Description

In-situ artificial Hyrtl's sphincter system

Technical field

The present invention relates to a kind of medical apparatus and instruments, particularly to a kind of in-situ artificial Hyrtl's sphincter system.

Background technology

Fecal incontinence（Fecal incontinence, FI）Also known as anal incontinence, it refers to that anus is unable to Autonomous Control liquid The discharge of body or solid manure, more than more than one month, is clinically mainly shown as patient's stool control ability partially or completely Lose.Fecal incontinence already becomes a global sociology and hygienic problems, exists as a kind of commonly encountered diseases and frequently-occurring disease Each national capital generally existing.Although this disease is not fatal, but bring the inconvenient and serious body and mind infringement of huge life to patient, The patient even having therefore loses the courage continuing to survive and selects extreme mode to terminate the life of oneself.U.S.'s last century nine There is up to 7.1% people to suffer from different degrees of stool in one larger scale clinical investigation display general population in the ten's to lose Prohibit, the incidence rate of fecal incontinence raises with the increase at age and the decline of psychophysiological state.The Wei You party so far of China Authority's report in face, but China human mortality substantial amounts, aging trend is increasingly severe, and China's economic development is uneven in addition Weighing apparatus, health care such as are yet to be completed at the reason, fecal incontinence China incidence it is contemplated that must allow of no optimist.

Following a few class can be broadly divided into according to cause of disease fecal incontinence：

1) congenital fecal incontinence：As congenital anal sphincter dysplasia or scarce.

2）Neurogenic fecal incontinence：A variety of causes leads to the disease of central nervous system and injured spinal cords, such as shock, in After wind, the temporary or permanent damage of central nervous system, all may occur in which temporary or permanent fecal incontinence；If Breast, waist, sacrum vertebral fracture compression spinal cord or spinal nerves, may result in paraplegia thus causing fecal incontinence；In addition, rectum is close After mucous membrane resection at anus, rectal wall enteroception neurologic defect also can cause fecal incontinence.

3）Myogenic fecal incontinence：Anal sphincter is impaired and to include about hypofunction be lead to fecal incontinence common former Cause.The easypro contracting of anus and bowel movement function are the effectors such as the interior external sphincter innervating and levator ani m. to be completed.These Muscle tone declines, and relaxes, or cut-off, excision, or forms large area cicatrix, all can cause fecal incontinence.As hemorrhoid, rectum The crissum that prolapsus, polyp abjection cause is of flaccid muscles, tension force decline also results in fecal incontinence.Some old patients can Crissum muscular dystrophy fecal incontinence occurs.The cut-out of the disease surgeries such as ano -rectal manometry, anal fistula or excision sphincter May result in fecal incontinence.

4）Perineal position wound or maternal infuries：Because wound or childbirth cause perineal position tear to lead to anal sphincter impaired or scarce As.Strictly speaking wound can be respectively belonging to neurogenic or myogenic fecal incontinence according to damage location difference；Here it So by single-row to wound and maternal infuries out because they are the common cause causing fecal incontinence, particularly the latter, it has been reported that There are about 35% through cloudy pregnant woman suffer from sphincter injury.This just can explain why women proportion in fecal incontinence High compared with male.

5）Rectal neoplasm：The sickness rate of colorectal carcinoma occupies the prostatitis of human tumor, and global colorectal cancer is newly sent out every year Case reach 940,000 change because of dietary structure in China due to mid-low rectal cancer incidence rate have the trend raising year by year. Radical surgery is the first-selected remedy measures for the treatment of colorectal cancer, for Low Rectal, because its tumour growth position Too low, for reaching surgical radical treatment purpose, excision anus becomes a kind of cruelty but helpless selection.

The treatment of fecal incontinence increasingly causes the attention of countries in the world medical worker, in order that Patients with Fecal Incontinence recovers Stool control mode ability, scholars have carried out many research and have attempted, and summarize and define a series of Therapeutic Method.At present, It is internal medicine conservative treatment and surgical operation therapy that the common method of various countries' treatment fecal incontinence may be summarized to be two big class.Wherein interior Section's expectant treatment has：

1）Drug therapy：Medicine conditioning is the first step of most patient treatment, and the practical situation according to patient uses and leads Cathartic, diarrhea and extender etc.；Certainly also can carry out traditional Chinese medical herbal treatment such as to take invigorating the spleen and replenishing QI, rise this solid de- prescription. The symptom of part mild patient's fecal incontinence can therefore obtain a certain degree of improvement.

