Definitions
- a guide pin is often used and devices such as Sluss US2011/0087250 are designed with a secondary lumen to slide over the guide pin and subsequently cut tissue but this presents the logistical issue of multiple exchanges, which adds time and complexity to the procedure.
- Other devices such as McCormack U.S. Pat. No. 8,753,364 are specifically designed to cut ligaments (e.g. carpal ligament) in a minimally invasive fashion using a serrated saw-type instrument, but do not allow for direct penetration of the skin and underlying tissue via an integral needle
- Embodiments proposed herein solve the above issues by providing a minimally invasive tissue incision system (referred to at points herein as a “needle-knife”) having a tissue cutting mechanism within a penetrating needle.
- the penetrating needle is used to initiate a procedure.
- a capsulotomy may be created without the need for withdrawing the needle, thus reducing the risk associated with bladed instrument exchanges.
- a fibrous tissue band In release-type procedures, a fibrous tissue band generally requires incising in order to restore some functionality. While sometimes performed arthroscopically (with a camera), these procedures are also performed with the use of ultrasound guidance. Ultrasound guidance provides the advantage of not requiring a camera (and associated cannula) to be inserted into the working space since the ultrasound probe resides outside the patient. In these procedures, ultrasound is used to visualize the needle penetration to the desired location. A cutting or debriding tool may then directly placed or inserted via the needle lumen to incise the fibrous tissue band. In accordance with embodiments described herein, the proposed needle-knife facilitates such procedures by providing the cutting element within the confines of the needle, which provides safe introduction of the cutting element directly to the site via the needle.
- the minimally invasive tissue incision system in accordance with embodiments herein may be used as a penetrating needle to pierce the skin and other soft tissue structures.
- a cutting mechanism is provided within the penetrating needle which may be used to incise subsequent tissue structures after the initial penetration.
- the cutting element may be disposed at the end of a stylet coaxially disposed within the lumen of the needle.
- the cutting element/stylet is slideable within the needle and may be completely removable from the primary needle assembly so as to allow other instruments or fluids to be passed down the lumen of the needle.
- a luer fitting is preferably situated at the proximal end of the device to facilitate connection of the stylet and/or ancillary devices.
- the penetrating needle being coaxially slideable about the stylet/cutting element, may be configured with a slider so as to facilitate retraction of the needle relative to the stylet/cutting element.
- the needle may be further configured with a spring mechanism so as to facilitate the needle's retraction relative to the stylet/cutting element.
- the stylet may be configured such that the distal most portion occludes the distal lumen of the needle so as to prevent tissue or other debris from becoming lodged within the needle lumen.
- the cutting element is situated just proximal of the occluding portion, which is preferably a relatively thin section, like a plate.
- the penetrating needle may have a window situated just proximal to the distal needle tip.
- a second, inner tubular structure with a window opposite that of the window on the needle.
- the stylet/cutting element resides within the inner tubular structure.
- the inner tubular structure may be configured with a rotator knob at the proximal end so as to facilitate rotation of the tube to align the windows and expose the cutting element.
- the proximal end of the device may be configured as a slender hub, similar to that of a typical spinal needle. This configuration facilitates fingertip control.
- the proximal end of the device may be configured into a larger handle, meant to be grasped or gripped in the palm of the hand.
- a method of performing a joint capsulotomy involves the acts of: 1.) inserting the needle-knife into the joint space; 2.) retracting the needle component of the needle-knife a specified distance so as to expose a cutting element; and 3.) completing the capsulotomy with the cutting element of the needle-knife. Further acts of the method may include: 4.) removing the stylet/cutting element from the needle-knife and inserting a guide wire/pin through the lumen of the needle to facilitate insertion of other instrumentation.
- methods for performing various “release” procedures involve the acts of: 1.) percutaneous insertion of the needle-knife into the region containing fibrous band to be released; 2.) retracting the needle component to expose the cutting blade; 3.) using the exposed blade to incise the fibrous band thus providing “release;” and 4.) extending the needle (reverse of act 2) to cover or sheath the cutting blade and removing the assemble from the tissue.

- FIG. 1 is a perspective view a needle-knife device 100 with a cutting member 102 ( FIG. 3 ) sheathed within a penetrating needle 104 .
