Spinal Surgery

Spinal surgeryCutting and coagulating the soft tissue to access the spine is the key first step in most spine surgery procedures. Our HARMONIC® Blades deliver precisely directed mechanical energy with an ultrasonic vibrating blade, making them an excellent choice for handling soft tissue. They can be used in a variety of procedures when gaining exposure to orthopedic structures (such as spine).

With the HARMONIC Combination Hook Blade, you can cut and coagulate, dissect, and spot coagulate with a single instrument. Because it uses mechanical energy to cut, rather than electricity, it produces minimal thermal spread and desiccation of tissue, as well as minimal smoke.* And blood loss is reduced by the effective first pass hemostasis.†

And when it is time to bring tissues back together, the tension on the wound and the movement of the spine can make it difficult to maintain the integrity of the wound closure. Suboptimal closure can delay healing, expose the patient to risks for infection, and lead to excess scarring.155,174,210

Ethicon offers a portfolio of wound closure products that specifically address the unique needs of spinal surgery. Innovative products such as STRATAFIX™ Knotless Tissue Control Devices, DERMABOND® Portfolio, and Plus Antibacterial Sutures can help surgeons achieve excellent outcomes by adding strength and protection to an incision.

  • * In a comparative tissue cutting study using chicken breast, the HARMONIC Combination Hooked Blade (HK105) cut at a lower tissue temperature (average temperature of 128 F or 53.3 C) compared with the monopolar electrosurgery pencil (average temperature of 230 F or 110 C). The difference was significant (p < .001).1
  • † In a vessel sealing comparison, the HARMONIC Combination Blade (HK105) sealed more 1-2 mm vessels than electrosurgery. Study conducted in porcine mesentery. In a pre-clinical study, porcine mesentery was used to compare the number of 1-2 mm vessels coagulated while cutting. The HARMONIC Hooked Blade ("HK105", power level = 5) was compared to steel scalpel and monopolar electrosurgery (power level = 40W blend 1). The steel scalpel sealed zero of 20 vessels (0%), electrosurgery sealed 3 of 70 vessels (4.3%), and HARMONIC HK105 sealed 64 out of 68 vessels (94.1%). Statistical analysis indicated that HARMONIC HK105 sealed significantly more vessels while cutting than either the steel scalpel or electrosurgery (p < .001).1
