Technical field
This utility model relates to a kind of for the medical devices in biological living, is used in particular for the medical thing string bag of getting of under bronchoscope, specimen tissue being collected.
Background technology
Along with the development of medical science and technology, more and more general to the diagnosis of pulmonary disease and treatment under bronchoscope at present.
Under bronchoscope, obtain histological specimen and generally take biopsy forceps pincers to get, after collecting a sample at every turn, apparatus need to be taken out just and can obtain sample from scope, if need a plurality of samples, just need repeatedly repetitive operation, more consuming time.If can carry out in vivo a plurality of tissue collectings, will reduce operating time, alleviate patient's misery.
Under bronchoscope mirror, treatment as freezing freezing are got tumor tissues at present, because specimen is larger, cannot directly tissue be taken out in body, often need cryoprobe along with bronchoscope is released in patient airway together, repeated multiple times bronchoscope enters in patient's body, the misery that increases very much patient, wastes time and energy.
Therefore, along with the rising of lung cancer morbidity rate, in order to alleviate better patient's misery, design a kind of simple for structurely, simple to operate, do not affect patient's respiratory function, can the pincers of tissue get or the excision process of tumor in, the apparatus of directly tissue being collected is in vivo very important.
Utility model content
A kind of medical thing string bag of getting that utility model object: technical problem to be solved in the utility model is for the deficiencies in the prior art, provides and can coordinate biopsy forceps, the freezing product of Denging is collected tissue.
In order to solve the problems of the technologies described above, the utility model discloses a kind of medical thing string bag of getting, the front hand grip assembly and the back handle assembly that comprise mutual combination, described back handle assembly comprises back handle, drag-line and the string bag connecting successively, front hand grip assembly comprises front hand grip and outer tube, and described drag-line is through the inner chamber of front hand grip and outer tube; The described string bag is the string bag of metal wire knitted, and one end of the string bag has opening, and the string bag can shrink and enter in outer tube under the pulling force effect of drag-line.String bag integral body has contraction elasticity.Described drag-line is vertical with the plane that the opening of the string bag forms.
In this utility model, between the described string bag and drag-line, be provided with a spring.
In this utility model, on described back handle, be connected with the boost tube that is nested in drag-line outside.
In this utility model, described back handle end is provided with for locking the latch-up structure of boost tube, and described latch-up structure comprises contraction screw thread openings and the lock nut of back handle end.
In this utility model, described front hand grip end is provided with for locking the latch-up structure of outer tube, and described latch-up structure comprises contraction screw thread openings and the lock nut of front hand grip end.
In this utility model, the described string bag is the braiding of nickel-titanium metal silk.
Beneficial effect: this utility model is simple in structure, easy operating, can coordinate biopsy forceps, and ESD electric knife or freezing a plurality of organizing in vivo collected is saved operating time, alleviates patient's misery.And in this utility model, thereby the plane that the opening of described drag-line and the string bag forms vertical make string bag opening and sample pickup tongs sample presentation direction consistent, facilitate doctor, when operating, sample is directly sent into the string bag.Meanwhile, for fear of the string bag, run in vivo and block the situation be difficult to open, this utility model is fixed on spring one end on drag-line, and one end is fixed on the string bag, when such design can make the string bag release outer tube by the restoring force smooth opening to spring.
