Based on the foregoing, it can be appreciated that, in the embodiment of the auxiliary femoral fracture reduction device 1000 provided by the invention, before use, the auxiliary femoral fracture reduction device is in the second position, that is, a certain included angle is formed between the right side surface of the first semicircular femoral clamping piece 10 and the left side surface of the second semicircular femoral clamping piece 20, then the two-section fractured femoral head is pulled by the lifting hook 3000 so as to lift and tilt up to be in an inverted V shape, and then the two lifting hooks 3000 correspondingly penetrate through the first notch groove 101 and the second notch groove 201 from bottom to top, so that the inner top surface of the first semicircular femoral clamping piece 10 abuts against the top wall of one section fractured femoral head, and the inner top surface of the second semicircular femoral clamping piece 20 abuts against the top wall of the other section fractured femoral head, and then the two required lifting hooks 3000 are lifted, and simultaneously the first semicircular femoral clamping piece 10 and the second semicircular clamping piece 20 are pressed down, so that the first semicircular femoral clamping piece 10 and the second semicircular clamping piece 20 are positioned.
Because the inner diameter of the first semicircular femur fastener 10 is equal to the inner diameter of the second semicircular femur fastener 20, and both the inner diameter and the outer diameter of the fractured femur end are matched, when the first semicircular femur fastener 10 is positioned at the corresponding first position, the circle center of the first semicircular femur fastener 10 and the circle center of the second semicircular femur fastener 20 are necessarily positioned on the same straight line, two sections of fractured femur 2000 ends are not easy to form after growing together when being lifted and tilted, no matter misplaced or not, when the two sections of fractured femur 2000 ends are synchronously pressed down, the two sections of fractured femur 2000 ends can be correspondingly clamped in the first semicircular femur fastener 10 and the second semicircular femur fastener 20 after being stressed, so that the two sections of fractured femur 2000 ends can be effectively ensured to be aligned accurately on the same straight line after being pressed down, the two sections of fractured femur 2000 ends are not easy to form after being connected and fixed by intramedullary nails, the two sections of fractured femur 2000 ends are not easy to cause good reset effect, the fracture is easy to cause trouble, the fracture is easy to be lifted and the two sections of fractured femur 2000 ends are easy to be lifted and stopped, the fracture is easy to be lifted and stopped, the operation is easy to be carried out, and the operation is greatly is easy, and the operation is easy to save the operation is convenient, and the operation is time-saving is greatly convenient, and the operation is easy to be convenient, and easy to use and easy to operate is convenient to use and easy to operate.
Furthermore, the invention has strong practicability and good use effect.
Here, it should be noted that when the two fractured femur 2000 ends of the patient are precisely aligned and on the same straight line after being pressed down, the used bone lifting hook 3000 can be directly removed upward from the first notch groove 101 and the second notch groove 201, and then the two fractured femur 2000 ends can be connected and fixed by using an intramedullary nail.
In addition, in the implementation, if the distance between the two bone lifting hooks 3000 is large and it is difficult to pass through the first notch groove 101 and the second notch groove 201 from bottom to top, the first semicircular femur fastener 10 and the second semicircular femur fastener 20 may be detached so that the first semicircular femur fastener 10 and the second semicircular femur fastener 20 move from the outer walls of the two-stage fractured femur 2000 to the ends thereof, and then they are connected and fixed so that the two bone lifting hooks 3000 pass through the first notch groove 101 and the second notch groove 201 from the side.
In addition, in the implementation, after the two sections of femur 2000 ends of the fracture are connected and fixed by using the intramedullary nail, the two sections of femur 2000 of the fracture of the patient can be directly taken out from the operation opening above the femur of the patient, and the two sections of femur 2000 of the fracture of the patient can be reset from top to bottom through the operation, so that the peeling of the skin surface tissues of the patient can be reduced, and the trauma is reduced.
Further, in the present technical solution, the width of the first semicircular femur fastener 10 and the width of the second semicircular femur fastener 20 are both D; the d=2.0 cm-7.0cm.
Preferably, in the present embodiment, the width of the first semicircular femur fastener 10 and the width D of the second semicircular femur fastener 20 are both set to 4.0cm, so that the two-stage fracture femoral 2000 end is not too wide to be conveniently placed from the operation opening of the femur 2000 of the patient and not too narrow to be conveniently assisted in reduction.
In addition, in the implementation, the invention further comprises a first operation handle 30 for controlling the first semicircular femur fastener 10 and a second operation handle 40 for controlling the second semicircular femur fastener 20;
the lower end of the first operating handle 30 is vertically connected with the left middle part of the upper top surface of the first semicircular femur fastener 10, and is preferably welded; the lower end of the second operating handle 40 is vertically connected with the right middle part of the upper top surface of the second semicircular femur fastener 20, and is preferably welded;
thus, when the first operation handle 30 and the second operation handle 40 are held by hand, the force is facilitated, and the control of the present invention is more flexible.
Preferably, in the present technical solution, the outer diameter of the upper end of the first operating handle 30 is larger than the outer diameter of the lower end thereof; the outer diameter of the upper end of the second operation handle 40 is larger than that of the lower end thereof; and the outer wall of the upper end of the first operating handle 30 and the outer wall of the upper end of the second operating handle 40 are provided with anti-skid lines.
