Description

Support tube, support kit and system with image capturing function

Technical Field

The invention relates to the field of medical instruments, in particular to a supporting tube, a supporting kit and a system with an image capturing function.

Background

Medical personnel treats to the patient in vitro, if the position that needs treatment is at the patient body surface, then medical personnel can directly exert corresponding utensil for treatment or treatment medicine at the patient body surface, if the position that needs treatment is in the patient internal, then medical personnel can just can treat to the internal target position of patient with the help of some professional utensil.

Further, if a medical staff wants to deliver a corresponding therapeutic device or a therapeutic drug from outside the body to a target site inside the body, the medical staff usually needs to travel a certain distance inside the body to reach the desired position by means of a natural or artificial passage. The natural channel is a channel naturally formed by a human body, and the medical staff can smoothly convey the target object to the target position along the natural channel by operating the appliance. The artificial passage is a passage formed in the acquired, and a medical staff can form a passage extending from the body surface to the body by operating an instrument, such as a puncture needle. In order to reduce the damage to the human body and also to reduce the difficulty of establishing the passageway, the operation of establishing the acquired passageway is generally as follows: a small-sized passage is established through the elongate member and a support tube having a larger cross-sectional dimension than the elongate member is then positioned along the elongate member or other guide member to establish a larger-sized working channel for placement of a corresponding medical instrument.

At present, there are many problems in such a way of establishing an operation channel, one of the problems is that blood vessels may be fully distributed around a small-sized channel established in advance, so that in the process of entering a support tube, medical staff cannot observe internal conditions to cause deviation of the position where the support tube enters, for example, the depth of the support tube entering may be too deep, so that a specific instrument is inserted into a non-target position, a patient may suffer from heavy bleeding due to the fact that the support tube is inserted into the blood vessel, even the support tube itself breaks the blood vessel to cause heavy bleeding, for example, the position of the support tube entering may be too shallow, so that related instruments or medicines cannot be sent to a proper position to play a role.

One way to solve the above problem is to mark the support tube and position the support tube during insertion using a B-ultrasonic machine or other positioning equipment so that the support tube is first mounted at the correct position and then the subsequent operation is performed with the mounted support tube. This solution has the problem that the support tube needs to be placed by the medical staff with the aid of additional equipment, and in general the equipment is of a flat type, i.e. the medical staff, although being able to know the approximate position of the support tube, still has the support tube inserted to an unintended position, for example, into a peripheral blood vessel, causing major bleeding.

Referring to fig. 1 to 5D, a supporting tube, a supporting kit and a system with image capturing function according to a preferred embodiment of the present invention are illustrated.

The system with image capturing function comprises the supporting member 1000, an image processor 2000 and a display 3000, wherein the supporting member 1000 comprises the supporting tube 1 and may further comprise a guide 2 and an image capturing member 3, wherein the image processor 2000 processes to obtain an image based on information captured by the image capturing member 3 of the supporting member 1000, and the display 3000 displays the image obtained by the image processor 2000. The image processor 2000 is communicatively coupled to the display 3000 and the support assembly 1000 is communicatively coupled to the image processor 2000.

At least a part of the support tube 1 can be fed into a body, such as a human or animal body, the guide 2 is adapted to be mounted to the support tube 1 of the support tube 1 to guide the support tube 1 to be mounted at a proper position in the body, and the image capturing member 3 is adapted to be mounted to the support tube 1 of the support tube 1 to capture environmental information about the environment around the support tube 1, particularly the advancing direction of the support tube 1, to visualize the mounting process of the support tube 1, thereby enabling the controllable mounting of the support tube 1.

In detail, the support tube 1 of the support tube 1 comprises a tube structure body 10 and a tube front end portion 20, the tube front end portions 20 being respectively arranged at one end of the tube structure body 10, wherein the support tube 1 has a mounting channel 100 and a working channel 200 and the mounting channel 100 and the working channel 200 are respectively adapted to extend from the tube structure body 10 to the tube front end portion 20 and through the tube structure body 10 and the tube front end portion 20.

The guide member 2 is adapted to be mounted to the mounting passage 100 of the support tube 1, and the image pickup member 3 is adapted to be mounted to the working passage 200. It is understood that the image capturing member 3 may be detachably disposed on the working channel 200, or may be fixedly disposed on the working channel 200, for example, integrally formed with the working channel 200.

