Embodiment Construction

[0014] In order to understand the technical solution of the present invention in more detail, the present invention will be further described below in conjunction with the accompanying drawings.

[0015] Such as figure 1 As shown, the use of the present invention At The aiming and positioning system for treating pelvic fractures comprises two identical I-shaped frames 1, two identical locators 2, a connecting rod 3, two identical fixing pins 5 and two fixing bolts 6 on the left and right. The I-shaped frame 1, the locator 2, the connecting rod 3 and the fixing bolt 6 are made of titanium alloy, and the fixing pin 5 is made of steel.

[0016] Such as figure 2 , the I-shaped frame 1 includes three parts: a square tube 1.1, a supporting round tube 1.2 and an aiming round tube 1.3. The middle part of the round pipe 1.3. The square tube 1.1 is a tubular piece with a square cross section and a wall thickness of 1 mm, and the outer length of the cross section is 8-11 mm, prefer...

Abstract

The invention relates to a device for orthopaedics operation, and particularly relates to an aimed positioning system for treating pelvis bone fracture. The aimed positioning system comprises left and right identical I-shaped racks (1), two identical positioners (2), one connecting rod (3), two identical fixing needles (5) and two fixing bolts (6), wherein each positioner comprises a first sleeve(2.1), a second sleeve (2.2) and an arc insert handle, one ends of the first sleeve (2.1) and the second sleeve (2.2) are hinged, and the two I-shaped racks (1) are connected and fixed by the connecting rod (3) to form a rectangular structure. The aimed positioning system for treating pelvis bone fracture provided by the invention has simple structure and convenience in operation.

Description

technical field [0001] The invention relates to equipment for orthopedic surgery, in particular to aiming and fixing equipment for pelvic fractures, in particular to an aiming and positioning system for treating pelvic fractures. Background technique [0002] With the development of industry and the increase in the number of motor vehicles, the incidence of high-energy pelvic fractures is increasing day by day. The minimally invasive oriented treatment of pelvic fractures and the development of biomechanics are more and more widely used in the treatment of pelvic fractures. However, in the traditional pelvic fracture surgery, after the incision, the traditional internal fixation titanium plate is installed and fixed after the fracture fragments have achieved anatomical reduction or approximate anatomical reduction through manipulation, bone traction, sledging, and top rod treatment. ; In the prevailing minimally invasive treatment today, how to apply the method of "small in...
