Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to a precise positioning device for regional nerve block anesthesia. Background Art

[0002] Ultrasound-guided regional nerve block is a local anesthesia technique that blocks nerve conduction by injecting anesthetic drugs into specific nerve areas to achieve anesthesia and analgesia. This technique is often used in surgery and pain management to relieve pain during surgery and prolong pain-free time in the surgical area, while also reducing the choice of general anesthesia and its associated risks.

[0003] However, when the needle tip of the injection needle pierces the patient's injection site, the anesthetic in the syringe barrel is slowly pushed in. This process takes several minutes, and the needle tip of the injection needle must be fixed during the injection of the anesthetic, and it cannot move in any direction to avoid damaging the surrounding tissue structure. Therefore, when implementing regional nerve block, two anesthesiologists are usually required to cooperate with each other. One of the anesthesiologists needs to hold the ultrasound probe in one hand to reveal the position of the needle in the body, and the other hand needs to hold a specific posture for a long time to stabilize the puncture needle at the target position. The other anesthesiologist needs to push the drug at a uniform speed. This process is difficult to achieve single-person operation. With the increasing demand for medical services, this process not only affects the timely treatment of patients, but also increases the burden on medical staff. Based on this, we propose a precise positioning device for regional nerve block anesthesia to solve the above problems. Utility Model Content

When the movable plate 41 moves, it will drive the fixed seat 44 to move synchronously. The inner wall of the fixed seat 44 is elastically connected with a wedge block 46 through a limit spring 45. One end of the limit spring 45 is fixedly connected to the top of the inner wall of the fixed seat 44, and the other end of the limit spring 45 is fixedly connected to the surface of the wedge block 46. The function of the limit spring 45 is that when the wedge block 46 is pulled and moved, it can be driven to reset by its own elastic action. The wedge block 46 penetrates and is slidably connected to the inner wall of the fixed seat 44. A plurality of groups of card grooves are provided at the top of the outer wall of the movable plate 41. The bottom end of the outer wall of the wedge block 46 is engaged with the inner wall of the card groove. The engagement between the two fixes the fixed seat 44 at multiple positions moved on the surface of the movable plate 41. The bottom end of the outer wall of the movable plate 41 contacts the top of the outer wall of the vehicle body 1, and a rotating component 5 is provided inside the fixed seat 44.

[0038] Reference Figure 2-Figure 4 The rotating assembly 5 includes a rotating disk 51, and the outer wall of the rotating disk 51 is provided with multiple groups of through holes. The plug-in block 55 is plugged into the inner wall of the through hole. The plug-in between the two can fix the rotating disk 51 at multiple angles, so that the sliding seat 52 can be adjusted according to the patient's body position. The rotating disk 51 is rotatably connected to the outer wall of the fixed seat 44, and the plug-in block 55 is slidably connected to the inner wall of the fixed seat 44. The inner wall of the rotating disk 51 is slidably connected with the sliding seat 52, and the sliding seat 52 rises or falls on the inner wall of the rotating disk 51, so as to adjust the position of the needle tube according to the patient's posture. The inner wall of the sliding seat 52 is rotatably connected with a bolt 53, and the surface of the bolt 53 is threadedly connected with a clamping plate 56. The clamping plate 56 is moved on its inner wall by rotating the bolt 53, so as to cooperate with another group of fixed clamping plates 56 to fix the needle tube. The inner wall of the sliding seat 52 is connected by a spring 57 is elastically connected with a triangular block 58, and the clamping plate 56 is slidably connected to the inner wall of the sliding seat 52. One end of the connecting spring 57 is fixedly connected to the inner wall of the sliding seat 52, and the other end of the connecting spring 57 is fixedly connected to the outer wall of the triangular block 58. The function of the connecting spring 57 is to reset the position of the triangular block 58 after being squeezed and moved. The triangular block 58 is slidably connected to the inner wall of the sliding seat 52. The inner wall of the rotating disk 51 is provided with a plurality of groups of grooves. The triangular block 58 contacts the inner wall of the groove. The contact between the two prevents the sliding seat 52 from moving without being affected by external force. The inner wall of the fixed seat 44 is elastically connected with the plug-in block 55 through the reset spring 54. One end of the reset spring 54 is fixedly connected to the outer wall of the plug-in block 55, and the other end of the reset spring 54 is fixedly connected to the inner wall of the fixed seat 44. The function of the reset spring 54 is to reset the plug-in block 55 when it is moved.

[0039] Working principle: When injecting anesthetics to the patient, first move the vehicle body 1 to the position of the operating table through the four sets of universal wheels at the bottom of the vehicle body 1. At this time, the fixed seat 44 can be pushed to move on the surface of the movable plate 41. At the same time, during the movement of the movable plate 41, the inclined surface of the wedge block 46 on its inner wall can be separated from the inner wall of the slot at the current position of the movable plate 41, and squeezed by its inclined surface, so that the wedge block 46 can move upward on the inner wall of the fixed seat 44 until the position of the next set of slots is reached. The wedge block 46 will be elastically acted upon by the limit spring 45 to restore it to its initial position, thereby aligning the sliding seat 52 with the part of the patient where the anesthetic needs to be injected. At the same time, when injecting the patient, the threaded rod 42 can be rotated to rotate its thread, so that the position of the sliding seat 52 can avoid the patient's blood vessels.

[0040] At the same time, the angle of the sliding seat 52 can be adjusted according to the injection position of the patient, and the plug block 55 can be pulled to disengage it from the through hole of the rotating disk 51, so that the rotating disk 51 drives the sliding seat 52 to rotate, and the angle can be adjusted according to the injection site of the patient. After the adjustment is completed, the plug block 55 is released and it will be elastically acted upon by the reset spring 54 to restore it to its initial position to be plugged into the through hole of the current position of the rotating disk 51, thereby fixing the position of the rotating disk 51. After the fixation is completed, the anesthetic syringe is placed inside the sliding seat 52, and the bolt 53 is rotated to move the clamping plate 56 toward another set of fixed clamping plates 56, thereby fixing the needle tube. At this time, the sliding seat 52 can be directly pulled downward on the inner wall of the rotating disk 51, so that the triangular block 58 is disengaged from the slot at the current position and is squeezed by the slot until the position of the next set of slots is reached, and the triangular block 58 is elastically acted upon by the connecting spring 57 to restore it to its initial position, thereby fixing the needle tube driven by the sliding seat 52 at the current position.
