In concrete implementation mode, firstly, the cutting procedure of wound window is described in detail.Fig. 3 is to show according to the present invention
The illustrative diagram of wound window in the computer assisted heel string brace manufacturing method of embodiment two, referring to Fig. 3, it is postoperative every
Several days doctors will change a medicine, 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.
Move dislocation and the change of elasticity in view of dressing process will will lead to brace, thus, wound location in the three-dimensional model into
Row windowing, i.e., after getting brace threedimensional model, using Color images detecting wound location, and with wound line, (its length is made
For the length of rectangle) be two broadside midpoints of rectangle connecting line, building width be 4~6cm wound window rectangular area, and
Wound window region is partitioned into threedimensional model.Directly wound window directly can be unloaded when dressing, rather than open entire brace, this
Sample not only reduces patient pain, but also avoids dismounting brace process, is convenient for doctor's dressing.It should be noted that Fig. 3 only shows
Illustrate wound window to example property, not as the restriction of the design parameters such as position, size to wound window.
Secondly, the labeling process of long leg brace and short leg brace cut-off rule is described in detail.After usual heel string operation, first have to
Long leg brace is worn, wears short leg brace after two weeks.In order to enable heel string brace has versatility, can be done on long leg brace
The brace of short-leg part can be obtained that is, along segmentation wire cutting in a cut-off rule.For example, Fig. 4 is to show according to the present invention
The illustrative diagram of long leg brace and short leg brace, reference in the computer assisted heel string brace manufacturing method of embodiment two
Fig. 4 can make a groove, at mark line using the place of 6cm below the knee of limbs of patient model as mark line in order to rear
Long leg brace is become short leg brace by the phase.It should be noted that Fig. 4 is only illustratively to illustrate long leg brace and short leg brace
Cut-off rule, not as the restriction of the specific location to cut-off rule.
Finally, ventilation hole is described in detail.In view of heel string brace wear time is long, cutaneous necrosis in order to prevent, this
In embodiment, by designing ventilation hole on brace surface, to keep limbs and extraneous ventilation.For example, Fig. 6 is shown according to this
The illustrative diagram of ventilation hole in the computer assisted heel string brace manufacturing method of inventive embodiments two, in limbs of patient mould
The ventilation hole designed in type is as shown in fig. 6, design the cavity that a diameter is 0.5cm every 2cm.It should be noted that Fig. 6 is only
It is the design for illustratively illustrating ventilation hole, not as the restriction of the design parameters such as position, size of arranging to ventilation hole.
In step S250, control the three-dimensional upper brace model of 3D printing equipment printing and three-dimensional lower brace model, produce with
