An Innovative Method of Collecting Autologous Bone Fragments During Surgery

About An Innovative Method of Collecting Autologous Bone Fragments During Surgery

The Hensler Bone Press (HBP) is a medical device that collects and separates blood from autologous bone to be used during bone fusion procedures. It was designed and developed to bring an end to the antiquated and inefficient method of collecting drilled bone fragments in fusion cases found in most operating rooms across the country, and to reduce cost, time and greatly enhance patient care.

The HBP is now patent-pending to be used in conjunction with ultrasonic devices as a second indication of use.  The sterile evacuation tubing attaches seamlessly with the HBP collection chamber.  Included in each HBP kit is the attachment piece required to attach the OR provided suction tubing to the silicon tubing.  The collection chamber attached to the sterile drape allowing for little to no interruption of the case between full container transfers.  This process allows for the STERILE collection and separation of abnormal pathology, such as malignant tumors, used commonly by neurosurgeons, OB/GYN surgeons, general and oncological surgeons. 

The Hensler Bone Press is simple, yet remarkably advanced. Using this device, a surgeon is able to deliver the patient’s own bone back to their body, thereby reducing the need to rely on expensive synthetic bone substitutes and biologics. Respectively, when used as an auxiliary device attachment to the various ultrasonic devices on the market, the HBP now provided the sterile collection of tissue while cutting costs and improving tissue diagnosis.

ADVANTAGES: Bone Fusion Application

  • Allows for maximum use of patients’ autologous bone for re-implantation during a fusion case, which is the gold standard for bone fusion.

  • Reduces the need to rely on expensive synthetic bone material (allograft and biologics), which may or may not successfully fuse when compared to autologous bone.

  • Dramatically decreases the amount of time spent gathering and prepping bone harvesting during surgery, which in turn will keep the staff focused on the actual surgery at hand.

  •  Disposable and cost-effective

  • Delivers clinically proven viable bone cells.  Bone substitute is generally calcium based product and a simple scaffolding matrix. The bone the HBP is collecting is live, patient specific bone with the ability to fuse on its own.

ADVANTAGES: Ultrasonic Application

  • Collects and separates abnormal tissue from blood and irritants STERILE.

  • Attaches seamlessly with ultrasonic evacuation tubing.

  •  Less pathology billing time required, given tissue sent to pathology, is free of contaminants and significant clotted blood, which can make tissue diagnosis much more difficult.

Typical Bone Collection: The current technique used to collect valuable bone fragments today involves either harvesting from a donor site or a technician sifting through material by hand to find and save bone to be used for fusion. This process is messy, inefficient and time-consuming as techs may spend up to thirty minutes finding valuable bone particles. Average time in the OR is anywhere from $25 – 50/minute.  Loss of bone is afforded. Further, the technician and surgical assistants can rarely capture the finer particles of bone that may still be salvageable.

The Use of Synthetic Bone: Synthetic options for bone grafts are expensive and can cost between $250-2000 for a small supply. Biologics can cost from $1500-6000 each case.  Many times, biologics are even used off-label.  As with any foreign substance, there is a potential of rejection in the patient’s body, which could result in infection, a longer recovery time and a greater chance of increased surgeries and hospital stays due to pseudoarthrosis (non-union).

The Use of Autologous Bone: The patient’s own bone is universally preferred to allow for optimal fusion during bone grafting procedures. Autologous bone contains inherent properties most synthetics and biologics do not. The unique properties of autologous bone is osteoinduction and osteoconduction.  Osseointegration is most likely with the patient’s own autologous bone.

A Revolutionary Method: By increasing the proficiency of collecting and utilizing the patient’s own bone, the Hensler Bone Press not only improves the surgical procedure in terms bone collection and separation, but also increases the quality of patient care. It reduces cost, time and risks in the surgery suite. Unlike other products available on the market, the Hensler Bone Press both collects the patient’s bone material and delivers an immediately usable end product in a proven 2-step method to effectively improve many facets of traditional fusion procedures.
