Abstract

The utility model relates to a cambered suturing needle with two tips, two holes and two grooves, the cambered suturing needle has the radian of 1/2, a needle body of the cambered suturing needle is circular, the thickest diameter of the middle of the needle body is from 1 to 1.2 mm, the tips of both ends of the needle are in a three-cornered shape or a circular shape, the moving points of the tips and the needle body are both provided with treading holes (inner and outer directions) which can be passed by a No.7 thread, and the inner surface and the outer surface of the needle body are provided with shallow grooves which can hide the No.7 thread. The suturing needle is divided into three types of 2 cm, 2.5 cm and 3 cm according to the chord length and is made of stainless steel, and the cambered suturing needle is suitable for celioscope hernial sac high ligation to treat pediatric indirect hernia.

Description

Two sharp diplopore double flute circle curved suture needles

Technical field

This utility model relates to a kind of medical suture needle, is applicable to peritoneoscope hernical sac high ligation treatment indirect inguinal hernia in children.

Background technology

Peritoneoscope hernical sac high ligation is the new method of the developed recently minimally-invasive treatment indirect inguinal hernia in children of getting up, and sewing and looper body surface sewing in staight needle body surface puncture method, the looper abdomen are arranged.The improvement key of sewing method is the improvement of sewing needle.State-of-the-art before this method is to utilize two sharp sewing needle body surface sewings.This sewing needle has obtained china national practical new-type patent, the patent No.: ZL200420040364.4 by developments such as Zhang Jincheng.This pin is similar to the ordinary sewing pin, and different is that its two ends all have needle point, is about 2cm, is 3/8～1/2 radian.Through wires hole is positioned at the tail tip of pin, and the point of syringe needle is rhizoma sparganic shape or circle (Fig. 1).Earlier see interior collar extension clearly during application with peritoneoscope.Two sharp sewing needles thrust from the body surface projection place of interior collar extension, by the inboard inserting needle of interior collar extension from top to bottom, outwards sew up by interior collar extension below again, sewing needle has been crossed behind the interior collar extension below pin has been pierced through skin on outwards, needle holder clamping needle point, sew up the top of collar extension outside to inside by the outside peritoneum of interior collar extension then, the backshank point is passed from former skin inserting needle hole take suture out of, mention the suture two ends and tie a knot in subcutaneous tissue ^[1]This method is that complete peritoneum is sewed up outward, do not have the infull situation of the peritoneum of stitching, so relapse rate is extremely low, and easy easy and simple to handle, compared with a much progress really of other method.But two sharp sewing needles have only a fairlead, with the backshank point when former skin inserting needle hole direction is sewed up (backstitching), because the suture head and the tail all on hernia ring peritoneum outer ring track, drag effort, operation inconvenience.

Summary of the invention

In order to remedy the deficiency of two sharp sewing needles, this utility model provides a kind of sewing needle---two sharp diplopore double flute circle curved suture needles.

The technical scheme that its technical problem that solves this utility model adopts is: on the basis of two sharp sewing needles, the arc pin is set at 1/2 radian, needle body is circular, needle body middle part thickness diameter 1～1.2mm, and the two ends needle point is set at rhizoma sparganic shape or circle, needle point and the needle body place of dividing a word with a hyphen at the end of a line are equipped with through wires hole (inward-outward direction), can hold No. 7 silk threads and pass through, the inside and outside two sides of needle body is equipped with shallow slot, can hold No. 7 silk threads and hide, sewing needle is divided into 2cm, 2.5cm, three models of 3cm by chord length, and rustless steel is made.(Fig. 2)

The beneficial effects of the utility model are, returning line is convenient to slide through pin hole and is taken skin out of on another arching trajectory when sewing needle backstitches, and it is flexible to use pin; Two shallow slots in the interior outside of its needle body can hold suture to be hidden, and makes tissue injury slighter, and frictional force is littler, and it is easier to sew up; Sewing needle is divided into three models and is applicable to size, the pediatric patient that the girth of a garment is different respectively.

Fig. 2 is a tomograph of the present utility model, and wherein a is a front view, and b is a vertical view, and c is the needle body cutaway view.

Fig. 3 is this utility model operating procedure sketch when being applied to peritoneoscope hernical sac high ligation.

1. needle point among the figure, 2. backshank, 3. pin hole, 4. in shallow slot, 5. outer shallow slot, 6. skin, 7. interior collar extension.

The specific embodiment

Below in conjunction with accompanying drawing structure of the present utility model and use are described further.

Collar extension and surrounding structure thereof in seeing clearly under the peritoneoscope, the two sharp diplopore double flute circle curved suture needles of common needle holder clamping, suture silk is penetrated by an end pin hole, is passed by other end pin hole again.Sewing needle is thrust by interior collar extension body surface projection place and reaches outside the internal ring peritoneum, by the inboard of internal ring from up to down, again outwards by its below, sew up around internal ring, needle point pierces through skin on outwards having crossed behind deferent duct and the spermatic cord blood vessel, expose front end pin hole and suture, the end of a thread is unloaded by pin hole, needle holder clamping front end, adjust the afterbody needle point, sew up (backstitching), the backshank point is passed from former inserting needle hole take suture out of by its top, lateral of internal ring, mention the suture two ends and tie a knot in subcutaneous tissue, finish high ligation of hernial sac.(Fig. 3)
