Abstract
The utility model discloses a penetrative positioning pleural casing puncture needle, which relates to a medical apparatus, belongs to the technical field of medical apparatuses and is used for overcoming the defects of complex operation, easiness in causing chest cavity infection, difficulty in retaining and fixing the puncture needle for performing continous drainage of pleural effusion and pneumatosis, in capability of accurately positioning after penetration, easiness in causing hemothorax and pneumothorax complicating diseases and the like existing in the conventional puncture needle. The penetrative positioning pleural casing puncture needle by consisting of a penetrative casing needle (2) and a metal puncture needle (1) arranged in the penetrative casing needle (1), wherein a needle base interface (6) at the back end of the metal puncture needle (1) is provided with a push-pull saccule (7); the front part of a puncture handle of the puncture casing needle (2) is provided with a side-through drain pipe (11); and a rubber plug (13) of which a middle pipeline can be closed automatically is embedded into the middle part of the puncture handle. The penetrative positioning pleural casing puncture needle has the advantages that: (1) a puncture needle special for air suction, liquid suction and drainage for pleural puncture is provided, operation steps are simple, and the chest infection probability is lowered; (2) a penetrator is positioned timely, can be fixed on a chest wall and can be retained in a chest cavity, so that the complicating diseases such as hemothorax, pneumohemothorax and the like are effectively avoided; and (3) the puncture needle has a simple structure and low manufacturing cost, and is convenient to produce and assemble.
Description
Technical field
This utility model relates to a kind of thoracic drainage and thoracentesis and uses the sleeve pipe puncture needle, belongs to technical field of medical instruments.
Background technology
Thoracentesis is used for extracting hydrothorax chemical examination, drain hydrothorax, pneumatosis, hematocele etc. more, uses commonplace, traditional thoracentesis needle clinically and is made up of the piercing needle of metal and the rubber tube that is placed in its rear end; Be difficult for grasping paracentesis depth during puncture; Puncture back puncture needle is difficult for fixing, can not drainage from indwelling, must elder generation close rubber tube before the puncture with the blood vessel clamp; Connecting injection needle after puncturing successfully again aspirates; Exhaust also will press from both sides repeatedly behind the injection needle and close rubber tube and aspirate once more, complex operation causes complication such as hemothorax, pneumothorax, thoracic cavity infection easily; Because traditional thoracentesis needle is difficult for fixing indwelling the on thoracic wall, thereby can not carry out the CD of hydrothorax, pneumatosis, hematocele.
Summary of the invention
The purpose of design of this utility model is the specialized barrel puncture needle that a kind of thoracic drainage and thoracentesis is provided for the clinicist; Overcome traditional puncture needle complex operation; Be prone to cause thoracic cavity infection; Puncture needle is difficult for keeping somewhere the CD that fixedly carries out hydrothorax, pneumatosis, hematocele, can not promptly and accurately locate after penetrating, and is prone to cause defectives such as hemothorax, pneumothorax complication.
Penetrate location thoracic cavity sleeve pipe puncture needle by paracentesis trocar (2) be loaded on its interior metal puncture pin (1) and form; The hub interface (6) of metal puncture pin (1) rear end is provided with the sacculus (7) that can plug; The puncture handle front portion of paracentesis trocar (2) is provided with the logical drainage tube (11) of side, but the middle part is embedded with the rubber stopper (13) of intermediate conduit auto-closing.
[0005]This utility model possesses following advantage: (1) is that thoracentesis is bled, the special-purpose puncture needle of drawing liquid and drain, and operating procedure is simple, reduces the thoracic cavity infection chance.(2) penetrate timely location, can be fixed on the thoracic wall, can in the thoracic cavity, keep somewhere, can avoid the generation of complication such as hemopneumothorax effectively.(3) this puncture needle is simple in structure, and production and assembly are convenient, and cost is low.

The specific embodiment
This utility model comprises metal puncture pin 1 and paracentesis trocar 2; Metal puncture pin 1 is made up of piercing needle 3 and the needle stand 4 that is connected in its rear portion; Both communicate by tube chamber, and the front portion of needle stand 4 is a needle stand handle 5, and the rear end is a hub interface 6; Sacculus 7 is connected in the tube chamber of hub interface 6 through the adapter 8 that connects on it, can it be plugged.The drain sleeve pipe 9 of paracentesis trocar 2 front ends is connected with the puncture handle 10 of rear end, and tube chamber communicates, and the front portion of puncture handle 10 is provided with the logical drainage tube 11 of side; The end of the logical drainage tube 11 of side is the joint 12 of band single-way switch; Its tube chamber communicates with the tube chamber of puncture handle 10, but the middle part of puncture handle 10 is embedded with the rubber stopper 13 of intermediate conduit auto-closing, and the rear portion of puncture handle 10 is a handle set 14; Piercing needle 3 can insert in the drain sleeve pipe 9 through the intermediate conduit of rubber stopper 13; Piercing needle 3 is pulled out the intermediate conduit auto-closing of back rubber stopper 13, and the tip of piercing needle 3 slightly grows the front end of drain sleeve pipe 9, and needle stand handle 5 just is embedded in the tube chamber of handle set 14.During thoracentesis; Earlier metal puncture pin 1 is loaded in the paracentesis trocar 2, when paracentesis trocar has just punctured after subcutaneous, pulls up sacculus 7 and it is pinched and be embedded in again in the hub interface 6 after flat; Slow inserting needle; When sacculus 7 began to fill appearance, the prompting piercing needle just penetrated thoracic wall, can metal puncture pin 1 be pulled out in paracentesis trocar 2; Drain sleeve pipe 9 advanced a little be fixed on the thoracic wall, the joint 12 that can pass through the logical drainage tube 11 terminal band single-way switch of side is bled, drawing liquid and connect drainage bag or drainage bottle carries out drain.
Know that by Fig. 2 piercing needle on the metal puncture pin 13 is processed by stainless steel material, piercing needle 3 length 12cm, No. 9 puncture needle is thick; Needle stand 4 is processed length 2cm, needle stand handle 5 long 6mm, diameter of section 4mm by transparent plastic; Needle stand 4 remainder diameter of sections are gradually thick to terminal 7mm, the tube chamber diameter of section 4mm of hub interface 6, and sacculus 7 big or small 1.5cm * 2cm are processed by rubber; Taking over 8 is transparent plastic material, length 1cm, and diameter of section 4mm just closely embeds in the tube chamber of hub interface 6.
Know that by Fig. 3 paracentesis trocar 2 is processed length 10cm, the length 3cm of puncture handle 10 by plastic material; Shaped somewhat is cone, the lumen diameter 5mm of handle set 14, rubber stopper 13 long 6mm, the middle part that is embedded in handle set 14 that can be firm; Drain sleeve pipe 9 has certain flexibility, and is flexible, and length 7cm slightly is longer than drain sleeve pipe 9 after piercing needle 3 inserts; Rugosity is that piercing needle 3 can just insert, the length 20cm of the logical drainage tube 11 of side, lumen diameter 4mm.
