Abstract: A medical tubular shaft instrument having a tube and a force transmission element extending lengthwise through the tube. The tube includes a jaw member arrangement on a distal end, which is coupled with the force transmission element and actuated by sliding the force transmission element along the tube. The tube includes a handpiece on a proximal end. The force transmission element, over part of its length, has a smaller outer diameter than the inner diameter of the tube to configure a ring-shaped flushing canal, and, one section along its length, it is centered in the tube in this section. The force transmission element includes precisely one section in which it is centered in the tube, and the section is in the vicinity of the distal end of the force transmission element and is perpendicular to its longitudinal axis by reshaping the force transmission element.

Abstract: A tool, which is detachably coupleable with a shaft for a micro-invasive surgical instrument, includes an articulated device on which a jaw member or other active device is affixed, a connecting component that is rotatably connected with the articulated device and that includes a coupling device for detachable coupling with a distal end of a shaft, a transmission rod to transmit at least either a force or torque from one proximal end of a shaft detachably coupled with the tool to the jaw member or other active device, and a locking device that is coupled with the transmission rod in such a way that the locking device can be rotated with respect to the transmission rod but not slid axially, so that the locking device is mounted in the connecting component in such a way that it can be axially slid but not rotated in relation to the connecting component.

Abstract: A medical instrument with a hollow shaft and a handle mounted on the proximal end of the shaft, such that the shaft can be rotated around its longitudinal axis by a power drive, and such that the power drive is configured as an adjusting wheel that can both be rotated around the longitudinal axis of the shaft and also moved in the longitudinal direction of the shaft. To provide a medical instrument whose power drive makes simple and secure operation of the shaft rotation possible, the power drive can be actuated in every working position in one-handed operation, independently of any other actuation of the handle.

Abstract: The invention relates to a bipolar coagulation instrument having a hollow shaft configured as a suction and/or flushing tube and having two electrodes that are electrically insulated with respect to one another and extend beyond the distal end of the shaft. To provide a bipolar coagulation instrument that is both of simple structure and ensures an effective suction/flushing capacity, it is proposed with the invention that the hollow shaft should consist of two electrically conductive tubes coaxially mounted on one another that are electrically insulated with respect to one another and from the outside, so that the tubes constitute the electrodes.

Abstract: A medical instrument has a shaft. The shaft has an outer shaft and an inner shaft. The outer shaft encloses the inner shaft. The medical instrument further has an actuator for rotating the inner shaft about a longitudinal axis relative to the outer shaft, arranged at a proximal end region of the shaft. The medical instrument has at least two tappet elements for transferring a rotary movement of the actuator to the inner shaft, which are engaged interchangeably with the inner shaft for transferring the rotary movement of the actuator to the inner shaft. The tappet elements reach through peripherally limited openings in a proximal end region of the outer shaft, which openings are offset with respect to one another in the longitudinal direction.

A second force transmission element is designed to transmit a second maximum force greater than the first maximum force, the second force transmission element has a second connection element. The first grip has a coupling device for selectively force-fitting to the first or second connection elements of the first or second force transmission elements to the movable grip part. The first connection element has a first cross-section. The second connection element has a second cross-section different from the first cross-section. The coupling device has a first seat designed for a force-fit connection to the first connection element and a second seat designed for a force-fit connection to the second connection element.

Abstract: The balloon trepan is used in minimal invasive surgery in order to create or maintain the area required for an operation by dilation of tissue or dissection of layers of tissue. The connection between the balloon and the sleeve of the trepan must be easily and securely produced without enlarging the outer diameter of the balloon trepan. The balloon must be secured against slipping and must be able to resist pressure during inflation. The balloon surrounding the distal end of the trepan is pressed against a peripheral step formed on the sleeve of the trepan by a clamping element in order to fix it to the sleeve of the trepan. The clamping element is displaced by rotation of at least one part of the clamping element about a longitudinal axis of the sleeve of the trepan in a longitudinal direction in relation to the said sleeve.
