Embodiment 1

[0031] A navigation module for taking iliac bone blocks in finger reconstruction surgery, including a navigation module 1, with no less than three navigation holes 2 evenly distributed around the navigation module 1, and the diameter of the navigation holes 2 is 1 mm.

[0032] A method for preparing a navigation module of an iliac bone block taken in finger reconstruction surgery, the specific steps are:

[0033] The first step is to collect CT data of both hands of the target object, and perform 3D reconstruction to obtain a virtual 3D model of both hands;

[0034] The second step is to import the data of the 3D model of the virtual hands obtained from 3D reconstruction into the 3D printer, and print out the physical models of the hands;

[0035] The third step is to measure the length and circumference of the missing finger on the physical model of both hands;

[0036] The fourth step is to draw a sketch of the module of the missing finger in the 3D rendering software;

[...

Embodiment 2

[0048] Compared with embodiment 1, when the patient's hand joints are damaged, the diameter of the navigation hole 2 is 1.2mm.

[0049] In this way, the present invention can be better fixed and prevented from falling off or shifting.

[0050] The purpose of the present invention is to provide a navigation module and a preparation method for removing iliac bone blocks in finger reconstruction surgery. The shape of the iliac bone block that meets the reconstruction requirements is adjusted to reduce the operation time and reduce the damage to the patient.

Abstract

The invention discloses a finger reconstruction operation ilium block fetching navigation module and a preparation method thereof. The navigation module for fetching ilium blocks through 3D printing assists in a finger reconstruction operation, the requirement for accurately acquiring individualized ilium block shapes is achieved, when the fetched ilium blocks need to be cut, the fetched ilium blocks can be more rapidly and accurately cut through the navigation module, the operation time is shortened, and harm to a patient is relieved; meanwhile, navigation holes are added in the edge of module, the navigation module is fixed to an ilium region through a kirschner wire during the operation, the displacement phenomenon is avoided, and the length of the finally-obtained ilium blocks is further guaranteed.

Description

technical field [0001] The invention relates to the technical field of an iliac bone block navigation module for finger reconstruction related areas, in particular to a navigation module for taking an ilium bone block in finger reconstruction surgery and a preparation method thereof. Background technique [0002] As the most common surgical disease in clinical practice, hand trauma can cause trauma and loss of fingers in patients. Some patients can undergo finger replantation and reconstruction in emergency surgery, but for some patients, the indications for finger retention in emergency surgery are not available or postoperative Cases of finger necrosis and associated loss of fingers occur, and in these cases patients often require finger reconstruction. [0003] In finger reconstruction, in order to obtain a shape and function closer to a normal finger, it is often necessary to splice and assemble tissue flaps and bone flaps. Among them, the removal of iliac bone blocks is...
