Abstract

A surgical system is disclosed. The surgical system comprises a housing, a surgical device and an adapter. The housing includes a distal end. The surgical device comprises, a cutting element extending from the housing at the distal end. The cutting element is selectively rotated and translated relative to a tissue biopsy area. The adapter is configured to selectively and detachably receive the surgical device. The adapter secures the surgical device thereto by at least one latching mechanism such that the surgical device is prevented from moving independently from the adapter.

Claims

1. A surgical device, comprising

an outer cannula;

an inner cannula slidably disposed in the outer cannula; and

a spring operatively connected to the outer cannula and the inner cannula,

wherein the spring is configured to fire the outer cannula in a distal direction relative to the surgical device,

wherein the spring is configured to move the inner cannula in a proximal direction relative to the surgical device,

wherein the outer cannula is configured such to retract in the proximal direction relative to the surgical device in response to fluid pressure, and

wherein the inner cannula is configured to move in the distal direction relative to the surgical device in response to fluid pressure.

2. The surgical device of claim 1, further comprising a front enclosure defining a biopsy cavity positioned proximally of a rear enclosure defining a spool cavity, wherein the spring is configured to fire the outer cannula in the distal direction relative to the surgical device, when fluid pressure is vented from the spool cavity, and the spring is configured to move the inner cannula in the proximal direction relative to the surgical device, when fluid pressure is vented from the biopsy cavity.

3. The surgical device of claim 1, further comprising a motor operatively connected to the inner cannula and disposed between the biopsy cavity and the spring, wherein the motor is configured to rotate the inner cannula.

4. The surgical device of claim 3, wherein the motor is configured to fire in the distal direction when fluid pressure is applied to the biopsy cavity, thereby compressing the spring.

5. The surgical device of claim 3, wherein the motor is configured to fire in the distal direction relative to the surgical device, when fluid pressure is applied to the biopsy cavity, thereby moving the inner cannula in the distal direction relative to the surgical device, and the spring is configured to retract the motor in the proximal direction relative to the surgical device, when fluid pressure is vented from the biopsy cavity, thereby moving the inner cannula in the proximal direction relative to the surgical device.
