Description

Technical Field

[0001] This invention relates to the field of medical devices, and more specifically, to a track fixator for knee joint ultrasound examination. Background Technology

[0002] Knee ultrasound examination is a commonly used medical imaging diagnostic method. It is mainly based on considerations such as improving the accuracy of the examination, reducing the impact of patient movement on image quality, and improving patient comfort. With the continuous improvement of ultrasound instruments and the advancement of imaging technology, high-frequency ultrasound plays an increasingly important role in the diagnosis of superficial soft tissue diseases. In particular, in recent years, high-resolution musculoskeletal ultrasound has been widely used in the diagnosis of knee joint diseases and has become an important imaging examination method.

[0003] During an ultrasound examination of the knee joint, the patient needs to cooperate with the examiner to adjust to different body positions so that the ultrasound probe can examine the degree of damage to different ligaments. However, this can be difficult for patients, as it is not easy to keep the knee joint stable at a fixed angle. Furthermore, some patients with knee injuries may find it even more difficult to achieve the ideal examination position due to pain or passivity, leading to a decrease in ultrasound image quality and thus affecting the accuracy of the diagnosis. Summary of the Invention

[0004] In view of the problems existing in the prior art, such as patients not being able to stably suspend their knee joint at a fixed angle, and some patients with knee injuries having difficulty achieving the ideal examination position due to pain or passivity, which leads to a decrease in ultrasound image quality and thus affects the accuracy of diagnosis, the purpose of this invention is to provide a track fixator for knee joint ultrasound examination.

[0016] Compared with the prior art, the technical solution provided by this invention has at least the following beneficial effects:

[0017] In the above scheme, by setting up a connecting membrane and a second gear, when the patient needs to adjust the patient's body position during an ultrasound examination of the knee joint, firstly, the restriction on the rotating shaft is released, and the knob is turned. The knob drives the rotating shaft and the second gear to rotate. The second gear drives the first gear and the rotating rod to rotate. The rotating rod drives the first adjusting plate to rotate, adjusting the angle of the first adjusting plate. When the first adjusting plate is adjusted to a position suitable for the patient's knee joint ultrasound examination, the rotating shaft is restricted by the limiting component to prevent the rotating shaft from rotating arbitrarily and affecting the ultrasound examination of the patient's knee joint. The first arc-shaped sponge block and the second arc-shaped sponge block can provide comfort for the patient during the knee joint ultrasound examination.

[0018] With a screw and threaded hole, when it is necessary to fix the patient's position, the patient's leg is passed through the middle of the device, so that the patient's knee joint is placed between the second support plate and the second adjustment plate. Then, the screw block is turned, which drives the screw to rotate in the first rectangular block and rotates the screw into the threaded hole on the second rectangular block, so that the patient's position is in contact with the first support plate, the first adjustment plate, the second support plate, and the second adjustment plate, thus fixing the patient's position and facilitating ultrasound examination of the knee joint of patients in different positions.

[0019] With the clamping plates and rubber pads in place, when it is necessary to clamp and fix the ultrasonic probe, place the ultrasonic probe on the top of the fixing plate, and then turn the screw. The screw drives the bidirectional threaded rod to rotate, and the bidirectional threaded rod drives the two clamping plates and rubber pads to move closer to each other along the length of the limiting rod, thus clamping and fixing the ultrasonic probe, which makes it easier for the ultrasonic probe to perform ultrasound examinations on the patient's body position.

[0020] Equipped with a motor and fan blades, when heat dissipation is needed for the patient's body position, the motor is activated, driving the fan blades to rotate. Through the rotation of the fan blades, air is forced through the rectangular frame into the first arc-shaped sponge block and then discharged through the first arc-shaped sponge block, thus dissipating heat for the patient's body position. The hot air can also be expelled through the heat dissipation holes. Attached Figure Description

