Bone material dispensing device

Abstract

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 has a first opening and the distal end has a second opening. The first opening and the second opening are configured to slidably receive at least a portion of a plunger. A tubular member is provided that is pivotably connected to the housing and is configured for lateral movement relative to the longitudinal axis of the housing. The tubular member comprises a proximal opening, a distal opening and a channel disposed therebetween. The proximal opening, the distal opening and the channel of the tubular member are configured to receive at least the portion of the plunger. 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. A method of implanting bone material with the bone material dispensing device is also provided.

Description

Background technique [0001] Various devices and methods have been used to apply bone material, such as bone graft, to a surgical site. Bone grafts are important in orthopedic surgery for repairing bone defects caused by injury, disease, wound or surgery. For this reason, a number of materials have been used or proposed for use in repairing bone defects. The biological, physical and mechanical properties of a material are major factors affecting its suitability and performance in various orthopedic applications. [0002] Typically, regeneration of bone tissue is achieved by filling the bone defect with bone material (eg, bone graft). Over time, the bone graft is resorbed by the host, and new bone remodels the bone graft. Bone material may comprise bone from the patient's own body, synthetic bone material, natural substitute bone material, or combinations thereof. [0003] To deliver bone material to a bone defect, the bone material is typically mixed with a liquid or therap...

AI Technical Summary

Problems solved by technology

Further, the transfer of bone material to the dispensing device is often accomplished through rough and messy packaging of the bone dispensing device, which causes undesired waste and spillage of bone material

These devices may also increase the risk of contamination of bone material during its transfer and delivery

Additionally, some dispensing devices may cause damage to surrounding tissue at the surgical site during application of the bone material

Also, bone material may clog certain dispensing devices due to its consistency and / or due to the design of the dispensing device, and when this occurs, the amount of bone material cannot be effectively controlled
