[0004] This application claims priority to U.S. Provisional Application No. 62 / 957,003, filed on January 3, 2020, which is incorporated by reference in its entirety into this application. Technical Field

[0005] The present application relates to an ultrasonic finger probe and method thereof. Background Art

[0006] Ultrasound probes can be large, cumbersome, and difficult to maneuver, which in turn can make it difficult to image the desired tissue. Relatively small ultrasound probes are available, but such ultrasound probes can also make it difficult to image the desired tissue due to their small size and lack of features for maneuvering the ultrasound probe or applying sufficient pressure to it for proper acoustic coupling.

[0007] Disclosed herein is an ultrasonic finger ultrasound probe and method thereof that solve at least the above-mentioned problems. Summary of the Invention

[0008] Briefly, an ultrasound probe for an ultrasound imaging system is disclosed herein. The size and configuration of the ultrasound probe are designed so that it can be supported and easily used with one finger on a single hand of a user of the ultrasound imaging system (e.g., a clinician). This configuration enables the remaining fingers on the user's hand to be used for other purposes, including applying traction to the patient's skin surface near the imaging site and providing tactile comfort to the patient. With the ultrasound probe supported by as little as a single finger, the ultrasound probe can be easily positioned by the user in an appropriate orientation against the skin surface during the imaging process.

[0009] Disclosed herein is an ultrasound probe that, in some embodiments, includes a body, a lens, a stabilizing portion of the body, and a finger grip portion of the body. The lens is disposed in a cutout of the body and designates a head portion of the ultrasound probe. The lens is configured to allow ultrasound signals to pass therethrough. The stabilizing portion comprises a longitudinally extending portion of the body extending away from the head portion of the ultrasound probe. The stabilizing portion of the ultrasound probe is configured to stabilize the ultrasound probe on a patient's skin surface without assistance from a user of the ultrasound probe. The finger grip portion comprises a generally transversely extending portion of the body extending away from the head portion of the ultrasound probe. The finger grip portion of the ultrasound probe is configured to enable the user to grasp and manipulate the ultrasound probe with no more than two or three fingers of one hand during use of the ultrasound probe.

[0010] In some embodiments, the ultrasound probe further includes a cable conduit formed from a curved extension of the body extending away from the stabilizing portion and the head portion of the ultrasound probe. The cable conduit is configured to accommodate a distal end portion of a power and data cable used to connect the ultrasound probe to a console. The cable conduit is further configured to maintain the power and data cable away from the head portion of the ultrasound probe.

[0011] In some embodiments, the ultrasound probe further comprises a cable sheath having a distal end portion disposed in the opening of the cable conduit. The cable sheath is configured to accommodate the distal end portion of the power and data cable at a proximal end of the cable conduit. The cable sheath is further configured to retain the power and data cable further away from the head portion of the ultrasound probe.

[0012] In some embodiments, the cable jacket is configured to attenuate the bend radius of the power and data cables around the opening of the cable conduit. Attenuating the bend radius of the power and data cables reduces the risk of damaging the power and data cables at the opening of the cable conduit where the power and data cables are most likely to bend excessively.

[0013] In some embodiments, the stabilizing portion of the ultrasound probe comprises a transverse channel extending from one side to the other of the two longitudinal sides of the ultrasound probe. The transverse channel reduces the surface area of ​​the substantially flat surface of the stabilizing portion intended to face the skin surface of the patient.

[0014] In some embodiments, the reduction in surface area of ​​the stabilizing portion of the ultrasound probe by the transverse channels facilitates movement of the ultrasound probe over the patient's skin surface by reducing the contact area between the surface of the stabilizing portion and the patient's skin surface.

[0015] In some embodiments, when the gel is between the surface of the stabilizing portion and the patient's skin surface and the ultrasound probe is removed from the patient, the surface area of ​​the stabilizing portion of the ultrasound probe reduced by the transverse channel reduces the suction between the surface of the stabilizing portion and the patient's skin surface.

[0016] In some embodiments, the finger grip portion of the ultrasound probe includes a concave surface opposite the generally flat surface.

[0017] In some embodiments, the concave surface of the finger grip portion is an extension of the concave surface of the stabilizing portion of the ultrasound probe, which is intended to face away from the patient's skin surface.

[0018] In some embodiments, the ultrasound probe is bilaterally symmetric about a plane of symmetry of the ultrasound probe.

[0019] In some embodiments, at least a portion of the body is a molded thermoplastic coupled together along a plane of symmetry of the ultrasound probe.

[0020] Also disclosed herein is an ultrasound system that, in some embodiments, includes a console and an ultrasound probe. The console is configured to process and display ultrasound images on a display of the console. The ultrasound probe includes a body, a lens, a stabilizing portion of the body, a cable guide, and a finger grip portion of the body. The lens is disposed in a notch in the body and designated as a head portion of the ultrasound probe. The lens is configured to transmit ultrasound signals therethrough. The stabilizing portion comprises a longitudinally extending portion of the body extending away from the head portion of the ultrasound probe. The stabilizing portion of the ultrasound probe is configured to stabilize the ultrasound probe on a patient's skin surface without assistance from a user of the ultrasound probe. The cable guide comprises a curved extension of the body extending away from the stabilizing portion and the head portion of the ultrasound probe. The cable guide is configured to accommodate the distal end portion of the power and data cables connecting the ultrasound probe to the console. The finger grip comprises a generally transversely extending portion of the body extending away from the head portion of the ultrasound probe. The finger grip portion of the ultrasound probe is configured to enable the user to grasp and manipulate the ultrasound probe with no more than two or three fingers of one hand during use.

[0021] The present invention also discloses a method for obtaining an ultrasound probe, which in some embodiments includes an obtaining step of obtaining an ultrasound probe. The ultrasound probe includes a body, a stabilizing portion of the body, and a finger grip portion of the body. The body has a lens disposed in a cutout of the body, the lens designating a head portion of the ultrasound probe. The stabilizing portion is composed of a longitudinal extension of the body extending away from the head of the ultrasound probe. The finger grip portion is composed of a generally transverse extension of the body extending away from the head of the ultrasound probe. The method also includes a placing step of placing the head portion and the stabilizing portion of the ultrasound probe on the skin surface of a patient. The method also includes an enabling step of enabling a detection ultrasound signal to be emitted from a piezoelectric transducer array within the ultrasound probe for ultrasound imaging into the patient's body. The method also includes a moving step of moving the ultrasound probe for ultrasound imaging through the finger grip portion using no more than two or three fingers of a single hand.

