Abstract
The utility model discloses a locator for positioning in puncturing of intracranial hematoma or a human body, which comprises an adhesive layer, an inner gauze layer, an outer gauze layer and a plastic cylinder. The plastic cylinder is buried between the two gauze layers, the inner gauze layer is bonded on the adhesive layer, the outer gauze layer is uniformly provided with parallel mark lines along the x axis and the y axis, and thus a square grid is formed; and the plastic cylinder is made of medical polyurethane or other X-ray-impermeable materials, adopts a solid or hollow cylinder and is filled with purified water. By adopting the locator, accurate positioning and direction fixing can be achieved. The locator is simple and practical, the probability of further bleeding can be reduced, the effect of hematoma drainage can be improved, the CT (computed tomography) scanning frequency can be decreased, and the radiation exposure and complications can be reduced.
Description
Technical field
This utility model belongs to medical instruments field, is specifically related to the localizer of a kind of intracranial hematoma puncture or body puncture location usefulness.
Background technology
No matter be intracerebral hematoma microtrauma puncture external drainage art or body puncture, a very important link is located exactly, comprises deciding point of puncture, puncture direction and the degree of depth.Localization method mainly contains label positioning mode, the accurate positioning mode of stereotactic apparatus, neurosurgery navigation system and the virtual positioning mode of spiral CT three-D post processing of image.At present most widely used still label body surface location, this is for most of basic hospitals, and is simple and practical.But mostly localizer is that doctor oneself makes by hand, useful waste and old contrast agent conduit, also bonding jumper or wiry carefully such as useful paper clip does not have unified standard.Though spacing is chosen as 1cm mostly, makes by hand and often owe accurate.And exhausted contrast agent conduit is disposable medical supplies, may cause cross infection.In addition, metal material such as paper clip also can produce radial pseudo-shadow in CT scan.
Chinese patent 200810159661.3 discloses a kind of CT puncture locator, and this localizer comprises adhesive plaster pad and conduit, and the adhesive plaster pad is made up of two identical common adhesive plasters of size, and the two glue face is relative, is bonded together, and the centre is a conduit isometric, equidistant arrangement.This localizer is placed the body surface projection place of patient's pathological changes, under the CT guiding, reach pinpoint purpose during puncture.Catheter device costs an arm and a leg, if with new conduit, can increase the weight of patient's financial burden, this place uses is used disposable conduit once, through oneself cutting out, makes stickup by hand and forms, might cause cross infection, make spacing 1cm by hand and owe accurate.
Summary of the invention
(1) goal of the invention
At the defective that prior art exists, this utility model aims to provide a kind of simple in structure, low price, the more convenient localizer of use.
(2) technical scheme
For achieving the above object, this utility model provides following technical scheme.
A kind of localizer comprises adhesive layer, internal layer gauze, outer gauze and plastic cylinder, and plastic cylinder is embedded between the inside and outside layer gauze, and the internal layer gauze sticks on the adhesive layer.Key is that outer gauze is provided with parallel, equally distributed markings along X-axis, Y direction, forms square net; Plastic cylinder uses the material of medical grade polyurethane or other X-ray opaques, or is solid cylinder, or is hollow and the cylinder that is full of pure water, arranges along the markings of outer gauze Y direction.
As a kind of prioritization scheme, the circular hole that it is 2-3mm that four quadrants in the cross point of outer gauze markings are provided with allo with it radius, circular hole runs through outer gauze, internal layer gauze and adhesive layer.
(3) invention effect
It is accurate that the localizer that this utility model provides is decided direction, simple and practical, can reduce hemorrhage probability again, improves the effect of hematoma drain, reduces the CT scan number of times, reduces radioactive radiation and complication.

Wherein, 1, internal layer gauze; 2, outer gauze; 3, plastic cylinder; 4, adhesive layer; 5, circular hole.
Embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is further elaborated.
As shown in Figure 1, 2, 3, a kind of CT puncture locator comprises adhesive layer 4, internal layer gauze 1, outer gauze 2 and plastic cylinder 3.Diameter is 2mm, high for the plastic cylinder 3 of 9cm is embedded in 1 on the internal layer gauze, external application skin gauze 2.Internal layer gauze 1 sticks on the adhesive layer 4.Be marked with the grid that length and width is 1cm at internal layer yarn 1, arrange plastic cylinder 2 along the vertical markings of grid (Y direction).Plastic cylinder 2 intersects with lateral marker line (X-axis), the circular hole 5 that to be provided with allo with it radius in four quadrants in cross point are established be 2mm, and circular hole 5 runs through outer gauze 2, internal layer gauze 1 and adhesive layer 4.The material of plastic cylinder 3 is the material of medical grade polyurethane (TPU) or other X-ray opaques.
During use, at first select the abscissa line of Y=-4 and the OM line of CT or the horizontal line of true baseline position to coincide, the vertical line of Y-axis and CT coincide, and sticks on patient's head; Determine hemorrhage maximum aspect according to CT, determine the coordinate of Y-axis, determine the coordinate of X-axis again by plastic cylinder 3, carry out mark by the circular hole 5 that the cross point is other; Determine the puncture direction according to the CT image at last, puncture needle can puncture by circular hole 5.
As a kind of localizer that is useful for the nuclear magnetic resonance, NMR puncture, the same embodiment of its structure, difference is that the two ends 1cm of plastic cylinder 3 is solid, and middle 7cm inside is hollow, and wall thickness is the 1mm diameter, and hollow space is full of pure water.
Claims (3)
1. localizer, comprise adhesive layer (4), internal layer gauze (1), outer gauze (2) and plastic cylinder (3), plastic cylinder (3) is embedded between the inside and outside layer gauze (1,2), internal layer gauze (1) sticks on the adhesive layer (4), it is characterized in that: described outer gauze (2) is provided with parallel, equally distributed markings along X-axis, Y direction, forms square net; Plastic cylinder (3) uses the material of medical grade polyurethane or other X-ray opaques, arranges along the markings of outer gauze (2) Y direction.
