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 sleeve and a system with an image capturing function.

Background

The medical staff can treat the patient outside the body, if the position to be treated is on the surface of the patient, the medical staff can directly apply the corresponding therapeutic appliance or the therapeutic drug on the surface of the patient, and if the position to be treated is in the patient, the medical staff can treat the target position in the patient by means of some professional appliances.

Further, if a medical practitioner desires to deliver a corresponding therapeutic device or therapeutic drug from outside the body to a target site in the body, the medical practitioner typically needs to travel a certain distance in the body to reach the desired site by means of a natural or artificial passageway. The natural channel is a channel formed by the natural body, and the medical staff can smoothly send the target object to the target position along the natural channel by operating the appliance. The artificial channel is a channel formed by the back of the body, and a medical staff can form a channel extending from the body surface to the body by operating an appliance such as a puncture needle. In order to reduce injury to the human body and also to reduce difficulty in establishing a passageway, the following operations are generally performed in order to establish a acquired passageway: a small-sized passage is created with the elongate member and then a support tube is placed along the elongate member or other guide member, the support tube having a cross-sectional dimension greater than the elongate member, so that a larger-sized working channel can be created for placement of a corresponding medical device.

There are many problems in such a way of establishing an operation channel at present, in which a blood vessel may be fully distributed around a small-sized channel which is established in advance, so that deviation occurs in the position where the support tube enters due to the fact that medical staff cannot observe the internal condition during the process of entering the support tube, for example, the depth of entering the support tube may be too deep, so that a specific instrument is inserted into a non-target position, the patient may bleed greatly due to the fact that the instrument is inserted into the blood vessel, or even the support tube itself breaks the blood vessel to bleed greatly, for example, the position where the support tube enters may be too shallow, so that related instruments or medicines cannot be sent to a proper position to perform the function.

One way to solve the above problems is to mark the support tube, and position the support tube during insertion by using a B-mode ultrasonic machine or other positioning device, so that the support tube is first installed to a correct position, and then a subsequent operation is performed by the installed support tube. The problem with this solution is that the medical staff has to resort to additional equipment for the placement of the support tube and in general such equipment is planar in position, i.e. the medical staff is able to know the general position of the support tube but still has to insert the support tube to an unintended position, for example into a peripheral blood vessel, resulting in massive bleeding.

The preferred embodiments in the following description are by way of example only and other obvious variations will occur to those skilled in the art. The basic principles of the invention defined in the following description may be applied to other embodiments, variations, modifications, equivalents, and other technical solutions without departing from the spirit and scope of the invention.

It will be appreciated by those skilled in the art that in the present disclosure, the terms "longitudinal," "transverse," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," etc. refer to an orientation or positional relationship based on that shown in the drawings, which is merely for convenience of description and to simplify the description, and do not indicate or imply that the apparatus or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore the above terms should not be construed as limiting the present invention.

It will be understood that the terms "a" and "an" should be interpreted as referring to "at least one" or "one or more," i.e., in one embodiment, the number of elements may be one, while in another embodiment, the number of elements may be plural, and the term "a" should not be interpreted as limiting the number.

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

The system with image capturing function includes the support kit 1000, an image processor 2000 and a display 3000, wherein the support kit 1000 includes the support tube 1 and may further include a guide 2 and an image capturing element 3, wherein the image processor 2000 processes to obtain an image based on information captured by the image capturing element 3 of the support kit 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 kit 1000 is communicatively coupled to the image processor 2000.

At least part of the support tube 1 piece can be fed into the body, for example a human or animal body, the guide 2 is adapted to be mounted to the support tube 1 of the support tube 1 piece to guide the support tube 1 to be mounted in a suitable position in the body, the image acquisition member 3 is adapted to be mounted to the support tube 1 of the support tube 1 piece to visualize the mounting process of the support tube 1 in acquiring environmental information of the surroundings of the support tube 1, in particular in the advancing direction of the support tube 1, so that the mounting of the support tube 1 is controllable.

