Technical field
This utility model relates to a kind of CT of ear image guide, relates in particular to the fixing CT of the ear image guide of a kind of energy.
Background technology
The three-dimensional orientation analysis that before implant operation, application of radiation template and CT technology are intended implantation region Coronal, sagittal plain, axle position and any fault trend bone to implantation body of auricular defect district is one of successful key link of implant operation reparation.
After patient's ear disappearance, disappearance side adjacent tissue lacks anatomical structure that can supplementary retention, therefore to obtain stable maintenance more difficult for the CT of ear template, when row CT scan, be easily subjected to displacement, make the position of gauge point occur deviation compared with intending plantation site on CT image, mislead clinician to intending the A+E of growing area osseous tissue situation, and then cause the generation of complication in serious art.Therefore, the maintenance problem of the solution CT of ear template is very important.There is reported in literature to utilize lower jaw natural dentistry to be connected with ear CT image guide as maintenance part abroad, play supplementary retention effect.
The problem that existing ear image guide exists: 1. manufacturing process is more loaded down with trivial details, need to produce respectively the model of ear defective region and lower jaw natural dentistry, then both are coupled together; 2. may cause the displacement of ear's CT template in manufacturing process, mislead clinician, cause complication in serious art.
Utility model content
The defects such as the existing CT of ear image guide making is loaded down with trivial details in order to overcome, maintenance is poor, easy generation displacement, the CT of the ear template that this utility model obtains utilizes finished product earphone frame as supplementary retention device innovatively, has well solved above problem.
A kind of CT of ear image guide, comprise: headset main body, earphone frame, CT image guide and earphone head, described earphone head is arranged on the both sides of headset main body, one end of described earphone head is provided with rubber earplug, the tip filling of described rubber earplug is useful on the gutta-percha of the strong side external auditory meatus mid point of labelling, the described earphone head other end is provided with CT image guide, on described CT image guide, is marked with and intends plantation site and external auditory meatus mid point with gutta percha point.
This utility model adopts above technical scheme, its advantage is, telescopic earphone frame: earphone frame adjustable and retractable, can meet Different Individual and in the time wearing, keep stable, make ear's CT template there is versatility, especially in the time carrying out ear's host site anatomical research and need great amount of samples, be not required to be each volunteer and make personalized CT template, greatly reduce making intensity.
External auditory meatus location earplug: at strong side head, one rubber earplug is installed, most advanced and sophisticated filling gutta-percha carrys out the strong side external auditory meatus mid point of labelling.
CT image guide: material is plastic tab is applied vacuum film pressing machine and thermoplastic sheet and is made CT image guide in patient's auricular defect district template, and intends plantation site and external auditory meatus mid point with gutta percha point labelling in template.
Preferably, described earphone frame adjustable and retractable.
Preferably, the material that described CT image guide adopts is plastics.
Preferably, in described earphone head, rubber earplug is installed, the tip of described rubber earplug arranges porose, carrys out the strong side external auditory meatus mid point of labelling for clogging gutta-percha.
Preferably, the diameter in described hole is 2mm.
Preferably, described head center part is provided with a circular hole, is inserted with the sticking plaster matching with described external auditory meatus central point in described circular hole.
Preferably, on described CT image guide, intend plantation site and external auditory meatus mid point with gutta percha point labelling.
The beneficial effects of the utility model are:
1. efficiently solve the maintenance problem of the CT of ear image guide; Earphone frame obtains easily, has removed manufacturing process from; Choose the frame of plastic material, not metal-containing material, does not produce any impact to CT image.
2. earphone frame adjustable and retractable, can meet Different Individual and in the time wearing, keep stable, make ear's CT template there is versatility, especially in the time carrying out ear's host site anatomical research and need great amount of samples, be not required to be each volunteer and make personalized CT template, greatly reduce making intensity.
3. earphone frame also makes both sides keep interlock, can utilize the repeatability of strong side head position, and the homogeneity of the auxiliary position of determining Ipsilateral template also plays the effect of part maintenance simultaneously.
4. utilized patient's auricular defect side to intend the surperficial sunk structure of planting area, the tissue surface of the CT template that application of air compression molding techniques is made matches with the depression of intending growing area, can play auxiliary template maintenance.And while wearing template, as long as ensure that the definite external auditory meatus mid point of skin surface is consistent with the external auditory meatus mid point holding position of labelling in template, just can in the time wearing, ensure the repeatability of CT template position.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of embodiment of this utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferably embodiment of the present utility model is described in further detail:
As shown in Figure 1, this utility model is mainly made up of following part:
1-earphone frame, 2-external auditory meatus location earplug, 3-CT image guide.
embodiment 1
(1) produce auricular defect section model: first on the skin of patient's auricular defect side, determine and labelling plan plantation site and external auditory meatus mid point, then applying silicon caoutchouc elasticity modeling composition is obtained auricular defect district die, after silicone rubber hardening, the gauge point being marked on skin is transferred to stamp surfaces.Adopt embankment method perfusion plaster model, after its hardening, repair and the gauge point of stamp surfaces is transferred to plaster model surface and marked.
