Description

Technical Field

[0001] The present invention belongs to the technical field of biological diagnostic instruments, and particularly relates to a device for collecting fecal samples from livestock in vivo for animal husbandry and veterinary medicine. Background Art

[0002] Veterinary medicine is a relatively crucial guarantee industry in livestock farming. Especially in the field of mammalian breeding, once an epidemic or disease occurs in livestock, it will cause serious harm to the breeding benefits. When veterinarians carry out animal health care, they not only need relevant pathological diagnosis bases but also corresponding diagnostic equipment for auxiliary diagnostic work.

[0003] The existing Chinese utility model patent with the publication number CN220109766U discloses a device for collecting samples of animal husbandry and veterinary diseases. Before diagnosing livestock gastroenteritis, parasite infection, intestinal mucosa bleeding, etc., fecal sampling is required for subsequent tests to assist in the diagnosis of the disease. For the disclosed sampling device, since there are requirements for the depth of fecal sampling, an insertion mechanism is designed to specifically sample feces in the deep layer of the intestine. However, the intestine has a bending angle, and the rigid structure of its insertion mechanism cannot adapt to the bending amplitude of the intestine and penetrate through the bent position of the intestine. Fecal sampling is a blind sampling operation, and during the deep sampling process, it is easy to cause stress bleeding of the intestinal mucosa, resulting in blood in the sample, and it is impossible to determine whether the bleeding in the feces is caused by the disease or the sampling. As a result, the diagnostic result will deviate due to problems with the sample. In view of this, a device for collecting fecal samples from livestock in vivo for animal husbandry and veterinary medicine is provided. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned disadvantages of the prior art and provide a device for collecting fecal samples from livestock in vivo for animal husbandry and veterinary medicine.

[0005] The technical solution adopted to solve the above technical problem is as follows:

[0006] A device for collecting fecal samples from livestock in vivo for animal husbandry and veterinary medicine, comprising:

[0007] A grip, the grip includes a holding tube, a relay member is installed at the end of the holding tube, and a thumb rest is rotatably sleeved on the outer side of one end of the holding tube connecting the relay member;

[0008] An extension member, the extension member includes a tapered spiral section, the large-diameter end of the tapered spiral section is fixedly connected to the relay member, the small-diameter end of the tapered spiral section is connected to an equidistant spiral section with the same diameter, and a mounting seat is fixed at the free end of the equidistant spiral section;

[0009] A commutator, the commutator includes four drawstrings, the four drawstrings are annularly arrayed with the axis of the mounting base as the center, the free ends of the drawstrings are provided with actuating members, and the actuating members are mounted at the position of the holding cylinder;

[0010] A sampling member, the sampling member includes a through cylinder, the through cylinder is detachably mounted at the free end of the mounting base, the through cylinder is internally provided with a through diagnostic sample cavity, the end of the through cylinder away from the mounting base is provided with an inner folding edge, and a first baffle and a second baffle arranged in a staggered manner are mounted at the inner folding edge;

[0011] A sliding plate, the sliding plate includes a net disk coaxially arranged with the through cylinder, a check valve II is mounted at the center position of the net disk, a telescopic member is connected to the end of the check valve II facing the mounting base, and the telescopic member is connected to a gas source through an air pipe.

[0012] Further, the telescopic member includes an elastic member, a sleeve is sleeved outside the elastic member, the sleeve is fixedly mounted between the check valve II and the air outlet end of the air pipe, and both ends of the elastic member are fixedly mounted with the check valve II and the air pipe respectively.

[0013] Through the above technical solution, the specific configuration of the telescopic member is disclosed. Before the extension member pushes the sampling member to the sampling position, the gas source supplies gas to the telescopic member. The check valve II prevents the gas in the telescopic member from flowing into the sampling member. The sleeve is inflated and elongated to block the sliding plate at the deformed positions of the first baffle and the second baffle, preventing feces at non-lesion positions from entering the sampling member. After reaching the lesion position or sampling depth, the gas source evacuates the telescopic member. The air in the sampling member enters the sleeve through the check valve II. The telescopic member shortens and the sliding plate disengages from the first baffle and the second baffle. The first baffle and the second baffle can swing towards the diagnostic sample cavity of the sampling member, enabling the feces sample to enter the diagnostic sample cavity. Continuously evacuating the air in the sampling member through the telescopic member keeps the sampling member in a negative pressure state, and can also improve the sampling efficiency for thin and runny feces samples.

