The working principle of the embodiment of the invention is as follows:
as shown in fig. 1-7, specifically, the sampling tube 5 is installed in the outer needle tube 1 in a matching way, under the drive of the sampling motor 4, when the outer needle tube 1 is penetrated into a body, the sampling tube 5 is pushed out from the outer needle tube 1, the sampling groove 50 at the end part of the sampling tube 5 extends out of the needle 11 part, pathological tissues of the sampling part fall into the sampling groove 50, and when the sampling tube 5 returns to the inside of the outer needle tube 1, the pathological tissues are left in the sampling groove 50. In order to ensure that the sampling tube 5 reliably retracts into the outer needle tube 1 after sampling, the stepped shaft 52, the contraction section 12 and the return spring 54 are arranged, and when the sampling motor drives the sampling tube 5 to retract after sampling is finished, the compressed return spring 54 returns to the original state, so that the sampling tube 5 is ensured to return into the outer needle tube 1, and pathological tissues can be obtained by pulling out the outer needle tube 1. In order to improve the sampling accuracy of pathological parts, the memory metal sleeve 13 is arranged on the contraction section 12 of the outer needle tube 1, the memory metal sleeve 13 is outwards opened, the pathological tissue is more dense than the normal organism tissue, when the memory metal sleeve 13 on the outer needle tube 1 passes through the pathological tissue, the memory metal sleeve 13 is extruded with larger force, so that the airtight space between the contraction section 12 and the memory metal sleeve 13 is reduced, at the moment, air between the contraction section 12 and the memory metal sleeve 13 is sent into the resistance amplifying mechanism 3 by the air duct 14 for amplifying and displaying, and therefore the needle 11 part of a sampling personnel is prompted to be positioned at the pathological tissue part, and at the moment, the sampling tube 5 is pushed out for sampling by the cooperation of the sampling motor 4. Since the air duct 14 passes through the inside of the air duct 14, in order to avoid interference caused by the extension sampling of the sampling tube 5, the first return groove 53 and the second return groove 57 are respectively arranged on the sampling tube 5, and when the sampling tube 5 extends, the air duct 14 is positioned in the sections of the first return groove 53 and the second return groove 57. Air between the contraction section 12 and the memory metal sleeve 13 is sent into the position of the matching hole 33 through the air duct 14 under the extrusion of pathological tissues, the piston 34 is pushed to move upwards, the lifting rod 36 is driven to move upwards, the swinging frame 38 is controlled to swing in a linkage mode, the inserting rod 311 is controlled to move upwards at the moment, the conductive spring plate 315 is enabled to be connected with a conductive loop connected with the display lamp 31, the conductive loop is enabled to be lightened, the needle 11 of a sampling person is prompted to be located in the pathological tissue region, and sampling operation can be carried out. When the outer needle tube 1 is withdrawn from the pathological tissue part after the sampling is completed, the extrusion force to the memory metal sleeve 13 part is reduced, the memory metal sleeve 13 is re-opened at this time, the piston 34 is re-positioned under the drive of the supporting spring 313, and the conductive spring plate 315 breaks the conductive loop at this time. In order to ensure that the sampling groove 50 of the sampling tube 5 samples pathological tissues after being pushed out, the sampling groove 50 is connected with a suction assembly, when the sampling tube 5 is pushed out, a negative pressure tube 56 connected with the sampling groove 50 drives a rubber plug 61 in an air suction box 60 to move, air at the sampling groove 50 is fed into an area between the rubber plug 61 and the air suction box 60, at the moment, the sampling groove 50 adsorbs the pathological tissues, so that the pathological tissues fall into the sampling groove 50, and the pathological tissues are cut off and left in the sampling groove 50 in the process of backing the sampling tube 5, thereby completing the sampling of the pathological tissues. When the width range of some pathological tissues is smaller than the length between the needle 11 and the memory metal sleeve 13, the condition that the sampling tube 5 passes through the pathological tissues when pushing out the needle 11 for sampling can occur when the scale mark 100 is arranged for sampling the smaller part of some pathological tissue areas, at this time, according to the scale mark 100 on the outer needle tube 1, after the display lamp 31 is lightened, the distance between the needle 11 and the contraction section 12 is integrally pulled out of the outer needle tube 1 (the distance is a determined value and can be measured by the scale before sampling), so that the needle 11 is retracted to the pathological tissue part, and the pathological tissues are obtained after sampling. Through the mutual cooperation of the first incision 110 and the second incision 500, when the pathological tissue falls into the sampling groove 50, the retracted sampling groove 50 cuts off the pathological tissue and remains in the sampling groove 50, so that reliable sampling is further ensured.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention. Any reference sign in a claim should not be construed as limiting the claim concerned.
Furthermore, it should be understood that although the present disclosure describes embodiments, not every embodiment is provided with a separate embodiment, and that this description is provided for clarity only, and that the disclosure is not limited to the embodiments described in detail below, and that the embodiments described in the examples may be combined as appropriate to form other embodiments that will be apparent to those skilled in the art.
