CN2315907Y - Human canal deroppilation apparatus - Google Patents

Abstract

The utility model relates to the manufacture field of medical equipment. A human canal dredging apparatus is mainly characterized in that the human canal dredging apparatus is composed of a guide pipe, a metal soft rod having a thinner diameter than that of the guide pipe and having a spiral groove, a drill bit, a miniature motor and a rotating shaft of the miniature motor. The utility model can dredge human canals, such as cardiovascular systems, tracheas, food meatus, rectal tubes, etc., without carrying out operations to clean blocking articles and discharge the blocking articles outside bodies. Compared with the present heart bridging, artificial blood vessel putting and tracheas cutting and phlegm discharging operations, the utility model has small cut, less bleeding and low cost, and compared with an inserted explosion method, the utility model avoids hidden dangers that vascular walls are thickened, the elasticity of vascular walls is reduced, etc.

Description

Human pipeline's dredge

This utility model relates to medical apparatus and instruments and makes the field.

The pipeline of human body is a lot, and cardiovascular, trachea, food meatus, bile duct, urethra tube, rectal tube etc. are arranged.When sick, cardiovascular can be blocked by foreign material such as fat granule, clots, myocardial infarction occurs.Trachea can be blocked by thick sputum, and patient is suppressed must be dead.Bile duct can be stopped up by calculus.Urethra top bladder also calculus can occur.Constipation can be blocked rectal tube and anus.The food meatus below is blocked by cancerous protuberance sometimes.

Treat this various obstructions, see at present, what get along with most is that the treatment coronary artery stops up.Its method has out breast to do heart pass, artificial blood vessel is installed, usefulness " intervention explosion method " etc.Yet people know that doing heart pass and artificial blood vessel is major operation.Huge medical expense, common people do not afford to do.And the time of performing an operation is long, often will good several hrs or tens hours, just can finish.Patient's anesthesia duration is long, and wound is big, and it is many to bleed, and post-operative recovery is slow.As for the intervention method, be to insert from femoral artery with conduit, arrive coronary artery along the abdomen thorax artery, adopt " blast " method, make the balloon expansion of conduit head end, thereby being extruded into blood vessel wall, the foreign material of artery-clogging get on.The dredging vascellum ratio is opened breast and done heart pass and artificial blood vessel is installed advantage is arranged like this: wound is little, and it is few to bleed, and operating time is short.But shortcoming is also arranged, and promptly foreign material can not excrete, and accumulate on the blood vessel wall, have increased the thickness of blood vessel wall, have reduced the elasticity of blood vessel wall, have stayed hidden danger to patient.

Treatment trachea thick sputum stops up, and often adopts the way of tracheostomize at present, and the misery that brings patient is bigger.The method of treatment constipation mainly is to adopt coloclysis at present, injects lubricant, and severe patient is difficult to prove effective.Treatment bladder and Biliary Calculi, the cancerous protuberance of food meatus is stopped up, and mainly is at present to adopt to operate on operative treatment.

The purpose of this utility model at first is at cardiovascular, is exactly on the basis of " intervention method ", overcome the shortcoming of " intervention method ", smash with drill bit and stop up foreign material coronarius, and carry by the motion and the conduit of threaded rod, make it to excrete dredging vascellum.Secondly, use this utility model of different size, can also dredge blocked trachea, food meatus, rectal tube etc., make it and to operate on.

Main contents of the present utility model and formation are: one, conduit that can insert human pipelines such as blood vessel, trachea; Two, metal that spiral lamination arranged soft bar slightly thinner than conduit; Three, be contained in the metal bit of the soft rod head end of metal.Drill bit is formed by two, three or four blade angle mounts.The tip angle that blade constitutes has three kinds of forms to select: pure dihedral, middle shape, acute angle shape.Promptly the drill bit at 90 ° of right angles is the most suitable with middle type.Each blade extends to 3/5 place, and turnover backward, and is approaching with conduit.Four, the length of threaded rod surpasses conduit, so its tail end exposes outside the conduit.The section of tail end according to the difference of micro machine turning cylinder eyelet shape, can be designed to that square, prolate are square, pentagon or hexagon.Five, this utility model need be equipped with a micro machine and the common power that can adjust velocity of rotation.

During use, make the coronary artery bypass operation in this way, need be ready to this utility model apparatus earlier, cut femoral artery one osculum again, drill bit and conduit are inserted, under the shining of X-ray, drill bit and conduit are slowly advanced along the abdomen thorax artery simultaneously, behind the arrival precalculated position, power connection.Drill bit rotates immediately, and tamper is shredded.Mince flows out external along the groove of the soft bar of screw thread along with the rotation of threaded rod.After the cardiovascular mediation, slowly extract out conduit and threaded rod and drill bit external.

Use this utility model mediation trachea, food meatus, rectal tube more convenient.Not be used in and make otch on one's body, directly insert in oral cavity or the anus and get final product.But, used specifications and models should be more much bigger than mediation cardiovascular person.

Advantage of the present utility model is: one, with operate on operation and compare, have wound little, bleed less or do not have wound and do not have and bleed the advantage that operating time is short, expense is low, efficient is high.When two, the treatment cardiovascular stops up, can overcome the difficult problem that " intervention explosion method " can't resolve, foreign material can be got rid of external, and blood vessel wall can thickening, and vessel wall elasticity can not reduce.

The preferred plan that realizes the purpose of this utility model is: according to the fat or thin height of human body and the different needs of parts of body pipeline, designing different size is human pipeline's dredge that the length thickness varies in size.The blade of drill bit is three, and blade is 90 ° of right angles with the angle of folding backward that blade constitutes.Drill bit and threaded rod fuse.The thickness of threaded rod is suitable for rotating in conduit.Drill bit exposes outside the conduit, is convenient to bore broken tamper.The tail end of threaded rod also exposes outside the conduit, and the shape of its length and transverse section is convenient to inject in the rotating shaft that micro machine drives, and looks rotating shaft eyelet shape difference, and its profile is four directions, prolate side, pentagon or hexagon.
