Suture Needle Cover

The Suture Needle Cover secures needles during surgery, allowing them to be left safely within the surgical field while also protecting medical professionals and patients from accidental percutaneous injury.


Many surgical and trauma wounds need to be closed in multiple stages, requiring needles to be left in the operating field. However, keeping an unprotected needle in the surgical field presents a risk of accidental penetrating injury, or percutaneous injury, to both health care providers and patients.

Suture needles are a frequent cause of injury in surgical settings. Unprotected needles increase the risk of accidental needle-stick injuries during surgery or trauma repair.

Health care providers and surgical staff are at risk from exposure to unprotected needles contaminated by patients’ blood, and patients, in turn, are at risk from exposure to the blood of injured staff. This increases the risk of transmitting bloodborne pathogens, including hepatitis B virus (HBV), hepatitis C virus (HCV) and human immunodeficiency virus (HIV).


The Suture Needle Cover captures and encloses suture needles still attached to the surgical site in order to protect physicians, nurses or patients from accidental needle-stick injuries while personnel attend to other parts of the surgical procedure or trauma repair.

The invention includes a range of small containers in various sizes and shapes to secure suture needles. After physicians begin suturing, they can place the needle in the holder, which has hinges that allow the container to be closed over the needle. A latch secures the cover of the holder, causing the container to enclose the needle with the suturing material still attached, keeping the needle sterile.

With the Suture Needle Cover health care professionals can begin suturing and then secure the needle within the holder until the procedure requires closing the wound.
