Abstract

A suture forceps for excising external piles without removing silk features that the cross section of matched two teeth shows splayed shape, the contact surfaces are engaged in the mode of mouse teeth, upper tooth has needle slot, and its handle has self-locking mechanism.

Description

The stitching clamp of taking out stitches is exempted from the external hemorrhoid excision

One, technical field:

The present invention relates to technical field of medical instruments; The stitching clamp of taking out stitches is exempted from a kind of specifically external hemorrhoid excision.

Two, background technology:

There are following problems in conventional external hemorrhoidectomy: wound surface big, hemorrhage many, ligation is difficult, postoperative pain is heavy, reparation slow (about about 20 days).So some hospital adopts the excision suture.But it is inaccurate that para-position often appears in surgical stapling, suture needle enter organize darker, the postoperative easy infection.The more important thing is the postoperative difficulty of taking out stitches, bring the secondary misery to the patient.

Three, summary of the invention:

The present invention is made up of pincers handle, pincers tooth, self-locking mechanism.Two pincers teeth involutory transverse section are " eight " font, the upper limb contact, lower edge separates, the upper limb contact surface with the Mus dentation to nibbling.The upper clamp tooth face has many needle trays perpendicular to major axis that are parallel to each other, and self-locking mechanism is positioned at the handle place, is one group of horizontal bar composition of interlock mutually, utilizes elastic principle when clamping tooth to fashionable self-locking.The major axis extended line of the long axis direction of pincers tooth and pincers handle is 40 ° of left and right sides angles.

During use, the hand-hold pincers handle struts two pincers teeth, clamping external hemorrhoid root, and firmly clamping and self-locking are fixed, and are close on the pincers tooth plane and wipe out hemorrhoidal tissue, fixedly sew up under the state of edge of wound at pincers, one by one along needle tray stitching edge of wound, until having stitched whole edges of wound.Open self-locking pine pincers tooth, take out pliers.

Advantage of the present invention is to determine fully exactly to cut hemorrhoidal tissue in advance, and to be fixed before incised tissue oozing of blood not.Along pincers upper strata excision hemorrhoidal tissue, excise blood stasis so accurately, fast then, almost do not have hemorrhage, the wound surface nature, para-position is good.Because still edge of wound is sewed up in fixed needle tray pointwise on the pincers of edge of wound stationary state lower edge, the suture depth, separation criteria, stitching speed is fast, grasps easily.Suture comes off naturally after a few days.Because wound surface exposes few, healing time got final product about 10 days.The present invention has promptly shortened operating time, has alleviated patient's postoperative misery again, is very easy to doctor's treatment.

Four, description of drawings:

Fig. 2 is a side view of the present invention

Fig. 3 is pincers tooth schematic cross-sectional view

Five, the specific embodiment:

From Fig. 1, Fig. 2, Fig. 3 as can be known, the present invention is made up of pincers handle 4, pincers tooth 3, self-locking mechanism 5; The involutory transverse section of two pincers teeth is " eight " font, the upper limb contact, and lower edge separates; The upper limb contact surface with Mus tooth 2 shapes to nibbling; Pincers have above the tooth many be parallel to each other, perpendicular to the needle tray 1 of major axis, the width of needle tray 1 is about 1.5mm, about dark 2mm, about spacing 3.5mm; Self-locking mechanism 5 is positioned at the handle place, is one group of horizontal bar composition of interlock mutually; The major axis extended line of the long axis direction of pincers tooth and pincers handle is 40 ° of left and right sides angles.

Claims
