[0002] The anesthetic needle used in the anesthesia department is a special medical tool used to anesthetize patients during surgery or treatment. At the same time, in order to ensure that the depth of the needle can be accurately controlled and that the anesthetic drug reaches the target area accurately, a needle insertion device is generally used to inject the anesthetic needle.

[0003] The existing anesthesia needle insertion device for anesthesia department generally installs the syringe inside the device, and then drives the syringe to move inside the device through the propulsion mechanism inside the device, so that the syringe drives the needle to move, thereby realizing the needle insertion operation.

[0004] When using the existing needle insertion device, due to the differences in body shape of different patients, the required needle insertion depth will also be different. The doctor needs to accurately control the needle insertion depth according to the specific situation of the patient to ensure the anesthetic effect. The above-mentioned needle insertion device requires medical staff to control the needle insertion depth. It is difficult for the doctor to ensure the consistency of the needle insertion depth each time during the operation, resulting in poor anesthetic effect, which in turn causes complications. In addition, the existing anesthetic needle insertion device is generally injected manually by the doctor. It is difficult for the doctor to maintain a constant injection speed, resulting in uneven distribution of the anesthetic drug in the target area, causing discomfort to the patient.

[0005] To this end, the present invention provides an anesthesia needle insertion device for anesthesia department. Summary of the Invention

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. The anesthesia needle insertion device described in the present invention is configured to provide a limit assembly, adjust the position of the limit plate and fix it on the fixed rod, and then push the assembly to drive the limit rod to slide inside the fixed rod, the limit rod drives the clamping block to move, the clamping block drives the syringe to move, and the limit rod moves until the limit plate stops moving, so that the needle insertion length can be adjusted as needed.

[0019] 2. The anesthesia needle insertion device described in the present invention is provided with a propulsion component. When the needle needs to be inserted, the push frame drives the slide groove to move, and the first limit end of the slide groove drives the limit rod to slide, so that the limit rod drives the syringe inside the clamping block to move synchronously.

At this time, the push frame drives the splint to drive the syringe piston to move, and the injection operation can be realized. This device can automatically push the piston to perform the drug injection operation after pushing the syringe to insert the needle, avoiding the doctor's manual operation of needle insertion and injection, which leads to unstable operation and errors.

[0020] 3. The present invention describes an anesthetic needle insertion device for anesthesia department. When the protrusion moves to the block, the block squeezes the protrusion, causing the push frame to drop again, and the limit rod slides to the second limit section.

This device can automatically withdraw the needle, avoiding the problem of improper operation during manual needle withdrawal, which leads to needle bending, breakage or damage to patient tissue. At the same time, the piston is in the syringe, which avoids the backflow of the liquid medicine in the syringe. The residual liquid medicine cannot be effectively utilized, resulting in the actual amount of medicine injected into the patient's body being less than expected, thereby reducing the anesthetic effect on the patient.

[0021] 4. The anesthesia needle insertion device for anesthesia department described in the present invention is provided with a rotating assembly. When the limit rod is in the sliding section, the limit rod can be limited by the second rotating plate to prevent movement, causing the clamping block to drive the syringe to move. When the push plate is reset, the first rotating plate can limit the push plate, so that the slide groove is in the second limiting section to drive the syringe to withdraw the needle.

[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0038] Example 1

[0039] like Figures 1 to 9 As shown, an anesthesia needle insertion device for anesthesia according to an embodiment of the present invention includes a control component 10, on which a propulsion component 20, a limiting component 40 and a clamping component 30 are sequentially provided;

[0040] like Figures 4 to 9 As shown, the propulsion assembly 20 includes a pushing frame 22, one side of the pushing frame 22 is provided with an inclined edge, the pushing frame 22 is provided with a slide groove 23, the slide groove 23 includes a first limiting section 231, one side of the first limiting section 231 is provided with a sliding section 232, one side of the sliding section 232 is provided with a second limiting section 233, the first limiting section 231 and the second limiting section 233 are vertically arranged, the sliding section 232 is horizontally arranged, and one side of the pushing frame 22 is fixedly connected to a splint 222.

