Pelvis arcuate line superior border anatomical bone plate

Abstract

The invention discloses a pelvis arcuate line superior border anatomical bone plate and relates to a surgical instrument manufacturing technology. The pelvis arcuate line superior border anatomical bone plate is suitable for fixing the pelvic fracture of a human body. The pelvis arcuate line superior border anatomical bone plate is a space arc curve body which is anastomotic with the shape of the inner surface of a bone at the position of a pelvis arcuate line; a fixed screw hole (3) is arranged on the plate surface; and both sides of the plate are provided with grooves (4) with the same strength. The pelvis arcuate line superior border anatomical bone plate disclosed by the invention can be used as a die plate for reduction of the pelvis arcuate line superior border fracture and is beneficial for checking the fracture reduction effect. The requirements for fixing inside different types of pelvic inlets can be met. Due to the adoption of the anatomical shape of the bone plate disclosed by the invention, the shaping time consumption in an operation is shortened; the influence of repeated shaping on the strength of the bone plate in the operation is avoided; the problems of damage to surrounding soft tissues and fracture reduction loss in the die testing process are effectively reduced; particularly, the pain of a patient is reduced; the operation risk the complications can also be effectively reduced; and the operation success rate and the treatment effect of the pelvic fracture are improved.

Description

technical field [0001] The utility model relates to an anatomical bone plate at the upper end of the pelvic arcuate line, relates to 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, straight reconstruction plates are usually used to perform on-site shaping according to ...

[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, straight 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
