Embodiment Construction

[0091] refer to figure 1 , providing a background for embodiments of the invention, figure 1 A conventional manual laparoscopic instrument 10 is depicted. The instrument 10 includes three main components, namely a handle 12 , an outer sheath 14 and an insert 16 . The insert 16 includes a rod 18 provided with a roll 20 at a proximal end and a tool 22 at an opposite distal end. Ball 20 is received in a socket (not shown) in handle 12 to provide a mechanical coupling between handle 12 and insert 16 . The handle 12 is formed with two arms or rods 15 pivotally coupled together. A finger ring 17 is provided at one end of each arm 15 to hold the handle 12 . A releasable locking mechanism 19 is attached between the arms 15 and is operable to retain the arms 15 at a fixed angle relative to each other.

[0092] Before insert 16 is coupled to handle 12 , it is inserted into outer sheath 14 such that tool 22 is proximate distal end 24 of outer sheath 14 . When in this configuration,...

Abstract

An insert (30) comprises a rod (32) having a proximal end (34) and a distal end (36). The insert (30) also comprises a tool (38) which is demountably coupled to the distal end (36). Proximal end (34) is formed with a ball (40) which is configured to seat and engage in a socket of a handle (12) of a laparoscopic instrument (10). The rod (32) fits within a sheath (14) of the laparoscopic instrument (10). The distal end (36) of the rod (32) is provided with an attachment head 42 to facilitate the attachment of the tool (38). A linkage mechanism (44) in the attachment head (42) converts the linear motion of the insert (30) (and in particular rod 32) relative to the outer sheath (14) to a pivotal motion.

Description

technical field [0001] The present invention relates to inserts and insertion systems for laparoscopic instruments. Background technique [0002] Laparoscopic instruments include handles, outer sheaths and inserts. The outer sheath can be fixed to the handle or alternatively be detachable from the handle. An insert extends through the sheath and is operatively coupled to the handle. The handle has two finger loops similar to a pair of regular scissors. The insert moves linearly relative to the outer sheath when the handle is manipulated by holding the finger rings together or separating them. The insert is provided with an integrated tool at its distal end. Linear movement of the insert relative to the sheath operates the tool. This can be evidenced, for example, by opening and closing the jaws or blades of the tool. The function and nature of the tool determine the type of insert. Types of inserts include scissors, dissectors, forceps, and needle holders. Furthermor...
