## Abstract

A scraper is provided having at least a portion of a fastener thereon. A blade is removably attachable to the distal end of the scraper through this fastener. The blade includes a cutting edge extending beyond portions of the distal end so that the cutting edge of the blade can be used when the blade is attached to the scraper. One form of fastener includes a pin and a hole, both on the distal end of the scraper. The blade is provided with a yoke that engages the pin, and a stud which passes through the hole, so that the blade is secured to the distal end of the scraper. A container is also disclosed with a lower tray and cover tray configured to hold multiple scrapers therein.

## Claims

### Claim 1

A surgical scraper, the scraper comprising:
an elongate rigid body extending between a proximal end and a distal end, the proximal end including a handle adapted to be gripped by a hand of a user;
a head located at the distal end, the head including a pin and a hole, and
a blade of thin form having a proximal side, a distal side opposite the proximal side and having a cutting edge thereon, the blade having a slot and a stud, wherein the slot is configured to receive the pin therein and the stud is configured to be inserted into the hole;
wherein the slot and the pin cooperate and the stud and the hole cooperate to hold the blade on the head of the scraper; and
wherein the blade includes a yoke on the proximal side, the yoke including the slot therein, the pin having a cap thereon, the cap spaced from the face of the head of the scraper, the space being at least as great as a thickness of the blade at the yoke.

### Claim 2 (depends on 1)

The scraper of claim 1, wherein a step is provided in the blade between the yoke and the distal side of the blade, the step causing the yoke to be elevated above portions of the blade on a side of the step opposite the yoke.

### Claim 3 (depends on 2)

The scraper of claim 2, wherein the stud includes a groove on a portion of the stud below the thin form of the blade, a retainer having at least a portion thereof located within the groove and at least a portion thereof extending out of the groove, the hole in the head of the scraper having a beveled edge, the hole at least as long as a distance that the groove is spaced away from the thin form of the blade, such that the retainer can reside at least partially outside of the hole when the stud is located through the hole.

### Claim 4 (depends on 3)

The scraper of claim 3, wherein an upper end of the hole opposite the lower end includes a forward recess extending toward the distal end of the scraper.

### Claim 5

A method of for scraping bodily structures during surgery, the method comprising:
identifying a scraper having an elongate rigid body extending between a proximal end and a distal end, the proximal end including a handle adapted to be gripped by a hand of a user, the distal end including a head, the head including a pin and a hole, a first blade of thin form having a distal side with a cutting edge thereon, the first blade having a slot and a stud, wherein the slot is configured to receive the pin therein and the stud is configured to be inserted into the hole;
attaching the first blade to the distal end of the elongate rigid body of the scraper;
scraping a bodily structure with the cutting edge of the first blade;
striking the distal end of the scraper against a hard surface to remove the first blade;
removing the first blade from the head of the scraper; and
attaching a second blade to the head of the scraper.

### Claim 6 (depends on 5)

The method of claim 5, wherein the identifying step includes the pin fitting within the slot to at least partially hold the first blade to the head, the stud extending non-parallel with a plane tangent to the thin form of the first blade, the stud sized to fit within the hole to at least partially hold the first blade to the head of the scraper, the stud having a base tip extending out past a rear surface of the scraper.

### Claim 7 (depends on 6)

The method of claim 6, wherein the attaching step includes:
passing the base tip into a forward recess, then into the hole until the retainer extends at least partially out of the lower end of the hole.
