Description
Technical field
The present invention relates to medical instruments fields, and in particular to be a kind of CTA body surface marking auxiliary device and its user
Method.
Background technique
With the application of microsurgical technique improved with various reconstruction technologies, free (flesh) flap of vascularization is moved
Plant, which gradually becomes, repairs the most common mode of oral and maxillofacial surgery incidence soft tissue defects.Since anterolateral thigh (flesh) flap relatively passes
Free (flesh) flap of uniting has many advantages, such as that blood supply is reliable, tissue mass is big, has become soft group of reconstruction oral and maxillofacial surgery incidence
It is optimal for one of valve to knit defect.However, human body anterolateral thigh area perforating branches vessel position and traveling are commonly present individual difference, therefore
Preoperative accurate positioning perforating branches blood vessel is one of the successful key factor of perforating branches (flesh) skin flap transplantation prosthetic.
The method of positioning perforating branches blood vessel is more at present, but not yet forms unified effective method both at home and abroad.Color Doppler
Ultrasonic examination (colordopplerultrasoundscan, CDS) be at present clinically positioning the common method of perforating branches blood vessel it
One, but its Shortcomings on perforating branches blood vessel of the three-dimensional imaging and display diameter of perforating branches blood vessel less than 5mm.Digital Subtraction blood vessel
Radiography (Digitalsubtractionangiography, DSA) is though perforating branches blood vessel can be accurately positioned, and time-consuming for it, and to invade
The operation of entering property has been rarely applied to the positioning of perforating branches blood vessel.Computed tomography blood vessel is made for the first time from Masia in 2006 etc.
Shadow art (Computed tomographyangiography, CTA) be applied to preoperative perforating branches blood vessel positioning since, CTA because its
Accuracy rate is high when preoperative positioning perforating branches blood vessel, can shorten that take the advantages such as valve and operating time constantly to have been reported for perforating branches blood vessel fixed
Position.
CTA is widely used in preoperative positioning perforating branches blood vessel to instruct producing for artery perforator flap and repairing for defective tissue at present
It is multiple to rebuild, but how accurately in patient body-surface corresponding site after finding suitable perforating branches blood vessel by CTA and three-dimensional reconstruction
The position for marking perforating branches blood vessel exit points is still to annoying clinician's a great problem.
In conclusion how effectively by CTA Scan orientation to perforating branches blood vessel be transferred to patient from iconography picture
It is a clinical problem urgently to be resolved that body surface, which be accurately positioned,.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of CTA body surface marking auxiliary device, CTA can effectively be assisted
Perforating branches blood vessel is positioned, macroscopic mark point can be left in patient body-surface corresponding position while CT scan develops, the mark
Note point can significantly improve the quiet true property that CTA result is transferred to patient body-surface.
To achieve the above object, The technical solution adopted by the invention is as follows:
The groove of shell lower end surface is arranged in a kind of CTA body surface marking auxiliary device, the shell including plastic material, if
The developing body that in groove and end face is concordant with shell lower end surface, and setting are set in shell lower end surface and for inciting somebody to action when using
Shell is attached to the attachment band of human skin surface；It is coloured when the end face of the developing body is provided with use in human skin surface
Coloring face.
Further, the shell is provided in upper surface fetches handle convenient for what is taken.
Preferably, the developing body in Warm gutta percha injection groove by solidifying.
Preferably, the attachment band is medical dual-side glue.
Preferably, the coloring face is methylenum careuleum coating.
Based on foregoing teachings, the present invention also provides the application methods of the CTA body surface marking auxiliary device, including walk as follows
It is rapid:
S1, a CTA body surface marking auxiliary device is disposed respectively in body surface region two sides to be checked；
S2, body surface region to be checked is scanned using CTA, and carries out three-dimensional reconstruction processing, obtain each plane and 3-D graphic；
S3, the perforating branches blood vessel in conjunction with selected by each plane and 3-D graphic positioning, in 3-D graphic selected by measurement
Line segment L composed by the developing body of the CTA body surface marking auxiliary device of perforating branches blood exit points and any side1Length x, simultaneously
Measure line segment L1Line segment L composed by developing body with two CTA body surface marking auxiliary devices2Angle, θ；
S4, two CTA body surface markings are determined in the coloured marking that body surface leaves according to two CTA body surface marking auxiliary devices
The line segment L that auxiliary device is formed in the position of body surface, two CTA body surface marking auxiliary devices in the position of body surface3, according to line segment
L3, length x and angle, θ determine selected perforating branches blood vessel exit points in the position of body surface.
Compared with prior art, the invention has the following advantages:
(1) of the invention, production is simple, easy to use；
(2) it is moulded into due to developing body for Warm gutta percha, therefore it can develop in CT scan and effectively evade conventional metals body
Artifact problem existing for list notation object；
(3) production cost of the present invention is low and may be reused, and not will increase the expense of patient's row CTA inspection；
(4) due to having coloring face in developing body end face, therefore it can correspond to position in patient body-surface while CT scan develops
It sets and leaves macroscopic mark point, have during perforating branches vessel position is transferred to patient body-surface from iconography image
It plays an important role, CTA can effectively be assisted to position perforating branches blood vessel.
