Definitions
- This invention relates to cutting instruments, and more particularly, to a surgical cutting instrument for cutting tough fibrous tissue.
- Tough fibrous tissues such as intrauterine fibroids and meniscal cartilage are difficult to resect with current arthroscopic instruments such as shaver blades.
- Conventional shaver blades are most effective when the tissue to be resected is soft and compliant and can be suctioned into a cutting aperture of the shaver blade.
- alternative resection technologies such as Laser and Radio Frequency Ablation are used to remove tougher tissues
- the cutting instrument of the invention divides the cutting action into two components, the first replacing aspiration to draw tissue into the blade, and the second acting to sever the tissue drawn into the blade.
- the first component includes slicing into the tissue with a helical knife to draw tissue against a fixed cutting edge, and the second component includes cutting the tissue into discrete pieces with the cutting edge.
- a cutting instrument includes an outer member having a cutting edge, and a helical knife coupled to the outer member for rotation relative to the outer member. At least a portion of the helical knife extends distally beyond the cutting edge of the outer member.
- Embodiments of this aspect of the invention may include one or more of the following features.
- the instrument includes an inner member received within the outer member.
- the helical knife is located at a distal end of the inner member.
- a clearance between the inner member and the outer member may be for example in the range of about 0.00127 to 0.00508cm (0.0005 to 0.002 inches).
- the inner member defines an aspiration opening and the aspiration opening is located at a proximal end of the helical knife.
- the helical knife includes a helical edge and a helical channel.
- the helical channel has a proximal end, a distal end, and a pitch. The pitch of the helical channel increases from the distal end to the proximal end.
- the helical channel terminates in an aspiration opening through a wall of the inner member.
- the instrument includes a hub coupling the inner member to the outer member.
- the outer member defines a fluid ingress opening.
- the fluid ingress opening is located at a distal region of the outer member.
- the cutting portion is located at a distal end of the outer member and tapers to a sharp cutting edge.
- the cutting edge is located at a distal end of the outer member.
- the outer member tapers to the cutting edge.
- the cutting edge is a circumferential cutting edge that is, for example, circular in shape. Alternatively, the cutting edge is part-circumferential and is, for example, circular or oblong in shape.
- the outer member includes a shield portion extending distally from the cutting edge.
- a method of cutting includes slicing into tissue with a helical knife to draw tissue proximally toward a cutting portion, and cutting the tissue with the cutting portion.
- Embodiments of this aspect of the invention may include one or more of the following features.
- the helical knife is provided on an inner member and the cutting portion is provided on an outer member.
- the method includes transporting cut tissue along a helical channel defined by the helical knife, and aspirating the cut tissue through a hollow interior in the inner member.
- Aspirating the cut tissue includes aspirating the cut tissue through an opening in a wall of the inner member.
- the method further includes aspirating fluid through an opening in the outer member.
- Conventional shaver blades rely on suction or mechanical force to introduce tissue to a blade for cutting the tissue resulting in tough tissue, such as intrauterine fibroids and meniscal cartilage, not being cut by the blade.
- the two component cutting action of the surgical cutting instrument of this invention overcomes this difficulty by first slicing into the tissue with a helical knife to draw the tissue against a cutting edge and then cutting the tissue into discrete pieces with the cutting edge.

- a surgical cutting instrument 100 for resecting tough fibrous tissues such as intrauterine fibroids and meniscal cartilage, includes an inner member 120 with a helical knife
- Cutting portion 135 has a cutting edge 134, and a portion 127 of helical knife 125 extends distally beyond the cutting edge 134.
- rotation of the inner member 120 causes portion 127 of the helical knife 125 to slice into the tissue, drawing the tissue proximally along the helical knife 125 and against the cutting edge 134 of the outer member 130.
- Tissue is cut into discrete pieces by cutting edge 134 and the pieces are aspirated away from the surgical site through instrument 100.
- the surgical cutting instrument 100 has a distal region 110 including helical knife 125 and cutting portion 135.
- Instrument 100 has a proximal region 190 at which the inner and outer members 120, 130 are coupled by a hub 180 (as is known for arthroscopic cutting blades having a stationary outer member and an inner member driven by a rotary driver).
- the inner member 120 is received inside the outer member 130.
- the outer diameter of the inner member 120 and the inner diameter of the outer member 130 are close fitting.
- the clearance between the inner and the outer members may be in the range of about 0.00127 to 0.00508cm (0.0005-0.002 inches) such that tissue drawn to the cutting portion 135 of the outer member 130 by the helical knife 125 is cut by a shearing action between the cutting portion 135 and the helical knife 125, like the cutting action of a scissors.
- the outer member 130 is tubular with a hollow interior 132.
