Publication number: 20210298765Abstract: A corrugated sawblade includes a body extending from a proximal end to a distal end and a cutting element coupled to the distal end of the body. The body is corrugated such that the body forms a wavy pattern defining ridges creating a series of peaks and valleys along the body. The corrugated body reduces the surface area of the sawblade contacting surrounding surfaces such as a cutting guide and the interior of the bone through which the blade is cutting. The decreased surface area in contact reduces friction and therefore reduces the amount of heat generated by the oscillating motion of the blade, reducing the likelihood of osteonecrosis. The cutting surface coupled to the body has a rectangular cross section for producing a planar cut.Type: ApplicationFiled: March 23, 2021Publication date: September 30, 2021Inventor: Carlos E.

Publication number: 20210298804Abstract: In one aspect, a bone plate system is provided that includes a bone plate body having a throughbore and a bone screw. The bone plate system includes a slider slidably connected to the bone plate body to slide between a clearance position wherein the slider permits a bone screw head portion to be advanced into the throughbore and seated against the bone plate body and an interference position wherein the slider inhibits bone screw back out from the throughbore. The bone plate system includes a resilient pin and the slider has a surface configured to deflect the resilient pin as the bone screw head portion shifts the slider from the interference position toward the clearance position. The deflected resilient pin urges the slider from the clearance position toward the interference position upon the bone anchor head portion seating against the bone plate body in the throughbore.Type: ApplicationFiled: March 24, 2021Publication date: September 30, 2021Inventors: Scott J.

Publication number: 20210298811Abstract: An electrosurgical generator supplies, during operation, a high-frequency alternating current to an electrosurgical instrument for plasma cutting of body tissue. The electrosurgical generator has outputs for connecting an electrosurgical instrument to supply an electrosurgical instrument connected to the outputs with a high-frequency alternating current, and for determining the impedance of a load connected to the outputs. The electrosurgical generator features impedance and voltage measuring units as well as an output voltage control unit. The output voltage control unit is designed to control the AC output voltage depending on a maximum output voltage value that is set during operation depending on an output value of the impedance measuring unit and/or depending on an output value of the voltage measuring unit, such that the maximum output voltage value predefines a lower AC output voltage during a vaporization phase than during an ignition phase occurring subsequently to the vaporization phase.Type: ApplicationFiled: March 29, 2021Publication date: September 30, 2021Applicant: OLYMPUS WINTER & IBE GMBHInventors: Jelle DIJKSTRA, Veronika HANDRICK, Andreas KARRASCH, Frank BREITSPRECHER
