Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a double-balloon structure for endoscopic-assisted insertion. Background Technology

[0002] Endoscopic submucosal dissection (ESD) is a minimally invasive, or even ultra-minimally invasive, endoscopic treatment technique primarily used to remove superficial tumors and precancerous lesions of the digestive tract. Compared to traditional surgery, ESD is less invasive, has a faster recovery time, and is less expensive, making it one of the preferred treatment methods for early-stage digestive tract tumors.

[0003] In ESD procedures, endoscopic tissue forceps are frequently used to assist the procedure; this product must be used in conjunction with a medical endoscope. However, in routine operations, we have encountered some problems. For example, inside the intestines, the rotation of the medical endoscope alters the position of the tissue forceps, thereby changing the operating position of the surgical instruments. This alteration is not the desired effect for the surgeon, leading to inconvenience in the procedure and prolonging the operation time. Utility Model Content

[0004] To address this issue, we propose a dual-balloon structure for endoscopic-assisted insertion. This structure employs an innovative "outer balloon + inner balloon" design. By controlling the inflation status of the outer and inner balloons, it effectively solves the problem of tissue forceps position changes caused by endoscope rotation, which in turn affects the operation position of surgical instruments. This balloon structure is simple and easy to operate, significantly reducing the complexity of surgical procedures.

[0005] This utility model is achieved through the following technical solutions: A double-balloon structure for endoscopic-assisted advancement, comprising: An endoscope connector, with a central channel configured as an endoscope cavity, includes a first insertion groove on the outer surface of the endoscope connector and a second insertion groove on the surface of the endoscope cavity. The external balloon is fitted onto the outer surface of the endoscope connector; An inner balloon is fitted onto the inner surface of the endoscope cavity; The first inflation conduit has one end fixed in the first insertion groove for inflating or deflating the external balloon, and the other end connected to the inflation / deflation device. The second inflation conduit has one end fixed in the second insertion groove for inflating or deflating the inner balloon, and the other end connected to the inflation / deflation device.

[0006] Preferably, the endoscope connector is provided with a three-lumen tube located around the endoscope cavity, and a three-lumen tube is fixed inside the three-lumen tube.

[0007] Preferably, the endoscope connector has a first wire rope through hole and a second wire rope through hole respectively located on both sides of the periphery of the endoscope cavity, for actuating the wire rope to pass through and limiting its movement.

[0008] Preferably, the cross-section of the first insertion slot is set to be arc-shaped, which can fully accommodate the first inflation conduit.

[0009] Preferably, the cross-section of the second insertion slot is set to be arc-shaped, which can fully accommodate the placement of the second inflation conduit.

[0010] Preferably, the three-cavity tube is provided with a clamping channel cavity, a first wire rope cavity, and a second wire rope cavity. The clamping channel cavity is used for clamping through, and the first wire rope cavity and the second wire rope cavity are both used for actuating the wire rope through.

[0011] Preferably, both the first and second wire rope through holes are designed with oblique holes, and their axes are in the shape of an "eight". The narrow end of the "eight" shape faces the three-lumen tube, and the wide end of the "eight" shape is located on the left end face of the endoscope connector.

[0012] Preferably, the outer diameter of the external balloon can reach 60 mm when it is inflated.

[0013] Compared with existing technologies, the double balloon design of this utility model allows the outer balloon to expand the intestine, increasing the surgical field and instrument operation space, while the inner balloon can fix the endoscope in the endoscope connector, preventing the endoscope from loosening or rotating, making the surgical operation simpler and more efficient.

[0025] refer to Figures 1-3 This embodiment provides a double-balloon structure for endoscopic-assisted insertion, comprising an endoscope connector 1, an outer balloon 2, an inner balloon 3, a first inflation conduit 4, and a second inflation conduit 5. The outer balloon 2 is fitted onto the outer surface of the endoscope connector 1, and the two are fixed by adhesive. The inner balloon 3 is fitted onto the inner surface of the endoscope cavity 16, and the two are fixed by adhesive. Both the outer balloon 2 and the inner balloon 3 can be inflated, and the outer diameter of the outer balloon 2 can reach 60 mm when inflated.

[0026] like Figures 4-6As shown, in this embodiment, the endoscope connector 1 has a central channel configured as an endoscope cavity 16 with a cavity diameter not exceeding 14 mm, which is sleeved on the end of the endoscope. The endoscope connector 1 includes a first insertion groove 11 disposed on the outer surface of the endoscope connector 1 and a second insertion groove 12 disposed on the surface of the endoscope cavity 16. A three-lumen tube 13 is also disposed on the endoscope connector 1 around the endoscope cavity 16, and a three-lumen tube 6 is fixed inside the three-lumen tube 13. The two are fixedly connected by adhesive. Inside the endoscope connector 1, a first wire rope through hole 14 and a second wire rope through hole 15 are respectively disposed on both sides of the outer periphery of the endoscope cavity 16, for actuating the wire rope to pass through and limiting its movement.

[0027] In this embodiment, the first inflation conduit 4 has one end fixed in the first insertion groove 11 for inflating or deflating the outer balloon 2, and the other end is connected to the inflation / deflating device; the second inflation conduit 5 has one end fixed in the second insertion groove 12 for inflating or deflating the inner balloon 3, and the other end is connected to the inflation / deflating device.

[0028] Furthermore, in this embodiment, the cross-section of the first insertion slot 11 is set to an arc shape, which can completely accommodate the first inflation tube 4, and the two are fixedly connected by adhesive. The cross-section of the second insertion slot 12 is set to an arc shape, which can completely accommodate the second inflation tube 5, and the two are fixedly connected by adhesive.

[0029] In this embodiment, both the first wire rope through hole 14 and the second wire rope through hole 15 adopt an oblique hole design, and their axes are in the shape of an "eight". The narrow end outlet of the "eight" shape faces the three-lumen tube 13, and the wide end outlet of the "eight" shape is located on the left end face of the endoscope connector 1.

[0030] like Figure 7 As shown, the three-cavity tube 6 in this embodiment is provided with a clamping channel cavity 61, a first wire rope cavity 62, and a second wire rope cavity 63. The clamping channel cavity 61 is used for clamping through, and the first wire rope cavity 62 and the second wire rope cavity 63 are used for actuating the wire rope through.

[0031] In this embodiment, the end of the medical endoscope is first inserted into the endoscope cavity 16 of the endoscope connector 1, ensuring that the end face of the end of the endoscope is flush with the outlet end face of the first wire rope through hole 62 and the second wire rope through hole 63 located on the left end face of the endoscope connector 1. Then, the inner balloon 3 is inflated through the second inflation tube 5 to stably fix the medical endoscope in the endoscope connector 1 and prevent it from loosening. The medical endoscope and the double balloon structure are then delivered to the designated intestinal position through the oral cavity or anus. Next, the outer balloon 2 is inflated through the first inflation tube 4 to expand the intestine, increase the surgical field of view and instrument operation space, and facilitate instrument advancement. Then, the gas in the inner balloon 3 is discharged through the second inflation tube 5. At this time, the medical endoscope is released from the fixation of the endoscope connector 1 and can rotate freely without changing the position of the outer balloon 2 during rotation, thus solving the rotation problem of the medical endoscope, avoiding changes in the position of the outer balloon 2, and ensuring that the surgical operation is not affected.
