[0030] The main body ring 1 comprises a first ring body 11 and a second ring body 12, the first ring body 11 is hinged with the second ring body 12, at least one clamping block 111 is integrally formed on the first ring body 11, a buckle 121 adapted to the clamping block 111 is installed on the second ring body 12, when the first ring body 11 is buckled with the second ring body 12, the ultrasonic probe 7 is fixed in the ring groove of the first ring body 11 and the second ring body 12, the main body ring 1 can be any shape ring body, in the embodiment, the main body ring 1 is preferably a circular ring body, which is convenient for medical staff to grasp, the hinge of the ring body and the buckling of the buckle 121 are both prior art and will not be described in detail.

[0031] Further, the inner wall of the ring groove of the first ring body 11 and the second ring body 12 is integrally formed with an anti-skid texture 3, the first ring body 11, the second ring body 12 and the anti-skid texture 3 are all medical grade rubber materials, which meet the hygiene standards of the operating environment and have certain deformation ability, and can be adapted to the installation and fixation of ultrasonic probes 7 of various models in cooperation with the anti-skid texture 3.

[0032] ReferenceFigure 1 And Figure 2 The puncture needle pushing mechanism 2 comprises a puncture fixing frame 21, a pushing assembly 22 and a locking assembly 23. The puncture fixing frame 21 is fixedly attached to the outer wall of the first ring body 11. The puncture fixing frame 21 is made of medical-grade rubber material, which meets the biological compatibility requirements, is easy to clean and disinfect, and meets the hygiene standards of the surgical environment. The pushing assembly 22 is installed in the puncture fixing frame 21 to install and fix the puncture needle and to push the puncture needle to achieve the puncture purpose. The locking assembly 23 is installed on the puncture fixing frame 21 to lock or release the pushing function of the pushing assembly 22, thereby ensuring the stability of the needle removal, biopsy gun installation and sampling process.

[0033] Referring to Figure 1 And Figure 2 The pushing assembly 22 comprises a knob gear 221, a driving gear 222, a transmission gear 223, a transmission screw 224 and a pushing slider 225. The knob gear 221 is rotatably installed on the puncture fixing frame 21 through the rotating shaft 4, and part of the knob gear 221 is located outside the puncture fixing frame 21. The driving gear 222 is coaxially fixed on the rotating shaft 4. The transmission screw 224 is rotatably installed in the puncture fixing frame 21. The transmission gear 223 is coaxially fixed on the transmission screw 224. The driving gear 222 and the transmission gear 223 are bevel gears that mesh with each other. The pushing slider 225 slides up and down on the puncture fixing frame 21 and is threadedly connected with the transmission screw 224. The puncture needle is fixedly inserted in the pushing slider 225. The pushing slider 225 is made of medical-grade rubber material and has elasticity, which can accommodate the insertion of various sizes of trocar 8. When performing the pushing operation, the doctor rolls the knob gear 221 by fingers, thereby driving the driving gear 222 to rotate. The driving gear 222 drives the transmission gear 223 meshing therewith to rotate. The transmission screw 224 rotates synchronously. The pushing slider 225 converts the spiral rotation of the transmission screw 224 into its linear motion through the limiting of the puncture fixing frame 21, thereby driving the movement of the trocar 8 to achieve puncture. The gear transmission mode can realize accurate control of the puncture depth.

[0034] Further, a pushing groove 211 is formed through the puncture fixing frame 21. The pushing slider 225 slides in the pushing groove 211. When the pushing slider 225 is at the starting end of the sliding stroke, the top end of the pushing slider 225 extends out of the puncture fixing frame 21. A clamping bolt 5 is screwed on the pushing slider 225. The clamping bolt 5 is inclined downward. When installing, the doctor inserts the trocar 8 into the pushing slider 225, and then tightens the clamping bolt 5 to lock the trocar 8, thereby reducing the possibility that the trocar 8 will slide in the pushing slider 225 due to the reaction force during puncture, which will affect the puncture.

[0035] Referring to Figure 2 And Figure 3The locking assembly 23 comprises a limiting cylinder 231, a cam 232, a button 233 and a pressing spring 234. The limiting cylinder 231 is installed in the puncture fixing frame 21 in an interference fit. One end of the button 233 is slidably arranged in the limiting cylinder 231, and the other end of the button 233 extends out of the outer wall of the puncture fixing frame 21. A plurality of protruding groove keys 2331 are integrally formed on the outer wall of the one end of the button 233 extending into the limiting cylinder 231. A guide rail groove 2311 matched with the protruding groove keys 2331 is formed on the inner wall of the limiting cylinder 231. The one end of the button 233 extending into the limiting cylinder 231 is integrally formed with a sawtooth structure 2332. The cam 232 is arranged in the button 233 at one end and extends out of the button 233 in the puncture fixing frame 21 at the other end. The cam 232 is integrally formed with a rack 2321 matched with the sawtooth structure 2332, so as to convert the linear motion of the button 233 into the rotary motion of the cam 232. A plurality of limiting tooth grooves 2312 matched with the rack 2321 and a plurality of recesses 2313 for the sliding insertion of the rack 2321 are circumferentially distributed on the limiting cylinder 231. One recess 2313 is arranged between two adjacent limiting tooth grooves 2312. The cam 232 is slidably arranged in the limiting cylinder 231 through the recess 2313 and the rack 2321. The one end of the cam 232 away from the button 233 is integrally formed with a limiting column 2322. The pressing spring 234 is arranged between the one end of the cam 232 away from the button 233 and the inner wall of the puncture fixing frame 21.

[0036] When the button 233 is pressed, the rack 2321 is matched with the limiting tooth groove 2312, the limiting column 2322 is arranged in the gap of the rotary gear 221, so as to limit the motion of the rotary gear, thereby fixing the position of the trocar 8, and reducing the possibility that the trocar 8 moves due to the accidental touch of the rotary gear by the medical staff during the operation. When adjustment is needed, the button 233 is pressed again, the cam 232 is rotated once, the rack 2321 and the cam 232 extend into the limiting cylinder 231, the limiting column 2322 is separated from the gap of the rotary gear, and then the medical staff can rotate the rotary gear. In the embodiment, the principle of the locking assembly 23 is similar to the structure of the retracting of a ballpoint pen, and will not be described in detail.

[0037] Further, the limiting groove 6 matched with the limiting column 2322 is arranged in the puncture fixing frame 21, so as to ensure the stability of the limiting column 2322 when the limiting column 2322 is arranged in the limiting groove 6. The reverse bevel matched with the inclined surface of the rack 2321 is integrally formed on the sidewall of the opening of the recess 2313 on the limiting cylinder 231, so as to ensure the smoothness when the state of the locking assembly 23 is switched.

[0038] The puncture sampling operation steps of the adjustable ultrasonic probe puncture support system are as follows:

[0039] (1) Patient position preparation: let the patient take supine or prone position, and determine the puncture site by ultrasound before operation, then disinfect and lay sterile drape;
