Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically a medical ultrasonic lithotripsy probe. Background Technology

[0002] Ultrasonic lithotripsy utilizes electrical energy converted into sound waves. These sound waves generate mechanical vibration energy within the ultrasonic transducer, which is transmitted to the ultrasonic probe via ultrasonic electrodes, causing its tip to vibrate longitudinally. When it comes into contact with a hard stone, it produces a lithotripsy effect, but does not damage soft tissues.

[0003] The existing stone probe has a single, integral rod, which means that the angle of the rod head on one side cannot be adjusted. This makes it difficult to aim the rod head at the target stone when breaking it up, making it inconvenient to use and less efficient at breaking up stones. As a result, patients experience more pain during stone breaking up treatment.

[0004] Therefore, in order to solve the above problems, the present invention proposes a medical ultrasonic lithotripsy probe. Summary of the Invention

A handle is fixedly connected to one side of the rod body, and a flexible tube is fixedly connected to the other side of the rod body. A rod head is fixedly connected to one side of the flexible tube. The handle has several sliding grooves, and a guide groove is provided inside the handle corresponding to each sliding groove position. A lubrication mechanism is provided on one side of the handle corresponding to each sliding groove position. A transmission mechanism is provided inside each guide groove. A mounting plate is fixedly connected to the rod head. The mounting plate has several mounting slots on one side. On the other side of the mounting plate, a pulling block is slidably connected to each mounting slot. A symmetrically arranged support block is fixedly connected to one side of each pulling block. A support wheel is rotatably connected to each support block. A symmetrically arranged rotating rod is rotatably connected inside each mounting slot. A clamping plate is fixedly connected to each rotating rod. An oblique groove is formed on each clamping plate. An oblique support groove is formed inside each clamping plate at the position corresponding to the oblique groove. A clamping mechanism is provided on one side of each clamping plate. A connecting ring is slidably connected to the rod head. A movable ring is fixedly connected to one side of the connecting ring.

[0007] Specifically, the lubrication mechanism includes a through groove, and symmetrically arranged vertical rods are rotatably connected inside the through groove. Each vertical rod is fixedly connected to a lubrication roller, and each lubrication roller is provided with a clamping groove.

[0008] Specifically, the through grooves in the four lubrication mechanisms are respectively opened at the positions of the corresponding slide grooves on one side of the grip, and the through grooves in the four lubrication mechanisms are in a state of communication with the four slide grooves.

[0009] Specifically, the transmission mechanism includes a moving block and a guide rod. A transmission block is fixedly connected to the moving block. A threaded groove is opened on the transmission block. A bolt is threadedly connected to the threaded groove. A frosting block is fixedly connected to the bolt.

[0010] Specifically, the moving blocks in the four transmission mechanisms are slidably connected to the inside of the four guide grooves, the guide rods in the four transmission mechanisms are fixedly connected to the inside of the four guide grooves, the moving blocks in the transmission mechanisms are slidably connected to the guide rods, the frosted blocks in the transmission mechanisms have frosted textures, and the bolts in the four transmission mechanisms are slidably sleeved together with the four second fixing rings.

[0011] Specifically, the clamping mechanism includes C-shaped plates, with a fixing rod fixedly connected to the middle position of the opposite surfaces of the two C-shaped plates, an arc-shaped block fixedly connected to one side of the opposite surfaces of the two C-shaped plates, and symmetrically arranged compression springs fixedly connected between the two arc-shaped blocks.

[0012] Specifically, the C-shaped plates in the four clamping mechanisms are fixedly connected to one side of the clamping plate, the compression springs in the clamping mechanisms are all in a tightly contracted state, and the fixing rods in the four clamping mechanisms are respectively clamped and connected to the four first fixing rings.

[0013] Specifically, the support blocks are slidably connected inside the inclined grooves, the support wheels are slidably connected inside the inclined support grooves, one side of each support block is located inside the mounting groove, and the other side of the pulling block is fixedly connected to the moving ring.

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0020] like Figures 1-6As shown, the medical ultrasonic lithotripsy probe of the present invention includes a rod body 1, a first fixing ring 2, and a second fixing ring 3. A tightening rope 4 is fixedly connected between the first fixing ring 2 and the second fixing ring 3. A handle 5 is fixedly connected to one side of the rod body 1, and a flexible tube 6 is fixedly connected to the other side of the rod body 1. A rod head 7 is fixedly connected to one side of the flexible tube 6. The handle 5 has several grooves 8, and a guide groove 9 is provided inside the handle 5 corresponding to each groove 8. A lubrication mechanism 10 is provided on one side of the handle 5 corresponding to each groove 8. A transmission mechanism 11 is provided inside each guide groove 9. A mounting plate 12 is fixedly connected to the rod head 7, and a series of mounting holes are provided on one side of the mounting plate 12. The mounting slot 13 has a pull block 14 slidably connected to each mounting slot 13 on the other side of the mounting plate 12. Each pull block 14 has a symmetrically arranged support block 15 fixedly connected to one side. Each support block 15 has a support wheel 16 rotatably connected to it. Each mounting slot 13 has a symmetrically arranged rotating rod 17 rotatably connected to it. Each rotating rod 17 has a clamping plate 18 fixedly connected to it. Each clamping plate 18 has an oblique groove 19. Each clamping plate 18 has an oblique support groove 20 corresponding to the oblique groove 19. Each clamping plate 18 has a clamping mechanism 21 on one side. Each rod head 7 has a connecting ring 22 slidably connected to it. Each connecting ring 22 has a moving ring 23 fixedly connected to one side.

