Insertion of the Provox® Vega™ prosthesis using the Puncture Set™
The new Puncture Set for the Provox® Vega™ prosthesis has been available in Germany since June 2011. It can be used for the primary insertion of a voice prosthesis following laryngectomy or for secondary insertion, and is a development of the widespread system consisting of puncture trocar, pharynx protector and guide wire.
A mechanism for the automatic unfolding of the tracheal prosthetic flange when drawing the prosthesis into the shunt is a significant improvement that greatly simplifies and accelerates the intraoperative shunt placement and primary insertion of the prosthesis. Another improvement is the atraumatic dilatation of the puncture canal after the shunt puncture and before insertion of the voice prosthesis.
The Provox® Vega Puncture Set™ consists of a Provox® Vega prosthesis (1) that is attached to a puncture dilator (2), a blue plastic guide wire (3), a bent puncture needle (4) and a small transparent pharynx protector (5), also made of plastic. The pharynx protector is only to be used for insertion of a voice prosthesis in laryngectomy. For secondary insertion, the Puncture Set may be used in conjunction with a rigid oesophagoscope or pharyngoscope.
The materials of the Provox® Vega Puncture Set™ are all sterile disposable products. The Puncture Set is available with Provox® Vega prostheses in diameters 17 Fr, 20 Fr and 22.5 Fr and in shaft lengths 8 mm, 10 mm and 12.5 mm; the 17 Fr Set is also available in 15mm.
