Problems solved by technology

However, there is a technical learning curve in the specific operation of osteotomy orthopedics. The osteotomy angle and bone grafting method are designed by measuring the angle between the mechanical axis of the proximal and distal humerus or the cubitus valgus angle before surgery.
[0003] At present, high-fidelity dummy has been used in the medical field. Doctors can train the proficiency of surgery by simulating exercises on the dummy. However, in the specific training operation, it includes osteotomy position, osteotomy end angle maintenance and internal fixation. Material placement, it is difficult to achieve the ideal position to simulate the pre-operative design

Embodiment 1

[0043]Embodiment one, such as Figure 1 to Figure 10 as shown,

[0044] A percutaneous navigation device for distal humerus osteotomy correction, comprising a first steel needle group 51 vertically fixed on the humerus distal body segment 73 and a second steel needle group 52 vertically fixed on the humerus proximal body segment 71, the first steel needle group The group 51 is perpendicular to the mechanical axis of the far body section 73, and the second steel needle 52 group is perpendicular to the mechanical axis of the proximal section 71; it also includes the first seat body 1 and the second seat body 2 arranged side by side along the length direction of the humerus, the first seat body The body 1 is provided with the first support member 61 as the swing fulcrum of the first steel needle group 51, and the first seat body 1 is provided with a first angle scale line 112 in the swing stroke of the first steel needle group 51, and the second seat body 2 There is a second sup...

Embodiment 2

[0050] Embodiment two, such as Figure 11 and Figure 12 as shown,

[0051] The structure of the second embodiment is similar to that of the first embodiment, the difference is that the movable joint includes a first bolt 32 which is arranged on the second seat body 2 in the circumferential direction, and a first bolt 32 which is arranged on the first seat body 1 in the circumferential direction. Two bolts 33 , the first base body 1 is provided with a first threaded hole 13 threaded with the first bolt 32 , and the second seat body 2 is provided with a second threaded hole 23 threaded with the second bolt 33 . Rotating the first bolt 32 can make the first seat 1 move toward the second seat 2, and rotating the second bolt 33 can make the second seat 2 move toward the first seat 1. The first bolt 32 and the second The bolts 33 have the same structure, and usually the first bolt 32 and the second bolt 33 are rotated synchronously during use, which can prevent the whole device f...

Embodiment 3

[0052] Embodiment three, such as Figure 13 , 14 and Figure 15 as shown,

[0053] The structure of the third embodiment is similar to that of the second embodiment, except that the first toggle piece 41 and the second toggle piece 42 are sliders respectively, and the first toggle piece 41 is temporarily fixed to the first seat body 1. The first temporary positioning device; the second toggle member 42 is provided with a second temporary positioning device temporarily fixed on the second seat body 2 .

[0054] In the embodiment, the first temporary positioning device includes a first stud 412 arranged on the first toggle member 41, and a first nut 413 screwed on the first stud 412, and one end of the first nut 413 is set On the first seat body 1; the second temporary positioning device includes a second stud 422 arranged on the second toggle 42, and a second nut 423 screwed on the second stud 422, the second nut 423 One end is set on the second base body 2 . Rotate the fi...

Abstract

The invention discloses a distal humerus osteotomy orthopedic percutaneous navigation device. The distal humerus osteotomy orthopedic percutaneous navigation device includes a first steel needle groupvertically fixed on a distal part of the humerus and a second steel needle group vertically fixed on a proximal part of the humerus, and further includes a first base body and a second base body which are arranged side by side in the length of the humerus, the first base body is provided with a first supporting member as a swing fulcrum of the first steel needle group, the first base body is provided with a first angle scale line in the swing travel of the first steel needle group, the second base body is provided with a second supporting member as a swing fulcrum of the second steel needle group, the second base body is provided with a second angle scale line in the swing travel of the second steel needle group, and a movable connector is arranged between the first base body and the second base body. The invention further discloses an operating method. Compared with the prior art, in the simulated surgery training, the guide is accurate, the surgical incision is small, the iatrogenicinjury is low, operation time is short, the simulated amount of bleeding is few, and the simulated pain and the surgical scar are less.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to the correction of the humerus in simulation teaching, in particular to a percutaneous navigation device for osteotomy and correction of the distal humerus and an operating method thereof. Background technique [0002] During orthopedic surgery, varus deformities in children caused by irregular treatment of supracondylar fractures, especially those involving the stability of the medial column of the humerus, may be encountered in children. It has been reported in literature that the incidence of cubitus varus caused by supracondylar fractures in children reaches 60%. . Cubitus varus deformity not only affects the aesthetics of the patient, but may also cause ulnar neuritis or humeroulnar arthritis in the later stage. Therefore, once a child is found to have cubitus varus > 20°, it is recommended to perform osteotomy on the affected side to correct the cubitus varus Turn deformit...
