Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a body positioner for intraspinal anesthesia. Background Art

[0002] Intrathecal anesthesia is the injection of local anesthetics into the subarachnoid space or epidural space in the spinal canal, which blocks the conduction of spinal nerves and eliminates the pain in the corresponding area, thereby achieving the anesthetic effect.

[0003] In the field of clinical anesthesia, spinal anesthesia is a commonly used anesthesia method. When implementing spinal anesthesia, the patient needs to cooperate in assuming a specific body position, usually a side-lying position, and curl up the legs to the chest to facilitate the anesthesiologist to perform the puncture operation. However, many patients are nervous, anxious, or lack surgical experience. This nervousness may cause the patient's body to become stiff, making it difficult for the patient to accurately assume a suitable body position in a short period of time to cooperate with the anesthesiologist's operation, thereby affecting the smooth progress of the anesthesia puncture. In addition, for obese patients, due to the particularity of their body structure, the action of curling up the legs may be more difficult or even impossible to complete. This requires the anesthesiologist to spend a lot of time and energy to adjust the patient's body position in actual work, and may even cause conflicts in doctor-patient communication due to improper body position, adding unnecessary workload. Therefore, the present invention provides a body position device for spinal anesthesia to meet the needs. Summary of the Invention

[0044] It should be noted that references in the specification to "one embodiment," "an embodiment," "exemplary embodiments," "some embodiments," etc. indicate that the described embodiments may include specific features, structures, or characteristics, but not necessarily every embodiment will include such specific features, structures, or characteristics. Furthermore, when specific features, structures, or characteristics are described in conjunction with an embodiment, it is within the knowledge of persons skilled in the relevant art to implement such features, structures, or characteristics in conjunction with other embodiments (whether or not explicitly described).

[0045] like Figures 1 to 17 As shown, an embodiment of the present invention provides a positioning device for intrathecal anesthesia, including a holding tube 1. The holding tube 1 is a metal cylinder, and the outer wall is covered with a rubber protective film of a certain thickness, so that the outer wall of the holding tube 1 becomes soft. When the patient holds the holding tube 1, it can not only improve the patient's comfort, but also give the patient psychological comfort to a certain extent, thereby reducing the patient's fear of surgery. A first sliding cavity 2 is provided in the holding tube 1. The first sliding cavity 2 is a cylindrical groove body. Two first sliding grooves 3 are provided on the outer wall of the holding tube. The first sliding groove 3 is a U-shaped groove body, and the two first sliding grooves are distributed in a circular array on the outer wall of the holding tube. The two first sliding grooves are both connected to the first sliding cavity. As shown Figure 7 and Figure 8 As shown, a second sliding groove 5 is provided on the outer wall of one end of the holding tube 1, and the second sliding groove 5 is a square groove body, and the second sliding groove 5 is connected to the first sliding cavity 2. A first avoidance groove 6 is provided on the outer wall of the holding tube 1 near one end of the second sliding groove 5, and the first avoidance groove 6 is composed of two parts, a square groove body and a triangular groove body, wherein the triangular groove body is located on the side of the first avoidance groove 6 close to the first sliding cavity 2 and is connected to the first sliding cavity 2. Two fixing columns 4 are fixedly connected to the inner wall of the holding tube 1 near the first avoidance groove 6, and the fixing columns 4 are plastic cylinders, and the two fixings are symmetrical about the central axis of the holding tube 1; an auxiliary component, the auxiliary component is used to assist the patient in placing in a fixed position, and the auxiliary component is connected to the holding tube 1.

[0046] By setting up auxiliary components, this application can not only assist medical staff in turning the patient over before anesthesia, and provide support for the device after the patient turns over, to prevent the patient from changing his body position due to accidental movement, which affects the anesthesiologist's operation, but also adapt to the length of the legs of different patients, and through adjustment, assist the patient to complete the action of curling up his legs towards the chest, quickly meeting the body position requirements of the anesthesiologist.

