5 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 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.
