Patent number: 10478197Abstract: An orthopedic bone cutter for cutting bone and tissue is described. The orthopedic bone cutter comprises a cutting shell and a cutting insert that resides within an opening that extends through the apex region of the shell. A pin and slot mechanism positioned within the shell interior provides for independent axial and rotational movement of the insert within the shell. The shell comprises a partially hemispherical structure having a plurality outwardly extending and spaced apart shell cutting teeth. The insert comprises an annular sidewall that meets an end wall having a plurality of outwardly extending and spaced apart insert teeth. With the insert at a retracted position within the shell, the bone cutter is rotated in a first direction to cause the shell cutting teeth to cut, for example, an acetabular roof and labrum. Then, rotation of the shell in a second opposite direction causes the shell to stop cutting, but provides for the insert to extend outwardly to cut the acetabular floor and fossa.Type: GrantFiled: December 12, 2016Date of Patent: November 19, 2019Assignee: VIANT AS&O HOLDINGS, LLCInventor: Gary C.

Patent number: 10274021Abstract: A torque limiting tool comprises a two stage torque limiting mechanism that resides within a housing. The torque limiting mechanism comprises a shank positioned through a gear, a plate, and a bias member. The plate is constructed having at least one post and at least one tooth providing a ramp surface that extends outwardly from a plate surface. The gear is constructed having at least one recess providing at least one inclined surface that resides part-way within the thickness of the gear. The gear and plate are positioned in opposition so that the at least one tooth and extending post are received within or detachably mated to the opposing recess and through-bore. Torque is transferred therebetween the plate and gear when the ramped teeth and extending posts mate with the respective recess and through-bore. A first torque limit is exceeded when the post breaks free from the through-bore. A second, lesser torque limit is exceeded when the ramped teeth release from their mated recess.Type: GrantFiled: April 18, 2016Date of Patent: April 30, 2019Assignee: VIANT AS&O HOLDING, LLCInventors: Gary C.
