The invention provides a collection device for excised specimens under a digestive endoscope, and relates to the technical field of specimen collection. The collection device for the excised specimensunder the digestive endoscope comprises a storage tank and a clamping device, the storage tank is internally provided with the clamping device, the clamping device comprises long rods, one ends of the long rods are fixedly connected with the inner wall of the storage tank, the long rods are uniformly distributed on the inner wall of the storage tank, a clamping plate is fixedly connected to the end, away from the inner wall of the storage tank, of the long rod, the clamping plate is in an arc shape, a limiting plate is slidably connected to the side, away from the long rod, of the clamping plate, the limiting plate is in a U shape, and a collecting pipe is slidably connected to the sides, close to each other, of the clamping plate and the limiting plate. According to the collection device, the problems that a traditional storage device is complex in specimen fixing mode, when excised specimens of multiple patients are stored, the storage device needs to be repeatedly opened to store the specimens, and the collection efficiency of the specimens can be greatly reduced through the complex fixing mode are solved.
