Abstract
The utility model discloses a puncturing guide and local anesthetizing needle head. The puncturing guide and local anesthetizing needle head is used for probing the position of blood vessel or serosa during puncturing blood vessel or serosa for locally anesthetizing, and then the needle head and a guide mark are remained to guide the direction of the punching needle. The puncturing guide and local anesthetizing needle head comprises four parts, namely, the needle head, a needle head base, a connecting handle and the guide mark; the needle head is a hollow metal needle of which the remote section is provided with a beveled tip end and the near end is provided with the needle head base; a syringe port communicated with an inner chamber of the needle head and matched with an universal syringe nipple is arranged at the near end of the base; a concave groove rotatably connected a rotating ring of the rotating handle is formed in the middle part of the base; the middle part of the connecting handle is arc-shaped, and the arc shape is sunken for containing the outside diameter of the puncturing needle; the other end of the connecting handle is connected with the guide mark; scales are printed on the guide mark. According to the puncturing guide and local anesthetizing needle head, the guide mark is arranged on the needle head base through the connecting handle, and thereby, the direction of a large-diameter punching needle can be effectively guided, and as a result, the success rate of puncturing blood vessel or serosa can be raised.
Description
Technical field
This utility model belongs to medical device technical field, while being specifically related to a kind of blood vessel or serous cavity puncture, on syringe needle pedestal, configures guide mark in order to instruct the puncture guiding local anaesthesia syringe needle of puncture needle direction by connection handle.
Background technology
While carrying out blood vessel or serous cavity puncture, preferably under instructing, ultrasonic image punctures, to improve puncture success rate, and reduce the generation of complication, but, because ultrasonic device is comparatively expensive, fail to spread to bed other, in case of emergency need in addition to carry out arterypuncture, deep vein puncture, paracentesis pericardii, when thoracentesis or abdominal paracentesis, may have little time to wait for the arrival of ultrasonic device, must in the short time, complete puncture trying one's best, now puncture procedure needs to rely on patient's experience more, may need repeatedly to attempt detecting target for some patient, and regular puncture needle diameter is all thicker, repeatedly attempt increasing wearing contiguous important organ by mistake, local hematoma, arteriovenous fistula, the risk of hemopneumothorax etc.Before puncture, routine need to be carried out near subcutaneous local anesthesia point of puncture, the fine needle that uses local anaesthesia syringe is under negative pressure when the capable local anesthesia of inserting needle, often can penetrate target, now can record the angle of local anaesthesia syringe, when formally puncturing, thick diameter puncture needle to be used rely on the angle of memory to puncture, but simple rely on memory, without quantizating index with without the existence of specific markers, still there is certain blindness in puncture; When the fine needle of local anaesthesia syringe enters target in addition, also can retain syringe needle, then carry out thick diameter puncture needle according to the angle of indwelling needle and formally puncture, because indwelling needle major part enters subcutaneously, outer body is shorter, and guidance quality is not strong.If therefore can use the fine needle of local anaesthesia syringe to detect after target, can either indwelling needle, guiding labelling can be set again on syringe needle, for instructing the puncture direction of thick diameter puncture needle, the success rate that just can improve blood vessel or serous cavity puncture, reduces the generation of puncture related complication.
Utility model content
In order to overcome above-mentioned the deficiencies in the prior art, this utility model provides puncture guiding local anaesthesia syringe needle.
The technical scheme that this utility model adopts is: puncture guiding local anaesthesia syringe needle, comprise syringe needle, syringe needle pedestal, connection handle and guide mark, it is characterized in that: proximal needle is syringe needle pedestal, pedestal middle part forms groove, realize and being rotationally connected with the swivel becket of connection handle, connection handle middle part is curved, and the connection handle other end connects guide mark.
Described syringe needle is hollow metal pin, and section far away is beveled tip, and near-end is syringe needle pedestal.
Described syringe needle pedestal near-end has syringe interface to communicate with syringe needle inner chamber, and syringe interface and universal syringe nipple match, and syringe needle pedestal middle part forms groove, realizes and being rotationally connected with the swivel becket of connection handle.
Described connection handle one end is swivel becket, realizes and being rotationally connected with syringe needle pedestal central slot, and connection handle middle part is curved, and arc-shaped recess is used for holding puncture needle external diameter, and the connection handle other end connects guide mark.
On described guide mark, be printed on scale, guide mark is made up of inelastic light material.
Compared with prior art, the beneficial effects of the utility model are: 1. this utility model is both as local anesthesia set syringe needle, again as puncture gate apparatus, in blood vessel or serous cavity puncture local anesthesia, on syringe needle pedestal, configure guide mark by connection handle, instruct the angle of thick diameter puncture needle, improved the accuracy of puncture; 2. the guide mark configuring by connection handle on syringe needle pedestal and injector syringe outer rim are agreed with well, the inserting needle custom while not affecting local anesthesia; 3. the direct indwelling in target position detecting in local anesthesia process with the syringe needle of guide mark as a token of, does not need to increase extra puncture; 4. connection handle middle part is curved, and arc-shaped recess is used for holding puncture needle external diameter, does not hinder the puncture path of thick diameter puncture needle; 5. on guide mark, be printed on scale, can in the time of puncture, estimate the depth of needle of thick diameter puncture needle; 6. guide mark is made up of inelastic light material, the agravic interference of guide mark while removing injector syringe, non-angular error.
