[0002] The tissue extraction and collection device can be used to collect tissue samples from living organisms such as the human body for subsequent pathological testing.

However, in the related art, the structural design of the driving mechanism and the reversing component is not reasonable, which makes the installation of the multi-channel mechanism relatively inconvenient.

[0004] Therefore, how to provide a solution to overcome or alleviate the above-mentioned defects is still a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0005] The utility model aims to provide a tissue extraction and collection device, which can simplify the installation of a multi-channel mechanism by arranging an elastic docking component.

[0006] To solve the above technical problems, the utility model provides a tissue extraction and collection device, comprising a frame, a driving mechanism and a multi-channel mechanism, wherein the driving mechanism and the multi-channel mechanism are both installed on the frame, the driving mechanism comprises a first docking component, the first docking component is configured to be driven to rotate, the multi-channel mechanism comprises a reversing component, the reversing component is connected to a second docking component; one of the first docking component and the second docking component is provided with a docking protrusion, and the other is provided with a docking recess, and when the docking protrusion is inserted into the docking recess, the first docking component and the second docking component can rotate synchronously; at least one of the first docking component and the second docking component is an elastic docking component, and the elastic docking component comprises a shaft, an elastic member and a first docking member, the first docking member is configured to be able to slide along the shaft and to rotate synchronously with the shaft, one end of the elastic member is fixed, and the other end of the elastic member is against the first docking member, and the first docking member is provided with the docking protrusion or the docking recess.

[0041] like Figure 1As shown, an embodiment of the utility model provides a tissue extraction and collection device, including a frame 1, a driving mechanism 2, a multi-channel mechanism 3, an oscillating mechanism 4 and a collection mechanism 5.

[0042] The frame 1 is the structural basis of the tissue extraction and collection device, and is used to provide installation positions for other mechanisms, such as the above-mentioned driving mechanism 2, multi-channel mechanism 3, oscillation mechanism 4 and collection mechanism 5 can be directly or indirectly installed on the frame 1. Here, the embodiment of the utility model does not actually make any special restrictions on the specific structure of the frame 1. During the specific implementation, those skilled in the art can determine it in combination with actual needs.

[0043] In a specific example, Figure 1 As shown, the frame 1 may include a base plate 11, a reversing seat 12 and a bottom plate 13. The reversing seat 12 and the bottom plate 13 may be located on the same side of the base plate 11, and the reversing seat 12 may be located on the upper side of the bottom plate 13. The multi-channel mechanism 3 may be mounted on the reversing seat 12, the oscillating mechanism 4 may be mounted on the base plate 11, the collecting mechanism 5 may be mounted on the bottom plate 13, and the driving mechanism 2 may be partially mounted on the base plate 11 and the other partially mounted on the bottom plate 13. For details, please refer to the following description.

[0044] The driving mechanism 2 includes a first driving component 21 and a first docking component 22 .

[0045] The first driving component 21 can be a driving element such as a motor or a rotary cylinder that can output a rotational displacement, so as to drive the first docking component 22 to rotate. The first driving component 21 can be directly connected to the first docking component 22; or the first driving component 21 can be indirectly connected to the first docking component 22 by means of a transmission structure in the form of a pulley structure, a gear structure, a sprocket structure, etc. Figure 4 and Figure 5 As shown, the first driving component 21 and the first docking component 22 can be driven by means of a pulley 23 and a belt 24. In this implementation, the installation position of the first driving component 21 can be conveniently adjusted by adjusting the length of the belt 24. For example, the first driving component 21 can be set relatively far away from the first docking component 22. In this way, both the first driving component 21 and the first docking component 22 can have a relatively large installation space, so that they can be easily installed.

[0046] Combination Figure 4, the first driving component 21 can be installed on the base plate 11 with the help of the first connecting frame 211. In addition, the first connecting frame 211 can also be configured with a long strip adjustment hole 211a. By adjusting the position of the connecting member in the form of a screw or the like in the adjustment hole 211a, the installation position of the first connecting frame 211 on the base plate 11 can be conveniently adjusted, thereby adjusting the tightness of the belt 24. The first driving component 21 and the reversing seat 12 can be located on both sides of the base plate 11 respectively, so that the space on both sides of the base plate 11 can be more fully utilized.

