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.
1 . A bone material dispensing system comprising a bone material dispensing gun 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 second opening, the first opening and the second opening configured to slidably receive at least a portion of a plunger, and a tubular member comprising a proximal opening, a distal opening and a channel disposed therebetween, the proximal opening, the distal opening and the channel of the tubular member configured to receive at least the portion of the plunger; and a tray engageable with the bone material dispensing gun for loading the bone material dispensing gun with bone material, wherein the tray is engageable with a distal end of the tubular member and the plunger, and wherein the tray comprises a slot configured to receive the tubular member, a ledge on a lower surface of the tray configured to receive a portion of the plunger, an upper surface configured for dispensing the bone material, and a groove defined from the upper surface configured to receive a cannula.
2 . The bone material dispensing system of claim 1 , wherein the tubular member is movable in a first position to align the proximal opening of the tubular member with the second opening of the housing to allow the tubular member to receive at least the portion of the plunger to dispense the bone material, and the tubular member is movable in a second position to misalign the proximal opening of the tubular member with the second opening of the housing to prevent the tubular member from receiving at least the portion of the plunger.
3 . The bone material dispensing system of claim 1 further comprising 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 configured to engage a portion of the tubular member, a funnel, or a combination thereof, the locking member being movable in a locking position to lock the portion of the tubular member, the funnel, or the combination thereof with the housing.
4 . The bone material dispensing device of claim 3 , wherein the locking member is movable in a downward position, which is the locking position and an upward position, which is an unlocking position to unlock the portion of the tubular member, the funnel, or the combination thereof from the housing.
