Abstract

The utility model relates to a thermoplastic splint for external fixation of fracture. Metal joints which are especially made are installed on the elbow part, the knee part, the coax part and the ankle part. A fracture site can be externally fixed and a joint can carry out necessary activities. The thermoplastic splint is used for preventing dislocation of an early fracture and a medium-term fracture and curing a fracture as soon as possible. The utility model has the advantages of light weight, good air permeability, good elasticity and high strength.

Description

The thermoplastic splint

This utility model relates to a kind of fracture external fixator, especially a kind of articulated thermoplastic splint.

Utility model " clamping plate of treatment fracture " (patent No. 87216889) discloses a kind of thermoplastic splint's product, and these clamping plate after upper and lower limb is fixing, can not make limbs joint carry out necessary activity in actual clinical.

The purpose of this utility model provides a kind of joint part that can make and carries out the thermoplastic splint of required activity after external fixation of fracture.

The purpose of this utility model is achieved in that

Adopt polypropylene board, after cutting out according to anthropometric dummy, heat, soften, processing, molding, vertically be cut into three parts after the cooling and install special metal hinge, be stained with the polyethylene liner, evenly get air-vent, load onto members such as metal joint and nylon bracelet, the tension of nylon bracelet fixes fracture site, and metal joint guarantees that the joint can be movable.

This utility model is compared with other clamping plate, and fracture site is fixing reliable, and band is with convenient, and build scope difference can be adjusted.Metal joint can be locked in a certain angle, also certain rotation can be arranged, and makes things convenient for patient's ancon, hip, knee or ankle to carry out essential activity, improves the biologos of fracture site, promotes the healing early of fracture.

Below in conjunction with drawings and Examples this utility model is described further:

Among Fig. 1,1-cervical region clamping plate forestock, 2-butt

3-nylon bracelet, 4-air-vent

Among Fig. 2,3-nylon bracelet, 4-air-vent

Two anter 6-rear panels of 5-clamping plate

Among Fig. 3, two anter 6-rear panels of 5-clamping plate

7-hinge, 8-metal joint

9-big arm or big leg splint 10-forearm or big leg splint

11-semi-circular plate, 12-metal connection strap

13-rotating shaft, 14-fixed screw

15-small sircle hole, 16-lock(ing) bolt

17-circular hole

With height 1.72cm, body weight 65kg, the human body of being well-proportioned is done standard, gets neck circumference, breast waistline, upper limb, lower limb plaster model respectively, cuts out polypropylene board according to model, puts into drying baker or panel heater and heats to about 200 ℃.After softening immediately in model surface machine-shaping, behind the cooling and shaping, vertically be cut into two parts (cervical region) or three parts (breast waist, extremity) respectively, with buffing machine that surface finish is smooth, upper and lower limb is installed the metal hinge, and the lined with polyethylene foam is evenly got air-vent, install metal joints such as hip joint, knee joint, ankle joint, shoulder joint, elbow joint, load onto the nylon bracelet so that clamping plate reach fixed purpose at correct position.

Among Fig. 1, forestock of cervical region clamping plate (1) and butt (2) are through the nylon bracelet (3) of both sides, and tension fixes cervical region, in the holder of front and back uniform air-vent (4) are arranged.Neck circumference adjustable extent 36-46cm.

Fig. 2 mesothorax waist clamping plate are made up of two anters (5) and a rear panel (6).Utilize hinge (7) to connect, anter can pass through hinge (7) and come activity, makes things convenient for the use of clamping plate, can be so that breast waist clamping plate are fixed chest adjustable extent 80-104cm after nylon bracelet (3) tension on the anter.

The clamp region principle of upper and lower limb is similar to breast waist clamping plate, is the size difference, big arm week footpath 24-36cm, forearm 20-30cm, thigh 40-50cm, shank 24-42cm.

Big arm splint (9) and little arm splint (10) are bound up by metal joint (8), and metal joint (8) is made of 6 parts, sees Fig. 3.Semi-circular plate (11) and metal connection strap (12) link together by rotating shaft (13), the outer edge of semi-circular plate is drilled with row's small sircle hole (15), metal connection strap (12) can rotate with rotating shaft (13), makes limbs carry out essential activities such as bending, plays the effect in joint.Early stage in fracture, insert in the different apertures (15) by lock(ing) bolt (16), make two metal connection straps form certain angle, scope is at 30-180 °.Several circular holes (17) are also arranged on the metal connection strap, the metal connection strap is fixed on the clamping plate, and can utilize fixed screw (14) to be inserted in different circular holes, the flexible scope 16cm of metal connection strap according to the needs of limbs length.

In like manner, hip joint, knee joint, the ankle joint between leg splint and the foot holder also is to connect by the identical metal joint of structure.

In addition, on big arm splint (9) and breast waist clamping plate (6), fix a supporting bracket with screw, supporting bracket is " II " shape structure that several bonding jumpers are formed; the available metallic rod of little arm splint (10) supports, and lifts the purpose of shoulder joint abduction thereby reach upper limb.

This utility model is suitable for extremity or spinal column war wound, fracture early, mid-term external fixation, prevent the fracture dislocation, being particularly suitable for big forearm or thigh and calf all needs fixed patient.It is in light weight, avirulence, and intensity is big, and good springiness is comfortable attractive in appearance, and routine effect is remarkable surplus in the of clinical 3000.
