Creating a better fertility diagnostic device
Combining two procedures into onesTBRIC used SOLIDWORKS when working with CooperSurgical, Inc. on the development of a new device for conducting sonohysterosalpingography (sono-HSG), an ultrasound exam for studying the contour of the uterine cavity and the patency of the fallopian tubes to determine potential fertility issues. “Using SOLIDWORKS, we were able to cut development time by 30 percent,” Simoes stresses. “Medical device development takes more time than designing other types of products because we have to validate every step, both in software and through the production of prototypes to support usability studies to comply with U.S. Food and Drug Administration [FDA] requirements. The combination of integrated SOLIDWORKS tools and the ability to conduct testing all within the same facility shortened the process and accelerated time-to-market.” ABBI (Air Bubble Based Infuser) is a single-use device that facilitates two procedures as part of an initial female fertility evaluation: a sono-HSG for tubal patency and an SIS for uterine structure. Both are office-based procedures using existing ultrasound systems and an SIS catheter. These procedures can be performed in an IVF center or OB/GYN practice that offer fertility screening.
Surfacing Advances ErgonomicsTBRIC made extensive use of SOLIDWORKS surfacing tools during the development of the sono-HSG ABBI device to refine its ergonomic characteristics. For example, because physician hand sizes vary widely, TBRIC needed to design the device to accommodate different grip positions on the handle. “We used a lot of surfaces to get the ergonomic shape, produced prototypes for use by doctors, and then utilized the physicians’ input to tweak the design to make it more ergonomic,” Simoes explains. “SOLIDWORKS surfacing capabilities were more effective and efficient for modifying the surfaces on the handle. With other surfacing packages, modifying one feature means the entire design has to change. Because SOLIDWORKS is parametric, it was faster and easier to modify surfaces in the design.”
Optimizing Production MoldsTBRIC also leveraged SOLIDWORKS tools to improve product quality and manufacturing processes. The team used SOLIDWORKS Plastics mold-filling simulation software to optimize the injection mold for the handle, which is made from a special ABS plastic that deforms under sterilization to ensure single usage of the device. “Our injection-mold specialist used SOLIDWORKS Plastics software to determine where the gating locations should be to minimize the appearance of sink marks and knit lines,” Simoes says. “The simulations also enabled us to understand that by keeping the device in the mold a little longer and at higher pressure, we could contain the sink marks to an acceptable level. SOLIDWORKS tools saved us time while improving quality.”
