The invention discloses a plasma tissue dissociation knife, and relates to the technical field of medical instruments. In order to solve the problems that when an existing endoscopic surgery relates to a plurality of instruments, the instruments need to be frequently switched for surgical operation, and the surgical efficiency is reduced, the following technical scheme is provided: the endoscopic surgical instrument comprises a tool bit, a tool bar, a handle and a cable which are connected in sequence; the cutter head comprises a blade telescopic assembly arranged on the head portion, an endoscope guide tube and a cutter head telescopic control mechanism are arranged in the handle, and the cutter head telescopic control mechanism drives a blade in the blade telescopic assembly to stretch out and draw back through a transmission piece. The positive cable extends to the tool bit to be connected with the blade telescopic assembly, the negative steel pipe is connected with the negative cable, and double-frequency emitter cutting is formed at the blade; the suction channel arranged in the cutter bar is used for flushing the surgical field and sucking turbid liquid in the operation. Compared with a traditional cold instrument, cutting efficiency, bleeding amount control, clear surgical field, cutter bar size optimization, cutting flexibility, sealing performance, operation convenience and the like are remarkably improved.

This utility model discloses a wire EDM machine tool for steel sheets, comprising a machine body, a working fluid discharge pipe installed on one side of the machine body, the end of the working fluid discharge pipe being connected to one side of a filter cartridge, the other end of the filter cartridge being connected to one end of a transfer pipe, and the horizontal portion of the transfer pipe being connected to one side of the middle of a spherical tank; the transfer pipe, the outer wall of the bottom end of the transfer pipe being fixedly connected to the top of the inner wall of a separator mesh cylinder, the bottom end of the separator mesh cylinder being fixedly connected to the bottom of the inner wall of the spherical tank, and a bottom discharge pipe installed at the bottom of the spherical tank; the spherical tank, a safety plate being fixedly fixed to the upper part of the inner wall of the spherical tank, and an exhaust pipe being installed at the top of the spherical tank. This wire EDM machine tool for steel sheets adopts a novel structural design, which can filter and adsorb debris in the working fluid multiple times, ensuring the separation effect of debris from the working fluid. Furthermore, the filtration and adsorption can be easily disassembled, cleaned, and purified, enabling the entire device to stably process the working fluid for a long time.

The present invention provides a smart construction method and device based on data processing. Based on the positioning data of each user terminal, a user terminal that meets the enclosure detection conditions of the enclosure construction area is determined as a target terminal, and the enclosure construction area includes multiple detection devices; the motion trajectory of the target terminal is obtained, and the security detection data corresponding to the target terminal is determined according to the motion trajectory, and the security detection data includes a dynamic detection area and a detection time series; the corresponding detection device is controlled to perform intrusion detection on the target terminal based on the security detection data to obtain detection data; the detection data that meets the abnormal detection conditions is determined as abnormal data, and the monitoring equipment is controlled to collect data according to the abnormal data, and the warning data obtained is sent to the management terminal.

The present invention relates to a vision control lens and glasses, and belongs to the technical field of myopia glasses. The vision control lens comprises a lens body and a defocused microlens, wherein the defocused microlens covers the entire lens body, and two adjacent defocused microlenses are spaced apart; wherein the diameter of the defocused microlens is less than 1 mm, and the ratio of the spacing between two adjacent defocused microlenses to the diameter of the defocused microlens is (0-0.5):(0-1). The vision control lens covers the lens body with defocused microlenses, and utilizes the defocused microlenses to make the optical focus of the light passing through the lens body fall on the retina or in front of the retina, thereby avoiding the problem that the optical focus of a part of the lens body falls behind the retina, resulting in unclear vision.
