As shown in fig. 4, the method of use:
firstly, preoperative preparation: sterilizing and packaging the novel Kirschner wire at high temperature for later use;
secondly, the surgical process of the Kirschner wire tension band is as follows: after combined anesthesia or general anesthesia takes effect, the affected limb is disinfected and paved conventionally; secondly, the blood flow blockage of the near end of the thigh is finished by the air bag tourniquet; making an incision at the front center of the knee, and performing operations such as blood clot removal, patella reduction, joint cavity flushing and the like after the fractured end is exposed; the patella reduction forceps are used for temporarily fixing the fracture, 2 novel Kirschner wires are parallelly driven into the patella from the 5mm distance of the cartilage surface, the patella reduction forceps stop when the easy-to-break part is pressed close to the superior level of the patella, one of the double titanium cables is fixed by being annularly wound around the patella and penetrating through a below-arranged Billerplate hole of the Kirschner wires, and the other of the double titanium cables penetrates through a side I hole of the Kirschner wires and is tightened and fixed after the cross of the 8-shaped Bill wires in front of the patella. Cutting off the redundant part of the Kirschner wire body; breaking off the tail part of the kirschner wire at the position easy to be broken; and fifthly, finishing subsequent stitching after the patella is proved to be well restored by the C-shaped arm X-ray machine.
Thirdly, post-operation review: after the operation, the operation is carried out for one, two, three, six months and one year, and the fracture can be taken out and fixed internally after being healed;
fourthly, taking the internal fixation operation process: after combined anesthesia or general anesthesia takes effect, the affected limb is disinfected and paved conventionally; completing the blood flow blockage of the near end of the thigh by means of an air bag tourniquet; taking 3cm above the original incision, finding two Kirschner wires and two titanium cables, cutting the titanium cables, drawing out the two titanium cables and drawing out the two Kirschner wires; c-shaped arm X-ray machine confirms that there is no residual internal fixation and then completes the subsequent stitching.
Example 1
The patient, male, is 59 years old, falls and causes the fracture of the right patella, is admitted to the hospital 2 h after injury, and X-ray film and three-dimensional CT show the fracture of the right patella before operation. The patient is given perfect preoperative examination, the contraindication of the operation is eliminated, and the right patellar fracture incision reduction internal fixation operation is performed in the selected period: after combined anesthesia or general anesthesia takes effect, the affected limb is disinfected and paved conventionally; secondly, the blood flow blockage of the near end of the thigh is finished by the air bag tourniquet; making an incision at the front center of the knee, and performing operations such as blood clot removal, patella reduction, joint cavity flushing and the like after the fractured end is exposed; fourthly, temporarily fixing the fracture by using patella reduction forceps, parallelly driving 2 Kirschner wires 5mm away from the cartilage surface into the patella, circularly pricking one of the double titanium cables around the patella, and tightening and fixing the other of the double titanium cables after the other of the double titanium cables is crossed in a shape of 8 in front of the patella; and fifthly, finishing subsequent stitching after the patella is proved to be well restored by the C-shaped arm X-ray machine. The postoperative March patient rechecks the X-ray to prompt that the 8-shaped titanium cable falls off, the Kirschner wire withdraws the needle, and the patient complains of the right knee pain.
Example 2
The patient, female, was 45 years old, left patellar fractured due to traumatic injury, was admitted to the hospital 24h after injury, and left patellar fractured was shown by X-ray film and three-dimensional CT before surgery. The patient is given perfect preoperative examination, the contraindication of the operation is eliminated, and the left patella fracture incision reduction internal fixation operation is performed in a selected period: after combined anesthesia or general anesthesia takes effect, the affected limb is disinfected and paved conventionally; secondly, after an ideal anesthesia effect is achieved, the blood flow blockage of the near end of the thigh is finished by means of the air bag tourniquet; making an incision at the front center of the knee, and performing operations such as blood clot removal, patella reduction, joint cavity flushing and the like after the fractured end is exposed; fourthly, temporarily fixing the fracture by using patella reduction forceps, driving 2 novel Kirschner wires 5mm away from the cartilage surface into the patella in parallel, stopping when the easily-broken part is close to the superior patella, performing cerclage on one of the double titanium cables around the patella, penetrating through a cerclage hole below the Kirschner wires, penetrating through a cerclage hole on the lateral side of the Kirschner wires, crossing and then tightening and fixing the two titanium cables after the 8-shaped wires are crossed, and breaking the tail part of the Kirschner wires at the easily-broken part; and fifthly, finishing subsequent stitching after the patella is proved to be well restored by the C-shaped arm X-ray machine. The postoperative March patient reexamines the X-ray to prompt that the internal fixation is fixed in place, and the patient has no special discomfort and the knee joint can move.
Comparison of the use of the current k-wire example 1 with the surgical use of k-wire example 2 of the present application reveals that (i) soft tissue irritation is small: because the traditional needle tail is cut by a strong shear, the needle tail is rough after being cut and is buried in soft tissues to cause irritation of different degrees, and patients feel pain when the needle tail is buried in the soft tissues; secondly, the pin tail is easy to break: because the local operation space of the incision is limited, the operation of breaking the needle in the incision is very laborious and difficult, time and labor are wasted, and the novel Kirschner wire has a design of easy breaking and can be easily broken by bare hands; avoiding the splayed titanium cable from falling off: the traditional method is characterized in that after the traditional method is bent by 90 degrees, a 8-shaped titanium cable is bound, the splayed titanium cable is usually separated after operation due to the fact that a Kirschner wire is not suitable for closed loop, a novel Kirschner wire is reserved with a needle hole I as a closed loop, and the titanium cable cannot be separated from the splayed titanium cable; and fourthly, the problem that the traditional Kirschner wire can be withdrawn after operation due to the reasons of osteoporosis and the like is solved, and the novel Kirschner wire is reserved with II holes and is firmly fixed by passing through a cerclage steel cable, so that the Kirschner wire cannot be withdrawn easily.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
