Description

A kind of wire intermediate junction device of heat setting cutter

Technical field

This utility model relates to a kind of medical apparatus and instruments, particularly a kind of heat setting cutter for Minimally Invasive Surgery.

Background technology

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, its principle is solidified simultaneously and sealed soft tissue by heat and pressure, heat is to produce by resistance wire by low-voltage DC, do not have electric current to pass through tissue, under the effect of local heat energy, the protein chain of the protein in gripper jaw is opened, the hinge type structure that adjacent protein chain forms by hydrogen bonded, with the sealing blood vessels broken ends of fractured bone, can make blood vessel sealing, completes hemostatic function; Also can make in addition tissue melt, reach separate tissue, complete cutting object.

Existing heat setting cutter, the heating wire in its gripper jaw is directly connected with electric-controlled box mostly, and in use, the wire in heat setting cutter is easily wound into together in this design, and this has brought very big hidden danger to later use.Through extensively retrieval, not yet find comparatively desirable technical scheme.

Utility model content

This utility model is that the wire of the portion that sets within it is easily wound into shortcoming together in order to solve present stage heat setting cutter in the process of using, and the wire intermediate junction device of a kind of heat setting cutter that propose.

To achieve these goals, this utility model has adopted following technical scheme:

A kind of wire intermediate junction device of heat setting cutter, comprise shell, connect in the enclosure stay pipe, the gripper jaw that is connected and cooperatively interacts at the front end of stay pipe, it is characterized in that: at the rear end of stay pipe slip joint casing, on sleeve pipe, be socketed the contact tube of two segment distances of being separated by, on each contact tube, be socketed respectively a brush, each contact tube is connected with gripper jaw respectively by wire, and each brush connects electric-controlled box by wire.

On the basis of technique scheme, can there is following further technical scheme:

Described sleeve pipe is the ladder pipe that is provided with three ladders, on front two sections of ladders, is socketed respectively a contact tube, and described contact tube is copper pipe, and the certain angle of being separated by the ladder below of sleeve pipe is respectively equipped with a through hole, and wire passes respectively from through hole.

The locking nut that is connected on stay pipe, locking nut coordinates with the front end face locking of sleeve pipe.

Be provided with in the enclosure draw-in groove, draw-in groove and stay pipe are connected, and the outside of described stay pipe is provided with screw thread, and sleeve pipe and stay pipe are threaded connection, and described sleeve pipe is insulator,

In the rear end of stay pipe, be also provided with two openings, for connecting the wire of contact tube and gripper jaw, be also separately positioned in opening, described wire all adopts enamel-covered wire.

On the wire being connected with electric-controlled box, be also connected with respectively master control button and control knob on brush.

The utility model has the advantage of: the device that this utility model provides is easy to operate, simple in structure, easy to process, this installs wire in use and can not be wound into together because of the rotation of gripper jaw.

Accompanying drawing explanation

Fig. 1 is basic structure schematic diagram of the present utility model.

The specific embodiment

As shown in Figure 1, a kind of wire intermediate junction device of heat setting cutter, compriseshell 1, inshell 1, be provided with draw-ingroove 10, staypipe 2 is connected in draw-ingroove 10, the gripper jaw 3 that is connected and cooperatively interacts at the front end ofstay pipe 2, it is characterized in that: the outside atstay pipe 2 is provided with screw thread, onstay pipe 2, be threaded connection a sleeve pipe 4, described sleeve pipe 4 is a ladder pipe that is provided with the insulation of three ladders, on front two sections of ladders, be socketed respectively a contact tube 5, the symmetric position of the ladder after sleeve pipe 4 is respectively equipped with a throughhole 4a, on each contact tube 5, be socketed respectively a brush 6, in the rear end ofstay pipe 2, be also provided with two openings, each contact tube 5 welds with one end of awire 8 respectively, each brush 6 connects electric-controlledbox 9 by wire,wire 8 is again respectively from staypipe 2 tube cores, in the opening ofstay pipe 2 and throughhole 4a, pass, the other end of everywire 8 is welded on respectively on single gripper jaw 3.

The locking nut 7 that is connected onstay pipe 2, locking nut 7 coordinates with the front end face locking of sleeve pipe 4.
