Description

Technical Field

[0001] This invention relates to the field of cardiothoracic surgery technology, and in particular to a cardiothoracic surgical nursing thoracic cavity tube fixation stent. Background Technology

[0002] Thoracic surgery is a medical specialty that focuses on the study of organs within the thoracic cavity. When performing closed thoracic drainage, medical staff need to insert a drainage tube into the patient's thoracic cavity to drain gas or fluid from the pleural cavity, preventing external air and fluid from entering the thoracic cavity and ensuring the normal progress of the patient's treatment.

[0003] Traditionally, when inserting a drainage tube into a patient's chest wound, a medical bandage is used to secure the tube to prevent it from pulling on the wound and causing secondary injury, thus affecting the patient's treatment. However, in actual use, it has been found that one end of the drainage tube is connected to a drainage bottle, and the patient may move or shift, causing the drainage tube to shift and loosen, potentially tearing the wound and worsening it. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies where one end of the drainage tube is connected to a drainage bottle, and the patient's own movement causes the drainage tube to shift and shake, loosening its position and causing displacement, which can tear the patient's wound and, in severe cases, worsen the wound. The invention proposes a thoracic tube fixation stent for cardiothoracic surgery.

This prevents deviation and bending, which could lead to deformation and blockage of the drainage tube, affecting the drainage of gas and fluid from the patient's body. This improves the effectiveness of the drainage tube and the high efficiency and safety of the treatment.

[0017] The height of the drainage tube can be more easily and quickly fixed and adjusted, allowing for better adjustment of the drainage tube on the patient. It is less likely to be too high or too low, which could cause pulling damage to the patient's wound, ensuring more efficient and safer treatment for the patient and improving the overall effectiveness of the fixation device.

[0018] The angle of the drainage tube in the patient's chest cavity will be further improved and optimized, making it less prone to abnormal displacement and thus facilitating the drainage of gas and fluid. This also makes it easier for medical staff to perform treatment operations and improves the functionality and effectiveness of the entire fixation device. Attached Figure Description

[0029] Reference Figure 1 and Figure 2As shown, the present invention provides a technical solution: a cardiothoracic surgery nursing thoracic tube fixation bracket, including a base clamp 1, the base clamp 1 including a clamping block 101, a screw 102 threadedly connected to the surface of the clamping block 101, a stop plate 103 rotatably connected to one end of the screw 102 near the inner wall of the clamping block 101, a rotating device 2 provided on the surface of the base clamp 1, the rotating device 2 adjusting the horizontal angle of the drainage tube inserted into the patient's thoracic cavity, thereby better ensuring the proper use of the drainage tube, a lifting device 3 provided on one side of the rotating device 2, the lifting device 3 adjusting the height of the drainage tube installation, thereby making the position of the drainage tube more stable and reasonable, helping the fluid and gas inside the thoracic cavity to be better drained for treatment, an adjusting device 4 provided on one side of the lifting device 3, the components on the adjusting device 4 for installing the drainage tube, and further adjusting the vertical angle of the drainage tube, thereby assisting in a more stable and better placement of the drainage tube. This device is used for drainage of patients. When medical staff insert a drainage tube into the patient's chest cavity during closed chest drainage, the clamp 101 is secured to one side of the operating table, and the screw 102 is rotated so that the stop plate 103 on the screw 102 contacts and presses against the operating table to position the entire device. Then, the drainage tube is installed on the adjustment device 4, and the rotation device 2 is operated to change the horizontal angle of the drainage tube. The lifting device 3 is then operated to adjust the height of the drainage tube, and finally, the adjustment device is operated to change the vertical angle of the drainage tube. During closed chest drainage, the drainage tube can be used better. While ensuring the position of the drainage tube is fixed, the height and angle of the drainage tube are more suitable for the position of the drainage tube inserted into the patient's chest cavity, so that the drainage tube is less likely to pull on the patient's chest wound and cause secondary injury. This better protects the patient and improves the safety and functionality of the drainage tube.

