Description

FIELD OF THE INVENTION

The present disclosure relates to a medical device, and, more particularly, to a surgical instrument.

BACKGROUND OF THE INVENTION

A variety of surgical procedures are performed through a very small surgical incision in a particular tissue. Reducing the size of a surgical incision during a surgical procedure generally reduces the amount of trauma to the surgical site and generally facilitates faster wound healing. In order to perform surgical procedures through a very small surgical incision, a surgeon may require specialized surgical instruments configured to fit through the very small surgical incision and provide the surgeon with a surgical utility. Sometimes a surgeon may require a surgical utility that may not be easily controlled close to a particular surgical site, e.g., closing forceps jaws inside of an eye. It is generally desirable for a surgeon to be able to control such a surgical utility with a minimal amount of effort. For example, if a surgical utility is controlled by a lever or a switch on an instrument handle, a surgeon may need to adjust an orientation of a surgical instrument in order to actuate the lever or the switch. Additionally, if a surgical utility control mechanism requires a surgeon to apply a significant amount of force to a portion of a surgical instrument, then it may be difficult for the surgeon to manipulate the surgical utility control mechanism without unintentionally moving a portion of the surgical instrument.

Ophthalmic surgical instruments are generally categorized as either reusable or single-use. A single-use instrument is typically sterilized prior to sale and is shipped to a surgery center sterile and ready for use in a surgical procedure. A reusable instrument is typically shipped to a surgery center non-sterile and is sterilized by the surgery center between uses in surgery. Reusable instruments are generally lower in overall cost for a surgery center compared to single-use instruments. Single-use instruments offer a surgery center greater convenience compared to reusable instruments. Accordingly, there is a need for an instrument that offers a surgery center the convenience of a single-use instrument at the overall lower cost of a reusable instrument.

BRIEF SUMMARY OF THE INVENTION

The present disclosure provides an instrument handle and replaceable tip. In one or more embodiments, an instrument handle and replaceable tip may comprise a reusable instrument handle and a single-use instrument tip. Illustratively, the instrument tip may comprise an outer base, a nosecone, a pressure mechanism, a hypodermic tube, a blank, and a fixation mechanism. In one or more embodiments, the instrument handle may comprise an actuation structure, a fixation mechanism receptacle, and an instrument tip housing. Illustratively, the fixation mechanism and the fixation mechanism receptacle may be configured to temporarily fix the instrument tip in the instrument tip housing. In one or more embodiments, a compression of the actuation structure may be configured to actuate the hypodermic tube relative to the blank. Illustratively, the instrument tip may be removed from the instrument tip housing after use by removing the fixation mechanism from the fixation mechanism receptacle.
