An automatically releasing instrument holder includes a grip to be held by an operator for guiding an instrument, an actuator to be activated by the operator and a biasing device exerting a force. A clamp is moved by the actuator toward the instrument against the force of the biasing device and is moved by the biasing device away from the instrument upon releasing the actuator. A method for operating the instrument holder is also provided.

A tissue retractor includes a body having proximal and distal ends. The retractor also includes a retraction device having a head connected to the distal end of the body and defining two opposing openings, a connector movably disposed in the body, and two flexible needles of a shape memory material having a memory shape. The needles are fixedly connected to the connector for traveling through a respective one of the openings. The memory shape of the needles includes a portion with an arcuate shape. A one-handed actuation device is connected to the proximal end of the body and is operatively connected to the connector through the body. Upon actuation of the actuation device, the connector can be moved to selectively extend the needles out of the head and withdraw the needles into the head. Methods for using the tissue retractor, in particular for the treatment of Gastroesophageal Reflux Disease, are also provided.

A flexible endoscopic clip applier includes a flexible coil with a manual actuator coupled to one end and a jaw assembly coupled to the other end. A store of clips is arranged adjacent to the jaw assembly and a clip pusher is arranged adjacent to the store of clips. The actuator includes a lever for opening and closing the jaws, a knob for rotating the jaw assembly, and a crank for dispensing clips. The knob and the lever are coupled to a single control member which extends through the coil to a joiner where it is joined to a pair of pull wires coupled to the jaws. The crank is coupled to a second control member which is threaded along a distal portion. The threaded portion engages a threaded member near the pusher and is coupled to the pusher such that rotation of the threaded control member by the crank causes the pusher to be moved distally.

A tissue retractor includes a body having proximal and distal ends. The retractor also includes a retraction device having a head connected to the distal end of the body and defining two opposing openings, an actuator movably disposed in the head, and two substantially rigid needles each pivotably connected to the actuator for traveling through a respective one of the openings. The needles have an arcuate shape. A one-handed actuation device is connected to the proximal end of the body and is operatively connected to the actuator through the body. Upon actuation of the actuation device, the actuator moves to selectively extend the needles out of the head and withdraw the needles into the head. Methods for using the tissue retractor, in particular for the treatment of Gastroesophageal Reflux Disease, are also provided.

A surgical clip has a base portion and two generally parallel, spaced arms extending from the base portion and defining an opening therebetween. The arms terminate distally in fingers which are of reduced width and thickness relative to the arms and which are adapted to be bent towards and past each other. A transition section from each arm to the finger provides curved structures which extending away from each other and providing a wider mouth for the opening between the arms. The arms also have a proximal section with an undercut which helps in flexure of the arms. The base is an extended structure having a rounded proximal end with outwardly extending shoulders which are arranged to be engaged by the curved structures of the mouth of another clip.

The present embodiments provide methods, apparatuses, systems for use in encoding and/or formatting content, such as multimedia content. Some embodiments provide methods for use in encoding content. These methods receive source content, encode the source content producing encoded content, evaluate a first encoded segment of the encoded content relative to a plurality of buffer models, determine whether the first segment of encoded content is to be re-encoded relative to one or more of the plurality of buffer models based on the evaluation; and re-encode the first segment when it is determined that the first segment is to be re encoded.

An automated method for identifying confidential information may include inputting a search term based on a set of policy rules into a search engine, and causing the search engine to perform a search based on the search term. The method may also include analyzing search results obtained from the search engine against the policy rules to identify the search results containing confidential information.
摘要:
A rotatable surgical instrument for use alone or in conjunction with other instruments such as an endoscope. The instrument, having a proximal end and a distal end, includes a proximal actuator assembly, a distal end effector assembly having a surgical tool and a first rotational engagement member, a hollow member extending between the actuator and the end effector assembly, and a control member extending through the hollow member. The control member has a proximal end connected to the actuator assembly, a distal end connected to the end effector assembly, and a second rotational engagement member. In operation, actuation of the actuator assembly causes the control member to actuate the surgical tool, and the first engagement member engages the second engagement member to transmit torque applied to the control member to the end effector assembly.
