Description
Technical field
The utility model relates to the field of medical instrument technology more particularly to a kind of distal radial palmar hook locking compress to connect
Bone plate.
Background technique
Fracture of distal radius shows a series of special fixation problems, is distinct from the fracture at other most of positions.
Distal bone folded block is in periarticular, and usual very little.The compact arranged tendon in proximal end and stndon sheath hinder big and thick steel plate
Use.Distal bone folded block is too thin and enough screw thread holding powers can not be provided for bone screws.Bone is screwed on distal bone folded block
Screw is likely to result in the iatrogenic crushing of bone block.In view of the above problems, traditional pegboard systems fixing means can not solve
State problem.In clinic, need to treat the fracture of distal radial palmar using the bone plate of distal radial palmar, although at present
Clinically have the bone plate for the treatment of distal radial palmar, but different degrees of destruction can be caused to tendon in far-end, such as
Present clinically common Distal-radius palmar-locking bone fracture plate is writing board shape, without the design of similar sharp hook, in fixing lock
It wants released part tendon to be just capable of fixing when fixed board, influences the recovery of postoperative patient.
Utility model content
The distal radial palmar that the purpose of the utility model is to provide a kind of structures is simple, locking effect is good, stickiness is good
Hook locked pressurized bone plate.
The utility model is achieved by the following technical solution: a kind of distal radial palmar hook locking compress synthetism
Plate, including a plate, the plate includes integrally formed mounting portion and hook part, if the mounting portion is evenly equipped with along center line
Dry locking screw thread hole, the mounting portion offer a waist type long slot hole far from one end of hook part, and the mounting portion includes level
Section and the bending section being folded upward at, hook part include the first hook part and the second hook part, the first hook part and the second hook part
Between have a U-shaped opening groove, first hook part or the second hook part include integrally formed bending section and extended segment, institute
It states bending section to connect with mounting portion, the extended segment extends downwardly, and has certain length.
In order to guarantee fixed fastness, the extended segment of first hook part and the second hook part is to close to mounting portion
One end tilts.
In the utility model another preferred embodiment, in order to improve the validity of fitting, first hook part and
Gather respectively into the center line of mounting portion the extended segment of two hook parts.
Preferably, uniformly distributed on the mounting portion, there are three locking screw thread holes.
The beneficial effects of the utility model are: the distal radial palmar hook locked pressurized bone plate passes through special designing
The mutual cooperation of mounting portion and hook part is preferable with the stickiness of distal radial palmar, it can be achieved that locking and pressurization function, fixed
It is solid and reliable, allow early ambulant, based on adjacent ipsilateral cortex bone fixation, damage is small, and the design of undercut mark is reduced to soft tissue
Excitation.

Specific embodiment
The preferred embodiment of the utility model is described in detail with reference to the accompanying drawing, so that the advantages of the utility model
It can be easier to be understood by those skilled in the art with feature, to make apparent specific boundary to the protection scope of the utility model
It is fixed.Direction term that the utility model is previously mentioned, such as "upper", "lower", "front", "rear", "left", "right", "top", "bottom" etc.,
It is only the direction with reference to annexed drawings.Therefore, the direction term used be to illustrate and understand the utility model, rather than to
Limit the utility model.
As shown in Figure 1-3, a kind of distal radial palmar hook locked pressurized bone plate, including a plate 8, the plate 8
Including integrally formed mounting portion and hook part, uniformly there are three locking screw thread hole 6, the installations along center line for the mounting portion
Portion offers a waist type long slot hole 7 far from one end of hook part, and mounting portion includes horizontal segment 9 and the bending section being folded upward at 10,
Hook part includes the first hook part and the second hook part, has a U-shaped opening groove 5 between the first hook part and the second hook part,
First hook part includes integrally formed bending section 3 and extended segment 1, and second hook part includes integrally formed bending
Section 4 and extended segment 2, the bending section 3, bending section 4 are connect with bending section 10, and two extended segments extend downwardly, and to close to bending
One end (being illustrated as to the right) of section 10 tilts, and two extended segments are gathered into the center line of mounting portion respectively.
The distal radial palmar hook locked pressurized bone plate is an integral structure, and main body is plate 8, is divided on plate 8
Multiple locking screw thread holes 6 are furnished with, for being cooperated with lock screw, and meanwhile the Kong Weiyi waist type long slot hole 7 of tail portion second, hole
An interior common bulb bone screw of putting is, it can be achieved that fracture with compressive.The distal radial palmar hook locked pressurized bone plate head
It is divided into two flex areas from hook part toward main bent part transition for two hook parts, there is a U-shaped opening groove 5 among two hooks,
The destruction to tendon can be reduced.
This patent is opened one among two hooks and is opened especially in two hooks of the Position Design of distal radial palmar distalmost end
Slot, on the one hand, hook can inject inside distal radial palmar bone, by subsequent pressurization hole, cooperate special tool to bone
Trisection is pressurizeed, while hook injects the rotation that distal radial palmar fracture site can be also prevented in bone.On the other hand, it opens
The slot put can accommodate tendon, reduce the destruction to tendon.
Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed,
But it cannot be understood as the limitations to utility model patent range.It should be pointed out that for the common skill of this field
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The protection scope of the utility model.
