Abstract
The utility model provides an auxiliary nail-placing guide plate for femoral neck fracture reduction, which comprises a guide plate body, wherein three positioning guide channels are arranged on the guide plate body, the length of each positioning guide channel is 2-3 mm, the guide plate body is a curved surface, the inner side surface of each guide plate body is an attaching surface, the shape of each guide plate body is matched with the outer side of a femoral tuberosity, and each positioning guide channel is positioned on the outer side surface of the guide plate body. Compared with the traditional femoral neck fracture reduction operation, the utility model has the advantages of simple operation, accurate fracture reduction, less X-ray perspective times in operation and small radiation quantity, can flexibly design drawings according to the types of the selected steel plates and screw instruments, simulate operation rules, print out an operation guide plate through 3D printing for use in operation, greatly shorten operation time, reduce the exposed wound surface of an operation part by using the guide plate, and reduce complications of the operation.
Description
Technical Field
The utility model belongs to the technical field of medical appliances, and particularly relates to an auxiliary nail-placing guide plate for femoral neck fracture reduction.
Background
The operation of resetting the fracture of the neck of femur needs to implant the steel sheet under the tuberosity outside the tuberosity of the femur, the broken trochanter of femur is reset and connected with the proximal end of femur through lag screw and steel sheet, the existing steel sheet is fixed and reset according to clinical experience of doctors, can lead to the unable accurate positioning of the position of putting into of steel sheet and screw like this, certain deviation appears, leads to the unsatisfactory reduction, and the healing rate is low, therefore, the development and development of a femoral neck fracture resetting auxiliary nail-setting guide plate, ensure the accuracy of resetting is very necessary.

Description of the embodiments
The utility model is further described below with reference to the accompanying drawings, without limiting the utility model in any way, and any alterations or substitutions based on the teachings of the utility model are intended to fall within the scope of the utility model.
As shown in the drawing, the utility model comprises a guide plate body, wherein three positioning guide channels 2 are arranged on the guide plate body, the length of each positioning guide channel 2 is 2-3 mm, the guide plate body is a curved surface, the inner side surface of each guide plate body is an attaching surface 4, the shape of each guide plate body is matched with the outer side of a femur tuberosity 1, and each positioning guide channel 2 is positioned on the outer side surface of the guide plate body.
The locating guide channel 2 and the guide plate body are arranged at an included angle.
The operation method of the utility model comprises the following steps:
the auxiliary nail-placing guide plate for femoral neck fracture reduction is designed according to the mounting hole of the proximal femur steel plate
In the method, the femoral trochanter and tuberosity fracture position is adjusted to reset under traction in operation, a guide plate is attached and fixed to the tuberosity outside the femoral tuberosity, three 2.5mm diameter Kirschner wires are inserted into the femoral trochanter along a guiding nail placing channel on the guide plate until the operation nail placing channel is established, after the relative positions of the trochanter and the tuberosity are fixed, the nail placing guide plate is withdrawn, mounting holes corresponding to a steel plate at the proximal end of the femur are respectively penetrated with Kirschner wires at corresponding positions, the Kirschner wires are sleeved in a central hole of a hollow lag screw, the steel plate is fixed at the femoral tuberosity along the channel established by the Kirschner wires, the rotor and the tuberosity of the fracture are connected together by the pressurizing connection of the screw, and finally, after the steel plate is completely fixed, the three Kirschner wires are taken out, and the wound is sutured.
While the present utility model has been described in detail with reference to the drawings, the scope of the utility model is not limited to the above embodiments, and various changes can be made by those skilled in the art without departing from the spirit of the utility model.