- This position represents an initial state in which the device 100 would be manipulated to penetrate the needle 104 through animal or human skin and into underlying tissue.
- the penetrating needle 104 is shown fixedly attached at the proximal end to a slider 106 which is linearly slideable within a housing 108 .
- the slider 106 may be rotationally slideable as well, so as to lock into a secondary slot(s) (not shown in FIG.
- the user grips the needle-knife device 100 at the housing 108 and penetrates the skin and underlying tissue with the distal tip 112 of the needle 104 .
- the user activates the slider 106 by moving the slider to a more proximal position, thus retracting the needle 104 relative a cutting element 102 (best shown in FIG. 3 ) so as to expose the cutting element.
- the user manipulates the device as necessary so that the cutting element can cut tissue structures as desired.
- FIG. 2 shows the needle-knife device 100 with the needle 104 in a retracted state.
- the cutting element 102 is exposed from the distal tip 112 of the needle.
- the slider 106 is in the fully retracted position.
- a detent mechanism may be employed between the slider and the housing 108 so as to allow selective partial retraction of the needle 104 .
- friction can be provided between the components to allow for infinite selective retraction.
- the cutting member 102 is disposed at the end of a stylet 114 (shown in FIG. 3 ).
- the stylet 114 can be composed of a rod, tube, or other shaped elongated member which is attached to a hub 116 at the proximal end.
- the stylet 114 is mounted in the housing 108 (shown in FIG. 3 ). With the cutting member exposed, tissue or structures may be incised by manipulating the device.
- the stylet 114 is shown completely removed from the housing 108 .
- a hub 116 is shown fixedly attached.
- This hub 116 contains features which allows the hub to be removably attached to the housing 108 .
- the hub 116 utilizes an internal thread with a male luer 118 .
- This male luer mates to a boss 120 on the housing 108 containing a female luer and external threads 122 .
- Other attachment means may be employed such as snaps, however the use of standard luer fittings has the added benefit of allowing the attachment of syringes and other medical apparatus for other purposes.
- the stylet remains attached to the housing during normal operation.
- an internal seal such as an o-ring may be used to create a fluid-tight seal between the internal surface of the housing 108 and the external surface of the needle 104 in order to prevent injectable fluids like drugs from escaping the device.
- the hub 116 may be configured on its proximal end to accept an electrosurgical connector. This would give the distal end of the stylet/cutting element capability to cut, coagulate, seal, desiccate, or fulgurate tissue with the use of an electrosurgical generator. Further details are provided in embodiments described later in this application.
- FIG. 4 shows another embodiment of a needle-knife device 200 which utilizes a window 222 in a penetrating needle 204 situated just proximal to the distal needle tip 212 .
- a rotator knob 206 attached to the proximal end of the penetrating needle 204 and rides within a circumferential slot 210 in the housing 208 and facilitates rotation of the needle to align the window opening 222 with the cutting element 202 (shown in FIG. 5 ) so as to expose the cutting element.
- This view shows the window in the “closed” position, wherein the back side (opposite the cutting element) of the stylet obscures the window opening 222 .
- the stylet of this embodiment is designed such that its outer diameter is very close to the inner diameter of the needle, creating a flush closure of the needle window.
- a twist knob attached to the needle 204 and axially aligned and rotatably connected to the housing may facilitate rotation of the needle.
- the stylet 214 may be rotatable within the needle 204 .
- another inner tube situated coaxially and rotatably within the needle and having its own window may be utilized to cover and expose the underlying cutting element.
- FIG. 5 is a close up view of the distal end of the window needle-knife device of FIG. 4 .
- Coaxially and rotatably situated within the penetrating needle 204 is a stylet 214 with cutting element 202 .
- the needle is shown rotated 180 degrees from its position in FIG. 4 , which aligns the window 222 to expose the underlying cutting element 202 .
- the stylet 214 can be rotated so that the cutting element 202 is exposed through the window 222 or not. With the underlying cutting element 202 exposed, tissue may be incised as in the other embodiments via manipulation of the entire assembly.
- the cutting element 102 and/or 202 may generally be any sharp blade configuration, and can be straight, curved, angled and/or serrated.
- the cutting element 202 extends orthogonally from the axis of the stylet 214 .
- FIG. 6 shows an embodiment of the cutting element 102 as used with the needle-knife embodiment of FIGS. 1-3 .
