Patent number: 6591698Abstract: A surgical instrument (12) includes a tool for screwing in a surgical implant or for cutting a thread in human bone tissue with thread tap. Also included is a unit (2) for supplying power and controlling the speed of an electric motor included in the tool, for example a d.c. motor (1). Detection members (7, 8) transmit signals (i1), dependent on the torque of the tool, to display members which comprise a computer unit (9) with screen (10). Displayed on the screen is a curve which shows the torque in relation to the torsional angle position. A curve or curves displayed in this way form(s) the basis for assessing the quality of the implant or of the bone tissue.Type: GrantFiled: July 21, 1999Date of Patent: July 15, 2003Assignee: Nobel Biocare ABInventors: Lennart Carlsson, Anders Petersson

Patent number: 6547565Abstract: An instrument is connected to a driving-in tool or drilling tool for elements on or in the form of an implant or drill for dentine. The tool includes an electric motor, the torque of which can be sensed, and which can be controlled by a control unit. A display unit is arranged so as to partly or fully display a curve representing the driving-in function performed. A tightening function is determined by a scale based on the slope of the curve, wherein a flatter slope represents a lower quality function and a steeper slope represents a higher quality function. A frictional resistance which exists for an element during the driving-in of the element can be determined in order to allow secure locking (preload) of the element by tension in the material of the element. A torque-time curve can be used assess the bone quality of bone being implanted or drilled.Type: GrantFiled: March 19, 2001Date of Patent: April 15, 2003Assignee: Nobel Biocare AB (publ)Inventors: Andrew Dawood, Anders Petersson
