Description

The concealed separating knife of anal-surgery

Technical field

A kind of concealed separating knife of anal-surgery is the utility model is related to, belongs to the field of medical instrument technology.

Background technology

Constipation is divided into two big fundamental types：That is Colonic transit obstruction type and Treatment of Outlet Obstruction Type, both have jointly can be described as Mixed type.Anorec tal function causes the Treatment of Outlet Obstruction Type Constipation of excrement discharge obstacle clinically more common extremely, clinical Mainly characterized by intractable difficult defecation, defecation is laborious for performance, and defecation time extends, though or awareness of defecation it is frequent, each defecation Amount is few, has defecation to feel not to the utmost, difficulty is also discharged even if soft stool, need hand with anus bearing down, anus pain sense, some patients more Refer to and assist defecation.Its pathogenesis does not also illustrate completely, mental handicape, anatomical structure and physiological function change with it is outlet obstructed Type constipation has relation.

The Treatment of Outlet Obstruction Type Constipation cause of disease is complicated, and initiating agent is unknown, and Pelvic floor spasm can cause constipation, and constipation can cause directly Dash forward before intestines, Internal rectal mucosa prolapse, perineum decline, sacrum directly separates, splanchnoptosia etc..Another aspect encysted rectum, rectal mucosa Interior prolapsus, perineum decline, sacrum directly separates, splanchnoptosia etc. can also cause Treatment of Outlet Obstruction Type Constipation.Mutually influence, mutually promote Into.

The dysporia disease that wherein obstruction of basin bottom outlet is characterized caused by the spastic hypertrophy of puborectalis, again Claim Puborectalis syndrome.Pertinent literature reports that its incidence accounts for the 8.2% of constipation.When normal person is under quiescent condition, shame Bone rectum muscle is in contraction state, and this is of flaccid muscles during defecation, and so that excrement is discharged, during defecation, puborectalis is not only not Relaxation is shunk on the contrary, then will influence defecation.Puborectalis syndrome is to cause one of outlet obstructed common factors, and pubis is straight The long-term spasm of myenteron causes muscle fibre loose, and digital rectal examination can feel that anal canal tension force increases, and rectum coccyx angle is deepened, and pubis is straight Myenteron thickens.Patient is made to do defecation action, the anal orifice and rectal intestine ring that should be relaxed does not relax not only, on the contrary in contraction state, anal canal Rest pressure and systolic pressure increase when rectal pressure detects, anal canal length increase, up to 5-6cm.Defecography shows static, defecation phase Occur " shelf sign ".Gradual with symptom is aggravated, and will seriously affect the quality of life of patient, thus the sick prevention and treatment Widely paid attention to.

Small needle knife is a kind of miniature instrument of Traditional Chinese Medicine operation, and the knife of the pin of acupuncture therapy and operative treatment is combined into by it One, has the dual-use function that acupuncture is cut with knife, the damage very little to tissue.Small needle knife hook cuts the letter of spasm plumpness puborectalis Easy row, stenosis of anal canal of effectively having loosened, the anus right angle caused by correct for puborectalis spasm hyperplasia become larger, and increase defecation When angle, expand anal canal inlet calibre, so as to eliminate and alleviate obstruction, and it is open to effectively prevent big notch The surface of a wound, reduces the generation of postoperative complications, sequelae, meets the development trend of current minimally invasive surgery.But existing small needle knife, As CN2465666Y, CN200957103Y and CN2468438Y are disclosed, the knife hook on small needle knife be it is naked be exposed on the external, cutting convulsion The accidental injury of the rectal mucosa easily caused during contraction plumpness puborectalis.

The content of the invention

The purpose of this utility model is to provide a kind of rational in infrastructure, and when being not required to cutting operation, arc cutter head is hidden in shield In pipe, when cutting make arc cutter head move forward or rear move and stretch out pillar, will not damage tissue when separating mucous membrane, can effectively keep away The concealed separating knife of caused rectal mucosa is accidentally injured during spasm plumpness puborectalis anal-surgery is exempted to cut.

The utility model is that the technical solution for reaching above-mentioned purpose is：A kind of concealed separating knife of anal-surgery, it is special Sign is：Including knife bar, pillar and handle, the knife bar front portion is connected with recurvate arc cutter head, rear portion is connected with Push button, arc cutter head both sides are equipped with cutting edge；The pillar is the anterior hollow sleeve with curved arc position, pillar rear side and handle Connection, knife bar are arranged in pillar and handle and can move, and pillar front end is equipped with bulb, and pillar is arranged with out knife in arc portion Groove, arc cutter head during knife bar neutral position are located in the curved arc position of pillar, knife bar reach or rear move the curved arc for stretching out pillar Position goes out cutter groove, and the push button, which is installed at the limiting slot of handle, simultaneously can drive knife bar forwardly and rearwardly to be moved along limiting slot Dynamic, handle is equipped with the cavity for being used for placing spring in push button front and rear sides, and spring is arranged in the cavity of respective handle, spring One end is withstood on handle, the other end is withstood on push button.

The knife bar front portion of the concealed separating knife of the utility model is connected with recurvate arc cutter head, rear portion is connected with and pushes away Button, and sheath is connected with handle, therefore knife bar can be arranged in sheath and handle and can be in sheath and handle free axle forward After move, since pillar head for globulate, its rear portion is in curved arc position, cutter groove is arranged with out in arc portion, therefore in knife bar Arc cutter head during vertical position is located in the curved arc position of pillar, and arc cutter head automatic hidden is ensconced in pillar, can pass through pillar On bulb and recurvate curved arc position will not damage tissue in separation mucosal tissue, when needing to cut separation spasm fertilizer During thick puborectalis, only push button is promoted need to forward or promoted backward, arc cutter head is forward extended out or stretch out backward pillar Curved arc position, and appear cutter head, play dissection, effectively avoid caused straight when cutting spasm plumpness puborectalis The accidental injury of intestinal mucosa, it is rational in infrastructure, it is safe and reliable.
