Description

Technical Field

[0001] The utility model relates to the technical field of drainage devices, and in particular to an endoscopic drainage device used in a cerebral ventricle. Background Art

[0002] Acute cerebrovascular disease is one of the three major diseases that endanger human health; among them, cerebral hemorrhage accounts for 30%-40%, and cerebral hemorrhage breaks into the ventricle (including simple intraventricular hematoma) accounts for 3%-5%. A considerable part of intraventricular hematoma cannot be quickly removed due to the lack of suitable surgical instruments. With current technology, in grassroots hospitals, even in municipal tertiary hospitals, traditional silicone ventricular drainage tubes or hard channel hematoma crushing needles are still used to treat intraventricular hematoma through the old method of puncturing the lateral ventricle for drainage. These methods are time-consuming, the drainage effect of hematoma is not good, and infection and complications of hydrocephalus often lead to patient death; in large provincial and municipal tertiary hospitals, there are professional ventriculoscopes (including hard and soft mirrors) equipment and teams for the treatment of intraventricular hematoma, but this kind of professional ventriculoscope equipment is expensive, has high technical requirements, and must be completed in cooperation with professional operating rooms and anesthesia teams, and the popularity rate is not high.

[0003] Since the existing drains have no visual function, doctors generally judge whether the predetermined ventricular position has been reached based on experience, and dare not aspirate the intraventricular hematoma. Rash aspiration can easily lead to new bleeding and ventricular wall damage, and result in poor drainage of the intraventricular hematoma (most of such patients can only drain half of the hematoma), and the drainage tube is left in place for a long time (generally 3-7 days or even longer), leading to complications such as intracranial infection and hydrocephalus (infection, blood clot blockage and bloody cerebrospinal fluid stimulation can all lead to hydrocephalus), which often lead to patient death and extremely high medical expenses. Therefore, an endoscopic drain for the ventricle is provided to solve the problem that the existing ventricular drain has no visual function. Utility Model Content

[0004] One of the purposes of the utility model is to provide an endoscopic drainage device applied to a cerebral ventricle, so as to solve the problem that the existing cerebral ventricle drainage device has no visual function.

[0010] In one implementation, the roller assembly includes a mounting frame and a roller body, the mounting frame is fixedly arranged in the main cavity; the roller body is movably arranged on the mounting frame and penetrates through the main cavity, and is in transmission connection with at least one control rope.

[0011] In one implementation, the camera assembly and the lighting assembly are respectively fixedly arranged in the camera pipeline and the optical fiber pipeline; the drainage tube, the camera assembly and the lighting assembly are all disposable consumables.

[0012] In one implementation, the camera assembly and the lighting assembly are respectively detachably arranged in the camera pipeline and the optical fiber pipeline; the drainage tube is a disposable consumable.

[0013] In one implementation, a end cover is arranged on the end of the flexible tube opposite to the hard tube, and the end cover is made of a transparent material.

[0036] It should be noted that the specific working process of an endoscope drainage device for ventricles according to the present invention is as follows: Before hematoma removal surgery, open the package of the drainage tube 12, fix the rigid tube 121 in the handheld part 11, and connect the control rope connecting the flexible tube 122 to the roller assembly 114; then open the package of the extension flexible tube and connect the extension flexible tube to the drainage conduit 1231 in a communicating manner; then respectively arrange the camera assembly, the lighting assembly, and the puncture needle into the drainage tube 12 through the camera conduit 1232, the optical fiber conduit 1233, and the puncture needle conduit 1234, and then respectively connect the camera assembly, the lighting assembly, and the extension flexible tube to a display device, a light source, and a negative pressure drainage bucket to achieve rapid installation of the endoscope drainage device.

[0037] Next, the display device and the light source are powered on, the negative pressure drainage bucket is opened to apply negative pressure, the ventilation hole of the extension flexible tube is controlled for negative pressure testing, and the roller body 1142 is rolled to drive the flexible tube 122 to bend and move through the control rope for testing; after the testing is completed, the flexible tube 122 is reset to keep the flexible tube 122 in a straight state. Then, the surface layer and the joints of the drainage tube 12 and the handheld part 11 are disinfected to ensure a clean environment in the operating room to avoid the risk of infection, and doctors and nurses wear appropriate surgical gowns and gloves to maintain the hygiene of the surgical area.

[0038] The doctor holds the handheld part 11 and inserts it into the cerebral ventricle through the puncture hole. The images collected by the imaging component are displayed on the display device to observe whether the cerebral ventricle has been reached and the conditions of hematoma and effusion in the cerebral ventricle. It should be noted that the tissues and structures in the cerebral ventricle are relatively small. The camera is installed at the insertion end of the flexible tube 122, which can capture the image information inside the cerebral ventricle in real time. The lighting component provides illumination for the camera to assist in obtaining bright images. At the same time, the insertion process needs to be carefully operated to avoid damaging the surrounding tissues and blood vessels. Roll the roller body 1142 to drive the flexible tube 122 with adjustable curvature to bend in the desired direction through the control rope. Then, according to the image information on the display device, judge the location of the hematoma, and drive the curvature of the flexible tube 122 with adjustable curvature so that the port of the drainage tube 1231 reaches the effusion position and avoids large hematoma plaques. After reaching the predetermined position, control the ventilation hole on the extension flexible tube to control the negative pressure suction and collection of the bloody fluid in the cerebral ventricle. Before the drainage tube 12 is removed, roll the roller body 1142 to control the flexible tube 122 with adjustable curvature to reset, that is, to keep a straight state. After the drainage tube 12 is removed, the doctor needs to perform necessary treatments to protect the surgical area.

[0039] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0040] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
