Description

A kind of prepuce cutting stitching instrument with anticreep propulsion system

Technical field

It the utility model is related to a kind of medicine equipment, and in particular to a kind of foreskin cutting suture with anticreep propulsion system Device.

Background technology

Circumcision operation at present has various ways, including the operation of traditional ring cutting, clinic of this operation method to doctor Skill requirement is high, and operation is cumbersome, time length, careless slightly to will result in Massive Bleeding, incision out-of-flatness, and wound suture is not beautiful See, postoperative dressing and take out stitches also pretty troublesome.Laser or electrotomy often occur that foreskin burns, post-operative recovery time length, The occurrence rate of hematoma is high.Foreskin is allowed because ischemic necrosis self falling by the ligation of small apparatus.During this operation method post-operative recovery Between it is long, need to utensil for a period of time, live inconvenience, be also easy to produce complication.In recent years there is the bag with anticreep propulsion system Skin stapler, although the existing prepuce cutting stitching instrument with anticreep propulsion system completes excision and suture simultaneously, The advantages that operating time is short, and bleeding is few.But it is not mature enough because the production development time is short, also exist in structure etc. a lot Defect.It is mainly reflected in overall structure and each parts fit structure sets unreasonable, complex process etc..If blade is with independence Split component form be installed on by assembling mode on corresponding pushing slice of nail, it is possible to cause in installation process askew Tiltedly, not just, the problems such as not prison welding, deflection when causing to perform the operation, knife is taken off, or even the risk of suture can not be cut off.And existing blade Pushing slice of nail bottom that is longer and being arranged on, visual poor, operator can not see cutting tissue site clearly, often cut by mistake The frenulum position of foreskin, increase operation risk.Nail bin is assembled into nail bin groupware with nail storehouse sleeve, and its main function is to accommodate prepackage Anastomosis staple.Require that anastomosis staple quantity is complete in operation.If neglected loading phenomenon, neglected loading position is easily oozed after it has been gathered Blood, influence surgical effect.Existing nail bin groupware is opaque material, result in and examines workload very to anastomosis staple neglected loading Greatly, efficiency is low.Identical nail tip push nail storehouse need to also be needed anastomosis staple being pushed into nail bin bottom after having inspected, examined when examining It is low to test efficiency, operation risk is big.

Utility model content

The purpose of this utility model is to be directed to above-mentioned the shortcomings of the prior art, there is provided one kind has anticreep propulsion system Prepuce cutting stitching instrument.This has the prepuce cutting stitching instrument of anticreep propulsion system simple in construction, science, reasonable, product work Skill is simple, it is simple to install and use, conveniently.

There is prepuce cutting stitching instrument of anticreep propulsion system to include resist-nailed seat component for this, nail bin, nail storehouse sleeve, suturing nail, It is connected to the boost motor of the nail storehouse sleeve, the boost motor includes operation handle, guider and is connected with resist-nailed seat component Screw thread turn-knob, corresponding one end of the screw thread turn-knob are provided with the extension for being connected to guide cylinder, and the extension is provided with an anticreep Go out device.

Institute's Anti-extrusion device includes stating ring on the extension perisporium of screw thread turn-knob, with corresponding guide cylinder located at described The ring groove of the corresponding connection of shape convex body.

The screw thread turn-knob is located at outside the free end of guide cylinder, by the annular convex of its ring groove and guide cylinder with leading To cylinder activity clamping.

The Anti-extrusion device include located at the resist-nailed seat component connecting rod thread rod part by posterior segment, with Circular bar portion corresponding to the screw thread turn-knob.

The suturing nail includes main part, and one end of the main part is coated with some antimicrobial coatings.

This has the prepuce cutting stitching instrument of anticreep propulsion system because nail storehouse sleeve, nail bin, ejector pin body etc. are transparent, sight Preferably, blade is in 0.5-1.5cm, both safety, again can whole observation cutter device action process, help to hold and control hand The implementation of art, improves checkability.Inseparable integral structure design is made in blade and ejector pin seat or pushing slice of nail, avoids scalding It is crooked during knife, it is not positive the problems such as, so as to reach in surgical procedure suture with cutting off unnecessary foreskin and visual perfect adaptation.It is special It is not and blade set location and scientific structure, rationally, makes do not have backlash during blade work, without unnecessary action, cutting Action process is clear-cut, agile, accurate.Its glans penis set has more compatibility by high-quality plastics product.
