Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of physical therapy and health care equipment, and particularly relates to a fixator for treating maxillofacial venous malformations. Background Art
[0002] The treatment of maxillofacial venous malformations mainly adopts embolization, drug injection and other methods. When injecting drugs, in order to make the drugs stay in the deformed area, the ring will press the circumference.
[0003] Application No. 2006200099450 discloses a fixator for treating maxillofacial venous malformations. The device comprises two circular rings, each connected by a band-shaped elastic clip at the top and an elastic band at the bottom. The outer sides of the two rings are each provided with a fixing band, and the ends of the fixing bands are each provided with a parent-child adhesive buckle. The device has a simple structural design and is easy to manufacture. During use, the elastic clip at the top of the two rings is placed on the head, and the elastic band at the bottom of the two rings is placed on the mandible. The rings are then pressed against the area of the maxillofacial venous malformation. The drug is then injected through the ring holes. After the injection, the rings are secured with the fixing bands on the outer sides of the two rings, and the pressure is maintained for 10 to 12 hours.
[0004] The above method can achieve good results, but there are many inconveniences. Maxillofacial venous malformations are not symmetrical and usually appear on one side. Double rings will cause skin discomfort on the other side. Patients vary greatly in age and body shape, and elastic clips are not suitable for more patients. The existing maxillofacial venous malformation fixators are inconvenient to use. Summary of the Invention
[0005] The purpose of the utility model is to solve the problem that the existing fixation device for maxillofacial venous malformation is inconvenient to use, and to provide a fixation device for treating maxillofacial venous malformation to solve the deficiencies of the existing technology.
[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0007] A fixator for treating maxillofacial venous malformations comprises brackets; the brackets are cross-distributed and provided with a rotating shaft; the brackets below the rotating shaft are arc-shaped, with a pressure ring at one end and a cotton pad at the other end; a diamond-shaped adjustment bracket is provided between the brackets above the rotating shaft; the adjustment bracket is rotatably connected to the brackets via a pin; nuts rotatably connected via a pin are provided between the other two intersection points of the adjustment brackets, the two nuts have opposite threads and are provided with an adjustment screw.
[0008] Furthermore, an arc-shaped ring is provided on the back of the pressure ring, the bracket is connected to the middle of the arc-shaped ring, and the connecting part is opposite to the center of the pressure ring.
[0009] Furthermore, the cotton pad and the bracket are movably connected.
[0010] Furthermore, an elastic joint is provided between the bracket and the cotton pad and / or between the bracket and the pressure ring.
[0011] Furthermore, the bracket and the adjustment frame are made of magnesium alloy or aluminum alloy.
[0012] The utility model clamps the face of a human body by opening and closing the bracket, has a wide range of applications, and has more appropriate strength, thus effectively solving the shortcomings of the prior art. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] Figure 1 This is a schematic diagram of the structure of the utility model;
[0014] Figure 2 This is a schematic diagram of the compression ring connection structure of the utility model. DETAILED DESCRIPTION
[0015] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. In the description of the present invention, it is obvious that the embodiments described below are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0016] Example 1: According to Figure 1-2 A fixator for treating maxillofacial venous malformations comprises a bracket 2; the brackets are cross-distributed and provided with a rotating shaft 3; the bracket below the rotating shaft is arc-shaped, with a pressure ring 5 at one end and a cotton pad 4 at the other end; a diamond-shaped adjustment bracket 1 is provided between the brackets above the rotating shaft; the adjustment bracket is rotatably connected to the bracket through a pin 9; a nut 8 rotatably connected through a pin is provided between the other two intersection points of the adjustment bracket, the two nuts adopt reverse threads and are provided with an adjusting screw 7.
[0017] When in use, place the pressure ring 5 on the deformed part, turn the adjusting screw 7, adjust the frame 1 to support both sides, and tighten the bottom of the bracket. When the other end of the bracket is close to the head or face, place a suitable cotton pad 4 and continue to turn the adjusting screw 7 to keep it clamped and comfortable.
[0018] like Figure 2 The back of the pressure ring is provided with an arc ring 6, and the bracket is connected to the middle of the arc ring, and the connection part is opposite to the center of the pressure ring. There are 2-4 fulcrums between the arc ring 6 and the pressure ring, which are evenly distributed. The force applied by the bracket can be more evenly transmitted to the pressure ring, thereby preventing bias.
[0019] The cotton pad is movably connected to the bracket. Since the position of the cotton pad on one side of the bracket is different for the face or the head, the cotton pads are arranged in different sizes and hardness and are placed at the right time.
[0020] An elastic joint 10 is provided between the bracket and the cotton pad or between the bracket and the pressure ring. The elastic joint 10 adopts a box body with a built-in spring. During use, it contracts according to changes such as facial expressions to prevent it from falling.
[0021] The bracket and the adjustment frame are made of magnesium alloy or aluminum alloy. The weight of the entire device is controlled within 80g to reduce the pressure caused by weight.
[0022] The utility model clamps the face of a human body by opening and closing the bracket, has a wide range of applications, and has more appropriate strength, thus effectively solving the shortcomings of the prior art.
