Description

TECHNICAL FIELD

[0001] The utility model relates to nasal cavity related disease treatment equipment technical field, especially a nasal septum suture device. BACKGROUND

[0002] Nasal septum deviation is caused by uneven development of nasal septum bones, and can also be caused by nasal trauma or nasal cavity occupying lesions, which causes the nasal septum to deviate to one side or both sides or have a local protrusion, thereby causing nasal cavity dysfunction. Depending on the type and degree of nasal septum deviation, it can cause symptoms such as nasal congestion, nosebleed, headache, and secondary sinusitis due to blocked sinus drainage. Nasal septum deviation with clinical symptoms needs to be surgically corrected.

[0003] Currently, the main hemostasis method after nasal septum correction surgery is nasal cavity packing and nasal septum suture. When the nasal septum is packed, the patient is more uncomfortable, greatly increasing the patient's pain. Therefore, the nasal septum suture scheme is gradually popularizing.

[0004] The conventional nasal septum suture method often uses a suture needle with a line and a needle holder. The specific operation method is that the operator knots the tail end of the suture needle with a line, holds the suture needle with a line with the needle holder, passes from the left (or right) nasal cavity to the right (or left) nasal cavity, then loosens the suture needle with a line with the needle holder, holds the suture needle with a line again in the right (or left) nasal cavity, and leads out, and then passes from the right (or left) nasal cavity to the left (or right) nasal cavity. Repeat the above steps to complete the single-line continuous suture.

[0005] However, the conventional suture method using a suture needle with a line and a needle holder has the following problems:

[0006] Firstly, the operator needs to loosen the suture needle with a line multiple times and make the action of holding and leading out again on the opposite side. Since the conventional suture needle with a line and the needle holder are not specifically designed for nasal septum suture, the arc angle of the suture needle with a line needs to be adjusted according to the actual situation during suture. Moreover, the needle holder is short in length and large in volume, which makes it difficult to operate flexibly in the deep and narrow nasal cavity, and the clinical suture takes a long time and has a high operation difficulty.

[0007] Secondly, the conventional suture method is single-line suture (i.e. one line completes two-sided suture, and only one side has a suture line pulling, while the opposite side has no corresponding suture line), which leads to uneven stress and insufficient pulling force, and increases the probability of postoperative bleeding or hematoma.

[0008] Therefore, it is necessary to develop a new nasal septum suture device to solve the above-mentioned problems encountered in nasal septum suture. SUMMARY

[0009] The utility model provides a nasal septum suturing device in order to solve the problems of long time consumption, great difficulty in operation, insufficient pulling force and the like in the current nasal septum suturing.

[0010] In order to achieve the above functions, the technical solution provided by the utility model is:

[0011] A nasal septum suturing device comprises a nasal septum suturing needle and a nasal septum suturing hook for use together;

[0012] The nasal septum suture needle comprises a suture needle body and a needle head; the head end of the needle head is a sharp needle tip, and the tail end is obliquely connected to the head of the suture needle body; the needle head is provided with a first thread hook and a second thread hook near the needle tip;

[0013] The nasal septum suture hook comprises a suture hook body and a hook head; the hook head is needle-shaped and vertically connected to the suture hook body.

[0014] Preferably, the angle formed by the tail of the needle head and the head of the suture needle body is 115° to 120°.

[0015] Preferably, the nasal septum suture needle further comprises a first handle arranged at the tail of the suture needle body; the nasal septum suture hook further comprises a second handle arranged at the tail of the suture hook body.

[0016] Preferably, the length of the needle head is 15 mm to 20 mm; the length of the hook head is 2 mm to 4 mm.

[0017] Preferably, the nasal septum suture device further comprises a connecting buckle, which comprises a first half ring and a second half ring connected to each other, wherein the opening directions of the first half ring and the second half ring are opposite; the first half ring and the second handle must cooperate.

[0018] Preferably, the length of the suture needle body and the suture hook body is 70 mm to 90 mm, and the diameter is 0.8 mm to 1.2 mm.

[0019] The beneficial effects of the present invention are:

[0020] First, a nasal septum suture needle and a nasal septum suture hook are provided, and the tail of the needle head of the nasal septum suture needle is obliquely connected to the head of the needle body, that is, there is a certain curvature between the needle head and the needle body. Therefore, when using the nasal septum suture needle and the nasal septum suture hook for suturing, there is no need to adjust the curvature of the suture needle, nor is there any need to repeatedly loosen the suture needle, re-clamp, and lead out the suture needle; in addition, the nasal septum suture needle and the nasal septum suture hook are long enough and small in size, and can be flexibly operated in a deep and narrow nasal cavity, thereby greatly shortening the suturing time.

[0021] Second, by setting up the nasal septum suture needle and the nasal septum suture hook, double-line suture can be achieved during suturing, and there are sutures on both sides of the suture to pull the force evenly and the pulling force is sufficient, which effectively reduces the chance of postoperative bleeding and hematoma formation.

