Surgical saw
A surgical saw for cutting bone that can be used with ease in tight places yet maintain sufficient cutting power. The surgical saw 10 has a flexible linear body made of twisted stainless steel wire and cutting parts formed on the flexible linear body. The cutting parts are made of abrasive material affixed to the flexible linear body 12 a alternating with portions of the flexible linear body with no abrasive particles 12 b . Auxiliary cutting parts 13 of lesser cutting power may be provided along both lateral sides of each of the cutting parts 12.
1. A surgical saw comprising:
a flexible linear body;
a primary cutting part adapted to cut hard tissue such as bone affixed to a portion of the flexible linear body, the primary cutting part including portions where abrasive particles are attached to the flexible linear body alternating with portions where no abrasive particles are attached to the flexible linear body, the portions with abrasive particles having a length of 1-5 mm;
secondary cutting parts each having a length longer than a length of the primary cutting part, adapted to cut hard tissue such as bone, having a coarse surface where no abrasive particles are attached to the flexible linear body, provided on both ends of the primary cutting part; and
a flexible hollow tube of synthetic resin, dimensioned to allow the flexible linear body to pass therethrough.
2. The surgical saw according to claim 1 , wherein the flexible linear body is a single strand of metal wire,
a plurality of spaced grooves is provided on the flexible linear body in the direction of the width of the flexible linear body so as to form the cutting parts therebetween,
a plurality of spaced grooves is provided on both ends of the flexible linear body in the direction of the width of the flexible linear body so as to form the auxiliary cutting parts therebetween, the grooves gently angled along both lateral sides of each such auxiliary cutting part,
the auxiliary cutting parts formed on both ends of the cutting part, at both ends of the flexible linear body.
3. The surgical saw according to claim 1 , wherein the flexible linear body is stranded wire or mesh line.
4. The surgical saw according to claim 1 , wherein at least the primary cutting part of the flexible linear body is coated with a lubricating material.
5. The surgical saw according to claim 1 , further comprising a pair of handles attached at opposed ends of the flexible linear body.
