Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a temperature and pressure controlled irrigation device for postoperative fenestration of jawbone cysts. Background Technology

[0002] Jawbone cysts are fluid-filled cystic masses that appear within the jawbone. They gradually erode the surrounding bone, affecting the normal structure and function of the jawbone. Jawbone cysts are mainly divided into two categories: odontogenic cysts and non-odontogenic cysts. Odontogenic cysts are mostly caused by residual epithelial tissue or inflammatory stimulation during tooth development. For example, periapical cysts are often caused by long-term stimulation from periapical inflammation, leading to epithelial proliferation and cyst formation. Their cyst walls are usually thin and contain pale yellow fluid. Non-odontogenic cysts originate from residual epithelial tissue or other non-odontogenic factors during embryonic development. For example, nasopalatine duct cysts occur in the nasopalatine duct region, but their pathogenesis is not fully understood.

[0003] Currently, the treatment of jaw cysts mainly relies on surgery. Traditional surgical methods include cyst curettage and fenestration. Cyst curettage is suitable for cysts that are small in size, have clear boundaries, and are not tightly adhered to surrounding important structures. This procedure completely removes the cyst wall through surgery. Its advantage is that it can remove the lesion in one go and reduce the risk of recurrence. However, this procedure is more invasive and may damage surrounding nerves, blood vessels, and normal dental tissues, leading to postoperative complications such as local numbness, loose teeth, or even tooth loss.

[0004] Fenestration is suitable for cysts that are large, extensive, or located near important anatomical structures. Direct curettage can cause severe functional impairment. Fenestration involves creating a window on the cyst surface to drain the cystic fluid, reduce cystic pressure, and promote surrounding bone regeneration. Its advantages include minimal trauma, maximizing the preservation of the normal structure and function of the jawbone, and minimizing damage to surrounding tissues. However, long-term follow-up and care are required after fenestration to ensure successful cyst healing. Post-fenestration, patients need to wear a septum tampon and perform self-irrigation of the cyst cavity to keep it clean, prevent infection, and promote healing. However, self-irrigation of the cyst cavity presents several difficulties: First, the temperature of the irrigation fluid is difficult to control; excessively cold or hot fluid can irritate the surgical area and affect healing. Second, the irrigation pressure is difficult to control; too low a pressure will not effectively remove residues, while too high a pressure may cause bleeding or pain. In addition, improper operation may lead to incomplete irrigation or increase the risk of infection. Therefore, developing a jawbone cyst irrigator capable of constant temperature and pressure irrigation is of great significance for improving treatment outcomes, reducing patient suffering, and promoting postoperative recovery.

[0005] As disclosed in CN117323488A, a visual detection mandibular cyst irrigator belongs to the field of medical device technology. It includes a display, handle, hose, irrigation component, and moving component. The irrigation component can be easily inserted into the patient's mouth. The irrigation component has a hollow spherical structure with multiple irrigation holes. The irrigation fluid can be sprayed in multiple directions through the irrigation holes to achieve 360° irrigation of the cyst cavity, thereby eliminating irrigation blind spots and improving the cleaning effect of the cyst cavity to promote the rapid recovery of the jawbone. A camera is installed on the irrigation component, which can clearly observe the internal situation and accurately clean the cyst cavity. It is simple to operate and has a good cleaning effect. The moving component can adaptively adjust the irrigation angle and control the irrigation component to move to the corresponding position according to the camera image, so that irrigation can be performed. The visual method ensures that viscous secretions are completely rinsed away.

[0006] Regarding the above solutions: Although the reference document states that the irrigation fluid can be sprayed in multiple directions through the irrigation port to achieve 360° irrigation of the cyst cavity, thereby eliminating irrigation blind spots and improving the cleaning effect of the cyst cavity, the irrigation device usually provides a water source with a fixed temperature and cannot adjust the water temperature in real time according to the specific needs of the patient. Postoperative patients are highly sensitive to water temperature, and the required water temperature range varies at different stages of recovery. A fixed water temperature may cause discomfort to the patient. At the same time, the irrigation device cannot flexibly control the water flow speed. If the water flow speed is too fast, it will lead to excessive water pressure, which can easily damage the patient's wound or cyst wall, thereby affecting recovery. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. To better understand the technical content of the present utility model, specific embodiments are provided and illustrated below. Various aspects of the present utility model are described in this disclosure with reference to the accompanying drawings, which show many illustrative embodiments. It should be understood that the various concepts and embodiments described above, as well as those described in more detail below, can be implemented in any of many ways using a temperature and pressure controlled irrigation device after jaw cyst fenestration surgery. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0027] As attached Figure 1 To be continued Figure 6 As shown: This embodiment provides a temperature and pressure controlled irrigation device for postoperative fenestration of jaw cysts, including a first housing 1, a second housing 2 and an irrigation head 8. The inner cavity of the second housing 2 is provided with a first water storage pipe 3 and a second water storage block 5. The first water storage pipe 3 is located on top of the second water storage block 5. A heating block 4 is fixedly connected to the top of the inner cavity of the first water storage pipe 3. A first water inlet pipe 6 is connected to one side of the inner cavity of the first water storage pipe 3 and the second water storage block 5. One end of the first water inlet pipe 6 extends to the outside of the second housing 2. A threaded block 7 is fixedly connected to the right side of the first housing 1.

