Abstract

The utility model relates to a purse-string device for surgeries, in particular to a puncture purse-string device belonging to medical equipment. The utility model is characterized in that: a retention puncture is arranged on the body of the cone-shaped purse-string device, the end of which is provided with a feed-through collar with thread. In the course of purse-string suture, the operator punctures the hemorrhoids and puts thread in them, thus ensuring that no hemorrhoids are left out and that the suture is done safely and fast without any damage to the muscular layer of the anal canal. Besides, because all of the hemorrhoids will be excised as pathological tissues, so purse-string suture by the way of puncturing will not cause any adverse effect.

Description

Thorn awl pouching device

Technical field

This utility model relates to a kind of purse-string suture device that is used for surgery, and particularly a kind of thorn awl pouching device belongs to technical field of medical instruments.

Technical background

People were to the history in surplus the understanding of hemorrhoid existing 4000 year, and for a long time, the theory of relevant hemorrhoid emerges in an endless stream.Since 18th century, hemorrhoid are considered to rectum lower end or anal canal and have abundant venous plexus, if at a place or the number place expansion or varicose take place, promptly become hemorrhoid, that is hemorrhoid are the vein groups of giving prominence to, be the vascular lesion that a variety of causes causes.Since the seventies in 20th century, the research of hemorrhoid has been obtained breakthrough, anatomy, histology and physiological discovery give hemorrhoid and have given modern notion.Thomson proposed first in 1975, and " hemorrhoid are normal anatomical structures that everybody all has, and at the lip shape wart or the title anus pad (anal cushions) of rectum lower end, the pathology hypertrophy of anus pad is the hemorrhoid disease." this new notion is subjected to Alexander-williams (1982), Bernstein (1983) and Melzier famous scholars' such as (1984) support.The external anorectal disease of publishing is recently learned the new ideas that extensively adopted hemorrhoid in the monograph, in the past few years also gains recognition gradually in China anorectal surgical educational circles nearly 10.The traditional method of internal hemorrhoid treatment, all be to treat at hemorrhoid itself comprise that injection of sclerosing agent, rubber snare are pricked and various forms of excision arts etc., is intended to make blood stasis to dwindle or disappears.In the surgical operation of the hemorrhoid excision of rising in recent years, a kind of PPH of being called operation method is arranged, i.e. mucosa ring cutting art on the hemorrhoid under the help of tubular anastomat.Its principle is: organize under the situation at reservation anus pad, with mucosa, the about 3-4cm of submucosa tissue circular resection on part internal hemorrhoid and the hemorrhoid, two ends simultaneously coincide, in blocking-up hemorrhoid supply vascular flow, the tissue that reaches slippage upwards suspends fixed purpose in midair, with the anorectal region of pathological state, return to normal anatomic status.Advantages such as utilization PPH art treatment severe hemorrhoids has the postoperative pain of alleviating, reduces postoperative hemorrhage, shortens the hospital stays, accelerates recovery period, do not influence daily life, relapse rate is low.The whole surgery process only needs 8-15 minute, and operation back patient does not almost have the sensation of pain.Owing to solved the root that hemorrhoid take place in the operation process, so reach the long-term effect ideal in the recent period.With the very thorny hemorrhoid of traditional remedies, as mixed hemorrhoid, ring-type hemorrhoid, serious prolapse of hemorrhoid, proctoptosis etc., the PPH operation has unique good efficacy equally to some.

But the technical ability of this operation is only grasped in some veteran surgeon's handss now, the reason that influences its popularization is a lot, some reason is because existing apparatus exists some defectives, makes operation complicated loaded down with trivial details, so the doctor who lacks experience is difficult for grasping.Operation has a process of pricking pocket, adopts traditional manual needlework sewing method, and operation is wasted time and energy, and easily suture needle thrust too dark, damage anal canal flesh layer, the while might be omitted pathological tissue.

Summary of the invention

The purpose of this utility model is to overcome the above problem that prior art exists, and a kind of thorn awl pouching device is provided.

The purpose of this utility model realizes by following technical solution:

Thorn awl pouching device, it includes taper pouching device body, wherein: be provided with the anticreep thorn on taper pouching device body, be provided with feed-through collar at the afterbody of pouching device body, be connected with lead-in wire on the feed-through collar.

The purpose of this utility model also can further realize by following technical measures:

Above-mentioned thorn awl pouching device, wherein, described anticreep thorn is barb.

Further, above-mentioned thorn awl pouching device, wherein, described anticreep thorn is one group or many groups.

Again further, above-mentioned thorn awl pouching device wherein, between the described anticreep thorn is and column distribution or spaced apart.

Advantage of the present utility model is: by in pricking the process of pocket, the operation implementer pierces through one by one to all hemorrhoid, and leaded company goes out, and can not occur the omission to hemorrhoid when having guaranteed to prick pocket.And, fast and safely, can not damage anal canal flesh layer, can not omit pathological tissue.Simultaneously, because all hemorrhoid will excise as pathological tissue, so one-side dependence is pierced through and pricked pocket and can not produce harmful effect.

The purpose of this utility model, advantage and characteristics will illustrate by the non-limitative illustration of following preferential embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.

Description of drawings

Fig. 1 is this utility model overall structure sketch map.

Among the figure: 1-taper pouching device body; The 2-barb; The 3-feed-through collar; The 4-lead-in wire.

The specific embodiment

Thorn awl pouching device as shown in Figure 1, it includes taper pouching device body 1, wherein: be provided with the anticreep thorn on taper pouching device body 1, be provided with feed-through collar 3 at the afterbody of pouching device body, be connected with lead-in wire 4 on it.For the bundle pocket effect of realizing ideal, described anticreep thorn is barb 2, and it is one group or many groups.And anticreep stings the arranged side by side or interval of range distribution between every group.In the operation implementation process, the operation implementer will sting the awl pouching device and vertically pierce through hemorrhoid, rely on thorn awl pouching device body to be provided with the anticreep thorn, and particularly the barb that adopts of anticreep thorn designs, and effectively prevent getting loose of the hemorrhoid that are pierced.Because barb 2 is one group or many groups, and the range distribution between 2 every groups of barbs equates or at interval.Like this, all hemorrhoid that are pierced secondary all can not occur and get loose.According to this step, the operation implementer can fast and accurately pierce through remaining hemorrhoid.Subsequently, on feed-through collar 3, be connected with lead-in wire 4, draw in the Binding Instrument cavity, be fixed to a suitable position, prepare the excision that coincide by tension.By in pricking the process of pocket, the operation implementer pierces through one by one to all hemorrhoid, and leaded 4 connect, and can not occur the omission to hemorrhoid when having guaranteed to prick pocket.Simultaneously because all hemorrhoid will excise as pathological tissue, so one-sided rely on to pierce through prick pocket and can not produce harmful effect.

In addition to the implementation, this utility model can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in this utility model scope required for protection.
