摘要:
A device for supporting at least one arm of an operating person during a surgical or medical operation comprises at least one supporting element for supporting the at least one arm of the operating person, the supporting element being arranged at a carrying structure for carrying the at least one supporting element. The carrying structure is configured such that the at least one supporting element can be lowered or raised for adjusting the height of the operating person's arm. The carrying structure comprises a control system which comprises a hydraulic circuit for lowering or raising the at least one supporting element.

The carrying structure comprises at least one carrying arm, which is pivotable about at least one at least approximately horizontal pivot axis such that pivoting of the carrying arm raises or lowers the at least one supporting element. The carrying structure further comprises a mechanical control system acting on the pivotability of the at least one carrying arm in the upward direction differently from the downward direction.

A device for supporting at least one arm of an operating person during a surgical or medical operation comprises at least one supporting element for supporting the at least one arm of the operating person, the supporting element being arranged at a carrying structure for carrying the at least one supporting element. The carrying structure is configured such that the at least one supporting element can be lowered or raised for adjusting the height of the operating person's arm. The carrying structure comprises a control mechanism for lowering or raising the at least one supporting element, wherein the control mechanism includes a force load switch for activating the lowering or raising of the at least one supporting element, wherein the force load switch activates the lowering or raising of the at least one supporting element upon detecting compressive and/or tensile forces or motions acting via the at least one supporting element on the force load switch.

The invention relates to a medical instrument for removing objects from narrow passages, which instrument has a shaft on whose distal end a hook-shaped curvature is configured. In order to produce a medical instrument that is easy to operate and ensures reliable removal of objects even in cramped space conditions, it is proposed with the invention that the distal end of the shaft can be converted between an essentially linear form and a form that has a hook-shaped curvature.

The invention relates to a medical gripping and/or cutting instrument with a shaft having on its distal end a tool consisting of at least two jaw members and on its proximal end a handle consisting of at least two gripping members. For opening and closing, at least one jaw member of the tool can be displaced with respect to the other jaw member of the tool by means of a rotatably configured gripping member of the handle. To produce a medical gripping and/or cutting instrument that allows operation that relieves the hand along with optimized action, it is proposed with the invention that at least one portion of at least one gripping member of the handle can rotate around the longitudinal axis of this gripping member.

The invention relates to a medical gripping and/or cutting instrument with an instrument shaft (1), with a handle (3) that can be fixed movably on the instrument shaft (1), and with a tool (2) mounted on the distal end of the instrument shaft (1) and consisting of two jaw member (2a, 2b), where at least one jaw member (2a or 2b) of the tool (2) can move in relation to the other jaw member (2b or 2a). In order to provide a medical instrument that, along with good cleaning properties and compact structure, also ensures simple and safe operation, the invention proposes that the handle (3) should include a coupling mechanism both to fix the handle (3) to the instrument shaft (1) and also to operate the at least one movable jaw member (2a or 2b) of the tool (2).

A downhole tool includes a device to be activated by electrical energy and a micro-switch that includes conductors and an element between the first and second conductors selected from the group consisting of: a dielectric element capable of being modulated to provide a conductive path in response to receipt of electrical energy; and an element moveable in response to application of an electrical energy. The micro-switch may be formed of microelectromechanical system (MEMS) technology or microelectronics technology.

A system for hanging objects from a mounting surface is presented. In one or more arrangements, the system includes a mounting rail and one or more hanging members configured to attach to the mounting rail and facilitate hanging of objects therefrom. The mounting rail includes a channel member that provides a channel having a downward facing open end. The hanging members are configured to be inserted into and held within the channel of the channel member. The hanging members each have a body configured to hang or hold one or more objects. Hanging members have a head portion configured to be inserted into and held within the channel. The hanging member also has a neck portion. When the head portion is held within the channel, the neck portion extends through the open end of the channel and connects the head portion to the body of the hanging member.
