Detailed Description

The invention will be further explained with reference to the following figures and examples:

as shown in fig. 1 and 2, the needle inserting device for internal medicine of chinese medical science disclosed in the present invention comprises a needle cylinder 12, the needle cylinder 12 has a cylindrical hollow cavity 122 along the axial direction, and the hollow cavity 122 penetrates the needle cylinder 12 from top to bottom. The upper end of the syringe 12 is connected with an upper end cover 11 through a screw thread, the lower end of the syringe 12 is connected with a lower end cover 13 through a screw thread, and both the upper end cover 11 and the lower end cover 13 are used for sealing the hollow cavity 122. An ejector pin mechanism is also disposed within the hollow cavity 122 of the syringe 12. The ejector pin mechanism includes a pressing rod 21, a tension spring 22, a pressing head 23, and a spring plate 24 in the hollow cavity 122. The center of the upper end cover 11 is provided with a through hole along the axial direction, and the pressure lever 21 is connected with the upper end cover 11 in a sliding way through the through hole. The side wall of the pressure head 23 is in up-and-down sliding fit with the needle cylinder 12, and the lower end of the pressure rod 21 is fixedly connected with the pressure head 23. The tension spring 22 is sleeved on the pressure lever 21, the upper end of the tension spring 22 is fixedly clamped with the upper end cover 11, and the lower end of the tension spring 22 is welded and fixed with the pressure head 23. The center of the lower end cover 13 is provided with a guide hole 131 for the needle handle 6 to pass through along the axial direction, and the guide hole 131 is small at the upper part and large at the lower part.

In this embodiment, the number of the spring pieces 24 is two, and the two spring pieces 24 are symmetrically arranged in the hollow cavity 122. The upper end of the spring plate 24 is fixed to the cylinder 12. A protrusion 121 is formed on the sidewall of the hollow cavity 122 of the syringe 12 close to the lower end cap 13, a square groove for the spring plate 24 to pass through is formed on the protrusion 121, and the lower end of the spring plate 24 passes through the square groove from top to bottom, so that the lower end of the spring plate 24 is in sliding fit with the protrusion 121. As shown in fig. 1 and 2, the middle portion of the spring plate 24 is convexly curved toward the center of the cylinder 12, and at the same time, the middle portion of the spring plate 24 is formed with a concavely curved groove 241. The two arc-shaped grooves 241 of the two spring pieces 24 are respectively abutted with the needle handle 6 from the left and right directions, and under the elastic force of the two spring pieces 24, the needle handle 6 is firmly locked between the two spring pieces 24 as shown by the arrow in fig. 2. When the silver needle is not clamped, the middle parts of the two spring pieces 24 are contacted.

As shown in fig. 1, the needle cylinder 12 is also connected with a medical spring clamp 5 through a pull rope 4, and the structure of the medical spring clamp is similar to that of a book end. In use, the doctor can use the medical spring clamp 5 to clamp the silver needle. The medical spring clamp 5 in the scheme is a spring clamp made of medical plastics or medical silica gel materials, and belongs to the medical spring clamp 5 in the prior art. As shown in fig. 1 and 2, the lower portion of the pressing head 23 is provided with a conical head 231, the conical head 231 is coaxially arranged with the hollow cavity 122, and the conical head 231 is large at the upper part and small at the lower part. When the ram 23 moves downward, the tapered head 231 applies pressure to the two leaf springs 24 simultaneously, so that the two leaf springs 24 are separated from each other along the radial direction of the hollow cavity 122.

The working principle of the scheme is as follows:

when the acupuncture needle is used specifically, a doctor clamps the silver needle for acupuncture by using forceps or a clip, and the needle handle 6 is inserted between the two spring pieces 24 through the lower end cover 13, and the needle handle 6 is clamped and fixed by the arc-shaped grooves 241 of the two spring pieces 24. The doctor can acupuncture the patient by holding the cylinder 12. After the silver needle is inserted into the body of the patient, the doctor presses the pressing rod 21 with the thumb of the single hand holding the syringe 12, the pressing rod 21 pushes the pressing head 23 downwards, the conical head 231 of the pressing head 23 simultaneously presses the two spring strips 24 in the downward movement process, so that the two spring strips 24 are separated along the radial direction of the hollow cavity 122, the spring strips 24 are separated from the needle handle 6, and the acupuncture process is completed. The tension spring 22 prevents the pressure head 23 from sliding downward along the hollow cavity 122 under the action of gravity, and also urges the pressure rod 21 and the pressure head 23 to return upward for the next operation.

In the above implementation, the guiding hole 131 of the lower tube is used to limit the needle handle 6, and of course, this limitation only prevents the needle handle 6 from deviating by too large a deviation angle, and since the silver needle inserted into the skin of the patient does not deflect basically when the doctor conducts acupuncture on the patient, there is no need to precisely guide the needle handle 6. The guide hole 131 formed in the lower end cover 13 is small at the top and large at the bottom, and the design is favorable for the needle handle 6 to enter the needle cylinder 12. As shown in fig. 1, a pressing block is fixedly connected to the upper end of the pressing rod 21, and the pressing block 3 is located outside the syringe 12. The pressing block 3 can increase the contact area between the fingers of the doctor and the pressing rod 21, so that the pain of the fingers of the doctor caused by excessive pressing times can be avoided.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
