[0032] The utility model relates to the technical field of plastic surgery instruments, and in particular to an adjustable nasal cavity stretcher for plastic surgery. The purpose is to solve the problem that in the prior art, nasal cavity stretchers of various specifications and models need to be prepared to meet the needs of patients during the recovery period, but the use time of preparing nasal cavity stretchers of various specifications and models during the recovery period is short, and after use, multiple nasal cavity stretchers can only be discarded, which wastes resources. In addition, due to differences in human bodies, the existing nasal cavity stretchers of fixed sizes are not suitable for all patients, and cannot better meet the personalized needs of patients, and some patients cannot use them. To this end, the utility model provides an adjustable nasal stretching device for plastic surgery, including a nasal stretching mechanism, which includes a support rod, a stretching drive assembly and a stretcher, the stretcher including a plurality of stretching flaps, which are arranged in a circular array on the support rod, and the stretching drive assembly is sleeved on the support rod.

There is no need to prepare nasal stretchers of various specifications and types, thereby avoiding waste and reducing operations.

[0033] The adjustable nasal cavity stretching device for plastic surgery provided by the embodiment of the utility model is described in detail below with reference to the accompanying drawings.

[0034] See also Figure 1 , Figure 2 and Figure 5 The utility model provides an adjustable nasal cavity stretching device for plastic surgery, the nasal cavity stretching device includes a nasal cavity stretching mechanism, the nasal cavity stretching mechanism includes a support rod 1, a stretching drive assembly 2 and a stretcher 3, the stretcher 3 includes a plurality of stretching petals 301, the plurality of stretching petals 301 are arranged on the support rod 1 in a circular array, the stretching drive assembly 2 is sleeved on the support rod 1, and the stretching drive assembly 2 drives the plurality of stretching petals 301 to move up and down in a forward and reverse rotation manner to expand outward or contract inward.

[0035] In one embodiment, see Figure 1-2 The number of nasal cavity opening mechanisms is two, and one end of the support rod 1 in the two nasal cavity opening mechanisms is fixedly connected by a connecting rod 4. The support rod 1 and the connecting rod 4 can be an integrated structure. When there are two nasal cavity opening mechanisms, it is convenient to open the two nasal cavities of the nose at the same time.

[0036] In one embodiment, see Figure 5 , a plurality of expanded petals 301 form a conical structure, and the cross section of the expanded petals 301 is an arc shape.

[0037] In one embodiment, adjacent petals 301 are connected by a flexible member. The flexible member is flexible, such as silicone, and the silicone and the edge of the petal 301 can be fixed by bonding. The provision of the flexible member can ensure that the plurality of petals 301 are connected to each other, and also ensure that the adjacent petals 301 do not affect each other when expanding or contracting.

[0038] In one embodiment, see Figure 2 and Figure 4 The expansion drive assembly 2 includes a drive tube 202 and a drive platform 201. The drive tube 202 is sleeved on the support rod 1 and threadedly connected thereto. One end of the drive tube 202 is rotatably connected to the drive platform 201. The interior of the drive platform 201 is a hollow structure so as to be sleeved on the support rod 1. The drive tube 202 drives the drive platform 201 to move forward or backward along the axial direction of the support rod 1 in a forward and reverse rotation manner to drive the multiple expansion petals 301 to move up and down to expand outward or contract inward.

[0039] Specifically, the support rod 1 is provided with a thread, and the inner wall of the driving tube 202 is provided with a thread sleeve on the support rod 1 and threadedly connected, so that when the driving tube 202 is rotated, the driving tube 202 is moved forward or backward along the axis direction of the support rod 1 during the forward and reverse rotation through the thread structure. There are many ways of rotationally connecting one end of the driving platform 201 and the driving tube 202. For example, the driving tube 202 and the driving platform 201 are rotationally connected by a bearing. Therefore, without deviating from the basic principle of the utility model, it is flexibly set according to the actual use situation.

[0040] In addition, the present application does not make any specific limitation on the specific shape of the driving platform 201. For example, the driving platform 201 is a conical frustum structure. The interior of the driving platform 201 is designed to be a hollow structure so that it can be sleeved on the support rod 1. The inner diameter of the driving platform 201 can be larger than the diameter of the support rod 1.

[0041] In one embodiment, see Figure 4 The driving platform 201 is provided with a plurality of through holes 2011 distributed in a circular array and connected to the interior, the number of the through holes 2011 is the same as the number of the expanded petals 301, the side walls of the through holes 2011 away from the driving tube 202 are open structures, and inclined slide grooves 2012 are respectively provided on the two side walls in the through holes 2011, and the expanded petals 301 are slidably connected with the slide grooves 2012. When the driving platform 201 drives the slide grooves 2012 to move relative to the expanded petals 301, the expanded petals 301 can move up and down.

