Another is that bone, especially cortical bone, is hard and difficult to access. Therefore, the technology needs to solve three problems, which are:
1. how to solve the problem of puncture pain.
2. How to solve the problem of pain generated when the medicine is diffused in tissues.
3. How to enter the bone tissue.
In order to solve the problem of pain generated during puncture, tissue surface anesthesia is firstly adopted at present, then manual slow puncture is carried out, the puncture range is ensured to be within the pre-anesthesia range as far as possible, the subsequent injection of the medicine can be manually carried out or mechanically and automatically administered, and the propelling speed of a needle head is ensured to be slower than the diffusion speed of the anesthetic as far as possible.
In order to solve the problem of pain caused by diffusion of the medicine in tissues, the medicine is slowly administered by pushing the medicine by hands or is slowly administered by mechanical control, so that the administration speed is as far as possible within the threshold range of the pain of a human body.
In order to solve the problem of entering bone tissue, the method adopted at present mainly comprises the steps of grinding the bone tissue, particularly cortical bone, by a drill and injecting the medicine by a needle, and the medicine is leaked and has poor effect because the aperture is not tightly sealed with the injection needle.
In a word, only bolus drugs realize automatic drug delivery at present, but cannot completely solve the pain problem, and no good method exists for entering bone tissues at present.
The invention realizes the automation of three actions of puncturing tissue, injecting medicine and entering bone tissue, replaces manual operation by machinery, couples the three actions according to parameters obtained by clinical experience, completes the painless and smooth process of entering the bone tissue of the medicine, and achieves the effects of painless injection and perfect anesthesia.
