Description

A kind of outer fixed structure of Elbow Fracture

Technical field

It the utility model is related to technical field of medical equipment, more particularly to a kind of outer fixed structure of Elbow Fracture.

Background technology

Bending and stretching for elbow joint enables the hand of the mankind is far and near to move freely, and the performance of this leverage opponent function has Particularly important meaning.Although elbow joint is only capable of doing flexion and extension around single axis, Elbow Fracture such as influences elbow pass The flexion-extension motion of section and the spinfunction of forearm, so that adverse effect is played in the performance of opponent's function.Near common elbow joint Fracture includes supracondylar fracture of humerus, Intercondylar fracture, epicondylus medialis fracture, outside upper condylar fracture, olecranal fracture etc..These fracture with Person is in the majority with involving articular surface for unstable fracture, most of to have surgical indication, it is necessary to open reduction, and it is postoperative generally still need to it is auxiliary With fixed outside gypsum or fixture.

Before the utility model, Chinese patent (CN201520231928.0) discloses the adjustable fixed branch of elbow joint Tool, and by the mating reaction of the velcro in the thread gluing on redundant constraint band and restraint strap and front side clamping plate, front side is pressed from both sides Plate links together with butt clamping plate；This mode is although easy to disassemble, is conducive to doctor to patient wound and Skin observing；Together When, since operation difficulty is relatively low, patient can Dismountable, easy to patient carry out training for recovery.But the stability of thread gluing Difference, fixation is unreliable, extremely easily occurs loose and causes patient's secondary injury；And it cannot be guaranteed the elasticity of every restraint strap It is all consistent, ancon unbalance stress is be easy to cause, so as to cause the discomfort of patient, or even not expected shift separation can be caused.

Utility model content

In view of this, the purpose of this utility model is to provide a kind of outer fixed structure of Elbow Fracture, can make outer fixation Structure is fixed reliably, prevents that it is loose, while ensures each position uniform force of patient's ancon, is avoided the occurrence of not expected Shift separation.

The utility model solves above-mentioned technical problem by following technological means：

A kind of outer fixed structure of Elbow Fracture, including the first L-shaped backplate and the second L-shaped backplate, the first L-shaped backplate It is arcuate structure with the second L-shaped backplate, L-shaped protecting groove, the L is respectively equipped with the first L-shaped backplate and the second L-shaped backplate The both sides of shape protecting groove are respectively arranged with arc locked groove, and the arc to match with arc locked groove is inserted with the arc locked groove and is locked Piece, the second L-shaped backplate are fixed on the first L-shaped backplate by the mating reaction of arc locked groove and arc locking plate.

What is reached has the technical effect that, can effectively improve the stability of outer fixed structure, fixes it reliable, avoid because Patient's secondary injury caused by loosely；It can make each position uniform force of patient's ancon at the same time, avoid because of unbalance stress And the discomfort of patient and the phenomenon of not expected shift separation is caused to occur.

Further, the first L-shaped backplate is equipped with locating slot, and the second L-shaped backplate is equipped with and locating slot phase The positioning ridge matched somebody with somebody., can be rapidly and accurately entire in first by the second L-shaped backplate lid by the mating reaction of locating slot and positioning ridge It is more convenient to be inserted into arc locked groove in arc locking plate on L-shaped backplate, shorten the activity duration, treasured is won for the rescue of early stage Your time.

Further, the rear end of the arc locking plate is equipped with anti-skid bulge, on the first L-shaped backplate and the second L-shaped backplate Equipped with grabbing groove with what anti-skid bulge matched.When dismantling outer fixed structure, from grab in groove promote anti-skid bulge by way of Arc locking plate is taken out, dismounting difficulty is significantly reduced, improves removal efficiency.

Further, the corner of the L-shaped protecting groove inner wall is equipped with elastic sponge mattress.Elastic sponge mattress can be in ancon and L Play the role of buffering between shape protecting groove, it is possible to increase the comfort level of patient's ancon, avoid caused by collision ancon secondary by Damage.

Further, it is provided with air hole in the L-shaped protecting groove.Gas permeability inside the outer fixed structure of enhancing, avoids patient Body-sensing situations such as not accommodating anaerobic bacteria growth, preventing from causing skin allergy, infection occur.

Further, the front end of the arc locking plate is wedge structure.Wedge structure can make arc locking plate quickly and arc Locked groove positions, and significantly reduces operation difficulty, improves efficiency of assembling.

The beneficial effects of the utility model：

1. the stability of the utility model is strong, the connection of two L-shaped backplates is fixed reliably, can be avoided because of two L-shaped backplates pine Dissipate and caused by patient's secondary injury；

2. the utility model can make each position uniform force of patient's ancon, avoid causing patient because of unbalance stress Discomfort and not expected shift separation phenomenon occur；

3. the utility model can be rapidly and accurately entire in one by two L-shaped backplate lids, more convenient to be inserted in arc locking plate Enter arc locked groove, shorten the activity duration, the quality time is won for the rescue of early stage；

4. the utility model can improve the protection to patient's ancon, the comfort level of ancon is improved, is avoided caused by collision Ancon it is secondary impaired；

5. the good permeability inside the outer fixed structure of the utility model, can avoid the body-sensing of patient from not accommodating anaerobic bacteria life It is long, prevent occurring situations such as causing skin allergy, infection；

6. the utility model is simple in structure, dismantles and easy to assembly quick, suitably promote the use.
