Abstract
The utility model discloses a dual needle for section and sampling check, belonging to a surgical instrument for lungs used in the needle biopsy. A needle core is formed by a hollow body, a hollow hook-shaped cutter is arranged on the front end of the hollow body. A needle tube is a 45 DEG-shaped single sharp tine, and positioning sleeve of the depth of needle insertion which is controlled by a rotary knob is matched with the needle tube. The dual needle for section and sampling check has high accuracy of taking out the pathological changes tissue, can avoid the complication of the needle biopsy, and can treat the pathological changes by injecting the medication.
Description
This utility model belongs to a kind of aspiration biopsy pin of pneumochirurgia apparatus.
According to retrieval relevant technologies data, the lung puncture biopsy of adopting at present both at home and abroad attracts pin, cutting needle or trepan pin all to have different separately pluses and minuses: attract that pin is elongated, bore is little, tissue injury and hemorrhage chance be few, the complication of no aspiration biopsy (pneumothorax, bloody sputum, hemothorax, thoracic cavity infection, subcutaneous emphysema etc.) takes place, but the chance that obtains pathological tissues is few, and the hard toughness pathological tissues is difficult for thrusting; The bore of cutting needle is thick, and the pathological tissues of obtaining is many, be easy to make pathological diagnosis, but tissue injury is heavier, and the complication of aspiration biopsy is easy to take place; The trepan pin can be obtained the cylindric rectangular pathological tissues piece of 1.5～2cm, is easy to pathologic finding, but the concurrent pneumothorax of injured tissues, symptom such as hemorrhage.A kind of formation of China patent CN852037-22V bulletin by needle tubing and nook closing member, its needle tubing front end stria has the slot type puncture needle of cutting edge, promptly is trepan pin type, and this slot type puncture needle is difficult for cutting to the hard toughness pathological tissues.
The purpose of this utility model provides a kind of modified model that attracts and cut two class pin type structural advantages of taking into account and cuts the suction two purpose meedle.Its solution is: needle tubing and nook closing member still adopt medical stainless hollow steel pipe material, nook closing member is made the hollow body that front end has solid hook-shaped parting tool, needle tubing is made the single sharpened end that head is 45 shapes, and adorn one at the circumferential surface of needle tubing and can make straight skidding and regulate, and by the depth of needle positioning sleeve of annular knurl screw knob stop.
Like this, in the lung puncture biopsy, can pass through the definite location dimension of irradiation, photo and perspective and, take out pathological tissues exactly by the determined location dimension of television screen, easy to operate and safe; When inserting needle was cut the suction pathological tissues, injectable drug reduced hemorrhage and avoids the complication of aspiration biopsy to take place simultaneously; Also can in an inserting needle, cut and the more pathological tissues of suction different parts in addition, so be easy to carry out cytology, histology, bacteriological inspection and diagnosis.
Accompanying drawing 1 has been described an embodiment of the present utility model.
As shown in the figure, cut and inhale two purpose meedle a needle tubing (2) and a nook closing member (1) are arranged, material is the 1Cr18Ni9Ti stainless steel pipe, and is furnished with the further chromed needle stand of outer surface (6) (7) after the nickel plating separately.Needle tubing (2) external diameter is 0.16 centimetre, desirable 6 to 10 centimetres of length, and the single sharpened end that head front end system is at 45 is so that needle tubing (2) can arrive diseased region through subcutaneous tissue smoothly.Nook closing member (1) external diameter is 0.10 centimetre, and length can correspondingly be got 7.5 to 11 centimetres.And make the hollow body that the tip has hollow hook-shaped parting tool (4).During operation nook closing member (1) is put into needle tubing (2), when needle tubing (2) arrives diseased region, nook closing member (1) is continued to push ahead, make nook closing member (1) tip stretch out about 1.5 centimetres or 1.0 centimetres of needle tubing (2) front end, nook closing member (1) is retreated in the needle tubing (2), the hook-shaped parting tool (4) of nook closing member this moment (1) cuts mutually with needle tubing (2) front end and obtains the pathological tissues piece again.Because the needle stand (7) of nook closing member (1) end has the negative pressure-pumping of syringe, and the pathological tissues piece that cuts down is inhaled in nook closing member (1) pipe.This is cut and inhales two purpose meedle and comprise that also can make straight skidding for one of the assembling of needle tubing (2) circumferential surface regulates, and by the depth of needle positioning sleeve (3) of annular knurl screw knob (5) stop, and this structure can be according to the fixing degree of depth of inserting needle of different use objects.
Cut the suction two purpose meedle and study, prove and carry out pathologic finding accuracy height, can treat, be specially adapted to be close to the peripheral lump pathological changes of thoracic wall or close thoracic wall the pathological tissues dabbling drug through clinical use.
Claims (1)
1, the suction two purpose meedle is cut in a kind of aspiration biopsy of pneumochirurgia apparatus, has needle tubing and nook closing member partly.It is characterized in that: nook closing member (1) is a hollow body, and front end has solid hook-shaped parting tool (4); Needle tubing (2) head is the single sharpened end of 45 ° of shapes, and is equipped with one at the circumferential surface of needle tubing (2) and can makes straight skidding and regulate, and by the depth of needle positioning sleeve (3) of annular knurl screw knob (5) stop.
