Description

Technical Field

[0001] This invention relates to the field of medical assistive device technology, and in particular to a nasal cavity expansion stent and its implantation tool. Background Technology

[0002] Nasal surgeries, such as septoplasty, partial inferior turbinate resection, and nasal polyp removal, are core methods for treating structural nasal obstruction and nasal deformities. The clarity of the surgical field and the sufficiency of the operating space directly determine the surgical precision and postoperative recovery.

[0003] The commonly used metal expander in clinical practice adopts a rigid double-flap structure, which forcibly expands the nasal cavity through mechanical force. During the expansion process, the edge of the metal flap is prone to local point contact with the nasal cavity wall, with pressure as high as 50-80 kPa, which can easily lead to mucosal compression damage. Postoperative nasal adhesions or mucosal atrophy are likely to occur. In addition, the size of the expander is fixed and cannot be flexibly adjusted according to the individual differences of the patient's nasal cavity, which increases the risk of accidental damage to blood vessels or nerves during the operation.

[0004] Therefore, we propose a nasal cavity expansion stent and its implantation tool. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a nasal cavity expansion stent and its implantation tool.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A nasal cavity expansion stent and its implantation tool include a nasal cavity expansion sleeve, a hollow channel is provided through the middle of the nasal cavity expansion sleeve, an elastic airbag layer is provided at the outer end of the nasal cavity expansion sleeve, and an implantation component is provided on one side of the nasal cavity expansion sleeve.

[0008] As a further embodiment of the present invention: the implantation component includes an elastic clamp, the clamping end of the elastic clamp is provided with a clamping head, and the outer end of the clamping head is fitted with a damping silicone sleeve. The clamping head is designed to facilitate insertion into the elastic clamping sleeve, and to facilitate clamping two nasal cavity expansion sleeves at the same time.

[0009] As a further embodiment of the present invention: each end of the elastic clamp is provided with an anti-slip silicone pad, and the end of the elastic clamp away from the gripping head is provided with a hanging ring. The anti-slip silicone pads facilitate the use of the elastic clamp by medical staff, and the hanging ring facilitates the storage of the elastic clamp.

[0010] As a further aspect of the present invention: the nasal cavity dilator is provided with an elastic clamping sleeve inside, and the elastic clamping sleeve is provided with a damping silicone anti-slip layer inside. By cooperating with the clamping head and the elastic clamping sleeve, the damping silicone sleeve at the outer end of the clamping head and the damping silicone anti-slip layer inside the elastic clamping sleeve form a double anti-slip, which facilitates stable clamping and prevents slippage from affecting use.

[0011] As a further embodiment of the present invention: an inflation tube is provided at one end of the elastic airbag layer, and an inflation airbag is provided below the inflation tube. The elastic airbag layer can be inflated by pressing the inflation airbag through the inflation tube.

[0012] As a further embodiment of the present invention: the air outlet at the upper end of the inflatable airbag is provided with a connecting tube, the inflatable airbag is connected to the inflation tube through the connecting tube, and a one-way valve is provided in the middle of the connecting tube. By pressing the inflatable airbag, gas enters the elastic airbag layer through the connecting tube, the one-way valve and the inflation tube, causing the airbag layer to gradually expand, thereby opening the nasal cavity. The one-way valve prevents gas backflow and maintains stable airbag pressure.

[0013] Compared with the prior art, the present invention provides a nasal cavity expansion stent and its implantation tool, which has the following beneficial effects:

[0014] 1. In this invention, the inflatable airbag is connected to the inflation tube of the elastic airbag layer via a connecting tube. Combined with the one-way valve in the middle, it allows for step-by-step inflation, facilitating adjustment of the expansion degree as needed and preventing gas backflow. The elastic airbag layer at the outer end of the nasal cavity expands the nasal cavity through inflation. Compared to the point contact of traditional rigid metal expanders, the airbag layer forms surface contact with the nasal cavity wall, reducing contact pressure and consequently decreasing the rate of mucosal compression injury. Simultaneously, the elastic properties of the airbag can adapt to individual differences in the nasal cavities of different patients, eliminating the need to change to different sizes of instruments and reducing the risk of accidental injury to blood vessels or nerves during surgery. Through the design of the implantation components, medical personnel can use a single hand to operate the elastic clamp to grasp two nasal cavity expanders and insert them into the patient's two nasal cavities, making it quick and convenient to use and improving the practicality of the nasal cavity expander and its implantation tool.

[0015] 2. The present invention, through the hollow channel in the middle of the nasal cavity expansion sleeve, can simultaneously accommodate instruments such as nasal endoscopes and surgical forceps, avoiding mutual interference between traditional retractors and instruments; doctors do not need to repeatedly adjust the retractor or alternate instruments, the time of a single nasal surgery is reduced, the surgical efficiency is improved, and the effectiveness of the nasal cavity expansion stent and its implantation tool is enhanced.

[0016] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This invention has a simple structure and is easy to operate. Attached Figure Description

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0023] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0024] Example: Please refer to Figures 1-4 The present invention provides a technical solution:

[0025] A nasal cavity expansion stent and its implantation tool include a nasal cavity expansion sleeve 1, a hollow channel 2 penetrating through the middle of the nasal cavity expansion sleeve 1, an elastic airbag layer 3 at the outer end of the nasal cavity expansion sleeve 1, and an implantation component 4 on one side of the nasal cavity expansion sleeve 1.

