Abstract
The utility model relates to a minimally invasive epidural puncture needle, which is characterized in that a 9G lumbar puncture needle is used as an embryonic body, and the total length of a needle stem is 8cm; the needle stem is engraved with scales taking 1cm as a unit, and the tip of the needle is bluntly ground; and the inclined surface is arranged at an angle of 45 degrees. In the puncture process, the needle stem has certain hardness, so the utility model is not easy to bend, has little tissue trauma, few complications, obvious layering sense of puncture, easy control of depth, simple operation and greatly improved safety, is suitable for the epidural puncture drug injection, and treats lumbocrural pain caused by intraspinal lesions.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, a kind of specifically Wicresoft cavum epidural puncture pin.
Background technology
We know that the cavum epidural puncture injection is clinical modal pain therapy means, and at present multiselect is with two kinds of model puncture needles.A kind of is that 18G cavum epidural puncture pin is thicker, and its front end is a spoonful shape circle dull face, in piercing process, easily cut off ligament, big to tissue injury, leave over lumbago and backache and local tenderness incidence rate is higher, easily cause blood vessel injury, cause epidural hematoma, the compression of spinal cord symptom occurs.The another kind of 7G lumbar puncture needle that adopts punctures, though tissue injury is little, lumbago and backache and local tenderness incidence rate are lower, the melancholy of acomia stiff film exocoel hematoma, but the pin stalk is thinner, flexible during use, and needle point is sharper, the breakthrough sense that enters epidural space is not obvious, and easily punctures spinal dura mater, has increased the difficulty and the unsafe factor of operation.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of simple in structure, easy to use, and the degree of depth is easy to control, and is easy and simple to handle, the disposable use Wicresoft cavum epidural puncture pin that safety improves greatly.
The technical scheme in the invention for solving the above technical problem is: a kind of Wicresoft cavum epidural puncture pin is characterized in that: it is young body with the 9G lumbar puncture needle, its pin stalk length overall 8cm, and it is that unit is carved with scale that the pin stalk is gone up with 1cm, the blunt mill of needle point, the inclined-plane is 45.
This utility model is young body with the 9G lumbar puncture needle, its pin stalk length overall 8cm, and it is that unit is carved with scale that the pin stalk is gone up with 1cm, the blunt mill of needle point, the inclined-plane is 45.The contrast prior art, this utility model pin stalk in piercing process has certain rigidity, not flexible, and tissue injury is little, and complication is few, the stereovision of puncture is obvious, the degree of depth is easy to control, and is easy and simple to handle, and safety improves greatly, be applicable to the cavum epidural puncture injection, the lumbago and skelalgia that pathological changes causes in the treatment canalis spinalis.
Description of drawings
Below in conjunction with accompanying drawing this utility model is described further.
Fig. 1 is a structural representation of the present utility model.
1. pintles among the figure, 2. pin stalk, 3. needle point.
The specific embodiment
As can be seen from Figure 1, a kind of Wicresoft of this utility model cavum epidural puncture pin, it is young body with the 9G lumbar puncture needle, comprises pintle 1, pin stalk 2, needle point 3 three parts.The puncture needle pin obstructs 2 length overall 8cm, and it is that unit is carved with scale that the pin stalk is gone up with 1cm, needle point 1 blunt mill, and the inclined-plane is 45.Pintle 1 can directly connect disposable needle tubing.
This utility model is young body with the 9G lumbar puncture needle, its pin stalk length overall 8cm, and it is that unit is carved with scale that the pin stalk is gone up with 1cm, the blunt mill of needle point, the inclined-plane is 45.The pin stalk has certain rigidity in piercing process, and is not flexible, and tissue injury is little, and complication is few, the stereovision of puncture is obvious, and the degree of depth is easy to control, and is easy and simple to handle, safety improves greatly, is applicable to the cavum epidural puncture injection, the lumbago and skelalgia that pathological changes causes in the treatment canalis spinalis.
