The utility model has the advantages of simple structure, low cost and convenient use. Through the cooperation with the connecting rod and the positioning handle, the accurate positioning of the intramedullary nail is realized, and through the guide block, the Kirschner wire can accurately penetrate into the front hole of the intramedullary nail, which improves the accuracy of the puncture of the Kirschner wire. The number of Kirschner wire punctures is reduced, the patient's pain is relieved, and the positioning accuracy of the intramedullary nail is improved.

Description

Translucent femoral nail distal aiming frame

technical field

The utility model relates to the technical field of medical instruments, in particular to a light-permeable aiming frame for the distal end of a femoral intramedullary nail.

Background technique

At present, intramedullary nails are mostly used clinically to treat fractures, and this technique has little effect on the fracture ends. In the operation of installing intramedullary nails to treat fractures, the corresponding aiming device is required to drive the locking nail on the intramedullary nail. Vertical holes, side holes and/or oblique holes, otherwise it will affect the smooth progress of the operation and increase unnecessary pain to the patient.

Utility model content

The technical problem to be solved by the utility model is to provide a light-transmitting femoral intramedullary nail distal aiming device that can ensure that the locking nail is driven into the predetermined position of the intramedullary nail with high precision, and is convenient for debugging, economical, practical, safe and reliable. shelf.

In order to solve the above-mentioned problems, the technical solution adopted by the utility model is: the light-transmitting femoral intramedullary nail distal aiming frame includes a long strip-shaped frame body, and a plurality of through holes are arranged in the frame body along the length direction. The front end of the frame body is provided with a guide block, and a plurality of guide holes are arranged in the guide block. The arrangement direction of the guide holes is perpendicular to the length direction of the frame body, and the guide holes are symmetrical to the center line of the frame body in the length direction.

As a preferred solution, the number of the guide blocks is two, and the two guide blocks are arranged parallel to each other.

As a preferred solution, the shapes of the through holes include circular holes and elongated holes.

The beneficial effects of the utility model are: the above-mentioned translucent femoral intramedullary nail distal aiming frame has simple structure, low cost and convenient use. Through the cooperation with the connecting rod and the positioning handle, the accurate positioning of the intramedullary nail is realized, and the Kirschner wire can be accurately penetrated into the front hole of the intramedullary nail through the guide block, which improves the accuracy of the puncture of the Kirschner wire. The number of Kirschner wire punctures is reduced, the patient's pain is relieved, and the positioning accuracy of the intramedullary nail is improved.

Detailed ways

The light-permeable femoral intramedullary nail distal aiming frame described in the present utility model will be further described in detail through specific embodiments below.

As shown in Figure 1, the light-transmitting femoral intramedullary nail distal aiming frame includes a strip-shaped frame body 1, and a plurality of through holes 2 are arranged in the frame body 1 along the length direction, and the frame body 1 The front end is provided with a guide block 3, and a plurality of guide holes 4 are arranged in the guide block 3. The arrangement direction of the guide holes 4 is perpendicular to the length direction of the frame body 1, and the guide hole 4 is aligned with the center line of the length direction of the frame body 1. Relatively symmetrical.

As a preferred solution, in this embodiment, the number of the guide blocks 3 is two, and the two guide blocks 3 are arranged parallel to each other. To match with intramedullary nails of different specifications and sizes.

As a preferred solution, the shapes of the through holes 2 include circular holes and elongated holes. The function of the through hole 2 is mainly to select a suitable through hole 2 to connect with the connecting rod according to the specifications of the intramedullary nail.

The working principle of the utility model is: as shown in Figure 2, when in use, use the connecting screw 5 to pass through the through hole 2 to fix the connecting rod 6 on the frame body 1, and then connect the positioning handle 7 to the connecting rod 6 At this time, after the intramedullary nail 8 is installed on the positioning handle 7, the intramedullary nail 8 is parallel to the frame body 1 of the aiming frame, and the insertion direction of the intramedullary nail 8 is aimed at the insertion direction of the intramedullary nail 8 through the frame body 1, after the intramedullary nail 8 is inserted , use the Kirschner wire 9 to insert into the guide hole 4 in the middle of the guide block 3. Under normal circumstances, the Kirschner wire 9 will directly penetrate into the positioning hole at the front end of the intramedullary nail 8. If there is a deviation, the positioning can be performed through the image Judging, and then reselecting the position of the guide hole 4 where the Kirschner wire 9 is inserted, generally the Kirschner wire 9 can be accurately inserted into the positioning hole at the front end of the intramedullary nail 8 through the second positioning to realize positioning.

Above-mentioned embodiment only illustrates the principle of the present invention and its effect, and the embodiment of partial use, and is not intended to limit the present utility model; Under the premise of creating the concept of the utility model, some deformations and improvements can also be made, and these all belong to the protection scope of the utility model.
