[0034] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0035] Example 1

[0036] like Figure 1-12 As shown, an anesthesia puncture fixator proposed by the present invention includes a support frame 1, fixing clamps 2 are installed at both ends of the support frame 1, an adjusting block 3 is movably connected to the outside of the support frame 1, a fixing bolt 4 is provided on the outside of the adjusting block 3, an adjusting box 5 is installed on one end of the adjusting block 3 located on the inner side of the support frame 1, a movable rod 6 is movably connected to the outside of the adjusting box 5, an anesthesia puncture fixation assembly is provided on the outside of the movable rod 6, the anesthesia puncture fixation assembly includes a fixing plate 14 symmetrically arranged on the movable rod 6, the internal thread of the movable rod 6 is connected to a second one-way threaded rod 19, a support plate 18 is installed on the end of the second one-way threaded rod 19, an anesthesia puncture guide assembly is provided on the outside of the support plate 18, and the anesthesia puncture guide assembly includes a guide ring 23, a guide groove 20 and a fixing groove 21 arranged on the support plate 18;

[0037] A first curved plate 24 is symmetrically provided on the inner side of the fixing groove 21, a second curved plate 27 is symmetrically provided on the inner side of the fixing groove 21, a rubber strip 38 is installed on the inner side of the two second curved plates 27, the outer side of the support plate 18 is movably connected to the second extrusion rod 33, the outer side of the support plate 18 is movably connected to the first extrusion rod 32, a circular ring 37 is provided on the inner side of the fixing groove 21, the inner side of the adjusting box 5 is rotatably connected to the first one-way threaded rod 7, the first one-way threaded rod 7 is threadedly connected to the movable rod 6, the outer side of the adjusting box 5 is rotatably connected to the first rotating rod 8, the outer side of the first one-way threaded rod 7 is installed with a second bevel gear 10, the first rotating rod 8 extends to one end of the inner side of the adjusting box 5 and is installed with a first bevel gear 9, and the first bevel gear 9 is meshed with the second bevel gear 10;

[0038] A through slot 11 is provided on the outside of the movable rod 6, and the two fixed plates 14 are slidingly connected to the through slot 11. The inner side of the through slot 11 is rotatably connected to a bidirectional threaded rod 12, and the fixed plate 14 is threadedly connected to the bidirectional threaded rod 12. The outside of the movable rod 6 is rotatably connected to a second rotating rod 15, and a third bevel gear 13 is installed on the outside of the bidirectional threaded rod 12. The second rotating rod 15 extends to one end inside the through slot 11 and is installed with a fourth bevel gear 16, and the third bevel gear 13 is meshed with the fourth bevel gear 16. Rubber blocks 17 are installed on the outside of the two fixed plates 14, and the shape of the fixed plate 14 is U-shaped.

[0039] The working principle of an anesthesia puncture fixator based on Example 1 is that when anesthesia puncture is required, the puncture position is first determined, and then the support frame 1 is fixed to the bed by the fixing clamp 2. At this time, the patient is lying on the bed and is on the inner side of the fixing clamp 2. The specific position can then be determined by sliding the adjusting block 3 on the fixing clamp 2 until the fixing plate 14 and the guide ring 23 are aligned with the puncture position. At this time, the position of the adjusting block 3 can be fixed by the fixing bolt 4, and then the first rotating rod 8 can be rotated, and the first bevel gear 9 is driven to rotate by the first rotating rod 8. Since the first bevel gear 9 and the second bevel gear 10 are meshed, the first one-way threaded rod 7 can be driven to rotate by the first bevel gear 9 and the second bevel gear 10 while rotating the first rotating rod 8. The force generated by the rotation of the first one-way threaded rod 7 drives the movable rod 6 to move, and at the same time, the fixing plate 14 is driven to move by the movable rod 6 until the fixing plate 14 is against the skin around the patient's puncture position;

[0040] At the same time, the friction between the fixing plate 14 and the skin is increased by the rubber block 17, so as to fix the patient and improve the stability during the puncture. If the position where the patient needs to puncture has a larger curvature, the second rotating rod 15 can be rotated at this time, and the fourth bevel gear 16 is driven to rotate by rotating the second rotating rod 15. Since the fourth bevel gear 16 is engaged with the third bevel gear 13, the bidirectional threaded rod 12 can be driven to rotate while rotating the second rotating rod 15. The force generated by the rotation of the bidirectional threaded rod 12 drives the two fixing plates 14 to move in the direction close to each other, so as to perform fine-tuning, thereby facilitating the use of fitting according to the curvature of different parts of the patient's body.