The guide 2 is adapted to be inserted into the body to guide the support tube 1 later. There are many ways to insert the guide 2 into the body, for example, an elongated puncturing member which is relatively thin and has a certain hardness can be inserted into the body, then the guide 2 is inserted along the inside of the elongated puncturing member, and then the elongated puncturing member is pulled out, so that the guide 2 is detained in the body to be suitable for guiding the support tube 1 to be installed at a proper position in the body. The guide 2 is an elongated member that serves primarily as a guide and can be pulled out directly after use without causing damage to the body tissue. The material of which the guide 2 is made may be various, such as a metal material, a plastic material, etc., and is herein for illustrative purposes and not limited thereto.

The image capturing member 3 may include a connecting member 31 and an image capturing head 32, the image capturing head 32 being disposed at a front end of the connecting member 31 and adapted to capture image information. A rear end of the connecting member 31 may be connected to the image processor 2000 or an energy supply device, however, it is understood that the image capturing unit 3 may be an active device or a passive device, and the image capturing unit 3 and the image processor 2000 may be connected by wire or wirelessly. The image acquisition head end 32 may be integrated with a light source and a light sensor to acquire images with the aid of the light source. The light source is used for emitting light rays to irradiate the collected object, and the light sensor is used for receiving the reflected light rays to collect image information about the collected object.

Further, the image capturing element 3 may include an electronic sensor, for example, the optical sensor may be a camera, and may be, but is not limited to, a camera module composed of a lens and a CMOS image sensor, and may also be other types of sensors for capturing image information. The light source may be, but is not limited to, a led light source or a cold light source. The image capturing element 3 may comprise a fibre-optic sensor, which may be a pixel formed by a plurality of optical fibres.

Before the support tube 1 is inserted into the body, the image capturing member 3 is mounted in advance to the working channel 200 of the support tube 1. It is understood that the image capturing member 3 may be pre-integrated with the working channel 200 of the support tube 1, or the image capturing member 3 may be detachably mounted to the working channel 200 of the support tube 1. When the support tube 1 needs to be installed, the guide 2 is inserted along the installation channel 100 portion of the tube front end portion 20 of the support tube 1 to be fed along the guide 2 to the support tube 1 to a desired position with the aid of the image pickup member 3.

Further, the support tube 1 has a mounting port 101 and a working port 201, the mounting port 101 is formed at the tube front end portion 20 and communicates with the mounting passage 100, and the working port 201 is formed at the tube front end portion 20 and communicates with the working passage 200. The guide 2 is adapted to protrude from the mounting opening 101 and continue to extend forward, and the image capturing head end 32 is adapted to be mounted at the position of the working opening 201 of the support tube 1. The size and shape of the working port 201 may be arranged such that the image capture head 32 is securely mounted near the working port 201 to stably capture image information.

The installation opening 101 and the working opening 201 are designed such that the image capturing element 3 arranged in the working channel 200 can capture suitable image information to assist the support tube 1 in advancing the support tube 1 along the guide 2 while observing the image information of the guide 2 in the vicinity of the installation opening 101.

In detail, the mounting port 101 is provided to extend obliquely forward with respect to the working port 201. The direction of extension from one end of the support tube 1 towards the tube front end 20 is forward. Since the mount port 101 is arranged to extend forward, the guide 2 is mounted to the mount port 101 with a limit within a certain range, and therefore the guide 2 that comes out from the mount port 101 is allowed to extend forward under the restriction of the mount port 101.

After the image capturing member 3 is disposed on the support tube 1 and the guide 2 passes through the support tube 1, an angle is formed between an axis of the guide 2 at a portion of the tube front end portion 20 of the support tube 1 and an optical axis of the image capturing member 3. It is understood that this does not mean that the axis of the guide 2 at the portion of the tube front end 20 of the support tube 1 and the central axis of the image capturing member 3 meet at a position, for example, the axis of the guide 2 and the central axis of the image capturing member 3 may be non-parallel straight lines in two planes respectively.

Since the work port 201 is provided at the rear side of the mounting port 101, that is, the mounting port 101 is located at the front side of the work port 201, when the image pickup device 3 is operated, the position of the mounting port 101 located in front of the image pickup device 3 can be picked up. In some support tubes 1 of other types currently in use, the mounting opening 101 and the working opening 201 are arranged side by side or the mounting opening 101 is arranged behind the working opening 201, which makes it impossible for the image capturing element 3 mounted on the mounting channel 100 to capture an image of the position of the mounting opening 101.

