Abstract

The invention discloses an in-vitro dynamic hip screw guider comprising guide needle cannulas and a guide block. The guide block is provided with a bottom edge and guide edges. The bottom edge is provided with two parallel puncture needles. The bottom edge is provided with a plurality of guide needle holes parallel to the guide edges. The guide needle cannulas are inserted into the guide needle holes. With the in-vitro dynamic hip screw guider, the positioning operation in needle passing and fixation for femoral intertrochanteric fracture and femoral neck fracture is simplified, a needle feeding point can be positioned quickly and accurately, and the needle feeding angle can be kept quickly and accurately; the guider has the advantages of avoidance of heavy wound, high cost, radiation and the like; through using the guider, the number of photographing or raying times is reduced, surgical time is shortened, surgical bleeding is less, and patients feel less pain; in addition, the guider guarantees safety and reliability of operation and is simple in structure, easy to disassemble, convenient to carry, economical, practical and suitable for final popularization and application.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an extracorporeal dynamic hip screw guide. Background technique [0002] At present, human society is aging, and fractures of femoral neck and femoral trochanter are common and frequently-occurring diseases of the elderly. DHS internal fixation for intertrochanteric fractures is a commonly used surgical method at present. One of the key operations in the operation is to place a positioning guide pin, which determines the position and direction of the screw in the femoral neck and plays an important role in the success of the operation. However, due to the special anatomical structure of the femoral neck, there are neck-shaft angles and anteversion angles on different planes, and the position is deep and concealed, making it difficult to place the positioning guide pin correctly. When clinical internal fixation is used to treat femoral neck and femoral trochanter frac...
