Abstract
The invention discloses a magnetic ring type prepuce anastomat. The magnetic ring type prepuce anastomat comprises an upper magnetic ring shell and a lower magnetic ring shell, an upper magnetic ring and a lower magnetic ring are fixedly embedded into cavities of the upper magnetic ring shell and the lower magnetic ring shell respectively and are jointed together under attracting magnetic force of the upper magnetic ring and the lower magnetic ring, jointed pressing surfaces of the upper and lower magnetic ring shells are rough surfaces respectively, and a plurality of disconnected grooves which are arranged at intervals are formed in one or two of the jointed pressing surfaces of the upper and lower magnetic ring shells and are arranged along the direction of being communicated with the outer and inner sides of the corresponding jointed pressing surfaces. The magnetic ring type prepuce anastomat is simple in structure and convenient to operate and can be used for circumcision conveniently; smooth and safe prepuce pressing and excision can be achieved during operation under the condition that pressing force can be guaranteed.
Description
Technical field
The present invention relates to a kind of new type medical equipment, particularly a kind of male's foreskin cuts special foreskin magnet ring anastomat.
Background technology
Redundant prepuce or phimosis are the common diseases of Urology Surgery, redundant prepuce or phimosis easily cause maldevelopment of penis, even damage the function of human kidney, the easy inflammation of patient's penis of redundant prepuce, cause urethral orifice or anterior urethra to occur narrow, cause the difficulty of urinating.Traditional circumcision carries out excision by surgical knife tool, laser homenergic apparatus.Current clinical practice more special anastomat surely belongs to " quotient ring ", its patent CN1919152A and patent CN264913Y is the typical apply of this class patent, it is extruded prepuce tissues by an internal ring and outer shroud, causes being extruded Tissue approximation necrosis healing.Patent CN104490455A adopts the structure of inner and outer ring equally, and profile of tooth cutting knife is housed inside outer shroud, can fast shut-off tissue.Patent CN1463677A is also a kind of dicyclic prepuce remover, and by being pressed between Internal and external cycle by embedding for foreskin redundance, distally foreskin ischemic necrosis, near-end preputial heals gradually.Such inside and outside ring structure is wrapped in foreskin due to internal ring, and foreskin cutting is in the outside of internal ring, and still has residual prepuce tissues outside internal ring between foreskin cut place to foreskin root, and hands speed is excised still clean not.
Patent CN201210497584.9 adopts the form of suturing nail to perform the operation, and sews up after prepuce tissues ring cutting.The method of such suturing nail is hemorrhage because suturing nail causes, postoperative easily causes inflammation, and suturing nail such as should not to come off at the defect, is unfavorable for actual clinical operation.By suture after the cutting such as traditional scalpel, electric knife, laser scalpel, avoid the defect of suturing nail, but operation is complicated, and operating time is long, requires higher to the operant level of operation.
Magnet ring incision principle be utilize high magnetic material to make magnet ring between strong captivation, produce persistence, non-penetrative, magnetic force reduce and the mechanical pressure power strengthened gradually with two magnet ring spacing.Utilize two magnet rings that are identical or similar shape to be placed on penis, two magnet rings carry out precisely involutory along penile shaft to automatically involutory characteristic, the prepuce tissues ischemic necrosis of pressurized between two magnet rings, and inside magnet ring, prepuce tissues heals automatically simultaneously.At present, magnetic Technology in Pressing is mainly used in the various traditional operations such as the treatment of postoperative biliary tract stenosis, coronary artery bypass grafting, esophageal stricture treatment, vascular anastomosis, gastrointestinal anastomosis and endoscope-assistant surgery.Magnet ring anastomosis is for traditional titanium nail anastomat, not hemorrhage in its art, within postoperative several days, magnet ring comes off, can take off smoothly from penis, wound healing place does not leave over any object, simultaneously wound healing is more desirable, postoperatively should not infect, thus becomes the ideal chose of the operations such as anorectal, gastrointestinal and foreskin.
At present, all research and development design is carried out to magnet ring anastomosis and magnet ring stapling apparatus both at home and abroad.Patent 201010200289.3 is launched mainly for gastrointestinal anastomosis device, and such dress that coincide is only suitable for the end to end anastomosis of intestinal, blood vessel, cannot operate for prepuce of penis operation.Patent 201210000963, by improvement magnet ring, can facilitate magnet ring to excrete by magnet ring distortion.The magnet ring anastomat of patent 20140699112.0 fixes two magnet rings by buckle.Above magnet ring apparatus is mainly for anastomosis operations such as gastrointestinal, anorectal, blood vessels, also inapplicable for circumcision.
Patent 201510382795.1 carries out squeezing cutting by utilizing the involutory prepuce tissues of carrying out of upper and lower two magnet rings, the circumcision time can be shortened well, but, its squeezing face is difficult to ensure prepuce tissues slippage, and the very difficult control of postoperative Inner prepuce length is longer than inner panel, its structure needs into improvement and optimization.
Authorization Notice No. is that the Chinese patent of CN102018551B discloses " a kind of prepuce ring-cutter ", it comprises internal magnetic ring and outer magnetic ring, internal magnetic ring is coaxial and magnetic is attracting with outer magnetic ring, the matching surface of internal magnetic ring and outer magnetic ring is close to penis, form passivity compressing to foreskin, described internal magnetic ring and outer magnetic ring are coated with a clad.But magnet ring appearance adopts one to have elastic silica-gel coating or plastic coating, cause squeezing to compress dynamics not in the face of prepuce tissues, prepuce tissues slippage may be caused; Meanwhile, the material of magnet ring can only choose some non-brittle magnetic materials, and for permanent-magnet materials neodymium iron boron the most conventional at present, its fragility is high, poor mechanical property, and iff interpolation coating, magnet ring easily ruptures; Magnet ring squeezing face does not consider that healing place Tissue Blood is for not enough, is unfavorable for the problem of organization healing and post-operative recovery; Foreskin healing time needs more than several days, and two magnet rings, at intra-operative, owing to not having anti-drop device, are easily subject to the interference of external force and throw off, causing operative failure; Squeezing face due to magnet ring is plane squeezing, and its structure and shape are difficult to the length ensureing and regulate the rear preputial of squeezing, meanwhile, is difficult to ensure that frenulum of prepuce retains the length longer than foreskin after surgery.
Cut off foreskin by the squeezing of magnet ring magnetic force, the operation of circumcision will be greatly simplified, reduce patient suffering, save patient's recovery time.For foreskin cutting operation, reduce operation difficulty of implementation, improving the basic method of operation comfort to be exactly the coinciding machine developing a set of handy practicality.Improving the operative effect of patient and increasing the operability of doctor, ensure that foreskin cutting operation is implemented smoothly.
Summary of the invention
The object of the invention is to the deficiency overcoming prior art, the foreskin magnet ring anastomat that a kind of structure is simple, operability is good is provided.
In order to achieve the above object, the technical solution used in the present invention is:
