Abstract
An improved rongeur for cutting bone or cartilage comprising two shaft members capable of reciprocating motion relative to each other wherein one shaft member terminates in a foot plate and the other shaft member comprises a combined cutting element and storage member is disclosed. The combined cutting element and storage member has a cutting edge at its distal end and a storage chamber proximate the cutting edge for collecting and storing cut pieces of bone or cartilage in an amount greater than the maximum bone or cartilage capable of being cut in a single full cut. The combined cutting element and storage member is truly disposable, rather than merely replaceable and requires the use of no tools or special assembly. The rongeur may be manually activated or activated by a solenoid and powered by a battery.
Claims24
A method for cutting bone or cartilage in a surgical procedure, the method comprising:
- providing a rongeur having a shaft with a foot plate extending therefrom and a hollow member in slidable relationship to the shaft, the hollow member having a mid-longitudinal axis, a cutting edge, and an interior that is adapted to receive cuts of bone or cartilage therein, the interior having a length along a longitudinal axis of the rongeur;
- positioning the rongeur at a site in the human body where the bone or cartilage is to be cut;
- cutting and storing bone or cartilage with the rongeur by positioning a majority of the cutting edge of the hollow member in contact with the foot plate to produce multiple cut pieces of bone or cartilage which are stored along at least a portion of the length of the interior of the hollow member, the cutting edge of the hollow member and the foot plate being in a fixed rotational relationship about the mid-longitudinal axis of the hollow member when in contact with each other;
- preventing the cut pieces of bone or cartilage from contacting the shaft from within the hollow member, and
- preventing the ejection of all previously cut pieces of bone or cartilage from the interior of the hollow member along the entire length of the interior of the hollow member while additional cuts of the bone or cartilage are being made with the rongeur.
A method for cutting bone or cartilage in a surgical procedure, the method comprising:
- providing a rongeur having a body, a shaft with a foot plate extending therefrom and a storage member in slidable relationship to the shaft, the storage member having a cutting edge and a storage area adapted to store multiple cuts of bone or cartilage;
- positioning the rongeur at least in part within the human body where the bone or cartilage is to be cut;
- cutting and storing bone or cartilage with the rongeur to produce multiple cut pieces of bone or cartilage, the cut pieces of bone or cartilage being stored within the storage area of the storage member;
- separating the storage member from the shaft and the body of the rongeur without separating the shaft from the body of the rongeur, the multiple cut pieces of bone or cartilage remaining within the storage area of the storage member during the separating of the storage member from the shaft;
- and
- then removing the multiple cut pieces of bone or cartilage from the storage area of the storage member.
