Background

A classic treatment method of clinically mixed hemorrhoids is the external stripping and internal ligation of mixed hemorrhoids. Peeling and cutting external hemorrhoids to the tooth line; the internal hemorrhoids are treated by thread or elastic loop ligation. The ligation process needs two persons to complete, the operator holds the tissue clamp by hand and lifts the tissue clamp to a sufficient height after the tissue clamp is clamped at the bottom of the hemorrhoid, and the ligation is completed by sheathing the bottom of the hemorrhoid with silk or elastic ferrules with medical assistance.

The tissue forceps used by the operator are shown in figures 1-2 and comprise two clamping arms 1 arranged crosswise, the two clamping arms 1 being hinged at the point of intersection by means of a pivot 4. The back end of each clamping arm 1 forms a finger ring 2, and the front end of each clamping arm 1 forms a bent jaw 3 for clamping hemorrhoids.

SUMMERY OF THE UTILITY MODEL

In view of the above problems, the present application aims to provide a hemorrhoid ligation apparatus so that one person can perform ligation of a hemorrhoid.

The hemorrhoid ligation device of the present application comprises a tissue forceps comprising a first arm and a second arm which are turnably cross-linked together by a pivot; the pivot shaft extends downwards to form a lower stop head beyond the first arm and the second arm, and the stop head is used for stopping the lower part of the elastic ferrule; the pivot shaft extends upwardly beyond the first and second arms; the upper end of the pivot is connected with a first release arm; the lower end of the first release arm is hinged at the upper end of the pivot; a second release arm is rotatably arranged at the upper end of the first release arm; the second release arm is integrally formed in a U-shape by two sub-arms, free ends of which are respectively formed with notches for supporting an upper portion of the elastic ferrule.

Handles are respectively formed on the outer sides of the two sub-arms of the second release arm.

The handle and the two sub-arms are formed on a horizontal plane.

When the first release arm and the second release arm are spread towards the jaw of the tissue forceps, the notches of the free ends of the two sub-arms exceed the foremost end of the jaw.

The width of the tissue forceps when the jaws are closed together is less than the spacing between the notches of the two sub-arms.

The haemorrhoids ligation device of this application for just can accomplish the ligature of haemorrhoids by one person, need not medical help and helps.

Detailed Description

The hemorrhoid ligation apparatus according to the present invention will be described in detail below with reference to the accompanying drawings.

The haemorrhoid ligation device of the present application is formed by improving the prior art tissue forceps.

The tissue forceps comprise two crosswise arranged clamping arms 1, being a first arm and a second arm, which are turnably cross-connected together in a crossing position by means of a pivot 4.

The pivot 4 extends downwards beyond the first and second arms forming a lower stop for the lower part of the elastic collar.

The pivot 4 extends upwardly beyond the first and second arms forming a notch 41. The upper end of the pivot 4 is used to mount the resilient collar release bracket. The resilient ferrule release bracket comprises a first release arm 5 and a second release arm 6. The upper end of the pivot 4 is connected with a first release arm 5; the lower end of the first release arm 5 is hinged in a notch 41 in the upper end of the pivot 4.

The upper end of the first release arm 5 is formed with a through hole to which the second release arm 6 is rotatably mounted.

The second release arm 6 is integrally formed in a U-shape by two sub-arms. The free ends of the two sub-arms are formed with notches 61, respectively, for supporting the upper portion of the elastic collar. The connection of the two sub-arms is rotatably mounted in the through hole of the first release arm 5.

Handles 62 are formed on the outer sides of the two sub-arms of the second release arm, respectively, for easy operation.

The handle 62 is formed in a horizontal plane with the two sub-arms.

The notches at the free ends of the two sub-arms extend beyond the forwardmost end of the jaw 3 when the first and second release arms 5, 6 are extended towards the jaw of the tissue forceps.

The width of the tissue forceps when the jaws 3 are closed together is smaller than the spacing between the notches of the two sub-arms of the second release arm.

When the elastic sleeve ring release support is used, the elastic sleeve ring release support is folded as shown in figures 3-4, the elastic sleeve ring is sleeved on the forceps mouth, the lower part of the elastic sleeve ring is sleeved on the lower side of the forceps mouth, the upper end of the elastic sleeve ring is sleeved in the notches of the two sub-arms of the second release arm, and at the moment, the forceps mouth can be freely opened and closed. One hand of the operator operates the finger ring of the tissue forceps, so that the forceps mouth clamps the haemorrhoids from the lower end. Then the forceps mouth is slightly lifted upwards, simultaneously, the other hand of the operator operates the handle to lift the elastic ferrule releasing support upwards, so that the angle between the second releasing arm and the first releasing arm is gradually increased, the notch of the second releasing arm moves towards the direction of the forceps mouth, the notch moves downwards after reaching the front of the haemorrhoids to reach the lower side of the sharp end of the forceps mouth, then the second releasing arm is retracted backwards, the upper end of the elastic ferrule is clamped at the front end of the lower part of the haemorrhoids, and the lower end of the elastic ferrule is clamped at the rear end of the lower part of the haemorrhoids. The whole process only needs a surgeon to finish by one person without medical assistance.
