Description

Technical Field

[0001] This invention belongs to the field of medical auxiliary device technology, and more specifically, relates to a soft palate protection device for oral and nasal skull base surgery. Background Technology

[0002] In the field of head and neck surgery, especially in transoral nasopharyngeal, oropharyngeal, parapharyngeal, and skull base surgeries, a clear surgical field and precise surgical technique are crucial for surgical success. In these surgeries, lifting the soft palate is key to ensuring sufficient surgical space and avoiding damage to surrounding structures (especially the uvula). However, the commonly used method in current clinical practice, namely using a catheter to suspend the soft palate, has significant shortcomings. This method not only causes local congestion or ischemia of the soft palate due to compression, leading to postoperative soft palate dysfunction such as dysphagia and speech disorders, but also fails to effectively protect the uvula. Damage to the uvula can seriously affect the patient's speech quality. Given the importance of postoperative soft palate function recovery for patients' quality of life, it is particularly important to develop a new type of soft palate protector. This protector should safely and effectively protect the soft palate, reduce surgical damage to the soft palate and its surrounding structures, and be easy to operate, thereby improving surgical safety, reducing postoperative complications, and accelerating the patient's postoperative functional recovery.

[0003] Therefore, researching and developing a soft palate protection device for transoral and nasal skull base surgery is of urgent need and far-reaching significance for patients undergoing head and neck surgery. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a soft palate protection device for transoral and nasal skull base surgery.

[0005] A soft palate protection device for transoral and nasal skull base surgery includes a soft palate protective sleeve body;

[0006] The lower end of the soft palate protective sleeve body is fixedly installed with a traction protection structure;

[0007] The traction protection structure includes a first traction band, a second traction band fixedly installed at the lower end of the soft palate protective sleeve body, a first through groove and a second through groove penetrating the interior of the soft palate protective sleeve body, a third traction band inside the first through groove, a first flat connector fixedly installed at the upper end of the third traction band, a first fixing buckle fixedly installed at the upper end of the first flat connector, a fourth traction band inside the second through groove, a second flat connector fixedly installed at the upper end of the fourth traction band, and a second fixing buckle fixedly installed at the upper end of the second flat connector, both the first flat connector and the second flat connector being located inside the first and second through grooves, and the first and second through grooves being located on the side of the soft palate protective sleeve body away from the first and second traction bands.

[0008] Preferably, the first, second, third, and fourth traction straps are made of silicone, the soft palate protective sleeve body is made of silicone, the first fixing buckle is flat, the second fixing buckle is flat, the diameter of the first fixing buckle is larger than the inner diameter of the first through groove, and the diameter of the second fixing buckle is larger than the inner diameter of the second through groove.

[0009] Preferably, a first tether is fixedly installed on the side wall of the first traction band, a second tether is fixedly installed on the side wall of the second traction band, a third tether is fixedly installed on the side wall of the third traction band, and a fourth tether is fixedly installed on the side wall of the fourth traction band. The soft palate protective sleeve body has a groove inside and the soft palate protective sleeve body is arc-shaped.

[0010] Preferably, the diameters of the first, second, third, and fourth traction bands are all 2 mm, the thickness of the soft palate protective sleeve body is 2 mm, the width of the soft palate protective sleeve body is 2 mm, and the length of the soft palate protective sleeve body is 5 cm.

[0011] A method of using a soft palate protection device in transoral and nasal skull base surgery includes the following steps:

[0012] S1, Step 1: When using this device, the staff first picks up the third and fourth traction straps, applies the protective liquid evenly to the surface of the third and fourth traction straps, and then carefully inserts the end of the third and fourth traction straps with the first and second fixing buckles into the patient's nasal cavity with the help of a special tool and pushes it continuously until the end of the third and fourth traction straps with the first and second fixing buckles reaches the patient's nasopharynx or oropharynx. Then, the staff uses polyp forceps to gently and slowly pull the third and fourth traction straps located in the nasopharynx or oropharynx out of the patient's mouth. At the same time, ensure that the end of the third and fourth traction straps away from the first and second fixing buckles is left with a certain length outside the patient's nasal cavity, and ensure that the third and fourth ligatures are located outside the patient's nasal cavity and do not enter the patient's nasal cavity.

