The corresponding wound window region of wound location of limbs of patient, and/or, mark for brace model in three-dimensional and three-dimensional lower brace
Model carries out the line of demarcation of length segmentation, and/or, the air vent of predetermined number is set.
In concrete implementation mode, first, the cutting procedure of wound window is described in detail.Fig. 3 is shown according to the present invention
The illustrative diagram of wound window in the computer assisted heel string brace manufacture method of embodiment two, reference picture 3, it is postoperative every
Doctor will change a medicine within several days, need to unload brace before dressing, again wear brace after dressing.And early postoperation patient's leg
After type tentatively adapts to brace shape, if brace moves dislocation or brace elasticity is different, pain and sense of discomfort will be brought to patient.
Brace will be caused to move dislocation and the change of elasticity in view of dressing process, thus, wound location in the three-dimensional model is entered
Row windowing, i.e., after brace threedimensional model is got, using Color images detecting wound location, and (its length is made with wound line
It is the length of rectangle) it is two connecting lines at broadside midpoint of rectangle, structure width is the wound window rectangular area of 4~6cm, and
Wound window region is partitioned into threedimensional model.Directly wound window directly can be unloaded during dressing, rather than the whole brace of opening, this
Sample not only reduces patient pain, and avoids dismounting brace process, is easy to doctor's dressing.It should be noted that Fig. 3 only shows
Wound window is illustrated on example property ground, not as the restriction of the design parameters such as the position to wound window, size.
Secondly, the labeling process of long leg brace and short leg brace cut-off rule is described in detail.Usual heel string Post operation, first has to
Long leg brace is worn, short leg brace is worn after two weeks.In order that obtaining heel string brace has versatility, can be done on long leg brace
Individual cut-off rule, i.e., along segmentation wire cutting, you can obtain the brace of short-leg part.For example, Fig. 4 is shown according to the present invention
The illustrative diagram of long leg brace and short leg brace, reference in the computer assisted heel string brace manufacture method of embodiment two
Fig. 4, can make a groove, in order to rear using the place of the knee of limbs of patient model lower section 6cm as mark line at mark line
Long leg brace is changed into short leg brace by the phase.It should be noted that Fig. 4 is only exemplarily to illustrate long leg brace and short leg brace
Cut-off rule, not as the restriction of the particular location to cut-off rule.
Finally, air vent is described in detail.It is long in view of heel string brace wear time, in order to prevent cutaneous necrosis, this
In embodiment, the ventilation of limbs and the external world is kept by designing air vent on brace surface.For example, Fig. 6 is shown according to this
The illustrative diagram of air vent in the computer assisted heel string brace manufacture method of inventive embodiments two, in limbs of patient mould
The air vent designed in type every 2cm as shown in fig. 6, design a cavity of a diameter of 0.5cm.It should be noted that Fig. 6 is only
It is exemplarily to illustrate the design of air vent, not as the restriction of the design parameters such as arrangement position, the size to air vent.
In step S250, the three-dimensional upper brace model of control 3D printing equipment printing and three-dimensional lower brace model, produce with
Tendon brace.
Wherein, content is identical the step of step S150 with above-described embodiment one for the step of above-mentioned steps S250 contents,
This is repeated no more.
In step S260, using threedimensional model, brace model and three-dimensional lower brace model, empty on computers in three-dimensional
Plan is worn, dressing and rehabilitation training, also, in the data of the threedimensional model of generation STL forms, three-dimensional brace model number
According to the data of brace model under three-dimensional and Rehabilitation planning documentation, virtual rehabilitation demonstration document.
Because Most patients are known nothing method of rehabilitation and details, current many orthopedists only pay attention to operation, right
The rehabilitation attention degree in later stage not enough, lacks and instructs, and then causes the patient can only to be asked for help by network.But different patients
Rehabilitation course vary with each individual, thus seem very helpless in patient's rehabilitation course after surgery, it is not known that how to carry out rehabilitation instruction
Practice, and then cause that recovery training method is proper, recovery period is long, great pain is brought to patient.
Postoperative rehabilitation and operation no less important for heel string.There is a comprehensively understanding to rehabilitation course to allow patient,
Increase the confidence of Rehabilitation, after the upper and lower brace support threedimensional model after receiving limbs model and treatment, doctor is in computer
Under the auxiliary of technical staff, according to patient body situation, on computers virtual three-dimensional brace wear, dressing and rehabilitation
Journey, simulates the rehabilitation training methods that brace wears process and different phase, and then formulate rehabilitation by computer 3D technology
Plan, output STL mathematical models, Rehabilitation planning documentation and virtual rehabilitation demonstration document.Visualize the number of rehabilitation efficacy
Word model directly can on computers carry out rotation observation, the observation of arbitrary tangent and the zoom in each orientation, lead to
The three-dimensional visualization of rehabilitation course and result is crossed, doctor patient communication is facilitated, allows patient more clearly to experience rehabilitation course, in advance
The mental preparation of abundance is carried out, Rehabilitation confidence is established, satisfaction of the patient to understanding and the treatment of rehabilitation course is considerably increased.
In step S270, in one or more in storage data below to limbs of patient database：Three dimensional point cloud,
Brace model, three-dimensional descend data, three of brace model in brace model, the data of threedimensional model, three-dimensional in threedimensional model, three-dimensional
The data of brace model, Rehabilitation planning documentation and virtual rehabilitation demonstration document under dimension.
In concrete implementation mode, using structured system analysis with the method for designing for patient sets up limbs of patient
Database, the limbs of patient database equivalent to a rehabilitation data management system, wherein the patient that is stored with, doctor and designer
Essential information, and in operation and rehabilitation course data (including as the preoperative collection of patient data, the three-dimensional mould of limbs
Type, upper and lower brace model and patient's therapy rehabilitation plan relevant documentation etc.).The convenient follow-up letter of the foundation of limbs of patient database
The inquiry of breath, edit and call, improve the operating efficiency of patient information management.
