Abstract
The utility model belongs to the field of medical instruments, particularly discloses an improved hard cystic duct microscope comprising an endoscope main body; the front end of the endoscope main body is a hard working end part; an ocular input end, a light source input end, an instrument passage, a water inlet passage and a water outlet passage are arranged on the endoscope main body; and the front end of the hard working end surface is a bent tip part with radian. The utility model can effectively solve the problem that since irregular physiological curve of a cystic duct body enables a conventional hard cystic duct microscope not to enter, calculus and polypus cannot be removed thoroughly through the gall bladder preservation and calculus and polypus removal operation. In the utility model, since the front end of the working end part has a certain angle, an endoscope can easily enter into a cystic duct for observation under the guide of the angle; and in addition, since the wide and big instrument passage is provided, the instrument can enter into the cystic duct for surgical treatment, and calculus and polypus are removed thoroughly, the recurrence rate is effectively reduced, and the cure rate of patients is improved.
Description
Technical field
This utility model belongs to field of medical appliances, and relate to modern medicine and carry out new-type scope Wicresoft and protect a kind of core medical instrument that gallbladder is got stone, got the polyp operation, specifically be a kind of improved hard gall bladder tube mirror.
Prior art
Existing guarantor's gallbladder is got hard gall bladder tube mirror used in the stone surgical apparatus, usually its work end is straight hard working portion, and because the cystic duct structure of human body is irregular bending, the straight hard working portion of hard gall bladder tube mirror will enter when observing in the cystic duct and treating, operative doctor needs the very fine scope of controlling, and damage may be caused to cystic duct in the hard work end that scope still unavoidably takes place, increase the difficulty and the safety coefficient of operation, operation is inconvenience very, and have influence on carrying out smoothly of operation, simultaneously it is difficult in and protects gallbladder and get stone (polyp) operation calculus and polyp are got clean problem, relapse rate is higher, has seriously influenced the healthy of sufferer.
Summary of the invention
The purpose of this utility model is the hard work of hard gall bladder tube mirror elder generation end is designed to have certain angle, to cooperate Choledochal physiological bending, has effectively prevented the first end of existing hard to Choledochal damage, and is safe and reliable; Front end have the first end of the hard gall bladder tube mirror of radian have the guiding gall bladder tube mirror enter Choledochal function, being convenient to gall bladder tube mirror enters in the cystic duct like a cork and observes, gall bladder tube mirror of the present utility model is simple in structure, easy to use, that Choledochal calculus, polyp can be removed is more thorough, improves the cure rate of sufferer.
In order to realize above-mentioned technical purpose, of the present utility model being achieved through the following technical solutions:
A kind of modified model hard gall bladder tube mirror described in the utility model, comprise the scope main body, described scope main body, the front end of described scope main body is hard work end, on the described scope main body eyepiece input is set, light source input, instrument channel, intake tunnel and exhalant canal, the front end of described hard work end is the forniciform first end that has radian.
As the further improvement of above-mentioned technology, the external diameter of described work end is 3～4mm, and length is 250～280mm, and front end 3～5mm place of its work end is for having forniciform first end, and its crooked angle is 10 °～45 °.
In this utility model, it is the hard material manufacturing that described front end has the work end of the hard gall bladder tube mirror of radian.
In this utility model, the input of described intake tunnel and exhalant canal designs the end in instrument channel respectively, stretch out to the left and right sides, and intake tunnel and exhalant canal all is communicated with instrument channel.
Specifically, the diameter of described operating walk way is 2.0mm.
In this utility model, the diameter of lens of described light source input optical system is 1.5mm.
Compared with prior art, the beneficial effects of the utility model are:
This utility model is owing to be designed to the first end of the hard work end of hard gall bladder tube mirror to have the bending section of certain crooked radian, the physiological bending degree that can cooperate cystic duct itself by this bending section preferably, effectively prevented the first end of existing hard to Choledochal damage, safe and reliable; Simultaneously this first end with crooked radian have the guiding gall bladder tube mirror enter Choledochal effect, be convenient to gall bladder tube mirror and enter like a cork in the cystic duct, observe; In addition, this utility model more has roomy instrument channel, and apparatus can enter the treatment that undergos surgery in the cystic duct, guarantees to perform the operation and fast carries out smoothly, and the calculus polyp is totally thoroughly clear, has lowered relapse rate effectively.
