Abstract
The utility model discloses a universal connecting screw rod device which is provided with a universal permanent seat, a bolt sliding block connected onto the universal permanent seat and a control bolt for controlling the bolt sliding block to vertically slide, wherein a universal head limiting block matched with the bolt sliding block is arranged on the universal permanent seat; and the two ends of the universal head limiting block are rotationally connected with a universal connector component. The universal connecting screw rod device is structurally characterized in that the two ends of the universal connecting screw rod device can be adjusted within the maximal scope of 45 degrees in the peripheral direction and are fixed and loosened, the structure is simple, and the adjustment is convenient, and the treatment of different types of fractures is adapted to achieve a best treatment scheme that a skeleton is strongly fixed at the early stage, and a joint safely moves at the later stage.
Description
Technical field
This utility model relates to a kind of for surgical medical equipment, particularly a kind of a kind of universal connecting screw rod device for Orthopaedic external fixator.
Background technology
After fracture, need to be fixed skeleton, help it to recover as soon as possible and heal, Orthopaedic external fixator is one of medical apparatus and instruments of commonly using on the Orthopedic Clinical.Existing Orthopaedic external fixator, its basic structure comprise support bar and the polylith fixture block that is connected the support bar connection, have been bolted the draw point fixture block on the fixture block.After the skeleton of fracture site both sides penetrated draw point, with the draw point fixture block draw point is fixed.Although said structure is easy to use, angle of regulation range is little, uses dumbly, can not adapt to the treatment of dissimilar fracture, and is strong fixing to reach early stage, the therapeutic regimen of later stage joint security activity.
The utility model content
The purpose of this utility model is the problem that solves above-mentioned existence, provide a kind of realization enlarge range of accommodation simultaneously more enough flexibly fixing with unclamp, adapt to a kind of universal connecting screw rod device of the treatment of dissimilar fracture.
The purpose of this utility model realizes as follows: a kind of universal connecting screw rod device, have Universal fixing seat, be connected to the bolt slide block on the described Universal fixing seat, and the control bolt that slides up and down of control bolt slide block, described Universal fixing seat is provided with the Universal-head confinement block that cooperates with the bolt slide block, and described Universal-head confinement block two ends and universal joint assembly are rotationally connected.
Further, the universal joint assembly comprises and is positioned on the same level line two groups of screw rod universal joints and screw rod that described screw rod universal joint is arranged on screw rod on the Universal fixing seat by pin.
Further, described bolt slide block two ends are connected with described Universal-head confinement block wedge-like engagement.
Advantage of the present utility model: this utility model is mainly used in External fixation palm or phalanx fracture, its architectural feature realization two ends circumferentially maximum 45 ° of range regulation are also fixed and are unclamped, treatment simple in structure, easy to adjust, as to adapt to dissimilar fracture, strong fixing to reach early stage, the therapeutic regimen of later stage joint security activity.
Description of drawings
Content of the present utility model is easier to be expressly understood in order to make, and the below is described in further detail this utility model, wherein according to specific embodiment also by reference to the accompanying drawings
Fig. 1 is structural representation of the present utility model;
Reference numeral: 1, Universal fixing seat, 2, the bolt slide block, 3, the control bolt, 4, the Universal-head confinement block, 5, the universal joint assembly, 51, the screw rod universal joint, 52, screw rod, 53, pin.
The specific embodiment:
As shown in Figure 1, a kind of universal connecting screw rod device, have Universal fixing seat 1, be connected to the bolt slide block 2 on the described Universal fixing seat 1, and the control bolt 3 that slides up and down of control bolt slide block 2, described Universal fixing seat 1 is provided with the Universal-head confinement block 4 that cooperates with bolt slide block 2, and described Universal-head confinement block 4 two ends and universal joint assembly 5 are rotationally connected; Described universal joint assembly 5 comprises and is positioned on the same level line two groups of screw rod universal joints 51 and screw rod 52 that described screw rod universal joint 51 is arranged on screw rod 52 on the Universal fixing seat 1 by pin 53; Described bolt slide block 2 two ends are connected with described Universal-head confinement block 4 wedge-like engagement.
Its work process is: screw rod 52 is connected as a single entity screw rod 52 and screw rod universal joint by pin 53, and its maximum on Universal fixing seat 1 can reach circumferential 45 ° range of activity; Control bolt 3 moves up part bolt slide block 2 when turning clockwise, this moment is by the wedge-like engagement of bolt slide block 2 two ends and Universal-head confinement block 4, so that Universal-head confinement block 4 moves to two ends and clamping screw universal joint 51, make itself and Universal fixing seat 1 firm interlock, thereby reach fixation; When being rotated counterclockwise control bolt 3 part bolt slide block 2 is moved down, bolt slide block 2, Universal-head confinement block 4, screw rod universal joint 51 are in releasing orientation between the Universal fixing seat 1, thereby reach free activity purpose at this moment.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is specific embodiment of the utility model; be not limited to this utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
