Abstract
Abstract Suture tying forceps of improved construction are disclosed which materially reduce a suture being flexed therein from breaking. The suture typing forceps include a pair of members mounted in the free ends of a pair of gripping arms integrally joined at one end. The members terminate in a pair of suture tying tips, respectively featuring a pair of complementary mating surfaces serving as suture clamping surfaces. For the most part, the suture clamping surfaces are designed to clamp a suture segment which is about ten times the thickness of the suture. The suture clamping surfaces further are designed to define a flexing angle transversely thereof which is less than a right angle.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
159 words
Suture tying forceps comprising: (a) a pair of gripping arms integrally joined at one end, with the free ends thereof being normally in radially spaced relation; (b) a pair of members respectively secured in said free ends of said pair of gripping arms and terminating in a pair of suture tying tips; (c) said pair of suture tying tips formed with respective complementary mating surfaces designed to clamp a suture therebetween; (d) one of said pair of suture tying tips having a longitudinal U-shaped groove providing a cross sectional configuration comprising a U-shaped clamping surface and a pair of substantially flat planar flexing surfaces being contiguous with and extending downwardly from said U-shaped clamping surface; (e) the other of said pair of suture tying tips having a cross sectional configuration comprising a longitudinal U-shaped form in its central region and a second pair of substantially flat planar flexing surfaces being contiguous with and extending upwardly from said U-shaped form.
Claim 2
Dependent Claim
159 words
Suture tying forceps comprising: (a) a pair of gripping arms integrally joined at one end, with the free ends thereof being normally in radially spaced relation; (b) a pair of members respectively secured in said free ends of said pair of gripping arms and terminating in a pair of suture tying tips; (c) said pair of suture tying tips formed with respective complementary mating surfaces designed to clamp a suture therebetween; (d) one of said pair of suture tying tips having a longitudinal U-shaped groove providing a cross sectional configuration comprising a U-shaped clamping surface and a pair of substantially flat planar flexing surfaces being contiguous with and extending downwardly from said U-shaped clamping surface; (e) the other of said pair of suture tying tips having a cross sectional configuration comprising a longitudinal U-shaped form in its central region and a second pair of substantially flat planar flexing surfaces being contiguous with and extending upwardly from said U-shaped form.
Claim 3
Dependent Claim
35 words
The suture tying forceps of claim 1 wherein said one of said complementary mating surfaces in cooperation with said pair of substantially flat planar flexing surfaces define a flexing angle which is less than 90°.
Claim 4
Dependent Claim
42 words
The suture tying forceps of claim 1 wherein said pair of members are provided with means to align said pair of suture tying tips so that said complementary mating surfaces mate and remain mated when said forceps is operatively twisting said suture.
Claim 5
Dependent Claim
159 words
Suture tying forceps comprising: (a) a pair of gripping arms integrally joined at one end, with the free ends thereof being normally in radially spaced relation; (b) a pair of members respectively secured in said free ends of said pair of gripping arms and terminating in a pair of suture tying tips; (c) said pair of suture tying tips formed with respective complementary mating surfaces designed to clamp a suture therebetween; (d) one of said pair of suture tying tips having a longitudinal V-shaped groove providing a cross sectional configuration comprising a V-shaped clamping surface and a pair of substantially flat planar flexing surfaces being contiguous with and extending downwardly from said V-shaped clamping surface; (e) the other of said pair of suture tying tips having a cross sectional configuration comprising a longitudinal V-shaped form in its central region and a second pair of substantially flat planar flexing surfaces being contiguous with and extending upwardly from said V-shaped form.
Claim 6
Dependent Claim
159 words
Suture tying forceps comprising: (a) a pair of gripping arms integrally joined at one end, with the free ends thereof being normally in radially spaced relation; (b) a pair of members respectively secured in said free ends of said pair of gripping arms and terminating in a pair of suture tying tips; (c) said pair of suture tying tips formed with respective complementary mating surfaces designed to clamp a suture therebetween; (d) one of said pair of suture tying tips having a longitudinal V-shaped groove providing a cross sectional configuration comprising a V-shaped clamping surface and a pair of substantially flat planar flexing surfaces being contiguous with and extending downwardly from said V-shaped clamping surface; (e) the other of said pair of suture tying tips having a cross sectional configuration comprising a longitudinal V-shaped form in its central region and a second pair of substantially flat planar flexing surfaces being contiguous with and extending upwardly from said V-shaped form.
Claim 7
Dependent Claim
47 words
The suture tying forceps of claim 4 wherein one of said pair of complementary mating surfaces formed respectively on said pair of suture tying tips and said flexing surfaces adjacent said V-shaped clamping surface define a flexing angle transversely thereof which is less than a right angle.
