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 comprising a frame having a front wall, a back wall, and an air gap, the back wall having a back opening and the front wall having a second opening such that the first opening, the back opening and the second opening are configured to slidably receive at least a portion of a plunger, the front wall comprising a generally flat contact surface configured to engage a funnel; and a locking member pivotably connected to an upper surface of the housing and extending adjacent to the upper surface of the housing, the locking member comprising a locking surface extending adjacent to the distal end of the housing, the locking member being movable in a locking position to lock the portion of the funnel with the housing. A bone material dispensing system and a method of implanting bone material with the bone material dispensing system are also provided.
A bone material dispensing device comprising a housing having a proximal end, a distal end, and a longitudinal axis, the proximal end having a first opening and the distal end comprising a frame having a front wall, and a back wall, the back wall having a back opening and the front wall having a second opening such that the first opening, the back opening and the second opening are configured to slidably receive at least a portion between a proximal end and a stopper of a plunger, the front wall comprising a generally flat contact surface configured to engage a funnel such that a portion of the funnel is connected to the housing, the funnel including a ledge configured to retain a folding cannula such that the folding cannula cannot exit through a distal end of the funnel.
A method of dispensing a bone material, the method comprising loading a bone material dispensing device with the bone material via a funnel and/or a cannula, the bone material dispensing device comprising 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 frame comprising a second opening, and a back opening, the first opening, the back opening and the second opening configured to slidably receive at least a portion of a plunger between a proximal end and a stopper of the plunger, and a funnel such that a portion of the funnel is connected to the housing, aligning the funnel with the second opening and the back opening of the frame and stabilizing the funnel by engaging a portion of the funnel with the front opening, the funnel including a ledge configured to retain a folding cannula such that the folding cannula cannot exit through a distal end of the funnel, and the funnel configured to receive at least the portion of the plunger to dispense the bone material.
