Abstract
The utility model relates to a medical device, in particular to a thoracic puncture needle for taking a medium from a human body and infusing medicinal liquid into the human body. The thoracic puncture needle is provided with a needle body, the front end of the needle body is provided with an arc-shaped needle point, and the rear part of the needle body is provided with an operating handle. The thoracic puncture needle is characterized by arranging a length measuring scale is arranged on the needle body, the rear end of the needle body is provided with an syringe needle connecting seat, a sliding sleeve is arranged on the needle body, a positioning screw is arranged on the sliding sleeve, and the sliding sleeve is connected with a sucking disc through a connecting rod. The use of the thoracic puncture needle comprises the following steps of: firstly, selecting a puncture point and performing local anesthesia; then, vertically puncturing the needle point of the needle body into the thoracic cavity of a patient, and determining the puncture depth according to the length measuring scale on the puncture needle; and finally, connecting a syringe interface with the needle connecting seat on the puncture needle to suck a gas or a liquid in the thoracic cavity to complete puncture. If the puncture needle needs to be retained, the sliding sleeve is connected with the needle body through the positioning screw, and then the sucking disc is sucked with the human body of the patient. The thoracic puncture needle has the advantages of convenience for use, simplicity of operation, small patient wound, accurate puncture, retainability and the like, and intercostal blood vessels, nerves and lung tissue of the patient can not be damaged.
Description
Technical field
This utility model relates to a kind of medical apparatus, and particularly a kind of medium that takes out in the human body is imported the intravital thoracentesis needle of people with medicinal liquid simultaneously.
Background technology
As everyone knows, the purpose of thoracentesis operation is the main force that diagnoses and alleviate internal organs, and thoracentesis needle commonly used is that a usefulness rustless steel is processed long, thicker needle body, and needle body is a hollow; The one of which end is provided with needle point, and the other end is provided with the interface that is connected with syringe or negtive-pressure implement, and during use, earlier selected point of puncture also carries out local anesthesia; Needle point with needle body vertically thrusts in patient's the thoracic cavity again, and the pumpback of trying is then extracted out like no gas or liquid, continues suitable inserting needle to overflowing of gas or liquid arranged; Connect syringe or negtive-pressure implement through interface then, intrathoracic gas or liquid are aspirated, to accomplish puncture; When needs during to thoracic cavity wind injection, then need extract puncture needle, inject with syringe; Its weak point is: 1, not easy to operate, depth of needle is wayward, thrusts assorted difficult the fixing of back puncture; Cause more misery to the patient, 3, this puncture needle can not carry out catheter drainage, must repeated localised puncture aspirate intravital gas of patient or liquid; Be prone to cause the pachynsis pleurae adhesion, need during injection to puncture with syringe separately, increased patient's pain.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes prior art, provide a kind of simple to operate, patient's wound is little, the thoracentesis needle that can keep somewhere.
This utility model can reach through following measure:
A kind of thoracentesis needle is provided with needle body, and the needle body front end is provided with arcual needle point; The rear portion of needle body is provided with ribbon gymnastics and makes handle; It is characterized in that needle body is provided with the length metering scale, needle rear end is provided with the syringe needle Connection Block, and needle body is provided with sliding sleeve; Sliding sleeve is provided with dog screw, and sliding sleeve is connected with sucker through connecting rod.
When this utility model uses; Earlier selected point of puncture also carries out local anesthesia, and the needle point with needle body vertically thrusts in patient's the thoracic cavity again, can be according to the decision of the length metering scale on the puncture needle paracentesis depth during puncture; Then syringe interface is connected with needle holder on the puncture needle intrathoracic gas or liquid are aspirated; To accomplish puncture, puncture needle needs to keep somewhere, and then earlier sliding sleeve is connected with needle body with dog screw; Then sucker is inhaled to connect with patient body mutually and get final product, have advantages such as easy to use, simple to operate, that patient's wound is little, puncture accurately, does not damage blood vessel, nerve and the lung tissue of patient's intercostal and can keep somewhere.
Description of drawings
Fig. 1 is a kind of structural representation of this utility model.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is further described:
As shown in Figure 1, a kind of thoracentesis needle is provided with needle body 1; Needle body 1 front end is provided with arcual needle point, and the rear portion of needle body 1 is provided with ribbon gymnastics and makes handle 2, and is above-mentioned identical with prior art; This does not give unnecessary details, and this utility model is characterised in that needle body 1 is provided with the length metering scale, and needle body 1 rear end is provided with syringe needle Connection Block 3; Needle body 1 is provided with sliding sleeve 4, and sliding sleeve 4 is provided with dog screw 5, and sliding sleeve 4 is connected with sucker 7 through connecting rod 6; When this utility model used, earlier selected point of puncture also carried out local anesthesia, and the needle point with needle body vertically thrusts in patient's the thoracic cavity again; Can be during puncture according to the length metering scale on puncture needle decision paracentesis depth, then syringe interface is connected with needle holder on the puncture needle intrathoracic gas or liquid are aspirated, puncture to accomplish; Puncture needle needs to keep somewhere; Then elder generation is connected with dog screw sliding sleeve with needle body, then sucker is inhaled to connect with patient body mutually to get final product, and has advantages such as easy to use, simple to operate, that patient's wound is little, puncture accurately, does not damage blood vessel, nerve and the lung tissue of patient's intercostal and can keep somewhere.
