Description

Technical Field

[0001] The present invention relates to the field of anesthetic injection, and particularly to a multifunctional anesthetic injection assistance tool. Background Art

[0002] Anesthetic injection is a commonly used anesthetic method in the medical process. It involves injecting anesthetic drugs into the patient's body through different routes to achieve an anesthetic effect. Different types of surgeries require different anesthetic methods and dosages. Before surgery, doctors will determine the most suitable anesthetic method and dosage based on factors such as the patient's condition, surgical site, age, physical condition, and surgical time, and the injection will be performed by a professional anesthesiologist.

[0003] After retrieval, the Chinese patent with the publication number CN118576821A discloses a multifunctional anesthetic injection assistance tool. Through the settings of structures such as a hinged pull block and a syringe, when anesthesia is needed, the anesthetic is placed in the syringe, and then the syringe is placed inside the outer frame. Subsequently, the hinged wax block is slowly pulled with the finger, so that the round push block pushes the push rod forward. Through the settings of the scale mark and the transparent cover, the pushed syringe can be observed in real time, improving the stability of its use. Through the above technical solution, the problems of unstable use and low injection accuracy in the prior art are solved. However, when this solution is actually used, there are still the following deficiencies: When performing the key medical step of lumbar injection anesthesia, since the needle required for lumbar injection anesthesia is relatively long, it requires medical staff to manually insert the needle accurately into the patient's lumbar interspace. This process not only takes a relatively long time, increasing the time cost of the surgery, but also has a relatively high operation difficulty. More importantly, if the medical staff is slightly careless during the operation and the needle becomes skewed, it may not only be unable to accurately inject the anesthetic drug into the target position, thus affecting the anesthetic effect, but also cause great pain and discomfort to the patient.

[0024] The present invention provides a technical solution. Referring to Figures 1 to 11 as shown, a multifunctional anesthetic injection auxiliary tool includes a bracket 1, an installation structure is provided on the bracket 1, two groups of driving components are symmetrically arranged on the bracket 1, and two groups of pinching components adapted to the driving components are symmetrically arranged on the bracket 1; The driving assembly includes a driving rod 31 arranged inside the bracket 1. A driving gear 32 is fixedly sleeved on the outer wall of the driving rod 31. A guiding frame 33 is fixedly installed on the inner wall of the bracket 1. A guiding block 34 is slidably installed on the inner wall of the guiding frame 33. A connecting rod 35 is fixedly installed on the side of the guiding block 34. A transmission rack 36 meshing with the driving gear 32 is fixedly installed at the end of the connecting rod 35. A connecting frame 37 is fixedly installed on the bottom surface of the connecting rod 35. An installation ring 38 is fixedly installed at one end of the two connecting frames 37 close to each other. A servo motor 39 is arranged at the end of one of the upper middle parts of the two driving rods 31. After the bracket 1 is installed, the anesthetic injection needle can be installed and fixed in the installation ring 38. After the anesthetic injection needle is installed, the end of the anesthetic injection needle has a certain distance from the patient's skin. Then, the anesthetic injection needle can be connected to the anesthetic injection pump. Subsequently, when the servo motor 39 is turned on, it can drive the driving rod 31 to rotate. When the driving rod 31 rotates, it can drive the driving gear 32 to rotate. The driving gear 32 meshes with the transmission rack 36, and thus can drive the transmission rack 36, the connecting rod 35 and the guiding block 34 to slide along the guiding frame 33, so that the anesthetic injection needle slides towards the direction close to the patient's skin.

[0025] Refer to Figure 1 , Figure 2 As shown in the figure, the installation structure includes auxiliary plates 21 fixedly installed at the four corner positions of the end of the bracket 1. A guiding sleeve 22 is fixedly installed at the bottom of the bracket 1. An adjusting screw 23 is slidably installed on the inner wall of the guiding sleeve 22. A threaded sleeve 24 is rotatably installed at the bottom end of the guiding sleeve 22, and the threaded sleeve 24 is screwed with the adjusting screw 23. A universal ball groove 25 is opened at the bottom end of the adjusting screw 23. A universal ball head 26 is movably installed on the inner wall of the universal ball groove 25. A supporting plate 27 is fixedly installed on the outer wall of the universal ball head 26. Medical patches 28 are bonded to the bottom surface of the supporting plate 27 and the side surfaces of the four auxiliary plates 21 respectively. The bracket 1 can be installed so that the bracket 1 is installed at the lumbar position of the patient. When installing, the bracket 1 can be aligned with the anesthetic injection position. Then, the threaded sleeve 24 is rotated. The threaded sleeve 24 is screwed with the adjusting screw 23, and the adjusting screw 23 is slidably connected with the guiding sleeve 22. Therefore, when the threaded sleeve 24 rotates, it can drive the adjusting screw 23 to slide, so that the supporting plate 27 at the bottom end of the adjusting screw 23 can be attached to the hospital bed. And with the cooperation of the universal ball groove 25 and the universal ball head 26, the supporting plate 27 can be tilted to ensure that the supporting plate 27 can be attached to the hospital bed and play a stable supporting role. Then, the medical patches 28 on the auxiliary plates 21 and the supporting plate 27 can be respectively bonded to the patient's skin and the hospital bed, and the bracket 1 can be limited and fixed.

