Description

Technical Field

[0001] This utility model relates to a traction device for contracture-type nasal deformity, belonging to the technical field of medical devices. Background Technology

[0002] Contracture nasal deformity is often caused by trauma, infection, or congenital factors, and is mainly characterized by nasal alar collapse, columellar shortening, and soft tissue contracture. While traditional corrective surgery can reconstruct the nasal structure, long-term maintenance of the nasal shape is required post-surgery to prevent secondary contracture, and there is a lack of convenient and portable auxiliary treatment devices. Currently available traction devices suffer from poor linearity of tension, lack of dynamic adjustment, and limitations in three-dimensional control, failing to meet clinical needs. Therefore, the development of novel traction devices for contracture nasal deformity is of significant practical importance. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a traction device for contracture nasal deformity. The traction device for contracture nasal deformity adopts a combination of a head fixation frame and a nasal traction bracket, which can flexibly adjust the traction direction and angle, thereby effectively treating contracture nasal deformity and improving the patient's quality of life and self-confidence.

[0004] To solve the above problems, the specific technical solution of this utility model is as follows: A traction device for contracture-type nasal deformity includes a head fixation frame, a nasal traction bracket, and a nasal clip; wherein the head fixation frame is fixedly installed on the outer periphery of the patient's face, the nasal traction bracket has an inverted U-shaped structure in the middle, and both ends extend towards the head fixation frame; a positioning adjustment block is connected to the head fixation frame and the nasal traction bracket; the nasal clip is connected to the nasal clip in the middle of the nasal traction bracket by an elastic rope, and the nasal clip pulls the two sides of the patient's nasal wings.

[0005] The nose clip includes a frame, an outer clip, and an inner support; one end of the frame is a U-shaped traction end, and the other end is symmetrically provided with outer clips, which clamp on both sides of the nose; the inner support is fixedly connected to the lower part of the outer clip, and the inner support is inserted into the nostril.

[0006] The outer clip and inner support are made of medical-grade silicone and have a curved structure that conforms to the nasal tissue.

[0007] The positioning adjustment block has a cylindrical structure with two elongated holes in different directions on the cylinder. A tightening screw is provided at the elongated hole. The head fixing bracket and the nose traction bracket pass through the elongated hole at the corresponding position and are tightened and positioned in the elongated hole by the tightening screw.

[0008] The head fixation frame includes a forehead support frame, a chin support pad, a connecting frame, and a head circumference strap; the forehead support frame fits against the patient's forehead, the chin support pad fits against the patient's chin, and both sides of the forehead support frame and the chin support pad are connected to the connecting frame; the head circumference strap is connected to the connecting frames on both sides and is fixed around the head circumference by buckles.

[0009] The nasal traction bracket has two vertical positioning posts in the middle, and the middle of the positioning posts has a slot. The elastic rope is connected to the nasal traction bracket through the slot of the positioning post.

[0010] The traction device for contracture nasal deformity of this application adopts the above-mentioned structure, which enables the patient's contracture nasal deformity to be well tractioned. Its angle is adjustable and it can be worn for a long time, so that the traction force can be accurately applied to the deformed area, ensuring the stability of the traction direction and force, providing a reliable basis for the correction of nasal deformity, and helping to gradually improve the morphology of contracture nasal deformity.

[0016] like Figure 1 As shown, a traction device for contracture-type nasal deformity includes a head fixation frame 1, a nasal traction bracket 2, and a nasal clip 3. The head fixation frame 1 is fixedly installed on the outer periphery of the patient's face. The nasal traction bracket 2 has an inverted U-shaped structure in the middle, with both ends extending towards the head fixation frame 1. A positioning adjustment block 4 is connected to both the head fixation frame 1 and the nasal traction bracket 2. An elastic rope 5 is connected to the nasal clip 3 in the middle of the nasal traction bracket 2, and the nasal clip 3 pulls on both sides of the patient's nasal wings.

[0017] like Figure 2 As shown, the nose clip 3 includes a frame 3-1, an outer clip 3-2, and an inner support 3-3; one end of the frame 3-1 is a U-shaped traction end, and the other end is symmetrically provided with the outer clip 3-2, which clamps on both sides of the nose; the inner support 3-3 is fixedly connected to the lower part of the outer clip 3-2, and the inner support 3-3 is inserted into the nostril.

[0018] The outer clip 3-2 and the inner support 3-3 are made of medical-grade silicone and have a curved structure that conforms to the nasal tissue.

[0019] like Figure 4As shown, the positioning adjustment block 4 has a cylindrical structure with two elongated holes 4-1 in different directions on the cylinder. A vertical tightening screw 4-2 is located at each of the elongated holes 4-1. The head fixation frame 1 and the nasal traction bracket 2 pass through the elongated holes 4-1 at corresponding positions and are secured within the holes 4-1 by the tightening screw 4-2. The elongated holes facilitate the adjustment of the positions of the head fixation frame 1 and the nasal traction bracket 2. After adjustment, the tightening screw 4-2 secures the head fixation frame 1 and the nasal traction bracket 2 to their corresponding positions, thus enabling appropriate micro-adjustments to suit different patients' facial shapes and ensuring treatment effectiveness.

[0020] like Figure 3 As shown, the head fixation frame 1 includes a forehead support frame 1-1, a chin support pad 1-2, a connecting frame 1-3, and a head circumference strap 1-4. The forehead support frame 1-1 fits against the patient's forehead, and the chin support pad 1-2 fits against the patient's chin. Both sides of the forehead support frame 1-1 and the chin support pad 1-2 are connected to the connecting frame 1-3. The head circumference strap 1-4 is connected to the connecting frames 1-3 on both sides and is fixed around the head circumference with buckles. Only when the head fixation frame 1 is completely fixed in the patient's head position can the stability of the nasal traction bracket 2 and the nasal clip 3 be guaranteed. Therefore, the chin support pad 1-2 can ensure the stability of the vertical position of the forehead support frame 1-1, and the forehead support frame 1-1 and the head circumference strap 1-4 can ensure the stability of the front-back position of the forehead support frame 1-1.

[0021] like Figure 5 As shown, the nasal traction bracket 2 has two vertical positioning posts 2-1 in the middle. The middle part of the positioning post 2-1 has a slot 2-2. The elastic rope 5 is connected to the nasal traction bracket 2 through the slot 2-2 of the positioning post 2-1, which improves the quick connection of the elastic rope 5 and ensures the secure hanging of the elastic rope 5.
