Description

Tube for partition working type ureteroscope and partition working type ureteroscope

Technical Field

The utility model relates to the field of medical equipment, especially, relate to pipe and subregion work formula ureteroscope for ureteroscope of subregion work.

Background

A ureteroscope is a device that can be inserted from the urethral opening to the ureter or to the renal site. Ureteroscopes are equipped with illumination, and lithotripsy devices so that during surgery a physician can use the ureteroscope to view the interior of the ureter or kidney and perform directional clearance of stones at some locations.

The ureteroscope can be mainly divided into a hard ureteroscope and a soft ureteroscope, wherein the hard ureteroscope has higher hardness, is difficult to bend, is suitable for being operated in a straight line or in a position with smaller bending, and has larger application limitation, and the soft ureteroscope can be bent to reach a position which is difficult to reach by the hard ureteroscope, so that the defects of the hard ureteroscope are overcome.

However, there are still some problems in practical use of soft lenses. In detail, the main components of the flexible ureteroscope include an operation portion, a sheath 1P and a flexible main body 2P, wherein the operation portion is generally disposed at the end of the flexible main body 2P exposed outside the body to operate the other end of the flexible main body 2P, and the flexible main body 2P is controlled to bend to smoothly enter a target position inside the patient body, however, since the flexible main body 2P is a flexible structure, it is necessary to expand the ureter by means of the sheath 1P to reach the target position.

The general operation process of the ureter soft lens is as follows, firstly, the lens sheath 1P is inserted from the urethral orifice by utilizing the guiding function of the guide wire, the soft lens main body 2P is inserted along the inner wall of the lens sheath 1P on the premise that the lens sheath 1P provides a passage with a proper size for the soft lens main body 2P, the front end of the soft lens main body 2P is controlled to be close to the calculus, a plurality of working channels are formed by utilizing the soft lens main body 2P to carry out the operations of flushing, calculus breaking and the like, and meanwhile, an annular passage is formed between the soft lens main body 2P and the lens sheath 1P to discharge water with the calculus. That is, for the entire ureteral soft lens, the discharge passage 10P is located between the soft lens body 2P and the lens sheath 1P, and the water inlet passage is located in the soft lens body 2P. The discharge of the ureter soft lens depends on the space formed by the outer wall of the soft lens main body 2P and the inner part of the lens sheath 1P, the sizes of the soft lens main body 2P and the lens sheath 1P are smaller due to the limitation of the size of the ureter, and the space for actually supplying drainage or removing the calculus is not large due to the annular design of the discharge channel 10P. In addition, because the soft lens main body 2P is bendable, the form of the soft lens main body 2P has uncertainty under the influence of various factors when inside the lens sheath 1P, the distance between the outer wall of the soft lens main body 2P and the inner wall of the lens sheath 1P can be far at some positions to facilitate the passage of broken stones, and the distance between the outer wall of the soft lens main body 2P and the inner wall of the lens sheath 1P is near at some positions due to the fact that the soft lens main body 2P is bent, which may cause broken stone blockage.

Referring to fig. 1, during the lithotripsy, a holmium laser 3P of the soft lens body 2P may protrude from the distal end of the lens sheath 1P to lithotripsy a hard region which is difficult to reach by the lens sheath 1P, which also means that the lithotripsy may be jammed between the soft lens body 2P and the lens sheath 1P, thereby causing an obstruction to the movement of the soft lens body 2P. In the case of a serious blockage, the soft lens body 2P may not be able to move relative to the sheath 1P, and the soft lens body 2P and the sheath 1P need to be taken out at the same time, and the soft lens body 2P can be operated again to move relative to the sheath 1P after the stones causing the blockage are cleaned. This requires the patient to re-undergo insertion of the sheath 1P, potentially increasing the risk of infection.

Further, during lithotripsy, since the soft lens body 2P extends outward from the distal end of the sheath 1P, the inlet of the annular discharge passage 10P is located at the end of the sheath 1P rather than the end of the soft lens body 2P. That is, the entrance position of the discharge passage 10P is located at a distance from the position where the soft lens body 2P performs lithotripsy, or a large distance exists between the lithotripsy working area and the discharge working area, which means that after the stone is fragmented at the distal end position of the soft lens body 2P, it needs to be sucked to the entrance of the discharge passage 10P by remote suction to be discharged. Obviously, this way requires the ureteroscope to provide a large suction force so that the crushed stones farther from the discharge channel 10P can be sucked to the inlet position of the discharge channel 10P. In this process, the control of the attraction is particularly critical, if it is too large, it is liable to cause damage to the body organs, and if it is too small, the crushed stones cannot be completely cleared.

Referring to fig. 2A to 3C, a regionally operating ureteroscope 1 according to a preferred embodiment of the present invention is illustrated.

The partition-working ureteroscope 1 can be applied to treatment of ureteral diseases, and a person skilled in the art can understand that the partition-working ureteroscope 1 can also be used for treatment of other diseases according to requirements.

The zone-working ureteroscope 1 need not be provided with a separate scope sheath, but is itself provided with a discharge channel. In other words, the ureteroscope 1 of the partition operation type can be directly inserted into the ureter for operation without entering the ureter with a sheath when being operated. It will be appreciated that the traditional approach of using a sheath to first enter the ureter is in fact a blind operation, and that the operator can easily cause damage to the ureter by inserting the sheath along the ureter without knowing the internal state of the patient. The partition-working ureteroscope 1 can be directly inserted into a ureter, and because the end of the partition-working ureteroscope 1 can collect information, the operations are completed under visualization, and the damage to a patient can be reduced as much as possible.

