Embodiment 2

[0104] Example 2: Extracorporeal guides for LC2 screws

[0105] The extracorporeal guiding device for LC2 screws described in this embodiment includes a locator 1 composed of two positioning pins 1.1 and two positioning bodies 1.2, a guide 2 obtained by 3D printing, a guide pin 3 and a guide pin sleeve Barrel 4.

[0106] The structures of the two positioning pins 1.1 and the two positioning bodies 1.2 and their connection methods are the same as those in Embodiment 1.

[0107] Described guide pin 3 is made of stainless steel, and its length is 300 millimeters, and diameter is 2.5 millimeters. The guide pin sleeve 4 is selected mm model, the drill sleeve has an outer diameter of 7.5 mm and a length of 150 mm.

[0108] The preparation method of the guide 2 is similar to that of Example 1.

[0109] Two positioning pins 1.1 were placed in the iliac crest 5B on the healthy side of the pelvic acetabular fracture. Under local anesthesia, the insertion point of the positioning ...

Embodiment 3

[0119] Example 3: Extracorporeal guides for anterior column screws

[0120] The extracorporeal guide device for anterior column screws described in this example, its preparation method and use method are all similar to Example 1, the difference lies in:

[0121] The guide channel 2.4 is an anterior column screw guide channel, which can be used in the fixation operation for treating anterior column fractures. The diameter of the guide pin 3 is 1.0 mm and the length is 400 mm, and the guide pin sleeve 4 is selected from mm model with an outer diameter of 7.5 mm and a length of 150 mm.

Embodiment 4

[0122] Example 4: An extracorporeal guiding device that can be used for both anterior column screws and S1 / S2 screws

[0123] The extracorporeal guide device described in this example that can be used for both anterior column screws and S1 / S2 screws, its preparation method and use method are similar to those of Example 1 and Example 3, except that:

[0124] The guide 2 also includes three guiding channels 2.4M, which are the anterior column screw guiding channel, the S1 screw guiding channel and the S2 screw guiding channel, which can respectively pass through the anterior column screw, S1 screw and S2 screw. The diameter of the guide pin 3 is 1.0 mm and the length is 400 mm, and the guide pin sleeve 4 is selected from mm model with an outer diameter of 7.5 mm and a length of 150 mm.

Abstract

The invention provides a passage bolt extracorporeal guiding device for pelvic and acetabulum fractures and methods for manufacturing and using the same. The passage bolt extracorporeal guiding devicefor the pelvic and acetabulum fractures comprises a locator, a guider acquired by 3D printing, a guide needle and a guide needle sleeve which sleeves outside the guide needle, guide passages are arranged on the guider, and the guide passages comprise one or more of an acetabulum front column bolt guide passage, an acetabulum back column bolt guide passage, an ilium bolt guide passage, an acetabulum upper bolt guide passage, a sacroiliac bolt guide passage and a transsacral bolt guide passage. The passage bolt extracorporeal guiding device is accurate in locating and can be applicable to treating various types of pelvis and acetabulum fractures. The methods for manufacturing the passage bolt extracorporeal guiding device for the pelvic and acetabulum fractures and using the passage bolt extracorporeal guiding device are simple and easy to operate, the locating is accurate, and the device and methods are applicable to promotion.

Description

technical field [0001] The invention relates to the field of orthopedic medical devices, in particular to an external channel screw guiding device for pelvic and acetabular fractures and a method thereof. Background technique [0002] Due to the complex anatomy of pelvic acetabular fractures, there are many adjacent important tissues and organs, and the types of fractures are ever-changing. Traditional open reduction and internal fixation can directly look at the injured area, which is conducive to anatomical reduction. However, during the open operation, the soft tissue is exposed too much, the operation is complicated, and it is easy to damage important blood vessels and nerves. Therefore, the operation of pelvic and acetabular fractures is difficult. , Time-consuming, more bleeding, high risk. [0003] At present, closed reduction and minimally invasive screw technology has gradually become the mainstream of treatment for pelvic acetabular fractures. The pelvic acetabul...