- the cutting portion 135 tapers distally to the sharp, circular, circumferential cutting edge 134.
- the cutting portion 135 may be for example approximately 0.254cm (0.10 inches) in length L and tapers at an angle a of about 4°-5°.
- the outer member 130 defines an opening 136 through a wall 130a of the outer member 130.
- the opening 136 is an ingress for water or other fluids to enter the instrument to assist in removing cut tissue.
- the inner member 120 includes a proximal, tubular portion 150, and a distal portion 152.
- Proximal portion 150 defines a hollow interior 122.
- Distal portion 152 has a proximal section 154 defining a hollow interior 122a in fluid communication with hollow interior 122, and a solid distal section 158 defining helical knife 125.
- Proximal portion 150 has a distal region 160 with a decreased outer diameter, and distal portion 152 has a proximal region 162 with an increased inner diameter.
- distal region 160 of portion 150 is received within proximal region 162 of portion 152 and the two portions are welded together in region 123a.
- the helical knife 125 has a sharp-edged helix 121 and a helical channel 128.
- the helical channel 128 terminates proximally in an opening 126 through a wall 120a of the inner member 120.
- the helical knife 125 has a blunt tip 124 at its distal end.
- the helix 121 extends proximally from tip 124 and the pitch of the helix 121 , and thus of the channel 128, increases proximally from the blunt tip 124 to the opening 126, for example, from approximately 0.1651 cm (0.065 inches)at the blunt tip 124 of the helix 121 to 0.508 cm (0.20 inches) at the proximal end of the helix 121 at the opening 126.
- Sliced tissue is transported proximally along channel 128 to the cutting edge 134, where the tissue is cut into discrete pieces. The pieces of cut tissue are channeled through opening 126 into hollow interior 122a.
- the opening 126 is an ingress for cut tissue to enter the hollow interiors 122a, 122 of the inner member 120 to be transported away.
- the helical portion 121 of the inner member 120 has a predetermined axial length to allow for the change in pitch to channel tissue through opening 126 without clogging opening 126.
- the length of the helix 121 may be 0.64008 cm (0.0252 inches) where the helical knife 125 has a length of 1.6891cm (0.655 inches) and the overall length of the inner member 120 may be in the range 17.53108cm to 17.60728cm (6.902 to 6.932 inches).
- an operator holds the cutting instrument 100 against the targeted tissue.
- the cutting instrument can be oriented with angle, ⁇ , ranging from about 15° to 345°.
- the helical knife 125 of the inner member 120 is rotated clockwise and helix 121 slices into the targeted tissue.
- the helical knife 125 channels the tissue along the helical channel 128 to the cutting portion 135 where the tissue is cut into discrete pieces against the sharpened cutting edge 134.
- the discrete pieces are drawn further along the helical channel 128 of the helical knife 125, through the opening 126 of the inner member 120 and into hollow interior 122a to be aspirated along hollow interior 122.
- a cutting instrument 200 includes an outer member 230 with a chamfered, cutting portion 235 forming a cutting edge 234, and a shield portion 237 extending distally of cutting edge 234. Shield portion 237 extends distally beyond the distal end 124 of helical cutter 125, and circumferentially over about 180° of outer member 230 to partially cover helical knife
- Cutting edge 234 is part-circumferential, extending over about 180° of outer member 230. Rather than being perpendicular to the axis of the instrument, as in the embodiment described above, cutting edge 234 is formed at about a 45° angle to the axis of the instrument, such that cutting edge 234 has an oblong shape. Shield portion 237 and cutting edge 234 define a window 250.
- Helical knife 125 has a portion 227 extending distally beyond cutting edge 234 that is exposed to the tissue through window 250. As previously described, rotation of the helical knife 125 slices the helical knife 125 into targeted tissue, drawing the tissue proximally along the helical knife 125 and against the cutting portion 235 of the outer member 230 to be cut by the cutting portion 235.
- a surgical instrument 300 has an outer member 330 with a circular, part-circumferential cutting edge 334 formed perpendicular to the axis of the instrument, and a shield portion 337 extending distally of the cutting edge 334.
- the shield portion 337 extends about less than 180°, for example, shield portion 337 extends about 120°, of the outer member 330 to expose more of the helical knife 125.
- the instrument is placed tangentially against the tissue, and acts as a side cutter drawing the tissue laterally into the helical channel and axially, proximally along the helical channel to the cutting edge. A number of implementations have been described.
- a third member can be disposed around the outer member to create an annulus to introduce fluid to a surgical site.
- the dimensions of various parts of the cutting instrument may vary with the specific application for which the cutting instrument is used. Accordingly, other embodiments are within the scope of the following claims.
