Description
Technical field
The present invention relates to a kind of medical instruments, and in particular to a kind of adjusting elastic line looping and binding device.
Background technique
Hemorrhoid Loop ligature (also known as hemorrhoid plastic loop ligation art, hemorrhoid, which are inhaled, pricks art etc.) is the common method for treating hemorrhoid, curative effect
Definitely, principle is the root that special cushion rubber (such as rubber ring, latex circle, silica gel ring, elastic force coil etc.) set is tied in 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 a kind of making to cover the automation instrument that difficult to handle art becomes simple and easy, i.e., automatic hemorrhoid nearly ten years
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
Point is: simple and convenient for operation, accurate；One achievable operation, it is only 5~10 minutes time-consuming；And occur complication probability compared with
It is low；Patient does not need generally to anaesthetize, and pain is slight；Most patients do not need to be hospitalized yet, low in treatment cost.Existing issue is solution
Never any hemorrhoid illness of weight, lacks a kind of tool of executions surgical action that can efficiently coordinate, one, which improves operation, imitates
Rate and success rate, tracing it to its cause is to carry out including that positioning, absorption and set bundle of pathological tissues etc. are dynamic in surgical procedure
Make, to solve the above problems, applicant has applied for CN105997182A Chinese patent before, in the hope of solving the above problems, but
In the presence of structure is complicated, cause cost, medical expense higher.
Summary of the invention