[0044] like Figures 1 to 14As shown, this embodiment of the invention provides a track fixation device for knee joint ultrasound examination, including a first support plate 101 and a second support plate 102. A first adjusting plate 103 and a second adjusting plate 104 are rotatably connected to one side of the first support plate 101 and the second support plate 102, respectively. A first arc-shaped sponge block 105 is fixedly connected to the side of the first support plate 101 and the first adjusting plate 103 near the side of the first support plate 101 and the first adjusting plate 103. A second arc-shaped sponge block 106 is fixedly connected to the side of the second support plate 102 and the second adjusting plate 104 near the side of the first support plate 101 and the first adjusting plate 103. A rotating rod 107 is rotatably connected to the middle of the first support plate 101, and the front end of the rotating rod 107 rotatably passes through... The first support plate 101 has a first adjusting plate 103 fixedly connected to the outer surface of the rotating rod 107. An L-shaped plate 108 is fixedly connected to the front end of the first support plate 101. One end of the rotating rod 107 is rotatably connected to the L-shaped plate 108. A first gear 109 is fixedly connected to the outer surface of the rotating rod 107. A rotating shaft 110 is rotatably connected to the front end of the first support plate 101. The rotating shaft 110 rotatably passes through the L-shaped plate 108. A knob 111 is fixedly connected to the front end of the rotating shaft 110. A second gear 112 is fixedly connected to the outer surface of the rotating shaft 110. The second gear 112 meshes with the first gear 109. A limiting component for limiting the rotating shaft 110 is provided on the L-shaped plate 108.

[0045] When a patient needs to adjust their position during an ultrasound examination of their knee joint, the knob 111 is turned. The knob 111 drives the rotating shaft 110 and the second gear 112 to rotate. The second gear 112 drives the first gear 109 and the rotating rod 107 to rotate. The rotating rod 107 drives the first adjusting plate 103 to rotate, thus adjusting the angle of the first adjusting plate 103. When the first adjusting plate 103 is adjusted to a position suitable for the patient's knee joint ultrasound examination, the rotating shaft 110 is restricted by the limiting component to prevent it from rotating arbitrarily and affecting the ultrasound examination of the patient's knee joint. The first arc-shaped sponge block 105 and the second arc-shaped sponge block 106 can provide comfort for the patient during the knee joint ultrasound examination.

[0046] like Figure 5As shown, the limiting component includes a rectangular sleeve 201, which is fixedly connected to the front end of the L-shaped plate 108. A sliding block 202 is slidably connected to the inner wall of the rectangular sleeve 201. A handle 203 is fixedly connected to the top of the sliding block 202 and slides through the upper end of the rectangular sleeve 201. A first spring 204 is fixedly connected between the inner wall of the rectangular sleeve 201 and the sliding block 202. A connecting block 205 is fixedly connected to one side of the sliding block 202 and slides through one end of the rectangular sleeve 201. A plug rod 206 is fixedly connected to the rear end of the connecting block 205 and slides through the L-shaped plate 108. A circular plate 207 is fixedly connected to the outer surface of the rotating shaft 110. The circular plate 207 has multiple insertion holes 208 that cooperate with the plug rod 206.

[0047] When it is necessary to restrict the rotating shaft 110, pull the handle 203. The handle 203 drives the sliding block 202 to slide within the rectangular sleeve 201. The first spring 204 is compressed. The sliding block 202 drives the connecting block 205 to slide. The connecting block 205 drives the insertion rod 206 to leave the insertion hole 208 on the circular plate 207. Then, turn the knob 111. The knob 111 drives the rotating shaft 110 to rotate. The rotating shaft 110 drives the circular plate 207 and the second gear 112 to rotate, adjusting the angle of the first adjusting plate 103. When the first adjusting plate 103 is adjusted to a position suitable for ultrasound examination of the patient's knee joint, release the handle 203. The first spring 204 rebounds. The sliding block 202 drives the connecting block 205 and the insertion rod 206, so that the insertion rod 206 is inserted into the insertion hole 208 on the circular plate 207 to restrict the rotating shaft 110 and prevent the rotating shaft 110 from rotating arbitrarily.

