Description

Technical Field

[0001] This application relates to the field of ultrasonic diagnosis and treatment technologies, and particularly to a silicone water sac for drainage. Background Art

[0002] With the development of focused ultrasound technology, high-intensity focused ultrasound knives have become one of the important clinical treatment devices. Using a focused ultrasound knife for cancer treatment has become an important medical means, known as "bloodless surgery" and "cutting tumors through the abdomen".

[0003] When performing ultrasound knife treatment, the treatment position is usually marked on the patient's body surface. Generally, the patient will receive local anesthesia to relieve discomfort during the treatment process. Then, the doctor will accurately locate the treatment area to ensure precise release of ultrasonic energy. Next, degassed water is prepared using a degassing mechanism and filled into the silicone water sac. Relying on the elasticity of the water sac, good coupling between the ultrasound knife treatment head and the skin can be maintained. During treatment, the HIFU system will release high-intensity ultrasonic energy to the target tissue area through a focused ultrasonic transmitter. This energy will form a high-temperature area at a specific depth in the body to destroy or treat the target tissue. At this time, the doctor will adjust the parameters of the ultrasonic waves according to real-time imaging and feedback information, thus completing the ultrasound knife treatment.

[0004] Existing silicone water sacs are generally connected to a bracket through multiple bolts to ensure the stability of the silicone water sac. This is simple and easy to implement. However, since the cleanliness of the silicone water sac affects the transmission efficiency of ultrasonic energy, if there are impurities or dirt inside the water sac, it may cause attenuation or scattering of ultrasonic energy. Therefore, the silicone water sac needs to be regularly maintained and cleaned. After the maintenance and cleaning are completed, it is necessary for the staff to hold the water sac while using bolts to fix the water sac to the bracket, which increases the work intensity of the staff and is rather inconvenient. Content of the Utility Model

[0014] By adopting the above technical solution, pressing the driving head drives the special-shaped block one downward, and the downward movement of the special-shaped block one will cause the two special-shaped blocks on both sides to move to both sides.

[0015] Furthermore, dovetail blocks are fixedly connected to both sides of the first special-shaped block. Dovetail grooves are formed on the mutually approaching surfaces of the two special-shaped blocks on both sides. The dovetail blocks and the dovetail grooves are adapted in shape, and the dovetail blocks are slidably connected to the dovetail grooves.

[0023] 2. In the present application, when pressing the driving head, the two special-shaped blocks on both sides move away from each other and compress the spring, causing the spring to generate elastic potential energy. When the engaging block enters the engaging groove, no pressure is applied to the driving head anymore.

[0030] The following will Figures 1-4 make a further detailed description of the present application in conjunction with the attached drawings.

[0031] An embodiment of the present application discloses a silicone water sac for drainage.

[0032] Referring to Figure 1 and Figure 2 , a silicone water sac for drainage includes a silicone water sac body 3. A connecting block 2 is fixedly connected to the top of the silicone water sac body 3. The connecting block 2 is arranged in a ring shape. A bracket 1 is fixedly connected to the top of the connecting block 2. The inside of the bracket 1 is hollow. A B-ultrasound probe 4 is arranged inside the bracket 1. The bottom end of the B-ultrasound probe 4 is fixedly connected to the silicone water sac body 3. A water inlet pipe 5 is arranged on one side inside the bracket 1, and a water outlet pipe 6 is arranged on the other side inside the bracket 1. The bottom ends of the water inlet pipe 5 and the water outlet pipe 6 are both communicated with the silicone water sac body 3. A plurality of fixing blocks 7 are fixedly connected to the outer sides of the bracket 1 and the connecting block 2 in an annular array. The fixing blocks 7 on the upper and lower sides are fixedly connected by bolts. Pre-fixing mechanisms are arranged on both sides of the bracket 1.

[0033] During the ultrasonic knife treatment, first, the silicone water sac body 3 needs to be fixed on the bracket 1 to ensure its stability and correct position. Then, the doctor will perform local anesthesia, and then accurately position the treatment area through image guidance technology, attach the silicone water sac body 3 to the target area. After confirming that the position is accurate, ultrasonic energy will be released in the silicone water sac body 3 through the probe, and energy will be transmitted to the target tissue area to form a high-temperature area for treatment. When replacing the silicone water sac body 3, the pre-fixing mechanism can fix the silicone water sac body 3 below the connecting block 2, reducing the inconvenience of the staff holding the silicone water sac body 3 with one hand while fixing the bolts.

[0034] Referring toFigure 2 and Figure 3 The pre - fixing mechanism includes connecting frames 8 fixedly connected to both sides of the bracket 1. On both sides inside the connecting block 2, there are sliding - connected special - shaped blocks two 12. On both sides at the bottom of the connecting frame 8, there are sliding holes 13. At the bottom of each special - shaped block two 12, there is fixedly connected a clamping block 14. The clamping block 14 is set in an L - shape. On both sides of the connecting block 2, there are fixedly connected side plates 15. On both sides at the top of the side plates 15, there are clamping grooves 16. The shape of the clamping groove 16 is adapted to the shape of the clamping block 14.

