Description

A kind of minimally invasive dynamic external fixing rack of finger

Technical field

The utility model relates to fractures technical field, in particular to a kind of minimally invasive dynamic external fixing rack of finger.

Background technique

Care of fractured fingers is the common disease of orthopaedics, and heal the bad function of will affect hand, therefore the reduction of the fracture is healed, and is restored Finger-joint function, to restoring, finger function is extremely important, and treatment method is mainly first that fracture involution is normal with external force Position, then imposes fixed device, allows affected part self-heal after a period of time, since treatment time is not of short duration, if solid Determine that mode is improper, will the serious daily routines for interfering patient, in the prior art, generally using external fixer to care of fractured fingers portion Position is fixed, and is fixed entire fingerhold using upper and lower two clamping plate, due to taking whole fixation, finger nothing during fixation Mobility needed for method provides dynamic moving is only capable of providing fixed support, since fracture site is not influencing the case where restoring Under, slight activity is early carried out as far as possible and is taken exercise, and finger is completely fixed the later period recovery that can seriously affect patient.

Utility model content

The main purpose of the utility model is to provide a kind of minimally invasive dynamic external fixing racks of finger, can effectively solve background The problems in technology.

To achieve the above object, the technical solution that the utility model is taken are as follows: a kind of minimally invasive dynamic external fixing rack of finger, packet Damage phalanges is included, the two sides of the damage phalanges are respectively proximal phalange and distal phalange, and the proximal phalange is close to the one of palm Side phalanges, the proximal phalange are provided through the first fixed pin, and the distal phalange is provided through the second fixed pin, and described first The both ends of fixed pin bend setting, and mutually fix with the second fixed pin, and the damage phalanges is provided through correction fixed pin, and First fixed pin, the second fixed pin and correction fixed pin are arranged at same plane, the correction fixed pin both ends bending There is lantern ring, the lantern ring is socketed in the two sides of the first fixed pin, is cased with protective case, the guarantor on the outside of the finger of the damage phalanges Sheath is provided with transparent windows.

Preferably, first fixed pin, the second fixed pin and correction fixed pin are Kirschner wire, and described first is fixed Needle is fixed with the second fixed pin by medical rubber band.

Preferably, the Kirschner wire diameter is 1.2 millimeters or 1.5 millimeters.

Preferably, the side of the protective case is provided with socket, and the socket is plugged with fixed plate, the fixed plate it is another One end is fixed by fixing belt and palm.

Preferably, the protective case is Semi-folding setting, and the protective case is fixed by snap.

Preferably, silica gel protective pad is provided on the inside of the protective case.

Compared with traditional technology, the beneficial effect that the utility model generates is:

1, the minimally invasive dynamic external fixing rack of the finger, dislocation is that dorsal offset merges articular surface half between mostly referring to Or one third fracture, usual ligament completely can be with early functional exercises without fracture, functional activity under the small early protection of wound, It can guarantee the carry out early exercise that finger can be slight, guarantee that finger restores very fast.

2, the minimally invasive dynamic external fixing rack of the finger, saves open comminuted fracture suitable for phalanges, condition of not threading a needle, Crucial face collapses, and base bottom crushes and collapses, and no support force fracture, tendon soft tissue is good, can be by the way that the first fixed pin is arranged It is fixed with the second fixed pin to whole, recovery effects are good.

3, the minimally invasive dynamic external fixing rack of the finger can be fixed postoperative injured finger by setting protective case Protection, and observed by recovery situation of the transparent windows to finger.
