Detailed Description
The utility model is described in further detail below with reference to the attached drawings and specific examples:
referring to fig. 1-showing, the present embodiment comprises an annular base 1, a puncture needle holder 2 movably mounted in the annular base 1, and an ultrasonic probe holder 3 mounted on the outer side wall of the annular base 1.
The ultrasonic probe placing frame 3 comprises an arc-shaped supporting part 31 and a probe placing part 32 fixedly connected with one end of the arc-shaped supporting part 31; the probe placing part 32 is located right above the annular base 1, so that the ultrasonic probe can be opposite to the skin of a patient, when the ultrasonic probe is clamped and fixed on the probe placing part 32, the probe head of the ultrasonic probe can be in vertical contact with the skin of a human body generally, ultrasonic detection cannot be affected, and enough gaps remain between the probe head and the skin of the human body, so that the puncture needle can puncture the skin.
The needle frame comprises a base 21 and a supporting frame 22 movably connected above the base 21.
The upper end face of the annular base 1 is fixedly provided with a circle of sliding groove 11, the lower end face of the needle frame base 21 is provided with a sliding block 212, and the sliding block 212 is clamped in the sliding groove 11. The outer side wall of the annular base 1 is fixedly provided with a circle of sliding rail 12 for the annular sliding of the ultrasonic probe placing frame, and the ultrasonic probe placing frame 3 is arranged in the sliding rail 12. When the ultrasonic probe placing frame 3 rotates around the annular base 1 along the X1 direction, the central position of the probe placing part 32 is unchanged all the time, and the angle right above the center of the annular base 1 is kept, so that the normal detection guide of the ultrasonic probe is not influenced in the rotating process. In the use process, the ultrasonic probe holder 3 can be flexibly rotated, so that the puncture needle holder 2 is prevented from being influenced by the ultrasonic probe holder. When the puncture needle frame 2 is flexibly rotated around the annular base 1 along the X3 direction through the annular base 1, the needle head of the puncture needle always aims at the center of a circle to puncture, when the space for entering is limited by the rib or the iliac crest, the puncture needle can deviate by a slight angle around the puncture point, the rib or the iliac crest is bypassed, the needle inlet point is more flexibly selected, and the puncture accuracy is improved.