2）Muscle of perineum is trained：Kegel et al. delivers the literary composition with regard to perineum training for treatment fecal incontinence and urinary incontinence earliest Chapter, perineum shrinks the tonicity that exercise can significantly improve puborectaliss and levator ani m., in any vacant time, through enough Training, feces Autonomous Control ability can be significantly improved.Many scholars were as a base therapy method later, But perineum training is only applicable to slack anus, shrinks powerless patient, and can only alleviate fecal incontinence to a certain extent Problem, inapplicable for no sphincter patient.

3) biofeedback therapy:Biofeedback therapy treats fecal incontinence principle：By mechanically or electrically sub-device by anus The feedback signal of pipe rectum presents in visual form trainer, and trainer, according to signal intensity, compares normal signal instruction Practice, strengthen crissum muscular contraction force, the purpose of Rectal Sensitivity to reach.Biofeedback therapy can strengthen nerve control The muscular strength of muscle, but will not repair or generate new nervous pathway.Biofeedback therapy is for having part rectum perceptive function Effective with the patient of spontaneous contractions function, therefore the patient outcomes for urge incontinence are better than the patient of passive incontinence. Situations below is all not suitable for biofeedback therapy：A, serious anal sphincter injury；B, serious anus sensation are damaged；C, anus Door internal sphincter Resting Pressure is too low；D, pudendum ML extend；E, anal incontinence are with constipation by outlet obstruction.

4) electronic stimulation:Electronic stimulation is that an electrode special is inserted after anus, uses galvanic stimulation anus Sphincter and Pelvic floor.As a kind of Therapeutic Method of auxiliary, it is usually used in nerves fecal incontinence, late result is not affirmed.

The treatment of internal medicine conservative treatment only applicable part patient with slight symptoms, and often can only improve stool to a certain extent The situation of incontinence, can not fundamentally solve the problems, such as fecal incontinence；For fecal incontinence patient with severe symptoms more seem power not from The heart.Therefore surgical operation therapy often becomes the unique selection of patient with severe symptoms.Common therapeutic method of surgery has：

1）Anal sphincter kposthesiss：The sphincter two ends scar tissue of cut-out is separated, sutures.It is used for damaging soon Case, sphincter has function part to account for 1/2.As wound infection should be repaired within 6～December, otherwise sphincter once withers Contracting becomes fibrous tissue, finds and suture is all extremely difficult in art；

2）Sphincteroplasty：Multiplex gracilis or gluteus maximus are transplanted around anal canal at present, replace or strengthen sphincter Function.It is applied to sphincter to destroy completely or congenital no sphincter, and can not be with the patient of Sphincter repair art treatment.This Although kind of a method makes moderate progress to stool control mode ability, there is also the requirement that sphincter function can not meet control completely, when dilute Just it may appear that " leakage excrement " phenomenon or when motion intra-abdominal pressure increases.Simultaneously as operation complexity, complication are many（Intestinal tube is narrow, near End intestinal tube Secondary cases expansion, scar hyperplasia, graft muscle fatigue deformation etc.）, often lead to Endodontic failure；

3）Colonic diversion：Ostomy will the colon of near-end each layer is sutured with stomach wall, form artificial anuss.Strictly speaking Colonic diversion is not a kind of method treating fecal incontinence, because colonic diversion is still a kind of fecal incontinence state in itself.To the greatest extent So, permanent colonic diversion is still the most frequently used helpless selection solving the problems, such as defecation after low rectal cancer at present to pipe.Knot Intestinal ostomy not only using inconvenience, also can cause serious personality defect and the very big puzzlement of body and mind to patient.