[0048] like Figure 6 As shown, the second support plate 102 and the second adjustment plate 104 are symmetrically fixedly connected with connecting membranes 209 at their ends near the first support plate 101 and the first adjustment plate 103. The connecting membranes 209 are fixedly connected to the first support plate 101 and the first adjustment plate 103 at their ends near the first arc-shaped sponge block 105. The first support plate 101 and the first adjustment plate 103 are symmetrically fixedly connected with first rectangular blocks 210 at their ends. The middle of each of the four first rectangular blocks 210 is threaded with a screw 211. A screw block 212 is fixedly connected to one side of each screw 211. The second support plate 102 and the second adjustment plate 104 are symmetrically fixedly connected with second rectangular blocks 213 at their ends. Each of the four second rectangular blocks 213 has a threaded hole 214 that mates with the four screws 211.

[0049] When it is necessary to fix the patient's position, the patient's legs are passed through the middle of the device, so that the patient's knee joint is placed between the second support plate 102 and the second adjustment plate 104. Then, the screw block 212 is turned, which drives the screw 211 to rotate within the first rectangular block 210, rotating the screw 211 into the threaded hole 214 on the second rectangular block 213. This makes the patient's position contact the first support plate 101, the first adjustment plate 103, the second support plate 102, and the second adjustment plate 104, thus fixing the patient's position. This facilitates ultrasound examination of the knee joints of patients in different positions. The connecting membrane 209 can connect the first support plate 101, the second support plate 102, the first adjustment plate 103, and the second adjustment plate 104, and can also restrict and protect the patient's position.

[0050] like Figure 7 As shown, the second support plate 102 and the second adjustment plate 104 are fixedly connected to the same elastic strip 215 at the ends away from the connecting membrane 209. An ultrasonic track 216 is provided on the elastic strip 215, and a clamping component is provided on the elastic strip 215.

[0051] By incorporating the elastic strip 215 and the ultrasonic track 216, the elastic strip 215 and the ultrasonic track 216 facilitate the guidance of the clamping component, making the clamping component more stable during movement. The ultrasonic track 216 also makes it easier for staff to perform simple operations.

[0052] like Figure 8 As shown, the clamping assembly includes a fixing plate 217, which is slidably connected to an elastic strip 215. Positioning plates 218 are symmetrically fixed to the top of the fixing plate 217. A bidirectional threaded rod 219 is threaded between the two positioning plates 218. One end of the bidirectional threaded rod 219 rotatably passes through one of the positioning plates 218. A rotating block 220 is fixedly connected to one end of the bidirectional threaded rod 219. Two clamping plates 221 are threadedly connected to the bidirectional threaded rod 219. Rubber pads 222 are fixedly connected to the sides of the two clamping plates 221 that are close to each other. A limiting rod 223 is fixedly connected between the two positioning plates 218. Both clamping plates 221 slide through the limiting rod 223.

[0053] When it is necessary to clamp and fix the ultrasonic probe, place the ultrasonic probe on the top of the fixing plate 217, and then turn the screw block 220. The screw block 220 drives the bidirectional threaded rod 219 to rotate. The bidirectional threaded rod 219 drives the two clamping plates 221 and the rubber pad 222 to move closer to each other along the length of the limiting rod 223 to clamp and fix the ultrasonic probe, so that the ultrasonic probe can perform ultrasound examination on the patient's body position.

[0054] like Figure 8 and Figure 9 As shown, a connecting plate 224 is fixedly connected to the bottom end of the fixed plate 217. A sliding rod 225 is slidably connected to the middle of the connecting plate 224. A pull block 226 is fixedly connected to the front end of the sliding rod 225. A circular plate 227 is fixedly connected to the rear end of the sliding rod 225. A second spring 228 is fixedly connected between the front end of the circular plate 227 and the connecting plate 224. The second spring 228 is sleeved on the outside of the sliding rod 225. A pin 229 is fixedly connected to the rear end of the circular plate 227. A plurality of slots 230 that cooperate with the pins 229 are provided at the front end of the elastic strip 215.

[0055] When it is necessary to fix the clamping assembly, pull block 226 is pulled, which drives slide rod 225 to slide on connecting plate 224. Slide rod 225 drives circular plate 227 to slide, and second spring 228 is compressed. Circular plate 227 drives pin 229 to leave the slot 230 on elastic strip 215. Then, the clamping assembly is slid to slide the ultrasound detection head to the position where ultrasound examination of the patient is required. Pull block 226 is released, second spring 228 rebounds, and circular plate 227 drives pin 229 to insert into slot 230 on elastic strip 215, thus fixing the clamping assembly and facilitating ultrasound examination of the patient's position.

