In addition, at least one second arrangement can be provided which configured to increase and/or decrease a size of the opening by a motion thereof in a first direction. Further, at least one third arrangement can be provided which can be coupled to the second arrangement(s), and configured to move at least in a second direction which is at least approximately parallel to the second direction. In particular, when the anatomical structure(s) is/are provided or inserted in the opening and is pressed on by the second arrangement(s), a first motion of the second arrangement(s) toward the anatomical structure(s) in the first direction is reduced and/or terminated while a second motion of the third arrangements) in the second direction either (i) remains at least approximately the same, and/or (ii) is reduced to a lesser extent than that of the first motion. | 2015-06-25 |
20150173786 | Rotable And Pivotable Medical Instrument - A medical instrument has a shaft, which has a distal end and a proximal end, with a jaw head which is arranged at the distal end and is pivotable out from the longitudinal axis of the shaft, wherein the jaw head has two jaw parts, of which at least one is pivotable, furthermore, with a first actuation element for pivoting the jaw head, and with a second actuation element for pivoting the pivotable jaw part, wherein the actuation elements are received in the shaft, and with control elements which are arranged at the proximal end of the shaft and are used for controlling the movement of the actuation elements. The actuation elements are arranged extending coaxially with respect to each other, and that the actuation elements are received in the shaft so as to be rotatable jointly about the shaft axis and to be rotatable relative to the shaft. | 2015-06-25 |
20150173787 | Medical Instrument With A Flexible Toothed Belt - A medical instrument has a shaft with a longitudinal axis, a jaw head on a distal end of the shaft having two jaw parts, at least one of the jaw parts being pivotable about a pivot axis extending transversely to the longitudinal axis, the pivotable jaw part having a wheel portion with toothing mounted about the pivot axis, at least one actuation element having a distal end portion with toothing that meshes with the toothing of the wheel portion such that movement of the actuation element along the longitudinal axis pivots the pivotable jaw part, control elements at a proximal end of the shaft controlling movement of the actuation element, said distal end portion with toothing is flexible, one of the jaws having a hollow space arranged distally to the pivot axis, wherein the distal end portion comes in or out of the hollow space when moving the actuation element. | 2015-06-25 |
20150173788 | MINIATURE SHREDDING TOOL FOR USE IN MEDICAL APPLICATIONS AND METHODS FOR MAKING - The present invention relates generally to the field of micro-scale or millimeter scale devices and to the use of multi-layer multi-material electrochemical fabrication methods for producing such devices with particular embodiments relate to shredding devices and more particularly to shredding devices for use in medical applications. In some embodiments, tissue removal devices are used in procedures to removal spinal tissue and in other embodiments, similar devices are used to remove thrombus from blood vessel. | 2015-06-25 |
20150173789 | SURGICAL INSTRUMENTS WITH ARTICULATABLE SHAFT ARRANGEMENTS - A surgical instrument that can comprise a surgical end effector that is configured to perform at least one surgical procedure upon application of at least one control motion thereto. The surgical instrument may further include an elongated shaft assembly that defines a longitudinal tool axis and is operably coupled to the surgical end effector. The elongated shaft assembly may operably support at least one control component and include a flexible articulation portion for facilitating articulation of the surgical end effector relative to the longitudinal tool axis. The flexible articulation portion may comprise a longitudinally-extending, elongated articulation spine that includes a plurality of ribs that extend from each lateral side of the articulation spine. Each rib may include at least one anti-twist feature for preventing the flexible articulation portion from twisting about the longitudinal tool axis during articulation of the surgical end effector. | 2015-06-25 |
