Description
Technical field
The present invention relates to the lancet device that a kind of combined spinal-epidural anesthesia uses, be specifically related to a kind of two-tube combined puncturing needle, during example operation each for hospital clinical mechanism row, human vertebra and Continual epidural dual-purpose are punctured and injectable drug, belong to technical field of medical instruments.
Background technology
The combined anesthesia pin of medical institutions' use both at home and abroad at present, be widely used in lumbar vertebra and epidural anesthesia, traditional combined anesthesia pin is in epidural needle, insert lumbar vertebra pin, carries out vertebra and the puncture of Continual epidural dual-purpose.Because this product exists some defects, though have the dual-purpose of vertebra and continuous epidural anesthesia, but still there are some problems.Therefore, design a kind of easy and simple to handle, safely and effectively combined anesthesia pin be the common expectation of numerous clinicians and patient.
Summary of the invention
The object of the invention is for above-mentioned the deficiencies in the prior art, a kind of easy and simple to handle, two-tube combined puncturing needle is safely and effectively provided.
The object of the invention is to be achieved through the following technical solutions: two-tube combined puncturing needle, comprise epidural needle and lumbar puncture needle, described epidural needle comprises epidural needle needle stand, anesthetic tube, for placing the epidural needle needle tubing of anesthetic tube, one end of epidural needle needle tubing is connected with epidural needle needle stand; The lumbar puncture needle needle body that described lumbar puncture needle comprises lumbar puncture needle needle stand, is connected with lumbar puncture needle needle stand, it is characterized in that, described lumbar puncture needle also comprises the guid needle for placing lumbar puncture needle needle body, guid needle is connected with the outer wall of epidural needle needle tubing, and is positioned at below epidural needle needle tubing.
Described guid needle afterbody is the arc-shaped structure to downward-extension, and extends to epidural needle needle stand place, and the end of arc-shaped structure is provided with tubaeform targeting port.
Described guid needle intracavity diameter is 1/2nd of epidural needle syringe intracavity diameter.
The other end of described epidural needle needle tubing is the arc-shaped structure upwards extended, and the pin sword of epidural needle is inclined at arc-shaped structure end, and up-bite jaw.
Described guid needle head extends to the arc-shaped structure place of epidural needle needle tubing, and the head of guid needle and the head of epidural needle needle tubing are at a distance of 0.5-1cm.
Described guid needle head is provided with pin sword, and pin sword is inclined at guid needle head end, and gradient is 17 °, down-bite jaw.
The radian of described epidural needle needle tubing arc-shaped structure is 6 °-7 °.
Described epidural needle needle tubing, guid needle are medical stainless steel and make.
Described guid needle and epidural needle needle tubing are by laser spot welding or seamless link.
Described lumbar puncture needle needle stand, epidural needle needle stand front portion are equipped with draw-in groove.
Traditional combined anesthesia pin is in epidural needle, insert lumbar vertebra pin, carry out vertebra and the puncture of Continual epidural dual-purpose, two-tube combined puncturing needle designed by the present invention, the way tool comparing classical joint anesthetic needle has great advantage: in use, epidural needle needle tubing is advanced and will execute pin position, after epidural needle syringe intracavity has put anesthetic tube, in guid needle, lumbar puncture needle needle body is inserted by tubaeform targeting port, toward subarachnoid space injection, effectively can shorten and correct patient body position's time, facilitate the control of doctor to level of anesthesia.
Lumbar puncture needle in the present invention, needs one on outside epidural needle needle tubing have the guiding of the guid needle of tubaeform targeting port and enter subarachnoid space in actual clinical use procedure.The present invention has two different needle tubing pipelines (i.e. epidural needle needle tubing and guid needle), and thus lumbar puncture needle is without the need to the guiding of epidural needle syringe intracavity.Crosspointer (epidural needle and lumbar puncture needle) becomes to be integrated after coordinating, and when the pin basil that anesthetic tube passes epidural needle is spent (the arc-shaped structure place of epidural needle needle tubing), feel is more obvious, and position is accurate, is convenient to implement anesthesia; Guid needle can guide lumbar puncture needle needle body to slide exactly and enter subarachnoid space.Crosspointer combines and operability and safety is improved greatly, effectively reduces the risk of combined anesthesia in operation process.
In the present invention, the arc-shaped structure (angle of guid needle afterbody and epidural needle needle tubing is 15 °) of guid needle extends to epidural needle needle stand place, the end of arc-shaped structure arranges tubaeform targeting port, accurately and effectively lumbar puncture needle needle body can be directed to subarachnoid space.Guid needle intracavity diameter is 1/2nd of epidural needle syringe intracavity diameter, effectively can prevent lumbar puncture needle needle body from spinning in guid needle inner chamber, affect surgical effect.
The other end of epidural needle needle tubing is the arc-shaped structure (radian is 6 °-7 °) upwards extended, and is convenient to anesthetic tube and enters epidural enforcement anesthesia accurately and effectively; Guid needle head extends to the arc-shaped structure place of epidural needle needle tubing, the head of guid needle and the head of epidural needle needle tubing at a distance of 0.5-1cm, like this epidural needle enter correctly execute pin position time, lumbar puncture needle also can accurately be determined to execute pin position; The pin sword of guid needle is inclined at guid needle head end, and gradient is 17 °, down-bite jaw, puts in opposite directions with epidural needle pin sword, is convenient to carry out different anesthesia at two pipelines.Guid needle and epidural needle needle tubing pass through laser spot welding or seamless link, firmly effectively.
Structure of the present invention is simple, and package be compact is coordinated, and can carry out the dual pathways simultaneously put pin, puts caudal block, easy and simple to handle, shortens operating time, effectively improves anaesthetic effect, decrease sufferer misery, improve the safety of product.
