Description

Direct-view pawl nipper

Technical field

This utility model relates to a kind of direct-view pawl nipper, and it mainly is that human internal organs is socketed, and belongs to the medical device technology mechanical field.

Background technology

Traditional surgical operation generally all will cut 6～15 centimeters or longer otch together on patient's skin and flesh, in operation process, focus needs excision, behind resection operation, intracorporeal organ need socket stitching, and prior art is to carry out pneumoperitoneum in the human body body, makes operation that certain space be arranged, socket stitching with the general surgery pincers, its defective is as with pneumoperitoneum operation, and operating time is long, and it is slow that patient feels bad wound healing, if the patient body weakness, wound healing effect is just poorer; Socket stitching with general surgery pincers, clamps insecurely, ideal surgical effect is not satisfied in easy landing.

The utility model content

Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in the prior art, and a kind of reasonable in design is provided, and otch is little during operation, the direct-view pawl nipper that sewing effect is good.

This utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of direct-view pawl nipper, comprise fixed handle, flexible handle, clamp, claw beam and pull bar, fixed handle is connected with flexible handle, it is characterized in that: it also comprises runner, claw beam seat, runner shaft, runner axle sleeve, fixing head, fixed cover, bearing, draw-bar seat, binding clip seat, connecting plate, insulation sleeve and rotary sleeve; Be with insulation sleeve on the described claw beam, claw beam and runner are fixed; The claw beam cover for seat is gone into claw beam and is tightened with runner; Rotary sleeve penetrates runner and is connected with claw beam; Runner shaft is inserted in rotary sleeve; Bearing is inserted in runner shaft, and bearing and runner coincide and tighten; Fixing head is inserted in runner shaft and fixing with the runner gummed; The runner shaft cover is inserted in runner shaft and fixes by fixed cover; Fixed cover snaps in fixed handle; All have clamp pawl and pliers head clip tooth on two clamps, clamp pawl and pliers head clip tooth match each other; Two clamps are fixed on the binding clip seat; Binding clip seat and claw beam welding are fixing; One end of two connecting plates is connected to the end of two clamps, and the other end is connected on the pull bar; Pull bar passes claw beam, runner, rotary sleeve and fixed handle, is connected with flexible handle.

The profile of tooth of clamp pawl described in the utility model is down card.

This utility model compared with prior art, has following positive effect: reasonable in design, otch is little during operation, only need to cut 2-3 centimetre, re-use special-purpose drag hook otch is stretched, the cold light source light beam is focused in the human body by light guide bundles, both can make operative doctor clearly directly see each position in the body clearly, and lowered infected danger again because of otch is little, reached good surgical effect.
