Internal anterior pelvic ring fixation plate

Abstract

The invention belongs to the technical field of medical instruments for orthopedics use, and specifically discloses an internal anterior pelvic ring fixation plate. The internal anterior pelvic ring fixation plate comprises a head part, a neck part, a trunk part and a tail part which are sequentially connected in a fixed way; 3 rows of head locking holes are arranged at the middle of the head part, so that locking screws can be placed in an area adjacent to the pubic symphysis; the neck part is a junction area which connects the head part and the trunk part in different planes; a neck notch isarranged above the neck part; a trunk locking hole is arranged at the middle of the trunk part, so that a locking screw can be inserted into the superior pubic branch; and a trunk notch is arranged above the trunk part; a locking hole is arranged on the tail part along an acetabulum notch, so that a channel screw can be inserted into a junction area of the ilium and the pubis. The internal anterior pelvic ring fixation plate has the following beneficial effects: the internal anterior pelvic ring fixation plate is capable of effectively fixing anterior pelvic ring fracture, so that the internal anterior pelvic ring fixation plate is suitable for pubic fracture, especially for pubic fracture near the pubic symphysis; design of the fixation plate makes fixation of the pubic fracture near thepubic symphysis more reliable; and moreover, fixation across the pubic symphysis is not required, so that loss of pubic symphysis functions can be avoided. Therefore, the internal anterior pelvic ring fixation plate is especially suitable for unmarried women for performing spontaneous delivery.

Description

technical field [0001] The invention belongs to the technical field of orthopedic medical devices, in particular to an internal fixation bone plate for an anterior pelvic ring, in particular to the internal fixation treatment of pubic fractures. Background technique [0002] Pubic fractures are the most common pelvic fractures, and internal fixation is required for pubic fractures that affect pelvic stability or cause persistent pain. The main purpose of the operation is to restore the symmetry and stability of the pelvic ring, allow patients to perform functional exercises as soon as possible, promote the functional recovery of surrounding tissues and organs, and reduce bed-ridden complications. For pubic fractures, especially those near the pubic symphysis, the bone fragments in the medial pubic bone are too small to be fixed with ordinary reconstruction plates without crossing the pubic symphysis. [0003] According to the prior art, the internal fixation of pubic fractu...
