FIG. 1 is a schematic view of a guide plate for lumbar anesthesia puncture according to an embodiment of the present utility model.
Fig. 2 is a schematic illustration of a lancing operation in accordance with an embodiment of the present utility model.
Figure number: puncture guide 101, puncture channel slot 102, needle insertion lining 103, fixing base plate 104, mounting groove 105, limit ring 106, and groove 107.
Detailed Description
The present utility model will be described in further detail by way of examples with reference to the accompanying drawings, which are illustrative of the present utility model and not limited to the following examples.
Referring to fig. 1-2, a guide plate for lumbar anesthesia puncture according to the present embodiment includes a puncture guide plate 101, the puncture guide plate 101 is provided with a puncture channel slot 102, the puncture channel slot 102 is adapted with a needle insertion liner 103, and the needle insertion liner 103 is provided with multiple types, so that the needle insertion liner 103 is adapted to the diameters of the epidural puncture needles of multiple types.
The present embodiment relates to a guide plate for lumbar anesthesia puncture, which is relatively convenient to use direct positioning puncture, and the arrangement of the puncture channel slot 102 is helpful to ensure a good puncture path, and is not easy to shift. There are 4 types of more suitable puncture needles. Touhg-type inclined plane, cranford-type inclined plane; the Whitart inclined plane type venous indwelling needle is characterized in that when the Whitart inclined plane type venous indwelling needle is selected, a proper type and thickness of the puncture needle are generally selected according to the age, the body type and the like of a patient to perform lumbar anesthesia puncture, the puncture channel slot 102 of the product is provided with a needle insertion lining 103, by selecting different needle insertion linings 103, the proper type and thickness of the puncture needle can be matched according to the age, the body type and the like of an actual patient,
in this embodiment, the fixing base plate 104 is further provided with an installation groove 105 adapted to be fastened to the puncture guide plate 101, and a protruding stop ring 106 is disposed at the bottom of the installation groove 105, in this embodiment, since the operation position of the puncture guide plate 101 is smaller, and if the puncture guide plate 101 is positioned, for a patient with a larger body size or loose skin, the patient easily causes displacement of the puncture guide plate 101 during the puncture process, so that the size of the fixing base plate 104 can be selected according to the actual body size and shape of the patient, the fixing base plate 104 is used for increasing the contact area with the skin, ensuring the stability of the puncture guide plate 101 during the puncture process, and specifically, the fixing base plate 104 is fixed on the skin by adopting a 3M double-sided adhesive film.
In this embodiment, in order to more accurately determine the puncture path, ensure safety, CT or MRI scan may be performed on the lumbar vertebra of the patient in advance, in the scan, the lumbar vertebra portion of the patient is attached with, for example, a metal patch, an initial position is determined, a safe puncture position is determined in an obtained image, a distance L between the initial position and the puncture position is calculated, in the puncture process, the puncture position of the puncture guide plate 101 is adapted to the puncture channel and the puncture position by marking the puncture position of the metal patch with the distance L, so that the puncture safety is effectively ensured.
In this embodiment, the needle insertion liner 103 includes a threaded connection portion and a puncture channel portion, the threaded connection portion is in threaded fit with an outer wall surface of the puncture channel slot 102, the puncture channel portion is slidably disposed in the puncture channel portion, a groove 107 adapted to a needle limit portion is disposed at a head end of the needle insertion liner 103, when the above CT or MRI scan image analysis path is performed, a substantial puncture depth D is already known, a distance D 'between an end of the needle insertion liner 103 and an end of the puncture channel is only required to be adjusted through threads, and the distance D' =d-D is marked on an outer wall surface of the needle insertion liner 103 for adapting the puncture distance, so that the adjustment and the grasping are facilitated, and the puncture distance is prevented from being insufficient (reaching an epidural space) or being too deep (puncturing would puncture a dura mater, and leakage of cerebrospinal fluid occurs).
The foregoing description of the utility model is merely exemplary of the utility model. Those skilled in the art may make various modifications or additions to the described embodiments or substitutions, without departing from the scope of the utility model as defined in the accompanying claims.
