Heat setting cutter are one of most important apparatuses of thermal weld technological system in Minimally Invasive Surgery, gripper jaw is one of vitals of heat setting cutter, the gripper jaw that present stage uses is generally the combination of linkage or higher pair mechanism and linkage, electricity controls to rely on pure direct current voltage reulation, electric current for heating contacts conducting by hinge or higher pair, and these designs all exist certain risk hidden danger and limitation in production with in using.
Heat setting cutter small-sized, in narrow space, the component of drive mechanism and the size of hinge minimum.The complex structure of hinge, bearing capacity is little, and chucking power is little, and manufacture difficulty is large.The relative motion using the heat setting cutter of high auxiliary drive gear to exist to slide between component and rotate and the loose contact that produces, cause local electrical resistance to increase and fever phenomenon, even produce electric spark.Through extensively retrieval, not yet find ideal technical scheme.
Summary of the invention
The present invention is to provide a kind of processing and easy to assembly, the object of the connecting device of the gripper jaw of the heat setting cutter of use safety, and the connecting device of a kind of heat setting cutter gripper jaw of proposition.
To achieve these goals, present invention employs following technical scheme:
A connecting device for heat setting cutter gripper jaw, comprises shell, connects stay pipe in the enclosure, and be connected in the front end of stay pipe two gripper jaws cooperatively interacted, and it is characterized in that:
A, on stay pipe, be socketed outer tube, one end of outer tube is fixedly connected with in the enclosure, be provided with two in the front end of stay pipe and symmetrical take mouth, two symmetrical chutes are also provided with in the front end of stay pipe, two described chutes run through line and two take mouth to run through line perpendicular, two symmetrical fixing holes are provided with, each fixing hole and corresponding chute corresponding matching in outer tube front end;
B, be provided with attachment strap in the outside of each gripper jaw rear end, a contiguous block is respectively equipped with in the inner side of each gripper jaw rear end, the contiguous block corresponding matching of two gripper jaws, the contiguous block matched also is respectively equipped with the pin-and-hole of corresponding matching, two gripper jaw rear ends are all arranged in stay pipe, each attachment strap is connected with corresponding mouth of taking respectively, and outer tube, stay pipe and two gripper jaws through fixing hole, chute and pin-and-hole, link together by fitting pin successively.
On the basis of technique scheme, following further technical scheme can also be had:
The rear end of described outer tube is provided with flange, and flange is connected in the draw-in groove of shell.
Described outer tube is connected a rotating seat, rotating seat is arranged on enclosure, rotating seat is provided with opening, outer tube is provided with through hole, opening and through hole corresponding matching, be connected conduit in opening, conduit and outer tube conducting, to be also connected an end cap at the opening part of described conduit.
Described rotating seat is a conical sleeve, and rotating seat conveniently can regulate the clamping orientation of gripper jaw, and the conduit that rotating seat is arranged is conducive to the cleaning to gripper jaw.
Be provided with a boss with opening in described shell, be connected stay pipe in the opening of boss.Described outer tube also matches with shell, and outer tube is fixedly connected with the draw-in groove of shell by the flange of its end, stay pipe can slide by outer tube relatively, when stay pipe slides, take cooperatively interacting of the attachment strap of mouth and gripper jaw by stay pipe, two gripper jaws are rotated around fitting pin, the wire connecting gripper jaw can pass from the center of stay pipe, so namely, solve the power transmission problem of gripper jaw, solve again the problem of generating heat because loose contact causes local electrical resistance to increase.
The invention has the advantages that: this device has that structure is simple, the feature of easily processing and assembling, facilitates maintenance and the replacing of gripper jaw, and provide larger and stable blessing power for gripper jaw.
