Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intraoperative film covering, in particular to an intestinal anastomosis operation abdominal cavity film covering structure. BACKGROUND

[0002] Intestinal anastomosis is a technique that uses an intestinal anastomosis device to reconnect the intestines after intestinal resection or intestinal trauma to restore the continuity of the digestive tract. The specific method of intestinal anastomosis depends on the condition and may involve end-to-end, end-to-side, or side-to-side anastomosis. In intestinal anastomosis, commonly used anastomosis devices include circular anastomosis devices and linear cutting anastomosis devices. Circular anastomosis devices are used for end-to-end or end-to-side anastomosis of intestinal tubes, while linear cutting anastomosis devices are mainly used for cutting and closing the rectum. Natural orifice specimen extraction surgery (NOSES) avoids the need for a specimen extraction incision on the body surface, thus offering advantages such as minimal surgical trauma, rapid postoperative recovery, good cosmetic results, and minimal psychological barriers for patients. In anorectal surgery, some instruments such as the anvil are designed to be inserted through the patient's natural orifice to reduce harm to the patient.

[0003] In summary, the current intestinal anastomosis operation process has the following technical problems: To reduce surgical trauma and allow patients to recover as quickly as possible, existing intestinal surgery often involves endoscopic surgery combined with natural orifice surgery. However, during abdominal cavity operations, the intestinal tube needs to be cut, sutured, and an anvil needs to be inserted, among other operations. During the operation process, the intestinal tube is left open in the abdominal cavity, which can lead to abdominal cavity contamination. SUMMARY

[0010] The connecting block is fixedly connected between the piece and the inner wall of the horizontal recess, and the connecting block is fixedly connected between the piece and the inner wall of the vertical recess, and the connecting block is made of elastic material;

[0011] The piece, the connecting film and the connecting block in one horizontal recess form a sealing structure at the lower side edge of the horizontal recess, and the piece, the connecting film and the connecting block in one vertical recess form a sealing structure at the lower side edge of the vertical recess;

[0012] The two pieces corresponding to the horizontal folding frame in the horizontal recess are fixedly connected with the pull wire between the horizontal folding frame, and the two pieces corresponding to the vertical folding frame in the vertical recess are fixedly connected with the pull wire between the vertical folding frame.

[0013] Further, one horizontal branch pipe is fixedly connected to the upper side of one horizontal recess, and the horizontal branch pipes connected with a plurality of horizontal recesses are fixedly connected with a horizontal lower pipe on one side, and the horizontal lower pipe is fixedly connected with a horizontal main pipe at one end upward;

The storage ball is located in the direction of the upper membrane close to the lower membrane. The storage ball is three-quarter spherical and has a storage groove at the upper membrane position.

[0020] Furthermore, the four corners of the fixed frame are fixedly connected with side rings.

[0021] Beneficial effects of the present invention:

[0022] A peritoneal membrane covering structure for intestinal anastomosis surgery has an overall structure similar to the bubble paper in the prior art. Before use, the internal gas is evacuated by connecting the syringe to the external joint, and the horizontal branch and vertical branch of the bellows structure are pulled into the corresponding horizontal recesses and vertical recesses. The horizontal folding frame shrinks due to the proximity of the horizontal recesses, and the vertical folding frame shrinks due to the proximity of the vertical recesses. After the overall shrinkage, the upper membrane, the lower membrane and the fixed frame are curled up as a whole, and the patient's abdominal cavity is entered through a laparoscope. Before cutting the intestinal tract, air is inflated through the external tube to extend the horizontal branch and vertical branch of the bellows structure, and the horizontal recesses and the vertical recesses are moved away from each other. At the same time, the horizontal folding frame and the vertical folding frame are unfolded to achieve the purpose of unfolding the lower membrane, the upper membrane and the fixed frame. During the unfolding of the horizontal folding frame and the vertical folding frame, the pull wire of the negative pressure component will be pulled, so that the pull wire connection The connected segments are pulled up, and negative pressure is formed at the peritoneal position where the segments are located through the connecting membrane, so that the lower membrane is attached to the peritoneum and the position where the surgeon unfolds it. The unfolding effect is achieved through inflation, and at the same time, a prominent effect of adsorption is achieved at the covered position. An intestinal incision is performed on the upper side of the upper membrane to take over the contamination of the intestinal tract. After the operation, the gas is evacuated, the horizontal folding frame and the vertical folding frame are folded together, and the contamination is deposited in the storage tank by gravity, while the folds of the upper membrane gradually cover the upper side of the storage ball. Therefore, while the folding effect is achieved through evacuation, a prominent effect of shielding the contamination is achieved. Subsequently, the surgeon controls the fixed frame through the side ring to drive the upper and lower membranes to be retracted as a whole, and pulls them through the laparoscope to reduce contamination; or performs in-and-out operations through the natural cavity of the anus to reduce contamination caused by long-term operations other than cutting and closing the intestinal tract.

[0023] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