[0014] Further, an outer ring is fixedly mounted on the circumferential outer wall of the net disk, a receiving cavity is provided on the side of the mounting base facing the sliding plate, the inner wall of the receiving cavity is frustum-shaped, the outer diameter of the outer ring is smaller than the inner diameter of the opening of the receiving cavity, and the telescopic member is coiled in the receiving cavity.

[0015] Through the above technical solution, to ensure the smooth progress of negative pressure sampling, after the telescopic member is evacuated, the elastic member that elongates and stores energy will rebound, coiling the telescopic member in the receiving cavity. At the same time, the elastic force of the elastic member will pull the sliding plate into the receiving cavity and cooperate with the special-shaped opening of the receiving cavity to prevent feces samples from entering the receiving cavity and the check valve II, ensuring that the sleeve will not be flattened and affect gas passage, and also preventing the check valve II from being blocked by feces, and can continuously evacuate the gas in the sampling member.

[0016] Further, the air source includes a handball, the handball has two air passing ports equipped with check valves I, one of the air passing ports of the handball is detachably connected with a hose, and the hose is cooperatively inserted with the air inlet end of the air pipe.

[0017] Through the above technical solution, the specific configuration of the air source is disclosed. By using a squeezable handball in combination with check valve I, the handball functions as a one-way gas pump. Specifically, when the handball is squeezed, the gas inside the handball is extruded from the air passing port at the left end. When relaxed, the outside air enters the handball from the air passing port at the right end. When it is necessary to inflate the telescopic member, the air outlet port of the handball is connected to the air inlet end of the air pipe through the hose for continuous pressing inflation. Similarly, when it is necessary to exhaust air from the sampling member, the air inlet port of the handball is connected to the air inlet end of the air pipe through the hose for continuous pressing exhaust.

[0018] Further, both the pull rope and the air pipe are arranged in the through space in the middle of the equidistant spiral section and the conical spiral section. Through holes for cooperating with the pull rope and the air pipe are respectively formed in the relay member. A skin is sleeved and installed between the relay member and the mounting seat on the outside of the equidistant spiral section and the conical spiral section.

[0019] Through the above technical solution, to ensure the smooth change of the advancing direction of the sampling member, the pull rope for adjusting the advancing direction of the sampling member is placed in the equidistant spiral section and the conical spiral section, and the skin can be used to resist the extrusion of the outside world on the pull rope, ensuring that the pull rope can still be smoothly pulled after the extension member enters the livestock intestine and ensuring the flexibility of the operation.

[0020] Further, there are four actuating members, and the four actuating members are sequentially fixed on the inner wall of the circumference of the holding cylinder along the axial direction of the holding cylinder. The actuating members are arranged in a staggered manner. The actuating member includes a limiting frame. A sliding frame is slidably installed in the limiting frame along the radial direction of the holding cylinder. A wedge block is slidably installed in the limiting frame along the axial direction of the holding cylinder. The wedge block is fixedly connected with the pull rope. The opposite sides of the sliding frame and the wedge block are respectively provided with a first inclined surface and a second inclined surface. One ends of the first inclined surface and the second inclined surface away from the pull rope are inclined towards the inner wall of the circumference of the holding cylinder.

[0021] Through the above technical solution, the specific configuration of the actuating member is disclosed. The four actuating members are arranged in a staggered manner corresponding to the four fingers holding the holding cylinder. In this way, the sliding frame can be pressed by the four fingers to squeeze the wedge block and pull the pull rope, so as to realize the control of the advancing direction of the sampling member and manually control it to quickly penetrate into the sampling position.

