Description
Technical field
The invention belongs to technical field of medical instruments, especially a kind of nerve endoscope camera lens flusher
Background technology
At present, under nerve endoscope, in the operation of per nasal sella region, must clean to guarantee clear picture camera lens at any time.Present way is to take over the road by the assistant with large syringe and constantly carry out the pulsed flushing.The method need push hard syringe piston when having following shortcoming: a, water spray, and pumpback immediately influences image, so very effort once after finishing to guarantee camera lens not filled by water droplet; B, repeatedly promote, pumpback causes air inlet in the syringe later on easily, and then influence operation is so often operation again behind the air-out can delay many times; C, need two syringes to use in turn, do not interrupt to guarantee flushing, this just needs constantly to pull down in the art standby syringe and draws water; D, two syringes are connected in the threeway, and volume is bigger, takies the apparatus disk space; 5, necessary bimanualness often needs assistant's specialized operations, is a kind of waste of manpower.
Summary of the invention
The objective of the invention is to design a kind of simple in structure, easy to use, save the gun type flushing device with automatic water inlet for neuroendoscope lens of muscle power.The object of the present invention is achieved like this: main body is the proficiency gun-type syringe, include syringe, the small of the stock, butt and trigger, the intravital piston of syringe cavity rear portion is connected with an end of extension spring, the other end of extension spring is fixedly on the syringe butt, connect trigger with the end of piston rod, the trigger axle is installed on the butt, the front end of syringe is provided with threeway, one end of threeway is communicated with in one with syringe, the water inlet of threeway connects saline bottle through water inlet pipe, and the outlet of threeway connects irrigating canula through outlet pipe.Be equipped with check valve in the water inlet of threeway and the outlet.Nerve endoscope is located in the irrigating canula.
Advantage of the present invention is easy to operate, and one hand is operated at once, does not need special assistant's operation, only needs instrument nurse to take into account and gets final product; Automatically pumpback is provided with extension spring in the syringe, resilience automatically, and the pulling piston is replied, automatically water inlet; Volume is little, does not take original limited apparatus disk space and saves manpower.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Among the figure, 1, syringe, 2, the small of the stock, 3, butt, 4, trigger, 5, piston, 6, extension spring, 7, piston rod, 8, trigger axle, 9, threeway, 10, water inlet, 11, water inlet pipe, 12, saline bottle, 13, outlet, 14, outlet pipe, 15, irrigating canula, 16, the water inlet check valve, 17, outlet check valve, 18, nerve endoscope, 19, the nerve endoscope camera lens.
The specific embodiment
With reference to accompanying drawing, this nerve endoscope camera lens flusher main body is the proficiency gun-type syringe, include syringe 1, the small of the stock 2, butt 3 and trigger 4, intravital piston 5 rear portions, syringe 1 chamber are connected with an end of extension spring 6, the other end of extension spring 6 is fixed on the butt 3, the end of piston rod 7 connects trigger 4, trigger axle 8 is installed on the butt 3, the front end of syringe 1 is provided with threeway 9, one end of threeway 9 is communicated with in one with syringe 1, the water inlet 10 of threeway 9 connects saline bottle 12 through water inlet pipe 11, and the outlet 13 of threeway 9 connects irrigating canula 15 through outlet pipe 14, and nerve endoscope 18 is located in the irrigating canula 15.The water inlet 10 of threeway 9 is provided with water inlet check valve 16, and the outlet 13 of threeway 9 is provided with outlet check valve 17.。
Using method of the present invention: before the use, earlier syringe 1 intracavity is filled with saline, when needing flushing, pull trigger 4 with hands, thereby promote piston 5 forward, under pressure, the outlet check valve 17 of threeway 9 is opened, the water inlet check valve 16 of threeway 9 is closed, and the current direction outlet pipe 14 in the syringe 1 arrives nerve endoscope camera lens 19 by irrigating canula 15.Unclamp trigger 4, piston 5 pumpback under the pulling force of extension spring 6, the outlet check valve 17 of threeway 9 this moment is closed, 16 openings of the water inlet check valve of threeway 9, water enters syringe 1 intracavity.Prepare the flushing of next time.
