Bunnell Tunnel Instrument

Description

Bunnell Tunnel Instrument

The Bunnell tunnel instrument creates a path through tissue so a tendon can reach its new position. At 23 cm, it suits the hand and forearm.

Making a tunnel

Tendon transfers often route the tendon under skin or through fascia. Therefore the surgeon first opens a channel with this instrument. The tendon then follows the channel.

Hand surgery roots

Sterling Bunnell developed many techniques for tendon transfer. In addition, this tunneler reflects that practical approach. Also, its smooth shaft parts tissue with little damage.

Who uses the Bunnell tunnel instrument

Hand surgery is its main field, especially transfers around the wrist. Similarly, plastic surgeons use it for flap and graft routing. It also fits pediatric hand sets.

Routing the tendon

Advance the tip along the planned line from the far incision to the near one. Once it emerges, fix the tendon end to it. Then draw it back so the tendon slides into place.

Length

At 23 cm, the instrument reaches across the forearm. Consequently, it handles most hand transfers. Longer routes need a longer tunneler.
