Definitions

  • the present invention relates to a head frame for supporting a probe for imaging, therapy or both and, more particularly, a head frame having a member conformal to the head, thereby serving to stabilize the support.
  • Ultrasound transducer and probe placement on a patient's skull requires specialized skills, as diagnostic-grade imaging or clot targeting is difficult to achieve through the small ultrasound window that the temporal bone provides. Finding the best probe position on the skull, and finding the best probe orientation and alignment to acquire diagnostic-grade ultrasound images is difficult. In particular, the temporal bone thickness is irregular. Thus, small changes in angular position can shift the target region out of the probe's beam, requiring probe re-positioning/re-alignment. Holding the probe steady (by hand) while adjusting imaging parameters (presumably with the other hand) is also difficult. Finally, holding a probe immobile for extended periods of time, as required for an STL treatment, for example, or to monitor brain blood flow for extended periods, is almost impossible without the use of a custom headset.
  • the helmet is configured for keeping a pair of ultrasound probes in contact with the temporal regions of both sides of the head.
  • a liner inside the helmet wraps around a circumference of the head. With the probes positioned inside the liner, the liner functions as a transcranial headset.
  • the probes have matrix arrays usable for electronic steering.
  • the probes are utilizable for imaging or therapy, including imaging guidance for steering a therapy beam. Once it is seen, via the imaging guidance, that the probes are suitably positioned, the helmet liner headset can be adjustably secured in place by an adjustment knob.
  • TCD trans-cranial Doppler
  • STL sonothrombolysis
  • All of these applications require a solid, cost- effective, and simple-to-use headset, which can reliably hold the probe immobile in place for longer periods of time and provide for easy probe adjustment. This allows the clinician to focus more on obtaining quality brain images for a good diagnosis, or enabling a targeted ultrasound treatment spanning several hours.
  • headsets offering some of these features are available commercially, the headsets tend to be application-specific and difficult to use.
  • a head frame for a head of a medical patient includes support for a probe configured for imaging, therapy, or both imaging and therapy.
  • the frame also includes a conformal member configured for placement conformally against an outer surface that is higher on the head than the forehead. The frame is configured such that the conformality serves to keep the probe in place against the head.
  • Fig. 1 is a perspective view of an exemplary head frame holding a probe in place against the head of a patient, in accordance with the present invention
  • Fig. 2 is a perspective, exploded view of the head frame of Fig. 1;
  • Fig. 3 is a perspective view of one example of a probe holder usable for the head frame of Figs. 1 and 2, showing how a probe is attachable to the probe holder, in accordance with the present invention.
  • Fig. 4 is a perspective view of an alternative probe adaptor attachable to a probe holder usable for the head frame of Figs. 1 and 2, in accordance with the present invention.
  • Figs. 1 and 2 depict, by way of illustrative and non-limitative example, a head frame 100 for supporting a probe 102 for imaging, therapy or both. Except for headbands which span a head 104 from left to right, the head frame 100 has, for every component for the left side of the head, a corresponding component that symmetrically corresponds with the right, i.e., opposite, side of the head. The components will therefore now be described for one side of the head.
  • the head frame 100 includes a conformal member, or "headpiece", 106; an elongated, X-Y positioning probe holder 108; and a hand-turnable X-Y position knob 110 for releasably attaching them together.
  • the probe holder 108 has, at one end, a circular or round opening or orifice 112 for the probe 102 and, at the other end, a longitudinal slot 114 through which the probe holder is secured to the headpiece 106 by the X-Y positioning knob 110 applied at a pivot point 116. By turning the knob 110, the user can adjust the tightness of fixation of the probe holder 108 to the headpiece 106.
  • the head frame 100 also features a hand-turnable rotation/angulation knob 118 for adjusting the size of the circular opening 112.
  • the headpiece 106 is conformal to the shape of the head 104, and is rigid although not necessarily inflexible. The conformality distributes the load and torque of the probe 102 across a large area of the patient's head 104.