[0022] Further, a convex strip is provided at one end of the sliding frame facing the inner wall of the circumference of the holding cylinder. A contact piece is embedded and installed at the position of the holding cylinder corresponding to the convex strip. A support strip is arranged along the radial direction of the holding cylinder on the sliding frame. Sockets are formed in the limiting frame corresponding to the positions of the sliding frame and the support strip.

[0023] Through the above technical solution, in order to increase the operation convenience of the moving part, a rib is provided at one end of the carriage that is squeezed by the finger, so as to connect a contact piece with a larger area. In this way, the carriage can be slid by squeezing the contact piece, reducing the precision required for pressing the carriage operation. Moreover, the rib and the limiting frame are slidably connected along the radial direction of the holding cylinder to play a role in limiting the carriage, preventing the carriage from axially moving along the holding cylinder and causing the pressing of the carriage to be unable to squeeze the wedge block to slide axially along the holding cylinder. Furthermore, by improving the structural stability, the operation is made simpler.

[0024] Furthermore, a adapter is provided at one end of the holding cylinder connected to the relay member. A collar is sleeved outside the adapter. A thumb rest is fixed on the circumferential outer wall of the collar. A sliding groove corresponding to the position of the contact piece is opened on the circumferential inner wall of the collar. The starting end of the sliding groove is located at the farthest position of the collar from the thumb rest. A limiting block is fixedly installed at the starting end of the sliding groove of the adapter. A first convex key and a second convex key that cooperate with the limiting block are respectively provided at the starting end and the ending end of the sliding groove.

[0025] Through the above technical solution, for the convenience of different doctors to use, when a left-handed doctor uses it, the limiting block can be stuck at the position of the first convex key. At this time, the thumb is sleeved in the thumb rest to play a role in increasing the auxiliary holding point. The other four fingers can gently hold the holding cylinder, and the distal phalanx corresponds to the upper edge position of the four contact pieces, so as to more conveniently hold and release to control the four moving parts by the four fingers. When a right-handed doctor uses it, the thumb rest rotates 90 degrees relative to the holding cylinder, and the limiting block can be stuck at the position of the second convex key. At this time, the lower edge position of the four contact pieces is raised to the same height as the original upper edge position, that is, after the thumb extends into the thumb rest, the distal phalanx can still correspond to the raised lower edge position of the four contact pieces, which is also convenient for the operation and control of the four moving parts.

[0026] Furthermore, an avoidance opening is provided on the side of the carriage facing the wedge block. The avoidance opening penetrates the carriage along the axial direction of the holding cylinder, and the inner width of the avoidance opening is greater than the outer diameter of the pull rope.

[0027] Through the above technical solution, in order to improve the use stability of the commutator, pressing the carriage to move it towards the axis of the holding cylinder will cause the carriage to approach the pull rope. Therefore, in order to prevent the carriage and the pull rope from rubbing against each other, an avoidance opening is provided at the position of the carriage facing the pull rope, so that the carriage will not contact the pull rope during the pressing and resetting processes, ensuring the stability during long-term use.

[0028] Furthermore, a mounting hole is opened on the mounting seat, and a visual module is installed in the mounting hole. The wire of the visual module extends to the position of the relay member along the extension member, and the plug of the visual module is embedded and installed on the circumferential outer wall of the relay member.

[0029] Through the above technical solution, the visual module can adopt a micro camera for endoscope, which can facilitate endoscope observation, so that the sampling piece can reach the lesion position more accurately for sampling, and can also observe the internal situation of the livestock intestine in real time to control the sampling progress and prevent secondary damage caused by sampling.

[0030] The beneficial effects of the present invention are as follows:

[0031] (1) Through the settings of the grip, extension piece, commutator, sampling piece and slide plate, the present invention can use the commutator to bend the extension piece directionally, pass the sampling piece through the bent position of the intestine, and smoothly send it to the deeper part of the intestine for deep in-vivo fecal sampling, and provide a more real diagnostic sample for subsequent diagnostic tests. At the same time, optimizing the structure of the sampling piece can meet different sampling requirements for hard feces and runny feces. Cooperating with the slide plate can also prevent feces from entering the sampling piece during the deepening path of the sampling piece, ensuring the accuracy of the sampling position.

