Medical clamps currently available are not efficient nor are they sufficiently precise in closure and alignment of the edges of an incision or wound. Many available designs are difficult to use and handle, especially in situations where repeated opening and closure of an incision or wound is required. The functional short-comings of existing clamp designs may result in surgical complications, such as excess loss of fluids and pressure and hemostasis during some procedures. These functional deficiencies may increase the difficulty and expense of a surgery or altogether limit the ability to perform some procedures. 

This clamp design is functionally superior in its ease of use and capability to precisely keep in alignment incision or wound margins during repeated opening and closure.  As a result, a surgeon using this clamp is able to quickly open or close an incision or wound, as needed. This ability is a critical attribute where there is need to insert instruments, sometimes repeatedly, through an incision or wound. These superior functionalities reduce potential for fluid loss, which is especially critical in procedures such as intraocular surgeries where maintaining fluid balance avoids serious complications. Excessive loss of intraocular fluid balance during surgery can result in collapse of the eye, hemorrhage, and retinal detachment. This clamp design may improve outcomes of many surgeries and potentially enable new procedures presently too risky to undertake with current clamp devices. 

This invention is available for licensing and/or collaborative development partnerships.

Competitive Advantages:

  • Maintains more precise alignment of the wound margins
  • Permits easy reopening and entry into the incision or wound and repeated closure
  • Reduces fluid loss from wound or incision, helps maintain hemostasis
  • Guides and controls placement and depth of sutures

Commercial Applications:

  • Intraocular surgeries requiring incision in sclera
  • Rapid closure of traumatic wounds