[0030] Reference Figure 1-9As shown in this embodiment: the rotating device 2 includes a base plate 21, which is fixedly connected to the surface of the clamping block 101. A rotating ring 22 is fixedly connected to the surface of the base plate 21, and a rotating plate 23 is rotatably connected to the inner wall of the rotating ring 22. A slide rail 31 of the lifting device 3 is fixedly connected to the surface of the rotating plate 23. Several evenly distributed fixing grooves 24 are opened on the surface of the base plate 21. Two assembly blocks 25 are fixedly connected to the surface of the slide rail 31 near the surface of the base plate 21. A rotating shaft 26 is rotatably connected through the side of the two assembly blocks 25 that is close to each other. A fixed connection is made to the arc surface of the rotating shaft 26. A sliding frame 27 is connected to a fixed plate 28, which is slidably connected to the inner wall of the sliding frame 27. The fixed plate 28 is inserted into the inner wall of the fixed groove 24. A first spring 29 is fixedly connected to the inner wall of the sliding frame 27, and the other end of the first spring 29 is fixedly connected to the surface of the fixed plate 28. Mounting grooves 210 are respectively opened through both sides of the surface of the sliding frame 27. An assembly column 211 is provided on the inner wall of the mounting groove 210. The assembly column 211 is fixedly connected to the surface of the fixed plate 28. A combination rod 212 is fixedly connected to the surface of the rotating plate 23. A bearing 21 is fixedly connected to the arc surface of the combination rod 212. 3. The inner ring of bearing 213 is fixedly connected to the combined rod 212, and the outer ring of bearing 213 is fixedly connected to the surface of the base plate 21. When adjusting the horizontal angle of the drainage tube on the device, first rotate the rotating plate 23 so that the inner wall of the rotating ring 22 fixedly connected to the surface of the base plate 21 rotates. After the horizontal angle of the drainage tube is adjusted, rotate the rotating shaft 26 so that the combined block 25 on the slide rail 31 rotates, causing the sliding frame 27 to rotate accordingly until the fixing plate 28 on the inner wall of the sliding frame 27 is fixed to the fixing groove 24 on the surface of the base plate 21. Align the tube and then release the fixing plate 28. The fixing plate 28 will slide under the elastic force of the first spring 29, allowing it to slide on the inner wall of the sliding frame 27 until it is inserted into the fixing groove 24, thus fixing the position of the rotating plate 23. At this time, when the position of the drainage tube is limited and fixed, the horizontal angle can be better adjusted, keeping the angle of the drainage tube when inserted into the chest cavity stable and preventing deviation or bending, which could lead to deformation and blockage of the drainage tube, affecting the drainage of gas and fluid from the patient's body. This improves the effectiveness of the drainage tube and the high efficiency and safety of the treatment.

[0031] Reference Figure 1-9As shown in this embodiment: A lever 216 is fixedly connected to one side surface of the fixed plate 28. The surface of the lever 216 is provided with several anti-slip protrusions. By setting the lever 216, when the horizontal angle of the drainage tube is adjusted for the second time, the lever 216 on the fixed plate 28 can be pulled by finger, so that the fixed plate 28 can be disengaged from the fixing groove 24 on the base plate 21 more quickly. It is not easy for the fixed plate 28 to slip off the fixing groove 24, which would affect the disengagement effect. This makes it easier to fix the fixed plate 28 to the fixing groove 24 for the second time, improving the convenience and functionality of the fixed plate 28. Fixing plates 215 are fixedly connected to both sides of the surface of the rotating shaft 26. Torsion springs 214 are sleeved on both sides of the surface of the rotating shaft 26. The two ends of the torsion springs 214 are fixedly connected to the fixing plates 215 and the combination block 25, respectively. By setting the torsion springs 214 and the fixing plates 215, the rotation of the rotating plate 23 affects the drainage tube. After adjusting the horizontal angle, release the sliding frame 27. The sliding frame 27 will rotate under the torsional force of the torsion spring 214, so that the fixing plate 28 on the inner wall of the sliding frame 27 will align more quickly with the fixing groove 24 on the base plate 21. This will allow for a faster and more accurate adjustment and fixation of the horizontal angle of the drainage tube. The surface of the slide rail 31 is fixedly connected to a contact plate 217 on one side of the assembly block 25. The surface of the contact plate 217 abuts against the sliding frame 27. Through the setting of the contact plate 217, the rotating shaft 26 will rotate under the torsional force of the torsion spring 214. When the sliding frame 27 rotates to a perpendicular angle with the base plate 21, the contact plate 217 fixedly connected to the slide rail 31 will contact and press against the sliding frame 27, thereby stabilizing the position of the sliding frame 27. At this time, the fixing plate 28 will be inserted into the fixing groove 24 more quickly under the action of the first spring 29, improving the ease of use of the rotating device 2.

