Closed reduction device for unstable pelvic fracture minimally invasive surgery

Abstract

The invention discloses a closed reduction device for unstable pelvic fracture minimally invasive surgery. The closed reduction device for unstable pelvic fracture minimally invasive surgery comprises a first lateral outer frame, a second lateral outer frame, a connecting outer frame, guide rails, a guide rail sliding clamp, an outer frame sliding clamp, screws and a screw clamp, wherein the second lateral outer frame is smaller than the first lateral outer frame and arranged inside the first lateral outer frame, and the first lateral outer frame and the second lateral outer frame are fixed to the guide rails through the guide rail sliding clamp; the connecting outer frame is of the structure that the arc part is connected with transverse straight rod parts, the arc part and the transverse straight rod parts are not arranged on the same plane, and the transverse straight rod parts at the two ends of the arc part are coaxially arranged in the same plane; the connecting outer fame is connected with the second lateral outer frame through the outer frame sliding clamp; the screw clamp is used for clamping the screws and fixed on the connecting outer frame. The guide rails are arranged on two sides of an operation bed. The closed reduction device for unstable pelvic fracture minimally invasive surgery can recover an unstable pelvic fracture according to a specific route, a specific angle and specific parameters, the reduction effect is good, and pain of a patient is small.

Description

technical field [0001] The invention belongs to the field of surgical medical instruments, in particular to a closed reduction device for minimally invasive surgery of unstable pelvic fractures. Background technique [0002] The human pelvis is a circular structure, which can be divided into the anterior ring composed of the pubic bone and the posterior ring composed of the sacroiliac joint complex. The posterior ring is an important link for bearing body weight and conducting body biomechanics. Involvement of the posterior ring can be divided into stable pelvic fractures and unstable pelvic fractures. [0003] The pelvis contains important organs and blood vessels and nerves that innervate the lower limbs, and the important nerves and blood vessels of the pelvis are mostly concentrated near the posterior pelvic ring. Once the posterior pelvic ring is damaged, it will easily lead to death and disability of the patient. It has been reported in the literature that the fatal a...

Problems solved by technology

[0008] In order to solve the defects of traditional pelvic fracture reduction that requires repeated fluoroscopy, large amounts of radiation, open surgery to expose too much soft tissue, large wounds and easy infection, the present invention provides a reset that can reset unstable pelvic fractures according to a specific path, specific angle and specified parameters. mechanism