Inspired by urinary tract artificial sphincter system successful Application, people begin attempt to adopt artificial anal sphincter To treat fecal incontinence.Successively be born set bellows artificial sphincter system, memorial alloy formula artificial sphincter system and electromagnetism Ferrum formula artificial sphincter system.During realizing the present invention, inventor finds that in prior art, at least there are the following problems： Although these sphincter system operation principles are different in prior art, it is all to close intestinal tube by folder to realize to excrement stream Management and control, but intestinal tube is unlike urinary system, it is highstrung to ischemia, and folder closes the excessive intestinal tube that may result in of pressure and lacks Blood necrosis, folder closes the too small excrement stream that may result in of pressure and cannot be controlled completely, causes fecal incontinence.Unfortunately although various countries Scholar has paid unremitting effort for this, but does not find the method solving stress problems well all the time.In the past various artificial anus Door sphincter does not all take into full account tissue fusion problem, and they are lacked with surrounding tissue and effectively fix it is easy to lead in addition Prosthese in vivo the change of position and dead space occurs.The presence of dead space inherently hydrops, a major reason of infection.Cause This, except this root problem of stress problems, the high infection rate in tissue fusion and device displacement problem, are also artificial anus in the past The major reason that door sphincter system does not make a breakthrough in treatment fecal incontinence.

Content of the invention

The technical problem to be solved in the present invention is the drawbacks described above how overcoming prior art, provides a kind of in-situ artificial straight Intestinal sphincter system.This in-situ artificial Hyrtl's sphincter system one is the pressurized ischemia of effectively solving intestinal tube and stool can not be complete The contradiction of restraining is stress problems；Two is effectively solving tissue fusion problem, allows prosthese and autologous tissue to combine together, has two sides Face acts on：Contribute to first fixed fae body do not allow its displacement, its two can help to reduce infection generation.

Technical scheme is as follows：

A kind of this in-situ artificial Hyrtl's sphincter system, including artificial Hyrtl's sphincter body and sphincter folding control dress Put；

Described artificial Hyrtl's sphincter body be in hollow cylindrical structure, its be followed successively by from inside to outside artificial rectum enteric cavity, The internal layer silicone rubber membrane of responsible sphincter folding, sphincter blister cavities, intermediate layer silicane rubber plate, the artificial Hyrtl's sphincter body of covering Entirely outside outer layer stereo weaving polyester mesh sheet；

The inside opisthotonos of described outer layer stereo weaving polyester mesh sheet upper and lower ends cover internal layer silicone rubber membrane, respectively upper end to Interior opisthotonos stereo weaving polyester mesh sheet and lower end inside opisthotonos stereo weaving polyester mesh sheet；

Described sphincter folding control device includes sphincter conduit, and described sphincter tube at one end is opened on sphincter capsule Chamber, the other end is connected with the unidirectional anti-valve that backflows.

It is so designed that, first, by using artificial Hyrtl's sphincter body, efficiently solving any one in the past and manually including The sphincter pressure problem that about flesh all cannot solve very well.Artificial rectum allows host's intestinal tube thoroughly free out from pressure, Due to the worry without intestinal tube ischemic necrosis, realize the closing of artificial rectum enteric cavity and opening will be easily a lot.

Secondly, set up stereo weaving polyester webs lamella：Draw conventional artificial anal sphincter and do not carry out necessary fixation, easily Produce displacement, and lead to the lesson of failure of apparatus, therefore set up stereo weaving polyester webs lamella, be beneficial to device and obtain in vivo To fixedly securing.Except fixation, prior purpose is that host's intestinal tube can fusion growth can be integrated with artificial rectum. In addition, setting up of polyester webs lamella expands outwardly, thus being conducive to when can also limit the work of this artificial sphincter system Mitigate to the extruding infringement of surrounding tissue and the sense of discomfort of patient.

Then, do filling sacculus medium using air：Using air do medium except because aboundresources complete, with Outside handss can use, also a reason is exactly light.Quality due to air is almost negligible, thus without as heavy Liquid media can allow patient do not feel like oneself like that or cause because of effect of inertia device to shift.

As optimization, described sphincter folding control device is also included for real-time detection artificial rectum intestinal cavity pressure Pressure transducer, and the described sphincter conduit being connected with the unidirectional anti-valve that backflows is simultaneously connected with pressure indicating alarm device.So Design, by arranging pressure transducer and pressure indicating alarm device, makes patient learn enteric cavity pressure change in time, reminds patient Defecation, more humane.