In more detail, for the installation port 101 and the working port 201 which are arranged side by side, it is difficult for the image capturing member 3 to capture the image information of the installation port 101 or the working port 201, and since the installation port 101 and the working port 201 are arranged side by side, the cross-sectional area of the tube front end portion 20 is large, thereby increasing the difficulty of entering the support tube 1 into the body. Further, the installation port 101 and the working port 201 are arranged side by side, and the installation port 101 and the working port 201 are located at the foremost end of the support tube 1, and are the parts which enter the unknown region in the body at the earliest time, however, in the case where the image capturing element 3 cannot capture the working port 201 or the installation port 101, the image information captured by the image capturing element 3 arranged forward is the environmental information in front of the tube front end portion 20 of the support tube 1, in case the support tube 1 penetrates into the blood vessel around the guide 2 during the advancement, the image information acquired by the image acquisition member 3 may not prevent this in advance, since the mounting opening 101 and the working opening 201 are in a blind area with respect to the image capturing element 3.

In the case where the working opening 201 is arranged in front of the mounting opening 101, the image capturing element 3 captures mainly an image in front of the tube front end 20 of the support tube 1. In detail, the working port 201 and the mounting port 101 are disposed at the tube front end portion 20 and are disposed forward, the working port 201 is located forward of the mounting port 101, and the working port 201 corresponds to the foremost position of the entire support tube 1. Similarly, since the image capturing member 3 is mounted to the mounting passage 100 and may be at least partially located at the mounting opening 101 to capture an image forward, it is difficult for the image capturing member 3 to capture the position of the mounting opening 101 where it is located, and therefore there is still a possibility that the portion of the tube front end portion 20 of the support tube 1 forming the mounting opening 101 may be inserted into an unintended position, and although the support tube 1 is controllably advanced forward along the guide 2 in the display of the display 3000 at this time, the portion of the tube front end portion 20 of the support tube 1 forming the mounting opening 101 may have been inserted into a blood vessel in a visually blind position.

In the embodiment, the working opening 201 is arranged behind the installation opening 101, so that the foremost position of the support tube 1 is the installation opening 101, and the image acquisition part 3 arranged on the installation channel 100 can capture the image information of the installation opening 101 forward, so that the operator can observe the situation of the installation opening 101 and the situation of the guide part 2 extending from the installation opening 101, and therefore the support tube 1 can complete the whole installation process under the condition that the foremost position thereof is controllable. In this way, the installation process of the support tube 1 really realizes the visibility and the controllability of the head end, reduces the risk that the support tube 1 is inserted into an unexpected position in the installation process, and increases the safety of the whole intubation process.

Further, in the two previous arrangements of the mounting port 101 and the working port 201 mentioned above, the mounting channel 100 and the working channel 200 are arranged in parallel, whether in the mounting channel 100 and the working channel 200 portion of the tube structural body 10 or in the mounting channel 100 and the working channel 200 portion of the tube nose portion 20. This makes the optical axis center of the image pickup element 3 mounted to the mounting passage 100 and the central axis of the guide member 2 mounted to the working passage 200 parallel to each other. When the operator is installing the support tube 1, the guide 2 observed through the display 3000 is not at the visual center, which makes the operation of the operator difficult, that is, the guide 2 is always at the position below or above the visual center or at the position left or right in the display 3000, and the operator needs to complete the installation of the support tube 1 along the guide 2 offset in the visual sense.

In the present embodiment, the guide member 2 protruding from the mounting port 101 is arranged obliquely with respect to the mounting port 101 or the mounting passage 100 so that the guide member 2 can be observed at the optical axis center of the image pickup member 3. In other words, the operator can observe the guide 2 located at the visual center on the display 3000 while operating the support tube 1, to facilitate the operation of the operator.

In detail, the installation passage 100 at the tube front end portion 20 of the support tube 1 is provided to be obliquely arranged and obliquely arranged forward toward the direction in which the working passage 200 is located. The guide 2 projecting from the mounting opening 101 may be inclined under the constraint of the mounting channel 100 and/or the mounting opening 101. It is understood that the orientation of the guide 2 can be restricted by the installation channel 100 alone, the installation opening 101 alone, or the combination of the installation channel 100 and the installation opening 101.

Further, in order to facilitate the support tube 1 to be easily fed into the body, the tube front end portion 20 of the support tube 1 is designed to be small in size with respect to the tube structure body 10 so that the head end of the support tube 1 is easily fed into the body.

