Systems and methods for preparing a ligament graft for a ligament reconstruction procedure are provided. In general, the described techniques utilize a graft preparation system having a holder and a delivery suture assembly removably coupled thereto. The delivery suture assembly can include a spine coupled with an anchor suture configured to form a self-tightening knot used to position the assembly around a graft and a plurality of suture windings configured to be affixed to the graft when the assembly is deployed. The assembly is delivered to the graft using the holder and the sutures can be affixed to the graft without penetrating therethrough. The spine helps to evenly distribute the load among the windings compressing the graft which are thus are capable of withstanding increased loads. Thus, an improved, simplified, and time- and labor-saving approach to preparing ligament grafts is provided.

Systems and methods for ligament graft preparation

A surgical instrument includes a body assembly, a waveguide, a transducer, and a coupling assembly. In some versions the coupling assembly translates the transducer to couple the transducer to the waveguide. For instance, a gear having arcuate troughs may engage pins on the transducer and/or waveguide to mate the transducer to waveguide. A pawl may selectively engage and prevent rotation of the gear. Alternatively, lever arms may cam the transducer into the waveguide. The lever arms may selectively couple to a casing to prevent decoupling of the transducer and waveguide. In another configuration, a locking tab can be slid and locked into a slot to couple the transducer and waveguide. Further still, levers with self-locking pins may engage and couple the transducer to the waveguide. In another version, a rotatable body portion may engage a tab on the transducer to rotate and couple the transducer to the waveguide.

A handle assembly for a handheld surgical instrument is disclosed. The handle assembly may include a body portion extending parallel to a longitudinal axis, a fixed handle interfaced with the body portion and extending downwardly from the body portion and away from the longitudinal axis, and a detachable handle portion. The fixed handle may define a proximal contact surface. The detachable handle portion may define an internal surface configured to interface with the proximal contact surface of the fixed handle and comprise at least one attachment feature to removably couple the detachable handle portion to the fixed handle.

Ergonomic surgical instruments

A surgical instrument can comprise a first jaw and second jaw, wherein the first jaw is movable relative to the second jaw to capture tissue having a tissue thickness. A tissue cutting force monitor is configured to determine the tissue thickness of the captured tissue and communicate the tissue thickness to a controller, wherein the controller is configured to adjust the speed of a tissue-cutting element during a cutting portion of a firing stroke based on the tissue thickness communicated from the tissue cutting force monitor. The controller is configured to reduce the speed of the tissue-cutting element when the tissue cutting force monitor communicates a thicker tissue thickness to the controller. The controller is configured to increase the speed of the tissue-cutting element when the tissue cutting force monitor communicates a thinner tissue thickness to the controller.

Surgical instrument

A perforation instrument and method of using same, including a shaft capable of being inserted into a joint of a patient, having a longitudinal axis, and carrying at least one piercing member, each piercing member having a tip suitable to pierce sub-chondral bone. The instrument is capable of being altered between an exposed condition wherein the tip of the at least one piercing member is exposed and a safety condition wherein the tip of the at least one piercing member is not capable of piercing tissue.

Instrument and method to enhance articular cartilage regeneration

A surgical instrument including a trigger configured to be actuated by a proximally directed force and by a distally directed force. The trigger may include a proximal trigger portion having a first length and a distal trigger hook comprising a distal portion having a second length. The second length may be less than the first length. The distal trigger hook may be coupled to the proximal trigger portion.

Methods and devices are provided for forming holes in bone to stimulate bone growth. In one exemplary embodiment, a surgical instrument set can include a driver having a first mating element, and a bone pick have a second mating element configured to releasably mate with the first mating element at any of a plurality of angular orientations. When releasably mated together, the driver and the bone pick can be configured to be adjustably positioned relative to one another with three degrees of freedom, e.g., pitch, yaw, and roll. The bone pick can include a piercing tip configured to form a hole in a bone, such as in microfracture. When the driver and the bone pick are releasably mated together, the driver can be configured to be struck, impacted, or otherwise manipulated to drive the piercing tip into the bone.

A surgical instrument comprising a trigger configured to be actuated by a proximally directed force and by a distally directed force. The trigger may comprise a proximal trigger portion having a first length and a distal trigger hook comprising a distal portion having a second length. The second length may be less than the first length. The distal trigger hook may be coupled to the proximal trigger portion.

A surgical instrument for supplying energy to tissue can comprise a jaw member comprising an electrode, wherein the electrode is configured to supply energy from a power source to captured tissue. The surgical instrument comprises a tissue-cutting element to transect the captured tissue. The rate of distal translation of the tissue-cutting element during the operational stroke may be regulated by a damper. The damper may have barrel and a plunger.

Electrosurgical cutting and sealing instrument

A needle targeting apparatus comprises a sense head configured to locate an implanted device and a guide. The guide is associated with the sense head and comprises an upper surface, a lower surface, and a support member. The support member comprises a channel extending through the support member that provides access to an injection site. In some versions, a needle targeting apparatus comprises a locating feature, an alignment feature, and a support feature. The locating feature is configured to locate an implanted device. The alignment feature is configured to align a syringe needle with the implanted device. The support feature is configured to support a syringe upon insertion of the syringe needle into the implanted device. In some versions, a needle targeting apparatus comprises a sense head configured to locate an implanted device and a guide. The guide is configured to identify the center of the sense head.
