Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more particularly to an anesthesia puncture positioning device capable of improving stability. Background Art

[0002] During surgical treatment in the pain department, the patient is usually anesthetized. Anesthetic puncture is a common preoperative work in pain department surgery. It is mainly used to anesthetize patients and reduce pain during surgery. The anesthesia positioning point is difficult to find, and the injection of liquid needs to be maintained for a period of time. Clinically, when performing anesthesia puncture on patients, it is necessary to fix the needle with one hand and press the push-pull rod with the other hand. This operation is more troublesome. Currently, medical staff often use tape to fix the needle when using it. However, if the patient moves or the user has a slight movement, it is easy to cause problems such as misalignment and wrong puncture, causing damage to the patient.

[0003] Chinese patent authorization announcement number: CN115956987A provides an anesthesia puncture positioning device, which, by setting a support frame, a connecting rod, and a mounting frame, prevents the support mechanism from contacting the patient's body, thereby avoiding the accuracy of puncture being affected by the patient's movements; by setting a hose, when the doctor performs an injection, the slight vibration of the doctor's arm is transmitted to the first syringe through the hose and eliminated, thereby avoiding the injection process being affected by the shaking of the doctor's arm during the injection process. The spherical ball joint is installed on the mounting frame, and the mounting frame can be adjusted in the horizontal and vertical directions, so that the positioning device can be injected from any position and angle, thereby improving the scope of application of the positioning device. However, the following defects still exist in the specific implementation process: when the device is used to perform anesthesia puncture on patients in clinical practice, first of all, there is a problem of inconvenient adjustment, and it cannot be adjusted according to the use requirements. Secondly, the needle tube position of the device cannot be fixed after the adjustment is completed. When injecting anesthetic drugs, the needle tip is prone to offset, which will cause injection deviation and poor stability.

[0004] Therefore, in order to solve the above problems, an anesthesia puncture positioning device which can improve stability is proposed. Summary of the invention

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components.

[0035] Example:

[0036] See also Figure 1-8 An anesthesia puncture positioning device capable of improving stability comprises two support plates 1, the upper ends of the two support plates 1 are fixedly connected to an anesthesia bed 2, the ends of the two support plates 1 away from each other are fixedly connected to a slide bar 3, the outer surfaces of the two slide bars 3 are slidably connected to a positioning mechanism 5, and the upper end of the anesthesia bed 2 is fixedly connected to two guard plates 4.

[0037] This solution supports the anesthesia bed 2 through two support plates 1. When performing anesthesia puncture in the pain department, the patient can lie on the anesthesia bed 2, and then push the positioning mechanism 5 according to the specific position where the patient needs anesthesia, so that the positioning mechanism 5 can slide along the outer surfaces of the two slide bars 3, allowing the device to complete anesthesia puncture of different parts.

[0038] See also Figure 2-5 The positioning mechanism 5 includes two connecting rods 51. Two sliding grooves 52 are provided at the ends of the two connecting rods 51 close to each other. The inner surfaces of the four sliding grooves 52 are slidably connected to the outer surfaces of the two slide bars 3 respectively. The ends of the two connecting rods 51 close to each other are fixedly connected with connecting blocks 53. The ends of the two connecting blocks 53 close to each other are commonly fixedly connected with a transverse movement component 54. The upper part of the transverse movement component 54 is fixedly connected with a lifting component 55. The outside of the lifting component 55 is fixedly connected with an adjustment component 56.

[0039] The transverse movement assembly 54 includes a rack 541, and the left and right ends of the rack 541 are respectively fixedly connected to one end of the two connecting blocks 53 that are close to each other. The outer surface of the rack 541 is meshingly connected with a driving member 543, and the driving member 543 is internally slidably connected to two guide bars 542. The left and right ends of the two guide bars 542 are respectively fixedly connected to one end of the two connecting blocks 53 that are close to each other.

[0040] The driving member 543 includes a motor 5431, the output end of the motor 5431 is fixedly connected to a gear 5432 via a coupling, the outer surface of the gear 5432 is meshed with the outer surface of the rack 541, the front end of the motor 5431 is fixedly connected to a moving frame 5433, the upper and lower walls of the inner cavity of the moving frame 5433 are fixedly connected to sliders 5434, the inner surfaces of the two sliders 5434 are respectively slidably connected to the outer surfaces of the two guide bars 542, and the inner surface of the moving frame 5433 is fixedly connected to four guide tubes 5435.

[0041] This solution starts the motor 5431 to allow the gear 5432 to rotate under the action of the motor 5431. Since the outer surface of the gear 5432 is meshed with the outer surface of the rack 541, and the position of the rack 541 is fixed, when the gear 5432 rotates, it can move left or right along the outer surface of the rack 541 with the cooperation of the two sliders 5434 and the two guide bars 542, thereby adjusting the position of the movable frame 5433, so that the point of anesthesia can be more precise.

[0042] The lifting assembly 55 includes a hydraulic cylinder 551, the lower end of the hydraulic cylinder 551 is fixedly connected to the upper end of the movable frame 5433, the output end of the hydraulic cylinder 551 is fixedly connected to a transmission plate 552, the lower end of the transmission plate 552 is fixedly connected to four sliding rods 553, the outer surfaces of the four sliding rods 553 are respectively slidably connected to the inner surfaces of the four guide tubes 5435, and the outer surfaces of the four sliding rods 553 are commonly fixedly connected to a connecting plate 554.

