Abstract
The utility model discloses laser surgical equipment used for treating urinary system diseases. The laser surgical equipment used for treating the urinary system diseases comprises a laser generator and an optical fiber which is connected with the laser generator, the laser generator generates green laser, and the tail end of the optical fiber makes direct contact with the surface of prostate tissue and conducts vaporization or cutting on the surface of the prostate tissue. According to the laser surgical equipment used for treating the urinary system diseases, the green laser not only keeps an original vaporization function, but also has a function of cutting a large block of tissue, the speed of a surgery and tissue cutting efficiency are greatly improved, and tissue samples can be kept after the surgery for inspection. The laser surgical equipment used for treating the urinary system diseases can further be connected with a laser hemostat, the laser hemostat is fixed at the tail end, which directly sends the green laser, of the optical fiber to convert the laser into heat energy, and therefore hemostasis becomes fast and easy. After the hemostasis is completed, the laser surgical equipment can enter a surgical state of tissue cutting as long as the front end of the optical fiber is cut off. Compared with an original optical fiber which sends the laser from sides, the laser surgical equipment used for treating the urinary system diseases can be repeatedly used after disinfection treatment, and therefore surgery cost and economical burden of a patient are reduced.
Description
Technical field
This utility model relates to medical apparatus and instruments, is specifically related to a kind of laser operation equipment that is used for the treatment of diseases of urinary system.
Background technology
The green laser gasification art of per urethra (PVP) is to be applied to a kind of important techniques means of clinical treatment benign prostate hyperplasia at present, its mirror surface by the laser fiber end with laser at a certain angle and distance be refracted to the prostata tissue surface with its gasification (so claiming side to go out green laser again), yet the several fatal weakness that this just special working method has brought PVP to be difficult to overcome: 1) gasification rate is slow, operating time is long, tissue residue is many, late relapse rate height.This is because fragment of tissue can stick on the mirror surface usually and form hot spot and then damage minute surface, cause output significantly to reduce 50-80%, secondly optical fiber speed of rotating, angle and and the distance of tissue all can influence gasification result, be difficult to remain on optimum state, and after the tissue on top layer is gasified, it is difficult that the tissue gasification of deep layer can become, owing to can only gasify and can not directly cut and organize, also caused cutting tissue efficient lower simultaneously; 2) owing to organize all to be fallen by gasification, postoperative does not have tissue specimen to inspect by ready samples, has lost the chance that detects accidental carcinoma of prostate; 3) not good for big blood vessel haemostatic effect.This is because big vascular flow pressure is big, because the laser-bounce minute surface can't directly be oppressed the blood vessel section and be caused forming effective tissue coagulation layer; 4) the operation cost is higher.Because the laser-bounce minute surface is easy to damage, generally finishes back optical fiber and all can't reuse, and once needing 2-3 root optical fiber at least in the operation, thereby increased the operation cost widely for the prostate of large volume in operation.
The PVP technology causes above-mentioned shortcoming to overcome, has limited it to a great extent in clinical extensive use owing to it adopts the laser fiber of side bright dipping to perform a surgical operation.
Summary of the invention
In order to overcome the shortcoming of side light-coming out optical fiber, the green laser fiber that this utility model is carried present use changes completely.The laser-bounce minute surface of at first having removed optical fiber connector makes laser directly penetrate from optical fiber connector, and laser no longer keeps certain distance and adopts the mode that directly contacts with tissue surface, and laser energy keeps constant and can not decay in operation process like this.
The technical solution of the utility model is: a kind of laser operation equipment that is used for the treatment of diseases of urinary system, comprise laser generator and the optical fiber that is connected with laser generator, described laser generator is green laser, and described optical fiber connector directly contacts and to gasifying with prostata tissue is surperficial.
Further improvement of the utility model comprises:
Described optical fiber is connected with the laser hemostasis device.
Described laser hemostasis device is the spheroid of being made by solid-state metallic material, offers blind hole on the described spheroid, has put optical fiber in the described blind hole.
Described laser hemostasis device is connected by heat-shrink tube with described optical fiber.
Described laser hemostasis device is made by rustless steel.
Also comprise the Handheld Division that is used for fixing optical fiber.
Described Handheld Division also is provided with endoscope.
Described laser hemostasis device is the spheroid of being made by solid-state metallic material, offers blind hole on the described spheroid, and extending at the blind hole correspondence position on the described spheroid has a connection tube, and the internal diameter of described connection tube is not less than fibre diameter.
Offer louvre on the described connection tube wall.
Offer two parallel cut surfaces on the described connection tube wall, described tangent plane is kept away connection tube and is formed two corresponding mutually otch, described notch depth is greater than the connection tube wall thickness, make to connect on the tube wall and cut out two louvres, the tube wall of described louvre correspondence can be used for exerting pressure and clamp the optical fiber that gos deep in the connection tube, is the optical fiber difficult drop-off.
This utility model makes green laser not only keep its original gasification function but also has had the function that bulk cuts and organizes, and the excision efficient of the speed of operation and tissue has had significantly raising than simple PVP, and postoperative can be retained the tissue specimen censorship.Secondly in order to solve original green laser shortcoming not good to the trunk haemostatic effect, we have designed the laser hemostasis device that is specifically designed to directly to go out green laser fiber, this laser hemostasis device can be firm be fixed in the end that directly goes out green laser fiber optical fiber, laser can be converted to heat energy, make the hemostasis of trunk become fast and simply, and when hemostatic closure, only need the optical fiber front end is cut off the surgical state that can enter cutting tissue once more.Because the thorough change of mode of operation, compare with original side light-coming out optical fiber and directly to go out green laser fiber through can repeated multiple times using after disinfecting, thereby reduced perform the operation cost and patient's financial burden widely.
Utilize directly to go out the surgical data comparison that green laser fiber has been implemented about 310 examples of transurethral prostatic resection and original side light-coming out optical fiber, this utility model has shown huge advantage, and concrete data are as follows:
