Pelvis arcuate line lower edge anatomic bone fracture plate

Abstract

A pelvis arcuate line lower edge anatomic bone fracture plate relates to the manufacturing technology of surgical appliances and is applicable to fixing fracture of the pelvis of a human body. A plate body of the pelvis arcuate line lower edge anatomic bone fracture plate is a spatial arc-shaped curve body matching with the shape of a pelvis arcuate line lower edge anatomy surface, fixing screw holes (3) are arranged on a surface of the plate, and grooves (4) with equal strength are arranged on two sides of the plate. The pelvis arcuate line lower edge anatomy type bone fracture plate can be used as a mold plate for realizing fracture reduction of a pelvis arcuate line lower edge, is beneficial for examining a fracture reduction effect, and can meet requirements of internal fixation of pelvis inlets in different types. Intraoperative shaping consumed time is shortened by the anatomic shape of the bone fracture plate, influence to strength of the bone fracture plate due to repeated intraoperative shaping is avoided, problems that surrounding soft tissues are injured in a mold testing process and fracture reduction is lost are reduced effectively, particularly, sufferings of patients are reduced, surgical risks and complications are also effectively decreased, and pelvis fracture surgery success ratio and a therapy effect are improved.

Description

technical field [0001] The anatomical bone plate at the lower edge of the pelvic arcuate line relates to the surgical instrument manufacturing technology and is suitable for fixing human pelvic fractures. Background technique [0002] The number of cases of pelvic trauma caused by various traffic, construction and industrial accidents is increasing. Due to the special anatomical structure of the pelvis, especially the irregular arc shape of the bones at the arcuate line, it is necessary to pass through a specific surgical access window for exposure. The disorder of the anatomical structure and the rich soft tissue coverage in the operation area make the reduction and fixation operation after fracture complicated, and also lead to a high disability rate after pelvic fracture. At present, in the clinical fixation of fractures through the arcuate line of the pelvis, standard reconstruction plates are usually used to perform on-site shaping according to the anatomical shape of t...

[0002] The number of cases of pelvic trauma caused by various traffic, construction and industrial accidents is increasing. Due to the special anatomical structure of the pelvis, especially the irregular arc shape of the bones at the arcuate line, it is necessary to pass through a specific surgical access window for exposure. The disordered anatomical structure and rich soft tissue coverage in the surgical area make the reduction and fixation surgery after fractures complicated, and also lead to a high disability rate after pelvic fractures

At present, in the clinical fixation of fractures through the arcuate line of the pelvis, standard reconstruction plates are usually used to perform on-site shaping according to the anatomical shape of the arcuate line at the entrance of the pelvis to fix pelvic fractures. This surgical operation is technically difficult and time-consuming. Long and shaped steel plates are difficult to match well with the shape of the bone surface, and repeated mold trial and shaping are required, resulting in reduced strength of the bone plate, aggravated soft tissue damage during the mold trial process, and loss of fracture reduction due to mismatch between the bone plate and bone shape In addition, while increasing the operation time of the patient, the mismatch of the internal fixation may also cause secondary displacement of the fracture, increasing the risk of surgery and complications
