Description

Technical Field

[0001] The present invention belongs to the technical field of biopsy puncture, and specifically relates to a novel biopsy puncture needle track occluder. Background Technique

[0002] Biopsy, short for "biological tissue examination", refers to taking a living tissue sample or cell sample from a patient's body through surgery, such as cutting, clamping, or puncturing, for pathological examination by a pathologist; biopsy and pathological examination are usually to deeply understand whether a lesion / mass is cancer, the type of cancer, and the nature of the cancer, etc., so as to guide the patient's subsequent overall treatment plan, including surgery, radiotherapy, and drug treatment.

[0003] Currently, the occlusion of the puncture needle track mainly achieves hemostasis by inserting gelatin sponge to block the bleeding point. Specifically, a vascular sheath needs to be inserted into the puncture needle track, then the vascular sheath is removed using an exchange guide wire, and then a dilatation sheath is inserted along the exchange guide wire until the front end of the dilatation sheath reaches the bleeding point. Then, the exchange guide wire and the dilatation sheath are removed, and finally, the gelatin sponge is inserted along the dilatation sheath. The actual operation is relatively complex, requiring the cooperation of multiple instruments, with a high operation difficulty and low efficiency, and a high professional requirement for the operator. Otherwise, there are relatively large safety hazards.

[0004] For example, for the puncture needle track occluder disclosed in CN202235535U, first, the guide wire is pre-inserted into the body to the affected area, then the outer sheath is sleeved on the guide wire, and the occluding material is pushed along the guide wire to the tapered opening at the front end of the outer sheath inside the outer sheath; then, the above-mentioned outer sheath, occluding material, and push tube are jointly pushed to the appropriate part in the body to be occluded, and the metal positioning object plays a positioning role; then, the occluding material is pushed out from the tapered opening of the outer sheath into the puncture needle track to be occluded, and the occluding material expands rapidly and occludes in the puncture needle track to be occluded; finally, except for the occluding material, the rest are pulled out of the body to complete the occlusion operation of the puncture needle track. Although to a certain extent, it makes it easier and more accurate to push the occluding material to the occluding part, the overall operation is still relatively complex.

[0005] Therefore, it is necessary to develop a novel puncture needle track occluder to reduce the actual operation difficulty. Summary of the Invention

[0006] To solve the problems raised in the above background technique, the present invention provides a novel biopsy puncture needle track occluder, which has the advantages of easy operation and high efficiency.

[0007] Among them, with the cooperation of a regulating mechanism and the like, the plugging tube and the plugging plug can move relative to each other simultaneously. Furthermore, while facilitating the stable removal of the entire plugging sleeve, the plugging plug slowly moves downward relative to the plugging tube, thereby achieving the effect of placing gelatin sponge while removing the puncture plugging device. This not only reduces the operation difficulty and improves the operation efficiency, but also can promote the good placement of the gelatin sponge into the puncture needle track, avoiding the situation where local accumulation fails to completely cover the bleeding point.

[0008] To achieve the above object, the present invention provides the following technical solution: a novel biopsy puncture needle track plugging device, including a plugging sleeve and a positioning piece. The positioning piece is movably sleeved outside the plugging sleeve. A puncture sampling needle is movably inserted through the inside of the plugging sleeve. The top of the positioning piece is connected with a telescopic component. The upper end of the telescopic component is fixedly connected to the upper end of the plugging sleeve. The top of the plugging sleeve is fixedly connected with a regulating mechanism, and the regulating mechanism communicates with the plugging sleeve;

[0009] The plugging sleeve includes a plugging tube hermetically sleeved inside the positioning piece. The lower end of the inner cavity of the plugging tube is fixedly sleeved with a positioning sleeve. A plugging plug located above the positioning sleeve is hermetically sleeved inside the plugging tube. A protective cavity is opened at the lower end of the middle part of the plugging plug; The inner wall of the lower end of the inner cavity of the plugging tube is filled with gelatin sponge, and the upper end of the inner cavity of the plugging tube communicates with the regulating mechanism.

