Description of the Invention: [Technical Field] The present invention relates to a surgical instrument, and more particularly to a wound protector suitable for use in a peritoneal cavity: surgery. [Prior Art] As shown in Figs. 1 and 2, a conventional wound protector 10 for laparoscopic surgery is made of a flexible material, has a hollow capsule 12 forming a chamber u around an axis, and is fixed separately. A bottom positioning portion 13 and a top positioning portion 14 of the hollow capsule 12. In use, firstly make a mouth 21 in a patient's abdomen, then insert the bottom positioning portion 13. into the incision 21, and then pull the wound protector 1 to the top, with the patient's abdomen 2〇 The tissue is convergent, the bottom positioning 邛 13 will be placed in the patient's abdomen 2 ,, after which the top positioning portion μ is rolled toward the bottom end until it approaches the patient's abdomen 2 〇, and finally the operation can be performed An instrument (not shown) extends through the chamber u and into the abdomen of the patient to perform a surgical procedure. Although the wound protector 10 has the above-mentioned functions of use, it still has the following disadvantages: 1. Since the tissue of each patient's abdomen 20 has different thickness and thickness, it often occurs that the top positioning portion 14 completes the retraction and the patient's abdomen 2 There is still a gap t between the crucibles. In addition, the wound protector 1 has a flexible state, so that the bottom positioning portion 13 is pulled outwardly with a relatively small force and the card is not effective. The wound protector 10 is not robust enough and is highly likely to affect the disadvantages of the surgical procedure. 201102044 § Top position. The winding of the crucible 14 is time consuming, resulting in a long installation time of the wound protector 1, which does not meet the requirements of the surgery. To insert the bottom positioning portion 13 into the slit 21, the operator must pinch the bottom portion 13 to reduce the deformation and then plug the person to cut the α 21, and the wound protection $ 1G is contaminated. The disadvantages of wound infection are more than two. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a method for improving the firmness of the wearer to shorten the time for women's wear and to reduce the risk of contamination. Thus, the wound protector of the present invention is suitable for use in a laparoscopic surgery comprising a body member and a first fixing member.

The notch 415 of the first base 41 is pushed, and the second base is pushed toward the first base 41 until the first cover 42 is touched, and then the second base 61 is rotated, so that the locking block 616 is respectively When the card slot 416 is inserted, the second base 61 and the first base 41 can be coupled to each other, and the opening ring 615 abuts against the inner ring surface 322 of the hollow capsule 32, thereby preventing the The tissue of the patient's abdomen 8 收 can be bundled to open the incision 81, as shown in FIG. 10, and then different surgical instruments 9 such as the air inlet tube 91 or the laparoscope 92 can be inserted into the insertion hole 723 of the connection port 70. And entering the patient's abdomen 8〇 through the anti-reverse structure 724 (elastic piece) and the chamber 31, the elastic piece can be closely attached to the air inlet f 91, the laparoscope 92 to prevent the patient's abdomen 8G from being poured. The inside of the gas leaks, the scalpel is inserted into the socket 723 of the other connection port 70 and the check structure 724 (film) is cut through the chamber. 31, entering the patient's abdomen 80 β ' can be adhered to the scalpel 93 by the film to prevent gas leakage, and the surgical operation space can be formed by injecting gas into the abdomen 80 of the patient to expand the patient's abdomen 80. By using the laparoscopic % with the video system (not shown), the patient's abdomen can be seen in the 6th (4th) condition. The scalpel 93 can (4) malignant tissue and sampling. When the laparoscopic surgery is completed, the aforementioned surgery (4) 9G is sequentially performed. The wound protector of the present invention can be pulled out of the incision 81 and finally treated as a medical waste. In summary, the above-described wound protector of the present invention has the following advantages and advantages, and indeed achieves the object of the invention: 1. Since the present invention can be placed in the abdomen 80 of the patient by the bottom positioning body 33, The first fixing member 4 that is in a hard state generates an external pulling force on the bottom positioning body 33 by the self-weight sitting on the patient's abdomen 80 and folds the top positioning body 34 of the body member 30 outward. The tensioning card is disposed in the positioning groove 422 of the first fixing member 40, and generates another external pulling force on the bottom positioning body 33. Further, the first fixing member 4〇 does not remain between the first fixing member 4〇 and the patient's abdomen 8〇. There is a gap, so that the present invention has the effect and advantages of improving the firming effect for the operation. Second, because the present invention does not need to retract the hollow capsule 32, the present invention has the same function as the conventional wound protector 1 Shorten the installation time to meet the efficacy and advantages of the surgery. 2. Since the present invention can be inserted into the chamber 31 and sandwich the two holding blocks 36, and then insert the bottom of the hollow capsule 32 into the slit 81, the invention can be reduced. The object is contaminated and can reduce the effectiveness and advantages of wound infection. The above is only the preferred embodiment of the present invention, and the scope of the invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are All remain within the scope of the invention patent.
