DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technical personnel in this field without making creative work are within the scope of protection of the present invention.

[0029] Reference Figure 1-Figure 4 The adjustable ultrasound probe puncture support system includes a main bracelet 1 and a puncture needle pushing mechanism 2. The main bracelet 1 is an openable and closable annular structure for installing and fixing the ultrasound probe 7; the puncture needle pushing mechanism 2 is installed on the side wall of the main bracelet 1 for pushing and puncturing the puncture needle, as well as fixing it after puncture to facilitate the subsequent removal of the needle core and installation of the biopsy gun.

[0030] The main bracelet 1 includes a first ring body 11 and a second ring body 12. The first ring body 11 is hinged to the second ring body 12. At least one snap-on block 111 is integrally formed on the first ring body 11. The second ring body 12 is equipped with a snap-on 121 that is snap-on and adapted to the snap-on block 111. When the first ring body 11 and the second ring body 12 are snapped together, the ultrasonic probe 7 is fixed in the annular grooves of the first ring body 11 and the second ring body 12. The main bracelet 1 can be a ring body of any shape. In this embodiment, the main bracelet 1 is preferably a circular ring body, which is convenient for medical staff to grasp. The hinge of the ring body and the snap-on 121 are both existing technologies and will not be described in detail.

[0031] Furthermore, the inner walls of the ring grooves of the first ring body 11 and the second ring body 12 are integrally formed with anti-slip textures 3. The first ring body 11, the second ring body 12 and the anti-slip textures 3 are all made of medical-grade rubber materials, which meet the hygiene standards of the surgical environment and have a certain degree of deformation ability. Together with the anti-slip textures 3, they can be adapted to the installation and fixation of various types of ultrasound probes 7.

[0032] Reference Figure 1 and Figure 2 The puncture needle pushing mechanism 2 includes a puncture fixing frame 21, a pushing component 22 and a locking component 23. The puncture fixing frame 21 is bonded and fixed on the outer wall of the first ring body 11. The puncture fixing bracket is made of medical-grade rubber material, which meets the requirements of biocompatibility, is easy to clean and disinfect, and meets the hygiene standards of the surgical environment. The pushing component is installed in the puncture fixing frame 21 to install and fix the puncture needle and push the puncture needle to achieve the puncture purpose. The locking component 23 is installed on the puncture fixing frame 21 to lock or release the pushing function of the pushing component to ensure the stability of the needle removal, biopsy gun installation and sampling process.

[0033] Reference Figure 1 and Figure 2 The pushing assembly includes 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 mounted on the puncture fixing frame 21 through the rotating shaft 4. The knob gear 221 is partially 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 mounted inside 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 mutually meshing bevel gears. The pushing slider 225 slides and rises and falls on the puncture fixing frame 21 and is threadedly connected with the transmission screw 224. The puncture needle is inserted and fixed on the pushing slider 225. The pushing slider 225 is made of medical-grade rubber material and is elastic. It can adapt to the insertion of trocars 8 of various sizes. When performing the pushing operation, the doctor rolls the knob gear 221 with his fingers, thereby driving the active gear 222 to rotate, and the active gear 222 drives the transmission gear 223 meshing with it to rotate, and the transmission screw 224 rotates synchronously. The pushing slider 225 converts the spiral rotation of the transmission screw 224 into its own linear motion through the limit of the puncture fixing frame 21, thereby driving the movement of the trocar 8 to achieve puncture, and the gear transmission method can achieve precise control of the puncture depth.

[0034] Furthermore, a pushing groove 211 is formed through the puncture fixing frame 21, and a pushing slider 225 is slidably arranged in the pushing groove 211. When the pushing slider 225 is located at the starting end of the sliding stroke, the top end of the pushing slider 225 extends out of the fixing frame. A tightening bolt 5 is screwed on the pushing slider 225, and the tightening bolt 5 is tilted downward. During installation, the doctor inserts the cannula needle 8 into the pushing slider 225, and then locks the cannula needle 8 by tightening the tightening bolt 5 to reduce the possibility that the cannula needle 8 slides in the pushing slider 225 due to the reaction force during puncture, affecting the puncture.

[0035] Reference Figure 2 and Figure 3The locking assembly 23 includes a limiting cylinder 231, a cam 232, a button 233 and a tightening spring 234. The limiting cylinder 231 is inserted and installed in the puncture fixing frame 21 by interference fit. One end of the button 233 is slidably penetrated 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 raised groove keys 2331 are integrally formed on the outer wall of the end of the button 233 extending into the limiting cylinder 231. A guide groove 2311 adapted to the raised groove key 2331 is provided on the inner wall of the limiting cylinder 231. A sawtooth structure 2332 is integrally formed on the end of the button 233 extending into the limiting cylinder 231. One end of the cam 232 is penetrated in the button 233, and the other end extends out of the button 233 and is located in the puncture fixing frame 21. The cam 232 is integrally formed with a rack 2321 that is plugged and matched with the sawtooth structure 2332 to convert the linear motion of the button 233 into the rotational motion of the cam 232. A plurality of limiting tooth grooves 2312 that are plugged and matched with the rack 2321 and a plurality of grooves 2313 for the rack 2321 to be slidably inserted are distributed on the circumference of the limiting cylinder 231. A groove 2313 is provided between two adjacent limiting tooth grooves 2312. The cam 232 extends into the limiting cylinder 231 through the sliding cooperation between the groove 2313 and the rack 2321. A limiting column 2322 is integrally formed at one end of the cam 232 away from the button 233. A pressing spring 234 is pressed between the end face of the cam 232 that is away from the button 233 and the inner wall of the puncture fixing frame 21.

[0036] By pressing the button 233, when the rack 2321 is plugged into the limiting tooth groove 2312, the limiting column 2322 is inserted into the tooth gap of the knob gear 221 to limit the movement of the rotating gear, thereby fixing the position of the cannula needle 8, reducing the possibility of medical staff accidentally touching the rotating gear during operation and causing the cannula needle 8 to move; when adjustment is needed, only the button 233 needs to be pressed again, and the cam 232 can be rotated once, the rack 2321 and the cam 232 extend into the limiting cylinder 231, and the limiting column 2322 also escapes from the tooth gap of the rotating gear, so that the medical staff can rotate the rotating gear. In this embodiment, the principle of the locking assembly 23 is similar to the structure of a ballpoint pen that is pressed and retracted, and no further elaboration is made.

[0037] Furthermore, a limiting groove 6 which is plugged and matched with the limiting column 2322 is opened in the puncture fixing frame 21 to ensure the stability of the limiting column 2322 when it is limited, and an inverted slope which is matched with the slope of the rack 2321 is integrally formed on the side wall at the opening of the groove 2313 on the limiting cylinder 231 to ensure the smoothness of the locking assembly 23 when switching the state.

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

[0039] (1) Patient position preparation: The patient is placed in a supine or prone position. The puncture site is determined by ultrasound before the operation, and then disinfected and covered with sterile towels;

[0044] (6) Replace the biopsy gun and take samples: Use the other hand to remove the needle core of the cannula needle 8, install the biopsy gun, and complete tissue sampling.

[0045] The above is only a preferred embodiment of the present invention, and is not any formal or substantial limitation of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and supplements without departing from the present invention, and these improvements and supplements should also be regarded as the protection scope of the present invention.