In this embodiment, the installation channel 100 at the tube front end 20 is arranged to be inclined towards the working channel 200, which is advantageous for reducing the size of the tube front end 20, on the one hand, facilitating the delivery of the support tube 1 into the body, and on the other hand, reducing the possibility of tissue damage in the body due to the large size of the support tube 1 relative to the previously established channel. In other words, in the present embodiment, since the working channel 200 and the installation channel 100 are arranged more compactly at the position of the tube front end portion 20, the tube front end portion 20 of the support tube 1 can be designed to be smaller in size. It is noted that the support tube 1 has a front end and a rear end, the front end and the rear end are oppositely disposed, the front end of the support tube 1 is located at the tube front end portion 20, the rear end of the support tube 1 is located at the other end, in this embodiment, the closer to the front end of the support tube 1, the closer the distance between the working channel 200 and the installation channel 100 is, and thus the closer to the front end of the support tube 1, the smaller the size of the support tube 1 can be designed to facilitate the entry of the support tube 1 into the body.

Further, referring to fig. 8A, 8B and 8C, fig. 8A and 8B show two existing arrangements of the mounting port 101 and the working port 201 of the support tube 1, respectively, one is that the mounting port 101 and the working port 201 are arranged side by side, and the other is that the mounting port 101 is arranged behind the working port 201. Fig. 8C shows the arrangement of the mounting port 101 and the working port 201 of the support tube 1 in the present embodiment, and the mounting port 101 is arranged in front of the working port 201.

In the comparative tests of the above three, it is obvious that there is a violent shake of the two support tubes 1 illustrated in fig. 8A and 8B passing through the guide member 2 of the support tube 1 during the tube feeding process, and the guide member 2 is directly exposed, so that once the guide member 2 is squeezed by the front tissue, the guide member 2 may disappear in the visual field, and the operator cannot judge the current situation.

In fig. 8C, the supporting tube 1 is provided with a protruding tube wall 30 around the guide 2, on one hand, the tube wall 30 is visible in the field of view, so that the operator can conveniently observe the guide 2, and on the other hand, the tube wall 30 is provided around the guide 2, so that the shielding of the front or surrounding tissues on the guide 2 is weakened, and the guide 2 can be kept in a visible state, so that the operator can conveniently judge the current state. Further, the tube enclosure wall 30 allows the guide 2 to be in a relatively stable state, and the operator can obtain clear image information to facilitate subsequent control. In practical use, it can be obviously observed that the image acquisition effect in the embodiment is better than that of the current two types, and the attached drawing is a static expression and is only a schematic illustration.

Further, referring to fig. 5A to 5D with emphasis, the tube front end portion 20 of the support tube 1 has a tube front end portion peripheral surface 21 and a tube front end portion end surface 22, the tube front end portion peripheral surface 21 is provided to extend rearward from the periphery of the tube front end portion end surface 22, and the mounting opening 101 and the working opening 201 are formed in the tube front end portion end surface 22. The tube front end face 22 of the support tube 1 comprises a working end face 221 and a mounting end face 222, and the working end face 221 and the mounting end face 222 are connected to each other. The working opening 201 is formed in the working end surface 221, and the mounting opening 101 is formed in the mounting end surface 222. The mounting end surface 222 extends forward along the working end surface 221.

The tube front end portion end surface 22 of the tube front end portion 20 of the support tube 1 on which the operation is formed may be an inclined arc surface inclined forward and inward from the circumferential side position of the support tube 1, that is, the mounting end surface 222. In other words, the working end surface 221 may form an obtuse angle with the forward extending direction of the axis of the tube front end 20 to facilitate the feeding of the tube front end surface 22 of the support tube 1.

The tube front end portion end surface 222 of the tube front end portion 20 of the support tube 1, on which the mounting opening 101 is formed, may be an arc surface and may be arranged substantially perpendicular to the axis of the tube front end portion 20. Since the mounting end face 222 is arranged forward with respect to the working end face 221, arranging the mounting end face 222 perpendicular with respect to the tube front end 20 facilitates providing a certain contact area at the front end of the support tube 1 to avoid that the front end of the support tube 1 is too sharp.

Preferably, the circumferential edge of the tube front end surface 22 of the tube front end 20 of the entire support tube 1 is provided in an arc shape.

Further, the support tube 1 includes a tube enclosure wall 30 and a tube partition wall 40, the tube partition wall 40 being provided to the tube enclosure wall 30 and partitioning at least a part of the installation passage 100 and at least a part of the working passage 200.