[0041] like Figure 3 As shown, the clamping assembly 30 includes a clamping block 31 , one side of the clamping block 31 is fixedly connected to a slide rod 32 , one end of the slide rod 32 is fixedly connected to a limit rod 33 , and a syringe 50 is clamped inside the clamping block 31 .

[0042] like Figure 6 As shown, the limiting assembly 40 includes a limiting plate 41, a protrusion 44 is fixedly connected to one side of the limiting plate 41, the internal rotation of the limiting plate 41 is connected to a rotating assembly 42, the rotating assembly 42 and the limiting plate 41 are fixedly connected by a torsion spring 43, and the internal rotation of the limiting plate 41 is connected to a bolt 45.

[0043] The control component 10 drives the pushing frame 22 to slide, and the pushing frame 22 drives the slide 23 to slide synchronously, and the slide 23 drives the limit rod 33 to move, and the limit rod 33 drives the slide rod 32 and the syringe 50 inside the clamping block 31 to slide synchronously. When the limit rod 33 is blocked by the limit component 40, the needle insertion operation of the syringe 50 is completed, and then the pushing frame 22 is driven by the limit component 40 to drive the slide 23 to slide toward one side of the clamping plate, and then the pushing frame 22 drives the piston of the syringe 50 inside the clamping plate to move for the injection operation. After the injection is completed, the pushing frame 22 is driven by the limit component 40 to drive the slide 23 to slide away from one side of the clamping plate, so that the slide 23 drives the limit rod 33 to slide, and the needle withdrawal operation can be completed.

[0044] Specifically, the existing anesthesia needle insertion device for anesthesia department generally installs a syringe 50 inside the device, and then drives the syringe 50 to move inside the device through the propulsion mechanism inside the device, so that the syringe 50 drives the needle to move, thereby achieving the needle insertion operation;

[0045] When using the above-mentioned existing needle insertion devices, due to the differences in body shapes of different patients, the required needle insertion depth will also vary. The doctor needs to accurately control the needle insertion depth according to the specific conditions of the patient to ensure the anesthetic effect. The above-mentioned needle insertion devices require medical staff to control the needle insertion depth. It is difficult for the doctor to ensure the consistency of the needle insertion depth each time during the operation, resulting in poor anesthetic effect and complications. In addition, the existing anesthetic needle insertion devices are generally injected manually by the doctor. It is difficult for the doctor to maintain a constant injection speed, resulting in uneven distribution of the anesthetic drug in the target area, causing discomfort to the patient.

[0046] In order to avoid the above problems, the present device is used as follows: when in use, the syringe 50 is placed in the interior of the clamping block 31, and one end of the piston is placed in the interior of the clamping plate 222. After the placement is completed, the limit plate 41 is adjusted to slide on the fixing rod 12 and the limit plate 41 is fixed by the bolt 45 to adjust the required needle insertion length. Then, when it is necessary to control the needle insertion operation, the push frame 22 can be driven to slide, and the push frame 22 drives the slide groove 23 to slide synchronously. In the initial state, the limit rod 33 is in the first limit section of the limit groove. 231, then the push frame 22 slides toward one side of the clamping block 31, the push frame 22 drives the slide 23 to slide synchronously, the slide 23 drives the limiting rod 33 to slide synchronously through the first limiting section 231, the limiting rod 33 drives the slide rod 32 to slide inside the fixed rod 12, the slide rod 32 drives the syringe 50 inside the clamping block 31 to slide synchronously, and the syringe 50 drives the needle to move. When the first limiting section 231 pushes the limiting rod 33 to slide to the limiting plate 41, the limiting plate 41 limits the limiting rod 33, and the required needle insertion length is completed at this time;

[0047] When the injection operation is required, the pushing frame 22 drives the limit rod 33 to move to the limit plate 41, and the protrusion 44 at the limit plate 41 contacts the inclined edge of the pushing frame 22, and the protrusion 44 squeezes the inclined edge of the pushing frame 22, causing the pushing frame 22 to slide toward one side of the splint 222. At this time, the limit rod 33 slides from the first limit section 231 to the sliding section 232, and then the protrusion 44 squeezes the pushing frame 22, and the pushing frame 22 continues to slide, and the pushing frame 22 drives the sliding section 232 of the slide groove 23 to slide synchronously. At this time, the splint 222 drives the piston of the syringe 50 to move toward the inside of the syringe 50, and the piston discharges the liquid inside the syringe 50, and the liquid injection operation is completed.

