Abstract

The utility model provides a technical project of an internal living tissue sampler. The utility model primarily comprises a looking glass with an object looking head of a looking glass, a looking glass light guide fiber and a looking glass visual head. The utility model is characterized in that an inner jacket tube is fixed outside the object looking head of a looking glass and part of the looking glass light guide fiber, and an outer jacket tube used for stopper control trace movement is arranged on the external side of the inner jacket tube; the front end of the outer jacket tube is provided with a movable sampling knife clack of which both side edges are provided with cutting edges, and the sampling knife clack and the outer jacket tube are hinged through a hinge; the sampling knife clack and the inner jacket tube are movably connected through a fulcrum. With the structure, the movable sampling knife clack can open or close according to the relative movement of the inner and the outer jacket tubes. When the movable sampling knife clack is closed, the movable sampling knife clack forms a tapered shape, and the utility model is in favor of being inserted in a body. The utility model can opened in the living tissue, and can be used for observing and exactly choosing a sampling point; the movable sampling knife clack is closed to cut living tissues; the living tissues sampled are packed in the movable sampling knife clack, and then living tissues sampling is finished. The utility model is used for sampling the living tissues has the advantages of time saving, labour saving and little pain on a patient.

Description

Living tissue sampler in a kind of body

Affiliated technical field:

The utility model relates to and be used for bioptic sampler on a kind of medical diagnosis, living tissue sampler in especially a kind of body.

Background technology:

Some disease often needs the living tissue of affected area is carried out the sample examination inspection, in the prior art when diagnosis, known method is the sampling of surgical incision lesion tissue, sampling in this way, not only time-consuming, effort, and also the misery that causes to patient is also big.

Summary of the invention:

This utility model is at the existing in prior technology deficiency, and living tissue sampler technical scheme in a kind of body is provided.

This programme is realized by following technical measures: mainly comprise having the sight glass that sight glass is looked the visual head of thing head, sight glass optical fibers and sight glass, the characteristics of this programme are to look the thing head and the fibre-optic fixed outside of part sight glass has inner sleeve at described sight glass, having in the outside of inner sleeve can be along axis relative to the micro-trocar sheath that moves of inner sleeve, telescopic outside front end has three to the pintongs active samlping knife clack, there is hinge to be connected between this active samlping knife clack and the trocar sheath, has fulcrum to flexibly connect between the end of active samlping knife clack and the inner sleeve.The concrete characteristics of this programme also have, and at the dual-side of described each active samlping knife clack cutting edge are arranged.Between described inner sleeve and trocar sheath, stop is arranged.

The beneficial effect of this programme can be learnt according to the narration to such scheme, because in this scheme, look the thing head and the fibre-optic fixed outside of part sight glass has inner sleeve at the sight glass of sight glass, there is trocar sheath outside at inner sleeve, and by the stop between two sleeve pipes control between the inside and outside sleeve pipe relative to the trace moving, telescopic outside front end has three the active samlping knife clack of cutting edge to be arranged to the pintongs dual-side, there is hinge to be connected between this active samlping knife clack and the trocar sheath, and has fulcrum to flexibly connect between the inner sleeve.This structure, active samlping knife clack can open under inside and outside telescopic relatively moving or be closed, when active samlping knife clack is closed, active samlping knife clack is taper, help inserting in the body, after in active samlping knife clack is inserted into body, open active samlping knife clack at affected area, just can be observed the position that needs sampling with sight glass, make an accurate selection of sample point, closed active samlping knife clack excision living tissue wraps in the living tissue that is sampled in the active samlping knife clack, extract sampler, need just can obtain the living tissue of sampling.The living tissue sampling of carrying out with the method can save time, laborsaving, and the misery that patient is caused is also little.This shows that this utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.

Description of drawings:

Fig. 1 is the part sectional structure sketch map of this utility model specific embodiment.

1 is active samlping knife clack among the figure, and 2 look the thing head for sight glass, and 3 is inner sleeve, and 4 is trocar sheath, and 5 is the visual head of sight glass, and 6 is the sight glass optical fibers, and 7 is stop.

The specific embodiment:

For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by a specific embodiment.

By accompanying drawing as can be seen, living tissue sampler in the body of this programme, comprise that mainly having sight glass looks thing head (2), the sight glass of the visual head of sight glass optical fibers (6) and sight glass (5), the characteristics of this programme are in the fixed outside that described sight glass is looked thing head (2) and part sight glass optical fibers (6) inner sleeve (3) to be arranged, having in the outside of inner sleeve (3) can be along axis relative to the micro-trocar sheath (4) that moves of inner sleeve (3), front end at trocar sheath (4) has three to pintongs active samlping knife clack (1), there is hinge to be connected between this active samlping knife clack (1) and the trocar sheath (4), has fulcrum to flexibly connect between the end of active samlping knife clack (1) and the inner sleeve (3).Dual-side at described each active samlping knife clack (1) has cutting edge.Trace between described inner sleeve (3) and trocar sheath (4) moves, and is to be restricted by the stop (7) between inner sleeve (3) and the trocar sheath (4).

Claims
