Definitions

  • the invention relates to a curette comprising a handle-like handle with an outgoing from one end annular cutting edge.
  • Curettes are used not only in the dermatological, diagnostic and therapeutic fields, but also more recently in plastic surgery or gynecology.
  • the goal of curettage is the removal of superficial areas of the skin without damaging the surrounding tissue or minimizing it.
  • the curette d. H. Its annular cutting edge is extremely sharp and thus ensures a precise and gentle tissue removal, which also allows its use in the treatment of superficial malignant tumors.
  • Ring curettes are similar in size and weight to a fountain pen. Characteristic of corresponding curettes is their easy handling. Usual diameters of the annular blades may be 4 mm and 7 mm, respectively.
  • a surgical knife according to US-B-7,387,637 can be covered by means of a sleeve, which is displaceable along the handle of the knife.
  • the sleeve can be latched both in its position releasing the blade and in its position covering the blade.
  • the invention essentially provides that with the handle a protective element is connected, which extends in a first detent position spaced from the cutting edge and at least partially covers the cutting edge in a second detent position, in particular with the handle a perpendicular to its longitudinal axis pivotable protective element is connected, which in a Nutzwolf forming a first detent position spaced from the cutting edge and in a second detent position, the cutting edge covers at least in sections.
  • the invention provides that the protective element has a flat-cuboid geometry with a width which corresponds approximately to the width of the handle in the region in which the protective element is in its first detent position and at least partially rests flat on the handle.
  • a latching element which in the first latching position laterally comprises the handle.
  • the latching element has an arcuate geometry, wherein the latching elements extending from the respective longitudinal edge with a region of the protective element extending between them have a geometry following a section of an oval.
  • the latching elements should extend in relation to the pivot axis of the protective element in its distal region, in particular spaced from the pivot axis remote end.
  • a protective element forming a folding mechanism is integrated on the handle of the curette, which can be unlocked and folded with a finger or the thumb. After use of the curette this is pivoted to then engage in a snap or latching mechanism such that a loosening usually, ie without manipulation is not possible.
  • the protective element preferably has a latching recess in its distal region, into which at least one projection projecting from the handle engages in the second latching position.
  • the protective element may preferably have in its distal region a latching projection which engages in the second detent position in an existing in the handle latching recess such as recess.
  • the protective element has a first plane spanning and preferably at least partially in the first detent position surface resting on the handle first section and inclined to the first plane extending and remote from the pivot axis second section, which in the second detent position extends beyond the distal portion of the cutting edge.
  • the annular cutting edge is covered by the front end of the protective element, thus protecting the user from injury.
  • the first section may have a length LI and the second section a length L2 with 3 L2 ⁇ LI ⁇ 7 L2.
  • the handle should have a circular cross-section and be flattened at least in the region of the first detent position of the protective element, ie in the region along which the protective element extends.
  • the free end of the second section lies in a second plane extending parallel to the first plane spanned by the first section, and that the blade runs at least in sections between the first and the second plane.
  • FIG. 3 shows a section along the line B-B in Fig. 1,
  • FIG. 4 shows the top view of the curette according to FIG. 1 with the protective element covering the cutting element
  • FIGS. 1 and 2 show an embodiment of a curette 10 developed according to the invention, which in a known manner consists of a grip part 12 and an annular cutting edge 14 present in the distal region. 2, the curette 10 is shown in the delivered state. In this case, the cutting edge 14 is covered by a hollow truncated cone-shaped protective cap 16 which is latched to the handle 12.
  • Fig. 1 the curette 10 is in the use state, d. h. Precise and gentle, a tissue can be removed by means of the annular cutting edge 14.
  • the cutting edge 14 is uncovered.
  • a protective element 18 pivots out from the handle 12 of the curette 10.
  • the protective element 18 has, in an end region 20, which is referred to as the proximal end region, a recess 22 which is delimited by a pivot axis forming shaft 24, which is connected to the protective element 18.
  • the shaft 24 is received by over a flattened portion 26 of the handle 12 projecting receiving elements 28, 30 so as to pivot the protective element 18 from the first position shown in FIGS. 1 and 2 to the position shown in FIGS. 4 and 6 can be seen and in which the annular blade 14 is covered in a circumference of a front portion 32 of the protective element 18 that a risk of injury is excluded.
  • a corresponding web may be formed integrally with the protective element 18 to specify the pivot axis.
  • the front or distal portion 32 of the protective member 18 is inclined to a main portion 34 which rests in the first position in which the curette 10 can be used, flat or substantially flat on the flattened portion 26 of the handle 12, as shown in FIG clarified. It can also be seen from this representation that the annular cutting edge 14 spans a plane which runs parallel to the flattened section 26 or a plane spanned by this.
  • Figs. 1, 2 and 3 indicate the first locking position of the protective element 18 again.
  • the protective element 18 is pivoted in the direction of the cutting edge 14, in order then to lock in a position in which the cutting edge 14 is covered in a circumference of the front or second portion 32 of the protective element 18, that an injury sgefahr is excluded.
  • the front free edge of the distal, ie front angled portion 32 extends in a plane parallel to the flattened portion 26 in or - viewed from the section 26 - above the lower edge of the annular blade 14 is located.
  • Figs. 4, 5 and 6 indicate the second detent position of the protective element 18 again.
  • the latching elements 42, 44 are in the exemplary embodiment hook-shaped edges of a U-shaped element that can be manufactured separately and inserted into the curette 10 or over the handle 12 overmolded and superimposed metal strips 46, 48 may be fixed, which merge into the annular cutting edge 14 ,
  • the U-shaped element can also be produced during the extrusion coating of the metal strips 46, 48, that is to say integrally with the handle 12. This is the preferred variant.
  • the proximal or first portion 34 of the protective element 18, which rests in the use position or in the first detent position on the flattened portion 26 of the handle 12, has a length which is preferably 3 to 7 times greater than the angled second portion 32.
  • the sections 32, 34 may further include an angle between 20 ° and 40 °.

Abstract

Curette qui comporte un manche de type tige pourvu d'une lame de coupe annulaire partant d'une extrémité du manche. L'objet de la présente invention est d'assurer une protection fiable contre les blessures après utilisation. A cet effet, un élément de protection est relié au manche et peut pivoter verticalement par rapport à l'axe longitudinal de ce dernier. Dans une première position d'enclenchement constituant une position d'utilisation, ledit élément de protection se trouve à une certaine distance de la lame de coupe et après utilisation terminée de la curette, dans une seconde position d'enclenchement, ledit élément de protection recouvre au moins par endroits la lame de coupe.