In detail, the support tube 1 of the support tube 1 member includes a tube structure body 10 and has a tube front end portion 20, the tube front end portion 20 being disposed at one end of the tube structure body 10, respectively, wherein the support tube 1 has a mounting passage 100 and a working passage 200 and the mounting passage 100 and the working passage 200 are adapted to extend to the tube front end portion 20 at the tube structure body 10 and penetrate the tube structure body 10 and the tube front end portion 20, respectively.

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

The guide 2 is adapted to be inserted into the body to provide a guiding function for the support tube 1 later. There are many ways to insert the guide 2 into the body, for example, a relatively small slender and stiff elongate puncture member may be inserted into the body, then the guide 2 is inserted along the inside of the elongate puncture member, and the elongate puncture member is pulled out, leaving the guide 2 in the body, suitable for guiding the support tube 1 in place in the body. The guide 2 is an elongated member that primarily serves as a guide that can be pulled out directly after use and without damaging tissue in the body. The guide 2 may be made of various materials, such as a metal material, a plastic material, etc., which are illustrated herein without limitation.

The image capturing element 3 may comprise a connecting member 31 and an image capturing head end 32, the image capturing head end 32 being arranged at a front end of the connecting member 31 and being adapted to capture image information. A rear end of the connection member 31 may be connected to the image processor 2000 or an energy supply device, it will be understood that the image capturing element 3 may be an active device or a passive device, and the image capturing element 3 and the image processor 2000 may be connected by a wired or wireless method. The image acquisition head 32 may incorporate a light source and a light sensor to assist the light sensor in acquiring images. 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 comprise an electronic sensor, for example, the light sensor may be a camera, but is not limited to a camera module implemented as a lens and CMOS image sensor, and of course, may be any other type of sensor 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 acquisition member 3 may comprise a fiber optic sensor which may be a plurality of pixels formed by optical fibers.

The image pickup 3 is mounted in advance to the working channel 200 of the support tube 1 before the support tube 1 is inserted into the body. It is understood that the image capturing element 3 may be integrated in the working channel 200 of the support tube 1 in advance, or the image capturing element 3 may be detachably mounted to the working channel 200 of the support tube 1. When the support tube 1 needs to be mounted, the guide 2 is partially inserted along the mounting passage 100 of the tube front end portion 20 of the support tube 1 to be sent into the support tube 1 to a desired position along the guide 2 with the aid of the image pickup 3.

Further, the support pipe 1 has a mounting port 101 and a working port 201, the mounting port 101 forming the pipe front end portion 20 and communicating with the mounting passage 100, and the working port 201 being formed in the pipe front end portion 20 and communicating with the working passage 200. The guide 2 is adapted to protrude from the mounting opening 101 and continue to extend forward, the image acquisition head end 32 being adapted to be mounted in 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 acquisition head end 32 is securely mounted adjacent the working port 201 to stably acquire image information.

The mounting opening 101 and the working opening 201 are designed such that the image pickup 3 arranged in the working channel 200 can pick up appropriate image information to assist the support tube 1 in feeding the support tube 1 along the guide 2 on the premise that the image information of the guide 2 in the vicinity of the mounting opening 101 is observed.

Specifically, the mounting port 101 is provided so as to extend obliquely forward with respect to the working port 201. The extending direction from one end of the support pipe 1 toward the pipe front end portion 20 is forward. Since the mounting port 101 is arranged to extend obliquely forward, the guide 2 is mounted to the mounting port 101 with a limit in a certain range, the guide 2 passing out of the mounting port 101 is also allowed to extend obliquely forward under the limit of the mounting port 101.

After the image capturing element 3 is disposed on the support tube 1 and the guide 2 passes through the support tube 1, the guide 2 forms an angle with the optical axis of the image capturing element 3 on the axis of the portion of the tube front end 20 of the support tube 1. It will of course be understood that this does not mean that there is a junction between 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, for example that 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 working 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 working port 201, the position of the mounting port 101 located in front of the image pickup 3 can be picked up when the image pickup 3 is operated. In some other types of support pipes 1 currently used, the mounting port 101 and the working port 201 are arranged side by side or the mounting port 101 is arranged behind the working port 201, which makes it impossible for the image pickup 3 mounted on the mounting channel 100 to pick up an image of the position of the mounting port 101.

