  • Patent number: 11970727
    Abstract: The present disclosure discloses a pathogenic microorganism sample collection and preservation device with a protection function, including a sampler and a preservation container; the sampler and the preservation container are both packaged by independent aseptic packaging bags. The sampler includes a sample collection mechanism, a holding mechanism, and a protection mechanism arranged between the sample collection mechanism and the holding mechanism. Before sample collection, the preservation container is sealed by an assorted sealing cover. The sample collection and preservation device of the present disclosure is convenient for holding and flexible adjustment of a sample collection angle. The protection mechanism between the holding mechanism and the sample collection mechanism plays a role of shielding, thus avoiding the problem of cross contamination.

  • Patent number: 11596433
    Abstract: The invention discloses an integrated tumor resection instrument and a simulation training system. The resection device comprises an imaging system, a minimally invasive incision, a processor, an operating device, a resection executing mechanism and a positioning control device. The operating device is connected to the input end of the processor, the resection actuating mechanism is provided with a resecting driver, and the positioning control device and the resecting driver are both connected to the output end of the processor; the simulation training system comprises the steps of designing a manikin; arranging the imaging system; integrated resection. The resection device can resect the whole tumor along the edge of the tumor, thereby avoiding the incomplete resection and even tumor recurrent caused by crushing in the process of resecting the tumor. The simulation training system can train an operator to quickly master the resection skill and operation of various positions.
