Description
Technical Field
The utility model belongs to the technical field of medical treatment rehabilitation apparatus technique and specifically relates to an external fixation support for orthopedics.
Background
The external fixing bracket for orthopedics can fix fracture and correct certain bone deformity, is an important appliance for orthopedics, is mainly used for treating fracture fixation in clinical work and is beneficial to slow healing and recovery, and consists of a stainless steel needle, a connecting rod and a steel needle fixing clamp. The annular external fixing support for recovering the lower limbs generally comprises an annular positioning plate, a connecting rod and a pressurizing fixing needle, but a matched fixing piece is lacked between the annular positioning plate and the lower limbs, so that the pressurizing fixing needle is unstable and is easy to collide and displace, and pain is brought to a patient.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defect that the pressurizing fixing needle of the existing external fixing bracket is easy to shift, the utility model provides an external fixing bracket for orthopedics, which solves the problem by uniformly arranging an elastic positioning piece matched with the pressurizing fixing needle around an annular positioning plate.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides an external fixation support for orthopedics, includes that annular positioning plate and circumference insert the fixed needle of pressurization of establishing on annular positioning plate, and annular positioning plate is provided with three at least, and annular positioning plate parallel arrangement just is through the connecting rod fixed connection who runs through the plate body, inserts the fixed needle outside correspondence of the pressurization of establishing on annular positioning plate and is provided with the elastic component that is used for the needle body direction and protects.
Furthermore, the elastic element comprises a sleeve arranged outside the pressurizing fixing needle, a base plate arranged at one end of the sleeve and contacted with the surface of the affected limb, and a spring arranged at the other end of the sleeve.
Furthermore, a locking nut is arranged on the sleeve at one end of the spring, and an external thread section is arranged at the end part of the sleeve corresponding to the locking nut.
Further, the backing plate is the arc, and the backing plate adopts medical silica gel material.
Furthermore, the connecting rods are four, the connecting rods are screw rods, and through holes for the screw rods to penetrate through are formed in the annular positioning plate.
Furthermore, the upper surface and the lower surface of the annular positioning plate are symmetrically provided with locking rings for limiting the plate body, and the locking rings are internal thread rings matched with the screw rods.
The utility model has the advantages that the length of the fixed bracket can be adjusted by at least three annular positioning plate plates with adjustable intervals, and the plate body is effectively fixed by the locking ring; the matched elastic sleeve is arranged outside the pressurizing fixing needle, so that the guide and the protection of the needle body are realized, and the needle body is prevented from loosening; fixed with suffering from limb surface contact through the arc that sets up in the pinpoint department, furthest's laminating skin surface has strengthened the support between annular fixed plate and the suffering from the limb, and under the spring action, can avoid the damage that pressure too big caused.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a front view of the present invention;
fig. 2 is a plan view of the present invention.
In the figure, 1, an annular positioning plate, 2, a pressurizing fixing needle, 3, a connecting rod, 4, a sleeve, 5, a backing plate, 6, a spring, 7, a locking nut and 8, a locking ring are arranged.
Detailed Description
Fig. 1 is the utility model discloses a schematic structural diagram, an external fixation support for orthopedics, insert the fixed needle 2 of pressurization of establishing on annular positioning plate 1 including annular positioning plate 1 and circumference, annular positioning plate 1 is provided with three at least, and annular positioning plate 1 parallel arrangement just through the connecting rod 3 fixed connection that runs through the plate body, inserts and to establish the fixed needle 2 outside correspondences of pressurization on annular positioning plate 1 and be provided with the elastic component that is used for the needle body direction and protection.
During the use, install this outside fixed bolster in suffering from limb department for the elastic component of 1 medial surface of annular locating plate supports suffers from the limb surface, and under the effect of spring 6, possesses certain elasticity, can not harm suffering from the limb because of pressure is too big, and the elastic component has certain direction and guard action to inserting the fixed needle 2 of pressurization of establishing in suffering from the limb, and the elastic component fixed stay is between annular locating plate 1 and suffers from the limb, can strengthen the support intensity of needle body, avoids not hard up and the aversion of needle body.
The connecting rods 3 are four, the connecting rods 3 are screw rods, and through holes for the screw rods to penetrate through are formed in the annular positioning plate 1. Locking rings 8 for limiting plate bodies are symmetrically arranged on the upper surface and the lower surface of the annular positioning plate 1, and the locking rings 8 are internal thread rings matched with the screw rods.
The annular positioning plates 1 can longitudinally move on the connecting rods 3 to adjust the positions, the three annular positioning plates 1 are equally divided according to the length of the affected limb to be fixed, and then the locking rings 8 at the upper end and the lower end of each annular positioning plate 1 are used for limiting and locking the annular positioning plates.
As shown in fig. 2, the elastic member includes a sleeve 4 disposed outside the pressurizing fixing needle 2, a pad 5 disposed at one end of the sleeve 4 to be in contact with the surface of the affected limb, and a spring 6 disposed at the other end of the sleeve 4. Backing plate 5 is the arc, and backing plate 5 adopts medical silica gel material.
The arc backing plate 5 can the laminating suffer from the limb surface and support, adopts the silica gel material, and the texture is softer, can not harm the skin surface, and sleeve pipe 4 activity is worn to establish in the through-hole of seting up on annular positioning plate 1 and is fixed on the ring body through spring 6, and the fixed needle 2 of pressurization is then worn to establish at sleeve pipe 4 center, and sleeve pipe 4's centre bore corresponds fixed needle 2 of pressurization and sets up to the realization is to the location and the protection of needle body.
A locking nut 7 is arranged on the sleeve 4 at one end of the spring 6, and an external thread section is arranged at the end part of the sleeve 4 corresponding to the locking nut 7.
Through the cooperation of lock nut 7 and external screw thread section, inject the flexible degree of cushion 5, adapt to different elastic support demands.
The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
