The specific embodiment

As Fig. 1～tubular type surgical operation Binding Instrument shown in Figure 4, comprise nail anvil 1 assembly and Binding Instrument body, nail anvil 1 assembly comprises nail anvil 1, pin anvil shaft 8, nail-anvil cap 2, the Binding Instrument body comprises fixed handle, percussion handle, anvil pull rod 3, the trocar 4, the trocar 4 is arranged on the top of anvil pull rod 3, wherein: the trocar 4 sidewalls have a loophole 5 at least, owing to be sealed with the light transmission piece that light transmissive material is made on the loophole 5 of the trocar 4, make the trocar 4 whole sealings of maintenance still, so do not influence its penetrate tissue.Nail-anvil cap 2 adopts light transmissive materials, can printing opacity, be provided with reflective convex lens group in it, and reflective convex lens group is made up of at least two convex lens, and be divided into reflective convex lens 6 and time reflective convex lens 7 by its arrangement position.At present in the middle of the reflective together convex lens 7 is hollow out, and the size of hollow out is corresponding with the internal diameter of pin anvil shaft 8.Pin anvil shaft 8 internal fixation have optical rod 9, be provided with light-emitting device and conductor 12 in the anvil pull rod 3, be provided with electric supply installation in the fixed handle, electric supply installation is located in the fixed handle of Binding Instrument body, it links to each other with light-emitting device by conductor 12, the light that light-emitting device penetrates is through the transmission of optical rod 9, and the reflective convex lens group of directive sees through nail-anvil cap 2 behind the light process secondary reflection and penetrates.Specifically, above-mentioned light-emitting device is a LED light emitting diode 10, and its top is connected with the trocar 4, and tail end is connected with conductor 12, and conductor 12 is lead or guide card.And described electric supply installation comprises cell sealing cabin 13, battery 14 and insulation film 15, and insulation film 15 1 ends are located at 13 bottoms, cell sealing cabin, and the other end links to each other with ejector pin bar 16 or screw mandrel.And on sidewall, be provided with pin-and-hole at above-mentioned anvil pull rod 3, the trocar 4, be buckled with hatchcover 17 on the cell sealing cabin 13 perpendicular to cross section.Certainly, described anvil pull rod sidewall also can adopt transparent material to make.

The first step is the installation to light source on the Binding Instrument body: at first the end with lead penetrates in the anvil pull rod 3, allows itself and LED light emitting diode 10 connect, and the hollow structure of the anvil pull rod 3 that then LED light emitting diode 10 postponed is put into wherein.Then the trocar 4 is enclosed within on the anvil pull rod 3, by pin 11 trocar 4 further is fixed on the anvil pull rod 3, simultaneously also can come LED light emitting diode 10 is fixed, guarantee that anvil pull rod 3 can not make the trocar 4 and LED light emitting diode 10 misplace in the process of motion by pin 11.The other end with lead is connected on the cell sealing cabin 13 subsequently, and an end of insulation film 15 is covered the bottom in cell sealing cabin 13, then its other end is adhered on the ejector pin bar 16, makes insulation film 15 follow 16 motions of ejector pin bar.At last set of cells 14 is placed in the cell sealing cabin 13 in order, buckles hatchcover 17, finish installation light source.

Second step was the concrete installation to optical rod 9 and nail-anvil assembly: at first nail anvil 1 and pin anvil shaft 8 tops are riveted, to put into pin anvil shaft 8 to optical rod 9 then, in order to guarantee the stability of light in transmission course, promptly can not produce shake because optical rod 9 displacement occurs, be unfavorable for operation enforcement, thereby optical rod 9 and pin anvil shaft 8 are sticked together.In order to take into account dispersing and penetration performance of light simultaneously, following reflective convex lens 7 centres are designed for hollow out, and the size of hollow out is corresponding with the internal diameter of pin anvil shaft 8.To descend the outer surface adhesion of reflective convex lens 7 and nail anvil 1 subsequently, go up the inner surface adhesion of reflective convex lens 6 and nail-anvil cap 2, and reflective convex lens group be carried out one fix.At last, the printing opacity nail-anvil cap 2 that transparent material is made is installed on the nail anvil 1, finishes the installation of optical rod 9 and nail-anvil assembly.

Its concrete use is as follows: after Binding Instrument entered tubular tissue, the implementer began to undergo surgery, and when it drives 16 motions of ejector pin bar by handle, had also driven moving of insulation film 15.After in a single day insulation film 15 was taken out of from cell sealing cabin 13 by ejector pin bar 16, the luminous lighting circuit was unlocked, and that is to say that LED light emitting diode 10 is lighted.This just makes the opening process of light source simple and settle at one go, and button need not be set increases trivial step.Then, the light that penetrates from LED light emitting diode 10 passes the loophole 5 that the trocar 4 sidewalls have, and the transmission of the optical rod 9 that is provided with in the process anvil pull rod 3 arrives the last reflective convex lens 6 in the nail-anvil cap 2 earlier.Go up reflective convex lens 6 and light is reflexed to down reflective convex lens 7 by its structure, last, see through transparent nail-anvil cap 2 through secondary reflection and shine tissue, come thus to throw light on to sealing dark tubular tissue inside.

By allowing tubular type surgical operation Binding Instrument have illumination functions, make the implementer of operation need not singlely rely on the sound that apparatus sent to judge to coincide whether finish, also not only come the molding quality of perception nail by the touch of hands, can also illuminate operative site by Binding Instrument, directly it is observed, determine the bookbinding distance very intuitively and judge the bookbinding effect, guaranteed the levels of precision of operation.Avoid the implementer because the gap of experience and level causes the error on the sense organ in the operation process, caused the danger of operative failure.

If conductor 12 adopts the lamellar guide card of metal material to replace lead, can play the effect of transmission electricity equally.

Certainly, more than only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.In addition to the implementation, this utility model can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in this utility model scope required for protection.
