Abstract:
A sealing means for sealing an introduction facility for a medical instrument includes a first sealing membrane of an elastic material with a first slit and a second sealing membrane of an elastic material with a second slit. The first sealing membrane and the second sealing membrane abut laminarily on each other. The first sealing membrane and the second sealing membrane are arranged such that the first slit and the second slit are not parallel with each other. Each of the first slit and the second slit is unbranched.
Abstract:
A medical instrument includes a shaft whose distal end is bendable. Arranged at the proximal end of the shaft there is a handle on which a bend control mechanism for controlling the bending movement is arranged. The bend control mechanism has a pivotable control element. The pivotable control element runs over a friction element, and an actuating element is provided via which the friction element can be brought out of a locking engagement with the control element.
Abstract:
An endoscope having an endoscope shaft, with a distal shaft portion, a central shaft portion and a proximal shaft portion, and a light admission face at the distal shaft portion. The cross section of the central shaft portion is smaller than the cross section of the distal shaft portion and smaller than the cross section of the proximal shaft portion.
Abstract:
A medical instrument includes a shaft which is connected at the proximal end to a handle, and it also includes an insert which is guided along the shaft and which is connected at the proximal end to a movable grip part of the handle. At its distal end, the insert has a tool which can be actuated by pivoting of the grip part. A lock is also provided which can be brought into locking engagement with the movable grip part. To cancel the lock function, a detent is provided which can be brought between lock and movable grip part, such that the lock function can be cancelled by the detent.
Abstract:
A medical instrument includes an outer shaft, a manipulation device at the proximal end of the outer shaft, a tool at the distal end of the outer shaft, with a first effecting device for a first function and a second effecting device for a second function, a first transmission device in the outer shaft for transmitting at least either a force or a torque for controlling the first effecting device, and a second transmission device in the outer shaft for transmitting at least either a force or a torque for controlling the second effecting device. The outer shaft is at least either curved or able to be curved or has a pivot joint. The first transmission device and the second transmission device are each designed to be flexible at least in sections.
Abstract:
A medical instrument includes an outer shaft, a transmitting device arranged for transferring at least a force or torque and a tool having a coupling device for detachable mechanical connection of the tool and a coupling device on the distal end of the outer shaft and having a transferring coupling device for the detachable mechanical connection of the tool and a tool coupling device on the distal end of the transmitting device. The mechanical connection of the tool coupling device on the outer shaft and the outer shaft coupling device buildable by moving the outer shaft in relation to the tool in a first direction. The mechanical connection of the tool and transfer coupling devices on the transmitting device and device buildable by moving the transmitting device in relation to the tool in a second direction. The first direction opposite to the second direction.
