Description

Disposable hemorrhoid anastomat with transparent nail bin

Technical field

This utility model belongs to medical instruments field, specially refers to a kind of hemorrhoid anastomat with transparent nail bin.

Background technology

Hemorrhoid are a kind of commonly encountered diseases of surgery, and proverb has: the saying of ten male nine hemorrhoid, sickness rate are very high, account for 85% of all anal and intestinal diseases.About the cause of disease, from nineteen sixty, set up " anal canal blood vessel pad ", be called for short " anus pad theory ", thought that the anus pad is the ring-type taeniae telarum of the wide 1.5-2.0cm in human body anal canal internal tooth shape line top, this district is thick and soft, being the vascular liner of a height specialization, is the normal structure of human body, but owing to reasons such as diarrhoea, constipation, abdominal pressure increase, generation pathologic hypertrophy is referred to as hemorrhoid after moving down.Along with this conception of species is widely accepted, great changes have also taken place in its treatment means thereupon.Surgery branch of Chinese Medical Association analogy group had been worked out " hemorrhoid diagnosis tentative standard " in 2000, hemorrhoid was divided into the I-IV degree, 4 class, think III at present, in the IV degree, severe hemorrhoid must operative treatment, and is simultaneously with " mucosa ring cutting art on the hemorrhoid " (PPH operation), the most acceptable to all.This operation originates from the nineties in 20th century, and this surgical technic is meant 2-4cm place mucosa and tela submucosa on the excision pectinate line, makes the anus pad upwards move, and plays the effect of suspention anus pad, obviously alleviates the symptom of prolapsus.Simultaneously because the excision of submucous tissue is blocked the blood supply of superior rectal artery branch to the hemorrhoid district, the atrophy of postoperative hemorrhoid body.Advantages such as this operation is painless with its postoperative, anal incontinence simply, does not take place operation technique and the fashionable whole world, the success of this operation also are that hemorrhoid anus pad moves down theoretical excellence and annotates.The apparatus of its application the earliest be referred to as PPH, so this art formula is called " PPH art " again.

In market, implement this type of used product of performing the operation at present, all have not convenient during reasons such as the visual field, anus place is bad during owing to operation technique are used, even unsafe factor, so we are according to the demand of doctor's operation, design the PPH with transparent nail bin, this technology can improve the safety of operation greatly.

Summary of the invention

This utility model technical issues that need to address are, structure at the hemorrhoid anastomat that is using in mucosa ring cutting operation (PPH operation) apparatus on the hemorrhoid is improved, with preceding because of apparatus structure opaque, whether the doctor can't see organizing of this excision in operation and enters fully in the device body nail bin, can't judge whether that also its hetero-organization enters in the anastomat in addition, easily produce blindness, in order to overcome this defective, will redesign the structure of hemorrhoid anastomat, the purpose of this utility model is to provide a kind of hemorrhoid anastomat with transparent nail bin.

The purpose of this utility model relies on following technical scheme to realize, a kind of hemorrhoid anastomat with transparent nail bin, comprise the cone-shaped nail supporting base assembly and the pad cutter ring component that are positioned at hemorrhoid anastomat front end, be positioned at body of a gun assembly, the Handleset that is positioned at the rear portion and the adjusting nut parts at anastomat middle part, it is characterized in that, be close to above-mentioned pad cutter ring component nail bin, pushing slice of nail and three in nail bin cover afterwards and be positioned at body of a gun assembly part before, all adopt transparent material to make.Have the handle hole of a pair of increasing on the outer sleeve body of described nail bin cover.But at these handle hole place tool using pincers, even with the interstice that guarantees identical oral area closure, it is more safe and reliable to reach operation, avoids the generation of corresponding complication.

The beneficial effects of the utility model are, whether this hemorrhoid anastomat with transparent nail bin can make the operator clearly see the anastomotic stoma that enters the hemorrhoid anastomat whether fully of organizing of this excision, should not entering part get rid of, thereby guarantee that excision extension is accurately complete, performs the operation successfully.

The specific embodiment

With reference to Fig. 1-Fig. 3, the appearance and the internal structure sketch map of hemorrhoid anastomat in the expression PPH operation, 1 for being positioned at the nail supporting base assembly that hemorrhoid anastomat front portion is cone-shaped among the figure, thereafter immediately following pad cutter ring 2, nail bin 3, coupled pushing slice of nail 4 are inserted within the nail bin cover 5, at this, 3, what 4,5 three parts adopted is that novel transparent material is made, and what be positioned at the middle part is body of a gun assembly 6, its below is a flexible handle assembly 7, and hemorrhoid anastomat afterbody is an adjusting nut 8.Make the doctor in operation process, observe what of tissue that inside comprises more clearlyly, a pair of handle hole 5-1 on it is than the corresponding Kong Yaoda of product in the past, this is in order to use the Allis pincers, the interstice that guarantees identical oral area closure is even, to reach the purpose of operation safety and reliability.The doctor in use, at first less and anal plate three the slighter points that turn up clamp no wounds with three and fixedly strut in hemorrhoid piece prolapsus, circular anal canal dilator is enclosed within on the anorectal introducer is imported into together.After removing the anorectal introducer, the mucosa of prolapsus falls into the sleeve pipe of anus-expanding unit.Because nail bin cover part is transparent in the hemorrhoid anastomat, we can see through it and observe pectinate line.Import seam by anus-expanding unit and prick device, apart from the purse string suture line of finishing whole circle more than pectinate line 3-4 centimetre, suture only passes mucosa and tela submucosa.Circular hemorrhoid anastomat outward winding afterwards to maximum position.Import the hemorrhoid anastomat and make its nail supporting base by the anal canal dilator, then the purse wire knotting is fastened on the center-pole of anastomat deeply to the upper end of purse wire.With thread catcher the tail end of purse wire is pulled out from the side opening of hemorrhoid anastomat.To be dragged to the outer suture knotting of anastomat or fix by Clip Applier.The head of hemorrhoid anastomat is imported anal canal fully,,, use the Allis pincers, guarantee that the interstice of identical oral area closure is even Yi Bian appropriate tractive purse string suture line is inserted the mucous layer of prolapsus in the cavity of hemorrhoid anastomat head Yi Bian tighten up anastomat.Behind the complete closed anastomat, whether inspection is organized suitable, pulls the trigger and excise the prolapsus mucosa in the cavity again.

Claims (2)

1. hemorrhoid anastomat with transparent nail bin, comprise the cone-shaped nail supporting base assembly and the pad cutter ring component that are positioned at the anastomat front end, be positioned at body of a gun assembly, the Handleset that is positioned at the rear portion and the adjusting nut parts at anastomat middle part, it is characterized in that, be close to above-mentioned pad cutter ring component nail bin, pushing slice of nail and three in nail bin cover afterwards and be positioned at body of a gun assembly part before, all adopt transparent material to make.

2. according to the described hemorrhoid anastomat of claim 1, it is characterized in that, have the handle hole of a pair of increasing on the outer sleeve body of described nail bin cover with transparent nail bin.
