Abstract

The utility model relates to an automatic dilator for operative incisions at armpit positions at both wings, which can effectively solve the problem of automatically dilating the operative incisions at armpit positions at both wings. The technical scheme is that the automatic dilator for operative incisions at armpit positions at both wings comprises an arched elastic piece. L-shaped connecting pieces are symmetrically connected at both ends of the arched elastic piece. Leafy drag hooks with inward curved surfaces are installed on the L-shaped connecting pieces. The automatic dilator for operative incisions at armpit positions at both wings provided by the utility model has a simple structure and is convenient to use, and can dilate the operative incision automatically so as to expose the operative area optimally, alleviate the labor intensity of doctor, lower the operative difficulty, reduce the wound of tissues and shorten the operation time.

Description

The automatic dilator of two wing axillary fossa position operative incisions

Technical field

This utility model relates to and is carrying out the automatic dilator of a kind of two wing axillary fossa position operative incisions that axillary fossa position when operation can strut armpit incision automatically.

Background technology

When carrying out the operation of axillary fossa position, because of the narrow and small difficult exposure of operative region, often need to use two artificial drag hooks that otch is drawn back, but cause personnel's erect-position crowded, the influence operation is carried out.Therefore; Developing a kind of purpose is to overcome the deficiency that prior art exists and provides a kind of and can automatically operative incision be strutted; Automatically appear operative region; Alleviate doctor's labor intensity, reduce operating difficulty, the apparatus that two wing axillary fossa position operative incisions of shortening operating time strut automatically is imperative.

Summary of the invention

To above-mentioned situation, for overcoming the defective of prior art, the purpose of this utility model just provides the automatic dilator of a kind of two wing axillary fossa position operative incisions, can effectively solve the problem that two wing axillary fossa position operative incisions strut automatically.

The technical scheme that this utility model solves is, comprises bow-shaped shrapnel, and the two ends symmetry of bow-shaped shrapnel is equipped with L type brace, and the inside lobate drag hook of curved surface is housed on the L type brace.

The utlity model has simple in structurely, easy to use, can automatically operative incision be strutted, reach the best and appear operative region, alleviate doctor's labor intensity, reduce operating difficulty, reduce tissue injury, shorten the advantage of operating time.

Description of drawings

Fig. 1 is this utility model structural front view.

Fig. 2 is the three-dimensional structure diagram of this utility model.

The specific embodiment

Be described further below in conjunction with the specific embodiment of accompanying drawing this utility model.

As shown in Figure 1, this utility model comprises bow-shaped shrapnel, and the two ends symmetry of bow-shaped shrapnel 1 is equipped with L type brace 2, and the inside lobate drag hook 3 of curved surface is housed on the L type brace 2.

Described bow-shaped shrapnel is linked to each other by the end of first movable axis 4 with L type brace; Lobate drag hook is linked to each other by the other end of second movable axis 5 with L type brace; Constitute movable connection structure; With the position of random adjustment bow-shaped shrapnel and the lobate drag hook of adjustment automatically strut direction and angle, reach operative incision the best and appear effect;

Described lobate drag hook 3 is 3 leaves or 5 lobate, to increase the frictional force with incision tissue, guarantees the stability between drag hook and the otch; Described dilator can adopt rustless steel to process when making.

When this utility model uses in operation; Symmetric two lobate drag hooks place the operative incision both sides; The elastic force that utilizes bow-shaped shrapnel to produce automatically springs open operative incision to both sides; Simultaneously since between bow-shaped shrapnel and the drag hook for flexibly connecting, so can arbitrarily adjust the position of bow-shaped shrapnel with adjust lobate drag hook automatically strut direction and angle, reach operative incision the best and appear effect.

Show that by above-mentioned situation this utility model efficiently solves originally when carrying out the operation of axillary fossa position,, often need to use two artificial drag hooks that otch is drawn back because of the narrow and small difficult exposure of operative region; But cause personnel's erect-position crowded, and the problem that the influence operation is carried out, not only easy to use; Can automatically operative incision be strutted, reach the best and appear operative region, and effectively alleviate doctor's labor intensity; Reduce operating difficulty, reduce tissue injury, shorten operating time; Improving surgical effect, alleviate less patient suffering, is the innovation on two wing axillary fossa position operating theater instruments.