[0022] In some embodiments, the method further comprises, before the moving step, a grasping step of grasping the ultrasound probe, the grasping step comprising placing at least one of an index finger or a middle finger on a concave surface of a finger grip portion of the ultrasound probe and placing a thumb on an opposite, substantially flat surface of the finger grip portion of the ultrasound probe.

[0023] In some embodiments, the grasping step orients the palm of the single hand substantially parallel to the patient's skin surface.

[0024] In some embodiments, the method further comprises an applying step of applying ultrasound gel to the patient's skin surface prior to the placing step.

[0025] In some embodiments, the method further comprises a step of removing the ultrasound probe from the patient's skin surface. The ultrasound probe's stabilizing portion includes a transverse channel extending from one longitudinal side of the ultrasound probe to the other. The transverse channel reduces the surface area of ​​the substantially flat surface of the stabilizing portion, thereby reducing gel-induced suction between the surface of the stabilizing portion and the patient's skin surface during the removing step.

[0026] In some embodiments, the method further includes the step of connecting a power and data cable of the ultrasound probe to a console of the ultrasound imaging system. The cable extends from a cable conduit of the ultrasound probe, the cable conduit being comprised of a curved extension of the body extending away from both the stabilizing portion and the head portion of the ultrasound probe. The cable conduit is configured to keep the power and data cable away from the head portion of the ultrasound probe.

[0027] In some embodiments, the moving step does not cause the power and data cable to overbend due to attenuation of the bend radius of the power and data cable by the cable jacket. The cable jacket has a distal end portion disposed in an opening of a cable conduit from which the power and data cable extends.

[0028] In some embodiments, the method further includes a further enabling step of enabling the reflected ultrasound signal to be reflected from the patient into a piezoelectric transducer array within the ultrasound probe for conversion into an electrical signal for a corresponding ultrasound image.

[0029] These and other features of the concepts presented herein will become more readily apparent to those skilled in the art in view of the accompanying drawings and the following description, which more particularly depict specific embodiments of these concepts.

It should also be understood that the specific embodiments disclosed herein may have features that can be easily separated from the specific embodiments and optionally combined with or substituted for the features of any of the many other embodiments disclosed herein.

[0102] About the terms used herein, it should also be understood that these terms are for the purpose of describing some specific embodiments, and these terms do not limit the scope of the concept provided herein. Ordinal numbers (e.g., first, second, third, etc.) are generally used to distinguish or identify the different features or steps in a set of features or steps, and do not provide continuous or numerical restrictions. For example, "first," "second," and "third" features or steps do not necessarily appear in this order, and the specific embodiment comprising such features or steps is not necessarily limited to three features or steps. For convenience, marks such as "left," "right," "top," "bottom," "front," "back" etc. are used, and these marks are not intended to imply, for example, any specific fixed position, orientation, or direction. On the contrary, such marks are used to reflect, for example, relative position, orientation, or direction. The singular "one," "an," and "the" include plural references, unless context clearly indicates otherwise.

[0103] For example, the "proximal end," "proximal portion," or "proximal end portion" of a catheter disclosed herein includes the portion of the catheter that is intended to be near a clinician when the catheter is used on a patient. Similarly, for example, the "proximal length" of a catheter includes the length of the catheter that is intended to be near a clinician when the catheter is used on a patient. For example, the "proximal end" of a catheter includes the end of the catheter that is intended to be near a clinician when the catheter is used on a patient. The proximal portion, proximal end portion, or proximal length of a catheter may include the proximal end of the catheter; however, the proximal portion, proximal end portion, or proximal length of a catheter need not include the proximal end of the catheter. That is, unless the context indicates otherwise, the proximal portion, proximal end portion, or proximal length of a catheter is not the terminal portion or terminal length of a catheter.

[0104] With respect to, for example, the "distal end," "distal portion," or "distal end portion" of a catheter disclosed herein, includes the portion of the catheter that is intended to be near the patient or in the patient when the catheter is used on a patient. Similarly, for example, the "distal length" of a catheter includes the length of the catheter that is intended to be near the patient or in the patient when the catheter is used on a patient. For example, the "distal end" of a catheter includes the end of the catheter that is intended to be near the patient or in the patient when the catheter is used on a patient. The distal portion, distal end portion, or distal length of a catheter can include the distal end of the catheter; however, the distal portion, distal end portion, or distal length of a catheter does not necessarily include the distal end of the catheter. That is, unless the context otherwise implies, the distal portion, distal end portion, or distal length of a catheter is not the terminal portion or terminal length of a catheter.

[0105] Unless defined otherwise, all technical and scientific terms used herein have the same meanings as commonly understood by one of ordinary skill in the art.

[0106] Embodiments disclosed herein generally relate to an ultrasound probe for an ultrasound imaging system. In particular, the ultrasound probe is sized and configured so that it can be supported and easily used with one or more fingers on a single hand of a user of the ultrasound imaging system (such as a clinician). This configuration enables the remaining fingers on the user's hand to be used for other purposes, including applying traction to the patient's skin surface near the imaging site, providing tactile comfort to the patient, etc. Because the ultrasound probe is supported by only a single finger, the user can easily position the ultrasound probe on the skin surface in the correct orientation during imaging.

[0107] Furthermore, in one embodiment, the ultrasound probe is configured to enable the user's hand to be positioned substantially horizontally (i.e., parallel to) the patient's skin surface, thereby enabling relatively accurate ultrasound probe positioning (e.g., raising, placing, pressing, etc.) and scanning operations to be performed.

[0108] In one embodiment, the ultrasound probe further includes a stabilization portion to help maintain the stability of the ultrasound probe while on the skin surface.

[0109] In one embodiment, the ultrasound probe is configured to be supported and manipulated by a single finger, wherein the finger is positioned directly above the lens portion of the ultrasound probe. Such a position enables the user to easily and accurately move the ultrasound probe over the skin surface to position the ultrasound probe with the desired small movements.

