The mechanism (100) comprises a support plate (102), a ring member (103) rotatably mounted on the support plate (102) and a plurality of flexible beam assemblies (104) configured in an inner circumference of the ring member (203). The plurality of flexible beam assemblies (104) comprises a first beam (104a) connectable to the ring member (203) and a second beam (104b) connectable to the support plate (102). the circular motion of at least one of the support plate (102) and the ring member (103). relative to each other, moves the plurality of flexible beam assemblies (104) radially inward and radially outward to selectively apply radial resistance on the simulation endoscope (301). The complaint mechanism (100) of present disclosure are joint less mechanisms which are free from backlash and friction in joints.

A vein simulator system can be used by clinicians to improve their proficiency in placing catheters such as PIVCs or in otherwise accessing a vasculature. A vein simulator system can include a simulated portion of a body, such as a simulated human arm, that includes at least one simulated vein. The vein simulator system can also include a control system, one or more sensors and one or more feedback components. The control system can leverage the one or more sensors to generate feedback during a clinician's attempt to place a catheter and can output the feedback via the feedback components, either during or after the attempt.

A surgical training model that includes a simulated tissue having a tubular shape that is connected to a tissue holder is provided. A portion of the simulated tissue overhangs the distal end of the tissue holder to simulate a cuff-like entry to the vaginal vault or resected intestine suitable for practicing laparoscopic closure of the vaginal vault, intestine or other organ via suturing or stapling. Two concentric tubular structures are also arranged over the same tissue holder. A second model includes two portions of simulated tissue that are held by two holders such that the simulated tissues are adjacent making the model suitable for practicing different types of anastomosis procedures. A third model includes two holders with a single or double tubular simulated tissue structure connected to and spanning a gap between the holders. The model isolates the step of closing a cylindrical opening for the purpose of repeated practice.

A multi-modality phantom is provided. The multi-modality phantom includes a container and an insert. The container defines an exterior that is separated from an interior space and designed to receive a tissue-mimicking medium for an ultrasound imaging process. The container further includes at least one access port formed in the container to perform the ultrasound imaging process of the interior space. The insert can be dimensioned to be selectively arranged within the interior space of the container. The insert includes imaging features arranged to simulate an environment and constructed to yield simultaneous imaging results when performing the ultrasound imaging process and at least one non-ultrasound imaging process.

Provided is an abdominal cavity simulator that allows for diverse and realistic procedure training and is easy to store and carry. The simulator is provided with a pedestal that is provided with multiple fixing portions whereto organ model fixtures are mounted; a pneumoperitoneum cover; and two side plate members that provide a space between the pneumoperitoneum cover and the pedestal for allowing the organ model fixture to be arranged therein. A first recess is provided in the pneumoperitoneum cover; a first protrusion and a second protrusion are provided in the side plate members; and a second recess is provided in the pedestal. In a state in which the direction of either the pedestal or a casing has been changed by 180°, the pneumoperitoneum cover and the side plate members can be secured to each other, and the pedestal and the side plate members can be secured to each other.

An apparatus for surgery preparation. The apparatus includes a tracking device for representing a surgical instrument, a display device for displaying a subject for surgery and one or more processors arranged to receive signals corresponding to the tracking device to determine the position of a virtual surgical instrument following the movement of the tracking device. A model is generated for three-dimensional representation of a tissue corresponding to the subject for surgery, the model having plurality of tissue elements arranged to together represent the tissue. A method for utilizing a tracking device for representing a surgical instrument is also disclosed.

A chest tube insertion test device for performing a chest tube insertion training procedure at least partially encloses an insertion tool and includes a microcontroller communicatively coupled to one or more force-sensing resistors. The one or more force-sensing resistors convert an insertion force into a voltage signal sent to the microcontroller. A feedback generator compares the chest tube insertion force to one or more predetermined threshold values and provides feedback to a trainee. The feedback can include an instruction to increase, decrease, or maintain the chest tube insertion force. The feedback is one or more audio cues and/or one or more visual cues (e.g., represented by audio files and/or visual data files stored at the chest tube insertion test device). The chest tube insertion test device detects an insertion force rate of change indicating that the insertion tool has passed through an inner pad of the training model.

A reusable safety syringe training device is provided. The device comprises a syringe contained within a syringe protective member. The syringe protective member is movable vertically within an outer protective sheath from a first position to a second position and back to the first position. In the first position, the device is in an injection-ready position with the needle exposed and the syringe protective member in a locked vertical position with respect to the outer protective sheath. In the second position, the device is in a post-injection position such that the syringe protective member is no longer vertically locked with respect to the outer protective sheath and has moved vertically upward thereby rendering the needle within the outer protective sheath. The plunger carries a release flange sufficient to engage release latches that otherwise retain the syringe protective member in the first position. The release flange engages that release latches when the user pushes the plunger down to effectuate the injection. Once pressure is removed from the plunger after the injection has concluded, a springe mechanism drives the syringe protective member upwards to the second position. The user can then turn the plunger such that the release flange is no longer able to engage the release latches and push the plunger back down to lock the syringe protective member in its first position. The user is then able to pull the plunger back up while the syringe protective member remains locked, turn the plunger back to a position where the release flange is in a position to engage the release latches again, and perform another injection.

A renal hilum surgical simulation system is provided. The renal hilum surgical simulation system includes simulated tissue layers and simulated renal organs and/or vasculatures. The renal hilum surgical simulation system is adapted for but not limited to laparoscopic donor nephrectomy surgical procedures.