[0047] like Figure 5 and Figure 6 As shown, the first docking component 22 may be an elastic docking component, including a shaft body (driving shaft 221 ), an elastic member 222 and a first docking member 223 .

[0048] The drive shaft 221 can be installed with the aid of bearings 221c, bearing seats 221d, etc., so as to construct a stable transmission shaft system. The first docking piece 223 is configured to be able to slide along the drive shaft 221 and to rotate synchronously with the drive shaft 221. Specifically, the drive shaft 221 can have a matching shaft section, and the first docking piece 223 can have a matching hole section. The first docking piece 223 can be sleeved on the matching shaft section of the drive shaft 221 through the matching hole section. The cross-sections of the matching shaft section and the matching hole section perpendicular to the axial direction are both non-circular, such as elliptical, cross-shaped, quadrilateral, gear ring-shaped or other special shapes, etc. In this way, the purpose of the first docking piece 223 being able to slide relative to the drive shaft 221 and the two being able to rotate synchronously can be achieved.

[0049] The elastic member 222 can be specifically a spring. There are many types of springs, with complete models. It is relatively easy to obtain and select springs, and they have good elastic deformation and reset capabilities. In addition, the elastic member 222 can also be an elastomer made of rubber or other materials with certain flexible deformation capabilities. Taking a spring as an example, the elastic member 222 can be assembled on the drive shaft 221 in a jacket, and one end of the elastic member 222 can be fixed, for example, it can be fixed by abutting against the drive shaft 221, and the other end of the elastic member 222 can abut against the first docking member 223.

[0050] In practical applications, if the first docking member 223 is subjected to an external force in the axial direction, the first docking member 223 may be axially displaced along the drive shaft 221, and the deformation amount of the elastic member 222 may increase to accumulate elastic potential energy, and when the external force acting on the first docking member 223 disappears or weakens, the elastic potential energy accumulated by the elastic member 222 may be released to drive the first docking member 223 to reset. It should be noted that in this process, the first docking member 223 and the drive shaft 221 may rotate synchronously.

[0051] Still Figure 6 As shown, the drive shaft 221 can be a split structure, including a shaft body 221a and a stopper 221b, and the stopper 221b can be fixedly assembled on the shaft body 221a by interference press fitting, welding, etc. The stopper 221b can be formed with the aforementioned matching shaft section, and the first docking member 223 can specifically slide along the stopper 221b and can rotate synchronously with the stopper 221b, and the two ends of the elastic member 222 can be respectively abutted against the stopper 221b and the first docking member 223. With this solution, since the stopper 221b with the matching shaft section is an independent component, it can be easily processed and prepared.

[0052] It should be understood that in practical applications, the stopper 221b and the shaft body 221a may be integrally formed, so that the number of parts of the first docking component 22 may be relatively small and the assembly process may be relatively simple. For example, when the drive shaft 221 and the first docking component 223 are spline-matched, the drive shaft 221 may be a spline shaft, and the outer wall surface of the mating shaft section may be provided with spline teeth, and the first docking component 223 may be a spline sleeve, and the inner wall surface may be formed with spline grooves. Through the cooperation of the spline teeth and the spline grooves, the relative displacement of the drive shaft 221 and the first docking component 223 in the axial direction and the synchronous rotation in the circumferential direction may be achieved.

[0053] The first docking member 223 may be provided with a docking protrusion 223 a.

[0054] The multi-channel mechanism 3 may include a main body 31 and a reversing component 32. A plurality of channels are formed in the main body 31, the reversing component 32 is disposed in the main body 31, and the main body 31 is configured to be rotatable in the main body 31 so as to adjust the connection state between different channels, thereby better realizing the function of the tissue extraction and collection device.

[0055] Here, the embodiment of the utility model does not limit the number of passages in the main body 31 and the specific structural form of the reversing component 32. In practical applications, those skilled in the art can choose according to actual needs. For example, the main body 31 can be provided with three passages (in this case, the main body 31 is similar to the function of a three-way valve), or four passages (in this case, the main body 31 is similar to the function of a four-way valve), etc.

