[0001] The invention relates to the technical field of tumor sampling, in particular to a gynecological tumor sampling instrument. Background Art
[0002] Tumor refers to a new organism formed by the proliferation of local tissue cells under the action of various tumorigenic factors. When treating patients with tumors, it is necessary to sample tumor cells first. When sampling tumor cells, a tumor cell sampling device is needed. However, the existing gynecological tumor sampler generally does not disinfect the tumor before sampling it through the sampling tube, so it is easy to cause infection. At the same time, after sampling the tumor, it needs to be transported to a special device to check the pathological condition of the tumor sample, so as to treat the patient more targeted. It takes a while to place the tumor cell sample in a special device for detection after sampling, and because the living environment of the tumor cells is different after sampling, the tumor sample will be necrotic. However, the existing gynecological tumor sampler does not culture the tumor sample, so it is easy to cause necrosis of the tumor tissue after sampling, which is not conducive to detection and processing after sampling, and increases the difficulty of sampling to a certain extent.

[0014] Beneficial effects of the present invention:
[0015] 1: By fixing sterile gauze on the side wall of the cylinder, when the sampled tumor moves inside the sampling cylinder, the body fluid attached to the tumor will be absorbed due to the action of the sterile gauze.
[0016] 2: A soft loading bag is fixedly connected to the side wall of the shell, and a disinfectant is filled in the soft loading bag, so that the sampling tube can be disinfected before the sampling tube samples the tumor.

[0017] 3: By filling the liquid box with culture fluid, it is convenient to flow the culture fluid in the liquid box into the loading plate. When the sampling tube is in an inclined state, the tumor in the sampling tube enters the upper surface of the loading plate in the loading box through the feed hole. Due to the gravity of the tumor, the loading plate will move downward. In the process of the loading plate moving downward, the first blocking rod moves downward. Since the first blocking rod is fixedly connected to the connecting column, the connecting column moves downward during the downward movement of the first blocking rod, so that the connecting column is located in the liquid inlet hole. Since the area value of the cross section of the connecting column is smaller than the aperture of the liquid inlet hole, the culture fluid in the liquid box flows to the upper surface of the loading plate through the liquid inlet hole, so as to cultivate the tumor on the upper surface of the loading plate. As more and more culture fluid accumulates on the upper surface of the loading plate, the loading plate continues to move downward due to gravity. In the process of the loading plate moving downward, the second blocking rod moves downward. When the second blocking rod is located in the liquid inlet hole, the liquid inlet hole is blocked by the second blocking rod, so that the culture fluid in the loading box is prevented from flowing into the upper surface of the loading plate.
[0018] The present invention realizes the disinfection of the sampling tube before sampling the tumor through the sampling tube, and the tumor is placed on the carrier plate for culture after sampling. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.
[0028] like Figure 1-Figure 6 As shown, a gynecological tumor sampling instrument of the present invention comprises a sampling tube 1, a sampling hook 2 is provided on the side wall of the sampling tube 1, and a shell 3;
[0029] Both ends of the sampling tube 1 are fixedly connected with a fixing rod 4, one end of the fixing rod 4 passes through the shell 3 and is fixedly connected with a rotating disk 5, the left and right sides of the outer side of the shell 3 are elastically connected with a moving plate 6, and the moving plate 6 is fixedly connected with a locking rod 7, and the outer side walls of the rotating disk 5 and the shell 3 are provided with locking holes 8, and the locking holes 8 cooperate with the locking rod 7;
[0030] A soft charging bag 9 is fixedly connected to the inner side wall of the shell 3, and a first blocking block 10 is threadedly connected to the opening of the soft charging bag 9. A connecting rod 11 is fixedly connected to the movable plate 6, and one end of the connecting rod 11 passes through the side wall of the shell 3 and is fixedly connected to an extrusion plate 12, and the extrusion plate 12 cooperates with the soft charging bag 9. A fixing ring 13 is fixedly connected to the circumferential outer side wall of the sampling tube 1, and a cavity 14 is opened on the inner side wall of the fixing ring 13. The cavity 14 is connected to the soft charging bag 9 through a soft tube 15, and liquid outlet holes 16 are opened on the side walls of the cavity 14 and the sampling tube 1;
[0031] A support plate 17 is fixedly connected to the inner wall of the sampling tube 1 , the upper surface of the support plate 17 contacts a cylinder 18 , and a sterile gauze 19 is fixedly connected to the side wall of the cylinder 18 .
