Harvesting the graft via medial oblique incision of left knee in the semi-flexsion position. (A) Tendon stripper (designed by W.Z.), with an opening at its neck. (B) The tendon can slide into the circle of the stripper via the gap. (C) The gap of the stripper can be closed; thus, the open tendon stripper becomes a closed tendon stripper. (D) The stripper is pushed, the front end of the stripper will peel off the tendon from the muscle. (E) The tendons are peeled intact; then, the stripper slides out without soft-tissue injury.

New tendon-lengthening technique using the tendon stripper on knee flexion contracture for a patient with cerebral palsy.
(a) The tendon of the semitendinosus muscle is identified and elevated on the medial side.
(b) The semitendinosus tendon is released from the distal to the proximal using the open tendon stripper.

Schematic illustration of the operative procedure. (A) Small saphenous vein was ligated with silk#5 below the termination of a competent gastrocnemius vein and divided. A pin stripper was inserted into the free end of the distal SSV and pushed downward. (B, C) The SSV and stripper were easily localized and grasped with mosquito forceps through a incision at the mid-calf. (D) The pin stripper was then pulled upward 2–3 cm to exteriorize the SSV and the distal portion was clamped with mosquito forceps. (E) The pin stripper was then pushed through the SSV. (F) The pin stripper was delivered along with the inverted vein through the incision at the mid-calf. SSV, small saphenous vein.

a Shadow stripper protects septum from halo particles. (Underlying simulations courtesy of JJ Yang). b Orbits of protons from shadow stripper avoid septum, and exit cleanly. Different orbits correspond to changes in stripper location in hill fringe field. c: 4-fold symmetry of magnetic field allows 4 locations for stripper foils to remove all beam from cyclotron via stripping. b and c Courtesy of L.
