Definitely, principle is that special cushion rubber (such as rubber ring, latex circle, silica gel ring, elastic force coil etc.) set is tied in the root of internal piles
Portion's (or basal part) takes this to block hemorrhoid blood supply using the elastic recovery force of cushion rubber, is allowed to necrosis, atrophy, falls off, to reach
Cure purpose.
It is previously extremely simple and crude for implementing the traditional instruments of the difficult to handle art of set, when operating cost, arduously, it is easy to happen complication.
To change this situation, occur nearly ten years it is a kind of make set prick the hand art become simple and practicable automation instrument, i.e., automatic hemorrhoid
Sore looping and binding device (also known as repeating type haemorrhoids ligation apparatus, continuous hemorrhoid suction ligation device etc.).It carries out covering the excellent of difficult to handle art using the instrument
Putting is：It is easy to operate, quick, accurate；One can complete to perform the operation, and take only 5~10 minutes；And occur complication probability compared with
It is low；Patient need not generally anaesthetize, and pain is slight；Most patients need not also be hospitalized, low in treatment cost.
Applicant applies on June 28th, 2016 and obtains " the automatic receipts of looping and binding device authorized on April 12nd, 2017
In the self-tightening type elastic thread looping and binding device proposed in tight elastic thread setting method and self-tightening type elastic thread looping and binding device " patent of invention,
It needs to carry out at least five operations during carrying out elastic thread and binding tissue, is to press down on reset key respectively, makes institute
It states gun body inner tube and moves forward to initial position with respect to gun body, gun barrel is installed to gun body, then be pulled to by manual self-tightening key
The minimum of contraction stroke end of adjustable spring, presses dislocation button, makes the gun body inner tube that the relatively outer gun barrel of interior gun barrel be driven to occur
Displacement, elastic force coil slide doubling-up set organizationally from interior barrel muzzle, finally detain Self-tightened spanner, make bracing wire automated attachment
Elastic thread is tensed backward under the drive of adjustable spring restoring force, to make the ring set aperture of elastic force line front end be contracted to rapidly
Minimum-value aperture and close to zero, and then realize and the set that destination organization more fastens is pricked, aforesaid operations are relatively complicated, increase hand
The complexity of art operation and it is necessary to be operated in the order described above, otherwise can not complete replacement and the binding work of elastic thread
Make.
