6 results about "Endoscopic resection" patented technology

This invention discloses a method and apparatus for endoscopic resection. The apparatus includes at least two components (including a puncture tip and an optional stop) and a coiled central portion connecting the at least two components. A first component is attached to one mucosal edge of the lesion, and a second component is attached to another mucosal edge of a catheter. Releasing the apparatus and allowing the central portion to coil pulls the first and second components together to contract and compress the lesion, thereby reducing the size of at least one lesion. A deployment catheter for releasing the apparatus onto the lesion includes an outer catheter and an inner catheter with a mechanism for delivering the resection device.

A medical device for facilitating a minimally invasive surgical procedure may include a housing and an arm. The housing may be configured for engagement around an outer circumferential surface of an endoscope and may include a first cavity. The arm may include at least one cutting surface and may be movably received within the first cavity. The arm may be configured to perform a first predetermined movement along at least a first plane at a predetermined frequency.

The present application belongs to the technical field of tumor diagnosis system, and particularly relates to a CLE combined with ME-NBI multi-modal endoscopic image early esophageal cancer grading and treatment decision system. The system comprises an image access module, an ME-NBI lesion coordinate establishment module, a CLE sampling point mapping module, an image evidence stratification module, a cross-modal feature recording module, an image grade determination module, an auxiliary path prompting module and a result output module. Based on the lesion outer edge line, the longest diameter axis and the like, the CLE sampling points are mapped to the corresponding coordinate positions, and the image quality grades and the like are generated. According to this, the lesion image grade label, the evidence credibility mark, the review prompt mark and the auxiliary path prompt label are outputted. The macroscopic endoscopic observation and the microscopic CLE sampling form a spatial corresponding relationship, the traceability of the early esophageal lesion grading result is improved, and the auxiliary basis for review sampling, additional biopsy, endoscopic resection or comprehensive treatment evaluation is provided.

The utility model discloses a digestive endoscopy resection specimen collecting device which is characterized in that an inlet connecting pipe and a discharge connecting pipe are arranged on the two sides of a collecting box respectively, an air guide plate is arranged in the collecting box and used for enabling a negative pressure suction route to be from the inlet connecting pipe to the discharge connecting pipe, and a collecting hopper is arranged at the bottom of the collecting box; the supporting frame is inserted into the collecting box, and sterile gauze is arranged in the supporting frame; and the specimen bottle is arranged below the collecting hopper. The inlet connecting pipe is connected with a suction pipe arranged in the digestive endoscope, the discharge connecting pipe is connected with a connecting port of a suction device, the suction pipe of the digestive endoscope sucks a specimen into the collecting box, and the specimen falls to the lower portion of the collecting box under the guiding effect of an air guide plate and enters a specimen bottle through a collecting hopper and a connecting nozzle. The collection of the specimens is completed, tedious specimen taking-out operation is avoided, manpower is saved, the external world is prevented from making contact with the specimens, and the probability that the specimens are damaged and polluted is reduced.

The application discloses a wire snare for use under a digestive endoscope, which comprises a snaring device and an operating assembly. The snaring device comprises a resin clamp, a spring, a connecting hole, a metal wire and a baffle. The spring is installed on the resin clamp. The resin clamp is provided with the connecting hole for fixing the metal wire. The end of the resin clamp is provided with the baffle. The operating assembly comprises a snaring device base, a resin clamp operating rod, a resin clamp loose clamp rod, a resin clamp operating rod handle and a metal wire operating handle. The device can make up for the shortage of the traditional snare. When the resin clamp is fixed to the intestinal wall mucosa, the other end of the metal wire is made to surround the polypus bottom through the metal wire operating handle. After being tightened, the metal wire connected with the resin clamp forms a closed loop. In the case of power supply, the polypus as large as possible or the polypus with a more tricky position can be removed under the endoscope. The device is convenient and fast, improves the operation efficiency and the safety of the operation of the patient.