- This cutting element is similar to a sharp pointed scalpel blade.
- the primary cutting edge 103 of the blade is positioned orthogonally to the axis of the stylet 114 .
- the sharp point 105 may provide added utility in piercing tissue structures.
- Multiple cutting elements may be positioned side-by-side in the orientation shown here to provide additional cutting capability.
- the cutting elements may be powered from an internal or external source so as to alternately reciprocate, thus providing enhanced cutting capability in certain media.
- the cutting element(s) may be a separate component(s) that is affixed to the stylet or the cutting element and the stylet may be fabricated from a single piece of steel or other suitable material. All cutting elements disclosed herein may be utilized with either the open end needle-knife embodiments (e.g., FIG. 3 ) or the window needle-knife embodiments (e.g., FIG. 5 ).
- FIG. 7 shows another embodiment of a cutting element 302 with a rounded tip 304 .
- the cutting edge of the member is continued around the tip to create at least a partial cutting edge 305 on the back side of the blade. This may provide the added utility of cutting in the opposite direction without having to rotate the device 180 degrees. It is understood that a sharp tip may be combined with a double-edged cutting element just as a rounded tip may have only one sharp cutting surface.
- FIG. 8 shows another embodiment of a cutting element 303 with a cruciform blade configuration.
- This configuration has a flat blade 306 with a second flat blade 307 crossing it in the center at 90 degrees.
- This type of blade arrangement may provide advantages for penetrating a tissue structure.
- FIGS. 6-8 show cutting elements that do not occlude the lumen of the penetrating needle.
- FIG. 9 is an embodiment of a cutting element 310 that has a flat surface 314 at the distal end of the cutting element 312 .
- This flat surface 314 is shaped and angled so as to match the bevel of the outer needle.
- multiple cutting elements, such as the cutting element 312 may be arranged side-by-side behind the flat surface 314 so as to make multiple incisions simultaneously in tissue.
- the surface 314 which occludes the lumen of the penetrating needle is flat, however in other embodiments the surface may take other shapes, such as rounded, bullet-shaped or pointed.
- a needle-knife device 500 which may be used to create a capsulotomy in joint tissue.

- the penetrating needle 502 of the needle-knife device 500 is shown penetrating through the skin layer 406 , the other soft tissue 408 , and into the joint capsule 404 such that the distal needle tip 503 is positioned just inside the joint capsule 404 .
- the slider 504 on the device 500 is in its distal most position. In use, appropriate positioning of the needle in the joint space would be confirmed at this point by the user with endoscopic visualization or fluoroscopy or some other visualization system.
- FIG. 11 shows a further step in the capsulotomy sequence of the same joint space as FIG. 10 .
- the penetrating needle 502 may be refracted by moving the slider 504 toward the proximal end of the handle.
- the cutting element 506 is exposed, residing in the same position in the joint that the needle tip 503 previously resided.
- the device may be manipulated so as to force the cutting element laterally to cut joint capsule tissue, thereby enlarging the incision in the capsule and creating space for the placement and maneuvering of subsequent instruments.
- the slider may be advanced distally to its original position, thus resheathing the cutting element for atraumatic withdrawal.
- FIGS. 10 and 11 are intended as generic representations of a typical joint structure and may represent the shoulder joint, elbow, knee, or hip joints. Other joint structures such as the spine may also benefit from the similar use of the needle-knife device disclosed herein.
- FIGS. 12 and 13 are simplified generic representations of a body structure shown in cross section.
- This body structure could represent a hand or foot, leg or arm.
- the body structure has fibrous band or ligament 604 (shown in section) running through it below the skin level at 602 .
- These figures show how a needle-knife device substantially the same as disclosed herein may be used to incise a fibrous band or ligament structure for medical purposes as may be done in “release” or other procedures. Typical procedures of this type include, but are not limited to plantar fascia release, carpal tunnel release, Achilles lengthening, illeotibial band release and compartment release.
- FIG. 12 shows the penetrating needle 606 of said needle-knife device having been penetrated into the anatomical space surrounding a fibrous band or ligament 604 .
- the needle 606 may be placed across the breadth of the band/ligament 604 such that the tip 607 is positioned under the distal side of the band/ligament 604 .
