Detailed Description
The following describes specific embodiments of the present utility model in detail with reference to the drawings.
According to an embodiment of the present utility model, an X-shaped locking bone plate is provided. Wherein fig. 1-3 show one specific embodiment.
Referring to fig. 1 to 3, the X-shaped locking bone fracture plate is in an X shape, and comprises a main plate 1 and four wing plates 2 arranged on the main plate 1, wherein the wing plates 2 are symmetrically arranged relative to the main plate 1, and the main plate 1 and the wing plates 2 are both formed into curved surfaces so as to be attached to a bone surface; wherein, each wing plate 2 is provided with a locking hole 3 for inserting a locking screw, and the locking holes 3 are arranged to allow the maximum angulation of the locking screw to be 15 degrees in all directions away from the axis; the main board 1 is also provided with a pressurizing hole 4 and a Kerr pin hole 5 at intervals. Wherein, the pressurizing hole 4 is designed to provide pressurizing and locking functions; the k-wire hole 5 design provides temporary fixation.
The working process of the X-shaped locking bone fracture plate is as follows: the X-shaped locking bone plate can be selected if the specific position of the fracture of the patient is determined, and if the patient is a metacarpal bone, a phalangeal bone or a metatarsal bone fracture. The fracture part is cut and reset, after the completion of the reset, the X-shaped locking bone fracture plate is placed at the fracture reset position by forceps, and a Kirschner wire or a reset forceps is used for temporary fixation at the Kirschner wire hole 5 when necessary. The Kirschner wire holes 5 can effectively fix the steel plate temporarily at this time, and coarse positioning is realized.
Thereafter, starting from the compression hole 4 of the bone plate, drilling with a universal drill bushing and drill bit, then measuring the depth of the drilled hole, selecting an appropriate cortical screw or locking screw according to the specific patient's condition, if the locking screw and cortical screw are planned to be used simultaneously, inserting the cortical screw to pull the plate to the bone side; if the locking screw is inserted first, it is necessary to ensure that the steel plate is firmly fixed to the bone to avoid the steel plate rotating when the locking screw is locked.
There are two modes of operation of drilling holes when using locking screws: one is to align and insert the universal LCP pilot drill tip into the locking hole 3 of the bone plate, drill to the desired depth at the desired angle using a drill bit, wherein a funnel-shaped drill sleeve allows the drill bit to drill at an angle of 15 ° maximum to the axis of the surrounding locking hole 3; another way is to use a free-hand type universal LCP drill guide, insert it completely into the universal LCP hole, drill the locking hole 3 at the desired angle, and measure the correct locking screw length using a corresponding depth finder.
A locking screw of a preset angle is then implanted starting from the leftmost universal locking hole 3. In turn, holes are drilled in the universal locking holes 3 at appropriate locations, and the locking screws are implanted using the starter.
Finally, the screw is locked by using a torque limiting spanner, the implantation of the bone plate is completed, and then the skin is sutured.
Through the technical scheme, the locking hole 3 allows the maximum angulation of the locking screw to be 15 degrees in all directions away from the axis, accords with an anatomical structure, and solves the problem that the bone fracture plate cannot be used due to the fact that the preset angle of the locking hole 3 is not in accordance with the requirement in the prior art. The curved surface design of the main board 1 and the wing plate 2 enables the bone fracture plate to be well attached to the bone surface, and postoperative pain is reduced. The screw suitable for the locking hole 3 is a universal locking screw, a standard locking screw, a cortical screw and other various screws, has better universality and applicability, and can be properly exchanged under special conditions, so that the screw is convenient for clinical use in the later stage.
When the X-shaped locking bone fracture plate is applied to fractured bones, different bone surfaces can be well attached, the locking position can be flexibly adjusted according to the fractured bone condition of a patient, and a stable, reliable and safe environment is provided for the fractured bones, so that the X-shaped locking bone fracture plate is beneficial to postoperative recovery.
In an exemplary embodiment provided in the present disclosure, the main plate 1 is square, and the pressurizing hole 4 is formed as a kidney-shaped hole. The structure design can enable a doctor to finely adjust the position of the main board 1 during operation, has certain fault tolerance and is more convenient to use. The pressurizing hole 4 is located at the center of the main plate 1, and is beneficial to uniformly transfer pressure to other positions of the main plate 1.
In the present disclosure, two k-pin holes 5 are configured, and the two k-pin holes 5 are respectively disposed on two sides of the pressurizing hole 4 along the length direction of the main board 1, so that two-point positioning is realized through connection of the k-pin and broken bone, stability and reliability of positioning of the bone fracture plate are improved, and a good foundation is provided for subsequent operations.
In the present disclosure, the edge profile of the wing plate 2 is curved so that the design does not create sharp points or weaknesses, which is beneficial in providing a reliable supporting environment for the fractured bone.
In one possible design, the edges of the main plate 1 and the wing plate 2 are provided with fillets or bevels, so that the irritation to bone tissues and muscle tissues can be reduced, and the discomfort at the wound can be reduced.
Alternatively, the main board 1 and the wing board 2 are integrally formed, which is beneficial to manufacturing and forming and reduces shape and position errors; the width of the wing plate 2 gradually becomes smaller along the direction deviating from the main plate 1, so that the size of the wing plate 2 can be changed slowly, stress concentration is prevented, and the bending strength of the wing plate 2 is ensured under the condition of reducing the area of the wing plate.
In the present disclosure, the contour line between the two wing plates 2 is C-shaped along the width direction of the main plate 1. This allows smooth transfer of pressure between the flanges 2 and prevents deformation or cracking due to stress concentration.
The preferred embodiments of the present utility model have been described in detail above with reference to the accompanying drawings, but the present utility model is not limited to the specific details of the above embodiments, and various simple modifications can be made to the technical solution of the present utility model within the scope of the technical concept of the present utility model, and all the simple modifications belong to the protection scope of the present utility model.
