Abstract

The utility model relates to a dilator for medical application, which is composed of a tong type handle, a column hose, a towing steel wire, a universal joint, a valve cusp, a guide means, contrast agent, an injection tube, etc. The utility model has good effect on cardia achalasia operation losers. Only the mucous membrane anesthesia of throat part is needed, and the dilator is greatly easy to be inserted into oesophagus and the stomach. The dilatation treatment is effectively carried out when patients are in the state of waking, which avoids the pain, the dangerous danger, the complication and the sequelae of traditional chest cutting open operative treatment.

Description

II type cardia soft (fibre type) dilator

Exactly be to be used for maga-esophagus, the medical apparatus and instruments of krimer operation loser's dilation therapy is reined in the capable sea of maga-esophagus.The traditional treatment of maga-esophagus is to cut open the breast operation, and painful dangerous big, curative effect is undesirable, has complication to take place again.Non-operative treatment is a rubber pocket expansion method, and its weakness is that project power is little and need repeatedly insert rubber pocket, and expansion is long the course of treatment, and patient is greatly painful, and effect is also unsatisfactory.

The present invention is directed to the shortcoming of above-described apparatus and Therapeutic Method, develop a kind of therapeutic device (need not cut open the breast operation), for society provides a kind of project power big, put forth effort equilibrium, the soft dilator of I type of safety achalasia of the cardia.But I type dilator need be used guider, post flexible pipe nearly lobe leaf in garden is partly bent change the lobe leaf direction, operate more tired, the shortcoming of very flexible.At this shortcoming, developed gimbal suspension and substituted metal connecting tube between garden post flexible pipe and the lobe leaf.Constitute the soft dilator of II type, great advantage need not enabled guider, is hampered power and from line translation lobe leaf direction, motility is big according to lobe leaf front end, and is easy to operate and safe, is easy to grasp.It is II type dilator principal character.The following mode of the present invention realizes: by jaw type handle (1), and the dilator that garden post flexible pipe (16), traction steel wire (6), gimbal suspension (17), lobe leaf (19) and contrast-medium injection pipe (14) are formed.The lobe leaf is made up of plural blade.Material is rustless steel or metal chromium plating, rigid plastics.Expansion action is promptly to be opened by operator's grip pressure jaw type handle (1) nip part, pulling traction steel wire (6), and traction steel wire spurs the trace (21) of lobe leaf again, and trace pull-up lobe leaf pillar (20) struts the lobe leaf, finishes expansion and employs.Because being a kind of outsourcing one deck silicone rubber or plastics, garden post flexible pipe (16) has the contrast-medium injection pipe and the helical metal pipe of the draught line limiter tube that leads, so, can be inserted into the position that esophagus or gastric need be expanded easily from the oral cavity, because garden post flexible pipe (16) outside is with contrast-medium injection pipe (14), the operator can inject contrast agent as required at any time, is convenient to accurate lesions showed position.Because this dilator has gimbal suspension,, very easily insert and accurately be placed on the position that needs expansion so lobe leaf (19) is changed direction as required voluntarily.Guider is a kind of alternate configuration.

Be described in detail the present invention below in conjunction with embodiment and accompanying drawing thereof:

Fig. 1 is an outward appearance overall scheme of the present invention: 1-jaw type handle among the figure, the 2-spring leaf, 3-jaw type handle line shaft screw, leaf portion on the 4-jaw type handle jaw, 5-expansion amplitude restriction chi, the 6-traction steel wire, 7-fixed traction steel wire screw, 8-guide knob, 9-nut, 10-fixed guide draught line limit collar screw, 11-connects garden post flexible pipe metal tube, the 12-draught line that lead, the 13-draught line limiter tube that leads, 14-contrast-medium injection pipe, 15-guiding draught line limit collar, 16-garden post flexible pipe, 17-connects the gimbal suspension of garden post flexible pipe and lobe leaf, 18-guiding draught line bolt knot hole, 19-lobe leaf.

Fig. 2 is that two lobe leaves open sketch map, 20-lobe leaf pillar among the figure, 21-lobe leaf trace.

Fig. 3 is that four lobe leaves open sketch map.

Two parts of jaw type handle (1) are fixed together by line shaft screw (3), expansion amplitude restriction chi (5) one ends are screwed in jaw inferior lobe portion, the restriction chi passes through the restriction of leaf on jaw chi hole (see figure 1) can screw nut on the restriction chi according to the needs of lobe leaf expansion ratio, grip pressure jaw type handle (1) nip part opens during expansion, stretching screw (7) is fixed on the traction steel wire (6) of leaf front end on the jaw, the traction steel wire other end passes through the trace welding of the inner chamber and the lobe leaf of garden post flexible pipe (16), traction steel wire (6) by tension, affected trace (21), trace (21) pull-up lobe leaf pillar (20) again promptly opens the lobe leaf, reach dilating effect, the activity direction of lobe leaf passes through gimbal suspension, can change voluntarily, need not enable guider.Guider comprises knob (8), guiding draught line (12), guiding draught line limiter tube (13), guiding draught line limit collar (15), guiding draught line bolt knot hole (18).The both sides of the gimbal suspension (17) of draught line bolt knot Kong Zaiyuan post flexible pipe (16) and lobe leaf (19).Guiding draught line limiter tube is positioned at the both sides of garden post flexible pipe (16), and the contrast-medium injection pipe is positioned at wherein.Garden post flexible pipe (16) is no less than 300 millimeters, wraps up in one deck silicone rubber or plastics and guiding draught line limiter tube outward, and the helical metal flexible pipe that the opacifying injection pipe combines together, its end are connected on the gimbal suspension (17), and the other end connects on the metal tube (11).Traction steel wire (6) is that a multiply finer wire length is no less than 450 millimeters, and external diameter is decided with garden post flexible pipe inner chamber footpath, its end and trace (21) welding, and the other end is fixed on the front end of leaf (4) on jaw type handle (1) jaw with screw (7).Contrast-medium injection pipe (14) is no less than 450 millimeters, and intracavity diameter is no less than 0.5 millimeter.Lobe leaf (19) is the main body of mechanical expansion, and material is rustless steel or metal chromium plating, rigid plastics, and length is no less than 20 millimeters, and its external diameter is no less than 4 millimeters.The lobe leaf is expansible part, and the static part of lobe leaf is connected by screw socket with gimbal suspension (17).The trace of lobe leaf (21) welds together with traction steel wire, and trace (21) connects into Movable joint with lobe leaf pillar (20) with rivet.(see figure 2)

Carrying out the dilation therapy achalasia of the cardia with the present invention compared with prior art has the following advantages: patient only needs the bottleneck throat mucomembranous anesthesia, and patient accepts dilation therapy under waking state. This expander is very easily inserted by the oral cavity, and patient's misery is little, and is easy and simple to handle, is easy to grasp, and adjusting range restriction chi can reach the expansion of different amplitudes, can expand success so only need insert an expander. Project power is big. Put forth effort equilibrium, thoroughly fully, curative effect is good in expansion. Because being the mechanicalness expansion, pars cardiaca vagus nerve physiological function is injury-free, and pars cardiaca still has the sphincter effect, does not produce reflux esophagitis, and several no complication after the expansion are observed and can be advanced diet in 30 minutes. The expansion expense is few. The dilation therapy time is short, About 5-30 minute. Do not need medication need not have a rest after the expansion, work can work.
