Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to an ultrasonic positioning in-vivo sampling needle. Background Art

[0002] During the treatment of patients, it is often necessary to sample and detect the lesion site according to different conditions for medical analysis, so it is necessary to sample the sample or reagent. Currently, there are various sampling devices, and among them, the sampling needle sampling is relatively common. There are also many types of sampling needles, and different sampling methods are adopted according to the structural shapes of the sampling needles. One type of sampling needle head has a threaded structure. When in use, the entire sampling needle needs to be rotated into the lesion tissue, and then directly lifted and pulled out vertically. The sampled sample will remain between the threads of the sampling needle head; then the sample can be removed.

[0003] However, for this sampling method, due to the large trauma surface, and bleeding often occurs when directly lifting the sampling needle head upwards; currently, the bleeding condition that occurs after sampling cannot be quickly stopped; resulting in excessive bleeding from the trauma wound, which is not conducive to the control of the condition, and serious infections may occur. Moreover, when the simple sampling needle rotates into the sampling site, since it is impossible to identify whether the sampling needle head reaches the lesion site, sampling failure or poor sampling effect often occurs. And when the sampling needle rotates into the lesion site, the user's hand needs to move downwards as the sampling needle moves downwards, causing inconvenience to the user's operation.

[0004] Therefore, we urgently need a solution that is convenient for sampling and extracting the spiral sampling needle head and can quickly take measures for bleeding. In view of the above problems, we designed an ultrasonic positioning in-vivo sampling needle. Summary of the Invention

[0034] As Figures 1-13 shown, the object of the present invention is achieved as follows: An ultrasonic positioning in-vivo sampling needle includes a box body 2, and a cover plate 1 is detachably arranged on the front side of the box body 2, and the cover plate 1 and the box body 2 can be closed. A needle insertion port 5 is arranged on the right side of the bottom of the box body 2, the needle insertion port 5 is of a conical structure, and the depth of the needle insertion port 5 is the same as the distance that the guide block 22 can move up and down on the rotating cylinder 7. The right side of the needle insertion port 5 is open, facilitating the sampling needle 25 to move out to the right from the needle insertion port 5.

[0035] The needle insertion port 5 has a conical structure, which is convenient for observing the needle insertion site. At the same time, it can facilitate the accurate identification of the sampling site below the needle insertion port 5 by the ultrasonic probe 3. If the needle insertion port 5 is too large and wide, it is not easy for the ultrasonic probe 3 to identify that the needle insertion port 5 is exactly above the sampling site; the ultrasonic probe 3 is arranged on the left side of the needle insertion port 5, and the ultrasonic probe 3 can identify the positions of the sampling needle 25 and the hemostatic needle 27 at the sampling site and the position of the lesion site; a through hole one is opened on the right side of the box body 2, and the sampling syringe 6 can slide out to the through hole on the right side. After sliding out, the sampling syringe 6 can be taken out of the clamping plate 9 conveniently and quickly. The clamping plate 9 is slidably arranged in the box body 2, and two clamping grooves 35 are opened on the front side of the clamping plate 9, and the hemostatic syringe 8 and the sampling syringe 6 are respectively clamped in the clamping grooves 35.

[0036] The hemostatic syringe 8 is clamped on the left side of the clamping plate 9, and the sampling syringe 6 is clamped on the right side of the clamping plate 9. The sampling syringe 6 is located directly above the needle insertion port 5. A slider one 23 is slidably arranged in the sampling syringe 6. A sampling needle 25 is arranged in the sampling syringe 6. The upper part of the sampling needle 25 has a rectangular cross-section structure. There is a threaded connection between the middle part of the sampling needle 25 and the slider one 23. When the sampling needle 25 moves down, when the slider one 23 contacts the middle part of the sampling needle 25, there is a threaded connection between them. When clamped, the slider one 23 is at the lowest end of the through hole six 42, and the rectangular structure at the upper end of the sampling needle 25 is completely located in the rotating rod 4. When the rotating rod 4 moves down to the lowest position, it drives the threaded position in the middle of the sampling needle 25 to just be stuck above the slider one 23, and rotating the sampling needle 25 makes the two threaded connections. The upper part of the sampling syringe 6 is a rotating mechanism. The rotating mechanism includes a rotating cylinder 7. The rotating cylinder 7 is clamped with the sampling syringe 6. A slider two 21 is slidably arranged in the rotating cylinder 7. A rotating rod 4 is rotatably arranged in the slider two 21. A through hole five is opened on the upper right side of the box body 2, and the upper end of the rotating rod 4 is located in the through hole five, which is convenient for placing the sampling syringe 6.