[0032] (2) Through the optimization of the first baffle, the second baffle, the telescopic piece and the air source, the present invention uses the air source to inflate the telescopic piece to make it elongate, and then the slide plate can be pressed on the middle part of the baffle at the sampling piece inlet position, cooperating to block the sampling piece inlet in the path and prevent accidental sampling during the insertion process. When the telescopic piece exhausts air and shortens to reset, the sampling can proceed smoothly, and negative pressure suction can also be generated to assist in the smooth sampling of runny samples, improving the sampling adaptability.

Detailed implementation manners

[0045] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0046] As Figure 1 - Figure 11 shown, this embodiment provides a livestock internal feces sample collection device for livestock veterinarians. In actual diagnostic sampling use, to overcome the actual problems existing in the prior art, ensure that the feces samples taken are closer to the actual lesion state, avoid bleeding caused by sampling, and reduce the deviation in later pathological diagnosis caused by the fact that the samples taken are a mixture of feces at different time periods in the intestine, a specific feces sampling configuration is provided for accurate livestock pathological diagnosis and testing. Specifically, it includes a grip 1. Among them, the grip 1 includes a holding tube 11, and the holding tube 11 is a hollow cylindrical tube. Refer to Figure 1 and Figure 4, a relay member 13 is installed at the end of the holding tube 11. The relay member 13 and the holding tube 11 are designed and assembled separately to connect the holding tube 11 with the extension member 2. Moreover, when the user holds the holding tube 11, the palm and four fingers hold the holding tube 11, and a thumb seat 12 is rotatably sleeved outside one end of the holding tube 11 connected to the relay member 13. The thumb is inserted into the thumb seat 12 to provide an auxiliary holding point, which is more convenient for exerting force and holding the whole device during sampling;

[0047] Regarding the extension member 2, refer to Figure 3 and Figure 4 , the extension member 2 includes an elastic tapered spiral section 23. The tapered spiral section 23 is a single-piece tower-shaped spring that can be bent under force after entering the intestine to adapt to the bending of the intestine. Moreover, the large-diameter end of the tapered spiral section 23 is fixedly connected to the relay member 13, that is, the diameter narrows as it moves away from the holding tube 11, so that its free end is easier to be bent. Further, the small-diameter end of the tapered spiral section 23 is connected to an equidistant spiral section 22 with the same diameter. The equidistant spiral section 22 uses a uniform spring with a smaller wire diameter, which is easier to be bent under force and more adaptable to the bending changes of the livestock intestine, so as to more smoothly insert into the lesion position deeper in the intestine for direct sampling. The fecal samples taken are closer to the actual disease state than the feces near the anus or discharged out of the body. The free end of the equidistant spiral section 22 is fixed with a mounting seat 21 to install the sampling member 3 at the end of the extension member 2 that can be flexibly reoriented;

[0048] Regarding the commutator 6, refer to Figure 3 , the commutator 6 is used to bend the free end of the extension member 2 so that the orientation of the sampling member 3 can be flexibly changed, and thus it can be taken through the bent intestine. Specifically, the commutator 6 includes four pull ropes 61, and the four pull ropes 61 are annularly arranged around the axis of the mounting seat 21. In this way, by axially pulling one of the pull ropes 61, the sampling member 3 can be swung in the direction of the pull rope 61. The four pull ropes 61 are arranged at intervals of ninety degrees and can also be independently pulled by different distances, so that the 360-degree swing control of the advancing direction of the sampling member 3 can be carried out, and it can smoothly penetrate deep along the bent intestine. The free end of the pull rope 61 is installed with an actuating member 62 to provide horizontal pulling power for the pull rope 61. Here, the actuating member 62 can be an axially arranged electric telescopic rod or a micro telescopic cylinder, as long as it can provide horizontal driving force. At the same time, the actuating member 62 is installed at the position of the holding tube 11, and a rotary cap is installed at the right end of the holding tube 11 to facilitate opening to check the working state of the actuating member 62 in the holding tube 11, which is convenient for maintenance and repair;