[0110] Figure 1 The various components of an ultrasound imaging system 10 according to one embodiment are shown. As shown, the ultrasound imaging system 10 includes a console 20 that houses various electronic components and other components required to process and depict ultrasound images. The console 20 includes a touch screen display 30 for depicting ultrasound images and for enabling a clinician to control the device and its functions based on touch input. An ultrasound probe 40 is operably attached to the console 20 via a cable or other suitable interface (including a wireless connection), and the ultrasound probe 40 includes one or more transducer elements in its head 44 for transmitting and receiving ultrasound signals.

[0111] In one embodiment, an optional cap including a hydrogel insert can be removably attached to the head 44 of the ultrasound probe 40 to cover the lens portion thereof. The hydrogel insert provides an ultrasonically transparent interface between the ultrasound probe head 44 and the skin surface. A needle guide can also be included in the cap to help guide the needle through the patient's skin and into the blood vessel being imaged by the ultrasound imaging system 10. In another embodiment, the needle guide is included on the ultrasound probe itself. Further details regarding the ultrasound probe cap, hydrogel insert, and needle guide can be found in U.S. Publication No. 2011 / 0313293 and U.S. Patent No. 9,788,812, each of which is incorporated herein by reference in its entirety. In yet another embodiment, a sheath or covering can be removably placed over the ultrasound probe 40 to provide a sterile barrier. Note that other ultrasound imaging devices and ultrasound imaging systems than those shown here may also benefit from the embodiments described herein.

[0112] Figure 2 According to one embodiment, Figure 1 FIG. 1 is a block diagram of an ultrasound imaging system 10. In detail, a console 20, a display 30, and an ultrasound probe 40 are shown. Figure 1As shown. The console 20 includes a motherboard 64 for managing system functions and includes a processor or other general or special purpose computer, memory, storage locations, and other components for system operation. A beamformer 65 including appropriate circuitry is also operably included in the motherboard 64 to enable the generation, reception, and processing of ultrasound signals. A power button 66 is included, as well as a USB port 68 for connecting to other devices. An external power source 70 is provided, as well as a battery 72 and a speaker 74 for operation. The display 30 in this embodiment includes an LCD screen 78 or other suitable screen, and a touch screen 80 to enable touch-based functions through the display 30. Note that the ultrasound imaging system 10 may include different, fewer, or more components than those listed here, including those that enable the ultrasound imaging system to operate in a networked manner with other local or remote computing or network systems, including, for example, Wi-Fi, Ethernet, Bluetooth, and Zigbee functionality. In addition, other input modes besides a touch screen may also be used, such as keyboard or mouse input.

[0113] In operation of the ultrasound imaging system 10, the lens portion of the head 44 of the ultrasound probe 40 is placed against the patient's skin to ultrasonically image a cross-sectional slice of a blood vessel (such as a vein or other internal body tissue of the patient) beneath the skin's surface. In practice, the target location of the blood vessel imaged by the ultrasound probe 40 is positioned at a substantially vertical depth below the end of the ultrasound probe. In one embodiment, the blood vessel is imaged by the ultrasound imaging system 10 in preparation for accessing the blood vessel with a needle in preparation for inserting a catheter into the blood vessel. Although shown here as a blood vessel, the target location can be any of a variety of subcutaneous locations within the body.

[0114] Figures 3A-3D Various features of an ultrasound probe 40 including its head 44 according to one embodiment are depicted. As shown, the ultrasound probe 40 includes a body 102 defining a side surface 102A and an end surface 102B, with the head 44 of the ultrasound probe defining a distal end of the ultrasound probe body. A lens 108 is disposed at the distal end of the ultrasound probe body 102 and is configured to allow ultrasound signals to pass therethrough. A directional arrow 107 is included in the illustrated embodiment to assist a user of the ultrasound imaging system in determining proper needle placement through the surface of the patient's skin. A cable 104 is shown extending from the proximal end of the ultrasound probe body 102 to operably connect the ultrasound probe to the console 20 ( Figure 1 ), although the cable can extend from the ultrasound probe according to a variety of different configurations.

[0115] In the present embodiment, the ultrasound probe 40 includes a finger grip 110 that is configured to enable a user of the ultrasound probe to grasp, support, and manipulate the ultrasound probe with one or more fingers of a single hand of the user, while leaving one or more fingers of the user's hand free for use in other ways. In the present embodiment, the finger grip 110 includes two angled protruding elements 114 extending from opposing sides 102A of the ultrasound probe body 102. Each protruding element 114, together with a proximal portion of the side 102A of the ultrasound probe body 102, defines a concave gripping surface 118 in which the user's fingers are received to support and move the ultrasound probe 40 during system operation.

[0116] In this embodiment, the ultrasound probe 40 is placed between the index and middle fingers of one hand of the user, such that the inner portion of the index finger engages one of the gripping surfaces 118 and the inner portion of the middle finger engages the other gripping surface on the opposite side of the ultrasound probe. In this way, the user can lift, manipulate, slide, and otherwise move the ultrasound probe 40 with only two fingers during operation of the ultrasound imaging system 10. Note that the other fingers of the user's hand can alternatively be used to grip the ultrasound probe 40. This further enables the remaining three fingers of the user's hand to be used in other ways during ultrasound imaging with the ultrasound probe 40. These other ways include, for example, applying traction to the skin surface, touching the patient for comfort, establishing or marking physical reference points, etc.

[0117] Note that the engagement of the user's hand with the ultrasound probe 40 allows the user's hand to be positioned substantially parallel to, i.e., horizontally, the patient's skin surface during a typical imaging procedure. This, in turn, enables the user to accurately and easily move the ultrasound probe over the skin surface with relatively small movements, which results in improved imaging results. Note also that the ultrasound probe body 102 in this and other embodiments comprises a suitable material, such as a thermoplastic. In one embodiment, the material comprises R-5100 polyphenylsulfone.

