Abstract
The invention relates to a laser work handle applied in a laparoscopic surgery. The laser work handle comprises a work channel and a handle body. A side hole is formed in the front end of the work channel; and a water entrance channel and a fiber channel are arranged inside the work channel and the water entrance channel and the side hole are connected. A fiber interface and a water inlet pipe interface are formed in the handle body; a water sealing cap is arranged at the fiber interface; and a switch knob is arranged at the water inlet pipe interface. The laser work handle has the following advantages: the provided handle can be held by the operator easily during operation, thereby improving stability of the laser fiber operation; with the water inlet pipe interface at the handle, the flow can be adjusted by the switch knob at operation and the heat generated by the laser can be absorbed, so that the normal tissue adjacent to the lesion tissue can be protected from being damaged by the laser and thus accuracy and safety of the operative treatment can be improved.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, specifically, is the laser work handle used in a kind of laparoscopic surgery.
Background technology
At present, laser is more and more widely used in clinical operation treatment, by a long laser fiber, laser being imported to human body needs the position of diagnosis and treatment to treat, because laser fiber is more elongated, doctor is in use difficult to hold, affect accuracy during operation technique, thus affect operation safety; The high temperature simultaneously produced in laser use procedure easily damages the contiguous normal tissue of pathological changes, and safety is that the use of laser in laparoscopic surgery is restricted.Current laser is mainly used in lower urinary tract operation, and the technology of the laser work handle coordinating cystoscope to use clinically is very ripe, but lacks the working handle that can use in laparoscopic surgery.
Chinese patent literature CN200420020225.5, discloses a kind of means for holding laser optical-fiber, and it by improving the position stability of laser surgery laser fiber in the tube chamber that fibre-optic catheter is placed in suction catheter, but can not protect normal structure not burnt.The laser work handle holding about facilitating patient, improve operation operability, improve the position stability of laser fiber, normal structure can be protected not to be damaged simultaneously, yet there are no report.
