A BONE WAX APPI. ICATOR AND
ME'rHOD FOR DRESS ING BONE TI SSUE
ABSTRACT OF THE DISCLOSURE
An applicator for applying bone wax to bone tissue in which a layer of bone wax ~overs ~elected surface portions of a pattie of surgical fibre, and a method of applying bone wax from an applicator having a layer of bone wax covering portion~
of a pattie wherein the bone wax layer is drawn across the bone to deposit the bone wax, and the deposited bone wax is then molded over the bone tissue with exposed portions of the applicator pattie.
BACKGROUND OF THE INVENTION
FIELD OF THE INVENTION
The present invention is related to surgery and surgical procedurés and, more specifically, to surgery involving cutting of bone tissue, such as orthopedic, cardiac, and neu~rolcgical surgery, wherein bleeding of bone ti sue is to be stopped.
:
DESCRIPTION OF THE PRIOR ART
.~
Various medical, veterinary, and dental surgical pro-cedures involve the cutting of bone tissue durlng the operation.
Examples~of such procedures are laminectomies, craniotomies, ; and cardiac surgery procedures i~nvolving splitting of the sternum.
` ~ypically, the bone ~issue is~cue with a~rongeur or a saw.
., :: :

;
`: :
~, , .
As with other living tissue, bone tissue of animals and humans bleeds when it is cut. Accordingly, a means for stopping the bleeding is required. For many years, compositions generally known as bone wax have been used to dress the bone tissue and retard its bleeding. While bone wax compositions have been found that are effective, no devices or surgical pro-cedures have been developed so that the bone wax can be effec-tively and conveniently applied to the bleeding bone tissue.
Typically, surgical bone wax is sold in sterile packages that are opened at the time when the bone wax is to be applied.
The bone wax is applied to the tissue in variou~ ways. Some surgeons shape an amount of bone wax into a suitable form such as a ball and press it into the tissue either with their gloved hand or a suitable surgical instrument. When the bone wax is applied in this manner, it must then be distributed over the entire surface where the bone tissue has been cut to dress the bleeding tissue. If this ~s done with a surgical instrumen~, an incomplete distribution of bone wax sometimes results. The bone wax can be better distributed, if the surgeon uses his gloved hand to smooth the bone wax over the bleeding bone tlssue. How-ever, the~surgeon risks contamination o~ the operative field if he should tear or puncture his glov~ on the exposed bone, and risks infection of his hand as well if it is punctured by a bone spicule. Accordingly, many surgeons have used surgical patties to distribute the bone wax over the bone tissue.
Disadvantages and difficulties have appeared with all

~ ~ ~5 ~3 these prior art devices and techniques~ The p~ckage in which the bone wax is provided is small and somewhat awkward to open in a sterile operative field. Moreover, each application of bone wax required at least two steps in the surgical procedure.
In a typical orthopedic or neurosurgical operation in which bone wax is used, as many as several dozen separate applications of bone wax may be made. Therefore, the additional steps for applying bone wax consume a considerable portion of the time necessary for the operation. For example, in a neurosurgical operation requiring four hours, as much as 10 to 30 minutes may be spent in merely applying bone wax. Accordingly, a device and method for applying bone wax more efficiently and effectively would benefit the patient by lowering his exposure to possible sources of contamination, and by reducing the time that he would be under anesthesia.
SUMMARY OF THE INVENTION
The presently disclosed invention includes an applicator for applying bone wax to bleeding bone tissue, the applicator comprising a pattie of pliable surgical fibre having a layer of bone wax covering at least a portion thereof.
Preferably, the bone wax layer is disposed on one end of a surgical pattie comprised of a cotton or cotton-like material. The applica~or may be furthe~ provided with identifica~
tion means, including x-ray detectable strips, for physically or radiologically locating the applicator both during and after the operation.
Also preferably, the bone wax appl~cator is packaged in a sterile package that can be readily opened onto the surgical field.
The presently disclosed invention further includes a surgical method for dressing bleeding bone tissue with bone wax in which a bone wax layer located on a surgical fibre pattie is placed against the bone tissue and then drawn across the bone tissue such that a portion of the bone wax is deposited on the bone tissue. The deposited bone wax is then molded over the entire portion of bleeding bone ti~sue with an exposed surface of the pattie.
Other details, objects and advantages of the invention will become apparent as the following description of the preferred embodiment of the invention and the preferred method of practicing the same proceeds.
BRIEF DESCRIPTION OF THE DRAWING
Figure 1 shows a perspectlve view of the preferred embodiment of the invention; and Figure 2 shows another perspective view of the embodi-ment of Figure 1.~
PREFERRED ~MBODIMENT OF THE INVENTION
As shown~in ~igures 1 and 2, the presently preferred ~ 6~
bone wax applicator includes a pattie 10 of surgical fibre or surgical gauze. The surgical fibre can be a natural fibre, such as cotton, or a synthetic fibre, such as rayon, or a combination of natural and synthetic fibres. The term fibre, as herewith used, includes random unwoven fibres and oriented fihres, and in particular includes woven fibres such as gauze. Preferably, pattie 10 cGuld be a surgical pattie. While pattie 10 as shown in Figures 1 and 2, is generally rectangular, it could also have a square or other shape.
Covering a portion of a major surface of pattie 10 is a layer 12 of bone wax. Bone wax layer 12 can be comprised of any natural or synthetic composition that has accepted usage as bone wax. One example of uch a natural composition is Horseley's wax which includes seven parts of beeswax to one part each of alm~nd oil and fialicylic acid. While bone wax layer 12 ~an be otherwise disposed on pattie 10, it is preferred that bone wax layer 12 be located at one end thereof for the rea~on that it is believed to be easier to apply the bone wax to bleed-ing bone tissue with this arrangemen~. Al~ernatively , however, as for example where pat~ie 10 is sufficiently small that an adequate amount of bone wax would not be otherwise carried on the pattie, bone wax layer 12 can be made to cover an entire major surface of pattie 10. Surfaces of pattie 10 that are not covered by bone wax layer 12 are herea~ter referr~d to as exposed surfaces.
Preferably, the ~pplicator includes an i~entiflcation string 14 that can be used as an aid in physically locating the applicator within the ~uture. Identification 6tring 14 can be comprised of silk or othe~ suitable material. Also preferably included are X-ray strips 16 that are detectable by radiological _5_ examination and would be useful in detecting~an applicator inside the patient after the operation is completed and the sutures are closed.
The applicator is kept in sterile condition in a ~uitable package. Upon opening the package onto the operation field, the applicator is ready for immediate use without preliminar,y preparation.
In accordance with the use of the pres~ntly disclosed applicator, the applicator is placed against the bleeding bone tissue such that bone wax layer 12 is in contact with the bone tissue. The applicator is then drawn tangentially across the bone surface ~uch that bone wax is abraded from layer 12 and becomes deposited on the bone tissue. The surgeon then dresses the bone wax over uncovered areas of bone tissue by spreading the deposited bone wax with exposed portions of pattie 10.
While a presently preferred embodiment of the invention has been shown and described, and a presently preferred method of practicing the same has been illustrated, it i~ to be under stood that the invention is not limited thereto but may be other-wise variously embod:ied and practiced within the scope of the following claims.