[0043] By starting the hydraulic cylinder 551, the transmission plate 552 can move downward under the action of the hydraulic cylinder 551. When the transmission plate 552 moves downward, it will push the four sliding rods 553 to move downward along the inner surfaces of the four guide tubes 5435 respectively, so that the position of the adjustment component 56 is lowered and closer to the patient's skin surface, which can make the device more stable.

[0044] The adjustment component 56 includes a positioning plate 561, the inner surface of the positioning plate 561 is fixedly connected to the outer surfaces of the four sliding rods 553, the lower end of the positioning plate 561 is fixedly connected to the steering motor 2 562, the lower end of the steering motor 2 562 is fixedly connected to the clamping plate 563, the output end of the steering motor 2 562 is fixedly connected to the connecting frame 1 564 through a coupling, the inner surface of the clamping plate 563 is threadedly connected to the adjusting nut 1 565, the inner surface of the connecting frame 1 564 is slidably connected to the adjusting member 566, and the outer surface of the adjusting member 566 is threadedly connected to the positioning member 567.

[0045] The adjusting member 566 includes a second connecting frame 5661, the outer surface of the second connecting frame 5661 is slidably connected to the inner surface of the first connecting frame 564, the front end of the second connecting frame 5661 is fixedly connected to a steering motor 3 5662, the output end of the steering motor 3 5662 is fixedly connected to a connecting frame 3 5663 via a coupling, and the inner surface of the connecting frame 3 5663 is slidably connected to a connecting nut 5664.

[0046] The positioning member 567 includes a connecting frame 4 5671, the inner surface of the connecting frame 4 5671 is threadedly connected to the outer surface of the connecting nut 5664, the front end of the connecting frame 4 5671 is fixedly connected to a steering motor 4 5672, the output end of the steering motor 4 5672 is threadedly connected to an adjusting nut 2 5673 through a coupling, the outer surface of the adjusting nut 2 5673 is slidably connected to a connecting frame 5 5674, and the inner surface of the connecting frame 5 5674 is fixedly connected to a positioning tube 5675.

[0047] In this scheme, by starting the steering motor 2 562, the connecting frame 1 564 can be rotated under the action of the steering motor 2 562, by starting the steering motor 3 5662, the connecting frame 3 5663 can be rotated under the action of the steering motor 3 5662, and by starting the steering motor 4 5672, the connecting frame 5 5674 can be rotated under the action of the steering motor 4 5672. In order to make the device suitable for some positions with smaller needle insertion angles, during use, the rotation radius of the connecting frames 1 564, 3 5663 and 5674 can be changed by loosening the adjusting nut and then increasing or decreasing the length between the connection points, so as to further improve the accuracy of anesthesia puncture. With the cooperation of the three steering motors, the positioning tube 5675 can be offset to any angle, and when the steering motor completes the steering, it will be locked without loosening, so that the stability of the device is higher. After the adjustment is completed, the anesthesia syringe only needs to be pushed forward along the inner surface of the positioning tube 5675, and the needle is inserted into the patient's skin to complete the injection.

[0048] It should be noted that the specific installation methods, circuit connection methods, oil circuit connection methods and control methods of motor 1 5431, hydraulic cylinder 551, steering motor 2 562, steering motor 3 5662 and steering motor 4 5672 in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0049] Working principle: When performing anesthesia puncture in the pain department, let the patient lie on the anesthesia bed 2. According to the specific position where the patient needs anesthesia, the cooperation of four slide grooves 52 and two slide bars 3 is used to push the two connecting rods 51 to adjust the front and rear accuracy of the device when in use. Start the motor 5431 to allow the gear 5432 to rotate under the action of the motor 5431. When the gear 5432 rotates, it can move left or right along the outer surface of the rack 541 under the cooperation of the two sliders 5434 and the two guide bars 542, thereby adjusting the position of the mobile frame 5433. In order to adjust the left and right precision of the device when in use, the hydraulic cylinder 551 is started, and the transmission plate 552 is moved downward under the action of the hydraulic cylinder 551. When the transmission plate 552 moves downward, it will push the four slide bars 553 to move downward along the inner surfaces of the four guide tubes 5435 respectively, so that the position of the adjustment component 56 is lowered, and the up and down precision of the device when in use can be adjusted. The three can be adjusted at the same time, so that the adjustment component 56 can be moved to any position corresponding to the anesthesia bed 2. No matter where the part of the patient's body that needs anesthesia is, the device can work, and the stability of the device itself is also guaranteed.

[0050] Finally, under the action of the three steering motors, the positioning tube 5675 can be offset to any angle, and when the steering motor completes the steering, it will be locked without loosening, making the device more stable. After the adjustment is completed, only the anesthesia syringe needs to be pushed forward along the inner surface of the positioning tube 5675, and the needle needs to be inserted into the patient's skin to complete the injection. This can improve the stability of the anesthesia injection and effectively avoid slight movements of the patient or doctor that may cause deviation or error in the injection.

[0051] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
