Abstract
The utility model relates to a surgical medical instrument, in particular to a plate which is combined by using a locking hole and a pressing hole together. The medical instrument comprises a sheet. A group of communicating hole is arranged on the sheet. At least one communicating hole is composed of the overlapping part of the pressing hole and the locking hole. The pressing hole is strip without thread. The locking hole is ring with thread. The utility model has the advantages that the pressing hole and the locking hole are connected to each other together to make the doctor fix fractured bone by pressing or locking according to the need in the process of operation to supply convenience for operation. A rigid connection is form between a bone screw and a plate when being fixed by locking to relief the pressure between the plate and the periosteum greatly, can shorten convalescence after operation and relief pain of patient.
Description
Technical field
This utility model relates to a kind of surgical medical equipment, especially a kind of blade plate that lock hole is used in combination with the pressurization hole.
Background technology
It is fixing often to need to utilize blade plate and bone screw that fracture site is implemented in bone surgery, traditional forcing screw, can be by blade plate tightly being pressed to periosteum to form pressurization to the bone section, but shearing force had lower resistance, and this shearing force causes forcing screw generation relaxation and blade plate can reduce blood confession to bone to the compressing of periosteum, has prolonged recovery time; Lock screw has higher resistance to shearing force, under the effect of this resistance, make to guarantee stability on lock screw/bone-plate holes interface, but it can not pressurize to the knochenbruch face, makes knochenbruch be in the healing that released state is unfavorable for knochenbruch.Like this, in some clinical practice, the blade plate that uses non-locking screw to combine with lock screw will be ideal selection.Patent 20052001830.7 discloses a kind of blade plate with independent lock hole and pressurization hole, this patent is that the needs according to reality are provided with independently the pressurization hole and the lock hole of strip on bar shaped or T shape blade plate, but the screwed hole versatility on this blade plate is poor, and pressurization hole or lock hole are arranged on where just can only use this fixed form.
Summary of the invention
In order to overcome the deficiency of above-mentioned blade plate,, in a hole, can use lock screw or common forcing screw for the surgeon provides a kind of blade plate with bigger motility.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of blade plate, have sheet material, sheet material is provided with one group of through hole, and wherein serve as reasons pressurization hole and lock hole of at least one through hole partly overlaps and formed, the pressurization hole is that bar shaped does not have screw thread, and lock hole is circular threaded.
Further, the end of the counterbore in pressurization hole is provided with live end, and in order to reach the effect of pressurizeing preferably, the gradient of live end is 40 °.
Other lock hole is made up of arcuation counterbore and screwed hole.
Further, the profile of sheet material is bar shaped or approximate T type, and thickness is between 0.8mm ~ 7mm; Other through holes on the sheet material are independent lock hole, independent pressurization hole.
The beneficial effects of the utility model are: partly being overlapped by pressurization hole and lock hole on the blade plate of the present utility model can be according to the operation needs in the through hole of being formed, use lock screw or forcing screw separately, have the motility of height and better therapeutic effect, also can fix the bone section back reuse lock screw of pressurizeing in addition according to the pressure slope that adds that the end of operation needs by the counterbore in pressurization hole is provided with.
