Structure of external fixing bracket

The present invention relates to a stent structure, and more particularly to a structure for fixing a stent other than an external fixation fracture.

The structure of the human body is very complicated, the division of labor is also quite fine, and the body can make a variety of postures and movements, which are roughly achieved by the cooperation of bones, muscles and various joints. The main structure of the human body can be divided into limbs and trunks. For the movable joints, in the upper limbs, there are shoulder joints, elbow joints, wrist joints and finger joints. In the lower limbs, there are hip joints, knee joints and ankle joints.

What is a fracture? The continuity of the bone is interrupted, not only the simple bone fracture, but also all the soft tissues and bones in the injured area, which is the definition of the fracture. Generally, the fracture refers to the damage of the hard bone. The classification of the fracture is determined according to the cause and condition of the injury; for example, a traumatic fracture caused by trauma, a spontaneous fracture caused by the disease or a pathologic fracture. If a broken bone passes through the skin and is exposed to the outside world, this condition is called a compound fracture. This type of fracture is caused by external harmful microorganisms that are easily invaded by damaged skin, resulting in a higher risk. If the fracture area is still intact and protected by intact skin, it is called simple fracture.

There are many different classifications in traumatic fractures, according to which the fracture can be divided into a close fracture and an open fracture, and the difference between the two is whether it causes skin damage and rupture. According to the direction of the fracture line can be divided into: 1. side bend fracture; 2. rupture fracture; 3. comminuted fracture; 4. transverse fracture; 5. oblique fracture; 6. spiral fracture.

In general, the method of fracture fixation is more commonly used for plaster fixation. When plaster is fixed, the plaster belt should be immersed in water to soften it. Then the plaster is carefully shaped to conform to the contour of the limb and maintain the limb in the reposition position without generating Improper torque, so until the plaster hardens. However, the use of gypsum has many disadvantages, such as the time required to wait for the plaster to harden, and the blood of the injured part to be circulated. Therefore, the conventional external fixation is replaced by an external fixation stent.

The external fixation stent is used to drill the needles or nails at both ends of the fracture, and then the needle that penetrates the fracture outside the skin is fixed on the external fixation frame. This method is not an internal fixation, nor is it an external fixation, but it has the effect that it cannot be achieved by internal fixation and external fixation in the past.

1. Role: (1) can maintain a good alignment of the fracture end; (2) can retract the ends of the fracture to extend the limb; (3) can use compression technology to promote fracture healing; (4) can correct early angular deformity and rotational deformity.

2. Types of commonly used external fixators are as follows: Single-arm external fixator: 4 through-the-needle needles, the outer end of the bone needle is fixed to one side, the steel needle penetrates one side of the skin, and is fixed by cortical bone. Parallel arrangement, external fixator with direction adjustment and fixation (Bastian frame); semi-ring type external fixator: multi-steel needle breaks through one side of the skin, needles are inserted in any direction, and the direction adjustment half ring holder (summer and peach type) is fixed; Ring-type external fixator: a variety of planes, two steel needles cross through the bone, through the bilateral skin, the outer fixed bracket ring fixed (ilizarov) type.

3. Advantages of external fixing bracket:

(1) It can maintain the alignment and the trauma is small.

(2) It can not only prolong the traction of the bone, but also pressurize the fracture end and promote the healing of the bone.

(3) In open fractures, the wound can be treated without affecting the fracture brake.

(4) It is possible to correct early angulation and rotational deformities.

4. Shortcomings:

(1) Pinhole infection is more common, especially for needles with thick needles.

(2) The steel needle and the steel needle fixing clip and the connecting rod are easy to loose, which affects the effect.

(3) The structure of the fixing frame is complicated, and the loading and unloading is inconvenient.

(4) Extracorporeal devices can affect some of the patient's daily activities.

The main purpose of this creation is to provide a structure for an external fixing bracket. Through a bracket and a plurality of fixing members, a bracket is used for external fixation to have a fixed effect, and the operation is avoided by avoiding the wound, thereby achieving the possibility of not affecting wound healing and reducing wound infection.

A secondary object of the present invention is to provide a structure for an external fixation bracket, and further comprising at least one support member disposed between the support member and the skin to enhance the supporting force of the bracket.

In order to achieve the above-mentioned various purposes and effects, the author of this work reveals a structure of an external fixation stent. This creation is based on the design of a fixed stent as an external fixation frame, and combined with minimally invasive surgery, for fracture patients, After the surface wound is treated again, the bone fixation is performed to reduce the burden on the patient to undergo surgery, in order to restore normal function in the shortest time.
