Description
Technical field
This utility model relates to medical instruments field, more particularly, relates to a kind of Medical self-locking formula titanium silk stitching thread.
Background technology
In orthopaedics and thoracic surgery clinical treatment, usually need to fix with steel wire bone, bone cips and the artificial prosthesis of fracture, sew up the breastbone of fixedly riving with steel wire in the thoracic surgery operation on heart.At present, that uses clinically mostly is the rustless steel steel wire, after sewing up with pliers by manual operation taut wire then terminal mutually strand cable be screwed in tighten together fixing.Because steel wire is sub-thread, and is generally thinner, excessively loose when tightening, the postoperative steel wire is loosening fixing unreliable; Tension when tightening, steel wire are rolled over rear stress and are weakened the meeting fracture.Simultaneously, penetration power was poor when common three edged needle band pin steel wire passed bone, sew up very effort, and the draw point diameter is generally greater than steel wire diameter, when passing the spongy bone such as breastbone at operation on heart and sewing up, the pinprick oozing of blood is more common, especially when the tension of forming from steel wire, because single steel wire more carefully can be cut surface of bone and be caused secondary damage hemorrhage.The steel wire of tying up when in addition, the surgical patient activity is violent may get loose the displacement fracture.These materials are because be that stainless steel structure contains iron ion simultaneously, biocompatibility is not good enough in human body, local anaphylaxis or inflammation, foreign material repulsion reaction etc. can occur in part patient, need when serious to take out by second operation, increase patient's misery and medical expense burden.And when stainless steel silk existed in the body, ferrous metal had the metal tail shadow when CT examination, affect CT examination, and the MRI inspection that is magnetic of iron ion band can't be done.
Titanium density is low, is 4.5 g/ccs, is about 60% of steel, lightweightly can increase patient comfort sense and movable function.Intensity is high, and specific strength is large, and the intensity level of implant should be higher than natural bone in the surgical operation, and the yield strength of titanium or titanium alloy is 207-1379MPa, and natural bone is 83-117MPa, therefore can satisfy performance requirement.Titanium has advantages of simultaneously that without magnetic heat conductivity is little and linear expansion coefficient is little.Heat conductivity only is 1/5 of steel, 1/3 of aluminum, 1/2 of copper; Linear expansion coefficient is 1/5 of carbon steel, for stainless half.The coordination of elastic modelling quantity between implant and the natural bone, most important for increasing the service life, natural bone must be curved and continuous.The low elastic modulus of bone is about 16.5 * 103MPa, and titanium is cobalt and rustless steel half, i.e. 102.7-113.3 * 103MPa.The elastic modelling quantity of titanium is low, accepts implantation piece for human body extremely important, has reduced simultaneously the additional stress on the combination interface, has prolonged service life.Titanium or titanium alloy has good corrosion resistance, titanium is nontoxic, nonmagnetic, be the good the selection of material of medical apparatus and instruments, at present, titanium or titanium alloy has been widely used in the application in the fields such as joint prosthesis, artificial bone, joint sole, knochenbruch holder, intramedullary pin, Cardiac valve prosthesis, skull.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of easily fixing, mechanical strength is good and the compatibility of people's in-vivo tissue is good Medical self-locking formula titanium silk stitching thread is provided.
In order to address the above problem, this utility model provides a kind of Medical self-locking formula titanium silk stitching thread, comprises stitching thread and sewing needle, and described stitching thread is made of multiply titanium silk, and stitching thread one end is provided with five prismatic sewing needles, and the other end is provided with locking device.
As one preferred, described locking device comprises egative film and tabletting, on the described egative film screw is set, described tabletting passes screw, arranges one and the supporting nut of screw above tabletting.During use, by screwing fixedly stitching thread of nut.
As one preferred, at the contact surface of described egative film and tabletting frosted or band are set, increase sutural fastening to play anti-skidding effect.
As one preferred, on the described egative film aperture is set, the number of described aperture is 2-4.The effect of aperture is can attachment screw locking device to be fixed in displacement does not occur on the bone to get loose.
As one preferred, there is the haemostatic medicament nano coating on described five prismatic sewing needles and titanium silk surface.
The utility model has the advantage of: easy and simple to handle, interior fixation in (1) art, simplify operation technique; (2) structure of multiply titanium silk can satisfy fixing required mechanics requirement in the fracture so that this device has enough mechanical strengths; (3) the locking device hole of tightening up a screw can attachment screw be fixed in and displacement can not occur on the bone be got loose; (4) raw material convenient sources lowers production cost; (5) finished product is convenient to package sterilization, preservation; (6) good in the compatibility of people's in-vivo tissue, and for the impact of CT, MRI inspection nothing, the taking-up of need not again performing the operation.

Label in the diagram is: 1, sewing needle; 2, stitching thread; 3, egative film; 4, tabletting; 5, screw; 6, nut; 7, aperture.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is elaborated, the purposes of embodiment only is to explain the present invention and non-limiting technical scheme.
Embodiment, Medical self-locking formula titanium silk stitching thread
As shown in Figure 1, Medical self-locking formula titanium silk stitching thread comprises stitching thread 2 and sewing needle 1, and stitching thread 2 is made of multiply titanium silk twisted, and every titanium silk has identical elongation at break, and stitching thread 2 one ends are provided with five prismatic sewing needles 1, and the other end is provided with locking device.
Locking device comprises egative film 3 and tabletting 4, and screw 5 is set on the egative film 3, and tabletting 4 passes screw 5, arranges one and the supporting nut 6 of screw 5 above tabletting 4.During use, by screwing fixedly stitching thread of nut 6.
At the contact surface of egative film 3 and tabletting 4 frosted or band (diagram does not draw) are set, increase fastening to stitching thread 2 to play anti-skidding effect.
On the described egative film 3 aperture 7 is set, the number of aperture is 2-4, and aperture is arranged on the screw both sides among Fig. 1, also can aperture evenly be set around screw on egative film, such as arranging 4.The effect of aperture is can attachment screw locking device to be fixed in displacement does not occur on the bone to get loose.
There is the haemostatic medicament nano coating on five prismatic sewing needles 1 and titanium silk surface.The titanium alloy that the whole material of locking device adopts orthopedic steel plate to use, 2 centimetres of length, 0.4 centimetre of width, thickness are the thickness of common iron plate.
During use, after sewing needle 1 stitching is complete, cut off sewing needle 1, stitching thread 2 passes locking device, so that stitching thread 2 places tabletting 4 belows, step up continuous curling the reaching of the broken ends of fractured bone with the general surgery needle holder and tighten up, block being locked with needle holder or common wrench fastening nut 6; Perhaps stitching thread 2 passes and beats an outstanding knot behind the locking device and be not shifted to block, and fastening nut 6 blocks and is locked again.Several apertures on the locking device can be used for installing screw and are fixed on the bone structures such as bone cips.
The above only is preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from this utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
