Description

With the laparoscopic surgery nipper of suction pump
Technical field
This utility model relates to medical science laparoscopic surgical instruments, is specifically related to the laparoscopic surgery nipper being with suction pump.
Background technology
Laparoscopic surgery with accurate, Wicresoft is famous, this needs operator to use one to the local operation open country several nipper grasped surrounding tissue, tractive builds a Stability Analysis of Structures, angle is suitable, to carry out accurate operation usually.But, can the situations such as hemorrhage be run into unavoidably in laparoscopic procedures, suction pump must be used to suck blood in time and stop blooding to expose petechia; Moreover, the spatial operation narrow in deep, such as, during the pelvic cavity lock out operation of low Low Level rectum, the operation of ultrasound knife or electric knife can produce a large amount of high temperature steam fogs, and very easily fuzzy video gathers camera lens, and impact is observed, if be aided with suction pump to help to siphon away steam fog, situation can be improved greatly.If because hemorrhage, the steam fog interference of local, frequent transitions operating theater instruments, will inevitably destroy the operating field originally exposed, interference procedure, impact operation fluency.Part operator has and uses suction pump to replace the partial function of nipper to carry out the custom being separated, appearing, but the straight rod type suction pump used at present can not be competent at both functions completely.Therefore, need to design a kind of laparoscopic surgery nipper apparatus having suction pump function concurrently, can need not change apparatus and can carry out grasping, draw or the various operation such as attraction in operation.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of laparoscopic surgery nipper with suction pump, realizes carrying out in laparoscopic surgery grasping, can play while draw operations the function of suction pump.
For achieving the above object, the laparoscopic surgery nipper of the band suction pump designed by this utility model, comprise fixed handle, flexible handle, hollow clamp handle, the head of described fixed handle and flexible handle is articulated and connected, described one end of hollow clamp handle is fixedly connected with the head end of fixed handle, the other end of described hollow clamp handle is fixedly connected with fixing nipper head, the root of described fixing nipper head and the root side of movable nipper head are articulated and connected, moveable draw bar is provided with in the inner chamber of described hollow clamp handle, one end of described draw bar and the head end of flexible handle are articulated and connected, the other end of described draw bar and the root opposite side of movable nipper head are articulated and connected, its special character is:
The one side that described fixing nipper head is relative with movable nipper head respectively offers the first longitudinal fluting and second longitudinal fluting of cross section semicircular in shape, form hollow circular passage when described first longitudinal fluting and the occlusion of the second longitudinal fluting, described first longitudinal fluting is the wave structure of mutually mating with the both sides occlusal surface of the second longitudinal fluting;
Also suction catheter is provided with in described hollow clamp handle inner chamber, one end of described suction catheter is connected with described hollow circular passage, the other end of described suction catheter draws the first suction catheter and the second suction catheter by three way cock, described first suction catheter and the negative tube orifice being opened in hollow clamp handle surface, described second suction catheter is connected with the steam-hole type switch being opened in its surface through described fixed handle inner space, and described negative tube interface is connected with external connecting negative pressure equipment by sebific duct.
Further, described fixing nipper head and/or movable nipper head surface offer the side opening through with described hollow circular passage, and like this when attraction operates, a small amount of steam fog or blood also can be inhaled into suction catheter from side opening.
Further, described movable nipper head surface offers 6 side openings through with described hollow circular passage, and described fixing nipper head surface offers 3 side openings through with described hollow circular passage.
Above-mentioned first arcuate groove and the second arcuate groove both sides occlusal surface are the wave design matched each other, and it is air tight that this contributes to occlusion sealing; When negative pressure equipment is bled, steam-hole type switch opens, at this moment the negative pressure of suction catheter is less; When finger blocks steam-hole type switch, at this moment the second suction catheter is in closed state, and suction catheter negative pressure increases, and can be used for attracting steam fog or liquid substance (as blood).
Specific operation process of the present utility model is as follows: when using as nipper, the design possess completely like product various clampings, draw, the function such as to recommend; During the work of external connecting negative pressure equipment, if need to attract steam fog or blood, then closed fixing nipper head and movable nipper head, thus form a circular channel, finger blocks steam-hole type switch, and steam fog or blood are mainly inhaled into suction catheter from the port of the circular channel in nipper head portion.
The utility model has the advantage of: achieve a tool multiplex, avoid and frequently change apparatus, interrupt operation rhythm; When carrying out lock out operation with ultrasound knife, electric knife, this utility model design not only can help to appear, and can also siphon away the steam fog that high temperature microstructure produces in time, thus prevents screen from gathering lens blur, keeps getting a clear view, avoids frequent wiping camera lens; In the hemorrhage or highly difficult accurate operation of process, this utility model design possess simultaneously attraction and accurate clamp, traction effect, excessive risk operation can be completed within the shortest time, this has very important meaning for highly difficult operation, simultaneously, due to this utility model design operation method thereof and skill and conventional apparatus no significant difference at present, jamais vu can not be produced and sense of conflicting for the operator being accustomed to existing apparatus, be easy to clinical application.
