Description
Technical field
The utility model relates to a kind of medical educational technical field, specifically a kind of pelvis based on 3D printing technique
Repair Safe screw channel teaching mode.
Background technique
Pelvis is that a complete annular is closed bone ring, for the important feature for connecting trunk and lower limb, will come from body
Dry gravity is transmitted to double lower limb, and the stability of pelvis will affect the standing and walking of human body by destruction, or even can jeopardize life
Life.
In the treatment of injury of pelvis, screw repairs pelvis and needs to have exit passageway one stringent control, in view of people
Body pelvis exit passageway region is hidden in inside pelvis, and the exit passageway of screw reparation can not be only shown by standard teaching mode,
True case is even more that can not demonstrate.
With the fast development of the technologies such as CT, MRI, PET and digitlization medical technology, healthcare givers can be simple and quasi-
The three-dimensional stereo data information for really obtaining organism, with the help of 3D printing technique, 3 D stereo medical model will be by
Rapid build is completed.Constructed medical model can be used for medical educational and surgical simulation, have biggish practical significance.
Utility model content
To solve the above-mentioned problems, the utility model devises a kind of pelvis reparation Safe screw based on 3D printing technique
Channel teaching mode, the postoperative model based on true case, and exit passageway can be successively confirmed by hierarchical model, it imparts knowledge to students
Effect is intuitive, objective, has been applied to hospital's teaching.
The technical solution of the utility model are as follows:
A kind of pelvis reparation Safe screw channel teaching mode based on 3D printing technique, it is characterised in that: including center
Axis, the central axis both ends are installed with the fixed bracket of pelvis respectively, and axis connection has 9 rotation struts on the central axis, described
Rotation strut top is swivel becket, is the body of rod in the middle part of the rotation strut, and the rotation strut bottom is connecting pin, each described
The body of rod is equipped with location hole, and the location hole can integrally run through；Wherein, 3, the left side body of rod length is 6 centimetres, 5 intermediate
The body of rod length is 2 centimetres, and 1, the right side body of rod length is 7.5 centimetres.
Further, the fixed bracket of the pelvis is connected on pelvis, and the connecting pin is connected on bone slice.
Further, the cast material is photosensitive resin.
Utility model has the advantages that the postoperative model based on true case, and can be layer-by-layer by hierarchical model
Confirm exit passageway, teaching efficiency is intuitive, objective, has been applied to hospital's teaching.
The utility model is described in further detail with reference to the accompanying drawings and examples.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Fig. 2 is pelvis bone block part in Fig. 1 institute representation model.
Specific embodiment
The preferred embodiment of the utility model is illustrated below, it should be understood that preferred embodiment described herein
It is only used for describing and explaining the present invention, is not used to limit the utility model.
Embodiment 1
As shown in Fig. 1-2, a kind of pelvis reparation Safe screw channel teaching mode based on 3D printing technique, specific mould
Type includes bone block part and rotation body portion, wherein bone block part is pelvis 5, and pelvis 5 includes ilium 501, ischium 502, pubis
503, which is the pelvis model of true case, obtains CT or MRI data after true surgery first, and carry out Three-dimensional Gravity
It builds, exit passageway is sliced in reconstruction process, show that screw repairs exit passageway by centimetre.
Rotating body portion includes central axis 1, is fixedly installed pelvis fixed frame 2 respectively at the both ends of central axis, pelvis is solid
Determine frame 2 to be fixedly connected on ilium 501, is connected on ilium to play positioning action to central principal axis by pelvis fixed frame
And fixed function, axis connection has 9 rotation struts 3 on central principal axis, and the top of each rotation strut is swivel becket 301, rotation
The middle part of strut is the body of rod 302, and the bottom for rotating strut is connecting pin 303, and each body of rod is equipped with location hole 4, institute on the body of rod
There is location hole that can integrally run through.
Wherein, 3, left side body of rod length is 6 centimetres, and intermediate 5 body of rod length are 2 centimetres, and 1, right side body of rod length is
7.5 centimetre.People adult after, ilium 501, ischium 502, pubis 503 healing be one piece of pelvis entirety, ilium 501, ischium 502,
There is closed pore among pubis 503.Entire bone block lower part is sliced, and bone block is by centimetre being sliced above closed pore, quadrate bone under closed pore
Block portion point is without cm chips.3 rotation struts of central axis upper left side are sliced by the connecting pin and left side bone block of lower part
Connection, body of rod length are 6 centimetres, are specifically connected with ischium slice on the left of closed pore；Intermediate 5 turn on central axis
Dynamic strut is connected by the connecting pin and intermediate bone block slice of lower part, and body of rod length is 2 centimetres, specifically and on closed pore
Square pubis slice and ischium slice are connected；The connecting pin and right side bone that 1 rotation strut on right side passes through lower part on central axis
Block slice connection, body of rod length are 7.5 centimetres, are specifically connected with pubis slice on the right side of closed pore.
Location hole on each rotation branch club shaft can integrally be run through by a thin bar, carry out original bone block to bone block slice
The reset of shape, it is also possible to control the relative position between rotation strut, and when teaching mode is stored to model
Carry out arrangement fixation.Entire model is made of 3D printing technique, and cast material is photosensitive resin.
