In order to prevent accidental needle “sticks” from a suturing device to a surgeon or staff member, a disarming or retracting sterilized suture needle must be developed that allows a reversible action when passing into and through the underlying subcutaneous tissue, dermis, epidermis, or other organ tissues in the body. The device must encompass all features of sharpness, stiffness, maneuverability, and size/shape variance as a conventional needle with the added safety of needle retraction. The goal is to permanently eliminate the risk of needle puncture and infection to the operator during procedures.

Complete
final paper and poster presentation.
·
Select
a final design.
·
Finish
working mechanistic prototypes.
·
The
poster presentation and paper were discussed during team meetings Friday,
Sunday, Monday, and Tuesday. Jeff has
started creating slides for the poster, which will be finished later tonight at
another group meeting. Briar has
finished editing the mid-semester report, except for the sections Angela and
Elizabeth will turn in at tonight’s meeting.
The PDS, abstract, and design constraints sections still need to be
revised, which will also be finished tonight, in addition to writing a new
section evaluating our final design concept.
Elizabeth is well underway with creating SolidWorks drawings for the
paper and presentation.
·
A
final design that uses fluid pressure changes to arm and disarm the needle was
selected during a meeting with Professor Tyler, on Wednesday, December 5.
·
All
prototypes (including one of the new design) are finished, except for a few
minor aesthetic additions, which Angela will complete Thursday.
·
Complete
design notebooks and peer evaluations.
·
Present
poster, hand in final paper, and go to final meeting with Professor Tyler.
