20120079701 | Method and apparatus for mounting a sheath onto the distal end of a surgical shaft instrument - A method for mounting a sheath onto the distal end of a surgical shaft instrument, in particular the tool tip of a dilation instrument. The method makes handling easy and allows the sheath to be fastened on the instrument in a rapid manner sparing of material, characterized by these steps: a) fastening the sheath on an apparatus for mounting a sheath onto the distal end of a surgical shaft instrument; b) radially widening at least the proximal end of the sheath and inserting the distal end of the surgical shaft instrument into the widened sheath c) transferring the sheath from the apparatus to the distal end of the surgical shaft instrument; and d) removing the distal end of the surgical shaft instrument from the apparatus. The invention also relates to an apparatus to perform this method. | 04-05-2012 |
20130158467 | Handle for a Medical Instrument - A handle for a medical instrument having a handle housing and a connection adapter for hose and/or tube connections, which can be inserted into the handle housing. The connection adapter can be inserted fluid-tight into a corresponding support recess of the handle housing by at least one connection support and such that a surrounding ring groove for inserting a sealing element is positioned on the at least one connection support. It is proposed that at least two surrounding ring grooves, mounted one behind the other, should be configured on the connection support in the axial direction of the at least one connection support, such that the connection support has a constant outer diameter in the area of the at least two ring grooves and such that a sealing element, is positioned at least in the first ring groove, looking from the free end of the connection support. | 06-20-2013 |
20130302084 | Tool for a medical instrument - A tool for a distal end or on a distal end of a shaft of a medical instrument includes a basic body, a mouth part which is pivotable about a pivot axis in relation to the basic body, and a bearing which defines the pivot axis, wherein the bearing includes two axial pins which are spaced apart from one another, each with a radial surface which is rotationally symmetrical with respect to the pivot axis. | 11-14-2013 |
20130304041 | Handling device for a medical instrument - A handling device for a medical instrument includes a main body with a coupling for releasable mechanical connection to a proximal end of an outer shaft, a first actuation device movable relative to the main body, a second actuation device movable relative to the main body, a first coupling device coupling the first actuation device to a first transfer device for transferring at least a force or a torque, and a second coupling device coupling the second actuation device to a second transfer device for transferring at least a force or a torque. The coupling devices each have a decoupling position, in which the associated actuation device is decoupled from the associated transfer device. The decoupling positions of both coupling devices can only be reached when the outer shaft is not connected to the coupling on the main body in the manner provided for use of the medical instrument. | 11-14-2013 |
20130304063 | Micro-Invasive Medical Instrument - 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. | 11-14-2013 |
20130310814 | Medizinisches Instrument und Verfahren zum Zusammensetzen eines medizinischen Instruments - 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. | 11-21-2013 |
20130310865 | Unknown - A tool for a medical instrument includes an effecting device, a transmission rod, of which the distal end is coupled to the effecting device, for transferring at least either a force or a torque to the effecting device, and a cutting device, which, to cut tissue, is movable in a channel in the transmission rod and in the effecting device. To cut tissue, the cutting device is movable in a channel in the transmission rod and in the effecting device. | 11-21-2013 |
20140214011 | Medical Instrument - A medical instrument having a shank, at the proximal end of which a handle is arranged, wherein the shank is rotatable about its longitudinal axis and can be secured in various positions of rotation relative to the handle via a licking mechanism. In order for a medical instrument with a shank rotatable about its longitudinal axis to be designed in such a way that, while being easy to handle, it permits a large number of secure and positionally precise rotations of the shank with respect to the handle, the licking mechanism is designed as a latching mechanism which has a perforated disk with recesses and latching elements, wherein the latching elements and/or the perforated disk are spring-loaded relative to each other, and at least one of the latching elements engages in a corresponding recess of the perforated disk in order to fix the shank. | 07-31-2014 |