It is to be understood that the tube surrounding wall 30 and the tube dividing wall 40 form the tube structure body 10 and the tube front end portion 20 of the support tube 1, respectively, which does not mean that the tube structure body 10 and the tube front end portion 20 are integrated, and the tube structure body 10 and the tube front end portion 20 may be integrally formed, or the tube structure body 10 and the tube front end portion 20 may be separately disposed. In addition, the tube dividing wall 40 may extend integrally with the tube surrounding wall 30, or may be disposed separately from the tube surrounding wall 30, for example, the tube dividing wall 40 may be inserted into the tube surrounding wall 30. In addition, the tube partition wall 40 may be a dense sheet structure such that the working channel 200 and the installation channel 100 do not communicate with each other at the position of the tube structural body 10. Alternatively, the tube partition wall 40 may be a hollow structure so that the working channel 200 and the installation channel 100 can communicate with each other at the position of the tube structural body 10. Alternatively, the tube partition walls 40 may be arranged in segments at various positions of the tube surrounding wall 30 along the length direction of the tube surrounding wall 30,

the tube partition wall 40 is provided with at least two functions, firstly, the installation channel 100 and the working channel 200 can be separated to reduce the mutual interference between the image capturing member 3 and the guide member 2 respectively located in the working channel 200 and the installation channel 100, and secondly, the support tube 1 can realize the positioning of the guide member 2 to some extent by the tube partition wall 40 to facilitate the image capturing member 3 to capture the image about the guide member 2.

It is to be noted that the pipe surrounding wall 30 portion forming the mounting opening 101 is provided to project beyond the pipe partition wall 40 to communicate the mounting passage 100 and the working passage 200 laterally. With the guide 2 mounted to the mounting channel 100, at the mounting opening 101 position, the guide 2 is restricted by the projecting pipe surrounding wall 30 portion on the pipe surrounding wall 30 portion side and is not restricted by the pipe dividing wall 40 on the pipe dividing wall 40 side, so that the guide 2 can be tilted in advance toward the working channel 200 by a certain design of the pipe leading end portion 20.

In other words, in further embodiments of the invention, the end faces of the tube partition walls 40 of the support tube 1 may be arranged flush with the end faces of the tube enclosure walls 30. Whereas in the present embodiment the end face of the tube partition wall 40 of the support tube 1 is arranged lower than the end face of the tube surrounding wall 30, the guide 2 can be arranged obliquely in advance towards the working channel 200 with respect to the flush arrangement, so that the guide 2 comes closer to the working channel 200. In addition, the absence of the tube partition wall 40 at the position of the mounting port 101 reduces the obstruction of the image capturing member 3 located in the working channel 200 by the tube partition wall 40, which facilitates the image capturing member 3 to directly capture the image of the guide member 2 protruding from the mounting port 101.

Further, the end face of the tube partition wall 40 of the support tube 1 at the tube front end 20 may be provided with a recess to facilitate better positioning of the guide 2. During the mounting of the support tube 1, the position of the guide 2 is influenced by the support tube 1 and the surrounding tissue, which may lead to wobbling. Since the tube wall 30 is convexly disposed around the guide 2, the tube wall 30 can play a certain role of protection for the guide 2, so as to reduce the influence of the surrounding tissues on the guide 2, and reduce the shaking of the guide 2 in the visible range, thereby improving the visual effect.

The tube wall 30, which projects beyond and is arranged at least partially around the guide 2, acts like a "cap" for the guide 2, in order to facilitate the smooth insertion of the support tube 1 along the guide 2 during the insertion process.

Further, the tube partition wall 40 of the support tube 1 is recessed inward at one end face of the tube front end portion 20 to form a notch 400, which on the one hand communicates the working channel 200 and the installation channel 100 on the side, and on the other hand, by the notch 400, the guide 2 which is installed in the installation channel 100 and protrudes from the installation opening 101 can be captured by the image pickup member 3 located in the working channel 200 in advance. In other words, the guide 2 may not need to wait until the support tube 1 is fully extended to be captured by the image capturing member 3.

Further, the support kit 1000 further comprises a support tube connector 4, wherein the support tube connector 4 is adapted to be arranged at the support tube 1 and at the rear end of the support tube 1. The support tube connector 4 may be detachably connected to the support tube 1, or may be integrally formed with the support tube 1.