[0047] In this embodiment, if Figures 1 to 4 、 Figures 7 to 12As shown, the auxiliary assembly includes a first sliding post 16 slidably connected to the inner wall of the first sliding groove 3. The first sliding post 16 is composed of two parts: a metal cylinder and a metal circular plate. The outer wall profile of the metal cylinder portion of the first sliding post 16 is adapted to the inner wall profile of the first sliding groove 3, so the first sliding post 16 can slide on the inner wall of the first sliding groove 3. Since the first sliding groove 3 is a U-shaped groove body, when the first sliding post 16 slides into the two ends of the first sliding groove 3, the first sliding groove 3 can limit the first sliding post 16. The two first sliding columns 16 are fixedly connected to the same sliding circular plate 14 at one end away from the metal circular plate. The sliding circular plate 14 is a hollow metal circular plate, and the outer wall contour of the sliding circular plate 14 is adapted to the inner wall contour of the first sliding cavity 2, so the sliding circular plate 14 can slide in the first sliding cavity 2. The first sliding column 16 is rotatably connected to the first fixed cylinder 20 at one end away from the sliding circular plate 14. The first fixed cylinder 20 is a metal cylinder. A first rotating groove 21 is provided on the outer wall of the end of the first fixed cylinder 20 close to the first sliding column 16. The first rotating groove 21 is a cylindrical groove body with a "convex" cross-section, and the inner wall contour of the first rotating groove 21 is adapted to the outer wall contour of the metal circular plate part on the first sliding column 16, so the first fixed cylinder 20 can rotate on the outer wall of the first sliding column 16. The first fixed cylinder 20 is fixedly connected to a first curved plate 22 at one end away from the first sliding cylinder 16. The first curved plate 22 is composed of a square plastic plate and a curved plastic plate. The curved plastic plate portion of the first curved plate 22 can provide guidance when the patient turns over, while the square plastic plate portion of the first curved plate 22 can provide support for the device after the patient turns over. The first sliding cylinder 16 is rotatably connected to a pad 17 at one end near the first fixed cylinder 20. The pad 17 is made of rubber and has a second avoidance groove 19 on its outer wall. The second avoidance groove 19 is an arc-shaped groove. The second avoidance groove 19 cooperates with the elasticity of the pad 17 to adapt to the contour of the patient's arm, thereby improving the patient's comfort when the patient wraps his arm around the pad 17. A second rotating groove 18 is provided on the outer wall of one end of the pad 17 close to the first fixed cylinder 20. The second rotating groove 18 is a circular groove body, and the inner wall contour of the second rotating groove 18 is adapted to the outer wall contour of the first fixed cylinder 20. Therefore, the pad 17 can rotate on the outer wall of the first fixed cylinder 20, so that when the patient turns over, the arm can be kept on the second avoidance groove 19 provided on the pad 17. The above structural setting allows the patient to hold the holding tube 1 and let his arms hold the pad 17. This will improve the patient's comfort, relieve the patient's tension, and help the patient assume a suitable posture. It can also provide support for the patient after the patient turns over, to avoid the patient's posture change due to accidental movement, thereby affecting the anesthesiologist's operation.

