Simple palm phalanx fracture external fixation support connecting screwTechnical Field
The utility model belongs to the technical field of medical instruments, and particularly relates to a simple palm and finger bone fracture external fixing support connecting screw.
Background
Metacarpophalangeal fracture is a common fracture in hand surgery in clinic, and poor healing can affect the function of hands. Although the fixation of the kirschner wire is a minimally invasive operation, the steel wire is easy to loosen and slip, the fracture is not healed, the joint function is influenced by the transarticular fixation, the early rehabilitation after the operation is not facilitated, and the like. The existing external fixation support for palm fracture occupies too large space when in fixation, which affects the appearance and hand movement after operation and causes inconvenience to patients.
Disclosure of Invention
Aiming at the technical problems, the utility model provides a simple palm phalanx fracture external fixation support connecting bolt, which has the specific technical scheme that:
a palm phalanx fracture external fixation support connecting bolt comprises a fixing bolt and a fixing nut, wherein a transverse hole and a vertical hole are formed in the fixing bolt.
The utility model has simple structure, can fix metacarpal and phalangeal fractures in vitro, has small volume of the fixing device, does not influence patients, can firmly fix fractured ends, can carry out early joint movement on the patients, avoids tendon and joint adhesion after operation, and is beneficial to healing of fractures.

Detailed Description
As shown in fig. 1 to 3, the connecting bolt for the external fixing bracket for metacarpophalangeal fracture comprises afixing bolt 1 and afixing nut 2, wherein thefixing bolt 1 is provided with atransverse hole 101 and avertical hole 102.
As shown in figure 3, when the utility model is used, thekirschner wires 4 are placed at two ends of the broken part of theskeleton 4 through an operation, thekirschner wires 4 penetrate through thevertical holes 102 on thefixing bolts 1, thekirschner wires 4 and thefixing bolts 1 are locked and fixed through thefixing nuts 2, among a plurality offixing bolts 1, anotherkirschner wire 4 penetrates through thetransverse hole 101 on thefixing bolt 1 and is fixed through thefixing nut 2 at the other side, and a plurality offixing bolts 1 can be connected and fixed according to the fracture condition and the requirement.
