Abstract

The invention discloses a puncture frame device. The device comprises a fixing frame device which is detachably arranged on a shell of an ultrasonic probe, a puncture needle fixing device which is arranged on the fixing frame device and a fixing sheet which is arranged on the fixing frame device, wherein a puncture needle insertion hole which is matched with a puncture needle and axially penetrates is formed in the puncture needle fixing device; a lateral concave surface is arranged on one side of the puncture needle insertion hole; the width of a cross section on which the lateral concave surface is intersected with the puncture needle insertion hole is more than or equal to the diameter of the puncture needle; one end of the fixing sheet acts on the fixing frame device, and the other end of the fixing sheet acts on an elastic piece of the fixing sheet; and under the elastic state of the elastic piece, one end of the fixing sheet is overlapped on the lateral concave surface, and the fixing sheet forms a puncture needle guide hole together with the puncture needle insertion hole. By the device, the aim that the puncture needle can be conveniently separated from the puncture frame device under the precondition that the puncture needle is not removed and the parts of a puncture frame are not required to be detached in the clinical puncture process, namely after the puncture needle is inserted into a human body is fulfilled.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a puncture rack device. Background technique [0002] At present, in the field of medical devices, ultrasonic probes are widely used. In clinical use, a puncture frame is generally installed on the ultrasonic probe, and then the puncture needle is fixed and guided by the puncture frame, and the target tissue in the patient is obtained through the puncture needle. Or inject medical agents into the patient's body through a puncture needle. During the clinical use of the puncture rack device, after the puncture needle is inserted into the human body, in order to stably obtain the target tissue in the patient's body, it is usually required to separate the puncture needle from the puncture rack device without removing the puncture needle. [0003] In the document of Chinese Patent No. 200520120095.7, a puncture frame device that facilitates the guidance and separation of ...
