## Abstract

A protective tissue cover having a sleeve configuration to slide onto the working portion of a surgical instrument, such as a retractor. At least the contact side of the protective tissue cover is constructed from smooth antimicrobial material that minimizes contact irritation with tissue. Alternative embodiments include various multiple-ply constructions that incorporate an antimicrobial layer, an absorbent layer, and other medical layers to assist in surgical procedures.

## Claims

### Claim 1

A system for providing tissue protection, comprising:
a medical tool having a working portion;
a protective tissue cover that includes a sleeve configuration having (1) an outer contact surface with a closed end and an open end, the outer contact surface of the protective tissue is constructed from a smooth antimicrobial material for minimizing potential contact irritation with tissue during a surgical procedure, (2) an inner contact surface for contacting the medical tool, and (3) a central layer positioned between the outer contact surface and the inner contact surface, the central layer including medicaments that are transported directly to tissue in contact with the protective tissue cover during a surgery.

### Claim 2 (depends on 1)

The system of claim 1, wherein the smooth antimicrobial material is an elastomeric polymer impregnated with at least one antimicrobial selected from the group consisting of iodine, chlorhexidine, collagen, vitamin D, quaternary amines, halamine, and silver.

### Claim 3 (depends on 1)

The system of claim 1, further comprising a testing material attached to the protective tissue cover to determine the state of the contacted tissue.

### Claim 4

A system for providing tissue protection, comprising:
a medical tool having a working portion;
a protective tissue cover, the tissue cover having:
a first layer having a smooth surface and including an antimicrobial material;
a second layer connected to the first layer; and
a third layer disposed between the first layer and the second layer, the third layer includes medicaments, which are transported directly to tissue in contact with the protective tissue cover during a surgery.

### Claim 5 (depends on 4)

The protective tissue cover of claim 4, wherein the first layer includes a polymer impregnated with at least one antimicrobial selected from the group consisting of iodine, chlorhexidine, collagen, vitamin D, quaternary amines, halamine, and silver.

### Claim 6 (depends on 4)

The protective tissue cover of claim 4, wherein the second layer includes at least one material selected from the group consisting of polymers and residue-resistant cotton.

### Claim 7 (depends on 4)

The protective tissue cover of claim 4, further comprising a detection strip embedded in the first layer.

### Claim 8 (depends on 7)

The protective tissue cover of claim 7, wherein the detection strip comprises at least one material selected from the group consisting of barium and salts, non-ferromagnetic metals, plastic, and detectable coatings.

### Claim 9 (depends on 4)

The protective tissue cover of claim 4, wherein the third layer includes at least one material selected from the group consisting of a machine-scan detectable material, a controllable thermogenic material, and medicinal material.

### Claim 10 (depends on 4)

The protective tissue cover of claim 4, wherein the first, second and third layers include perforations for tearing the protective tissue cover to a desired length.

### Claim 11 (depends on 4)

The protective tissue cover according to claim 4, wherein the first layer includes a plurality of microtubes formed there through, the microtubes permitting passage of fluids between the first, second and third layers.

### Claim 12 (depends on 4)

The protective tissue cover of claim 4, further comprising a suction shroud covering at least a portion of the first layer, the suction shroud having an adapter for selective connection to a suction device.

### Claim 13

A system for providing tissue protection, comprising:
a medical tool having a working portion;
a protective tissue cover that includes a sleeve configuration having an outer contact surface with a closed end and an open end, the outer contact surface of the protective tissue is constructed from a smooth antimicrobial material for minimizing potential contact irritation with tissue during a surgical procedure, and an adjacent layer positioned next to the outer contact surface, the adjacent layer including medicaments that are transported directly to tissue in contact with the protective tissue cover during a surgery.

### Claim 14 (depends on 13)

The system of claim 13, wherein the smooth antimicrobial material is an elastomeric polymer impregnated with at least one antimicrobial selected from the group consisting of iodine, chlorhexidine, collagen, vitamin D, quaternary amines, halamine, and silver.

### Claim 15 (depends on 13)

The system of claim 13, further comprising a testing material attached to the protective tissue cover to determine the state of the contacted tissue.

### Claim 16 (depends on 13)

The system of claim 13, further comprising a detection strip embedded in the outer contact surface.

### Claim 17 (depends on 16)

The system of claim 16, wherein the detection strip comprises at least one material selected from the group consisting of barium and salts, non-ferromagnetic metals, plastic, and detectable coatings.

### Claim 18 (depends on 13)

The system of claim 13, wherein the adjacent layer includes at least one material selected from the group consisting of a machine-scan detectable material, a controllable thermogenic material, and medicinal material.

### Claim 19 (depends on 13)

The system of claim 13, wherein the outer contact surface and the adjacent layer include perforations for tearing the protective tissue cover to a desired length.

### Claim 20 (depends on 13)

The system of claim 13, further comprising a suction shroud covering at least a portion of the outer contact surface, the suction shroud having an adapter for selective connection to a suction device.