In detail, the ureteroscope 1 may include a main body 10 and an operation portion 20, wherein the operation portion 20 is disposed at an operation end 1002 of the main body 10 to control an operation end 1001 of the main body 10. The operation end 1002 and the working end 1001 are both ends of the mirror body 10, respectively.

The scope body 10 may include a tube 11 for a segmented-action ureteroscope and at least one working element 12, wherein the working element 12 may be attached to the tube 11 for the segmented-action ureteroscope, and the working element 12 may be, but is not limited to, a guide wire 100, an inner core 200, and a holmium laser 300. The guide wire 100 can guide the mirror body 10 into a target position, and the holmium laser 300 can be used for lithotripsy. It should be understood by those skilled in the art that the type of the working component 12 may be different according to the application scenario of the zone-work ureteroscope 1, and the operator may select the type according to the needs. Note that the working element 12 may be a member that is associated with the tube 11 for the ureteroscope and may be a member 12 that is currently available on the market.

The mirror body 10 is formed with at least a water inlet passage 110, a water outlet passage 120, and a working passage 130, wherein the working member 12 can be installed through the water inlet passage 110, the working passage 130 is used for water inlet, and the water outlet passage 120 can be used for water outlet or debris discharge. In this embodiment, the water inlet channel 110, the discharge channel 120 and the working channel 130 are independent of each other, and the number of the water inlet channel 110, the number of the discharge channel 120 and the number of the working channel 130 are respectively one. According to another embodiment of the present invention, two channels of the water inlet channel 110, the discharging channel 120 and the working channel 130 may share one channel, for example, refer to fig. 13A to 13C, the water inlet channel 110 and the working channel 130 may share one channel, the discharging channel 120 is independent of the water inlet channel 110 and the working channel 130, or the working channel 130 and the discharging channel 120 share the same channel, and the water inlet channel 110 is independent of the discharging channel 120 and the working channel 130. That is, the mirror body 10 may be a two-channel design, a three-channel design, or a more-channel design.

Further, in the present embodiment, the water inlet channel 110, the exhaust channel 120 and the working channel 130 may respectively extend between the working end 1001 and the operation end 1002 of the mirror body 10.

In more detail, the inlet channel 110 has an inlet outlet 1101 and an inlet 1102, wherein the inlet 1102 and the outlet 1101 are connected to each other, the inlet 1101 can be disposed at the working end 1001 of the mirror body 10, and the inlet 1102 can be disposed at the working end 1002 of the mirror body 10. The discharge channel 120 has a discharge outlet 1201 and a discharge inlet 1202, wherein the discharge inlet 1202 and the discharge outlet 1201 are capable of communicating with each other, the discharge inlet 1202 may be provided at the working end 1001 of the mirror body 10, and the discharge outlet 1201 may be provided at the operating end 1002 of the mirror body 10. The working channel 130 has a working inlet 1302 and a working inlet 1301, the working inlet 1302 and the working inlet 1301 being capable of communicating with each other, the working inlet 1302 being arranged at the working end 1002 of the mirror body 10, the working inlet 1301 being arranged at the working end 1001 of the mirror body 10.

In other words, the water inlet 1101 of the water inlet channel 110, the water outlet 1202 of the water outlet channel 120 and the working inlet 1301 of the working channel 130 of the mirror body 10 can all be located at the working end 1001 of the mirror body 10.

When the partition working ureteroscope 1 is operated, after the partition working ureteroscope 1 is introduced into a kidney, water flows to the working inlet and outlet 1301 through the working inlet 1302 of the working channel 130 and then enters the kidney, and a stone crushing component extends from the water inlet 1102 of the water inlet channel 110 to the water inlet and outlet 1101 and then enters a target position in the kidney to perform stone crushing operation. Excess moisture and debris may flow from the discharge inlet 1202 to the discharge outlet 1201 of the discharge passage 120, exiting the patient's body.

Since the discharge inlet 1202 of the discharge passage 120 and the inlet water outlet 1101 of the inlet water passage 110 are both located at the working end 1001 of the mirror body 10, at least a portion of the mirror body 10 close to the working end 1001 is 5-set bendable and can be operated by the operating portion 20, so that when the working end 1001 is operated to be close to a target position, the discharge inlet 1202 follows the inlet water outlet 1101 of the inlet water passage 110 together close to a target position, and a small force applied to the discharge inlet 1202 of the discharge passage 120 can suck away crushed stones near the working end 1001. The discharge inlet 1202 may also be flexibly repositioned following the working end 1001 to accurately attract debris or other debris. In this way, on the one hand, the cleaning of the gravels, especially the gravels hidden in the hidden positions, is facilitated, and on the other hand, the damage to the viscera is facilitated to be reduced.