[0048] This device can precisely adjust the position of the limit plate 41 and control the insertion length of the syringe 50, thereby facilitating more accurate positioning of the anesthesia point during anesthesia, improving the anesthesia effect, and avoiding the problem of poor anesthesia effect due to inconsistent needle insertion depth. After pushing the syringe 50 into the needle, this device can automatically push the piston to perform the drug injection operation, avoiding the doctor's manual operation of needle insertion and injection, resulting in uneven distribution of anesthetic drugs in the target area, thereby causing discomfort to the patient.

[0049] like Figure 4 As shown, the propulsion assembly 20 further includes a push plate 21 , which is slidably connected to one side of a push frame 22 , and a spring 24 is fixedly connected between the push frame 22 and the push plate 21 .

[0050] Specifically, when the pushing frame 22 is pressed by the protrusion 44 , the pushing frame 22 slides on the pushing plate 21 and presses the spring 24 . The spring 24 can drive the pushing frame 22 to return to its initial position when the pushing frame 22 is reset.

[0051] Example 2

[0052] like Figures 8 and 9 As shown, compared with Example 1, another embodiment of the present invention is: a protrusion 221 is fixedly connected to the upper surface of the pushing frame 22, one end of the protrusion 221 is set to an arc shape, and the rotating assembly 42 includes a first rotating plate 421 rotatably connected to the inside of the limiting plate 41, and a second rotating plate 422 is fixedly connected to one side of the first rotating plate 421.

[0053] Specifically, when the needle insertion device is reset after the injection is completed, it needs to drive the piston to reset. The reset movement inside the syringe 50 will generate negative pressure, causing the liquid medicine to flow back. The residual liquid medicine cannot be effectively utilized, resulting in the actual amount of medicine injected into the patient's body being less than expected, thereby reducing the anesthetic effect on the patient.

[0054] When the first and second cams 421 are in contact with each other, the first and second cams 422 are in contact with each other, so that the first and second cams 422 can move relative to each other and the second cams 423 can move relative to each other. When the first stop 421 is in the unlock state, the first stop 421 is unlocked, and the second stop 421 is unlocked, so that the second stop 421 is unlocked.

[0055] This device can automatically withdraw the needle, avoiding the problem of improper operation during manual needle withdrawal, which may cause the needle to bend, break or damage the patient's tissue. At the same time, the piston is in the syringe 50, which avoids the backflow of the drug solution in the syringe 50. The residual drug solution cannot be effectively utilized, resulting in the actual amount of drug injected into the patient's body being less than expected, thereby reducing the anesthetic effect on the patient.

[0056] like Figure 4As shown, the control assembly 10 includes a handle 11, and a fixed rod 12 is fixedly connected to one side of the handle 11. The fixed rod 12 and the push plate 21, the limit plate 41 and the slide rod 32 are slidably connected. A driving assembly 13 is provided on one side of the handle 11, and the driving assembly 13 includes a motor 131 fixedly connected to one side of the handle 11, and the output end of the motor 131 is fixedly connected to a screw rod 132, and a movable plate 133 is threadedly connected to the screw rod 132. One side of the movable plate 133 is fixedly connected to a connecting rod 134, and the interior of the movable plate 133 is slidably connected to the surface of the fixed rod 12, and one end of the connecting rod 134 is fixedly connected to one side of the push plate 21.

[0057] Specifically, the user holds the handle 11 and then turns on the motor 131. The motor 131 drives the screw rod 132 to rotate, and the screw rod 132 drives the movable plate 133 to rotate. The movable plate 133 slides on the fixed rod 12 and drives the connecting rod 134 to move. The connecting rod 134 can push the pushing plate 21 to move, and the pushing plate 21 can drive the pushing frame 22 to move.

