Description
Technical field
This application involves laser therapeutic apparantus field, a kind of specific length switchable fiber coupling dual laser and swash
Photo-therapeutic instrument, for the treatment and hemostasis of soft tissue disease, the especially treatment of benign prostatic hyperplasis.
Background technique
Laser technology is rapidly developed in the application of medical field in recent years, and in soft tissue field, laser will substitute electricity quickly
It is cut to the goldstandard for the treatment of.The features such as laser bleeding is few, the risk of no trauma surface infestation, and no closed pore reacts allows laser soft tissue hand
Art is gradually won in competition.
The high power laser light of wavelength 2um, such as the Ho:YAG Bladder stone of 100W and the Tm:YAG laser of 120W are in prostate
Application in hyperplasia resection operation also has certain competitiveness.It is mainly absorbed by water in the tissue, and absorptivity height leads to group
It knits and gos deep into depth as shallow, it is poor to stop blooding.Cutting tissue effect is very strong, must be close to function of organization but solidify and stop blooding poor, optical fiber
Feature leads to difficult grasp etc. of performing the operation.The near infrared light of wavelength 980nm-1470nm or so, tissue go deep into 7-10mm of depth or so,
Be conducive to stop blooding.Notification number: the patent of 102090926 B of CN is cut using the combination of multi-wavelength with the wavelength of 2um
It cuts, is stopped blooding with 1470nm wavelength.The technology is complicated, realizes that difficulty is big, system bulk is difficult to safeguard greatly, is unfavorable for new technology
Popularization.
Green laser obtains a large amount of practice for soft tissue gasification cutting in clinic, sufficiently proves it safely and effectively, phase
Than in former generation " goldstandard " " transurethral prostatectomy " TURP, side effect is almost without being expected to become and replace TURP's
" goldstandard " of new generation.Different from the light of other wavelength, green laser is in human body mainly by hemoglobin absorption, in the water of human body
It can be transmitted at a distance under environment, tissue is directly gasificated into powder and is gone out by water, not need to carry out bulk tissue crushing again.
These unique advantages cause this wavelength of green laser necessarily to become the optimal selection that soft tissue disease is treated.But due to not having
Dissection cannot take pathology, and for big blood vessel and venous sinus bleeding also more difficult hemostasis, therefore twin wavelength laser output becomes green and swashs
The finer selection that light operation is promoted.
The patent of patent No. US 20180078310A1, the green laser of 532nm for describing a kind of power 20W add 40W's
The combination of 980nm near-infrared laser.The power of two kinds of wavelength of combination is all relatively low, and is that two kinds of lasers are closed by optical fiber
The mode of beam, which is transferred into, treats operation optical fiber, system complex, and stability is poor, it is difficult to safeguard.
Therefore, it is necessary to a kind of structure is simple, the high dual-wavelength laser therapeutic equipment of stability can switch output high-power
The green laser of 532nm and the near-infrared laser of 1064nm.532nm laser is used for for soft tissue gasification excision, 1064nm laser
The hemostasis of Soft tissue cutting, big blood vessel and venous sinus is required with meeting operation, becomes the better solution of operation on soft tissue.
