Description

A balloon device for assisting visual field under endoscope

technical field

The utility model relates to the field of medical equipment, in particular to a balloon device for assisting vision under an endoscope.

Background technique

In recent years, with the advancement of technology, endoscopy has long been not only a simple diagnostic tool, but also a good therapeutic tool for endoscopists. Regarding the gastric wall of the digestive tract, there are mucosal layer, submucosa layer, basal layer propria and serosa layer from inside to outside; the submucosa layer contains rich blood vessels, nerves and lymphatic vessels, which is also the possibility that once a tumor grows into the submucosa layer, it may develop The main reason for the transfer is that the submucosa has another characteristic, that is, it is very loose. Injecting liquid into it with an injection needle can stretch the submucosa. ESD (endoscopic submucosal dissection) utilizes this characteristic of the submucosa. After the injection stretches the mucosal layer, under the direct vision of the endoscope, the lesions of the mucosal layer are gradually and completely peeled off. The biggest advantage of ESD lies in its minimal invasiveness, because it only partially removes the mucous membrane and has almost no effect on the state of the whole body. In the absence of complications, the patient can resume eating and drinking within 24 hours after the operation, and can be discharged from the hospital in 3 to 4 days. At the same time, The digestive tract, such as the esophagus or stomach, is preserved without affecting its function. However, the current clinical ESD surgery requires high endoscopic skills of the operator, and the operation time for mucosal stripping is long. If the mucosal stripping is not handled properly, complications such as bleeding and perforation may occur.

In order to solve the above-mentioned technical problems, the utility model provides a balloon device for assisting vision under an endoscope, which includes a balloon and a tube connected to the balloon. There is more than one coil for mounting surgical tissue clips.

In the present invention, the balloon includes a balloon inner core and a balloon body, more than one through hole is provided between the balloon inner core and the balloon body, and the tube body communicates with the balloon inner core.

In the utility model, there are four coils.

In the present invention, the included angle between the adjacent coils is 90 degrees, which ensures that the tissue clips are spread apart and the lesion is clamped in a large area.

In the utility model, the end of the tube body facing away from the balloon is provided with a connector, and the connector is sealed and connected with the tube body to prevent the balloon from leaking, and to assist access to a syringe for inflation or liquid filling.

In the utility model, the connecting head is provided with a detachable one-way valve to prevent air leakage of the balloon.

In the present invention, the expanded cross-section of the balloon is flat apple-shaped, and the shape of the balloon is similar to that of an apple, enclosing more tissues with the smallest height and facilitating the arrangement of coils.

In the utility model, after the expansion of the balloon, the local tissue is stretched, and the endoscope is used to expand the field of view, which facilitates the release of the tissue clip and facilitates the operation.

Beneficial effects: the device can quickly and effectively assist the successful completion of ESD surgery, shorten the operation time, reduce the pain of patients, reduce the labor intensity of doctors, and fully expose the ESD mucosa to the field of view of the endoscope.

Detailed ways

The utility model will be described in detail below in conjunction with accompanying drawing.

Example:

As shown in Fig. 1, this embodiment provides a balloon device for assisting vision under endoscope, including balloon inner core 1, through hole 2, balloon 3, coil 4, tube body 5, connector 6 and one-way Valve 7; four coils 4 are bound to the proximal end of the balloon inner core 1, the tube body 5 is glued and communicated with the balloon inner core 1, and the distal end of the balloon inner core 1 is sealed with glue or other processes, and the tube body 5 The proximal end is in sealing connection with the connector 6. More than one through hole 2 is provided between the balloon inner core 1 and the balloon 3 .

In this embodiment, the inner core 1 of the balloon is preferably made of plastic tubing, the balloon 3 is preferably made of rubber, and the coil 4 is preferably made of nylon thread.

There are four coils 4, and the angle between adjacent coils 4 is 90 degrees. Ensure that the tissue clips 8 are spread apart, effectively clamping the edges of the incised opening.

After the balloon is infused with liquid or gas, it becomes a flat apple state, enclosing more tissues with the smallest height.

As shown in Fig. 2, the one-way valve 7 and the connector 6 are connected at the proximal end of the tube body. During ESD surgery, the air or liquid can be fed through the one-way valve 7 as needed, and the one-way valve 7 does not need to be locked twice; if it is necessary to deflate or release the liquid in the middle, the one-way valve can be rotated 7 times, or a three-way valve can be selected And other valve bodies that can rotate to deflate (liquid). The one-way valve 7 or other three-way valves here are non-essential parts, and these parts can be removed when using a pressure pump that can maintain pressure.

The principle and method of use of this embodiment:

Principle: This device utilizes the stretchability of the balloon 3, injects appropriate gas or liquid according to the size of the cut mucosa, fixes the balloon body and injects the liquid into the balloon, the mucosal layer will wrap the balloon body, perfect The submucosa can be fully exposed, and if necessary, the tube 5 outside the body can be pulled to lift the mucosa more effectively, and sometimes the gravity of the capsule 3 can be used to adjust the patient's position to more effectively expose the submucosa.

How to use: As shown in Figure 3 and 4, the preoperative preparation for ESD of early gastric cancer, determine the location of early cancer, place the endoscope, mark it, and withdraw the endoscope after incision; use this auxiliary traction balloon with the endoscope In parallel, then take 1PC of tissue clips and clamp one of the coils of the balloon coil 4 at the distal end of the clamp channel, and send the endoscope and tissue clips of the utility model to the wound at the same time; clamp the tissue clips to the edge of the mucosal layer 10, Release after clamping, withdraw from the tissue clamping body, and clamp the other three coils 4 in Figure 3 to the edge of the wound evenly with tissue clamps in the same way;

Use a pressure pump or syringe to inject gas or liquid to inflate the balloon to an appropriate size, so that the circumference of the submucosa is exposed to the endoscopic field of view;

Lower band injection function ESD high-frequency electric knife, inject normal saline or other liquids to raise the submucosa 9, and start the corresponding submucosal dissection until early cancer

After all the stripping, the stripped tissues are taken out of the body together with the endoscope and the balloon.

The utility model provides a balloon device for assisting vision under an endoscope. There are many methods and approaches for realizing the technical solution.
