Problems solved by technology
[0004] Most of the existing puncture devices do not have the function of depth adjustment. When performing puncture, the puncture needle is manually inserted into the body by the doctor. On the one hand, the accuracy is limited, and on the other hand, the insertion speed is slow, which is very easy to bring adverse effects to the patient. mood

The invention relates to a medical instrument, in particular to an interventional department puncture device capable of adjusting puncture depth, which comprises a cylindrical shell with two through ends, and a top cover and a bottom cover are detachably arranged at the two ends of the shell respectively; the opening diameter of one end, facing the top cover, of the shell is larger, and the opening diameter of the other end is smaller; a needle cylinder capable of moving in the axial direction of the shell is coaxially arranged in the shell, a puncture needle is coaxially fixed to the side, facing the bottom cover, of the needle cylinder, and the puncture needle is communicated with the interior of the needle cylinder. An elastic needle withdrawing mechanism is arranged between the needle cylinder and the top cover, and a switch assembly is further arranged between the elastic needle withdrawing mechanism and the shell. Through the cooperation of the switch assembly and the elastic needle withdrawing mechanism, after the bottom cover is detached, the puncture needle can be quickly inserted into a human body, the reaction time left for a patient is extremely short, and therefore pains in the puncture process, including psychological and physiological pains, are eliminated, and the arranged adjusting assembly can adjust the depth of single puncture.
Description
technical field [0001] The invention relates to a medical device, in particular to an interventional puncture device with adjustable puncture depth. Background technique [0002] Interventional puncture refers to a new technology for further clinical diagnosis and treatment under the guidance of imaging and the guidance of ultrasound probes. Ultrasound interventional puncture guidance can complete various puncture biopsies, and can perform suction and intubation on some lesions , Injection of drugs and other operations can play a very good complementary role with surgical operations that are difficult to reach or areas that are restricted areas of surgery. [0003] At present, needle biopsy generally takes 30 minutes to 1 hour. Check whether the operation is smooth, whether the mass is limited, and whether the puncture is successful. The specific steps are divided into the first step, local anesthesia after color ultrasound positioning. In the second step, the puncture ne...
