Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an integrated minimally invasive diagnostic and treatment device for biopsy and fenestration drainage of jawbone cysts. Background Technology

[0002] Jawbone cysts are pathological cystic cavities that occur within the jawbone. They have a relatively high incidence rate, and treatment aims to completely remove the lesion, reduce the risk of recurrence, minimize trauma, and preserve the jawbone's shape and adjacent important structures. Currently, three main treatment methods are used clinically: pocket suture / fenestration decompression, cyst curettage, and radical excision.

[0003] Fenestration decompression, which maintains a passage between the cyst cavity and the oral cavity, releases intracystic pressure, promotes cyst shrinkage and bone regeneration, and is suitable for cases with larger cysts or those adjacent to important anatomical structures. However, most of the cyst wall remains inside the body during this treatment; therefore, the pathological nature of the lesion must be determined before surgery or treatment to ensure that the indications for fenestration decompression are met.

[0004] Several improved fenestration drainage devices have emerged in the current technology, such as one-way valve negative pressure drainage devices and self-tapping drainage needles. However, these devices mainly serve the fenestration or continuous drainage process and do not have the function of simultaneous biopsy. Clinically, doctors often need to first use independent biopsy methods to obtain cyst wall tissue for pathological diagnosis, and then perform fenestration drainage after confirmation; or they can directly use curettage to obtain pathological specimens at the same time, but curettage is more invasive and not suitable for all cases. This step-by-step treatment mode of biopsy first and then fenestration leads to a longer treatment cycle, requiring patients to endure multiple procedures and waiting time, and may delay the best treatment time. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides an integrated minimally invasive diagnostic and treatment device for jawbone cyst biopsy and fenestration drainage. This integrated minimally invasive device enables simultaneous pathological sampling and self-tapping implantation, and has the advantages of being easy to operate and having high overall practicality.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An integrated minimally invasive diagnostic and treatment device for biopsy and fenestration drainage of jaw cysts includes: A biopsy assembly, the biopsy assembly including a cannula, the outside of which is provided with a blade; and A positioning sleeve has an insertion section with self-tapping threads, and the interior of the positioning sleeve has a through-type operating channel for inserting the biopsy component.

[0007] In one possible implementation, the blade is a helical blade, and the outer edge of the sleeve is provided with a helical track for the helical blade to be screwed into for assembly.

[0008] In one possible implementation, a limiting blind hole is provided inside the sleeve, and a limiting shaft is inserted into the limiting blind hole; The tail of the spiral blade is provided with a limiting hole. When the spiral blade is fully inserted into the spiral track, the limiting hole corresponds to the limiting blind hole, and the limiting shaft is inserted into the limiting hole to restrict the movement of the spiral blade.

[0009] In one possible implementation, the sleeve has an insertion end and an operating end, with the limiting shaft protruding from the operating end.

[0010] In one possible implementation, the bottom of the sleeve is provided with rounded corners.

[0011] In one possible implementation, the sleeve is provided with an operating handle, which is a frustum-shaped protrusion at the top of the sleeve.

[0012] In one possible implementation, a suction device is provided inside the sheath, the suction device includes a suction tube that is movably connected to the sheath, and the end of the suction tube is used to connect to a negative pressure device.

[0013] In one possible implementation, a filter element is disposed inside the suction tube.

[0014] In one possible implementation, a flushing and drainage assembly is also included, the flushing and drainage assembly comprising: An auxiliary retainer, wherein the auxiliary retainer is provided with an external thread, the external thread being threadedly connected to the inner wall of the sleeve; and A flushing and drainage tube is installed on the auxiliary retainer, with one end for extending into the bottom of the positioning sleeve and the other end for connecting to an external flushing and drainage device.

[0015] In one possible implementation, the end of the positioning sleeve is threaded with a sealing cap.

[0016] The present invention has the following advantages due to the adoption of the above technical solutions: Compared with existing technologies, after the positioning sleeve is inserted and the biopsy is performed, the internal operating channel of this device can become a shared channel for subsequent nursing procedures.

Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0020] Jawbone cysts are pathological cystic cavities occurring within the jawbone. Various improved fenestration drainage devices have been developed in the prior art, such as one-way valve negative pressure drainage devices and self-tapping drainage needles. However, these devices primarily serve the fenestration or continuous drainage process and do not have simultaneous biopsy capabilities. Clinically, doctors often need to first obtain cyst wall tissue through independent biopsy for pathological diagnosis, and then perform fenestration drainage after confirmation; or they can directly perform curettage to obtain pathological specimens simultaneously, but curettage is more invasive and not suitable for all cases. This step-by-step approach of biopsy first, then fenestration, leads to a prolonged treatment cycle, requiring patients to endure multiple procedures and waiting times, and may delay the optimal treatment time. To address the above technical problems, this invention provides an integrated minimally invasive diagnostic and treatment device for jawbone cyst biopsy and fenestration drainage. This integrated minimally invasive device can achieve simultaneous pathological sampling and self-tapping implantation, and has the advantages of easy operation and high overall practicality. The technical solution of this invention will be described in detail below with specific examples.

[0021] Reference Figure 1 as well as Figure 2 As shown, the present invention relates to an integrated minimally invasive diagnostic and treatment device for biopsy and fenestration drainage of jaw cysts, comprising a biopsy component 1 and a positioning sleeve 2. The biopsy component 1 includes a cannula 11, with a blade 12 disposed on the outside of the cannula 11. The positioning sleeve 2 has an insertion section 21 with self-tapping threads, and an internal through-type operating channel 22 for inserting the biopsy component 1.

[0022] It should be noted that the coordinated operation of the biopsy component 1 and the positioning sleeve 2 enables precise localization, minimally invasive implantation, and simultaneous biopsy sampling of the jawbone cyst. Specifically, the self-tapping thread design allows medical personnel to directly screw the positioning sleeve 2 into the cyst site via the jawbone or a predetermined path during clinical operation without the need for pre-drilling or additional fixation instruments. The sleeve's threads form a stable mechanical interlock with the bone wall, ensuring long-term and reliable fixation in the predetermined position. Furthermore, the positioning sleeve 2 has a through-type operating channel 22 inside, which provides a guiding path for the subsequent insertion of the biopsy component 1, ensuring that the biopsy component 1 reaches the cyst wall along a predetermined direction.

[0023] For example, when using this device, after determining the location of the cyst and the thickness of the bone wall through imaging assessment, a suitable predetermined location is selected. The insertion section 21 of the positioning sleeve 2 is aligned with the predetermined location, appropriate axial pressure is applied, and it is rotated, gradually screwed in using the self-tapping thread until the distal end of the sleeve penetrates the cyst wall and enters the cyst cavity. At this point, the positioning and installation of the positioning sleeve 2 is complete. During biopsy, the biopsy component 1 is inserted into the cyst cavity through the operating channel 22 of the positioning sleeve 2. Under imaging or tactile guidance, cyst wall tissue is excised, and then the biopsy component 1 is removed. The specimen is then sent for examination, thus completing the biopsy operation. If subsequent fenestration and drainage care is required, it is also performed through the operating channel 22 within the positioning sleeve 11.

[0024] Compared with existing technologies, after the positioning sleeve 2 is inserted and the biopsy is performed, the internal operating channel 22 of this device can become a shared channel for subsequent nursing operations. Medical staff can use the operating channel 22 to perform biopsy sampling and fenestration drainage, thereby avoiding secondary punctures or surgeries for the patient and significantly shortening the operation time and the patient's postoperative recovery period. The device can achieve simultaneous pathological sampling and self-tapping implantation, and has the advantages of being easy to operate and having high overall practicality.

[0025] In one embodiment, more preferably, the blade 12 is a helical blade, and the outer edge of the sleeve 11 is provided with a helical track 111 for the helical blade to be screwed in for assembly.

[0026] It should be noted that when using a spiral blade for biopsy, the blade contacts the cyst wall tissue in a continuous and gradual manner, rather than in a single impact or tear, thus producing tissue strips of uniform thickness and complete shape, which facilitates subsequent pathological inference.

[0027] In this embodiment, the positioning structure of the spiral blade is further refined. A limiting blind hole is provided inside the sleeve 11, and a limiting shaft 13 is inserted into the limiting blind hole. Simultaneously, a limiting hole is provided at the tail of the spiral blade. When the spiral blade is fully inserted into the spiral track 111, the limiting hole corresponds to the limiting blind hole, and the limiting shaft 13 is inserted into the limiting hole to restrict the movement of the spiral blade. Specifically, the sleeve 11 has an insertion end and an operating end, with the limiting shaft 13 protruding from the operating end.