[0026] Refer to Figures 3 to 6As shown in the figure, the pinching assembly includes a fixed frame 41 fixedly installed on the inner wall of the bracket 1. A sliding plate 42 is slidably installed on the inner wall of the fixed frame 41. A connecting frame 43 is fixedly installed on the inner wall of the bracket 1 at one end of the auxiliary plate 21. A push plate 44 is slidably installed on the inner wall of the connecting frame 43. A clamping block 45 is fixedly installed at one end of the push plate 44 located outside the connecting frame 43. One end of the sliding plate 42 is hinged with a transmission plate 46. The end of the transmission plate 46 away from the sliding plate 42 is hinged with the side surface of the push plate 44. An installation plate 47 is fixedly installed on the inner wall of the bracket 1. A reversing gear 48 is rotatably installed on the side surface of the installation plate 47 through a first installation rod. A transmission gear 49 meshing with the reversing gear 48 is rotatably installed on the side surface of the installation plate 47 through a second installation rod. A number of fixed teeth 410 meshing with the transmission gear 49 are arranged on the sliding plate 42. A connecting rack 411 meshing with the reversing gear 48 is fixedly installed at the end of the transmission rack 36. A limiting structure corresponding to the second installation rod is arranged on the side surface of the installation plate 47; Refer to Figures 6 to 7 As shown in the figure, the limiting structure includes a limiting shell 51 fixedly installed on the side surface of the installation plate 47. A rotating shaft 52 is rotatably installed on the inner wall of the limiting shell 51. A ratchet wheel 53 is fixedly sleeved on the outer wall of the rotating shaft 52. A first torsion spring 54 is sleeved on the end of the rotating shaft 52, and the two ends of the first torsion spring 54 are respectively fixedly connected with the rotating shaft 52 and the limiting shell 51. A shaft rod 55 is rotatably installed on the inner wall of the limiting shell 51. A pawl 56 meshing with the ratchet wheel 53 is fixedly sleeved on the shaft rod 55. A second torsion spring 57 is sleeved on the shaft rod 55, and the two ends of the second torsion spring 57 are respectively fixedly connected with the shaft rod 55 and the limiting shell 51. The end of the rotating shaft 52 passes through the side surface of the limiting shell 51 and is fixedly connected with the end of the second installation rod. The end of the shaft rod 55 passes through the side surface of the limiting shell 51. A triggering mechanism is arranged on the clamping block 45; Refer to Figures 7 to 8As shown, the triggering mechanism includes two guiding ports 61 symmetrically opened on the clamping block 45. A sliding rod 62 is slidably installed on the inner walls of the two guiding ports 61. One end of the two sliding rods 62 located outside the guiding ports 61 is fixedly installed with a clamping plate 63. A first spring 64 is sleeved on each of the two sliding rods 62, and the two ends of the first spring 64 are respectively fixedly connected to the clamping block 45 and the clamping plate 63. An extrusion airbag 65 is arranged between the clamping block 45 and the clamping plate 63. A transmission airbag 66 is fixedly installed on the side of the limit shell 51 through a support plate. The extrusion airbag 65 and the transmission airbag 66 are communicated through a conduit 67. One end of the shaft rod 55 located outside the limit shell 51 is fixedly installed with a lapping plate corresponding to the transmission airbag 66. As the transmission rack 36 slides, the connecting rack 411 can slide accordingly and drive the reversing gear 48 to rotate. The reversing gear 48 meshes with the transmission gear 49, and thus can drive the transmission gear 49 to rotate. And this rotation direction of the transmission gear 49 is the free state of the ratchet wheel 53 and the pawl 56. Therefore, the transmission gear 49 can rotate. When the transmission gear 49 rotates, it can drive the slide plate 42 to slide along the fixed frame 41 through the fixed teeth 410. During the sliding process of the slide plate 42, it can drive the transmission plate 46 to tilt and push the push plate 44, so that the push plate 44 slides along the connecting frame 43. The two clamping blocks 45 can approach each other, and during the approaching process, the skin at the injection position of the patient can be clamped by the clamping plate 63, ensuring that the subsequent needle is convenient to enter. With the drive of the servo motor 39, the injection needle continues to move and can enter the clamped skin. As the transmission rack 36 and the connecting rack 411 continue to move, the connecting rack 411 can be separated from the reversing gear 48. And at this time, as the clamping plate 63 clamps, the extrusion airbag 65 can be compressed. The gas in the extrusion airbag 65 after extrusion can enter the transmission airbag 66 through the conduit 67. After the transmission airbag 66 is inflated with gas and expands, it can push the lapping plate on the shaft rod 55, so that the shaft rod 55 rotates. When the shaft rod 55 rotates, the pawl 56 on it can be separated from the ratchet wheel 53, releasing the limit on the ratchet wheel 53. At this time, under the action of the first torsion spring 54, the rotating shaft 52 can reverse and drive the transmission gear 49 and the reversing gear 48 to reverse, so that the slide plate 42 slides in the opposite direction, and the clamping block 45 can be reset to release the patient's skin, so that the anesthetic injection needle can continue to be inserted.

