Description

A kind of accurate seamless foreskin cutting assembly

Technical field

This utility model relates to medical instruments field, particularly to a kind of accurate seamless foreskin cutting assembly.

Background technology

Redundant prepuce phimosis is high at Asian countries's sickness rate, the harm of redundant prepuce: 1, foreskin encases glans penis for a long time so that glans penis becomes very sensitive, and sexual behaviour once occurs, and glans penis easily causes premature ejaculation due to very sensitive；2, easily cause male sterility, cause prostatitis owing to smegma infects, reduce motility of sperm and semen liquefied duration, can cause sterile；3, " smegma " during redundant prepuce, it is easily generated.Smegma appropriate bacterial grows, therefore can cause Glans penis and foreskin inflammation；4, redundant prepuce is major source and the key factor causing the cross infection repeatedly of men and women's reproductive disease；5, the stimulation of the dirt such as the antibacterial in long-term prepuce of penis, virus, epithelial cell of coming off, can make the morbidity chance of carcinoma of penis increase.So popular so in short at Urology Surgery: this thing of foreskin, sooner or later it is intended to cut.

In the posthetomy that China is traditional, artificial operation has the disadvantage that: 1, short time consumption is long, often cannot complete operation in local anaesthesia drug treating time, often half section after surgery, do second time anesthesia, the anesthesia of circumcision is suitable pain as everybody knows, so bringing many miseries to patient.2, amount of bleeding is many, tradition is peritomized needs cut-out Inner prepuce, inner panel contains substantial amounts of blood vessel and lymphatic vessel, and petechia needs conventional silk thread hemostasis by ligation, thus can leave over a large amount of the end of a thread on the inner panel of foreskin, owing to silk thread cannot absorb, this just brings many miseries in the future to patient, and therefore a lot of doctors can select to stop blooding with electric knife, but the coagulation of electric knife can damage more lymphatic capillary, in postoperative foreskin water, meeting especially severe, brings great misery to patient.3, due to the sensitivity that the foreskin at glans penis is suitable, so the even above operation of pain when taking out stitches.Partial Hospitals, in order to alleviate patient pain, can give local anesthesia when taking out stitches, so many hospitals can use expensive absorbable thread.

Many anastomats occur in clinical position in recent years, and be widely used in clinic, also material benefit is brought to extensive patients, its advantage is: 1, operating time is greatly shortened, common posthetomy probably needs 40-60 minute, and using anastomat, operating time shortens to 10-20 minute, can save the time of more than half part；2, amount of bleeding is few, the most several milliliters, and even major part blood loss volume during the operation is within 1 milliliter.3, alleviating patient pain, operating time is short, and patient can strive for before anesthetic action is in the past to ward or rest of going home.4, without taking out stitches, the nail of titanium alloy can start shedding off for about 1 week after surgery, within about 2 weeks, has come off.

Even if but in clinic, so still have disadvantages that needs go to improve: 1, current anastomat is in posthetomy, major part can be excised and originally held the inner panel of penis, this part inner panel is the most sensitive, it it is the important sources of pleasant sensation in Male sexual life, excise this part inner panel, the pleasant sensation of male can be reduced；2, needing the head end of foreskin to tie up on the holder cutting foreskin when, glans penis is enclosed in foreskin, does not sees the position of foreskin and glans penis, is often not easy to hold the length of excision；3, postoperative typically all no small cicatrix can be left at the foreskin on glans penis side, although wanting neat compared with traditional-handwork ring cutting cicatrix, but the postoperative meeting in the cicatrix some time of some patients is being erected or swelling, even subcutaneous fibrotic hamartoplasia after sexual life, brings no small misery to extensive patients；4, being close to the portion strap of glans penis owing to anastomat can excise, in frenulum, blood supply is enriched, especially glans penis and foreskin junction, and the petechia that this operation is main often often has the hemorrhage of activeness；5, cut-out Inner prepuce, damaged portion lymphatic capillary, cause obstruction of lymphatic return, swelling is obvious.

Summary of the invention

The purpose of this utility model is to provide a kind of accurate seamless foreskin cutting assembly, the modus operandi of its thorough posthetomy of overturning over, the inner panel of original glans penis exoperidium can be retained, allow the foreskin at glans penis keep ecosystem, and accomplish the accurate ring cutting effect without cicatrix.

The technical scheme in the invention for solving the technical problem is: a kind of accurate seamless foreskin cutting assembly, including outer cutting cannula and interior fixed sleeving, outer cutting cannula is placed on interior fixed sleeving, and with interior fixed sleeving clamping, interior fixed sleeving lower end has outward extending annular gear edge, annular gear is provided with blade pad in edge, interior fixed sleeving upper end is provided with threaded portion, circumferencial direction along interior fixed sleeving outer wall is provided with one group of positioning convex, and described interior fixed sleeving is shaped with the binding groove around its outer wall circumferencial direction near the one end on annular gear edge；

Described outer cutting cannula includes trocar sheath, annular blade and annular nail bin, annular nail bin is fixed on the lower end of trocar sheath, along the uniform some ejector pin bars of its circumferencial direction on annular blade outer wall, the inwall of annular nail seat is provided with the nail bin being slidingly fitted with ejector pin bar, the locating slot matched with positioning convex it is additionally provided with on the inwall of annular blade, the most fixed connecting shaft on the outer wall of annular blade, it is provided with between connecting shaft with ejector pin bar and is connected spring, the sidewall of trocar sheath offers slide slot, described connecting shaft through slide slot and with trocar sheath outside lifting drive structure be connected；

Described standard seamless foreskin cutting assembly also includes a nut, and when interior fixed sleeving stretches out in outer cutting cannula, nut is connected with threaded portion.

As preferred structure of the present utility model, described lifting drives structure to include fixed handle and the lifting handle being arranged on outside trocar sheath, one end downward bending of lifting handle is also flexibly connected with connecting shaft by connecting plate, and the bending place of lifting handle is hinged with the outer wall of trocar sheath.

Preferably, the front end of described lifting handle is also provided with offering the drive division of arcuate groove, and the tail end of lifting handle is provided with anti-skidding projection；It is additionally provided with safety block between fixed handle and lifting handle.

The beneficial effects of the utility model are:

(1) utilizing this utility model to excise and be positioned at radix penis part, i.e. penis is with the foreskin outside plate at scrotum and stomach wall, owing to the outside plate of foreskin is the most poor, seldom has big blood vessel and neural and lymphatic capillary, and this makes the swelling of postoperative foreskin significantly alleviate；Next remains the inner panel around Substance P glans penis the most widely so that postoperative life quality is protected, and the cicatrix at excision position can be hidden in pubes after pubes are longer, it is possible to accomplish accurate seamless；Dividing a word with a hyphen at the end of a line at radix penis part penis frenulum swells in " cicatrix " line sample of surface, and its internal contained blood vessel, neural to lack much compared with glans penis lower end, postoperative hemorrhage amount is few.

(2) during operation, owing to interior fixed sleeving and outer cutting cannula are all enclosed within penis, penis head stretches out interior fixed sleeving, when fixing foreskin outside plate, can observe the length needing to excise foreskin intuitively；Safety is high.
