Abstract
The utility model discloses a kind of novel anti-error suction, antiblocking laparoscope suction unit, the control valve comprising suction catheter and be connected with suction catheter, the head end of suction catheter is provided with a band filter screen that can freely dismantle pullover, decompression side opening is offered in the front end of suction catheter, it is simple that this utility model not only has structure, design advantage cleverly, and not easily by clot when using, the foreign matters from being blockeds such as calculus, the tissue apposition caused because negative pressure is excessive can be avoided when the hollow organ intracavity such as gallbladder attract, can avoid in the intraperitoneal normal structures such as omentum majus by mistake suction tube when intraperitoneal attracts, if suction pump head end generation foreign body obstruction, the pullover removing obturator of lower filter screen can be dismantled in time.
Description
Technical field
This utility model relates to a kind of novel anti-error suction, antiblocking laparoscope suction unit, belongs to attractor for laparoscope renovation technique field.
Background technology
At present, attractor for laparoscope is for absorbing hands intraoperative hemorrhage, exudate, pus, content in thoracic organ, make operation clear, decreasing pollution chance, the principle of suction pump is very simple, manufacture the negative pressure state of its sucking head exactly, material outside sucking head will extrude to sucking head by such atmospheric pressure, thus complete the effect of " attraction ", existing attractor for laparoscope is made up of suction catheter and control valve two parts, control valve is by spring, valve core, input pipe and outlet tube composition, easily by clot when but existing attractor for laparoscope uses, the foreign matters from being blockeds such as calculus, the tissue apposition caused because negative pressure is excessive when the hollow organ intracavity such as gallbladder attract, and when intraperitoneal attracts by the intraperitoneal normal structures such as omentum majus by mistake suction tube, cause bad impact.
Application number is 200320113978.6, publication number is the patent of a kind of antiblocking laparoscope suction unit of CN2649021, in this patent application, the head end of suction catheter is provided with filter screen, in this patent, filter screen is directly installed on the head end of suction catheter, but the head end area of suction catheter is little, attract weak effect, and when foreign material miss after in suction tube, be not easy cleaning, dismounting extremely bothers, so existing attractor for laparoscope is still perfect not.
Summary of the invention
The purpose of this utility model is: provide a kind of structure simple, practical, assembly and disassembly is simple, not easily by the foreign matters from being blocked such as clot, calculus during use, the tissue apposition caused because negative pressure is excessive can be avoided when the hollow organ intracavity such as gallbladder attract, can avoid the novel anti-error suction of one in the intraperitoneal normal structures such as omentum majus by mistake suction tube, antiblocking laparoscope suction unit when intraperitoneal attracts, to overcome the deficiencies in the prior art.
This utility model is constructed as follows: a kind of novel anti-error suction, antiblocking laparoscope suction unit, the control valve comprising suction catheter and be connected with suction catheter, the head end of suction catheter is provided with a band filter screen that can freely dismantle pullover, offers decompression side opening in the front end of suction catheter.
Filter screen is pullover is connected by screw thread for suction catheter and band.
Described band filter screen is pullover is that tubulose is pullover.
Band filter screen set headgear head length is 3cm, and diameter is 1cm, and the diameter of mesh is 3mm, and the diameter of decompression side opening is 2mm.
Compared with prior art, it is simple that this utility model not only has structure, design advantage cleverly, and not easily by the foreign matters from being blocked such as clot, calculus when using, the tissue apposition caused because negative pressure is excessive can be avoided when the hollow organ intracavity such as gallbladder attract, can avoid when intraperitoneal attracts, by the intraperitoneal normal structures such as omentum majus by mistake suction tube, if suction pump head end generation foreign body obstruction, the pullover removing obturator of lower filter screen can being dismantled in time.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation;
Fig. 2 be suction catheter with band filter screen is pullover be separated time structural representation;
Description of reference numerals: 1-suction catheter, 2-control valve, 3-is with filter screen pullover, and 4-reduces pressure side opening.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Enforcement of the present utility model: a kind of novel anti-error suction, antiblocking laparoscope suction unit, the control valve 2 comprising suction catheter 1 and be connected with suction catheter 1, the head end of suction catheter 1 is provided with a band filter screen that can freely dismantle pullover 3, offers decompression side opening 4 in the front end of suction catheter 1.
Suction catheter 1 is connected by screw thread with band filter screen pullover 3.
This utility model offers the excessive decompression side opening 4 of anti-negative pressure in suction catheter 1 front end.
Described band filter screen pullover 3 is that tubulose is pullover.
The pullover 3 pullover length of band filter screen are 3cm, and diameter is 1cm, and the diameter of mesh is 3mm, and the diameter of decompression side opening 4 is 2mm.
The band filter screen pullover 3 that this utility model is arranged at suction catheter 1 head end, effectively can increase the adsorption area of attractor for laparoscope, and for convenience detach.
The design makes improvements on original attractor for laparoscope, structure is simple, not easily by the foreign matters from being blocked such as clot, calculus during use, the tissue apposition caused because negative pressure is excessive can be avoided when the hollow organ intracavity such as gallbladder attract, can avoid in the intraperitoneal normal structures such as omentum majus by mistake suction tube when intraperitoneal attracts, if suction pump head end generation foreign body obstruction, the pullover removing obturator of lower filter screen can be dismantled in time.