- the needle 606 may then be retracted a specified distance as described previously, thus exposing the cutting element 608 as shown in FIG. 13 .
- the band ligament is incised.
- a single incision with the cutting member may be sufficient, or depending upon the surgical procedure, multiple passes of the cutting member may be required to sufficiently incise the tissue. Any of the embodiments of the invention disclosed herein may be used for this type of medical procedure.
- Surgical applications discussed thus far have been generally orthopedic in nature, however the scope of use of embodiments herein is not limited to only to orthopedics. Any surgical procedure requiring incision or modification of an internal tissue structure may benefit from the use of the needle knife device.
- the needle-knife device can be particularly useful in minimally invasive procedures where a secondary visualization source (e.g. scope camera, x-ray, or ultrasound) is used. Examples of other procedures may include, but are not limited to, cardiac surgery, neurosurgery, gynecological, gastrointestinal or general laparoscopic surgery. Variations on the embodiments disclosed herein may enhance the usefulness for specific surgical applications.
- the typical length of the needle of the embodiments disclosed herein for arthroscopic procedures might be in the range of 0.5 to 5 inches (except for hip arthroscopy which is about 8 inches).
- a significantly longer needle may be useful (6-14 inches) in order to reach the surgical site.
- variations of the embodiments disclosed herein may enhance visualization of the device.
- certain surface modifications, treatments, or coatings may be applied to the needle, blade and/or stylet to enhance their visibility when used with ultrasound guidance.
- Such treatments may include but are not limited to dimpling, blasting and coating so as to alter the component's interaction with the ultrasound waves, making it more readily visible.
- FIG. 1 Up to this point embodiments disclosed herein have focused on a cutting stylet within the needle structure.
- FIG. 1 Further embodiments include a stylet configured at the distal end to perform functions other than cutting, as with a sharp blade. Such functions may include but are not limited to scraping, gouging, debriding, fenestrating, roughening, skiving, filing, or sanding. Said functions may generally be employed in an effort to remodel the tissue for clinical benefit.
- the stylet of the present invention may be configured to perform any one or more of these tasks, and may further be removable as previously disclosed.
- FIG. 14 shows an embodiment similar in structure to prior embodiments with a penetrating needle 104 and removable stylet 702 .
- the distal tip of the stylet 702 is a conical shape and has a roughened surface.
- FIG. 15 shows a similar configuration, but the stylet has a knurled surface 703 .
- the stylets 702 and 703 with the roughened surfaces can be used for debriding of bone or other hard tissue so as to remodel the tissue structure.
- the conical roughened tip may reside behind the cutting edge of the needle during needle penetration, then exposed as the needle is retracted in preparation for tissue remodeling.
- the stylet/assembly may then be rotated or reciprocated so as to remodel the tissue. While the distal portion of the stylet of these embodiments is shown in a conical, tapered configuration, other embodiments have a straight, non-tapered tip or a reverse-tapered tip.
- FIG. 16 shows a similar embodiment wherein the distal stylet tip is spherical in shape and contains cuts 704 , such as indentations or grooves, in a spiral formation about the spherical stylet tip.
- the stylet may be rotated either manually or by a powered source so as to remove small amounts of surface tissue (i.e., via the cuts 704 ) in an effort to remodel the tissue.
- a stylet may also be composed of a tubular member 706 with an open end 707 as shown in FIG. 17 .
- a stylet may be used to gouge or scrape bone or other hard tissue so as to remodel the tissue.
- a suction source may be attached at the proximal end and suction applied through the tube to remove small pieces of loose tissue debris as it is released from the main body of tissue.
- openings 708 in the sidewall of the tubular stylet may allow for debriding or scraping of bone or tissue at an alternate angle of approach.
- FIG. 18 shows an embodiment of a device with such a blunt, rounded stylet tip 710 .
- the rounded stylet tip may reside beyond the distal tip 112 of the penetrating needle 104 so as to provide blunt dissection only.
- the rounded tip stylet 712 may be removed and replaced with other stylets as disclosed herein to perform alternate functions as the procedure or the patient anatomy may demand.
- FIG. 19 shows an embodiment of the device with a stylet 714 that is configured as a drill bit.
- the drill bit portion of the stylet is exposed beyond the distal tip 112 of the needle and a hole may be drilled in the tissue by rotating the stylet from the proximal end.