Further, referring back to fig. 3A, the mirror body 10 has a first working area 101 and a second working area 102, wherein the water inlet 1102 of the water inlet channel 110, the water outlet 1202 of the water outlet channel 120 and the working inlet 1301 of the working channel 130 are arranged in the first working area 101 and the second working area 102. The arrangement of the first working area 101 and the second working area 102 allows the working end 1001 of the scope body 10 to be kept at a smaller cross-section than the other parts of the scope body 10 extending from the working end 1001 and the handling end 1002, so that the scope body 10 can be more easily introduced into the patient.

In detail, the tube 11 for the ureteroscope of the scope body 10 has a working end surface 111, wherein the working end surface 111 forms the first working area 101 and the second working area 102.

The water inlet 1101 of the water inlet channel 110, the outlet 1202 of the outlet channel 120, and the working inlet 1302 of the working channel 130 may all be located on the working end surface 111.

In more detail, the working end surface 111 includes a first partial working end surface 1111, a connecting surface 1112, and a second partial working end surface 1113, wherein the first partial working end surface 1111 is connected to the second partial working end surface 1113 through the connecting surface 1112. The first working end surface 1111 protrudes from the second working end surface 1113. Preferably, the first partial working end surface 1111, the connection surface 1112 and the second partial working end surface 1113 are respectively provided in an arc shape to facilitate smooth entry and exit inside the human body. The first working region 101 can be located at the first partial working end surface 1111, the second working region 102 can be located at the second partial working end surface 1113, and the mirror body 10 extends from the second working region 102 in a length direction outward to form the first working region 101.

The first partial working end surface 1111 and the second partial working end surface 1113 have a height difference, the working inlet/outlet 1301 of the working channel 130 and the inlet/outlet 1101 of the inlet channel 110 may be formed at the first partial working end surface 1111, and the outlet/inlet 1202 of the outlet channel 120 may be formed at the second partial working end surface 1113. That is, the working inlet and outlet 1301 of the working channel 130 and the inlet outlet 1101 of the inlet channel 110 may be located in the first working area 101, and the outlet inlet 1202 of the outlet channel 120 may be located in the second working area 102. During the stone breaking process, stone breaking and water discharging are carried out at the position of the first working area 101 which is convex, and suction is carried out at the position of the second working area 102 which is concave for discharging. In this way, the work inlet and outlet 1301 in the protruding position can be made to send water as far forward as possible, reducing the possibility that water flowing out of the work inlet and outlet 1301 is directly discharged by the discharge inlet 1202 of the discharge passage 120.

In addition, the crushed stones in the first working area 101 can be automatically guided to the second working area 102 through the guiding function of the connecting surface 1112 to exit the patient through the discharge inlet 1202 of the discharge passage 120.

For the entire regionally operated ureteroscope 1, the working end 1001 of the regionally operated ureteroscope 1 may be arranged to be duckbilled, and the tube 11 of the regionally operated ureteroscope 1 may form a flat protrusion at the working end 1001, where the first working region 101 is located. The first working area 101 occupies a smaller area than the second working area 102. In other words, the second working area 102 occupies a larger area so that the discharge inlet 1202 of the discharge passage 120 can be set larger.

For the entire regionally working ureteroscope 1, the working end 1001 of the regionally working ureteroscope 1 may be arranged approximately stepwise, the first partial working end surface 1111 of the working end surface 111 of the tube 11 for the regionally working ureteroscope 1 may extend in an approximately horizontal position, the connection surface 1112 may extend in an approximately vertical position, the second partial working end surface 1113 may extend in an approximately inclined position, and the connection surface 1112 extends between the first partial working end surface 1111 and the second partial working end surface 1113, thereby forming an approximately stepped shape.

For the whole regionally operated ureteroscope 1, at least part of the working end surface 111 of the regionally operated ureteroscope 1 can be a bevel to form an end part with a gradually reduced cross section extending outwards from the regionally operated ureteroscope. The second working area 102 is located at an inclined portion of the working end surface 111 to facilitate providing a larger working area, for example, the discharge inlet 1202 is located at the working end surface 111 to facilitate obtaining a larger discharge inlet 1202. It is understood that the slope of the working end surface 111 does not refer to a plane surface, and may be a curved surface or a surface with undulations.

It is noted that the connection position between the working end surface 111 and the surrounding wall of the tube 11 for the regionally working ureteroscope is designed to be smooth and slippery, and the working end surface 111 itself is also designed to be smooth and slippery, so that when the regionally working ureteroscope 1 is inserted, the smooth working end 1001 can smoothly enter the patient to avoid damage to the body tissue of the patient.

It is to be noted that the tube 11 for the ureteroscope 1 forms the protrusion 114 at the working end 1001, and the protrusion 114 occupies only a small portion of the working end surface 111. When the ureteroscope 1 is inserted into a patient, the ureteroscope 1 is formed with the working end 1001 with a smaller size, and the protrusion 114 is first inserted into the patient, and then the entire working end 1001 is fed into the patient along the working end surface 111. In this way, on the one hand, the working-in-zone ureteroscope 1 is facilitated to enter the patient, and on the other hand, the risk of the entire working end 1001 of larger dimensions being suddenly introduced into the patient and being lost is reduced.

It should be noted that the water inlet of the working channel 130 and the water outlet of the drain channel 120 may be controllable, either manually by an operator or electronically, so that the operator may free his/her hands to focus on operating the holmium laser 300 or other working components 12.

