摘要: A surgical simulator for electrosurgical training and simulation is provided. The surgical simulator includes one or more simulated tissue structures made substantially of a hydrogel comprising a dual interpenetrating network of ionically cross-linked alginate and covalently cross-linked acrylamide. Combinations of different simulated tissue structures define procedural-based models for the practice of various electrosurgical procedures including laparoscopic total mesorectal excision, transanal total mesorectal excision, cholecystectomy and transanal minimally invasive surgery. Methods of making the simulated tissue structures are also provided.

摘要: A polymer substrate, such as a polymer particle, is formed from a carboxyl functional monomer. In an example, the carboxyl functional monomer has a protection group in place of the OH of the carboxyl group. Once the monomer is polymerized, such a protection group can be removed, providing a polymer network with carboxyl functional sites. Such sites can be used to attach other functionality to the polymer substrate.

摘要: A method for making a tough and compliant hydrogel. A precursor hydrogel is made of a first polymer selected to maintain high elasticity and a second polymer selected to dissipate mechanical energy. The precursor hydrogel is stretched to a multiple of its original length to form a pre-stretched hydrogel. The pre-stretched hydrogel is allowed to relax and is soaked in a biocompatible solvent to reach equilibrium swelling of the pre-stretched hydrogel whereby shear modulus of the hydrogel is reduced.

摘要: An alginate-polyacrylamide IPN hydrogel formulation for 3D printing using a dual syringe system where the components that initiate polymerization of each network remain separated until printing. The dual syringe system may use a single motor and mixing head to combine both parts of the hydrogel formulation for controlled polymerization of the material. The elastic and time-dependent viscoelastic properties (stress relaxation) are tuned to match mammalian tissues by changing the crosslink density and monomer concentration. The fracture energy of the material may be increased by soaking in a calcium chloride solution. The resulting IPN polymer material may find application in soft tissue medical simulation devices, particularly because the mechanical properties may be tuned to mimic the elastic and viscoelastic properties of muscle tissue and may be 3D printed in the shape of anatomical parts.
