  • the present invention relates to the field of needles for anesthesia delivery, in particular, it relates to needles that require specific orientation to reach a target site and, more particularly, relates to a needle for delivering a light-oriented anesthetic.
  • anesthesia there are different ways of applying anesthesia to a patient, on the one hand, there is general anesthesia where the central nervous system is depressed, inducing, in the patient, a state of unconsciousness, muscle relaxation and loss of sensitivity, through supply of a general anesthetic. On the other hand, there is also local anesthesia, where the sensitivity of a small area of the body, such as a finger or a tooth, is eliminated.
  • epidural anesthesia where the spinal column is approached in the lumbar part and the epidural space is located inside.
  • some of the localization techniques are used to locate the epidural space, such as the Resistance Loss Techniques, Gutiérrez Gout Techniques, Dogliotti, etc.
  • the anesthesiologist must orient the needle to achieve an effective anesthetic procedure, this adjustment of the needle direction is performed to deliver an anesthetic to either a cephalic region or a caudal region.
  • epidural anesthesia anesthesia is supplied in the vicinity of the medulla in the epidural space and without perforating the meninges.
  • the needles used for these purposes there are needles with various shapes and characteristics in their cannula, that is, in the normally metallic conduit whose interior is called lumen, through which the medications flow to be administered to the patient body
  • the needles for anesthesia are differentiated at the end of the cannula, which has a generally bevelled tip, the "Tuohy” type needles being among the most commonly used, which have the characteristic that said tip is slightly curved.
  • the anesthesiologist knows at all times the orientation of the bevel to avoid excessive manipulation of the needle that can accidentally cause , the puncture of the dura mater and / or arachnoid meninges or damage the tissue through which the needle passes.
  • needle devices for anesthesia delivery with light indicators that are designed to locate the epidural space
  • needle devices with light indicators involve assemblies with complex electrical and / or electronic devices that include sensors and indicators of pressure to detect the change in pressure once the epidural space has been reached.
  • WO 2009/066972 discloses an electronic needle with spinal injection safety system
  • said electronic needle comprises a housing that has a light alarm that the user activates through a switch, wherein said alarm changes color when a pressure change is recorded when the epidural space has been reached.
  • this electronic needle is designed to detect when the bevel reaches the epidural space, however the light alarm of this device does not indicate bevel orientation, so the anesthesiologist needs to remember the orientation in which you initially inserted the needle. Likewise, as mentioned above, there is a risk that the anesthesiologist will forget to operate the switch or that, by mistake, said switch will be deactivated, making it even more difficult to know the orientation of the bevel.
  • WO 2012/089223 discloses a device for the detection of epidural space; However, this device is completely independent of the needle to deliver anesthesia, so it only detects the change in pressure in the needle and emits a visual or audible alarm to indicate that the epidural space has been reached. However, this device also presents the aforementioned problems, since it is a device that corresponds to a control or command box that is operated by a user, which is connected to the needle by wired systems and a pressure sensor connected to the needle lumen. Likewise, in this type of systems it is not possible to prevent the needle from being oriented improperly when it is introduced into the patient, which causes the cutting of tissue and the generation of bruises where the puncture was made. In addition, with the device disclosed in WO 2012/089223, it is not possible to know the orientation of the bevel once the needle is within the epidural space, which would cause the aforementioned problems.
  • WO 92/15256 discloses a device very similar to that disclosed in WO 2012/089223, since it is also a detection device that corresponds to a control or command box that is operated by a user, which is connected to the needle through wired systems and a pressure sensor connected to the needle lumen. Therefore, the device disclosed by WO 92/15256 has the same problems as the device of WO 2012/089223.
  • needles with tactile bevel orientators in the state of the art comprising a notch or flange located on the surface of the needle clamping element, wherein said notch or flange has the function of indicating the orientation of the bevel of the tip of the needle cannula.
  • this type of tactile indicators present several problems, one of the main ones being the difficulty to feel or feel this notch or flange due to the gloves used by anesthesiologists.
  • palpation of the device to locate the notch can cause excessive manipulation thereof causing the above problems.
  • said notch or flange is normally made of the same material as the fastener, which is commonly transparent, it is also difficult to locate said notch or flange visually. Therefore, if these systems are also combined with luminous elements such as those described in the state of the art described above, this further complicates the visual location of the touch marks.
