Abstract
The utility model relates to a medical instrument facilitating use of a puncture needle. The puncture needle comprises a needle core, a needle head sleeved on the periphery of the needle core and needle bases respectively arranged at the tail end of the needle core and at the tail end of the needle head. The medical instrument is characterized in that the needle base at the tail end of the needle head is connected with a needle cylinder through a connecting pipe piece so as to facilitate operation of the needle cylinder at any station. The medical instrument can reduce situations of needle point displacement and visceral injuries caused by respiration of a patient and other factors, enhances safety of intervention operation and greatly facilitates operation of medical staff.
Description
Technical field:
This utility model relates to a kind of medical apparatus, particularly a kind of medical apparatus of being convenient to the puncture needle use.
Background technology:
The use of puncture needle at present is general in the extreme, and it is widely used in occasions such as intervertebral disc puncture, arthrocentesiS, the puncture of myalgia point, medicine injection.Puncture needle integral body mainly comprises nook closing member and is enclosed within the syringe needle of nook closing member periphery, and the needle stand that is located at nook closing member, syringe needle tail end respectively, during use, puncture successfully earlier, take out the nook closing member in the syringe needle again, needle stand at the syringe needle tail end connects syringe (as shown in Figure 1), owing to syringe needle, syringe are rigid structure, therefore, in inserting needle tapping process, needle point is difficult for fixing, may cause the pin displacement moving, causes tissue injury in the art, complication such as hemorrhage; In addition, when using syringe to carry out operation such as liquid suction or medicine injection, medical personnel must carry out the adjustment of erect-position and posture according to the different site of puncture of patient, bring huge inconvenience for the use of puncture needle.
Summary of the invention:
The purpose of this utility model is to provide a kind of medical apparatus that puncture needle uses of being convenient to, and this utensil structure is simple, reasonable in design, is conducive to medical personnel and carries out operations such as liquid suction or medicine injection after puncture.
This utility model is convenient to the medical apparatus that puncture needle uses, described puncture needle comprises nook closing member and is enclosed within the syringe needle of nook closing member periphery, and the needle stand that is located at nook closing member, syringe needle tail end respectively, it is characterized in that: connect syringe by the switching pipe fitting on the needle stand of described syringe needle tail end, so that syringe is at any station manipulation.
Above-mentioned switching pipe fitting is plastic flexible pipe, is provided with the flow-stopping clip of controlled controlling flow amount at the end of plastic flexible pipe, is respectively equipped with the joint that docks with needle stand, syringe in the plastic flexible pipe two ends.
Above-mentioned plastic flexible pipe is medical prolongation pipe.
Above-mentioned switching pipe fitting is the universal joint that two ends can be docked with needle stand, syringe.
Above-mentioned syringe needle outer race is provided with needle cannula.
This utility model is convenient to medical apparatus that puncture needle uses in use, take off needle cannula, after puncturing, insert switching pipe fitting (this switching pipe fitting can be universal joint, also says it can is plastic flexible pipe) behind the extraction nook closing member, connect syringe at the switching pipe fitting, open flow-stopping clip, can carry out liquid suction or medicine injection, can close flow-stopping clip when being full of in the syringe when liquid or injectable drug finish, because the use of flow-stopping clip, can prevent that gas from entering in the body by the switching pipe fitting or liquid is counter flows; The switching pipe fitting is soft pipeline and can adjusts direction arbitrarily, has reduced the needle point displacement and the visceral injury that cause because of factors such as patient respiratories, has strengthened the safety of interventional procedure, and has greatly facilitated operation of medical workers.
Description of drawings:
Fig. 1 is the organigram that existing puncture needle uses;
Fig. 2 is the profile construction sketch map of puncture needle;
Fig. 3 is the use organigram of this utility model embodiment.
The specific embodiment:
This utility model is convenient to the medical apparatus that puncture needle uses, described puncture needle includes nook closing member 1 and is enclosed within the syringe needle 2 of nook closing member 1 periphery, and the needle stand 3 that is located at nook closing member, syringe needle tail end respectively, after syringe needle 2 is extracted nook closing member 1 out, connect syringe 5 by switching pipe fitting 4 on the needle stand 3 of syringe needle tail end, so that syringe is at any station manipulation.
This utility model wherein a kind of preferred embodiment is (as shown in Figure 3), above-mentioned switching pipe fitting 4 is plastic flexible pipe, be provided with the flow-stopping clip 8 of controlled controlling flow amount at the end of plastic flexible pipe, be respectively equipped with the joint 6 that docks with needle stand, syringe in the plastic flexible pipe two ends.This plastic flexible pipe can be existing medical prolongation pipe commonly used, uses syringe by connecting prolongation pipe back, makes the position of syringe flexible relatively, and operation is very easy.
The another kind of embodiment of this utility model is that above-mentioned switching pipe fitting is the universal joint that two ends can be docked with needle stand, syringe, uses syringe after connecting universal joint, also allows the operating position of syringe more flexible relatively in the past.
Above-mentioned syringe needle 2 outer race are provided with needle cannula 7.
This utility model is convenient to medical apparatus that puncture needle uses in use, take off needle cannula, after puncturing, insert switching pipe fitting (this switching pipe fitting can be universal joint, also says it can is plastic flexible pipe) behind the extraction nook closing member, connect syringe at the switching pipe fitting, open flow-stopping clip, can carry out liquid suction or medicine injection, can close flow-stopping clip when being full of in the syringe when liquid or injectable drug finish, because the use of flow-stopping clip, can prevent that gas from entering in the body by the switching pipe fitting or liquid is counter flows; The switching pipe fitting is soft pipeline and can adjusts direction arbitrarily, has reduced the needle point displacement and the visceral injury that cause because of factors such as patient respiratories, has strengthened the safety of interventional procedure, and has greatly facilitated operation of medical workers.
The above only is preferred embodiment of the present utility model, and all equalizations of doing according to this utility model claim change and modify, all at covering scope of the present utility model.
