Definitions

  • the invention generally relates to a mesher for perforating a material.
  • the invention relates to a mesher device for use in medical and/or surgical applications.
  • Skin graft meshers are designed to incise and "mesh" a piece of natural or artificial skin prior to grafting in order to allow it to expand and cover a larger area than its donor site area.
  • the common expansion ratio for dermal meshers is 1 :1.5, meaning that a piece of skin can be meshed to cover one and a half times more surface area than the size of the donor site.
  • the apertures created also provide improved drainage to exudate from the recipient site.
  • Conventional meshing systems an example of which is shown in Figure 1 include a mesher containing a cutting drum (roller) and skin graft carriers. Problems associated with this design, particularly in a medical environment, include, but not limited to:
  • a device for puncturing a material comprising; a) a support member for supporting the material,
  • a disposable puncturing element carrier having a plurality of puncturing elements associated thereon for use in the device according to the first aspect of the invention.
  • a kit comprising a puncturing element carrier having a plurality of puncturing elements associated thereon and a material support member.
  • a material manufactured using the device according to the first aspect of the invention According to a fifth aspect of the invention there is provided a skin graft substitute prepared using the device according to the first aspect of the invention.
  • tissue or tissue substitute mesher device for use in perforating the tissue or tissue substitute, the device comprising;
  • a support member for supporting the tissue or tissue substitute
  • a disposable tissue or tissue substitute mesher device for use in perforating the tissue or tissue substitute, the device comprising;
  • a support member for supporting the tissue or tissue substitute
  • the types of and the arrangement of the puncturing elements on the carrier can differ depending on the particular application.
  • Suitable puncturing elements would be known to a man skilled in the art, and can include, for example, spikes, needles and blades.
  • the puncturing elements can be made of a metal or a plastic having a suitable rigidity.
  • the puncturing element carrier can be made of a metal or a plastic.
  • the puncturing elements can be manufactured as an integral part of the puncturing element carrier.
  • at least the puncturing elements and the puncturing element carrier are disposable.
  • the puncturing elements can be associated with the puncturing element carrier post-manufacture.
  • the puncturing elements can be individually associated with the carrier, although this will be time consuming and would require substantial dexterity.
  • the puncturing elements are provided on a carrier material which itself can be associated with the puncturing element carrier. For example this carrier material can be adhered to the carrier, such that after use, the carrier material (with associated puncturing elements) can be removed from the carrier and disposed of.
  • the support member is preferably provided with a plurality of perforations which are complementary to the pattern of the puncturing elements, such that the puncturing elements can pass completely through the support member. This minimises the blunting of the blades and additionally ensures that the perforations completely traverse the material.
  • the puncturing element carrier can be provided with means that will enable it to be hand-held such that the user can puncture the material using a simple stamping action, in some situations it may be desirable to ensure an even application of pressure to the material and/or an increased pressure may be required for resilient materials. Therefore, in further embodiments of the invention the support member and the puncturing element carrier are located in a stand such that the reciprocal movement of i) the puncturing element earner towards the support member and/or ii) the material support member towards the puncturing element carrier is guided by the walls of the stand.
  • the walls of the stand are provided with grooves within which the puncturing element carrier and/or the material support member are received and moveable. This ensures that the puncturing elements contact the material in an even manner.
  • the material support member is static and the puncturing element carrier is moveable theretowards.
  • the puncturing element carrier is static and the material support member is moveable theretowards.
  • At least i) the puncturing element carrier towards the support member and/or ii) the material support member is provided with a handle, such as a plunger.
  • the mesher can be used to perforate a wide variety of materials in a range of applications.
  • the materials can be natural, synthetic or composites thereof.
  • the mesher can be used in surgical and medical applications.
  • a human or non-human animal tissue such as a skin graft or a skin substitute material.
  • the skin graft or skin substitute material can be derived from natural and/or synthetic materials.
  • Such skin substitute materials include, for example, dermal replacement products and epidermal replacement products.
  • a specific example of a product is a split thickness skin graft.
  • the mesher can be used for the perforation of dressings, such as wound dressings.
  • dressings such as wound dressings.
  • OPSITETM Smith & Nephew, Inc
  • non-surgical/medical applications of the mesher can be envisaged in which the perforation of a material is required.
  • the perforation of a material is required.
  • the components of the device are sterile.
  • the following components of the device are disposable;
  • the entire device When used for surgical and medical applications it is advantageous that the entire device is disposed of following use on a particular patient, thereby preventing any chance of cross-contamination between patients.
  • Figure 1 A photograph of a conventional skin graft mesher
  • Figure 2 A photograph of a skin graft having a mesh-like appearance
  • Figure 3 A schematic of an embodiment of the device according to the invention
  • the device comprises a stand 1 having a base 1a from which two arms members 1 b upwardly project when in use.
  • the static material support member 2 bridges the two arm members and is substantially parallel with the base.
  • the puncturing element carrier 3 is provided with a plurality of puncturing elements 4.
  • the carrier is located above the material support member 2 and and is moveable relative thereto.
  • a plunger 5 is provided on the upper surface of the carrier.
  • the device is sterile.
  • the device is disposable. Directions for use:
