Abstract

The utility model relates to a jaw-type surgical pull hook which is mainly composed of handles (2), (5), a rack bar (1), a ratchet (6), and hook plates (3), (4). The utility model adopts the structure of the plate-shaped pull hooks and the up-down rack bar and ratchets; thus, the handles can be operated independently; the utility model solves the problem that the existing pull hooks can only be used for abdominal walls but discharging pad intestinal canals, operation field is not clear, and other organs are easy to damage. Compared with the existing pull hooks, the utility model has the advantages of clear operation field, stabilization, safe operation, high speed, convenience, automatic positioning, one-man operation, etc. The utility model is especially used for abdominal transverse incision operations and longitudinal incision operations.

Description

Pliers-type surgical drag hook

This utility model relates to a kind of medical operation apparatus, particularly a kind of abdominal operation otch drag hook.

At present, owing to the improvement to traditional surgical approaches, the operation of abdominal part cross sections is more and more general, the Shang Wuyu supporting surgery tractor of should performing the operation still adopts old-fashioned drag hook clinically but up to now,, because its drag hook is structure of steel wire, intestinal tube is easily outer in operation emits, its localization part employing gullet plate, two handles are inseparable during operation, need several assistants to cooperate and could perform the operation troublesome poeration, other organ of easy damaged, the surgical field of view susceptible to, operating time is longer, and patient is painful big.

The purpose of this utility model is to provide a kind of can fully expose surgical field of view, one man operation, releasable jaw type surgery tractor quickly and easily.

The purpose of this utility model realizes by the outer clamp type structure of opening, mainly by handle, locatees ratchet, drag hook is formed, it is characterized in that its drag hook adopts plank frame, the shape of drag hook plate can change as required, and the location ratchet adopts releasable tooth bar, ratchet structure up and down.During operation, push two hook plates aside with hands, its first transaction of a day's business position is just fixing automatically by the effect of ratchet, and surgical field of view is fully exposed.

Because this drag hook has adopted board-like drag hook and ratchet tooth bar self positioning structure up and down, this utility model is compared with existing drag hook, have the surgical field of view of exposure fully, stablize, handling safety, fast, conveniently, two handles can separate the characteristics of independent operation, it is simple in structure, is convenient to sterilization.

Below in conjunction with drawings and Examples this utility model is described further.

Fig. 1 is the overall package figure of this utility model.

Fig. 2 is the component diagram of this utility model.

Fig. 3 is the deformation pattern of this utility model.

As shown in Figure 1: 2 is left handle, and 1 for welding the ratchet tooth bar of tying or adopting other method to be fixed together with

left handle

2, and 3 is Zola's hook plate, and 4 is right drag hook plate, and 5 is right handles.In Fig. 2,6 for being fixed on the location ratchet on the right handles, and 7 is the circular protruding axle on the

left handle

2, and 8 is the groove that matches with 7 on the right handles 5.In use, can push incision of abdominal wall aside with the drag hook plate respectively, upwards row fills up intestinal tube, downward row's pad bladder, and to

last pincers axle

7,8, under the effect of ratchet, the spreading angle of pincers has just been fixed so then, clamps axle and keep stable under the thrust of incision of abdominal wall and intestinal tube.The end of the top of left and right sides

drag hook plate

3,4 and left and

right handle

2,5 can make two drag hook plates parallel when operation with screw 9,10 hinge knots together like this, is not subjected to the influence of vice body spreading angle.In the specific implementation,

drag hook plate

3,4 can also be welded on respectively on the left and

right handle

2,5, the size shape of

drag hook plate

3,4 can be adjusted according to different needs.For example: the drag hook plate can be made semicircle, is used for vagina operation, as shown in Figure 3.The pincers shaft portion also can change convexo-concave 7,8 parts into the plug-in type of axis hole or fixing axis structure.

This utility model is equally applicable to the abdominal surgery of other different incisions.

Claims
