Description

Visual Urinary Tract Aspirator

technical field

The invention relates to the field of medical devices, and furthermore, relates to a visual urinary tract lumen suction device.

Background technique

A ureteroscope is a medical device used for minimally invasive diagnosis and treatment in urology. A conventional ureteroscope consists of an optical fiber, a working lumen and various working accessories for different purposes. Ureteroscopic surgery is a slender ureteroscope that enters a 0.2 to 0.5 cm diameter ureter through the urethra, bladder, and ureteral orifice. After connecting the monitoring equipment, the lesions in the ureter or renal pelvis can be clearly observed, so as to pass through the working cavity. Diagnosis or treatment of ureteral diseases with different instruments inserted inside.

There are two main types of ureteroscopes in use today: rigid scope and flexible scope. Rigid scope, that is, ordinary ureteroscope, is used to treat diseases such as ureteral calculi. Because its main body is relatively hard and cannot be bent, it is suitable for the treatment of ureteral calculi. That is to say, it is suitable for the treatment of relatively straight or linear parts, while the flexible endoscope can be used to treat some stones in the upper ureter, as well as stones in the renal pelvis and calyx that cannot be treated by ordinary ureteroscopy.

Although flexible ureteroscopy can greatly complement the insufficiency of ordinary ureteroscopy and can be used to treat more tortuous paths or positional diseases that ordinary ureteroscopy cannot treat, there are still many unfavorable factors in practical applications.

The existing flexible ureteroscopes all need to work with the scope sheath. On the one hand, the scope sheath can provide an entry channel for the flexible scope, so that the flexible scope can enter the body smoothly. Annular gap, when the stone is sucked out, the gravel and debris are discharged through this gap. But there are many problems based on this working process.

First, the waste is sent out from the gap between the scope sheath and the flexible scope. Since the flexible ureteroscope needs to be operated in the relatively small space of the human ureter, its size is very small. In such a small size The base is long, and the size of the gap formed between the soft mirror and the mirror sheath is narrower, so it is very difficult to send out waste.

Secondly, the space between the flexible scope and the scope sheath is narrow. After the flexible scope enters the scope sheath, the shape of the remaining space in the scope sheath is irregular, which is only convenient for the discharge of liquid and sediment-like stones. It is easy to freeze the soft mirror and damage the soft mirror.

Third, since the crushed stone load needs to be discharged from the gap between the soft mirror and the mirror sheath, the size of the crushed stone is required to be very small. For example, the crushed stone needs to be powdered, which consumes a lot of crushed stone energy, and in the process of powdering In the process, due to the doping of stones of different sizes, the stone crushing efficiency is low, and repeated stone crushing is required, thus further causing energy loss.

Therefore, there is a great need for an appliance to solve the problem of gravel discharge.

The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art.

For example, but not limited to, the camera device 30 is integrated into the attracting body 10 . In other embodiments, the camera device 30 may also be detachably disposed on the attracting body 10. The camera device 30 may also be a camera with an integrated light source.

In an embodiment of the present invention, the camera device 30 is fixed to the suction end 11 of the suction body 10, and the end face of the camera device 30 is the same as the end face of the suction body 10, that is, The surface of the camera device 30 does not protrude from the outer surface of the attracting end 11 of the attracting body 10 . Preferably, the camera device 30 is embedded in the attracting end 11 of the attracting body 10 . In another embodiment of the present invention, the camera device 30 is movably connected to the attracting body 10 .

3A, 3B, the suction main body 10 has a suction channel 130, and the suction channel 130 is used for expelling debris in the body, such as, but not limited to, crushed stones, waste water, tumors, and the like. For example, when the visual urinary tract lumen suction device 100 is used to treat calculus disease, the broken stone and waste water in the body are discharged together through the suction channel 130 .

The suction channel 130 integrally extends between the suction end 11 of the suction main body 10 and the connection end, and the suction channel 130 communicates with the handle 20 .