[0021] Specifically, the lubrication mechanism 10 includes a through groove 101, and symmetrically arranged vertical rods 102 are rotatably connected inside the through groove 101. Lubrication rollers 103 are fixedly connected to each vertical rod 102, and clamping grooves 104 are opened on each lubrication roller 103.

[0022] Specifically, the through grooves 101 in the four lubrication mechanisms 10 are respectively opened on one side of the handle 5 at the position corresponding to each slide groove 8. The through grooves 101 in the four lubrication mechanisms 10 are in a state of communication with the four slide grooves 8, so that the tightening rope 4 passes through the through groove 101 and then enters the slide groove 8.

[0023] Specifically, the transmission mechanism 11 includes a moving block 111 and a guide rod 112. A transmission block 113 is fixedly connected to the moving block 111. A threaded groove 114 is provided on the transmission block 113. A bolt 115 is threadedly connected to the threaded groove 114. A sanding block 116 is fixedly connected to the bolt 115.

[0024] Specifically, the moving blocks 111 in the four transmission mechanisms 11 are slidably connected to the interior of the four guide grooves 9, and the guide rods 112 in the four transmission mechanisms 11 are fixedly connected to the interior of the four guide grooves 9. The moving blocks 111 and guide rods 112 in the transmission mechanism 11 are slidably connected. The frosted blocks 116 in the transmission mechanism 11 have a frosted texture. The bolts 115 in the four transmission mechanisms 11 are slidably sleeved with the four second fixing rings 3. The bolts 115 and the second fixing rings 3 are slidably sleeved together, which facilitates pulling the entire tightening rope 4 through the second fixing rings 3.

[0025] Specifically, the clamping mechanism 21 includes a C-shaped plate 211, a fixing rod 212 is fixedly connected to the middle position of the opposite surfaces of the two C-shaped plates 211, an arc-shaped block 213 is fixedly connected to one side of the opposite surfaces of the two C-shaped plates 211, and a symmetrically arranged compression spring 214 is fixedly connected between the two arc-shaped blocks 213.

[0026] Specifically, the C-shaped plates 211 of the four clamping mechanisms 21 are respectively fixedly connected to one side of the clamping plate 18, the compression springs 214 in the clamping mechanisms 21 are all in a tightly contracted state, and the fixing rods 212 in the four clamping mechanisms 21 are respectively clamped and connected to the four first fixing rings 2, so that when the tightening rope 4 is pulled, the entire rod head 7 can be pulled through the fixing rods 212.

[0027] Specifically, the support blocks 15 are slidably connected inside the inclined grooves 19, and the support wheels 16 are slidably connected inside the inclined support grooves 20. One side of each support block 15 is located inside the mounting groove 13, and the other side of the pulling block 14 is fixedly connected to the moving ring 23. The inclined grooves 19 and the inclined support grooves 20 are in a communicating state, and the support wheels 16 are slidably connected to the inclined support grooves 20, which facilitates the sliding of the support wheels 16 inside the inclined support grooves 20.

[0028] When using the device, if the rod head 7 needs to be pulled and adjusted to a certain angle, the medical staff first moves the bolt 115 to one side using the abrasive block 116. This movement of the bolt 115 causes the second fixing ring 3 to move, and simultaneously, the bolt 115 also moves the transmission block 113 and the moving block 111. The movement of the transmission block 113 and the moving block 111 is guided by the guide rod 112. When the second fixing ring 3 moves to one side, it pulls the tightening rope 4. This movement also acts on the lubrication roller 103, causing the lubrication roller 103 and the vertical rod 102 to rotate passively, making the movement of the tightening rope 4 smoother. When the tightening rope 4 moves to one side, it moves the first fixing ring 2. Since the first fixing ring 2 is clamped and connected to the fixing rod 212, the tension of the first fixing ring 2 acts on the fixing rod 212, causing the fixing rod 212 to move... The moving rod head 7 bends and changes angle, which is achieved through the flexible hose 6. The flexible hose 6 is flexible and can be used with the rod head 7 for angle adjustment. When disinfecting the rod body 1, first pull the connecting ring 22 to one side. The connecting ring 22 will move the moving ring 23, which in turn will move the pulling block 14. The pulling block 14 will then move the support block 15 and the support wheel 16. The support block 15 slides inside the inclined groove 19, while the support wheel 16 slides inside the inclined support groove 20. The support wheel 16 will slowly move from the deepest part of the inclined support groove 20 to a shallower part. When the support wheel 16 reaches a shallower position in the inclined support groove 20, it will slowly open the top of the clamping plate 18. When the clamping plate 18 opens, it will also open the C-shaped plate 211. Figure 4 As shown, the rotation and opening of the two C-shaped plates 211 will also stretch the compression spring 214 through the arc block 213. At the same time, the two C-shaped plates 211 will drive the two fixing rods 212 to open, no longer clamping the first fixing ring 2, releasing the position limitation of the first fixing ring 2, and then each first fixing ring 2 can be removed. Next, each bolt 115 can be turned out of the threaded groove 114. Then the position limitation of each second fixing ring 3 is also released. At this time, the tightening rope 4 is removed, and the rod body 1 can be disinfected normally. After the rod body 1 is disinfected, a new tightening rope 4 can be replaced to continue working. It should be noted that both the first fixing ring 2 and the second fixing ring 3 can be deformed. When the second fixing ring 3 needs to be passed through the through groove 101, the second fixing ring 3 can be flattened to pass through.