[0118] Now refer to Figures 4A-4D, according to another embodiment, various details of an ultrasound probe 40 and its finger grip 110 are shown, which are configured to enable the ultrasound probe 40 to be grasped, supported, and manipulated by one or more fingers of a user's single hand, while leaving one or more fingers of the user's hand free for use in other manners described herein. As shown, the finger grip 110 includes a ring 124 defined by the body 102 of the ultrasound probe 40. In one embodiment, the ring 124 is sized to receive a user's finger, such as the index or middle finger. To this end, the inner annular surface of the ring 124 serves as a gripping surface 118 against which the user's finger rests to enable the finger to manipulate and control the movement of the ultrasound probe 40. Thus, the finger grip 110, i.e., the ring 124 in this embodiment, further serves as an example of a retaining portion to maintain engagement of the ultrasound probe 40 with the user's finger. Note that in this embodiment and other embodiments, the retaining portion keeps the ultrasound probe 40 attached to the user's fingers even when the user's fingers and / or hand are lifted from the skin surface, which enables the user to perform other tasks without putting down the ultrasound probe.

[0119] In one embodiment, the size of the ring 124 can be configured so that a user's finger can be inserted through the ring at different distances in order to encounter a fit suitable for moving and manipulating the ultrasound probe 40. Likewise, the size of the ring 124 can be one or more varying diameters. In another embodiment, an insert can be removably fitted into the ring 124 to adjust the size of the ring opening to accommodate fingers of different sizes. Note that in one embodiment, all or part of the finger grip portion can be flexible / elastic so as to deform to accommodate the user's finger. Also note that Figures 4A-4D The ultrasound probe 40 in the illustrated embodiment is approximately 2.5 inches tall, the ultrasound probe head 44 is approximately 1 inch wide, and the ring 124 is approximately 1.5 inches wide, although other dimensions are possible for this and other embodiments described herein.

[0120] Figure 17 Shown in one embodiment of use, engaging the index finger 220 of a user's hand 224. Figures 4A-4D 40. As shown, when the ultrasound probe is in an operable position on a horizontal skin surface of a patient 228, the finger grip portion 110 (i.e., the ring 124) enables the user's fingers to be positioned substantially co-linearly above and in a spaced-apart relationship relative to the lens 108 of the ultrasound probe head portion 44. This enables the user to apply a relatively fine amount of pressure or traction to the skin surface by depressing the ultrasound probe 40 on the skin surface and provides enhanced control of the ultrasound probe. Figure 17, which is an approach in which, during a typical imaging procedure, the user's hand is positioned substantially parallel to the patient's skin surface (i.e., horizontally). As described above, this enables the user to accurately and easily move the ultrasound probe with relatively small movements on the skin surface, which leads to improved imaging results.

[0121] Now refer to Figures 5A-5D According to another embodiment, various details of an ultrasound probe 40 and its finger grip 110 are depicted to enable the ultrasound probe to be grasped, supported, and manipulated with one or more fingers of a user's hand, while leaving one or more fingers of the user's hand free for other use. As shown, the finger grip 110 includes a hook 134 defined by the body 102 of the ultrasound probe 40. The hook 134 is generally C-shaped and, in one embodiment, is sized to receive a user's finger, such as an index or middle finger, while being able to open to facilitate finger insertion and removal. The inner surface of the hook 134 serves as a gripping surface 118 against which the user's finger rests to enable the finger to manipulate and control the movement of the ultrasound probe 40. Thus, the finger grip 110, i.e., the hook 134 in this embodiment, further serves as an example of a retaining portion to maintain engagement of the ultrasound probe 40 with the user's finger.

[0122] In one embodiment, the hook 134 can be sized so that different portions of a user's finger can be inserted into the hook to find a fit suitable for moving and manipulating the ultrasound probe 40. Thus, the hook 134 can be sized in one or more different sizes. In another embodiment, an insert can be removably fitted into the hook 134 to adjust its size to accommodate fingers of different sizes.

[0123] The finger grip portion 110, i.e. Figures 5A-5D The hook 134 in the embodiment of the present invention enables a user's finger to be positioned substantially co-linearly over and in a spaced relationship relative to the lens 108 of the ultrasound probe head 44. This enables the user to apply a relatively fine amount of pressure or traction to the skin surface by depressing the ultrasound probe 40 on the skin surface and provides enhanced control of the ultrasound probe.

[0124] Now refer to Figures 6A-6E, according to another embodiment, depicts various details of an ultrasound probe 40 and its finger grip 110 for enabling the ultrasound probe to be grasped, supported, and manipulated with one or more fingers of a user's single hand, while leaving one or more fingers of the user's hand free for use in other ways. As shown, the finger grip 110 includes a tab 144 extending from one of the sides 102A of the ultrasound probe body 102. The distal portion of the tab 144 includes an upwardly angled lip to provide a gripping surface 118 on which a finger of the user, such as an index finger, can be placed. Another finger, such as the middle finger of the user's same hand, can engage the opposite side 102A of the ultrasound probe body 102 to enable two fingers to manipulate and control movement of the ultrasound probe 40. Note that, as with other embodiments herein, other fingers can be used to grip the ultrasound probe 40.

[0125] Figures 6A-6E The ultrasound probe 40 of the embodiment also includes a stabilizing portion 146 that is configured to maintain the ultrasound probe in an upright, usable position on the patient's skin surface even when the user's hand is not in contact with the ultrasound probe. In this embodiment, the stabilizing portion 146 includes an angled leg 148 extending from the side surface 102A opposite the tab 144. Figure 6D The legs 148 extend downwardly (from Figure 6D 104 to provide a lower surface that is substantially flush with the lens 108 of the ultrasound probe head 44. In this way, the legs 148 stabilize the ultrasound probe 40 by providing a second contact surface for the skin in addition to the lens 108. Note that in one embodiment, the stabilizing portion 146 can also enable the ultrasound probe 40 to be manipulated by a single finger. The terminal free end of the legs 148 defines a notch 150, which, in this embodiment, is configured to removably retain a portion of the cable 104 to keep the cable 104 away from the user's hand during use of the ultrasound probe 40.

[0126] Now refer to Figures 7A-7D, according to another embodiment, depicts various details of an ultrasound probe 40 and its finger grip 110 for enabling the ultrasound probe to be grasped, supported, and manipulated with one or more fingers of a user's single hand, while leaving one or more fingers of the user's hand free for use in other ways. As shown, the finger grip 110 includes a cylindrical ring 154 extending from the body 102 of the ultrasound probe 40. In one embodiment, the cylindrical ring 154 is sized to receive a user's finger, such as the index or middle finger. To this end, the inner cylindrical surface of the ring 154 serves as a gripping surface 118 against which the user's finger rests to enable the finger to manipulate and control the movement of the ultrasound probe 40. It is noted that the finger grip 110, i.e., the cylindrical ring 154 in this embodiment, further serves as an example of a retaining portion to maintain engagement of the ultrasound probe 40 with the user's finger.