As optimization, described intermediate layer silicane rubber plate thickness is 4-6 times of internal layer silicone rubber membrane thickness；Described internal layer silicon rubber Glued membrane and intermediate layer silicane rubber plate upper and lower ends closely connect as one, and described sphincter blister cavities is internal layer silicone rubber membrane and centre The airtight lacuna constituting in the middle of layer silicane rubber plate.It is so designed that, internal layer silicone rubber can be made when to sphincter blister cavities gas injection Film centration is expanded, and while meeting closure artificial rectum, reduces artificial rectal tube to greatest extent because by reverse extrusion masterpiece With and the deformation that causes, thus reduce artificial rectal tube damaging to the extruding of surrounding tissue, and may lead to because deformation is excessive Dead space and infection risk.

As optimization, described artificial Hyrtl's sphincter body hypomere in rectum is former near the position of anus or patient Come the position of anus.Patient row Abdominal pelvic resection being excised to anus should be located at the position of the original anus of patient.So, Designed by " in situ ", it is to avoid patient suffers from the embarrassment of abdominal part fistulation and helpless situation, so that them can be obtained almost normal The quality of life of people, regain the confidence of life, in addition, being easily installed and range of application is wider.

As optimization, the height of described sphincter blister cavities is that to deduct upper end inwardly anti-for the height of artificial Hyrtl's sphincter body The height of folding up body Woven polyester mesh sheet and lower end inside opisthotonos stereo weaving polyester mesh sheet.It is so designed that, be easy to process and make Preferable with effect.

As optimization, described sphincter catheter opening is located in described sphincter blister cavities in the end of sphincter blister cavities Portion.It is so designed that, be easily installed and using effect is preferable.

As optimization, described pressure transducer and airway share same opening or single opening in artificial rectum enteric cavity Top.It is so designed that, be easily installed and using effect is preferable.

Technical scheme has the advantages that：

The present invention, structure is simple, design science, novel, cost is very low, simple to operate, easy to use, first, " in situ " design, it is to avoid patient suffers from the embarrassment of abdominal part fistulation and helpless situation, makes them can obtain intimate ordinary person's Quality of life, regain the confidence of life；In addition, this in-situ artificial Hyrtl's sphincter system due to initiative propose manually straight The concept of intestinal, the contradiction between the pressurized ischemic necrosis of intestinal tube and fecal incontinence is therefore resolved；Additionally, this sphincter system is abundant Consider tissue fusion problem and devise outer layer solid braided polyester stratum reticulare, this design one side can play fixed fae body and not allow The purpose of its movement, on the other hand can also allow prosthese and the growth of patient autologous tissue combine together thus reducing sending out of infection Raw.Finally, sphincteral folding is controlled using air, air in addition to resource can use everywhere, almost can neglect by its quality Slightly disregard, this make it will not as other sphincter systems, because of excessively heavy easy because effect of inertia displacement, lead to Device failure.

Specific embodiment

For making the objects, technical solutions and advantages of the present invention become more apparent, develop simultaneously embodiment referring to the drawings, right The present invention further describes.

As shown in Figure 1-Figure 3, this in-situ artificial Hyrtl's sphincter system is according to laboratory animal（Bama of Guangxi perfume pig）Build Design, including artificial Hyrtl's sphincter body 1 and sphincter folding control device 2；

Described artificial Hyrtl's sphincter body 1 is in hollow cylindrical structure, and it is followed successively by artificial rectum enteric cavity from inside to outside 1.1st, the internal layer silicone rubber membrane 1.2 of responsible sphincter folding, sphincter blister cavities 1.3, intermediate layer silicane rubber plate 1.4, covering are artificial The outer layer stereo weaving polyester mesh sheet 1.5 of the whole outside of Hyrtl's sphincter body 1；

Described intermediate layer silicane rubber plate 1.4 thickness is 5 times of internal layer silicone rubber membrane 1.2 thickness；Described internal layer silicone rubber membrane 1.2 and intermediate layer silicane rubber plate 1.4 upper and lower ends closely connect as one, described sphincter blister cavities 1.3 be internal layer silicone rubber membrane 1.2 and intermediate layer silicane rubber plate 1.4 in the middle of constitute airtight lacuna；Described outer layer stereo weaving polyester mesh sheet is two about 1.5 Inside opisthotonos are held to cover internal layer silicone rubber membrane 1.2, the respectively inside opisthotonos in upper end stereo weaving polyester mesh sheet 1.6 and lower end is inside Opisthotonos stereo weaving polyester mesh sheet 1.7；

Described sphincter folding control device 2 includes sphincter conduit 2.1, described sphincter conduit 2.1 one end open in Sphincter blister cavities 1.3, the other end is connected with the unidirectional anti-valve 2.2 that backflows.