[0037] A rectangular groove is opened on the lower end face of the rotating rod 4. The upper part of the sampling needle 25 is slidably located in the rectangular groove on the lower end face of the rotating rod 4; a hemostatic needle 27 is arranged in the hemostatic syringe 8. The hemostatic needle 27 is movably located in the hemostatic syringe 8. A balloon 31 is arranged at the lower end of the hemostatic needle 27. Medical absorbent cotton 26 is distributed on the outer side of the balloon 31. A liquid injection pipe 34, a water inlet pipe 33 and a water outlet pipe 32 are arranged in the hemostatic needle 27. The lower end of the liquid injection pipe 34 is connected with the medical absorbent cotton 26, and the lower ends of the water inlet pipe 33 and the water outlet pipe 32 are respectively connected with the balloon 31.

[0038] A plurality of guide blocks 22 are evenly arranged on the outer side surface of the second slider 21. Guide grooves that match the guide blocks 22 are evenly formed on the outer side surface of the rotating cylinder 7. The guide blocks 22 are located in the guide grooves and can slide up and down. The distance that the guide blocks 22 can move up and down in the guide grooves is the same as the distance from the lower end of the needle insertion port 5 to the inner bottom surface of the box body 2. A first shifting rod 24 is connected to the outer side surface of the first slider 23. A first sliding groove is formed on the outer side surface of the sampling syringe 6. The first sliding groove is of an L-shaped structure. The first shifting rod 24 is located in the first sliding groove. The L-shaped structure can prevent the first slider 23 from moving upward when the sampling needle 25 rotates in threaded connection with the first slider 23. A clamping mechanism can be arranged at the bottom of the transverse hole at the lower end of the first sliding groove to clamp the first shifting rod 24 at the bottom of the first sliding groove without rotating the shifting rod.

[0039] A push handle 19 is arranged on the rear side surface of the clamping plate 9. A fourth through hole 18 is transversely formed at the rear side of the box body 2. The push handle 19 is located in the fourth through hole 18 and can slide left and right. When the push handle 19 moves to the rightmost end, the hemostatic syringe 8 is located directly above the needle insertion port 5. A second sliding groove 20 is formed on the upper side surface of the hemostatic syringe 8. A third slider 29 is arranged at the upper end of the hemostatic needle 27. The third slider 29 is located in the hemostatic syringe 8 and can slide up and down. A second shifting rod 30 is fixedly arranged on the outer side surface of the third slider 29. The second shifting rod 30 is located in the second sliding groove 20 and can slide up and down. A third through hole 17 is formed at the rear side of the box body 2. The third through hole 17 is of an L-shaped structure. The second shifting rod 30 can slide in the third through hole 17.

[0040] A first pressure rod 40 is arranged through the second shifting rod 30. A retaining ring 38 is fixedly arranged on the outer side surface of the first pressure rod 40. A first spring 39 is sleeved on the outer side surface of the first pressure rod 40. The first pressure rod 40 can slide through the third slider 29. A card slot is formed in the third slider 29. A card 36 is rotatably arranged in the card slot. A rotating rod 4 is rotatably arranged in the upper middle part of the card 36. Both ends of the rotating rod 4 are fixedly connected to the card slot. A card tooth 41 is fixedly arranged on the outer side surface of the lower end of the card 36. The end of the first pressure rod 40 contacts the upper end of the card 36. A second spring 37 is connected to the rear side of the lower end of the card 36. The end of the second spring 37 is connected to the rear end of the card slot. A row of card slots 35 are longitudinally and evenly formed on the inner side surface of the front side of the hemostatic syringe 8. A second through hole 16 is formed on the left side of the box body 2. The upper end of the second through hole 16 penetrates through the front side surface of the box body 2. A sixth through hole 42 is formed in the upper part of the side wall of the hemostatic syringe 8. A seventh through hole 28 is formed at the upper end of the hemostatic needle 27. The upper ends of the water inlet pipe 33, the water outlet pipe 32, and the liquid injection pipe 34 sequentially pass through the seventh through hole 28, the sixth through hole 42, and the second through hole 16.

