Abstract: A handle for a surgical instrument is described comprising: a body member for attachment to an outer shaft of a surgical instrument; a rotatable member at least partially disposed within the body member for rotation about a longitudinal axis and comprising a first helical thread formed on an outer surface and a second helical thread; a translatable member for attachment to an inner shaft of a surgical instrument, adapted for movement along the longitudinal axis relative to the rotatable member and having a helical thread engaged with the second helical thread of the rotatable member; a shuttle member disposed around the rotatable member comprising a ratchet mechanism having a pawl for engaging the first helical thread; and an actuation member having a first end pivotally attached to the body member and a second end coupled to the shuttle member. This construction provides greater mechanical advantage and control over movement of the translatable member, and therefore the relative movement of an inner shaft of a surgical instrument attached to the handle.

Abstract: A handle for a surgical instrument which includes two protrusions set at different distances from the end of the handle. Depending on the hand size of a user, the user can select which protrusion to use. The handle reduces instrument inventory by allowing use of the same instrument handle by users with different hand sizes. A surgical instrument using the handle is also described. In one embodiment the handle comprises a housing defining a longitudinal axis. A first end of the housing is at one end of the longitudinal axis. The housing comprises a first protrusion positioned a first distance from the first end of the housing for use by a user having a first size of hand and a second protrusion positioned a second distance from the first end of the housing for use by a user having a second size of hand. Both the first protrusion and the second protrusion are configured to receive a digit of a user and to allow the digit to apply a force to the housing in the direction of the longitudinal axis towards the first end. The first distance is greater than the second distance. Depending on the user's size of hand they can select which of the first or second protrusions to use.

Abstract: Cannula sealing apparatus includes a housing (28) having a central axially facing aperture (32). A surgical instrument of 10.5 mm may seal with that aperture (32). Alternatively, a sealing member (34) having an aperture that will seal with a 12mm surgical instrument can be swung up to be aligned with the aperture (32). If a 10.5 mm instrument is required then a seal member (36) can be swung up to have its seal aperture located over the central aperture (32). Each seal member (34) and (36) is pivotal about a common axis. Each seal member (34) and (36) has a surface that faces a housing (28) such that both parts can seal at their facing surfaces when either of the seal members are swung up into the position where the opening is over the central opening (32).

Abstract: A sheet (12) is mounted on the side arms (11). When the retractor is inserted through a restricted opening, a tube surrounds the rod (10) and the arms (11) and encloses the sheet in a folded configuration. With the retractor located inside a body cavity the surrounding tube is withdrawn to expose the sheet (12). The arms (11) are then moved apart until the sheet (12) is taut. The taut sheet (12) is then able to be urged against the part of the body which is required to be pushed to one side.

Abstract: A surgical positioning assembly for use with a surgical instrument which has an elongated shaft defining a longitudinal axis, for example a minimally invasive surgical instrument. The positioning assembly comprises: a base member comprising a skin contact surface, wherein the base member defines an opening for the elongated shaft; a rotating assembly configured to rotate relative to the base member about a rotation point located below the skin contact surface wherein the rotating assembly defines an opening for the elongated shaft; and a locking mechanism for locking the position of the positioning assembly on the elongated shaft and for locking the orientation of the rotating assembly relative to the base member. In use, the elongated shaft of the surgical instrument will exert stress on the abdominal wall as the shaft is moved relative to abdominal wall. It has been found that the stress on the abdominal wall is reduced if the rotation point is below the skin of the patent. As a further benefit the reduced stress allows easier movement of the surgical instrument.

Abstract: A handle (2) for a surgical instrument is described. The handle comprises a housing (4) for attachment to an outer shaft of a surgical instrument and defining a longitudinal axis. An adjustment member (6) comprises a first bevel gear (12) mounted for rotation about an adjustment axis perpendicular to the longitudinal axis. A second bevel gear (26) is engaged with the first bevel gear and mounted to rotate about an axis parallel to the longitudinal axis. A translatable member (36) is provided for attachment to an inner member of a surgical instrument and is configured to move relative to the housing along the longitudinal axis in response to rotation of the second bevel gear. In one embodiment the handle is for a minimally invasive surgical instrument having a segment string at its distal end. The configuration of the handle allows one handed use. The adjustment member can be operated by the same hand which is holding the handle. A surgical retractor instrument (44) including the handle is also described

Abstract: A trocar tip has a longitudinal axis and comprises: an end portion coincident with the longitudinal axis; and a tapered portion extending to the end portion and narrowing in the direction towards the end portion. The tapered portion comprises a conical surface about the longitudinal axis and two concave surfaces which are defined by cut outs from the conical surface and which extend along the entire length of the of the tapered portion. The concave surfaces are preferably on opposite sides of the tapered portion and symmetrical about a plane passing through the longitudinal axis. The trocar tip with this construction is simple to manufacture and effective at enlarging an incision.
