Abstract
The utility model belongs to the technical field of medical equipment, and provides a pressurizing bone connecting plate aiming to solve technical problems existing in a pressurizing bone connecting plate currently used in the operation process. The pressurizing bone connecting plate comprises a strip-shaped plate, and a plurality of threaded holes penetrating through the plate are formed in the surface of the strip-shaped plate. The pressurizing bone connecting plate is characterized in that a T-shaped clamping groove is formed in the back side of the plate, a plurality of protrusions capable of freely sliding are arranged in the clamping groove, through holes are formed in the protrusion bodies, when one protrusion slides to the lower portion of one threaded hole, the corresponding threaded hole will be communicated with a through hole in the protrusion. Due to the adoption of the pressurizing bone connecting plate, operation strength of doctors is greatly reduced, pains of patients are reduced, the contact area of the bone connecting plate and bone surfaces is further reduced, blood capillaries of periosteums are further less affected, and cortical bone healing can be fast promoted.
Description
Technical field
This utility model belongs to technical field of medical instruments, is specifically related to a kind of pressurized bone plate used while fracturing that is used for the treatment of.
Background technology
Pressurized bone plate is a kind of blade plate that can play the pressurization fixation.The Limited contact Dynamic Compression Plate is further developing of Dynamic Compression Plate.This blade plate adopts rustless steel or pure titanium manufacture usually, and its structure is on strip material, to offer several screw holes, is provided with several projections in the bottom of strip material, and projection is provided with the through hole connected with screw hole.The area (blade plate trace) that contacts with bone of blade plate reduces greatly like this, and the impact that the capillary network of periosteum is subject to is very little, therefore can promote the cortex symphysis, can also avoid the osteoporosis under blade plate.But in use find, projection quantity and position on this blade plate are fixed, when carrying out operation technique, the projection position of blade plate bottom surface has exactly affected coincideing of fracture, the position that needs constantly to adjust blade plate is fixed, this has not only increased the length of wound, has increased simultaneously doctor's labor intensity and patient's misery.
Summary of the invention
For the pressurized bone plate that solves current use exists in operation process technical problem, this utility model provides a kind of can adjust pressurization projection position, the pressurized bone plate that facilitates the doctor to operate flexibly.
For realizing above-mentioned technical purpose, the technical solution adopted in the utility model is: a kind of pressurized bone plate, comprise a strip boards, on the surface of strip boards, offer the screw hole that several run through sheet material, it is characterized in that: the back side of described sheet material is provided with the convex shape draw-in groove, in draw-in groove, is provided with the projection that several can be free to slide, and the projection body is provided with through hole, when projection slid into a certain screw hole bottom, the screw hole that it is corresponding and the through hole on projection connected.
As can be known by foregoing description, this pressurized bone plate can be adjusted the quantity of projection and position flexibly to adapt to the actual needs in operation technique.Adopt this pressurized bone plate greatly to alleviate doctor's operation strength, reduced patient's misery, further reduced simultaneously the contact area of blade plate and surface of bone, make periosteum blood capillary influencedly further alleviate, can promote fast the cortex symphysis.
The accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is the structural representation of projection in this pressurized bone plate.
In figure, 1, sheet material, 2, screw hole, 3, draw-in groove, 4, projection, 5, through hole, 6, the projection seat, 7, tapered bosses.
The specific embodiment
Below in conjunction with drawings and Examples, this utility model is described further.
As shown in Figure 1, a kind of pressurized bone plate, comprise a strip boards 1, on the surface of strip boards, offers several screw holes that runs through sheet material 2.
As shown in Figure 1, the back side of this sheet material 1 is provided with convex shape draw-in groove 3, in draw-in groove 3, is provided with several projections that can be free to slide 4, and the projection body is provided with through hole 5.
As shown in Figure 2, projection 4 comprises the projection seat 6 that coordinates slip with draw-in groove 3, and projection seat 6 is a platysome, and a cone boss 7 is set on projection seat 6, and through hole 5 connects downwards to the bottom of projection seat 6 from the top of cone boss 7.
As can be known by foregoing description, during use, according to the practical situation of operation, select the quantity of projection 4, then slide protrusion 4 is to correct position, when projection slides into a certain screw hole 2 bottom, its corresponding screw hole 2 connects with the through hole 5 on projection, now adopts screw that sheet material 1, projection 4 and bone are fixed.By use this pressurized bone plate can reduce the quantity of projection 4 as far as possible, the minimizing of projection 4 quantity means further reducing of blade plate and surface of bone contact area, thereby reaches the impact reduced the periosteum blood capillary, the effect that promotes the cortical bone healing.
Claims (1)