[0032] Reference Figure 1-9As shown in this embodiment: a groove 32 is formed through one side surface of the slide rail 31. Two assembly rods 33 are slidably connected to the inner wall of the groove 32. Nuts 39 are threaded onto the arc surfaces of the two assembly rods 33. A support rod 34 is fixedly connected to one end of the two assembly rods 33 at the position of the inner wall of the slide rail 31. A combination plate 37 is fixedly connected to the inner wall of the slide rail 31. Second springs 38 are fixedly connected to both sides of the surface of the combination plate 37. The other end of the second springs 38 is fixedly connected to the support rod 34. A connecting shaft 35 is fixedly connected to one end of the support rod 34. A connecting frame 36 is rotatably connected to the arc surface of the connecting shaft 35. An electric telescopic rod 313 is fixedly connected to the surface of the connecting frame 36. A positioning frame 314 is fixedly connected to the output end of the electric telescopic rod 313. Several evenly distributed slots 315 are formed on the inner wall of the positioning frame 314. A positioning post 316 is fixedly connected to one end of the support rod 34. When adjusting the height of the drainage tube on the device, medical staff will press it by hand. The two support rods 34 on the slide rail 31 slide on the inner wall of the slide rail 31, and the mounting rods 33 on the two support rods 34 slide closer to or further away from each other on the inner wall of the slide rail 31. At this time, the connecting shaft 35 on the support rod 34 rotates on the connecting frame 36, thereby causing the drainage tube on the adjusting device 4 to rise and fall in height. After the adjustment is completed, the nut 39 is threaded onto the arc surface on the mounting rod 33. At the same time, the electric telescopic rod 313 on the connecting frame 36 is activated, causing the electric telescopic rod 313 to drive the positioning frame 314 on its output end to move. The positioning pins 316 on the two support rods 34 will engage with the slots 315 on the inner wall of the connecting frame 36, thereby stabilizing the entire device. At this time, the height of the drainage tube can be fixed more conveniently and quickly, which can better adjust the drainage tube on the patient and prevent it from being too high or too low, which would cause pulling damage to the patient's wound. This ensures more efficient and safe treatment for the patient and improves the overall effectiveness of the fixation device.

[0033] Reference Figure 1-9As shown in this embodiment: a plurality of evenly distributed positioning grooves 310 are formed on one side surface of the slide rail 31; positioning plates 311 are fitted onto the arc surfaces of the two mounting rods 33; the positioning plates 311 are inserted into the inner walls of the positioning grooves 310; a third gear 318 is fixedly connected to one end of the connecting shaft 35; the third gears 318 on the two connecting shafts 35 mesh with each other; when the sliding two support rods 34 change the position and height of the drain pipe on the device, the connecting shafts 35 on the two support rods 34 move in opposite directions. When the rod rotates, the third gears 318 on the two connecting shafts 35 will mesh and rotate, making the rotation of the support rod 34 more stable and precise. The positioning plate 311 is placed on the arc surface of the assembly rod 33, and then the positioning plate 311 is inserted into the positioning groove 310 on the surface of the slide rail 31. The nut 39 is then threaded onto the assembly rod 33. At this time, the support rod 34 will be more firmly placed in the inner wall of the slide rail 31, improving the positioning effect of the bolt 412 and making the position of the drainage tube more suitable for treatment.

