Description
Technical field
This utility model relates to technical field of medical instruments, specifically, is a kind of scalable suction pump.
Background technology
Suction pump is that clinical conventional indispensability rescues instrument, is often applied to micro-wound surgical operation, adult surgical, pediatric surgical operation, content, flushing liquor in hemorrhage, exudate, pus, the hollow organ that use suction pump can attract in operating field, make operating field clear, decreasing pollution chance.Also can be used for general anesthesia patient and absorb sputum.
In operation process, because body physiological structure is different, the suction catheter specification that diverse location place needs is also different, in abdominal operation process, intraperitoneal is hemorrhage and sepage sometimes, needs to use suction apparatus attracts, wherein attract effect to reduce wound and increasing, usually select the suction catheter with radian; In addition, in adult surgical, its exudate, puss etc. are more, need the suction catheter using specification thicker, and in pediatric surgical operation, exudate, pus etc. are relatively less, only need the suction catheter that specification is less; Secondly, in operation actual mechanical process, because of special occasions, device location restriction, attract the factors such as position, it needs the length specification of suction catheter different, the apneusis skirt of some needs, and the short suction catheter of some needs; Further, in same operation process, in order to obtain good operating field situation, needing the suction catheter changing different radian, length and thickness, being convenient to attract and appear.
The handle of existing suction pump and suction catheter are integrated, suction catheter can not be converted, and then the thickness of suction catheter, length, radian can not change, therefore, when different parts being attracted during operation, the thickness of suction catheter, length, radian can be improper, all the more so during Minimally Invasive Surgery, and these all can affect the carrying out of operation.
Chinese patent literature CN201310180009.0, at on 05 15th, 2013 applying date, patent name is " surgical aspirator ", disclose a kind of surgery Medical suction unit, comprise suction catheter, described suction catheter is Double-layered transparent plastic flexible pipe, described round trip transparent plastic hose is provided with spiral wire, one end of described suction catheter is connected with capsule ball suction nozzle, described capsule ball suction nozzle is provided with liquid sucting port, the other end of described suction catheter is communicated with negative pressure suction device, described negative pressure suction device comprises push-and-pull pipe, the push-pull bar that described push-and-pull pipe is provided with piston and is fixedly connected with piston, described push-and-pull pipe is also provided with drainage tube, described drainage tube is provided with drain valve.
In such scheme, according to the curvature in operation chamber, with hands, plastic tube is bent to corresponding curvature, after loosing one's grip, plastic tube keeps curvature form constant under the dynamics effect of spiral wire, thus enable this suction pump be applicable to different bending tracts, but suction catheter can be suitable under straight tube and curved tube two kinds of specifications, then cannot meet for the thickness of suction catheter, length specification.
In sum, need the suction catheter of a kind of replaceable different radian, length and thickness badly, be convenient to appear, obtain good operating field, improve surgical effect and safety, increase the scalable suction pump of work efficiency.And yet there are no report about this suction pump.
