Skin approximator

Claim 2

A medical device, particularly a skin approximator, comprising first means for engaging the skin at opposite sides of a wound; second means for drawing the skin together by way of said first means across the wound so as to close the same; third means for everting the edges of the skin by way of said first means before the edges move into a position of mutual abutment in response to operation of said second means, said first means being provided on said second means; means for movably connecting said second means with said third means; and means for facilitating disengagement of said first means from the skin.

Claim 3

A medical device as defined in claim 1, wherein said second means comprises a pair of sections which have respective free end portions and are hingeable relative to one another between a starting position in which said end portions are spaced further apart and an end position in which said end portions are closer together.

Claim 4

A medical device as defined in claim 1, wherein said first means comprises at least two skin-piercing barbs.

Claim 5

A medical device as defined in 1, wherein said third means comprises a pair of arms pivotably connected to said second means and each having a curved endface engageable with the skin at one of the opposite sides of the wound.

Claim 6

A medical device as defined in 1, wherein said third means comprises a pair of arms pivotably connected to said second means and each having a curved endface engageable with the skin at one of the opposite sides of the wound.

Claim 7

A medical device as defined in claim 4, wherein said first means comprises at least two skin-piercing barbs each provided on one of said endfaces.

Claim 8

A medical device as defined in claim 5, said arms being L-shaped and each having a longer section and a shorter section provided with the respective endface, said longer and shorter sections of each arm being joined with each other at a juncture and the respective pivotable connections defining a pivot axis which passes through said juncture.

Claim 9

A medical device as defined in claim 6, said longer sections having respective end portions proximal to each other and each distal from said junction; and means pivotably connecting said end portions to one another.

Claim 10

A medical device as defined in claim 6, said barbs being elongated and each having a longitudinal center axis; and said endfaces being curved on a radius which is eccentric relative to said center axis.

Claim 11

A medical device as defined in claim 1, said second means comprising a pair of sections having respective free first end portions carrying said third means, said sections being hingeably displaceable relative to one another between a starting position in which said end portions are further apart and an end position in which the end portions are closer together, and said sections further having second end portions distal from said first end portions; and means connecting said second end portions for said hingeable displacement.

Claim 12

A medical device as defined in claim 9, wherein the lastmentioned means comprises a pivot connecting said second ends.

Claim 13

A medical device as defined in claim 9, wherein the last mentioned means comprises a portion which is unitary with and connects said second ends to one another.

Claim 14

A medical device as defined in claim 1, wherein at least some of said means are at least in part of metallic material.

Claim 15

A medical device as defined in claim 1, wherein at least some of said means are at least in part of synthetic plastic material.

Claim 16

A medical device as defined in claim 1, said second means comprising a pair of elongated sections which are hingeable relative to one another, said facilitating means comprising finger-engaging and positioning means on said sections.

Claim 17

A medical device as defined in claim 14, wherein the facilitating means is in form of finger-receiving loops on said sections.

Claim 18

A medical device as defined in claim 1, wherein at least said second and third means are unitary with each other in form of a one-piece molded unit of synthetic plastic material.

Claim 19

A medical device, particularly a skin approximator, comprising first means for engaging the skin at opposite sides of a wound; second means for drawing the skin together across the wound so as to close the same; and third means for everting the edges of the skin before they move into a position mutual abutment in response to operation of said second means, said third means comprising a pair of L-shaped arms pivotably connected to said second means and each having a curved endface engageable with the skin at the opposite sides of the wound, each of said arms including a longer section and a shorter section provided with the respective endface, said longer and shorter sections of each arm being joined with each other at a juncture and the respective pivotable connections defining a pivot axis which passes through said juncture, said longer sections having respective end portions proximal to each other and each distal from said junction, said end portions being free of connection to one another but engaging each other in pivotal relationship in response to operation of said second means, said first means comprising at least two skin piercing barbs each provided on one of said endfaces.

Claim 20

A medical device, particularly a skin approximator, comprising first means for engaging the skin at opposite sides of a wound; second means for drawing the skin together across the wound so as to close the same; and third means for everting the edges of the skin before they move into a position mutual abutment in response to operation of said second means, said third means comprising a pair of L-shaped arms pivotably connected to said second means and each having a curved endface engageable with the skin at the opposite sides of the wound, each of said arms including a longer section and a shorter section provided with the respective endface, said longer and shorter sections of each arm being joined with each other at a juncture and the respective pivotable connections defining a pivot axis which passes through said juncture, said longer sections having respective end portions proximal to each other and each distal from said junction, said end portions being free of connection to one another but engaging each other in pivotal relationship in response to operation of said second means, said first means comprising at least two skin piercing barbs each provided on one of said endfaces.
