Description

An incision retraction fixation device

technical field

The utility model relates to the technical field of medical instruments, in particular to an incision retracting and fixing device.

Background technique

With the development of thoracoscopic equipment and technology, thoracoscopic surgery has been widely used in the diagnosis and treatment of chest diseases. During thoracic surgery, it is necessary to cut an incision on the patient's body for the insertion of instruments. The frequently used instrument is the lens. Using the lens to observe the internal situation and guide the surgical operation, the impact of the lens on the operation is very important. At present, hospitals generally use laparoscopic protective sleeves to protect endoscopic equipment. This protective sleeve can protect tissues from direct extrusion of endoscopic operating equipment, and can provide a relatively stable moving space for endoscopic operations. Laparoscopic protective sleeves currently in use. The lower part is put into the corresponding body cavity. Then by turning it over, it is fixed.

In addition, in the use of various laparoscopes, some of them are not operated by punching holes, but by small incisions to complete their functions. In this mode, a disposable incision retractor will be used, and on this basis, various endoscopic equipment will be operated in the space provided by it. Even, for general surgery, there are larger models that can provide a wider range of incision traction functions. However, in the actual operation, it is often difficult to ensure the stability of the mirror holding, and the lens shakes easily, and sometimes even causes the endoscope to slip and cause damage to tissues and organs. Balance, and then cooperate with the attending physician to complete the operation. This not only requires a lot of manpower, but sometimes the position cannot meet the requirements of the chief surgeon and needs to be adjusted repeatedly.

In summary, there are the following problems in the existing technology:

1. The position of the operating rod of the endoscope is unbalanced and easy to fall off, which will cause injury to the patient;

2. During laparoscopic surgery, the surgical area of the patient is often directly squeezed by the laparoscopic operating equipment.

Chinese patent application: CN207768521U discloses a notch protective cover for preventing lens pollution, including a protective cover body, the protective cover body is composed of a notch protective cover and a lens protective cover, and the notch protective cover is set at the notch, along the length direction of the notch protective cover A limit baffle and an elastic rubber ring are respectively provided on both sides of the two sides, and a lens protective cover is provided on the side of the limit baffle far away from the elastic rubber ring. The length of the protective cover in the horizontal direction is greater than that of the notch protective cover. The lens protective cover can pass through the limit baffle and extend from one end of the notch protective cover, and the other end protrudes. The lens protective cover is trumpet-shaped. The notch protective cover and the lens protective cover A semi-closed cavity is formed between them, but this patent can only play the role of protecting the laparoscope, and the problems of the laparoscopic lens shaking and the scalpel falling off are still unsolved.

Chinese patent application: CN106308893A discloses a single-port thoracoscopic operating system suitable for artificial pneumothorax, including an incision retractor and a single-port thoracoscopic operating platform. The operating platform for single-hole thoracoscopic surgery is connected with the outer clasp of the incision retractor fixer through a sealing fixture. The incision retractor fixer includes: an elastic inner snap ring, an elastic outer snap ring and a connecting pipe body, which are integrated. The operating platform for single-hole thoracoscopic surgery includes an operating platform and a sealing and fixing device, and a plurality of surgical instrument channels and an inflation/exhaust three-way valve are arranged on the operating platform. But this patent still can't solve the problem that the laparoscopic lens shakes and the scalpel is easy to fall off.

Therefore, in view of the above problems, the inventor of the present utility model has constructed a protective cover capable of realizing self-positioning. The utility model can complete the fixing of the operating tool according to the will of the chief surgeon when needed.