  • the headpiece 106 has a large contact area of at least 25 square centimeters (cm) of an outer surface that is higher on the head 102 than the middle of the forehead, i.e., mid-forehead. These factors all serve to keep the probe 102 held by the probe holder 108 in place against a temporal bone window 120 of the head 102.
  • the temporal bone window 120 is a location on the skull where the attenuation of ultrasound signals is the smallest, allowing for maximum ultrasound transmission into the brain.
  • the headpiece 106 also has a portion that is not above mid-forehead.
  • the front and rear headbands 130, 134 extend down, as seen in Fig. 1, to an area of the head 104 that is laterally alongside the lower forehead, and a portion of the headpiece attaches to the front and rear headbands.
  • the headpiece 106 is designed to provide ample temporal bone window access. It has, for this purpose, U-shaped indentation or cutout extending to behind the ear adjacent the window 120. This cutout is large enough to make sure that the temporal bone window 120 will always be exposed, and accessible by the ultrasound probe 102, somewhere within the region surrounded by the cutout.
  • the interior of the headpiece 106 is padded, as denoted by the reference numeral 124, to accommodate differences in skull geometries and increase the wearer's comfort.
  • the padding material could be foam or rubber for example.
  • the probe holder 108 has a flat back surface that mates with a flat outer surface 126 of the headpiece 106, regardless of its position with respect to the headpiece. This is better seen in Fig. 2. This large surface contact provides friction that ensures that, once locked in place, the probe holder 108 is not going to move with respect to the headpiece 106. This results in a stable and strong probe position.
  • the user By varying the tightness of the X-Y position knob 110, the user is able to make smaller and more precise adjustments to the position of the probe 102, as he or she hones in on the targeted, or imaging-guidance indicated, probe position and orientation on the patient's skull, as required for STL, TCD or other brain imaging and/or therapeutic applications. Once the destination position is reached, the knob can be tightened fully.
  • Wide headbands 130, 132, 134 further increase the contact area of the head frame 100 with the head 104, increasing stability, but distributing the tension evenly and thereby increasing patient comfort.
  • the headpiece 106 has slots 136, 138, 140, for insertion of the respective headbands 130-134 that extend from one slot to the corresponding slot of the other headpiece 106.
  • the headbands 130-134 can be made out of elastic material or a hooking type of fastening tape such as VelcroTM Or they can be made of a combination of both materials.
  • a manual length-adjustment provision to selectively increase or decrease length, and in effect change the distance between the two headpieces 106, allows differently sized heads to be accommodated.
  • the front headband 130 may have a tension adjustment knob 142 for this purpose.
  • a mechanically adjustable, relatively inelastic headband allows for truly tightening down the overall head frame 100 on the patient's skull, once the prior length adjustments to the top and back headbands 132, 134 have been made.
  • the head frame 100 can have mirror-image symmetry with respect to both sides of the head, provided that the tension adjustment knob 142 is centered on its front headband 130.
  • Equivalent probe support on both sides of the head 104 allows for interchangeability of probes, and the use of two probes concurrently or a single probe.
  • a probe holding capability is designed based on a friction-regulated spherical envelopment of a matingly spherical probe adaptor designed for holding differently sized and shaped probes.
  • Application-specific ultrasound probes are fixed to the probe holder 108 using a clam-shell-shaped adaptor 144 consisting of two contoured spherical sections 146 that firmly hold the probe 102 using their inside surface. This is shown in more detail in Fig. 2. The two sections 146 also firmly hold the assembly in place in the probe holder 108 using their outside spherical surface 146.
  • the circular opening 112 which mates with the outside or exterior spherical surface 146 of the adaptor 144, likewise has the shape of a spherical section.
  • a wide variety of adaptors 144 can be provided with different interiors or inside surfaces particular to the respective probes to be used. The probe must be small enough in cross-section to fit within the circular opening 112, but the selection of probes is not otherwise limited. For larger probes, a probe holder with a larger opening could be employed. All told, given the inter-releasability of components of the head frame 100, there is great flexibility in accommodating different probes.
  • the spherical mating of the adaptor 144 to the probe holder 108 allows the probe 102 to be rotated into a targeted, or optimal, orientation.
