Abstract

The application discloses an in-vivo tissue isolation device, and relates to the field of medical devices; the device comprises a control assembly and a tip assembly; the control assembly has an internal hollow outer sleeve; one end of the outer sleeve is provided with a release switch, and the other end can enter the human body and is fixed at a set position; the tip assembly is movably connected to the end of the outer sleeve away from the release switch; the release switch can control the tip assembly to open or close; after the tip assembly is opened, the position of the opened tip assembly is manually adjusted, and one end of the opened tip assembly is fixed on the skin; then, after the in-vivo tissue is manually lifted by a doctor, the opened tip assembly is used to isolate the in-vivo tissue from a surgical area. The in-vivo tissue isolation device can effectively isolate the in-vivo tissue, expose a surgical field, and reduce the risk of surgery.
