Abstract

The utility model discloses an external fixation bracket for fracture, which belongs to the technical field of surgical medical instruments. For solving technical problems, the utility model providesa novel external fixation bracket for fracture, which has the advantages of portability, flexile clinical operation, secure fixation, humanization and the like. The utility model adopts the technicalscheme as follows: the external fixation bracket comprises a bracket body and a retaining screw, the bracket body takes the shape of a strip, a dual-ring-shaped round hole is formed in the middle partof the bracket body, and inner wall screw threads are formed in the interior of the bracket body, elliptical inner-concave grooves are formed at the periphery of the bracket body, the retaining screwis provided with a self-drilling and self-tapping drill bit, bolt screw threads are formed in the middle part of the screw rod, and a hexagonal inner-concave rotation hole is formed on the bolt at the top part. The external fixation bracket is helpful to tissue growth and protection of patients after operation, and meanwhile, tensile force for growth and exercise of skeleton and muscle can be relieved.

Description

A kind of external fixation of fracture support

[technical field]

This utility model relates to a kind of external fixation of fracture support, belongs to surgical medical equipment, surgery fracture clinical operation equipment technical field.

[background technology]

In surgery fracture clinical operation equipment is used, traditional external fixation of fracture support is of rude workmanship, heavy, structure is complicated, volume is big, operation is dumb, full thread exterior fixation bracket for example, fixing two ends only, operate both dumb, also insecure, be not easy to clinical use and tissue growth and protection, influence union of fracture; The big complicated fixed support clinical manipulation of other is very inconvenient, and wound is big, easily brings bigger misery to the patient, is unfavorable for that the patient recovers.

[utility model content]

Technical problem to be solved in the utility model is to provide a kind of novel external fixation of fracture support; light, characteristics such as clinical manipulation flexible, fixation, hommization that this fixed support has; especially consider convenient and patient affected part tissue growth and protection in the operation, the big small sircle hole design of fixed support double-ring is simultaneously with respect to the growth of skeleton and muscle, the tension force that motion is brought.

For solving the problems of the technologies described above, the technical scheme that this utility model adopted is:

A kind of external fixation of fracture support is provided, mainly comprise support body and hold-down screw, support body is the flat strip, the middle part is arranged and to be provided with that many groups are used for fixing and the double-ring circular hole of mobile hold-down screw, and two circles of double-ring circular hole intersect, small one and large one, two circle and the equal hollow outs of cross-shaped portion, inside is provided with the inner thread of the screw that is used to be tightened, and support body both sides and periphery are provided with the finger groove of a plurality of oval indents, is convenient to the clinical operation operation and grips.

The size of described hold-down screw middle part screw rod and screw thread and the medium and small circular-hole internal-wall size of double-ring circular hole and screw thread adapt, double-ring circular hole two circle intersection hollow outs, the nearest inner diameter in crossing hollow out place should be slightly larger than the diameter of hold-down screw middle part screw rod, so that hold-down screw moving and the location in two holes.

Described hold-down screw has the self-drilling self-tapping drill bit, triangle pointed drill shape in the shape of a spiral, the middle part screw rod is provided with the screw flight that adapts with the medium and small circular-hole internal-wall screw thread of double-ring circular hole, and the top bolt is provided with the commentaries on classics hole of hexagonal indent, is used for throw and screws or loosen screw.

The beneficial effects of the utility model are: have big or small double-ring circular hole owing on this utility model support body, refer to groove and the design of self-drilling self-tapping drill bit hold-down screw; in use can flexible operating, fixation; has hommization; be particularly advantageous in convenient and patient affected part tissue growth and protection in the operation; help alleviating the growth of skeleton and muscle, the tension force that motion is brought, fully satisfy the demand of clinical operation.