[0056] like Figure 10 and Figure 11 As shown, a rectangular opening 231 is provided at the lower end of the first support plate 101 and the left end of the first adjusting plate 103. A rectangular frame 232 is provided on the inner wall of the rectangular opening 231 at the lower end of the first support plate 101. A first filter screen 233 is slidably connected to the inner wall of the rectangular frame 232. An installation plate 234 is fixedly connected to the inner wall of the rectangular frame 232. A motor 235 is provided at the top of the installation plate 234. A fan blade 236 is fixedly connected to the output end of the motor 235. A second filter screen 237 is fixedly connected to the inner wall of the rectangular frame 232. The second filter screen 237 is located at the lower end of the installation plate 234. Multiple heat dissipation holes 249 are provided on the two connecting membranes 209.

[0057] When it is necessary to cool the patient's body position, the motor 235 is started. The motor 235 drives the fan blade 236 to rotate. Through the rotation of the fan blade 236, the gas enters the first arc-shaped sponge block 105 through the rectangular frame 232 and is discharged through the first arc-shaped sponge block 105 to cool the patient's body position. The hot air can be discharged through the heat dissipation hole 249.

[0058] like Figure 12 and Figure 13As shown, a rectangular shell 238 is fixedly connected to the front end of the rectangular frame 232. A connecting rod 239 is rotatably connected to the inner wall of the rectangular shell 238. A worm gear 240 is fixedly connected to the outer surface of the connecting rod 239. A worm 241 is rotatably connected to the inner wall of the rectangular shell 238. The worm 241 and the worm gear 240 cooperate with each other. The worm 241 rotatably passes through the lower end of the rectangular shell 238. A rotating block 242 is fixedly connected to the bottom end of the worm 241. A third gear 243 is fixedly connected to the outer surface of the connecting rod 239. The inner wall of the rectangular shell 238... Two rack plates 244 are symmetrically slidably connected at the top and bottom. The two rack plates 244 slide through the two ends of the rectangular shell 238 respectively. Both rack plates 244 mesh with the third gear 243. A connecting rod 245 is fixedly connected to the side of the two rack plates 244 that is far apart from each other. A plug block 246 is fixedly connected to the side of the two connecting rods 245 that is close to each other. Two limiting plates 247 are symmetrically fixedly connected to the first support plate 101 and the first adjusting plate 103 respectively. The limiting plates 247 are provided with a socket 248 that cooperates with the plug block 246.

[0059] When it is necessary to install and fix the rectangular frame 232, insert the rectangular frame 232 into the rectangular opening 231, and then turn the rotating block 242. The rotating block 242 drives the worm gear 241 to rotate, and the worm gear 241 drives the worm wheel 240 and the connecting rod 239 to rotate. The rotation of the connecting rod 239 drives the third gear 243, and the third gear 243 drives the two rack plates 244 to move in the same direction within the rectangular shell 238. The two rack plates 244 respectively drive the connecting rod 245 to move inward. The two connecting rods 245 respectively drive the insert block 246 to be inserted into the corresponding insertion opening 248 on the limiting plate 247, thereby installing and fixing the rectangular frame 232, which facilitates heat dissipation for different patient positions.

[0060] like Figure 7 As shown, a T-shaped slider 250 is slidably connected to the inner wall of the ultrasonic track 216, and the bottom end of the fixing plate 217 is fixedly connected to the T-shaped slider 250.

[0061] By providing a T-shaped slider 250, when the fixed plate 217 slides, it can drive the T-shaped slider 250 to slide within the ultrasonic track 216 on the elastic strip 215. Through the cooperation between the T-shaped slider 250 and the ultrasonic track 216, the clamping component can be limited, making the ultrasonic detection head more stable during movement.

[0062] like Figure 14 As shown, a long plate 251 is fixedly connected to the right end of the second adjustment plate 104, and coordinate scale 252 is provided on the long plate 251.

[0063] The long plate 251 allows staff unfamiliar with knee ultrasound operation to perform precise operations based on coordinate scale 252 under the remote guidance of senior doctors, thereby improving diagnostic accuracy.

