Abstract
The invention discloses a double-rail type anaesthesia combined trocar. The double-rail type anaesthesia combined trocar needle comprises a needle seat and a first needle body, wherein the needle seat is communicated with the first needle body; the first needle body is internally provided with a first needle hole which can be penetrated by an anaesthesia conduit; one side of the needle seat is provided with a side seat; one side of the first needle body is fixed with a second needle body; the second needle body is internally provided with a second needle hole which can be penetrated by a lumbar spinal needle; and the second needle hole is communicated with the side seat. According to the double-rail type anaesthesia combined trocar needle, as the side seat is integrally formed on the needle seat, the anaesthesia conduit enters a human body through the needle seat along the first needle body, the lumbar spinal needle can enter the human body through the side seat along the second needle body at the same time, and the mutual mixing of different injected liquid medicines, which is caused due to the fact that the anaesthesia conduit and the lumbar spinal needle simultaneously enter a same area, is effectively prevented by adopting a double-rail type structure; and the double-rail type anaesthesia combined trocar needle disclosed by the invention has the advantages of high accuracy, increased transfusion speed, safety, reliability, simple structure, convenience for manufacturing and convenience, accuracy and fastness for operation realized by operators.
Description
Technical field
The novel medical instruments field that relates to of the present invention particularly relates to a kind of double-rail anesthesia associating trocar.
Background technology
At present, the associating Subarachnoid Epidural Anesthesia has been concentrated the advantage of lumbar anesthesia and epidural anesthesia, and is rapid-action, and the flesh pine has obtained deep research and widely application both at home and abroad fully in the recent decade again.But traditional thorn of threading a needle is " pin in the pin " type, its anesthesia is sequentially for after thrusting epidural space with combined spinal-epidural anesthesia puncture needle first, again spinal needle (lumbar puncture needle) is thrust subarachnoid space through the combined spinal-epidural anesthesia puncture needle inner chamber and implement lumbar anesthesia, then withdraw from spinal needle and carry out again the dura mater Puncture Tube, stand up and regulate the lumbar anesthesia plane.
When this process may occur inserting anesthetic tube, conduit entered subarachnoid space along former lumbar vertebra pin at the pinprick that spinal dura mater stays.Symptoms such as high position sensation and nervus motorius retardance may appear in this situation, and is mishandling even can affect patient's life.
Simultaneously, such puncture needle structure is complicated, and processing difficulties can cause larger wound in the practical application, and wayward interspersed position.
Invent novel content
The technical problem that Novel main of the present invention will solve provides a kind of double-rail simple in structure, simple to operate, easy to process, that use safety and anaesthetizes the associating trocar.
For solving the problems of the technologies described above, a technical scheme of the novel employing of the present invention is: a kind of double-rail anesthesia associating trocar is provided, comprise needle stand and the first needle body, described needle stand is communicated with the first needle body, offer in described the first needle body and can intert the first pin hole of anesthetic tube, described needle stand one side is provided with the side seat, and described the first needle body one side is fixed with the second needle body, offer in described the second needle body and can intert the second pin hole of lumbar puncture needle, described the second pin hole is communicated with the side seat.
In the novel preferred embodiment of the present invention, described side seat and needle stand are one-body molded.
In the novel preferred embodiment of the present invention, the top end face tilt of described side seat arranges.
In the novel preferred embodiment of the present invention, the diameter of described the second needle body is less than the diameter of the first needle body.
In the novel preferred embodiment of the present invention, the length of described the second needle body is less than the length of the first needle body.
In the novel preferred embodiment of the present invention, described the second needle body and the first needle body are bonding.
In the novel preferred embodiment of the present invention, the liquid outlet of described the second needle body is side cut opening.
In the novel preferred embodiment of the present invention, be fixed with two installing plates on the described needle stand, described installing plate is symmetrical arranged.
In the novel preferred embodiment of the present invention, described installing plate is fixed in the groove of needle stand.
In the novel preferred embodiment of the present invention, the needle tip of described the first needle body is provided with and makes the pin mouth to the curved bend pars convoluta of lopsidedness.
The novel beneficial effect of the present invention is: the novel double-rail of the present invention anesthesia associating trocar has a side seat owing to one-body molded on needle stand, anesthetic tube enters human body by needle stand along the first needle body, lumbar puncture needle can enter human body along the second needle body simultaneously by the side seat, adopt the double-rail structure effectively to avoid anesthetic tube and lumbar puncture needle to enter simultaneously the same area, cause different injection medicinal liquids mutually to mix, precision is high, improved transfusion speed, safe and reliable, and this double-rail anesthesia associating trocar is simple in structure, easy to make, operator can make things convenient for, accurately, realize rapidly operation.
Description of drawings

Fig. 2 is the left view of Fig. 1;
Fig. 3 is the top view of Fig. 1;
The labelling of each parts is as follows in the accompanying drawing: 1, needle stand, the 2, first needle body, 3, the side seat, the 4, second needle body, 5, anesthetic tube imports and exports, 6, lumbar puncture needle imports and exports, 7, installing plate, 8, the curved bend pars convoluta.
The specific embodiment
Below in conjunction with accompanying drawing the novel preferred embodiment of the present invention is described in detail, thereby so that the novel advantage of the present invention and feature can be easier to be it will be appreciated by those skilled in the art that the novel protection domain of the present invention is made more explicit defining.
See also Fig. 1 to Fig. 3, new embodiment of the present invention comprises:
A kind of double-rail anesthesia associating trocar, comprise needle stand 1 and the first needle body 2, described needle stand 1 is communicated with the first needle body 2, offer in described the first needle body 2 and can intert the first pin hole of anesthetic tube, described needle stand 1 one sides are provided with side seat 3, described the first needle body 2 one sides are fixed with the second needle body 4, offer in described the second needle body 4 to intert the second pin hole of lumbar puncture needle, and described the second pin hole is communicated with side seat 3.
Described side seat 3 is one-body molded with needle stand 1, and the top end face tilt of described side seat 3 arranges, and is convenient to the lumbar puncture needle of pegging graft, and different from installing/dismounting formula needle stand in the past, structure is more simple, processes more conveniently, and not fragile, uses convenient.