- the stylet may be rotated manually or attached to a powered driver source.
- FIG. 20 shows another embodiment wherein the distal stylet tip 716 has flat sides.
- the flat sides have a knurled or roughened surface 718 that can be used to remodel the tissue as necessary for the clinical situation.
- the distal tip 716 may have one or multiple flat surfaces.
- FIG. 21 is an embodiment of a needle-knife device 800 with a smaller housing 804 at the proximal end that is designed to be held and manipulated with the fingertips.
- a penetrating needle 802 is present and shown in the extended position with a bladed stylet disposed inside the needle lumen.
- the stylet is fixedly attached at the proximal end to a hub 806 .
- the stylet/hub assembly is removable and replaceable with other stylets of similar form and in a manner as disclosed in prior embodiments.
- the penetrating needle 802 is fixedly attached to a shuttle 808 ( FIG. 22 ).
- This shuttle 808 is slidably disposed within the housing 804 so as to move the penetrating needle in the axial directions.
- the shuttle 808 of this embodiment has a distal tip 810 and a proximal tip 812 ( FIG. 23 ).
- a compression spring 803 is utilized to retract the penetrating needle 802 and expose the cutting blade or other structure at the distal end of the stylet. The intent is to provide needle retraction with a very limited finger movement, as in pushing a button with a fingertip.
- the shuttle 808 In a latched position, the shuttle 808 is pressed distally, against the bias of the spring 803 , until a back edge 818 of the distal shuttle end 810 latches behind a front edge 816 of the housing 804 .
- the internal compression spring 803 applies a force in the proximal direction against the shuttle 808 so that when the distal tip 810 of the shuttle is pushed inward toward the needle by a technician's finger, the shuttle “unlatches” and is free to move proximally under the force of the compression spring.
- FIG. 22 shows the same device 800 with the penetrating needle 802 in the retracted state so as to expose a cutting blade 814 .
- the proximal tip 812 of the shuttle 808 is shown in displaced position as forced there by the compression spring.
- the compression spring 803 is shown within the housing at full extension and pushing the shuttle 808 to its proximal position.
- the penetrating needle 802 is shown fixedly attached to the shuttle 808 , such that movement of the shuttle in the axial direction produces retraction and extension of the needle 802 relative to the stylet with cutting blade 814 .
- the proximal end of the stylet with cutting blade 814 is fixedly attached to the hub 806 .
- the shuttle 808 with attached penetrating needle 802 moves axially forward within the housing 804 and compresses the spring 803 until a back edge 818 of a distal tip 810 of the shuttle catches on the front edge 816 of an opening 820 in the housing 804 .
- the spring 803 is compressed and the penetrating needle 802 is extended forward so as to cover the cutting blade, putting the mechanism into a “cocked” state.
- the distal tip 810 of the shuttle 808 When the operator wishes to retract the needle 802 to expose the cutting blade, the distal tip 810 of the shuttle 808 is pressed inward toward the needle, thus dissociating the back edge 818 of the shuttle from the front edge 816 of the opening 820 in the housing 804 .
- This allows the spring force to push the shuttle 808 and associated needle 802 proximally to uncover the cutting blade.
- a front edge 805 of the proximal shuttle end 812 catches on a back edge 807 of the housing 804 preventing forward movement of the needle. This may be of particular use when friction created by skin and other tissue around the needle is great enough so as dislodge the needle inadvertently.
- FIG. 24 is another embodiment wherein the penetrating needle 830 contains a lumen-occluding element 832 shown in partially hidden lines.
- the inclusion of a lumen-occluding element in the device may be necessary to prevent tissue from entering the lumen of the needle 830 upon penetration through the tissue.
- the lumen-occluding element 832 may have a slot 834 which allows extension of a cutting blade when the cutting needle 830 is retracted.
- the slot 834 may be rectangular, square, round, or any other shape that may be required to allow for passage of a cutting blade or other tissue-remodeling element.
- the lumen-occluding element is generally fixedly attached to the penetrating needle and may be very short like a wafer or may extend a significant distance down the lumen of the needle to the extent that it may extend the full length of the penetrating needle.
- the lumen-occluding element may be preferably manufactured from plastics or metals commonly used in medical devices. Other materials such as ceramics or foams may also be suitable.