[0027] Referring to Figures 3 to 9As shown in the figure, an indicating component is arranged on the support 1. The two driving rods 31 are connected by a driven wheel and a synchronous belt. One of the two driving rods 31 located at the lower part is rotatably connected to the support 1 through a connecting plate, and connecting mechanisms are arranged between both ends of the upper driving rod 31 and the support 1. The indicating component includes support plates 71 symmetrically and fixedly installed on the inner wall of the support 1. A pressing plate 72 is arranged on the top surfaces of the two support plates 71. Spring two 73 is fixedly installed between the bottom surface of the pressing plate 72 and the two support plates 71. A number of indicating rods 74 distributed in a linear array are arranged through the top surface of the pressing plate 72. Magnet one 75 is fixedly installed on the bottom surfaces of the number of indicating rods 74. A support rod 76 is fixedly installed on the outer wall of the mounting ring 38. Magnet two 77 is fixedly installed at the top end of the support rod 76. The magnetic poles of the magnet two 77 and the magnet one 75 facing each other are the same. A rotating rod 78 is rotatably installed on the side surface of the fixed frame 41. A pointer 79 is fixedly sleeved on the rotating rod 78; Refer to Figures 9 to 10 As shown in the figure, the connecting mechanism includes a fixing plate 81 fixedly installed on the inner wall of the support 1. An opening 82 is formed on the side surface of the fixing plate 81. A guiding plate 83 is slidably installed on the inner wall of the opening 82. The side surface of the guiding plate 83 is rotatably connected to the end of the driving rod 31. A number of spring three 84 are fixedly installed between the bottom surface of the guiding plate 83 and the inner bottom surface of the opening 82. A pressing rod 85 corresponding to the driving rod 31 is fixedly installed on the bottom surface of the pressing plate 72. A pressing sleeve 86 is fixedly installed at the bottom end of the pressing rod 85; During the process of inserting the anesthesia injection needle into the patient's lumbar vertebra, when the mounting ring 38 moves, it can drive the support rod 76 to move. When the support rod 76 moves below the magnet one 75, under the repulsive magnetic force of the magnet one 75 and the magnet two 77, the indicating rod 74 can be pushed up and protruded. Medical staff can judge the insertion degree of the anesthesia indicating needle by observing the indicating rod 74. And during the erection process of the support 1, the erection situation of the support 1 can be understood by observing the perpendicularity of the pointer 79. When the pointer 79 is perpendicular to the support 1, it means that the support 1 can be fixed, which is more convenient to use; And when an accident occurs during the insertion of the anesthesia injection needle, at this time, the medical staff can press the pressing plate 72 to make the pressing plate 72 move downward. During the downward movement of the pressing plate 72, the driving rod 31 can be pressed through the pressing rod 85 and the pressing sleeve 86, so that the guiding plate 83 at the end of the upper driving rod 31 can slide along the opening 82, so that the driving gear 32 is separated from the transmission rack 36, and then the driving of the anesthesia injection needle is stopped to cope with emergencies.

