Patent number: 6818005Abstract: A surgical, tubular-shafted instrument comprises a shaft, an operating rod mounted for displacement in the shaft, a handle part for actuating the operating rod and a connector that detachably connects the handle part to the shaft. The shaft is secured in an axial direction in an inner sleeve of the handle by a locking member that is displaceable radially in the inner sleeve and dips into a recess of the shaft. The radial outward movement of the locking member is limited by a stop element that is displaced into a position releasing the radial outward movement of the locking member. A holding element fixes the stop element in a release position and can be acted upon by the shaft to release the stop element due to displacement of the shaft in the inner sleeve. The holding element is guided for displacement in the handle part outside the inner sleeve.Type: GrantFiled: January 22, 2002Date of Patent: November 16, 2004Assignee: Aesculap AG & Co.

Publication number: 20040181144Abstract: In order to be able to ascertain the position of the bone in the body without complicated procedures in a process for the preoperative determination of the positioning data of endoprosthetic parts of a central joint relative to the bones forming the central joint, a respective outer articular point is determined by way or movement of the bones about a respective outer joint which is located at the end of the two bones facing away from the central joint. An articular point is determined for each of the two bones in the area of the central joint, and a direction characteristic for each of these bones is determined by way of a straight-line connection of the two articular points obtained in this manner for the two bones. The orientation of the endoprosthetic parts relative to this characteristic direction is then determined. Apparatus for carrying out the process is also provided.Type: ApplicationFiled: March 19, 2004Publication date: September 16, 2004Applicant: AESCULAP AG & Co.