[0041] The ultrasonic probe 3 is rotatably located at the lower part of the box body 2. The ultrasonic probe 3 is connected to the box body 2 through a rotating shaft 10. The rotating shaft 10 is fixedly connected to the ultrasonic probe 3 and rotatably connected to the box body 2. The outer end of the rotating shaft 10 is fixedly connected with a rotating plate 11. The upper end of the rotating plate 11 is rotatably connected with a locking rod 13. The upper end of the locking rod 13 is rotatably connected to the upper end of the rotating plate 11. The front part of the lower end of the locking rod 13 is fixedly connected with a handle 12. The middle part of the rear side of the locking rod 13 is rotatably connected with a locking pin 15. A locking pin groove 14 is opened on the box body 2 at the rear side of the locking pin 15. The handle 12 and the locking rod 13 are openable and closable within the rotating plate 11, which can reduce the occupied space of the mechanism and is more convenient to use. A circular locking pin 15 is provided. The locking pin 15 can not only ensure the locking of the rotating plate 11, making the rotating plate 11 unable to rotate, but also take out the locking pin 15 and hold the locking pin 15 to rotate the locking rod 13, which can make it more convenient to rotate the rotating plate 11. The outer end of the rotating shaft 10 is rotatably connected with a rotating plate 11. When the rotating plate 11 and the rotating shaft 10 can rotate relative to each other, different rotation methods can be applied, so that the rotating plate 11 can be separated from the side of the box body 2 for convenient rotation.

[0042] When in use, the lower end of the sampling needle 25 is placed in the slider 23 in the sampling syringe 6, and the lower part of the sampling needle 25 is connected to the slider 23 for sliding up and down connection. The upper end of the sampling needle 25 is placed in the lower end of the rotating rod 4, and the lower end of the sampling needle 25 is flush with the lower end surface of the sampling syringe 6. Then, the sampling syringe 6 is clamped and fixed with the rotating cylinder 7, and the sampling syringe 6 is clamped into the right side of the clamping plate 9, and the hemostatic syringe 8 is clamped into the left side of the clamping plate 9, and then placed together with the clamping plate 9 in the box body 2. At this time, the push handle 19 on the rear side of the clamping plate 9 is located in the through hole four 18, and the lower end surfaces of the sampling syringe 6 and the hemostatic syringe 8 are in contact with the inner bottom surface of the box body 2, and the upper end of the rotating cylinder 7 is in contact with the inner upper surface of the box body 2; the upper ends of the water outlet pipe 32, the water inlet pipe 33, and the injection pipe 34 are placed in the through hole two 16; the lever two 30 is located in the through hole three 17, and the sampling needle 25 is located directly above the needle inlet 5. The box body 2 is covered with a cover plate 1, and the ultrasonic probe 3 is placed near the sampling position required. The ultrasonic probe 3 is positioned to align the needle insertion port 5 just above the sampling position required, and the guide block 22 of the rotating rod 4 is pressed down to move downward along the guide groove to the bottom of the guide groove. At this time, the sampling needle 25 moves downward to the bottom of the needle insertion port 5, that is, it fits the skin, and the rotating rod 4 is rotated. The rotating rod 4 drives the sampling needle 25 to rotate. When the sampling needle 25 rotates, since the slider 23 and the sampling needle 25 are threadedly connected, the sampling needle 25 moves downward and penetrates the skin. The upper end of the sampling needle 25 slowly moves downward along the rectangular groove of the rotating rod 4, and the rotating rod 4 continues to be rotated until the needle head of the sampling needle 25 reaches the sampling position, and the rotating rod 4 is stopped. Since the head of the sampling needle 25 is a threaded structure, it needs to be rotated to enter the sampling position. The needle head of the sampling needle 25 clamps the sample into the threaded position, and then it is lifted vertically upward to take out the sample. That is, turn the lever 1 24 so that it is located in the vertical hole of the through hole 6 42, push the lever 1 24 upward, and the lever 1 24 drives the sampling needle 25 to move upward through the slider 1 23. Push upward until it can no longer be pushed upward. At this time, the rectangular structure at the upper end of the sampling needle 25 is completely stuck in the rectangular groove at the lower end of the rotating rod 4. At the same time, the sampling needle 25 moves upward against the rotating rod 4 until the guide block 22 on the outer side of the slider 21 moves to the upper end of the guide groove. At this time, the lower end surface of the sampling needle 25 is completely located in the sampling syringe 6. Push the push handle 19 to the right and push the push handle 19 to the rightmost end of the through hole 4 18. At this time, the hemostatic syringe 8 is just above the needle inlet 5. When bleeding is found after the sampling needle 25 is pulled out, the hemostatic needle 27 can be used quickly to stop bleeding without finding the wound surface. The lever 2 30 of the hemostatic syringe 8 is located above the vertical hole on the rightmost side of the through hole 3 17. The sampling syringe 6 is completely pushed out from the right side of the housing 2, and the sampling syringe 6 and the rotating cylinder 7 can be taken forward, and then the sampling syringe 6 and the rotating cylinder 7 are disassembled, and the sampling needle 25 is taken out, so that sampling of the sampling part can be achieved.

