Abstract
The utility model discloses a pneumothorax puncture needle, which comprises a needle body with an inner cavity. A handle is installed at the back of the needle body; a connecting head is arranged at the back end of the needle body; a needle section located on the needle body is an external thread section and arranged in front of the handle, a positioning cap and a stopping nut are sequentially screwed on the external thread from front to back; the front end of the needle body is in the shape of an arch. The utility model has the advantages that when the pneumothorax puncture needle is punctured into the thoracic cavity, the needle insertion depth can not only be controlled by the positioning cap, but also be adjusted according to different patients and different puncture positions of a patient, so that the puncturing accuracy is ensured, and the pain of a patient is relieved; the front end of the needle body is in the shape of an arch, so that the intercostal blood vessels, nerves, and lung tissues can be prevented from being injured.
Description
Technical field
This utility model belongs to technical field of medical instruments, specifically is a kind of thoracentesis needle.
Background technology
Thoracentesis needle commonly used is that a usefulness rustless steel is made long and thick needle body, the needle body inner hollow, and the one end is provided with needle point, and the other end is provided with the interface that is connected with syringe or negative pressure extractor.During use, point of puncture to the patient carries out local anesthesia earlier, needle point with needle body vertically thrusts in patient's the thoracic cavity again, connect syringe or negative pressure extractor through interface then, intrathoracic gas or liquid are aspirated, and its shortcoming is, the one, and the depth of needle of needle body is wayward, be difficult for fixing when thrusting the back puncture, cause more misery to the patient; The 2nd, the needle body front end is more sharp-pointed, damages patient's intercostal blood vessel, nerve and lung tissue easily.
The utility model content
The technical problems to be solved in the utility model provides a kind of thoracentesis needle that can guarantee the needle body depth of needle.
For solving the problems of the technologies described above, the thoracentesis needle that is provided, comprise the needle body that has inner chamber, the rear portion of needle body is equipped with handle, the rear end of needle body has union joint, its construction features is: being positioned at handle pin section before on the needle body is external thread section, is bolted with limited cap and retaining nut successively on the external thread section after going to.
The front end bending of needle body is curved.
After adopting said structure, being positioned at handle pin section before on the needle body is external thread section, after going to, be bolted with limited cap and retaining nut successively on the needle body, when this thoracentesis needle is pierced into the thoracic cavity, limited cap can be controlled depth of needle, can guarantee puncture accuracy according to different patients and patient's different site of puncture regulation and control depth of needle, reduce patient's misery.The front end bending of needle body is curved, can avoid damaging patient's intercostal blood vessel, nerve and lung tissue.
Description of drawings
The utility model is further introduced below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 is needle body, and 2 is handle, and 3 is limited cap, withdrawing nut till 4, and 5 is union joint.
The specific embodiment
Thoracentesis needle as shown in Figure 1, comprise needle body 1, needle body 1 inner hollow is a sap cavity, the front end bending of needle body 1 is curved, the rear portion of needle body 1 is fixed with handle 2, the rear end of needle body 1 is connected with the union joint 5 that can link to each other with syringe or negative pressure extractor, the middle part pin section that is positioned at handle 2 needle body 1 before is an external thread section, after going to, be bolted with limited cap 3 and retaining nut 4 successively on the external thread section, during use, adjust limited cap 3 to suitable position, turn that retaining nut 4 and limited cap 3 are opposing lives, can prevent that limited cap 3 from moving up and down.
