Description
Technical field
The utility model relates to a kind of the field of medical instrument technology more particularly to a kind of automatic ejection retraction mechanisms of ring cutting.
Background technique
With the continuous improvement of people's living standards, people have higher requirement to own health and quality of life, packet
Too long skin is the common reproductive problems of male, and the male for receiving Wrapping annulus cuts operation is being increasing, and range is also from original
Young constantly to prolong to advanced age and low age expansion, Wrapping annulus cuts operation mainly uses following three kinds of modes at present:
One, traditional open surgery cuts off too long foreskin, art mouth with scissors and blade and other conventional surgical instruments
It being sutured with suture, operating time is long, doctor's heavy workload, the positioning of art mouth is nonstandard, operating time is long, amount of bleeding is big,
The art mouth scar of healing is big, postoperative pain, postoperative often hemotoncus, art mouth occur least smooth, it is difficult to which standardization carries out, at present base
This is eliminated；
Two, card for a long time is carried out to too long foreskin using various clamp-press type anastomat for circumcision to press, cause card splenium
Position ischemic necrosis and fall off, operating time is shorter than traditional operation, convenient and efficient, bleeding is few, but postoperative edema is serious, pain degree
High, art mouth healing is most slowly, institute must all be returned by suffering from takes ring, takes ring painful, child even wants to remove ring under secondary anesthesia, take
Art schistostoma opens probability height after ring, since oedema is serious, also leaves larger scar after the healing of art mouth, and occurs glans penis necrosis disease
Example, also just exits clinic gradually；
Three, it is performed the operation using Circumcision suturing device, such as number of patent application: 201210475409.X and patent application
Number: Circumcision suturing device disclosed in 201310266729.9, this operation make the best use of the advantages keeping away to first two operation substantially
It is short, but doctor's skilled operation degree is larger to operation influential effect, and bandage after operation is tighter, and urine often has obstructed sense, and wrapping is not
When appropriate, occur postoperative hematoma may, patient or some discomforts, suturing nail time that falls off are longer.
In the course of surgery, linkage can not be formed by existing between the component of each step passes the above Wrapping annulus cuts operation
It is dynamic, cause the convergence time between each step long, and problem that procedure efficiency low big to tissue damage.
Utility model content
For overcome the deficiencies in the prior art, one of the purpose of this utility model is to provide a kind of automatic ejection contracting of ring cutting
Mechanism is gone back to, Wrapping annulus cuts operation in the prior art is can solve and in the course of surgery, there is nothing between the component of each step
Method forms linkage transmission, causes the convergence time between each step long, and problem that procedure efficiency low big to tissue damage.
The purpose of this utility model adopts the following technical scheme that realization:
A kind of automatic ejection retraction mechanism of ring cutting, including glans penis seat, acrosome, driving mechanism, transmission mechanism, circular cutter and preceding
