Abstract
The utility model discloses a pair of wide-angle biopsy forceps for gastroscope, which comprises a biopsy forcep body, a twine hook push-pull rod, an inhaul cable, a flexible guide tube, a manipulated elbow and a twine hook, and further comprises a tong head bending and rotating operation wheel, a control rope and a 180-degree rotary disc, wherein the twine hook push-pull rod is connected with the left side of the biopsy forcep body in a sleeving manner, and connected with the twine hook through the inhaul cable; the tong head bending and rotating operation wheel is arranged in the middle of the biopsy forcep body; the right side of the biopsy forcep body is connected with the 180-degree rotary disc through the flexible guide tube; the right side of the 180-degree rotary disc is connected with the manipulated elbow; the twine hook is formed in the manipulated elbow; the control rope penetrates through the flexible guide tube and is connected with the tong head bending and rotating operation wheel and the 180-degree rotary disc. The pair of wide-angle biopsy forceps for the gastroscope is simple in structure, can manipulate the twine hook to bend through the tong head bending and rotating operation wheel, performs sampling on the stomach wall or bending part of the esophagus, and is simple for operation, convenient and practical.
Description
Technical field
This utility model relates to technical field of medical instruments, is specifically related to a kind of gastroscope Wide-angle biopsy forceps.
Background technology
The patients' such as gastropathy diagnosis, usually use biopsy forceps to be taken a sample to check, to determine pathologic feature, existing biopsy forceps, the direction of binding clip bending and angle are difficult to control, and vice body and pathological tissues are parastate more, when esophagus or the little crooked position of body of stomach are sampled, traditional biopsy forceps does not bend sampling by rotating self, impact diagnosis, inconvenient operation.
The utility model content
The purpose of this utility model is to overcome the shortcoming and defect of prior art, and a kind of gastroscope Wide-angle biopsy forceps is provided, and it is simple in structure, can handle the jaw bending by binding clip Bending Rotation hand wheel, coat of the stomach or esophagus bending place are sampled, simple to operate, convenient and practical.
In order to solve the existing problem of background technology, this utility model is by the following technical solutions:
A kind of gastroscope Wide-angle biopsy forceps, it comprises the biopsy forceps body, the jaw push-pull bar, drag-line, soft conduit, handled crooked head and jaw, the left side of described biopsy forceps body is socketed with the jaw push-pull bar, the jaw push-pull bar is connected with jaw by drag-line, it also comprises binding clip Bending Rotation hand wheel, control wire and 180 degree rotation discs, the centre of biopsy forceps body is provided with binding clip Bending Rotation hand wheel, the right side of biopsy forceps body connects 180 degree rotation discs by soft conduit, the right side of 180 degree rotation discs connects is handled crooked head, handled on crooked head and be provided with jaw, control wire runs through soft conduit and connects binding clip Bending Rotation hand wheel and 180 degree rotation discs.Manual rotation binding clip Bending Rotation hand wheel drives the control wire motion, and rotation disc is slow circumvolve under the drive of control wire, makes jaw bend, and internally the coat of the stomach pathological tissues is sheared.
As preferably, described jaw and to be handled crooked head be movable connection.
As preferably, described binding clip Bending Rotation hand wheel can 360 degree rotations.
As preferably, the internal diameter of described binding clip Bending Rotation hand wheel is greater than the internal diameter of 180 degree rotation discs, and bull wheel drives steamboat by control wire, simple to operate, convenient and practical.
This utility model operation principle: when coat of the stomach is sampled, at first biopsy jaw and soft conduit are reached to gastric from esophagus, then find pathological tissues by endoscope, then manual rotation binding clip Bending Rotation hand wheel drives the control wire motion, rotation disc is slow circumvolve under the drive of control wire, make jaw bend, internally the coat of the stomach pathological tissues is sheared.
Compared with prior art, the beneficial effects of the utility model are: it is simple in structure, can handle the jaw bending by binding clip Bending Rotation hand wheel, and coat of the stomach or esophagus bending place are sampled, simple to operate, convenient and practical.
The accompanying drawing explanation
Below by embodiment, by reference to the accompanying drawings this utility model is further described.
Fig. 1 is structural representation of the present utility model;
1 is the biopsy forceps body, and 2 is the jaw push-pull bar, and 3 is drag-line, and 4 is soft conduit, and 5 are handled crooked head, and 6 is jaw, and 7 is binding clip Bending Rotation hand wheel, and 8 is control wire, and 9 is 180 degree rotation discs.
The specific embodiment
As shown in Figure 1, a kind of gastroscope Wide-angle biopsy forceps, it comprises biopsy forceps body 1, jaw push-pull bar 2, drag-line 3, soft conduit 4, handled crooked 5 and jaw 6, the left side of described biopsy forceps body 1 is socketed with jaw push-pull bar 2, jaw push-pull bar 2 is connected with jaw 6 by drag-line 3, it also comprises binding clip Bending Rotation hand wheel 7, control wire 8 and 180 degree rotation discs 9, the centre of biopsy forceps body 1 is provided with binding clip Bending Rotation hand wheel 7, the right side of biopsy forceps body 1 connects 180 degree rotation discs 9 by soft conduit 4, the right side of 180 degree rotation discs 9 is connected with is handled crooked 5, handled on crooked 5 and be provided with jaw 6, control wire 8 runs through soft conduit 4 and connects binding clip Bending Rotation hand wheel 7 and 180 degree rotation discs 9.It is movable connection that described jaw 6 and quilt are handled crooked 5.Described binding clip Bending Rotation hand wheel 7 can rotate by 360 degree; The internal diameter of binding clip Bending Rotation hand wheel 7 is greater than the internal diameter of 180 degree rotation discs 9, and bull wheel drives steamboat by control wire, simple to operate, convenient and practical.
When coat of the stomach is sampled, at first jaw 6 and soft conduit 4 are reached to gastric from esophagus, then find pathological tissues by endoscope, then manual rotation binding clip Bending Rotation hand wheel 7 drives control wire 8 motions, 180 degree rotation discs 9 slow circumvolve under the drive of control wire 8, make jaw 6 bend, internally the coat of the stomach pathological tissues is sheared.
Above-described embodiment; it is an example of the present utility model; be not for limiting enforcement of the present utility model and interest field, all or technical schemes of being equal to identical with the described content of this utility model claim, all should be included in this utility model protection domain.