The support tube connector 4 comprises a main connector 41, an injection connector 42 and an installation connector 43, and a main connecting channel 410, an injection connecting channel 420 and an installation connecting channel 430, wherein the main connector 41 is formed with the main connecting channel 410, which is suitable for being communicated with the working channel 200 of the support tube 1, wherein the injection connector 42 is formed with the injection connecting channel 420, which is suitable for being communicated with the main connecting channel 410, so as to be communicated with the working channel 200 of the support tube 1, wherein the installation connector 43 is formed with the installation connecting channel 430, which is suitable for being communicated with the installation channel 100 of the support tube 1.

The main connection channel 410 is adapted to be passed through by the image capturing member 3 to extend to the portion of the working channel 200 of the tube front end portion 20 of the support tube 1. The injection connecting channel 420 is adapted to be injected with a fluid to transmit the fluid to the position of the working channel 200 of the tube front end portion 20 of the support tube 1, thereby providing a clear view environment for the image capturing member 3 in front of the image capturing member 3 when necessary. The mounting connection channel 430 is adapted to pass through the guide 2. When the support pipe 1 is inserted along the guide 2, the guide 2 enters along the installation passage 100 of the support pipe 1 into the installation connection passage 430 of the support pipe connector 4 along one end thereof, and may pass through from the installation connector 43 to be exposed to the outside.

Optionally, at the support tube connector 4 position, the injection flow connection channel 420 is connected to the main connection channel 410 and the installation connection channel 430 is independent of the main connection channel 410. In other words, the guide 2 and the image capturing member 3 may be independent of each other and do not interfere with each other at the position of the supporting tube connector 4.

After the support tube connector 4 is mounted to the support tube 1, the main connection passage 410 of the support tube connector 4 and the working passage 200 of the support tube 1 are coaxially arranged, and at least a portion of the mounting connection passage 430 of the support tube connector 4 and the mounting passage 100 of the support tube 1 may be coaxially arranged. The relative positions of the image capturing member 3 and the guide member 2 are consistent whether they are located at the position of the support tube 1 or the position of the support tube connector 4. For example, during operation, the tube can be advanced in such a way that the working channel 200 is located above the installation channel 100, in such a way that the image acquisition member 3 is located above the guide member 2, similarly to the tube being advanced in a manner that it overlaps the guide member 2, on the one hand facilitating tube advancement and on the other hand not interfering too much with the position of the guide member 2. Of course, it will be understood by those skilled in the art that the support kit 1000 may also be arranged such that the installation channel 100 is located above the working channel 200, and the positions of the installation connection channel 430 of the support tube connector 4 and the main connection channel 410 of the support tube connector 4 corresponding to the installation channel 100 and the working channel 200, respectively, may also be arranged interchangeably.

Optionally, the main connection channel 410 of the main connector 41 of the support tube connector 4 is located at the central axis of the main connector 41, and the working channel 200 of the support tube 1 is located at the central axis of the support tube 1. The central axis of the main joint 41 of the support pipe connector 4 and the central axis of the support pipe 1 are located on the same axis. When an operator operates the supporting kit 1000, because the image acquisition part 3 is arranged on the central axis of the supporting tube 1, the image acquired by the image acquisition part 3 is positioned in the visual center, and the visual perception and the operation perception can be consistent, so that the operation of the operator is facilitated.

It is understood that, for the support tube 1, the relative position relationship between the working channel 200 and the installation channel 100 may be other ways, for example, the working channel 200 and the installation channel 100 may be located on two sides of the central axis of the support tube 1, or the installation channel 100 may be located on the central axis of the support tube 1.

In addition, the working channel 200 of the support tube 1 may be completely independent from the installation channel 100, the cross section of the working channel 200 may be circular, elliptical, or triangular, and the shape of the working channel 200 may be arranged as desired. The cross-section of the mounting channel 100 may be circular, oval or triangular, and the shape of the mounting channel 100 may be arranged as desired.

The shape of the entire support tube 1 may be arranged as required, and in this embodiment, the cross section of the tube structure body 10 of the support tube 1 is arranged to be circular, the cross section of the tube front end portion 20 of the support tube 1 is arranged to be flat, and the installation channel 100 for installing the guide member 2 is nested in the working channel 200 for installing the image pickup member 3. The shape of the working channel 200 and the installation channel 100 may be regular or irregular, respectively. Alternatively, the working channel 200 and the installation channel 100 are each circular.

