Description

Ligature forceps for hypertrophy of anal papilla

Technical Field

The application relates to a medical appliance, in particular to a pair of ligation forceps for anal papilla hypertrophy.

Background

Patients with hypertrophy of the anal papilla are often encountered in outpatient clinics. The anal papilla is thin at the root and large at the head, and is usually treated by ligation. When the anal papilla is enlarged and ligated, a curved forceps is often used, as shown in fig. 1, and comprises two clamping arms which are hinged together; the front end of the first clamping arm 1a is a first elbow 31, the front end of the second clamping arm 1b is a second clamping arm 32, and the rear end of each clamping arm is a finger ring 2.

The conventional operation is that the elbow of the curved forceps is used for clamping the root of the anal papilla, and the ligature is sleeved on the root of the anal papilla by hands. The operation needs to be implemented under an anoscope, the space is very limited, and the operation is very inconvenient.

SUMMERY OF THE UTILITY MODEL

In view of the above problems, the present application aims to provide a ligature forceps for hypertrophy of anal papilla, by which the anal papilla can be conveniently sleeved in the rectum of a patient, and ligature can be conveniently performed.

The ligating forceps for hypertrophy of anal papilla comprises a first clamping arm and a second clamping arm; the front end of the first clamping arm forms a first elbow, and the front end of the second clamping arm forms a second elbow;

a circular pore channel is formed on the first side of the first elbow; a clamping groove is formed on the second side of the first elbow; the clamping groove is used for detachably clamping the elastic clamp; the pore channel is communicated with the clamping groove; one end of the ligature passes through the pore passage and is fixed on the elastic clip;

a concave cavity is formed on the first side of the second elbow, and a clamping rod is longitudinally formed in the concave cavity;

the position of the clamping groove corresponds to the position of the recess;

the elastic clip is formed into a ring body, the first end and the second end of the elastic clip are overlapped, and the overlapped first end and the second end form a V-shaped guide port;

when the elastic clip is inserted into the clamping groove, the V-shaped guide port is opposite to the clamping column.

Preferably, the second bend is formed with a threaded hole at the top of the pocket; the uprights are formed by bolts inserted from threaded holes into the recesses.

The hypertrophy ligature forceps for the anal papilla have the advantages that the clip is transferred to the second elbow from the first elbow when the first elbow and the second elbow are clamped, so that the ligature fixed on the clip is also brought to the second elbow, the ligature is detoured from the rear side of the anal papilla, and the ligation forceps are very convenient to use.

Detailed Description

Hereinafter, the ligating forceps for hypertrophy of anal papilla according to the present invention will be described in detail with reference to the accompanying drawings.

The ligating forceps for hypertrophy of anal papilla comprises a first clamping arm and a second clamping arm; the front end of the first clip arm forms a first bend 31 and the front end of the second clip arm forms a second bend 32.

A first side of the first elbow 31 is formed with a circular hole 31b; a clamping groove 31a is formed at the second side of the first elbow 31; the clamping groove 31a is used for detachably clamping the elastic clamp 4; the hole 31b is communicated with the clamping groove 31a; one end of the ligature 5 passes through the hole 31b and then is fixed on the elastic clip 4.

The second bend 32 has a recess 32a formed in a first side thereof, and a catch 32b formed longitudinally in the recess 32 a.

The position of the card slot 31a corresponds to the position of the pocket 32 a.

The spring clip 4 is formed as a loop with a first end 41 and a second end 42 overlapping, and the overlapping first end 41 and second end 42 forming a V-shaped guide opening.

When the spring clip 4 is inserted into the slot 31a, the V-shaped guide opening faces the clip post 32b.

In another embodiment, the second bend 32 is formed with a threaded hole at the top of the recess 32 a; the upright 32b is formed of a bolt, which is inserted into the recess 32 from the threaded hole, as shown in fig. 9.

When the anal papilla clamp is used, firstly, the ligature is fixed on the elastic clamp after passing through the pore channel, then the elastic clamp is clamped in the clamping groove, then the first elbow and the second elbow respectively pass through the two sides of the anal papilla from front to back, and the first elbow and the second elbow are clamped after the clamping groove and the recess of the first elbow and the second elbow cross the root of the anal papilla; in the clamping process, the upright post in the recess presses the elastic clamp along the V-shaped guide port of the elastic clamp, so that one side of the clamping groove of the first end and the second end of the elastic clamp is bent, the first end and the second end which are overlapped are temporarily separated to form a notch, the clamping column enters the elastic clamp from the notch, the first end and the second end are separated from the upright post, and the elastic clamp is restored to the original state and overlapped together. Then the clamping state of the first elbow and the second elbow is released, the first elbow and the second elbow are separated, the stand column can take the elastic clamp to pull out the stand column from the clamping groove and only sleeve the stand column, and the ligature is led to the second elbow from the first elbow by bypassing the rear side of the anal papilla; at the moment, the first elbow and the second elbow are drawn out, and the ligature is taken out, so that the ligature can be finished easily.
