[0030] Embodiment 1:

[0031] The specific working process of the present invention for anesthesia puncture is as follows:

[0032] (1) The mounting base 1 is fixedly mounted on the side of the bed, the anesthesia puncture device is fixed, and the puncture needle 2 is sequentially passed through the upper adjustment plate 8 and the lower adjustment plate 9 for installation.

[0033] (2) When the height of the puncture needle needs to be adjusted, the drive motor 3 can be started. The drive motor 3 drives the adjusting screw 4 to start rotating through the transmission assembly, so that the sliding block 5 slides up and down along the adjusting screw 4. The sliding block 5 drives the angle adjustment device and the puncture needle 2 to achieve automatic height adjustment.

[0034] Among them, the side of the sliding block 5 extends to form a guide block 29, and the inner wall of the protective shell 6 is provided with a guide groove body 7 that cooperates with the guide block 29. In the process of the sliding block 5 rising and falling along the adjusting screw rod 4, the guide block 29 on the sliding block 5 starts to slide along the guide groove body 7 inside the protective shell 6, thereby increasing the stability of the puncture needle during the height adjustment process.

[0035] The guide block 29 is a rectangular structure, and the guide slot body 7 is a rectangular slot body structure.

[0036] (3) When the angle of the puncture needle needs to be adjusted, two sets of telescopic connecting rods 10 are arranged between the upper adjustment plate 8 and the lower adjustment plate 9. The two sets of telescopic connecting rods 10 are distributed in a horizontal state. The two sets of telescopic connecting rods 10 drive the lower adjustment plate 9 to tilt by telescoping. Since the lower end of the puncture needle 2 is inserted on the lower adjustment plate 9, the angle of the puncture needle 2 is adjusted by tilting the lower adjustment plate 9. The telescopic connecting rods 10 are two sets of electric telescopic rods. The model of the electric telescopic rod is ElectrakEHA electric telescopic rod, which is mainly used for telescopic use in the structure of medical equipment, providing stable thrust to ensure safety and reliability during the lifting and lowering of the equipment. It is widely used in medical beds, operating tables, rehabilitation equipment, nursing beds, etc., and can meet the needs of height adjustment.

[0037] When the left telescopic connecting rod 10 is shortened, the lower adjustment plate 9 tilts to the lower right, and the puncture angle of the puncture needle 2 tilts to the lower left; when the right telescopic connecting rod 10 is shortened, the lower adjustment plate 9 tilts to the upper left, and the puncture angle of the puncture needle 2 tilts to the lower right. This embodiment can adjust the left and right tilt angles of the puncture needle 2.

[0038] When the height and angle of the puncture needle 2 are adjusted, the drive motor 3 and the telescopic connecting rod 10 can work simultaneously. The above structure can realize the simultaneous adjustment of the puncture needle and the angle. At the same time, only the drive motor 3 is used as the driving device, which solves the problems of insufficient control linkage of the angle and height and numerous driving devices in the prior art.

[0039] After the puncture needle 2 is adjusted to the corresponding angle, the puncture needle 2 can be used for puncture, and the puncture needle 2 is pushed to start the puncture work. The upper adjustment plate 8 and the lower adjustment plate 9 can guide the puncture of the puncture needle, thereby improving the puncture efficiency and accuracy of the puncture needle.

[0040] Embodiment 2:

[0041] The upper adjustment plate 8 is provided with a first threaded connecting rod 26 and a second threaded connecting rod 27, and the side of the sliding block 5 is provided with a threaded connecting hole 28 that cooperates with the first threaded connecting rod 26 and the second threaded connecting rod 27. The first threaded connecting rod 26 and the second threaded connecting rod 27 are distributed in a vertical state.

[0042] The second threaded connecting rod 27 can be threadedly connected to the side of the sliding block 5. At this time, the two groups of telescopic connecting rods 10 are distributed in a vertical state, which is perpendicular to the distribution state of the telescopic connecting rods in the first embodiment.

[0043] When the front telescopic connecting rod 10 is shortened, the lower adjusting plate 9 tilts backward and downward, and the puncture angle of the puncture needle tilts forward and downward; when the rear telescopic connecting rod 10 is shortened, the lower adjusting plate 9 tilts forward and downward, and the puncture angle of the puncture needle tilts backward and downward.

[0044] The rest of the adjustment process and method are the same as those in the first embodiment.

[0045] In order to facilitate the rotation adjustment of the puncture needle, the rotation adjustment device includes a rotating motor 16, a first rotating gear 17 and a second rotating gear 18. The output shaft of the rotating motor 16 is used to connect with the first rotating gear 17. The first rotating gear 17 and the second rotating gear 18 are meshed. The second rotating gear 18 is connected to the bottom end of the protective shell 6 through a fixed shaft. The rotating motor 16 drives the first rotating gear 17 to start rotating. The rotation of the first rotating gear 17 drives the meshed second rotating gear 18 to rotate. The rotation of the second rotating gear 18 drives the protective shell 6 to start rotating. The rotation of the protective shell 6 can drive the puncture needle to rotate. Among them, the model of the rotating motor 16 is JGB37-520, which is a small DC reduction motor, which is easy to drive.

[0046] In order to facilitate installation and fixation of the puncture device, the installation and fixation base 18 is provided with a threaded pipe 19 , the threaded pipe 19 is internally threadedly connected with a limiting screw 20 , and a pressing plate 21 is provided at the top of the limiting screw 20 .

[0047] The mounting and fixing base 18 is a U-shaped structure with a side opening.

[0048] A rotating handle 22 is disposed at the bottom end of the limiting screw 20 , and an integrally formed anti-skid pattern 23 is evenly distributed on the outer peripheral surface of the rotating handle 22 , and the cross section of the anti-skid pattern 23 is arc-shaped.

[0049] The pressing plate 21 is in a disc-shaped structure.

[0050] The above-mentioned installation and fixing base 18 can be installed and fixed with the open end facing the bed board, and then the rotating handle 22 is held by hand. The rotating handle 22 drives the limiting screw 20 to start threaded rotation along the threaded pipe 19 on the installation and fixing base 18, and the limiting screw 20 drives the pressing plate 21 to press and fix the installation and fixing base 18 on the side of the bed.

[0051] In order to enable the upper adjustment plate and the lower adjustment plate to be flexibly connected, a first rotating connection part 24 is provided at the bottom end of the upper adjustment plate 8, and a second rotating connection part 25 is provided at the top end of the lower adjustment plate 9. The first rotating connection part 24 and the second rotating connection part 25 have the same structure.

[0052] In order to facilitate the rotational connection between the first rotating connection part and the second rotating connection part, the first rotating connection part 24 includes two sets of parallel mounting plates 24-1, and circular holes 24-2 are opened on the mounting plates 24-1. The top end of the telescopic connecting rod 10 is inserted into the circular holes 24-2 on the mounting plates 24-1 through the rotating shaft. During the process of puncture positioning adjustment, circular holes 24-2 are set on both sets of mounting plates 24-1. No matter how the angles of the two sets of mounting plates 24-1 are adjusted, the upper and lower sets of circular holes 24-2 determine a straight line. After the position positioning adjustment of the upper and lower mounting plates 24-1 is completed, the puncture needle can be inserted from the two sets of circular holes 24-2 in sequence. The above structure will not cause the puncture needle to bend during the puncture process.

[0053] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
