Description

Balloon lead capable of being positioned in real time and control method thereof

Technical Field

The invention relates to the technical field of medical instruments, in particular to a balloon lead capable of being positioned in real time and a control method thereof.

Background

The balloon catheter is a soft catheter with an inflatable balloon at the top end, and is long and thin, and the rigidity, namely the pushing property, is poor, so when the balloon catheter is used, the balloon catheter is usually matched with an endoscope to work together, is inserted into a channel of the endoscope, is guided to reach a focus position through observation and positioning of the endoscope, and is pushed out of the endoscope at the moment, then is inflated, and is anchored in a lumen, and then is withdrawn. After the aim of surgery is fulfilled, the balloon is deflated and the catheter is removed, and the safe, rapid and accurate establishment of the channel and fixation can be realized, so that the balloon catheter is widely applied.

However, since the size of the endoscope is generally large, and particularly when performing a broncho-surgical procedure, the human bronchi (class 1) to alveoli branch to about 24 levels, and because of the outer diameter limitation of the bronchoscope, the endoscope cannot reach a finer bronchus, and thus a normal procedure is to continue pushing the balloon catheter out of the endoscope after the balloon catheter has been delivered to a position where it can be reached by the endoscope, it can enter a finer bronchus because of the small size of the balloon catheter. However, the balloon catheter does not have an observation and positioning function, and after the balloon catheter is separated from the endoscope, the balloon catheter cannot be ensured to enter the focus position, and even if the balloon is fixed at the focus position, the position of the balloon is not displayed, and the excision position is not easy to determine during operation, so that the operation may fail.

For this reason, two balloon catheter designs are emerging on the market: attached wires or quick-change. The balloon catheter with the guide wire is structurally characterized in that a channel is arranged in the balloon catheter, a guide wire penetrates out of the channel, and the guide wire is visible under X-ray image equipment, so that positioning and guiding of the balloon position are realized. However, in this way, on one hand, the balloon catheter needs to extend a longer distance beyond the balloon at its distal end to guide the guide wire, so that the balloon cannot be directly anchored at the lesion, and a distance remains between the balloon and the lesion; on the other hand, the position of the guide wire cannot be fixed, and the guide wire cannot stay in the body along with the balloon catheter, so that positioning cannot be provided in the subsequent postoperative process. Aiming at the balloon catheter capable of being rapidly replaced, the two ends in the balloon are provided with developing rings, and the developing rings can be positioned by utilizing ultrasonic development or X-ray image equipment. Such a structure needs to be used with ultrasound equipment or imaging systems and cannot be positioned in real time.

For the pathological changes of bronchi, the bronchectomy uses wedge cutting, segment cutting or leaf cutting according to the size of the focus range, and although the wedge cutting and cutting have fewer cutting parts, the recurrence rate of the cutting mode may be higher, so that segment cutting is mostly adopted at present. For section cutting, the position of a section opening needs to be positioned, a balloon wire in the prior art generally anchors a balloon at a focus position, and as a certain distance exists between the focus position on a bronchus and the section opening, the distance is different for different bronchi and different patients, so that the position of the section opening cannot be positioned accurately.

In summary, the prior art has the following drawbacks, in a first aspect: the balloon of the balloon catheter cannot be positioned in real time, so that the balloon catheter is not sure whether the balloon catheter reaches the focus position or not when being pushed. Further, for operation of the lung, when the balloon catheter is pushed, the lung is in a filling state, and during operation, the lung is collapsed, the space position of the balloon is changed, and under the condition that the balloon is not positioned, the focus position of balloon positioning cannot be directly found.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific examples, which are not intended to be limiting, so that those skilled in the art will better understand the invention and practice it. In the invention, one end close to an operator is a near end, and the other end far away from the operator is a far end.

When the lung is full, the position relation between the focus and the corresponding segment mouth can be determined according to a three-dimensional map of the lung drawn by a pre-operation lung CT (computed tomography) and the like, however, when an operation is performed, the lung is in a collapsed state, an original three-dimensional bronchial tree collapses, and all bronchi are stacked, so that a three-dimensional map image of the lung, which is originally constructed in a CT and the like mode, is invalid, and the focus position can not be positioned any more. By anchoring the magnetic sensor 3 at the focus, the position of the balloon lead can be displayed in real time through the display device even if the lung collapses and the three-dimensional map cannot be used.

