Abstract

A medical device comprises an articulated string of hollow plastic beads which lock into each other. The medical device will attach to an operating-room table-rail and hold a nozzle or suction scoop in a given position near the surgical site to evacuate airborne hazardous smoke fumes. The medical device will eliminate the need for an operating room nurse who in the past may be been solely responsible for manually holding the prior art nozzles or suction scoops in the vicinity of the surgical site. A surgeon will be able control by one hand the aiming and positioning of the nozzle or suction scoop by grabbing and configuring the medical device via a quick thrusting action. The medical device will remain in place until moved into another position.

Claims

1. A medical device for aiding evacuation of airborne and hazardous biological smoke fumes produced by surgically burnt tissue in an operating room, the device comprising:

a nozzle;

a hose fitting connected in fluid communication with the nozzle;

a base fixture for mounting to a stable support structure in the operating room;

an elongated chain of multiple inter-connected segments, which chain extends between and interconnects the nozzle and base fixture; and

,

an elongated flexible liner encasing the nozzle and chain substantially from a point of origin about the nozzle, to a point of termination toward the base fixture;

wherein, each one segment is configured to be capable of connecting to another adjacent segment such that frictional gripping between the one and other segment holds the one and other segments in a relatively rigid given alignment, the segments being further configured such that the frictional gripping therebetween can be sufficiently overcome by an applied external force such as the gripping and pulling and thrusting by a user so that the alignment of the chain as a whole is diversely changeable from one given alignment of relative flexion to another; and

,

wherein the hose fitting and sheath are sized and arranged to permit a evacuator hose connected to suction and filtration equipment to connect to the hose fitting and allow the evacuator hose to extend away to the suction and filtration equipment in a direction relatively away from the terminal end of the sheath;

whereby aiming the nozzle at a source of the hazardous biological smoke fumes draws the fumes in through the nozzle and safely away to the suction and filtration equipment.

2. The of medical device of claim 1, wherein the elongated flexible liner has a substantially closed end at the point of origin thereof, whereby a user can form a seal between the closed end and nozzle by puncturing the nozzle through the closed end.

3. The of medical device of claim 1, wherein the hose fitting is formed as a branch off the nozzle such that the evacuator hose, when connected to the hose fitting, extends alongside the chain of segments and inside the liner, the evacuator hose thereby extending out the end of the liner at the point of termination thereof.

4. The of medical device of claim 1, wherein each segment is substantially hollow such that the chain of segments defines a lumen within, which lumen is sufficient in size to accept the insertion therein of the evacuator hose;

wherein one of the chain and the base fixture includes an exit for the evacuator hose remote from the nozzle; and

,

wherein the hose fitting is formed internally within the nozzle such that when the evacuator hose is connected to the hose fitting, the evacuator hose extends away inside the lumen of the chain and out through the exit, to extend off to the suction and filtration equipment.

5. The of medical device of claim 1, further comprising a coupler occupying a position between the base fixture and the chain of segments;

and,

wherein each segment is substantially hollow such that the chain of segments defines a lumen within, which lumen is sufficient in size to accept the insertion therein of the evacuator hose; and

,

the coupler includes a branch, portions of which are formed as the hose fitting, the coupler also being formed with an internal passage that allows fluid communication between the hose fitting and the lumen of the chain;

whereby the lumen of the chain defines that portion of the suction conduit that extends between the nozzle and hose fitting.

6. The of medical device of claim 1, wherein the chain can be alternatively lengthened and shortened by respectively adding and removing segments.

7. The of medical device of claim 1, wherein the each segment is configured to interconnect with another adjacent segment via reciprocal ball and socket structures.

8. A medical device for aiding evacuation of airborne and hazardous biological smoke fumes produced by surgically burnt tissue in an operating room, the device comprising:

a nozzle formed internally with a hose fitting;

a base fixture for mounting to a stable support structure in the operating room;

an elongated chain of multiple interconnected segments, which chain extends between and interconnects the nozzle and base fixture; and

,

wherein, each one segment is configured to be capable of connecting to another adjacent segment such that frictional gripping between the one and other segment holds the one and other segments in a relatively rigid given alignment, the segments being further configured such that the frictional gripping therebetween can be sufficiently overcome by an applied external force such as the gripping and pulling and thrusting by a user so that the alignment of the chain as a whole is diversely changeable from one given alignment of relative flexion to another; and

wherein each segment is substantially hollow such that the chain of segments defines a lumen within, which lumen is sufficient in size to accept the insertion therein of a given evacuator hose in the operating room;

one of the chain and the base fixture including an exit for the evacuator hose remote from the nozzle;

whereby, when the evacuator hose is connected to the hose fitting, the evacuator hose extends away from the nozzle inside the lumen of the chain, and out through the exit, to extend off to suction and filtration equipment such that aiming the nozzle at a source of the hazardous biological smoke fumes draws the fumes in through the nozzle and safely away to the suction and filtration equipment.

9. A medical device for aiding evacuation of airborne and hazardous biological smoke fumes produced by surgically burnt tissue in an operating room, the device comprising:

a nozzle;

a base fixture for mounting to a stable support structure in the operating room;

a coupler, having a branch that forms a hose fitting, connected to the base fixture; and

,

an elongated chain of multiple inter-connected segments, which chain extends between and interconnects the nozzle and coupler; and

,

wherein, each one segment is configured to be capable of connecting to another adjacent segment such that frictional gripping between the one and other segment holds the one and other segments in a relatively rigid given alignment, the segments being further configured such that the frictional gripping therebetween can be sufficiently overcome by an applied external force such as the gripping and pulling and thrusting by a user so that the alignment of the chain as a whole is diversely changeable from one given alignment of relative flexion to another; and

,

wherein each segment is substantially hollow such that the chain of segments defines a lumen within, which lumen is sufficient in size to act as a conduit of biological smoke fumes drawn in through the nozzle;

wherein the hose fitting is sized to accept the connection thereto of a given evacuator hose in the operating room;

whereby, when the evacuator hose is connected to the hose fitting, the evacuator hose extends away to suction and filtration equipment such that aiming the nozzle at a source of the hazardous biological smoke fumes draws the fumes in through the nozzle, through the length of the lumen to the coupler, and safely away to the suction and filtration equipment.