Specifically, described sphincter folding control device 2 is also included for pressure in real-time detection artificial rectum enteric cavity 1.1 Pressure transducer, and the described sphincter conduit 2.1 being connected with the unidirectional anti-valve 2.2 that backflows is simultaneously connected with pressure instruction and reports to the police and fill Put 2.3.So, pressure transducer real-time detection artificial rectum intestinal cavity pressure, and pass through pressure-indication means real time reaction intestinal Cavity pressure changes, and will trigger warning when pressure reaches certain value, sends the sound and reminds patient to remove defecation.

Specifically, described artificial Hyrtl's sphincter body 1 in rectum hypomere near the position of anus.

Specifically, the height of described sphincter blister cavities 1.3 is that to deduct upper end inside for the height of artificial Hyrtl's sphincter body 1 The height of opisthotonos stereo weaving polyester mesh sheet 1.6 and lower end inside opisthotonos stereo weaving polyester mesh sheet 1.7.

Specifically, described sphincter conduit 2.1 is opened on the end of sphincter blister cavities 1.3 positioned at described sphincter blister cavities 1.3 middle part.

Specifically, described pressure transducer and airway share same opening.

Specifically, the height of described artificial Hyrtl's sphincter body 1 is 30mm, and external diameter is 20mm.

Specifically, described intermediate layer silicane rubber plate 1.4 thickness is 5 times of internal layer silicone rubber membrane 1.2 thickness, and described internal layer The thickness of silicone rubber membrane 1.2 is 0.2mm, and its effect is responsible for closing or open artificial rectum；The thickness of intermediate layer silicane rubber plate 1.4 Spend for 1mm, for artificial rectum main part, because intermediate layer silicane rubber plate 1.4 thickness exceeds well over internal layer silicone rubber membrane 1.2, and The former is 5 times of the latter, and internal layer silicone rubber membrane 1.2 centration so can be made when to sphincter blister cavities 1.3 gas injection to expand, While meeting closure artificial rectum, reduce artificial rectal tube to greatest extent because of the deformation being caused by the effect of reverse extrusion power, Thus reduce artificial rectal tube the extruding of surrounding tissue is damaged, and the wind because of the excessive dead space that may lead to of deformation and infection Danger.

Specifically, the material of described sphincter conduit 2.1 is silicone rubber, and its length is 200mm, and external diameter is 3mm, and internal diameter is 1.5mm.

Artificial sphincter main part outermost layer is to be made up of stereo weaving polyester mesh sheet, stereo weaving polyester mesh sheet except Cover artificial rectum entirely outside outer, also need to cover each 5mm of internal layer upper and lower ends from the inside opisthotonos of upper and lower ends, that is, upper end is inside The height of opisthotonos stereo weaving polyester mesh sheet 1.6 and lower end inside opisthotonos stereo weaving polyester mesh sheet 1.7 is 5mm.（As figure 1）.Why so design, main purpose is the artificial Hyrtl's sphincter prosthese of solution and intestinal tube and surrounding tissue fusion growth is The problem of one.In addition, because the presence of stereo net sheet is so that artificial rectum is more difficult to profile under gas pressure Become, be more beneficial for mitigating the formation that patient does not accommodate Periprosthetic dead space.Stereo weaving polyester mesh sheet, polypropylene mesh, varicosity Politef mesh sheet is all the mesh sheet of comparative maturity, all has very high biocompatibility, and toxic and side effects are low, physicochemical property is steady Surely it is good artificial prosthesis material.Why select the former be because stereo weaving polyester mesh sheet compared with polypropylene mesh all There is big mesh design, suitable granulation tissue and immunocyte enter and have stronger anti-infection ability（Avoid Periprosthetic sense Dye is to ensure that the premise that prosthese and surrounding tissue combine together）；But stereo weaving polyester mesh sheet quality is than polypropylene net Piece is soft, and plasticity is strong, is more suitable for folded deformation.Although expanded PTFE soft texture is suitable for folding plastotype, due to Its mesh is too small, and granulation tissue and macrophage etc. hardly enter, and leads to its anti-infection ability relatively low, easily causes sending out of infection Raw.In addition, in e-PTFE four ethylene body, crimp contraction is too high, easily causes prosthese to deform, and then affect it including about work( Energy.

