Example Embodiment

[0030] Example 1:

[0031] A navigation module for fetching iliac bone in a finger reconstruction operation includes a navigation module 1. There are 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 for iliac bone block removal during finger reconstruction surgery, the specific steps are:

[0033] The first step is to collect CT data from 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 virtual two-hand three-dimensional model obtained by the three-dimensional reconstruction into a three-dimensional printer, and print out the two-hand physical model;

[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 missing fin...

Example Embodiment

[0047] Example 2:

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

[0049] In this way, the present invention can be better fixed to prevent falling off or deviation.

[0050] The purpose of the present invention is to provide a navigation module for iliac bone extraction in finger reconstruction surgery and a preparation method thereof. When the iliac bone block needs to be cut, the navigation module 1 can cut the iliac bone block faster and more accurately. The shape of the iliac bone block that meets the requirements of reconstruction is formed, which reduces the operation time and reduces 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...
