Cutting and coagulating the soft tissue to access the spine is the key first step in most spine surgery procedures. Our HARMONIC SYNERGY^® 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 SYNERGY^® 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.^†

At Ethicon Endo-Surgery, Inc., we believe innovation is the key to providing better care for patients.  Using the input of hundreds of surgeons, we’ve refined our HARMONIC SYNERGY Blades to make them easier to use, more ergonomic and as effective as possible. This has helped make them a trusted device in more than 10 million procedures worldwide.

* 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
