The device comprises at least one pair of fixers and fixing sheets (20), wherein, each fixer (10) is provided with a pull rod (11), at least one group of fixing claws and a locking component (12); the fixing claws are hinged at the lower end of the pull rod (11) and can embrace the rib; the locking component (12) is arranged on the pull rod (11) and acts on the fixing claws; and the fixing sheets (20) are arranged at the upper end of the pull rod (11), and are in detachable connection with each fixer (10). The utility model has the advantages of simple operation, reliable fixing and wide application range; the minimally invasive surgery can be realized, and the secondary surgery is not needed, which is favorable for patients to recover; and the surgery condition requirement is not high, so the utility model is convenient for popularization.

Description

The fracture of rib reseting fixture

Technical field

This utility model relates to bone surgery set, particularly a kind ofly is used for the fixture that fracture of rib resets.

Background technology

The traditional therapy of fracture of rib has following two kinds, and first kind is to paste external fixation with wide adhesive plaster stacked tile type, and this method fracture can not active homing and fixing, the later stage malunion, and intercostal nerves pain is obvious; Second kind is operation traction and fixation and open reduction, traction and fixation needs long-term bed, the patient is prone to complication, the open reduction long incision, dissection scope is wide, and damage is big, most second operations that need take out immobilization material, if do not take out, then also retain foreign body in the body for a long time, influence patients ' life quality and medical check once more.Be reported in the auxiliary rib nail internal fixation of fracture that can absorb down of thoracoscope, Wicresoft is respond well, but long-term effect does not still have final conclusion, and restricted by equipment, and inconvenience is universal.

The utility model content

Technical problem to be solved in the utility model provides a kind of fracture of rib reseting fixture, and this device is reliable not as good as simple to operate, fixing, and can realize Minimally Invasive Surgery.

The technical scheme that its technical problem that solves this utility model adopts is: fracture of rib reseting fixture of the present utility model, it is characterized in that it comprises: at least one pair of holder, but holder has pull bar and be articulated in the fixed claw of at least one group of obvolvent rib of its lower end, and is installed on the pull bar and acts on locking member on the fixed claw; Stator removably connects at upper end and each holder of pull bar.

The beneficial effects of the utility model are, and are simple to operate, fixing reliable, applied widely; Can realize Minimally Invasive Surgery, and not need second operation, help rehabilitation of patients; Surgical condition is less demanding, is convenient to penetration and promotion.

The specific embodiment

Below in conjunction with drawings and Examples this utility model is further specified.

With reference to Fig. 1, fracture of rib reseting fixture of the present utility model comprises: at least one pair of holder 10, but holder 10 has pull bar 11 and is articulated in the fixed claw of at least one group of obvolvent rib of its lower end, and is installed on the pull bar 11 and acts on locking member 12 on the fixed claw; Stator 20 removably connects at upper end and each holder 10 of pull bar 11.With reference to Fig. 5 and Fig. 6, when implementing fracture of rib reduced operation, respectively install and fix a holder 10 in rib fracture location both sides, by stator 20 two holders 10 are connected to form one again, it is fixing to finish resetting of fracture of rib.If occur two places or multiple fracture on the root bone, then on each section rib, install and fix a holder 10 as the case may be respectively, by a stator 20 each holder 10 is connected to form one, it is fixing to finish resetting of rib multiple fracture again.This shows, the utlity model has reliable and advantage of wide range of application simple to operate, fixing, and can realize Minimally Invasive Surgery, do not need second operation, help rehabilitation of patients, surgical condition is less demanding, is convenient to penetration and promotion.

The effect of locking member 12 is that holder 10 is securely fixed on the rib.Shown in Fig. 1 is a kind of the simplest structure, the i.e. sleeve of locking member 12 for being threaded with pull bar 11.During reattachment surgery,, upwards spur pull bar 11 and make the fixed claw obvolvent on rib when fixed claw is stretched in the human body by the micro-incision outside the rib both lateral sides respectively, turnbarrel again, the sleeve lower port pushes against and is about to holder 10 behind the fixed claw and is securely fixed on the rib.

With reference to Fig. 1, fixed claw is installed on the bearing pin 15 that is fixedly set in pull bar 11 lower ends, and on a holder 10, the quantity of fixed claw is two or many.In by the embodiment shown in Fig. 2, described fixed claw comprises right fixed claw 13 and the left fixed claw 14 that is installed at interval on the bearing pin 15.In by another embodiment shown in Fig. 3, described fixed claw comprises a right fixed claw 13 and two left fixed claw 14a, the 14b that are installed at interval on the bearing pin 15, and right fixed claw 13 is between two left fixed claw 14a, 14b.

With reference to Fig. 4, offer vertical groove 21 on the described stator 20, the upper end of pull bar 11 is passed vertical groove 21 backs and by nut stator 20 is fixed on the pull bar 11.Vertically groove 21 offers the different spacing that also makes stator 20 can adapt to 10 of each holders well.Stator 20 can adopt rustless steel etc. to have certain rigidity and flexible material, and crooked radian is consistent with the physiological bending radian of rib during use.

Some principles of the above this utility model fracture of rib reseting fixture that just explains through diagrams, be not be this utility model to be confined to shown in and in described concrete structure and the scope of application, so every the corresponding modify and equivalent that might be utilized all belongs to the claim that this utility model is applied for.