[0049] Regarding the sampling member 3, it is used to take fecal samples deep into the intestine. Therefore, refer to Figure 7, the sampling piece 3 includes a through tube 31, and the through tube 31 is detachably installed at the free end of the mounting base 21. The disassembly and assembly method can adopt screw connection or snap connection. Based on the convenience of disassembly, at the same time, the through tube 31 penetrates through from left to right. There is a through diagnostic sample cavity 32 inside the through tube 31 for accommodating samples. Moreover, an inner folding edge 33 is provided at one end of the through tube 31 away from the mounting base 21 to increase the thickness of the end of the through tube 31 and avoid damaging the intestinal wall due to excessive sharpness. Moreover, a first baffle 34 and a second baffle 35 are arranged in a staggered manner at the inner folding edge 33. The first baffle 34 and the second baffle 35 are made of flexible rubber material and can be deformed by being squeezed by feces when pushed towards the feces direction, so that the hard feces can smoothly enter the diagnostic sample cavity 32, completing rapid sampling. Especially when taking fecal samples from sheep, its granular hard feces can more smoothly enter the sampling piece 3. At the same time, when the sampling piece 3 is withdrawn from the intestine, the first baffle 34 and the second baffle 35 block the opening of the through tube 31 to prevent the entered sample from falling back when being withdrawn from the intestine. The staggered arrangement can leave a large gap between the first baffle 34 and the second baffle 35 on the same layer, reducing the resistance of feces entering the through tube 31, and can also play a role of mutual sealing. When not affected by external forces, the first baffle 34 and the second baffle 35 cooperate to block the gap left on the same layer to prevent the liquid in the feces from easily flowing out of the through tube 31, facilitating the later extraction of the liquid contained in the feces for testing;

[0050] Regarding the sliding plate 8, to ensure the sampling depth, that is, because the sampling piece 3 adopts a passive sampling method of feces extrusion, although the structure of the sampling piece 3 is simplified and the sampling operation difficulty is reduced, however, this semi-open design has a risk that feces in the path will enter the sampling piece 3 first before the sampling piece 3 enters the deep intestine. Therefore, referring to Figure 8 and Figure 10 , the sliding plate 8 includes a net plate 81 arranged coaxially with the through tube 31. A check valve two 82 is installed at the center position of the net plate 81. A telescopic member 9 is connected to one end of the check valve two 82 facing the mounting base 21. The telescopic member 9 is connected to a gas source 4 through an air pipe 5. During the process of inserting into the intestine, the gas source 4 can use a miniature two-way air pump. The gas source 4 inflates the telescopic member 9 to make it extend, pressing the sliding plate 8 against the second baffle 35 so that it cannot bend, thus temporarily closing the inlet of the sampling piece 3 and blocking the feces on the insertion path from entering the sampling piece 3. After reaching the sampling position, the gas source 4 extracts the gas in the telescopic member 9, causing the telescopic member 9 to shorten, and the sliding plate 8 to disengage from the second baffle 35 so that it can be pressed and bent. At this time, the inlet of the sampling piece 3 can be aligned with the feces and pushed, so that the feces are squeezed into the sampling piece 3, realizing smooth deep sampling.

