Modular origami joint operator to create bendable motions with multiple radii 145

5.5.4 Remarks

Through the analysis of related patents, we expect that the proposed MOJO transoral
tracheostomy device is significantly different from the existing prior art and patented
design. The device can be used on subjects to perform the tracheostomy procedure. The
device needs to be customized when used on subjects who require modules shorter in
length. This device must be operated by a trained operator. Prior training from a physician
is required for the use of the device if the device is to be operated. Knowledge of the entire
mode of operation, including insertion and removal procedure, sterilization of device,
disposal of waste, image capturing for review, intended use, and limitations, will be
imparted to the operator. The following outlines the envisioned step-by-step procedures of
MOJO in the process of TT.
1. Remove MOJO from the packaging and ensure that the tendons (6) and hinges (4, 5)
are fully attached and are not torn or broken. If not, a new set should be used.
2. Ensure that the device is fully slack, such that when held vertically downward, the
device is vertical, and there are no bends. If there are bending angles, adjust the
tendons until it is fully slack. If the tendons (6) snap-in the process, use a new set.
3. Remove the guide wires from the packaging and insert the wire into each of the side
lumens (3).
4. Remove the drilling wire (9) from the packaging. Insert the drilling wire through the
wire guide (1) at the center of the device. Leave an excess of about 5 cm at the top of
the device.
5. Insert the fiber-optic bronchoscope into the wire guide (2) above the drilling wire.
6. The subject should lie down on his back with the neck at the neutral position. It is
essential that the subject’s neck is not compressed, as that will affect the bending
angles that have been precalculated.
7. The anesthesiologist will give the subject local or general anesthesia. Local anesthesia
will be given during an emergency or if the procedure is done with the subject awake.
Otherwise, general anesthesia should be given.
8. Open the subject’s mouth and use a laryngoscope to identify the epiglottis and vocal
cords. Identification of the epiglottis will allow the operator to recognize the critical
airway landmarks.
9. After identification of the epiglottis and vocal cords, insert MOJO into the subject’s
mouth. With the use of the bronchoscope, slowly guide it through the oral cavity and
larynx and into the trachea. Remove the laryngoscope only when the device has
passed the vocal cords.
10. Once the device has reached the site for a tracheostomy to be performed, activate the
mechanical force and moment so that the device bends fully and is rigid. Insert the
guide wires into each of the side lumens. Insert the drilling wire through the wire