[0013] S2, then, the staff evenly applied lubricant to the first traction strap, the second traction strap, and the soft palate protective sleeve body, so that the soft palate protective sleeve body was covered with an appropriate amount of liquid. After that, the first fixing buckle and the second fixing buckle exposed outside the patient's oral cavity can be inserted into the first through groove and the second through groove on the soft palate protective sleeve body respectively, and exposed on the other side surface of the soft palate protective sleeve body, thereby completing the connection between the first traction strap and the second traction strap and the soft palate protective sleeve body.

[0014] S3. Subsequently, the staff can slowly pull the third and fourth traction straps exposed outside the patient's nasal cavity towards the outer side of the nasal cavity. This allows the third and fourth traction straps to generate radial force, pulling the soft palate protector body and the first and second traction straps on the soft palate protector body into the patient's oral cavity until the soft palate protector body precisely reaches the soft palate position between the patient's nasal cavity and oral cavity. At this point, the first and second traction straps on the soft palate protector body should have a reserved length at the tail of the patient's oral cavity. Simultaneously, the third and fourth traction straps on the first and second traction straps... The first and second ligatures should be located outside the patient's mouth. Finally, the staff slightly pulls the first, second, third, and fourth traction straps away from the nasal cavity to generate radial force, creating appropriate tension on the soft palate protector body, thereby smoothly lifting and wrapping the soft palate. After completing the above operations, the staff properly knots and secures the first and third ligatures on the first and third traction straps outside the patient's nasal cavity and mouth, as well as the second and fourth ligatures on the second and fourth traction straps. This completes the entire operation.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In this invention, by setting up a traction protection structure, the operator can use the first, second, third, and fourth traction straps to move the soft palate protector body to the soft palate position between the patient's nasal cavity and oral cavity. Then, the operator can slightly pull the first, second, third, and fourth traction straps in the direction of the nasal cavity to create appropriate tension on the soft palate protector body, so as to smoothly lift and wrap the soft palate, effectively achieving the purpose of lifting the soft palate, protecting the soft palate and uvula, and effectively reducing unnecessary contact with surgical instruments or examination tools, reducing the risk of tissue damage. At the same time, it is also conducive to smoother operation of instruments in the channel between the nasal cavity and oral cavity, improving the convenience and efficiency of operation.

[0017] In this invention, by opening a first through groove and a second through groove on the soft palate protective sleeve body respectively, and by setting a first fixing buckle and a second fixing buckle on the third traction strap and the fourth traction strap, the first fixing buckle and the second fixing buckle are made of rubber material and are flat, making the overall structure material relatively soft and able to snap into the first through groove and the second through groove. This combination of the two can further reduce the thickness of the traction protective structure on the basis of making it detachable, thereby alleviating the discomfort caused by the protective structure when operating between the patient's oral cavity and nasal cavity and improving comfort.

[0018] In this invention, by setting a first traction band, a second traction band, a third traction band, and a fourth traction band on the soft palate protective sleeve body, and applying a protective liquid before inserting it into the patient's oral cavity, the friction between the soft palate protective sleeve body, the first traction band, the second traction band, the third traction band, and the fourth traction band and the oral cavity is reduced, allowing the soft palate protective sleeve body to enter the nasal cavity more smoothly, reducing discomfort and improving safety.

[0019] In this invention, by creating a groove inside the soft palate protector body, a portion of the protective fluid can be temporarily stored in the groove. When the staff uses the traction protective structure to insert it into the patient's mouth, the stored fluid can slide due to the gravity of the soft palate protector body during movement, reducing the friction between the traction protective structure and the patient's skin tissue and further improving comfort.

[0020] In this invention, by inserting the first fixing buckle and the second fixing buckle into the first through groove and the second through groove and exposing the first fixing buckle and the second fixing buckle on the other side of the soft palate protective sleeve body, the third traction strap and the fourth traction strap can be assembled and connected, thereby allowing for individual replacement and improving maintainability.

[0021] In this invention, by making the soft palate protective sleeve body, the first traction band, the second traction band, the third traction band, the fourth traction band, the first fixing buckle, and the second fixing buckle into silicone material, the traction protection structure can maintain its structural integrity in the complex chemical environment of the oral cavity and nasal cavity, avoiding corrosion of the traction protection structure due to the presence of various electrolytes, enzymes, and microorganisms in saliva in the oral cavity and secretions in the nasal cavity, thus improving reliability.