[0034] Reference Figure 1-9 As shown in this embodiment: an anti-slip plate 312 is fixedly connected to the surface of the support rod 34. The surface of the anti-slip plate 312 is provided with several anti-slip stripes. A reinforcing sleeve 317 is fixedly connected to the arc surface of the positioning column 316. The reinforcing sleeve 317 is a rubber sleeve. When the height of the drainage tube on the device is adjusted, the support rod 34 is pressed, and the support rod 34 slides on the slide rail 31. The fingers can more stably contact and squeeze the support rod 34, and it is not easy to slip or deviate. This makes the height adjustment more efficient. After the adjustment is completed, the slot 315 on the inner wall of the positioning frame 314 will be engaged with the positioning column 316. The friction of the engagement can be further improved by the setting of the reinforcing sleeve 317, which makes the height position of the drainage tube more stable and less prone to shaking or deviating. This improves the use effect and practicality of the lifting device 3.

[0035] Reference Figure 1-9As shown, in this embodiment: the adjusting device 4 includes a mounting frame 41, which is fixedly connected to the surface of the connecting frame 36. A first gear 42 is rotatably connected to the inner wall of the mounting frame 41. A rotating handle 47 is rotatably connected to one end of the first gear 42. A chuck 48 is fixedly connected to the arc surface of the rotating handle 47. A fixing block 49 is fixedly connected to the surface of the mounting frame 41. A sliding rod 410 is slidably connected through the surface of the fixing block 49. An insert block 411 is fixedly connected to one end of the sliding rod 410. The insert block 411 is inserted into the inner wall of the chuck 48. A bolt 412 is inserted through the surface of the fixing block 49. The bolt 412 is threadedly connected to the surface of the sliding rod 410. Second gears 43 are respectively provided on both sides of the surface of the mounting frame 41. Gear 42 meshes with second gear 43. A connecting band 44 is provided on the inner wall of second gear 43. Adjusting plates 45 are rotatably connected to both sides of one end surface of mounting frame 41. A tube mounting frame 46 is fixedly connected to the surface of adjusting plate 45. The other end of the connecting band 44 is fixedly connected to the tube mounting frame 46. Several evenly distributed mounting shafts 414 are fixedly connected to one side surface of tube mounting frame 46. Flipping plates 415 are rotatably connected to the arc surfaces of the mounting shafts 414. An assembly shaft 416 is rotatably connected to one side of the flipping plate 415. A positioning disc 417 is rotatably connected to the arc surface of the assembly shaft 416. A connecting rod 418 is rotatably connected to the surface of the flipping plate 415. A fourth spring 419 is fixedly connected to the surface of tube mounting frame 46. The other end of the spring 419 is fixedly connected to the flip plate 415. When the drainage tube is installed on the device component, the drainage tube is first clamped in the inner wall of the tube mounting frame 46, and then the connecting rod 418 is released. At this time, the flip plate 415 will rotate on the arc surface of the mounting shaft 414 on one side of the tube mounting frame 46 under the pulling force of the fourth spring 419. Under the combined effect of the connecting rod 418, several mounting shafts 416 on the tube mounting frame 46 will be displaced and move closer to the drainage tube on the inner wall of the tube mounting frame 46 until the positioning plate 417 on the mounting shaft 416 is clamped on the surface of the drainage tube. Then, the rotating handle 47 on the first gear 42 is rotated. The rotation of the first gear 42 will drive the second gears 43 on both sides to rotate simultaneously, thereby causing the two connecting shafts on both sides to rotate. The band 44 will retract or extend, causing the tube mounting frame 46 to rotate relative to the position of the adjusting plate 45, thereby better aligning the drainage tube with the patient's chest cavity. At this time, the sliding rod 410 will slide on the surface of the fixing block 49 until one end of the sliding rod 410 is fixedly connected to the insert block 411 and inserted into the surface of the chuck 48. Then, the bolt 412 on the fixing block 49 is threaded onto the sliding rod 410, stabilizing the position of the first gear 42 and fixing the angle of the tube mounting frame 46. At this time, the setting angle of the drainage tube on the patient's chest cavity will be further improved and reasonable, and it will be less prone to abnormal displacement, thereby better draining gas and fluid, making it more convenient for medical staff to perform treatment operations, and improving the functionality and effectiveness of the entire fixation device.

