Technical Field
The invention relates to the technical field of medical instruments, in particular to a continuous esophageal entrance stricture dilation device.
Background
With the development of endoscopic technology and the popularization of health physical examination, the discovery of esophageal early cancer and endoscopic treatment are increasing year by year. However, esophageal stenosis caused by ESD surgery on the entrance of the esophagus and 2cm or less, and stenosis at the position (such as the stenosis position shown in figure 1) caused by eating strong acid and strong alkali by mistake are always difficult problems in the medical field. The prior art generally adopts a columnar balloon and a recyclable metal stent to perform the expansion of the narrow part, and a gastroscope is used for assisting and implanting the narrow part through an oral cavity. The existing cylindrical balloon expansion is usually effective only in a short time, and stricture appears again along with the stroke of scars; because the upper opening of the retrievable metal stent is located higher up, and in close proximity to the tracheal opening, the upper opening of the retrievable metal stent can cause tracheal compression and irritation, resulting in post-operative discomfort, coughing, and even asphyxiation. The final outcome of such patients is often gastrostomy, from which the rest of the life can no longer be taken orally, the quality of life is greatly reduced, and more seriously, many patients cannot accept the food psychologically, causing great pain.

Preferably, a fixed balloon gas injection pipeline communicated with the fixed balloon and a dilatation balloon gas injection pipeline communicated with the dilatation balloon are arranged inside the catheter; the fixed balloon gas injection cavity is arranged outside the catheter and is connected with the fixed balloon gas injection pipeline; the balloon dilatation balloon gas injection cavity is arranged outside the catheter and is connected with the balloon dilatation balloon gas injection pipeline.
Preferably, the apparatus further comprises: a handle; the wire guide cavity, the fixed balloon air injection cavity and the expansion balloon air injection cavity are respectively fixed on the handle.
Preferably, the forward end of the conduit is tapered.
Preferably, the fluid is a gas.
Compared with the prior art, the invention has the following beneficial effects:
(1) the device enters from the nasal cavity, can be fixed at the nasal cavity, realizes continuous expansion, and has better and more lasting effect compared with the existing columnar balloon.
(2) The diameter and the expansion time of the expansion saccule can be adjusted according to the requirements of the state of an illness during the treatment period, so that severe compression and stimulation of the trachea are avoided.
(3) The invention well solves the problem of esophageal entrance stenosis expansion, and greatly improves the life quality of patients.

Fig. 3 to 5 are schematic views of the device of the present invention in a use state, wherein fig. 3 is a schematic view of the device just after entering from the nasal cavity, fig. 4 is a schematic view of the fixed balloon after being inflated, and fig. 5 is a schematic view of the fixed balloon and the inflatable balloon after being inflated.
Detailed Description
The technical solution of the present invention is further described below with reference to the accompanying drawings and examples.
In the description of the present invention, the term "front end" is an end away from the operator, and "rear end" is an end close to the operator. The positional or orientational relationships indicated in the present invention are for convenience of description and simplicity of description only and thus should not be construed as limitations of the present invention.
As shown in FIG. 2, the esophageal entrance stricture sustained dilation device of the present invention comprises: the device comprises a catheter 1, a fixed balloon 2 and an expansion balloon 3 which are sequentially sleeved on the outer side of the catheter 1, a wire guide cavity 4 communicated with the catheter 1, a fixed balloon air injection cavity 5 used for inputting fluid into the fixed balloon 2, and an expansion balloon air injection cavity 6 used for inputting fluid into the expansion balloon 3; the fixing balloon 2 and the dilatation balloon 3 are in contact or close to each other.
The gas injection cavity can be connected with a connector and then connected with a two-way valve for controlling gas injection quantity and adjusting the size of the air bag. The guidewire lumen 4 is used to place a guidewire to guide the device into the surgical field. The device of the invention is entered from the nasal cavity, and the fixed saccule 2 is firstly sent to the narrow section. The fixed saccule 2 and the expansion saccule 3 are made of elastic materials. The fixed balloon 2 is used for limiting, and the device can not be pulled out after being expanded, so that the device is kept in the operation area. The dilatation balloon 3 is used to dilate the stenosis. Because the fixed balloon 2 is contacted with or close to the expansion balloon 3, after the fixed balloon 2 is inflated, the handle 7 of the device is slightly pulled until the fixed balloon cannot be pulled out, and the expansion balloon 3 is accurately positioned at the narrow part. The fixing device at the nostril can realize the continuous expansion of the narrow part.
In some embodiments, a fixed balloon inflation pipeline communicated with the fixed balloon 2 and a dilatation balloon inflation pipeline communicated with the dilatation balloon 3 are arranged inside the catheter 1; the fixed balloon gas injection cavity 5 is arranged outside the catheter 1 and is connected with a fixed balloon gas injection pipeline; the balloon inflation cavity 6 is arranged outside the catheter 1 and is connected with the balloon inflation pipeline.
The apparatus of the present invention further comprises: a handle 7; the guide wire cavity 4, the fixed balloon air injection cavity 5 and the expansion balloon air injection cavity 6 are respectively fixed on the handle 7.
The fluid injected into the fixed balloon 2 and the inflatable balloon 3 may be selected as long as the balloons are inflated, and a gas may be used. After the gas in the fixing balloon 2 and the expanding balloon 3 is released, the device can be taken out.
The front end of the catheter 1 is designed to be tapered to facilitate the operation.
The device is mainly used in esophageal dilatation operation under an endoscope, and the device is designed into different specifications according to the length and the diameter of the dilatation balloon 3. An example of a method of use is as follows:
as shown in fig. 3, the guide wire 8 is inserted through the stenosis under direct endoscopic vision, the catheter is guided through the stenosis, the length of the stenosis is assessed by angiography, a device for dilating the balloon 3 of the corresponding length is selected, the guide wire 8 is exchanged from the oral cavity to the nasal cavity, the device is inserted along the guide wire 8, and the fixation balloon 2 is sent under the stenosis under X-ray. As shown in fig. 4, the fixed balloon 2 is injected with air through the fixed balloon air injection cavity 5, and the handle 7 of the device is slightly pulled until the device can not be pulled out continuously. As shown in fig. 5, the inflatable balloon 3 is inflated to a suitable diameter by the inflatable balloon inflation chamber 6. A fixing device at the nostril. Then, the expansion maintaining time and whether the expansion diameter is further increased are determined according to the postoperative condition of the patient.
In conclusion, the device is provided with the fixing saccule, so that the device is beneficial to limiting and assisting in positioning, and the expansion saccule can be used for expanding the narrow part. The device of the invention can enter from the nasal cavity, has simple and convenient use method, and can continuously dilate the narrow part according to the requirement.
