Description

Guide type correction bone screw Technical Field The utility model relates to the technical field of guide-type correction bone screws, in particular to a guide-type correction bone screw. Background Bone setting is divided into bone setting and medicine taking, wherein bone setting is the first step, and the key of treatment is that medicine taking promotes rapid growth of poroma, so that broken bones heal rapidly, and complete recovery is achieved. Setting bones, namely, the process of resetting the fracture part, correcting the misplaced part caused by the action of external force by an operation method, and fixing the part by an internal fixing method or an external fixing method (according to the position or the injury situation of a patient) so as to avoid the re-displacement. Bone screws are non-active surgical implants for bone engagement, which are commonly used to fix bone fragments directly or in combination with other internal implants (such as bone plates or intramedullary nails, etc.). When the bone of a human body is fractured, the bone fracture effect of the bone fracture screw main body on the bone of the human body is affected due to the fact that the bone fracture plate or the bone fracture of the human body is possibly caused in the using process of the bone fracture screw. To overcome these disadvantages, the present utility model provides a guided corrective bone screw. Disclosure of utility model The utility model aims to solve the defects in the prior art and provides a guide type correction bone screw. In order to achieve the purpose, the guide type correction bone screw comprises arc-shaped protection plates which are symmetrically arranged, wherein a first guide plate and a second guide plate are fixedly connected to the middle positions of the front side and the rear side of each arc-shaped protection plate respectively, one end of each arc-shaped protection plate is provided with a groove, and the other end of each arc-shaped protection plate is fixedly connected with an inner threaded ring. Further, two first inserted bars are fixedly connected with one end of the first guide plate. Further, two first jacks are formed in one end of the second guide plate, and the first inserting rods are inserted and connected with the corresponding first jacks. Further, the arc protection plate is fixedly connected with two second inserted bars at the position of one end of the groove. Further, two second jacks are formed in the position, located at one end of the inner threaded ring, of the arc-shaped protection plate, and the second inserting rods are inserted and connected with the corresponding second jacks. Further, the locking screws are connected in the inner threaded rings in a threaded mode. Further, arc guard plate, first guide board, second guide board, internal thread ring are integrative die casting structure, and the material is titanium alloy material. The utility model has the beneficial effects that: When the guide type correction bone screw is used, the two arc protection plates are sleeved on two sides of a bone and connected end to end, the arranged internal thread rings are aligned with the grooves, the arranged second inserted link is inserted and connected with the corresponding second insertion hole, then the second inserted link is in threaded connection with the internal thread rings through the locking screw, the arc protection plates are connected with the bone through the locking screw, so that the arc protection plates can be fixed with the bone, the number of the arc protection plates is selected according to the required length, the arc protection plates on the front side and the rear side can be connected through the first inserted link and the first insertion hole on the first guide plate and the second guide plate, and the guide and reinforcement effects can be achieved through the first guide plate and the second guide plate.