In more detail, with the mounting port 101 and the working port 201 arranged side by side, it is difficult for the image pickup member 3 to pick up image information of the mounting port 101 or the working port 201, and since the mounting 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 the support tube 1 entering the body. Further, the mounting port 101 and the working port 201 are arranged side by side, and the mounting port 101 and the working port 201 are located at the foremost end of the support tube 1, which is the site that first enters the unknown region in the body, whereas the image pickup member 3 cannot pick up the working port 201 or is the case of the mounting port 101, the image information picked up by the image pickup member 3 arranged forward is the environmental information in front of the tube front end portion 20 of the support tube 1, so that the image information picked up by the image pickup member 3 may not prevent this in advance even if the tube front end portion 20 penetrates into the blood vessel around the guide member 2 during the advancing of the support tube 1 because the mounting port 101 and the working port 201 are in a blind area for the image pickup member 3 at this time.

In the case where the working port 201 is disposed in front of the mounting port 101, the image pickup 3 mainly picks up an image of the front of the tube front end portion 20 of the support tube 1. In detail, the working port 201 and the mounting port 101 are disposed at the pipe front end portion 20 and are disposed forward, the working port 201 is located in front of the mounting port 101, and the working port 201 corresponds to a frontmost position located throughout the support pipe 1. Similarly, since the image pickup member 3 is mounted to the mounting passage 100 and may be at least partially located at the mounting port 101 to pick up an image forward, the image pickup member 3 itself is hard to pick up the position of the mounting port 101 where it is located, and thus there is still a possibility that the portion of the tube front end portion 20 of the support tube 1 forming the mounting port 101 is inserted into an unintended position, although the support tube 1 is controllably advanced forward along the guide member 2 in the display of the display 3000 at this time, it is possible that the portion of the tube front end portion 20 of the support tube 1 forming the mounting port 101 has been inserted into a blood vessel in a visual blind area position.

In the present embodiment, however, by arranging the working port 201 at the rear of the mounting port 101 such that the foremost position of the support pipe 1 is the mounting port 101 position, and the image pickup 3 arranged at the mounting passage 100 can capture the image information of the mounting port 101 position forward to allow the operator to observe the condition of the mounting port 101 and the condition of the guide 2 protruding from the mounting port 101, the support pipe 1 can complete the entire mounting process with its foremost end controllable. In this way, the installation process of the support tube 1 truly achieves head end visualization and head end controllability, reduces the risk of the support tube 1 being inserted into an unexpected position during the installation process, and increases the safety of the entire intubation process.

Further, in the two present arrangements of the mounting port 101 and the working port 201 mentioned before, the mounting passage 100 and the working passage 200 are arranged in parallel, irrespective of the portions of the mounting passage 100 and the working passage 200 of the tube structural body 10 or the portions of the mounting passage 100 and the working passage 200 of the tube front end portion 20. This makes the optical axis center of the image pickup 3 mounted to the mounting passage 100 and the center axis of the guide 2 mounted to the working passage 200 parallel to each other. When the operator is installing the support pipe 1, the guide 2 observed through the display 3000 is not located at the visual center, which makes the operator difficult to operate, that is, the guide 2 is always located at the position of the display 3000 with the visual center being shifted down or up or left or right, and the operator needs to complete the installation of the support pipe 1 along the guide 2 that is offset in the visual sense.

In the present embodiment, however, 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 center of the optical axis 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 pipe 1, so as to facilitate the operation of the operator.

In detail, the installation passages 100 at the pipe front end portion 20 of the support pipe 1 are provided in an inclined arrangement, and are arranged obliquely toward the front toward the direction in which the working passage 200 is located. The guide 2 protruding from the mounting port 101 may be inclined under the constraint of the mounting channel 100 and/or the mounting port 101. It will be appreciated that the constraint on the orientation of the guide 2 may be achieved by the mounting channel 100 alone, by the mounting port 101 alone, or by a combination of the mounting channel 100 and the mounting port 101.