[0041] Example 2

[0042] like Figure 1-12As shown, based on the first embodiment, the guide groove 20 is opened on the outside of the support plate 18, the fixed groove 21 is opened on the outside of the support plate 18, and the guide groove 20 and the fixed groove 21 are connected. An L-shaped plate 22 is installed on the outside of the support plate 18, and a guide ring 23 is installed at the end of the L-shaped plate 22. The guide groove 20, the fixed groove 21 and the guide ring 23 are on the same horizontal line. The first telescopic rods 30 are symmetrically installed on the inner side of the fixed groove 21, and the ends of the two first telescopic rods 30 are fixedly connected to the ring 37.

[0043] A third spring 31 is symmetrically installed on the inner side of the fixing groove 21, and one end of the third spring 31 close to the ring 37 is fixedly connected to the ring 37. The outside of the support plate 18 is symmetrically slidably connected to the first connecting rod 25, and the outside of the first connecting rod 25 is installed with a first spring 26. The end of the first spring 26 close to the support plate 18 is fixedly connected to the support plate 18. The first curved plate 24 is installed at the end of the first connecting rod 25 that is located inside the fixing groove 21. The outside of the support plate 18 is symmetrically slidably connected to the second connecting plate 28, and the second curved plate 27 is installed at the end of the second connecting plate 28 that is located inside the fixing groove 21.

[0044] A fourth spring 34 is installed on the inner side of the first extrusion rod 32 and the second extrusion rod 33, and a second telescopic rod 39 is installed on the inner side of the first extrusion rod 32 and the second extrusion rod 33. The ends of the fourth spring 34 and the second telescopic rod 39 are fixedly connected to the support plate 18. A sliding groove 35 is provided on the outside of the first curved plate 24, and a sliding block 36 is slidably connected inside the sliding groove 35. The second curved plate 27 is installed on the outside of the sliding block 36, and a second spring 29 is installed on the outside of the sliding block 36. The end of the second spring 29 away from the sliding block 36 is fixedly connected to the side wall of the sliding groove 35.

[0045] In this embodiment, when the patient is punctured, the second one-way threaded rod 19 is rotated when the puncture position is determined. At this time, the support plate 18 is driven to rotate. Since the second one-way threaded rod 19 is threadedly connected to the movable rod 6, it has self-locking properties when rotated. At the same time, the slight displacement of the support plate 18 during rotation will not be affected. Therefore, it is easy to adjust the angle according to the puncture angle. During puncture, the puncture needle can pass through the guide groove 20 and the fixing groove 21, and at the same time pass through the guide ring 23, and then enter the patient's body. This guide effect can fix the puncture needle at a suitable angle, making the position of the puncture needle more accurate during puncture.

[0046] At the same time, during puncture, the first extrusion rod 32 can be pressed in the direction close to the support plate 18, and the second connecting plate 28 can be squeezed by the inclined surfaces at both ends of the first extrusion rod 32. At this time, the fourth spring 34 and the second telescopic rod 39 are contracted, and at the same time, the two second connecting plates 28 are driven to move in the direction of the support plate 18. When the second connecting plate 28 moves, it drives the second curved plate 27 to move along the sliding block 36 through the sliding groove 35. At this time, the second spring 29 is contracted and drives the rubber strip 38 to contact the anesthesia needle. By pressing the first extrusion rod 32 to control the contact force between the rubber strip 38 and the puncture needle, the force and speed of the puncture needle inserted into the patient's body can be adjusted, thereby improving the accuracy of the force during puncture.

[0047] When the puncture needle enters the patient's body, the injection tube of the puncture needle enters the fixed groove 21 and squeezes the ring 37. At this time, the third spring 31 and the first telescopic rod 30 shrink, and the ring 37 no longer limits the first curved plate 24. The first spring 26 in the stretched state is reset and the first curved plate 24 is reset by the first connecting rod 25. When the first curved plate 24 is reset, it drives the second curved plate 27 to move. When the second curved plate 27 moves, it drives the rubber strip 38 to squeeze the puncture needle. The injection tube of the puncture needle is then inserted, and the injection work is then performed. If the puncture is completed, the second squeezing rod 33 can be pressed, and the inclined surfaces at both ends of the second squeezing rod 33 can be used to squeeze the first connecting rod 25, thereby driving the optimistic first connecting rod 25 to move away from each other, and then the first curved plate 24 and the second curved plate 27 drive the rubber strip 38 to no longer squeeze the injection tube of the puncture needle. In this way, the puncture needle can be positioned during injection, which can effectively prevent the puncture needle from shaking, and prevent the puncture needle from shifting in the patient's body and causing excessive pain.
