Claim 1:
2. The biopsy instrument according to claim 1, wherein the trigger (500) comprises:
an inner needle-coupling bar (530) protruding from the grip button (510) toward the base (100) so as to be coupled to the inner needle (200); and
a locking catching bar (540) formed between the carrier connection bar (520) and the inner needle-coupling bar (530) such that a movement route thereof is closed by the locking member (800),
wherein the carrier connection bar (520) comprises a traction protrusion (521) formed at a front end thereof so as to protrude upwards,
wherein the locking member (800) comprises:
a lower rotary member (810) formed to have an arc-shaped outer circumference, the lower rotary member having therein a bar movement hole (815) formed corresponding to a sectional shape of a movement position limiting bar (525), the lower rotary member being disposed on a bottom surface of the base (100);
an upper pressing member (820) formed to have a semicircular-shaped section, the upper pressing member comprising one end, fixed to one end of the lower rotary member (810), and a remaining end, spaced apart from a remaining end of the lower rotary member (810) by a predetermined distance; and
the unlocking button (830) protruding from an upper surface of the upper pressing member (820) so as to be exposed to an outside of the casing (700),
wherein, when the unlocking button (830) is not pressed, the bar movement hole (815) is misaligned from the locking catching bar (540) such that the locking catching bar (540) is prevented from being moved forwards, and
wherein, when the unlocking button (830) is pressed, the upper pressing member (820) is moved downwards to press the lower rotary member (810) such that the lower rotary member (810) is rotated on a surface of the base (100), and the bar movement hole (815) is coaxially aligned with the locking catching bar (540) such that the locking catching bar (540) is allowed to be moved forwards.
