Apparatus for inserting a surgical device at least partially through a wound opening
First Claim
1. An apparatus for inserting a surgical device at least partially through a wound opening, the apparatus comprising:
- a holder including;
a proximal portion having a proximal opening,a side portion having a slot,a distal portion having a distal opening, anda passage configured to receive at least a portion of the surgical device; and
a movable member coupled to the holder and movable relative to the holder, the movable member including;
a proximal portion,a shaft extending from the proximal portion of the movable member, the shaft entering the holder through the proximal opening and being received in the passage of the holder,a protrusion formed on an outer surface of the shaft, the protrusion extending into the slot of the holder, wherein the protrusion and the slot selectively limit relative motion between the movable member and the holder, anda distal portion configured to engage the surgical device.

Abstract
An apparatus (650) for inserting a distal ring (9) of a wound retractor device (2) through a wound opening comprises a bladeless tip (641) for creating the wound opening by forcing tissue apart, and a conveying device (5) for conveying the distal ring (9) through the wound opening. The conveying device (5) comprises a hook element (6) for engaging the distal ring (9) to convey the distal ring (9) through the wound opening, and a receiver housing (651) for receiving a seal (652) and a proximal ring (653) of the wound retractor device (2) to hold the seal (652) and the proximal ring (653) externally of the wound opening, and thus maintain a sleeve portion of the wound retractor device (2) in tension, during conveying of the distal ring (9) through the wound opening.

8. An apparatus for inserting a surgical device at least partially through a wound opening, the apparatus comprising:
-
a holder including; a proximal portion having a proximal opening, a distal portion having a distal opening, a side portion having a slot connected to the distal opening, wherein edges of the slot adjacent the distal opening diverge, and a passage configured to receive at least a portion of the surgical device; and a movable member coupled to the holder and movable relative to the holder, the movable member including; a proximal portion including a protrusion forming a proximal end, a shaft extending from the protrusion, the shaft entering the holder through the proximal opening and being slidably received in the passage of the holder, the shaft including a longitudinal axis, wherein the protrusion is aligned with the longitudinal axis, and a distal portion configured to engage the surgical device, wherein the distal portion is selectively extendable out of and retractable into the distal opening. - View Dependent Claims (9, 10, 11, 12)

13. An apparatus for inserting a surgical device at least partially through a wound opening, the surgical device including at least a distal ring and a sleeve, the apparatus comprising:
-
a holder including; a proximal portion having a proximal opening and at least one gripping protrusion extending from an outer surface of the proximal portion of the holder, a passage configured to receive at least a portion of the distal ring of the surgical device, a distal portion having a distal opening configured to allow at least a portion of the distal ring to enter into and exit from the passage, and a side portion having a slot connected to the distal opening, wherein edges of the slot adjacent the distal opening diverge, and the slot is configured to receive at least a portion of the sleeve of the surgical device; and a movable member coupled to the holder and movable relative to the holder, the movable member being movable relative to the holder between a first position allowing at least a portion of the distal ring of the surgical device to enter into the passage of the holder, and a second position for deploying at least a portion of the distal ring from the holder, the movable member including; a proximal portion including a protrusion forming a proximal end, and a shaft extending from the protrusion, the shaft entering the holder though the proximal opening and being slidably received in the passage of the holder, the shaft including a longitudinal axis, and the protrusion being aligned with the longitudinal axis of the shaft. - View Dependent Claims (14, 15, 16, 17, 18, 19)