  • the hand-turnable rotation/angulation knob 118 is in its open/loose position, allowing smooth probe angulation and rotation by the user.
  • the knob 118 is tightened, pressing the regions surrounding the clam-shell sections 146 against them, firmly locking the probe 102 in place.
  • the large contact surface between the clam-shell sections 146 and the inside surface of the circular opening 112 further contributes to a strong and stable positioning mechanism.
  • a flexible member 150 is made up of elastic material more flexible than that of the remainder of the probe holder 108.
  • the probe holder 108 is slightly bendable at this location which acts as a spring.
  • the flexible member 150 is configured for, via the probe holder 108, urging the probe 102 against the head 104.
  • Z positioning can also be accomplished by replacing the clamshell halves 146 with a different set, these having a different inner surface contour, which would hold the ultrasound probe 102 either further in (-Z) or further out (+Z) as the 'default' clam-shell.
  • the head frame 100 includes a set of adaptors 144 specific to a given probe 102 and having different, inside, Z-positioning configurations for holding the probe inward to corresponding extents.
  • a length of between 4 and 6 cm for the slot 114 allows the head frame 100 to always be positioned in such a way that the ultrasound transducer of the probe 102 can always be positioned on the temporal bone window 120.
  • the flat outer surface 126 of the headpiece 106 can be expanded on the headpiece so that the surrounding curved surfaces are replaced by a single flat surface. This maintains stability even when positioning the probe holder 108 on the outer limits of the U-shaped indentation 122.
  • a larger surface area can be added to the hand-turnable X-Y position knob 110.
  • a knob 302 can be provided with three rotary projections 304, 306, 308. This makes it easier for the user to apply sufficient attachment strength that prevents probe motion with respect to the head 104.
  • the X-Y position knob 110 can instead by implemented as a wheel, regularly indented along its circumference to make the user's grip firm.
  • buttons squeezable together with one hand, to replace the slot 114 and pivot point 116.
  • the buttons would project out from the narrow sides of the probe holder 108 which instead releasably attaches to the headpiece 106 by a generally downward projection that slides fittingly into a mainly vertical slot at the top of the headpiece. Squeezing together the buttons acts as a release that allows for X-Y positioning of the probe holder 108.
  • the headband attachment mechanism can be a button.
  • the front headband 130 can have a button hole at each end for attachment to the headpieces 106.
  • the button allows for easy replacement of individual headbands, e.g., for cleaning or replacement.
  • Another advantage is that the angle of the headband can vary with respect to the headpiece 106, since the headband can rotate around the button mechanism. Thus, comfort is further increased, and the head frame 100 is wearable for prolonged periods of time by people with differently shaped skulls.
  • two opposite notches 310, 312 in the circular opening 112 facilitate attachment and removal of the probe 102.
  • the opening 112 has a gap 314 with two sides 316, 318, such that urging the two sides toward one another tightens the opening, and urging the sides apart widens the opening.

  • the probe 102 can be turned by 90°, as represented by the curved arrow 326, so that the probe axially points to the center of the circular opening 110.
  • the opening 112 has laterally opposing notches 310, 312 shaped to conform to a ring-shaped structure 144 and by which the structure is insertable into the opening.
  • the opening 112 is configured for allowing the structure 144, once inserted, to pivot into concentric alignment with, and containment within, the opening. The resulting concentric alignment provides a typical orientation employed during use of the probe 102.
  • the probe 102 will no longer be removable from the probe holder 108, and will be securely held in place, with easy adjustment capabilities.
  • the above-described threaded pin is slid in place after the probe 102 has been pushed in and rotated up.
  • the opening 112 is then tightened via the rotation/angulation knob 118.
  • this process is repeated in reverse order. It is simple, intuitive, and strong.
  • Other embodiments providing this functionality include the design of an opening in the probe holder 108 that is likewise slightly smaller than the outside diameter or the adaptor 144, but with the probe holder having sufficient elasticity around the opening 112 to allow insertion of the probe 102 and adaptor 144 without relying on notches. More specifically, with the rotation/angulation knob 118 removed, the user would press the adaptor-engaged probe into the opening 110; the opening would temporarily increase in size due to material flexibility and the absence of the knob.