Further, the support kit 1000 includes an outer tube 5 and a negative pressure suction connector 6, wherein the outer tube 5 and the negative pressure suction connector 6 are respectively provided to the support tube 1. In detail, the outer tube 5 is mounted to the negative pressure suction connector 6, and the negative pressure suction connector 6 is mounted to the support tube 1. Most of the support tube 1 is located inside the outer tube 5 and the negative pressure suction connector 6, at least a part of the support tube 1 projects forward from the outer tube 5 to expose the tube front end portion 20 of the support tube 1, and the support tube connector 4 located at the rear end of the support tube 1 is exposed outside the negative pressure suction connector 6. In other words, the outer tube 5, the negative pressure suction connector 6, and the support tube connector 4 are arranged in this order to the support tube 1. In practical applications, the outer tube 5 is brought to a desired position by the support tube 1, and then the support tube 1 is pulled out, leaving the outer tube 5 in the body and providing an operation passage by the outer tube 5.

The outer tube 5 and the negative pressure suction connector 6 are detachably mounted to the support tube 1 so that the outer tube 5 and the negative pressure suction connector 6 can be used independently of the support tube 1. The outer tube 5 is detachably mounted to the negative pressure suction connector 6 so that the outer tube 5 can be used independently of the negative pressure suction connector 6. It will of course be appreciated by those skilled in the art that the outer tube 5 and the vacuum connector 6 may be integrally formed, for example integrally formed.

More specifically, the outer tube 5 includes an outer tube main body 51, the outer tube main body 51 having a front end and a rear end, and the front end of the outer tube main body 51 and the tube front end portion 20 of the support tube 1 are located on the same side. The outer tube 5 is formed with a first passage 510 penetrating from the front end to the rear end, and the support tube 1 is mounted to the first passage 510 of the outer tube 5. The outer tube main body 51 can be torn toward the circumferential side at the rear end position thereof to pull out the outer tube 5 without pulling out a medical instrument when the first passage 510 of the outer tube 5 is disposed with the medical instrument.

Further, the outer tube 5 may further include two grip heads 52, and the two grip heads 52 are disposed at the rear end of the outer tube main body 51. When the operator needs to pull out or tear the outer tube main body 51, the operator can grip the two gripping heads 52 arranged at the rear end of the outer tube main body 51 to apply force to the outer tube main body 51 conveniently.

Preferably, the holding head 52 is obliquely disposed on the outer tube main body 51, and the included angle formed by the holding head 52 and the outer tube main body 51 is oriented toward the front end of the outer tube 5, so as to facilitate the force application of the operator toward the rear end of the outer tube 5.

The vacuum suction connector 6 may include a vacuum suction connecting body 61, a suction control tube 62, and a grip ring 63, wherein the vacuum suction connecting body 61 has a front end and a rear end, and the front end of the vacuum suction connecting body 61 and the tube front end 20 of the support tube 1 are located on the same side. The connecting body 61 has a second passage 610 that extends from the front end to the rear end of the connecting body 61. The first passage 510 of the outer tube 5 is adapted to communicate with the second passage 610 of the negative pressure suction connector 6. The support tube 1 passes through the first passage 510 of the outer tube 5 and the second passage 610 of the negative pressure suction connector 6.

The suction control tube 62 and the grip ring 63 are respectively disposed on opposite sides of the negative pressure connecting body and the suction control tube 62 extends obliquely from the front end toward the rear end of the negative pressure suction connecting body 61. When the operator operates, the index finger can pass through the holding ring 63, the thumb can press the suction control tube 62, and other fingers can abut against the other side of the suction control tube 62, so that the thumb can conveniently move along the suction control tube 62 to control the strength of the negative pressure suction. Of course, it should be understood by those skilled in the art that the negative pressure suction connector 6 is only illustrated by way of example, and may be designed according to requirements to be ergonomic and convenient for an operator to operate.

Further, the suction control tube 62 of the negative pressure suction connector 6 is communicated with the second passage 610 of the negative pressure suction connecting body 61 so that an object is sucked to a negative pressure apparatus from the front end of the outer tube 5 through the first passage 510 of the outer tube 5, the second passage 610 of the negative pressure suction connector 6, and the suction control tube 62 in this order after the suction control tube 62 is connected to the negative pressure apparatus. The suction control tube 62 is provided with a through hole to communicate with the second passage 610 of the negative pressure suction connecting body 61. The operator can control the magnitude of the negative pressure suction force by closing or opening the channel, for example, the operator can control the magnitude of the negative pressure suction force by pressing the through hole with a thumb. It is understood that the manner of the negative pressure suction control is not limited to this, for example, a valve may be provided at the position of the suction control tube 62, and the control of the magnitude of the negative pressure suction force may be realized by adjusting the flow rate of the suction control tube 62 by rotating a button.

