Novel symphysis pubis dissection bone fracture plate and design method thereof

Abstract

The invention discloses a novel symphysis pubis dissection bone fracture plate and a design method thereof, and relates to the field of medical apparatus and instruments. The novel symphysis pubis dissection bone fracture plate comprises a bone fracture plate main body, the two ends of the bone fracture plate main body are connected with two bone fracture plate supporting arms, six first oval common screw holes are formed in the bone fracture plate main body in a penetrating mode, two first round locking screw holes and a second oval common screw hole are formed in each bone fracture plate supporting arm in a penetrating mode, a plurality of first pre-bending grooves are formed in the side face of each bone fracture plate supporting arm, a side arm structure is fixedly connected to the side face of the bone fracture plate main body, and the bone fracture plate main body, the bone fracture plate supporting arms and side arms are integrally designed. According to the novel symphysis pubis dissection bone fracture plate and the design method thereof, the pelvis anterior ring injury can be stereoscopically fixed by means of the cooperative use of common screws and locking screws, and the fixing stability is greatly improved; and the bone fracture plate can assist the pelvis anterior ring in fracture reduction, shorten the operation time, reduce the operation wound and promote the accelerated rehabilitation of a patient through different designs of the size and the shape of the bone fracture plate.

Description

Technical field[0001]The invention relates to the field of medical equipment, in particular to a new type of pubic symphysis anatomical bone plate and a design method thereof.Background technique[0002]Tile B pelvic injury is characterized by unstable rotation, no significant displacement in the vertical direction, lateral displacement of more than 1 cm caused by rotation violence can be seen on the plain X-ray film, after clinical examination, special position X-ray plain film , CT and other examinations can be diagnosed. Rotational instability can be divided into two types: external rotation (type B1) and internal rotation (type B2). Among them, the common mechanism of Tile B1 pelvic injury is the anteroposterior violent squeezing of the pelvis or the external rotation of the hip joint. Under the action of external force, the pubic symphysis is separated, the upper and lower branches of the pubic bone are fractured, and the pelvis is rotated outwardly, that is, unidirectional. Or a...

Problems solved by technology

Among them, the common mechanism of Tile B1 type pelvic injury is the extrusion of the pelvis by force in the anteroposterior direction or the external rotation force of the hip joint. Under the action of external force, the pubic symphysis is separated, the upper and lower ramus of the pubic bone is fractured, and the pelvis is rotated and displaced outwards, that is, one-way Or bidirectional "turning book-like" injuries, like opening a book, often use corresponding fixation devices to fix the pelvis during treatment. Traditional fixation devices have poor stability in the treatment of Tile B pelvic injuries. Moreover, the surgical trauma is relatively large, which is not conducive to the recovery of patients. Therefore, we propose a new type of anatomical bone plate of the pubic symphysis and its design method to solve the above problems
