Description

The special-purpose visual imbibition combination of thyroid operation drag hook

Technical field

This utility model relates to a kind of department of general surgery surgical medical apparatus, and the special-purpose visual imbibition combination of specifically a kind of thyroid operation drag hook is applicable to when expanding surgical field of view in thyroid operation and uses.

Background technology

At present, department of general surgery is when implementing thyroid operation, need operative incision is drawn back, with abundant exposure surgical field of view, the method that operative incision is drawn back is: draw back operative incision from both direction with drag hook respectively by two people, and in operation process, haul all the time, the weak point of this method is: waste time and energy, inefficiency, be easy to generate fatigue, discharge operation carry out in during the blood and slime of appearance, need other oil (gas) filling device, bring many inconvenience to operation, in addition, because drag hook and operative incision contact site easily produce certain shade, but the influence apparent resolution.

Summary of the invention

The purpose of this utility model be to provide a kind of structure not only simple, use but also convenient, can not only in time discharge blood and slime in the surgical field of view, enlarge surgical field of view, drag hook is made up in the special-purpose visual imbibition of thyroid operation that also can not produce shade because of setting up the drag hook device, influence surgical field of view.

For reaching above purpose, the technical scheme that this utility model adopted is: the special-purpose visual imbibition combination of this thyroid operation drag hook, by a left side, right, a post-tensioning gib head and a corresponding left side, right, the post-tensioning neck of hook, arc elastic arm, hollow screw, width adjusting device constitutes, a left side, right, the post-tensioning neck of hook is vertically fixed on a corresponding left side respectively, right, on the upper edge of post-tensioning gib head, a left side, the left side of right drag hook head, right drag hook handle upper end is separately fixed at the two side front end of arc elastic arm, through hole is established at middle part at arc elastic arm, in through hole, be inserted with hollow screw, the upper end of the post-tensioning neck of hook is fixed on the front end of hollow screw, a left side, right, the base of post-tensioning gib head is along in a plane, on hollow screw, be provided with swivel nut, the female thread of swivel nut and the engagement of the external screw thread of hollow screw, so that when rotating swivel nut, hollow screw is moved forward or backward, thereby regulate the degree of drawing back backward of post-tensioning gib head, waist at arc elastic arm is provided with width adjusting device, to regulate a left side, the distance that right drag hook head outwards struts, it is characterized in that on the medial wall of arc elastic arm to a left side, fixedly glazing lead dimension bundle all bonds on the medial wall of right drag hook handle, the front end of fibre-optic bundle is bonded and fixed at a left side, the middle part, medial wall of right drag hook head, hollow screw is passed in the rear end of fibre-optic bundle from the bar hole of hollow screw cavity inserts in the light box of hand holding handle rear end, light in the light box reaches a left side by fibre-optic bundle, right drag hook head, thus prevent that shade from appearring in the drag hook head; Thin suction pipe on boning on the medial wall of the post-tensioning neck of hook, the front end suction inlet of thin suction pipe is bonded and fixed at the middle part of post-tensioning gib head, the cavity that hollow screw is passed in the rear end of thin suction pipe is connected with the suction ball of hand holding handle rear end, inhales ball by pinching, the blood and slime in the operation of sucking-off in time; The described left and right drag hook handle 30 degree angles that tilt to the inside, back drag hook inclination oblique 30 is forward spent angles, makes the front end of arc elastic arm and hollow screw leave operative incision by inclination left and right, the post-tensioning neck of hook; Described width adjusting device, constitute by left and right swivel nut, spiral shell axle, moving runner, the left and right end of left and right swivel nut is separately fixed at the waist of arc elastic arm two side, moving runner is fixed on the middle part of spiral shell axle, hand of spiral is opposite on the spiral shell axle of moving runner both sides, is rotated in respectively in the left and right swivel nut, so that when moving runner rotates, left and right swivel nut moves in or out simultaneously, thereby regulates the degree that struts of left and right drag hook.

The beneficial effects of the utility model are: with thyroid surgical incision is drawn back method the comparing of present use, since integrate to three directions draw back, illumination and imbibition, so left and right drag hook distance is regulated easily, the flexible control easily of back drag hook, blood and slime in the operation can be extracted out at any time, but and do not influence art open country apparent resolution, help shortening operating time, improve the operation quality.