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

In the present embodiment, the mounting channel 100 at the tube front end 20 is arranged to be inclined toward the working channel 200, which is advantageous in downsizing the tube front end 20, on the one hand, to facilitate feeding the support tube 1 into the body, and on the other hand, to reduce the possibility of damage to the tissue in the body due to the support tube 1 being large in size relative to the originally 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 tube front end portion 20 position, 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 being disposed opposite to each other, the front end of the support tube 1 being located at the tube front end 20, the rear end of the support tube 1 being 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 mounting 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, two existing arrangements of the mounting port 101 and the working port 201 of the support pipe 1 are shown in fig. 8A and 8B, 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 is an arrangement of the mounting port 101 and the working port 201 of the support pipe 1 in the present embodiment, the mounting port 101 being arranged in front of the working port 201.

For the above three, it is apparent that the two support pipes 1 illustrated in fig. 8A and 8B have a severe shaking motion through the guide member 2 of the support pipe 1 during the pipe feeding process, and the guide member 2 is directly exposed, so that once being pressed by the front tissue, the guide member 2 may disappear in the field of view, which results in that the operator cannot judge the current situation.

Whereas in fig. 8C the support tube 1 is provided with a protruding tube enclosure wall 30 on the peripheral side of the guide 2, on the one hand the tube enclosure wall 30 is visible in the field of view, thereby facilitating the operator to observe the guide 2, and on the other hand the tube enclosure wall 30 is provided on the peripheral side of the guide 2, reducing the shielding of the guide 2 from the forward or surrounding tissue, so that the guide 2 can be kept in a visible state, facilitating the operator to determine the current state. Further, the tube 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 prior two types, and the attached drawings are static expression modes and are only schematic illustrations.

Still further, with emphasis on fig. 5A to 5D, the pipe front end portion 20 of the support pipe 1 has a pipe front end portion peripheral surface 21 and a pipe front end portion end surface 22, the pipe front end portion peripheral surface 21 is provided to extend rearward from the peripheral edge of the pipe front end portion end surface 22, and the mounting port 101 and the working port 201 are formed in the pipe front end portion end surface 22. The tube front end face 22 of the support tube 1 includes 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 port 201 is formed in the working end surface 221, and the mounting port 101 is formed in the mounting end surface 222. The mounting end surface 222 extends forward along the working end surface 221.

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

The mounting end face 222 of the tube front end face 22 of the tube front end 20 of the support tube 1, on which the mounting port 101 is formed, may be a cambered surface, and may be disposed substantially perpendicular to the axis of the tube front end 20. Since the mounting end surface 222 is arranged forward with respect to the working end surface 221, arranging the mounting end surface 222 perpendicularly with respect to the tube front end portion 20 is advantageous in 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 peripheral edge of the tube front end face 22 of the tube front end 20 of the entire support tube 1 is provided in an arc shape.

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

It will be appreciated that the pipe enclosing wall 30 and the pipe partition wall 40 form the pipe structural body 10 and the pipe front end portion 20 of the support pipe 1, respectively, which does not mean that the pipe structural body 10 and the pipe front end portion 20 are integral, and the pipe structural body 10 and the pipe front end portion 20 may be integrally formed, or that the pipe structural body 10 and the pipe front end portion 20 are separately arranged. In addition, the pipe dividing wall 40 may be integrally extended from the pipe enclosing wall 30, or may be separately disposed from the pipe enclosing wall 30, for example, the pipe dividing wall 40 may be inserted into the pipe enclosing wall 30. In addition, the pipe partition wall 40 may be a compact sheet structure so that the working channel 200 and the installation channel 100 do not communicate with each other at the position of the pipe structural body 10. Alternatively, the pipe dividing wall 40 may have a hollow structure so that the working channel 200 and the installation channel 100 may communicate with each other at the position of the pipe structural body 10. Alternatively, the tube dividing wall 40 may be arranged in segments at various locations along the length of the tube enclosure wall 30 at the tube enclosure wall 30,

The provision of the tube partition wall 40 serves at least two functions, firstly, to separate the installation channel 100 and the working channel 200 so as to reduce the interference between the image capturing element 3 and the guide element 2 respectively located in the working channel 200 and the installation channel 100, and secondly, by means of the tube partition wall 40, the support tube 1 can achieve a positioning of the guide element 2 to a certain extent so as to facilitate the capturing of images with respect to the guide element 2 by the image capturing element 3.

