Description
Technical Field
The invention relates to the field of medical instruments, in particular to a CTA body surface marking auxiliary device and a using method thereof.
Background
With the perfection of microsurgery and the application of various repair and reconstruction techniques, vascularized free (muscle) flap implantation has become the most common way to repair soft tissue defects of the oromaxillofacial head and neck. As the anterior and lateral (muscle) skin flap has the advantages of reliable blood supply, large tissue quantity and the like compared with the traditional free (muscle) skin flap, the skin flap becomes one of the most ideal supply flaps for repairing and reconstructing the soft tissue defects of the head and neck of the oral jaw face. However, there are often individual differences in the position and the running of the branch vessels in the anterolateral region of the human thigh, so that accurate positioning of the branch vessels before operation is one of the key factors for success of the branch (muscle) skin flap graft repair.
At present, a plurality of methods for positioning the through branch blood vessels are available, but no unified and effective method is formed at home and abroad. Color doppler ultrasound (color dopplerultrasound scan, CDS) is one of the methods currently in common use for locating a perforator blood vessel clinically, but it has shortcomings in stereoscopic imaging and displaying of perforator blood vessels with diameters less than 5 mm. Digital subtraction angiography (Digital subtraction angiography, DSA), while accurately locating a perforator, is time consuming and is an invasive procedure, it is rarely used for perforator localization. Since Masia et al first applied computed tomography angiography (Computed tomography angiography, CTA) to pre-operative positioning of a perforator vessel, CTA has been reported to be used for positioning a perforator vessel due to its advantages of high accuracy in pre-operative positioning of a perforator vessel, shortened valve removal and operation time, etc.
At present, CTA is widely used for preoperatively positioning a through-branch blood vessel so as to guide preparation of a through-branch skin flap and repair and reconstruction of defective tissues, but how to accurately mark the position of a through-branch blood vessel passing-out point at the corresponding position of the body surface of a patient after finding out a proper through-branch blood vessel through CTA and three-dimensional reconstruction still has a great difficulty for clinicians.
In summary, how to effectively transfer the debranched blood vessel located by CTA scanning from the imaging picture to the body surface of the patient for accurate location is a clinical problem to be solved urgently.

In order to achieve the above purpose, the technical scheme adopted by the invention is as follows:
A CTA body surface marking auxiliary device comprises a shell made of plastic, a groove arranged on the lower end surface of the shell, a developing body arranged in the groove and with the end surface being level with the lower end surface of the shell, and an attaching ring arranged on the lower end surface of the shell and used for attaching the shell to the skin surface of a human body in use; the end face of the developing body is provided with a coloring surface which is colored on the surface of human skin when in use.
Further, the shell is provided with a handle convenient to take on the upper end face.
Preferably, the developing body is formed by injecting hot gutta-percha into the groove to be solidified.
Preferably, the attachment ring is a medical double sided tape.
Preferably, the coloured surface is a methylene blue coating.
Based on the foregoing, the invention also provides a method for using the CTA body surface marker assisting device, which comprises the following steps:
s1, respectively arranging a CTA body surface marking auxiliary device at two sides of a body surface to-be-inspected area;
S2, scanning a region to be inspected of the body surface by using CTA, and performing three-dimensional reconstruction processing to obtain each plane and a three-dimensional graph;
S3, positioning the selected through branch blood vessel by combining each plane and the three-dimensional graph, measuring the length x of a line segment L 1 formed by the selected through branch blood vessel penetrating point and the developing body of the CTA body surface marking auxiliary device at any side on the three-dimensional graph, and simultaneously measuring the angle theta of a line segment L 1 and a line segment L 2 formed by the developing bodies of the two CTA body surface marking auxiliary devices;
S4, determining the positions of the two CTA body surface marker auxiliary devices on the body surface according to the coloring marks left by the two CTA body surface marker auxiliary devices on the body surface, determining the positions of the selected penetrating and supporting blood vessel penetrating points on the body surface according to a line segment L 3 formed by the positions of the two CTA body surface marker auxiliary devices on the body surface and the line segment L 3, the length x and the angle theta.
Compared with the prior art, the invention has the following beneficial effects:
(1) The invention has simple manufacture and convenient use;
(2) Because the developing body is formed by hot gutta-percha, the developing body can develop in CT scanning and effectively avoids the artifact problem of the traditional metal body surface marker;
(3) The invention has low production cost and can be reused, and does not increase the cost of CTA examination of patients;
(4) The end face of the developing body is provided with the coloring surface, so that macroscopic marking points can be left at the corresponding position of the body surface of the patient during CT scanning and developing, the method plays an important role in the process of transferring the position of the through branch blood vessel from an imaging image to the body surface of the patient, and can effectively assist CTA to position the through branch blood vessel.
