Description

A kind of wire intermediate junction device of heat setting cutter

Technical field

The present invention relates to a kind of medical apparatus and instruments, particularly to a kind of heat setting cutter for Minimally Invasive Surgery.

Background technology

Minimally Invasive Surgery, is the operation utilizing the modern medical equipment such as peritoneoscope, thoracoscope and relevant device to carry out, and has that wound is little, pain light, recovers 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 to carry out solidifying and closing soft tissue by heat and pressure simultaneously, heat is made by low-voltage DC and is produced by resistance wire, electric current is not had to pass through tissue, the protein chain of the protein in gripper jaw is made to open under local heat energy effect, the hinge type structure that adjacent protein chain is formed by hydrogen bonded, with the sealing blood vessels broken ends of fractured bone, can make vessel closure, complete hemostatic function; Tissue additionally can also be made to melt, reach separate tissue, complete cutting purpose.

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 brings very big hidden danger to later use. Through extensively retrieval, not yet find ideal technical scheme.

Summary of the invention

The present invention is that the wire being provided at its inner portion easily is wound into shortcoming together in order to solve present stage heat setting cutter in the process used, and the wire intermediate junction device of a kind of heat setting cutter proposed.

To achieve these goals, present invention employs following technical scheme:

A kind of wire intermediate junction device of heat setting cutter, including shell, connect a stay tube in the enclosure, be connected the gripper jaw cooperated in the front end of a stay tube, it is characterized in that: at the rear end slip joint casing of a stay tube, sleeve pipe is socketed two contact tubes at a distance, each contact tube is socketed a brush respectively, each contact tube is connected with gripper jaw respectively by the first wire, and each brush connects electric-controlled box by the second wire.

On the basis of technique scheme, it is possible to have technical scheme further below:

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

Be connected a locking nut on a stay tube, and locking nut is locked with the front end face of sleeve pipe and coordinated.

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

Being additionally provided with two openings in the rear end of a stay tube, the first wire for connecting contact tube and gripper jaw is also separately positioned in opening, and the first described wire and the second wire all adopt enamel-covered wire.

The second wire being connected with electric-controlled box on brush master control button and control knob have been also respectively connected with.

It is an advantage of the current invention that: device provided by the invention is easy to operate, simple in construction is easy to process, and this device wire in use will not be wound into together because of the rotation of gripper jaw.

Accompanying drawing explanation

Fig. 1 is the basic structure schematic diagram of the present invention.

Detailed description of the invention

As shown in Figure 1, a kind of wire intermediate junction device of heat setting cutter, including shell 1, draw-in groove 10 it is provided with in shell 1, be connected a stay tube 2 in draw-in groove 10, be connected the gripper jaw 3 cooperated in the front end of a stay tube 2, it is characterized in that: be provided with screw thread in the outside of a stay tube 2, a stay tube 2 is threaded connection a sleeve pipe 4, the described ladder pipe that sleeve pipe 4 is an insulation being provided with three ladders, front two sections of ladders are socketed a contact tube 5 respectively, the symmetric position of the ladder after sleeve pipe 4 is respectively equipped with a through hole 4a, each contact tube 5 is socketed a brush 6 respectively, it is additionally provided with two openings in the rear end of a stay tube 2, each contact tube 5 welds with one end of first wire 8 respectively, each brush 6 connects electric-controlled box 9 by the second wire 11, first wire 8 is again respectively from stay tube 2 tube core, traverse in the opening of stay tube 2 and through hole 4a, the other end of every first wire 8 is respectively welded on single gripper jaw 3.

Be connected a locking nut 7 on a stay tube 2, and locking nut 7 is locked with the front end face of sleeve pipe 4 and coordinated.