[0056] In the implementation of the accompanying drawings, Figure 3As shown, three passages can be provided in the main body 31. For the convenience of description, these three passages can be respectively referred to as the first passage 311, the second passage 312 and the third passage 313, wherein the third passage 313 directly points to the collecting mechanism 5. The reversing component 32 can be provided at the intersection of the three passages. By adjusting the posture of the reversing component 32 in the main body 31, the main body 31 can have a first connected state and a second connected state. In the first connected state, the first passage 311 and the second passage 312 can be connected. This connected state can be seen in FIG. Figure 3 , which can be used to introduce flexible medical instruments (such as biopsy forceps, biopsy needles, etc.) into living bodies such as human bodies to extract tissue samples. In the second connection state, the first passage 311 and the third passage 313 can be connected. This connection state is suitable for extending the medical instrument through the third passage 313 into the collection mechanism 5 to collect the tissue samples extracted by the medical instrument.

[0057] The reversing component 32 may be connected to a second docking component 33 , and the second docking component 33 is configured to drive the reversing component 32 to rotate.

[0058] Combination Figure 6 The second docking member 33 may include a second docking member 331 and a connecting shaft 332. The second docking member 331 and the aforementioned reversing member 32 may be fixedly assembled on the connecting shaft 332. In this way, the second docking member 331 can drive the reversing member 32 to rotate synchronously through the connecting shaft 332, and the connection structure is simple. In addition, a transmission structure in the form of a pulley structure, a gear structure, a sprocket structure, etc. may also be provided between the second docking member 331 and the reversing member 32, as long as it can realize the power transmission between the second docking member 331 and the reversing member 32.

[0059] The second docking member 331 may be provided with a docking recess 331 a .

[0060] When the docking protrusion 223a is inserted into the docking recess 331a, the first docking component 22 and the second docking component 33 can rotate synchronously. In this way, the power of the first driving component 21 can be transmitted to the reversing component 32 to drive the reversing component 32 to rotate automatically, thereby realizing the switching of the connection state of the multi-channel mechanism 3; and, since the driving force is provided by the first driving component 21, the labor intensity of the staff is relatively low. It should be understood that in actual use, the aforementioned first driving component 21 may not be provided. In this case, the driving and rotation of the first docking component 22 can be completed manually by the staff. Although the labor intensity of the staff will increase, the structure of the tissue extraction and collection device can be greatly simplified.

[0061] Here, the embodiment of the utility model does not limit the structural shape of the docking protrusion 223a and the docking recess 331a. In practical applications, those skilled in the art can set them according to specific needs as long as reliable power transmission between the first docking component 22 and the second docking component 33 can be guaranteed.

[0062] In fact, the structural shape of the docking protrusion 223a and the docking recess 331a is related to the number and matching method of the two. For example, when the docking protrusion 223a and the docking recess 331a are in a one-to-one plug-in matching relationship, if the number of the docking protrusion 223a and the docking recess 331a is one, it is necessary to set the cross-section of the docking protrusion 223a and the docking recess 331a perpendicular to the axial direction to be non-circular, and if the number of the docking protrusion 223a and the docking recess 331a is two or more, the shape of the two can be unrestricted. For another example, when the docking protrusion 223a and the docking recess 331a are in a many-to-one plug-in matching relationship, the docking recess 331a can be set to a long strip, and multiple docking protrusions 223a can be arranged along a straight line and can be plugged into the long strip of docking recess 331a.

[0063] It should be understood that the positions of the docking protrusion 223a and the docking recess 331a can also be reversed, that is, the docking protrusion 223a can be arranged on the second docking component 33, and the docking recess 331a can be arranged on the first docking component 22, which is also feasible. For ease of description, the following embodiments of the utility model are all described by taking the docking protrusion 223a arranged on the first docking component 22 and the docking recess 331a arranged on the second docking component 33 as an example.

[0064] In the related art, both the first docking component and the second docking component are non-elastic docking components. When the multi-channel mechanism is installed on the frame, the first docking component or the second docking component needs to be adjusted so that the docking protrusion can be accurately inserted into the docking recess, which makes the installation process of the multi-channel mechanism cumbersome and relatively inconvenient.

