Abstract

An electric injection device, in particular to a constant-speed and quantity-controlled fat injection device which is mainly used for autologous fat transplantation. The electric injection device can inject according to the operation requirement, the dosage is controllable, the position is accurate, the injection is uniform, the operation is controllable, the operation effect can be improved, the operation time can be shortened, the labor intensity of doctors is reduced, the medical risk is reduced, and the electric injection device is simple, convenient, safe and effective.

Description

Electric injection device
Technical Field
The invention relates to an electric injection device, in particular to a constant-speed quantity-control fat injection device.
Background
The autologous fat transplantation operation is a new generation of human body modeling operation after the prosthesis implantation operation, and has the characteristics of no rejection in implantation, natural hand feeling, shapeability and no psychological shadow generation caused by foreign body implantation of patients. The autologous fat adopts an injection implantation mode, the operation process technology has very strong tolerance to an operator, the selection of the capacity of an injector, the labor intensity of a large-dose injection operator and the control of the injection speed are realized, and particularly, the accurate injection technology control of micro-injection and the patient pain caused by the difficulty in survival of fat due to the accumulation implantation are always the bottleneck of industry development and the short board meeting the requirements of customers.
Disclosure of Invention
The invention relates to an electric injection device, in particular to a constant-speed, quantity-control and accurate fat injection device, aiming at providing a constant-speed, quantity-control and accurate fat injection device, solving the problem that the poor medical events of non-blood supply and oxygen supply and envelope formation caused by uneven manual injection force of surgeons are caused.
The purpose of the invention is realized by the following ways: the injector clamping frame (2) is connected with the lead screw group (3) and then installed in the handle (1), the control switch (4) is installed on the handle (1), the motor (5) is connected with the speed regulating switch group (6), the display screen (7), the battery (8) and the circuit board (9) and then placed in the brake body (10), and the brake body (10) is inserted into the handle (1). A battery (8) is formed and supplies power, a circuit board (9) provides a program command to the motor (5), and the motor (5) applies work to the lead screw group (3) through the control switch (4) to move the injector on the injector clamping frame (2) back and forth to complete the fat injection operation.
The invention has the advantages that: 1. the injection amount is accurate and adjustable, the injection speed is controllable, the injection speed can be selected according to the transplanting amount, the battery power supply is safe and effective, the programmed operation reduces the labor intensity of doctors, the stacking implantation is effectively avoided, and the pain of patients and medical disputes are reduced; 2. the operation is convenient, different gears are selected to obtain different pushing speeds, and the adjustment is random; 3. the product has high safety, the low-voltage battery supplies power, and the handle part can be sterilized at high temperature and high pressure for repeated use; 4. simple structure and low cost.
Drawings
FIG. 1 is a schematic cross-sectional view of the present invention.
The invention is explained in further detail below with reference to the drawing.
Detailed Description
As shown in figure 1, the invention consists of a handle (1), an injector clamping frame (2), a lead screw group (3), a control switch (4), a motor (5), a speed regulation switch group (6), a display screen (7), a battery (8), a circuit board (9) and a brake body (10); the injector clamping frame (2) is connected with the lead screw group (3) and then installed in the handle (1), the control switch (4) is installed on the handle (1), the motor (5) is connected with the speed regulation switch group (6), the display screen (7), the battery (8) and the circuit board (9) and then placed in the brake body (10), and the brake body (10) is inserted into the handle (1) to form the injector.