The present invention provides a balloon lead positioned in real time, as shown with reference to fig. 1, comprising: a first tube body 1, a first balloon 2 and a magnetic sensor 3; the far end of the first tube body 1 is fixed with a first saccule 2; the end part of the first pipe body 1 provided with the first saccule 2 is simultaneously provided with a magnetic sensor 3; the magnetic sensor 3 is glued to the first tube 1 by means of UV glue.

A first ventilation channel 101 and a magnetic sensor connecting wire 102 are arranged in the first tube body 1; the first ventilation channel 101 communicates with the first balloon 2; the proximal end of the first ventilation channel 101 is provided with a sealing valve 103; the magnetic sensor 3 is connected to the display device via a magnetic sensor connection line 102.

The first tube body 1 is inserted into the endoscope and enters the focus position along with the endoscope, at the moment, the first balloon 2 is inflated through the sealing valve 103 of the first ventilation channel 101, so that the first balloon 2 is fixed at the focus position, and the magnetic sensor 3 near the first balloon 2 is connected with the display device for real-time positioning. In the operation process, even though the spatial position of the focus changes after the lung collapses, the first balloon 2 is always fixed at the focus position, so the relative position of the magnetic sensor 3 and the focus is unchanged, and the magnetic sensor 3 can be sensed in real time, so that the focus can be positioned in real time.

Specifically, in this embodiment, the first tube body 1 is formed by extrusion, and has a diameter of 1.9mm, and can pass through the 2.0 channel of the endoscope. In other embodiments of the invention, the first tubular body 1 may also be shaped in other ways. The diameter of the first tube 1 may be any value smaller than the different endoscope channels.

The far end of the first tube body 1 is fixedly provided with a first balloon 2, the magnetic sensor 3 is fixed at the first balloon 2 and has a distance smaller than 0.5cm from the first balloon 2, the first balloon 2 is fixed in a focus after being inflated, the magnetic sensor 3 is simultaneously fixed, the position is accurate, and the movement is not easy to occur; the magnetic sensor 3 on the first tube body can not be shifted to cause inaccurate positioning when the first balloon 2 is inflated, the smaller the distance is, the more accurate the positioning is, and the more accurate the focus excision treatment can be caused in the operation process.

In this embodiment, referring to fig. 2, a first connector 4 is fixedly connected to the proximal end of the first tube 1; a first channel 401 is arranged on one side of the inside of the first connecting piece 4, wherein the first channel 401 corresponds to the first ventilation channel 101, when the first balloon 2 needs to be inflated, the needle 9 is inserted into the first channel 401, and then the gas is filled into the first ventilation channel 101 after passing through the sealing valve 103. The first connector 4 is internally provided with a second channel 402 and a third channel 403. The two magnetic sensor connecting wires 102 of the magnetic sensor 3 are respectively penetrated out of the second channel 402 and the third channel 403 after being separated and fixed in the second channel 402 and the third channel 403, and the penetrated magnetic sensor connecting wires 102 can be directly connected with a display device provided with jacks.

Before the operation, the first tube body 1 is inserted into the endoscope and enters the focus position along with the endoscope, at this time, the first balloon 2 is fixed at the focus position by using the needle 9 to pass through the first channel 401 and to inflate the first balloon 2 through the sealing valve 103 of the first ventilation channel 101, and two magnetic sensor connecting wires of the magnetic sensor 3 are directly connected with a display device provided with a matched socket after passing out from the second channel 402 and the third channel 403 for real-time positioning. In the operation process, even though the spatial position of the focus changes after the lung collapses, the first balloon 2 is always fixed at the focus position, so the relative position of the magnetic sensor 3 and the focus is unchanged, and the magnetic sensor 3 can be sensed in real time, so that the focus can be positioned in real time.

In this embodiment, the three channels of the first connector 4 are of the same diameter and can be directly matched during installation without the need to align specifically which channel to thread.

In this embodiment, the proximal end of the first connector 4 is detachably connected to the second connector 5; two contacts 501 are arranged inside the second connecting piece 5 corresponding to the second channel 402 and the third channel 403; before the operation, the first tube body 1 is inserted into the endoscope and enters the focus position along with the endoscope, at this time, the first balloon 2 is inflated by using the needle 9 to pass through the first channel 401 and pass through the sealing valve 103 of the first ventilation channel 101, so that the first balloon 2 is fixed at the focus position, two magnetic sensor connecting wires of the magnetic sensor 3 pass through the second channel 402 and the third channel 403 and then contact with two contacts 501 of the second connecting piece 5, at this time, a connecting wire is led out by the display device, and the end part of the connecting wire is connected with the second connecting piece 5 to position the magnetic sensor 3 in real time.