Referring to FIG. 6 , the suction channel 130 is formed by a suction inner surface 1303, and the suction inner surface 1303 extends uniformly and integrally, that is, the suction inner surface 1303 is flat without seams or protrusions. uneven position, so as to facilitate the discharge of debris. Preferably, the suction channel 130 is a tubular channel. It is worth mentioning that the drainage channel of the traditional sheathed soft mirror is formed by the gap between the sheath and the soft mirror, that is to say, the channel contains the soft mirror, so the effective size for discharging gravel is very small. , so that larger stones cannot be discharged. In the embodiment of the present invention, most of the space inside the suction body 10 is the suction channel 130, and the size of the suction channel of the suction body 10 is greatly increased compared to the original suction slot, so in the early stage After the stone is crushed, the visual urinary tract lumen suction device 100 can be used to smoothly discharge the crushed stone or the larger-sized crushed stone.

In the technical solution of the present invention, the suction channel 130 is a hollow structure inside, and there are no other components inside, so the entire internal space is an effective discharge space, thereby greatly improving the discharge efficiency of sundries and wastes.

The suction channel 130 has a suction inlet 1301 and a suction outlet 1302, the suction inlet 1301 communicates with the handle 20, and the suction outlet 1302 is located at the suction end 11 of the suction body 10, that is, The position of the suction outlet 1302 is close to the outer end of the camera device 30, so that it is convenient to visually discharge the sundries and wastes, and suction and discharge can be carried out in a targeted manner.

Further, referring to FIGS. 3A and 3B , the camera device 30 of the auxiliary channel is located on one side to form a first working area 111 , and the suction channel 130 is located on the other side to form a second working area 112 , that is, in the The suction end 11 of the suction body 10 and the end face of the camera device 30 are arranged on one side area, and the suction outlet 1302 is located on the other side area.

In one embodiment, the suction channel 130 can be communicated with a suction device 600, so that the sundries in the body can be quickly discharged by means of negative pressure suction. It is worth mentioning that the visual urinary tract lumen aspirator can enter the body through the mirror sheath 2P to attract gravel, so there is no need to use the gap formed by the mirror sheath 2P and the flexible mirror 1P to discharge gravel. , and the suction main body 10 can extend inward along the mirror sheath 2P, so that the visual urinary tract lumen suction device 100 is close to the position where the gravel stays, and the gravel is attracted at a short distance, so that the suction efficiency is greatly improved, It is easy to control the size of the attraction.

Referring to FIG. 1 , the handle 20 has a suction interface 24 , the suction interface 24 communicates with the suction channel 130 , and the suction interface 24 is used for connecting the suction device 600 .

The handle 20 further includes a control hole 26 for adjusting the operation of the suction channel 130 . For example, when the control hole 26 is pressed, the suction channel 130 is in a working state, that is, in a state of attracting gravel debris, and when the control hole 26 is released, or in a natural state, The suction channel 130 is in a non-working state, that is, stops attracting and discharging debris.

In one embodiment of the present invention, the cross section of the suction channel 130 is substantially oval, and the suction outlet 1302 is substantially oval, so as to maximize the use of the space position of the suction body 10, so that the suction The internal space of the channel 130 is maximized, and the effective space for waste discharge is increased, so that the sundries in the body can be discharged more quickly, the formation of water accumulation in the body is avoided, and the residue is reduced. In other embodiments of the present invention, the cross-section of the suction channel 130 may also be in other shapes, such as a semicircle or a fan-shaped area. In other embodiments, under the condition that the structural strength requirements of the suction main body 10 are met, the area outside the camera device 30 of the auxiliary channel can be used as the setting area of the suction channel 130 .

It is worth mentioning that the drainage channel of the traditional sheathed soft mirror is roughly annular, and the space that can be used is only an annular gap, so the drainage efficiency is very low, and the gravel is prone to blockage, while the technology of the present invention In the solution, the independent and hollow structural design of the suction channel 130 is used to maximize the effective space of the suction channel 130, thereby reducing the blockage of gravel, and enabling the debris to be discharged smoothly and quickly.

Further, in this embodiment of the present invention, the forming area of the camera device 30 extends outwardly convexly. That is to say, the first working area 111 protrudes outwardly. The first working area 111 and the second working area 112 form a substantially rounded step structure. It is worth mentioning that the roughly stepped structure formed by the first working area 111 and the second working area 112 reduces the effective contact area of the ends, thereby making it more convenient for the attracting body 10 to enter the body or in other words, the body. move.

