Description

Looping and binding device

Technical field

The utility model relates to medical device technologies, more particularly to a kind of elastica 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, is treated Effect is definite, and principle is root (or the base that special cushion rubber (such as rubber ring, latex circle, silica gel ring etc.) set is tied in internal piles Bottom), take this to block hemorrhoid blood supply using the elastic recovery force of cushion rubber, is allowed to necrosis, atrophy, falls off, to reach healing mesh 's.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 to cover the automation instrument that difficult to handle art becomes simple and easy, i.e. automatic hemorrhoid set is pricked Device (also known as repeating type haemorrhoids ligation apparatus, continuous hemorrhoid suction ligation device etc.).Carrying out the advantages of covering difficult to handle art using the instrument is: behaviour It is easy, quick, accurate to make；One achievable operation, it is only 5~10 minutes time-consuming；The probability that complication occurs is lower；Patient is general It does not need to anaesthetize, pain is slight；Most patients do not need to be hospitalized yet, low in treatment cost.

China's authorization utility model patent (ZL200820051521.X) discloses a kind of continuous hemorrhoid suction ligation device, including Ontology, further include set on ontology front end tube body and be successively placed on tube body multiple cushion rubbers being stretched, be placed in after tube body and The vacuum suction connector communicated with tube cavity, the cushion rubber device for ejecting on ontology, the tube body front end is cased with and tube body The emitting head of inner cavity connection, the cushion rubber are placed on emitting head；The cushion rubber device for ejecting includes at least one draught line and sets It is wrapped on bobbin winder device in the front end of intrinsic bobbin winder device, the draught line, the tail end of the draught line passes through tube body It is interior and be connected with the cushion rubber by traction mechanism via emitting head nozzle fold back, and along emitting head outer wall.

Above-mentioned hemorrhoid suction and ligature device (also known as haemorrhoids ligation apparatus) and both at home and abroad other kinds of haemorrhoids ligation apparatus, there is one Common feature, i.e., they be all made of " cushion rubber " as set and be tied in the basic material of hemorrhoid root；And it makes the cushion rubber and can be selected Raw material include natural rubber, latex or silica gel etc..

The clinical efficacy of hemorrhoid plastic loop ligation art and " internal orifice dimension of cushion rubber " and " elastic recovery force of cushion rubber " two technologies Index is directly related.And using cushion rubber as set prick material have the shortcomings that it is some intrinsic: 1. due to natural rubber (or latex, Silica gel etc.) inherent characteristic, the internal orifice dimension for limiting cushion rubber cannot be infinitely small, and 2.0~2.5mm generally can only be made (at least not Obtain and be less than 1.5mm), otherwise set is pricked easily is broken when stretching.This means that (is at least not less than in 2.0~2.5mm of diameter In size range 1.5mm), the hemorrhoidal tissue that quilt cover is pricked is by the effect not by any elastic recovery force, final tissue necrosis The ulcer range formed after falling off is also in 2.0~2.5mm (being at least not less than 1.5mm) left and right；2. when cushion rubber is pacified with tensional state When on looping and binding device, as time went on, it is easy that gradually fatigue occurs and internal orifice dimension is made to become larger；3. climate, environment etc. because Element influences, and cushion rubber is easy that aging occurs at any time, so that elastic recovery force be made to die down.

Due to the influence of factors above, it would be possible to lead to following consequence: 1. the postoperative cushion rubber that occurs in a short time slips, and causes to control Treat failure；2. causing postoperative hemorrhage complication (according to statistics, the postoperative Bleeding rate of hemorrhoid plastic loop ligation is 2%~5%)；3. hemorrhoid block Downright bad incomplete, ulcer surface healing delay affects the treatment.
