Colorado MicroDissection Needle

Overview

The Colorado Needle is an ultra-sharp microdissection needle designed for precision cutting and coagulation. It is a single-use device intended for cutting, dissecting and cauterizing soft tissue.

Features and benefits

5 Micron tip

Ultra-fine tip creates high current density allowing for precision hemostasis at a low power setting.

Highly polished tungsten

Maintains sharpness and helps prevent tissue build-up.

Electrocautery needle

Allows simultaneous cutting and coagulation, reducing blood loss, and promoting a cleaner surgical field.

Variety of designs

Full selection of lengths and angles providing exceptional versatility for procedural and surgeon preference.

Clinical evidence

"Microneedle" electrocautery was compared against the standard-size needle electrocautery and the Shaw hemostatic scalpel to determine the differences in tissue necrosis when used as a cutting instrument. Incisions were made on the dorsal skin of anesthetized white rats using each of the three devices with the no. 15 scalpel as control. The specimens were submitted for histological evaluation. The microneedle caused less necrosis than the standard-size needle electrocautery (0.18 vs 0.27 mm, p < 0.01) and less necrosis than the Shaw hemostatic scalpel set at 220 degrees F (0.18 vs 0.25 mm, p < 0.05). The microneedle electrocautery was also found to be an instrument that causes very little tissue distortion during fine dissection and helps to minimize blood loss in craniofacial and neurosurgical operations.

PURPOSE
Diathermy is used widely in surgical procedures, mainly for subcutaneous and deeper layers dissection. The use on craniomaxillofacial skin has been precluded by the fear of scar formation, alopecia and wound dehiscence. The aim of this study was to clinically evaluate the safety of Colorado Microdissection needle (Stryker) for skin opening in craniomaxillofacial surgery.

MATERIALS AND METHODS
117 skin incisions for craniomaxillofacial procedures were performed using the Stryker Colorado microdissection needle (CMN). The incisions included Coronal, Hemicoronal, Preauricular, Subciliary, Lateral brow's, Submandibular, Retromandibular, Risdon's, Modified Blair's and Schoebinger's incision. The reason for the craniomaxillofacial operative intervention included: Craniofacial trauma, removal of benign and malignant pathology, craniofacial reconstruction and Temporomandibular joint surgeries. 115 incisions were performed in patients in the adult age group and 02 in the pediatric age group.

RESULTS
All the patients tolerated the procedures well, with no increased risk from the use of the CMN. Only one incision had wound infection and dehiscence. All other patients had usual wound healing. At 6 months follow-up postoperative scar and alopecia was evaluated. Only on close up inspection minimal area of alopecia was noticed along the incision line. The postoperative scar was healthy in all the cases.

CONCLUSION
The findings of this study recommend the use of the CMN in all craniomaxillofacial procedures.

Tonsillectomy remains one of the most common surgical procedures performed worldwide. Recent advancements in equipment technology have ushered in several new tonsillectomy techniques. Among these is the Colorado tip electromicrodissection needle. In this report, we describe the technical aspects of this modality and report our results in a prospective study of 12 adults and 13 children. We then compare our results with several published series using a variety of techniques. We found tonsillectomy using the electromicrodissection needle compares most favorably in all criteria examined, including operative and perioperative blood loss, perioperative pain, return to regular diet, and cost. We conclude that electromicrodissection tonsillectomy is an excellent option for all surgeons performing tonsillectomy.