For example, when the stone crushing operation is performed, the position corresponding to the first working area 111 is crushed and flushed, and the crushed stone and waste water will fall downward. The second working area 112 quickly sucks the sundries, and because the position of the camera device 30 has a predetermined distance from the suction inlet 1301, the suction inlet 1301 will not be directly too close to the internal organs, nor will it Direct contact with gravel to prevent damage to internal organs caused by attraction.

On the other hand, the camera device 30 is located in the first working area 111 , and the camera device 30 can strengthen the hardness of the first working area 111 to facilitate the entry of the suction end 11 of the suction body 10 into the body.

Preferably, the identifier 16 is located on the outer layer 15 and is of a different color from the outer layer 15 .

Referring to FIGS. 7A-7C, it is a schematic diagram of a usage process of the visual urinary tract lumen aspirator 100 according to an embodiment of the present invention. Take the process of using the visual urinary tract suction device 100 to treat stones in the renal pelvis as an example.

The first is to use the existing flexible ureteroscope 1P and the scope sheath 2P for lithotripsy. For example, the guide wire 4P is passed through one of the working channels of the flexible ureteroscope 1P, and the flexible ureteroscope 1P with the guide wire 200 is sent to the flexible ureteroscope 1P. into the body, and make the guide wire 200 enter the ureter, then insert the scope sheath 2P and the inner core 3P along the guide wire 4P, insert the scope sheath 2P to a position 0.5-1 cm away from the stone, and then exit the inner core 3P Then, the flexible ureteroscope 1P is sent into the scope sheath 2P, and the flexible ureteroscope 1P is close to the calculus, and a treatment device 5P is passed through a working channel of the flexible ureteroscope 1P, and the lithotripsy device is passed through the lithotripsy device. 5P performs operations such as flushing water, crushing stones, etc.

After lithotripsy, the flexible ureteroscope 1P is pulled out of the scope sheath 2P, and is placed in the visual urinary tract lumen suction device 100 along the scope sheath 2P. The in-vivo image collected by the camera device 30 is displayed through the display device 400 ; after the suction subject 10 reaches a predetermined position, the operator controls the suction subject 10 by controlling the handle 20 according to the image displayed on the display device 400 . The suction end 11 is close to the position of the crushed stone, and the suction process is controlled by controlling the control hole 26, and the crushed stone is sucked out from the suction channel 130 by means of the suction device 600. Observed through the display device 400, when the crushed stone is attracted After that, the handle 20 is controlled, and the suction body 10 can be directly pulled out of the scope sheath 2P.

It is also worth mentioning that the visual urinary tract lumen suction device 100 cooperates with the existing mirror sheath 2P to absorb the gravel in the body during use, so that the working size can be greatly increased without increasing the working size. The effective size of the stone discharge enables the larger size of the crushed stone to be quickly discharged without powdering the crushed stone, which reduces the energy loss of the crushed stone in the early stage. When attracting, the operation can directly observe the position of the crushed stone, and directly With the handle 20, the suction position can be adjusted, so that the suction of the crushed stone is more targeted, the residue of the crushed stone is reduced, and the waste can be discharged in time, reducing the possibility of the residue of the crushed stone.

It is also worth mentioning that the suction outlet 1302 of the visual urinary tract lumen aspirator 100, that is, the debris discharge outlet, can be close to the position of the gravel, so that debris can be attracted at a close distance, thereby reducing the negative pressure. When attracting, the size of the attraction can be better controlled, so that a smaller attraction can achieve a better attraction effect, thereby reducing the damage to the body caused by negative pressure attraction.

It is also worth mentioning that in the process of using the existing ureteroscope, it is necessary to discharge the gravel with the assistance of the mirror sheath, the efficiency of stone discharge is low, and the discharge space is small, so in order to discharge the gravel as much as possible, It is necessary to pulverize the crushed stone, that is, to make the size of the crushed stone as small as possible, such as smaller than the width of the gap, and the size of the existing stone crushing equipment cannot reach such a small size at one time, so it is necessary to repeat Crushed stone, that is to say, the broken stone needs to be broken again. In this case, the stones of various sizes are actually mixed with each other, so the stone crushing efficiency will be further reduced, and it may be necessary to repeat the work several times. A lot of crushed stones are discharged, so the energy loss of the whole process is relatively large, and the work efficiency is relatively low, and the operation time is relatively long, and in the embodiment of the present invention, the visual urinary tract lumen suction device The effective space for stone removal is greatly improved, so that powdered stones do not need to be powdered, and larger-sized stones can also be discharged, reducing energy loss and operation time.