[0058] Working principle: the user holds the handle 11 and then turns on the motor 131. The motor 131 drives the screw rod 132 to rotate, and the screw rod 132 drives the movable plate 133 to rotate. The movable plate 133 slides on the fixed rod 12 and drives the connecting rod 134 to move. The connecting rod 134 drives the push plate 21 to move, and the push plate 21 drives the push frame 22 to move.

[0059] When in use, the syringe barrel portion of the syringe 50 is placed inside the clamping block 31, and one end of the piston is placed inside the clamping plate 222. After placement is completed, the limit plate 41 is adjusted to slide on the fixing rod 12 and the limit plate 41 is fixed by the bolt 45 to adjust the required needle insertion length. Then, when it is necessary to control the needle insertion operation, the push frame 22 can be driven to slide, and the push frame 22 drives the slide groove 23 to slide synchronously. In the initial state, the limit rod 33 is in the first limit section 231 of the limit groove, and then the push frame 22 is driven to slide. 22 slides toward one side of the clamping block 31, the pushing frame 22 drives the slide 23 to slide synchronously, the slide 23 pushes the limiting rod 33 to slide synchronously through the first limiting section 231, the limiting rod 33 drives the slide rod 32 to slide inside the fixed rod 12, the slide rod 32 drives the syringe 50 inside the clamping block 31 to slide synchronously, and the syringe 50 drives the needle to move. When the first limiting section 231 pushes the limiting rod 33 to slide to the limiting plate 41, the limiting plate 41 limits the limiting rod 33, and the required needle insertion length is completed at this time;

[0060] When the injection operation is required, the pushing frame 22 drives the limiting rod 33 to move to the limiting plate 41, the protrusion 44 on the limiting plate 41 contacts the inclined edge of the pushing frame 22, and the protrusion 44 squeezes the inclined edge of the pushing frame 22, causing the pushing frame 22 to slide toward one side of the clamping plate 222. At this time, the limiting rod 33 slides from the first limiting section 231 to the sliding section 232, and then the protrusion 44 squeezes the pushing frame 22, and the pushing frame 22 continues to slide, and the pushing frame 22 drives the sliding section 232 of the slide groove 23 to slide synchronously. At this time, the clamping plate 222 drives the piston of the syringe 50 to move toward the inside of the syringe 50, and the piston discharges the liquid inside the syringe 50, thereby completing the liquid injection operation;

[0061] When the push frame 22 drives the projection 221 to move to the position of the projection 44, the projection 44 presses the projection 221, so that the projection 221 drives the push frame 22 to slide toward the clamping plate 222 again. At this time, the limit rod 33 is released from the sliding section 232 and the second rotation plate 422 is engaged with the one end of the limit rod 33. The row section 232 slides to the second limit section 233, and the upper surface of the pushing frame 22 is away from the first rotating plate 421, so that the first rotating plate 421 is reset by the torsion spring 43, and the first rotating plate 421 drives the second rotating plate 422 to rotate and release the limit on the limit rod 33, and then the pushing frame 22 is reset, so that the protrusion 221 is away from the protrusion 44. At this time, the pushing frame 22 is reset by the spring 24 and squeezes the first rotating plate 421. The first rotating plate 421 is reset to be tilted inward and is limited by the protrusion 44. Therefore, the vertical squeezing force of the pushing frame 22 on the first rotating plate 421 will only make the first rotating plate 421 move toward the protrusion 44. Therefore, the first rotating plate 421 limits the pushing frame 22, so that the pushing plate 21 maintains the second limit section 233 to drive the limit rod 33 to reset, which can ensure that the piston is in the syringe 50 and will not reset, driving the syringe 50 to withdraw the needle.

Those skilled in the art should understand that the present invention is not limited to the foregoing embodiments. The foregoing embodiments and descriptions are merely illustrative of the principles of the present invention.