[0127] In one embodiment, the size of the cylindrical ring 154 can be configured so that a user's finger can be inserted through the ring at different distances in order to encounter a fit suitable for moving and manipulating the ultrasound probe 40. As such, the cylindrical ring 154 can be sized to one or more of different diameters. In another embodiment, an insert can be removably fitted into the cylindrical ring 154 to adjust the size of the ring opening to accommodate fingers of different sizes. In yet another embodiment, the cylindrical ring 154 can have varying diameters, such as being relatively wider at either end, in order to introduce freedom of movement for a finger inserted therein.

[0128] Figures 7A-7D The ultrasound probe 40 of the embodiment further includes a stabilizing portion 146 configured to maintain the ultrasound probe in an upright, usable position on the patient's skin surface even when the user's hand is not in contact with the ultrasound probe. In this embodiment, the stabilizing portion 146 includes the cylindrical ring 154 itself. Figure 7D The cylindrical ring 154 extends downward (from Figure 7D 108 ) to provide a lower surface that is substantially flush with the lens 108 of the ultrasound probe head 44. Thus, in addition to the lens 108, the bottom portion of the cylindrical ring 154 stabilizes the ultrasound probe 40 by providing a second contact surface for the skin.

[0129] Now refer to Figures 8A-8D , according to another embodiment, the figure depicts various details of an ultrasound probe 40 and its finger grip portion 110, which are used to enable the ultrasound probe to be grasped, supported and operated by one or more fingers of a single hand of a user, while leaving one or more fingers of the user's hand free for use in other ways.

[0130] As shown, the finger grip 110 includes a cylindrical ring 154 extending from the body 102 of the ultrasound probe 40. In one embodiment, the cylindrical ring 154 is sized to receive a user's finger, such as an index finger or a middle finger. To this end, the inner cylindrical surface of the cylindrical ring 154 serves as a gripping surface 118 against which the user's finger rests to enable the finger to handle and control the movement of the ultrasound probe 40. It is noted that the finger grip 110, i.e., the cylindrical ring 154 in this embodiment, further serves as an example of a retaining portion to maintain engagement of the ultrasound probe 40 with the user's finger.

[0131] In one embodiment, the size of the cylindrical ring 154 can be configured so that a user's finger can be inserted through the ring at different distances in order to encounter a fit suitable for moving and manipulating the ultrasound probe 40. As such, the cylindrical ring 154 can be sized to one or more of different diameters. In another embodiment, an insert can be removably fitted into the cylindrical ring 154 to adjust the size of the ring opening to accommodate fingers of different sizes.

[0132] The finger grip portion 110, i.e. Figures 8A-8D The cylindrical ring 154 in the embodiment of the present invention enables a user's finger to be positioned substantially co-linearly over and in a spaced relationship relative to the lens 108 of the ultrasound probe head 44. This enables the user to apply a relatively fine amount of pressure or traction to the skin surface by depressing the ultrasound probe 40 on the skin surface and provides enhanced control of the ultrasound probe.

[0133] Note that in this embodiment, the ultrasound probe 40 is operably connected to the console 20 ( Figure 1 ) extends from the ultrasound probe body 102 at a certain angle from the use position of the ultrasound probe (ie, from Figure 8D This cable configuration can reduce the torque of the cable 104 on the ultrasound probe 40 and keep the cable out of the user's hand. This structure can be included in other embodiments described herein.

[0134] Now refer to Figures 9A-9D , according to another embodiment, depicts various details of an ultrasound probe 40 and its finger grip portion 110 for enabling the ultrasound probe to be grasped, supported, and operated by one or more fingers of a single hand of a user, while leaving one or more fingers of the user's hand free for use in other ways.

[0135] As shown in the figure, Figures 9A-9D An embodiment similar to Figures 8A-8D , wherein a stabilizing portion 146 is added, where the tilting legs 148 are similar to Figures 6A-6E Note that the inclined legs are shown in the embodiment shown. Figures 9A-9D The specific shape of the inclined leg 148 is slightly different in shape from Figures 6A-6E The tilt leg 148 extends downward (from the top of the hand) while still being configured to maintain the ultrasound probe in an upright, usable position on the patient's skin surface even when the user's hand is not in contact with the ultrasound probe. Figure 9D The legs 148 are positioned so as to provide a lower surface that is substantially flush with the lens 108 of the ultrasound probe head 44. In this manner, the legs 148 stabilize the ultrasound probe 40 by providing a second contact surface for the skin in addition to the lens 108.

[0136] Now refer to Figures 10A-10D , according to another embodiment, depicts various details of an ultrasound probe 40 and its finger grip 110 for enabling the ultrasound probe to be grasped, supported, and manipulated with one or more fingers of a user's single hand, while leaving one or more fingers of the user's hand free for use in other ways. As shown, the finger grip 110 includes a cylindrical ring 154 extending from the body 102 of the ultrasound probe 40. In one embodiment, the cylindrical ring 154 is sized to receive a first finger of a user, such as a middle finger. To this end, the inner cylindrical surface of the ring 154 serves as a gripping surface 118 against which the user's finger rests to enable the finger to manipulate and control the movement of the ultrasound probe 40. It is noted that the finger grip 110, i.e., the cylindrical ring 154 in this embodiment, further serves as an example of a retaining portion to maintain engagement of the ultrasound probe 40 with the user's finger.

[0137] In one embodiment, the size of the cylindrical ring 154 can be configured so that a user's finger can be inserted through the ring at different distances in order to encounter a fit suitable for moving and manipulating the ultrasound probe 40. As such, the cylindrical ring 154 can be sized to one or more of different diameters. In another embodiment, an insert can be removably fitted into the cylindrical ring 154 to adjust the size of the ring opening to accommodate fingers of different sizes.

[0138] The ultrasound probe body 102 further defines a protrusion 164 and a saddle 168 to provide a second gripping surface 118 upon which a second finger of a user's hand (e.g., an index finger) can be placed to further support and manipulate the ultrasound probe 40. Thus, in this embodiment, two fingers of a single hand of a user can be used to support and use the ultrasound probe 40. The saddle 168 enables the user's fingers to be positioned substantially co-linearly over and in a spaced relationship relative to the lens 108 of the ultrasound probe head 44. This enables the user to apply a relatively fine amount of pressure or traction to the skin surface by depressing the ultrasound probe 40 thereon, and provides enhanced control of the ultrasound probe.