[0035] Among them, at the top of the clamping block 14, there is fixedly connected a friction pad 17. The top of the friction pad 17 abuts against the inner wall of the clamping groove 16.

[0036] In addition, a vertical rod 9 is slidably connected to the top of the connecting frame 8. At the top of the vertical rod 9, there is fixedly connected a driving head 10. The bottom end of the vertical rod 9 penetrates through the connecting frame 8 and is fixedly connected to a special - shaped block one 11. Both sides of the special - shaped block one 11 abut against the special - shaped blocks two 12. The contact surface between the special - shaped block one 11 and the special - shaped block two 12 is set as an inclined surface.

[0037] When fixing the silicone water - filled bag body 3, first press the driving head 10 to move downward. The driving head 10 drives the vertical rod 9 downward. The vertical rod 9 drives the special - shaped block one 11 downward. And when the special - shaped block one 11 moves downward, it will abut against the two special - shaped blocks two 12 on both sides. Due to the contact surface between the special - shaped block one 11 and the special - shaped block two being set as an inclined surface, the two special - shaped blocks two 12 move toward both sides. The movement of the special - shaped block two 12 drives the clamping blocks 14 at the bottom to move away from each other. At this time, place the connecting block 2 and the silicone water - filled bag body 3 under the bracket 1, so that the clamping blocks 14 enter the clamping grooves 16. Then pull the driving head 10 upward, so that the clamping blocks 14 are clamped and fixed with the clamping grooves 16, thus completing the pre - fixing of the silicone water - filled bag body 3. This makes it no longer necessary for the staff to hold the silicone water - filled bag body 3 with one hand and perform the complex operation of bolt - fixing with the other hand when replacing. When the clamping blocks 14 are clamped with the clamping grooves 16, since the friction pad 17 is made of rubber, it can increase the friction between the clamping blocks 14 and the clamping grooves 16, further improving the stability between the clamping blocks 14 and the clamping grooves 16.

[0038] Refer to Figures 2 to 4 On both sides of the special - shaped block one 11, there are fixedly connected dovetail blocks 21. On the mutually - approaching surfaces of the two special - shaped blocks two 12, there are dovetail grooves 22. The shape of the dovetail block 21 is adapted to the shape of the dovetail groove 22, and the dovetail block 21 is slidably connected to the dovetail groove 22.

[0039] When pulling the driving head 10 upward, the dovetail block 21 is slidably connected to the dovetail groove 22. Under the sliding action of the dovetail block 21 and the dovetail groove 22, the special - shaped block one 11 moves upward to drive the two special - shaped blocks two 12 to approach each other, so that the clamping blocks 14 and the clamping grooves 16 are firmly clamped.

[0040] Reference Figures 2 to 4 On both inner walls of the connecting frame 8, telescopic rods 18 are fixedly connected. One ends of the two telescopic rods 18 close to each other are fixedly connected to the second special-shaped block 12, and a spring 19 is sleeved on the outer surface of the telescopic rod 18.

[0041] When the driving head 10 is pressed, the two second special-shaped blocks 12 move away from each other and compress the spring 19, causing the spring 19 to generate elastic potential energy. When the engaging block 14 enters the engaging groove 16, no pressure is applied to the driving head 10 anymore. At this time, the elastic potential energy of the spring 19 is released, causing the two second special-shaped blocks 12 to move closer to each other, thereby driving the two engaging blocks 14 to engage with the engaging groove 16.

[0042] Reference Figures 2 to 4 One ends of the two second special-shaped blocks 12 away from each other are fixedly connected with guide posts 20. One ends of the two guide posts 20 away from each other penetrate through the connecting frame 8, and the guide posts 20 are slidably connected with the connecting frame 8.

[0043] When the two second special-shaped blocks 12 are in a special shape, the guide posts 20 provide a guiding effect for the second special-shaped blocks 12, so that the two second special-shaped blocks 12 maintain the correct movement track when moving.

[0044] Working principle: To fix the silicone water sac body 3 on the bracket 1 to ensure its stability and correct position, then the doctor will perform local anesthesia, and then accurately position the treatment area through image guidance technology. The silicone water sac body 3 is attached to the target area. After confirming that the position is accurate, ultrasonic energy will be released through the probe in the silicone water sac body 3. By transmitting energy to the target tissue area, a high-temperature area is formed for treatment. When installing the silicone water sac, press the driving head 10 to move downward. The driving head 10 drives the vertical rod 9 downward, and the vertical rod 9 drives the first special-shaped block 11 downward. And the downward movement of the first special-shaped block 11 will contact the two second special-shaped blocks 12. Since the contact surface between the first special-shaped block 11 and the second special-shaped block is set as an inclined surface, the two second special-shaped blocks 12 move to both sides. The movement of the second special-shaped block 12 drives the engaging blocks 14 at the bottom to move away from each other. At this time, place the connecting block 2 and the silicone water sac body 3 under the bracket 1, so that the engaging blocks 14 enter the engaging grooves 16, and then pull the driving head 10 upward, so that the two engaging blocks 14 move closer to each other, so that the engaging blocks 14 are engaged and fixed with the engaging grooves 16, thereby completing the pre-fixation of the silicone water sac body 3.
