Description

Technical Field

[0001] The utility model relates to the technical field of laparoscopic surgery, in particular to an abdominal cavity expansion device for laparoscopic surgery. Background Art

[0002] Laparoscopically assisted extraperitoneal surgery, such as adrenal tumor resection, nephrectomy, radical prostatectomy, etc., requires first expanding a space outside the peritoneum, injecting carbon dioxide to form a surgical operating space, and then inserting a peritoneal puncture cannula through the abdominal wall. The laparoscope and surgical instruments are inserted along the puncture cannula for operation. Therefore, the quality of the expansion of the extraperitoneal space directly affects the quality of the operation.

[0003] Most of the existing methods for expanding the extraperitoneal space in clinical practice use medical latex gloves tied together with a silicone tube to form a homemade expansion air bag. When in use, the expander is inserted into the extraperitoneal space through the laparoscopic puncture cannula, and air is repeatedly injected from the silicone tube with a 50 ml medical syringe to expand the medical gloves to a certain volume, thereby expanding the surgical space outside the peritoneum; however, this expander uses an ordinary medical syringe to inject air, and it is necessary to repeat the steps of injecting air, clamping the tube, pumping air, and injecting air, which is a cumbersome process.

[0004] In view of the above problems, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0026] like Figure 1-4 As shown, an abdominal cavity expansion device for laparoscopic surgery includes a trachea 1, a three-way tube 2, a balloon 3, an airbag bag 4 and a clamp fixing structure. The trachea 1 is connected to one tube opening of the three-way tube 2, and the balloon 3 is connected to the other tube opening of the three-way tube 2. The trachea 1 and the balloon 3 are arranged in a straight line, and a valve 21 is provided on the third tube opening of the three-way tube 2.

[0027] The airbag bag 4 is installed at one end of the trachea 1 away from the three-way pipe 2, and the clamp fixing structure is installed at the connection position between the airbag bag 4 and the trachea 1. The interiors of the balloon 3, the three-way pipe 2, the trachea 1 and the airbag bag 4 are connected, and the gas in the balloon 3 can enter the airbag bag 4 through the three-way pipe 2 and the trachea 1 to expand the airbag bag 4;

[0028] When the valve 21 is in an open state, external air can enter the balloon 3 through the third pipe opening. When the balloon 3 is squeezed, the air in the balloon 3 can enter the airbag belt 4 through the three-way pipe 2 and the trachea 1.

[0029] The clamping ring fixing structure comprises a first half clamping ring 5, a second half clamping ring 6 and a fastening bolt 7. The first half clamping ring 5 and the second half clamping ring 6 are both semicircular rings. One end of the first half clamping ring 5 is rotatably connected with one end of the second half clamping ring 6 through a rotating shaft. The first half clamping ring 5 and the second half clamping ring 6 are rotated, separated from each other or tightly held with each other. The other end of the first half clamping ring 5 is detachably connected with the other end of the second half clamping ring 6 through the fastening bolt 7.

[0030] The inner concave surface of the first half of the snap ring 5 is provided with a first rubber pad 51, and the inner concave surface of the second half of the snap ring 6 is provided with a second rubber pad 61. The first rubber pad 51 and the second rubber pad 61 are jointly attached to the connection position of the airbag bag 4 and the trachea 1. The first rubber pad 51 and the second rubber pad 61 can squeeze the connection position of the airbag bag 4 and the trachea 1, so that the connection position of the airbag bag 4 and the trachea 1 is more secure.

[0031] The first rubber pad 51 and the second rubber pad 61 are both semicircular. The first rubber pad 51 is concentric with the first half of the snap ring 5 , and the second rubber pad 61 is concentric with the second half of the snap ring 6 .

[0032] The first half retaining ring 5 is provided with a first through hole 52 at the end away from the rotating shaft, and the second plate retaining ring 6 is provided with a second through hole 62 at the end away from the rotating shaft. The first through hole 52 and the second through hole 62 are aligned with each other, and the first half retaining ring 5 and the second half retaining ring 6 are detachably connected by fastening bolts 7 passing through the first through hole 52 and the second through hole 62.

[0033] When the first half of the snap ring 5 and the second half of the snap ring 6 are attached to each other, the centers of the first half of the snap ring 5 and the second half of the snap ring 6 coincide with each other, and the centers of the first rubber pad 51 and the second rubber pad 61 coincide with each other.

[0034] The first rubber pad 51 and the second rubber pad 61 have the same thickness. When the first rubber pad 51 and the second rubber pad 61 are enclosed, the diameter of the space between the first rubber pad 51 and the second rubber pad 61 is smaller than the diameter of the connection position between the trachea 1 and the airbag bag 4. That is, as the fastening bolts 7 are gradually tightened, the first rubber pad 51 and the second rubber pad 61 generate a gradually increasing squeezing force on the connection position between the trachea 1 and the airbag bag 4.

[0035] The surface of the balloon 3 is provided with a plurality of anti-slip grooves 31, so that the balloon 3 can be easily operated when held.

[0036] The trachea 1 and the balloon 3 are both connected to the three-way pipe 2 by plugging or threading.

[0037] In summary: when in use, the airbag bag 4 is placed in the surgical incision position of the peritoneum, and the nurse holds the balloon 3 and squeezes it continuously, and the air in the balloon 3 enters the airbag bag 4 through the trachea 1, gradually expanding the airbag bag 4, and the airbag bag 4 expands the surgical incision position of the peritoneum, making it easier to insert the abdominal puncture cannula;

[0038] By tightening the fastening bolts 7, the first rubber pad 51 and the second rubber pad 61 clamp the connection position of the trachea 1 and the airbag bag 4 and have a large squeezing force, so that the trachea 1 and the airbag bag 4 are firmly connected, and the airbag bag 4 will not leak or fall off during the inflation process.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