[0064] The working process of the technical solution of this invention is as follows:

[0065] In use, the patient's leg is passed through the middle of the device, with the patient's knee joint placed between the second support plate 102 and the second adjustment plate 104. Then, the screw block 212 is turned, which drives the screw 211 to rotate within the first rectangular block 210, rotating the screw 211 into the threaded hole 214 on the second rectangular block 213, so that the patient's body position contacts the first arc-shaped sponge block 105 and the second arc-shaped sponge block 106, thus fixing the patient's body position. The first support plate 101, the second support plate 102, the first adjustment plate 103, and the second adjustment plate 104 are connected by the connecting membrane 209, which can also restrict and protect the patient's body position.

[0066] Then, pull the handle 203. The handle 203 causes the sliding block 202 to slide within the rectangular sleeve 201, compressing the first spring 204. The sliding block 202 causes the connecting block 205 to slide, and the connecting block 205 causes the insertion rod 206 to leave the insertion hole 208 on the circular plate 207. Then, turn the knob 111. The knob 111 causes the rotating shaft 110 to rotate, which in turn causes the insertion hole 208 and the second gear 112 to rotate. The second gear 112 drives the first gear 109 and the rotating rod 107 to rotate, and the rotating rod 107 drives the first adjustment... When plate 103 rotates, the angle of the first adjusting plate 103 is adjusted. When the first adjusting plate 103 is adjusted to a position suitable for performing ultrasound examination on the patient's knee joint, the handle 203 is released, the first spring 204 rebounds, and the sliding block 202 drives the connecting block 205 and the insertion rod 206, so that the insertion rod 206 is inserted into the insertion hole 208 on the circular plate 207 to restrict the rotating shaft 110 and prevent the rotating shaft 110 from rotating arbitrarily. Staff who are not familiar with knee joint ultrasound operation can perform precise operation through the coordinate scale 252 to improve the accuracy of diagnosis.

[0067] Then, place the ultrasonic detection head on the top of the fixed plate 217, and turn the rotating block 220. The rotating block 220 drives the bidirectional threaded rod 219 to rotate. The bidirectional threaded rod 219 drives the two clamping plates 221 and the rubber pad 222 to move closer to each other along the length direction of the limiting rod 223 to clamp and fix the ultrasonic detection head. Then, pull the pull block 226. The pull block 226 drives the slide rod 225 to slide on the connecting plate 224. The slide rod 225 drives the circular plate 227 to slide. The second spring 228 is compressed. The circular plate 227 drives the pin 229 to leave the slot 230 on the elastic strip 215. Then, slide the fixed plate 217. The fixed plate 217 drives the T-shaped slider 250 to slide in the ultrasonic track 216 on the elastic strip 215.

[0068] During the sliding process of the fixed plate 217, when the ultrasonic detection head is slid to the position where an ultrasound examination of the patient is required, the pull block 226 is released, the second spring 228 rebounds, and the circular plate 227 drives the pin 229 to insert into the slot 230 on the elastic strip 215, thereby fixing the fixed plate 217 and facilitating the ultrasonic detection head to perform an ultrasound examination of the patient's position.

[0069] When the temperature is high and it is necessary to adjust the patient's position to dissipate heat, insert the rectangular frame 232 into the rectangular opening 231. Then, turn the rotating block 242. The rotating block 242 drives the worm gear 241 to rotate. The worm gear 241 drives the worm wheel 240 and the connecting rod 239 to rotate. The rotation of the connecting rod 239 drives the third gear 243. The third gear 243 drives the two rack plates 244 to move in the same direction within the rectangular shell 238. The two rack plates 244 respectively drive the connecting rod 245 to move inward. 45 drives the insert 246 to be inserted into the corresponding socket 248 on the limiting plate 247 to install and fix the rectangular frame 232. Then, the motor 235 is started, and the motor 235 drives the fan blade 236 to rotate. Through the rotation of the fan blade 236, the gas enters the first arc-shaped sponge block 105 through the rectangular frame 232 and is discharged through the first arc-shaped sponge block 105 to dissipate heat from the patient's body position. The hot air can be discharged through the heat dissipation hole 249 to facilitate heat dissipation for different patient positions.
