Definitions

  • the present invention relates to a device for training multiple haptic skills in laparoscopy, based on a progressive and hierarchical method for acquiring motor skills Necessary for proficiency in the laparoscopic technique.
  • the device consists of a rigid ABS base, which serves to support a hexagonal-shaped silicone plate, which has several regions where the following skills are developed through exercises: ergonomics, notions of three-dimensionality and depth, touch, force control, basic motor coordination, fine motor coordination, integrated hand coordination, scissor coordination, traction and counter-traction, exposure and assistance between the clamps, ability to rotate the tip of the clamps; needle manipulation and positioning; wire and knot manipulation; and endosuture;
  • the equipment must be used according to the recommended method, which is hierarchical and composed of 6 progressive layers of complexity.
  • the rigid ABS base has on its rear face a region with velcro to be attached to the interior of the mechanical bench simulator (“black box”), to provide stability, preventing it from moving during the execution of the exercises; the device has an anterior angle, in order to improve the presentation of the operated surfaces.
  • the device has at its lower end a region that allows to store the objects used in training (dumbbells); as well as an upper slot that allows to store the EVA plates, which will be cut and discarded, being the only consumable item of the present invention.
  • Models for training skills in laparoscopy are already known for use in benchtop surgical simulators, which have individual models for training specific skills, which in general does not allow the systematization of learning in the technique. Dwarf- systematization in learning the technique hastily accelerates the performance of more complex tasks (such as laparoscopic suture), while the basic skills have not yet been acquired, which causes numerous deleterious effects on the skills of a surgeon in training, as it allows deterioration in art of technique.
  • the training model consists of two units, a rigid ABS base and a silicone plate.
  • the silicone plate has a density of 0.33 and presents approximate resistance, hardness and texture of human biological tissue, which offers a high degree of realism in training, with the need for a slight motor adaptation when the technique is actually applied to the patient.
  • Figure 1 Illustrates the model in front view with the silicone plate (2), properly adjusted to the rigid ABS base (1).
  • the holes in the vertices, numbered 3 to 7, and the structures for training the suture and needle passing techniques are shown.
  • Figure 2 Illustrates the anterior angle of the laparoscopic training model.
  • Figure 3 Illustrates the upper slot to store the EVA sheets.
  • Figure 4 Illustrates the rear face of the model and the system for fixing it to the base of the bench simulator.
  • Figure 5 Illustrates the recommended colored dumbbell.
  • the same set of holes (9) is used to perform simple points by laparoscopy, in a calibrated way, since it is necessary to control exactly the place of entry and exit of the surgical needle.
  • the central pivot (8) is used to perform the endoloop technique and has a protrusion of the silicone plate, in order to allow the correct insertion of the suture thread for training this knot technique.
  • the dumbbell storage region (15) has a lid (14) that fits on the rigid ABS base, which is responsible for storing objects in a safe and organized manner.
  • the side silicone flaps (12) are used to train suture techniques; the lateral fissures (13) are such that they simulate the actual spacing of structures to be sutured.
  • Figure 2 illustrates the anterior angulation of the device, in order to better present the structures during training; such angulation is provided by the rigid ABS structure (1) which has an upper end that is thicker than the lower one.
  • Figure 3 illustrates the upper slot (16) in which the EVA plates are inserted, which will be used in the cutting exercise using scissors; in this exercise the plate is cut in specific regions, providing aptitude in the technique of using the instrument.
  • Figure 4 shows the posterior region of the device equipped with velcro (17), which allows the device to be attached to the laparoscopic training bench. Its correct fixation in the box provides rigidity and stability when using it.
  • FIG. 5 illustrates the dumbbell (15).
  • the dumbbell is formed by a hexagonal end (18) and a central rod (19).
  • the hexagonal end has a dimension that simulates the approximate size of a gallstone (approximately 3 millimeters); this is important, because in laparoscopic cholescistectomy the gallbladder may rupture, and if it ruptures, the surgeon must collect all the gallstones in the cavity, and when this occurs, many surgeons end up converting the operation into "open", which causes in addition to aesthetic problems (large scar), possibility of hernias in the abdominal wall.
