Description

Technical Field

[0001] This utility model relates to medical device technology, specifically to an incision sealing device for laparoscopic surgery. Background Technology

[0002] Laparoscopic surgery is an advanced minimally invasive surgical technique that uses a laparoscope—a medical device equipped with a miniature camera—and a series of precise surgical instruments to enter the abdominal cavity through a small incision. Under the real-time monitoring of a high-definition camera system, doctors can clearly observe the organs and tissue structures within the abdominal cavity and perform surgical procedures with precision, thereby enabling the diagnosis and treatment of diseases.

[0003] Current laparoscopic surgery requires at least three holes to be made in the abdomen: one for observation and two for operation. After the instrument is inserted, air needs to be injected into the abdominal cavity. The gap between the instrument and the holes can cause air leakage. Therefore, the holes need to be partially sutured to create a sealed environment in the abdominal cavity. However, suturing the holes with sutures wastes a lot of surgical time, and if the sutures are not tight enough, the gas in the abdominal cavity will slowly leak out, causing unstable air pressure in the abdominal cavity. Utility Model Content

[0004] The purpose of this invention is to provide an incision sealing device for laparoscopic surgery to address the shortcomings of existing technologies where air leaks through the incision during laparoscopic surgery.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a laparoscopic surgical incision sealing device, comprising an external balloon;

[0006] A connecting airbag is fixedly installed at the bottom of the outer airbag, and the connecting airbag is connected to the inner cavity of the outer airbag.

[0007] An inner airbag is fixedly installed at the bottom of a connecting airbag, and the inner cavity of the inner airbag is connected to the inner cavity of the connecting airbag.

[0008] A connecting tube is fixedly installed on one side of the outer airbag, and the connecting tube passes through the outer airbag and the inner airbag in sequence and extends to the outside of the inner airbag.

[0009] An air injection tube is fixedly installed on one side of the external airbag, and the air injection tube is connected to the inner cavity of the external airbag.

[0010] An expansion block is fitted onto the outside of the connecting tube, and the expansion block is located inside the connecting airbag.

[0011] Two valves are fixedly installed on the inner end of the connecting pipe.

[0012] Furthermore, the outer airbag is smaller than the inner airbag.

[0013] Furthermore, the connecting airbag is elliptical in shape.

[0014] Furthermore, the expansion block is elliptical.

[0015] Furthermore, the connecting pipe is a flexible tube.

[0016] Compared with the prior art, the present invention provides a laparoscopic surgical incision sealing device. An inner balloon is inserted into the patient's abdominal cavity through the abdominal opening, a connecting balloon remains at the abdominal opening, and an outer balloon is positioned outside the abdominal cavity. Air is injected into the inflator tube through the trachea. The outer balloon, connecting balloon, and inner balloon gradually inflate. The operating instrument is then inserted into the abdominal cavity through the connecting tube. Air continues to be injected into the trachea until the outer balloon, connecting balloon, and inner balloon inflate completely to fit the abdominal opening. The connecting tube and the operating instrument are then in contact. When air is injected into the abdominal cavity to separate the skin and organs, the injected gas will not leak out of the body. When it is necessary to temporarily remove the instrument from the body, a valve will seal the connecting tube. Attached Figure Description

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] Example 1:

[0026] Please see Figures 1-4 A laparoscopic surgical incision sealing device, comprising an external balloon 1;

[0027] Connecting airbag 2 is fixedly installed at the bottom of outer airbag 1, and connecting airbag 2 is connected to the inner cavity of outer airbag 1;

[0028] The inner airbag 3 is fixedly installed at the bottom of the connecting airbag 2, and the inner cavity of the inner airbag 3 is connected to the inner cavity of the connecting airbag 2.

[0029] The connecting tube 4 is fixedly installed on one side of the outer airbag 1. The connecting tube 4 passes through the outer airbag 1 and the inner airbag 3 in sequence and extends to the outside of the inner airbag 3.

[0030] Inflation tube 5 is fixedly installed on one side of external airbag 1 and is connected to the inner cavity of external airbag 1.

[0031] Expansion block 6 is sleeved on the outside of connecting tube 4 and located inside connecting airbag 2;

[0032] Two valves 7 are fixedly installed on the inner end of the connecting pipe 4.

[0033] The specific implementation method is as follows: The sealing device is generally H-shaped. The outer airbag 1 is a medical airbag, which is elliptical in shape. The top dimension of the outer airbag 1 is larger than the bottom dimension. The outer airbag 1 is wider at the top and narrower at the bottom. The outer airbag 1 has a hollow structure and is partially outside the patient's body during use. The connecting airbag 2 is entirely located at the opening in the patient's abdomen. The connecting airbag 2 is a medical airbag. An expansion block 6 is provided inside the connecting airbag 2. The expansion block 6 is an elliptical medical rubber block. The expansion block 6 is fixedly connected to the connecting tube 4. The inner airbag 3 is narrower at the top and wider at the bottom. The inner airbag 3 has a hollow structure. The inner cavities of the outer airbag 1, the connecting airbag 2, and the inner airbag 3 are connected. The top end of the connecting tube 4 is fixedly connected to the outer airbag 1. The bottom end of the connecting tube 4 is fixedly connected to the inner air bladder 3. The air injection tube 5 is a hollow tube and is connected to the inner cavity of the outer air bladder 1. By injecting air into the air injection tube 5, the outer air bladder 1, the connecting air bladder 2 and the inner air bladder 3 expand, squeezing and sealing the opening in the patient's abdomen. A valve 7 is fixedly installed at the top and bottom of the inner cavity of the connecting tube 4. After the valve 7 is inflated in the abdominal cavity, if the laparoscope lens is contaminated with blood or other body fluids that obstruct observation, the laparoscope needs to be withdrawn from the body for cleaning. When the laparoscope is withdrawn, the valve 7 closes under the action of intra-abdominal pressure, and the air in the abdominal cavity will not leak out of the body. The valve 7 has a central fan-shaped structure and the surface of the valve 7 is inclined.

[0034] The size of the outer airbag 1 is smaller than the size of the inner airbag 3.

[0035] The connecting airbag 2 is oval in shape.

[0036] Expansion block 6 is elliptical.

[0037] Connecting pipe 4 is a flexible tube.

[0038] Working principle: During use, the doctor makes an incision in the patient's abdomen, then inserts the inner balloon 3 into the patient's abdominal cavity. At this time, the connecting balloon 2 is at the opening in the patient's abdomen, and the outer balloon 1 is outside the patient's body. Air is injected into the inflation tube 5, and the outer balloon 1, connecting balloon 2, and inner balloon 3 inflate, opening the patient's abdominal opening. Surgical instruments are then inserted into the patient's body through the connecting tube 4. Air continues to be injected into the inflation tube 5, and the inflated balloons compress the connecting tube 4, sealing it between the connecting tube 4 and the examination instruments. 3. The inner side of the patient's abdomen is squeezed, the outer balloon 1 is squeezed, the connecting balloon 2 is squeezed and sealed at the opening of the patient's abdomen, thus isolating the patient's abdominal cavity from the outside world. The air injected into the patient's abdominal cavity remains in the patient's abdominal cavity. After the examination and surgery are completed, the gas in the outer balloon 1, connecting balloon 2 and inner balloon 5 is released through the air injection tube 5. The surgical examination instruments in the connecting tube 4 are taken out. The air in the abdominal cavity is released. At the same time, the outer balloon 1, connecting balloon 2 and inner balloon 5 contract, and the device can be removed from the body.

[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