- a lumen-occluding element may also be integrated with the stylet/or cutting blade.
- FIGS. 25 and 26 illustrate such an embodiment.
- the lumen-occluding element 840 is integrated with the stylet/cutting blade 842 and is shown in hidden lines within the lumen of the penetrating needle 844 .
- FIG. 26 shows the penetrating needle 844 retracted to expose the cutting blade 842 with a lumen-occluding element 840 at the distal tip.
- the lumen-occluding element 840 is a disc-shaped element.
- the lumen-occluding element may be any shape which partially or substantially occludes the lumen of the penetrating needle such as spherical or multi-faceted shapes such as rectangular or hexagonal.
- the lumen-occluding element is preferably manufactured from metals or plastics commonly used for medical devices. It may be formed integrally with the cutting blade from the same piece of raw material or may be fabricated separately and attached to the cutting blade via a friction fit, adhesive, snap fit, welding or other assembly mechanism.
- FIGS. 27-29 show an embodiment of the present invention substantially the same as the embodiments of FIGS. 1-3 , but refined for ease-of-use and manufacturability. Contours on the underside of the handle provide a place for the user's fingers to grip and strategically placed ridges 906 provide better traction for the user to manipulate the device.
- the slider 902 which manipulates the needle 908 is shown in the forward position thus covering the cutting blade 910 .
- a locking feature which helps to prevent needle retraction when penetrating the skin or other tissues.
- a locking feature to prevent needle movement may take many forms.
- FIG. 27 Shown here is a bayonet-style lock, wherein the slider 902 , when advanced fully forward, is secondarily moved to the side (in an axial fashion) and into a slot which prevents backwards movement and subsequent retraction of the needle.
- the slider 902 is shown in the locked position and thus rests off-center from the rest of the handle.
- FIG. 28 shows a front view of the device in the locked mode, where the slider 902 can be clearly seen in a position offset from the center of the handle. In use, the operator would manually move the slider 902 back to the center position and thus out of the locking slot prior to retracting the slider to subsequently retract the needle and expose the cutting blade.
- FIG. 29 shows a partial cut-away view of the needle knife device with a locking mechanism.
- the slider and needle are shown in the “unlocked” and retracted position.
- a biasing member 912 is shown which is designed to facilitate movement the slider 902 sideways into a locking slot as the use user pushes the slider forward to extend the needle 908 over the cutting blade 910 .
- the biasing member may be a separate component that is attached to the handle or may be manufactured as parts of the handle itself.
- no biasing mechanism may be present, thus requiring the user to manually push the slider 902 into the bayonet slot.
- proximal movement of the needle and slider such as a button-like protrusion on the slider which protrudes through a hole or slot in the handle and must be actively disengaged by the user in order to allow movement of the slider and needle.
- a button-like protrusion on the slider which protrudes through a hole or slot in the handle and must be actively disengaged by the user in order to allow movement of the slider and needle.
- Another example of such a mechanism would be a pull tab or break-away tab which provides a physical block preventing the slider from moving proximally and may be manually removed by the operator.
- Such locking mechanisms are designed with sufficient strength so as to prevent proximal needle movement when piercing the skin or other soft tissues.
- FIG. 30 shows an embodiment of the needle knife device configured for use with an RF generator 930 .
- the needle knife device is configured with one or more standard RF receptacles (male or female) for connection to the RF generator 930 .
- the plug is internally connected to the blade/stylet through the cap 934 such that electrical energy may be delivered to the cutting blade or other functional instrument at the end of the stylet.
- the use of electrical current with the device may require additional features for effectiveness such as insulation along the length of the stylet or needle so as to prevent dispersion of the current to surrounding tissues and concentrate it at the un-insulated distal tip. Any other design aspects typically found in electrosurgical instruments which enhance safety or effectiveness may be applied to the needle knife device in a similar manner.
- Other examples of energy that may be applied through the needle knife device include, but are not limited to, ultrasonic vibration and thermal energy.
- the invention disclosed herein may be configured to work with nerve monitoring equipment. Certain procedures may be carried out in the vicinity of critical neurological structures (e.g. the ulnar nerve in the wrist/hand) making it important know the location of the tip of the needle knife device with respect to such a structure.
