AND DEVICE FOR tunneling microfracturing subchondral bone

摘要

The invention relates to medicine, namely to traumatology and orthopedics.; The purpose of the utility model: Create a design that allows ream subchondral bone without causing trauma to soft tissues of the joint, under the control of the insertion depth of the tool and easily extract needles from bone.; An apparatus for tunneling and microfracturing subchondral bone comprises a K-wire with labels, a spring and a cannula handle, wherein the K-wire length corresponds to the length of the cannula. Inside the cannula is a needle marks and emphasis. Between the cannula and an abutment on the needle wears spring. The distance between the marks - 1 mm. label length - 4 cm distance between the blunt end of the spokes and the stopper -. 1.5 cm. The length of the spring - 3 cm.; The technical result of the proposed utility model: Improving the blood supply of the subchondral bone and the creation of conditions for filling defects of articular cartilage regenerate.
