Abstract
The utility model discloses an integrated low-trauma bone marrow puncture needle which comprises a needle sleeve and a needle core penetrating in the needle sleeve. An injection channel is formed in the middle of the needle core, the tail end of the needle core is connected with an injector, and a hand shank is fixedly connected outside the needle sleeve. The integrated low-trauma bone marrow puncture needle can simultaneously inject a narcotic through the needle core to the puncture portion through the injector in the puncture process, the narcotic is accurately injected, a multi-point periosteum narcosis is not needed, after the bone marrow is punctured, the injector and the needle core are taken out, an injector for extracting the bone marrow is placed in the needle sleeve, and the bone marrow can be extracted. Only one-time puncture is needed in the whole process of extracting the bone marrow, tissue damage and bleeding risks caused by repeated puncture are avoided, trauma caused by the puncture is reduced to the maximum, and pains of a patient are relieved. According to the structure, the situation that the diameter of a puncture portion of the needle sleeve of the integrated low-trauma bone marrow puncture needle is increased due to changes of the needle core structure does not happen, and the advantages of the novel integrated low-trauma bone marrow puncture needle are further ensured.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of low-wound integral type marrow puncture needle.
Background technology
Bone marrow puncture is the routine diagnosis technology of clinical bone marrow extraction, and marrow puncture needle is medical apparatus and instruments essential in the bone marrow aspiration process.In prior art, while adopting conventional marrow puncture needle bone marrow extraction, need first with entry needle, at point of puncture, carry out anesthetic puncture, and then the bone marrow extraction that punctures at same position with marrow puncture needle, anesthetic puncture and get marrow puncture and separately carry out, because there is little deviation usually in the needle angle of getting marrow puncture and anesthetic puncture, so need to carry out the anesthesia of periosteum multiple spot while anaesthetizing, puncture time is more, has increased patient's misery.
The utility model content
In view of this, the purpose of this utility model is to provide a kind of low-wound integral type marrow puncture needle, can complete anesthesia and get two operations of marrow by one-time puncture, and do not need the anesthesia of periosteum multiple spot, the tissue injury that avoids repeated localised puncture to cause and bleeding risk, at utmost reduce the misery that the patient punctures.
This utility model low-wound integral type marrow puncture needle, comprise needle guard and be through the nook closing member in needle guard, and described nook closing member middle part is provided with injection canal, and the tail end of described nook closing member is connected with syringe.
Further, described needle guard is fixedly connected with handle outward.
Further, described handle is triangle.
The beneficial effects of the utility model:
1, this utility model low-wound integral type marrow puncture needle, it by arranging injection canal on nook closing member, and nook closing member is connected with syringe, can anesthetics be expelled to site of puncture by syringe like this in puncture, site of puncture is consistent with the anesthetics injection site, the anesthetics injection accurately, do not need to carry out the anesthesia of periosteum multiple spot, after being punctured to bone marrow, take out syringe and nook closing member, the syringe of bone marrow extraction is inserted in needle guard and can be extracted bone marrow out, anaesthetize and get marrow and only need one-time puncture, tissue injury and the bleeding risk of effectively avoiding repeated localised puncture to cause, at utmost alleviate the misery of patient's puncture.
2, this utility model low-wound integral type marrow puncture needle, owing to being provided with injection canal on nook closing member, make it possess the function of marrow puncture needle and anesthetics entry needle simultaneously, from structure, the diameter of low-wound integral type marrow puncture needle needle guard site of puncture does not have to increase because of the variation of nook closing member structure, has further guaranteed the advantage of this Novel marrow puncture needle low-wound.
The accompanying drawing explanation
The overall structure schematic diagram that Fig. 1 is this low-wound integral type marrow puncture needle;
Fig. 2 is the nook closing member structural representation.
The specific embodiment
Below in conjunction with drawings and Examples, this utility model is further described.
As shown in the figure, the present embodiment low-wound integral type marrow puncture needle comprises needle guard 1 and is through the nook closing member 2 in needle guard 1 that described nook closing member 2 middle parts are provided with injection canal 3, and the tail end of described nook closing member 2 is connected with syringe 4.
While getting bone marrow, nook closing member 2 is inserted in needle guard 1, and syringe 4 is connected to the tail end of nook closing member 2, nook closing member 2 can strengthen the rigidity of needle guard 1 needle tip, avoids bending in piercing process.In piercing process, by syringe 4, anesthetics is expelled to site of puncture along injection canal 3, site of puncture is consistent with the anesthetics injection site, and accurately, piercing process does not need the anesthesia of periosteum multiple spot in the anesthetics injection; After being punctured to bone marrow, take out syringe 4 and nook closing member 2, the syringe of bone marrow extraction is inserted in needle guard 1 and can be extracted bone marrow out, anaesthetize and get marrow and only need one-time puncture, tissue injury and the bleeding risk of effectively avoiding repeated localised puncture to cause, obviously alleviate patient's misery that punctures.And the diameter of this marrow puncture needle needle guard site of puncture does not have to increase because of the variation of nook closing member structure, has further guaranteed the advantage of this Novel marrow puncture needle low-wound.
As the improvement to this enforcement, described needle guard 1 is outer is fixedly connected with handle 5, holds handle 5 in piercing process and can better control puncture needle, guarantees that puncture completes smoothly.
As the improvement to this enforcement, described handle 5 is triangle, and it can be easily by finger grips, easy to use.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment, this utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not breaking away from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
