Abstract
The utility model provides a coronary atherosclerosis patch remove device, includes medical flexible fiber conduit, its technical essential in: medical flexible fiber conduit front end is provided with work portion, terminal connection control handle, work portion including cold light source, miniature camera and front end flexible patch shovel, the cold light source pass through the circuit be connected with the power miniature camera pass through the data line be connected with the display screen the patch shovel is connected with brake valve lever through the control cord. The utility model discloses the operation that utilizes this device belongs to the operation of intervention nature, and under the wound to the patient, the right disease of operation is broadened, does not receive the restriction of age and nutrition condition, putting into because of internal no support, not leading to the possibility of generating heat so there is the autogenous infection, no postoperative reforms the possibility of atherosclerosis patch at bracket rails, fall ill in early days the patient, treatment is better when stopping up the emergence, effective control patient's painful symptom, the emergence of prevention heart stalk, reduction patient's the death rate.
Description
Technical field
This utility model belongs to technical field of medical instruments, particularly a kind of Coronary Atherosclerotic Plaque withdrawing device.
Background technology
As everyone knows, atherosclerosis is type the most common and important in arteriosclerosis, and the inner membrance of the tremulous pulse that is characterized in getting involved has the calmness of lipoids, gathering of compound saccharide, then proliferation of fibrous tissue and calcific deposit, and has medial pathological changes.Primary disease mainly involves large-scale and medium-sized flesh elastic-type tremulous pulse, is common, often causes the serious consequence such as obliteration or tube wall Rupture haemorrhag with aorta, coronary artery and cerebral arteries.The atherosclerosis occurred on coronary artery is called coronary atherosclerosis.It is the atherosclerosis that the outer coronary artery of modal stenosis coronary artery disease, particularly flesh wall props up.Coronary artery proximal section why start well pulse atherosclerosis be due to it than all organ tremulous pulsies all near ventricle, thus bear maximum systolic pressure and clash into.Moreover coronary arterial vessel tree has most direction to change due to the shape of heart, therefore also bear larger blood flow shear stress.
Atherosclerosis is the basis causing a series of heart, cerebrovascular, wherein coronary heart disease becomes one of modern society's most important cause of disease causing old man's death especially, and main cause is exactly because Coronary Atherosclerotic Plaque blocking coronary artery causes myocardial ischemia and necrosis to cause death.
Existing treatment technology is mainly internal medicine and surgical interventional therapy.Medical treatment is Drug therapy mainly, takes effect slow, can only play the object of alleviation or protectiveness treatment; Surgical interventional therapy is based on the coronary stent technology on coronarography basis and coronary bypass technology.But these two kinds of technology all exist different shortcomings, coronary stent technology medium-height trestle comes off, the outer reproducibility lipid of support blocks, autogenous infection causes heating to happen occasionally; And coronary bypass technical operation wound is large, risk is high, there is operative indication.
Utility model content
For solving the problems of the technologies described above, the utility model proposes a kind of Coronary Atherosclerotic Plaque withdrawing device, it is on the basis of former coronary stent technology, utilizes increase illumination, taking-up and protection mechanism in cardiac catheter to complete operation and gets involved, removal sufferer.
The technical solution of the utility model is achieved in that
A kind of Coronary Atherosclerotic Plaque withdrawing device, comprise flexible medical fiber duct, described flexible medical fiber duct front end is provided with operate portions, end connection control handle, described operate portions includes the speckle shovel of cold light source, minisize pick-up head and bendable front end, and described cold light source is connected with power supply by circuit, described minisize pick-up head is connected with display screen by data wire, described speckle shovel is connected with joystick by control cord.
As further technical scheme, described operate portions also includes to connect with joystick and prevents the speckle backward distal displacement that comes off from occurring the umbrella speckle detent mechanism of far-end secondary thromboembolism.
As further technical scheme, described flexible medical fiber duct inwall is provided with two parallel next doors, speckle shovel is set in the cavity between two next doors, in a cavity between next door and flexible medical fiber duct inwall, umbrella speckle detent mechanism is set, in another cavity between next door and flexible medical fiber duct inwall, is provided with cold light source and minisize pick-up head.
As further technical scheme, the umbrella cover of described umbrella speckle detent mechanism is titanium network structure.
The beneficial effects of the utility model are:
1, utilize the operation of this device to belong to Invasive procedures, under the wound of patient, the suitable disease of operation is relaxed, and is not subject to the restriction of age and nutriture;
2, because inserting without support in body, so cause heating possibility without autogenous infection, without the postoperative possibility again forming atherosclerotic plaque at rack inner wall;
3, early stage morbidity, block therapeutic effect when occurring better, effectively control the pain symptom of patient, the generation of prevention heart infarction, the mortality rate of reduction patient.