[0028] The following is combined with Figure 1 To the attached Figure 6 The utility model is further elaborated:

[0029] A nasal septum suturing device comprises a nasal septum suturing needle 1 and a nasal septum suturing hook 2 used together.

[0030] like Figure 1 As shown, the nasal septum suture needle 1 comprises a suture needle body 11 and a needle head 12. The needle head 12 has a sharp tip 121 at its leading end, and its tail is connected to the head of the suture needle body 11 at an angle. The needle head 12 is provided with a first hook 122 and a second hook 123 near the tip 121. The suture needle body 11 is cylindrical with an outer diameter of 0.8 mm to 1.2 mm and a length of 70 mm to 90 mm. In this embodiment, the outer diameter is 1 mm and the length is 80 mm. In actual production, various specifications can be made to accommodate different patients.

[0031] Generally, the length of the needle head 12 is 15 mm to 20 mm. In this embodiment, the width of the needle head 12 is about 18 mm. An elliptical notch is provided at the lower edge of the needle head 12 to form a first wire hook 122 and a second wire hook 123. Figure 1 As shown, the openings of the first wire hook 122 and the second wire hook 123 are oriented in substantially opposite directions.

[0032] As Figure 2 shown in the figure, the nasal septum suture hook 2 comprises a suture hook body 21 and a hook head 22; the hook head 22 is needle-shaped and is connected perpendicularly to the suture hook body 21. Generally, the length of the hook head 22 is 2mm-4mm. In the embodiment, the length of the hook head 22 is 3mm.

[0033] In order to facilitate the operation of perforating and pulling the thread in the nasal cavity, the included angle between the tail of the needle head 12 and the head of the suture needle body 11 is 115º-120º. In the embodiment, the included angle is 118º.

[0034] In order to facilitate the operator to hold the nasal septum suture needle 1 and the nasal septum suture hook 2, the nasal septum suture needle 1 further comprises a first handle 13 arranged at the tail of the suture needle body 11; the nasal septum suture hook 2 further comprises a second handle 23 arranged at the tail of the suture hook body 21.

[0035] Since the operator needs to use the nasal endoscope to see the condition in the nasal cavity when the operator uses the nasal septum suture device to perform the treatment, the left hand (or the right hand) must hold the nasal endoscope and the nasal septum suture hook 2 at the same time, which is difficult to implement, therefore, the nasal septum suture device further comprises a connecting buckle, as Figure 3 shown in the figure, the connecting buckle comprises a first half ring 31 and a second half ring 32 connected to each other, the opening directions of the first half ring 31 and the second half ring 32 are opposite; the first half ring 31 is matched with the second handle 23, and the second half ring 32 is matched with the handle of the nasal endoscope. In use, the nasal septum suture hook 2 is connected to the nasal endoscope through the connecting buckle. In this way, the nasal septum suture hook 2 can be operated while holding the nasal endoscope.

[0036] The working process of the utility model is as follows:

[0037] Step 1, leading the thread: as Figure 4 shown in the figure, the operator inserts the nasal septum suture needle 1 into the right nasal cavity, perforates the nasal septum by using the needle head 12, and simultaneously passes the middle part of the suture thread through the nasal septum by using the second thread hook 123; the nasal septum suture needle 1 is inserted into the left nasal cavity, and the suture thread is led out from the left nasal cavity by using the hook head 22, and then the nasal septum suture needle 1 is withdrawn from the nasal septum;

[0038] Step 2, suturing: as Figure 5 shown in the figure, the operator uses the nasal septum suture needle 1 to pass the suture thread through the nasal septum in the right nasal cavity, and then uses the nasal septum suture hook 2 to pass the suture thread through the thread loop in the left nasal cavity, and then tightens the suture threads on both sides, so that the first needle suture is completed, and the above steps are repeated to perform continuous suture;

[0039] Step 3, knotting: as Figure 6As shown, at the end of the suturing, the operator uses the septum suture needle 1 to pass the left nasal cavity with the empty needle, places the suture thread in the left nasal cavity into the first thread hook 122 of the septum suture needle 1 through the septum suture needle 1, brings the suture thread in the left nasal cavity into the right nasal cavity through the septum suture needle 1, and then ties a knot to complete the suturing.

[0040] It should be noted that the right nasal cavity and the left nasal cavity in the above are only for convenient distinction during description, and in actual use, the two nasal cavities can be interchangeable, that is, the septum suture needle 1 can be used in the right nasal cavity or in the left nasal cavity.

[0041] The above-described embodiments are only preferred examples of the present application, and are not intended to limit the scope of the present application, so equivalent changes or modifications made according to the structure, features and principles described in the patent application range of the present application should be included in the patent application range of the present application.