[0028] Working principle of the present invention: During use, first, the bracket 1 can be installed such that the bracket 1 is installed at the lumbar position of the patient. When installing, the bracket 1 can be aligned with the anesthetic injection position. Subsequently, the threaded sleeve 24 is rotated. The threaded sleeve 24 is screwed with the adjusting screw 23, and the adjusting screw 23 is slidably connected to the guiding sleeve 22. Therefore, when the threaded sleeve 24 rotates, it can drive the adjusting screw 23 to slide, so that the support plate 27 at the bottom end of the adjusting screw 23 can be in contact with the hospital bed. And with the cooperation of the universal ball groove 25 and the universal ball head 26, the support plate 27 can be tilted to ensure that the support plate 27 can be in contact with the hospital bed, playing a stable supporting role. Subsequently, the medical patches 28 on the auxiliary plate 21 and the support plate 27 can be respectively adhered to the skin of the patient and the hospital bed, and then the bracket 1 can be limited and fixed; after the bracket 1 is installed, the anesthetic injection needle can be installed and fixed in the mounting ring 38. After the anesthetic injection needle is installed, the end part has a certain distance from the skin of the patient. Then, the anesthetic injection needle is connected to the anesthetic injection pump. Subsequently, the servo motor 39 is started to drive the driving rod 31 to rotate. When the driving rod 31 rotates, it can drive the driving gear 32 to rotate. The driving gear 32 meshes with the transmission rack 36, and then it can drive the transmission rack 36, the connecting rod 35 and the guiding block 34 to slide along the guiding frame 33, so that the anesthetic injection needle slides towards the direction close to the skin of the patient; As the transmission rack 36 slides, the connecting rack 411 can slide accordingly and drive the reversing gear 48 to rotate. The reversing gear 48 meshes with the transmission gear 49, and thus can drive the transmission gear 49 to rotate. The rotation direction of the transmission gear 49 is the free state of the ratchet wheel 53 and the pawl 56. Therefore, the transmission gear 49 can rotate. When the transmission gear 49 rotates, it can drive the slide plate 42 to slide along the fixed frame 41 through the fixed teeth 410. During the sliding process of the slide plate 42, it can drive the transmission plate 46 to tilt and push the push plate 44, so that the push plate 44 slides along the connecting frame 43. The two clamping blocks 45 can approach each other, and during the approaching process, they can clamp the skin at the injection position of the patient through the clamping plate 63, ensuring that the subsequent needle is easy to enter. With the drive of the servo motor 39, the injection needle continues to move and can enter the clamped skin. As the transmission rack 36 and the connecting rack 411 continue to move, the connecting rack 411 can be separated from the reversing gear 48. And at this time, with the clamping of the clamping plate 63, the extrusion airbag 65 can be compressed. The gas in the extrusion airbag 65 after extrusion can enter the transmission airbag 66 through the conduit 67. After the transmission airbag 66 is inflated with gas, it can push the overlapping plate on the shaft rod 55, so that the shaft rod 55 rotates. When the shaft rod 55 rotates, the pawl 56 on it can be separated from the ratchet wheel 53, releasing the limit on the ratchet wheel 53. At this time, under the action of the first torsion spring 54, the rotating shaft 52 can reverse, and drive the transmission gear 49 and the reversing gear 48 to reverse, so that the slide plate 42 slides in the opposite direction, and the clamping blocks 45 can be reset to loosen the patient's skin, so that the anesthetic injection needle can continue to be inserted; During the process of inserting the anesthetic injection needle into the patient's lumbar spine, when the mounting ring 38 moves, it can drive the support rod 76 to move. When the support rod 76 moves below the first magnetic sheet 75, under the repulsive magnetic force of the first magnetic sheet 75 and the second magnetic sheet 77, the indicating rod 74 can be pushed up and protrude. Medical staff can judge the insertion degree of the anesthetic indicating needle by observing the indicating rod 74. And during the erection process of the bracket 1, the erection situation of the bracket 1 can be understood by observing the verticality of the pointer 79. When the pointer 79 is perpendicular to the bracket 1, it means that the bracket 1 can be fixed, which is more convenient to use; When an accident occurs during the insertion of the anesthetic injection needle, at this time, the medical staff can press the pressing plate 72 to make the pressing plate 72 move downward. During the downward movement of the pressing plate 72, it can press the driving rod 31 through the pressing rod 85 and the pressing sleeve 86, so that the guiding plate 83 at the end of the upper driving rod 31 can slide along the opening 82, so that the driving gear 32 is separated from the transmission rack 36, and then the driving of the anesthetic injection needle is stopped to cope with emergencies; After the anesthetic injection needle is completely inserted into the patient's lumbar spine and anesthetic is injected through the anesthetic pump, the servo motor 39 can be restarted to reverse to make the anesthetic injection needle pull out of the patient's lumbar spine.
