Problems solved by technology

However, due to the poor strength distribution of the structure of this osteotomy saw, the osteotomy saw breaks when the osteotomy is performed.
Additionally, the semi-circular osteotomy saw does not allow for fine angle adjustments

Abstract

The invention relates to a spherical bone-cutting pendulum saw head. The spherical bone-cutting pendulum saw head comprises a connecting device, a first saw web and a second saw web, wherein a first end of the first saw web is connected with the connecting device; a first end of the second saw web is connected with a second end of the first saw web, the second saw web and the first saw web are connected in an L-shape, and a plurality of saw teeth are arranged on a second end of the second saw web; the inner surfaces of the first saw web and the second saw web form a spherical arc surface; andthe connecting device, the first saw web and the second saw web are integrally formed. The invention further relates to a spherical bone-cutting pendulum saw. The spherical bone-cutting pendulum saw has the advantages that the inner surfaces of the first saw web and the second saw web form a spherical arc surface, the spherical bone cutting is achieved under the action of the reciprocating power,the broken end of the cut fractured bone is spherical, and the end surface of the cut fractured bone is smooth and level; the spherical bone-cutting pendulum saw is favorable for fine control in the osteotomy, the contact surface of the end surface of the cut fractured bone is maximized, the spherical bone-cutting pendulum saw is favorable for the fixation after the bone cutting, and the related complications are reduced.

Description

technical field [0001] The invention relates to the technical field of osteotomy devices, in particular to a spherical osteotomy oscillating saw head and a spherical osteotomy oscillating saw. Background technique [0002] Osteotomy orthopedic treatment is a common surgical method in orthopedic clinic. The existing osteotomy orthopedic treatment mostly uses a conventional osteotomy pendulum saw for osteotomy, and the plane of osteotomy is usually a plane. This kind of osteotomy usually has certain problems. For example, when the angle is adjusted, the osteotomy end is usually A gap is generated, which in turn leads to an uneven osteotomy plane, which is likely to cause poor fracture healing, weak fixation, and fracture of the fixation. [0003] In order to solve the above problems, the existing osteotomy pendulum saw is improved to obtain a semicircular osteotomy saw. However, the structure of this osteotomy saw has a problem of fracture of the osteotomy saw when the osteo...
