Definitions
- a disposable skin-impaling and retracting or bone holding and retracting device comprises a support member from which is supported and extends a skinimpaling or bone-holding member most advantageously formed of cannulated needle stock the end portion of which is bent to form a skin-impaling or bone-holding hook, the tip end of which is beveled to form a relatively sharp point.
- the cannulated needle stock is bent preferably so-the bevel ison the outside of the bend therein.
- the support member may form a handle which is grasped during the manipulation of the device in a surgical procedure, or the support member may form a hub adapted removably to receive a separate handle member.
- the disposable device is packaged in a container which seals the same from the atmosphere, and is pre-sterilized so as to be ready for immediate use when the container is opened.
- the present invention overcomes the disadvantages of the prior art, namely the relatively high cost, the need for washing and sterilization at the hospital and frequent repair or replacement of the reusable skin hooks, and the aforementioned difficulties with the improvised skin hooks, by providing an inexpensive disposable skin hook which is packaged in'a sterilized condition for immediate use in emergency or operating rooms.
- the skin hook device comprises a support member from which is supported and extends a skin hook member made of a relatively inexpensive thin metal stock whose end portion is bent into a hook.
- the surgical device is placed in a suitable package-forming container which seals the same from the surrounding atomsphere, and is.pre-sterilized in the container which is openable to make it immediately available for use.
- the support member is a short hub with means for. removably receiving a reusable stainless steel handle or the like.
- the support member forms a relatively long integral handle so that the device is ready for immediate use when removed from the sealed container.
- the skin hook portion of the device is made from cannulated needle stock, which is a very inexpensive and readily available material.
- a cannulated needle stock is used which is at least about 0.028 inches (22 gauge) in diameter.
- the cannulated needle stock is bent so that the bevel is placed on the outside of the bend, since if the bevel is on the inside of the bend the two sharp edges formed by the bevel can readily damage the skin tissue by cutting therethrough, and act as a means for catching'tissue in the hollow of the needle, which damages the skin tissue when the skin hook device is removed upon completion of the surgical maneuver.
- the diameter of the cannulated needle stock should be at least about 0.05 inches (i.e. at least about 18 gauge stock which is 0.049 inches in diameter).
- FIG. 1 is a longitudinal sectional view through a sealed container housing a pre-sterilized,'disposable skin or bone hook constructed in accordance with the most preferred form of the invention, wherein the skin or bone hook within the container includes a skin or bone-engaging member formed from cannulated needle stock attached to a relatively long handle;
- FIG. 2 is a view of the skin or bone hook of FIG. 1 removed from the container, and shows the handle portion of the skin or bone hook in longitudinal section;
- FIG. 3 is a greatly enlarged transverse sectional view through the assembly of the container and the skin or bone hook of FIG. 1, taken along section line 3-3 therein;
- FIG. 4 illustrates the use of the skin hook form of the invention in the process of raising skin from the underlying tissue
- FIG. 5 illustrates a pair of bone hooks of the invention used to align a pair of severed bone sections
- FIG. 6 illustrates a longitudinal sectional view through a sealed container housing a modified form of a pre-sterilized, disposable skin or bone hook'of the invention, wherein the skin or bone hook is packaged without a handle and is adapted to receive removably thereon a reusablehandle;
- FIG. 7 is a view of the skin or bone hook shown in FIG. 6 removed from the container and in juxtaposition to a reusable handle attached thereto;
- FIG. 8 is a view of the skin or bone hook and reusable handle of FIG. 6 when assembled, with the handle being shown in longitudinal section.
- a sealed container 4 is shown in which is supported a pre-sterilized disposable skin or bone hook unit generally identified by reference numeral 6.
- the skin or bone hook unit 6 includes a relatively long handle 8 which is most advantageously made of a suitable synthetic plastic material. Although it may have other shapes, the handle 8 is shown with a non-circular cross-section to present a number of easily graspable longitudinal planes or the like.
- the handle also may be transversely indented to form closely spaced transverse serrations or ridges to provide with the longitudinal ridges a checkered rough surface to facilitate a firm grasp of the handle 8.
- the skin or bone hook unit 6 further includes a hookforming member which, in the most preferred form of the invention, is constructed of inexpensive cannulated needle stock having a main straight shank portion 10a extending longitudinally from one of the ends of the handle 8 acting as a support member for the hookforming member 10, and an end portion 10b bent in the form of a hook.
- the cannulated needle stock forming the hook-forming member 10 is beveled at the exposed tip thereof at 12, the bevel being placed on the cannulated needle stock before it is bent into the hook shape as shown.
- the bevel is on the outside of the bend in the cannulated needle stock.
- the shank portion 10a of the hook-forming member in the case where the handle 8 is made of synthetic plastic material, most advantageously extends the full length of the handle 18 so it contributes to the strength and rigidity of the handle 8.
