Abstract
The invention discloses a needle cavity seat for a combined anesthesia puncture needle. The needle cavity seat for the combined anesthesia puncture needle comprises a main body. Two ends of the main body are an inlet end of a puncture needle and a fixing end of the needle cavity respectively. A guiding pipe is arranged between the inlet end and the fixing end, and the needle cavity is in butt joint with the guiding pipe. Multiple locating necks are evenly distributed on the outer surface of the main body. Hand-held lugs are detachably assembled on the locating necks. The hand-held lugs are provided with bayonets matched with the necks. By means of the above methods, an original structure of the needle cavity seat is not changed, only by designing the necks, and the hand-held lugs which is capable of adjusting positions based on implementations can be simply added, so that the convenience is brought to a doctor to accurately carry out a puncture anesthetic, the operation risk is lowered, and the anesthesia effect is improved.
Description
Technical field
The present invention relates to medical instruments field, particularly relate to a kind of combined anesthesia puncture needle pin chamber seat.
Background technology
The combined anesthesia puncture needle that present stage uses is pin in pin, only has the anesthetic tube pin that independent in pin chamber.
In use, independent anesthetic tube completes an anesthesia injection needs about 10 minutes, and anesthesia duration is longer.When run into compared with during major operation or more urgent emergency surgical operation time, consume too many preoperative preparation time and operating time, have a strong impact on the success rate of emergency surgical operation.
In addition, existing puncture needle, when injecting anesthetic, is not supplied to the structure that doctor grips easily, and being difficult to ensure precision in the process of anesthesia injection, is very large adjustment to doctor, for operation brings very large risk yet.
Summary of the invention
The technical problem that the present invention mainly solves is to provide one and doctor can be facilitated to grip puncture needle, contributes to the combined anesthesia puncture needle pin chamber seat that doctor precisely implements.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of combined anesthesia puncture needle pin chamber seat, comprise: body, body two ends are respectively the arrival end of puncture needle and the stiff end in pin chamber, be provided with a guiding tube between described arrival end and stiff end, described pin chamber is docked with described guiding tube; Described body outer surface is evenly provided with many grades of locating grooves, detachablely on locating groove is equipped with hand-held earflap, described hand-held earflap offers the bayonet socket with pocket matches.
In a preferred embodiment of the present invention, described body is rectangular body or cylindrical body.
In a preferred embodiment of the present invention, described guiding tube is conical guiding tube, and vertex of a cone end is connected with pin chamber.
In a preferred embodiment of the present invention, when body is rectangular body, the relative dual-side of rectangular body is provided with locating groove.
In a preferred embodiment of the present invention, the drops that the cross section in described pin chamber is big up and small down.
The invention has the beneficial effects as follows: combined anesthesia puncture needle pin chamber of the present invention seat does not change the structure of original pin chamber seat, design by means of only draw-in groove, can simply increase can according to the hand-held earflap of performance adjusting position, contribute to doctor and precisely implement puncture anesthesia, reduce operation risk, improve anaesthetic effect.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of combined anesthesia puncture needle pin chamber of the present invention seat one preferred embodiment;
Fig. 2 is the structural representation of hand-held earflap in the seat of the puncture needle pin of combined anesthesia shown in Fig. 1 chamber;
In accompanying drawing, the labelling of each parts is as follows: 1, body, and 2, pin chamber, 3, guiding tube, 4, locating groove, 5, hand-held earflap, 6, bayonet socket.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of combined anesthesia puncture needle pin chamber seat, comprising: body 1, body 1 two ends are respectively the arrival end of puncture needle and the stiff end in pin chamber 2.The drops that the cross section in described pin chamber 2 is big up and small down.
Described body 1 is rectangular body or cylindrical body.
Be provided with a guiding tube 3 between described arrival end and stiff end, described pin chamber 2 is docked with described guiding tube 3; Described guiding tube 3 is conical guiding tube 3, and vertex of a cone end is connected with pin chamber 2.
Described body 1 outer surface is evenly provided with many grades of locating grooves 4, and when body 1 is rectangular body, the relative dual-side of rectangular body is provided with locating groove 4.
Detachablely on locating groove 4 be equipped with hand-held earflap 5, described hand-held earflap 5 offer the bayonet socket 6 with pocket matches, as shown in Figure 2.
Bayonet socket 6 is stuck in the locating groove 4 of both sides, and operator can keep balance by controlling hand-held earflap 5, guarantees the success rate of anesthetic puncture.
Also can according to different surgery situation, regulate the position of hand-held earflap 5, operator can attempt the operating experience on each gear, finds optimum position and performs the operation.
Combined anesthesia puncture needle pin chamber of the present invention seat does not change the structure of original pin chamber seat, by means of only draw-in groove design, simply can increase and according to the hand-held earflap 5 of performance adjusting position, doctor can be contributed to and precisely implement puncture anesthesia, reduce operation risk, improve anaesthetic effect.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
