Natural orifice diseases such as human digestion, urinary tract and respiration are high-incidence diseases which seriously harm the health of people, and the morbidity and mortality of diseases such as esophageal cancer, gastric 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 (Endoscopic nuclear/technical Robot) has been developed for performing interventional instrument operation with an endoscope, thereby improving the level of medical operation and alleviating the problem of shortage of medical resources.
Histopathology is the gold standard for diagnosis of many diseases and is the molecular basis for precise therapy, prognosis, and diagnosis and treatment of, for example, tumors, inflammation, etc., all require cellular molecular information for histopathology. Biopsy tissue is the living tissue of a target organ collected by a biopsy instrument in the process of endoscopy, operation and the like, and then pathological detection is carried out. After the biopsy tissue has been collected by the physician using the biopsy instrument, the biopsy tissue is typically manually removed by a nurse, such as a nurse/assistant, and removed from the biopsy instrument and stored in a tissue collection container. Since the biopsy tissue is often clamped or stuck or adhered to the biopsy instrument, when the nurse or assistant takes the biopsy tissue into the tissue collection container, the nurse or assistant needs to manually and repeatedly oscillate or manually peel off the biopsy instrument to oscillate or peel the biopsy tissue from the biopsy instrument into the tissue collection container, and then manually adhere a label to the biopsy instrument, which affects the working efficiency, causes operation errors, wastes consumables, increases the risk of cross-infection, and the like.

Detailed Description
The core of the invention is to provide a human biopsy tissue extracting and collecting mechanism, which can reduce the labor cost, reduce the risk of cross infection and improve the working specification and efficiency.
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
As shown in FIG. 1, the embodiment of the present invention discloses a human biopsy tissue collecting mechanism, which comprises a frame 100, a three-way device 300, a way switching device 200, a container supporting device 600 and an oscillating device 400.
Wherein, the frame 100 is a supporting component of the biopsy tissue collecting mechanism for providing a mounting base for other devices, and the structure and shape thereof can be designed according to actual situations.
A three-way device 300 is provided on the frame 100 and comprises an inlet channel 301 for passing through the biopsy instrument 10, a biopsy collecting channel 302 and a biopsy extracting channel 303, the inlet channel 301, the biopsy collecting channel 302 and the biopsy extracting channel 303 being in communication. Because biopsy instrument 10 has some rigidity, biopsy instrument 10 is more easily advanced into biopsy collection channel 302 when inserted through access channel 301.
In this embodiment, as shown in fig. 2-4, the inlet channel 301 and the biopsy collecting channel 302 may be located on the same straight 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 can enter the biopsy collecting channel 302 more easily when extending from the inlet channel 301.
The path switching device 200 is disposed on the rack 100 and controls the path switching device 300 to switch between a first state and a second state. When the three-way device 300 is in the first state, the inlet channel 301 and the biopsy taking channel 302 form a biopsy taking passage through which the biopsy instrument 10 may pass, through which the biopsy instrument 10 may take a biopsy.
When the three-way passage arrangement 300 is in the second state, the inlet passage 301 and the biopsy extraction passage 303 form a biopsy extraction passage through which the biopsy instrument 10 can pass, through which the biopsy instrument 10 can extract the collected biopsy tissue. The path switching device 200 can control the state of the three-path device 300 according to the requirement.
The container support 600 is adapted to support the tissue collection container 500 such that the tissue collection container 500 is disposed in correspondence with the biopsy extraction channel 303, and the biopsy instrument 10 holds the biopsy tissue extending into the tissue collection container 500 during the extraction of the biopsy tissue. I.e. the outlet direction of the biopsy extraction channel 303 is directed towards the tissue collection container 500, such that the biopsy instrument 10 can be smoothly introduced into the tissue collection container 500.
The oscillating device 400 is disposed on the frame 100 and is used for oscillating the biopsy instrument 10, so that the biopsy tissue held by the biopsy instrument 10 can be separated from the biopsy instrument 10 and fall into the tissue collection container 500 under the action of the oscillation.
When the biopsy tissue extracting and collecting mechanism is used for tissue biopsy, a biopsy instrument 10 enters through an inlet channel 301, extends out through a biopsy collecting channel 302 and collects biopsy tissues of corresponding parts, after the collection is completed, the biopsy instrument 10 clamps the biopsy tissues and retreats, and after the biopsy instrument 10 exits from the biopsy collecting channel 302, a three-way device 300 is switched to a second state through a way switching device 200, so that the inlet channel 301 and the biopsy extracting channel 303 form a biopsy extracting way for the biopsy instrument 10 to pass through. Biopsy instrument 10 is then pushed forward 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 oscillates the biopsy instrument 10 to shake off the biopsy tissue grasped by the biopsy instrument 10 into the tissue collection container 500.
