The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1 to 4, an epidural anesthesia device according to an embodiment of the invention comprises:
The alignment assembly comprises a mounting frame and an alignment frame arranged on the mounting frame, wherein the alignment frame comprises a guide part 21 rotatably arranged on the mounting frame and a moving part 22 slidably arranged on the guide part 21, a fixed groove 22a is formed in the moving part 22, a puncture needle is detachably arranged in the fixed groove 22a, and a moving handle is arranged on one side of the moving part 22;
The clamping assembly comprises two movable guide rails 51 respectively arranged on two opposite sides of the movable portion 22, and first sliding blocks 52 slidably arranged on the movable guide rails 51, wherein clamping blocks 53 are arranged on one side, which is relatively close to the two first sliding blocks 52, of the movable handle, the movable handle comprises connecting portions 23b fixed on two opposite sides of the movable portion 22 at intervals, and holding portions 23a arranged between the two connecting portions 23b, second sliding blocks 61 are slidably arranged on the connecting portions 23b, protruding columns 64 are arranged on one side of the bottom of the first sliding blocks 52, one side of each second sliding block 61 is provided with an adjusting block 62 through a connecting rod 65, limiting grooves corresponding to the protruding columns 64 are formed in the adjusting blocks 62, movable rods 63 which are correspondingly arranged on the holding portions 23a are arranged between the two second sliding blocks 61, and the movable rods 63 are used for moving the adjusting blocks 62, so that the first sliding blocks 52 move relative to the movable guide rails 51 under the contact fit of the limiting grooves and the protruding columns 64, and two anesthetic tubes 53 are driven to be mutually clamped.
Preferably, in this embodiment, the clamping assembly further includes a fixing plate 54 fixed on the moving portion 22, a guide rod 55 is disposed on one side of the fixing plate 54, a sub-slider 57 disposed corresponding to the guide rod 55 is disposed on the first slider 52, a spring 56 is sleeved on the guide rod 55, and two ends of the spring 56 are connected to the sub-slider 57 and the fixing plate 54.
Specifically, in some application scenarios of the present embodiment, when a physician is performing epidural anesthesia, the needle is first accurately positioned to the target location by the alignment assembly. Once the needle is properly placed, the physician may begin an attempt to place the anesthetic tube. However, in practice, anesthesia catheter placement may encounter resistance due to the patient's posture, spinal structure, or other factors, resulting in placement difficulties. In this case, the physician needs to adjust the strategy to take into account withdrawal of the anesthetic tube and the needle. At this time, the function of the clamping assembly is highlighted. The doctor can slide the two first sliders 52 on the moving rail 51 by operating the moving handle. Since the first slider 52 is provided with the sub slider 57 corresponding to the guide bar 55 and the guide bar 55 is sleeved with the spring 56, when the doctor pulls the moving bar 63, the spring 56 is compressed to generate a certain resistance. Such resistance may help the physician perceive a change in the position of the first slider 52, thereby more accurately controlling the movement of the clamping block 53. When the first slider 52 is moved into position, the two clamping blocks 53 will come close to each other, clamping the anesthetic tube. At this time, due to the arrangement of the guide rod 55 and the sub-slider 57, the clamping force of the clamping block 53 on the anesthetic tube can be more uniform and stable, and the risk of damage to the tube during the withdrawal process is reduced. In addition, due to the presence of the spring 56, when the doctor releases the moving handle, the spring 56 is restored to the original state, pushing the sub slider 57 and the first slider 52 back to the original position. Thus, the doctor can conveniently perform the next anesthesia operation. The clamping component of the epidural anesthesia device not only improves the control capability of doctors on synchronous withdrawal of an anesthesia catheter and a puncture needle, but also reduces the risk of damage to the catheter in the withdrawal process through the arrangement of the guide rod 55, the sub-sliding block 57 and the spring 56. This makes the epidural anesthesia procedure safer, more efficient and more comfortable.
It will be appreciated that, through the above arrangement, holding the moving handle and simultaneously hooking the thumb on the moving rod 63 is equivalent to completing the synchronous control of the puncture needle and the anesthetic tube, and when in use, only the fist holding mode is needed, and the moving handle is pulled to complete the synchronous withdrawal of the puncture needle and the anesthetic tube, thereby conforming to the daily operation habit and having higher operation efficiency.
Further, in this embodiment, the alignment assembly further includes a pad 11, one side of the pad 11 is provided with an adjusting rail 13 through an L-shaped connecting frame 12, and the adjusting rail 13 is provided with the mounting frame in a sliding manner. In some application scenarios of this embodiment, the whole device is fixed by setting the pad 11 on the mattress or directly on the underside of the back of the patient, and the mounting frame is slidably disposed on the adjusting rail 13, so that the mounting frame and the alignment frame on the mounting frame are close to the patient, and anesthesia operation is facilitated.
Specifically, in the present embodiment, the mounting frame includes a base portion 14 slidably disposed on the adjustment rail 13, and a body portion 15 disposed on both sides of the base portion 14. The body portions 15 on both sides of the base portion 14 enclose an operation region corresponding to the operation.
Preferably, in this embodiment, the body portion 15 is provided with an adjusting groove, an adjusting screw 31 is disposed in the adjusting groove, a lifting block 32 disposed corresponding to the adjusting groove is screwed onto the adjusting screw 31, and the alignment frame is rotatably disposed on the lifting block 32. After finishing the regulation of mounting bracket, make the mounting bracket laminating be close to the patient, through rotating adjusting screw 31, adjust the height of elevating block 32 and counterpoint frame to guarantee to advance needle regional accuracy.
Further, in this embodiment, a clamping member is further disposed between the lifting block 32 and the alignment frame, and the clamping member includes a clamping bolt disposed between the guiding portion 21 and the lifting block 32, and a clamping nut 33 screwed to the clamping bolt. After the height adjustment of the lifting block 32 is completed, the alignment frame is swung, and the guide part 21 is fixed based on the abutting of the clamping nut 33 on the guide part 21, so that the needle feeding angle is adjusted, and the stability of needle feeding and needle withdrawing is ensured.
Preferably, in this embodiment, an alignment plate 42 is disposed on one side of the lifting block 32 through a fixing block 41, an operation opening 43 is formed in the alignment plate 42, and a stop belt 44 disposed corresponding to the operation opening 43 is further disposed on the alignment plate 42. In some application scenarios of the present embodiment, by providing the stop belt 44, the skin at the needle insertion position can be pressed instead of a human hand during the needle withdrawal operation, and the operation efficiency and the operation effect can be improved.