[0051] In a further embodiment, the specific configuration of the telescopic member 9 is disclosed. Referring to Figure 9, the telescopic member 9 includes an elastic member 92. The elastic member 92 adopts a spindle-shaped spring structure and is in a flat state with a short length when not under external force. Moreover, a sleeve 91 is sleeved outside the elastic member 92. The sleeve 91 is fixedly installed between the check valve II 82 and the air outlet end of the air pipe 5. Both ends of the elastic member 92 are fixedly installed with the check valve II 82 and the air pipe 5 respectively. Before the extension member 2 pushes the sampling member 3 to the sampling position, the air source 4 supplies air to the telescopic member 9. The check valve II 82 prevents the gas in the telescopic member 9 from flowing into the sampling member 3. The sleeve 91 is inflated and elongated to block the slide plate 8 at the deformation positions of the first baffle 34 and the second baffle 35, avoiding feces at non-lesion positions from entering the sampling member 3. After reaching the lesion position or the sampling depth, the air source 4 evacuates the telescopic member 9. The air in the sampling member 3 enters the sleeve 91 through the check valve II 82. The telescopic member 9 shortens driven by the rebound of the elastic member 92, causing the slide plate 8 to disengage from the first baffle 34 and the second baffle 35. The first baffle 34 and the second baffle 35 can swing towards the diagnostic sample cavity 32 of the sampling member 3 when squeezed by feces, enabling the fecal sample to enter the diagnostic sample cavity 32. Continuously evacuating the air in the sampling member 3 through the telescopic member 9 makes the sampling member 3 in a negative pressure state, which can also increase the sampling efficiency of thin and runny fecal samples.

[0052] In a further embodiment, to ensure the smooth progress of negative pressure sampling, refer to Figure 8 and Figure 9 , an outer ring 83 is fixedly installed on the circumferential outer wall of the net disk 81. A receiving cavity 25 is provided on the side of the mounting seat 21 facing the slide plate 8. The inner wall of the receiving cavity 25 is frustum-shaped, that is, the inner diameter of the receiving cavity 25 is the largest at the end facing the sampling member 3 and gradually decreases as it moves away from the sampling member 3. The outer diameter of the outer ring 83 is smaller than the inner diameter of the opening of the receiving cavity 25. The telescopic member 9 is coiled in the receiving cavity 25. In this way, after the telescopic member 9 is evacuated, the elastic member 92 that elongates and stores energy will rebound, coiling the telescopic member 9 in the receiving cavity 25. At the same time, the elastic force of the elastic member 92, combined with the guiding of the inner wall of the receiving cavity 25, will smoothly pull the slide plate 8 into the receiving cavity 25 and cooperate with the shielding of the net disk 81 to prevent fecal samples from entering the receiving cavity 25 and the check valve II 82, ensuring that the sleeve 91 will not be flattened by fecal samples and affecting gas passage, and also preventing the check valve II 82 from being blocked by feces, and the gas in the sampling member 3 can be continuously evacuated until the sampling member 3 is filled.

[0053] In a further embodiment, the specific configuration of the air source 4 is disclosed. Refer to Figure 3, the gas source 4 includes a handball 42 which has two gas passing ports installed with check valve I 43. By using the squeezable handball 42 in combination with check valve I 43, the handball 42 functions as a one-way gas pump. Specifically, when squeezing the handball 42, the gas inside the handball 42 is extruded from the gas passing port at the left end. When relaxed, the outside air enters the handball 42 from the gas passing port at the right end. During use, a hose 41 is detachably connected to one of the gas passing ports of the handball 42, and the hose 41 is cooperatively inserted into the intake end of the air pipe 5. When it is necessary to inflate the telescopic member 9, the outlet port of the handball 42 is connected to the intake end of the air pipe 5 through the hose 41 for continuous pressing inflation. Similarly, when it is necessary to evacuate the sampling member 3, the intake port of the handball 42 is connected to the intake end of the air pipe 5 through the hose 41 for continuous pressing exhaust, performing manual inflation and deflation operations. The inflation and deflation rate can be changed by pressing the handball 42, avoiding the inability to block the feces in the path due to the low output air pressure of the micro air pump. Similarly, it can also avoid the insufficient negative pressure of the sampling member 3 caused by the low air extraction power of the micro air pump, unable to complete the sampling work of runny feces. The hose 41 and the handball 42 can be designed to be transparent. When performing negative pressure suction sampling, the sampling progress can be judged by observing whether there are continuous bubbles entering the hose 41 and the handball 42. For example, if more fecal liquid enters and fewer bubbles, it means that the fecal sample has basically filled the sampling member 3. The detachable hose 41 and handball 42 can be disposable, ensuring the maintenance convenience of the equipment for repeated use.