Further, in the conventional ureteroscope, the discharge passage 120 is located between the sheath and the soft lens body, and is annular, and the gap between the discharge passage and the soft lens body is not large, so that the discharge passage is easy to cause blockage of crushed stones. In this embodiment, the cross-section of the discharge passage 120 may be configured to be circular and elliptical to provide a larger passage for the discharge of debris to reduce the likelihood of debris clogging.

In addition, in the conventional ureteroscope, the formation of the discharge channel 120 is limited to the movement of the sheath and the soft lens body, and therefore sometimes the discharge channel 120 is narrowed because the sheath or the soft lens body is bent at some position due to the bending. In the present embodiment, the discharge passage 120 is formed in the scope body 10, not limited to the scope sheath, and the probability of stenosis due to bending or movement can be reduced, and the size of the discharge passage 120 itself can be designed to be large, so that the crushed stone can be more easily discharged from the discharge passage 120.

It is noted that the size of the original ureteroscope is limited to the sheath plus the main body of the flexible ureteroscope, and in this embodiment, the size of the segmented working ureteroscope 1 is not limited by the sheath, that is, the size can be designed to be smaller, and the size of the discharge channel 120 is larger than that which can be designed before.

Further, the tube 11 for the partitioned working ureteroscope may form the water inlet passage 110, the discharge passage 120, and the working passage 130.

The outer wall of the tube 11 for the partition working ureteroscope is made smooth, at least, after entering the ureter, so that the partition working ureteroscope 1 can be smoothly put into and taken out of the human body. The material of the tube 11 for the segmental working ureteroscope may be smooth in nature, and the outer wall of the tube 11 for the segmental working ureteroscope may be smooth after being processed by a process, such as a grinding process or a coating process. It will be understood by those skilled in the art that the foregoing is illustrative only and is not to be construed as limiting the invention.

The operation end 1002 and the working end 1001 of the scope body 10 are both ends of the tube 11 for the partition working ureteroscope. The entire outer surface of the portion of the tube 11 for the partitioned working ureteroscope extending between the operation end 1002 and the working end 1001 may have no port or a slit, so that the tube 11 for the partitioned working ureteroscope can be smoothly introduced into and removed from the human body. Optionally, the tube 11 for the partition working ureteroscope has a substantially circular cross section, so that the tube 11 for the partition working ureteroscope is uniformly stressed and the stress on the peripheral side is reduced.

Further, the operation portion 20 includes at least one operation element 21, and the operation element 21 is controllably connected to the working end 1001 of the mirror body 10. For example, when the working end 1001 of the mirror body 10 reaches a predetermined position, the user can operate the operation element 21 so that the end of the mirror body 10 is bent. In other words, the operating element 21 controls the bending work of the outer end portion of the mirror body 10.

In an embodiment of the present invention, the ureteroscope 1 may include a control wire, the control wire is preset inside the scope body 10 and extends along the scope body 10, when the operation element 21 of the operation part 20 is rotated, the control wire pulls the working end 1001 of the scope body 10, so that the end of the scope body 10 is controlled to rotate in a predetermined direction by the operation part 20.

Further, the operation portion 20 may further include a plurality of interfaces for passing or connecting other components, such as the guide wire 100, the core 200, the holmium laser 300, the lithotripter, the flushing device 4, the suction device 3, and the like. For example, the operation portion 20 includes a first port 22, a second port 23 and a third port 24, the first port 22 is communicated with the water inlet passage 110, the second port 23 is communicated with the working passage 130, and the third port 24 is communicated with the water outlet passage 120. For example, the first port 22 is used for passing through the working device 2, the second port 23 is used for connecting with the flushing device 4, and the third port 24 is used for passing through the guide wire 100, the inner core 200 and connecting with the suction device 3.

The operation portion 20 may further include an information interface 25, and a display device 5 may be connected to the information interface 25 so as to be communicatively connected to an image capturing assembly 13, i.e., information captured by the image capturing assembly 13 may be displayed through the display device 5.

The operating portion 20 further includes an adjustment hole 26, and the adjustment hole 26 is used to adjust the operation of the discharge passage 130. For example, when the adjusting hole 26 is pressed, the discharging passage 130 is in an operating state, i.e., a state of sucking the crushed stone and sundries, and when the adjusting hole 26 is released, or in a natural state, the discharging passage 130 is in an inactive state, i.e., the sucking and discharging of the sundries are stopped.

Further, the image capturing assembly 13 may include at least one image capturing device and at least one illuminator, wherein the illuminator provides light to the image capturing device, so that the image capturing device can capture the image of the inside of the human body smoothly.

The image capturing assembly 13 may be mounted on the working end 1001 of the ureteroscope tube 11 of the scope body 10, and for example, the capturing position of the image capturing device may be set in the protruding first working area 101, so that the image capturing device can capture the image information of the foremost end of the scope body 10 at all times. The image acquisition assembly 13 may be integrated into the tube 11 for the partition-work ureteroscope, or the tube 11 for the partition-work ureteroscope may provide a special water inlet channel 110 for the image acquisition assembly 13. That is, the image capturing assembly 13 may be either a stand-alone type or an integrated type. The image collector and/or the illuminator, which may be the image collecting assembly 13, are integrated or are provided separately.

