Abstract
In recent years there has been a significant increase in ovariohysterectomy (spaying) surgeries on animals in Brazil. To lower the costs and optimize these surgical procedures, an implantable, biocompatible mechanical device was developed using nylon, aiming to replace the surgical wires and staples commonly used in neutering. The project was divided into three phases: the first phase, the development and design of the pieces, based on the uterine anatomy of domestic cats, and the second phase, with simulations for the closure and locking of the device and to seal the hemodynamics of blood vessels and arteries, tested in synthetic materials and anatomical parts of cats (ex vivo), and the third phase where the parts were submitted to different sterilization processes commonly used in healthcare. The nylon device presented an excellent lock composed of two pieces that fit into each other, being able to occlude the organ and generate hemostasis when applied in ex vivo material, besides not changing its form or function when submitted to different sterilization processes. Future steps will include cytotoxicity and in vivo tests with biocompatible resins.