[0048] In this embodiment, if Figures 4 to 10As shown, a first rotating cylinder 7 is fixedly connected to the inner wall of the first avoidance groove 6, and the first rotating cylinder 7 is a metal cylinder. A rotating connecting plate 11 is rotatably connected to the outer wall of the first rotating cylinder 7. The rotating connecting plate 11 is a square plastic plate with curved ends. Rotating circular holes 12 are symmetrically opened on the outer wall of the rotating connecting plate 11 near both ends. The rotating circular holes 12 are a groove body with a circular structure. The rotating circular hole 12 near the first avoidance groove 6 has an inner wall contour that is adapted to the outer wall contour of the first rotating cylinder 7, so the rotating connecting plate 11 can rotate on the outer wall of the first rotating cylinder 7. The end of the rotating connecting plate 11 away from the first avoidance groove 6 is rotatably connected to the turning pad 8. The turning pad 8 is in the shape of a mountain as a whole and is made of rubber. It consists of two side supports and a middle support. The height of the middle support is greater than the height of the two side supports, and a number of segmented grooves 9 distributed in a linear array are opened on the outer wall between the side supports and the middle support. The segmented grooves 9 facilitate the deformation of the turning pad 8 after being squeezed, adapting to the contour of the patient's thigh, providing more comfortable support for the patient, and assisting medical staff in turning the patient over. The turning pad 8 is disclosed in the prior art, so it will not be described in detail. The outer wall of the end of the rotating connecting plate 11 away from the turning pad 8 is fixedly connected to the second contact plate 13, which is a plastic plate with a trapezoidal structure. A fourth avoidance groove 10 is provided on the outer wall of the turning pad 8 near the rotating connecting plate 11, and a second rotating cylinder 47 is fixedly connected to the inner wall of the fourth avoidance groove 10. The fourth avoidance groove 10 is a square groove body. Since the inner wall contour of the fourth avoidance groove 10 is adapted to the outer wall contour of the rotating connecting plate 11 away from the second contact plate 13, the fourth avoidance groove 10 can provide an avoidance space when the rotating connecting plate 11 rotates, and the rotating circular hole 12 on the rotating connecting plate 11 near the turning pad 8 has an inner wall contour adapted to the outer wall contour of the second rotating cylinder 47, so the rotating connecting plate 11 can rotate along the outer wall of the second rotating cylinder 47. When adjusting the body position, the inclined surface of the second contact plate 13 will be affected. When the patient's thigh is turned over, the medical staff can move the turning pad 8 to rotate along the inner wall of the rotating circular hole 12 on the rotating connecting plate 11 close to the fourth avoidance groove 10, so that the turning pad 8 is kept parallel to the holding tube 1. The above structural setting can not only adapt to the contour of the patient's thigh and provide more comfortable support, but also facilitate medical staff to assist the patient in turning over; it can also lift the patient's thigh and adjust the leg curling angle in conjunction with subsequent operations; in addition, the device can be stored by moving the turning pad 8 to keep it parallel to the pillow.

[0049] In this embodiment, if Figures 4 to 6 and Figures 11 to 14As shown, a third rotating groove 15 is formed on the outer wall of the sliding circular plate 14 at one end near the second sliding groove 5. The third rotating groove 15 is a convex groove body. A first rotating circular plate 23 is rotatably connected to the inner wall of the third rotating groove 15. The first rotating circular plate 23 is a hollow metal circular plate, and the outer wall profile of the first rotating circular plate 23 matches the inner wall profile of the third rotating groove 15, so the first rotating circular plate 23 can rotate on the inner wall of the third rotating groove 15. Two cables 24 are fixedly connected to the outer wall of the first rotating circular plate 23 on the side near the second sliding groove 5. The cables 24 are made of metal and are symmetrical about the central axis of the first rotating circular plate 23. The cables 24 are known in the prior art and are not described in detail here. After the two ends of the two cables 24 away from the first rotating circular plate 23 pass around the outer walls of the two fixed columns 4 