Description
Technical field
This utility model relates to medical instruments field, particularly relates to a kind of pinpoint endoscope-use biopsy forceps.
Background technology
In clinical medicine checks, splanchnoscopy is widely used as a kind of method of auxiliary diagnosis.Biopsy forceps can enter in patient body by endoscope, checks disease in body, gripping pathological tissues, for diagnosis provides pathology foundation.
Because the flexibility ratio of the binding clip of existing biopsy forceps is limited, the problem can not accurately located when there is biopsy.Early stage at pathological tissues, because target is little, and may also have edema around pathological tissues, uses biopsy forceps gripping pathological tissues to have certain blindness, can not obtain result accurately.In addition, when the angle of biopsy forceps and pathological tissues is improper, can not accurate gripping pathological tissues.
Therefore, needing to develop one can pinpoint scope biopsy forceps.
Utility model content
In order to solve the problem, the purpose of this utility model is to provide a kind of endoscope-use biopsy forceps, and the binding clip of described biopsy forceps can rotate, and can adjust the flexibility of biopsy forceps far-end, thus realizes accurately sampling.
Biopsy forceps of the present utility model comprises the handle, fixed cover, conduit and the binding clip that connect successively, wherein, cavity is provided with in the middle part of fixed cover, outside fixed cover, cover has control loop, control loop is connected with binding clip with the steel wire in conduit by fixed cover, it is characterized in that, described control loop is rotatable, binding clip can be made to rotate by Spin Control ring.
By rotating control loop, binding clip 360 degree rotation can be realized.
Further, described biopsy forceps comprises the control assembly be positioned on fixed cover further, and the far-end of conduit can be made to bend by mobile control unit, term " far-end " is the one end away from handle herein, namely near one end of binding clip.
Described control assembly can be control handle, slide block or draw ring etc.Control handle, slide block or draw ring are connected with binding clip by control line, and wherein, control line passes from the cavity of fixed cover and the inside of conduit successively.
Conduit can be made to bend to specific direction at the far-end near binding clip by control handle and control line, and the flexibility of far-end can also be controlled by control line.By controlling the hardness of conduit at the material of the far-end near binding clip, conduit bending at the far-end near binding clip just can be realized.
Can be one or more according to control line of the present utility model, by arranging many control lines, conduit can be controlled bending to different directions at the far-end near binding clip.
Described binding clip is two, and the jaw of binding clip can be crocodile profile of tooth, but also can be other any suitable shapes.
Described biopsy forceps comprises the locking pin be located between two binding clips further.
Be rotatable according to the control loop of biopsy forceps of the present utility model, binding clip 360 degree rotation can be realized by Spin Control ring; And by control handle and control line, biopsy forceps is bent at the far-end near binding clip, obtains the tissue samples that existing biopsy forceps usually can not arrive or not easily arrive region.Therefore, use biopsy forceps of the present utility model both can accurately sample, can sample time be shortened again.

Fig. 1 is the structural representation according to biopsy forceps of the present utility model;
Wherein, 1, hands handle; 2, fixed cover; 3, conduit; 4, binding clip; 5, cavity; 6, control loop; 7, steel wire; 8, control handle; 9, control line; 10, locking pin.
Detailed description of the invention
Below in conjunction with accompanying drawing, biopsy forceps of the present utility model is described in detail.
Fig. 1 is the structural representation according to biopsy forceps of the present utility model.
With reference to Fig. 1, handle 1, fixed cover 2, conduit 3 and binding clip 4 is comprised according to biopsy forceps of the present utility model, wherein, handle 1 is connected with fixed cover 2, the middle part of fixed cover 2 is provided with cavity 5, the outside cover of fixed cover 2 has control loop 6, and fixed cover 2 is connected with conduit 3 away from one end of handle 1, and the outer end of conduit 3 is connected with binding clip 4; Control loop 6 is connected with binding clip 4 by the steel wire 7 in conduit 3.
Control loop 6 is the movable opening and closing that can control binding clip 4 on fixed cover 5.
Control loop 6 is rotatable, by rotating control loop 6, conduit 3 can be driven to rotate together with binding clip 4, realize 360 degree of rotations of binding clip, thus can accurately sample.
As the selectable mode of one, conduit 3 can also be driven to rotate together with binding clip 4 by turning handle 1, thus realize the rotation of binding clip 4.
In addition, biopsy forceps of the present utility model also comprises control assembly, and in an embodiment, control assembly is control handle 8.Control handle 8 is connected with binding clip 4 by control line 9, and wherein, control handle 8 is positioned on fixed cover 2, and control line 9 passes from the inner chamber of the cavity of fixed cover 2 and conduit 3 successively.
Except control handle, also can adopt other control assembly, such as, slide block, draw ring etc., can realize object of the present invention equally.
Different cavitys can be set in conduit 3, make steel wire 7 and control line 9 pass conduit 3 respectively by different cavitys, be then connected with binding clip 4.
Pull control line 9 by turn control handle 8, thus make conduit bending to a direction at the far-end near binding clip 4, such as, by making conduit 3 more pliable and tougher at the material of the far-end near binding clip, just can realize far-end by pulling control line 9 and bend; And the flexibility of far-end can also be controlled by control 9 line, such as, make front end upwarp the angle of 0-30 degree, according to actual needs, suitable flexibility can be selected, reach desirable sample position.
Can be one or more according to control line of the present utility model, by arranging many control lines, biopsy forceps can be controlled bending to different directions at the far-end near binding clip.
Described binding clip 4 is two, and the jaw of binding clip 4 is crocodile profile of tooth, but also can be other shapes.Two binding clips form the cavity holding sample, also comprise the locking pin 10 between two binding clips in cavity.
Below in an illustrative manner biopsy forceps of the present utility model is described, those skilled in the art is to be understood that, the disclosure is not limited to embodiment described above, when not departing from scope of the present utility model, can make a variety of changes, changes and replace.
