Description
Technical field
The present invention relates to the medical machinery field, particularly the connecting device of the solidifying cutter gripper jaw of a kind of heat.
Background technology
Minimally Invasive Surgery, be 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 light, recover fast superiority.Along with the progress of technology, Minimally Invasive Surgery has been deep into operating various field.
The solidifying cutter of heat are one of most important apparatuses of thermal weld technological system in Minimally Invasive Surgery, gripper jaw is one of vitals of the solidifying cutter of heat, 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, electric current for heating contacts conducting by hinge or higher pair, and these designs all exist certain risk hidden danger and limitation in producing and using.
Heat is coagulated the small-sized of cutter, and 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.Use the solidifying cutter of heat of high auxiliary drive gear to have between member the loose contact of the caused by relative motion of sliding and rotating, cause local electrical resistance to increase and fever phenomenon even produces electric spark.Through extensively retrieval, not yet find comparatively desirable technical scheme.
Summary of the invention
The present invention is for a kind of processing and easy to assembly is provided, and uses the purpose of connecting device of the gripper jaw of the solidifying cutter of safe heat, and the connecting device of the solidifying cutter gripper jaw of a kind of heat proposed.
To achieve these goals, the present invention has adopted following technical scheme:
The connecting device of the solidifying cutter gripper jaw of a kind of heat, comprise 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, be socketed outer tube on stay pipe, one end of outer tube is fixedly connected with in the enclosure, be provided with the mouth of taking of two symmetries at the front end of stay pipe, also be provided with the chute of two symmetries at the front end of stay pipe, described two chutes run through that line and two take mouthful to run through line perpendicular, be provided with the fixing hole of two symmetries at the outer tube front end, each fixing hole and corresponding chute corresponding matching;
B, in the outside of each gripper jaw rear end, be provided with attachment strap, be respectively equipped with a contiguous block in the inboard of each gripper jaw rear end, the contiguous block corresponding matching of two gripper jaws, also be respectively equipped with the pin-and-hole of corresponding matching on the contiguous block matched, two gripper jaw rear ends all are 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, following further technical scheme can also be arranged:
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, be provided with opening on rotating seat, be provided with through hole on outer tube, 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 also is connected.
Described rotating seat is a conical sleeve, and rotating seat can conveniently be regulated the clamping orientation of gripper jaw, and the conduit arranged on rotating seat is conducive to the cleaning to gripper jaw.
Be provided with a boss with opening in described shell, stay pipe is connected 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 outer tube relatively 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 invention has the advantages that: this device has characteristics simple in structure, that easily process and assemble, facilitates maintenance and the replacing of gripper jaw, and provides the larger and stable power of holding that adds for gripper jaw.
