Securing device to secure fixation devices to bone portions

Abstract

The present invention discloses a securing device that is used to secure a fixation device to two bone portions to promote healing between the two bone portions. The bone portions commonly include a skull bone portion and a skull bone flap or implant, and the fixation device is commonly a cranial clamp. The securing device provides for securing the fixation device in a uniform, single movement asopposed to currently available products. The securing device has two handles pivotably connected, and a gripping means moveably associated with one handle. As the handles are activated, the gripping means travels proximally along the one handle and grips an elongated section of the fixation device and exerts a tensioning force along the shaft of the elongated section prior to the cutting means cutting the elongated shaft to secure the fixation device in place.

[0003] The present invention relates to an instrument for use with a fixation device for soft tissue-to-bone or bone-to-bone fixation, such as the fixation of a bone flap or bone implant to bone. Background technique

[0004] There have been various surgical procedures that require the fixation of soft tissue to bone or bone to bone in order to produce healing, such as the fixation of bone flaps or bone implants to a patient's skull. For example, craniotomy is a surgical procedure used to treat various brain injuries, including treatment of tumors and aneurysms. As part of the craniotomy procedure, the surgeon makes an opening in the skull. One technique is to drill a number of adjacent holes to define the perimeter of the opening and then use a tool to ...