The upper end of the communicating hose communicates with the upper end of the inner cavity of the plugging tube through the regulating mechanism.

[0011] Preferably, the puncture sampling needle includes a limiting plug hermetically sleeved inside the plugging tube. A puncture sampling needle is fixedly sleeved in the middle of the limiting plug. A first through hole located outside the puncture sampling needle is opened inside the limiting plug. Both the upper and lower ends of the first through hole communicate with the inside of the plugging tube.

[0012] Preferably, the limiting plug is located above the plugging plug. The lower end of the puncture sampling needle sequentially penetrates through the limiting plug, the plugging plug and the positioning sleeve and extends below the plugging tube. The outer diameter of the puncture sampling needle is smaller than the inner diameter of the protective cavity. The upper end of the puncture sampling needle sequentially penetrates through the limiting plug and the plugging tube and extends above the regulating mechanism and is fixedly connected with an operating head.

[0013] Preferably, the telescopic component includes a communicating ring fixedly connected to the top of the positioning piece. The top of the communicating ring is fixedly connected with a folding telescopic tube. The upper end of the folding telescopic tube is fixedly connected with a connecting ring. The connecting ring is fixedly sleeved on the upper end of the plugging tube.

[0014] Preferably, the control assembly includes a piston cylinder fixedly installed inside the communication ring. One end of the piston cylinder extends into the communication ring and is connected to an air outlet valve. One end of the air outlet valve communicates with the inside of the piston cylinder, and the other end of the air outlet valve communicates with the sealed space between the telescopic assembly and the plugging pipe. An intake valve is also provided inside the piston cylinder. One end of the intake valve communicates with the inside of the piston cylinder, and the other end of the intake valve communicates with the external space of the piston cylinder. When the spring piston rod inside the piston cylinder is reciprocally pulled, the intake valve sucks in external air and pushes it into the space between the telescopic assembly and the plugging pipe through the piston cylinder and the air outlet valve.

[0015] Preferably, the regulation mechanism includes a sealing head threadedly sleeved on the upper end of the plugging pipe. The top of the sealing head extends above the plugging pipe and is fixedly connected to a communication assembly. The lower end of the sealing head is hermetically fitted with a sealing ring. The sealing ring is fixedly sleeved inside the plugging pipe. A pushing piston is further provided at the lower end of the sealing ring. The pushing piston is hermetically sleeved between the plugging pipe and the puncture sampling needle.

[0016] Preferably, the communication assembly includes an adjustment knob fixedly connected to the top of the sealing head. A limit communication groove located outside the puncture sampling needle is formed at the top of the adjustment knob. A plurality of uniformly distributed communication grooves are formed at the bottom of the adjustment knob and inside the sealing head. The upper end of the communication groove communicates with the limit communication groove, and the lower end of the communication groove communicates with the space above the pushing piston inside the plugging pipe.

[0017] Preferably, a positioning communication ring is hermetically sleeved inside the limit communication groove.

The lower end of the communication hose is fixedly connected to the top of a connection ring and communicates with the sealed space between the communication ring, the connection ring, the folding telescopic pipe, and the plugging pipe.

[0018] Preferably, a second through hole that communicates with each other is formed inside the positioning communication ring and the adjustment communication ring. The lower end of the second through hole is fixedly communicated with the communication hose, and the lower end of the second through hole communicates with the second through hole. The distance dimension between two adjacent communication grooves is smaller than the inner diameter dimension of the second through hole.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. Due to the setting of the telescopic component, with the cooperation of the regulation mechanism and others, the plugging tube and the plugging stopper can move relative to each other simultaneously. Thus, while facilitating the stable removal of the overall plugging sleeve, the plugging stopper can move downward slowly relative to the plugging tube, achieving the effect of discharging the gelatin sponge while removing the puncture plugging device. This not only reduces the operation difficulty and improves the operation efficiency but also can promote the good placement of the gelatin sponge into the puncture needle track, avoiding the situation where it accumulates locally and cannot completely cover the bleeding point.

