Definitions

  • the present invention relates to the education industry. In particular, it relates to training in surgical technique and a perfusion system for conditioning cadaveric specimens for surgical training models.
  • Flap surgery and microsurgery are complex and demanding disciplines in the field of medicine, requiring precise skills and practical experience. These techniques are used to reconstruct damaged or lost tissue, which can be essential for patient recovery after serious injuries or surgical interventions. The precision and skill acquired in these techniques are vital not only to the success of surgical procedures but also to the patient's postoperative quality of life.
  • Advanced flap and microsurgical techniques are fundamental in post-traumatic and post-surgical reconstruction, directly impacting patients' quality of life. The ability to perform these techniques accurately reduces the risk of complications, improves aesthetic and functional outcomes, and accelerates patient recovery.
  • Document CN113793545A describes an operation simulation device and an operational training system.
  • This device includes a first and a second functional platform, as well as an installation platform.
  • the first functional platform consists of a housing assembly, a perfusion assembly, a control module, and a multifunctional connector.
  • the housing has two layers, with the inner layer forming a cavity for storing fluids.
  • the infusion set and control module which are located between the two layers of the housing, communicate with this cavity.
  • the multifunctional connector is located in the housing.
  • the second functional platform which is placed on top of the housing, has a third housing that mimics the shape of the human body, forming an operational cavity.
  • the installation platform removably arranged on the housing, serves to secure tissues and organs.
  • CN113793545A although it provides an operative training system, is not specialized in upper limb simulation, which reduces its effectiveness in specific training such as flap surgery.
  • Document CN114373347A describes a highly simulated, intelligent training system for whole-organ surgery.
  • This system includes multiple modules: a simulation training module, a control module, a body fluid circulation module, an intelligent monitoring and adjustment system, a cooling system, a voice recognition and video recording system, a touch screen module, a lifting system, a data evaluation system, and a power supply module. All of these modules are electrically interconnected with the control module.
  • the system provides a simulation training modality for endoscopic surgery and develops various thoracoscopic surgeries by implementing intelligent control components.
  • Document CN208218830U describes an automatic perfusion device that includes two bottles, a syringe needle, connecting tubing, two peristaltic pumps, a controller, a display screen, and an input keypad.
  • the fluid inlet ports of the peristaltic pumps are connected to the bottles via emulsion tubing, and their outlets are connected to the syringe needle via connecting tubing.
  • the input keypad is used to configure system control, including adjusting the flow time and rate of two types of liquids, and is connected to the controller, which is also linked to the display screen.
  • This configuration eliminates the need to manually change liquids and allows for real-time display of the fluid flow rate and remaining experimental period, as well as adjustments during the experiment.
  • the device also features additional functions such as schematic memory, flow modification, liquid switching, and emulsion tubing cleaning.
  • CN208218830U despite its focus on automated perfusion, does not specialize in upper limb simulation and conditioning for flap surgeries and similar procedures.
  • Document US20170076635A1 describes a training system for vascular procedures that includes a simulator designed to replicate a portion of a human limb, such as a leg.
  • This simulator consists of one or more replicated bones, a plurality of arteries connected to these bones, including at least one obstruction, and a flesh-like substance formed over the bones and arteries, in the shape of the replicated human limb.
  • a fluid pump is connected to at least one of the arteries and is configured to pump a fluid through the plurality of arteries.
  • US20170076635A1 designed to replicate a human limb with a focus on vascular procedures, does not provide a suitable system for conditioning cadaveric limbs for detailed and realistic training in specific upper limb techniques, such as microsurgery or hand reconstructive surgery.
  • Prior art documents present solutions in the field of surgical simulation and training; however, they show significant limitations in their applicability to upper-limb training, such as flap surgery. Overall, these prior art solutions do not meet the specific need for training in upper-limb surgical techniques using properly conditioned cadaveric models.
  • Validation of the model's appearance and content by independent experts was equally positive.
  • the experts evaluated the model through a validation survey, assigning high scores in all aspects assessed. Specifically, they highlighted the model's ability to enable accurate identification of key structures such as the main artery, perforating vessels, and nerves in a surgical setting similar to that of a real surgery. Furthermore, the experts emphasized that the model's perfusion facilitated the identification of technical errors compared to non-perfused cadaveric models, suggesting a substantial improvement in the quality of surgical training provided by this innovative model.
