Description
Technical field
The invention belongs to the field of medical instrument technology, more particularly to a kind of laser aiming devices for being operated under laparoscope
Tool.
Background technology
When superlaser affected tissues, the light wave for carrying high energy is delivered to tissue surface, tissue resorption laser energy is main
Generate two effects：
1. photothermal acts on：Central area energy is concentrated and is gasified, and all the components in tissue all can be straight by solid
It connects and becomes gas, with prodigious rate projects and leaves a pitfall region, this region surface layer constantly carbonizes rapidly, that is, organizes hair-weaving
Raw dry necrosis, blood and plasma protein solidification, form brownish black carbide.Although Near tissue receiving is transmitted to therewith
There is protein thermocoagulation in high fever, its visible lower higher depth of histological observation occurs self-dissolving and decomposes, then depths is inflammation district, this
Kind thermocoagulation necrosis is uniform, and the cell of solidification zone is escaped by luck almost without one, and thermotropic tissue coagulation effect can stop blooding, but carbon
Compound is discharged with gasification into environment, forms toxic smog.In addition, thermotropic vaporization phenomenon is also shown, due in tissue
Containing a large amount of water, boil at 100 degree.When tissue receives energy when more than 100 degrees Celsius, the water of intraor extracellular can be anxious
Play vaporization is broken through cell and tissue and is released, and takes away some cell fragments, and before tissue is not carbonized also, naked eyes are visible white
Color smog.
2. photic pressure action：Laser instantaneous power density is larger, laser can by little energy (several J to tens J),
Space (milliradian) high concentration of (10-9-10-12 seconds) in a short period of time, very little is got up, and high pressure effect is generated.Swash
There are two types of the pressure actions that light irradiation generates：One is the radiation pressures of laser itself to be formed by pressure, referred to as a pressure.
Although the radiation pressure of laser itself is very faint, energy is quite concentrated, and pressure is considerable.Another laser action
After biological tissue, secondary secondary pressure can be generated, this is because light laser acts in biological tissue, in addition to optical pressure, also
There is steam flow recoil to hit, interior evaporation pressure thermally expands, caused by the factors such as excess sound pressure and electrostriction pressure.
Clinically, it is applied for a long time in surgery using the Pressure effects of laser, in early days such as the anterior chamber angle of the glaucoma of ophthalmology

If energy is not evacuated (contact tissue simultaneously be absorbed by tissue) in time, or infusion energy does not reduce, then optical fiber head easily heat waste is very
To melting, optical fiber burning occurs.There is experiment display using 400 μm of optical fiber in CO2It carries out operating under laparoscope under pneumoperitoneum environment, put down
Optical fiber also incendivity when equal power is higher than 30W.
Tissue is cut using superlaser under the water environment of cycle, can avoid above-mentioned drawback：Carbonization is not generated
I.e. non smoke generates；It is heated to reduce surrounding tissue conduction；Fiber optic tip waste heat is reduced, optical fiber is nonflammable.Therefore, Digestive
System, urinary system carry out laser operations under water environment.Gastrovascular cavity, urinary tract cavity space are limited, the physiology salt of top-off cycle
Water is easier, however to some organ of abdominal cavity laser operations to be carried out, entire abdominal cavity is absorbed in the water environment of cycle not existing
It is real.Therefore the laser aiming instrument that research and development one are suitable for operating under laparoscope, and low-temperature normal saline can be exported from optical fiber surrounding,
Achieve the effect that " optical fiber-tissue target area " does not play the same tune on different musical instruments in cycle water environment.
