Minimally Invasive Surgery, is the operation that utilizes the modern medical equipment such as peritoneoscope, thoracoscope and relevant device to carry out, and has that wound is little, pain is light, recover fast superiority.Along with the progress of technology, Minimally Invasive Surgery has been deep into operating various field.
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, present stage, the gripper jaw that uses was generally the combination of linkage or higher pair mechanism and linkage, electricity is controlled and is relied on pure direct current voltage reulation, for the electric current heating, by hinge or higher pair, contact conducting, all there is certain risk hidden danger and limitation in these designs in producing and using.
Heat setting cutter small-sized, in narrow space, the member of drive mechanism and the size of hinge are minimum.The complex structure of hinge, bearing capacity is little, and chucking power is little, and manufacture difficulty is large.The loose contact of the caused by relative motion of using the heat setting cutter of high auxiliary drive gear to exist to slide between member and rotating, causes local electrical resistance to increase and fever phenomenon even produces electric spark.Through extensively retrieval, not yet find comparatively desirable technical scheme.
Utility model content
This utility model is for a kind of processing and easy to assembly is provided, and uses the object of connecting device of the gripper jaw of safe heat setting cutter, and the connecting device of a kind of heat setting cutter gripper jaw proposing.
To achieve these goals, this utility model has adopted following technical scheme:
A connecting device for heat setting cutter gripper jaw, comprises shell, connects in the enclosure stay pipe, at the front end of stay pipe two gripper jaws that cooperatively interact that are connected, 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, at the front end of stay pipe, be provided with two symmetrical mouths of taking, front end at stay pipe is also provided with two symmetrical chutes, two described chutes run through that line and two take mouthful to run through line perpendicular, at outer tube front end, be provided with two symmetrical fixing holes, each fixing hole and corresponding chute corresponding matching;
B, in the outside of each gripper jaw rear end, be provided with attachment strap, in the inner side of each gripper jaw rear end, be respectively equipped with a contiguous block, the contiguous block corresponding matching of two gripper jaws, on the contiguous block matching, be also 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 the corresponding mouth of taking respectively, and fitting pin through fixing hole, chute and pin-and-hole, links together outer tube, stay pipe and two gripper jaws successively.
On the basis of technique scheme, can also there is following further technical scheme:
The rear end of described outer tube is provided with flange, and flange is connected in the draw-in groove of shell.
A rotating seat is connected on described outer tube, rotating seat is arranged on enclosure, on rotating seat, be provided with opening, on outer tube, be provided with through hole, opening and through hole corresponding matching, the conduit that is connected in opening, conduit and outer tube conducting, at the opening part of the described conduit end cap that is also connected.
Described rotating seat is a conical sleeve, and rotating seat can conveniently regulate the clamping orientation of gripper jaw, and the conduit arranging on rotating seat is conducive to the cleaning to gripper jaw.
In described shell, be provided with one with the boss of opening, stay pipe is connected in the opening of boss.Described outer tube also matches with shell, and outer tube is fixedly connected with by the flange of its end and the draw-in groove of shell, stay pipe relatively outer tube slides, when stay pipe slides, by taking mouthful of stay pipe and cooperatively interacting of the attachment strap of gripper jaw, two gripper jaws are rotated around fitting pin, the wire of connection gripper jaw can pass from the center of stay pipe, so, solved the power transmission problem of gripper jaw, solved again because loose contact causes local electrical resistance and increased the problem of generating heat.
The utility model has the advantage of: this device has feature simple in structure, that easily process and assemble, facilitates maintenance and the replacing of gripper jaw, and provide the larger and stable power of holding that adds for gripper jaw.
