Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a nostril expansion and protection device before endoscopic nasal surgery. Background Art

[0002] During endoscopic nasal surgery, surgical instruments including scalpels, electric knives, and drills need to be repeatedly moved in and out of the nostrils. Any carelessness may cause damage or burns to the nostril opening and the skin outside the nostrils, affecting the appearance while increasing medical risks and infection risks. Scars left after surgery will affect the patient's facial appearance and may cause medical disputes. In addition, some patients with small and narrow nostrils are also prone to affecting the visual field and operational efficiency of endoscopic surgery. There are currently some nasal dilators on the market, but most of them have a single function and are made of steel. They are mainly used to expand the bilateral nasal septum mucosa and between the mucosa and the nasal septum cartilage during septoplasty. They are not suitable for endoscopic nasal surgeries other than septoplasty. Regarding the protection of the skin inside and outside the nostrils during endoscopic nasal surgery, there are currently no relevant designs on the market.

[0003] Specifically: Existing nasal dilators have a single function and are made of steel. They are only used for septum correction surgery, mainly focusing on expanding the bilateral nasal septum mucosa and between the mucosa and the nasal septum cartilage. Currently, there is no device on the market to protect the nostrils and surrounding skin during endoscopic nasal surgery, so this project has a design gap. Utility Model Content

[0004] The utility model provides a nostril expansion protection device before endoscopic nasal surgery, which fills the design gap of lack of protection for the nostril opening and surrounding skin during endoscopic nasal surgery and can provide comprehensive protection for patients during endoscopic nasal surgery.

[0006] A nostril expansion protection device for endoscopic nasal surgery includes a nostril shield with one side extending into the nostril; the nostril shield is U-shaped, and the other side of the nostril shield is provided with an upper lip shield integrally formed therewith.

[0007] Furthermore, the side of the nostril shield close to the upper lip shield has an inwardly concave tapered section.

[0008] Furthermore, the upper lip shield extends and unfolds obliquely outward in a fan shape from the tapered section.

[0009] Furthermore, the side of the nostril shield extending into the nostril has an outwardly arched expansion section.

[0010] Furthermore, the expansion section is curved near the end and transitions downward to the end.

[0011] Furthermore, the nostril shield and the upper lip shield are both soft parts.

[0012] The beneficial effects of the technical solution provided by this application are:

[0013] This nasal dilation and protection device for endoscopic nasal surgery features a U-shaped nasal shield that conforms to the natural shape of the nostrils. Its integrated upper lip shield provides additional protection for the nostrils, minimizing damage to these areas during surgical instrument movement, both in and out of the nostrils, and within the nasal cavity. This design reduces the risk of breakage and burns, minimizes local scarring, and thus protects the patient's facial aesthetics and reduces the likelihood of medical disputes.

[0018] The following will clearly and completely describe the technical solution of the present invention in conjunction with the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Reference Figure 1-2A nasal expansion and protection device for endoscopic sinus surgery includes a nasal shield 10 extending into the nostril on one side; the nasal shield 10 is "U"-shaped. The "U"-shaped structure of the nasal shield 10 enables it to fit tightly and expand the nostril and the inner wall of the nostril outward, thereby providing a wider surgical entrance, while providing stable support and protection for the inside of the nostril during the operation. This design allows surgical instruments to enter and exit the nostrils smoothly while reducing damage to the inner wall of the nostril. The other side of the nasal shield 10 is provided with an upper lip shield 20 integrally formed with it. The upper lip shield 20 is integrally formed with the nasal shield 10, which not only provides additional protection for the nostril opening, but also helps to stabilize the position of the nasal shield to ensure that it does not shift during the operation.

[0020] When surgery begins, the nostril shield 10 is first inserted into the nostril. Its U-shaped structure adapts to the shape of the nostril, providing physical support and reducing direct contact and potential damage to the nostril lining with surgical instruments. Simultaneously, the upper lip shield 20 covers the nostril opening, protecting it and the surrounding sensitive area from friction and pressure from surgical instruments. This dual protection mechanism ensures comprehensive protection of the nostrils during surgery, while also expanding the surgical field of view by opening the nostrils, improving surgical safety and efficiency.

[0021] Furthermore, the nostril shield 10 has an inwardly concave tapered section 11 on the side adjacent to the upper lip shield 20. This tapered section 11 is designed to better conform to the anatomy of the anterior nares and ergonomically. This design allows the nostril shield 10 to conform to the natural curve and shape of the nostrils, particularly the anterior nares, which are the most pronounced curvature of the nostrils, when inserted.

