Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically to a device for opening and decompressing jaw cysts. Background Technology

[0002] Jawbone cysts are common benign lesions of the jawbone in the oral cavity. They develop slowly in the early stages and are usually asymptomatic. Over time, the cysts gradually grow larger, potentially causing tooth displacement, facial deformities, infection, and even pathological fractures. Current research indicates that fenestration decompression surgery is a relatively effective treatment for large jawbone cysts (diameter greater than 3.5 cm). This procedure effectively reduces the size of the cyst cavity and promotes new bone formation around the cyst, thereby minimizing surgical trauma and potential damage to important blood vessels and nerves. In recent years, researchers have focused on improving the device of the cyst fenestration drainage system to achieve maximum decompression efficacy.

[0003] Chinese Patent No. ZL202222130084.3 discloses a jawbone cyst plugging device, which is a cyst fenestration drainage device that mainly expands and fixes the bottom of the cyst by local inflation. However, the size of the expansion is uncertain, the expanded part is elliptical and the position of the latch is unclear during operation, and its arched shape may cause it to slide out along the opening during use. Finally, the production cost of this device is relatively high, and its operation during surgery requires certain experience and skills. Utility Model Content

[0004] The purpose of this invention is to provide a device for opening windows and decompressing jaw cysts.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a jawbone cyst fenestration decompression device, comprising a guide part, a connecting part, and a base arranged sequentially from top to bottom;

[0006] The guide part is a frustum, with its minor diameter section located at the top;

[0007] The connecting part is a cylinder, and the diameter of the connecting part is smaller than the diameter of the bottom of the guide part;

[0008] The base is larger than the diameter of the bottom of the guide section;

[0009] The bottom of the base has a through hole extending to the top of the guide section, forming a drainage channel.

[0010] Furthermore, the outer side of the guide portion is uniformly provided with opening grooves; the opening grooves penetrate into the drainage channel and extend from the top of the guide portion to the bottom of the guide portion.

[0011] Furthermore, the guide portion, connecting portion, and base are integrally formed as an elastic block.

[0012] Furthermore, the guide portion, connecting portion, and base are all made of medical-grade silicone blocks.

[0013] Furthermore, the base is an elliptical cylinder, and the minor axis of the base is larger than the diameter of the bottom of the guide portion.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The guide section has a frustum-shaped cylindrical structure, which allows for better passage through the incision in the capsule cavity, simplifying the implantation process for doctors. When both the guide section and the connecting section are located within the capsule cavity, the soft tissue within the capsule cavity adheres to the connecting section due to the elasticity of the soft tissue itself, thanks to the suturing of the capsule cavity incision. Since the diameter of the connecting section is smaller than the diameter of the bottom of the guide section, when the guide section moves outward from the capsule cavity, the soft tissue acts on the connecting section, providing a reaction force to prevent the guide section from shifting, ensuring that the guide section and the connecting section are fixed within the capsule cavity.

[0016] 2. The base is located outside the sac cavity, and its short axis is larger than the connecting part, which can effectively prevent the base from entering the sac cavity; and the structure of the elliptical cylinder conforms to the shape of the vestibular sulcus, avoiding the pain caused by the circular structure compressing the vestibular sulcus, which would prevent the patient from being unable to cooperate for a long time.

[0017] 3. This utility model is small in size and conforms to the anatomical structure of the oral cavity. There is no obvious foreign body sensation when wearing it. Patients can directly rinse it at any time through the drainage channel, avoiding repeated visits, while ensuring the cleanliness of the cyst cavity and reducing the possibility of inflammation.

[0023] 1. Guide section; 11. Opening groove; 2. Connecting section; 3. Base; 31. Through hole; 4. Drainage channel. Detailed Implementation

[0024] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0025] Please refer to Figures 1-2 As shown, the technical solution adopted by this utility model is: a jawbone cyst fenestration decompression device, which includes a guide part 1, a connecting part 2 and a base 3 arranged sequentially from top to bottom;

[0026] The guide part 1 is a frustum, with its minor diameter section located at the top;

[0027] The connecting part 2 is a cylinder, and the diameter of the connecting part is smaller than the diameter of the bottom of the guide part;

[0028] The base is a 3-elliptical cylinder, and the minor axis of the base is larger than the diameter of the bottom of the guide section;

[0029] The bottom of the base 3 is provided with a through hole 31 extending to the top of the guide section, forming a drainage channel 4.

