[0038] By opening the first cylinder 32, the first cylinder 32 can drive the puncture assembly 4 to move up and down during the extension and retraction process, thereby achieving puncture of the patient, and the output end of the first cylinder 32 slides with the slide rail 33 through the first guide wheel 35, so that the puncture assembly 4 will not deviate during puncture, and the accuracy is higher.

[0039] See also Figures 1 to 4 The puncture assembly 4 includes a second cylinder 41, a first mirror frame 42, a second mirror frame 43, a positioning light source 44, a first mirror body 45, a second mirror body 46 and a puncture needle 47. The output end of the first cylinder 32 is provided with a first groove, the second cylinder 41 is vertically fixedly arranged in the first groove, and the output end of the second cylinder 41 is provided with a second groove. The first mirror frame 42 is L-shaped and fixedly arranged on the left side of the output end of the second cylinder 41.

The plug 474 is fixedly arranged at the lower end of the core rod 473. The valve plate 475 is fixedly arranged at the lower end of the liquid collection area and is located between the plug 474 and the easy-folding part. The valve plate 475 includes a ring body and a sheet body. The sheet bodies are multiple and fan-shaped. One end of the multiple sheet bodies is fixedly connected to the inner side of the ring body. Two adjacent sheet bodies are fitted together. The sheet body is made of memory metal.

[0040] By arranging the second cylinder 41, the first mirror frame 42, the second mirror frame 43, the positioning light source 44, the first mirror body 45, the second mirror body 46 and the puncture needle 47, the second cylinder 41 can drive the puncture needle 47 to penetrate into or be pulled out of the patient's body during the extension and retraction process. By turning on the positioning light source 44 and adjusting the first mirror body 45 and the second mirror body 46, the projection position of the positioning light source 44 and the puncture needle 47 on the horizontal plane can be adjusted to coincide with each other by using the refraction of light, so as to assist the puncture needle 47 in locating the puncture site of the patient.

[0041] After the needle 471 is inserted into the patient's body, by opening the second cylinder 41, the second cylinder 41 can drive the core rod 473 to move vertically during the extension and retraction process, thereby pushing the contrast agent in the needle handle 472 into the patient's body, or extracting the accumulated fluid from the patient's body into the fluid collection area. Since the valve plate 475 is provided, the pressure generated during the extraction of the accumulated fluid will cause the valve plate 475 to open. After the valve plate 475 is closed, the accumulated fluid can be prevented from flowing out. After the accumulated fluid is collected, the medical staff can refrigerate the needle handle 472 with the accumulated fluid. At this time, the valve plate 475 will be in a closed state under low temperature, which can effectively prevent the accumulated fluid from being exposed.

[0042] Since an easy-to-break portion is provided at the needle handle 472 , after the puncture is completed, the needle handle 472 and the needle body 471 can be separated by breaking off the easy-to-break portion.
