Abstract
The utility model provides a pair of holding forceps for a central bar of a laparoscopic stapler. The holding forceps comprise a forcep part, a handheld handle, a casing and a pull rod which is arranged in the casing and connects the forcep part with the handheld handle, wherein the forcep part comprises two forcep pieces adopting arc structures and an opening and closing device for connecting the forcep pieces and the pull rod; and the handheld handle comprises a first handle part fixed at the rear end of the casing as well as a second handle part which can rotate around the first handle part, and the pull rod is connected onto the second handle part. The holding forceps for the central bar of the laparoscopic stapler can tightly clamp the central bar of a staple butting seat.
Description
Technical field
This utility model relates to medical instruments field, anastomat center-pole holding forceps under espespecially a kind of peritoneoscope.
Background technology
In laparoscopic surgery, after nail supporting base need to being connected with body, could coincide smoothly at present, and nail supporting base center-pole is cylindrical structural, conventionally need to adopt peritoneoscope holding forceps to complete coincideing between nail supporting base and body by controlling the center-pole of described nail supporting base.But use common peritoneoscope holding forceps when the center-pole of the described nail supporting base of clamping, because the jaw of holding forceps can not closely cooperate with described center-pole well, easily there is the situation that clamping is not tight, cannot smoothly nail supporting base be connected smoothly with body, and easily cause slippage, cause intestinal tube far-end or other tissue injurys, even cause serious consequence.
Given this, anastomat center-pole holding forceps under a kind of peritoneoscope of necessary exploitation.
Utility model content
This utility model provides anastomat center-pole holding forceps under a kind of peritoneoscope of closely Clamping Center bar.
For addressing the above problem, this utility model provides anastomat center-pole holding forceps under a kind of peritoneoscope, comprise pincers portion, hand holding handle, sleeve pipe and be placed in described sleeve pipe and connect the pull bar of described pincers portion and hand holding handle, described pincers portion comprises two curved structure clamp pieces and connects the open and close device of described clamp piece and described pull bar, described hand holding handle comprises and is fixed on the first shank of described sleeve pipe rear end and second shank that can rotate around described the first shank, and described pull bar is connected on described the second shank.
The arcuate structure subtend of described two clamp pieces arranges.
The height of described two clamp pieces is 0.5cm, and the diameter of described sleeve pipe is 1cm.
Between the first shank of described hand holding handle and the second shank, be provided with catch mechanism.
Described pull bar is connected in the top of described the second shank.
Angle between the central shaft of described clamp piece and the central shaft of described sleeve pipe is 60 degree
Compared to prior art, under this utility model peritoneoscope, anastomat center-pole adopts the arcuate structure that can closely clamp described nail supporting base center-pole by the clamp piece of holding forceps, has avoided pincers portion in prior art cannot closely clamp the defect of described center-pole.
Accompanying drawing explanation
Fig. 1 is the structural representation that under this utility model peritoneoscope, anastomat center-pole is used holding forceps.
Fig. 2 is the pincers portion enlarged drawing that under this utility model peritoneoscope, anastomat center-pole is used holding forceps.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.
Refer to shown in Fig. 1, under peritoneoscope of the present utility model, anastomat center-pole comprises pincers portion 10, hand holding handle 30, sleeve pipe 20, is placed in the interior pull bar 21 for connecting clamp portion 10 and hand holding handle 30 of sleeve pipe 20 with holding forceps.
Described pincers portion 10 comprises two curved structure clamp pieces 11 and connects the open and close device 40 of described clamp piece 11 and described pull bar 21.Through experimental verification, the optimum height h of described clamp piece 11 is 0.5cm, in use, and the clamping that can closely the cylindrical center bar (not shown) of nail supporting base be closely cooperated of described arc clamp piece 11.The arcuate structure subtend of described two clamp pieces 11 arranges.
Described hand holding handle 30 comprises and is fixed on the first shank 31 of described sleeve pipe 20 rear ends 22 and second shank 32 that can rotate around described the first shank 31, between described the first shank 31 and the second shank 32, be provided with catch mechanism 33, the end of described pull bar 21 is connected in described the second shank 32 tops.
The diameter of described sleeve pipe 20 is 1cm, and the angle a between the central shaft of described clamp piece 11 and the central shaft of described sleeve pipe 20 is 60 degree.
During use, two clamp pieces 11 of described pincers portion of elder generation 10 are placed in the peripheral part of described center-pole; Operate hand holding handle 30 again and pull described pull bar 21, under the pulling of described hand holding handle 30, described pull bar 21 pulls described open and close device 40 to control described two clamp pieces 11 and clamps described center-pole; Finally, when described two clamp pieces 11 have clamped after center-pole, the catch mechanism 33 on described hand holding handle 30 holds the distance between location the first shank 31, the second shank 32 so that described clamp piece 11 continues to clamp described center-pole.
Compared to prior art, under peritoneoscope of the present utility model, anastomat center-pole adopts the arcuate structure that can closely clamp described nail supporting base center-pole by the clamp piece 11 of holding forceps, has avoided pincers portion in prior art cannot closely clamp the defect of described center-pole.
The foregoing is only preferred embodiment of the present utility model; be not limited to this utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in the scope of this utility model protection.
