Along with hydrothorax and pneumothorax are common diseases clinically, very extensive for the use of the thoracentesis needle of two class disease surgeries.Except blood, the pneumothorax due to thoracic trauma, after thoracotomy outside hydrothorax, in recent years, because lung cancer morbidity rate and phthisical sickness rate increase year by year, patients with pleural due to cancerous hydrothorax patient and tuberculosis is increased in a large number, this two classes patient often needs repeated multiple times thoracentesis, and making thus increases greatly to the demand of thoracentesis needle clinically.
The puncture multiplex hydrothorax that extracts in chamber is chemically examined, drain hydrothorax, pneumatosis, hematocele etc., traditional thoracentesis needle is comprised of the piercing needle of metal and the rubber tube that is placed on its rear end, after puncture, puncture needle is difficult for fixing, can not drainage from indwelling, before puncture, must first with blood vessel clamp, close rubber tube, after puncturing successfully, connecting injection needle aspirates again, exhaust also will repeatedly press from both sides after an injection needle and close rubber tube and again aspirate, complex operation, easily cause hemothorax, pneumothorax, the complication such as thoracic cavity infection, because traditional thoracentesis needle is difficult for fixing indwelling the on thoracic wall, thereby can not carry out hydrothorax, pneumatosis, the constant drainage of hematocele.
Utility model content
The purpose of this utility model is to provide a kind of thoracic cannula type puncture needle, and after puncture, puncture casing is easily fixing, simple to operate, improves operation efficiency, alleviates patient's misery, and security performance is good.
This utility model provides a kind of thoracic cannula type puncture needle, comprises, and puncture casing and puncture needle, puncture casing rear end is provided with the first body block body; Puncture needle is provided with the second block body and puncture hands handle; Puncture casing is sheathed on puncture needle, and the second block body on puncture needle matches with the first block body on puncture casing, and puncture casing can be fixed on puncture needle, operation during the convenient operation of puncture handle.
In some embodiments, more comprise drainage tube and the first connecting portion, drainage tube connects puncture casing through the first body block body, the first connecting portion connects drainage tube, the first connecting portion is connected with drainage bag or drainage bottle, and by the first connecting portion, by the hydrops in torso model, pneumatosis is discharged in body, by drainage tube, hydrops, the pneumatosis of discharging in body are collected in drainage bag or drainage bottle again to convenient chemical examination and processing.
In some embodiments, the length of puncture casing is 15-30cm, internal diameter is 5-7mm, the length of puncture needle is greater than the length of puncture casing, and the diameter of puncture needle is less than the internal diameter of puncture casing, and the diameter of drainage tube is less than the internal diameter of puncture casing, facilitate puncture casing can be set on puncture needle, facilitate drainage tube to be conveniently set on puncture casing, puncture needle front end is most advanced and sophisticated, during convenient operation, puncture needle is passed to thoracic cavity.
In some embodiments, the first connecting portion two ends are taper, drainage tube is provided with at least two openings, drainage tube is provided with at least one through hole, the first connecting portion two ends are taper, contribute to be connected with drainage tube, drainage tube is provided with opening and through hole, makes can not block drainage tube because of impurity when discharging hydrops.

Fig. 2 is thoracic cannula type puncture needle, drainage tube, the first connecting portion structural representation of a kind of embodiment of this utility model.
Fig. 3 is that the thoracic cannula type puncture needle of a kind of novel embodiment of this practicality is implemented schematic diagram.
The specific embodiment
Below in conjunction with drawings and the specific embodiments the present invention is described in further detail explanation.
This utility model relates to a kind of thoracic cannula type puncture needle 2, as depicted in figs. 1 and 2, comprises, and puncture casing 1 and puncture needle 2, puncture casing one end is provided with the first body block body 11; Puncture needle 2 is provided with the second block body 21 and puncture handle 22, convenient operation, and puncture casing 1 is sheathed on puncture needle 2 and coordinates and form an assembly away from described puncture handle one end, puncture casing 1 and puncture needle 2 are metal material, convenient through thoracic cavity, simple in structure, easy to operate.
The first connecting portion 4 is plastic tube, cost is low, implements simply, and drainage tube 3 connects puncture casing 1 through the first body block body 11, facilitate drainage tube 3 to be fixed on puncture casing 1, the first connecting portion 4 connects drainage tube 3, coordinates and forms an assembly, and the first connecting portion 4 is connected with drainage bag or drainage bottle, by the first connecting portion 4 by the hydrops in torso model, pneumatosis is discharged in body, then by drainage tube 3, hydrops, the pneumatosis of discharging in body is collected in drainage bag or drainage bottle, convenient chemical examination and processing.
Drainage tube 3 is two, while preventing from performing the operation, drainage tube 3 stops up, damages, and the drainage tube 3 that need to more renew, a drainage tube 3 needs of performing an operation, another root drainage tube 3 is as standby, and another root drainage tube 3 can also be as object of reference, and doctor is when penetrating in patient body by drainage tube 3, understand the length having penetrated, avoid long because of penetrating, drainage tube 3 is touched tissue of patient and is damaged tissue of patient, thereby reduces the misery of patient's operation.
The length of puncture casing 1 is 15-30cm, internal diameter is 5-7mm, the length of trocar sheath and internal diameter are for torso model thickness and drainage tube 3 internal diameter designs, make it be used in thoracentesis operation needs, the length of puncture casing 1 is applicable to thoracic cavity foremost while being 15cm, the length of puncture casing 1 is to be applicable to thoracic cavity least significant end at 30 o'clock, the length of puncture needle 2 is greater than the length of puncture casing 1, the diameter of puncture needle 2 is less than the internal diameter of puncture casing 1, the diameter of drainage tube 3 is less than the internal diameter of puncture casing 1, facilitate puncture casing 1 can be set on puncture needle 2, facilitate drainage tube 3 to be conveniently set on puncture casing 1, puncture needle 2 front ends are most advanced and sophisticated, improve puncture efficiency, reduce the operating time, during convenient operation, puncture needle 2 is passed to breast chamber, in operation because puncture casing internal diameter is little, wound to patient is just very little, drainage tube 3 and opening part are in conjunction with tight, need not carry out operation stitching again to opening.
The first connecting portion 4 two ends are taper, it is more convenient when the design of taper makes to connect drainage tube 3, can not delay because wearing drainage tube 3 operating time, raise the efficiency, reduce the operating time, drainage tube 3 sidewalls are provided with at least two breach 31, and drainage tube 3 is provided with at least one through hole 32, make can not block drainage tube 3 because of impurity when discharging hydrops.
