Embodiment Construction

[0055] Referring to the drawings, a surgical instrument 50 is shown, wherein like reference numerals indicate corresponding parts throughout the several views.

[0056] In the first embodiment, as figure 1 As shown in , the surgical instrument 50 is forceps, primarily for performing endoscopic or arthroscopic procedures, and specifically for grasping objects during such procedures. Components of surgical instrument 50 are typically formed from metal, such as stainless steel. However, the various components of the surgical instrument may be formed from other materials known to those skilled in the art.

[0057] now refer to figure 2, surgical instrument 50 includes a shaft 52 having a proximal end 54 and a distal end 56 . Preferably, shaft 52 is rod-shaped, having a generally circular cross-section. However, the cross-section of shaft 52 may define other shapes. For example, the cross-section of shaft 52 may be square or triangular (neither shown).

[0058] The shaft 52...

Abstract

A surgical instrument includes a detachable tool assembly. The assembly includes a connection rod and a tool, such as a pair of jaws or an electrode. The instrument also includes a shaft operatively connected to a handle movable between operating positions and an ejected position. A tubular housing encloses the shaft and a collet. The collet is attached to the rod and movable between the positions. The fingers of the collet are flared apart in the ejected position but collapse to capture the connection rod in the operating positions. A tongue-and-groove arrangement provides a secondary coupling between the assembly and the housing when the handle is in the operating positions.

Description

[0001] Cross-references to related applications [0002] This patent application claims priority to and all benefit of US Provisional Patent Application No. 60 / 818,159, filed June 30, 2006, the entire specification of which application is expressly incorporated herein by reference. technical field [0003] The present invention relates to a surgical instrument having a removable tool assembly. Background technique [0004] Surgical instruments, such as forceps, are well known in the art for use in surgery and other medical procedures. Typically, tweezers, such as Kelly tweezers, have a two-piece construction like scissors, but are used for gripping rather than cutting. These commonly used tweezers include a pair of handles attached to a pair of jaws. [0005] In advanced endoscopic and arthroscopic procedures, the surgeon may require several different types and sizes of jaws depending on a variety of factors. To save on disposal and sterilization costs, medical device su...
