Embodiment 1

[0044] Embodiment 1 A kind of osteotomy guide plate for correction surgery of body surface and lower limb deformities

[0045] An osteotomy guide plate for correction of body surface and lower extremity deformities, which includes a 3D printed osteotomy guide plate 1 attached to the skin surface of the lower extremity; fitted around the body surface of the lower extremity at the site to be operated; wherein the osteotomy guide plate 1 is set The hollowed-out opening 11 that matches the surgical incision; in addition, the osteotomy guide needle track 12 is set on the osteotomy guide plate 1, and the guide needle track 12 is integrally formed with the guide plate 3D printing; Body surface labeling structure. Through the setting of the osteotomy guide plate 1 attached to the skin of the lower extremities, the hollow opening 11 of the hollow surgical incision, the guide needle track 12 and the body surface marking structure, the osteotomy guide plate 1 can be placed quickly and ac...

Embodiment 2

[0050] Embodiment 2 A kind of osteotomy guide plate 1 for correction surgery of body surface total lower limb deformity

[0051] An osteotomy guide plate for correction of body surface and lower limb deformities, which includes a 3D printed osteotomy guide plate 1 attached to the skin surface of the lower limb; the 3D printed osteotomy guide plate 1 is a full lower limb osteotomy guide plate 1 . Applying the whole lower limb osteotomy guide plate 1 can make the corrected lower limb more conform to the mechanical characteristics of the human body. Among them, the osteotomy guide plate 1 is provided with a hollow hole 11 that matches the surgical incision; in addition, an osteotomy guide needle track 12 is provided on the osteotomy guide plate 1, and the guide needle track 12 is integrally formed with the guide plate 3D printing. The body surface marking structure corresponding to the position of the osteotomy guide plate 1. Through the setting of the osteotomy guide plate 1 at...

Embodiment 3

[0057] Example 3 A preparation method of an osteotomy guide plate for correction of body surface and lower limb deformities

[0058] A method for preparing an osteotomy guide plate for correction of body surface and lower limb deformities:

[0059] 1) In the same position as in the operation, scan the bones and skin of the lower extremities using CT thin-slice scanning. Scan to obtain digital image data of the bone and skin soft tissue of the affected limb.

[0060] 2) The digital image data is transmitted to the computer, and with the help of computer-aided design, the osteotomy site and osteotomy angle are determined in the computer according to the patient's internal bone condition; then the osteotomy line is projected to the body surface according to the determined osteotomy site's edge osteotomy line , and make a line mark, the line between the upper and lower osteotomy lines and the body surface projection mark is obtained to obtain the initial position of the skin inci...

Abstract

The invention provides a 3D printing osteotomy guide plate for body surface lower limb malformation correction operation. The 3D printing osteotomy guide plate comprises a 3D printing osteotomy guideplate body attached to the surface of the lower limb skin, and is characterized in that a hollow opening which is hollow and is anastomotic with an operative incision is formed in the osteotomy guideplate body; additionally, a needle passage of an osteotomy guide needle is arranged on the osteotomy guide plate; the needle passage of the osteotomy guide needle and the guide plate are integrally formed through 3D printing; through the arrangement of the osteotomy guide plate body attached to the lower limb skin, the hollow opening for exposing the operative incision and the needle passage of the guide needle on the guide plate, the osteotomy guide plate body can be fast and accurately placed; the incision position can be fast found; the skin is incised in an accurate position; and in addition, through the arrangement of the needle passage of the guide needle, after a bone is completely exposed, the osteotomy can be performed in a direction along the guide needle, so that the whole osteotomy process is smooth. The osteotomy guide plate can be the osteotomy guide plate for the body surface near the operation position, and can also be used for body surface osteotomy of the whole lowerlimb; and through the osteotomy guide plate for the whole lower limb, the corrected lower limb better conforms to the body mechanics characteristics.

Description

technical field [0001] The invention belongs to the technical field of surgical instruments involved in osteotomy orthopedic surgery, in particular to a medical instrument used in osteotomy corrective surgery for severe deformities of lower limbs caused by osteogenesis imperfecta, and specifically relates to an osteotomy for corrective surgery of lower limb deformities on the surface of the body Guide plate and its preparation method. Background technique [0002] Osteogenesis imperfecta (OI), also known as brittle bone disease, is a rare clinical autosomal dominant genetic disease characterized by decreased bone density and increased bone fragility. The main clinical manifestation of OI is repeated multiple fractures , scoliosis, short stature, lax ligaments, blue sclera, abnormal teeth, hearing loss, decreased lung function, heart valve disease, etc. Currently, for patients with severe deformities of the lower limbs caused by osteogenesis imperfecta, osteotomy orthopedic ...