[0030] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0031] Please see Figure 1 - Figure 7 The present invention provides a soft palate protection device for oral and nasal skull base surgery, including a soft palate protection sleeve body 11;

[0032] A tension protection structure is fixedly installed at the lower end of the soft palate protective sleeve body 11;

[0033] The traction protection structure includes a first traction strap 12, a second traction strap 13 fixedly installed at the lower end of the soft palate protective sleeve body 11, a first through groove 14 and a second through groove 15 extending through the interior of the soft palate protective sleeve body 11, a third traction strap 16 inside the first through groove 14, a first flat connector 17 fixedly installed at the upper end of the third traction strap 16, a first fixing buckle 18 fixedly installed at the upper end of the first flat connector 17, and a fourth traction strap 19 inside the second through groove 15. By setting up the traction protection structure, staff can use the first traction strap 12, the second traction strap 13, the third traction strap 16, and the fourth traction strap 19 to move the soft palate protective sleeve body 11 to the soft palate position between the patient's nasal cavity and oral cavity. Then, staff can slightly pull it in the lateral direction of the nasal cavity. The first traction band 12, the second traction band 13, the third traction band 16, and the fourth traction band 19 create appropriate tension in the soft palate protective sleeve body 11, smoothly lifting and wrapping the soft palate. This effectively lifts and protects the soft palate and uvula, while also reducing unnecessary contact with surgical instruments or examination tools, lowering the risk of tissue damage. It also facilitates smoother instrument operation within the passage between the nasal cavity and oral cavity, improving operational convenience and efficiency. By inserting the first fixing buckle 18 and the second fixing buckle 22 into the first through groove 14 and the second through groove 15, and exposing the first fixing buckle 18 and the second fixing buckle 22 on the other side of the soft palate protective sleeve body 11, the third traction band 16 and the fourth traction band 19 can be assembled and connected, allowing for individual replacement and improving maintainability.

[0034] A second flat connector 21 is fixedly installed at the upper end of the fourth traction strap 19. A second fixing buckle 22 is fixedly installed at the upper end of the second flat connector 21. The first flat connector 17 and the second flat connector 21 are both located inside the first through groove 14 and the second through groove 15. The first through groove 14 and the second through groove 15 are located on the side of the soft palate protective sleeve body 11 away from the first traction strap 12 and the second traction strap 13. The second fixing buckle 22 is flat. The diameter of the first fixing buckle 18 is larger than the inner diameter of the first through groove 14, and the diameter of the second fixing buckle 22 is larger than the inner diameter of the second through groove 14. The inner diameter of the through groove 15, the first fixing buckle 18 and the second fixing buckle 22 are made of rubber. By making the soft palate protective sleeve body 11, the first traction band 12, the second traction band 13, the third traction band 16, the fourth traction band 19, the first fixing buckle 18 and the second fixing buckle 22 made of silicone, the traction protection structure can maintain its structural integrity in the complex chemical environment of the oral cavity and nasal cavity. This avoids corrosion of the traction protection structure due to the presence of various electrolytes, enzymes and microorganisms in saliva in the oral cavity and secretions in the nasal cavity, thus improving reliability.

[0035] The first traction band 12, the second traction band 13, the third traction band 16, and the fourth traction band 19 are made of silicone. The soft palate protective sleeve body 11 is also made of silicone. The first fixing buckle 18 is flat. By opening the first through groove 14 and the second through groove 15 on the soft palate protective sleeve body 11 respectively, and by setting the first fixing buckle 18 and the second fixing buckle 22 on the third traction band 16 and the fourth traction band 19 to be made of rubber, and by making the first fixing buckle 18 and the second fixing buckle 22 flat, the overall structure material is relatively soft and can be snapped into the first through groove 14 and the second through groove 15. This combination allows for further reduction of the thickness of the traction protection structure while making it detachable, thereby alleviating the discomfort caused by the protective structure when operating between the patient's oral cavity and nasal cavity and improving comfort.