Further, the image acquisition assembly 13 of the ureteroscope 1 may be communicatively connected to a display device 14, so that the image acquired by the image acquisition assembly 13 may be displayed on the display device 14 to be viewed by an operator. It is understood that the display device 14 can be a stand-alone device or can be integrated into the zoned-work ureteroscope 1, for example, at the position of the operation end 1002 of the scope body 10.

Referring to fig. 4A and 4B, a variation of the zoned-work ureteroscope 1 according to the above preferred embodiment of the present invention is illustrated. In this embodiment, the discharge inlet 1202 of the discharge passage 120 is disposed in the first working area 101, and the working inlet 1302 of the working passage 130 is disposed in the second working area 102. The water inlet passage 110 may be provided to the first working area 101 or the second working area 102. The image capturing assembly 13 may be disposed in the first working area 101 or the second working area 102.

Referring to fig. 5A and 5B, another embodiment of the zoned-work ureteroscope 1 according to the above preferred embodiment of the present invention is illustrated.

The present embodiment is different from the above-described embodiments mainly in the tube 11 for the partition operation type ureteroscope of the partition operation type ureteroscope 1.

The working end surface 111 of the tube for the partitioned working ureteroscope is an inclined surface, and it is understood that the working end surface 111 can be a smooth plane or a smooth cambered surface.

The inclined working end surface 111 gradually reduces the cross section of the end of the tube 11 for the partition-working ureteroscope outward, thereby facilitating the entry of the tube 11 for the partition-working ureteroscope into the patient.

The first working area 101 is arranged outside with respect to the second working area 102, that is, when the tube 11 for the divisional-working ureteroscope is inserted into the patient, the first working area 101 is first brought into contact with the patient, and then the second working area 102 is inserted into the patient.

The image capturing assembly 13 may be disposed in the first working area 101 to capture the frontmost image information in time. The working inlet and outlet 1301 of the working channel 130 and the inlet and outlet 1101 of the inlet channel 110 may be located in the first working area 101. The discharge outlet 1201 of the discharge channel 120 may be located at the second working area 102.

It will be appreciated that the end of the tube 11 for the segmented working ureteroscope may be smooth and have no sharp shape to minimize the possibility of injury to the body.

Referring to fig. 6A and 6B, another embodiment of the zoned-work ureteroscope 1 according to the above preferred embodiment of the present invention is illustrated.

In this embodiment, at least a portion of the working end surface 111 of the tube 11 for the partition-work ureteroscope protrudes outward to form a protrusion 114, wherein the first working area 101 and the second working area 102 are respectively located on two sides of the protrusion 114.

The working inlet and outlet 1301 of the working channel 130 may be disposed at the first working area 101, the discharge inlet 1202 of the discharge channel 120 may be disposed at the second working area 102, and the protrusion 114 may play a certain blocking role between the first working area 101 and the second working area 102.

The moisture flowing out of the work inlet and outlet 1301 flows forward as much as possible due to the blocking action of the protrusion 114, thereby reducing the chance of the moisture flowing directly out of the discharge inlet 1202. The crushed stones drawn toward the discharge inlet 1202 by the discharge inlet 1202 are not introduced into the working channel 130 through the working inlet 1302 by the blocking action of the projection 114, especially in the case where the water supply to the working channel 130 is stopped, thereby preventing the crushed stones from being inadvertently introduced into the working channel 130 to block the working channel 130. Preferably, the cross-section of the discharge channel 120 is larger than the cross-section of the working channel 130 to facilitate providing sufficient space to discharge waste such as water and debris.

The image capturing assembly 13 may be disposed in the first working area 101 together with the working inlet/outlet 1301, or the image capturing assembly 13 may be disposed in the second working area 102 or the protrusion 114.

The water inlet 1101 of the water inlet passage 110 may be disposed in the first working area 101 together with the working inlet 1301, or the water inlet 1101 of the water inlet passage 110 may be disposed in the protrusion 114.

It is noted that the corners of the connecting positions of the first working area 101 and the protrusions 114 are preferably rounded, and the corners of the connecting positions of the second working area 102 and the protrusions 114 are preferably rounded, so as to facilitate the safe access of the regionally operated ureteroscope 1 to the patient.

Further, referring to fig. 7, the tube 11 for a segmental working ureteroscope may include a tube body 112 and a support member 113, wherein the water inlet passage 110, the water outlet passage 120 and the working passage 130 are disposed on the tube body 112, and the support member 113 is disposed on the tube body 112 and can support the tube body 112. Preferably, the inner wall of the pipe body 112 is provided to be smooth to form the water inlet passage 110, the discharge passage 120, and the working passage 130, respectively. Alternatively, the cross-sections of the water inlet passage 110, the discharge passage 120, and the working passage 130 may be circular or elliptical.

The material of the support member 113 and the tube body 112 may be the same or different. The support member 113 may be bendable, and the tube body 112 may be bendable. The tube 11 for the divisionally-operated and divisionally-operated ureteroscope of the scope main body 10 is operably connected to the operation unit 20. When the tube 11 for the divisionally working ureteroscope is manipulated and then bent at the working end 1001 side, the tube main body 112 may be bent to bring the support member 113 into synchronous bending. It is understood that the tube main body 112 may include a passive bending portion and an active bending portion, both of which may be bent along the surface of the human organ, but the active bending portion may be manipulated through the operating part 20 so as to actively perform bending according to the operator's expectation.

