Description
Technical field
The invention belongs to surgical operating instrument field, more particularly to a kind of jet cutting field.
Background technology
Water knife is the equipment that cold conditions cutting is carried out using high-pressure water jet, industrial circle is applied at first, for cutting
Sheet metal, ore etc., just really it is used for clinical operation until nineteen ninety.The pressure of medical water jet is far below industry water knife, but
Its operation principle is similar with industry water knife, i.e., is pumped out sterile saline using high-pressure pump, and operation handle is reached by conduit,
Sprayed by the fine nozzle on handle, produce partial high pressure to cut tissue.
The characteristics of maximum of medical water jet, is, to the progress selectivity cutting of the institutional framework of varying strength and toughness and finely
Separation so that the advantages of particular organization is farthest protected, and is had and got a clear view, and amount of bleeding is few, simultaneously because
Water knife does not produce heat energy, and will not causing other, such as electric knife, laser, ultrasound knife operating theater instruments produce damage to surrounding tissue
Fire damage.In recent years, medical water jet relies on its unique advantage, is widely used in liver and gall surgical department, neurosurgery, rectum in the world
In the clinical trainings such as surgery, ear-nose-throat department Head and neck tumour, and in laparoscopic surgery.
German ERBE discloses a kind of medical water jet (US8251679B2 and US2014/0079580A1), its structure
Complexity, pressure precision is low, and production cost and medical disposable material cost are high.Academy of Military Medicine, PLA's sanitary packing
Standby research institute have developed domestic first generation model machine for 2009, and the model machine employs a variety of spray guns using hydraulic pump as pressure source,
Realize water knife tissue is cut in high pressure, low pressure when the surface of a wound is cleaned, but model machine volume is big, heavier-weight；Hydraulic pressure
Pipeline is more, and valve body is more, is unfavorable for sealing；Water knife spray gun use for medical cleaning spray gun, for high pressure tissue cut timeliness
Fruit is undesirable.Second generation model machine is have developed within 2010 again, the development of the model machine realizes miniaturization, the lightweight of water knife, and
Employ new medical pump, tissue is cut when meeting high pressure, low pressure when requirement to surface of a wound cleaning, but its is medical
Pump employs the reciprocating plunger pump by lead screw transmission, when two plungers commutate, can produce pressure oscillation, and the design of Tuo He mechanisms is not
Rationally, it is impossible to meet the requirement of the disposable of medical pump, sterileization.
The operation water knife that design research and development are compact-sized, simple to operate, cost is cheap reduces patient for promoting medical advance
Medical treatment cost has positive effect.
The content of the invention
