Problems solved by technology

[0002] In the operation of high anal fistula, because the fistula is located as high as the muscle level of the puborectal ring, the removal of the fistula requires simultaneous removal of the puborectal ring, but because cutting the rectal ring muscle at one time will lead to serious complications such as fecal incontinence and anal displacement, rubber bands are used Tightening the puborectal ring achieves the purpose of chronic cutting, but the centripetal cutting force generated by the rubber band during the process of breaking the puborectal ring will lead to keyhole-like deformity of the anus after operation, which is not conducive to the recovery of anal function

Embodiment 1

[0026] Such as Figure 1-3 As shown, an adjustable continuous traction and hanging device for high anal fistula, including: a fixing belt 1, an adjusting belt 2, a fitting seat 3 and a traction unit 4, wherein:

[0027] One end of the adjustment belt 2 is movably connected to the fixing belt 1, and the other end of the adjustment belt 2 is connected to the fitting seat 3;

[0028] The center of the fitting seat 3 is provided with a defecation hole 31, and at least one traction unit 4 providing pulling force is arranged at the bottom of the fitting seat 3, and a rubber band is provided on the fitting seat 3 close to the traction unit 4. Hanging wire hole 32.

[0029] Such as image 3 , 4 As shown, the traction unit 4 includes: a base 41, an adjustment knob 42, an elastic member 43 and a traction hook 44, the base 41 is fixedly arranged at the bottom of the fitting seat 3, the adjustment knob 42 and the traction hook 44 is movably arranged on the base 41, the adjustment knob...

Embodiment 2

[0033] Such as Figure 5 As shown, in this embodiment, the traction unit 4 further includes a pulley 45, the pulley 45 is arranged on the base 41 close to the traction hook 44, and the rubber band is wound around the pulley 45 after passing through the hanging wire hole 32 and then hooked to the traction hook 44, the pulley 45 can make the rubber band traction smoother and reduce the sense of stuttering.

Embodiment 3

[0035] Such as Figure 6-8 As shown, in this embodiment, the traction unit 4 further includes: a housing 46, the housing 46 is covered on the base 41 and exposes the adjustment knob 42 and the traction hook 44, and the housing 46 46 is provided with a through scale groove 46a, and one end of the towing hook 44 inside the housing 46 is connected to a scale needle 44a, and the scale needle 44a extends to the outside of the housing 46 through the scale groove 46a. The scale needle 44a and the scale groove 46a can visually display the pulling force, and can quantitatively control the pulling force required according to the patient's condition.

Abstract

The invention provides an adjustable continuous traction thread hanging device for high anal fistula, and belongs to the field of medical instruments. The problems that a rubber band generates a centripetal cutting force in a pubic rectum ring tightening and breaking process after an anal fistula operation, a postoperative anus generates key-hole-like deformity, and anal function recovery is not facilitated are solved. The adjustable continuous traction thread hanging device comprises a fixing belt, an adjusting belt, a fitting seat and a traction unit. One end of the adjusting belt is movably connected to the fixing belt, and the other end of the adjusting belt is connected with the fitting seat; and a defecation hole is formed in the center of the fitting seat, at least one traction unit is arranged at the bottom of the fitting seat, and a wire hanging hole allowing a rubber band to penetrate through is formed in the fitting seat. The adjustable continuous traction thread hanging device for the high anal fistula has the beneficial effects that the fitting seat is fixed to the periphery of the anus, defecation of a patient is not affected, the rubber band can be gradually tensioned by rotating adjusting knobs on the traction units, the centripetal cutting force of the rubber band is adjusted to be one-way downward cutting force, so that the probability that key-hole-like deformity is generated on the anus after the operation is reduced, and postoperative wound rehabilitation is facilitated.
