Abstract

Surgical Device companies that produce and sell trocars, obturators, and combinations of the two generally require some way to protecting the tips of such devices during packaging/shipping. However, due to the disposable nature of this packaging, it is generally desired to minimize the cost and diversity of such packaging. The idea presented herein followed these four basic design constraints: 1. Should have the same insertion and removal forces as the current tip protector designs 2. Must fit in the current exterior packaging 3. Material must be capable of both Gamma and ETO sterilization 4. If possible one solution for all sizes will be preferred but it is not a constraint

ECONOMICAL TROCAR TIP PROTECTOR - DOUBLE FUNNEL DESIGN

Surgical Device companies that produce and sell trocars, obturators, and combinations of the two generally require some way to protecting the tips of such devices during packaging/shipping. However, due to the disposable nature of this packaging, it is generally desired to minimize the cost and diversity of such packaging. The idea presented herein followed these four basic design constraints:


1. Should have the same insertion and removal forces as the current tip protector designs


2. Must fit in the current exterior packaging

3. Material must be capable of both Gamma and ETO sterilization

4. If possible one solution for all sizes will be preferred but it is not a constraint

DESCRIPTION

This tip protector will be able to accept any size trocar/obturator (i.e. 5, 8, 11, 12, & 15mm) by virtue of its conical design, which will press-fit against the tip of any size trocar/obturator and flex around it. The design will be flexible enough to bend over 180 degrees to hold the trocar and obturator side by side in the same packaging. However, once removing from the packaging, the nurse will be able to pull apart the trocar and obturator in-line with each other, separating them from the tip protector. This device will much easier to manufacture than previous tip protectors and may even be able to be an off-the-shelf elastomeric part due to its simple double-funnel shape.
