초록 ▼

A surgical cutting device having a powered handpiece adapted to receive a cutting blade. The cutting blade is locked to the drive shaft by a locking ball holding member which is locked in place by a cylindrical cam ring which urges the balls of the locking device into corresponding notches in the blade. A second locking ball holding member is provided on the housing of the handpiece to lock the cylindrical cam ring itself. A blade guard extends from the cylindrical cam ring to produce a surgical cutting device having an improved safety feature which prevents its operation without the guard in proper position.

대표청구항 ▼

A surgical saw system comprising: an elongated surgical blade having a proximal end, a distal end and at least one notch detent at the proximal end; a housing having an opening for receiving said surgical blade; a drive shaft having an end adjacent said opening; means for driving said drive shaft; blade receiving means at the end of said drive shaft for receiving said surgical blade, said blade receiving means comprising a first locking-ball retaining means having at least one ball situated on said drive shaft adjacent said end thereof for engaging said at least one notch at said proximal end of said surgical blade; a first, unitary cylindrical cam ring means for cooperative engagement with said first locking-ball retaining means, said first, unitary cylindrical cam ring means comprising an inner surface for urging said at least one ball of said first locking-ball retaining means into said at least one notch of said surgical blade, and an outer surface provided with an annular groove; cam ring receiving means for receiving said first, unitary cylindrical cam ring means, said cam ring receiving means comprising a second locking-ball retaining means having at least one ball situated on said housing for engaging said annular groove; a second cylindrical cam ring means movably situated on said housing for cooperative engagement with said second locking-ball retaining means, said second cylindrical cam ring means comprising a collar having an inner surface for urging said at least one ball of said second locking-ball retaining means into said annular groove; and means to hold said second cylindrical cam ring means fixed to thereby hold said at least one ball of said second locking-ball retaining means in said annular groove.