[0021] 2. Due to the setting of the folding telescopic tube, with the cooperation of the connecting ring and the coupling ring, the folding telescopic tube can be continuously extended through the control component, enabling the plugging tube to move upward slowly relative to the positioning piece, thus achieving the effect of facilitating the stable removal of the overall plugging sleeve.

[0022] 3. Due to the setting of the limiting plug, the puncture sampling needle can move downward following the pushing piston, that is, avoiding the situation where the lower end of the puncture sampling needle and the sample inside it move relative to the plugging stopper. Furthermore, it ensures that the sample can always be protected inside the protection cavity, avoiding the contact between the plugging stopper and the gelatin sponge at its bottom and the sample.

[0023] 4. Due to the setting of the regulation mechanism, the flow efficiency of air entering the inside of the plugging tube can be changed. When the plugging tube completely disengages from the puncture needle track, the moving range of the plugging stopper is changed, thus achieving the effect of controlling the dosage of the gelatin sponge.

Specific embodiments

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] As Figures 1 to 7 shown, the present invention provides a new biopsy puncture needle track plugging device, including a plugging sleeve 1 and a positioning piece 2. The positioning piece 2 is movably sleeved outside the plugging sleeve 1. A puncture sampling needle 3 is movably inserted through the inside of the plugging sleeve 1. The top of the positioning piece 2 is connected with a telescopic assembly 4, and the upper end of the telescopic assembly 4 is fixedly connected to the upper end of the plugging sleeve 1. The top of the plugging sleeve 1 is fixedly connected with a regulation mechanism 5, and the regulation mechanism 5 is in communication with the plugging sleeve 1;

[0034] The plugging sleeve 1 includes a plugging tube 11 hermetically sleeved inside the positioning piece 2. The lower end of the inner cavity of the plugging tube 11 is fixedly sleeved with a positioning sleeve 12. The inside of the plugging tube 11 is hermetically sleeved with a plugging stopper 13 above the positioning sleeve 12. A protection cavity 14 is opened at the lower end of the middle of the plugging stopper 13. The inner wall of the lower end of the inner cavity of the plugging tube 11 is filled with gelatin sponge, and the upper end of the inner cavity of the plugging tube 11 is in communication with the regulation mechanism 5. Due to the setting of the telescopic assembly 4, with the cooperation of the regulation mechanism 5 and others, the plugging tube 11 and the plugging stopper 13 can move relatively at the same time, so as to conveniently and stably take out the whole plugging sleeve 1, and at the same time, the plugging stopper 13 moves slowly downward relative to the plugging tube 11, so as to achieve the effect of putting the gelatin sponge while taking out the puncture plugging device. This not only reduces the operation difficulty and improves the operation efficiency, but also can promote the gelatin sponge to be well put into the puncture needle track, avoiding the situation that it cannot completely cover the bleeding point due to local accumulation.

[0035] As Figure 1As shown in the figure, there are two control components 6 on the left and right at the lower end of the telescopic component 4. A communication hose 7 is also connected to the top of the telescopic component 4. The lower end of the communication hose 7 is communicated with the inside of the telescopic component 4, and the upper end of the communication hose 7 is communicated with the upper end of the inner cavity of the plugging tube 11 through the regulation mechanism 5.

[0036] As Figure 3 and Figure 6 shown in the figure, the puncture sampling needle 3 includes a limit plug 33 hermetically sleeved inside the plugging tube 11. A puncture sampling needle 32 is fixedly sleeved in the middle of the limit plug 33. A first through hole 34 is opened inside the limit plug 33 on the outside of the puncture sampling needle 32. Both the upper and lower ends of the first through hole 34 are communicated with the inside of the plugging tube 11. Due to the setting of the limit plug 33, the puncture sampling needle 32 can move downwards following the pushing piston 54, that is, to avoid the situation where the lower end of the puncture sampling needle 32 and the sample inside it move relative to the plugging plug 13, and further ensure that the sample can always be protected inside the protection cavity 14, and avoid the situation where the plugging plug 13 and the gelatin sponge at its bottom come into contact with the sample.