The tube body 112 with the water inlet passage 110, the discharge passage 120, and the working passage 130 may be injection molded, or the like.

The supporting member 113 may include a coating 1131 and a main frame 1132, wherein the coating 1131 is disposed on the main frame 1132, the main frame 1132 has a certain rigidity to support, and the coating 1131 may be, but is not limited to, attached to the surface of the main frame 1132 by coating, injection molding, adhesion, or the like. The main frame 1132 may be formed by interweaving a plurality of supporting wires, and may be made of a metal material or a non-metal material.

The tube 11 for a segmental working ureteral mirror may be produced by forming the tube main body 112, then forming the main frame 1132 of the supporting member 113 on the outer side of the tube main body 112, and finally forming the coating layer 1131, thereby obtaining the tube 11 for a segmental working ureteral mirror. Of course, the tube 11 for the ureteroscope of the present invention is not limited to this, as will be described below by way of example.

Further, the main framework 1132 may have a hardness greater than that of the cladding 1131, so that the cladding 1131 provides a certain softness while maintaining a certain hardness through the main framework 1132. The coating 1131 can be made of plastic, the main framework 1132 can be embedded into the coating 1131, and the tube 11 for the subregion working type ureteroscope 1 has the flexibility of a soft lens and the guidance of a semi-hard lens in such a way that the subregion working type ureteroscope can conveniently enter and exit the human body. Preferably, the cladding 1131 is integrally formed on the main frame 1132.

Further, the overall hardness of the partition working ureteroscope 1 is arranged to be different. In detail, the scope body 10 of the regionally working, regionally working ureteroscope 1 is provided with different hardness at various positions so that different bending can occur during the tube entering process.

Further, referring to fig. 8, the tube 11 for the partition-working ureteral mirror of the mirror main body 10 includes a first tube portion 11A and a second tube portion 11B, wherein the first tube portion 11A is located at the front end, and the second tube portion 11B is located at the rear end and is close to the operation portion 20 with respect to the first tube portion 11A. The first pipe section 11A may be an active curved section, the curvature of which can be manipulated to actively change its curvature. The second pipe section 11B may be a passive bend, the bending of which passively changes with the surrounding environment.

In the present embodiment, the mirror body 10 is set to assume a state of soft front and hard back. It will be appreciated that for the zoned-working ureteroscope 1, which needs to be passed through the bladder, ureter and then to the kidney site, and needs to be crushed at various sites of the kidney, the first tube section 11A of the scope body 10 is provided to be softer to facilitate the alignment of the working end 1001 of the scope body 10 at various sites.

In other words, the first pipe section 11A is more easily bendable relative to the second pipe section 11B so that the first pipe section 11A may be brought into some more concealed position, and the second pipe section 11B is stiffer relative to the first pipe section 11A to facilitate operator control of pipe entry and subsequent depth of entry during operation, the stiffer allowing the operator to more precisely control the force.

The first tube section 11A comprises at least a portion of the tube body 112 and at least a portion of the support member 113, wherein the support member 113 comprises the cladding 1131 and the primary backbone 1132, wherein the primary backbone 1132 is configured by interweaving the support wires, and in this embodiment, the density of the support wires in the first tube section 11A is less than the density in the second tube section 11B, such that the stiffness of the first tube section 11A is less than the stiffness of the second tube section 11B.

It is understood that the density of the coating 1131 of the support member 113 of the tube 11 for the zoned-working ureteroscope may be different between the first tube part 11A and the second tube part 11B, and the density of the coating 1131 may be lower in the first tube part 11A than in the second tube part 11B, so that the hardness of the first tube part 11A is lower than that of the second tube part 11B.

Further, the hardness or flexibility of each position of the first pipe section 11A may be different. For example, the main frame 1132 of the supporting member 113 is arranged close to the front and close to the rear of the first pipe section 11A, so that the front end of the first pipe section 11A has a higher hardness than the rear end of the first pipe section 11A.

By the dense-front-back arrangement of the main frame 1132 of the supporting member 113 of the first tube portion 11A, the effect of large bending and small bending of the first tube portion 11B can be achieved at the same time, so as to adapt to the situation that the first tube portion 11B extends to different positions after entering the kidney.

Referring to fig. 12A to 12C, the first tube portion 11A of the tube 11 for the regionally working ureteroscope can be formed into a large curve when entering the ureter from the bladder. It is understood that the tube 11 for the divisional working ureteroscope has a certain hardness to maintain a desired curvature when the first tube part 11A is controlled to be bent to a certain degree, although it is arranged to be soft in the front and hard in the rear. When the first length of tubing 11A is advanced into the kidney for fragmenting a stone located at the suprarenal glenoid location, the first length of tubing 11A may be controlled to bend and may be controlled to bend to a lesser extent. When the first length of tubing 11A is advanced into the kidney for fragmenting a stone located at the location of the infrarenal pelvis, the first length of tubing 11A may be controlled to bend and may be controlled to bend by a greater extent.

It will be appreciated that while the zoned-working ureteroscope 1 is arranged to be soft front and stiff back, when the first tubing segment 11A is manipulated to achieve a desired degree of bending, its stiffness is increased to maintain the desired state of bending.

