Description
Technical Field
The invention relates to the technical field of surgical instruments, in particular to an integrated disposable laser positioning guide pin for intramedullary nail hole positioning.
Background
In the prior art, two ends of an intramedullary nail are fixed by screws, and when the method is used for fixing the fracture, a very important and very troublesome work is to find out the positions of fixing holes at the two ends of the intramedullary nail so as to facilitate the drilling and fixing of bones. Since the intramedullary nail is implanted in the medullary cavity and covered by bones and muscles, orthopedists cannot visually know the exact position of the fixation hole, and therefore, the fixation hole is usually positioned by means of an X-ray machine. The use of X-ray machines, in addition to being costly, has the major disadvantage of causing additional radiation dose absorption by the patient and physician. Even with the relevant precautions, the radiation dose that accumulates over time is significant for a physician who is often required to perform such a procedure. Therefore, orthopedists generally do not adopt the method and mostly do it with hands.
The free-hand operation means that a doctor performing an operation can simulate and judge the approximate position of the fixing hole in vitro near the fracture part according to a steel nail with the same size and the experience of the doctor, and drill a hole at the presumed part, so that the position of the fixing hole can be found out smoothly and fixed by utilizing a trial and error method. However, since the diameter of the fastening hole is only about 5mm, and slight deviations can lead to the fastening screw not being able to be locked in, the task of finding the fastening hole usually takes a rather long time. According to statistics, even a highly experienced physician may take more than 20, 30 minutes to complete on average. Often, the bone near the drilled site is also damaged by multiple drilling, causing additional injury to the patient. Therefore, if there is a method to allow the doctor to see the fixing holes hidden in the bone instantly on the operation site with naked eyes or on the display screen without the negative effect of the X-ray machine, it is a great gospel to both the doctor and the patient.
Disclosure of Invention
The invention aims to provide an integrated disposable laser positioning guide pin for intramedullary nail hole positioning, which solves the problem that doctors cannot visually know the exact position of an intramedullary nail fixing hole in the prior art, adopts light generated by low-power laser to penetrate through the position of an intramedullary nail screw hole and then penetrate through human bone and muscle tissues, and can visually see a light spot to drill a bone hole.
