Abstract

The invention provides a personalized pelvic support positioning device which comprises a sacrum positioning part, an L-shaped connecting rod, an arc-shaped connecting rod, an ischium positioning part and a pubis positioning part, one end of the L-shaped connecting rod is connected with the bottom end face of the sacrum positioning part, and the other end of the L-shaped connecting rod is connected with the pubis positioning part; one end of the arc-shaped connecting rod is connected with one side surface of the sacrum positioning part, and the other end of the arc-shaped connecting rod is connected with the ischium positioning part; the device has the advantages that the technical defects that in the prior art, the structure is single, the number of faces attached to a patient is small, soft tissue on the surface of a skeleton cannot be cleaned up in an operation, and large errors are prone to being generated through a single positioning face are overcome; the positioning device disclosed by the invention can be applied to auxiliary navigation in personalized semi-pelvic prosthesis surgery for pelvic tumor cases separated from sacroiliac joints.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a personalized pelvic support positioning device. Background technique [0002] The pelvis is a basin-shaped skeleton that connects the spine and the lower limbs. It is a complete bone ring formed by the connection of the rear sacrum, coccyx (the two lowest bones of the spine) and the left and right hip bones. The pelvic ring is also the only way for important blood vessels, nerves and reproductive system to pass through, so serious damage to the pelvic ring will not only lead to high mortality and disability rates. Early reduction and fixation can improve the prognosis. [0003] Although the integrated guide plate in the prior art can be used for positioning and assisting treatment during the operation, there are still technical defects such as single structure, large error, and poor stability. Contents of the invention [0004] The present invention provides a per...
