Abstract

The utility model relates to a thoracic cavity fast puncture and drainage casing needle which can simplify thoracentesis and thoracic close drainage operations. A cuspidal puncture needle is sheathed in a truncate drainage needle to combine a casing needle to be used. The utility model accomplishes the operation of puncture and drainage at one time. The utility model and a common syringe are assembled into a working condition, and a point of puncture of a thorax is partially paralysed or not paralysed, thus the utility model is vertically punctured into the thoracic cavity, and then the puncture needle is drawn out after pumpback proves that the utility model is in place. The drainage needle is connected with a drainage tube and is fixed. The overall process of the operation can be completed in 20 seconds.

Description

The quick puncture drainage trocar in thoracic cavity

This utility model relates to a kind of medical apparatus and instruments that is used for thoracic drainage and thoracentesis, can simplify the operation of present thoracentesis and closed drainage of pleural cavity.

Thoracentesis, drain are one of the main observation of aerothorax, hematocele, hydrops and treatment means.The operational approach of present clinical puncture, drain has two kinds: 1, thoracentesis: the normal injection syringe needle connects syringe, in point of puncture syringe needle is thrust the thoracic cavity, bleeds on demand, drawing liquid, and end of operation is extracted syringe needle.2, closed drainage of thoracic cavity operation: need to select surgery location by treatment, local anesthesia, make the about 2CM of intercostal space place's skin incision, passivity is separated the thoracic wall tissue, the rubber drainage tube of clamp one suitable bore inserts the about 2CM in thoracic cavity, fixedly drainage tube is in case deviate from for skin suture, suture, and the drainage tube far-end connects drainage bottle.Treatment is pulled out drainage tube after finishing and is bound up a wound.(please refer to: 1, " huang jiasi surgery ", the 4th edition, Wu Jieping, attack Fa Zu chief editor, the People's Health Publisher.2, " modern breast surgery ", front page, Huang Xiaomai chief editor, People's Medical Officer Press).The main deficiency of above-mentioned Therapeutic Method: 1, the thoracentesis drawing liquid of can only disposablely bleeding, suction finishes and promptly pulls out pin, when gas or liquid appear in thoracic cavity once more, need puncture once more or makes other treatment, is unfavorable for the continuous observation and the treatment of disease.2, the closed drainage of thoracic cavity operation therapeutical effect is thorough, but operation is complicated, time-consuming, damages bigger.Skilled clinician finished closed drainage of thoracic cavity operation about about 2 minutes under an assistant cooperates.Therefore influenced this treatment in clinical extensive use.

The purpose of this utility model provides the quick puncture drainage trocar in a kind of thoracic cavity, it can simplify thoracentesis and closed drainage of pleural cavity operation, and two operations of puncture and drainage in thoracic cavity are once finished, and is of many uses, easy and simple to handle rapid, wound can drop to clinical possible bottom line at present.

The purpose of this utility model is achieved in that puncture needle likeness in form normal injection syringe needle, and needle point is sharp keen inclined-plane, and drainage needle needle body internal diameter slightly is coarser than the external diameter of puncture needle needle body, and its needle point is a tack.The uropore of puncture needle and drainage needle all can connect use with ordinary syringe.When using this trocar,,, become duty with the socket in turn of puncture needle, drainage needle, ordinary syringe by sterile working's principle.The thoracentesis point is done local anesthesia.Sb.'s sickness becomes critical or puncture needle can not anaesthetized when thin yet.This trocar is thrust perpendicular to thoracic wall, touch thoracic wall until baffle plate.The inclined-plane of puncture needle should towards and press close to the next rib upper limb of intercostal space.After the puncture of syringe pumpback proof puts in place, extract puncture needle out, drainage needle connects drainage tube and drainage bottle.So far finished the operation of thoracic drainage and thoracentesis.This trocar is as wearing the lastblock sterile gauze in advance, then can simplify the wrapping process, the puncture needle needle stand is made a labelling, can show the orientation of pinpoint inclined plane, the baffle plate place of drainage needle is the inserting needle limit, can drainage needle properly be fixed in thoracic wall with 2-4 bar adhesive plaster by the drainage needle baffle plate.The drainage needle needle body should be than about the long 2CM of thoracic wall thickness.Thoracic wall thickness can be determined with ultrasonic examination or empirical value.For the people who is suitable for different thoracic wall thickness and various disease uses this trocar, can be made into different length, the series of products of different bores.According to clinical custom, can be made into the serial puncture drainage trocar of the long respectively 40mm of drainage needle, 60mm, 80mm, 100mm, bore 2.0mm, 4.0mm, 6.0mm, 8.0mm, 10.0mm.

Owing to adopt such scheme, can simplify the operation of thoracentesis, drain, to save time, and wound is reduced to clinical possible bottom line at present, this trocar is simple in structure.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the vertical section structural map of the puncture needle of the quick puncture drainage trocar in thoracic cavity.

Fig. 2 is the vertical section structural map of the drainage needle of the quick puncture drainage trocar in thoracic cavity.

Fig. 3 is puncture needle and the drainage needle vertical section structural map when connecting together.

Among the figure 1, puncture needle syringe needle 2, puncture needle needle body 3, puncture needle needle stand head 4, gauge point 5, puncture needle uropore 6, drainage needle syringe needle 7, drainage needle needle body 8, baffle plate 9, drainage needle uropore be in Fig. 1, puncture needle syringe needle (1) is sharp keen inclined-plane, puncture needle needle stand head (3) is taper, puncture needle uropore (5) can connect use with ordinary syringe, the bevel direction of Paracentesis needle holder body mark point (4) indication needle point.

In Fig. 2, drainage needle syringe needle (6) is a tack, the outer rim slyness, and baffle plate (8) limits depth of needle, and drainage needle uropore (9) can connect use with ordinary syringe.

In Fig. 3, puncture needle syringe needle (1) inclined-plane is exposed to outside the drainage needle syringe needle (6) just, puncture needle needle body (2) and drainage needle needle body (7) no-float, tension neither, not obvious again gas leakage, the conical nose of puncture needle needle stand (3) closely is socketed in the uropore (9) of drainage needle, promptly becomes the duty that punctures and draw trocar fast in the thoracic cavity after the uropore of puncture needle (5) the socket ordinary syringe.

When using this trocar to carry out thoracentesis, measure thoracic wall thickness with ultrasonic examination earlier, or rule of thumb estimate thoracic wall thickness, select the quick puncture drainage trocar in thoracic cavity for use, according to the work OFF state that is assembled into shown in Figure 3 than long 2 centimetres of thoracic wall thickness.Point of puncture sterilization, numb broken, this trocar is vertically thrust the thoracic cavity at the place, intercostal space, until baffle plate contact thoracic wall, after the puncture of syringe pumpback proof puts in place, syringe is extracted out together with puncture needle, preprepared drainage tube is connected to the drainage needle uropore, and the drainage tube other end places under the drainage bottle liquid level, with adhesive plaster the drainage needle baffle plate properly is fixed on the thoracic wall.The thoracentesis operation is promptly finished.