[0139] Figures 10A-10D The ultrasound probe 40 of the embodiment further includes a stabilizing portion 146 configured to maintain the ultrasound probe in an upright, usable position on the patient's skin surface even when the user's hand is not in contact with the ultrasound probe. In this embodiment, the stabilizing portion 146 includes the cylindrical ring 154 itself. Figure 10D The cylindrical ring 154 extends downward (from Figure 10D 108 ) to provide a lower surface that is substantially flush with the lens 108 of the ultrasound probe head 44. Thus, in addition to the lens 108, the bottom portion of the cylindrical ring 154 stabilizes the ultrasound probe 40 by providing a second contact surface for the skin.

[0140] Now refer to Figures 11A-11D , according to another embodiment, depicts various details of an ultrasound probe 40 and its finger grip portion 110 for enabling the ultrasound probe to be grasped, supported, and operated by one or more fingers of a single hand of a user, while leaving one or more fingers of the user's hand free for use in other ways.

[0141] As shown in the figure, Figures 11A-11D An embodiment similar to Figures 10A-10D , wherein the finger grip portion 110 includes a cylindrical hook 174 extending from the ultrasound probe body 102. The cylindrical hook 174 is generally C-shaped and, in one embodiment, is sized to receive a user's finger, such as an index finger or middle finger, while allowing an opening for easy insertion / removal of the finger. The inner surface of the hook 134 serves as a gripping surface 118 against which the user's finger is placed to enable the finger to handle and control the movement of the ultrasound probe 40. In one embodiment, the cylindrical hook 174 is resilient so that it can deform a limited amount to conform to the size of the user's finger and remain connected thereto. Thus, it is noted that the finger grip portion 110, i.e., the hook 134 in this embodiment, further serves as an example of a retaining portion to maintain engagement of the ultrasound probe 40 with the user's finger.

[0142] Note that in one embodiment, the cylindrical hook 174 may include an oval cross-sectional shape to further enhance its engagement with the user's finger. In one embodiment, excess material comprising the sterile cover covering the ultrasound probe 40 may be inserted into the interior portion of the cylindrical hook 174 to enhance engagement of the cylindrical hook with the user's finger (and note that this technique may be used in conjunction with other embodiments herein, including Figure 4A 、 Figure 5A 、 Figure 7A 、 Figure 8A 、 Figure 9A 、 Figure 10A and Figure 12A ). Additionally, in one embodiment, the cylindrical hook 174 may be removable to enable cylindrical rings or other finger retaining portions of different sizes / configurations to be interchanged on the ultrasound probe 40.

[0143] In addition, with Figures 10A-10D Like the cylindrical ring 154 of the illustrated embodiment, the cylindrical hook 174 of this embodiment serves as a stabilizing portion 146 configured to maintain the ultrasound probe 40 in an upright, usable position on the patient's skin surface even when the user's hand is not in contact with the ultrasound probe.

[0144] Now refer to Figures 12A-12D , according to another embodiment, depicts various details of an ultrasound probe 40 and its finger grip portion 110 for enabling the ultrasound probe to be grasped, supported, and operated by one or more fingers of a single hand of a user, while leaving one or more fingers of the user's hand free for use in other ways.

[0145] Figures 12A-12D and Figures 10A-10D Likewise, the finger grip portion 110 includes a cylindrical ring 154 , which further serves as the stabilizing portion 146 . Figures 12A-12D The illustrated embodiment includes an articulation assembly 178 disposed between the cylindrical ring 154 and the main portion of the ultrasound probe body 102. Specifically, the articulation assembly 178 includes a ball 180 included on the main portion of the ultrasound probe body 102 and a corresponding socket 182 included on the cylindrical ring, with the socket 182 being sized to receive the ball therein to enable articulated movement between the ultrasound probe head 44 and the cylindrical ring 154, through which a user's finger is received during an ultrasound imaging procedure. The articulation assembly 178 enables relative movement between the ultrasound probe head 44 and the cylindrical ring, thereby enabling free movement of the ultrasound probe 40. This is useful when it is desired to elevate the lens 108 above the skin surface while maintaining one or more fingers on the skin surface. Note that other articulation and joint structures can be employed to provide this relative movement, such as a hinge in one embodiment. Furthermore, in one embodiment, the socket configuration can be reversed.

[0146] Note that in the current and previous embodiments discussed above, the ultrasound probe head 44, lens 108, and orientation arrow 107 are configured similar to a standard ultrasound probe to provide familiarity to the user in terms of placing the ultrasound probe and lens on the skin surface and inserting the needle.

[0147] Now refer to Figures 13A-13D, according to another embodiment, depicts various details of an ultrasound probe 40 and its finger grip portion 110 for enabling the ultrasound probe to be grasped, supported, and manipulated with one or more fingers of a single hand of a user, while leaving one or more fingers of the user's hand free for use in other ways. As shown, the ultrasound probe body 102 includes a top plate 186 and a bottom plate 188 separated by the finger grip portion 110, here configured as an hourglass-shaped surface 184 defining a gripping surface 118. Two fingers of a single hand of a user, such as an index finger and a middle finger (although other fingers may be used), can straddle the hourglass-shaped surface 184 to grasp and manipulate the ultrasound probe 40. A flat side surface 190 is included on the bottom plate 188 proximate to the lens 108, which is disposed on a bottom portion of the ultrasound probe head 44, as shown. Figure 13C and 13D The cable can extend from the cable guide 194 at the top surface of the ultrasound probe body 102. As in the previous embodiments, the ultrasound probe body design shown in this embodiment enables the fingers to be positioned substantially directly above the lens 108 in a spaced-apart arrangement. Note that Figure 13B The flat bottom surface of the chassis 188, best shown in FIG. 1 , serves in this embodiment as a stabilizing portion for enabling the ultrasound probe 40 to be placed on the patient's skin surface without assistance.

[0148] Figure 14 An ultrasound probe 40 according to one embodiment is depicted. Here, the ultrasound probe 40 is similar to Figures 13A-13D , but the flat side surface 190 near the lens 108 is relatively large.

