Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
190 words
A skin protector for protecting the skin incision from thermal and frictional abrasion caused by movements of a probe adapted and intended to move freely and continuously inside the skin protector during a surgical procedure, comprising a skin protector body made of ultrasonic-compatible material including first means forming a lower part for insertion into the incision to access the subcutaneous space and second means in one piece with said first means and intended to remain external of the skin, said second means providing limiting means for limiting the insertion depth of the first means of the skin protector in the subcutaneous space, said body being provided with a substantially aligned bore defining an axial direction and of a diametric dimension allowing free movement of a probe inside said skin protector during the surgical procedure, and further means directly on and integral with the outer surfaces of the lower part to enable anchoring of said skin protector body in the incision and thereby maintain the in-situ position of the skin protector by lessening the likelihood of unintentional withdrawal of the skin protector out of the incision during movements of the probe.
Claim 2
Dependent Claim
190 words
A skin protector for protecting the skin incision from thermal and frictional abrasion caused by movements of a probe adapted and intended to move freely and continuously inside the skin protector during a surgical procedure, comprising a skin protector body made of ultrasonic-compatible material including first means forming a lower part for insertion into the incision to access the subcutaneous space and second means in one piece with said first means and intended to remain external of the skin, said second means providing limiting means for limiting the insertion depth of the first means of the skin protector in the subcutaneous space, said body being provided with a substantially aligned bore defining an axial direction and of a diametric dimension allowing free movement of a probe inside said skin protector during the surgical procedure, and further means directly on and integral with the outer surfaces of the lower part to enable anchoring of said skin protector body in the incision and thereby maintain the in-situ position of the skin protector by lessening the likelihood of unintentional withdrawal of the skin protector out of the incision during movements of the probe.
Claim 3
Dependent Claim
44 words
A skin protector according to claim 1, wherein said limiting means includes abutment surface means intended to face the skin externally and having a cross-sectional area larger than the cross-sectional area through said lower part at a substantially right angle to the axial direction.
Claim 4
Dependent Claim
30 words
A skin protector according to claim 2, wherein said second means has a lower end surface, and wherein said abutment surface means is formed directly by said lower end surface.
Claim 5
Dependent Claim
19 words
A skin protector according to claim 2, wherein said abutment surface means is formed by an annular disk-like part.
Claim 6
Dependent Claim
31 words
A skin protector according to claim 1, wherein said anchoring means is formed by one of rib-like means, a textured outer surface of the lower part, barb means and threaded means.
Claim 7
Dependent Claim
46 words
A skin protector according to claim 5, wherein said lower part has an outer surface and a free end, and wherein said anchoring means is formed by at least one rib-like means provided over at least a portion of the outer surface of the lower part.
Claim 8
Dependent Claim
34 words
A skin protector according to claim 6, wherein said rib-like means is spaced from said limiting means by a distance corresponding approximately to the thickness of the skin consisting of the epidermis and dermis.
Claim 9
Dependent Claim
41 words
A skin protector according to claim 7, wherein said rib-like means is spirally shaped commencing in the area of the free end of the lower part and extends spirally upwardly about said lower part in the direction toward the limiting means.
Claim 10
Dependent Claim
34 words
A skin protector according to claim 8, wherein said spirally shaped rib-like means terminates at a distance from said limiting means corresponding approximately to the thickness of the skin consisting of epidermis and dermis.
Claim 11
Dependent Claim
15 words
A skin protector according to claim 1, wherein said lower part is of cylindrical shape.
Claim 12
Dependent Claim
26 words
A skin protector according to claim 1, wherein said second means includes means to facilitate implantation of the skin protector into the incision by rotary motion.
Claim 13
Dependent Claim
23 words
A skin protector according to claim 11, wherein said means to facilitate implantation is formed by a non-circular shape of the second means.
Claim 14
Dependent Claim
23 words
A skin protector according to claim 11, wherein said means to facilitate implantation is formed by non-smooth external surfaces of said second means.
Claim 15
Dependent Claim
43 words
A skin protector according to claim 11, wherein said means to facilitate implantation includes a driving member, and wherein said skin protector and driving member include coupling means to cause said skin protector to rotate in unison with rotation of said driving member.
Claim 16
Dependent Claim
16 words
A skin protector according to claim 14, wherein said coupling means is a mechanical coupling means.
Claim 17
Dependent Claim
16 words
A skin protector according to claim 14, wherein said coupling means is formed by complementary configurations.
Claim 18
Dependent Claim
42 words
A skin protector according to claim 1, wherein said skin protector body includes vacuum-assisted means to remove at least a large part of the emulsion and other fluid substances seeking to leak out through the space between a probe and the through-bore.
Claim 19
Dependent Claim
21 words
A skin protector according to claim 1, wherein said second means is formed at least in part by a disk-like member.
Claim 20
Dependent Claim
43 words
A skin protector according to claim 18, further comprising vacuum-assisted means incorporated into said disk-like member to remove at least a large part of the emulsion and other fluid substances seeking to leak out through the space between a probe and the through-bore.
Claim 21
Dependent Claim
15 words
A skin protector according to claim 18, wherein said disk-like member is of non-circular shape.
Claim 22
Dependent Claim
32 words
A skin protector according to claim 1, wherein said anchoring means terminates at a distance from said limiting means corresponding approximately to the thickness of the skin consisting of epidermis and dermis.
