SPINE CAGE HOLDER
A cage holder includes an elongated body having a proximal end and a distal end, the elongated body extending from the proximal end to the distal end. The cage holder further includes means for transferring energy centrally from the proximal end to the distal end through the elongated body.
BONE PUNCH INSTRUMENT
A medical device configured to form one or more holes within a bone of a patient may include a handle assembly including a housing, a lever rotatably coupled to the housing, and a sheath extending distally from the housing, the handle assembly including a spring biasing the lever toward an initial or intermediate position; and a bone punch including an elongate shaft, a head at a proximal end of the elongate shaft, and a piercing tip at a distal end of the elongate shaft configured to be driven into the bone. The elongate shaft may be slidably disposed within the sheath in a first position when the lever is in the initial or intermediate position. Translation of the bone punch distally within the sheath from the first position to a second position may cause a distal end of the lever to rotate away from the housing to an extended position.
Spine cage holder
The present invention concerns a cage holder including an elongated body comprising a proximal end and a distal end, the elongated body extending from the proximal end to the distal end. The cage holder is characterized in that it further includes means for transferring energy centrally from the proximal end to the distal end through the elongated body.
TENSIONABLE AND LOCKABLE MICRO SUTURE ANCHORS AND ANCHOR ARRAYS FOR ANATOMICAL ATTACHMENT OF SOFT TISSUE TO BONE
A toggle-type suture anchor that incorporates individual suture tensioning and locking without knot tying. The anchor includes several exemplary designs of toggle bodies having a working suture pre-threaded through one or more passages therethrough. A locking suture loop is pre-threaded relative to the working suture and includes a collapsible loop that encircles a portion of the length of suture running longitudinally adjacent the side of the anchor. With the loop open, the working suture can slide through the anchor, however, when the loop is closed the working suture is locked in position to retain tension on the working suture. Alternatively, the locking suture loop can be replaced with a mechanical locking member that moves from a first unlocked to a second locked position. The exemplary anchors can be utilized in a pre-strung connected array of anchors.
INDIVIDUALLY LOCKABLE CINCH LOOP MICRO SUTURE ANCHOR ARRAY FOR HIGH DENSITY ANATOMICAL ATTACHMENT OF SOFT TISSUE TO BONE
A system of toggle type suture anchors is disclosed. The plurality of suture anchors is connected in series by a plurality of independently cinchable working suture loops with one working suture loop connecting each pair of anchors in series to form a chain. Each of the suture anchors as connected by working suture loops allows tensioning of the working suture between itself and the prior anchor implanted in the serial string. Further, each anchor includes a loop type locking mechanism to lock the cinchable working suture loop subsequent to tensioning so that the loop remains fixed in size during cyclic loading during joint use. This creates an independently tensioned suture stitch between each implanted suture anchor and the just previously implanted anchor. In total the system as implanted creates a high density, continuous array of anchor-to-anchor stitches for robust securement of soft tissue to bone.
Rotary Impactor for Orthopedic Surgery
A rotary impactor for orthopedic surgery includes an output anvil and a hammer that is capable of imparting linear and rotary force on the anvil. The anvil may be moveable on a leadscrew element to alternately generate energy in an energy storage means and to move along the leadscrew element to impact the anvil. A viscoelastic mechanism or a dampening mechanism is used to reduce the reflected force and or torque during operation of the rotary impactor. High frequency linear impacts by the impactor obviate the need for a surgeon to provide an external push force on the impactor in order to perform a successful surgical operation.
IMPACTOR
There is disclosed an orthopaedic impactor, comprising: a strike assembly arranged to impart a force to an object; and a winding arranged to receive a current and thereby generate a magnetic field. The winding is arranged to interact with the strike assembly so that, in use, a magnetic field generated by the winding causes the strike assembly to move so as to impart the force to the object.
LOCKING SUTURE CONSTRUCT FOR TENSIONED SUTURE TO SUTURE STITCHES IN ANCHOR ARRAYS FOR ATTACHING SOFT TISSUE TO BONE
An assembly and method are provided for incorporation into suture anchor designs to facilitate the locking of a slidable working suture after it has been tensioned. The assembly can be utilized on multiple anchors in a pre-strung chain on a single working suture to create continuous, individually tensioned suture bridges between anchors in series, without knot tying. Further, the bridges are independently locked with selected tension for the particular application. An anchor body having at least one suture receiving passage therethrough is threaded with a working suture wherein the working suture flosses through the passage when tension is applied to the working suture. A locking cord extends through a second passage through the anchor body, the locking cord having a collapsible loop extending out the second passage and encircling a portion of the working suture, wherein collapsing the loop locks the working suture after tensioning.
ORTHOPEDIC IMPACTOR TOOL
Disclosed herein are orthopedic impact tools and methods of use thereof. The orthopedic impact tools can include a housing, a tube assembly, a reverse impact plate, an anvil and an impact mechanism. The housing can include a hand grip portion and an impact mechanism housing portion. The tube assembly can include a first tube portion and a second tube portion. The reverse impact plate can be disposed in between the first tube portion and the second tube portion. The anvil can include a forward impact surface. The impact mechanism can include a motor, a piston, a ram, and a rotary to linear conversion mechanism drivingly connecting the motor to the piston. The piston can be disposed within the first tube portion and the ram can be disposed in the second tube portion and movable into contact between the reverse impact plate and the forward impact surface.
