Abstract
Abstract A deformable sheet material developed for surgical splints comprises a layer of resilient plastics material and a metal mesh reinforcement disposed in the plastics layer nearer one surface thereof. Both components are bendable, but the relative stiffness of the mesh inhibits the resilience of the plastics so that the sheet will `hold` in different curved configurations with the mesh innermost. Suitable materials are polyethylene and aluminium, and a cushion layer, suitably of irradiated expanded polyethylene, can be bonded to the one surface adjacent the mesh. Also, the sheet can be perforated.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
90 words
A redeformable surgical splint of the type having a concave inner face for placement adjacent to the body of a patient, a convex outer face and a predetermined thickness, said splint comprising a layer of resilient plastics material having a first surface defining said inner face, a bendable metal mesh reinforcement embedded in said layer to extend in said layer adjacent to said inner face, said layer having a second surface defining said outer face which is spaced a greater distance from said bendable metal mesh than said inner face.
Claim 2
Dependent Claim
90 words
A redeformable surgical splint of the type having a concave inner face for placement adjacent to the body of a patient, a convex outer face and a predetermined thickness, said splint comprising a layer of resilient plastics material having a first surface defining said inner face, a bendable metal mesh reinforcement embedded in said layer to extend in said layer adjacent to said inner face, said layer having a second surface defining said outer face which is spaced a greater distance from said bendable metal mesh than said inner face.
Claim 3
Dependent Claim
13 words
A sheet material according to claim 1 wherein said mesh has diamond-shaped interstices.
Claim 4
Dependent Claim
12 words
A sheet material according to claim 1 wherein said metal is aluminium.
Claim 5
Dependent Claim
13 words
A sheet material according to claim 1, wherein said plastics material is polyethylene.
Claim 6
Dependent Claim
18 words
A sheet material according to claim 1 comprising a layer of cushion material bonded to said one surface.
Claim 7
Dependent Claim
16 words
A sheet material according to claim 5 wherein said cushion material is an expanded plastics material.
Claim 8
Dependent Claim
15 words
A sheet material according to claim 5 wherein said cushion material is irradiated expanded polyethylene.
Claim 9
Dependent Claim
12 words
A sheet material according to claim 1, which sheet material is perforated.
Claim 10
Dependent Claim
33 words
A splint according to claim 1 wherein said configuration is a trough, and said mesh has diamond-shaped interstices with major and minor diagonal directions respectively extending transversely and longitudinally relative to said trough.
Claim 11
Dependent Claim
52 words
A surgical splint comprising at least two troughs as recited in claim 9, a deformable metal strip connected to each of said troughs to interconnect the latter in mutually-spaced generally longitudinal sequence, and a strap assembly connected to at least one of said straps to interconnect the opposed longitudinal side portions thereof.