[0037] As Figure 3 and Figure 6 shown in the figure, the limit plug 33 is located above the plugging plug 13. The lower end of the puncture sampling needle 32 sequentially penetrates through the limit plug 33, the plugging plug 13 and the positioning sleeve 12 and extends below the plugging tube 11. The outer diameter of the puncture sampling needle 32 is smaller than the inner diameter of the protection cavity 14. The upper end of the puncture sampling needle 32 sequentially penetrates through the limit plug 33 and the plugging tube 11 and extends above the regulation mechanism 5 and is fixedly connected with an operating head 31. Due to the setting of the regulation mechanism 5, the flow efficiency of air entering the inside of the plugging tube 11 can be changed, so that when the plugging tube 11 completely disengages from the puncture needle track, the moving range of the plugging plug 13 is changed, so as to achieve the effect of controlling the dosage of the gelatin sponge.

[0038] As Figure 3 and Figure 4 shown in the figure, the telescopic component 4 includes a communication ring 41 fixedly connected to the top of the positioning piece 2. A folding telescopic tube 43 is fixedly connected to the top of the communication ring 41. The upper end of the folding telescopic tube 43 is fixedly connected with a connection ring 42. The connection ring 42 is fixedly sleeved on the upper end of the plugging tube 11. Due to the setting of the folding telescopic tube 43, with the cooperation of the communication ring 41 and the connection ring 42, the folding telescopic tube 43 can be continuously extended through the control component 6, so that the plugging tube 11 can move upwards slowly relative to the positioning piece 2, so as to achieve the effect of conveniently and stably taking out the whole plugging sleeve 1.

[0039] As Figure 4As shown in the figure, the control component 6 includes a piston cylinder 61 fixedly installed inside the connecting ring 41. One end of the piston cylinder 61 extends into the inside of the connecting ring 41 and is connected with an air outlet valve 62. One end of the air outlet valve 62 is communicated with the inside of the piston cylinder 61, and the other end of the air outlet valve 62 is communicated with the sealed space between the telescopic component 4 and the plugging tube 11. An air inlet valve 63 is also arranged inside the piston cylinder 61; one end of the air inlet valve 63 is communicated with the inside of the piston cylinder 61, and the other end of the air inlet valve 63 is communicated with the external space of the piston cylinder 61. When the spring piston rod inside the piston cylinder 61 is reciprocally pulled, the air inlet valve 63 sucks in external air and pushes it into the space between the telescopic component 4 and the plugging tube 11 through the piston cylinder 61 and the air outlet valve 62; due to the arrangement of the air outlet valve 62 and the air inlet valve 63, when the piston cylinder 61 reciprocates, external air can be continuously pressed into the inside of the telescopic component 4, thereby causing the telescopic component 4 to expand and elongate. At the same time, with the cooperation of the connecting component 51, part of the gas slowly enters the plugging tube 11, so that while the plugging tube 11 is separated from the puncture needle track, it can be ensured that the plug 13 can push out the gelatin sponge along the inside of the plugging tube 11.

[0040] As Figure 4 shown in the figure, the regulation mechanism 5 includes a packaging head 52 threadedly sleeved on the upper end of the plugging tube 11. The top of the packaging head 52 extends above the plugging tube 11 and is fixedly connected with a connecting component 51. The lower end of the packaging head 52 is hermetically fitted with a sealing ring 53. The sealing ring 53 is fixedly sleeved inside the plugging tube 11. A pushing piston 54 is also arranged at the lower end of the sealing ring 53. The pushing piston 54 is hermetically sleeved between the plugging tube 11 and the puncture sampling needle 32.

[0041] As Figure 5 shown in the figure, the connecting component 51 includes an adjusting knob 511 fixedly connected to the top of the packaging head 52. A limiting connecting groove 512 located outside the puncture sampling needle 32 is opened at the top of the adjusting knob 511. A number of uniformly distributed connecting grooves 515 are opened at the bottom of the adjusting knob 511 and inside the packaging head 52. The upper end of the connecting groove 515 is communicated with the limiting connecting groove 512, and the lower end of the connecting groove 515 is communicated with the space at the top of the pushing piston 54 inside the plugging tube 11.

