Abstract
A kind of children are with fine adjustment type combined anesthesia trocar, including epidural needle and spinal needle, and the backshank of epidural needle is provided with epidural needle handheld terminal；The backshank of spinal needle is provided with spinal needle handheld terminal；Epidural needle handheld terminal is provided with epidural needle joining section；Spinal needle handheld terminal is provided with spinal needle joining section；Endoporus of the spinal needle through epidural needle, its spinal needle joining section are threadedly coupled with epidural needle joining section.Lumbar anesthesia Aculeata of the present invention and epidural needle afterbody joining place, it is connected by screw thread, so, spinal needle is relatively fixed stable with epidural needle, ensure that lumbar anesthesia medicinal liquid, in injection, solves not fixing due to spinal needle so that spinal needle is moved forward and backward during injection anaesthetic, can not guarantee that calculated medicinal liquid is all on board, so as to have impact on the problem of anaesthetic effect.The design of the present invention ensure that the stable and quality of anesthesia of anaesthesia process.
Description
Technical field
The present invention relates to medical articles for use field, specifically a kind of children are with fine adjustment type combined anesthesia trocar.
Background technology
Spinal needle front end exceeds epidural needle 1CM, that is to say, that：Two needle points, two backshanks when at a distance of 1CM are only linking, but, the epidural space of children is spaced without 1CM width with subarachnoid space, this there is the shortcoming that spinal needle cannot be fixed, so that Anesthetist is susceptible to the movable of spinal needle when anesthetic liquid medicine is injected, can not guarantee that calculated medicinal liquid is all on board, so as to have impact on anaesthetic effect.
The content of the invention
In sum, it is an object of the invention to provide a kind of children are with fine adjustment type combined anesthesia trocar.
The purpose of the present invention is realized by following technology：
A kind of children are with fine adjustment type combined anesthesia trocar, including epidural needle and spinal needle, and the backshank of epidural needle is provided with epidural needle handheld terminal；The backshank of spinal needle is provided with spinal needle handheld terminal；Epidural needle handheld terminal is provided with epidural needle joining section；Spinal needle handheld terminal is provided with spinal needle joining section；Endoporus of the spinal needle through epidural needle, its spinal needle joining section are threadedly coupled with epidural needle joining section.
Above-mentioned epidural needle joining section is hollow circuit cylinder cylinder, and its inwall is provided with female thread.
Above-mentioned spinal needle joining section is cylinder, and which is externally provided with external screw thread.
Advantages of the present invention and beneficial effect：
Lumbar anesthesia Aculeata of the present invention and epidural needle afterbody joining place, it is connected by screw thread, so, spinal needle is relatively fixed stable with epidural needle, ensure that lumbar anesthesia medicinal liquid, in injection, solves not fixing due to spinal needle so that spinal needle is moved forward and backward during injection anaesthetic, can not guarantee that calculated medicinal liquid is all on board, so as to have impact on the problem of anaesthetic effect.
The design of the present invention ensure that the stable and quality of anesthesia of anaesthesia process.
Description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is epidural needle schematic diagram in the present invention.
Fig. 3 is spinal needle schematic diagram in the present invention.
In figure：1- epidural needle handheld terminal 2- epidural needle 3- spinal needle handheld terminal 4- spinal needle 11- epidural needle joining section 21- spinal needle joining section 22- syringe interfaces.
Specific embodiment
The present invention will be further described below in conjunction with the accompanying drawings：
As shown in Figure 1, 2, 3, a kind of children are with fine adjustment type combined anesthesia trocar, including epidural needle 3 and spinal needle 4, and 3 backshank of the epidural needle is provided with epidural needle handheld terminal 1；4 backshank of spinal needle is provided with spinal needle handheld terminal 2；Epidural needle handheld terminal 1 is provided with epidural needle joining section 11；Spinal needle handheld terminal 2 is provided with spinal needle joining section 21；Endoporus of the spinal needle 4 through epidural needle 2, spinal needle joining section 21 are connected with epidural needle joining section 11；Epidural needle joining section 11 is hollow circuit cylinder cylinder, and its inwall is provided with female thread；Spinal needle joining section 21 is cylinder, and which is externally provided with external screw thread.
Embodiment
Under the premise of guaranteeing that epidural puncture is successful, the nook closing member in epidural needle 3 is extracted, then spinal needle 4 is injected from the pin hole of epidural needle 3, extracted the nook closing member of spinal needle 4, syringe is connect by syringe interface 22, push note lumbar anesthesia medicinal liquid, to reach anaesthetic effect.
The epidural needle joining section 11 of the epidural needle handheld terminal 1 of epidural needle 3 is threaded connection with the spinal needle joining section 21 of the spinal needle handheld terminal 2 of spinal needle 4, can more accurate children epidural space and subarachnoid space between distance of injection.