[0054] In a further embodiment, to ensure the smooth change of the advancing direction of the sampling member 3, referring to Figure 3 and Figure 4 , both the pull rope 61 and the air pipe 5 are arranged in the middle through space of the equidistant spiral section 22 and the conical spiral section 23. The relay member 13 is respectively provided with through holes that cooperate with the pull rope 61 and the air pipe 5. The pull rope 61 for adjusting the advancing direction of the sampling member 3 is placed in the equidistant spiral section 22 and the conical spiral section 23. A skin 24 is sleeved and installed between the relay member 13 and the mounting seat 21 on the outside of the equidistant spiral section 22 and the conical spiral section 23, which can cooperate with the skin 24 to resist the extrusion of the outside on the pull rope 61, preventing the pull rope 61 from being squeezed together and affecting the independent pulling actions, ensuring that the pull rope 61 can still be smoothly pulled after the extension member 2 enters the livestock intestine, ensuring the flexible and stable operation.

[0055] In a further embodiment, referring to Figure 3 and Figure 5, disclose the specific configuration of the actuating member 62. There are four actuating members 62, and the four actuating members 62 are sequentially fixed on the inner circumferential wall of the holding cylinder 11 along the axial direction of the holding cylinder 11. The actuating members 62 are arranged in a staggered manner, and the staggered arrangement of the four actuating members 62 corresponds to the four fingers holding the holding cylinder 11. In this way, the slide 622 can be pressed by four fingers, and the wedge 626 is squeezed to pull the pull rope 61. Specifically, the actuating member 62 includes a limit frame 628. The limit frame 628 is fixed in the holding cylinder 11. A slide 622 is slidably installed in the limit frame 628 along the radial direction of the holding cylinder 11. A wedge 626 is slidably installed in the limit frame 628 along the axial direction of the holding cylinder 11. The wedge 626 is fixedly connected to the pull rope 61. The opposite sides of the slide 622 and the wedge 626 are respectively provided with a first inclined surface 625 and a second inclined surface 627. One end of the first inclined surface 625 and the second inclined surface 627 far from the pull rope 61 inclines towards the inner circumferential wall of the holding cylinder 11. When the finger presses the slide 622, the second inclined surface 627 can be squeezed through the first inclined surface 625, so that the wedge 626 is pulled away from the sampling member 3, and the equidistant spiral section 22 can be bent and deformed. When the slide 622 is relaxed, the equidistant spiral section 22 rebounds and resets, so that the wedge 626 can be reset, thereby realizing the control of the advancing direction of the sampling member 3, manually controlling and quickly penetrating into the sampling position. Compared with the electric control, the control precision and flexibility are higher, and the structure is simpler and more stable, and it is not easy to fail.

[0056] In a further embodiment, referring to Figure 3 and Figure 5 , to increase the operation convenience of the actuating member 62, a convex strip 621 is provided at one end of the slide 622 facing the inner circumferential wall of the holding cylinder 11. A contact piece 63 is embedded and installed at the position of the holding cylinder 11 corresponding to the convex strip 621. The convex strip 621 is provided at the end of the slide 622 pressed by the finger, so as to connect a contact piece 63 with a larger area. In this way, the slide 622 can be slid by pressing the contact piece 63, reducing the precision required for the operation of pressing the slide 622. The slide 622 is provided with a support strip 623 along the radial direction of the holding cylinder 11. The limit frame 628 is provided with a socket 629 corresponding to the positions of the slide 622 and the support strip 623. The sliding connection of the support strip 623 and the limit frame 628 along the radial direction of the holding cylinder 11 plays a role in limiting the slide 622, preventing the slide 622 from moving axially along the holding cylinder 11, resulting in the inability to press the slide 622 to squeeze the wedge 626 to slide axially along the holding cylinder 11, and further making the operation simpler by improving the structural stability.

