Claims
- 1. A surgical needle, comprising:
a linear body portion including:
a proximal end section; a central section; and a distal end section, the distal end section having a substantially parabolic configuration for producing a substantially uniform stress profile along a length thereof.
- 2. The surgical needle of claim 1, wherein the distal end section has a diameter determined according to the following equation:
- 3. The surgical needle of claim 2, wherein the distal end section includes a distal tip having a uniform taper.
- 4. The surgical needle of claim 3, wherein the distal tip has a length which is substantially equal to a diameter of the central section of the surgical needle.
- 5. The surgical needle of claim 1, wherein the proximal end section is configured and adapted to secure a suture thereto.
- 6. The surgical needle of claim 1, wherein the central section has at least one of a rectilinear, circular, oval, triangular, I-beam and ribbon shaped cross-sectional profile.
- 7. A uniform stress needle, comprising:
a proximal end section configured and adapted to secure a suture thereto; a central section having a uniform transverse cross-sectional profile; and a distal end section having a parabolic surface profile for producing a substantially uniform stress along a length thereof, the surface profile being defined by the following equation: d=(((32W)/(πσ))*(Xn)){circumflex over ( )}(1/3) where d=measured diameter at location Xn; W=load normal to the needle; Xn=distance from a distal-most end of the needle; and σ=a chosen stress restraint.
- 8. The uniform stress needle of claim 7, wherein the distal end section includes a distal tip having a uniform taper.
- 9. The uniform stress needle of claim 8, wherein the distal tip has a length which is substantially equal to a diameter of the central section of the needle.
- 10. A surgical needle, comprising:
a body portion including:
a proximal end section; a central section; and a distal end section, the distal end section having a substantially parabolic configuration for producing a substantially uniform stress profile along a length thereof, the distal end section including a distal tip having a uniform taper.
