Anatomic calcaneus locking bone plate

Abstract

The invention discloses an anatomic calcaneus locking bone plate which comprises an upper locking pressurization section and a lower locking pressurization section. The upper locking pressurization section and the lower locking pressurization section are connected with each other by a connecting locking pressurization section to be integrally distributed to form an approximate U shape, and a forking locking pressurization section which is upwardly arranged further integrally extends at the outer end of the lower locking pressurization section; the upper locking pressurization section, the lower locking pressurization section, the connecting locking pressurization section and the forking locking pressurization section are respectively arc-shaped along the respective length directions of the upper locking pressurization section, the lower locking pressurization section, the connecting locking pressurization section and the forking locking pressurization section and can cling to the surface of the calcaneus of a patient, pressurization tension holes and locking holes are further formed in the upper locking pressurization section, the lower locking pressurization section, the connecting locking pressurization section and the forking locking pressurization section along the respective length directions of the upper locking pressurization section, the lower locking pressurization section, the connecting locking pressurization section and the forking locking pressurization section at intervals, the walls of the pressurization tension holes are smooth, and internal threads are arranged in the locking holes; a supporting portion which can support the calcaneus of the patient from bottom to top further integrally extends at the bottom of the lower locking pressurization section. The anatomic calcaneus locking bone plate has the advantages that preliminary shaping which conforms to the anatomic structure of the calcaneus of the body of the patient is performed on the anatomic calcaneus locking bone plate, operation steps are saved, and the anatomic calcaneus locking bone plate is good in calcaneus locking effect and is high in stability during usage.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an anatomical locking calcaneal bone plate. Background technique [0002] Human calcaneus fracture is a common foot injury, and the common ones are comminuted fracture and subtalar articular surface collapse. Since the human calcaneus is cancellous bone and irregular bone, and the multiple articular surfaces of the calcaneus are uneven, and the doctor follows the principle of non-invasive fracture reduction surgery, avoiding too much subcutaneous peeling as much as possible. The structure of the currently used calcaneous bone plate is as follows: it includes the main body of the calcaneous bone plate, which is composed of several pressurized sections arranged in one piece, all the pressurized sections are located on the same plane and are divided into chicken feet. Fork-type setting, a number of tension and pressure holes with smooth hole walls are opened on each pressure sect...

Problems solved by technology

The disadvantage of this calcaneus bone plate is: on the one hand, when performing fracture reduction surgery, since this calcaneus bone plate is all smooth tension and pressure holes, the doctor can only press and fix the calcaneus. The bone plate is fixed to the calcaneus, that is, the calcaneus bone plate is fixed to the calcaneus through the tension nail matched with the tension pressure hole, and the tension nail is to make the calcaneus bone plate bear the force by applying pressure to the calcaneus bone plate Fitting with the bone surface of the calcaneus, it is very easy to produce a sense of pressure on the calcaneus, which is not conducive to the recovery of the affected area, and it is also easy to cause people to feel a sense of pressure on the affected area after surgery. The stability of the fixed calcaneal bone plate is poor, and it is easy to fall off; on the other hand, all the pressurized sections that make up the body of the calcaneal bone plate are on the same plane, and the doctor needs to perform subcutaneous peeling to make the calcaneal bone plate fit the heel. Bone surface, resulting in unnecessary secondary injury
