Abstract
A first trocar as an medical apparatus includes an insertion hole having a projection opening for leading out a biopsy forceps into a body of a subject, a lid body for blocking the projection opening of the insertion hole, and a cooling sheet for cryogenically cooling a biopsy portion arranged in the vicinity of the lid body in a state where the biopsy forceps is stored in the insertion hole, and is capable of easily harvesting a living tissue while retaining morphological change of tissues in a living body under various hemodynamics.
Claims12
A medical apparatus comprising:
- a biopsy treatment instrument insertion path through which a biopsy treatment instrument for performing a biopsy on a predetermined region in a body of a subject is inserted, the biopsy treatment instrument insertion path including a projection opening for leading out the biopsy treatment instrument into the body of the subject;
- a blockage body for blocking the projection opening;
- and
- a cooling member for cryogenically cooling a biopsy portion of the biopsy treatment instrument arranged in the vicinity of the blockage body in a state where the biopsy treatment instrument is stored in the biopsy treatment instrument insertion path.
A medical apparatus comprising:
- a biopsy treatment instrument to be introduced into a body of a subject, for performing a biopsy on a predetermined region;
- and
- a medical instrument including a biopsy treatment instrument insertion path and a projection opening, for leading out the biopsy treatment instrument into the body of the subject, wherein
- the medical instrument includes:
- a blockage body for blocking the projection opening;
- and
- a cooling member for cryogenically cooling a biopsy portion of the biopsy treatment instrument inserted in the biopsy treatment instrument insertion path.
A living tissue freezing and harvesting apparatus comprising:
- a storing portion for storing biopsy treatment instrument for performing a biopsy on a predetermined region in a body of a subject, the storing portion including a projection opening for leading out a biopsy portion of the biopsy treatment instrument into the body of the subject;
- a blockage body for blocking the projection opening provided to the storing portion;
- and
- a cooling member for cryogenically cooling the biopsy portion of the biopsy treatment instrument stored in the storing portion.
