Guide plate for percutaneous implantation of hollow rivets into collum femoris

Abstract

The invention relates to a guide plate for percutaneous implantation of hollow rivets into collum femoris. The guide plate comprises a guide plate body of which the inner side is of a curved surface,the upper part of the guide plate body is provided with a flange portion which is integrally formed with the guide plate body, the outer side face of the flange portion is flush with the outer side face of the guide plate body, and the thickness of the flange portion is smaller than that of the guide plate body; two groups of bolts are installed on the flange portion, the ends of the two groups ofbolts are connected with a metal baffle plate, and the metal baffle plate is located above the inner side of the guide plate body; the guide plate body is provided with a plurality of inclined guideholes, obtuse angles formed between the central axes of the inclined guide holes and a vertical line are 115 degrees, the inclined guide holes on the guide plate body is provided with a top rake, theangle of the top rake is the same as that of the collum femoris of humans, metal conduits are installed in four inclined guide holes, and the plurality of inclined guide holes can be assembled into different inverted isosceles triangles to be used as rivet-placing positions. By adopting the guide plate, the three hollow rivets can be implanted into the collum femoris quickly, accurately and effectively, fluoroscopy times are reduced, and operation time is shortened.

Description

technical field [0001] The invention relates to the field of medical auxiliary equipment, in particular to a guide plate for percutaneous implantation of a femoral neck hollow nail. Background technique [0002] Femoral neck fracture is the most common type of hip fracture. Since the femoral neck needs to undertake the movement and support functions of the human body in an upright state, its treatment effect will directly affect the quality of life of the patient in the future. [0003] At present, the main method for the treatment of femoral neck fractures is hollow nail internal fixation, that is, using three hollow nails to fix the fractured femoral head and femoral shaft together according to the patient's original physiological and anatomical structure. Its key technology is to accurately identify the physiological structure of the individual patient, and accurately implant the hollow nail into the ideal fixed position. The commonly used traditional method is to visual...

AI Technical Summary

Problems solved by technology

This method has the following disadvantages: (1) The implantation of the hollow nail depends entirely on the experience and skills of the doctor, and the positioning of the surgical instrument is difficult; (2) Usually the doctor manually holds the instrument, and the surgical instrument will shift and shake , so that the implantation position is shifted, thereby reducing the surgical accuracy and affecting the surgical quality; (3) more times of fluoroscopy, prolonging the operating time
