Abstract

This utility model relates to the field of medical devices, specifically to a device for fenestrating and decompressing jaw cysts. It comprises a guide section, a connecting section, and a base arranged sequentially from top to bottom. The guide section is a frustum of a cone, with its smaller diameter section located at the top. The connecting section is a cylinder, with its diameter smaller than the diameter of the bottom of the guide section. The base is an elliptical cylinder, with its minor axis larger than the diameter of the bottom of the guide section. A through-hole extending from the bottom of the base to the top of the guide section forms a drainage channel. This utility model utilizes the inherent resilience of the soft tissue within the cyst cavity to ensure that the guide section and connecting section remain fixed within the cyst cavity and do not fall off. Simultaneously, the elliptical cylindrical base effectively prevents the base from entering the cyst cavity and conforms to the shape of the vestibular sulcus, resulting in a comfortable, foreign-body feel.

Description

Jaw cyst windowing and pressure reducing device

Technical Field

The utility model relates to the field of medical appliances, in particular to a jaw cyst windowing and pressure reducing device.

Background

Jaw cyst is a common benign lesion of jaw in oral cavity, and has slow early development and usually no obvious clinical symptoms. The jaw cyst grows up gradually over time, causing tooth displacement, facial deformity, infection and even pathological fracture. Current research shows that windowing decompression is a more effective treatment method for large-sized jaw cysts (diameter more than 3.5 cm). The surgical method can effectively promote the reduction of the volume of the capsule cavity and the formation of new bones around the capsule cavity, thereby reducing the surgical injury and possible damage of important vascular nerves to the greatest extent. In recent years, efforts have been made to improve the devices of cyst fenestration drainage devices to maximize the efficacy of reduced pressure.

The patent number ZL202222130084.3 discloses a cyst plug device, which mainly comprises a cyst window drainage device and a cyst plug device, wherein the bottom of the cyst window drainage device is inflated and fixed locally. But the expansion size cannot be determined, the position of the buckle in the operation process is not determined due to the fact that the expansion part is elliptical, and moreover, the expansion part is bow-back type, the expansion part can possibly slide out along a windowing in the use process, finally, the production cost of the device is relatively high, and a certain experience skill is required in the operation.

Detailed Description

In order to describe the technical contents, the achieved objects and effects of the present utility model in detail, the following description will be made with reference to the embodiments in conjunction with the accompanying drawings.

Referring to fig. 1-2, the utility model adopts the technical proposal that the jaw cyst windowing and decompressing device comprises a guiding part 1, a connecting part 2 and a base 3 which are sequentially arranged from top to bottom;

The guide part 1 is a round table body, and the small diameter section of the guide part is positioned above the round table body;

The connecting part 2 is a cylinder, and the diameter size of the connecting part is smaller than that of the bottom of the guiding part;

The base is a 3-elliptic cylinder, and the short axis size of the base is larger than the diameter size of the bottom of the guide part;

The bottom of the base 3 is provided with a through hole 31 penetrating to the upper part of the guide part to form a drainage channel 4.

From the above description, it is known that the guide part 1 and the connecting part 2 form a stepped surface, when the guide part 1 and the connecting part 2 are both positioned in the capsule cavity, after the incision of the capsule cavity is sutured, soft tissues adhere around the connecting part 2 by utilizing the rebound characteristic of the soft tissues in the capsule cavity, so that the guide part 1 can be effectively prevented from moving to the outside, the guide part 1 and the connecting part 2 are ensured to be fixed in the capsule cavity, in addition, the short axis size of the base is larger than the size of the connecting part, therefore, the base can be effectively prevented from entering the capsule cavity, the structure of the elliptic cylinder accords with the shape of the vestibular sulcus, the condition that the pain of a patient cannot be matched for a long time because the vestibular sulcus is pressed by a circular structure is avoided, and the wearing feeling of the patient is more comfortable.

Preferably, the guide portion 1, the connecting portion 2 and the base 3 are integrally formed as an elastic block.

From the above description, the integrated processing and forming mode is adopted, so that the production cost can be saved, and the popularization in industry is facilitated.
