Patent number: 9381003Abstract: The present disclosure generally pertains to a digital controller for surgical handpieces. The controller is programmable and configurable by software which may be used with a variety of types of handpieces. The controller is equipped with environmental sensors that detect pressure, humidity and temperature, and operational sensors that detect the angle and placement of the rotor of a motor. These sensors provide data used for testing and evaluating the function of the handpiece. A filter program is provided which removes electronic noise from collected data. The controller includes an electronic memory writer and reader to download firmware, control parameters for handpiece operation and read logged data from sensors to determine motor function. The sensor includes a hermetic enclosure constructed from a heat conducting material and that is non-ferromagnetic to allow communication between the trigger and controller.Type: GrantFiled: March 22, 2013Date of Patent: July 5, 2016Assignee: Integrated Medical Systems International, Inc.Inventors: Marius Todor, Peter Pal Bodor, Shusheng Ye

Patent number: 9161761Abstract: An instrument set and related method for preparing a proximal tibia during a bi-cruciate retaining procedure are disclosed. The instrument set can include a tibial resection block, a cut guide, and a locking arm. The tibial resection block can be configured to be fixed to an anterior portion of the proximal tibia. The tibial resection block can define a slot that extends in a medial-lateral direction when the tibial resection block is fixed to the proximal tibia. The cut guide can have a body, a medial arm, and a lateral arm. A medial cut slot can be defined between the body and the medial arm. A lateral cut slot can be defined between the body and the lateral arm. The cut guide can further comprise a tongue extending therefrom. The tongue can be configured to be received by and slidably translate along the slot of the tibial resection block.Type: GrantFiled: May 14, 2012Date of Patent: October 20, 2015Assignee: Biomet Manufacturing, LLCInventors: Robert Metzger, Nathan Belcher, Audra C. Watson, Bradley Durcholz, Joshua Catanzarite
