Description

A kind of electro-surgical treatment device for rectal prolapse
Technical field
The present invention relates to anorectal surgery instrument more particularly to a kind of electro-surgical treatment devices for rectal prolapse.
Background technique
Rectal prolapse refers to that rectum wall part or holostrome shift downwards, and according to the diagnostic criteria of rectal prolapse, rectum is de- Following situation a: type: incomplete rectal prolapse, i.e. prolapse of rectal mucosa can be divided by hanging down；Show as mucous membrane of rectum layer abjection anus Outdoors, emersion object is hemispherical, the visible cricoid mucous membrane ditch centered on rectal cavity in surface；Two types: completeness rectum is de- It hangs down, i.e., rectum holostrome prolapses；For the rectum of prolapsus in cone, abjection part can be centered on rectal cavity in the glutinous of concentric arrays Film annular ditch；It is the intestines intussusception in ampullar recti that two types, which are divided into three degree: I degree according to prolapsus degree, i.e., recessive rectal prolapse；Defecation Radiography is in umbrella shade；II degree is prolapsed for rectum holostrome in outside anus, and anal canal position is normal, and anal sphincter function is normal, no With fecal incontinence；III degree emerges in outside anus for rectum and part sigmoid colon and anal canal, and anal sphincter function is impaired, companion There are the infull property of anus or total incontinence, is studied in recent years by the entembole theory to rectal prolapse, adult type rectum Prolapsus treatment is mostly based on operation.
Currently, a kind of using mucous membrane circular resection anus pad in stapler hemorrhoid for having in the surgical intervention mode of rectal prolapse The operation method of suspension has used a kind of PPH surgical instrument, the mechanism of the operation in the operation method are as follows: in prolapsus internal piles Top, the mucous membrane and submucosa tissue of the local circular resection lower rectum intestinal wall of nearly internal piles upper limb, and while excision Far and near end mucous membrane is carried out it is identical, make prolapsus internal piles and mucous membrane suspended in midair and pulled upwards, no longer prolapse；It is used in the operation It is disposable Anus piles anastomat to surgical instrument, for being repaired to prolapse of rectal mucosa in anal canal or hemorrhoid mucosal tissue stitching Multiple, which is made of product resist-nailed seat component, stapler body and attachment, in surgical procedure, first hemorrhoid block prolapse compared with Less and anal plate three points turning up slighter strut hurtless measure pincers fixation with three, and expander seat and interior guide sleeve are imported, hemorrhoid are made Prolapsus or mucous membrane of anal canal prolapsed portion reset, and after extracting interior guide sleeve out, the mucous membrane of prolapsus is fallen into the sleeve of expander seat, then is passed through Stitching devices suture the mucous membrane tissue of prolapsus in the sleeve of expander seat, will be glutinous in sleeve finally by stapler Membrane tissue excision, which includes multiple attachmentes, complicated for operation, extends operating time.
It uses in addition, traditional stitching devices are hold by doctor with needle forceps since sewing needle sutures, for straight Enteral prolapses, and mucous membrane is extremely inconvenient, and the mucous membrane to prolapse in surgical procedure is easy to interfere the progress of sewing work.

Step 2: the hand that operative doctor holds outer bush 1 stops being inserted into and remaining stationary, and another hand push moves draw back plate 217 to pushing away Pulling plate 217 is bonded with pull ring 215, and rotary-cut component 3 is pushed into highest point under the promotion of adjusting sleeve pipe 303 by mandril 302 at this time, this When the mucous membrane that prolapses fall under gravity between 202 top of suture casing and rotary-cut component 3 (Fig. 5)；
Step 4: pull downward on draw back plate 217, mandril 302 under the pulling force of adjusting sleeve pipe 303 by rotary-cut component 3 pull downward on to The mucous membrane sutured between 202 top of casing and rotary-cut component 3 is clamped (figure by certain position (size according to prolapsus mucous membrane) 6) draw back plate 217, is unclamped；
Step 5: pull ring 215 is pulled downward on, suture casing 202 drives suture casing pedestal 203 to move down under a stretching force, The suture drive rod 208 being fixed on suture casing pedestal 203 moves down therewith, hinged 209 band of connecting rod with suture drive rod 208 The dynamic sewing needle 212 for being fixed on 20 other end of connecting rod moves in a circle around needle guard 211, when the suture introducing needle connecting with sewing needle 212 213 pass through mucous membrane tissue insertion snap lock needle 204 when, stop drag pull ring 215(Fig. 7)；
Step 6: pushing up pull ring 215 to initial position, sewing needle 212 is retracted into original position, at this time suture introducing needle 213 and sewing needle 212 are detached from, and suture introducing needle 213 stays in snap lock needle 204 (Fig. 8) under the action of anticreep tooth 2133, and the end b of suture is drawn Tightly, suture is made to knot；
Step 7: opening rotary-cut start button 5, peeling knife is stretched out by 301 lower end of shell, and rotates the mucous membrane tissue of excision prolapsus (Fig. 9)；
Step 8: after the completion of excision, closing rotary-cut start button 5, peeling knife is retracted to 301 inside (Figure 10) of shell；
Step 9: twisting rotation step 207 moves down inner sleeve 201 relative to outer bush 1, at this time 201 top of inner sleeve Certain accommodating chamber is formed between outer bush 1, removed mucosal tissue is accumulated in accommodating chamber (Figure 11), pulls downward on outer Guide sleeve 1 removes whole device out of enteric cavity, and resection operation is completed when initial.
Further, the state diagram of suture 8 is as shown in Figure 12,13,14 and 15 in step 6 sewing process, initially When state, the end a of the suture 8 is fixed on the threading hole 2134 of suture introducing needle 213, the end b of the suture 8 by respectively by Suture casing 202 cavity and venthole 206 be pierced by, it is a, b section described between be provided with slip-knot, when the end a is pierced by from slip-knot, B is pulled tightly to hold and can knot, the slip-knot is stuck in the cable clamping interface 2041 of snap lock needle 204, institute in Figure 12,13,14 and 15 The slip-knot shown is one embodiment of the present invention, any to can be realized by the way that the end a to be pierced by from slip-knot, and b is pulled tightly to hold The slip-knot structure to knot all belongs to the scope of protection of the present invention.
Finally, it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although Present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: it still may be used To modify to technical solution documented by previous embodiment, or some or all of the technical features are equal Replacement；And these are modified or replaceed, technical solution of the embodiment of the present invention that it does not separate the essence of the corresponding technical solution.