[0030] As described above, a stepped surface is formed between the guide part 1 and the connecting part 2. When both the guide part 1 and the connecting part 2 are located within the cyst cavity, after the cyst cavity incision is sutured, the soft tissue within the cyst cavity adheres to the area around the connecting part 2 due to its own elasticity, effectively preventing the guide part 1 from moving outward. This ensures that the guide part 1 and the connecting part 2 are fixed within the cyst cavity. Furthermore, the short axis dimension of the base is larger than the dimension of the connecting part, thus effectively preventing the base from entering the cyst cavity. Moreover, the structure of the elliptical cylinder conforms to the shape of the vestibular sulcus, avoiding the pain caused by the circular structure compressing the vestibular sulcus, which prevents patients from wearing it for extended periods, resulting in greater comfort for the patient.

[0031] Preferably, the guide part 1, the connecting part 2, and the base 3 are integrally formed as an elastic block.

[0032] As can be seen from the above description, adopting an integrated processing and molding method can save production costs and is conducive to its promotion in the industry.

[0033] Preferably, the guide part 1, the connecting part 2, and the base 3 are all medical silicone blocks.

[0034] As can be seen from the above description, medical-grade silicone is used, which has excellent softness and can simulate the softness of human tissue, so it will not cause discomfort to the user during use; in addition, it will not cause immune response, cytotoxicity or irritation. Example 1

[0035] Please refer to Figures 1-2 As shown, the technical solution adopted in this embodiment is: a jawbone cyst fenestration decompression device, which includes a guide part 1, a connecting part 2 and a base 3 arranged sequentially from top to bottom;

[0036] The guide part 1 is a frustum, with its minor diameter section located at the top;

[0037] The connecting part 2 is a cylinder, and the diameter of the connecting part is smaller than the diameter of the bottom of the guide part;

[0038] The base is a 3-elliptical cylinder, and the minor axis of the base is larger than the diameter of the bottom of the guide section;

[0039] The bottom of the base 3 is provided with a through hole 31 extending to the top of the guide section, forming a drainage channel 4;

[0040] The guide part 1, the connecting part 2, and the base 3 are integrally formed medical silicone blocks. Example 2

[0041] Please refer to Figures 3-4 As shown, the difference between Example 2 and Example 1 is that:

[0042] The outer surface of the guide part 1 is uniformly provided with opening grooves 11; the opening grooves 11 penetrate into the drainage channel 4 and extend from the top of the guide part 1 to the bottom of the guide part 1.

[0043] As can be seen from the above description, by using the above settings and the opening groove 11, the front end of the guide part 1 can be pinched into a smaller shape, making it easier for the guide part 1 to be aligned with the cyst cavity incision, and making it convenient for the doctor to quickly implant the guide part 1 into the cyst cavity.

[0044] The working principle of this utility model is as follows: For patients with cystic lesions of the jawbone, local anesthetic is injected at the weak point of the cyst cavity. After the anesthesia takes effect (5 minutes), a cyst cavity tissue with a diameter of about 5mm is removed. The guide part 1 and the connecting part 2 are pressed in along the pathological incision of the cyst. The process can be stopped after the guide part 1 and the connecting part 2 have entered the cyst cavity.

[0045] When the soft tissue inside the cyst cavity is compressed, it fits the guide part 1 and the connecting part 2 due to its elasticity. Since the size of the connecting part 2 is smaller than the bottom size of the guide part 1, the guide part 1 and the connecting part 2 can be fixed inside the cyst cavity.

[0046] Appropriate suturing of the incision ensures that the width of the incision is smaller than the size of the short axis of the base, preventing the base from entering the cyst cavity. At the same time, the small incision also prevents soft tissue from overflowing out of the cyst cavity, allowing for better fixation of the guide portion 1 and the connecting portion 2 within the cyst cavity.

[0047] Insert the flushing catheter along the drainage channel to flush the fluid in the sac cavity. Once the procedure is complete, instruct the patient to flush regularly.

[0048] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
