Natural cavity diseases such as human digestion, urinary and respiratory diseases are high-incidence diseases, seriously endanger the physical health of people, and the morbidity and mortality of diseases such as esophagus cancer, stomach cancer, colorectal cancer, bladder cancer, lung cancer and the like are the most common malignant tumors in China. With the development of robotics, an Endoscopic Nurse/Technician Robot (endo-Nurse/technologian Robot) has been developed for performing interventional instrument operations with an endoscope, thereby improving the medical operation level and alleviating the problem of medical resource shortage.
Histopathology is a gold standard for diagnosis of many diseases, and is also a molecular basis for accurate treatment and prognosis, and diagnosis and treatment of tumors, inflammations and the like require cellular molecular information of histopathology. Biopsy tissue is the living tissue of a target organ acquired by a biopsy instrument in the processes of endoscope, operation and the like, so as to further perform pathological detection.

Detailed Description
The core of the invention is to provide a human body biopsy tissue extraction and collection mechanism so as to reduce labor cost, reduce cross infection risk and improve work specification and efficiency.
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
As shown in fig. 1, an embodiment of the present invention discloses a human body biopsy tissue extraction and collection mechanism comprising a frame 100, a three-way device 300, a way switching device 200, a container support device 600, and an oscillation device 400.
The rack 100 is a supporting component of the human body biopsy tissue extraction and collection mechanism, and is used for providing a mounting base for other devices, and the structure and the shape of the rack can be designed according to practical situations.
The three-way device 300 is provided on the housing 100 and includes an inlet channel 301 for passing through the biopsy instrument 10, a biopsy acquisition channel 302, and a biopsy extraction channel 303, the inlet channel 301, the biopsy acquisition channel 302, and the biopsy extraction channel 303 being in communication. Since biopsy instrument 10 has a certain stiffness, biopsy instrument 10 is easier to access into biopsy acquisition channel 302 when extended from inlet channel 301.
In this embodiment, as shown in fig. 2-4, the inlet channel 301 and the biopsy collecting channel 302 may be positioned on the same line, and the inlet channel 301 and the biopsy collecting channel 302 may be designed to be horizontal or nearly horizontal, so that the biopsy instrument 10 may more easily enter the biopsy collecting channel 302 when extending from the inlet channel 301.
The access switching device 200 is disposed on the rack 100, and is used for controlling the access device 300 to switch between a first state and a second state. With the three-way device 300 in the first state, the inlet channel 301 and the biopsy acquisition channel 302 form a biopsy acquisition pathway through which the biopsy instrument 10 may be passed, the biopsy instrument 10 being operable to acquire biopsy tissue.
With the three-way device 300 in the second state, the inlet channel 301 and the biopsy extraction channel 303 form a biopsy extraction passageway through which the biopsy instrument 10 passes, through which the biopsy instrument 10 may extract harvested biopsy tissue. The channel switching device 200 can control the state of the three-channel device 300 according to the requirement.
The container holding device 600 is used to hold the tissue collecting container 500 such that the tissue collecting container 500 is arranged corresponding to the biopsy extraction channel 303, and the biopsy instrument 10 holds the biopsy tissue to extend into the tissue collecting container 500 when extracting the biopsy tissue. I.e., the exit direction of biopsy extraction channel 303 is directed toward tissue collection container 500, so that biopsy instrument 10 may be successfully advanced into tissue collection container 500.
The oscillating device 400 is disposed on the frame 100, and is used for performing an oscillating operation on the biopsy instrument 10, so that the biopsy tissue clamped by the biopsy instrument 10 can be separated from the biopsy instrument 10 under the oscillating action and fall into the tissue collecting container 500.
When the human body biopsy tissue extraction and collection mechanism provided by the invention is used for tissue biopsy, the biopsy instrument 10 enters through the inlet channel 301, stretches out through the biopsy acquisition channel 302, acquires the biopsy tissue of a corresponding part, clamps the biopsy tissue to retreat after the acquisition is completed, and switches the three-way device 300 to the second state through the channel switching device 200 after the biopsy acquisition channel 302 is withdrawn, so that the inlet channel 301 and the biopsy extraction channel 303 form a biopsy extraction channel for the biopsy instrument 10 to pass through. Biopsy instrument 10 is then advanced such that biopsy instrument 10 enters biopsy extraction channel 303 and is transported along biopsy extraction channel 303 until it is delivered into tissue collection container 500. The oscillating device 400 performs an oscillating operation on the biopsy instrument 10 to cause biopsy tissue gripped by the biopsy instrument 10 to be oscillated off into the tissue collection container 500.
The human body biopsy tissue extraction and collection mechanism provided by the invention can timely extract and collect the biopsy tissue and store the biopsy tissue in the tissue collection container 500 after the biopsy tissue is collected, and a doctor does not need to transfer the biopsy tissue to a nurse, so that the risk that the biopsy tissue contacts other infection sources is reduced. In addition, the biopsy instrument 10 is oscillated by the oscillation device 400, so that manual oscillation of medical staff is not needed, and the labor intensity of the medical staff is reduced.
