Problems solved by technology

[0006] The puncture needle for spinal anesthesia is relatively thin, so the spinal anesthesia catheter placed through the inner cavity of the lumbar anesthesia needle has to be designed very thin, so it is very difficult to inject drugs through the thin and long spinal anesthesia catheter
The thin and long spinal anesthesia catheter is difficult to produce, and the thin and long spinal anesthesia catheter is easily discounted, resulting in blockage of the lumen and inability to inject drugs
The spinal anesthesia catheter is too thin and too long to break easily, causing foreign matter to remain in the body

Embodiment 1

[0029] As shown in Figure 1, in one embodiment of the present invention, the spinal anesthesia catheter 10 of the present invention is a flexible rubber tube, and the tube body is a hollow tube, and one end of the tube body is set as a thin end 102, and the length of the thin end is It is the part 3cm away from the tip, and the tip of the thin end is set as a "?" It is 0.6mm, and the total length of the tube body is 90cm. Further, the pipe body is spiral, and the plane where the "?"-shaped hook 103 is located is perpendicular to the plane where the spiral pipe body is located. The hook shape has a diameter of 5mm and a length of 7mm.

[0030] The spinal anesthesia device of the present invention includes a spinal anesthesia puncture needle, a guide wire, and a spinal anesthesia catheter. As shown in Figure 3, the guide wire includes a tough guide wire 50 and a sleeve 40, the guide wire One end is set to a rounded tip, and the tip is also set to a "?" The planes where the ma...

Embodiment 2

[0034]As shown in Figure 2, in another embodiment of the present invention, the spinal anesthesia catheter 20 is a flexible rubber tube made of medical plastic, one end of the tube body is set as a thin end 2011, and the end of the thin end is set as For the "?" shaped hook 2012, the outer diameter of the thin end is 0.5 mm, the inner diameter is 0.3 mm, the outer diameter of the rest of the tube body is 0.9 mm, the inner diameter is 0.7 mm, and the overall length of the tube body is 100 cm. The plane where the "?"-shaped hook 2012 is located is perpendicular to the plane where the spiral tubular body is located. Further, the tube body is spiral, and the tube body is divided into two sections, the short section 201 includes a thin end 2011, and the length of this section is 30 cm. The long section 202 is relatively thick, and the two sections of pipe bodies can be connected together, and the total length of the spinal anesthesia catheter is 100cm. The hook shape has a diamete...

Embodiment 3

[0039] As shown in FIG. 6 , it is a schematic structural view of a spinal anesthesia catheter 60 in another embodiment of the present invention. Its structure is similar to that of the second middle spinal anesthesia catheter. The difference lies in the shape of the crotch 6012 at the thin end of the tube body. , in this embodiment, the curvature of the hook 6012 is small, and its shape is roughly an elliptical arc. The diameter of the hook is 3mm, and the length of the hook is 4mm.

[0040] The outer diameter of the thin end is 0.45 mm, the inner diameter is 0.25 mm, and the outer diameter of the rest of the tube body is 0.85 mm, and the inner diameter is 0.65 mm. The length of the short section 601 is 35cm, and the total length of the catheter for spinal anesthesia is 93cm.

[0041] The structure of the guide wire in this example is as described in Example 1, but the length of the tough guide wire is 45 cm, and the total length of the cannula is slightly longer than the leng...

Abstract

The invention relates to a medical appliance, in particular to a lumbar anesthesia duct and a lumbar anesthesia device which has the lumbar anesthesia duct. The lumbar anesthesia duct of the invention has a thin end at one section, the rest sections are thicker, the pointed end of the thin end is arranged in a 'i' shape hook, which is convenient for the lumbar anesthesia duct to enter an subarachnoid space without injuring nerves, further, the lumbar anesthesia duct is arranged in a two-section type, which is convenient for users to operate. The lumbar anesthesia device of the invention comprises lumbar anesthesia puncture needles, the lumbar anesthesia duct, and a guiding silk which comprises a tough godet with a 'i' shape hook pointed end, and a cannula is arranged outside a filament, which can be convenient for the tough godet to lead-in an inner cavity of a lumbar anesthesia needle.

Description

technical field [0001] The invention relates to a medical appliance, in particular to a spinal anesthesia catheter and a spinal anesthesia device containing the spinal anesthesia catheter. Background technique [0002] The spine is the backbone of the human body, and it is also the main channel and protective cover for the transmission of nerve information. The spine, as the central part of the human body, is structurally located in the center of the body, coordinating and controlling the activities of the head and limbs. Nerves from each pair of intervertebral foramina control sensory and motor functions throughout the body. When the human body is sick and needs to perform surgery or perform diagnostic inspection operations, in order to reduce the pain of the patient, ensure the safety of the patient, and create good surgical conditions, it is necessary to anesthetize the patient. Intraspinal anesthesia is an important way of anesthesia. It injects local anesthetics into ...
