Description

Exposure support device for human surgical cavity

Technical field

The invention discloses a human intraoperative in-vivo exposure support device, relating to a surgical medical device, which can be widely used for medical instruments for expanding a human surgical region.

Background technique

At present, laparoscopic surgery has been widely carried out in clinical practice. Compared with traditional open surgery, it has the advantage of minimally invasive, but also because of the small incision, which makes many surgical fields insufficiently exposed, which brings inconvenience to the operation. At present, in the laparoscopic surgery, the traction of the tissue in the surgical area is difficult to expose, and it can only be distracted from the limited angle.

In order to solve the problem of difficulty in visual field exposure of laparoscopic surgery, the patent number is CN201110004171.8 "Inflatable handcuff hook for minimally invasive surgery", by installing an inflatable handle made of soft material without inflation on the check valve housing. It is placed into the patient's lumen from the sheath, and the rear of the check valve is left outside the sheath, and the high-pressure gas is pressed into the inflatable hand target from the air inlet of the check valve, and the inflated hand target opens the patient's lumen to form A high-pressure support, which in turn presses and opens a large number of internal organs. The drawback of this patent is that in actual operation, the inflatable body exposure device is not only bulky, there is a dead angle of the surgical field of view, affecting the operation; and it is impossible to accurately and openly expose and expose the target surgical field, and the inflatable handcuff hook structure is complicated. It contains many parts and components, and needs to be disassembled during operation, which is easy to fall into the abdominal cavity of the patient and delay the operation.

The patent number is CN201220454372.8, "the hook for laparoscopic surgery", and the first hook and the second hook which are connected by a plurality of loops are arranged, and a large-area pulling head is formed in the abdominal cavity, and the action area is large. The drawback of this patent is that the hooking operation is complicated and requires puncture on the abdominal wall to the abdominal wall. The damage is large, and it is impossible to accurately and accurately open and expose the target area of the operation.

Therefore, it is necessary to design a new product to meet the actual needs of use, to facilitate the operation of doctors, and to reduce the pain and injury of the operator.
