Abstract
The utility model relates to the development and the application of an artificial salivary gland catheter which is mainly used for preventing catheter narrowing from occurring and reconstructing a catheter after salivary gland catheter surgery. The artificial salivary gland catheter is characterized in that the inner diameters of two ends of the catheter are equal, and the outer diameters of two ends of the catheter increase gradually. The outer diameter of the front end of the catheter is 0.1mm smaller than the outer diameter of the rear end of the catheter. The artificial salivary gland catheter has the advantages that the catheter wall is thin and is around 0.2mm, the catheter diameter is large and is around 0.6mm, and the artificial salivary gland catheter is closer to a normal salivary gland catheter in anatomy, and is beneficial to maintaining the smoothness of the catheter and preventing the catheter narrowing from occurring. The artificial salivary gland catheter well solves complications of closing adhesion and narrowing after the salivary gland catheter surgery, and can effectively prevent the postoperative recurrence of the salivary gland catheter surgery. The artificial salivary gland catheter further has the advantages of being simple in operation, convenient to use, low in manufacturing cost and the like, and can be widely applied to clinic.
Description
Technical field
This patent relates to a kind of artificial saliva gland conduit, is applicable to the expansion of salivary gland conduit behind the Oral and Maxillofacial Surgery operation on salivary gland and reproduces, and belongs to technical field of medical instruments.
Background technology
Chronic obstructive parotitis is the common disease that betides the parotid gland, is by various local causes, goes out to be obstructed as calculus, foreign body, the parotid secretion liquid stream that causes such as narrow.Clinical swelling repeatedly, pain and the conduit mouth that mainly shows as parotid gland body of gland suppurated, and be often relevant with feed.Radiography and pathology mainly show as the inflammatory lesion of main pipe and brasnch conduct.Compare with the parotitic diagnostic method of traditional chronic obstructive, the salivary gland scope is having superiority aspect the etiological diagnosis of parotid duct obstruction, many reasons that cause the conduit internal congestion are just found after the salivary gland scope occurs, as fiber-like material, polyp, mucus embolus etc. in the conduit.Normal parotid duct endoscopic image characteristics are that pipe inner wall is smooth glittering, only have minute blood vessel to distribute, and in the parotitic conduit of chronic obstructive, can find pipe inner wall mucous hyperemia, hemorrhage, hypertrophy and mucus embolus, calculus etc. under the scope.
The Therapeutic Method that chronic recurrent parotitis is traditional comprises parotid duct ligation, tympanic nerve excision, gentian violet injection, the excision of parotid gland gland leaf etc.But the shortcoming of above method is to damage greatlyyer, and has lost the normal physiological function of the parotid gland.Along with the development of salivary gland mirror technology, chronic obstructive parotitis or parotid duct calculus more and more adopt therapeutic endoscopy at present, and its advantage is that damage is little, and the physiological function of the parotid gland is restored.But its shortcoming is to cause damage, the hyperemia of pipe inner wall, postoperative that narrow, the adhesion of the narrow or salivary gland conduit mouth of the Secondary cases of conduit may take place in the process for the treatment of.And because the existence of mucus embolus is easy to block again, the inflammatory material in the conduit is discharged smoothly, therapeutic effect is not good enough.Therefore need the implantable artificial conduit to keep the unobstructed of salivary gland conduit.
For the treatment of lithiasis of submaxillary gland duct, if calculus is positioned at the conduit leading portion, after then directly stone is got in incision, catheter wall and mucous membrane of floor of mouth can be sewed up at present.If calculus is positioned at the dark face of conduit, with the intersection of body of gland, get to need behind the stone catheter wall sewed up and close, be easy to cause the duct wall adhesion narrow like this, postoperative swelling.Adopt the method to treat the patient of some submaxillary gland deep branch catheter calculus, it is obvious that the postoperative ubiquity under the jaw swelling pain, and catheter lumen is narrow, the problem of locking.Therefore also need the implantable artificial conduit to keep the unobstructed of salivary gland conduit.
Have report to adopt catheter holder to keep the unobstructed of conduit abroad, obtained good effect, but weak point is the price comparison costliness, each support approximately needs the tens thousand of units of RMB, does not meet the fundamental realities of the country of China.Therefore, be badly in need of a kind of suitable artificial saliva gland catheter product clinically, keep the unobstructed of postoperative conduit.Still there is not the report that artificial salivary gland conduit is implanted at present according to our interrelated data of inquiry.
Summary of the invention
Goal of the invention of the present utility model provides that a kind of this product can effectively prevent the generation of salivary gland ductal strictures for the artificial saliva gland conduit behind dilation of salivary gland duct art or the conduit lithotomy, keeps the unobstructed of salivary gland conduit.
The purpose of this utility model is achieved through the following technical solutions: artificial saliva gland conduit is characterized in that: conduit two ends internal diameter equates that external diameter increases progressively.
Described catheter proximal end external diameter is than the little 0.1mm of rear end external diameter.
The beneficial effects of the utility model: this product carries out the biological function design according to anatomical structure and the physiological function of salivary gland conduit, design the normal secretion that artificial catheter diameter can keep the unobstructed and saliva of conduit, the conduit configuration design is adopted certain tapering according to conduit traveling form, and the closely connected and conduit that is conducive to implantation catheter is kept certain degrees of expansion.This product composition is: polyethylene, physicochemical properties are stable, good biocompatibility, and human body is had no side effect.This product biggest advantage is exactly that its pipe thickness and caliber size are close to normal salivary ducts, implant the back salivary gland conduit has been played good dilating effect, help to prevent that postoperative conduit Secondary cases is narrow, kept the unobstructed of conduit simultaneously, helped the discharge of inflammatory mediator and carry out the interior flushing of conduit.And the histocompatibility of the artificial conduit of this kind is good, can not cause subject discomfort, only needs during use the conduit collar extension sewed up be fixed on every side on the mucosa, and is convenient during taking-up, safety.This product can solve the artificial salivary ducts thickness of pipe wall of traditional use, the problem that caliber is thin, and has safe and reliablely, simple to operate, easy to use, and advantage such as cost of manufacture is low can satisfy clinical extensive use.
