Description

Multi-functional biopsy pincers

One, technical field

The present invention relates to a kind of medical apparatus and instruments, especially a kind of multi-functional biopsy pincers.

Two, background technology

Endoscope is mainly as the intravital indirect observation of patient inspection, when needing for suspicious part that further inspection is confirmed, often need get into from endoscope channel with biopsy forceps and take off a spot of biological tissue in this position in patient's cavity and do the pathology cut sections for microscopic examination.

In the prior art, when medical steel biopsy forceps is got pincers alive in inspection,, can't know the definite position of focus, causing the sampling error easily, and then causing doctor's mistaken diagnosis owing to be the external auxiliary light-illuminating.

Three, summary of the invention

The objective of the invention is to solve the deficiency of above-mentioned existing biopsy forceps, a kind of multi-functional biopsy pincers are provided, make it have characteristics such as simple to operation, reliable, flexibly movable and good operation effect.

The objective of the invention is to adopt following scheme to realize: a kind of multi-functional biopsy pincers; It comprises clamp, clamp holder, conduit, operating grip and operating control device, is characterized in: it also comprises supervising device of being made up of object lens, optical fibers, eyepiece, CCD optical interface and the illuminator of being made up of light source, power line, switch, socket; Said conduit is made up of pipe in resin outer tube and the resin; Said switch and socket are used to control light source works, and light source is connected with socket, switch through the power line that passes the resin outer tube; But said clamp is made up of the hollow structure binding clip of the bullet-shaped of two correspondence foldings, and moves forward and backward the realization folding through a clamp interlock pipe in the pipe in the resin; The handle bar of said operating grip is end sealing; The hollow structure that one end is got through; Intracavity has fixing fibre-optic fixed leg in it, and said optical fibers one end is positioned at the focus point of eyepiece, and the other end passes the focus point that gets in the binding clip behind the clamp interlock pipe and be positioned at object lens; On the handle bar, also have shifting chute, the push-and-pull ring is housed on the handle bar can move forward and backward along shifting chute, and drive clamp interlock pipe also moves forward and backward.

There is finger ring at handle bar rear portion at operating grip, and fixed muffle is equipped with in the front portion, and above-mentioned conduit inserts and is fixed in the fixed muffle, and above-mentioned switch and socket are contained on the fixed muffle, make things convenient for power line to pass the resin outer tube and are connected with switch with socket.Fix at peripheral reinforcing sleeve in addition of catheter tail and fixed muffle.

The aforesaid operations control device is a clamp control device, and it is made up of clamp interlock pipe, two interlock steel wires, the ring of living, fan sheet and push-and-pull rings.

Above-mentioned clamp lower end connects two fan sheets, fan sheet middle part porose with the clamp holder on axle cooperates, there is aperture fan sheet lower end, the interlock steel wire passes through this aperture and fans sheet and be connected; The ring of living is passed at two interlock steel wire middle parts, and the other end connects clamp interlock tube head, and clamp interlock pipe afterbody and push-and-pull ring are fixed.Above-mentioned push-and-pull ring is contained in the operating grip periphery; The push-and-pull ring drives clamp interlock pipe along moving forward and backward of shifting chute and also moves forward and backward; And then drive by fanning the mechanism that sheet, ring alive and interlock steel wire constitute; Make interlock steel wire two ends open or draw in, clamp just can be realized opening and closing movement like this, reaches the purpose of sampling.

Above-mentioned light source can be the LED lamp, and it is contained in the clamp holder, and light is penetrated from the clamp holder, illuminates focus, makes the doctor can clearly see focus, and it is accurate, errorless to guarantee to take a sample; Above-mentioned object lens with image focusing in the digestive tract to fibre-optic end face; Through fibre-optic conduction; Can direct observation through eyepiece, the present invention outputs to display device such as computer through the CCD optical interface that is contained in behind the eyepiece with image, realizes screen display; And in computer the trend through mathematical model comparison software prevision Abnormal Development, and set up trend intelligent analysis system, set up the data base.

Above-mentioned resin outer tube is spiraled by two pitch tubes and forms; Pass through the positive and negative electrode power line in it respectively; Positive and negative electrode power line one end is connected with the positive and negative electrode of light source respectively, and the negative power supply jack is connected on the other end of anode power cord and the socket, and the cathode power supply jack of socket is connected through lead with a contact of switch; The other end of cathode power supply line is connected with another contact of switch, so just forms the loop to realize the power supply control to light source.

The present invention adopts the beneficial effect of such scheme to be: when 1) using this multi-functional biopsy to clamp; When it gets into digestive tract inside; Can clearly see focus through illuminator and supervising device, it is accurate, errorless to guarantee to take a sample, and is difficult for hurting other organs; Alleviate patient's misery, reached the effect of operation well; 2) illumination is stable, and acomia thermal phenomenon can accurately be judged, and is safe and reliable, improves the accuracy rate and the convenience of biopsy forceps greatly, and reliability is high, long service life; 3) set up mathematical model through the shooting analysis; The mathematical model of being gathered can note abnormalities through the front and back comparison software automatically; And when noting abnormalities, report to the police, can draw a pathological changes trend development direction simultaneously, so just can prevent, in time take in case of necessity the treatment measure in advance.Trend through mathematical model comparison software prevision Abnormal Development simultaneously, and set up trend intelligent analysis system, set up the data base, abundant clinical database can draw a lot of useful unusual experiences, and our doctor's medical skill level is improved constantly.
