Description

Radius distal ulna dorsal bone block restorer

Technical Field

The invention relates to the field of orthopedic treatment equipment, in particular to a radius distal ulna dorsal bone block restorer.

Background

Distal radius fractures are one of the most common fractures in the clinic, and cases of unstable fractures or failure of conservative treatment require surgical treatment. The palmar bone fracture plate technology is the most commonly used method at present, but the palmar bone fracture plate technology is difficult to reset and fix the ulnar dorsal bone block which is a key bone block, and the joint of a patient is painful and unstable due to poor resetting, even the disabled which cannot be treated is left.

The importance of the dorsal ulnar bone mass is represented by:

1. it not only forms the radial-wrist joint, but also forms the lower ulnar-radial joint;

2. it is located in the middle pillar, i.e. the main pillar for transmitting mechanics;

3. it provides an insertion point for the lower ulnar-radial-dorsal ligament, an important component of the triangular fibrocartilage complex (TFCC).

Therefore, in order to obtain good curative effect, good reduction and fixation are needed, the palm side bone fracture plate technology cannot meet the requirement, and the dorsal side incision reduction internal fixation is needed, so that the wound is expanded, and the economic burden of families and society of patients is greatly increased.

The base plate is characterized by further comprising an auxiliary plate, wherein the auxiliary plate is arranged on one side of the base plate, and a certain included angle is formed between the auxiliary plate and the surface of the base plate.

Further, still include soft silica gel pad, soft silica gel pad sets up on the backing plate.

Further, still include soft silica gel pad, soft silica gel pad sets up on the accessory plate.

Furthermore, the rear end of the first member is provided with a first arc-shaped strip, the rear end of the second member is provided with a second arc-shaped strip, and the first arc-shaped strip and the second arc-shaped strip are provided with positioning teeth matched with each other.

Detailed Description

The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

A distal radius ulnar dorsal bone block restorer, as shown in figures 1 to 4, comprises a first member 1, a second member 2, a backing plate 3 and a fixing head 4.

As shown in fig. 1 and 2, the rear end of the first member 1 is provided with a first handle 5, the rear end of the second member 2 is provided with a second handle 6, the second member 2 and the first member 1 are arranged in a scissor-like manner, and the first member 1 and the second member 2 are operated by the first handle 5 and the second handle 6. Here, the first member 1 and the second member 2 may be made of stainless steel, or may be made of PPSU, which is polyphenylene sulfone resin, is a novel thermoplastic engineering plastic, is resistant to repeated steam sterilization, can be reused, and has passed the relevant specifications of the U.S. medicine and food fields, and may replace stainless steel products.

Referring to fig. 3 in combination, the backing plate 3 is disposed at the front end of the first member 1, and a connecting frame as shown in fig. 4 may be used, the fixed head 4 is disposed at the front end of the second member 2, and the fixed head 4 and the backing plate 3 are disposed opposite to each other. When the first handle 5 and the second handle 6 are close, the first member 1 and the second member 2 rotate, and the fixed head 4 and the backing plate 3 are close.

When the fracture plate is used, the backing plate 3 is attached to the back side of a fracture, the bone fracture plate is placed on the palm side of the fracture, the fixing head 4 is pressed on the bone fracture plate, then the first handle 5 and the second handle 6 are forcefully extruded, and bone blocks on the back side can be clamped under the action of the bone fracture plate and the backing plate 3, so that restoration is completed. The fixed head 4 extrudes the bone fracture plate downwards, the bone fracture plate does not deviate under the action of the fixed head 4, so that a sharp corner is arranged at the front end of the fixed head 4, and when the fixed head 4 is contacted with the bone fracture plate, the sharp corner can be partially inserted into the bone fracture plate to play a role in positioning.

For better screens, designed accessory plate 7, accessory plate 7 sets up in one side of backing plate 3, and accessory plate 7 and the face of backing plate 3 are the setting of certain contained angle. The auxiliary plate 7 and the backing plate 3 can be integrally formed and designed into a whole, when the backing plate 3 is placed on the back side of the fracture, the auxiliary plate 7 can lean against the skin on one side of the radius, and the effect of quick positioning can also be achieved. In addition, the auxiliary plate 7 and the backing plate 3 are in direct contact with the skin, a soft silica gel pad 8 is designed, and the soft silica gel pad 8 is arranged on the backing plate 3 and the auxiliary plate 7 to play a role in preventing the skin from being crushed and preventing bone fragments from being cracked.

After the first handle 5 and the second handle 6 are squeezed, the positions of the first handle 5 and the second handle 6 need to be kept, the fracture part is bound, and when the first handle 5 and the second handle 6 are squeezed, the squeezing degree needs to be controlled, preferably, the rear end of the first component 1 is provided with a first arc-shaped strip 9, the rear end of the second component 2 is provided with a second arc-shaped strip 10, and the first arc-shaped strip 9 and the second arc-shaped strip 10 are provided with positioning teeth matched with each other.

The first arc-shaped strip 9 and the second arc-shaped strip 10 are mutually clamped by the positioning teeth, so that the extrusion degree is ensured, and the reverse resetting of the first handle 5 and the second handle 6 can also be avoided. Here, the positioning teeth are helical teeth, and since the first member 1 and the second member 2 have certain elasticity, the first member 1 and the second member 2 can be separated outwards in the non-rotating direction, which plays a role in adjusting the reset of the positioning teeth. The first arc-shaped strip 9 and the second arc-shaped strip 10 in the figures 1 and 2 have different sizes, and are convenient to operate.

It should be understood that the above embodiments are only for illustrating the technical solutions of the present invention, and not for limiting the same, and it is obvious for those skilled in the art that the technical solutions described in the above embodiments can be modified or some technical features can be replaced equivalently as long as no structural conflict exists; and all such modifications and alterations are intended to fall within the scope of the appended claims.