In the present embodiment, the second connecting member 5 is provided with a fourth passage 502; the fourth channel 502 communicates with the first channel 401.

When the first balloon 2 needs to be inflated, the needle 9 can be directly inserted into the fourth channel 502 and then passes through the first channel 401 without detaching the first connecting piece 4 from the second connecting piece 5, and then the air is inflated into the first ventilation channel 101 after passing through the sealing valve 103, so that the operation time of an operation is saved.

In this embodiment, the proximal end of the second connector 5 is provided with a positioning wire plug 6 that is matched with the second connector 5, and the positioning wire plug 6 is used for inserting the second connector 5 into some display devices having different sockets, so that the magnetic sensor 3 can be adapted to various different display devices, and the operation cost is saved.

Example two

In the prior art, if the balloon lead is directly anchored at the position of the segment opening, the focus is inconvenient to observe accurately, and if the balloon lead is anchored at the position of the focus, the positioning of the segment opening is inaccurate due to the uncertainty between the segment opening and the focus. In this embodiment, a double balloon is provided, and as shown in fig. 3, the method specifically includes: a first tube body 1, a first balloon 2, a magnetic sensor 3, a second tube body 7 and a second balloon 8; the far end of the first tube body 1 is fixed with a first saccule 2; the end part of the first pipe body 1 provided with the first saccule 2 is simultaneously provided with a magnetic sensor 3; the first pipe body 1 is sleeved with a second pipe body 7; the distal end of the second tube body 7 is provided with a second saccule 8; a second ventilation channel 701 is arranged in the second pipe body 7; the second ventilation channel 701 is communicated with the second balloon 8 through a second ventilation hole 801, and the diameter of the second ventilation channel 701 is 0.25-0.3mm. The surface of the second tube 7 is provided with graduation marks 702.

In this embodiment, the second tube 7 may be sleeved outside the first tube 1 before insertion into the lung, with both the distal and proximal ends of the first tube 1 extending beyond the second tube 7. The sleeved tube body is inserted into an endoscope (the diameter of the tube body is increased due to the existence of the second tube body 7, and therefore, the endoscope with the aperture larger than 2.0mm is needed to be inserted), the endoscope guides the tube body to reach the position where the endoscope can reach, the tube body is further pushed in, the first tube body 1 reaches the focus position, and the endoscope can be withdrawn at the moment because the positions of the first balloon 2 and the magnetic sensor 3 are basically overlapped, the first balloon 2 is inflated, and the first balloon 2 is directly anchored at the focus. Because the lung is in a filling state at this time, the position relationship between the focus and the corresponding segment can be determined according to a three-dimensional map of the lung drawn by the preoperative lung CT and the like, so that the position of the second tube 7 can be adjusted according to the scale marks 702 on the second tube 7.

In this embodiment, after the magnetic sensor is anchored at the focus by the first balloon 2, the second tube 7 may be sleeved outside the first tube 1, so that the second tube 7 moves along the first tube 1 until the second tube 7 reaches the segment corresponding to the focus according to the scales on the first tube 1 and the second tube 7, and the second balloon 8 is inflated and anchored at the segment.

In this embodiment, the length of the second tube 7 is smaller than that of the first tube 1, so as to control the second tube 7 to move on the first tube 1.

Example IV

A balloon wire control method capable of being positioned in real time for operating a balloon wire control system capable of being positioned in real time comprises the following steps:

s4001, inserting a first tube body into a channel of an endoscope, pushing the endoscope out of the narrow bronchus after the endoscope enters the bronchus with larger diameter;

in this embodiment, the endoscope brings the first tube 1 to the bronchi with a larger diameter, and the endoscope cannot go deep further because of the larger size of the endoscope, at this time, the first tube 1 is pushed out of the endoscope, and the first tube 1 can enter the bronchioli with a narrower diameter because of the smaller diameter.

S4002, connecting a magnetic sensor connecting wire of a magnetic sensor with display equipment, and displaying the real-time position of a balloon wire;

in this embodiment, the magnetic sensor connection line 102 may be directly connected to the display device; the magnetic sensor connection line 102 may also be connected to the display device via the first connection piece 4; the magnetic sensor connecting wire 102 can also be connected with the display device through the first connecting piece 4 inserted with the second connecting piece 5; the magnetic sensor connecting wire 102 can also be connected with the display device through the first connecting piece 4, the second connecting piece 5 and the positioning wire plug 6.