It is understood that the support member 113 of the scope 11 may be embodied in other forms. Referring to fig. 9 and 10, and first to fig. 9, the main bobbin 1132 of the support member 113 may include at least one longitudinally extending ridge 11321 and a plurality of transverse reinforcing ribs 11322, the longitudinally extending ridge 11321 extends along the length direction of the mirror body 10, and the transverse reinforcing ribs 11322 are curvedly connected to both sides of the main bobbin 1132. Preferably, the main frame 1132 includes two longitudinally extending ridges 11321 symmetrically distributed along the center of the mirror body 10, and a plurality of transverse reinforcing ribs 11322 are connected between the two longitudinally extending ridges 11321 in an arc shape, vertically symmetrical manner, or mirror-symmetrical manner. In one embodiment of the present invention, the transverse stiffener 11322 is of a bent structure, such as a wave-shaped structure. The backbone 1132 includes a series of transverse stiffening ribs 11322 arranged substantially parallel to each other between the two longitudinally extending ridges 11321. In one embodiment of the present invention, the transverse stiffening ribs 11322 are movably connected with the longitudinally extending ridges 11321 to facilitate bending of the mirror body 10.

It is worth mentioning that the arrangement of the longitudinally extending ridges 11321 and the transverse stiffening ribs 11322 provides the mirror body 10 with a certain flexibility for easy bending, and on the other hand, provides the mirror body 10 with a better guidance for direct access to the body without the aid of a sheath.

The density of the transverse stiffeners 11322 may be arranged to be different in the first tube portion 11A, and the closer to the working end 1001, the greater the density of the transverse stiffeners 11322 may be arranged, so that the first tube portion 11A may be formed with different bends.

Referring next to fig. 10, the main framework 1132 of the support member 113 may include a plurality of condyles 11323, and adjacent ones of the condyles 11323 may be configured to be rotatably coupled. The condyle 11323 may be configured to be shorter closer to the working end 1001 and shorter closer to the operating end 1002 of the first tube portion 11A, so that the rear end portion of the first tube portion 11A is more easily bent than the front end portion of the first tube portion 11A, thereby enabling the first tube portion 11A to form a large bend and a small bend. It is to be understood that the softness and hardness of the front and rear portions of the pipe main body 112 do not necessarily mean that the hardness of any position of the first pipe portion 11A is weaker than that of any position of the second pipe portion 11B. In this embodiment, the stiffness of each condyle 11323, whether it is in the first tubular portion 11A or the second tubular portion 11B, may be the same. In other words, the curvature of the first tube section 11A of the tube body 112 is greater than the curvature of the second tube section 11B.

It is understood that the main frame 1132 of the supporting member 113 may be disposed in the first pipe section 11A or the second pipe section 11B, and the arrangement in the two positions may be the same or different. For example, the main frame 1132 of the supporting member 113 is disposed at the first pipe portion 11A and the second pipe portion 11B, and is disposed at a higher density depending on the portion of the main frame 1132 at the second pipe portion 11B, so that the second pipe portion 11B has a smaller flexibility than the first pipe portion 11A, so that the second pipe portion 11B has a higher hardness than the first pipe portion 11A. For example, the main frame 1132 of the support 113 may be arranged identically at the location of the first pipe section 11A and the second pipe section 11B, and the first pipe section 11A and the second pipe section 11B may obtain different hardness or flexibility by virtue of the different coatings 1131 of the support 113.

Referring to fig. 11A to 11C, a working process of the ureteroscope 1 according to the above preferred embodiment of the present invention is illustrated, and the ureteroscope 1 is applied to treat a stone in a renal pelvis.

First, one end of a guide wire 100 is inserted along the ureter, then an inner core 200 is inserted along the guide wire 100, and finally, the tube 11 for the zoned-working ureteroscope of the scope body 10 of the zoned-working ureteroscope 1 is inserted along the inner core 200, either via the water inlet channel 110 or the drainage channel 120. In this process, an image of the peripheral path can be acquired by the image acquisition device provided to the tube 11 for the divisional-work ureteroscope, so that the operator can easily judge the position reached.

After the working end 1001 reaches the set position, the guide wire 100 and the inner core 200 can be removed from the water inlet channel 110 and then placed into a means for breaking stones, such as the holmium laser 300, for the breaking treatment of stones, while water is introduced through the working channel 130 to the kidneys, broken stones are discharged through the discharge inlet 1202 of the discharge channel 120 and drained to maintain the kidneys at a reasonable pressure.

It should be noted that since the discharge inlet 1202 of the discharge channel 120 and the water inlet 1102 of the water inlet channel 110 are both located at the working end 1001, the partition-working ureteroscope 1 can suck and discharge crushed stone with a small force. In other words, the operator does not need to concentrate excessively on controlling the change in the magnitude of the acting force to smoothly attract the crushed stones, and the difficulty of the operation is reduced.

It is worth mentioning that since the discharge channel 120 can be dimensioned larger and not annular, but to provide a complete space, for example a space with a circular cross-section, crushed stones can be discharged easily, reducing the possibility of the crushed stones blocking the discharge channel 120. It is also worth mentioning that the enlargement of the size of the discharge channel 120 may not have an influence on the overall size of the partition-working ureteroscope 1.