[0028] It should be noted that, through this positioning structure, when the spiral blade is fully screwed into the spiral track 111, the limiting hole and the limiting blind hole are perfectly aligned. At this point, inserting the limiting shaft 13 achieves both axial and circumferential locking between the blade 12 and the sleeve 11, preventing accidental loosening or displacement of the blade 12 during use and improving the stability of the spiral blade 12. Simultaneously, the detachable structure of the blade 12 facilitates the removal of cut tissue by medical personnel, providing convenience for subsequent operations.

[0029] In some embodiments, the structure of the sleeve 11 is further refined. To avoid damage to the tissue from the outer edge of the sleeve 11, a rounded corner is provided at the bottom of the sleeve 11.

[0030] In addition, to facilitate the operation of the biopsy component 1 by medical staff, an operating handle 14 is provided on the cannula 11. The operating handle 14 is a frustum-shaped protrusion on the top of the cannula 11.

[0031] Reference Figure 3 As shown, in one embodiment, more preferably, a suction device 15 is provided inside the sleeve 11. The suction device 15 includes a suction tube, which is movably connected to the sleeve 11. The end of the suction tube is used to connect to a negative pressure device.

[0032] It should be noted that in some scenarios, the patient's cyst wall is mobile. In particular, if the cyst is punctured and the fluid leaks out, the position of the cyst wall will change. When using the biopsy component 1 to cut directly, the cyst wall may shake, making it impossible to cut. In this case, medical staff can use the biopsy component 1 with suction device 15. When taking a biopsy, connect a negative pressure device to the suction tube. While holding the cannula 11, move the suction tube to suction the cyst wall. Then, manipulate the cannula 11 to cut with the blade 12.

[0033] The movable connection design between the suction tube and the cannula 11 allows medical staff to effectively address the operational difficulties caused by cyst wall movement, significantly improving the success rate of biopsies, specimen quality, and surgical safety, especially suitable for patients with loose cyst walls. Furthermore, in this embodiment, a filter is installed inside the suction tube to prevent the aspiration of other substances.

[0034] Reference Figure 4 As shown, in one embodiment, more preferably, to further facilitate subsequent nursing procedures, the device also provides a set of replaceable nursing components. After completing the biopsy procedure, medical personnel can insert the irrigation and drainage component 3 into the operating channel 22 for subsequent irrigation and drainage care.

[0035] The flushing and drainage assembly 3 includes an auxiliary retainer 31 and a flushing and drainage tube 32. The auxiliary retainer 31 is provided with an external thread, which is connected to the inner wall of the sleeve 11. The flushing and drainage tube 32 is inserted through the auxiliary retainer 31, with one end for extending into the bottom of the positioning sleeve 2 and the other end for connecting to an external flushing and drainage device.

[0036] It should be noted that the irrigation and drainage component 3 is selected as an optional component to switch the device from biopsy mode to treatment and care mode after the cyst wall biopsy is completed and the pathological diagnosis is confirmed. The external thread of the auxiliary fixator 31 is used to form a threaded connection with the inner wall of the operating channel 22 of the positioning sleeve 2, thereby stably fixing the irrigation and drainage tube 32 in the positioning sleeve 2 and preventing the irrigation and drainage tube 32 from shifting or falling out. One end of the irrigation and drainage tube 32 extends into the bottom of the positioning sleeve 2 to reach the inside of the cyst cavity, and the other end is connected to an external irrigation and drainage device, such as a syringe or irrigation pump. After the biopsy component 1 is removed, there is no need to remove the implanted positioning sleeve 2. The irrigation and drainage component 3 can be directly inserted after removing the biopsy component 1 to establish an irrigation channel, avoiding secondary surgical trauma.

[0037] In one embodiment, more preferably, a sealing cap 23 is threadedly connected to the end of the positioning sleeve 2.

[0038] In traditional fenestration decompression surgery, an open or semi-open channel exists between the sac cavity and the oral cavity. When the patient eats, food residue easily enters this channel and the sac cavity, causing putrefaction, unpleasant odors, and bacterial growth, leading to recurrent infections and impacting normal social life. This implementation method uses a sealing cap 23 at the end of the positioning sleeve 2, allowing the patient to tighten and loosen it independently. The threaded connection provides excellent sealing and prevents detachment during daily activities. The sealing cap 23 completely seals during non-drainage and non-irrigation periods, effectively preventing food residue, saliva, and oral microorganisms from entering the drainage channel, minimizing disruption to the patient's daily life while ensuring treatment effectiveness.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
