[0021] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.
[0022] Reference Figure 1-4 , the utility model embodiment of an anti-damage cervical auxiliary drug delivery device, which includes a drug delivery tube 5, a piston head 3 is provided inside the drug delivery tube 5, a connecting rod 2 is fixedly connected to the piston head 3, a control block 1 is fixedly connected to the connecting rod 2, and the end of the drug delivery tube 5 close to the control block 1 is fixedly connected to a blocking block 4, the shape of the blocking block 4 is a trumpet shape, and the end of the drug delivery tube 5 away from the control block 1 is fixedly connected to a protective head 9, the front of the protective head 9 gradually increases in longitudinal section from front to back, and the rear of the protective head 9 is evenly provided with drug outlet holes 7, the number of drug outlet holes 7 is at least eight, and a dispersing member 10 is provided in the drug outlet hole 7, the front of the protective head 9 is provided with a first arc portion 8, and the rear of the protective head 9 is provided with a second arc portion 6, the dispersing member 10 includes a connecting disk 1001 fixedly installed inside the drug outlet hole 7, and the connecting disk 1001 is provided with a second arc portion 6.
