Abstract

A stepless variable speed irrigation-suction system for endoscope operations includes an irrigation-suction conversion duct(2), a positive pressure adjuster(11), a negative pressure adjuster(22), a positive pressure bottle(9), a negative bottle(20), a positive pressure source, a negative pressure source and rubber ducts for connecting each components. The irrigation-suction conversion duct(2) is provided with an assembly structure of an inner duct(17) and an outer duct(3). An irrigation water interface(4) and a suction interface(18) are disposed at both sides of the outer duct(3). An opening is provided at the side wall of the inner duct(17). The opening(5) communicates respectively with the irrigation water interface(4) and the suction interface(18) by rotating a knob to realize the conversion between irrigation and suction. The front terminal of the outer duct(3) is a joint to connect diversified suction heads(1). The positive pressure or the negative pressure is adjusted by sliding a slide block of the positive adjuster or the negative adjuster so as to adjust the strength of irrigation or suction. Suction heads of different angles and diameters are replaced according to operation states.

Description

The intranasal videoendoscopic surgery washes attraction system with infinitely variable speeds

Technical field

This utility model relates to the medical apparatus and instruments that a kind of intranasal videoendoscopic surgery is used, and relates in particular to a kind of infinitely variable speeds flushing attraction system.

Background technology

Since eighties of last century since the seventies, intranasal mirror technology just obtains extensive use, becomes the milestone of nose section operation.But at present in operation owing to the blood stains camera lens, take out mirror body wiping and the mirror body inserted dyed not only or art district but also repeatedly by problems such as blood flood by blood stains, wasted a large amount of time of surgical doctor, and be difficult to the operation of hemorrhage position faster do meticulous, because the suction pump pressure controllability that uses is poor at present, can not satisfy the negative pressure different demand of different operative sites in addition to attracting.

Can have and a kind ofly can in art, wash camera lens in real time, clear up blood stains and do not make the loaded down with trivial details device of operation technique, be that the ENT ﹠ HN Surgery Dept. doctor looks forward to, because the needed attraction in position that operation is different and the pressure of flushing are different, the controlled flushing suction device of strength is better.The people is arranged abroad with monopolar electrocoagulation, suction catheter or syringe pipe and one 0 degree, the hard endoscope of 4mm is installed in the device of an one, be applied in the neurosurgery, but this certainly will increase the diameter of device, and nasal cavity space is limited, so this device is difficult to be applied to operation (the Bakshi A of nose section, A multifunctional, modified rigidneuroendoscopic system:clinical experience with 83 procedures.Technical note. (improved multifunction horniness neuroendoscopy system: 83 routine clinical experiences. the technical descriptioon manuscript), J Neurosurg (neurosurgery's magazine), in August, 2003; 99 (2): 421-5).The patent No. of announcing Patent Office of the People's Republic of China in July, 2002 is that 01252165.5 patent documentation has disclosed a kind of electricity and coagulates flushing aspirator, owing to what often need at nose basis cranii surgery is bipolar coagulation, monopolar electrocoagulation is not the function of using always, and can increase the diameter of body and the volume of handle, in addition because its pressure is uncontrollable, the shape of body can not be changed as required at any time, so neither a kind of ideal device.

The utility model content

This utility model takes into full account the various shortcomings that occur in similar at present or the relevant apparatus both at home and abroad, and is overcome.Its objective is to solve in the present intranasal videoendoscopic surgery to have blood stains camera lens and art district blood pollution problems, and do not increase the loaded down with trivial details of operation technique, reduce even eliminate the operation of taking-up scope wiping camera lens in traditional art.

For this reason, this utility model provides a kind of intranasal videoendoscopic surgery to wash attraction system with infinitely variable speeds, attract crossover connection by flushing, positive voltage regulator, draft regulator, the malleation bottle, negative pressure bottle, positive pressure source, negative pressure source and the rubber tube composition that connects each several part, wherein, it is the package assembly of outer tube and interior pipe that described flushing attracts crossover connection, the both sides of outer tube have the flushing water interface respectively and attract interface, the sidewall of interior pipe is provided with opening, described opening rotates by knob, thereby communicate with flushing water interface and attraction interface respectively, with the conversion that realizes that flushing attracts, the front end of described outer tube is a joint, is used to connect various suction aspirator tips.

Flushing attracts function to realize by a pipe in the art of flushing aspirator of the present utility model, and finish flushing attraction function by the rotation of knob and change, the strength of I ﹠ A can be regulated by just (bearing) voltage regulator, the pipe joint part of front end adapts with existing suction aspirator tip, so can change difform suction aspirator tip at any time according to the operation needs.This flushing aspirator be in the nasal endoscope operation in real time flushing camera lens, cleaning blood stains design, also can be applied to wash attraction needs in the frequent medical care precess of changing.