[0028] The interior of the first housing 1 has a first cavity 9, a second cavity 10, and a third cavity 11 arranged sequentially from right to left. A water valve 12 is rotatably connected to the inner cavity of the first cavity 9. Two second water inlet pipes 13 are connected to one side of the inner cavity of the second cavity 10. One end of each of the two second water inlet pipes 13 passes through the inner cavity of the second housing 2 and is connected to the first water storage pipe 3 and the second water storage block 5, respectively. A baffle 14 is slidably connected to the inner cavity of the second water inlet pipe 13. A through groove 15 is opened on one side of the baffle 14. One side of the baffle 14 passes through the outer side of the first housing 1 and is fixedly connected to a pressing block 23. Two grooves 16 are opened on one side of the inner cavity of the third cavity 11. A limit mechanism 17 is provided in the inner cavity of the grooves 16.

[0029] Specifically, the limiting mechanism 17 includes a first short rod 171 fixedly connected to the inner cavity of the groove 16, a movable plate 172 slidably connected to the surface of the first short rod 171, one side of the movable plate 172 being fixedly connected to the baffle 14, and a spring 173 sleeved on the surface of the first short rod 171, with both ends of the spring 173 being fixedly connected to the first housing 1 and the movable plate 172 respectively.

[0030] In this embodiment, the limiting mechanism 17 moves the baffle 14, thereby sealing the second water inlet pipe 13 and preventing water from flowing out of the second water inlet pipe 13.

[0031] Specifically, a second short rod 18 is fixedly connected to the top of the water valve 12, and the top end of the second short rod 18 extends through to the outside of the first housing 1 and is fixedly connected to a handle 19.

[0032] In this embodiment, the use of the second short rod 18 and the handle 19 together increases the contact area between the user's palm and the handle 19, thereby facilitating the rotation of the water valve 12.

[0033] Specifically, the top of the handle 19 is threaded with a bolt 20, and one end of the bolt 20 is fixedly connected to an anti-slip block 21.

[0034] In this embodiment: by using the bolt 20 and the anti-slip block 21 together, as the bolt 20 moves down, the bottom of the anti-slip block 21 can be made to make close contact with the first housing 1, thereby preventing the handle 19 from rotating.

[0035] Specifically, the inner cavity of the flushing head 8 is provided with a filter block 22, and one side of the filter block 22 is in contact with the threaded block 7.

[0036] In this embodiment, the filter block 22 effectively filters out bacteria and other impurities in the water source, ensuring hygiene and safety during the rinsing process, helping to prevent cross-infection and protect the health of patients.

[0037] Specifically, a sleeve block 24 is fitted on the surface of the second housing 2, and the surface of the sleeve block 24 is provided with anti-slip texture.

[0038] In this embodiment, the use of the sleeve block 24 and the anti-slip texture increases the friction between the user's palm and the sleeve block 24, making it less likely for the user to drop the flushing device when picking it up.

[0039] Specifically, the movable plate 172 and the spring 173 form a telescopic structure, and the maximum moving distance of the movable plate 172 is equal to the deformation of the spring 173.

[0040] In this embodiment, the spring 173 ensures that the movable plate 172 is always located at the outermost edge of the inner cavity of the groove 16, making the baffle 14 less prone to displacement and improving the stability of the baffle 14 during placement.

[0041] The working principle and usage process of this utility model are as follows: In order to facilitate the flow of water, the user first rotates the bolt 20, and the anti-slip block 21 moves upward, which releases the fixation of the handle 19. Then, the user rotates the handle 19, which drives the second short rod 18 to rotate. The second short rod 18 drives the water valve 12 to rotate, keeping the through hole on the surface of the water valve 12 horizontal with the outlet of the second cavity 10 and the first housing 1, so as to facilitate the subsequent flow of water.

[0042] To facilitate wound cleaning, water enters the first water inlet pipe 6 and is stored in the inner cavity of the first water storage pipe 3 and the second water storage block 5. When the water supply in the inner cavity of the first water storage pipe 3 and the second water storage block 5 is sufficient, the user presses the lower pressing block 23. The pressing block 23 moves the baffle 14 into the third cavity 11. The baffle 14 causes the movable plate 172 to slide on the surface of the first short rod 171. When the movable plate 172 slides, it causes the spring 173 to compress. At the same time, the baffle 14 slides in the inner cavity of the second water inlet pipe 13. When the baffle 14 moves the through groove 15 to the designated position, the water can flow into the inner cavity of the second cavity 10. Then the water gradually flows out of the outside of the threaded block 7 through the inside of the water valve 12 and then enters the inner cavity of the flushing head 8.

[0043] When water enters the inner cavity of the rinsing head 8, it is first filtered through the inner cavity of the filter block 22 to prevent the spread of bacteria. Finally, the water flows out through the rinsing head 8, making it convenient to rinse the patient's wound.

[0044] In order to control the pressure of the water source during rinsing, the user turns the handle 19, which drives the second short rod 18 to rotate. The second short rod 18 drives the water valve 12 to rotate. As the water valve 12 rotates continuously, the gap between the through hole on the surface of the water valve 12 and the second cavity 10 and the water outlet of the first housing 1 gradually decreases or increases, making it easier for the user to adjust the pressure of the water source when it flows out.

[0045] To control the temperature of the water flow when it flows out, the heating block 4 is used to heat the water in the inner cavity of the first water storage pipe 3, thereby increasing the temperature of the water source. Pressing the upper pressing block 23 causes the baffle 14 to move into the interior of the third cavity 11. The baffle 14 causes the movable plate 172 to slide on the surface of the first short rod 171. When the movable plate 172 slides, it causes the spring 173 to compress. At the same time, the baffle 14 slides in the inner cavity of the second water inlet pipe 13. When the baffle 14 moves the through groove 15 to the designated position, hot water can flow into the inner cavity of the second cavity 10 and mix with cold water. When the water temperature is high, cold water can be added to the inner cavity of the second cavity 10. Conversely, if the water temperature is too low, hot water can be added to the inner cavity of the second cavity 10.

[0046] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0047] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
