Technical field

This utility model relates to the large-scale elastic separating plier of a kind of direct-view, is used for the interior large-scale organ-tissue of human body and draws and free operation, belongs to medical instruments field.

Background technology

In the human body body in the laparoscopic surgery, need draw and dissociate large-scale organ-tissue in the body, be convenient to operative site the operation that undergos surgery of enough spaces is arranged, prior art does not have special-purpose apparatus forceps class, substitute with general instruments pincers class, its defective is: general instruments pincers class pliers head clip tooth is sharp, no arc binding clip and the design of noinvasive flute profile, large-scale organ-tissue draw and free process in easily cause organ-tissue damage, do not satisfy ideal surgical effect.

The utility model content

The technical problems to be solved in the utility model overcomes above shortcomings in the existing structure exactly, and provides a kind of reasonable in design, operation to use convenient, effective, the safe large-scale elastic separating plier of direct-view.

The technical scheme in the invention for solving the above technical problem is: the large-scale elastic separating plier of a kind of direct-view comprises fixed handle, flexible handle, claw beam, clamp seat, pull bar, connecting plate, clamp, runner, ball cover, pitman coupling, adapter sleeve and rotaring wheeling sleeve; Fixed handle and flexible handle are rotationally connected; The clamp seat is fixed on the claw beam; Connecting plate is rotatably connected in clamp seat and the pitman coupling; Clamp is fixed on the connecting plate; Pull bar one end is fixed with pitman coupling, and the other end is connected on the flexible handle; Adapter sleeve is fixed on the fixed handle; Rotaring wheeling sleeve is fixedlyed connected with claw beam with runner respectively; The ball cover is sleeved on outside the rotaring wheeling sleeve, and is fixed on the adapter sleeve; It is characterized in that: described clamp is curved, has corrugated folder tooth on it.

This utility model is equipped with limit base on described flexible handle.

This utility model has electricity and coagulates installing hole on described fixed handle.

This utility model compared with prior art has following advantage and effect: 1, reasonable in design; 2, clamp is curved, and the folder tooth is a waveform, belongs to the noinvasive flute profile, can never damage organ-tissue in operation traction and free the extracting in moving, and grasps traction and free effective, and convenient, safety are used in operation.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment.

Embodiment:

Referring to Fig. 1～Fig. 3, this utility model embodiment comprises that fixed handle 1, flexible handle 2, hold-down screw 3, claw beam 4, clamp seat 5, pull bar 6, runner 7, rotaring wheeling sleeve 8, roller 9, ball cover 10, adapter sleeve 11, drag link sleeve 12, fixed cover 13, draw-bar seat 14, pull rod slot 15, limit base 16, flushing hole 17, flushing port lid 18, clamp 19, clamp connecting pin 20, connecting plate connecting pin 21, connecting plate 22, link pin 23, folder tooth 24, pitman coupling 25, electricity coagulate installing hole 26.

Fixed handle 1 and flexible handle 2 usefulness hold-down screws 3 are rotationally connected.Pull rod slot 15 is opened on flexible handle 2.Limit base 16 is installed on the flexible handle 2.Electricity coagulates installing hole 26 and opens on fixed handle 1.

Claw beam 4 is fixing with runner 7 welding.Rotaring wheeling sleeve 8 is equipped with two rollers 9, and fixed cover 13 is filled in the rotaring wheeling sleeve 8.Ball cover 10 is fixedly set on the rotaring wheeling sleeve 8, and is sleeved on outside roller 9 and the adapter sleeve 11.Drag link sleeve 12 is filled in the adapter sleeve 11.Fixed handle 1 is fixedly set on the adapter sleeve 11.Drag link sleeve 12 is fixedly set on the adapter sleeve 11.Rotaring wheeling sleeve 8 is fixing with runner 7 and claw beam 4.Runner 7 and rotaring wheeling sleeve 8 and fixing with runner 7 welding are passed in flushing hole 17, and flushing port lid 18 is connected and fixed with flushing hole 17.

Have folder tooth 24 on the clamp 19, folder tooth 24 is a waveform.One end of two clamps 19 crosses one another, and is rotatably connected on the clamp seat 5 with clamp connecting pin 20 at infall.The bottom of clamp 19 is fixed on the connecting plate 22 with connecting plate connecting pin 21.Connecting plate 22 usefulness link pins 23 are rotatably connected on an end of pitman coupling 25, and the end welding of the other end of pitman coupling 25 and pull bar 6 is fixing, and the other end of pull bar 6 has draw-bar seat 14.
