A drive system for controlling movement of an elongate member includes a base unit having a first rotatable knob and a second rotatable knob, a follower assembly including a follower slidably coupled to a guide rail, a longitudinal movement wire, and a rotational movement wire. The follower includes a longitudinal movement pulley, a rotational movement pulley, and an alignment element structured to receive an elongate member such that the elongate member is attachable thereto. The longitudinal movement wire operably couples the first rotatable knob to the longitudinal movement pulley such that rotation of the first knob drives the follower in a longitudinal direction along the guide rail. The rotational movement wire operably couples the second rotatable knob to the rotational movement pulley such that rotation of the second knob rotates the alignment element and attached elongate member.

A joint and a corresponding method of creating a precision-fit joint, including creating a mating surface on a first joint component so that the mating surface includes one or more interfering features, connecting a second joint component with the mating surface such that the interfering feature is compressed, and heating the mating surface above a glass transition temperature or melting temperature of the mating surface, or otherwise treating the surface, so as to induce flow of material from the interfering feature to a area of relatively low pressure between the first joint component and the second joint component.

Instrument (9) micro positioning device on the stereotactic system consists of the linear drive with the collet-chuck and the bracket (1) with the instrument (9) guide. The collet-chuck fixes and positions the instrument (9) with the collet (6a, 6'a) and associated taper-nut (7, T). The collet (6a) with the associated nut (7) is intended for clamping and positioning a single instrument, whilst the collet (6'a) with the associated taper-nut (71) is intended for the simultaneous securing and positioning of five instruments (9) or microelectrodes at a time. Through holes of the collet (6'a) are coaxial with bores of the central spacer as instrument positioning guide (9), where the sections of the collet (6'a) form and define the four through holes, which are symmetrical and evenly-spaced around the central through-hole.

The invention relates to a device for controlling corporeal structures, especially for introducing puncture needles or operation probes. Said device comprises a base plate (1), at least one base holder (2) applied to the base plate (1), and holding rods (3, 4) that are fixed to the base holder in a fixed manner and are used to hold and position a targeting device (10) for a medical instrument (8). The aim of the invention is to create one such device in such a way that it has a simple structure and can guide medical instruments in a variable and precise manner. To this end, the targeting device (10) is mounted on two adjustment arms (7) that can be respectively displaced in the X and/or Y plane, on the free ends of the holding rods (3, 4), by means of an actuating drive (6).

The present invention relates to an apparatus for treating a tennis elbow, including: an apparatus body, a fixing part which is arranged near an outer side of the apparatus body for fixably positioning the apparatus body with respect to its surroundings, a part which is arranged in or near the apparatus body and can be extended with respect to the apparatus body, a positioning device which is arranged in or near the apparatus body for positioning the extendable part with respect to the apparatus body and a holder which is exchangeably connected to the extendable part during use, including a holder part with penetration means attached thereto, in which the penetration means are arranged on the holder part in a pattern. The apparatus body or the extendable part is provided with a manipulating element which manipulates a feature of the holder in such a way during use that the holder is made unsuitable for re-use in the apparatus.

A system for moving an elongate medical device has at least one drive element for engaging and moving an elongate medical device. Various embodiments provide for moving the separate inner and outer elements of a telescoping medical device. Some systems also provide for the rotation of a rotatable distal element on a rotatable medical device or the rotation of extension element in a telescoping medical device.

The invention relates to a surgery assistance system for guiding a surgical instrument, especially a camera system (2) having an endoscope (3) depending on the manual actuation of at least one function key (T1 – T6) of an operating element (BE). Advantageously, the angle of inclination (w) of the surgical instrument (3) is determined with respect to the spatial axis (z) of the Cartesian patent coordinate system (PKS) extending through the trocar point (T) and the angle of inclination (w) so determined is compared with a predetermined set angle of inclination (w s ). When the determined angle of inclination (w) exceeds the set angle of inclination (w s ), the tip (S) of the surgical instrument (3) is guided on a semi-spherical surface (TK) which concentrically surrounds the trocar point (T) and which receives the tip (S) of the instrument (3), and when the determined angle of inclination (w) is below the set angle of inclination (w s ), the tip (S) of the surgical instrument (3) is guided along a tangent (TG) which extends through the tip (S) of the instrument (3) and which rests on the semi-spherical surface (TK).
摘要:
Medical apparatus is described including a fiducial component and a position sensor. The component is recognizable as at least a part of a fiducial when appearing in image data of a patient. The component is attachable to the patient. The sensor is attachable to the component at a predetermined location and orientation on the component or is capable of being positioned adjacent the fiducial component without attachment thereto at a predetermined location and orientation. A storage medium is described containing a program which instructs the computer to recognize a predetermined shape of each of at least one portion of a position sensor as at least a part of a real-world fiducial in image data of a patient. The position sensor is adapted to provide position data. Medical apparatus which includes the position sensor and the storage medium is also described.
摘要:
An injection delivery system for automatically injecting fluid into an injection site includes at least one support element and a carriage moveably mounted to the at least one support element so that the carriage can move linearly relative thereto. The carriage has a support structure for removably receiving and carrying a syringe assembly for movement with the carriage, and a carriage actuator is operable to cause such linear movement of the carriage. A plunger actuator is carried by the carriage so as to move with the carriage, and is adapted to be operably coupled to a syringe plunger for causing linear movement of the syringe plunger within a syringe barrel. The carriage actuator and plunger actuator include respective inputs for receiving movement instructions, and may be coupled to an electronic controller that provides such instructions.
