Embodiment

[0050] see figure 1 and figure 2 , the amputee in the illustration is a specific embodiment of the present invention, including a base 10, a jigsaw bracket 20, a jigsaw 30, a jacking strut 40, a limb fixing mechanism 50, a crank reciprocating mechanism 60, a motor 70 and Width adjustment screw mandrel 80. Wherein the base 10 is the main body base of the amputee, and two groups of wire saw brackets 20 are relatively arranged on the base 10, and the wire saws 30 are connected in a ring and are wrapped around the pulley blocks arranged on the two groups of wire saw brackets 70, and there is always a section The wire saw is overlapped between the tops of the two groups of wire saw brackets, and the amputated limbs are pressed on the section of wire saw between the two groups of wire saw brackets, so that the entire wire saw ring is tensioned; the motor 70 is connected to the wire saw 30 through the reciprocating mechanism Connection, through the motor drives the reciprocating m...

Abstract

The amputation device comprises a base, a fret saw support, a fret saw, a jacking supporting rod and a motor. The two groups of fretsaw brackets are oppositely arranged on the base, the fretsaws are connected into a ring and are wound on pulley blocks arranged on the two groups of fretsaw brackets, a section of the fretsaw is always lapped between the tops of the two groups of fretsaw brackets, and an amputated limb is pressed on the section of the fretsaw between the two groups of fretsaw brackets, so that the whole fretsaw ring is tensioned; a jacking pulley of the pulley block is installed on the top of the fret saw support through a jacking supporting rod, the fret saw bypasses the jacking pulley to be in lap joint with the top of the fret saw support, the fret saw support is provided with a jacking spring which pushes the jacking supporting rod upwards, the fret saw is always kept in a tensioning state, and the motor is connected with the fret saw through a reciprocating mechanism. And the tensioned wire saw ring is driven by the motor to do reciprocating motion so as to drag and saw limb bones pressed on the wire saw. The amputation device can improve the amputation operation effect, saves the physical output of the operation, and can be widely popularized and applied in the bone surgery amputation operation.

Description

technical field [0001] The invention relates to an amputation device, which belongs to orthopedic amputation surgical instruments. Background technique [0002] The procedure of amputation is generally to cut the skin first, usually making a fish mouth flap incision, cutting off the muscles, nerves, and ligation of blood vessels at both ends of the incision, sawing off the relevant bones, removing the limb, and then Suture the stump. [0003] Among the existing amputation instruments, tools for sawing off bones include blade saws, bar saws and wire saws. During the process of sawing off bones, tissues such as skin, muscles, blood vessels and nerves around the bones are free near the bones. Rigid saw blades or saw blades are easy to cause damage to the surrounding tissue of the bone, affecting the suture of the subsequent stump, while the flexible wire saw can fit the bone well for sawing, and can avoid frictional contact with the surrounding tissue of the bone to the greate...
