A trocar system is provided which preferably includes a cannula having an elongate cannula body. The cannula body includes medial and distal portions thereof having a first diameter and a proximal portion thereof connected to the medial portion and having a second diameter. The second diameter is preferably larger or greater than the first diameter. A trocar having an elongate trocar body also extends through the cannula. The elongate trocar body has a sharpened distal end portion, a medial portion thereof having a first diameter, and a proximal portion having a second diameter. The second diameter is preferably larger or greater than the first diameter. The trocar also has a handle connected to a proximal end portion of the trocar body for gripping of and handling of the trocar by a hand of a user and a shield slidably mounted to the medial portion of the trocar body and biased in an extended position so that a distal end of the shield coveringly protects the sharpened distal end of the trocar body until pressure is applied thereagainst so that the shield slidably moves toward the proximal portion of the trocar body in a retracted position. The shield has a third diameter which is preferably at least equal to or less than the second diameter.

A trocar system is provide which preferably has a cannula having an elongate cannula body. The cannula body includes medial and distal portions thereof having a first diameter and a proximal portion thereof connected to the medial portion and having a second diameter. The second diameter is preferably larger or greater than the first diameter. A pair of finger grips are each connected to and extending outwardly from the proximal portion of the cannula body for gripping the cannula with the fingers of a hand of a user. A trocar having an elongate trocar body is positioned to extend through the cannula body. The trocar also having a handle connected to the trocar body for gripping of and handling of the trocar by a hand of a user.

Combined obturator, cannula and valve assembly

A system for inserting a cannulated tissue anchor during endoscopic surgical procedures. The system incorporates an elongated generally cylindrical tissue anchor having a plurality of barbs outwardly extending from its body and a transverse head situated at its proximal end. The head is elongated along a major axis which is misaligned relative to the rows of barbs on the body of the tissue anchor in order to enhance retention of the anchor within selected tissue. The anchor may be inserted during an endoscopic surgical procedure by a single-handed operation utilizing an instrument having a longitudinally slidable needle for guiding the anchor into place and a longitudinally slidable push rod for pushing the anchor along the needle. The system incorporates a package/loading device to facilitate the assembly of a cannulated tissue anchor with the inserter, the package/loading device being provided with a means for guiding the inserter needle through the axial bore of the tissue anchor.

Cannulated tissue anchor system

An instrument and method for manipulating an operating member during a surgical procedure. The operating member has suture attached thereto and is supported at a distal end of the instrument. Tension is maintained on the suture material while the operating member is manipulated. For example, the operating member can be a suture anchor that is inserted through a hole formed in hard tissue and oriented to span the hole while tension is maintained on the suture material.

A system for inserting a cannulated tissue anchor during endoscopic or other surgical procedures. The system incorporates an insertion instrument for inserting into a surgical site of implantation an elongated generally cylindrical tissue anchor having, for example, a plurality of barbs outwardly extending from its body and a transverse head situated at its proximal end. The anchor may be inserted by a single-handed operation of the instrument through a series of sequential pulls of a trigger, each pull affecting motion of a particular element. In a preferred embodiment, three trigger pulls are sufficient to penetrate the site of implantation and deliver the anchor slidably along the needle. The instrument operates with replaceable subassemblies each containing a particular size cannulated anchor, having a longitudinally slidable needle for guiding the anchor into place and a longitudinally slidable push rod for pushing the anchor along the needle.

A surgical screw driver for inserting bone screws in bone tunnels in ligament reconstruction has, in a preferred embodiment, a rotatable operating shaft disposed at an angle to a drive shaft. A mechanism is on the drive shaft for retaining a bone screw. Methods of arthroscopic cruciate ligament reconstruction include the steps of introducing a surgical screw driver through a portal that is offset from the longitudinal axis of a bone tunnel and driving a bone screw mounted on the driver in the bone tunnel to fixate a bone block in the bone tunnel.

A cannulated bioabsorbable tack has annular ribs configured to enhance fixation to tissue, such as bone, and is particularly effective for attaching soft tissue to bone, such as ligaments or muscles in the shoulder. Apparatus and method for displaying the tack facilitate arthroscopic surgical procedures for attaching or joining tissue.

Bioabsorbable tack for joining bodily tissue

A cannulated bioabsorbable tack has annular ribs configured to enhance fixation to invivo tissue and is particularly effective for attaching soft tissue to bone, such as ligaments or muscles. Apparatus including a trocar wire, an inserter and an impactor facilitates arthroscopic surgical procedures for inserting the tack invivo to attach or join the tissue.

An apparatus for repairing in vivo torn cartilaginous or other bodily tissue, particularly torn meniscus tissue during arthroscopic surgery, employs a repair tack of biodegradable material chosen to have a degradation time in excess of the required healing time for the tissue. The repair tack has a shaft portion with a longitudinal bore and a grip portion adapted for releasable engagement by a hollow applicator. In one embodiment the grip portion of the tack is a cross bar, at the proximal end of the shaft, which fits into an open-sided slot at the forward end of the applicator.