The human biopsy tissue extracting and collecting mechanism provided by the invention can extract and collect the biopsy tissue in time and store the biopsy tissue in the tissue collecting container 500 after the biopsy tissue is collected, and does not need to be transferred to nurses by doctors, thereby reducing the risk that the biopsy tissue contacts other infection sources. In addition, the biopsy instrument 10 is oscillated by the oscillating device 400, so that manual oscillation of medical personnel is not needed, and the labor intensity of the medical personnel is reduced.
As shown in fig. 6, when the biopsy instrument 10 passes through the biopsy extraction channel 303, the biopsy instrument 10 is rigid and clings to the outer inner wall of the biopsy extraction channel 303, and is inclined to the left (viewing angle in fig. 6) after extending out of the biopsy extraction channel 303. To overcome this problem, in the present embodiment, the biopsy extraction channel 303 is an arc-shaped channel protruding toward the biopsy collection channel 302, and the outlet section of the biopsy extraction channel 303 is a deviation-correcting channel 304 guiding toward one side of the inlet channel 301, so that the biopsy instrument 10 is guided toward the right side (as viewed in fig. 6) by the deviation-correcting channel 304, so that the biopsy instrument 10 extends in a vertically downward direction after extending out of the biopsy extraction channel 303, and then smoothly enters the tissue collection container 500.
It should be noted that in this embodiment, a section of flexible tube may be further disposed below the deviation rectifying channel 304 for isolating the direct contact between the biopsy instrument 10 and the oscillating device 400.
In one embodiment of the invention, as shown in FIG. 6, the pathway switching device 200 includes a switching ramp 204 and a switching drive assembly.
Wherein the three-way device 300 has a ramp mounting area for mounting the switching ramp 204, which may be located above the intersection of the inlet channel 301, the biopsy taking channel 302 and the biopsy extraction channel 303. The switching slope plate 204 is arranged in the slope plate installation area in a turnover mode, and the switching of the path is achieved through the turnover action of the switching slope plate 204.
The switching driving assembly is arranged on the rack 100 and used for driving the switching slope plate 204 to turn over so as to switch the switching slope plate 204 between the first position and the second position, when the switching slope plate 204 is located at the first position, the inlet channel 301 and the biopsy collecting channel 302 form a biopsy collecting passage for the biopsy instrument 10 to pass through, and since the inlet channel 301 and the biopsy collecting channel 302 are located on the same straight line, the biopsy instrument 10 can more easily enter the biopsy collecting channel 302 after entering from the inlet channel 301, namely can more easily pass through the biopsy collecting passage.
When the switching ramp 204 is in the second position, the switching ramp 204 blocks the communication state of the inlet channel 301 and the biopsy collecting channel 302, i.e. the biopsy collecting passage which is more easily penetrated by the biopsy instrument 10 is blocked by the switching ramp 204, so that the biopsy instrument 10 can only penetrate the biopsy extracting passage formed by the inlet channel 301 and the biopsy extracting 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 a reset state, the switching ramp 204 is located at the first position. The switching driving assembly can be pressed downwards to switch the overturning end of the slope plate 204 in a pressing mode, so that the switching slope plate 204 is overturned to block a biopsy collecting passage, when the biopsy collecting passage needs to be opened, the switching driving assembly only needs to be released from pressing, and the switching slope plate 204 can be reset to the first position under the action of the elastic piece.
In order to facilitate the passage of the biopsy instrument 10 through the biopsy extraction passage, in this embodiment, the side of the switching ramp 204 facing the biopsy extraction channel 303 has a guide groove for guiding the biopsy instrument 10 to the biopsy extraction channel 303. Under the action 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 device 201 and a tumble 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 turnover cam 203 is disposed on an output shaft of the switching driving device 201 to drive the switching ramp 204 to turn over to the second position. The switching driving device 201 drives the turnover cam 203 to rotate, and the switching slope plate 204 is pressed downwards by the turnover cam 203, so that the switching slope plate 204 is turned to the second position. After the biopsy instrument 10 passes through the biopsy extraction channel 303, the switching driving device 201 drives the reverse cam 203 to reset, and the switching slope plate 204 is automatically restored to the first position by the elastic force of the elastic member.
