Problems solved by technology

In traditional orthopedic surgery osteotomy, there is no special medical equipment to assist in positioning the osteotomy. The operator generally judges and selects the osteotomy position based on experience and the surface characteristics of the lesion, so it is easy to cause large trauma and the osteotomy position is not accurate. , difficulty in surgical planning, etc.

Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings.

[0015] Such as figure 1 , figure 2 As shown, a limb bone osteotomy navigation device for precise positioning is composed of a positioner 10 made of medical polylactic acid (PLA) material and an osteotomy guide plate 20 .

[0016] The body part of the locator 10 includes a central column 11, and the side of the central column 11 is provided with three connecting rods 12 extending in the radial direction. The distribution of the metal positioning pieces 14 and the positioning columns 13 preferably forms a triangular distribution. A sub-column 16 is provided on the upper surface of the central column 11, and a connecting rod 15 is additionally provided on the side of the sub-column 16 to connect to the navigation post 17. The anti-twist hole 18 is provided on the navigation post 17 as an interface for assembling the osteotomy guide plate.

[0017] The osteotomy guide ...

Abstract

The invention discloses a limb bone cutting navigation device capable of realizing accurate locating, and belongs to the field of medical equipment. The device is assembled with a locator and a bone cutting guide plate. The locator is provided with a plurality of metal locating sheets. The bone cutting guide plate includes a first substrate, a second substrate, and a bridging plate connecting the first substrate and the second substrate from above. The first substrate is provided with an anti-twisting pile matching an anti-twisting hole of the locator. The bone cutting guide plate is of an assembled structure, so that the bone cutting guide plate can cooperate with medical equipment in accurate locating. Consideration is given to both financial cost and the locating flexibility and accuracy in shape design of the locator. The bone cutting guide plate ensures the accuracy and security of nail implanting and knife advancing from multiple aspects.

Description

technical field [0001] The invention relates to the field of medical equipment under 3D printing technology, in particular to a navigation device for extremity bone osteotomy that realizes precise positioning. Background technique [0002] Osteotomy surgery is generally performed for the correction of bone deformities, bone tumors, and severe bone trauma. In traditional orthopedic surgery osteotomy, there is no special medical equipment to assist in positioning the osteotomy. The operator generally judges and selects the osteotomy position based on experience and the surface characteristics of the lesion, so it is easy to cause large trauma and the osteotomy position is not accurate. , Surgical planning is difficult and other issues. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a navigation device for extremity bone osteotomy that realizes precise positioning. [0004] ...