[0032] The movable plate 6 is elastically connected to the outer side wall of the housing 3 .
[0033] A charging barrel 21 is fixedly connected to the housing 3 , a first plate 22 and a second plate 23 are fixedly connected to the moving plate 6 , and a first hole 24 and a second hole 25 are respectively formed in the first plate 22 and the second plate 23 .
[0034] A loading box 26 is fixedly connected to the inner wall of the shell 3, and a feed hole 27 is opened on the top surface of the loading box 26. A baffle 28 is fixedly connected to the movable plate 6, and an inlet hole 29 is opened on the baffle 28. When it is necessary to place the tumor sampled in the sampling tube 1 in the loading box 26, the staff pushes the movable plate 6 to realize the movement of the baffle 28 through the movable plate 6. During the movement of the baffle 28, when the inlet hole 29 corresponds to the feed hole 27 and the upper port of the sampling tube 1 is located above the feed hole 27, it is convenient for the tumor in the sampling tube 1 to be poured into the loading box 26 through the inlet hole 29 and the feed hole 27.
[0035] The top of the charging box 26 is fixedly connected to a liquid box 30, and corresponding positions of the liquid box 30 and the charging box 26 are provided with a liquid inlet hole 31, and the opening at the top of the liquid box 30 is threadedly connected to a second blocking block 32, and a loading plate 33 is elastically connected to the charging box 26, and a first blocking rod 34 is fixedly connected to the loading plate 33, and a connecting column 35 is fixedly connected to the first blocking rod 34, and a second blocking rod 36 is fixedly connected to the connecting column 35. When it is necessary to add culture fluid to the charging box 26, the staff manually rotates the second blocking block 32, and when the second blocking block 32 is removed from the liquid box 30 ... When leaving, the staff pours the culture fluid into the liquid box 30 for storage, and then places the second blocking block 32 at the opening of the liquid box 30, and rotates the second blocking block 32 in the opposite direction to install the second blocking block 32 at the opening of the loading box 30, thereby pouring the culture fluid into the liquid box 30 for storage. When the tumor is placed on the upper surface of the carrier plate 33, the gravity of the tumor will move the carrier plate 33 downward, thereby moving the first blocking rod 34 downward, and the culture fluid in the liquid box 30 flows to the upper surface of the carrier plate 33 through the liquid inlet hole 31.
[0036] When the sampling tube 1 samples tumor cells, the sampling hook 2 is used to cut and sample the tumor cells, so that the sampled tumor sample is located inside the sampling tube 1. Then, the sampling tube 1 is rotated to make the top end of the sampling tube 1 correspond to the feed hole 27 of the loading box 26, so that when the tumor in the sampling tube 1 passes through the feed hole 27 and enters the upper surface of the loading plate 33 in the loading box 26, the gravity of the tumor will cause the loading plate 33 to move downward. In the process of the loading plate 33 moving downward, the first blocking rod 34 moves downward. Since the first blocking rod 34 is fixedly connected to the connecting column 35, the connecting column 35 moves downward in the process of the first blocking rod 34 moving downward. The connected column 35 is located in the liquid inlet hole 31. Since the area of the cross section of the connected column 35 is smaller than the aperture of the liquid inlet hole 31, the culture fluid in the liquid loading box 30 flows through the liquid inlet hole 31 to the upper surface of the carrier plate 33, thereby culturing the tumor on the upper surface of the carrier plate 33. As more and more culture fluid accumulates on the upper surface of the carrier plate 33, the carrier plate 33 continues to move downward due to gravity. During the downward movement of the carrier plate 33, the second blocking rod 36 moves downward. When the second blocking rod 36 is located in the liquid inlet hole 31, the liquid inlet hole 31 is blocked by the second blocking rod 36, thereby preventing the culture fluid in the loading box 26 from flowing into the upper surface of the carrier plate 33.
[0037] A second spring 37 is fixedly connected to the inner wall of the charging box 26 , and the upper end of the second spring 37 is fixedly connected to the carrier plate 33 . The second spring 37 is arranged to elastically connect the carrier plate 33 to the charging box 26 .
[0038] A first spring 20 is fixedly connected to the moving plate 6 , and one end of the first spring 20 is fixedly connected to the outer wall of the housing 3 .