It is worth mentioning that, since the discharge inlet 1202 of the discharge channel 120 is located in the second working area 102, the working inlet 1302 of the working channel 130 is located in the first working area 101, and there is a distance therebetween, so that the moisture flowing out of the working channel 130 is released forward as far as possible, and then the surrounding moisture is driven to flow toward the discharge inlet 1202 of the discharge channel 120.

It is worth mentioning that, since the working end 1001 of the scope body 10 of the segmental working ureteroscope 1 is designed to be step-shaped, when the scope body 10 enters into the body along the guide wire 100 or other guiding component, the guide wire 100 or other guiding component is located in the water inlet channel 110 and the protruding portion of the working end 1001 can be supported by the guide wire 100 or other guiding component to facilitate the entering of the scope body 10. The working end 1001 of the scope body 10 is similar to riding on the guidewire 100 or other guiding component to facilitate entry of the scope body 10.

In addition, the image acquisition assembly 13 at the end can also acquire surrounding environment information at the front end, so that the operator can complete the endoscope entering in the visual environment.

It is worth mentioning that the discharge inlet 1202 of the discharge channel 120 of the segmented working ureteroscope 1 can be designed to be large, for example, to allow 1 mm to 2 mm, even 2.5 mm, and furthermore, since the discharge inlet 1202 is close to the position of the crushed stone, the stones can be easily drawn into the discharge channel 120 from the discharge inlet 1202.

Therefore, the requirement of the partition-working ureteroscope 1 for crushed stone is reduced, the combination can be sucked without being crushed to a small size and then discharged, in the current market, the combination is limited by the size of the discharge channel 120 and the size of the suction force, the combination can be sucked even after being powdered or hazed, and in the embodiment, the combination in a certain size range can be directly sucked without being crushed.

It is worth mentioning that the partition working ureteroscope 1 has higher working efficiency. In particular, since stones within a certain size range can be directly sucked away, an operator only needs to concentrate on larger stones during the operation, and the stones with larger sizes can be sucked away immediately after being broken. In current ureteroscopes, however, when stones are fragmented to a small size and cannot be discharged through the passage between the sheath and the outer wall of the soft lens body, such stones need to be removed from the passage in which the holmium laser 300 is located by means of a stone-removing basket. That is, the operator needs to pause the lithotripsy and then replace the holmium laser 300 with a stone basket to remove the stones, which certainly has a great influence on the working efficiency, especially when the number of stones of this size is large, the operator needs to repeat many times to remove the stones. If the partition-working ureteroscope 1 provided by the present embodiment is used, since smaller stones can be directly aspirated and, in addition, larger stones for the original ureteroscope can be also evacuated from the evacuation channel 120, the operator does not need to use a stone-evacuation basket to inefficiently evacuate stones one by one.

In other words, for the operator using the zoned-work ureteroscope 1, stones can be divided into two categories, stones that need to be broken and stones that can be directly aspirated away, so the operator only needs to concentrate on breaking large stones, so small stones can be directly evacuated through the evacuation channel 120 during the lithotripsy procedure.

In the existing stone operation, stones which an operator needs to face need to be divided into three types, stones which can be sucked away, stones which need to be broken, and stones which cannot be sucked away and are difficult to break, so that the operator needs to take a stone basket for assistance.

It is worth mentioning that, due to the design of the working end face, the first working area 101 and the second working area 102 are formed at different positions, and the first working area 101 protrudes from the second working area 102 and an inclined connecting surface 1112 capable of guiding exists therebetween. When the working inlet and outlet 1301 of the working channel 130 located at the first working area 101 is discharged, a vortex may be formed near the location of the first working area 101.

Further, due to the design of the front soft and rear hard of the ureteroscope 1, during the endoscope entering process, the endoscope body 10 which is not entered temporarily needs to be maintained in a stretched state like the traditional soft endoscope, so as to avoid the difficulty of passing the over-soft part through the endoscope sheath, and the endoscope body 10 can be directly inserted into the patient under the guiding action of a guide wire 100 and the like.

In addition, the end of the sectional-work ureteroscope 1 is bendable, and the curvature of the bending can be controlled to be large or small, so that when stones at different positions in the kidney are treated, different curvature controls can be adopted, and for stones at the infrarenal pelvis position, the first tube section 11A of the sectional-work ureteroscope 1 can form a large bending, and for stones at the suprarenal pelvis position, the first tube section 11A of the sectional-work ureteroscope can form a small bending.

Referring to fig. 13A to 13C, the partition working ureteroscope 1 according to another preferred embodiment of the present invention is illustrated. In this embodiment, the working channel 130 and the water inlet channel 110 share a channel, and the working end surface 111 is designed as a duckbill, it is understood that the working end surface 111 may be designed as in the above embodiments, for example, the whole working end surface 111 may be a slant surface, or the middle position of the working end surface 111 may be protruded to form the first working area 101 and the second working area 102 on two sides, respectively. With the zoned-working ureteroscope 1, the zoned-working ureteroscope 1 has a smaller end to facilitate access to the patient, while providing a larger drainage channel 120 to facilitate the drainage of larger stones.

It will be understood by those skilled in the art that the embodiments of the present invention as described above and shown in the drawings are given by way of example only and are not limiting of the present invention. The objects of the present invention have been fully and effectively accomplished. The functional and structural principles of the present invention have been shown and described in the embodiments without departing from the principles, embodiments of the present invention may have any deformation or modification.
