PROBLEM TO BE SOLVED: To provide a biopsy device which has a relatively simple structure, and which allows even a weak-handed person to easily perform charging operation.SOLUTION: In a biopsy device 10, a biopsy needle is locked in a charging position and shot to a projecting position by releasing the lock. In the biopsy device 10, an inner needle charging hole 12 and an outer needle charging hole 16 are formed. By an inner needle charging member 120 and an outer needle charging member 160 which are inserted into these holes from the outside, an inner needle slider or an outer needle slider can be slid to the charging position against the energizing force of a spring and locked therein. In addition, a charge device includes: a fixing part 100 for fixing the biopsy device 10; and a charging part 200 which holds the inner needle charging member 120 and the outer needle charging member 160 so that the members can respectively advance into and retreat from the inner needle charging hole 12 and the outer needle charging hole 16 in the biopsy device 10 fixed on the fixing part 100. |
