Pelvic traction approximator

Abstract

The invention discloses a pelvic traction approximator, which comprises a left connection rod, a right connection rod, an adjustor component, two traction approximator arm components and two pressurizing bone plate components. The two pressurizing bone plate components are connected to top positions of the left connection rod and the right connection rod respectively. Two ends of the adjustor component are connected to middles of the left connection rod and the right connection rod respectively. The two traction approximator arm components are connected to bottom positions of the left connection rod and the right connection rod respectively. An adjustor is used for adjusting a distance of an inner screw rod screwed into the inner wall of a sleeve. The pelvic traction approximator has advantages that by inner and outer fixing devices, pelvic traction is performed according to a distraction osteogenesis technique without osteotomy, occlusion of separated pubic symphysis of patients suffering from ectopocystis is realized, surgical risks are reduced, postsurgical effects similar to those of an osteotomy mode are achieved, and the treatment effective rate is increased; in addition, postsurgical abnormal gaits of patients are prevented, and approximately normal walking and urination of the patients after surgeries can be realized.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a pelvic traction closer. Background technique [0002] Epispadias-bladder exstrophy is a relatively rare but very serious type of congenital malformation of the genitourinary system. It is often combined with separation of the pubic symphysis. The malformation involves the urinary system, reproductive system, skeletal muscle system, pelvis, pelvic floor and soft tissue of the abdominal wall. It is very difficult to treat clinically, causing huge functional and morphological obstacles to patients, and often unable to live a normal life. [0003] The surgical sequence of bladder exstrophy includes functional bladder repair (separation correction of pubic symphysis, closed everted bladder, bladder neck compaction), repair of abdominal wall soft tissue defect and urethral defect, and repair and reconstruction of external genitalia. Among them, correction of cong...

Problems solved by technology

Obviously, the traditional technique uses pelvic osteotomy and steel wire internal fixation; the above-mentioned traditional method of osteotomy and internal fixation has high surgical risks, such as nonunion and bleeding, and its therapeutic effect is not necessarily good.
