Abstract

The utility model is a super impulse CO2 laser microsurgery operation system, which is composed of a surgery microscope, a micromanipulator, and a super impulse CO2 laser, wherein, the light arm on the impulse laser is fixed by a locking bolt arranged through focus to be connected with the collimator of the micromanipulator; the fastening threads of a manipulator of the microscope adapter ring are fixed by the locking bolt of the adapter ring to be connected with the micromanipulator; the fastening threads of the microscope are connected with the objective lens of the microscope. The super impulse CO2 laser is combined with the surgery microscope through the laser to form a CO2 laser microsurgery system; guided by an indicating light, the super impulse laser beam passes through a deflecting mirror on the manipulator and reaches the surgery plane. The utility model can accurately conduct CO2 laser surgery and expand the using range of the super impulse CO2 laser.

Description

Super pulse CO 2Laser capture microdissection operation technique system

Technical field

This utility model discloses a kind of super pulse CO ₂Laser capture microdissection operation technique system is to existing C O ₂Laser therapeutic apparatus improves, and belongs to the laser medicine technical field of surgical instruments.

Background technology

At present, CO ₂Laser is applied to the history of clinical existing three more than ten years as operating theater instruments, its vaporization to tissue, cut, solidify, anastalsis, make CO ₂Laser surgery has insufficiency of blood, infects the characteristics that the time is short and wound healing is fast low, operation.

Because existing CO ₂The light beam conduction of laser therapy aparatus must realize CO by mechanical light-conducting arm ₂Laser surgery can only carried out human body surface or shallow table tract carries out, therefore, and CO ₂The scope of application of laser therapy aparatus has been subjected to very big restriction.

The utility model content

This utility model provides a kind of super pulse CO ₂Laser capture microdissection operation technique system can independently or by the chamber mirror carry out the laser capture microdissection operation, has overcome existing CO ₂Laser therapeutic apparatus is only applicable to the limitation of human body surface or shallow table tract operative treatment.

" the super pulse CO that this utility model relates to ₂Laser " be a kind of laser pulse output form, be characterized in that pulse width is narrower, peak power is high.The used super pulse CO of native system ₂The pulse width of laser machine is less than 1ms, and peak power is greater than 100W, on this basis by output control, the way of output such as can form continuously, repeat.Used laser instrument can be conventional stimulable type (glass tube sealing chamber), also can be the radio-frequency (RF) excited type.

Technical solution of the present utility model is as follows: utilize micro-manipulator, microscope adaptation ring with existing super pulse CO ₂Laser machine and operating microscope connect to form the super pulse CO of a cover ₂Laser surgery system, described micro-manipulator is a kind of device that can focus on and guide and handle laser, it comprises: pointing instrumentation, hot spot stick, manipulator handrail, wherein, light-conducting arm on the super pulse laser machine is connected with the pointing instrumentation of micro-manipulator, and the object lens of operating microscope are connected with micro-manipulator by the microscope adaptation ring.

Described microscope adaptation ring is the ring-type mechanical part that connects micromanipulator and microscope objective tube, be respectively equipped with manipulator binding thread and microscope binding thread in the upper and lower of adaptive ring body, the microscope adaptation ring can provide different specification size, can make the operating microscope of micro-manipulator and different model adaptive.

Super pulse CO ₂Laser capture microdissection surgery systems work process: super pulse laser beam under the pilot light guiding, arrives the operation plane by the deflecting mirror on the micro-manipulator.The patient is field of view under operating microscope, and can laser spot be adjusted in focal length be provided with on the default focal plane of device by the pointing instrumentation handle on the micro-manipulator; According to the requirement of operative approach, by focal length device is set hot spot is defocused/focus adjustment; The patient can pass through hot spot manipulator handle, and hot spot is moved and the alignment targets tissue in surgical field of view, so far, can start laser output and undergo surgery.

Good effect of the present invention is: will surpass pulse CO ₂The laser machine combines with operating microscope by micro-manipulator, forms the super pulse CO of a cover ₂The laser capture microdissection surgery systems can accurately be carried out CO at microscopically ₂Super pulse CO has been expanded in laser surgery ₂The laser machine scope of application.