Preferably, the corner positions of the first working area 111A and the second working area 112A are provided with rounded corner structures, which further facilitates the entry of the end of the attracting body 10A.

Further, from the first working area 111A to the second working area 112A from the outer end to the inward direction, the outer circumference of the cross section gradually shrinks, for example, forming a structure similar to a duckbill, so as to facilitate the attraction body 11A entry.

It is also worth mentioning that, as mentioned above, the first work area 111A and the second work area 112A are work areas for two functions, so the partitions are set so that the two functions can be independent of each other, while the first work area 112A is a work area for two functions. The roughly stepped structure of the first working area 111A and the second working area 112A further differentiates the functions of the first working area 111A and the second working area 112A. For example, when the stone crushing operation is performed, the position corresponding to the first working area 111A is crushed and flushed, and the crushed stone and waste water will fall downward. At this time, the first working area 111A near the first working area The second work area 112A quickly sucks up the debris.

The hardness of the main skeleton 13A is greater than the hardness of the coating layer 14A, so that the overall hardness of the attracting body 10A is enhanced while maintaining a certain flexibility of the attracting body 10A, so that the attracting body 10A has better orientation. For example, but not limited to, the main frame 13A is made of a metal material, and the cladding layer 14A is made of a plastic material. It is worth mentioning that, in this way, the soft and hard materials are combined with each other, so that the flexible mirror and the semi-hard mirror can be oriented at the same time, so that the attracting body 10A can enter and exit human organs independently.

The movable gap facilitates the bending of the attracting body 10A or has better flexibility. For example, when the suction body 10A encounters a bending position, the covering layer 14A of the suction body 10A and the main frame 13A are integrally bent, the first tube body 17A, the second tube The suction tube body 18A and the suction tube body 19A are respectively bent, the covering layer 14A and the main frame 13A limit the bending range of the suction tube body 19A, and the covering layer 14A and the main frame 13A, And the suction tube body 19A can be bent adaptively instead of being forced to bend together. It is also worth mentioning that the manufacturing materials of the coating layer 14A and the suction tube body 19A are different, so the forces generated by each are different in bending, and the relatively movable contact methods make these forces with different strengths. The attraction body 10A can be easily damaged due to local stress concentration during bending, which can be reconciled, avoided or reduced.

Further, in an embodiment of the present invention, the visual urinary tract lumen aspirator 100A includes an outer layer 15A, and the outer layer 15A is attached to the outer surface of the suction body 10A for improving the suction The surface properties of the main body 10A, for example, the outer layer 15A is used to enhance the surface flatness of the suction main body 10A, so that the surface of the suction main body 10A is smoother, so that it can easily enter the body.

Preferably, the outer layer 15A is a super slip coating for reducing the external surface resistance of the attracting body. In one embodiment, the outer layer 15A is formed on the outer surface of the attracting body 10A by plasma enhanced chemical vapor deposition. It is worth mentioning that forming a nano-coating on the surface of the attracting body 10A by means of plasma-enhanced chemical vapor deposition can greatly improve the smoothness of the surface of the attracting body 10A, and the thickness of the nano-coating is very thin. , will not affect the overall hardness of the attracting body 10A.

Further, in an embodiment of the present invention, the attracting body 10A has an identifier 16A, and the identifier 16A is disposed on the outer surface of the attracting body 10A. The identifier 16A is by way of example but not limited to a scale identification. It is worth mentioning that the identifier 16A cooperates with the camera device 30A to assist the operator in performing surgical operations. For example, when the operator uses the camera device 30A to observe the image information in front of the suction end 11A of the suction body 10A, and observe the depth of entry through the identifier 16A, so as to better determine the treatment position . Preferably, the identifier 16A is located on the outer layer 15A and is of a different color than the outer layer 15A.

Further, the camera device 30B is located above, close to the position of the back area 101B. The drainage channel 130B is located below, near the location of the abdominal region 102B.

It is worth mentioning that the different structures of the back area 101B and the abdominal area 102B are arranged corresponding to the working area of the attraction body 10B, or in other words, the upper and lower functions of the attraction body are distinguished.

