Description

The biopsy forceps that utilizes optical fibers to focus on

One, technical field

The present invention relates to a kind of biopsy forceps, especially a kind of biopsy forceps that utilizes optical fibers to focus on.

Two, background technology

Endoscope is mainly as the intravital indirect observation inspection of patient, takes off a spot of biological tissue in this position in patient's cavity and does the pathology cut sections for microscopic examination when needing for suspicious part further to check often to need when confirming to enter from endoscope channel with biopsy forceps.

In the prior art, when medical steel biopsy forceps is got pincers alive in inspection,, can't know the definite position of focus, cause the error of taking a sample easily, and then cause doctor's mistaken diagnosis owing to be outside 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 biopsy forceps that utilizes optical fibers to focus on is 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 biopsy forceps that utilizes optical fibers to focus on, it comprises clamp, clamp holder, spring outer tube, resin duct, operating grip and operating control device, is characterized in: it also comprises the illuminator of being made up of optical fibers, condenser lens, light source, battery and switch; But described clamp is made of the hollow structure binding clip of the bullet-shaped of two correspondence foldings, and moves forward and backward the realization folding by a clamp interlock pipe in the resin duct; The handle bar of described operating grip is end sealing, the hollow structure that one end is got through, intracavity has fixing fibre-optic center that the fixed leg of through hole is arranged in it, and described optical fibers one end is positioned at the focus point of condenser lens, and the other end enters in the binding clip after passing clamp interlock pipe; Also have shifting chute on the handle bar, mobile control loop is housed on the handle bar can move forward and backward along shifting chute, and drive clamp interlock pipe also moves forward and backward; Described operating 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 mobile control loops.

Above-mentioned clamp lower end connects two fan sheets, and fan sheet middle part axle porose and on the clamp holder cooperates, and there is aperture fan sheet lower end, and the interlock steel wire is connected with the fan sheet by this aperture; 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 mobile control loop leading flank are fixed, and makes mobile control loop can drive clamp interlock pipe when front and back are mobile on operating grip and also moves forward and backward.

Above-mentioned mobile control loop is contained in the operating grip periphery, and move forward and backward by shifting chute, the drive clamp interlock pipe that moves forward and backward of mobile control loop 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 switch is finger ring the place ahead on operating grip, and itself and battery electrically connect, and control battery operated; Battery is contained in the handle bar afterbody of operating grip, battery makes light source luminescent for the light source that is contained in its place ahead provides power supply, and focus on the optical fibers by the condenser lens that is contained in light source the place ahead, transport light on the clamp by optical fibers, illuminate focus, make the doctor can clearly see focus, it is accurate, errorless to guarantee to take a sample.

Above-mentioned resin duct afterbody is with reinforcing sleeve outward, and reinforcing sleeve also has fixed muffle to be connected with operating grip outward.

The present invention adopts the beneficial effect of such scheme to be: when 1) using this biopsy forceps that utilizes optical fibers focusing, when it enters intestinal inside, can clearly see focus by illuminator, it is accurate, errorless to guarantee to take a sample, and be difficult for hurting other organs, alleviate patient's misery, reached the effect of operation well; 2) utilize condenser lens and optical fibers to focus on reliability height, long service life; 3) 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.
