“…These have been used to simulate laparoscopic surgery, neurosurgery, and oral surgery. [222324] In Thiel cadavers, due to fluid in tissues echogenicity of muscles increases which enhances the sonographic contrast between muscles and nerves. [21] This technique offers high standard of preservation without releasing harmful chemicals in the environment.…”

Ultrasound-guided regional anesthesia (UGRA), like other basic skills, should be learnt in a simulation laboratory before performing on the patient. Cadavers provide an ideal tool for learning sonoanatomy and skills required for performing UGRA. On the basis of preservation technique used, the cadavers can be formalin embalmed cadavers, Thiel cadavers (soft cadavers), and fresh frozen cadavers. We compared three types of cadavers for performing ultrasound-guided upper and lower limb blocks. We observed that fresh frozen and Thiel cadavers were less smelling and had more realistic appearance as compared to formalin embalmed cadavers. It was seen that Thiel cadavers were more flexible and hence, rotation of neck, shoulder and knee was easier. Although images seen in most cadavers were comparable with live subjects but, Thiel cadavers provided more realistic model.

“…The specimens were embalmed in Thiel solution. The Thiel embalming technique results in largely unchanged mechanical properties of bone and soft tissue structures (Bregy et al, 2008;Thiel, 1992;Wolff et al, 2008). Thiel specimens have already been shown to be a reliable model for middle ear research in the development of the DACS at our institution (Hausler et al, 2008).…”

Large open surgical approaches are being extensively replaced by endoscopic and robotic techniques. Yet, these developments have not been paralleled by the necessary improvements in tissue adaptation, fusion or fixation. In order to advance the surgical area to a higher and improved level, adequate tissue fusion methods need to be designed. We therefore developed a sutureless electromagnetic tissue soldering technique, using superparamagnetic iron oxide nanoparticles (SPIONs). A magnetic field in combination with SPIONs as energy transmitters for absorption was used to fuse rabbit aortic tissue in vitro. Temperature profiles and rupture forces of the fused vascular tissue were measured and histological analyses were performed. The rupture force of the fused rabbit aortas was 3078 ± 852 mN. The experiments revealed the feasibility of tissue fusion by electromagnetic heating of SPIONs, which proved to be a novel promising tissue soldering technique.
