Abstract
A rehabilitation fixing ring for patellar fracture is composed of a fixing ring, fixing screws, fixing hooks and a connecting slide rail. The fixing ring is a main body supporting part, is divided into two parts, and is composed of two semi-circle rings. The connecting slide rail is arranged between the two semi-circle rings, and at least two parallel fixing screws should be arranged in the fixing ring. The fixing hooks for clamping edges of patella are arranged on two ends of the fixing screws. Nuts for adjusting positions of the fixing hooks and positioning the fixing hooks are arranged on the basal parts of the fixing hooks. The rehabilitation fixing ring for patellar fracture can adjust the size of the fixing ring at any time according to conditions of patients, has convenient use, does not affect the use of an instrument for observing conditions of fracture parts at any time when in use, can apply cohesion force to fracture ends continuously when in use, can be adjusted arbitrarily, can correct fixing deviation in time for keeping fixing force constant relatively, carries out fracture healing and function exercise of knee joints synchronously, and is applicable to patellar fractures of all categories.
Description
Technical field:
This utility model relates to the auxiliary implement of bone injury operation, relates in particular to Patella fracture rehabilitation ring for fixing.
Background technology:
Using bone external fixator treatment Patella fracture method comparatively commonly used at present, is the two pairs of arc loopers of periphery insertion from patella, to the center pressurization, epiphysis is drawn close.But pressure is not enough, and in early days in the activity by the active force of quadriceps femoris and articulatio femoropatellaris, easily rotate displacement forward.The arc looper maintains static up and down, and fixed position is on the cephalolateral margin of the utmost point up and down, can not be arbitrarily with the folded block adjustment with in time correct droop, especially to utmost point avulsion folding down, utmost point comminuted fracture can't be used down, has limited its scope of application.Although a kind of patella fixator of all-metal plate is also arranged, first because the effect of blocking of metallic plate has influenced the normal observation of using instrument, second the actual inconsistent problem of unified stress point can not in full accordly take place in the stress owing to fixing point.Chinese patent 200320107354.3 discloses a kind of Patella fracture rehabilitation ring for fixing, has overcome above-mentioned defective substantially, but because circle body is an overall structure, can't adjust at any time as required, causes and uses inconvenience.
The utility model content:
The purpose of this utility model is, overcomes the deficiencies in the prior art part, and a kind of easy to operate, fixed, wide Patella fracture rehabilitation ring for fixing that also can carry out the size adjustment according to patient's situation at any time of the scope of application is provided.
Patella fracture described in the utility model rehabilitation ring for fixing includes ring for fixing, standing screw, fixation hook and is connected slide rail and forms.Said ring for fixing is the body supports part of Patella fracture described in the utility model with the rehabilitation ring for fixing, and said ring for fixing is divided into two parts, is made up of two semicircular ring.Between said two semicircular ring, be provided with the connection slide rail, semicircular ring be connected slide rail and fix with setscrew nut.Two parallel standing screws should be set in ring for fixing at least, and according to the different requirements of purposes, it also is feasible that three standing screws are set certainly.At the two ends of standing screw, be provided with the fixation hook that is used to block the patella edge.The basilar part of fixation hook also is on standing screw, is provided with to be used to make fixation hook to adjust position and localized nut.During use, at first fixation hook is blocked the last lower limb of patella, adjust the nut that is arranged on the fixation hook outer rim, reset and the chucking that pressurizes, impel its healing until patella with fracture.Said standing screw, cross section are " D " shape, can satisfy fixation hook and move axially and do not rotate along standing screw, can satisfy the adjustment and the positioning and fixing of screw flight again.
Patella fracture described in the utility model rehabilitation ring for fixing is a bracing frame with the ring for fixing, implements location to the fracture patella with standing screw and fixation hook, and fixed, difficult drop-off has the characteristics that fixing point is many, pressure is little simultaneously.Patella fracture described in the utility model belongs to external fixer with the rehabilitation ring for fixing, and can regulate the ring for fixing size at any time according to patient's situation.Shou Shu wound face is little comparatively speaking, easy to use, do not influence the situation of using the observation of use instrument fracture site at any time in the use, apply cohesion to fracture end sustainably during use,, adjust arbitrarily according to the position of bone piece, in time correct droop, to be maintained fixed the constant relatively of power, union of fracture and kneed functional exercise can be carried out synchronously, be applicable to all types of Patella fracturies.
Description of drawings:
Accompanying drawing is the structural representation of Patella fracture described in the utility model with the rehabilitation ring for fixing.1-ring for fixing 2-standing screw 3-fixation hook 4-connects slide rail
The specific embodiment:
Referring now to accompanying drawing, be described as follows in conjunction with the embodiments: Patella fracture described in the utility model rehabilitation ring for fixing includes ring for fixing 1, standing screw 2, fixation hook 3 and is connected slide rail 4 and forms.Said ring for fixing 1 is the body supports part of Patella fracture described in the utility model with the rehabilitation ring for fixing, and said ring for fixing 1 is divided into two parts, is made up of two semicircular ring.Between said two semicircular ring, be provided with and connect slide rail 4, semicircular ring be connected slide rail 4 and fix with setscrew nut.Two parallel standing screws 2 should be set in ring for fixing 1 at least, and according to the different requirements of purposes, it also is feasible that three standing screws 2 are set certainly.At the two ends of standing screw 2, be provided with the fixation hook 3 that is used to block the patella edge.The basilar part of fixation hook 3 also is on standing screw 2, is provided with to be used to make fixation hook 3 to adjust position and localized nut.During use, at first fixation hook 3 is blocked the last lower limb of patella, adjust the nut that is arranged on fixation hook 3 outer rims, reset and the chucking that pressurizes, impel its healing until patella with fracture.Said standing screw 2, cross section are " D " shape, can satisfy fixation hook 3 and move axially and do not rotate along standing screw 2, can satisfy the adjustment and the positioning and fixing of screw flight again.Patella fracture described in the utility model rehabilitation ring for fixing is a bracing frame with ring for fixing 1, and with the location that standing screw 2 and fixation hook 3 are implemented the fracture patella, fixed, difficult drop-off has the characteristics that fixing point is many, pressure is little simultaneously.Do not influence the situation of using the observation of use instrument fracture site at any time in the use, apply cohesion to fracture end sustainably during use, position according to the bone piece, adjust arbitrarily, in time correct droop, to be maintained fixed the constant relatively of power, union of fracture and kneed functional exercise can be carried out synchronously, be applicable to all types of Patella fracturies.