[0039] Working principle: the staff manually pushes the movable plate 6 outward to realize the movement of the first plate 22. When the first hole 24 on the first plate 22 corresponds to the charging barrel 21, the second hole 25 of the second plate 25 is located on the outside of the charging barrel 21, and one end of the second plate 25 is located inside the lower part of the charging barrel 21, that is, one end of the second plate 25 realizes the blocking of the bottom of the charging barrel 21. The staff places the cylinder 18 in the charging barrel 21 for storage and standby use. Since one end of the second plate 25 is located inside the charging barrel 21 at this time, the bottom of the cylinder 18 is located on the upper surface of the second plate 25 during this process, and the cylinder 18 is supported by the second plate 25, that is, the cylinder 18 cannot move downward in the charging barrel 21. At the same time, since the second plate 23 is located below the charging barrel 21, the cylinder 18 placed in the charging barrel 21 is blocked to prevent the cylinder 18 from continuing to move downward in the charging barrel 21.
[0040] Then, the movable plate 6 is manually released, and the first plate 22 is moved due to the elastic force of the first spring 20, so that the first hole 24 of the first plate 22 is located outside the charging barrel 21, and the middle part of the first plate 22 passes through the charging barrel 21, that is, the middle part of the first plate 22 blocks the top of the charging barrel 21. In this process, the second plate 23 also moves accordingly. At that time, in this process, the second hole 25 of the second plate 23 is still located outside the charging barrel 21, and one end of the second plate 23 is located inside the charging barrel 21, that is, one end of the second plate 25 realizes the blocking of the bottom of the charging barrel 21. Therefore, in this process, the bottom of the cylinder 18 is still located on the upper surface of the second plate 25, and the cylinder 18 is supported by the second plate 25, that is, the cylinder 18 cannot move downward in the charging barrel 21 (such as Figure 1 shown).
[0041] The staff manually pushes the movable plate 6 outward, and the squeezing plate 12 squeezes the soft filling bag 9 through the connecting rod 11, so that the disinfectant in the soft filling bag 9 flows into the cavity 14 through the soft tube 15, and the disinfectant in the cavity 14 flows to the inner wall of the sampling tube 1 through the side liquid outlet 16, and the inner wall of the sampling tube 1 is disinfected, and the disinfectant in the cavity 14 flows to the outer wall of the sampling tube 1 through the lower liquid outlet 16, and the outer wall of the sampling tube 1 is disinfected.
[0042] When it is necessary to disinfect the inner and outer walls of the sampling tube 1, the staff manually loosens the movable plate 6. Due to the elastic force of the first spring 20, the movable plate 6 is reset, and the squeezing plate 12 is driven to reset through the connecting rod 11, that is, the squeezing plate 12 does not squeeze the soft loading bag 9, so the disinfectant contained in the soft loading bag 9 will not enter the cavity 14 through the soft tube 15, that is, there is no disinfectant in the cavity 14, so that the disinfectant in the cavity 14 will not flow out from the liquid outlet 16.
[0043] When it is necessary to sample the tumor through the sampling tube 1, the sampling tube 1 is in a vertical state (such as Figure 1 status shown).
[0044] After that, the staff pushes the movable plate 6 toward one side of the shell 3 to move the movable plate 6. In the process of the movable plate 6 moving inward, the second plate 23 moves. When the second hole 25 of the second plate 23 corresponds to the charging barrel 21, it is convenient for the cylinder 18 in the charging barrel 21 to fall into the sampling barrel 1. The sampling barrel 1 is located above the charging barrel 21, and there is no connection between the sampling barrel 1 and the charging barrel 21. Since the sterile gauze 19 is fixedly connected to the inner wall of the cylinder 18, Since the sterile gauze 19 is a soft material, the sterile gauze 19 has no fixed shape and is easy to wrinkle. Therefore, the sterile gauze 19 is fixedly connected to the inner wall of the cylinder 18, mainly to constrain the shape of the sterile gauze 19, so that the sterile gauze 19 is evenly fixed on the inner wall of the cylinder 18 to prevent the sterile gauze 19 from wrinkling when placed in the sampling cylinder 1; the cylinder 18 is dropped from the loading cylinder 21 into the sampling cylinder 1, and when the sampling cylinder 1 is already filled with sterile gauze 18 , it is convenient to store the spare sterile gauze 19 in the charging barrel 21. When the sampling barrel 1 is in a tilted state, the sterile gauze 18 that has been used in the sampling barrel 1 can be taken out. Then, the sampling barrel 1 is adjusted to a working state (that is, the sampling barrel 1 is in a vertical state), and the moving plate 6 is manually pushed. When the second hole 25 of the second plate 23 is located inside the charging barrel 21, that is, the second plate 23 does not block the bottom of the charging barrel 21, the spare sterile gauze 19 in the charging barrel 21 can be quickly dropped. into the sampling tube 1, thereby achieving the purpose of quickly placing the sterile gauze 19 in the sampling tube 1 and keeping the sterile gauze 19 in reserve; since the inner wall of the sampling tube 1 is fixedly connected to the support plate 17, when the cylinder 18 is placed in the sampling tube 1, the cylinder 18 is supported by the support plate 17, that is, the cylinder 18 will not continue to fall in the sampling tube 1, that is, the cylinder 18 is located above the sampling hook 2, so the cylinder will not block the sampling hook 2, that is, the cylinder 18 will not hinder the tumor from entering the sampling tube 1.
