Anti-splashing device based on liver interventional therapy

Abstract

The invention provides an anti-splashing device based on liver interventional therapy, and the device comprises a limiting plate which sleeves a puncture needle; the limiting assemblies are arranged at the top of the limiting plate, and the limiting plate is fixedly erected on the puncture needle; the at least one group of guide screw rods are fixedly arranged at the bottom of the limiting plate; the fixing plate penetrates through and is fixed with the guide screw rod; the movable plate is positioned below the fixed plate, penetrates through the guide screw rod and is in sliding fit with the guide screw rod; the threaded sleeve is in threaded fit with the guide screw and abuts against the bottom of the movable plate; the blowout prevention cover is fixed with the bottom of the movable plate; a plurality of connecting rod assemblies; each group of connecting rod assembly comprises a rotating rod, two ends of which are rotatably matched with the bottom of the fixed plate and the blowout prevention cover respectively; the sliding sleeve is slidably arranged on a rod body of the rotating rod; and one end of the connecting rod is rotationally connected with the top of the movable plate and the other end is rotationally connected with the outer side of the sliding sleeve. According to the device, blowout prevention covers with different areas can be erected according to requirements, and adjustment and disassembly are convenient during an operation.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a splash prevention device for interventional therapy based on the liver. Background technique [0002] Hepatic interventional therapy is a minimally invasive treatment method that treats local lesions under the guidance and instructions of medical imaging equipment. Usually, precision instruments such as special guide wires or catheters are introduced into the human body to diagnose and locally treat some liver diseases. Interventional therapy has the characteristics of no surgery, small trauma, quick recovery and good effect. [0003] However, blood spatter often occurs during liver interventional therapy, especially during arterial intubation. If blood spatter occurs, it greatly affects the operating line of sight and contaminates surgical tools and equipment. The structure of the existing anti-splash equipment is fixed. Although it has the function of sh...

Problems solved by technology

[0003] However, during liver interventional treatment, blood spatter often occurs, especially during arterial intubation. If blood spatter occurs, it will greatly affect the operation line of sight and contaminate surgical tools and equipment.

The structure of the existing anti-splash equipment is fixed. Although it has the function of shielding, it also greatly affects the line of sight of the follow-up operation. Therefore, this application proposes a new anti-splash device for interventional therapy based on the liver.