As shown in fig. 6, when biopsy instrument 10 passes through biopsy extraction channel 303, because of the rigidity of biopsy instrument 10, it will abut against the outer inner wall of biopsy extraction channel 303, and will tilt to the left at a large angle (view of fig. 6) after extending out of biopsy extraction channel 303. To overcome this problem, in this embodiment, the biopsy extraction channel 303 is an arc channel protruding toward the biopsy collection channel 302, and the outlet section of the biopsy extraction channel 303 is a deviation correction channel 304 guiding toward one side of the inlet channel 301, and the biopsy instrument 10 is guided to the right side (view angle of fig. 6) under the action of the deviation correction channel 304, so that after the biopsy instrument 10 protrudes from the biopsy extraction channel 303, it extends in a vertically downward direction to smoothly enter into the tissue collection container 500.
It should be noted that, in this embodiment, a length of flexible tube may be disposed below the deviation correcting channel 304 to isolate the biopsy instrument 10 from direct contact with the oscillation device 400.
As shown in fig. 6, in one embodiment of the present invention, the path switching device 200 includes a switching ramp 204 and a switching drive assembly.
Wherein the three-way access device 300 has a ramp plate mounting area for mounting the switching ramp plate 204, which may be located above the intersection of the inlet channel 301, the biopsy acquisition channel 302 and the biopsy extraction channel 303. The switching ramp 204 is disposed in the ramp installation area in a reversible manner, and the switching of the path is realized by the turning action of the switching ramp 204.
The switch driving assembly is disposed on the stand 100, and is used for driving the switch ramp 204 to turn over, so that when the switch ramp 204 is in the first position, the inlet channel 301 and the biopsy collecting channel 302 form a biopsy collecting channel for the biopsy device 10 to pass through, and after the biopsy device 10 enters from the inlet channel 301, the biopsy collecting channel 302 is easier to enter, that is, the biopsy collecting channel is easier to pass through, because the inlet channel 301 and the biopsy collecting channel 302 are located on the same straight line.
When the switch ramp 204 is in the second position, the switch ramp 204 blocks the communication of the inlet channel 301 and the biopsy acquisition channel 302, i.e. the biopsy acquisition path that is more easily penetrated by the biopsy instrument 10 is blocked by the switch ramp 204, such that the biopsy instrument 10 can only penetrate the biopsy extraction path formed by the inlet channel 301 and the biopsy extraction channel 303.
Further, one end of the switching ramp 204 is connected to the three-way device 300 through an elastic member, and specifically, an end of the switching ramp 204 may be provided with a mounting hole into which the elastic member is inserted. The other end of the switching ramp 204 is a flip end, and when the elastic member is in the reset state, the switching ramp 204 is located at the first position. The switch driving component can push down the turnover end of the switch slope plate 204 in a push-down mode, so that the switch slope plate 204 turns over to block the biopsy acquisition passage, and when the biopsy acquisition passage needs to be opened, the push-down action of the switch driving component is only required to be released, so that the switch slope plate 204 can be reset to the first position under the action of the elastic piece.
To facilitate passage of the biopsy instrument 10 through the biopsy extraction channel, in this embodiment, the side of the switch ramp plate 204 facing the biopsy extraction channel 303 has a guide slot that guides the biopsy instrument 10 to the biopsy extraction channel 303. Under the influence of the guide slot, it is easier to redirect the biopsy instrument 10 from the inlet channel 301 into the biopsy extraction channel 303.
Further, the switching drive assembly includes a switching drive 201 and a flip cam 203. The switching driving device 201 may be disposed on the rack 100 through the switching base 202, and the switching driving device 201 may be a driving motor. The turning cam 203 is disposed on the output shaft of the switching driving device 201 to drive the switching ramp plate 204 to turn to the second position. The switching driving device 201 drives the turning cam 203 to rotate, and the switching ramp plate 204 is pressed down by the turning cam 203, so that the switching ramp plate 204 is turned to the second position. After the biopsy instrument 10 passes through the biopsy extraction channel 303 smoothly, the switching driving device 201 drives the turning cam 203 to reset, and the switching slope plate 204 automatically returns to the first position by the elastic force of the elastic member.
As shown in FIG. 6, in one embodiment of the present invention, the holster 100 has a collection extension channel 101 in communication with a biopsy collection channel 302, and further has an inlet extension channel 102 in communication with an inlet channel 301, with a three-way device 300 disposed between the collection extension channel 101 and the inlet extension channel 102.
Disposed within the acquisition extension channel 101 is a position sensor 103 for detecting the position of the implement of the biopsy instrument 10. After the position sensor 103 detects the actuator of the biopsy instrument 10 and a preset time has elapsed, the switch drive assembly drives the switch ramp 204 to flip to the second position.
Since the position sensor 103 is arranged in the acquisition extension channel 101 at a distance from the biopsy extraction channel 303, after the biopsy tissue has been acquired, the biopsy instrument 10 is retracted to the position where the position sensor 103 detects the position of the actuating part of the biopsy instrument 10, and a distance is provided between the actuating part and the biopsy extraction channel 303. Therefore, the actuator is detected by the position sensor 103, and after a preset time, the switch driving assembly drives the switch ramp 204 to flip to the second position to close the biopsy acquisition path.
