## Abstract

A multi-utility surgical instrument may include a nosecone, a handle, a housing sleeve, an actuation facilitating sleeve, a piston tube, a hypodermic tube, and an end plug. The hypodermic tube may be disposed within the piston tube; the piston tube may be disposed within the actuation facilitating sleeve; the actuation facilitating sleeve may be disposed within the housing sleeve; the end plug may be disposed within a portion of the housing sleeve; the housing sleeve and the end plug may be disposed within the handle; the nose cone may be fixed to a distal end of the handle; and the hypodermic tube may be fixed to the nosecone.

## Claims

### Claim 1

An instrument comprising:
a handle having a handle distal end and a handle proximal end;
a housing sleeve disposed within the handle;
an end plug disposed within the handle, the end plug having an end plug inner bore and a surgical blank housing;
a nosecone attached to the handle distal end, the nosecone having a nosecone inner bore;
an inner hypodermic tube fixed to the nosecone;
an outer hypodermic tube having an outer hypodermic tube distal end and an outer hypodermic tube proximal end wherein the outer hypodermic tube proximal end is fixed to the nosecone; and
an interface taper of the end plug configured to interface with a syringe wherein the syringe is configured to flush a fluid into the end plug inner bore and expel the fluid out from the outer hypodermic tube distal end.

### Claim 2 (depends on 1)

The instrument of claim 1 further comprising:
a surgical blank disposed within the outer hypodermic tube, the nosecone inner bore, the inner hypodermic tube, and the surgical blank housing.

### Claim 3 (depends on 2)

The instrument of claim 2 wherein the syringe is configured to remove biological matter from a distal end of the surgical blank.

### Claim 4 (depends on 3)

The instrument of claim 3 wherein the distal end of the surgical blank comprises a forceps.

### Claim 5 (depends on 3)

The instrument of claim 3 wherein the distal end of the surgical blank comprises a scissors.

### Claim 6 (depends on 1)

The instrument of claim 1 further comprising:
a link;
a first link pin connecting the link to the nosecone; and
a second link pin connecting the link to the handle.

### Claim 7 (depends on 1)

The instrument of claim 1 further comprising:
an actuation facilitating sleeve having an actuation facilitating sleeve distal end and an actuation facilitating sleeve proximal end.

### Claim 8 (depends on 7)

The instrument of claim 7 wherein at least a portion of the actuation facilitating sleeve comprises a non-crystalline material.

### Claim 9 (depends on 8)

The instrument of claim 8 wherein the non-crystalline material is glass.

### Claim 10 (depends on 7)

The instrument of claim 7 wherein at least a portion of the actuation facilitating sleeve comprises a carbon allotrope.

### Claim 11 (depends on 10)

The instrument of claim 10 wherein the carbon allotrope is graphite.

### Claim 12 (depends on 1)

The instrument of claim 1 further comprising:
a piston tube having a piston tube distal end and a piston tube proximal end.

### Claim 13 (depends on 12)

The instrument of claim 12 wherein at least a portion of the piston tube comprises a non-crystalline material.

### Claim 14 (depends on 13)

The instrument of claim 13 wherein the non-crystalline material is glass.

### Claim 15 (depends on 12)

The instrument of claim 12 wherein at least a portion of the piston tube comprises a carbon allotrope.

### Claim 16 (depends on 15)

The instrument of claim 15 wherein the carbon allotrope is graphite.

### Claim 17 (depends on 1)

The instrument of claim 1 further comprising:
an actuation facilitating sleeve disposed in the housing sleeve; and
a piston tube disposed in the actuation facilitating sleeve.

### Claim 18 (depends on 17)

The instrument of claim 17 wherein at least a portion of the actuation facilitating sleeve comprises a carbon allotrope and wherein at least a portion of the piston tube comprises a non-crystalline material.

### Claim 19 (depends on 17)

The instrument of claim 17 wherein at least a portion of the actuation facilitating sleeve comprises a non-crystalline material and wherein at least a portion of the piston tube comprises a carbon allotrope.
