Description
Technical Field
The utility model relates to the field of medical equipment, in particular to a cannula puncture needle.
Background
The diagnosis and treatment of a plurality of diseases need to puncture patients, and the puncture depth of a common puncture needle cannot be usually mastered due to the experience of an operator during puncture, so that the patient is injured; when the puncture needle is withdrawn, the needle tip and the guide wire block the puncture needle and cannot be extracted, and secondary damage is caused to a patient.
Disclosure of Invention
Aiming at the defects of the prior art, the utility model provides a cannula puncture needle. The utility model discloses a through addding the trocar, make the utility model discloses a clear puncture success that the sleeve pipe pjncture needle can be accurate can take out the sleeve pipe needle point smoothly when withdrawing the pjncture needle can not block the seal wire.
The technical scheme of the utility model is that: the utility model provides a trocar puncture needle, includes pjncture needle joint, pjncture needle tubing and trocar, and pjncture needle tubing connects at pjncture needle joint, its characterized in that: the whole suit of trocar is on pjncture needle tubing, and the trocar includes bushing head, sleeve pipe steel cap and sleeve pipe body, and bushing head front side fixed mounting sleeve pipe steel cap, sleeve pipe steel cap connect the sleeve pipe body, sets up the aperture on the sleeve pipe body, and sleeve pipe body length is 1mm to 2mm shorter than pjncture needle tubing, and sleeve pipe body internal diameter is 0.2mm to 1mm bigger than pjncture needle tubing external diameter.
A trocar puncture needle according to the above, characterized in that: the sleeve joint is made of PP materials.
A trocar puncture needle according to the above, characterized in that: the sleeve pipe body is made of PE or PC materials.
A trocar puncture needle according to the above, characterized in that: the sleeve pipe body is provided with 3 small holes.
A trocar puncture needle according to the above, characterized in that: the length of the puncture needle tube ranges from 30mm to 100mm, and the diameter ranges from 0.5mm to 2 mm.
The utility model has the advantages that: firstly, increased the trocar on the basis of original pjncture needle, can not block when taking out the pjncture needle, reduce repeated puncture, raise the efficiency, reduce the cost. Secondly, simple structure, the device is few, and the connection is reliable between the device, can not appear the phenomenon of part that drops. Thirdly, the position of the sleeve pipe body can be determined very conveniently by an operator, and whether the puncture is successful or not is judged.

Description of reference numerals: a puncture needle connector 1; a puncture needle tube 2; a casing joint 3; a sleeve steel cap 4; a sleeve tube body 5.
Detailed Description
The technical solution of the present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1 to 6, the trocar puncture needle of the present invention includes a puncture needle connector 1, a puncture needle tube 2 and a trocar, and the trocar includes a cannula connector 3, a cannula steel cap 4 and a cannula tube body 5. The puncture needle tube 2 is connected with the puncture needle joint 1, and the trocar is integrally sleeved on the puncture needle tube 2.
The utility model discloses a 3 front side fixed mounting sleeve pipe steel caps 4 of casing joint, 4 connecting sleeve pipe body 5 of sleeve pipe steel cap. The utility model discloses in, bushing body 3 is the PP material, and bushing body 5 is PE or PC material. The PP material does not react when meeting acid-base organic solvents. PE does not react in acid-base organic solvent, is easy to weld, and has toughness, good tensile property and low water absorption. The PC material has good impact strength, stability, glossiness, bacteria inhibition and good pollution resistance. The utility model discloses a set up the aperture on the sleeve pipe body 5, be 3 apertures as shown in figure 6. The utility model discloses a sleeve pipe steel cap 4 is connected, and sleeve pipe steel cap 4 can ensure that casing joint 3 and sleeve pipe body 5 connect the fastening, avoids in the operation process, and spare part falls, simultaneously, whether the aperture through sleeve pipe body 5 has the blood backward flow to confirm or confirm according to actual conditions, and whether operating personnel can be very convenient confirm sleeve pipe body 5's position, judge whether the puncture is successful.
The length range of the puncture needle tube 2 of the utility model is 30mm to 100mm, and the diameter range is 0.5mm to 2 mm. When the puncture needle tube is matched, the length of the sleeve tube body 5 is 1mm to 2mm shorter than that of the puncture needle tube 2, and the inner diameter of the sleeve tube body 5 is 0.2mm to 1mm larger than the outer diameter of the puncture needle tube 2.
The casing puncture needle of the utility model is similar to an injection needle in appearance, and can be used for the drainage of puncture cannulas of biliary tract, kidney, bladder, etc., and the arteriovenous alternation therapy, the radiography examination, etc. When in use, the puncture is carried out through the trocar puncture needle, the puncture needle joint 1 and the puncture needle tube 2 are drawn out after the puncture is successful, and the trocar is left in the body and is used for the intervention of surgical instruments.
Claims (5)