Further, referring to fig. 6A and 6B, another embodiment of the support tube according to the above preferred embodiment of the present invention is illustrated. In the present embodiment, the tube front end portion 20 is a separate component and is detachably attached to the tube structure main body 10. The tube front end 20 may be installed in alignment with the tube structure body 10 such that the installation channel 100 and the working channel 200 formed at the portion of the tube structure body 10 and the installation channel 100 and the working channel 200 formed at the portion of the tube front end 20 are aligned with each other. In the present embodiment, the tube front end portion 20 is screwed to the tube structure main body 20. It will be appreciated that the tube front end 20 may be attached to the tube structure body 10 by other means, such as snapping, gluing, etc.

Further, the operation of the support tube 1 can be roughly divided into the following three stages:

first, the expansion phase

Referring to fig. 7A to 7C, the support tube 1 is fed along the guide member 2, and at the same time, the direction of the support tube 1 is timely adjusted based on the image information collected by the image pickup member 3. It is understood that the image pickup member 3 is installed at the working channel 200 of the support tube 1 and may be restricted by the working port 201 of the support tube 1, so that the image pickup member 3 can pick up image information of the guide 2 and image information of the mounting port 101 of the support tube 1 and can display on the display 3000. During the process of feeding the support tube 1 along the guide member 2, if the image information about the environment near the mounting opening 101 of the support tube 1 collected by the image collecting member 3 is not clear, the field-of-view clearing process can be performed by injecting a sterile or aseptic fluid into the working channel 200 through the injection channel of the support tube connector 4.

After the support tube 1 is inserted into position, the support tube 1 with the support tube connector 4 can be removed, leaving the outer tube 5 in the body, and the negative pressure suction connector 6 is mounted to the outer tube 5 and located outside the body. In other words, the outer tube 5 and the negative pressure suction connector 6 are mounted at a desired position with the aid of the support tube 1, the guide 2, and the image pickup member 3. The space originally provided by the outer tube 5 and the negative pressure suction connector 6 for accommodating the support tube 1 can be used for accommodating other instruments, and the following steps can be specifically referred.

It is worth mentioning that, referring to fig. 7B again, since the pipe surrounding wall 30 forming the mounting opening 101 is arranged to be protruded, a structure similar to a wing is formed at both sides of the guide 2. This on the one hand protects the guide 2 and reduces the side-to-side shaking of the guide 2 so that the image capturing device 3 can capture a relatively stable image, and on the other hand, the protruding portion of the tube wall 30 is the foremost portion of the entire support tube 1 and is always visible, which is beneficial for the operator to enter the tube.

Second, negative pressure suction stage

Referring to fig. 7D to 7F, a surgical device 7, such as a holmium laser lithotripter device, is inserted to a desired position along the second passage 610 of the negative pressure suction connector 6 and the first passage 510 of the outer tube 5. The suction control tube 62 of the negative pressure suction connector 6 is adapted to be connected to a negative pressure device to generate negative pressure. The holmium laser lithotripsy device is provided with a perfusion channel to convey fluid inwards, and a channel is formed between the holmium laser lithotripsy device and the outer tube 5 to discharge the fluid, so that an injection-outflow cycle is formed, and the intrarenal pressure is favorably maintained at a reasonable level. The operator can control the size of the negative pressure suction force by controlling the suction control tube 62 to suck out the crushed stone in the body. After the surgery is over, say after the stones in the kidney that are desired to be treated have been cleared, the holmium laser lithotripsy device can be withdrawn. It is of course understood that the type of the surgical device 7 is not limited to the holmium laser lithotripsy device exemplified, and may be an endoscope, a therapeutic drug or other instruments that can be used for observation, manipulation and treatment.

Third, tail sweeping stage

Referring to FIGS. 7G to 7J, the negative pressure suction connector 6 is detached from the outer tube 5, and then an indwelling tube 8 is inserted from the first passage 510 along the outer tube 5, and the indwelling tube 8 is indwelling in the human body. Applying a force to both of the gripping heads 52 of the outer tube 5, the outer tube 5 can be torn toward both sides of the indwelling tube 8, and thus peeled off from the outer tube 5, thereby indwelling only the indwelling tube 8 in the human body.

It will be appreciated by persons skilled in the art that the embodiments of the invention described above and shown in the drawings are given by way of example only and are not limiting of the invention. The objects of the invention have been fully and effectively accomplished. The functional and structural principles of the present invention have been shown and described in the examples, and any variations or modifications of the embodiments of the present invention may be made without departing from the principles.