respectively, they are fixedly connected to the outer wall of the same fixed circular plate 25 close to the second sliding groove 5. The fixed circular plate 25 is a metal circular plate, and the outer wall contour of the fixed circular plate 25 is adapted to the inner wall contour of the sliding circular plate 14. The fixed circular plate 25 will pass through the inner wall of the sliding circular plate 14. When the sliding circular plate 14 slides along the inner wall of the first sliding cavity 2 in the direction away from the second sliding groove 5, the sliding circular plate 14 will pull the cable 24, and the cable 24 will pull the fixed circular plate 25 to move in the direction of the second sliding groove 5. A second sliding post 26 is fixedly connected to the middle of the outer wall of the fixed circular plate 25 near the second sliding groove 5. The second sliding post 26 is a metal cuboid, and the outer wall profile of the second sliding post 26 is adapted to the inner wall profile of the second sliding groove 5. When the fixed circular plate 25 moves toward the second sliding groove 5, the second sliding post 26 can slide along the inner wall of the second sliding groove 5 driven by the fixed circular plate 25. Figure 6As shown, the second sliding column 26 defines a second sliding cavity 31. The second sliding cavity 31 is a square chamber. A fourth rotation groove 32 is defined on the inner wall of the end of the second sliding cavity 31 near the fixed circular plate 25. The fourth rotation groove 32 is a circular groove with a convex cross-section. A rotation rod 44 is rotatably connected to the inner wall of the fourth rotation groove 32. The rotation rod 44 is a metal cylinder with threads on the outer wall near the middle. A rotation protrusion 45 is fixedly connected to the end near the fourth rotation groove 32. The rotation protrusion 45 is a metal protrusion with a convex cross-section. The outer wall profile of the rotation protrusion 45 matches the inner wall profile of the fourth rotation groove 32, allowing the rotation rod 44 to rotate on the inner wall of the fourth rotation groove 32. A rotation handle 46 is fixedly connected to the end of the rotation rod 44 away from the rotation protrusion 45. The rotation handle 46 is a metal cylinder with an anti-slip groove on the outer wall. Rotating the rotation handle 46 can drive the rotation rod 44 to rotate synchronously. A fifth rotating groove 33 is provided at the end of the second sliding cavity 31 away from the fourth rotating groove 32. The fifth rotating groove 33 is a circular groove body. Since the outer wall contour of the rotating rod 44 away from the rotating protrusion 45 is adapted to the inner wall contour of the fifth rotating groove 33, the rotating rod 44 can also rotate on the inner wall of the fifth rotating groove 33. The second sliding column 26 is symmetrically fixedly connected to the outer walls on both sides near the second rotating groove 18 with the third sliding column 28. The third sliding column 28 is composed of two parts: a metal cylinder and a metal circular plate. The metal circular plate is located at the end of the third sliding column 28 away from the second sliding column 26. The end of the third sliding column 28 away from the second sliding column 26 is rotatably connected to the second fixed cylinder 29. The second fixed cylinder 29 is a metal cylinder. A sixth rotating groove 48 is provided on the outer wall of the end of the second fixed cylinder 29 close to the third sliding column 28. The sixth rotating groove 48 is a groove body with a convex cross-section, and the inner wall contour of the sixth rotating groove 48 is adapted to the outer wall contour of the end of the third sliding column 28 away from the second sliding column 26, so the second fixed cylinder 29 can rotate on the outer wall of the third sliding column 28. A second curved plate 30 is fixedly connected to the outer wall of one end of the second fixed cylinder 29 away from the third sliding column 28. The second curved plate 30 is composed of two parts: a square plastic plate and a curved plastic plate. The curved plastic plate part on the second curved plate 30 can provide a guide when the patient turns over, and the square plastic plate part on the second curved plate 30 can cooperate with the first curved plate 22 to provide support for the device after the patient turns over. The above structural setting can slide the second sliding column 26 in the first sliding cavity 2 out by sliding the first sliding column 16, which facilitates the subsequent adjustment of the patient's position, and the device can be stored after use, thereby saving space.