[0036] A first tether 23 is fixedly installed on the side wall of the first traction strap 12, a second tether 24 is fixedly installed on the side wall of the second traction strap 13, a third tether 25 is fixedly installed on the side wall of the third traction strap 16, and a fourth tether 26 is fixedly installed on the side wall of the fourth traction strap 19. A groove 27 is provided inside the soft palate protective sleeve body 11. The soft palate protective sleeve body 11 is arc-shaped. By opening the groove 27 inside the soft palate protective sleeve body 11, the groove 27 can temporarily store some protective fluid. When the staff uses the traction protective structure to insert into the patient's mouth, the gravity of the soft palate protective sleeve body 11 during movement can allow the temporarily stored fluid to slide, reducing the friction between the traction protective structure and the patient's skin tissue and further improving comfort.

[0037] Working principle:

[0038] The first step, when using the device, is for the operator to pick up the third traction strap 16 and the fourth traction strap 19, and evenly apply a protective liquid (such as a polyethylene glycol solution, sodium carboxymethyl cellulose solution, or other lubricating solution) to the surfaces of the third traction strap 16 and the fourth traction strap 19. Then, using a special tool, carefully insert the end of the third traction strap 16 and the fourth traction strap 19 with the first fixing buckle 18 and the second fixing buckle 22 into the patient's nasal cavity and continue pushing until the third traction strap 16 and the fourth traction strap 19 are fully inserted. One end of the first fixing buckle 18 and the second fixing buckle 22 reaches the patient's nasopharynx or oropharynx. Then, the staff uses polyp forceps to gently pull the third traction band 16 and the fourth traction band 19 located in the nasopharynx or oropharynx out of the patient's mouth. At the same time, it is ensured that the ends of the third traction band 16 and the fourth traction band 19 away from the first fixing buckle 18 and the second fixing buckle 22 are left with a certain length outside the patient's nasal cavity. It is also necessary to ensure that the third tether 25 and the fourth tether 26 are located outside the patient's nasal cavity and do not enter the patient's nasal cavity.

[0039] The second step involves the staff applying lubricant evenly to the first traction strap 12, the second traction strap 13, and the soft palate protective sleeve body 11, so that the soft palate protective sleeve body 11 is coated with an appropriate amount of liquid. Then, the first fixing buckle 18 and the second fixing buckle 22, which are exposed outside the patient's oral cavity, can be inserted into the first through groove 14 and the second through groove 15 on the soft palate protective sleeve body 11, respectively, and exposed on the other side surface of the soft palate protective sleeve body 11, thereby completing the connection between the first traction strap 12 and the second traction strap 13 and the soft palate protective sleeve body 11.

[0040] Thirdly, the staff can then slowly pull the third traction band 16 and the fourth traction band 19 exposed outside the patient's nasal cavity towards the outer side of the nasal cavity. This allows the third traction band 16 and the fourth traction band 19 to generate radial force, pulling the soft palate protective sleeve body 11 and the first traction band 12 and the second traction band 13 on the soft palate protective sleeve body 11 into the patient's oral cavity until the soft palate protective sleeve body 11 precisely reaches the soft palate position between the patient's nasal cavity and oral cavity. At this point, the first traction band 12 and the second traction band 13 on the soft palate protective sleeve body 11 should leave a certain length at the tail of the patient's oral cavity. At the same time, the first tether 23 and the second tether 24 on the first traction band 12 and the second traction band 13 should be in place. 4. The first traction band 12, the second traction band 13, the third traction band 16, and the fourth traction band 19 should be located outside the patient's oral cavity. Finally, the staff should slightly pull the first traction band 12, the second traction band 13, the third traction band 16, and the fourth traction band 19 away from the nasal cavity to generate radial force. This will create appropriate tension in the soft palate protective sleeve body 11, thereby smoothly lifting and wrapping the soft palate, effectively achieving the purpose of lifting the soft palate, protecting the soft palate and uvula. After completing the above operations, the staff should properly tie and fix the first ligature 23 and the third ligature 25 on the first traction band 12 and the third traction band 16 outside the patient's nasal cavity and oral cavity, as well as the second ligature 24 and the fourth ligature 26 on the second traction band 13 and the fourth traction band 19. This completes the entire operation process.
