Abstract
The utility model belongs to medical equipment, in particular to a locking and pressing bone fracture plate. The locking and pressing bone fracture plate comprises a bone fracture plate body, and is characterized in that the bone fracture plate is arc-shaped; a plurality of through holes are formed on the bone fracture plate body, wherein at least one through hole is a combination hole formed by partially overlapping a pressing hole groove and a locking hole; and at least one of the pressing hole groove and the locking hole is provided with a check ring device which stops a bone fracture bolt arranged into the bone fracture plate. In the utility model, a locking bolt or a pressing bolt can be used independently according to the operational requirements, and high flexibility and better therapy effects can be achieved; moreover, the bone fracture surface can be pressed by a pressing slope arranged at the end part of the countersunk hole of the pressing hole groove and then fixed by the locking bolt according to the requirements in the operation. The locking and pressing bone fracture plate has reasonability in structure, simplicity in manufacture, flexibility in use, and ideal effects.
Description
Technical field
This utility model belongs to medical mechanical domain, specifically is a kind of locked pressurized bone plate.
Background technology
At present, the steel plate screw osteopathy is the important means of fractures.The therapeutic modality of one of them is that blade plate and ball screw are used, and its operation principle is: producing frictional force by pressurization back between steel plate, screw and the surface of bone provides fracture stabilization to fix, through such fixed form; Can keep the relative stability of fracture; Make the patient can be convenient to use injured limbs, and reduce the pain when bearing weight, but along with the application of blade plate; In the fracture loses stability, cause operative failure; Another kind is that the threaded screw fit of blade plate and head of screw is used; Its operation principle is: blade plate cooperates with screw is stable, and screw is connected with the sclerite Wanding, thereby the held stationary of sclerite is provided; This fixed form can protect the blood flow of fracture can further not reduce; Promote the healing of fracture, but effective pressurization effect can't be provided, in clinical use, significant limitation is arranged.Like this, in some clinical practice, the blade plate that uses non-locking screw to combine with lock screw will be ideal selection.In the synthetism operation, the screw of packing into is sliding easily moving back after a period of time, influences therapeutic effect in addition.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiency of above-mentioned blade plate, for the surgeon provides a kind of more flexible, safe and reliable locked pressurized bone plate that can use two kinds of osteopathies simultaneously.
The technical scheme that this utility model adopted is:
A kind of locked pressurized bone plate; Comprise blade plate; It is characterized in that: blade plate is an arc, and several through holes are set on blade plate, and wherein at least one through hole is the combined hole that pressurization hole slot and lock hole partly overlap and form; At least one is provided with the back-up ring device pressurization hole slot and lock hole, and the back-up ring device plays the stopping effect to the bone screw of the blade plate of packing into.
This utility model pressurization hole slot does not have screw thread, and the counterbore end of pressurization hole slot is provided with and adds pressure slope, thereby reaches the effect of pressurizeing preferably; This utility model lock hole is band taper thread hole, and by forming in arcuation counterbore and taper thread hole, band taper thread hole tapering is 0 °～30 °.
Pressurization hole slot on this utility model locked pressurized bone plate and lock hole partly overlap the combined hole of being formed can be according to the operation needs; Use lock screw or forcing screw separately; Have high degree of flexibility and better therapeutic effect, in addition can also be as required the counterbore end through the pressurization hole slot is provided with in operation process adds pressure slope the bone section back reuse lock screw of pressurizeing is fixed.Simultaneously can lock pressurization, it is loosening to prevent that blade plate from taking place in fracture healing process, increases the reliability of fracture fixation, makes the bone fracture internal fixing device tool more solid and reliable, the accelerating bone healing time, thus guarantee to perform the operation successfully, reduce the patient suffering.The back-up ring device can make the bone screw of the blade plate of packing into play the effect of stopping.
This utility model is rational in infrastructure, makes simply, uses flexibly, and is satisfactory for result.

Fig. 1 is the example structure sketch map of this utility model.
Fig. 2 is the A-A profile of Fig. 1.
The specific embodiment
Like Fig. 1, the embodiment shown in 2, a kind of locked pressurized bone plate comprises blade plate 1; It is characterized in that: blade plate 1 is arc, and several through holes are set on blade plate 1, and wherein at least one through hole is the combined hole that pressurization hole slot 2 and lock hole 3 parts overlap and form; At least one is provided with back-up ring device 7 pressurization hole slot 2 and lock hole 3; Pressurization hole slot 2 is circle or bar shaped, no screw thread, and lock hole 3 is made up of arcuation counterbore 6 and taper thread hole 5; Taper thread hole 5 taperings are 0 °～30 °, are provided with in the end of counterbore of pressurization hole slot 2 to add pressure slope 4.
This utility model adds pressure slope 4 and adds pressure slope for sphere.
Claims (4)
