Neurosurgery aspirator with electrocoagulation function

Abstract

The neurosurgical aspirator with the electrocoagulation function structurally comprises a grip, a conveying pipe, a negative pressure pump, an extension suction pipe and a drainage mechanism, the grip is connected to the conveying pipe, a telescopic conveying pipe is matched with the extension suction pipe in an electrical connection mode through the negative pressure pump, the drainage mechanism is arranged on the extension suction pipe, and the drainage mechanism is arranged on the extension suction pipe. A guiding device and a pressing structure are arranged in the power assisting body, and the guiding device and the pressing structure are matched on the partition plate, so that when the opening and closing pipe is filled and squeezed and wraps the guiding plug along the direction, the connecting grabhook is squeezed, and the locking knot stably abuts against the connecting grabhook upwards along the partition plate with the help of the pressing structure; the partition board swings downwards and leans against the guide device, the clamping block is further controlled to clamp the guide plug, the guide plug is prevented from changing the size and retracting into the opening and closing tube, a corresponding flow guide channel is provided for blood, and efficient implementation of the electrocoagulation function of the equipment is ensured.

Description

technical field [0001] The invention relates to the technical field of suction devices, in particular to a neurosurgical suction device with electrocoagulation function. Background technique [0002] In neurosurgery, when bleeding is encountered in deep surgery, bipolar coagulator is often used to stop bleeding when the amount is small. When the bleeding is reduced or the bleeding is basically stopped, electrocoagulation will be given to stop the bleeding. Under normal circumstances, the existing neurosurgical suction devices with electrocoagulation function generally use umbrella guidance. The plug maintains the blood circulation gap between the connecting gripper and the opening and closing tube, provides a corresponding diversion channel for the blood, and then realizes the purpose of regulating the flow and speed of the blood attracted by the suction cavity, so as to prevent the blood from being pumped out too quickly at one time. , it will cause secondary damage to the...

Problems solved by technology

[0002] In neurosurgery, when deep surgery encounters bleeding, a bipolar coagulator is often used to stop the bleeding when the amount is small. If the amount of bleeding is large, the general method is to first use the suction device to suck up the blood and find out the bleeding. Use cotton pads or gauze balls to stop the bleeding, and then give electrocoagulation to stop the bleeding when the bleeding is reduced or the bleeding is basically stopped. The existing neurosurgical aspirators with electrocoagulation function generally use an umbrella-shaped guide The plug maintains the blood circulation gap with the opening and closing tube by means of the connecting claws, and provides a corresponding diversion channel for the blood, thereby achieving the purpose of regulating the flow and speed of the blood attracted by the suction cavity, so as to prevent the blood from being drawn out too quickly at one time , will cause secondary damage to the affected area, and damage the electrocoagulation and hemostasis effect of the device on the affected area. When the blood in the suction chamber is drawn from the opening and closing tube to the guide plug, it will fill up the opening and closing tube and change its internal The size of the pressure makes the opening and closing tube wrap and bite on the umbrella-shaped structure of the guide plug through the connecting claws, so that the guide plug is squeezed between them to retract into the lantern-shaped opening and closing in the way of retracting the umbrella. In the tube, the blood circulation gap between the guide plug and the opening and closing tube is enlarged, the blood flow and speed attracted by the suction cavity are increased, the effect of protecting the affected area is lost, and the electrocoagulation function of the device on the affected area is also affected.
