The memory alloy stent for the orifices of the five sense organs of the human body has the advantages that the stent body can be firmly positioned without sliding easily, the memory alloy stent is excellent in biocompatibility, high in corrosion resistance, simple in processing technology and convenient to clinically operate, has a unique continuous self-pressurization function and has an excellent application prospect in the aspect of treatment for patients suffering from nasosinusitis and lacrimal duct obstruction.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, be specifically related to a kind of memorial alloy face orifice bracket.
Background technology
At present, along with the rising of sinusitis sickness rate, its Therapeutic Method development.The Drug therapy initial stage of taking medicine can to a certain degree relief of symptoms, but effect is slow, and Long-term taking medicine easily causes the metabolic disturbance of patient's body, reduces immunity, even causes other complication.Operative treatment, due to surgery of nasal cavity limited view, is difficult to accurately locate focus, is thus easy to recurrence, brings very large stress and heavy financial burden to patient.Although micro-wave therapeutic is more advanced, because just surface is dispelled, thorough radical cure cannot be reached, be easy to recurrence equally.Sacculus treatment is through after a period of time, and the symptom that Dou Kou is again narrow appears in some patients, and the drain affecting hole chamber causes pathological changes to recur, and affects operative effect, thus needs to carry out second operation.Meanwhile, for avoiding occurring above-mentioned symptom, needing patient repeatedly to check, not only can increase iatrogenic creation, and increase the misery of patient.The patent No. is nasal sinuses support and dedicated transport instrument thereof disclosed in 201110460985.2, the postoperative use seal wire of nasal sinuses balloon expandable is utilized to find Dou Kou position, by coordinating of flexible inner tube and flexible jacket, under the control of joystick, nasal sinuses support is delivered to Dou Kou place, and move by sliding handle control flexible jacket thus discharge nasal sinuses support, nasal sinuses support is expanded naturally and presses close to Dou Koubi, thus complete the expansion of Dou Kou is supported.Use this nasal sinuses support can make the time lengthening that Dou Kou is again narrow.But support that this invention uses is the establishment of silk material, and processing technique is complicated, and not easily take out after expansion support.
Obstructed lacrimal passage is the modal class disease of ophthalmology, main manifestations is that eyes are shed tears, suppurate in large canthus, local redness, ache influence vision etc. can be there is in part, at present, the methods such as non-operative treatment and lachrymal sac excising operation, Dacryocystorhinostomy and laser such as spy is logical, intubate, threading, high-frequency electrical are mainly contained when treating obstructed lacrimal passage.Wherein, adopt laser in treating lacrimal duct obstruction can reduce the tissue injury of patient to a certain extent, do not destroy normal lacrimal passage structure simultaneously.But these methods all can not provide lasting treatment, thoroughly obstructed lacrimal passage cannot be effected a radical cure.
Summary of the invention
The object of the invention is to for prior art Problems existing, a kind of memorial alloy face orifice bracket is provided, this support can not only expand sufferer place block tract, play support and the effect of drain, and implant conveniently, easily take out after drain secretions, be particularly useful for nasal sinuses and obstructed lacrimal passage treatment.
For this reason, the present invention adopts following technical scheme:
A kind of memorial alloy face orifice bracket, comprise one by Memory Alloy metal coiled sheet around the cylindric support body formed, the diameter of described support body is reduced to centre gradually by two ends, and the two ends of support body are toroidal, the mid portion of support body forms support portion, formation location division, two ends, and support body side opening is provided with through hole.
Further, the Surface coating of described support body has the thin film be made up of the medical macromolecular materials that biocompatibility is good.
Further, described medical macromolecular materials are politef, polyester textile or medical grade silicon rubber.
Further, the cross section of described support body is in " C " type, " O " type or " e " type.
Further, the two ends of described support body are provided with outwardly lug.
Further, described through hole is strip.
The memory performance that the present invention utilizes memorial alloy excellent and elastic performance also design according to the dissection of human body nasal cavity and lacrimal passage etc., physiology and biomechanics characteristic, can expand voluntarily under body temperature after the support body that memorial alloy is made implants sufferer position.The little structure in large centre, support body two is moved at Dou Kou or lacrimal passage place after can effectively preventing support body from implanting, and can accomplish to fixedly positioning after the location division expansion of bell mouth shape.Being designed with of through hole is beneficial to reduces frame structure intensity, makes support body easily moulding, namely easy according to variations in temperature expansion or reduce.
To sum up, beneficial effect of the present invention is: support body firm position, not easily occur sliding, and there is the lasting self-pressurization function of good biocompatibility, stronger corrosion resistance and uniqueness, and processing technique is simple, clinical manipulation is convenient, has a good application prospect in sinusitis and obstructed lacrimal passage treatment.