[0043] When a large amount of bleeding is found after the sampling needle 25 is withdrawn, the first pressure rod 40 above the second lever 30 can be directly pressed. The front end of the first pressure rod 40 presses against the card 36, causing the card 36 to rotate around the rotating rod 4. The engaging teeth 41 at the lower end of the card 36 disengage from the card slot 35 on the hemostatic syringe 8. Moving the first pressure rod 40 downward can drive the hemostatic needle 27 to move downward. At this time, the hemostatic needle 27 moves downward along the needle insertion port 5 to the wound. The hemostatic needle 27 enters the wound. By observing through the ultrasonic probe 3 the depth at which the lower end of the hemostatic needle 27 enters the wound, when the predetermined depth is reached, the first pressure rod 40 is released. Under the action of the elastic force of the first spring 39, the first pressure rod 40 is pushed outwards. At this time, under the action of the elastic force of the second spring 37, the card 36 presses against the lower end of the card 36 and moves outwards, and the engaging teeth 41 are snapped into the card slot 35. Thereby restricting the up and down movement of the hemostatic needle 27 in the hemostatic syringe 8. Cold water is supplied into the balloon 31 at the lower end of the hemostatic needle 27 through the water inlet pipe 33, and the water in the balloon 31 is discharged through the water outlet pipe 32. Controlling the flow rate of the water supply can change the pressure in the balloon 31, and thereby control the degree of expansion of the balloon 31. The greater the water pressure in the balloon 31, the greater the balloon 31 expands, and thereby the medical absorbent cotton 26 outside the balloon 31 is pushed up to fill the wound and squeeze the blood vessels at the wound to stop bleeding. At the same time, the cold water in the balloon 31 can reduce the temperature of the wound, which is beneficial to hemostasis; Hemostatic agents are injected into the medical absorbent cotton 26 through the liquid injection pipe 34, so that the wound is contaminated with hemostatic agents, which is beneficial to hemostasis.

[0044] Since the human body parts and the diseased parts are diverse, when it comes to special sampling parts, the needle insertion angle of the sampling needle 25 needs to be changed, but the angles of the ultrasonic probe 3 and the needle insertion port 5 need to be adjusted. This device can turn over the locking lever 13 by holding the handle 12, so that the locking lever 13 rotates around the upper end of the rotating plate 11, and the locking pin 15 is taken out of the locking pin slot 14 to release the rotation restriction of the rotating plate 11 relative to the box body 2. Holding the locking lever 13, the rotating plate 11 can be rotated, so that the rotating plate 11 rotates around the rotating shaft 10, thereby driving the ultrasonic probe 3 to rotate and changing the direction of the ultrasonic probe 3.