[0149] Figure 15A and 15B Depicts Figures 13A-13D , in which the chassis of the ultrasound probe body 102 is omitted and two chamfered surfaces 200 are defined on the bottom of the ultrasound probe body proximate the lens 108. Accordingly, these and other variations of the ultrasound probe body 102 are contemplated while still enabling the ultrasound probe 40 to be grasped and manipulated with one or more fingers, while still enabling other fingers of the user's hand to be free for other purposes.

[0150] According to another embodiment, Figures 16A-16D Various details of the ultrasound probe 40 and its finger grip 110 are depicted for enabling the ultrasound probe to be grasped, supported, and operated by one or more fingers of a single hand of a user, while leaving one or more fingers of the user's hand free for use in other ways. Figure 16C and 16DAs shown, the ultrasound probe body 102 includes a generally wedge-shaped configuration with the lens 108 of the ultrasound probe head 44 disposed on its bottom surface. Figure 16B The flat bottom surface of the ultrasound probe body 102, best shown in FIG. 1 , serves in this embodiment as a stabilizing portion for enabling the ultrasound probe 40 to be placed on the patient's skin surface without assistance.

[0151] The cable guide 194 extends from the ultrasound probe body 102 and includes two finger grips 110, i.e., two channels 210 defined by the body and disposed adjacent the cable guide to provide two concave gripping surfaces 118. Two fingers of a single hand of a user, such as the index and middle fingers, can be received in the channels 210 to support and manipulate the ultrasound probe 40, while freeing the other fingers of the user's hand for other purposes. Accordingly, these and other ultrasound probe body shapes and finger grip configurations are contemplated.

[0152] Note that the ultrasound probe discussed herein is also configured so that a sterile cover can be placed on it and an elastic band is used to secure the cover to the ultrasound probe. The ultrasound probe herein is also configured to be symmetrical along at least one midline axis so as to be capable of left-handed and right-handed use.

[0153] In one embodiment, it will be appreciated that icons / symbols may be placed on the ultrasound probe body 102 to help the user know where to place their fingers to use the ultrasound probe 40 .

[0154] Figures 18A-18G Various views of an ultrasound probe 40 are provided according to some embodiments. Figure 19 A perspective view of an ultrasound probe 40 is provided, according to some embodiments. Figure 19 The ultrasound probe 40 shares the following description Figures 18A-18G Features of the ultrasound probe 40; however, Figure 19 The ultrasound probe 40 includes an additional feature, namely a catheter-tube extension.

[0155] As shown, the ultrasound probe 40 includes a body 102, a lens 108, a stabilizing portion 146 of the body 102, and a finger grip portion 110 of the body 102. Figures 18C-18F As best shown in , the ultrasound probe 40 is bilaterally symmetrical about a plane of symmetry of the ultrasound probe 40 .

[0156] The body 102 of the ultrasound probe 40 may be formed from a molded thermoplastic such as polyphenylsulfone. Figure 18C At least the top portion of the illustrated body 102 may be formed from molded thermoplastic halves coupled together along a plane of symmetry of the ultrasound probe 40 . Figure 18DThe bottom portion of the body 102 shown in FIG can be formed of a molded thermoplastic material coupled to the top portion of the body 102. The bottom portion of the body 102 can include a cutout or molded latitudinal hole configured to hold the lens 108.

[0157] The head portion 44 of the ultrasound probe 40 is defined by at least a lens 108 disposed in a cutout or molded latitudinal hole in the body 102. The lens 108 is configured to pass ultrasound signals therethrough. The ultrasound signals include transmitted ultrasound signals emitted by the piezoelectric transducer array within the ultrasound probe 40 behind the lens 108. The ultrasound signals also include reflected ultrasound signals, such as those reflected from the tissue being imaged into the ultrasound probe 40.

[0158] The stabilizing portion 146 of the ultrasound probe 40 consists of a longitudinally extending portion of the body 102 extending away from the head portion 44 of the ultrasound probe 40. The stabilizing portion 146 is configured to stabilize the ultrasound probe 40 on the patient's skin surface without assistance from a user of the ultrasound probe 40.

[0159] The stabilizing portion 146 of the ultrasound probe 40 includes transverse channels 147 extending from one longitudinal side of the ultrasound probe 40 to the other. The transverse channels 147 reduce the surface area of ​​the generally flat surface of the stabilizing portion 146, which is intended to face the patient's skin surface. The reduced surface area of ​​the stabilizing portion 146 facilitates movement of the ultrasound probe 40 over the patient's skin surface by reducing the contact area between the surface of the stabilizing portion 146 and the patient's skin surface. The reduced surface area of ​​the stabilizing portion 146 also reduces the suction force between the surface of the stabilizing portion 146 and the patient's skin surface when gel is present between the surfaces of the stabilizing portion 146 and the patient's skin surface and the ultrasound probe 40 is removed from the patient. Furthermore, the transverse channels 147 provide a space between the ultrasound probe 40 or the stabilizing portion 146 and the patient's skin surface, into which a finger can be inserted to lift the ultrasound probe 40 from the patient's skin surface when removing the ultrasound probe 40 from the patient's skin surface.

[0160] The finger grip portion 110 of the ultrasound probe 40 is comprised of a generally lateral extension of the body 102 that extends away from the head portion 44 of the ultrasound probe 40. The finger grip portion 110 is configured to enable a user to grasp and manipulate the ultrasound probe 40 with no more than two or three fingers of a single hand during use of the ultrasound probe 40. For example, the two fingers may be the thumb and index finger. The finger grip portion 110 of the ultrasound probe includes a concave gripping surface 118 that opposes a generally flat surface. The gripping surface 118 is an extension of the concave surface of the stabilizing portion 146 of the ultrasound probe 40 that is intended to face away from the patient's skin surface. In other words, the concave surface of the stabilizing portion 146 opposes the generally flat surface of the stabilizing portion 146 that is intended to face toward the patient's skin surface.