[0026] In this embodiment, the preferred implantation component 4 includes an elastic clamp 41, and the clamping end of the elastic clamp 41 is provided with a clamping head 42. The outer end of the clamping head 42 is fitted with a damping silicone sleeve 43. The clamping head 42 is designed to facilitate insertion into the elastic clamping sleeve 46, and to facilitate clamping the two nasal cavity expansion sleeves 1 at the same time.

[0027] In this embodiment, preferably, each end of the elastic clamp 41 is provided with an anti-slip silicone pad 44, and the end of the elastic clamp 41 away from the gripping head 42 is provided with a hanging ring 45. The anti-slip silicone pad 44 makes it easier for medical staff to use the elastic clamp 41, and the hanging ring 45 makes it easier to store the elastic clamp 41.

[0028] In this embodiment, the nasal cavity dilator 1 preferably has an elastic clamping sleeve 46 inside, and the elastic clamping sleeve 46 has a damping silicone anti-slip layer 47 inside. The clamping head 42 cooperates with the elastic clamping sleeve 46, and the damping silicone sleeve 43 at the outer end of the clamping head 42 and the damping silicone anti-slip layer 47 inside the elastic clamping sleeve 46 form a double anti-slip, which facilitates stable clamping and prevents slippage from affecting use.

[0029] In this embodiment, preferably, an inflation tube 5 is provided at one end of the elastic airbag layer 3, and an inflation airbag 6 is provided below the inflation tube 5. The elastic airbag layer 3 can be inflated by pressing the inflation airbag 6 through the inflation tube 5.

[0030] In this embodiment, the upper air outlet of the inflatable airbag 6 is preferably provided with a connecting pipe 7. The inflatable airbag 6 is connected to the inflation pipe 5 through the connecting pipe 7. A one-way valve 8 is provided in the middle of the connecting pipe 7. By pressing the inflatable airbag 6, gas enters the elastic airbag layer 3 through the connecting pipe 7, the one-way valve 8 and the inflation pipe 5, causing the airbag layer to gradually expand, thereby opening the nasal cavity. The one-way valve 8 prevents gas backflow and maintains stable airbag pressure.

[0031] Working principle: In this embodiment, a nasal cavity expansion stent and its implantation tool are used by a medical staff member who holds the elastic clamp 41 with one hand, pinches the handle to open the two clamping heads 42 at the end, and aligns them with the elastic clamping sleeves 46 inside the two nasal cavity expansion sleeves 1 respectively. After releasing the handle, the damping silicone sleeve 43 at the outer end of the clamping head 42 and the damping silicone anti-slip layer 47 inside the elastic clamping sleeve 46 are tightly fitted to form a double anti-slip fixation, realizing the operation of clamping two expansion sleeves at one time. The connecting tube 7 of the inflatable balloon 6 is connected to the inflation tubes 5 of the two nasal cavity expansion sleeves 1 one by one, and the middle part of the connecting tube 7 is confirmed. The one-way valve 8 is closed, allowing gas to flow only from the inflatable airbag 6 to the elastic airbag layer 3, and is blocked in the reverse direction to prevent leakage during subsequent inflation. Medical staff hold the anti-slip silicone pads 44 at both ends of the elastic clamp 41 and, with the assistance of a nasal endoscope, observe through the natural nasal passage. They slowly insert the clamping head 42, which holds two nasal expansion sleeves 1, into both nasal cavities of the patient, adjusting the depth according to the location of the lesion until the expansion sleeves reach the preset expansion area. Then, the tool is temporarily suspended from the operating table hook using the hanging ring 45 at the end of the elastic clamp 41, freeing the hands for the next operation. The medical staff then press the inflation valve with one hand. Gas enters the elastic airbag layer 3 sequentially through the connecting tube 7, one-way valve 8, and inflation tube 5. After the first two to three presses, the elastic airbag layer 3 slightly inflates, initially conforming to the nasal cavity wall. The airbag is observed to ensure it is centered using a nasal endoscope. If it is misaligned, the position of the expansion sleeve is finely adjusted with forceps. Pressing continues, further inflating the airbag layer and completely opening up the narrow nasal cavity, increasing the effective airflow cross-sectional area and achieving the space required for surgical operation. After the nasal cavity is opened, the surgeon inserts instruments such as the nasal endoscope and surgical forceps into the nasal cavity through the hollow channel 2 in the middle of the nasal cavity expansion sleeve 1, performing the surgical operation under a clear view. During the procedure, the degree of expansion needs to be adjusted. The airbag 6 can be pressed to release more air, or the one-way valve 8 can be slightly turned to release a small amount of gas, flexibly adapting to the needs of the surgery. After the surgery, the one-way valve 8 is turned to release the gas in the elastic airbag layer 3 through the connecting tube 7. After the airbag layer is fully contracted, the medical staff removes the suspended elastic clamp 41, pinches the handle to open the clamp head 42, and pulls it out from the elastic clamp sleeve 46. Then, the two nasal cavity dilation sleeves 1 are slowly withdrawn from both nasal cavities. Finally, the connecting tube 7 is disconnected from the inflation tube 5, the instruments are cleaned, and the elastic clamp 41 is stored in the hanging ring 45, completing the entire surgical procedure.

[0032] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