  • the probe holder 108 is therefore configured for, under insertion pressure of a spherical object 144 against the circular opening 112 to gain entry into the opening, flexing to widen the opening to potentially permit insertion of the object and further configured for, in case of the insertion, securely holding the object within the opening.
  • the entire head frame 100 consists of 10 parts: 2 headpieces 100; 2 adjustable headbands 132, 134; the front adjustable headband 130; the probe holder 108; an X-Y positioning knob 110; the 2 spherical sections 146 of the adaptor 144; and the rotation/angulation knob 118.
  • Fig. 4 shows, as an alternative version, an exemplary probe adaptor 400 that is user-expandable to lock in place in the circular opening 112.

  • the adaptor 400 includes a probe sleeve 404, an O-ring 408, a spherical friction surface 412, and probe levers 416, 420.
  • the probe sleeve 404 allows for adaptability to a variety of ultrasound probes. It is similar to the adaptor 144 of Figs. 1 through 3 in this way, and likewise may be in two separate parts 424, 428. However, its outer surface can be, for example, cylindrical and need not be spherical.
  • the outer surface is designed to attach it rigidly to the concentric, surrounding O-ring 408.
  • the spherical friction surface 412 is expandable (as it consists of several individual pieces, held in place by the O-ring 408) to lock the adaptor 400 in place inside the circular opening 112, and is activated by the probe levers 416, 420.
  • the O-ring 408, or a similar flexible structure holds in place the various components, for example the sleeve 404, friction surface 412, and the levers 416, 420. It provides the friction to hold the adaptor 400 firmly in the probe holder. It can easily be removed to disassemble the adaptor 400 for cleaning or disinfection, or exchange or replacement of the probe 102.
  • the friction surface 412 contracts. This allows the user to first place the adaptor 400, with the held probe 102, within the circular opening 112. The contracted state further allows the user to freely rotate and angulate the probe 102 within the probe holder 108, to orient it properly for its targeted or intended use (e.g., diagnostic imaging or STL treatment).
  • the levers 416, 420 are squeezable together by a single hand, to lock the adaptor 400 in place in the probe holder 108.

  • the wedge 436 when pushed up forces outward the spherical friction surface 412, thereby locking the probe 102 in place.
  • Partially closing the probe levers 416, 420 applies enough friction between the probe holder 108 and the spherical friction surface 412 of the probe adaptor 400 to allow for probe positioning: angulation and rotation with a single hand. Once the desired probe orientation and angulation has been achieved, the levers 416, 420 are closed all the way, to hold the probe 102 firmly in place within the probe adaptor 400.
  • ultrasound coupling gel can be re-applied, or an ultrasound coupling pad can be replaced, without the need for removing the head frame 100.
  • the probe holder 108 can be swung out to one of the two horizontal extremes, thereby allowing user access to the full temporal bone window 120.
  • the probe holder 108 could be removed altogether.
  • probe positioning is done in a stepwise/sequential manner. Initially, the rotation/angulation knob 118 is in its locked position, and the X-Y position knob 110 is in the loose/open position. This allows the user to adjust the horizontal and vertical probe position with one hand, to locate the best imaging window on the temporal bone. Then, the X-Y position knob 110 is tightened, locking the probe position in place, and the rotation/angulation knob 118 is loosened. This allows the user to fine-tune the probe rotation and angulation against the patient's skull to possibly improve the image/coupling, etc. When this is achieved, the rotation/angulation knob 118 is fully tightened, and the above procedure repeated, until the desired probe position has been achieved.
  • both the X-Y position knob 110 and rotation/angulation knob 118 are in the open/partially open position. This allows for full XY angulation/rotation probe positioning all at the same time.
  • the probe 102 can be manipulated with one hand in all degrees of freedom in order to find its required position on the patient's temporal bone. Once this has been achieved, both knobs 110, 118 are tightened, fixing the probe in place (with one or two hands).
  • the head frame may be employed in intensive care unit (ICU) continuous monitoring.
