Abstract

The anus expansion device of the utility model whose top end is conic is cylindrical. The anus expansion device is a cambered cylinder formed according to the physiological rectum curvature. The radian tangent starts from one third the length of the cylinder to the back end, and the angle beta between the tangent and the cylinder is from 8 DEG to 16 DEG. The back end of the anus expansion device is provided with a half section provided with a perforation for tying a rope, and the top end taper angle alpha of the anus expansion device is from 20 DEG to 55 DEG. The diameter of the anus expansion device is from 11 to 27 mm, and the length of the anus expansion device is from 19 to 20 cm. The improvements and advantages of the utility model are as follows: the half section of the cambered anus expansion device formed according to the physiological rectum curvature is well fixed in parallel with the supine body when expanding the anus, which can prevent the anus expansion device from turning and can avoid the perforation of intestine. The top end conic radian is reduced, so the utility model is adaptive to the tightness of the anal opening. Anal fissure and bleeding can be avoided. The back end of the anus expansion device is provided with the half section on which the model number is marked, and a small hole is drilled at the point of 6 mm to the back end of the half section. The anus expansion device is tied with a rope to prevent from sliding into the intestine cavity. The anus expansion devices of various model numbers with the diameters from 11 to 27 mm are provided for different patients.

Description

Medical anus-expanding unit

Technical field

This utility model relates to medical apparatus and instruments, especially a kind of anus-expanding unit.

Background technology

At present because the dirty source of environment is serious, dog-eat-dog, stress is big, and reasons such as some heredity and bad life habits, the patient who makes chronic constipation, ultrashort segment type, short segment type congenital megacolon, homology megacolon, anal draw together diseases such as the tight or anal stenosis of flesh increases year by year, needs to expand the anus expectant treatment.And postoperative patients such as the anastomotic stricture after the congenital anal atresia plasty, enterostomy stoma are narrow, megacolon anastomotic stenosis after surgery also often need to expand the anus expectant treatment.Anus-expanding unit is a kind of apparatus of these illness of treatment in the conservative treatment.Existing anus-expanding unit is that nose-circle taper radian is big, the metal bar of no camber, aluminium alloy bars, perspex bar are made.Its shortcoming is: the heavy anus edema that causes easily of (1) metal bar, (2) aluminium alloy bars nose-circle taper radian causes anal fissure and hemorrhage greatly easily, (3) the no certain camber of straight rod, sensation distending pain and discomfort when expanding anus, (4) anus-expanding unit rear end atresia tether, easily make anus-expanding unit slip into enteric cavity during misoperation, need operation to take out.

Summary of the invention

This utility model provides a kind of anus-expanding unit of making by rectum physiology curvature that camber is arranged, and has better therapeutic and safe in utilization in the hope of making it, and is easy and simple to handle.

Said anus-expanding unit integral body is cylindric, the top is conical, it is characterized in that: said anus-expanding unit is a kind of cylinder of making by rectum physiology curvature that radian is arranged, and the radian tangent line starts from from its rear end meter cylinder length 1/3, and tangent line and cylinder angle β are 8 °～16 °.Anus-expanding unit rear end starting point to 3.5CM place is the half section, and the half section is provided with a perforation in order to tether, and the top cone angle is 20 °～55 °, and the anus-expanding unit diameter is 11～27MM, and length is 19～20CM.

Compare with existing anus-expanding unit, improvements of the present utility model and advantage: one makes the anus-expanding unit of camber by rectum physiology curvature, half section and dorsal position health are parallel surface and fix when expanding anus, can prevent that anus-expanding unit from rotating up and down, avoid intestinal perforation; Two have dwindled nose-circle taper radian, can adapt to the anal orifice elasticity, have avoided anal fissure and hemorrhage; Three anus-expanding unit rear ends are the half section, above the entitling model; 6MM place, rear end, four half sections is drilled with an aperture, fastens rope and can prevent that anus-expanding unit from slipping into the intestinal chamber; Five diameter is arranged is that the anus-expanding unit of the various models of 11-27MM can be selected for different patients.

The specific embodiment

As shown in Figure 1 and Figure 2.Said anus-expanding unit is a kind of cylinder of making by rectum physiology curvature that radian is arranged 3, its rear end starting point to rear end 3.5CM place is half section 2, the half section is provided with a perforation 1 in order to tether, and top 4 is conical, and its summit cone angle is 20 °～55 °, best 33 °, the anus-expanding unit diameter is 11～27MM, and length is 19～20CM, and the radian tangent line starts from from its rear end meter cylinder length 1/3 (A shown in Figure 1 place), tangent line and cylinder angle β are 8 °～16 °, and the best is 12 °.

It is the different model of 11～27MM that anus-expanding unit has diameter, can satisfy the needs that different patients select.

Continue to expand anus 30 minutes every day with anus-expanding unit, proctostenosis is relaxed effectively, and stimulated enterokinesia, the intestinal peristalsis promoting dynamics is strengthened, the intestinal transportation function is accelerated, the gentle physical ability of defecating is discharged smoothly, has solved the constipation problem, has also reduced the generation that preoperative and postoperative And sends out disease (mainly being enterocolitis).To anastomotic stenosis after surgery or the narrow anus that expands of rectum fistulization oral, can make kiss and mouthful absent-mindedness; To the constipation of megacolon of newborn infant, abdominal distention, in poor condition of health, with different model anus-expanding unit expectant treatment, can make neonate tide over the initial hazards stage, improve the whole body situation, get ready for selecting the operation in suitable period later on.According to us research and the most expansion anus expectant treatments that pass through of the early stage light-duty infant of bibliographical information: NID (homology megacolon), obtained satisfactory result.

In order to reach the disposable sterilization effect, we will design the disposable rubber finger cot that matches with anus-expanding unit in addition.

The indication of said anus-expanding unit treatment comprises: after chronic constipation, ultrashort segment type, short segment type congenital megacolon, early stage light-duty NID, abdominal distention, anal are drawn together the tight or anal stenosis of flesh, congenital anal atresia plasty, the megacolon anastomotic stenosis after surgery, and enterostomy stoma is narrow etc.Use the anus-expanding unit expectant treatment, will in national pediatric surgery, anorectal surgical and chronic constipation patient, be widely used.