[0042] As Figure 5 shown in the figure, a positioning connecting ring 513 is hermetically sleeved inside the limiting connecting groove 512. An adjusting connecting ring 514 is rotatably clamped at the top of the positioning connecting ring 513. The outer surface of the adjusting connecting ring 514 is hermetically sleeved inside the positioning connecting ring 513. The top of the adjusting connecting ring 514 is fixedly connected to the upper end of the connecting hose 7. The lower end of the connecting hose 7 is fixedly connected to the top of the connecting ring 42 and is communicated with the sealed space between the connecting ring 41, the connecting ring 42, the folding telescopic tube 43 and the plugging tube 11.

[0043] AsFigure 4 and Figure 5 As shown in Figure 5 , a second through hole 516 that communicates with each other is provided inside the positioning connecting ring 513 and the adjusting connecting ring 514. The lower end of the second through hole 516 is fixedly communicated with the connecting hose 7, and the lower end of the second through hole 516 communicates with the second through hole 516; the distance dimension between two adjacent connecting grooves 515 is smaller than the inner diameter dimension of the second through hole 516.

[0044] The working principle and usage process of the present invention:

[0045] After assembling the device as shown in the figure, the whole plugging sleeve 1 is inserted into the puncture needle track, then the positioning piece 2 is pressed tightly on the patient's skin surface, and then the operating head 31 is manipulated to drive the puncture sampling needle 32 at its lower end to move to complete puncture sampling;

[0046] After the puncture sampling is completed, the operating head 31 is lifted upward until the limit plug 33 on the surface of the operating head 31 rises to the bottom of the pushing piston 54. At this time, the lower end of the operating head 31 and the sample inside it are in the protection cavity 14, effectively avoiding contact with the gelatin sponge on the inner wall of the plugging tube 11;

[0047] Then, while pressing the positioning piece 2 with the palm, the thumb and index finger repeatedly press the left and right piston cylinders 61, so that external air can enter the folding telescopic tube 43 under the cooperation of the air outlet valve 62 and the air inlet valve 63. At the same time, part of the gas enters the top area of the pushing piston 54 in the plugging tube 11 through the connecting hose 7 and the regulating mechanism 5;

[0048] When the gas enters the folding telescopic tube 43, the folding telescopic tube 43 can expand and elongate. Then, under the limitation of the positioning piece 2 and through the cooperation of the connecting ring 41 and the connecting ring 42, the upper end of the plugging tube 11 slowly moves upward along the inside of the positioning piece 2, so that the whole plugging sleeve 1 and the puncture sampling needle 3 are taken out of the puncture needle track at the same time;

[0049] The air that enters the top of the pushing piston 54 in the plugging tube 11 through the connecting hose 7 can press down the pushing piston 54 and drive the puncture sampling needle 3 and the whole to slowly move downward along the inside of the plugging tube 11. Then, under the cooperation of the sealing environment in the plugging tube 11, the pushing piston 54 pushes the plugging block 13 through the air at its bottom, and the downward movement of the plugging block 13 can push the gelatin sponge at the bottom of the plugging block 13 in the plugging tube 11 out through the positioning sleeve 12. The gelatin sponge that enters the puncture needle track expands when it meets blood, and can block the bleeding point;

[0050] Before the above operation, adjusting the control mechanism 5 can change the gas flow rate in the control mechanism 5 during the elongation of the folding telescopic tube 43, so that the movement range of the plug 13 in the plugging tube 11 changes when the entire plugging sleeve 1 completely disengages from the puncture needle track, thereby achieving the effect of controlling the amount of gelatin sponge used to ensure a good plugging effect and at the same time reducing the amount of gelatin sponge remaining in the patient's body;

[0051] That is, before the operation, rotate the adjusting connection ring 514 or the positioning connection ring 513 so that the second through holes 516 inside them move relative to each other, and the flow efficiency of the second through holes 516 can be changed.
