Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a honeycomb proximal femoral opening cone. Background Technology

[0002] In existing techniques, during femoral intramedullary nail implantation surgery, a guide pin is first inserted into the proximal femur for positioning. Then, a hollow conical opening is used to create an incision in the proximal femur, which is then placed over the guide pin, before the intramedullary nail is implanted. Because the location of the incision in the proximal femur needs to be extremely precise to ensure successful implantation of the intramedullary nail within the femoral medullary cavity, the surgeon must rely on experience to insert the guide pin into the proximal femur during the procedure. This often requires multiple insertions and removals of the guide pin to adjust the insertion point. Only after repeated X-ray fluoroscopy is the precise location of the intended incision point finally found in the proximal femur. Currently, when deviations are found on X-ray fluoroscopy after the positioning guide pin is inserted, the most common approach is to place a correction device over the positioning guide pin, and then insert another guide pin next to the positioning guide pin through the correction device. This may need to be repeated multiple times until the final guide pin position is confirmed to be correct by X-ray fluoroscopy. After that, the correction device is removed, and then a hollow opening cone is placed on the guide pin in the correct final position to make an opening in the proximal femur. This method of adjusting the guide pin and opening is quite cumbersome, and multiple fluoroscopy sessions will also increase the X-ray exposure damage to both the patient and the surgeon.

[0003] Therefore, it is necessary to provide a new honeycomb-type proximal femoral opening cone to solve the above-mentioned technical problems. Utility Model Content

[0004] The technical problem solved by this utility model is to provide a honeycomb proximal femoral opening cone that is easy to use, can accurately adjust the opening position, thereby improving the opening efficiency, ensuring the proper placement of the femoral intramedullary nail, shortening the operation time, and reducing the harm of X-ray fluoroscopy to doctors and patients.

[0005] To solve the above-mentioned technical problems, the honeycomb proximal femoral opening cone provided by this utility model includes: a guide rod, an opening cone head fixedly installed at one end of the guide rod, a handle fixedly installed on the side of the guide rod away from the opening cone head, and a positioning guide hole opened at the center of the end of the guide rod away from the opening cone head, the positioning guide hole penetrating the opening cone head.

[0006] Preferably, the guide rod has a plurality of corrective guide holes at the end away from the open cone, and the corrective guide holes penetrate the open cone.

[0007] Preferably, the number of the correction guide holes is four, and the distances from the center of the four correction guide holes to the center of the positioning guide hole are 3mm, 5mm, 7mm and 10mm, respectively.

[0008] Compared with related technologies, the honeycomb-type proximal femoral opening cone provided by this utility model has the following beneficial effects:

[0009] This invention provides a honeycomb-type proximal femoral opening cone. With the positioning guide hole 4, normal opening operations can be performed when the positioning guide pin is in the correct position, ensuring the opening position matches the femoral intramedullary nail implantation position. Simultaneously, with multiple correction guide holes 5, the opening position can be adjusted when the positioning guide pin inserted into the proximal femur deviates, thus ensuring the correct implantation of the femoral intramedullary nail. The handle 3 allows for convenient operation of the opening cone 2 for opening operations. Attached Figure Description
