Abstract
The utility model designs an integrated medical bone marrow puncture needle which comprises a puncture needle tube, a puncture needle tube handle, a needle core and a needle core handle, wherein an anesthetic needle tube is arranged in the puncture needle tube, an injection port is arranged on the needle core handle, a connecting tube for connecting the anesthetic needle tube and the injection port is arranged in the puncture needle tube handle, and the tip of an inclined plane of the anesthetic needle tube is arranged outside the puncture needle tube. A sealing plug is arranged at the position of the injection port. A positioning buckle is arranged at the connecting position between the puncture needle tube handle and the needle core handle. Scale lines are arranged at the front end of the puncture needle tube. The outer surface of the puncture needle tube is wrapped by a screw rod. A position limiter and a positioning nut are arranged on the screw rod. The integrated medical bone marrow puncture needle can complete anesthesia and puncture in one step, effectively reduce the operating procedures, and limit puncture injuries at one point, thereby effectively reducing tissue injuries and bleeding risks caused by operation; meanwhile, as a puncture point and an anesthetic point can be combined together, the integrated medical bone marrow puncture needle can obviously ease pains of a patient in the operating process, thereby leading the whole operating process to favorably carry out. Therefore, the integrated medical bone marrow puncture needle is convenient for popularization.
Description
Technical field
This utility model relates to a kind of marrow puncture needle, particularly a kind of integrated medical marrow puncture needle.
Background technology
Medically, bone marrow puncture (bone marrow puncture) is a diagnostic techniques a kind of commonly used of taking bone marrow fluid, and marrow puncture needle is an apparatus essential in the bone marrow aspiration process.Existing bone marrow aspiration technology, generally be to inject the local anaesthetics lignocaine at patient's bone marrow aspiration position with the 5ml syringe earlier, successively carry out local infiltration anesthesia by skin to periosteum, extract the anesthesia syringe then, use marrow puncture needle again instead at the vertical inserting needle in same position, enter medullary cavity and extract bone marrow.The whole operation flow process is more, operating time is long, and after marrow puncture needle advances skin because a little difference of needle angle, skin-tightening degree etc., skin before often might departing from and periosteum anesthesia point, thereby increased tissue injury and risk of bleeding on the one hand, also increased patient's local pain sense on the other hand, made the patient poor the compliance of bone marrow aspiration operation, and directly have influence on the whole operation process and can carry out smoothly, therefore to operator's requirement also than higher.
Summary of the invention
Problems such as the purpose of this utility model provides a kind of integrated medical marrow puncture needle, and it is many to efficiently solve the operating process that exists in the prior art, and the operating time is long, and the operation damage is big, and the patient suffering is many.This utility model designs a kind of integrated medical marrow puncture needle, comprise puncture needle tubing, puncture syringe handle, nook closing member, nook closing member handle, be provided with the anesthesia needle tubing in the described puncture needle tubing, described puncture syringe handle is provided with the injection interface, is provided with the connection tube that connects anesthesia needle tubing and injection interface in the puncture syringe handle.The beveled tip of described anesthesia needle tubing places outside the puncture needle tubing.Described injection seam is provided with sealing-plug.Junction between described puncture syringe handle and the nook closing member handle is provided with the location buckle.Described puncture needle tubing front end is provided with graduation mark.Described puncture needle tube outer surface is surrounded by a screw rod, and described screw rod is provided with stop and setscrew nut.This utility model can make anesthesia and puncture once finish, effectively reduced operating process, can make penetration damage be confined to a point, thereby effectively reduce tissue injury and the hemorrhage risk that causes because of operation, simultaneously because point of puncture and anesthesia point are united two into one, therefore can obviously alleviate the misery in patient's operating process, make that the whole operation process is more smooth carries out, be convenient to penetration and promotion.
Description of drawings
Below in conjunction with accompanying drawing this utility model is elaborated:
Accompanying drawing 1 is embodiment 1 structural representation of the present utility model,
Accompanying drawing 2 is the structural representation after embodiment 1 of the present utility model removes nook closing member and sealing-plug,
Accompanying drawing 3 is embodiment 2 structural representations of the present utility model,
Accompanying drawing 4 is the structural representation after embodiment 2 of the present utility model removes nook closing member and sealing-plug.
The specific embodiment
Embodiment 1
Comprise puncture needle tubing 1, puncture syringe handle 2, nook closing member 3, nook closing member handle 4 among Fig. 1 and Fig. 2, be provided with anesthesia needle tubing 5 in the described puncture needle tubing, described puncture syringe handle is provided with injection interface 6, is provided with the connection tube 7 that connects anesthesia needle tubing and injection interface in the puncture syringe handle.The beveled tip of described anesthesia needle tubing places outside the puncture needle tubing.Described injection seam is provided with sealing-plug 8.
In the bone marrow aspiration process, the operator takes off sealing-plug, the syringe of band local anesthetic is connected with the injection interface, the nook closing member that will puncture installs, to locate the buckle chucking, then this utility model pinpoint inclined plane is thrust point of puncture skin up, Yi Bian Yi Bian slowly push away the vertical inserting needle of medicine until anaesthetizing periosteum.Then take off the syringe of anesthesia usefulness, sealing-plug continues vertical inserting needle to medullary cavity beyond the Great Wall, extracts nook closing member, extracts the bone marrow fluid censorship.