[0161] The ultrasound probe 40 includes a cable guide 194 formed by a curved extension of the body 102 of the ultrasound probe 40 that extends away from the stabilizing portion and the head portion of the ultrasound probe 40. The cable guide 194 is configured to accommodate distal end portions of power and data cables, such as the cable 104 used to connect the ultrasound probe 40 to the console 20. The cable guide 194 is also configured to keep the power and data cables away from the head portion 44 of the ultrasound probe 40, thereby reducing interference with the power and data cables when the ultrasound probe 40 is in use. Figure 19 As shown in FIG, the cable guide 194 may include an extension 196 on a side of the cable guide 194 that is intended to face the patient. The extension 196 is configured to reinforce the cable jacket 195 described below while keeping power and data cables away from the head portion 44.

[0162] The ultrasound probe 40 includes a cable guard 195 having a distal end portion disposed within the opening of the cable guide 194. The cable guard 195 is configured to accommodate the distal end portion of the power and data cable at the proximal end of the cable guide 194. The cable guard 195 is also configured to keep the power and data cable away from the head portion 44 of the ultrasound probe 40. The cable guard 195 is also configured to attenuate the bend radius of the power and data cable around the opening of the cable guide 194. Attenuating the bend radius of the power and data cable reduces the risk of damage to the power and data cable at the opening of the cable guide 194, where the power and data cable is most likely to be excessively bent by moving the ultrasound probe 40 when the ultrasound probe 40 is in use.

[0163] Figure 20A and 20B 、 Figure 21A and 21B 、 Figure 22A and 22B 、 Figure 23A and 23B Various views of different ultrasound probes according to some embodiments are provided.

[0164] As shown in the figure, each ultrasound probe 40 includes a body 102, a head portion 44 of the body 102, and a finger grip portion 110 of the body 102. Each ultrasound probe 40 is bilaterally symmetrical about a symmetry plane of the ultrasound probe 40.

[0165] The body 102 of each ultrasound probe 40 may be formed from a molded thermoplastic, such as polyphenylsulfone.

[0166] The head portion 44 of each ultrasound probe 40 is designated by at least one lens 108 disposed in a cutout or molded hole in the body 102. The lens 108 is configured to pass transmitted and reflected ultrasound signals therethrough.

[0167] The finger grip 110 of each ultrasound probe 40 is formed from a thimble-type structure of the body 102 of the ultrasound probe 40. The finger grip 110 is configured to enable a user to insert, for example, an index finger or a middle finger therein for manipulating the ultrasound probe 40 during use of the ultrasound probe 40. The finger grip 110 includes the gripping surface 118 as described above.

[0168] At least Figure 23A and Figure 23B The ultrasound probe 40 is shown with a cable guide 194 configured to receive a distal end portion of a power and data cable (such as cable 104) for connecting the ultrasound probe 40 to the console 20. Figure 23A and 23B ) shows a cable guide 194, but it should be understood that Figure 20A and 20B 、 Figure 21A and 21B as well as Figure 22A and 22B Any ultrasound probe in the range may include such a cable guide.

[0169] method

[0170] The method of obtaining the ultrasound probe 40 includes an obtaining step of obtaining the ultrasound probe 40. For example, the obtaining step may include obtaining Figures 18A-18G The ultrasound probe 40 includes a body 102, a stabilizing portion 146 of the body 102, and a finger grip portion 110 of the body 102. Similarly, the body 102 of the ultrasound probe 40 described above has a lens 108 disposed in a cutout or molded latitudinal hole in the body 102, which designates the head portion 44 of the ultrasound probe 40. The stabilizing portion 146 is comprised of a longitudinally extending portion of the body 102 that extends away from the head portion 44 of the ultrasound probe 40. The finger grip portion 110 is comprised of a generally transversely extending portion of the body 102 that extends away from the head portion 44 of the ultrasound probe 40.

[0171] The method also includes the step of connecting the power and data cables of the ultrasound probe 40 to the console 20 of the ultrasound imaging system 10. The cables 104 extend from a cable guide 194 and a cable jacket 195 of the ultrasound probe 40. Likewise, the cable guide 194 and the cable jacket 195 are configured to keep the power and data cables away from the head portion 44 of the ultrasound probe 40 when the ultrasound probe 40 is in use.

[0172] The method may include an applying step of applying ultrasound gel to the patient's skin surface prior to placing the ultrasound probe 40 on the patient's skin surface.

[0173] The method also includes a grasping step of grasping the ultrasound probe 40. The grasping step includes placing at least one of the index finger or the middle finger on the concave grasping surface 118 of the finger grip portion 110 of the ultrasound probe 40 and placing the thumb on the opposite generally flat surface of the finger grip portion 110. The grasping step orients the palm of the hand to which the aforementioned fingers belong substantially parallel to the skin surface of the patient.

[0174] The method further includes a placing step of placing the head portion and the stabilizing portion of the ultrasound probe 40 on the skin surface of the patient.

[0175] The method further includes an enabling step of enabling the detection ultrasound signal to be transmitted from the piezoelectric transducer array within the ultrasound probe 40 into the patient's body for ultrasound imaging. The method further includes another enabling step of enabling the reflected ultrasound signal to be reflected from the patient to the piezoelectric transducer array within the ultrasound probe 40 so as to be converted into an electrical signal for a corresponding ultrasound image. The enabling step may include turning on the console 20, selecting one or more imaging modes of the ultrasound imaging system 10, or starting ultrasound imaging with the ultrasound probe 40 by activating a start button on the console 20.

[0176] The method further includes a moving step of moving the ultrasound probe 40 using no more than the aforementioned two or three fingers of a single hand to perform ultrasound imaging through the finger grip portion 110 of the ultrasound probe 40. The moving step does not cause the power and data cables to bend excessively due to the cable jacket 195 attenuating the bending radius of the power and data cables.

[0177] The method also includes a removal step of removing the ultrasound probe 40 from the patient's skin surface. Similarly, the stabilizing portion 146 of the ultrasound probe 40 includes transverse channels 147 extending from one longitudinal side of the ultrasound probe 40 to the other. The transverse channels 147 reduce the surface area of ​​the substantially flat surface of the stabilizing portion 146, thereby reducing the gel-induced suction force between the surface of the stabilizing portion 146 and the patient's skin surface during the removal step. Furthermore, the transverse channels 147 provide a space between the ultrasound probe 40 and the patient's skin surface, such that, for example, an index finger can be inserted into the space to lift the ultrasound probe 40 when removing the ultrasound probe 40 from the patient's skin surface.