[0050] In this embodiment, if Figure 5 、 Figures 14 to 17As shown, third sliding grooves 27 are symmetrically provided on both sides of the second sliding column 26. The third sliding grooves 27 are square grooves with curved ends. A sliding plate 40 is slidably connected to the inner wall of the third sliding groove 27. The sliding plate 40 is a square metal plate, and the outer wall profile of the sliding plate 40 is adapted to the inner wall profile of the third sliding groove 27. A first sliding cylinder 38 is fixedly connected to the outer wall of one end of the sliding plate 40. The first sliding cylinder 38 is a hollow metal cylinder with a square structure, and the inner wall profile of the first sliding cylinder 38 is adapted to the outer wall profile of the second sliding column 26, so the first sliding cylinder 38 can slide on the outer wall of the second sliding column 26, and the end of the sliding plate 40 away from the first sliding cylinder 38 is fixedly connected to a threaded cylinder 41. The threaded cylinder 41 is a metal cylinder with a threaded inner wall, and the inner wall of the threaded cylinder 41 is adapted to the outer wall profile of the threaded outer wall on the rotating rod 44, so the threaded cylinder 41 can be on the outer wall of the rotating rod 44. The fourth sliding column 42 is symmetrically fixedly connected to the outer walls of both sides of the first sliding cylinder 38. The fourth sliding column 42 consists of two parts: a metal cylinder and a metal circular plate. The outer walls of the two fourth sliding columns 42 are respectively rotatably connected with footrests 43. The footrests 43 consist of a slipper-shaped metal material part and a hollow metal cylinder part, wherein the slipper-shaped metal material part is used to support the patient's feet, and the inner wall contour of the hollow metal cylinder part is adapted to the outer wall contour of the fourth sliding column 42. Therefore, the footrest 43 can rotate on the outer wall of the fourth sliding column 42. When the patient's position is adjusted, as the patient's legs curl up, the footrest 43 will follow the foot and rotate slightly along the outer wall of the fourth sliding column 42, thereby avoiding spraining the patient's ankle. The footrest 43 is disclosed in the prior art and will not be described in detail. A first abutment block 39 is fixedly connected to the bottom outer wall of the first sliding cylinder 38. The first abutment block 39 is a trapezoidal metal block. A second sliding cylinder 34 is slidably connected to the outer wall of the second sliding column 26 near the first sliding cylinder 38. The second sliding cylinder 34 is a hollow metal cylinder with a square structure. The inner wall profile of the second sliding cylinder 34 matches the outer wall profile of the second sliding column 26, so that the second sliding cylinder 34 can slide on the outer wall of the second sliding column 26. First elastic plates 35 are symmetrically fixedly connected to the outer walls of the second sliding cylinder 34 on both sides. The first elastic plates 35 are C-shaped plastic plates. When the first elastic plates 35 are subjected to force, they will deform along the direction of their curvature. The two first elastic plates 35 are fixedly connected to the same first abutment plate 36 away from the second sliding cylinder 34. The first abutment plate 36 is a plastic plate with a curvature at one end and a chamfer at the other end. The inclined surface of the chamfered end of the first abutment plate 36 abuts against the inclined surface of the first abutment plate. A third avoidance groove 37 is provided on the top outer wall of the first contact plate 36 near the first elastic plate 35. The third avoidance groove 37 is a square groove body, and the inner wall contour of the third avoidance groove 37 is adapted to the outer wall contour of the second sliding cylinder 34, so the third avoidance groove 37 can avoid the second sliding cylinder 34.When the medical staff rotates the rotating handle 46 clockwise, the rotating rod 44 will rotate synchronously with the rotating handle 46. Since the threaded cylinder 41 is limited by the sliding plate 40 slidably connected to the third sliding groove 27, it will not rotate with the rotating rod 44, but will move along the outer wall of the rotating rod 44 in the direction away from the rotating handle 46. At the same time, it will drive the sliding plate 40 to slide along the inner wall of the third sliding groove 27 in the direction away from the rotating handle 46, and the first sliding cylinder 38 will slide along the outer wall of the second sliding column 26 under the drive of the sliding plate 40. At this time, the first abutment block 39 will abut against the chamfered inclined surface of the first abutment plate 36 under the drive of the first sliding cylinder 38. Under the guidance of the inclined surface of the first abutment block 39, the first abutment plate 36 will move in the direction away from the second sliding cylinder 34, so that the first elastic plate 35 will deform along its bending direction after being subjected to force until the first abutment block 39 is close to the second sliding cylinder 34. One side outer wall contacts the outer wall of the second sliding cylinder 34. At this time, the second sliding cylinder 34 will slide along the outer wall of the second sliding column 26, and the first contact plate 36 will move in the direction away from the rotating handle 46 under the drive of the second sliding cylinder 34. The fourth sliding column 42 will move synchronously with the first sliding cylinder 38, and the foot support plate 43 will also move in the direction away from the rotating handle 46 under the drive of the fourth sliding column 42. At this time, the patient's foot will move in the direction away from the rotating handle 46 of the patient under the drive of the foot support plate 43, and the patient's leg will slowly bend with the movement of the foot support plate 43. The above structural setting can not only drive the foot support plate 43 to move by rotating the rotating handle 46 to adapt to the leg length of different patients; the rotating handle 46 can also be rotated again to cooperate with the rotation of the turning pad 8 to adjust the curling angle of the patient's legs, thereby improving the comfort of different patient positions while meeting the surgical requirements.

