Remote-controlled liquid embolism material precise injection device

Abstract

The present invention relates to the technical field of medical devices and particularly discloses a remote-controlled liquid embolism material precise injection device. The device comprises an injection workbench and a remote switch controller, and a support frame is arranged on a surface of the injection workbench; a main switch, a power supply, a wireless signal receiver, a remote switch, a motor, a lead screw, a lead screw nut and a lead screw nut seat are arranged in a box body of the injection workbench, a workbench push rod is fixedly arranged on an upper surface of the lead screw nut seat, and the push rod extends out of a push hole; and the remote switch controller comprises a switch controller body, a battery and a wireless signal transmitter, the battery is electrically connected with the wireless signal transmitter, and the wireless signal transmitter is connected with the wireless signal receiver through a wireless signal. The remote-controlled liquid embolism material precise injection device can accurately control injection dosage of a liquid embolism material in operation processes, and reduces time of exposing medical staff to an X-ray environment when the liquid embolism material is injected in interventional operations of cerebral arteriovenous malformation, etc. by utilizing wireless control.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a remote-controllable precision injection device for liquid embolism material. Background technique [0002] Cerebral vascular malformations or multiple vascular diseases represented by cerebrovascular malformations are common clinical diseases and usually require interventional therapy. Interventional therapy is a treatment method in which medical personnel deliver embolic materials to the diseased site through various catheters under the guidance of X-rays to complete the blockage of diseased blood vessels. The specific method is: puncture the arterial sheath through the femoral artery, and in the case of a definite diagnosis by cerebral angiography, insert a catheter through the arterial sheath to the carotid artery, and then insert a microcatheter through the catheter, and deliver the tip of the microcatheter to the carotid artery. Within the arteries feeding the...

Problems solved by technology

The prior art has the following disadvantages: when injecting liquid embolic materials, the doctor needs to perform the injection operation in the interventional catheterization room, the injection process lasts for a long time, and there is X-ray radiation in the interventional catheterization room, and medical personnel have to be exposed to X-rays for a long time, which is harmful to the human body. the damage is very large

When injecting liquid embolic material, it is necessary to decide whether to continue the injection or suspend the injection at any time according to the movement of the embolic material inside the deformity or the reflux situation. When the suspension is suspended, wait for a few seconds before injecting again. If the embolic material is not satisfactory, it is still suspended Inject, if satisfied, continue to inject until the course is not satisfactory; throughout the operation, this iterative process may be repeated hundreds of times

However, the existing micro-injection pump cannot be controlled remotely, and the injection cannot be repeatedly suspended at any time