[0042] Specifically, the angle between the center line of the slide groove 2012 in the length direction and the axis of the driving platform 201 is 30° to 45°. Figure 4As shown, when the driving tube 202 drives the driving platform 201 to move forward, the slide groove 2012 acts on the open petals 301 to move it upward, so that the multiple open petals 301 expand outward at the same time. When the driving tube 202 drives the driving platform 201 to move backward, the slide groove 2012 acts on the open petals 301 to move it downward, so that the multiple open petals 301 contract inward at the same time, thereby realizing the function of adjusting the size of the open petals. In addition, the side wall of the through hole 2011 away from the driving tube 202 is set as an open structure, so that the limiting sleeve 302 and the limiting rod 101 can enter the through hole 2011 from the opening, thereby ensuring that the limiting sleeve 302 and the limiting rod 101 do not hinder the movement of the driving platform 201. Of course, both side walls of the through hole 2011 can be set as an open structure, that is, in a U-shape, such as Figure 4 As shown, in this case, a connecting pipe is fixed to one end of the driving platform 201 close to the driving tube 202, and the connecting pipe is rotatably connected to the driving tube 202, thereby ensuring that the driving platform 201 will not fall apart due to the through hole 2011.

[0043] In one embodiment, see Figure 5 A limiting sleeve 302 is fixed on the inner wall of the expanded petal 301, and a plurality of limiting rods 101 distributed in a circular array are fixed on the support rod 1. The limiting sleeve 302 is sleeved on the limiting rod 101 so that the expanded petal 301 can only move up and down relative to the support rod 1, and the bottom end of the limiting sleeve 302 and the limiting rod 101 are both inserted into the through hole 2011 through the opening structure.

[0044] In the above embodiment, due to the provision of the through hole 2011, the limiting rod 101 does not hinder the forward and backward movement of the driving platform 201 along the axial direction of the support rod 1. A movable connection can be adopted between the limiting sleeve 302 and the limiting rod 101 so that the limiting sleeve 302 can move up and down relative to the limiting rod 101 without being separated. For example, two evenly distributed strip holes are provided on the side wall of the limiting sleeve 302, and two guide columns are detachably fixed on the limiting rod 101. When the limiting sleeve 302 is sleeved on the limiting rod 101, the guide columns pass through the adjacent strip holes. In this way, the limiting sleeve 302 and the limiting rod 101 cannot be separated due to the restriction of the guide columns, thereby ensuring the stability of the overall structure.

[0045] In one embodiment, the cross-sections of the limiting sleeve 302 and the limiting rod 101 are both rectangular, which can prevent the limiting sleeve 302 from rotating, thereby preventing the open petal 301 from rotating, and ensuring that the open petal 301 can only move up and down. Of course, this is just an example, and the cross-section can also be a pentagon or a triangle, etc., which are all within the protection scope of this application.

[0046] In one embodiment, see Figure 5Two symmetrically distributed slide bars 303 are fixed to the bottom of the outer wall of the limiting sleeve 302, and the slide bars 303 are slidably connected with the slide groove 2012. Specifically, the slide bars 303 are inserted into the slide groove 2012, which can not only move the open petal 301 up and down, but also keep the open petal 301 and the support rod 1 from being separated.

[0047] In one embodiment, the limiting sleeve 302 is fixed to the middle part of the inner wall of the expansion flap 301, and the angle between the center line of the limiting sleeve 302 and the center line of the length direction of the expansion flap 301 is 60° to 80°.

[0048] The working principle of the utility model is as follows: the driving tube 202 is manually driven to rotate so that the driving platform 201 moves forward along the axial direction of the support rod 1. During the movement, the slide groove 2012 on the driving platform 201 moves relative to the slide rod 303. Since the slide groove 2012 is inclined, the slide rod 303 can be driven to drive the expansion petal 301 to move upward during the movement, so that multiple expansion petals 301 expand outward at the same time during the forward movement of the driving platform 201. If the driving tube 202 is rotated in the opposite direction, the driving platform 201 will be driven to move backward along the axial direction of the support rod 1. In this way, during the movement of the slide groove 2012, the slide rod 303 will be driven to drive the expansion petal 301 to move downward, so that multiple expansion petals 301 will contract inward at the same time during the backward movement of the driving platform 201. The function of adjusting the expansion size of the expander 3 is realized by expanding outward or contracting inward.

[0049] In the various embodiments described above, the present application drives the driving platform forward or backward along the axial direction of the support rod by rotating the driving tube. During the movement, the driving platform drives multiple opening flaps to move up or down at the same time, thereby realizing the function of the opener to expand outward or contract inward, thereby realizing the function of adjusting the opening size of the nasal opening device. It is suitable for different patients and can be adjusted in real time according to the patient's recovery condition during the patient's recovery period. There is no need to prepare nasal opening devices of various specifications and types, thereby reducing operations. At the same time, the nasal opening device can be reused after disinfection and sterilization after use, thereby avoiding waste of consumables. At the same time, the driving tube is threadedly connected to the support rod, and the driving platform can be moved forward or backward by rotating the driving tube. The operation is simple and convenient.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the utility model.
