Electrosurgical instrument

A system and method are disclosed for removing a uterus using a fluid enclosure inserted in the peritoneal cavity of a patient so as to enclose the uterus. The fluid enclosure includes a distal open end surrounded by an adjustable loop, that can be tightened, a first proximal opening for inserting an electrosurgical instrument into the fluid enclosure, and a second proximal opening for inserting an endoscope. The loop is either a resilient band extending around the edge of the distal open end or a drawstring type of arrangement that can be tightened and released. The fluid enclosure is partially inserted into the peritoneal cavity of a patient in a deflated condition and then manipulated within the peritoneal cavity over the body and fundus of the uterus to the level of the uterocervical junction. The loop is tightened around the uterocervical junction, after which the enclosure is inflated using a conductive fluid. The loop forms a pressure seal against the uterocervical junction to contain the conductive fluid used to fill the fluid enclosure. Endoscopically inserted into the fluid enclosure is an electrosurgical instrument that is manipulated to vaporize and morcellate the fundus and body of the uterus. The fundus and body tissue that is vaporized and morcellated is then removed from the fluid enclosure through the shaft of the instrument, which includes a hollow interior that is connected to a suction pump The fundus and body are removed after the uterus has been disconnected from the tissue surrounding uterus.

Methods, compositions and systems for local delivery of drugs

Implantable medical device eluting drug locally and in prolonged period is provided, including several types of such a device, the treatment modes of implementation and methods of implantation. The device comprising of polymeric substrate, such as a matrix for example, that is used as the device body, and drugs, and in some cases additional scaffolding materials, such as metals or additional polymers, and materials to enhance visibility and imaging. The selection of drug is based on the advantageous of releasing drug locally and in prolonged period, where drug is released directly to the extracellular matrix (ECM) of the diseased area such as tumor, inflammation, degeneration or for symptomatic objectives, or to injured smooth muscle cells, or for prevention. One kind of drug is the gene silencing drugs based on RNA interference (RNAi), including but not limited to si RNA, sh RNA, or antisense RNA/DNA, ribozyme and nucleoside analogs. The modes of implantation in some embodiments are existing implantation procedures that are developed and used today for other treatments, including brachytherapy and needle biopsy. In such cases the dimensions of the new implant described in this invention are similar to the original implant. Typically a few devices are implanted during the same treatment procedure.

System and method for replicating files in a computer network

ActiveUS20050177603A1Facilitate substantially real-time synchronizationEfficient use ofError detection/correctionSpecial data processing applicationsReal-time dataTerm memory
A system and method for performing real-time replication of data across a network is provided. A mirroring engine receives a write request from a host application operating on a source computer. The mirroring engine compares data in the write request with corresponding data stored in memory. If data in the write request differs from stored data, the mirroring engine processes the write request. Processing involves computing a data signature across data in the write request and associating the signature with a transaction number and a status byte. The transaction number is used to uniquely identify the data signature and can be used to ensure that the signature is properly handled if it is received, for example, out of order. The status byte contains information used for handling the data signature and transaction number as well as information identifying how the data signature was computed. In an embodiment, the status byte may contain a bit for identifying if the data signature was computed across an entire block of data or if the signature was computed over only a portion of a data block, such as for example, only data bytes that have changed as compared with those in the stored data. Processing may further include compressing and encrypting the data signature, transaction number and status byte prior to transmission over a network. Embodiments may further employ a meta-file for storing data signatures, transaction numbers, status bytes, and other information useful for performing real-time data replication over a network.

Mobility tracking method and user location tracking device

A user location tracking method allows a topology of a travel path taken by a user to be estimated without the use of location information such as GPS coordinates, so that a travel range of the user who only carries a small-sized terminal can be tracked at all times. The mobility tracking method is employed by a user location tracking device which uses radio waves sent from wireless devices distributed ubiquitously, the mobility tracking method including: detecting wireless device information identifying wireless devices out of the ubiquitously available wireless devices when the radio waves are received at a location where the user location tracking device is situated; storing the detected wireless device information as historical data; and estimating a topology, as the user location tracking device is moving, that shows a positional relation and a connection relation of a travel path taken by the user location tracking device, the estimation being performed on the basis that the location of the user location tracking device has deviated from a previously tracked path which has been traveled before by the user location tracking device and that the location of the user location tracking device has returned to the previously tracked path, using the stored historical data.

Hydraulic reversing mechanism

The invention discloses a hydraulic reversing mechanism. The hydraulic reversing mechanism comprises an upper joint, a center shaft, a guide ring, an upper shell, a guide pin, a connection nipple, a compression spring, a lower shell, a limiting sleeve and a lower joint, wherein the upper joint is connected with the center shaft, the guide ring is arranged between the upper joint and the upper shell, and the upper shell, the connection nipple, the lower shell and the lower joint can be slidably arranged on the outer side of the center shaft. The guide pin is arranged on the upper shell, a guidegroove is formed in the portion, corresponding to the guide pin, of the center shaft, the guide pin can rotate in the guide groove, a compression cavity is defined by the connection nipple, the lowershell, the lower joint and the center shaft, and the compression spring and the limiting sleeve are arranged in the compression cavity. The hydraulic reversing mechanism has the benefits that the hydraulic reversing mechanism can be used for rotational reversing of a sand washing tool, the washing operation is more sufficient, no atomization is generated, and the washing capacity is ensured. According to the hydraulic reversing mechanism, reversing is achieved under the hydraulic action, the structure is simple, and convenience is brought to installation, disassembly and maintenance. The large-discharge-capacity cleaning work can be met, and rotary jetting to the washing tool can be achieved.