[0045] The staff holds the device and places the sampling tube 1 at the tumor in the body where sampling is required, and the sampling hook 2 interacts with the tumor in the body to achieve the purpose of sampling the tumor in the body, so that the tumor after sampling is located inside the sampling tube 1.
[0046] Afterwards, the movable plate 6 is manually released, and the movable plate 6 is moved outward due to the elastic force of the first spring 20. During the process of the movable plate 6 moving outward, the locking rod 7 is disengaged from the locking hole 8 of the turntable 5. Since the fixing rod 4 is rotatably connected to the shell 3, and the fixing rod 4 is fixedly connected to the sampling tube 1, the sampling tube 1 is manually rotated to rotate about the fixing rod 4. Before the upper end of the sampling tube 1 rotates to the feeding hole 27 of the charging box 26, the movable plate 6 is manually pushed outward to drive the baffle 28 to move through the movable plate 6. During the movement of the baffle 28, when the inlet hole 29 corresponds to the feeding hole 27, the upper end of the sampling tube 1 is located above the feeding hole 27, which facilitates the tumor in the sampling tube 1 to pass through the inlet hole 29 and the feeding hole 27 is poured into the loading box 26. If the tumor sample is cultured manually, since the culture device is not located near the sampling tube 1, after the tumor is sampled by the sampling tube 1, the tumor sample needs to be transported to the culture device by the transport device. Since the transportation process takes a certain amount of time, and the device for transporting the tumor is attached with bacteria in the air, it is easy to cause necrosis of the tumor sample during the transportation of the tumor sample by the transport device. The present application directly cultures the tumor sample after sampling the tumor sample by the sampling tube 1, so it does not take up the time for transporting the tumor sample. At the same time, the present application cancels the transportation of the tumor sample by the transport device, that is, there is no infection of the tumor sample by the transport device.
[0047] When the sampled tumor moves inside the sampling tube 1, the body fluid attached to the tumor will be sucked away due to the action of the sterile gauze 19.
[0048] When the sampling tube 1 is in an inclined state, when the tumor in the sampling tube 1 passes through the feed hole 27 and enters the upper surface of the carrier plate 33 in the loading box 26, the gravity of the tumor will cause the carrier plate 33 to move downward, and the first blocking rod 34 will move downward during the downward movement of the carrier plate 33. Since the first blocking rod 34 is fixedly connected to the connecting column 35, the connecting column 35 will move downward during the downward movement of the first blocking rod 34, so that the connecting column 35 is located in the liquid inlet hole 31. Since the cross-sectional area of the connecting column 35 is smaller than that of the liquid inlet hole 31, the connecting column 35 is located in the liquid inlet hole 31. The pore size is large, that is, the culture fluid in the liquid loading box 30 flows to the upper surface of the carrier plate 33 through the liquid inlet hole 31, so as to cultivate the tumor on the upper surface of the carrier plate 33. As more and more culture fluid accumulates on the upper surface of the carrier plate 33, the carrier plate 33 continues to move downward due to gravity. During the downward movement of the carrier plate 33, the second blocking rod 36 moves downward. When the second blocking rod 36 is located in the liquid inlet hole 31, the liquid inlet hole 31 is blocked by the second blocking rod 36, that is, the culture fluid in the loading box 26 is prevented from flowing into the upper surface of the carrier plate 33.
