Abstract
The utility model relates to Kirschner pins with holes, belonging to the orthopaedics appliance. The utility model is characterized in that both ends of a pin body are respectively provided with a hole, and one end of the pin body is provided with a pinpoint. After the Kirschner pin is positioned at the fracture position, the Kirschner pin is fixed through a needle wire, and thus the defect of easy sliding of the existing Kirschner pin can be overcome. The needle body stays very short at the ectosteal, the mechanical stimulation to the tissue skin by the needle body can be effectively avoided, and thus the postoperative pain of the patient can be relieved.
Description
This utility model belongs to orthopedic instrument, particularly relates to a kind of kirschner wire with hole.
Kirschner wire be used to the to fracture history of the existing many decades of internal fixation, its the bone fracture bone fracture disease patient that appears as has brought Gospel, also changed original to the treatment of fractures method, it has simple, easy to use, the fixing effective characteristics of operation technique, but in the life-time service process, discovery is with Kirschner wire fixedly during fracture site, the loosening migration of needle body often appears, cause the fracture para-position bad, and since the Kirschner wire bone to reserve backshank outward long, to problems such as artificial skin mechanical stimuluss, cause unnecessary misery to the patient, and prolonged the fracture site healing time.People have also done a large amount of work for improving Kirschner wire, the patent that is called " Pressure needle plate for osteosynthesis " (patent No. 9322157.x) as Patent Office of the People's Republic of China's bulletin on June 1st, 1994, it is to be provided with screw thread at an end that has Kirschner wire now, is added with on screw thread and steps up pad and nut.Though it has solved the loosening problem of Kirschner wire, but because it is the unidirectional nut that has, during other end operation, need bending, after operation, cut off the unnecessary needle tail part of nut end face, after will causing union of fracture like this, when Kirschner wire being taken out,, get the problem of pin difficulty because the screw thread position is destroyed as need.
The purpose of this utility model provide a kind of simple in structure, fixing reliable, install, remove very easy kirschner wire with hole.
The technical solution of the utility model is: a kind of kirschner wire with hole, it is characterized in that respectively having a hole 3 at needle body 3 two ends, and an end of needle body 2 is provided with needle point 1; Hole 3 can be circular hole, slotted hole or polygonal hole; Needle point 1 can be taper shape or polygonal pyramid shape or triangle.
Characteristics of the present utility model are: it had both kept original Kirschner wire advantage easy to use, have fixing reliable again, can effectively prevent the shortcoming that Kirschner wire slides easily, gets loose after fixing, and the outer reservation of the two ends bone of pin is extremely short, reduce or avoided of the mechanical stimulus of pin two ends artificial skin, the misery of patient's postoperative is reduced, and after the union of fracture, the taking-up of Kirschner wire is also very convenient.
Embodiment of the present utility model is explanation in detail in conjunction with the accompanying drawings.
Accompanying drawing 1 is this utility model structural representation.
Accompanying drawing 2 uses sketch map for this utility model.
As shown in Figure 1, 2, after patella 5 fracture, fracture site 6 is resetted, patella 5 after adopting kirschner wire with hole fracture is located, and passes the hole 3 at needle body 2 two ends with fine needle silk 4, and patella 5 is fixed, needle body 2 just can not become flexible in vivo like this, can make simultaneously the outer reservation of backshank bone very short, avoid stimulation, reduce patient's misery artificial skin; One end of needle body 2 is provided with needle point 1, adopts direct motion or retrograde fixing operation all unaffected during operation.After the fracture site healing, only need fine needle silk 4 is removed, extract kirschner wire with hole.
