachment instrument, comprising:
- engaging an arcuate member with a coupling;
- engaging the coupling with a housing adapted to be connected to a motor;
- forcing at least a portion of the arcuate member into a channel formed in the housing;
- and
- connecting a tubular member to the coupling.
A method of assembling a surgical attachment instrument, comprising:
- providing a housing adapted to be coupled to a motor;
- connecting a tubular member to the housing;
- and
- lockingly engaging the tubular member with a spacer extending between two adjacent bearing assemblies in the tubular member.
