BiZact™ Tonsillectomy Device

Overview

Less bleeding.¹^,²^,³^,†
Less tissue damage.⁴^,⁵^,⁶
More efficient tonsillectomy.^1,⁷^,⁸^,⁹^,¹⁰^,‡

The BiZact™ tonsillectomy device allows surgeons to remove tonsils efficiently, with less bleeding^1-3,† and minimal tissue damage.^4-6 So patients may experience less pain after surgery.^4-6,§

The BiZact™ tonsillectomy device is the right tool for the job — and it makes all the difference.

A procedural solution from Valleylab™ energy, the BiZact™ tonsillectomy device features:

12 cm shaft for access
Curved jaw that follows the shape of tonsil bed
Intuitive controls to seal and divide tissue and vessels up to 3 mm in diameter¹¹
Ergonomic handle for comfort in both hands

The BiZact™ device is an advanced bipolar tissue sealer and divider. It’s powered by Valleylab™ energy platforms that:

Measure impedance of clamped tissue
Adjust energy output to create a permanent seal
Automatically stop energy delivery when the seal is complete

As a result of this technology, the BiZact™ device:

Offers fast and easy setup^7,₤
Produces seals that withstand 3x normal systolic blood pressure¹⁵
Reduces bleeding during surgery^1-3,†
Improves procedural efficiency^1,7-10,‡
Minimises tissue damage,^4-6 which may reduce postoperative pain^4-6

† Average intraoperative bleeding in 17 cases was 7.3 mL for BiZact™ device, compared to published literature results for Coblator™* device (10.83 mL) and electrocautery (27.08 mL),2 and cold knife (125 mL).3
‡ Average procedure time in 17 cases for the BiZact™ tonsillectomy device was 9.35 minutes, compared to published literature results for electrocautery (14.8 minutes pediatric, 20.5 minutes adult)8 and the Coblator™* device (16.32 minutes).9
§ Low thermal damage has been shown in published studies to result in less postoperative pain. The Bizact™ device has been shown to produce <1 mm thermal spread, but has not been directly evaluated for pain reduction.
