Abstract

A surgical device is disclosed that comprises a cutting element, a biopsy line, a motor line, and a vacuum line. The cutting element includes an outer cannula and an inner cannula. The biopsy line is operatively connected to a control console for moving the inner cannula within the outer cannula to cut tissue cores. The motor line is operatively connected to the control console for operating the surgical device. The vacuum line is operatively connected to the inner cannula. A selectively openable tissue filter is operatively connected to the inner cannula, and is also connected to the vacuum line.

Claims

1. A surgical system, comprising:

a control console;

a surgical device including a cutting element comprising an outer cannula and an inner cannula;

a biopsy line configured to operatively connect the surgical device to the control console for supplying pressurized air from the control console to move the inner cannula longitudinally relative to the outer cannula; and

a motor line configured to operatively connect the surgical device to the control console for supplying pressurized air from the control console to rotate the inner cannula relative to the outer cannula,

wherein the biopsy line and motor line each include a first section and a second section, the first sections each having a distal end attached to the surgical device, and the second sections each having a proximal end operatively connected to the control console,

wherein respective distal ends of the second sections are selectively connectable to respective proximal ends of the first sections, and

wherein the respective second sections are reusable after operation of the surgical device,

the surgical system further comprising a firing line configured to operatively connect the surgical device to the control console for supplying pressurized air from the control console to control longitudinal motion of the outer cannula relative to a body of the surgical device, wherein the firing line includes first and second sections,

wherein the first section of the firing line has a distal end attached to the surgical device, and the second section of the firing line has a proximal end that is operatively connected to the control console,

wherein a distal end of the second section of the firing line is selectively connectable to a proximal end of the first section of the firing line, and

wherein the second section of the firing line is reusable after operation of the surgical device.

2. The surgical system of claim 1, wherein the respective proximal ends of the first sections of the biopsy line and motor line each comprises a first connector member that is configured to selectively mate with a corresponding second connector member positioned on the respective distal ends of the second sections of the biopsy line and motor line so as to fluidly connect the first sections of the biopsy line and the motor line to the control console.

3. The surgical system of claim 2, wherein the first connector members are configured as male connector members, and the second connector members are configured as female connector members.

4. The surgical system of claim 3, wherein the first connector members each comprises a seal member.

5. The surgical system of claim 3, further comprising a selectively releasable latching mechanism that is configured to selectively secure the first connector members to the second connector members.

6. The surgical system of claim 2,

wherein the first sections of the biopsy and motor lines are secured together by a first manifold such that the first connector members extend outwardly from the first manifold, and the second sections of the biopsy and motor lines are secured together by a second manifold such that the second connector members extend outwardly from the second manifold, and

wherein the first and second manifolds are configured to mate together when the first connector members are secured to the second connector members.

7. The surgical system of claim 1, further comprising a remote valve operatively connected to a pressure line connected to the control console, wherein the respective proximal ends of the second sections of the biopsy and firing lines are configured to be operatively connected to the remote valve.

8. The surgical system of claim 7, further comprising a motor line sensor disposed within the motor line, a firing line sensor disposed within the firing line, and a pressure line sensor disposed within the pressure line, wherein the sensors are operatively connected to an indicator to communicate errors during an operational mode of the control console.

9. The surgical system of claim 8, wherein the control console is selectively operable within at least a lavage operational mode and a biopsy operational mode, wherein the firing line sensor is configured to detect the pressure within the firing line when the control console is placed in the lavage operational mode, and the firing line sensor is further configured to send an error signal to actuate the indicator if the pressure within the firing line is below 30 psi.

10. The surgical system of claim 9, wherein the indicator is positioned on one of the remote valve, surgical device, and control console.

11. The surgical system of claim 9, wherein the firing line sensor is positioned within the second section of the firing line.

12. The surgical system of claim 8, wherein the firing line sensor is configured to detect pressure within the firing line, the motor line sensor is configured to detect pressure within the motor line, and wherein the firing line sensor and motor line sensors are configured to cooperate to send an error signal to actuate the indicator if both the firing line sensor and the motor line sensors detect pressure of at least 30 psi.

13. The surgical system of claim 8, wherein the motor line sensor is configured to detect pressure within the motor line, and the pressure line sensor is configured to detect pressure within the pressure line, and wherein the motor line sensor and pressure line sensors are configured to cooperate to send an error signal to actuate the indicator if the motor line sensor detects a pressure of at least 30 psi but the pressure line sensor does not detect a pressure of at least 30 psi.

14. The surgical system of claim 1, further comprising a remote toggle switch assembly, wherein the remote toggle switch assembly comprises:

a first three-way valve positioned between the control console and the first section of the motor line,

a second three-way valve positioned between the control console and the first section of the biopsy line, and

a connector tube positioned between the first and second three-way valves,

wherein the first and second three-way valves are configurable to establish or modify respective fluid pathways between the control console and the surgical device.

15. A tissue filter assembly for collecting tissue excised by a tissue cutting device, the filter assembly comprising:

a cap defining a tissue inlet port configured to be attached to a flexible tubing tissue aspiration line that is in fluid communication with the tissue cutting device;

a filter can having an open end configured for removable attachment to the cap, the filter can defining a chamber therein and further defining a vacuum access port configured to attach to a flexible tubing vacuum line, such that, when the tissue aspiration line is attached to the inlet port, and when the cap is attached to the can, and when the vacuum line is attached to the vacuum access port, the respective aspiration line, can chamber and vacuum line are in fluid communication with each other;

the cap and the filter can having a bayonet mount for removable attachment to each other;

a porous filter trap sized and configured to be removably seated in the filter can chamber and configured for collecting tissue; and

a gasket disposed around an open end of the filter trap, the gasket configured to be compressed between the cap and an outer periphery of the filter can to create a vacuum-tight seal when the filter trap is seated within the filter can chamber and the cap is attached to the filter can,