As shown in FIG. 6, in one embodiment of the invention, the holster 100 has a collection extension channel 101 in communication with a biopsy collection channel 302 and 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.
A position sensor 103 for detecting the position of the implement of the biopsy instrument 10 is provided within the collecting extension channel 101. After the position sensor 103 detects the implement of the biopsy instrument 10 and a preset time has elapsed, the toggle drive assembly drives the toggle ramp 204 to flip to the second position.
Since the position sensor 103 is disposed within the collecting extension channel 101 at a distance from the biopsy extraction channel 303, after the biopsy tissue has been collected, the biopsy instrument 10 is retracted to a position where the actuator portion of the biopsy instrument 10 is detected by the position sensor 103, and then the actuator portion of the biopsy instrument 10 is at a distance from the position of the biopsy extraction channel 303. Therefore, the actuating portion is detected by the position sensor 103, and after a preset time, the switching driving assembly drives the switching ramp 204 to turn over to the second position, so as to close the biopsy collection path.
As shown in fig. 7 and 8, in an embodiment of the present invention, only one oscillating device 400 may be provided, or a plurality of oscillating devices may be provided, and two oscillating devices are provided 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 have the same structure, and can be oppositely arranged on two sides of the biopsy instrument 10 and staggered up and down. The first oscillating device 410 is taken as an example, and a specific structure of the oscillating device 400 is described.
The first oscillation device 410 includes a first oscillation drive 412, a first oscillation 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 has a first fork opening 4133 for the biopsy instrument 10 to pass through, and the inner wall of the first fork opening 4133 may be provided with wave-shaped teeth to increase the contact area with the biopsy instrument 10.
The first driving link 415 is connected to an output shaft of the first oscillating driving device 412, so that the first driving link 415 makes 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 rotation radius of the first driving link 415, and then can design a swing angle of the first oscillating fork 413.
The first oscillating fork 413 is provided with a first oscillating chute 4132 which is matched with the first driving connecting rod 415 so as to stir the first oscillating fork 413 to oscillate back and forth around the first oscillating shaft 416. During the swinging of the first oscillating fork 413, the first fork opening 4133 of the first oscillating fork 413 drives the biopsy instrument 10 to swing, so as to shake off the biopsy tissue.
Further, the first oscillating device 410 may further include a first driven link 414, and 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 with the swing arm. The first oscillating fork 413 is provided with a first auxiliary sliding groove 4131 engaged 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 due to the cooperation of the first driven link 414 and the first auxiliary sliding groove 4131.
It should be noted that the connection relationship among the components (the second oscillation mounting seat 421, the second oscillation driving device 422, the second oscillation fork 423, the second driven link 424, the second driving link 425, the second oscillation shaft 426, the second auxiliary link 4231, the second oscillation link 4232, and the second fork 4233) of the second oscillation device 420 and the components is the same as that of the first oscillation device 410, and the description thereof is omitted here.
In order to collect a plurality of biopsies, the tissue collection container 500 may comprise a container holder 502 and a plurality of collection tubes 501 fixed to the container holder 502, and the biopsies are collected through the collection tubes 501.
To ensure that the biopsy extraction channels 303 can correspond to individual collection tubes 501, the biopsy instrument 10 can be extended into the individual collection tubes 501 as desired. As shown in FIGS. 4 and 10, in one embodiment of the invention, the container support apparatus 600 includes a tissue container support base 605 and a displacement drive assembly. Wherein a tissue container support base 605 is slidably disposed on the base 104 of the holster 100, the tissue container support base 605 is configured to carry the tissue collection container 500.
The displacement drive assembly is used to drive the tissue container support base 605 to slide to switch different collection tubes 501 of the tissue collection container 500 to correspond with the biopsy instrument 10. For example, a first collection tube 501 of the tissue collection container 500 may be initially disposed opposite to the biopsy extraction channel 303, after the first collection tube 501 has taken the biopsy tissue, the tissue container support base 605 is pushed by the displacement driving assembly to move a set distance (i.e., the distance between two adjacent collection tubes 501), so that a second collection tube 501 of the tissue collection container 500 is disposed opposite to the biopsy extraction channel 303 to take the second biopsy tissue for collection, and after all the collection tubes 501 have taken the collection, the tissue collection container 500 is replaced with a new one.
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 the displacement mounting base 602, and the displacement driving device 601 may be a driving motor, and an output shaft thereof is disposed with a driving gear 603. A drive rack 604 is disposed on the tissue container support base 605 and is engaged with the drive gear 603.