[0022] The tapered section 11 forms a gradual contraction by concaving inward, allowing this portion of the shield to conform more closely to the inner wall of the anterior nares. This design not only provides better physical support but also reduces pressure and friction on the inner wall of the nostrils, thereby minimizing potential damage and discomfort during surgery. Furthermore, the presence of the tapered section 11 helps improve the adaptability of the shield, allowing it to better accommodate the anatomical differences of the nostrils of different patients, ensuring smooth operation of surgical instruments while protecting the nostrils and surrounding areas from damage.

[0023] Furthermore, the upper lip shield 20 extends obliquely outward from the tapered section 11 in a fan-like shape and expands. This design allows the upper lip shield 20 to smoothly transition with the tapered section 11 of the nostril shield 10 in structure, forming a continuous protective surface that covers and protects the nostril opening and the surrounding area.

[0024] The fan-shaped design of the upper lip shield 20 provides several key functions. First, it increases the contact area with the upper lip, providing broader protection during surgery and reducing potential damage to the upper lip caused by surgical instruments. Second, this design helps stabilize the position of the nostril shield 10, preventing displacement or rotation caused by instrument manipulation during surgery. Furthermore, the fan-shaped shape helps distribute the force exerted by surgical instruments on the shield, reducing pressure on specific points and thus reducing the risk of damage to the nostril opening and surrounding skin.

[0025] Furthermore, the side of the nostril shield 10 extending into the nostril has an outwardly arched expansion section 12. This design detail is specially adapted to the internal structure of the nostril to achieve more effective nostril expansion and protection.

[0026] The arched shape of the expansion section 12 provides a gentle and steady expansion force to the inside of the nostril, thereby opening the nostril and providing ample space for surgical instruments to enter and exit. This design not only helps improve the surgical field of view, allowing the surgeon to observe and operate more clearly, but also reduces direct pressure on the inner wall of the nostril, lowering the risk of damage during surgery.

[0027] Furthermore, the arched shape of the expansion section 12 helps evenly distribute the pressure of surgical instruments on the nostrils, avoiding excessive stress concentration at a single point. This further reduces damage to the nostril lining and improves surgical safety. The design of the expansion section 12 also takes into account the diversity of nostril sizes and shapes, adapting to the individual patient's anatomy and ensuring comfort and effectiveness during surgery.

[0028] In addition, the expansion section 12 is curved near the end and transitions downward to the end. This design allows the expansion section 12 to better adapt to the anatomical structure of the nostril, especially the curved part of the nostril, when it approaches the end of the nostril.

[0029] The curved design of the expansion segment 12 helps provide more precise support and expansion within the nostril. This curved structure allows the expansion segment 12 to conform to the natural curvature of the nostril, effectively opening the nostril without damaging sensitive tissue. This not only helps maintain the nostril's open position, facilitating the manipulation of surgical instruments, but also reduces friction and pressure on the nostril's inner wall, minimizing potential damage during surgery.

[0030] Furthermore, the downward transition at the end of the expansion section 12 helps provide a smooth transition area within the nostril, further reducing the pressure on the end of the nostril and improving patient comfort. This design also helps stabilize the position of the expansion section 12 within the nostril, preventing displacement due to instrument manipulation during surgery.

[0031] The nostril shield 10 and the upper lip shield 20 are both soft parts. Soft parts mean that these parts have flexibility and plasticity and can adapt to the anatomical structures of different patients and dynamic changes during surgery.

[0032] As soft components, the nostril shield 10 and upper lip shield 20 gently contact the patient's skin and mucous membranes, reducing the discomfort and damage that can be caused by hard materials. They also prevent damage to the endoscope and surgical instruments. The use of soft materials allows for smoother insertion and removal of these shields, reducing friction on the nostril lining and upper lip area. Furthermore, the soft shields better absorb and distribute pressure that can be generated during surgery, reducing pressure on surrounding tissues, thereby reducing the risk of burns and damage and improving patient comfort.

[0033] In addition, the design of the soft parts can also achieve better sealing, avoid cross-infection during surgery, and provide a stable surgical field of view.

[0034] Soft body materials may include but are not limited to the following: 1 Medical-grade silicone: has good biocompatibility and flexibility, is easy to shape and is skin-friendly. 2 Thermoplastic elastomer: soft, heat-resistant, aging-resistant, and the hardness can be adjusted as needed. 3 Polytetrafluoroethylene: has a very low coefficient of friction, is resistant to chemical corrosion, and is often used in medical devices. 4 Polyurethane: has excellent wear resistance and flexibility, and can be used for parts that require transparent or translucent effects. 5 Polyvinyl chloride: has a low cost and is widely used in medical hoses and shields, but make sure to use medical grade to avoid toxicity.

[0035] The size should be customized according to the patient's nostril size, shape, and specific surgical requirements, or designed in multiple sizes to ensure that each patient receives personalized protection and support. These soft shields should also be designed to be easy to sterilize and reuse to meet the hygiene and cost-effectiveness requirements of the hospital environment.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
