BONE MATERIAL DISPENSING SYSTEM WITH LOCKING MEMBER
A bone material dispensing device is provided. The bone material dispensing device comprises a housing having a proximal end, a distal end, and a longitudinal axis. The proximal end having a first opening and the distal end having a second opening. The first opening and the second opening configured to slidably receive at least a portion of a plunger. A locking member is provided that is pivotably connected to an upper surface of the housing and extends adjacent to the upper surface of the housing. The locking member comprises a locking surface extending adjacent to the distal end of the housing configured to engage a portion of a tubular member, a funnel, or a combination thereof. The locking member is movable in a locking position to lock the portion of the tubular member, the funnel, or the combination thereof with the housing. A bone material dispensing system and a method of implanting bone material with the bone material dispensing system are also provided.
Curable Material Dispensing System And Methods Of Operating And Packaging The Same
A system for dispensing curable material. A lead screw is rotatably fixed relative to a first control surface and includes external threads. A locking nut includes internal threads threadably engaging the external threads. An engagement feature of the locking nut is adapted to be selectively engaged with an actuator having a second control surface. The threads provide for rotation of the locking nut about a translation axis when the actuator is in a disengaged position. Rotation of the locking nut permits the lead screw to move proximally along the axis and the compressed curable material to at least partially decompress within a dispensing volume. The threads further provide for distal advancement of the lead screw along the axis when the actuator is in an engaged position rotatably fixing the locking nut about the axis. Methods for operating and packaging the curable material dispensing system are also described.
ORTHOPAEDIC SURGICAL INSTRUMENTS FOR DIRECT ANTERIOR APPROACH HIP ARTHROPLASTY AND METHODS OF USE
Orthopaedic instruments for use in a direct anterior approach orthopaedic surgical hip replacement procedure on a patient's femur are disclosed. One such orthopaedic instrument may be embodied as a cement nozzle sized for insertion in a medullary canal of the patient's femur. The cement nozzle may include a first lumen for introducing a bone cement composition into the medullary canal. The cement nozzle may also include a second lumen for removing one or more bodily fluids from the medullary canal during introduction of the bone cement composition. The first and second lumens may each be curved along a distal portion of the cement nozzle.
NAVIGATION INSTRUMENTS FOR SUBCHONDRAL BONE TREATMENT
An instrument for navigating to a target area near a subchondral defect of a bone and associated methods are disclosed. The instrument can include a body portion having a patient specific surface defining a negative impression of a portion of a skin surface of a patient, and a targeting device coupled to the body portion, the targeting device including a rail and at least one device portal configured to guide a device into a subchondral region of the bone for treatment at the target area.
KYPHOPLASTY SYSTEM AND METHOD
A kyphoplasty system includes various instruments which can be selectively used in a surgical theater (e.g., during a surgical operation on a patient) or a surgical training environment. The kyphoplasty system can include one or more of a kyphoplasty apparatus, a prone table mat, a connector system, a bone introducer needle, and a biopsy device. The kyphoplasty system may also include a training system for use in the training environment.
STORAGE AND MIXING DEVICE FOR PRODUCING A BONE CEMENT
A storage and mixing device for PMMA bone cements having a cylindrical interior of the cartridge that is delimited on a front side by a cartridge head with a closed delivery opening, a plunger which is arranged to be axially movable in the cylindrical interior of the cartridge and which is spaced from the cartridge head. The plunger circumferentially rests against the inner wall of the interior, so that the plunger divides the interior of the cartridge into two sections in a gas-tight manner, a powdery first parent component of the bone cement, which is contained in the interior between the plunger and the cartridge head, a feed-through which is arranged in the cartridge head or in the cylinder barrel of the cartridge between the plunger and the cartridge head, wherein the feed-through is connected to a fluid line in which a monomer liquid as a second parent component of the bone cement is contained or into which a monomer liquid is fillable or introducible. A filter is arrangeable in the cartridge head, in the feed-through and/or in the fluid line, wherein the filter is permeable to the monomer liquid and impermeable to the first parent component, wherein the plunger is spaced from a back side of the cylindrical interior, located opposite the front side, to an extent that, by moving the plunger in the direction of the back side, a reduced pressure is producible in the interior of the cartridge between the plunger and the cartridge head, wherein the reduced pressure is able to suck the monomer liquid out of the fluid line into the interior of the cartridge.
Bone treatment systems and methods
A system for delivering bone cement into a bone is provided. The system can include a hydraulic system actuatable to deliver a bone cement mixture from a bone cement container, through a cannula and into a bone. The hydraulic system can have more than one pressure relief mechanism for decreasing pressure in the hydraulic system to cease delivery (e.g., substantially instantaneously) of the bone cement into the bone.
DISPENSING SYSTEM AND METHOD
A dispensing system includes a device having a body extending along a longitudinal axis between opposite proximal and distal ends. The body includes a proximal chamber, a distal chamber and a wall between the chambers. The body includes a first port in communication with the proximal chamber and a second port in communication with the distal chamber. A shaft is movably positioned within the body. The shaft extending through the wall and comprising a proximal plunger positioned within the proximal chamber and a distal plunger positioned within the distal chamber. Wherein pressure introduced through an opening in the proximal end moves the shaft such that the proximal plunger moves a material within the proximal chamber out of the first port and the distal plunger moves a material within the distal chamber out of the second port. Kits and methods of use are disclosed.
DISPENSING SYSTEM AND METHOD
A delivery system is provided that includes a device having a body extending along a longitudinal axis between proximal and distal ends. The body includes a proximal chamber, a distal chamber and a wall between the chambers. The body includes a first port in communication with the proximal chamber and a second port in communication with the distal chamber. A shaft is movably positioned within the body. The shaft extends through the wall and includes a proximal plunger positioned within the proximal chamber and a distal plunger positioned within the distal chamber. Pressure introduced through an opening in the proximal end moves the shaft such that the proximal plunger moves a fluid within the proximal chamber out of the first port and the distal plunger moves a fluid within the distal chamber out of the second port to simultaneously actuate a bone filler dispenser. Systems and methods are also provided.
Multichannel cannula and methods for using same
A method for delivering a substance to bone includes placing a stabilizing wire in a bone, creating a hole in the bone around the stabilizing wire, and providing a multichannel cannula. The multichannel cannula includes a first channel having an open proximal end and distal end, the first channel being configured to receive the stabilizing wire, and a second channel having an inlet portal and an exit portal that are in fluid communication. The cannula further includes a cap having a delivery port in fluid communication with the inlet portal and a channel for receiving the cannula therein, and a distal tip. The method further includes inserting the multichannel cannula into the hole in the bone such that the first channel receives the stabilizing wire, and delivering the substance into the bone by introducing the substance into the second channel such that the substance exits through the exit portal.