[0065] However, in the embodiment of the utility model, the first docking component 22 is an elastic docking component. During the specific assembly, if the docking protrusion 223a is not inserted into the docking recess 331a, under the action of the second docking component 33, the first docking component 223 will slide and retract along the drive shaft 221, and will not cause the multi-channel mechanism 3 to be unable to be installed. In this process, the elastic component 222 can accumulate elastic potential energy; after the multi-channel mechanism 3 is installed, a rotational driving force is directly applied to the first docking component 22, that is, the first docking component 223 can be rotated relative to the second docking component 33. During the relative rotation of the two, there is a moment when the docking protrusion 223a can be aligned with the docking recess 331a. At this time, the elastic potential energy accumulated by the elastic component 222 can be released, and the docking protrusion 223a can be automatically inserted into the docking recess 331a, thereby realizing the dynamic connection between the first docking component 22 and the second docking component 33, and will not affect the use of the multi-channel mechanism 3. Therefore, by setting the elastic docking component, the embodiment of the utility model can make the installation of the multi-channel mechanism 3 simple.

[0066] Furthermore, when the first docking component 22 is an elastic docking component and the second docking component 33 is a non-elastic docking component, the structure of the multi-channel mechanism 3 can be simplified. In practical applications, in order to prevent cross infection, the multi-channel mechanism 3 may be used as a consumable and discarded after one use. Therefore, the simplification of the structure of the multi-channel mechanism 3 can greatly reduce the use cost of the tissue extraction and collection device provided by the embodiment of the utility model.

[0067] It should be understood that during the specific assembly, the staff can accurately judge the matching condition of the docking protrusion 223a and the docking recess 331a based on the resistance of the multi-channel mechanism 3 during the installation process; if the docking protrusion 223a is not inserted into the docking recess 331a, the first docking component 22 can be driven. During the driving process, if a "pop" collision sound is heard, it indicates that the docking protrusion 223a is inserted into the docking recess 331a under the action of the elastic member 222.

[0068] In practical applications, the second docking component 33 may be set as an elastic docking component, or the first docking component 22 and the second docking component 33 may be both set as elastic docking components, which can also achieve the above technical purpose. It should be noted that when the second docking component 33 is an elastic docking component, the shaft body of the elastic docking component may be a connecting shaft 332.

[0069] In some optional implementations, the tissue extraction and collection device provided by the embodiments of the present utility model may further include an elastic latch.

[0070] The elastic latch may include a collision boss 35 and a collision lock seat, wherein an elastic collision ball is arranged in the collision lock seat; one of the collision boss 35 and the collision lock seat may be installed on the multi-channel mechanism 3, and the other may be installed on the frame 1. With this solution, when the multi-channel mechanism 3 is installed on the frame 1, the collision boss 35 and the elastic collision ball of the collision lock seat may be constrained, thereby realizing the rapid assembly between the multi-channel mechanism 3 and the frame 1. At the same time, when a large external force is applied to the elastic latch, the collision boss 35 and the collision lock seat may be separated, which is also conducive to the rapid disassembly of the multi-channel mechanism 3 and the frame 1.

[0071] It should be understood that the multi-channel mechanism 3 and the rack 1 can actually be locked by other connection methods, such as a snap-on structure, a screw hole structure, etc., which are not actually limited here, as long as the reliability requirements and detachability requirements of the connection can be met.

[0072] In some optional implementations, at least one of the rack 1 and the multi-channel mechanism 3 may be provided with a sensing module 34 and an identification component (not shown in the figure).

[0073] The sensing module 34 may be a proximity light sensor, a distance sensor, a travel switch, etc., which is configured to sense whether the multi-channel mechanism 3 and the rack 1 are installed in place. The identification component and the sensing module 34 may be communicatively connected, and the identification component may be configured to at least provide a prompt identification when the multi-channel mechanism 3 and the rack 1 are installed in place.

[0074] The identification component may specifically be an indicator light, and in this case, the prompt mark may be a mark of a lighted indicator light or a light mark of a specific color. For example, when the indicator light is not installed in place, it may be off, and when it is installed in place, it may be lit. For another example, the indicator light may be always on, but in different states, it may emit light of different colors, such as emitting red light when it is not installed in place, and emitting green light when it is installed in place.

[0075] In fact, the identification component may also be other electronic modules, and the prompt identification provided by the identification component may be a text identification displayed on a display screen, etc.