[0051] The working process of the technical solution provided by the present invention is as follows:

[0052] During use, the medical staff first bends the turning pad 8 on the device to make the turning pad 8 rotate along the inner wall of the rotating circular hole 12 on the rotating connecting plate 11 close to the fourth avoidance groove 10 until it remains perpendicular to the holding tube 1, and then bends the two first curved plates 22 and the two second curved plates 30 to make them also remain perpendicular to the holding tube 1, and then pulls the first sliding column 16 to slide along the inner wall of the first sliding groove 3 toward the end away from the second sliding groove 5, and the sliding circular plate 14 will move along the inner wall of the first sliding cavity 2 with the first sliding column 16 in the direction away from the second sliding groove 5, and at the same time pull the cable 24, the cable 24 will pull the fixed circular plate 25 to move toward the second sliding groove 5, and the second sliding column 26 will slide along the inner wall of the second sliding groove 5 driven by the fixed circular plate 25.

[0053] Next, the medical staff places the device on the operating bed, places the patient's two thighs between the side supports and the middle support on the turning pad 8, and places the patient's feet on the foot support plate 43. If the patient's legs are too short, the rotating handle 46 can be rotated clockwise, and the rotating rod 44 will rotate synchronously. Because the threaded cylinder 41 is limited by the sliding plate 40 that is slidably connected to the third sliding groove 27, it will not rotate with the rotating rod 44, but will move along the outer wall of the rotating rod 44 in the direction away from the rotating handle 46, and at the same time drive the sliding plate 40 along the inner wall of the third sliding groove 27 in the direction away from the rotating handle 46. The first sliding cylinder 38 will slide along the outer wall of the second sliding column 26 driven by the sliding plate 40, and the fourth sliding column 42 will be displaced synchronously with the first sliding cylinder 38. The foot support plate 43 will also move in the direction away from the rotating handle 46 driven by the fourth sliding column 42 until the patient can place his feet on the foot support plate 43.

[0054] Then let the patient put his arms on the pad 17 and push one side of the turning pad 8 so that the device can drive the patient to turn over. During the turning process, the square plastic plate part of the device will contact the surface of the bed to form a support under the guidance of the first curved plate 22 and the second curved plate 30 with one end of the arc. Then the medical staff will turn the rotating handle 46 clockwise again, and the footrest plate 43 will continue to move away from the rotating handle 46 with the fourth sliding column 42. The patient's feet will move synchronously under the drive of the footrest plate 43, and the legs will gradually bend as the footrest plate 43 moves. At the same time, the first abutment block 39 will contact the chamfered inclined surface of the first abutment plate 36 under the drive of the first sliding cylinder 38, and the inclined surface of the first abutment block 39 will bend. Under the guidance of the first contact plate 36, the first contact plate 36 moves in the direction away from the second sliding cylinder 34, so that the first elastic plate 35 is deformed in its bending direction after being subjected to force, until the outer wall of the first contact block 39 close to the second sliding cylinder 34 contacts the outer wall of the second sliding cylinder 34. At this time, the second sliding cylinder 34 slides along the outer wall of the second sliding column 26, and the first contact plate 36 is driven by the second sliding cylinder 34 to move in the direction away from the rotating handle 46. The inclined surface of the second contact plate 13 is contacted by the first contact plate 36, so that the rotating connecting plate 11 rotates along the outer wall of the first rotating cylinder 7, and the turning pad 8 rotates with the rotating connecting plate 11 to lift the patient's thigh, thereby forming the body position required by the doctor for anesthesia.

[0055] After the operation is completed, the rotating handle 46 is rotated counterclockwise to drive the foot support plate 43 to move toward the rotating handle 46 until the sliding plate 40 slides along the inner wall of the third sliding groove 27 to one end close to the rotating handle 46. The patient's foot and thigh can be removed from the device, and then the device is removed from the operating table. After that, the first sliding column 16 is gently rotated to release the limit of the first sliding groove 3 on it, and the second sliding column 26 is pushed to slide along the inner wall of the second sliding groove 5 toward the second sliding cavity 31. At this time, the fixed circular plate 25 will pull the cable 24, and the cable 24 will pull the sliding circular plate 14 toward the second sliding groove 5 direction, the fixed circular plate 25 passes through the inner wall of the sliding circular plate 14 during the movement, and the first sliding column 16 slides along the inner wall of the first sliding groove 3 under the drive of the sliding circular plate 14, and then the first sliding column 16 is gently rotated again to slide it into the first sliding groove 3 close to the end of the second sliding groove 5 to form a limit, and then the turning pad 8 is bent to rotate it with the rotating circular hole 12 on the rotating connecting plate 11 close to the fourth avoidance groove 10 as the center of the circle until it is parallel to the holding tube 1, and then the first curved plate 22 and the second curved plate 30 are rotated respectively to make them also parallel to the holding tube 1 (as shown in FIG. Figure 3 ), you can complete the storage and reduce the space occupied by the device.
