A conformal hollow tube for nasal packing

technical field

The utility model relates to a conformable hollow tube, in particular to a conformal hollow tube used for nasal packing, belonging to the technical field of medical instruments.

Background technique

Nosebleeds are one of the common emergencies in otolaryngology, and timely hemostasis is required. After sinus surgery, hemostatic therapy is also required due to oozing blood from the surgical cavity. Due to the complex and irregular structure of the nasal cavity and paranasal sinuses, it is difficult to expose under direct vision.

At the end of the thin connecting pipe 5, a valve 6 for air or water is provided.

The hollow transparent tube 1 is a pressure-proof tube. Specifically, it can be a retractable threaded hose or a bendable snakeskin hose, and the anti-pressure tube can change shape with the curved nasal passage, so that it can enter and be set in the lower nasal passage for nasal ventilation and postoperative inspection.

1, 2 and 3, the hollow transparent tube 1 is worn inside the first inflatable cuff 2, and the first inflatable cuff 2 is sleeved on the cylindrical outer circumferential wall of the hollow transparent tube 1. Above, the first inflatable cuff 2 is arranged in a long strip along the direction of the hollow transparent tube 1. After the first inflatable cuff 2 is inflated or filled with water, the first inflatable cuff 2 is inflated or filled with water. The balloon 2 expands around the hollow transparent tube 1 and fills the lower nasal passage 15 . The second inflatable cuff 3 and the third inflatable cuff 4 are respectively disposed separately from the first inflatable cuff 2 . The second inflatable cuff 3 is used for filling the middle nasal passage 16 ; the third inflatable cuff 4 is used for filling the upper nasal passage and the olfactory cleft region 17 on the top of the nose.

The silicone material has good toughness and strength, which can support the cuff to the required size after the cuff is inflated or filled with water, and also ensures that the cuff is not broken by the gas or liquid filled. Attaching nanomaterials (such as nano-silver, etc.) to the outer surface of the cuff can increase the surface finish of the cuff and reduce the adsorption of scabs such as nasal scabs and blood scabs.

The following is a detailed description of the use of the conformal hollow tube for nasal packing in the surgical procedure.

Before being placed in the nasal cavity, all the inflatable cuffs are in a deflated state and attached to the outside of the hollow transparent tube 1, and the overall volume is small, which is convenient for being placed in the nasal cavity. In the process of filling the nasal cavity, align the first inflatable cuff 2 with the direction of the lower meatus, align the second inflatable cuff 3 with the direction of the middle meatus, and align the third inflatable cuff 4 with the direction of the middle meatus. Aim at the olfactory cleft area on the roof of the nose. After each cuff is placed in the corresponding position, the first inflatable cuff 2 , the second inflatable cuff 3 and the third inflatable cuff 4 are inflated or filled with water through the valve 6 and the thin connecting tube 5 . The first inflatable cuff 2, the second inflatable cuff 3, and the third inflatable cuff 4 are simultaneously inflated or inflated with water through the thin connecting tube 5 therebetween, compressing the corresponding parts and acting as conformal packing hemostatic effect. Among them, according to the needs of different operating cavities, the size and shape of the inflatable cuff can be made into several specifications: the specifications for nasal packing, the specifications for packing after sinusitis surgery, and the specifications for the lateral wall of the nasal cavity after resection. Padding specifications.

In the first embodiment provided by the present invention, after the filling is completed, if the surgical cavity needs to be inspected, a hard or soft optical fiber endoscope can be introduced into the hollow transparent tube 1, and the hard or soft optical fiber endoscope can be passed through the hard or soft optical fiber. Fiberoptic endoscopy to observe the nasal cavity and paranasal sinuses.

When the above-mentioned conformal hollow tube for nasal packing is taken out, deflation or water discharge is performed through the valve 6, the first inflatable cuff 2, the second inflatable cuff 3 and the third inflatable cuff are 4 The volume is reduced and can be removed from the nasal cavity smoothly, thereby reducing the patient's pain and the possibility of secondary bleeding.

In the second embodiment provided by the present invention, the conformable hollow tube used for nasal packing is the same as that in the first embodiment; it is only because the inferior turbinate 11 or the middle turbinate 12 is placed in the lower turbinate 11 or the middle turbinate 12 according to the actual situation of the patient during the operation. After the resection, the inferior and middle meatus in the inferior, middle, and parietal olfactory cleft areas are merged, or the middle meatus and the parietal olfactory cleft area are merged, resulting in only two areas in the nasal cavity; In addition to the first inflatable cuff 2 sheathed outside the hollow transparent tube 1, only one inflatable cuff (hereinafter referred to as the second inflatable cuff) is separately provided to meet the needs of different surgical types.

When the inferior turbinate is excised, the inferior meatus and the middle meatus are combined. At this time, the first inflatable cuff 2 sleeved outside the hollow transparent tube 1 is used to fill the combined two nasal meatus, and the second is inflatable. The cuff is used to fill the upper nasal passage and the olfactory cleft area of the nasal roof. The distance between the second inflatable cuff and the first inflatable cuff 2 is the same as the distance between the olfactory cleft region of the nose top and the inferior meatus.

When the middle turbinate is excised, the middle meatus and the olfactory cleft area of the top of the nose are combined. At this time, the second inflatable cuff set independently is used for packing the two combined nasal passages, and the first inflatable cuff is used for packing. lower nasal passages. The distance between the second inflatable cuff and the first inflatable cuff 2 is equal to the distance between the lower and middle meatus.
