The present invention is directed to systems, methods, tools and surgical procedures that provide for improved, faster and/or more efficient methods for cleaning bone of soft tissue in preparation for use in bone grafting and surgery, including specific applications particularly useful in fusion procedures and/or other surgeries of the lumbar, cervical, and/or thoracic spine and/or other anatomical locations, desirably allowing for faster and complete healing.

Bone cleaning tool

The present invention is directed to providing a sterile container protecting various surgical grafts, implants and devices from incidental contamination and damage during operative procedures. The design includes an inner box to contain the items, and an outer box to protect the exterior of the inner box from contamination in the event of fall or other contamination, such as from airborne particles or liquids, fall from the sterile field, or by non-sterile handling. In the event of fall or contamination of the outer box, the surgical staff will be able to recover the inner box and its contents in sterile and unspoiled condition without difficulty.

Protective box for surgery

The golf club also has a crown component composed of a plurality of plies of pre-preg material and a sole component composed of a plurality of plies of pre-preg material. The golf club head is manufactured using a bladder compression molding process.

Method of manufacturing a composite golf club head

A golf club ( ) having a club head ( ) with a face component ( ) and an aft body ( ) is disclosed herein. The face component ( ) has a striking plate port ion ( ) and a return portion ( ). The aft-body ( ) is composed of a crown portion ( ), a sole portion ( ) and optionally a ribbon section ( ). The face component ( ) is composed of a metal material, and the aft-body ( ) is preferably composed of a non-metal material such as a composite material or a thermoplastic material. The face component ( ) is bonded to the aft-body ( ) with a leading edge ( ) of an undercut portion ( and ) of the aft-body positioned a distance of 0.100 inch to 0.500 inch from the interior surface ( ) of the face component ( ) in order to reduce the stress on the bonded joint of between the face component ( ) and the aft-body ( ). The club head ( ) has a volume in the range of 290 cubic centimeters to 600 cubic centimeters, a weight in the range of 165 grams to 300 grams, and a striking plate portion ( ) surface area in the range of 4.00 square inches to 7.50 square inches.

A golf club having a club head composed of a composite material and having an enhanced sound during impact with a golf ball. The golf club head also has a coefficient of restitution greater than 0.8 under test conditions such as the USGA test conditions specified pursuant to Rule 4&mdash;1e, Appendix II, of the Rules of Golf for 1998-1999. The golf club head body has a weight strip placed within a ribbon of the body. The sound of the composite golf club head during impact with a golf ball is approximately equivalent to that of a metal wood during impact with a golf ball. The composite golf club head of the present invention has a combined sound level greater than one hundred seventeen decibels during impact with a golf ball.

Sound enhance composite golf club head

A golf club head composed of a composite material and having a plurality of weight members in a ribbon section is disclosed herein. The weight members are composed of a polymer material integrated with a high density metal such as tungsten. Each of the weight members preferably has a mass ranging from 5 grams to 25 grams. The golf club head is preferably composed of plies of pre-preg sheets. The club head preferably has a volume ranging from 175 cubic centimeters to 600 cubic centimeters.

Internal weighting for a composite golf club head

A golf club having a club head with a striking plate composed of a composite material and having a thickness in the range of 0.010 to 0.250 inches is disclosed herein. The golf club head also has a coefficient of restitution greater than 0.8 under test conditions such as the USGA test conditions specified pursuant to Rule 4-1 , Appendix II, of the Rules of Golf for 1998-1999.
