Abstract

The utility model discloses a kind of absorbable aft rib fracture dislocation fixators, the frid made of human body degradation material is as rib cage girder, it extends upward to form transverse process beam in the one end of rib cage girder along its length, fixation hole is distributed on rib cage girder and transverse process beam.The fixator of the utility model is l-lactic acid successively by made of injection molding, reinforcing.Effective solution is with the fracture of rib and backbone transverse process and capitulum costae dislocation problem within the two sides 120mm of backbone center, the implantation of the fixator avoids the drawbacks of existing metallic weapon second operation takes out, the strong intensity of metallic weapon can not only be reached using fixator made of l-lactic acid material, the deficiency of existing instrument single therapy purpose is also overcomed simultaneously, and can preferably reach therapeutic effect.

Description

Absorbable aft rib fracture dislocation fixator

Technical field

The utility model belongs to medical instruments field, is related to fixator, and in particular to one kind is made of l-lactic acid High-intensity absorbable, within the two sides 120mm of backbone center fracture of rib and backbone transverse process and capitulum costae dislocation fix Fixator.

Background technique

L-lactic acid is a kind of new medical material that the good Wholly-degradable of biocompatibility absorbs, and degrades and produce Object is non-toxic to humans, has been widely applied in medical field to fix material in Thermosensitive Material Used for Controlled Releasing of Medicine, material implanted, orthopaedics Material etc. has good clinical value.

The fracture of aft rib and dislocation account for about 20% or so in orthopaedics thoracic injury fracture, but at present clinically, based on flesh herein Meat is abundant and thick and solid, and when dissected amount of bleeding is big and because close to backbone, nerve is abundant, and the reasons such as operation risk height encounter such disease Shape selects not handle or at most implement outer fixed disposition, and existing outer fixed treatment instrument has titanium plate, stainless steel plate or memory Alloy fixator etc., these apparatus structures are complicated, and operating time is long, and second operation is needed after implantation, take out implantation material, increase doctor Work difficulty；And existing part thereof is the instrument of individual treatment fracture or dislocation, cannot reach simultaneously treatment fracture and The effect of dislocation is unable to satisfy the use needs of aft rib fracture dislocation patient.

Utility model content

In order to solve the above-mentioned problems in the prior art, the utility model provides one kind and is made of l-lactic acid High-intensity absorbable aft rib fracture dislocation fixator.

In order to solve the above-mentioned problems in the prior art, the utility model adopts the following technical solution: one kind can inhale Aft rib fracture dislocation fixator is received, the frid made of human body degradation material is as rib cage girder, in rib cage girder along its length One end of degree extends upward to form transverse process beam, and fixation hole is distributed on rib cage girder and transverse process beam.

Preferably, human body degradation material is l-lactic acid material.

Preferably, frid is the arc frid with curvature inward curl.

Preferably, transverse process beam is that the one end of rib cage girder along its length extends upward step and formed, and with rib cage girder It is parallel.

The fixation hole is that absorbable spicule is implanted into fixation hole.

The utility model has the beneficial effects that: the fixator of the utility model is by l-lactic acid successively by note Made of modeling, reinforcing.Effective solution is with the fracture of rib and backbone transverse process and capitulum costae within the two sides 120mm of backbone center Dislocation problem, the implantation of the fixator avoids the drawbacks of existing metallic weapon second operation takes out, using l-lactic acid material Fixator made of expecting can not only reach the strong intensity of metallic weapon, while also overcome existing instrument single therapy purpose Deficiency, and can preferably reach therapeutic effect.Several fixation holes are selected for doctor, make to fix more flexible effective.

Detailed description of the invention

The structural schematic diagram of Fig. 1 the utility model；

The top view of Fig. 2 the utility model Fig. 1；

The sectional view along A-A of Fig. 3 the utility model Fig. 1；

In figure: 1- rib cage girder 2- transverse process beam 3- fixation hole.

Specific embodiment

The utility model is further explained and is illustrated with reference to the accompanying drawing；

As shown in Figure 1, a kind of absorbable aft rib fracture dislocation fixator, has curvature made of l-lactic acid material Arc frid as rib cage girder, extend upward step in the one end of rib cage girder along its length and formed and rib cage girder phase Bolt fixing hole is distributed on rib cage girder and transverse process beam as shown in Fig. 2,3 in parallel transverse process beam.

As shown in figure 3, being successively made by injection molding, reinforcing of l-lactic acid, rib cage girder is according to backbone center two The aduncate arc frid in two sides is made in width within the about 120mm of side, and the number of fixation hole increases with the length of rib cage girder 1 It adds deduct few, is evenly distributed on rib cage girder and transverse process beam, transverse process beam 2 raises upward with rib cage girder 1 in step-like.Make The inner wall of used time, the rib cage girder 1 of inward curl are contacted with rib surface, raised transverse process beam 2 and backbone transverse process face contact, choosing The fixation hole 3 for being scheduled on fracture of rib line two sides and transverse process beam centre is implanted into absorbable spicule, 3 position of fixation hole and fixed angles The selection of degree depends on patients with fractures and dislocation situation, several fixation holes 3 are selected for doctor, makes to fix more flexible effective.Together When achieve the effect that treatment fracture and dislocation, fixator natural degradation after recovery, without second operation take out.
