Patent number: 8400312Abstract: An operation assisting system. When an operator manipulates an operation instrument to perform an operation for a joint surgery including a hip replacement, the operation assisting system provides the operator with information on the orientation of a bone such as a pelvis and an appropriate direction of the operation instrument relative to the bone to assist the operator so as to complete the operation in an easy and accurate manner, which ensures a high degree of operation accuracy and reduces the cost of the system.Type: GrantFiled: October 9, 2007Date of Patent: March 19, 2013Assignee: Saga UniversityInventors: Takao Hotokebuchi, Kenbu Teramoto, Masamori Shigematsu

Patent number: 8162995Abstract: A bone plate having a rear face and opposing front face, adapted to be abutted on a bone, and a through hole extending between the front and rear faces, and attached to a bone to be set by applying the bone plate to the bone, and by screwing a screw into the bone through the through hole. The bone plate has a blind first dimple provided in at least one of the faces thereof other than the rear face. One acute gripping tip of a pair of bone forceps may be abutted on the bone, with the other acute griping tip of the bone forceps being engaged in the first dimple. The first dimple is configured so as to converge from an opening portion thereof on the dimple-provided face toward a bottom portion thereof, whereby the other acute gripping tip of the bone forceps can slide toward the bottom portion.Type: GrantFiled: March 17, 2006Date of Patent: April 24, 2012Assignee: Saga UniversityInventors: Motoki Sonohata, Takao Hotokebuchi, Masaru Kitajima

Patent number: 7955394Abstract: The artificial knee joint includes a femoral component, a tibial tray and an insert plate fixed onto the top surface of the tibial tray. The femoral component includes a femoral articular surface and a cam that is provided on the rear end of the femoral articular surface and protrudes from the femoral articular surface, the insert plate includes a tibial articular surface that makes contact with the femoral articular surface and a cam-receiving slide surface that makes contact with the cam. When the knee is extended, the joint takes a first sliding state in which the femoral articular surface slides against the tibial articular surface. When the knee is bent at an angle in a range from 90 to 160 degrees, the joint shifts from the first sliding state to a second sliding state in which the cam slides on the cam-receiving slide surface.Type: GrantFiled: July 13, 2006Date of Patent: June 7, 2011Assignees: Saga University, Japan Medical Materials CorporationInventors: Takao Hotokebuchi, Yasuju Takano