- the present invention envisions the shank portion 10a extending only a short distance within the handle 8.
- the handle 8 is made of synthetic plastic material
- the handle may be molded in place around the hook-forming member 10.
- the position of the hook-forming member projecting from the handle 8 should have a length of at least about three/fourths to 1 inch.
- the handle 8 forms a secure anchoring support for the hook-forming member 10. While the exact manner in which the hook-forming member 10 is anchored to the handle 8 may vary widely, as illustrated, the hookforming member has applied thereto before the handle is molded thereover a coating 16 ofa suitable material, which may be an epoxy or other synthetic plastic material, forming a bead portion 16a to be located at the inner end of the handle 8 and a grooved portion 16b to be located within the handle 8, to form anchoring grooves for the synthetic plastic material forming the handle 8.
- a coating 16 ofa suitable material which may be an epoxy or other synthetic plastic material
- the skin or bone hook 6 is sealed within the container 4, which may take a variety of forms other than that illustrated.
- the container could be a paper package or, as illustrated, a container made of a synthetic plastic material, which can be easily opened to permit ready access to the skin or bone hook 6.
- the container 4 includes a main body portion 4a having cylindrical wall portion 18 defining a main cylindrical cavity 19 therein which is closed at one end by an end wall 20 and is opened at the other end.
- the cylindrical wall portion 18 of the main body portion 4a of the container 4 is most advantageously provided with a longitudinal groove or indentation 24 which forms a space for the hook end portion 10b of the hook-forming member 10.
- the handle 8 of the skin or bone hook 6 is slidably received within the cylindrical cavity 19, while the groove 24 provides clearance for the passage of the hook-forming member 10 into and out of the cavity 19 of the main body portion 4a of the container 4 as the skin or bone hook is placed in or removed from the container.
- the outer end portion of the handle 8 preferably projects a distance of about one-quarter inch or more from the open end of the main body portion 18, so such projecting end portion may be readily grasped by the user to remove the skin or bone hook 6 readily from the container.
- a suitable cap member 4b which is illustrated as being a cup-shaped member including a cylindrical side wall 26 and an end wall 28 at one end of the cylindrical side wall 26, the cylindrical side wall being modestly flexible and resilient and terminating at an open end of the cap member 4b in a continuous annular rib 30 or the like which snaps into a corresponding continuous annular groove 32 formed in the outer surface of the main body portion 18 of the container 4, to form a pressure seal which seals the interior of the container from the contaminating elements of the surrounding atmosphere.
- the frictional forces between the rib 30 and the groove 32 are such that the cap member 4b may be pulled from the main body portion 18 with a modest application of force.
- the surface of the cap member may be knurled.
- FIGS. 4 and 5 respectively show the use of one or more skin or bone hooks 6 in the engagement and retraction of the skin 27 from the underlying tissue 34 as the skin 27 is being cut away from the underlying tissue 34 by a knife or scissors 35 and the retraction of a pair of broken small bone segments 36 and 38 into alignment during a bone setting operation.
- the hook-forming member 10 when made of beveled cannulated needle stock should have a diameter of at least about 0.028 inches, and when the hook-forming member 10 is used as a bone hook it should have a diameter of at least about 0.05 inches.
- FIGS. 6-9 show another form of the invention where a skin or bone hook 6' is packaged without a handle so the packaged assembly becomes a more compact and inexpensive unit for use with a reusable handle 40 made of surgical stainless steel or the like.
- the support member 8' for the hook-forming member 10 of the skin or bone hook 6 is a relatively short hub member 8', which may be made of synthetic plastic material like the handle 8 previoysly described.
- the hub member 8, when made of synthetic plastic material, is molded around the inner end portion of the hook-forming portion 10' of the skin or bone hook.
- the shank portion 10a of the hook-forming member It has a coating 16' of an epoxy material or the like which is grooved and beaded to aid in making a secure connection between the hub member 8' and the hook-forming member Ml.
- the shank portion 10a of the hook-forming member It) thereof terminates short of the end of the hub member 8', and beyond the end of the hook-forming member 10' the hub member is provided with an internally threaded socket 42 adapted to receive the externally threaded neck portion 44 of the reusable handle 46.
- the skin or bone hook 6' may be sealed and sterilized within a container 4 similar to the container 4 shown in FIG. ll, container 4' being of only sufficient length to accommodate the shorter skin or bone hook 6'.
- container 4' is of only sufficient length to accommodate the shorter skin or bone hook 6'.
- the outer end portion of the hub member 8' projects a distance like at least about one/fourth inch beyond the end of the main body portion 4a of the container 4', so that the skin or bone ously described in connection with the embodiment of I the invention shown in FIG. 1.
