Abstract
A dragline pressurization empty sleeve for patella fracture is characterized by comprising an empty sleeve. The empty sleeve comprises a straight empty drum, an enlarged drum cap is fixedly arranged at one end of the straight empty drum, and an outer sleeve head is sleeved at the other end of the straight empty drum. The outer sleeve head can be pulled out and plugged in and sleeved outside the straight empty drum in sliding mode. An enlarged cap head is fixedly arranged at an outer end of the outer sleeve head in corresponding mode. The utility model further provides a pressurization fixing device for the patella fracture. The pressurization fixing device comprises two empty sleeves penetrating through two sides of a central vertical line of a fixed patella at intervals in approximately parallel mode and a twisting tensioning pressurization pull cable matched with the empty sleeves and used for fixing the patella. The straight empty drum and the outer sleeve head move towards each other through twisting and tensioning of the pressurization pull cable, so that pressurization and tensioning effects are caused on a patella fracture surface. The pressurization fixing device prevents two fracture ends from separating and shifting in a side direction, prevents the patella from deforming, maintains fracture stability, and is simple in structure, practical, convenient to operate, good in working stability and favorable for fracture healing.
Description
Technical field
This utility model relates to the instrument field that is implanted into of orthopaedic trauma fracture internal fixation, is meant pressurize empty jacket casing and use the pressurize Patella fracture pressurization fixture of empty jacket casing of this drag-line of the drag-line that is used for Patella fracture specifically.
Background technology
Patella fracture is one of common type that produces behind the exogenous injury of human body fracture, is the commonly encountered diseases of orthopaedic trauma.Generally need open reduction after the Patella fracture displacement, the anatomical reduction of trying one's best, effective internal fixation, early functional exercise could at utmost recover its function of joint.Can not reach above-mentioned treatment requirement, be easy to generate traumatic gonarthritis, patellofemoral arthritis, complication such as knee stiffness have a strong impact on patient's work capacity, and it is disabled to leave over work in various degree.
Open reduction is dissected para-position as far as possible, mainly relies on the experience and the technical merit of surgical doctor, and effective internal fixation, early functional exercise is more prone to good internal fixation apparatus.Current each hospital uses the equipment of Patella fracture internal fixation to have wire binding to fix, and Kirschner wire pierces fixing, and Kirschner wire adds tension band wire and D; Screw fixings; Screw adds tension band wire and D etc., and its deficiency is that draw point moves easily, possibly be out of shape after needle body is stressed; Stability is not good, influences therapeutic effect.
The utility model content
The purpose of this utility model is the deficiency that overcomes prior art, and pressurize empty jacket casing and use the pressurize pressurization fixture of empty jacket casing of this drag-line of a kind of drag-line that is used for Patella fracture is provided, and is simple and practical; Easy to operate; Constant intensity is big, and side effect is little, and therapeutic effect is stable.
The technical scheme of this utility model is following:
The drag-line that the is used for Patella fracture empty jacket casing that pressurizes, it is characterized in that: comprise the sky jacket casing, this sky jacket casing comprises the straight empty tube that is provided with axial central through hole, tube medicated cap, the other end that end of this straight empty tube is installed with expansion are arranged with outer pullover; But outside the straight empty tube that is slidingly located in to outer pullover plug; Said outer pullover external end head correspondence is installed with the medicated cap head of expansion.
Above-mentioned straight empty tube, outer pullover outer face are curved end and are evenly equipped with the detent of many radial arrangement.
A kind of empty tube drag-line pressurization fixture that is used for Patella fracture is characterized in that: comprise that parallel interval is placed through the two above-mentioned empty jacket casings of the vertical line both sides, patella center that are fixed and the drag-line that pressurizes substantially; Said pressurization drag-line comprises that one is 8 fonts and is arranged in the pressurization drag-line between the two empty jacket casings, and the X word cross part card of 8 fonts pressurization drag-line is pressed on the patella front surface; This 8 font pressurization drag-line is provided with the pressurization kink respectively in each port part of two empty jacket casings.
The outer pullover homonymy of above-mentioned two empty jacket casings is arranged; The kink of said 8 fonts pressurization drag-line all is positioned at outer pullover port.
Can know that by above description compare with prior art, the beneficial effect of this utility model is:
One, this utility model adopts the pressurization drag-line to cooperate the straight empty tube of the fit that can slide relatively, the empty jacket casing of outer pullover formation; Empty jacket casing is set in the preset patella tunnel; The pressurization of utilization kink drag-line is fastening to impel straight empty tube, outer pullover moving axially relatively, and makes a medicated cap, medicated cap head to patella the two poles of the earth (two ends) generation pressurization, guarantees that the Patella fracture face closely is pressed against together; The pressurization drag-line is to play the tensioning of kink mode; It is effective to pressurize, and the pressurization drag-line displacement can not take place gets loose good operating stability.
Two, realize strong internal fixation; Prevent to fracture lateral displacement with separate; There is sufficient intensity to keep to reset the stable of back fracture, because patella thickness is at 21-26mm, average (23.39 ± 1.19mm); Can design outer sleeve at 3.5-4.5mm; The Kirschner wire of the 2-2.5 diameter that uses than present clinician is fixing thick, stretches and bends active shearing force so this enough holder of diameter can effectively resist load that the knee joint activity produces and patient, thereby reach effective reliable internal fixation effect.Through the pressurization drag-line to the fracture over glaze to pressurization, effectively resist the tension force of quadriceps femoris, patellar ligament, prevent the shift separation of fracturing, cause the fracture interface closely to contact, further strengthen the stability after the reduction of the fracture, promote union of fracture.
Three, this utility model knee joint activity is as early as possible taken exercise, and reduces joint stiffness, improves the normal activity degree and the arthritic generation of minimizing traumatic bone property in joint, at utmost obtains the recovery of knee joint function, reduces disability rate, improves work capacity.
Four; Use this holder treatment Patella fracture, holder and patella bone surface closely paste volt together, have overcome internal fixation such as Kirschner wire and have caused that the pin end significantly exposes bone surface, rotates; Bring the secondary damage of medical treatment, prick skin, damage flesh key, influence joint motion exercise etc.