For example, when entering, the back area 101B is located above, and the abdominal area is located below. When entering the bladder, the suction body 10B needs to be bent inward, that is, to the direction of the abdominal area 102B, so it is relatively The softer abdominal region 102B is more accommodating to the process of flexion of the medial side.

During stone ejection, the suction channel is located below, close to the abdominal region, so that the gravel can be supported by the mirror sheath 2P, that is, sent out along the channel provided by the mirror sheath 2P.

Preferably, the auxiliary channel 110 and the suction channel 130 are arranged side by side and isolated, that is, the auxiliary channel 110 and the suction channel 130 work independently of each other. For example, when the visual urinary tract lumen suction device 100 is used to treat calculus disease, a working instrument for lithotripsy penetrates from the auxiliary channel 110 to the suction end 11 of the suction body 10, or The water flows in from the outside through the auxiliary channel 110 , and is flushed out by the suction end 11 of the mirror body 10 to wash the crushed stones. When the crushed stone is suctioned, if it is found that the crushed or missed crushed stone is found in the early stage, the crushed stone can be performed again through the auxiliary channel during the suction, so as to reduce the residual stone.

Further, the auxiliary channel 110 is formed by an inner surface, and the inner surface material extends uniformly and integrally, that is to say, the inner surface is flat and has no uneven positions such as seams or protrusions, so as to facilitate work Smooth entry and exit of instruments. Preferably, the auxiliary channel 110 is a circular tubular channel, and correspondingly, the inner surface is an annular tube wall.

The auxiliary channel 110 has an auxiliary inlet 1101 and an auxiliary outlet 1102 , the auxiliary inlet 1101 communicates with the operating handle 20 , and the auxiliary outlet 1102 is located at the suction end 11 of the suction body 10 . The position of the auxiliary outlet 1102 is close to the outer end of the camera device 30, so as to facilitate visual operation.

The operating handle 20 includes an auxiliary interface, which is used to pass through the working instrument or through the guide wire or through the water flow. The auxiliary interface communicates with the auxiliary outlet.

Further, the auxiliary inlet and the camera capturing device 30 are arranged in the first working area 111 , and the suction port is arranged in the second working area 112 .

It is also worth mentioning that, as mentioned above, the first work area 111 and the second work area 112 are work areas of two functions, so the partitions are set so that the two functions can be independent of each other, while the first work area 112 is The roughly stepped structure of the first working area 111 and the second working area 112 further enables the functions of the first working area 111 and the second working area 112 to be differentiated. For example, when the stone crushing operation is performed, the position corresponding to the first working area 111 is crushed and flushed, and the crushed stone and waste water will fall downward. The second working area 112 quickly sucks the sundries, and because the flushed water of the auxiliary outlet, that is, the entering water, has a predetermined distance from the discharge position, that is, the suction outlet 1302, so the water that has just entered is prevented from When it is not used, it is discharged, so that the flushing process of gravel in the first working area 111 and the suction and discharge process of the working area are better isolated.

It is also worth mentioning that the space size of the suction channel 130 is larger than the space size of the auxiliary channel 110, and in the case of maximizing space utilization, it is adapted to the water inlet function and the discharge function respectively. For example, the auxiliary channel 110 is used for flushing water, that is, after crushing the stone, the crushed stone is washed, and a flowing medium is provided to send it out. During the operation, on the one hand, it is necessary to keep the lithotripsy instruments, such as the holmium laser. The working end face is clearly visible, which is convenient for the operator to clearly control the lithotripsy instruments. Therefore, the water flow cannot be made too large to avoid affecting the vision. On the other hand, the water flow is too large. It is easy to form water accumulation in the kidneys, which increases the pressure on the kidneys. Third, the incoming water is clear water, and the water flow is directly flushed into the body, so the water pressure cannot be too large, so the incoming water flow needs to meet the flushing conditions. The water flow requirement is relatively small, and the suction channel 130 needs to discharge the gravel debris as soon as possible, and the discharge is not clear water, but a mixture of impurities and water, so on the one hand, it needs to be discharged quickly, and on the other hand. On the one hand, it is required that large-sized gravel debris can pass through. Therefore, in the embodiment of the present invention, the auxiliary channel 120 and the suction channel 130 are functionally isolated from each other, the working areas are separated from each other, and the The size and functional requirements are matched to each other to improve the overall efficiency of stone crushing and stone removal.
