Cranial Burr Hole Introducer For Surgical Access

A medical device for accessing soft tissue of the brain with a surgical access device, comprising:

• a cranial burr hole device configured to be arranged on a patient;
• and
• a socket arrangement including:
• a socket top defining a socket top opening and at least one camera opening separate from and non-concentric with the socket top opening,
• a socket bottom defining a socket bottom opening and at least one camera opening separate from and non-concentric with the socket bottom opening, the socket bottom configured to be received by a burr hole device opening in the cranial burr hole device and to mate with the socket top such that one of the at least one camera opening of the socket top aligns with one of the at least one camera opening of the socket bottom to define a channel through the socket arrangement that is configured to receive a camera so that the camera may access a surgical site;
• and
• a ball having a ball portion and a lip extending upward from the ball portion, the ball portion seated within the socket bottom and the lip received by the socket top,
• wherein the socket top opening, the socket bottom opening, and the lip are configured to receive the surgical access device when the cranial burr hole device is arranged on a patient.

A method for accessing soft tissue surgical site of the brain, the method comprising:

• arranging a cranial burr hole device on a patient, the cranial burr hole device including a burr hole device opening receiving a socket bottom of a socket arrangement, the socket arrangement including:
• a socket top defining a socket top opening and at least one camera opening separate from and non-concentric with the socket top opening,
• the socket bottom defining a socket bottom opening and at least one camera opening separate from and non-concentric with the socket bottom opening, the socket bottom configured to mate with the socket top such that one of the at least one camera opening of the socket top aligns with one of the at least one camera opening of the socket bottom to define a channel through the socket arrangement;
• and
• a ball having a ball portion and a lip extending upward from the ball portion, the ball portion seated within the socket bottom and the lip received by the socket top;
• inserting a delivery sleeve assembly into the socket top opening, the socket bottom opening, and the lip;
• accessing the soft tissue of the brain with a surgical access device inserted through the delivery sleeve assembly;
• and
• accessing the surgical site with a camera inserted through the channel of the socket arrangement.
