## Abstract

A cleaner device is adapted to clean a blood vessel sealer device. The cleaner device includes a series of brushes that can move relative to blood vessel sealer device to scrub and clean the blood vessel sealer device when coupled to the cleaner device. The brushes can be made of any material that is adapted to clean the blood vessel sealer device. The cleaner device can also be motorized to facilitate cleaning of the blood vessel sealer device.

## Claims

### Claim 1

A method of cleaning a blood vessel sealing device, comprising:
inserting at least a portion of a blood vessel sealer device into a cleaner device, the cleaner device comprising:
a housing defining a cavity;
at least one brush inside the cavity, wherein the at least one brush is positioned inside the cavity such that at least a portion of a blood vessel sealer device can be inserted inside the cavity in contact with the at least one brush, wherein the at least one brush moves relative to the at least a portion of the blood vessel sealer device so as to scrub the at least a portion of the blood vessel sealer device when the at least a portion of the blood vessel sealer device is inside the cavity
causing the at least one brush to scrub the vessel sealer device by manually moving the at least one brush or by activating a motor that causes the at least one brush to move relative to the blood vessel sealer device.

### Claim 2 (depends on 1)

The method of claim 1, wherein the at least one brush includes an outer brush and an inner brush.

### Claim 3 (depends on 2)

The method of claim 2, wherein the outer brush is positioned to clean an outer portion of the at least a portion of the blood vessel sealer device.

### Claim 4 (depends on 2)

The method of claim 2, wherein the inner brush is positioned to clean an inner portion of the at least a portion of the blood vessel sealer device.

### Claim 5 (depends on 1)

The method of claim 1, wherein the at least a portion of a blood vessel sealer device is a pair of jaws.

### Claim 6 (depends on 1)

The method of claim 1, further comprising a motor that moves the at least one brush.

### Claim 7 (depends on 1)

The method of claim 1, wherein the at least one brush rotates relative to the housing.

### Claim 8 (depends on 1)

The method of claim 1, further comprising a reservoir.

### Claim 9 (depends on 8)

The method of claim 8, wherein the reservoir is inside the hub.
