Definitions

  • the present invention relates to a positioning aid for hand surgery comprising a plate with openings and means for releasably fixing the hand to this plate in the form of reins, each of which can be passed through the apertures in the plate and are each laying around a finger of the hand to to fix this finger on the plate.
  • the loan markets must be bent together for sterilization, so that they fit into the standard 200 mm standard sterilization films. There they are shrink-wrapped for later sterilization. The bending leads to a considerable application and bulges the films. The standard sterilization films therefore usually do not fit. Due to the bending and the resulting shape of the hand holder injury to the sterilization film is not uncommon even during storage. This inevitably leads to contamination of the lead hand.
  • the bands are made of an elastic material, for example, wider rubber bands are used, so that due to the elasticity of a certain degree of freedom for the respective diameter of the finger of the person is given.
  • the position in which the straps are secured to the plate is dictated by the position of the respective slots in the plate through which the straps are passed, thus leaving hardly any degrees of freedom. This is to be regarded as disadvantageous since both the size of the hand, which is to be fixed, as well as their anatomical shape, the length and the thickness of the fingers can vary greatly.
  • the thumb ring serves primarily to keep the thumb at a distance from the palm, so that the person to be operated does not bend, for example, the thumb, thereby disturbing the surgeon.
  • the slots for the remaining fingers are at most fixing degrees of freedom in terms of length
  • an adaptation to different finger thicknesses is difficult in this known device.
  • the object of the present invention is to provide a positioning aid for hand surgery of the aforementioned type, which results in a greater variability in terms of the possibilities for fixing the hand and the fingers of the patient.
  • the plate has each finger of the hand associated holes for fixing reins, wherein for each finger in each case at least two in the direction of expansion of the applied finger each spaced holes on each side of the finger, in the intended support position of the finger on the plate, are provided.
  • the power is freely adjustable.
  • the plate does not have to be bent when changing sides. A material fatigue and surface change by bending as in the lead plates described above is excluded.
  • the reins used in the invention are narrower than the wide bands used in the prior art. They can be stretched from hole to hole and thus need not necessarily be stretched parallel between holes at the same height, but can also be stretched almost diagonally between two holes, which results in significantly more different attachment positions, therefore more degrees of freedom are given and the attachment total is more flexible. There are also more points at which the respective finger can be positioned and how it can be positioned. This is important, for example, if you have to operate on the finger itself.
  • the holes according to the invention are holes in the plate, which are adapted in their diameter to silicone reins, as in operating theaters for various used for other purposes, such as for the tethering of vessels, nerves, tendons, etc.
  • These silicone tethers may for example have a diameter of the order of about 3 mm. They are passed through the holes / holes, with a simple knot in the silicone reins preventing it from slipping through the hole.
  • the fixation force can be roughly determined by appropriate localization of the node and by selecting the respective fixation holes on the plate.
  • At least one finger position on at least one side of the finger at least three mutually spaced holes are arranged in alignment approximately in a row. Due to the relatively high number of holes, it is possible that the surgeon threading the reins so that he can, for example, after operation of one hand turn the plate and then use the already threaded reins, at least partially, for the other side, so he has less threading.
  • At least one finger position on both sides of the finger in each case at least three holes spaced apart from each other are arranged in alignment approximately in a row with one another.
  • At least three mutually spaced holes are arranged in alignment with each other approximately in a row.
  • At least four or more spaced apart holes may be aligned with each other approximately in a row.
  • additional holes are arranged in the plate in addition to the holes aligned in a row each other, which form further fixing points for the reins.
  • These additional additional holes may be located, for example, in a central region of the plate (approximately in the area of the lower finger links of the index finger, middle finger and ring finger).
  • the plate to which the hand is fixed for example, be made of stainless steel or aluminum. These materials are more hygienic and lighter than lead plates, for example, and are particularly suitable as materials for hand surgery.
  • the plate When using aluminum, the plate can be coated, for example, with a preferably non-conductive Silacoat according to a preferred embodiment of the invention.
  • a development of the present invention provides that on at least one side of the plate, a side label and / or a schematic drawing of a hand are applied.
  • the plate can be used for both hands. If a page break (right hand, left hand) is required, simply flip the plate over so the thumb holes are in place.
  • the plate on which the hand 9 of the person to be operated is placed is designated by the reference numeral 10.
  • this plate 10 has an approximately rectangular plan and is designed in size so that on her a larger hand has enough space when the hand is placed up to the wrist. On the top, the plate may be slightly rounded. Above the hand 9 and laterally on both sides next to the hand, there is still some space left when the hand 9 is put on.
  • the plate 10 is provided with a label 11 a, 11 b, for example, with the letters "R" and "L", so that you can use the plate 10 either for the right or for the left hand and the surgeon knows in which Hand which side of the plate is at the top.
  • the plate 10 has a total of five areas in which it has a plurality of holes, these five areas herein being referred to by the term "finger positions". For each finger position thus includes several holes that provide the ability to fix each of the corresponding finger on the plate variable. In addition, however, it is also possible to use for determining one of the fingers holes from the range of the finger position of another finger, resulting in even more degrees of freedom in the fixation of the individual fingers.
  • the plate additionally has some holes, which are located somewhat further down than the holes shown here, ie not in the area of the upper phalanxes, but somewhat further in the direction of the lower phalanges or the metacarpus area, such additional holes are not specifically associated with a specific finger position but can be variably used for one or the other finger optionally, depending on how the respective anatomical conditions in the corresponding person whose hand is fixed.
  • the hand can be different in width and length, it can be different thickness, the length and thickness of the fingers can vary and their shape and their position on the hand. Therefore, it is advantageous if a particularly large number of holes is present, which allows a very variable fixation of the fingers and the hand for individual adaptation to the anatomical conditions.
  • the plate 10 thus has a thumb position 12, an index finger position 13, a middle finger position 14, a ring finger position 15 and a finger position 16 for the little finger.
  • Each of these five finger positions are each assigned a plurality of holes, in the present case after a particular hole pattern.
  • a hole pattern was selected with two rows of two or three holes, which are located on both sides in each case next to the finger in the respective finger position.
  • three holes 12 a, 12 b are present, which are each spaced apart, forming a row on each side of the finger and in this row are approximately aligned.
  • two times three i.
  • each finger position which lie in pairs opposite each other on both sides of the applied finger.
  • each finger it is possible for each finger to make several fastenings each reins, which extend in the attachment position across the finger. But you can also provide for each finger only one attachment, for example, more in the area of the fingertip or on the second or third phalanx.
  • you can also use holes for the attachment of a finger which are actually in the range of another finger position, because you do not necessarily need all the holes for one finger, so that for a reins also two holes can be used, the farther apart are removed.
  • FIG. 2 shows an alternative variant in which even more holes are provided for the individual finger positions than in the variant of FIG. 1 ,
  • the thumb position has a total of ten holes 12 a, 12 b, five each in two rows on both sides of the thumb. In the rows, the holes are each about aligned with each other.
  • the index finger position 13 a total of eight holes 13 a, 13 b are provided, in two rows of four holes on both sides of the applied index finger. Accordingly, eight holes are also provided for the other fingers here.
  • the holes in the rows can be denser, so with a smaller distance from each other, but they can also extend over a greater total length of the series, so that there are more attachment options available in the hand of an adult with long fingers.