[0036] Reference Figure 1-9 As shown in this embodiment: a third spring 413 is sleeved on the arc surface of the sliding rod 410. The two ends of the third spring 413 are fixedly connected to the insert block 411 and the fixing block 49, respectively. With the setting of the third spring 413, after the adjustment of the rotating handle 47 and the rotation of the first gear 42 to adjust the vertical angle of the drain pipe on the tube frame 46, the sliding rod 410 will be positioned under the elastic force of the third spring 413, so that the sliding rod 410 slides on the surface of the fixing block 49. This allows the insert block 411, which is fixedly connected to one end of the sliding rod 410, to be inserted into the surface of the chuck 48 more quickly. It also makes it convenient for the bolt 412 to fix the position of the sliding rod 410, thus improving the convenience and efficiency of the device.

[0037] Working principle: When medical staff insert a drainage tube into the patient's chest cavity during closed chest drainage, they clamp block 101 onto one side of the operating table and rotate screw 102 so that the abutment plate 103 on screw 102 contacts and presses against the operating table to position the entire device. Then, the drainage tube is installed on the adjusting device 4. The drainage tube is installed on the adjusting device 4. Then, the rotating device 2 is operated to change the horizontal angle of the drainage tube. Next, the lifting device 3 is operated to adjust the height of the drainage tube. Finally, the adjusting device is operated to change the vertical angle of the drainage tube. During closed chest drainage, the drainage tube can be used better. While ensuring the position of the drainage tube is fixed, the height and angle of the drainage tube are more suitable for the position of the drainage tube inserted into the patient's chest cavity. This makes it less likely for the drainage tube to pull on the patient's chest wound and cause secondary damage, thus better protecting the patient and improving the safety and functionality of the drainage tube.Next, operate the rotating device 2 to change the horizontal angle of the drainage tube. Rotate the rotating plate 23, causing the inner wall of the rotating ring 22 fixedly connected to the bottom plate 21 to rotate. After the horizontal angle of the drainage tube is adjusted, rotate the rotating shaft 26, causing the assembly block 25 on the slide rail 31 to rotate, causing the sliding frame 27 to rotate accordingly until the fixing plate 28 on the inner wall of the sliding frame 27 is aligned with the fixing groove 24 on the surface of the bottom plate 21. Then release the fixing plate 28, which will slide under the elastic force of the first spring 29, allowing the fixing plate 28 to slide on the inner wall of the sliding frame 27 until... The fixing plate 28 is inserted into the fixing groove 24 to fix the position of the rotating plate 23. Then, the lifting device 3 is operated to adjust the height of the drainage tube. Medical staff will press the two support rods 34 on the slide rail 31 by hand. The two support rods 34 will slide on the inner wall of the slide rail 31, and the mounting rods 33 on the two support rods 34 will slide closer or further away from each other on the inner wall of the slide rail 31. At this time, the connecting shaft 35 on the support rod 34 will rotate on the connecting frame 36, thereby causing the drainage tube on the adjusting device 4 to rise and fall in height. After the adjustment is completed, the nut 39 is threaded onto the arc surface of the mounting rod 33, and the device is started. The electric telescopic rod 313 on the connecting frame 36 causes the positioning frame 314 on its output end to move. The positioning posts 316 on the two support rods 34 will engage with the slots 315 on the inner wall of the connecting frame 36. Finally, the rotating handle 47 on the first gear 42 is rotated. The rotation of the first gear 42 will drive the second gears 43 on both sides to rotate simultaneously, thereby causing the two connecting bands 44 on both sides to retract or extend. This causes the tube mounting frame 46 to rotate around the position of the adjusting plate 45, so that the drainage tube is better aligned with the patient's chest cavity. At this time, the sliding rod 410 will be on the surface of the fixing block 49. Slide the slide rod 410 until one end of the sliding rod 410 is fixedly connected to the insert block 411 and inserted into the surface of the chuck 48. Then, thread the bolt 412 on the fixing block 49 onto the sliding rod 410 to stabilize the position of the first gear 42, thereby fixing the vertical angle of the tube frame 46. At this time, the drainage tube can be used better during closed chest drainage. While ensuring the position of the drainage tube is fixed, the height and angle of the drainage tube assembly are more suitable for the position of the drainage tube inserted into the patient's chest cavity. This makes it less likely for the drainage tube to pull on the patient's chest wound and cause secondary damage, thus better protecting the patient and improving the safety and functionality of the drainage tube.
