Abstract

The invention relates to microsurgical point-spreading forceps, comprising a left part and a right part. The left part and the right part intersect and are connected via a hinge. The tips of the left and right parts are provided with arc traction hooks bent out, respectively. The inner sides of handles are provided with rotary screws, respectively. The screws on the left part and the right part are connected through adjusting nuts. During using, by rotating the adjusting nuts, the screws on the left and right parts are driven to extend out at the same time, the handles are spread out, and the tips are also driven to spread out via hinging connection. A wound is exposed by spreading of jaws, when open, the jaws cause little tissue injury, the opening size is convenient to control, adjusting is convenient, safe and reliable, and surgical time is thus shortened.

Description

A kind of microsurgery point-like distraction forcep
Technical field
The present invention relates to medical instruments field, refer in particular to a kind of microsurgery point-like distraction forcep.
Background technology
During present brothers' microsurgery, for exposing wound surface, obtaining roomy surgical field of view, usually edge of wound skin and distance being rectified normal skin closure tractive and fix, expose wound surface; When sewing up fixing under naked eyes, the subcutaneous superficial vein damage of suture dissection to edge of wound is heavier, and minimizing can supply vein anastomosis, causes postoperative backflow obstacle, even operative failure; And to rectify normal skin closure with distance be also a kind of damage; Sometimes expose and need not again to sew up tractive, waste operating time; And exposure excessively easily causes vascular suture overtension or cannot directly sew up, again sew up fixing after needing dermal sutures out, increase operating time, for this reason, we have developed a kind of microsurgery point-like distraction forcep, open exposure wound surface by jaw, and little to tissue injury when jaw opens, size conveniently to control, easy to adjust, safe and reliable, thus save operating time.
Summary of the invention
The present invention seeks to provide a kind of microsurgery point-like distraction forcep to overcome the deficiencies in the prior art, exposure wound surface is opened by jaw, and jaw is little to tissue injury when opening, size conveniently controls, easy to adjust, safe and reliable, thus save operating time.
For achieving the above object, the technical solution used in the present invention is: a kind of microsurgery point-like distraction forcep, comprises left caliper, right caliper body; Described left caliper and right caliper body intersect to be placed and chain connection; The pincers point place of described left caliper and right caliper body is respectively arranged with the traction of bandy arc and hooks, and is respectively arranged with rotating leading screw inside clamp handle; Described left caliper is connected by adjusting nut with the leading screw on right caliper body; During work, rotate described adjusting nut and drive the leading screw on left caliper and right caliper body simultaneously protruding, clamp handle is outwards opened be connected through the hinge to drive pincers point also outwards to open.
Preferably, the leading screw on described left caliper and right caliper body is respectively near the junction of left caliper and right caliper body.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Microsurgery point-like distraction forcep of the present invention opens exposure wound surface by jaw, and little to tissue injury when jaw opens, size conveniently to control, easy to adjust, safe and reliable, thus save operating time.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation of microsurgery point-like distraction forcep of the present invention;
Wherein: 1, left caliper; 2, right caliper body; 3, pincers point; 4, clamp handle; 5, leading screw; 6, adjusting nut.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
Accompanying drawing 1 is microsurgery point-like distraction forcep of the present invention, comprises left caliper 1, right caliper body 2; Described left caliper 1 and right caliper body 2 intersect to be placed and chain connection; Pincers point 3 places of described left caliper 1 and right caliper body 2 are respectively arranged with the traction of bandy arc and hook, and are convenient to open exposure wound surface; Rotating leading screw 5 is respectively arranged with near hinge connection inside the clamp handle 4 of described left caliper 1 and right caliper body 2; Described left caliper 1 is connected by adjusting nut 6 with the leading screw 5 on right caliper body 2; During work, rotate described adjusting nut 6 and drive the leading screw 5 on left caliper 1 and right caliper body 2 simultaneously protruding, clamp handle 4 is outwards opened be connected through the hinge to drive pincers point 3 also outwards to open, expose wound surface, be convenient to operation.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Microsurgery point-like distraction forcep of the present invention opens exposure wound surface by jaw, and little to tissue injury when jaw opens, size conveniently to control, easy to adjust, safe and reliable, thus save operating time.
Below be only embody rule example of the present invention, protection scope of the present invention is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, all drops within rights protection scope of the present invention.
