To achieve the above object, the utility model provides the following technical solutions:
A kind of arthrocentesiS instrument includes mainly paracentesis trocar, injection needle, injection syringe, puncture needle and support Plate.The head end of the paracentesis trocar is equipped with the syringe needle of three prismatic, and offers the liquid inlet/outlet of ellipse, in the tail of paracentesis trocar End is fixed with paracentesis trocar needle stand, through-hole is equipped on the outer wall of paracentesis trocar, and through hole is welded with drawing liquid head, the pumping The end of liquid head is socketed with liquid suction pipe, and the end of the liquid suction pipe is sleeved on the head end of puncture needle;The injection needle is from wearing It pierces trocar needle stand to be inserted into paracentesis trocar, and the tail end of injection needle is fixed with injection needle needle stand, in the outer wall of injection needle needle stand It is equipped with external screw thread, the inner wall of paracentesis trocar needle stand is equipped with corresponding internal thread, therefore paracentesis trocar needle stand and injection needle needle The fixation between paracentesis trocar and injection needle may be implemented in threaded connection between seat;The injection needle needle stand is socketed in injection note The head end of emitter;The puncture needle and injection syringe are adhesive on supporting plate.
Further scheme as the utility model:The liquid suction pipe uses PE hoses, and liquid suction pipe is equipped with pipe clamp.
Further scheme as the utility model:The paracentesis trocar needle stand is fixedly connected in the form of gluing to be worn Pierce trocar.
Further scheme as the utility model:It is printed on graduation mark on the surface of the paracentesis trocar.
Further scheme as the utility model:The injection needle needle stand and paracentesis trocar needle stand are all made of PP materials Matter is made.
The beneficial effects of the utility model:The utility model connects puncture needle and injection syringe by using supporting plate It is connected into integral combined structure, facilitate medical staff while operating puncture needle and injection syringe, in this way in reality Both the position offset between paracentesis trocar and injection needle will not occur during operation, while injection and drawing liquid are connected It is continuous to carry out, reduce the injury to patient.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
In figure:Paracentesis trocar 1;Injection needle 2;Paracentesis trocar needle stand 3;Graduation mark 4;Liquid inlet/outlet 5;Drawing liquid head 6;Injection is noted Emitter 7;Puncture needle 8;Supporting plate 9;External screw thread 10;Liquid suction pipe 11;Pipe clamp 12;Injection needle needle stand 13.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work The every other embodiment obtained, shall fall within the protection scope of the present invention.
