Description
Technical Field
The utility model relates to the field of medical equipment, concretely relates to puncture auxiliary stay ware of CT guide.
Background
Clinical studies indicate that percutaneous aspiration biopsy can be used for timely and accurate diagnosis of tumor patients, and has important significance in controlling and preventing the incidence of tumors. The percutaneous aspiration biopsy under the guidance of a Computed Tomography (CT) scanner is a widely accepted method in clinic at present because of high spatial resolution, and a puncture needle is penetrated to a preset position under the guidance of CT and then cut to take out pathological change tissues for relevant analysis of pathology and the like. Although the puncture is performed in a minimally invasive manner, because a plurality of important organs such as large blood vessels and the like are arranged around a puncture path, the puncture is required to be accurate and quick, and repeated puncture is reduced to reduce the occurrence of complications such as pneumothorax, hemoptysis and the like of a patient.
The percutaneous aspiration biopsy under CT guidance is to scan a patient through CT, and to analyze an aspiration path, an aspiration depth, an injection point and the like avoiding important tissues such as a large blood vessel, a large air passage, bones and the like according to a scanned image. The operation doctor carries out percutaneous puncture needle insertion through local anesthesia in a sterile state, judges whether a puncture biopsy needle point reaches a designated position of a tumor according to a preset puncture path through CT scanning again after needle insertion, and needs to repeat puncture and CT scanning judgment until the needle point reaches a preset position if the puncture biopsy needle point does not reach the designated position of the tumor according to the preset puncture path.
Because the position is determined by means of CT scanning, and the CT scanning has certain radiation hazard, the operating doctor can not stay in the scanning room during scanning. Because the tail end of the biopsy needle is provided with the handle, the biopsy needle has certain weight, when CT scanning is carried out, under the suspended state and under the action of the gravity of the biopsy needle handle, the inclination angle of the biopsy needle during puncture can be increased, the needle point position of the puncture entering the human body of a patient can have certain displacement, the needle point can deviate from the preset position, and meanwhile, the probability of increasing complications due to the fact that the needle body is pulled by the human body is increased. If the position is deviated, the puncture and CT scanning judgment can be carried out again, and the biopsy gun can not be started to cut the tumor until the needle point is positioned at the preset position. When the puncture is performed, the puncture is performed according to a preset puncture path in many cases, but after the biopsy needle is released by the two hands of the operator, the needle point is deviated due to the gravity action of the handle of the biopsy needle, so that the puncture is required to be performed again, and the situation is troubled for many puncture doctors.
At present, a plurality of puncture positioners for supporting the biopsy needle are also arranged on the market, but some puncture positioners can be used only by modifying a CT examining table and cannot be directly used on CT. Some puncture positioners are placed beside the CT examining table independently and cannot move along with the CT table.