In addition, the height of described artificial Hyrtl's sphincter body and external diameter can be carried out suitably according to patient's intestinal tube external diameter is different Adjustment.The length of described sphincter conduit is suitably adjusted also dependent on patient size.

Operation principle：

First passing through operation will be together with artificial rectum and patient's intestinal tube stage casing coincide, due to devising outer layer stereo weaving Polyester mesh sheet, and outer layer stereo weaving polyester mesh sheet all inside opisthotonos up and down, this allows patient's intestinal tube and artificial rectum Growth combines together, and realizes the seriality of intestinal tube.Generation in order to prevent from infecting will take strict sterile working, and carries out The provisional fistulation of colon, in case fecal pollution anastomotic stoma leads to poor healing.After Using prosthesis March, through cardiografin radiography Confirm anastomotic healing firmly, intestinal tube seriality is well it is possible to start artificial Hyrtl's sphincter system.

As shown in Fig. 2 passing through sphincter conduit to sphincter blister cavities gas injection through the unidirectional anti-valve that backflows, treat in sphincter blister cavities After reaching certain pressure, internal layer silicone rubber membrane centration will expand and finally block artificial rectum enteric cavity, prevents returning due to unidirectional Stream valve resilience, gas is unable to Self-discharged, invariable such that it is able to the long-time pressure maintaining in sphincter blister cavities, realizes length When close enteric cavity, restraining excrement stream purpose；When having gas or feces to accumulate in enteric cavity, artificial rectum intestinal cavity pressure change can be led to Cross internal layer silicone rubber membrane and be communicated to pressure indicating alarm device through sphincter conduit, when pressure reaches setting pressure, pressure refers to Show that alarm device can send audible alarm, remind patient to remove defecation.As shown in figure 3, now only needing patient to be vented gas, internal layer Silicone rubber membrane can rapid resilience under natural resiliency effect, artificial rectum enteric cavity reopens, and stool just can be discharged.So Not only achieve the control to stool but also do not result in the pressurized ischemic necrosis of intestinal tube due to not extruding patient itself intestinal tube, by Can be adjusted according to everyone different situations in pressure, no matter which kind of form patient, for which kind of state, is greatly（Gu Body, semisolid, liquid）All without the possibility that fecal incontinence occurs.This sphincter system folding only needs to 10 seconds left sides after tested The right side, compared with existing artificial anal sphincter device（60 seconds at least other artificial anal sphincter folding used times, many both at home and abroad Then 6-7 minute）It is clear that obvious superiority is also had on response speed.

Above-mentioned in-situ artificial Hyrtl's sphincter system, structure is simple, design science, novel, cost is very low, operation Simply, easy to use, first, " in situ " is designed, it is to avoid patient suffers from the embarrassment of abdominal part fistulation and helpless situation, makes them The quality of life of intimate ordinary person can be obtained, regain the confidence of life；In addition, this in-situ artificial Hyrtl's sphincter system is due to head The invasive concept proposing artificial rectum, the contradiction between the pressurized ischemic necrosis of intestinal tube and fecal incontinence is therefore resolved；This Outward, this sphincter system has taken into full account that tissue fusion problem devises outer layer solid braided polyester stratum reticulare, and this design is on the one hand Fixed fae body can be played and do not allow the purpose of its movement, prosthese and the growth of patient autologous tissue on the other hand can also be allowed to melt as one Body is thus reduce the generation of infection.Finally, sphincteral folding is controlled using air, air except resource everywhere can use in addition to, Its quality is almost negligible, and this makes it will not be as other sphincter systems, because excessively heavy and easy Because of effect of inertia displacement, lead to device failure.

Above-mentioned specific embodiment is only the concrete case of the present invention, is not the restriction that the present invention is made with other forms, Any those skilled in the art are changed or are modified as equivalent variations possibly also with the technology contents of the disclosure above Equivalent embodiments.But every content without departing from technical solution of the present invention, the technical spirit according to the present invention is implemented to above Any simple modification, equivalent variations and remodeling that example is made, all should fall into the scope of patent protection of the present invention.
