Description

Quick-assembling rod suitable for Ortho-SUV external fixation frame
Technical Field
The invention belongs to the field of orthopaedics orthopedic rehabilitation, and particularly relates to a quick-mounting rod suitable for an Ortho-SUV external fixing frame.
Background
In the current orthopedics treatment field, the fracture or bone deformity is mostly treated by adopting an internal fixation means of an embedded steel plate steel nail, but in the treatment process, the internal fixation needs to be implanted in an opening of an affected part of a patient, and the operation is possibly required to be carried out for a plurality of times in the treatment process, and the implant is also required to be taken out by the operation again after the operation, so that the internal fixation has the problems of great influence on the patient, more pain in the treatment process, long treatment period, easy infection and the like. With the progress of the orthopedic treatment technology, for some fractures in the orthopedic treatment field, especially for the cases of bone deformity, external fixation is used as an emerging treatment means, the correction range is large, the trauma is small, no secondary surgery is needed, and the like, and the external fixation is used as an alternative scheme for gradually replacing some treatment fields which are difficult to implement by the traditional internal fixation method, the external fixation is fixedly connected with bones through steel needles, fixing rings and fixing bolts, the relative position relationship between the upper fixing ring and the lower fixing ring is adjusted through threaded rods with adjustable length, so that the relative position between the two fixing rings is adjusted, and the treatment process of resetting and correction is realized. One end of the Ortho-SUV external fixation frame serving as a novel external fixation frame is connected to the upper ring through a Hooke hinge, the other three ends of the Ortho-SUV external fixation frame are connected to the lower ring through Hooke hinges, the other sections of the connecting rods are connected to the hinge parts of the adjacent connecting rods, the six connecting rods are connected end to end, the upper ring and the lower ring are fixed by only three nodes, and compared with other external fixation frames, the Ortho-SUV external fixation frame has a wide adjustment angle and flexible adjustment mode. The prior Ortho-SUV external fixation frame changes the relative position relation between two fixed rings by rotating the threaded sleeve, but when the length changes greatly in the installation and adjustment process, the time and the labor are wasted by rotating the threaded sleeve alone. There is a great need for a quick-attach wand for an Ortho-SUV external fixator.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention provides the quick-mounting rod suitable for the Ortho-SUV external fixing frame, and the function of changing the threaded engagement state between the adjusting ring and the screw rod can be quickly realized through the specially designed locking ring and the standard adjusting ring, so that the quick mounting and adjustment of the Ortho-SUV external fixing frame can be realized.
The technical scheme adopted for solving the technical problems is as follows:
the quick-mounting rod comprises a threaded rod, a connecting sliding block, standard rings, a rotary sleeve, locking rings, sleeve fixing rings and fixing sleeves, wherein the threaded rod is connected with an upper ring or a lower ring of the Ortho-SUV external fixing frame through a connecting piece; the rotary sleeve is fixed with the fixed sleeve through a sleeve fixing ring, the fixed sleeve is provided with a buckle, and the buckle is in nested fit with a connecting sliding block on a threaded rod of an adjacent quick-assembly rod.
Further, the connecting sliding block is provided with a clamping groove matched with the clamping buckle on the fixing sleeve, and after the clamping buckle is clamped into the clamping groove, the clamping buckle is fixed in the groove through a pin inserted into the groove to fix the clamping buckle and the connecting sliding block.
Still further, the fixed sleeve lateral wall is opened there is waist type groove, stretches into the threaded rod radial installation locating nut in the fixed sleeve, the locating nut passes waist type groove and can reciprocate in the waist type groove. The positioning nut is used for limiting axial displacement of the threaded rod, and the phenomenon that the threaded rod synchronously rotates when the rotating sleeve is rotated so that the meshing length of the threads cannot be adjusted is avoided.
Still further, the connecting piece includes connecting bolt, universal joint and connection half ear, connection half ear one end fixed mounting is in the tip of threaded rod, the connection half ear other end passes through universal joint and connecting bolt connection, connecting bolt fixes on the mounting hole of the upper ring or the lower ring of Ortho-SUV external fixation frame.
The beneficial effects of the invention are mainly shown in the following steps: the quick installation and adjustment of the Ortho-SUV external fixation frame are realized.

Detailed Description
The invention is further described below with reference to the accompanying drawings.
Referring to fig. 1 to 7, a quick-mounting rod suitable for an Ortho-SUV external fixation frame comprises a connecting bolt 1, a universal joint 3, a connecting half lug 4, a threaded rod 5, a connecting sliding block 6, a standard ring 7, a rotating sleeve 8, a locking ring 9, a sleeve fixing ring 10, a fixing sleeve 11, a buckle 12, a pin 13 and a positioning nut 14;
as shown in fig. 1-3, the Ortho-SUV external fixation frame is composed of an upper ring 2, a lower ring 15 and six newly designed quick-assembly rods, one end of each quick-assembly rod is connected with the upper ring 2 or the lower ring 15 through a universal joint 3, a connecting half lug 4 and a connecting bolt 1, three fixing points are respectively arranged up and down, the other end of each quick-assembly rod is embedded into a connecting sliding block 6 on a threaded rod 5 of an adjacent quick-assembly rod through a buckle 12 designed on a fixed sleeve 11, a clamping groove matched with the buckle 12 on the fixed sleeve 11 is designed on the connecting sliding block 6, after the buckle 12 is clamped into the clamping groove, the buckle 12 is fixed in the groove through a pin 13 inserted into the groove to fix the buckle 12 and the connecting sliding block 6, and thus the six connecting rods are connected end to end, so that the main body is built.
