Biological models for training surgery
techniques and simulation with high precision.

Healtth aims to offer a biological kit  to be used as a high fidelity model for human tissue and organs. The product is sterile and gamma-irradiated with high conservation status. This product can be used as a pack anywhere without contamination. It is odor less and is ready to use.
Research

The conception of Healtth products was based in academic research studies published and reviewed by important medical journals.

Human Placenta Aneurysm Model for Training Neurosurgeons in Vascular Microsurgery
OBJECTIVE: To describe a human placenta model for the creation and clipping of aneurysms.
METHODS: Placental vessels from 40 human placentas that were dimensionally com- parable to the sizes of appropriate cerebral vessels were isolated to create aneurysms of different shapes. The placentas were then prepared for vascular microsurgery exercises. Sylvian fissure–like dissection technique and clipping of large- and small-necked aneurysms were practiced on human placentas with and without pulsatile flow. A surgical field designed to resemble a real craniotomy was reproduced in the model.

Carotid Endarterectomy Surgical Simulation Model Using a Bovine Placenta Vessel

OBJECTIVE: To describe a new haptic CEA model.

METHODS: Six bovine placentas were used to create the model. Each placenta pro- vided about 6 large arterial and venous bifurcations. In total, 36 large-vessel bifurcations were dissected and prepared for the CEA simulation. Bovine placenta vessels were arranged to simulate the common carotid artery (CCA), internal carotid artery (ICA), and external carotid artery (ECA). The diameters and wall thicknesses were measured and compared with human CCA, ICA, and ECA parameters.

Face, Content, and Construct Validity of Brain Tumor Microsurgery Simulation Using a Human Placenta Model

OBJECTIVE: To describe and assess an ex vivo placental model for brain tumor microsurgery using a simulation tool in neurosurgical psychomotor teaching and assessment.

METHODS: Sixteen human placentas were used in this research project. Intravascular blood remnants were removed by continuous saline solution irrigation of the 2 pla- cental arteries and placental vein. Brain tumors were simulated using silicone injections in the placental stroma. Eight neurosurgeons and 8 neurosurgical residents carried out the resection of simulated tumors using the same surgical instruments and bimanual microsurgical techniques used to perform human brain tumor operations. Face and content validity was assessed using a subjective evaluation based on a 5-point Likert scale. Construct validity was assessed by analyzing the surgical performance of the neurosurgeon and resident groups.

Learning brain aneurysm microsurgical skills in a human placenta model: predictive validity

OBJECTIVE: Surgery for brain aneurysms is technically demanding. In recent years, the process to learn the technical skills necessary for these challenging procedures has been affected by a decrease in the number of surgical cases available and progressive restrictions on resident training hours. To overcome these limitations, surgical simulators such as cadaver heads and human placenta models have been developed. However, the effectiveness of these models in improving technical skills is unknown. This study assessed concurrent and predictive validity of brain aneurysm surgery simulation in a human placenta model compared with a “live” human brain cadaveric model.

Face, content, and construct validity of human placenta as a haptic training tool in neurointerventional surgery

OBJECTIVE: The development of neurointerventional treatments of central nervous system disorders has resulted in the need for adequate training environments for novice interventionalists. Virtual simulators offer anatomical definition but lack adequate tactile feedback. Animal models, which provide more lifelike training, require an appropriate infrastructure base. The authors describe a training model for neurointerventional procedures using the human placenta (HP), which affords haptic training with significantly fewer resource requirements, and discuss its validation.

Products

Our products were designed aiming for a better experience during procedures execution because it is possible to use several surgery techniques.

• IDHS Model = Incision, Dissection, Hemostasis and suture simulation

a. Use of the majority of sutures from 0 to 4-0, and cutting and coagulation tissue electric instruments;

b. Reproduction of superficial tumors;

c. Any perfusion pressure can be used.

Tumors models are easily used in laparoscopic surgeries and many instruments can be used.

• Microsurgery, aneurism and vascular/cardiac surgery model = small veins microsurgery

a. Aneurisms to simulate cerebral surgery

b. Veins with diverse diameters to simulate vascular sutures

c. Vein puncture with ultra-sound orientation

d. cardiac bypass surgery – including outsider pump

e. Use of 6-0 to 11-0 sutures, clips, instruments and catheters

Aplications

Surgery simulation technology developed by Healtth can be used in a wide variety procedures:

• Open surgery – superficial and severe trauma

• Laparoscopy/endoscopy – abdominal, scrull base and ventricular

• Microsurgery – plastic and neurosurgery

• Vascular – superficial, cardiac, aorta aneurisms

• Endovascular

The products can also be used by surgery material factories thus dispositives as sutures dissectors, coagulators and other surgery instruments would be accurately tested.

“We believe that doctors, veterinarians, nurses and industries should have access to an innovative form of surgical simulation that is more reliable, close to real and free of ethical issues.”