S4003, after the first saccule reaches the focus, the needle head is inserted into a sealing valve at the proximal end of the first ventilation channel to inflate the first saccule;

in this embodiment, after the first balloon 2 reaches the lesion, it can be determined whether the first balloon 2 has been anchored by pulling the first tube 1.

In this embodiment, when the magnetic sensor connection wire 102 is directly connected to the display device, the needle 9 is inserted into the sealing valve 102 at the proximal end of the first ventilation channel 101 to inflate the first balloon 2; when the magnetic sensor connecting wire 102 is connected with the display device through the first connecting piece 4, the needle 9 passes through the first channel 401 and inflates the first balloon 2 through the sealing valve 103 of the first ventilation channel 101, and when the first tube body 1 is pulled at this time, the first tube body 1 is still electrically connected with the display device, so that whether the position of the first balloon 2 changes can be intuitively observed; when the magnetic sensor connecting wire 102 is connected with the display device through the first connecting piece 4 and the second connecting piece 5 or through the first connecting piece 4 and the second connecting piece 5 and then the positioning wire plug 6, the first connecting piece 4 and the second connecting piece 5 can be detached first and then the needle 9 passes through the first channel 401 and the first balloon 2 is inflated through the sealing valve 103 of the first ventilation channel 101; the needle 9 can be inserted into the fourth channel 502 and then pass through the first channel 401 and inflate the first balloon 2 through the sealing valve 103 of the first ventilation channel 101, and when the first tube 1 is pulled at this time, since the first tube 1 is still electrically connected with the display device, whether the position of the first balloon 2 changes can be intuitively observed.

S4004, after the first saccule is anchored, the needle is withdrawn, and the endoscope is removed from the bronchus;

in this embodiment, if the first connector 4 and the second connector 5 are separated, the endoscope is directly moved out, and if the first connector 4 and the second connector 5 are not separated, the first connector 4 and the second connector 5 are separated and then moved out of the endoscope;

s4005, if the second air bag is required to be anchored at the segment opening, the second pipe body is sleeved outside the first pipe body, so that the second pipe body moves along the first pipe body until the second pipe body reaches the segment opening corresponding to the focus according to the scales on the first pipe body and the second pipe body, and the second air bag is inflated and anchored at the segment opening.

In this embodiment, the second tube 7 may be sleeved outside the first tube 1 before insertion into the lung, and both the distal end and the proximal end of the first tube 1 extend out of the second tube 7. The sleeved tube body is inserted into an endoscope (the diameter of the tube body is increased due to the existence of the second tube body 7, and therefore, the endoscope with the aperture larger than 2.0mm is needed to be inserted), the endoscope guides the tube body to reach the position where the endoscope can reach, the tube body is further pushed in, the first tube body 1 reaches the focus position, and the endoscope can be withdrawn at the moment because the positions of the first balloon 2 and the magnetic sensor 3 are basically overlapped, the first balloon 2 is inflated, and the first balloon 2 is directly anchored at the focus. Because the lung is in a filling state at this time, the position relationship between the focus and the corresponding segment opening can be determined according to a lung three-dimensional map drawn by the preoperative lung CT and the like, so that the position of the second tube body 7 can be adjusted according to the scale marks 702 on the first tube body 1 and the second tube body 7, the second balloon 8 is positioned at the segment opening, and the second balloon 8 is inflated to be anchored at the segment opening.

As the procedure progresses, the air-filled lung tissue becomes a closed state in which the alveoli collapse due to air loss. Because of collapse of the lung, the bronchial tree which is originally in a three-dimensional form collapses, and all bronchi are stacked, so that a lung three-dimensional map image which is originally constructed in a CT (computed tomography) mode and the like fails, the focus position can not be positioned any more, and at the moment, the position of the focus in the collapsed lung can be displayed in real time according to the magnetic sensor 3 on the first tube body 1.

It is apparent that the above examples are given by way of illustration only and are not limiting of the embodiments. Other variations and modifications of the present invention will be apparent to those of ordinary skill in the art in light of the foregoing description. It is not necessary here nor is it exhaustive of all embodiments. And obvious variations or modifications thereof are contemplated as falling within the scope of the present invention.