[0076] like Figure 5 and Figure 7 As shown, the oscillation mechanism 4 can be located below the multi-channel mechanism 3, and includes an oscillation applying part 41, which is used to apply an oscillation force to the medical device inserted into the collection mechanism 5, so that the tissue sample extracted by the medical device can be shaken into the collection mechanism 5. The oscillation applying part 41 can directly interact with the medical device. Alternatively, the oscillation applying part 41 can also indirectly interact with the medical device. Figure 1An oscillation tube 36 may be connected to the bottom of the multi-channel mechanism 3, and the medical device may extend into the collecting mechanism 5 through the oscillation tube 36. The oscillation applying part 41 may apply an oscillation force to the medical device through the oscillation tube 36, thereby avoiding direct contact between the oscillation applying part 41 and the medical device, and avoiding contamination of the collected tissue samples to a large extent.

[0077] The oscillation applying part 41 may be specifically an oscillation fork, including a fork head 411 and a fork rod 412. The aforementioned oscillation tube 36 may be inserted into the fork head 411. The fork rod 412 may be rotatably assembled, and the fork rod 412 may be provided with a transmission hole 412a, which may be a bar-shaped hole.

[0078] In the embodiment of the utility model, the driving mechanism 2 may further include a second driving component 25 and an oscillation driving unit 26. The second driving component 25 is configured to drive the oscillation driving unit 26 to operate, and the oscillation driving unit 26 is configured to drive the oscillation applying unit 41 to operate, so as to apply an oscillating force to the medical device.

[0079] In some implementations, the second drive component 25 can be used to output linear displacement to drive the oscillation drive unit 26 to perform linear displacement. The oscillation drive unit 26 can be specifically a rod, etc., which can be inserted into the transmission hole 412a to drive the oscillation applying unit 41 to swing. In one example, the second drive component 25 can be a linear cylinder, a linear oil cylinder, or other drive element that can directly output linear displacement, so as to simplify the structure. In another example, the second drive component 25 can also be a motor, a rotary cylinder, or other drive element that can output rotational displacement. In this case, the second drive component 25 can also be equipped with a displacement conversion mechanism in the form of a gear rack mechanism, a screw mechanism, etc., so as to convert the rotational displacement directly output by the second drive component 25 into a linear displacement.

[0080] In other implementations, the second driving component 25 can be used to output rotational displacement to drive the oscillation driving part 26 to perform rotational displacement. At this time, the oscillation driving part 26 can be provided with an eccentric wheel 261, and the eccentric wheel 261 can be located in the transmission hole 412a. During the rotation of the eccentric wheel 261, the oscillation applying part 41 can also be driven to swing.

[0081] This implementation can be seen in Figure 4 and Figure 5 The second driving component 25 may also be configured with a second connecting frame 251 , and the second driving component 25 may be installed on the substrate 11 through the second connecting frame 251 .

[0082] The second drive component 25 and the oscillation drive unit 26 can be connected by a coupling 27 to improve the compactness of the device. Of course, the second drive component 25 and the oscillation drive unit 26 can also be connected by a transmission structure in the form of a pulley structure, a gear structure, a sprocket structure, etc., which is also feasible.

[0083] Furthermore, the second driving component 25 may also be configured with a control module 42, and the control module 42 may be configured to control the stop position of the oscillation driving component 26 through the second driving component 25, that is, to control the stop position of the oscillation applying component 41. For example, the oscillation applying component 41 may be stopped at a position where it does not contact the oscillation tube 36, so as to avoid the oscillation applying component 41 continuously exerting force on the oscillation tube 36 when the device is not in use, thereby affecting the reliability of the connection of the oscillation tube 36 to the main body 31. For another example, for a solution in which the oscillation tube 36 is not provided, the oscillation applying component 41 may be stopped at a position where it does not interfere with the medical device, so as to avoid interfering with the process of the medical device extending into the collection mechanism 5.

[0084] The control module 42 may specifically be a servo, an encoder, a photoelectric sensor, etc.

[0085] Furthermore, the tissue extraction and collection device provided in the embodiment of the utility model may further include a base 43. The base 43 may be mounted on the frame 1, and the control module 42 and the oscillation driving unit 26 may both be mounted on the base 43.