As shown in fig. 7 and 8, in an embodiment of the present invention, the oscillating device 400 may be provided only in one or in a plurality, and two are described below as an example. The two oscillation devices 400 are a first oscillation device 410 and a second oscillation device 420, respectively.
The first oscillating device 410 and the second oscillating device 420 are identical in structure, and can be oppositely arranged on two sides of the biopsy instrument 10 and staggered up and down. The specific structure of the oscillation device 400 will be described herein taking the first oscillation device 410 as an example.
The first oscillating device 410 includes a first oscillating drive 412, a first oscillating fork 413, and a first active link 415. The first oscillation driving device 412 is disposed on the frame 100 through the first oscillation mounting seat 411, and the first oscillation driving device 412 may be a driving motor.
The first oscillating fork 413 is hinged to the first oscillating mount 411 by a first oscillating shaft 416, the first oscillating fork 413 having a first fork opening 4133 through which the biopsy instrument 10 passes, and an inner wall of the first fork opening 4133 may be provided with wave-shaped teeth to increase a contact area with the biopsy instrument 10.
The first driving link 415 is connected to the output shaft of the first oscillating driving device 412, so that the first driving link 415 performs a circular motion around the output shaft of the first oscillating driving device 412, and a person skilled in the art can design a distance between the first driving link 415 and the output shaft of the first oscillating driving device 412, that is, a radius of rotation of the first driving link 415, and then design an oscillating angle of the first oscillating fork 413 according to needs.
The first oscillating fork 413 is provided with a first oscillating chute 4132 matched with the first driving connecting rod 415 so as to toggle the first oscillating fork 413 to oscillate reciprocally around the first oscillating shaft 416. During oscillation of the first oscillating fork 413, the first fork opening 4133 of the first oscillating fork 413 moves the biopsy instrument 10 to shake off the biopsy tissue.
Further, the first oscillating device 410 may further include a first driven link 414, where the first driven link 414 is disposed on the first oscillating mount 411 through a swing arm, so that the first driven link 414 may swing along with the swing arm. The first oscillating fork 413 is provided with a first auxiliary chute 4131 cooperating with the first driven link 414. When the first oscillating fork 413 oscillates, the oscillating process of the first oscillating fork 413 is more stable under the cooperation of the first driven connecting rod 414 and the first auxiliary chute 4131.
Note that, the connection relationship between each component of the second oscillating device 420 (the second oscillating mount 421, the second oscillating driving device 422, the second oscillating fork 423, the second driven link 424, the second driving link 425, the second oscillating shaft 426, the second auxiliary chute 4231, the second oscillating chute 4232, the second fork 4233) and the component is the same as that of the first oscillating device 410, and the description thereof is omitted herein.
It is often desirable to sample tissue at different locations at a time, and in order to be able to collect multiple biopsies, tissue collection container 500 may include a container holder 502 and multiple collection tubes 501 secured to container holder 502, with the biopsies being collected by collection tubes 501.
To ensure that the biopsy extraction channel 303 can correspond to each collection tube 501, the biopsy instrument 10 may extend into each collection tube 501 as desired. As shown in fig. 4 and 10, in one embodiment of the present invention, the container support device 600 includes a tissue container support base 605 and a displacement drive assembly. Wherein, tissue container support base 605 is slidably disposed on bottom plate 104 of frame 100, tissue container support base 605 is configured to carry tissue collection container 500.
The displacement drive assembly is used to drive the sliding movement of tissue container support base 605 to switch between different collection tubes 501 of tissue collection container 500 to correspond to biopsy instrument 10. For example, a first collection tube 501 of the tissue collection container 500 may be initially positioned opposite the biopsy extraction channel 303, and after the first collection tube 501 has extracted biopsy tissue, the tissue collection container support base 605 is moved a set distance (i.e., the distance between two adjacent collection tubes 501) by the displacement drive assembly such that a second collection tube 501 of the tissue collection container 500 is positioned opposite the biopsy extraction channel 303 to extract and collect the second biopsy tissue, and after all collection tubes 501 have been completed, the new tissue collection container 500 is replaced.
As shown in fig. 2 and 4, in the present embodiment, the displacement drive assembly may include a displacement drive 601 and a drive rack 604. The displacement driving device 601 is disposed on the frame 100 through a displacement mounting seat 602, the displacement driving device 601 may be a driving motor, and a driving gear 603 is disposed on an output shaft thereof. A drive rack 604 is provided on the tissue container support base 605 and is meshed with the drive gear 603. The displacement driving device 601 drives the driving gear 603 to rotate, so that the driving rack 604 drives the tissue container supporting base 605 to slide. The displacement driving assembly is not limited to realizing displacement driving through a gear-rack mechanism, and can also be a driving mode such as a screw mechanism, an air cylinder, a linear motor and the like.
