Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically, to a stent device for endoscopic surgery of the oral and maxillofacial region. Background Technology

[0002] In recent years, with the rapid development of advanced medical devices such as endoscopic technology and high-frequency ultrasonic scalpels, and the increasing familiarity of oral and maxillofacial surgeons with the complex anatomy of the maxillofacial region and the continuous improvement of their minimally invasive concepts, more and more doctors are attempting to use the hairline approach for endoscopic-assisted resection of oral and maxillofacial tumors. This surgical method avoids surgical trauma and scarring to the facial and neck skin, enabling microscopic dissection and tumor resection of deep tissues through small incisions, thereby reducing trauma while meeting patients' high demands for cosmetic results. However, in current endoscopic-assisted surgery procedures, the surgical field exposure is often insufficient, especially in deep or narrow surgical areas. The oral and maxillofacial region is characterized by complex anatomy, narrow surgical space, and deep lesion locations, resulting in extremely high requirements for surgical field exposure in endoscopic-assisted surgery. In current techniques, surgical field exposure mainly relies on the assistant manually operating skin retractors. Although this method can expand the surgical field to some extent, the following prominent problems still exist:

[0003] 1. Exposure effectiveness is limited by the operator's skill level: The assistant needs to flexibly adjust the angle and traction force of the retractor according to the intraoperative situation, but different operators have different grasp of the force and direction, resulting in a lack of stability in the quality of surgical field exposure, which can easily affect the operator's fine operation of deep lesions.

[0004] 2. Insufficient hook stability: Oral and maxillofacial tumor resection surgery is usually time-consuming. The assistant's continuous traction on the hook can easily lead to muscle fatigue, resulting in weakened traction force or shaking, which affects the stability of the intraoperative field of vision.

[0005] 3. High risk of personnel strain: Maintaining the same posture for a long time to pull the hook can easily lead to neck and shoulder strain and hand fatigue for assistants, increasing the risk of occupational injury, and also reducing the efficiency of the entire surgical team.

[0006] Solving these problems presents significant technical challenges: on the one hand, a mechanical device capable of providing stable traction over extended periods is needed to replace continuous manual force, while also ensuring lightweight design and stability; on the other hand, the device must be adaptable to multiple angles to accommodate the complex anatomy of the maxillofacial region and the demands of various surgical positions. Furthermore, the traction head of the device must minimize pressure and damage to tissues, balancing safety and comfort.

[0007] Solving this problem has significant clinical implications: by reducing reliance on manual labor and ensuring long-term stability of the surgical field, surgical precision and efficiency can be significantly improved, and interruptions caused by adjusting retractors during surgery can be reduced, thereby shortening operation time and lowering intraoperative risks. Simultaneously, it can greatly reduce the physical burden on medical staff, lower the incidence of occupational injuries, and further promote the popularization and development of minimally invasive oral and maxillofacial surgery techniques.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example:

[0033] A stent device for endoscopic surgery of the oral and maxillofacial region, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 ,and Figure 5 As shown, it includes a base, which is U-shaped, with symmetrical supports at the top of the base. The base and supports are fixedly connected. The supports are connected to an adjustment component, which is detachably connected to a fixing component. The fixing component is detachably connected to a hook, and the adjustment component is used to adjust the angle of the hook.

[0034] The adjusting component is movably connected to the bracket. Adjusting bolts are threaded onto both ends of the adjusting component. When the adjusting bolts are screwed into the adjusting component (first connecting post and second connecting post), they press against the bracket, fixing the adjusting component in place, and can be used to adjust the height of the hook. Simultaneously, additional holes can be added to the bracket to accommodate the adjusting bolts, increasing the stability of the device.

[0035] In this embodiment, as Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the adjusting component includes a connector with an adjusting groove. The adjusting component is detachably connected to the fixed component via the adjusting groove. This detachable connection allows for flexible adjustment of the distance between the two fixed components, enabling horizontal adjustment of the hook. The adjusting component may also have anti-slip textures at both ends for easy angle adjustment.

[0036] In this embodiment, one end of the connector is rotatably connected to a first connecting post, and a damping component is provided at the connection between the connector and the first connecting post. The other end of the connector is rotatably connected to a second connecting post.

[0037] In this embodiment, a first connecting groove is provided at one end of the connector near the first connecting post, and a first disc is fixedly connected to one end of the first connecting post near the connector.

[0038] In this embodiment, the damping assembly includes a cylinder, which is fixedly connected to the first disk. Multiple sets of damping elements are provided on the outer surface of the cylinder's top end. Preferably, three or four sets are provided. In this embodiment, three sets are selected.

[0039] The damping component includes a 7-shaped post, one end of which is fixedly connected to a cylinder, and the other end of which is fixedly connected to a locking component. The locking component has external teeth on its top, and internal teeth that engage with the external teeth are provided in the first connecting groove. The 7-shaped post is made of a material with a certain degree of elasticity.

[0040] When in use, medical staff place their hands on the anti-slip texture and rotate to adjust. Under the rotational force, the locking component separates the outer teeth from the inner teeth in the first connecting groove. The locking component presses the 7-shaped post downward, causing elastic deformation. After rotating to the appropriate angle and stopping the rotation, the 7-shaped post springs back to its original shape, allowing the outer teeth of the locking component to re-engage with the inner teeth in the first connecting groove.

[0041] The outer surface of the cylinder is provided with an abutment, which is located below the engaging component. The abutment helps the engaging component and the 7-shaped column to quickly spring back to their original shape.

[0042] In addition, a straight damping shaft can also be used as the damping component.

[0043] In this embodiment, as Figure 9 As shown, the fixing component includes a first fixing post, a nut is threadedly connected to the top of the first fixing post, and a limiting ring is provided at the bottom of the first fixing post.

[0044] When in use, medical staff first insert the first fixing post into the adjustment groove, slide it to the appropriate position, and then tighten it by rotating the nut with the first fixing post. The nut and the limiting ring are used to fix it, and the connection is detachable, which makes it easy to adjust the lateral distance between the two hooks.

[0045] In this embodiment, a second fixing post is provided at the bottom of the limiting ring, a limiting hole is opened in the middle of the second fixing post, and a limiting bolt is threaded to the bottom of the second fixing post.

[0046] When in use, insert the bottom end of the hook into the limiting hole, and screw the limiting bolt into the second fixing post to contact the hook rod body to achieve limiting and fixing.

[0047] How to use

[0048] When using it, first align one end of the U-shaped opening of the base with the patient's head and place it on the operating table. Then, first unscrew the adjusting bolt, place the adjusting component at a suitable height, and then screw in the adjusting bolt. Next, adjust the lateral distance between the fixing component and the hook by using the nut in the fixing component. Finally, the angle of the hook can be adjusted by using the anti-slip rotating connector.

[0049] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
