Detailed Description

The technical solution of the present patent will be described in further detail with reference to the following embodiments.

Referring to fig. 1-2, a cannula micro-needle automatic skin grafting device includes

The machine body 7, the liquid crystal operation interface 8 and the power switch 4 have the following functions:

function 1: count zero clearing

Function 2: negative pressure default-23 KPa

Function 3: positive pressure default (0.25 MPa, upper limit 0.22MPa, lower limit 0.18 MPa)

Each about the skin grafting cell-phone on organism 7, its inner structure is the same:

the skin grafting mobile phone shell part is composed of materials which can bear high temperature and high pressure above the tolerance, an air pipe A0, a tail part A1, a main spring push column A2, a spring A3, a middle shell A4, a front end shell A6 casing outer needle A7 of a vent hole A5 and a casing inner needle A8, and the internal structure of the skin grafting mobile phone shell part is shown in the attached drawing.

The method comprises the following operation steps:

the inner structure of the left and right skin grafting mobile phones is assembled firstly, namely: the connection of a vent pipe A0, a tail part A1, a spring main push column A2, a spring A3, a middle shell A4, a vent hole A5 and a front end shell A6 casing outer needle A7 and a casing inner needle A8 part completes the connection of the internal parts;
