The invention discloses a liver puncture guiding device for autoimmune liver disease and hepatitis examination. The device comprises a first reaming plate, a second reaming plate, two clamping strips,four anti-skid edges, a torsional spring and a guide assembly, wherein the front side of the top end of the first reaming plate is rotationally connected with the front side of the bottom end of thesecond reaming plate through a pin shaft; the two clamping strips are fixedly connected to the front side of an inner cavity of the first reaming plate and the front side of an inner cavity of the second reaming plate correspondingly; every two of the four anti-skid edges form a group and are fixedly connected to the front side and the rear side of the inner wall of each clamping strip; the torsional spring is connected to the outer wall of the pin shaft in a sleeving mode; one end of the torsional spring is connected with the inner wall of the first reaming plate in a clamped mode, and the other end of the torsional spring is connected with the inner wall of the second reaming plate in a clamped mode; and the guide assembly is detachably arranged on the rear side of the inner wall of thefirst reaming plate. According to the liver puncture guiding device for the autoimmune liver disease and hepatitis examination, when a puncture needle is guided inwards, the meat tissue can be expanded more deeply, so that the puncture needle can be guided inwards conveniently; and the device is simple to operate and stable to support.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a liver puncture guiding device for autoimmune liver disease hepatitis inspection. Background technique [0002] Liver puncture is a method of liver biopsy. Because it is very traumatic to the liver puncture, it will make the patient experience extremely bad when it is implemented, and it is not easy to accept. Therefore, liver puncture is not a routine examination. method, but because of its accuracy and efficiency of biopsy is a good inspection method, so there is a need for research; [0003] During the puncture process, the medical staff needs to hold the puncture needle in one hand. When performing hepatobiliary puncture on the patient, two doctors or nurses are often required to assist each other to complete it. When the puncture needle is inserted into the patient, one of the doctors or nurses needs to Hold the puncture needle after insertion so that another docto...
