[0002] In recent years, diseases of the digestive, urinary, respiratory and other natural cavities have seriously endangered human health. The main treatment method is to use flexible endoscopes in combination with related surgical instruments for diagnosis and treatment. This treatment method has the characteristics of less trauma, less bleeding and low incidence of complications.

[0003] Endoscopic dissection (ESD) is often used in flexible endoscopy diagnosis and treatment. Submucosal injection is one of the key steps before ESD operation. This step requires injecting a specific liquid into the submucosal layer of the mucosal lesion, which can fully lift the lesion and achieve separation of the submucosal layer and the muscular layer, which is beneficial for ESD to completely remove the lesion without damaging the intrinsic muscular layer and reduce the occurrence of complications such as perforation and bleeding.

However, the submucosal injection of ESD requires a lot of injection force to complete, which greatly consumes the physical strength of medical staff, and the injection volume each time cannot be controlled, and the lifting effect is poor.

When the drive motor 210 drives the lead screw 221 to rotate, the nut 222 makes a linear motion along the axial direction of the lead screw 221, thereby driving the push rod assembly 230 to make a linear motion, thereby pushing the injection rod 110 to move in the syringe 120 to achieve injection. The speed of the injection rod 110 can be adjusted by adjusting the speed of the drive motor 210, thereby adjusting the injection speed, and then adjusting the injection dose.

[0061] The injection propulsion device disclosed in the embodiment of the utility model adopts the cooperation of the driving motor 210, the screw nut transmission assembly 220 and the push rod assembly 230, has a simple structure, is easy to implement, and is convenient to control.

[0062] like Figure 8 As shown, in some specific embodiments, the push rod assembly 230 includes a push rod 231 and a contact push plate 232, wherein the first end of the push rod 231 is fixed to the nut 222, specifically by a threaded connection or a clamping connection, or by a welding connection, or by other connection methods, and the contact push plate 232 is arranged at the second end of the push rod 231. Specifically, the cross-sectional area of ​​the contact push plate 232 is larger than the cross-sectional area of ​​the injection rod 110, so as to increase the contact area between the injection push plate 232 and the injection rod 110, thereby facilitating the pushing of the injection rod 110.

[0063] In other specific embodiments, Figure 8 As shown, the push rod assembly 230 further includes a second bearing seat 270 and a second bearing 271 disposed in the second bearing seat 270.

The syringe identification element 311, the zeroing button 312 and the push rod stroke detection element 313 are all electrically connected to the control cabinet 321. The syringe identification element 311 is used to identify whether the syringe 100 is installed on the syringe docking member 421. Specifically, a position sensor can be used. The specific setting position can be specifically selected according to actual needs. In some specific embodiments, such as Figure 3As shown, the syringe identification element 311 is arranged on the syringe docking member 421. The zeroing button 312 is arranged on the contact push plate 232.

When the contact push plate 232 contacts the injection rod 110, the zeroing button 312 is triggered, and the driving mechanism 200 stops running. The push rod stroke detection element 313 is used to detect the stroke of the push rod 231, so as to determine the liquid volume of the injection liquid in the syringe 120.

[0066] Before the injection is needed, the injection propulsion device is first checked, and the power button is pressed. The detection information of the detection component 310 is fed back to the display screen 322. If there is an abnormality, the abnormal information will be displayed on the display screen 322 and an alarm will be sounded. Then the doctor installs the syringe 100 filled with injection liquid on the syringe docking piece 421, and then presses the power button, the drive mechanism 200 starts, drives the contact push plate 231 to move, until the contact push plate 231 contacts the injection rod 110, triggers the zeroing button 312 to stop moving, and the detection information of the detection component 310 is fed back to the display screen 322. Then press the injection button, the drive mechanism 200 starts, pushes the injection rod 110 to move in the syringe 120, and performs the injection.
