At the forefront of medicine and technology, we are proud to offer these incredible, uncompromised replicas of human anatomy. Using the latest 3D printing technology and materials available, this model is an exact replica of a human cadaver, brought to "life" by extensive medical scanning and manufacturing technologies. Over are the days of using ethically questionable cadavers, the mess of hazardous preservation chemicals, and the inaccuracies of plastinated models that often over-enhance anatomy for display, not realism. See the future, and the beauty, of real human anatomy with these incredible anatomical replicas!
This large, multipart 3D printed specimen displays the entire male posterior abdominal wall from the diaphragm to the pelvic brim, as well as pelvic anatomy and to the proximal thigh. This same individual specimen is also available as a pelvic and proximal thigh specimen (MP 1770).
The parietal peritoneum has been removed from the posterior abdominal wall to expose the muscular wall including the psoas, the quadratus lumborum, transversus abdominus, and the iliacus below the iliac crest. The muscular portions of the dome shaped diaphragm are clearly distinct from the central tendon. The fibres originate from the circumference of the internal walls of the bony thorax at its margin (sternal fibres, costal portion, lumbar portion). The origins of the diaphragm and the left and right crura are clearly identifiable originating from the vertebral bodies (L1-L3 on the right and L1-L2 on the left. The crura are connected by a tendinous band, the median arcuate ligament, which arches in front of the aorta; however in this specimen the aorta has been removed. The fibres of the diaphragm arising from the tendinous arches over psoas and the lateral arcuate ligaments are partly hidden by the kidneys. The oesophageal opening through the arching fibres of the right crus is present above (level of T10) and to the left of the aortic opening (level of T12). The opening in the central tendon that transmits the inferior vena cava (level of T8/9 intervertebral disc).
The somatic nerves of the posterior abdominal wall are clearly identifiable and consist of from above downwards - the subcostal, the iliohypogastric and ilioinguinal nerves lie on the quadratus lumborum (in this individual they arise together and- this can often occur and they split later in abdominal muscle layers), the lateral cutaneous nerve of thigh, the femoral lying in the groove between psoas and iliacus), and the genitofemoral nerve lying superficially upon psoas. The sympathetic trunks can be seen descending lateral to the lumbar vertebral bodies.
The aorta and inferior cava are transected around the level of L3 vertebral body. The aortic bifurcation into the right and left common iliac arteries is slightly higher than normal.
Finally, the kidneys have dissected from the peri- and pararenal fat of the posterior abdominal wall. The renal vessels (arteries anteriorly, veins posteriorly) have been preserved but as the aorta and inferior cava have been removed this does display the origin and arrangements of these vessels fully. The more inferior position of the right kidney is clearly visible and the ureters can be seen emerging from the hilum and descending initially lateral to psoas, then anterior to this muscle before crossing pelvic brim anterior to the bifurcation of the common iliac arteries to reach the true pelvis.
Please Note: Thanks to the flexibility of manufacturing that 3D Printing offers, this model is "printed to order", and is not typically available for immediate shipment. Most models are printed within 15 working days and arrive within 3-5 weeks of ordering, and once an order is submitted to us, it cannot be canceled or altered. Please contact us if you have specific a specific delivery date requirement, and we will do our best to deliver the model by your target date.
Advantages of 3D Printed Anatomical Models
- 3D printed anatomical models are the most anatomically accurate examples of human anatomy because they are based on real human specimens.
- Avoid the ethical complications and complex handling, storage, and documentation requirements with 3D printed models when compared to human cadaveric specimens.
- 3D printed anatomy models are far less expensive than real human cadaveric specimens.
- Reproducibility and consistency allow for standardization of education and faster availability of models when you need them.
- Customization options are available for specific applications or educational needs. Enlargement, highlighting of specific anatomical structures, cutaway views, and more are just some of the customizations available.
Disadvantages of Human Cadavers
- Access to cadavers can be problematic and ethical complications are hard to avoid. Many countries cannot access cadavers for cultural and religious reasons.
- Human cadavers are costly to procure and require expensive storage facilities and dedicated staff to maintain them. Maintenance of the facility alone is costly.
- The cost to develop a cadaver lab or plastination technique is extremely high. Those funds could purchase hundreds of easy to handle, realistic 3D printed anatomical replicas.
- Wet specimens cannot be used in uncertified labs. Certification is expensive and time-consuming.
- Exposure to preservation fluids and chemicals is known to cause long-term health problems for lab workers and students. 3D printed anatomical replicas are safe to handle without any special equipment.
- Lack of reuse and reproducibility. If a dissection mistake is made, a new specimen has to be used and students have to start all over again.
Disadvantages of Plastinated Specimens
- Like real human cadaveric specimens, plastinated models are extremely expensive.
- Plastinated specimens still require real human samples and pose the same ethical issues as real human cadavers.
- The plastination process is extensive and takes months or longer to complete. 3D printed human anatomical models are available in a fraction of the time.
- Plastinated models, like human cadavers, are one of a kind and can only showcase one presentation of human anatomy.
Advanced 3D Printing Techniques for Superior Results
- Vibrant color offering with 10 million colors
- UV-curable inkjet printing
- High quality 3D printing that can create products that are delicate, extremely precise, and incredibly realistic
- To improve durability of fragile, thin, and delicate arteries, veins or vessels, a clear support material is printed in key areas. This makes the models robust so they can be handled by students easily.
