Abstract
A unilateral seton device for remedying the anal fistula consists of a piece of board and an elastic thread. The board is provided with holes for the two ends of the elastic thread to be put through. One end of the elastic thread which is put through the hole is provided with a bulging or a knot which is larger than the aperture, and the other end is a free end put through the hole. The free end is provided with a fixing block or a poise for frapping the elastic thread. The quite standard method and the measure of the unilateral seton treatment provided by the present invention provides the anal fistula seton therapeutics with a further development.
Description
Technical field
The present invention relates to a kind of operation device for the treatment of anal fistula, especially pressure control seton device.
Background technology
Anal fistula is commonly encountered diseases, adopting thread-drawing therapy treatment anal fistula is the most frequently used method, adopt an elastic threads in the hanging wire of existing treatment anal fistula, promptly run through the part that external sphincter deep layer and the pipeline more than the puborectalis communicate with the rectum internal orifice at the anal fistula trunk line, adopt the rubber band hanging wire, the one or many stringing is reined in out high-order sphincter at leisure.And can suitably tighten again according to the tightness of rubber band circle.Although ligating method for treating anal fistula is the important method of treatment anal fistula, owing to not having unidirectional seton device at present, uses common rubber band, thereby do not reach the effect of " myenteron is with length " the sphincter cutting of going in ring.In addition, because the pressure in the cutting can not be controlled, the rubber band tightness is arbitrarily grasped in operation by the doctor fully, and therefore to the power difference of muscle cutting, thereby clipping time is uncontrollable.
Summary of the invention
The present invention seeks to propose a kind of unidirectional seton device for the treatment of anal fistula, especially has pressure controlled unidirectional seton device, utilize elastica (rubber band etc.) that sphincter is carried out unidirectional cutting, especially make sphincter by near section of otch to distal cut, make the cutting edge healing of sphincter limit, can reach the effect of " myenteron is with length ", the generation of anal incontinence after the reduction anal fistulectomy.The object of the invention also is, proposes a kind of method owing to controlled pressure in the cutting, can cutting provide quantitative cutting force to muscle, therefore can the Cutting Control time.
The present invention seeks to realize like this: a kind of unidirectional seton device for the treatment of anal fistula, comprise that a plate and an elastica constitute, plate is provided with the hole of passing for the elastica two ends, an end that passes the elastica in hole is provided with bulging or the knotting greater than the aperture, and the other end is the free end that passes the hole, and free end is provided with fixedly card or the counterweight that tightens up elastica.Distance between two holes that confession elastica two ends are passed is 1-15mm.The present invention makes elastica run through the part cutting that the external sphincter deep layer communicates with the rectum internal orifice at the anal fistula trunk line in operation, the free end of elastica is tightened up, and can control the power of tightening up, in the cut ring of plate and elastica formation, the cutting force that the sphincter of elastica contact is subjected to is bigger, be cut earlier, the sphincter of plate contact is subjected to cutting force little; Can not be cut, to the last just can be cut open.A described plate is especially dull and stereotyped, also can be the plate of curved surface slightly.
Beneficial effect of the present invention: the invention provides the method and the means of the standard of comparison of unidirectional seton treatment, the anal fistula seton therapy is further developed; Theory of Chinese medical science thinks that also the far-end (sphincter the inner) that first cutting anal fistula trunk line runs through the part that the external sphincter deep layer communicates with the rectum internal orifice helps treating; Treatment anal fistula does not still have the quantitative approach of any anal fistula seton elastic force at present, can not constitute the therapy equipment of standard; The present invention uses dull and stereotyped contact to reduce pressure; Can use the length of elastica to estimate or more accurate calculating pressure; The length of using different counterweights or ply-yarn drill control elastic threads by the length of corresponding elastica, can quantitatively increase or reduce cutting strength to weigh cutting force.
Description of drawings
Fig. 1 is a structural representation of the present invention
Plate 1, elastica 2, the hole 3 that elastica passes, the scale of line are crossed 4, are fixed card (or counterweight) 5 among the figure.
The specific embodiment
Plate 1 can be dull and stereotyped or slightly arcual plate, elastica 2 can adopt rubber band or other high polymer elastic rope, plate to be provided with two holes of passing for elasticas, also can be provided with several holes more, select when passing at interval for elastica, distance between two holes that confession elastica two ends are passed selects often to be chosen as 1-11mm, unidirectional seton device design: contact at the lower end of internal sphincter use plate and with plate, adopt surface plate that plastic sheet constitutes or arc all can, elastic plate is better, thickness is about about 1mm.And the inner elastica that uses of sphincter, in apparatus of the present invention, under the situation that pressure equates, the pressure and the area that bear in the unit are are inversely proportional to, therefore an online lateral pressure is bigger, can form cutting and very little in a lateral pressure of surface plate to muscle, can not form cutting.Thereby reach the purpose of unidirectional cutting.The free end of elastica is fixed this free end at Kong Houshe one ply-yarn drill that passes on the plate, thereby the length of having determined elastica has promptly been determined cutting force.
In addition, because the pressure of prior art ring-type cutting can not control, therefore to the power difference of muscle cutting, thereby clipping time is uncontrollable, and the present invention sets the Cutting Control time by the elastic force of elastica.
Elastica of the present invention is provided with scale mark, uses length to come estimated pressure by the design flexibility line.Its method is, the comparatively constant elastica of pressure, its length is directly proportional with the tension force of generation, therefore with a certain line of length under relaxed state, according to its elasticity and length, can calculate first tension force promptly to the pressure of muscle, then according to the relation of power and length, make the counterweight of different pressures, when tightening up hanging wire gradually, use the size that the counterweight of different pressures can Cutting Control strength, the hanging wire that tightens up of control can (by the length of elastica) be arranged, or reach the effect of Cutting Control power, the blindness of avoiding tightening up hanging wire by the counterweight of Cutting Control strength.Fixing card is fixing with free end tension back, is provided with scale mark by elastica and also can quantitatively sets the power on the elastica.