[0086] Specifically, if Figure 8 As shown, combined with Figure 5 The base 43 may be provided with a first mounting portion 431 , a second mounting portion 432 and a connecting hole 433 , the control module 42 may be assembled on the first mounting portion 431 , the oscillation driving portion 26 may be mounted on the second mounting portion 432 , and the base 43 may be connected to the substrate 11 through the connecting hole 433 .

[0087] In some optional implementations, the collecting mechanism 5 may include at least one collecting component 51 and a blocking component 52 .

[0088] The collecting component 51 may be, for example, a test tube, a storage bottle, etc., for storing tissue samples extracted by medical devices. There is also liquid in the collecting component 51 in the form of a preservation liquid. The collecting component 51 may have an opening, and the aforementioned blocking component 52 is configured to be able to block the opening, so that leakage of the liquid in the collecting component 51 can be prevented. When it is necessary to collect tissue samples, the aforementioned blocking component 52 can be removed to expose the opening of the collecting component 51, thereby facilitating the insertion of medical devices.

[0089] like Fig. 9As shown, the collecting mechanism 5 may further include a supporting component 53, which is configured to support the collecting component 51; for example, when the collecting component 51 is a test tube, the supporting component 53 may be a test tube rack, on which multiple test tubes may be placed, or of course only one test tube may be placed.

[0090] The blocking component 52 may include an upper isolation cover 521, a lower isolation cover 522 and an isolation sheet 523. The isolation sheet 523 may be disposed between the upper isolation cover 521 and the lower isolation cover 522, and the isolation sheet 523 is used to block the opening of the collecting component 51. The upper isolation cover 521 and the lower isolation cover 522 may be connected to each other, and at least one of the upper isolation cover 521 and the lower isolation cover 522 may be detachably connected to the supporting component 53 to achieve the connection between the blocking component 52 and the supporting component 53, and the specific connection method includes but is not limited to a snap connection, a screw connection, and the aforementioned elastic latch connection, etc., to facilitate the connection and disassembly of the blocking component 52 and the supporting component 53.

[0091] It should be understood that the above-mentioned scheme including the upper isolation cover 521, the lower isolation cover 522 and the isolation plate 523 is only an exemplary description of the specific structural description of the sealing component 52 in the embodiment of the utility model, and it cannot be used as a limitation on the scope of implementation of the tissue extraction and collection device provided by the embodiment of the utility model. Under the condition of satisfying the functions, the above-mentioned sealing component 52 can also adopt other structural forms. For example, the sealing component 52 can be a plug, etc.

[0092] The number of the collecting components 51 may be one, or the number of the collecting components 51 may be multiple. When there are multiple collecting components 51, the collecting mechanism 5 may further include a driving tray 54, and the supporting component 53 may be mounted on the driving tray 54. By applying a driving force to the driving tray 54, the supporting component 53 may be driven to rotate, thereby achieving the technical purpose of collecting tissue samples in different collecting components 51.

[0093] The driving tray 54 can be driven manually by a worker, so that the structure of the collecting mechanism 5 can be relatively simple.

[0094] Alternatively, the driving mechanism 2 may further include a third driving component 28, which may be mounted on the bottom plate 13, and the third driving component 28 may be configured to drive the driving tray 54 to rotate so as to switch between different collecting components 51. In this implementation, since the driving force is provided by the third driving component 28, the labor intensity of the staff is relatively low, and the degree of automation of the equipment may also be high.

[0095] The third driving component 28 may be configured with a third connecting frame 281 , and the third driving component 28 may be mounted on the bottom plate 13 through the third connecting frame 281 .

[0096] Further, the bottom plate 13 may be provided with a retaining ring 55, the driving tray 54 may be located inside the retaining ring 55, and a sealing member 56 may be provided between the driving tray 54 and the retaining ring 55. The sealing member 56 may be, for example, a sealing ring made of a material having a certain flexibility and deformation ability, such as rubber, etc., and is used to block the gap between the retaining ring 55 and the driving tray 54, thereby preventing external impurities such as water vapor and dust from affecting the normal operation of the connection structure between the driving tray 54 and the third driving component 28.

[0097] The above are only preferred implementations of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