[0057] In a further embodiment, for the convenience of different doctors to use, referring to Figure 6 and Figure 11, one end of the holding tube 11 connected to the relay member 13 is provided with a swivel joint 14. An annular sleeve 16 is sleeved and installed on the outer side of the swivel joint 14. The swivel joint 14 has a convex ring that fits with the annular groove of the annular sleeve 16, enabling the two to rotate relative to each other but not slide relative to each other axially, forming an actively constrained assembly. At the same time, a thumb rest 12 is fixed to the outer circumferential wall of the annular sleeve 16. The thumb rest 12 can be inserted with the thumb to assist in holding the holding tube 11. A sliding groove 17 corresponding to the position of the contact piece 63 is provided on the inner circumferential wall of the annular sleeve 16. The sliding groove 17 is a quarter-circular annular groove. Moreover, the starting end of the sliding groove 17 is located at the farthest position of the annular sleeve 16 from the thumb rest 12. The sliding groove 17 extends 90 degrees from the starting end towards the thumb rest 12 to form a terminating end. Among them, a limiting block 15 is fixedly installed at the starting end of the sliding groove 17 of the swivel joint 14. The limiting block 15 can slide in the sliding groove 17 when the annular sleeve 16 rotates relative to the swivel joint 14. Furthermore, a first convex key 18 and a second convex key 19 that cooperate with the limiting block 15 are respectively provided at the starting end and the terminating end of the sliding groove 17. The limiting block 15 can be locked when it slides to the starting end and the terminating end of the sliding groove 17. In this way, when a left-handed doctor uses it, the limiting block 15 can be stuck at the position of the first convex key 18. At this time, the thumb is sleeved in the thumb rest 12 to play a role in increasing the auxiliary holding point, and the other four fingers can lightly hold the holding tube 11. The distal phalanx corresponds to the upper edge position of the four contact pieces 63, so as to more conveniently grip and relax to control the four actuating members 62 through the four fingers. When a right-handed doctor uses it, the thumb rest 12 rotates 90 degrees relative to the holding tube 11, and the limiting block 15 can be stuck at the position of the second convex key 19. At this time, the lower edge position of the four contact pieces 63 is raised to the same height as the original upper edge position, that is, after the thumb extends to the thumb rest 12, the distal phalanx can still correspond to the raised lower edge position of the four contact pieces 63, which is also convenient for operating and controlling the four actuating members 62, and the practicability is stronger.

[0058] In a further embodiment, to improve the use stability of the commutator 6, refer to Figure 5 , an avoidance opening 624 is provided on the side of the carriage 622 facing the wedge block 626. Pressing the carriage 622 to move it towards the axis of the holding tube 11 will cause the carriage 622 to approach the pull rope 61. Therefore, to prevent the carriage 622 and the pull rope 61 from wearing each other, an avoidance opening 624 is provided at the position of the carriage 622 facing the pull rope 61. Among them, the avoidance opening 624 penetrates the carriage 622 along the axial direction of the holding tube 11, and the inner width of the avoidance opening 624 is greater than the outer diameter of the pull rope 61, so that the carriage 622 will not contact the pull rope 61 during the pressing and resetting processes, ensuring the stability during long-term use.

[0059] In a further embodiment, refer to Figure 4, an installation hole is formed in the mounting base 21, and a visual module 7 is installed in the installation hole. The visual module 7 can adopt a micro camera for endoscope, which can facilitate endoscope observation, so that the sampling piece 3 can extend to the lesion position more accurately for sampling, and can also observe the internal situation of the livestock intestine in real time, so as to control the sampling progress and prevent secondary damage caused by sampling. At the same time, the wire of the visual module 7 extends along the extension 2 to the position of the relay 13, and the plug of the visual module 7 is embedded on the circumferential outer wall of the relay 13, which is convenient to connect an external display device to display the internal situation of the intestine and facilitate accurate sampling operation.

[0060] The above is only the preferred embodiment of the present invention, and is not used to limit the protection scope of the present invention.
