The specific embodiment

Below in conjunction with the drawings and specific embodiments this utility model is described further.

As depicted in figs. 1 and 2, a kind of medical electric coagulation forceps, comprise base, tweezer body and electrode tip holder 1-3, the tweezer body comprises tweezer point 1-1 and tweezer bar 1-2, there is plug 1-4 electrode tip holder 1-3 rear end, a described side tweezer bar 1-2 links to each other by being movably hinged 1-7 with tweezer point 1-1, and the below of tweezer point 1-1 link has the first inclined-plane 1-11, and tweezer bar 1-2 corresponding position has the second inclined-plane 1-12 that adapts with it; Also be provided with push-pull bar 1-8 on the described tweezer bar 1-2, its front end and tweezer point 1-1 links to each other, and the rear end links to each other with sliding shoe 1-9, and this sliding shoe 1-9 is stuck in the sliding tray 1-10 on the tweezer bar 1-2; Be embedded with a weep pipe 1-5 in described tweezer bar 1-2 and the tweezer point 1-1, the entrance of this weep pipe 1-5 is positioned at tweezer point 1-1 front end, and outlet is positioned at electrode tip holder 1-3 rear end, and its exit also is provided with interface 1-6.

During use, the interface of weep pipe linked to each other with external water pipe to get final product.Tweezer bar and tweezer point level then pulls back sliding shoe and gets final product if desired; The bending of tweezer point then pushes away sliding shoe forward forward if desired, and at this moment, under the effect of push-pull bar, the tweezer point can be bent downwardly by nature, till first inclined-plane and the applying of second inclined-plane.Therefore, this structure can be adjusted the angle of tweezer point as required, realizes the function of dripping of multi-angle.

As shown in Figure 3 and Figure 4, two through hole 2-2 that adapt with electric coagulation forceps tweezer bar are arranged on the base 2-1, through hole 2-2 below is provided with cavity volume 2-3; Fix two sliding tray 2-4 on the inwall of cavity volume 2-3 both sides respectively, all blocking in the sliding tray 2-4 has movable pulley 2-5, also is connected with connecting rod 2-6 and an auxiliary wiping 2-7 on the movable pulley 2-5 in turn; Fixedly there is motor 2-9 cavity volume 2-3 north side, and motor 2-9 outfan connects ball screw 2-15, and ball screw 2-15 front end is connected with horizon bar 2-8, and the two ends of this horizon bar 2-8 all are equipped with a main wiping 2-10; Two fixed pulley 2-18 are fixedly arranged on the inwall in cavity volume 2-3 southern side; The end of described movable pulley 2-5 connects with corresponding sliding tray 2-4 inwall by spring 2-16, and the other end then is fixed on the horizon bar 2-8 through behind the fixed pulley 2-18 of correspondence position by drag-line 2-17; Also have single-chip microcomputer 2-13 and induction installation 2-14 on the described base 2-1.

For the ease of adding and discharging cleaning solution, also have inlet 2-12 and liquid outlet 2-11 on the described cavity volume 2-3, be provided with on inlet 2-12 and the liquid outlet 2-11 and be subjected to monolithic processor controlled valve 2-19.

During use, electric coagulation forceps tweezer bar is inserted in two through holes, at this moment, the induction installation in the cavity volume has been sensed the tweezer bar and has been inserted, and is about to signal and passes to single-chip microcomputer.Single-chip microcomputer is at first controlled the inlet valve open, add an amount of cleaning solution in the cavity volume after, close the valve of inlet; Next, the Single-chip Controlling machine operation, the rotation of motor is converted to horizontal movement by ball screw, ball screw is pushed ahead, namely make horizon bar and main wiping head also push ahead, simultaneously, the drag-line on the horizon bar fluffs, two interior movable pulleys of sliding tray can move under the effect of spring backward, realize two auxiliary wiping heads function of wiping backward; After motor quit work, ball screw was withdrawn backward, and at this moment, horizon bar and main wiping head be and then motion backward also, and drag-line can be spurred by horizon bar, thereby driving two movable pulleys travels forward, and realizes two auxiliary wiping heads function of wiping forward.

In this utility model, single-chip microcomputer can be controlled the work of motor repeated multiple times and stop, make ball screw repeat to travel forward and fall back backward, thereby drive two main wiping heads and two auxiliary wiping heads replace position, wiping tweezer tip, realize the cleaning function to the tweezer point.
