Abstract
The present disclosure concerns systems and methods related to an adjustable surgical dilation device for the mechanical dilation of an anatomical opening, including, but not limited to, an endoscopic or robotic port. In specific embodiments, this device may create and expand an anatomical opening with a novel petal-like mechanism. In specific embodiments, this device may be utilized in laparoscopic procedures including, but not limited to, thyroid or parathyroid removal.
Claims35
A device for dilation of a surgical path, comprising:
- a dilator head positioned at the distal end of the device, comprising:
- an insertion tip positioned at the distal end of the dilator head, wherein the insertion tip is configured to create and/or expand a surgical path in an individual in need;
- and
- a dilator petal assembly positioned at the proximal end of the insertion tip, wherein the dilator petal assembly comprises two or more dilator petals;
- and
- a dilator body connected to the proximal end of the dilator head;
- wherein the device is configured to extend the dilator head in the closed state into the surgical path, wherein the device is configured to transition the dilator head into the open state by opening the dilator petal assembly radially outward from the dilator head,
- wherein the device is configured to dilate the diameter of the surgical path by retracting the dilator head in the open state from the surgical path, and
- wherein the insertion tip flares out from a conical point at the distal end of the insertion tip to a maximum diameter before tapering to a flat edge at the proximal end of the insertion tip.
