Abstract

An intracranial access device includes a housing having an operator-facing side and a patient-facing side and an opening therethrough extending from the operator-facing side to the patient-facing side. The device further includes at least one fastener configured to secure the device to a cranium of a patient. The device further includes a drill mounted to a surface of the housing and a cauterizer. The device may further include a number of sensors arranged on the patient-facing side of the housing and configured to identify a hemorrhage location.

First claim

What is claimed is:

1. An intracranial access device, comprising:
a housing having an operator-facing side and a patient-facing side and an opening therethrough extending from the operator-facing side to the patient-facing side, configured to accommodate access to a treatment area, wherein the housing includes a surface positioned on the operator-facing side;
at least one fastener configured to secure the device to a cranium of the patient;
a drill mounted to the surface and structured to penetrate into the cranium; and
a cauterizer mounted to the surface and configured to cauterize the treatment area.

2. The intracranial access device of claim 1 , wherein the at least one fastener comprises adhesive.

3. The intracranial access device of claim 2 , wherein the at least one fastener further comprises a plurality of bone screws.

4. The intracranial access device of claim 2 , wherein the adhesive comprises open-cell foam, optionally comprising cyanoacrylate.

5. The intracranial access device of claim 1 , further comprising a sealing member disposed on the patient-facing side of the housing and configured to seal the device to a patient, and optionally further comprising a storage cap configured to protect the sealing member from contaminants until use.

6. The intracranial access device of claim 5 , wherein the sealing member includes closed-cell foam.

7. The intracranial access device of claim 1 , wherein the cauterizer comprises an electrocautery element and a plunger, wherein the device optionally further comprises a power source configured to power the electrocautery element, and wherein operation of the cauterizer includes depressing the plunger such that the electrocautery element contacts the treatment surface.

8. The intracranial access device of claim 1 , further comprising a membrane configured to seal the opening, the membrane being penetrable to provide access to the treatment area.

9. The intracranial access device of claim 1 , wherein the cauterizer is axially aligned with the opening.

10. The intracranial access device of claim 1 , wherein at least a portion of the housing is selectively rotatable to facilitate alternating between drilling and access to the treatment area.

11. The intracranial access device of claim 1 , wherein the housing includes a user interface to facilitate locking a rotational position of the surface.

12. The intracranial access device of claim 1 , further comprising:
a retractor housed within the housing including retractor blades structured to cut into the scalp; and
a plurality of sensors arranged on the patient-facing side of the housing and configured to identify a hemorrhage location.

13. The intracranial access device of claim 12 , further comprising a sealing member disposed on the patient-facing side of the housing and configured to seal the device to a surface of a patient's head.
