Abstract
The invention discloses a combined spinal-epidural anesthesia puncture needle, comprising a puncture needle tube (1), an epidural anesthesia canal and a spinal anesthesia puncture needle, characterized in that the puncture needle tube (1) is provided with an epidural anesthesia canal introducing tube cavity (2) in the middle, a spinal anesthesia puncture needle introducing tube cavity (3) in the rear. According to the invention, the combined spinal-epidural anesthesia puncture needle tube is punctured in the spinal space, and the epidural anesthesia canal introduced in the epidural anesthesia canal introducing tube cavity is introduced in the epidural cavity, when the epidural anesthesia canal is in the right position, the spinal anesthesia canal introduced in the spinal anesthesia puncture needle introducing tube cavity is punctured in the spinal-epidural subarachnoid space to administrate anesthetics for the smooth operation.
Description
One, technical field:
The present invention relates to a kind of medical apparatus and instruments, especially for operating combined spinal-epidural anesthesia puncture needle below the waist and belly.
Two, background technology:
At present, the known following operating combined spinal-epidural anesthesia puncture needle of waist and belly that is used for, it comprises puncture needle tubing, segmental epidural catheter and lumbar anesthesia puncture needle, the puncture needle pipe has a tube chamber, earlier the puncture needle tubing is thrust the patient's waist intervertebral space during operation, then the lumbar anesthesia puncture needle is inserted the tube chamber of puncture needle tubing, the lumbar anesthesia lancet puncture is gone into subarachnoid space inject anaesthetic, after extracting the lumbar anesthesia puncture needle, again segmental epidural catheter is inserted the tube chamber of puncture needle tubing, insert patient's stiffness of the waist film exocoel.The weak point of this structure is when segmental epidural catheter can't be put into, but the anaesthetic onset that the lumbar anesthesia puncture needle injects causes the epidural anesthesia failure.
Three, summary of the invention:
The object of the present invention is to provide a kind of combined spinal-epidural anesthesia puncture needle, to overcome the deficiency of known technology.
The present invention is achieved in that a kind of combined spinal-epidural anesthesia puncture needle, it comprises puncture needle tubing (1), segmental epidural catheter and lumbar anesthesia puncture needle, its special character is that having segmental epidural catheter at the middle part of puncture needle tubing (1) inserts tube chamber (2), has the lumbar anesthesia puncture needle and insert tube chamber (3) on the tube wall at puncture needle tubing (1) rear portion.
Combined spinal-epidural anesthesia puncture needle of the present invention, when operation, the puncture needle tubing is thrust the patient's waist intervertebral space, again the segmental epidural catheter of inserting at the puncture needle tubing is inserted intraluminal segmental epidural catheter and inserted epidural space, when correct position that segmental epidural catheter is put into, insert intraluminal lumbar anesthesia puncture needle at the lumbar anesthesia puncture needle of puncture needle tubing and thrust stiffness of the waist subarachnoid space and inject anaesthetic inserting again, operation is carried out smoothly.
Four, description of drawings:
Fig. 1: a kind of structural representation of the present invention.
The A of Fig. 2: Fig. 1-A cutaway view.
Five, the specific embodiment:
The invention will be further described in conjunction with the specific embodiment with reference to accompanying drawing.
The specific embodiment 1, accompanying drawing has provided a kind of concrete structure of the present invention, consult Fig. 1 and Fig. 2, a kind of combined spinal-epidural anesthesia puncture needle, it comprises puncture needle tubing (1), segmental epidural catheter and lumbar anesthesia puncture needle, have segmental epidural catheter at the middle part of puncture needle tubing (1) and insert tube chamber (2), on the tube wall at puncture needle tubing (1) rear portion, have the lumbar anesthesia puncture needle and insert tube chamber (3).
Combined spinal-epidural anesthesia puncture needle of the present invention, when operation, the puncture needle tubing is thrust the patient's waist intervertebral space, again the segmental epidural catheter of inserting at the puncture needle tubing is inserted intraluminal segmental epidural catheter and inserted epidural space, when correct position that segmental epidural catheter is put into, insert intraluminal lumbar anesthesia puncture needle at the lumbar anesthesia puncture needle of puncture needle tubing and thrust stiffness of the waist subarachnoid space and inject anaesthetic inserting again, operation is carried out smoothly.
Claims (1)
1, a kind of combined spinal-epidural anesthesia puncture needle, it comprises puncture needle tubing (1), segmental epidural catheter and lumbar anesthesia puncture needle, it is characterized in that having segmental epidural catheter at the middle part of puncture needle tubing (1) inserts tube chamber (2), on the tube wall at puncture needle tubing (1) rear portion, have the lumbar anesthesia puncture needle and insert tube chamber (3).
