Cranial burr hole introducer for surgical access

1 . A medical device for accessing soft tissue of the brain, comprising:

a cranial burr hole device configured to be arranged on a patient;

a socket arrangement including:

a socket top defining a socket top opening,

a socket bottom defining a socket bottom opening and configured to be received by a burr hole device opening in the cranial burr hole device, 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;

a delivery sleeve assembly including a sheath configured to receive a surgical access device, wherein the socket top opening, the socket bottom opening, and the lip are configured to receive the sheath when the cranial burr hole device is arranged on a patient; and

a depth stop arranged on the sheath of the delivery sleeve assembly configured to be selectively adjusted along the sheath to an incremental depth marker associated with the location of a surgical site,

wherein the socket top defines at least one camera opening separate from and non-concentric with the socket top opening and the socket bottom defines at least one camera opening separate from and non-concentric with the socket bottom opening, the socket top being configured to mate with the socket bottom 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 the surgical site via the socket arrangement.

2 . The medical device of claim 1 , wherein the delivery sleeve assembly includes an adaptor assembly configured to fix the delivery sleeve assembly to the surgical access device.

3 . The medical device of claim 2 , wherein the adaptor assembly includes a sheath adaptor defining a channel configured to receive the sheath and an irrigation socket configured to receive an irrigation port.

4 . The medical device of claim 3 , wherein the adaptor assembly includes an adaptor cap configured to cover at least a portion of the sheath adaptor and receive a resection tool of the surgical access device.

5 . The medical device of claim 4 , wherein the sheath adaptor is configured to receive an O-ring, and wherein the adaptor cap is configured to seal the O-ring within the sheath adaptor in an assembled state.

6 . The medical device of claim 1 , wherein the socket bottom forms a conical shape configured to mimic the ball portion of the seated ball.

7 . The medical device of claim 1 , wherein the ball portion of the ball is configured to be received by at least a portion of the socket bottom opening.

8 . The medical device of claim 1 , wherein the socket bottom creates a seal with a membrane of the cranial burr hole device.

9 . The medical device of claim 1 , wherein the socket top defines a fastener opening configured to align with at least one burr hole device attachment opening, each configured to receive a fastener to attach the socket arrangement to the cranial burr hole device.

10 . The medical device of claim 1 , wherein at least one of the socket top and socket bottom are attached to the cranial burr hole device via an adhesive.

11 . The medical device of claim 1 , wherein at least one of the socket top and socket bottom are attached to the cranial burr hole device via a friction fit mechanism.

12 . The medical device of claim 1 , wherein at least one of the socket top and socket bottom are attached to the cranial burr hole device via a screw and threaded opening.

13 . The medical device of claim 1 , wherein the cranial burr hole device comprises:

a cylinder having opposed first and second open ends and defining a volume extending between the first and second open ends, the first open end configured to affix to a cranium; and

a membrane positioned across the second open end and defining the burr hole device opening, wherein the socket arrangement is received in the burr hole device opening of the membrane to create a seal with the membrane and such that the volume defined by the cylinder is positioned between the cranium and the socket arrangement when the first open end is affixed to the cranium.

14 . A medical device for accessing soft tissue of the brain, comprising:

a socket arrangement including a socket top defining a socket opening, wherein the socket top defines at least one camera opening separate from and non-concentric with the socket opening, the at least one camera opening configured to receive a camera so that the camera may access a surgical site via the socket arrangement;

a cranial burr hole device configured to be arranged on a patient, the cranial bur hole device including:

a cylinder having opposed first and second open ends and defining a volume extending between the first and second open ends, the first open end configured to affix to a cranium, and

a membrane positioned across the second open end and defining an opening, wherein the socket arrangement is received in the opening of the membrane to create a seal with the membrane and such that the volume defined by the cylinder is positioned between the cranium and the socket arrangement when the first open end is affixed to the cranium;

a delivery sleeve assembly including a sheath configured to receive a surgical access device, wherein the socket opening is configured to receive the sheath when the cranial burr hole device is arranged on the patient; and

a depth stop arranged on the sheath of the delivery sleeve assembly configured to be selectively adjusted along the sheath to an incremental depth marker associated with the location of the surgical site.
