Embodiment Construction
[0018] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings, and the described embodiments are part of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by other researchers in the field without making creative designs fall within the protection scope of the present invention.
[0019] The coring sample enters from the fiberoptic bronchoscope, and a rotational torque is applied to the screw feeding operation end, so that the coring and sampling puncture needle enters the pathological tissue for sampling.
[0020] After the collection of pathological tissue is completed, all the coring samplers are withdrawn from the bronchoscope to complete the sampling. In this way, the collected volume is sufficient and the collected tissue volume presents a complete bar-shaped column.
[0021] In order to connect firmly and relia...

The invention discloses a sampling puncture needle comprising a coring sampling needle head and a steel wire flexible shaft, and relates to the technical field of medical instruments. The sampling puncture needle comprises the coring sampling needle head part for obtaining complete tissues, and the steel wire flexible shaft part for being connected with the coring sampling needle head. The coringsampling needle head firstly rotates to enter lesion tissues, and the obtained tissue is stored in the coring sampling needle head. The steel wire flexible shaft is connected with the coring samplingneedle head through trapezoidal threads and used for connecting two shafts which are not located on the same axis so as to transmit rotary motion and torque, and the rotary motion and the torque can be flexibly transmitted to any position. The coring sampling needle head part is rotated into the tissue, the obtained tissue is stored in the coring sampling needle head, and the coring sampling needle head has the characteristics of complete tissue acquisition and high practicability.
Description
technical field [0001] The invention relates to the field of medical equipment technology and precision parts manufacturing technology, in particular to a coring and sampling needle structure. Background technique [0002] When sampling with a puncture needle, the main problem in clinical practice is that the probability of the sample tissue being strip-shaped is not high, and some of it is a fragment-like tissue block. When the shape of the specimen is fragment-like tissue, it cannot be directly sent for pathological examination. Some methods are used to make the fragments agglomerate, which wastes a certain cost. If the fragments cannot be agglomerated, the sampling operation needs to be performed again, which increases unnecessary troubles and makes it inconvenient for medical staff to use the puncture guide needle. Therefore, designing new biopsy needles has become an important task for those skilled in the art in order to obtain more complete and usable tissues. [000...
