Abstract
The invention relates to an instrument for orthopedic surgery, in particular to a PFNA hip compression screw guide steel needle guide device and a hip compression screw implantation tool, and aims to provide a PFNA hip compression screw guide steel needle guide device which can finely adjust the position of a PFNA hip compression screw guide steel needle in the surgical process.
Description
Technical Field
The invention relates to an instrument for orthopedic surgery, in particular to a PFNA hip compression screw guide steel needle guide device and a hip compression screw implantation tool.
Background
The PFNA fixation is carried out on the intertrochanteric fracture, the implant for the operation comprises a main nail and a hip joint compression screw, the hip joint compression screw plays a supporting role, the diameter ratio of the bone of a hip joint is smaller and is only 2-3 cm, so the position requirement of the hip joint compression screw is accurate, the PFNA hip joint compression screw is required to be in a right side position and is required to be in the center of a femoral neck, the requirement is not easy to meet, a hip compression screw guide needle needs to be adjusted for many times in the operation, the conditions of upper right position (shown in figure 1) or lower side position (shown in figure 2) are very easy to occur in the operation process, when the conditions occur, an operator needs to take out the nail, then adjusts the position of the main nail, then aims by a sighting device to re-drive the hip joint compression screw, and if the position is not appropriate, the operation needs to be repeated, in a word, a little deviation needs to be adjusted for many times, all depending on hand feeling, the operation time and the radiation amount are increased, and the pain of a patient is increased invisibly.
In this context, we have devised an improvement to the solution of this patent, considering that the adjustment cannot be done with fine adjustment of the guides.
Disclosure of Invention
Aiming at the defects in the prior art, the invention aims to provide a PFNA hip compression screw guide steel needle guide device which can finely adjust the position of a PFNA hip compression screw guide steel needle in the operation process.
In order to solve the technical problems, the invention provides the following technical scheme:
a PFNA hip compression screw guide steel needle guide device is arranged in a hollow rod shape, one end of the PFNA hip compression screw guide steel needle guide device is provided with more than two guide holes, the center of the PFNA hip compression screw guide steel needle guide device is provided with a main guide hole, and at least two adjusting holes are arranged around the main guide hole.
Preferably, the number of the adjusting holes is three, the adjusting holes are respectively distributed above, below and on the right side of the main guide hole, the adjusting holes above and below are parallel to the main guide hole, and the right-side adjusting hole and the main guide hole form an included angle of 2-5 degrees.
Preferably, the number of the adjusting holes is two, the two adjusting holes are respectively arranged above the main guide hole and on the right side of the main guide hole, the upper adjusting hole is parallel to the main guide hole, and the right adjusting hole and the main guide hole form an included angle of 2-5 degrees.
A hip compression screw implantation tool provided with the PFNA hip compression screw guide steel needle guide of any of claims 1-3.
The technical scheme is that the hollow rod-shaped guide hole is arranged at one end of the hollow rod-shaped guide hole, more than two guide holes are arranged, the center of the hollow rod-shaped guide hole is provided with a main guide hole, and at least two adjusting holes are arranged around the main guide hole. When the guiding device is used, if the aiming position of the main guiding hole does not meet the operation requirement, a doctor can select the adjusting hole beside the main guiding hole to finely adjust the position of the steel needle according to the display of the operation monitoring device, so that the guiding area of the guiding device is increased, the position of the main nail does not need to be adjusted repeatedly, and the operation pain of a patient is reduced to a certain extent.
The adjusting holes are arranged in three numbers and respectively distributed above, below and on the right side of the main guide hole. Therefore, if the hip joint compression screw is deviated, an operator can select an adjusting hole below the main guide hole to implant the screw, if the screw is deviated, the adjusting hole above the main guide hole can be selected to implant the screw, and if the screw is deviated in lateral position, the adjusting hole on the right side can be selected to implant the screw.
According to the technical scheme, the two adjusting holes are arranged above and on the right side of the main guide hole respectively, the guide hole on the upper side is parallel to the main guide hole, the right adjusting hole and the main guide hole form an included angle of 2-5 degrees, and the guide device with the structure needs to be turned over for use even in the upper part and the lower part.
A hip compression screw implantation tool, which comprises the PFNA hip compression screw guide steel needle guide device of the technical proposal.
The technical scheme has the advantages of simple structure and convenient use, effectively increases the steel needle driving area of the guider, can quickly complete the operation under minimally invasive operation, and can be popularized and used in orthopedics.
