Abstract
The utility model relates to a suction and cutting needle for percutaneous biopsy of a lung, which is composed of a trocar, a taking and checking needle and a lifted needle. The taking and checking needle is arranged in the trocar. The lifted needle is used for taking out tissues in the trocar. Tissue section specimens and specimens used as cytology and bacteriology smears and culture can be obtained through the taking and checking needle and suction and cutting tissues of a suction and cutting hole which is arranged on the trocar. The utility model not only has small damage of the tissue, but also is hard to cause a complication. Because the utility model can be used for needle inserting many times through the taking and checking needle in the trocar and samples can be taken out in multi-direction through the suction and cutting hole, the positive rate of the diagnosis to pulmonary diseases is high. The success ratio of the percutaneous biopsy of the lung can reach 95%.
Description
This utility model relates to a kind of apparatus that takes out medium in the human body, particularly a kind of percutaneous lung biopsy suction and cutting needle.
Usually, the apparatus that is adopted in the biopsy of percutaneous lung puncture is generally needle sets such as the comparatively single puncture needle of function, cutting needle, trepan pin.Puncture needle is to lean on simple vacuum suction by the needle body that penetrates focus, tissue is entered in the pin, because this pin inserting needle once only can be drawn materials once, and organize the taking-up amount less, so only can carry out cytoscopy, can not carry out pathologic finding, if draw materials repeatedly, tissue injury is bigger again, easily forms complication such as pneumothorax, hemorrhage, puncture needle track transfer.The trepan pin is to go into focus by a trocar puncturing, drills through tissue with spiral sample drill bit, though it can carry out pathologic finding, it is few to drill through tissue, and bigger to the damage of tissue, often organizes pressurized admittedly, and cytomorphosis causes the pathological diagnosis difficulty, and can not repeat.Cutting needle is to utilize a bodkin to penetrate focus, the crochet hook that inserts in the pin stamen hooks up tissue, though it is less to tissue injury, but have cut and organize less, shortcoming that facet is little, and both needle sets of back all do not possess the vacuum suction function, get the inspection shortcoming that success rate is low, complication is high but no matter adopt which kind of pin type all to have.
The purpose of this utility model is to provide a kind of percutaneous lung biopsy suction and cutting needle, and it not only possesses suction, cuts two kinds of functions of tissue, and easy and simple to handle, and tissue injury is little, gets inspection success rate height, and is difficult for leading to complications.
Its concrete solution is: by the trocar, get inspection pin, eject pin three parts and constitute, getting inspection pin needle body is arranged in the trocar, eject pin is arranged on to be got in the inspection pin, and not ipsilateral, the differing heights of getting inspection pin and trocar needle body bottom are provided with and can corresponding mutually suction cut the hole, the trocar and get inspection pin needle handle and be provided with and can make the trocar and get the inspection pin and inhale and cut the labelling that the hole coincides, the lateral wall subscript of the trocar is marked with inhales the cutting-in scale designation.The needle point position of the trocar is the inclined end face of a sealing, and the internal diameter on trocar needle handle top is greater than the internal diameter of needle handle bottom and needle body, get inspection pin needle body top and be set with a sealing ring, be used to get the sealing between the inspection pin and the trocar, the length of eject pin needle body is more than or equal to the length of getting the inspection pin.Inhale and cut under the overlapping situation in hole getting inspection pin and the trocar during use, be evacuated to negative pressure with syringe and cut the hole by suction and inhale, cut lesion tissue, after getting the inspection pin and taking out, the lesion tissue that different depth and position are inhaled, cut can be ejected by eject pin.
This utility model is easy and simple to handle, less to tissue injury, owing to possess suction, cut two kinds of functions, so both can obtain the born of the same parents that run business into particular one learns, the specimen of bacteriology's smear and cultivation, can obtain the tissue slice specimen again, again because can be by getting repeatedly inserting needle and by the trocar and get the suction that inspection is provided with on the pin and cut the multi-faceted sampling in hole of inspection pin in the trocar, so the positive rate to the pulmonary disease diagnosis is higher, and after puncture finishes, can in needle track, inject from body blood by the trocar, because blood coagulation, can reduce complication such as hemorrhage and pneumothorax, prevent and reduced the chance of needle track implantation, complication is significantly reduced, its percutaneous lung biopsy success rate can reach 95%.
In conjunction with the accompanying drawings this utility model is described in detail below by embodiment:
Fig. 1 is this utility model structural representation.
Fig. 2 is that the A of Fig. 1 is to view.
Fig. 3 is that the B of Fig. 1 is to view.
In the accompanying drawing, getting inspection pin (2) is arranged in the trocar (4), eject pin (1) is arranged on to be got in the inspection pin (2), get between inspection pin (2) and the trocar (4) and eject pin (1) and get to examine to be between the pin (2) and be slidingly matched, eject pin (1) needle body length with get inspection pin equal in length, get inspection pin (2) needle body top and be bonded with a sealing ring (3), be used to get the sealing between the inspection pin (2) and the trocar (4), the not ipsilateral of getting inspection pin (2) and the trocar (4) two needle body bottoms is provided with the suction of mutual correspondence and cuts hole (g), (f) and (e), (d), the needle point position of the trocar (4) is one to be 45 ° inclined end face.
During use, take out eject pin (1), by pointer sign (a) and (b), making the suction of getting on the inspection pin (2) and the trocar (4) cut the hole does not coincide, localised puncture is to focus under X line or B ultrasonic, rotation is got the inspection pin and is made to get to inhale on inspection pin and the trocar by the pointer sign and cut hole (g) and (f), (e) overlap with (d), adopt syringe will get inspection pin inner chamber and be evacuated to negative pressure, its lesion tissue will by suction cut the hole enter get the inspection pin in, extract thereupon and get inspection pin (2), and release lesion tissue with eject pin (1), can repeatedly insert in case of necessity and get inspection pin and rotary sleeve bobbin and change direction and inhale repeatedly, cut.
Claims (3)
1. percutaneous lung biopsy suction and cutting needle, it is characterized in that getting inspection pin (2) needle body is arranged in the trocar (4), eject pin (1) is arranged on to be got in the inspection pin (2), and get the not ipsilateral of inspection pin (2) and the trocar (4) needle body bottom and highly be provided with the verify of getting of correspondence mutually, the needle point position of the trocar (4) is a sealing inclined end face, gets inspection pin (2) needle body top and is set with a sealing ring (3).
2. percutaneous lung biopsy suction and cutting needle according to claim 1, the lateral wall subscript that it is characterized in that the trocar (4) are marked with inhales the cutting-in scale designation, the trocar (4) and get inspection pin (2) needle handle and be provided with to inhale and cut hole registration mark (b), (a).
3. percutaneous lung biopsy suction and cutting needle according to claim 1 is characterized in that the trocar (4) and gets between inspection pin (2) and eject pin (1) is slidingly matched with getting to examine to be between the pin (2).