Notably, the pipe surrounding wall 30 portion forming the mounting port 101 is provided to protrude from the pipe partition wall 40 to laterally communicate the mounting passage 100 and the working passage 200. With the guide 2 mounted to the mounting passage 100, the guide 2 is restricted by the protruding tube surrounding wall 30 portion on the tube surrounding wall 30 portion side and is not restricted by the tube dividing wall 40 on the tube dividing wall 40 side at the mounting port 101 position, so that the guide 2 can be inclined toward the working passage 200 in advance by a certain design of the tube front end portion 20.

In other words, in other embodiments of the invention, the end face of the tube partition wall 40 of the support tube 1 may be arranged flush with the end face of the tube enclosure wall 30. Whereas in the present embodiment, the end face of the pipe partition wall 40 of the support pipe 1 is arranged lower than the end face of the pipe surrounding wall 30, the guide 2 may be arranged obliquely toward the working channel 200 in advance with respect to the flush arrangement so that the guide 2 is closer to the working channel 200. In addition, due to the absence of the tube partition wall 40 at the mounting port 101, the obstruction of the tube partition wall 40 to the image pickup member 3 located in the working channel 200 is weakened, facilitating the image pickup member 3 to directly pick up the image of the guide member 2 protruding from the mounting port 101.

Further, the tube partition wall 40 of the support tube 1 may be provided recessed at the end face of the tube front end portion 20 to facilitate better positioning of the guide 2. During the installation of the support tube 1, the guide 2 may be subjected to vibrations in its position due to the compression of the support tube 1 and surrounding tissue. Since the tube surrounding wall 30 is convexly disposed on the peripheral side of the guide 2, the tube dividing wall 40 is removed, so that the tube surrounding wall 30 can play a certain protective role for the guide 2 to reduce the influence of surrounding tissues on the guide 2, and reduce the shaking of the guide 2 in the visual range to facilitate the improvement of visual effect.

The portion of the tube enclosing wall 30 that protrudes and is at least partially arranged around the guide 2 is similar to a shielding effect of a "cap rim" for the guide 2, so as to facilitate the support tube 1 being fed smoothly along the guide 2 during the pushing-in process.

Further, the pipe partition wall 40 of the support pipe 1 is recessed inward at one end face of the pipe front end portion 20 to form a notch 400, which communicates the working channel 200 and the installation channel 100 laterally on the one hand, and by which notch 400, on the other hand, the guide 2 installed in the installation channel 100 and protruding from the installation port 101 can be captured in advance by the image pickup 3 located in the working channel 200. In other words, the guide 2 may not need to wait until it is fully extended out of the support tube 1 to be captured by the image pickup 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 pipe connector 4 may be detachably connected to the support pipe 1, or may be integrally formed with the support pipe 1.

The support pipe connector 4 comprises a main connection head 41, a flow connection head 42 and a mounting connection head 43 and has a main connection channel 410, a flow connection channel 420 and a mounting connection channel 430, respectively, wherein the main connection head 41 is formed with the main connection channel 410 adapted to communicate with the working channel 200 of the support pipe 1, wherein the flow connection head 42 is formed with the flow connection channel 420 adapted to communicate with the main connection channel 410 to communicate with the working channel 200 of the support pipe 1, wherein the mounting connection head 43 is formed with the mounting connection channel 430 adapted to communicate with the mounting channel 100 of the support pipe 1.

The main connection passage 410 is adapted to pass through the image pickup 3 to extend to the working passage 200 portion of the tube front end portion 20 of the support tube 1. The flow connection channel 420 is adapted to be filled with fluid to transfer fluid to the working channel 200 position of the tube front end 20 of the support tube 1, thereby enabling a clearer view of the image capturing member 3 in front of the image capturing member 3 when needed. The mounting connection channel 430 is adapted to be passed through by the guide 2. When the support pipe 1 is inserted along the guide 2, one end along which the guide 2 is inserted along the mounting passage 100 of the support pipe 1 enters the mounting connection passage 430 of the support pipe connector 4, and may pass from the mounting connector 43 to be exposed.

Alternatively, at the support tube connector 4 position, the flow connection passage 420 is communicated with the main connection passage 410, and the mounting connection passage 430 is independent of the main connection passage 410. In other words, the guide 2 and the image acquisition member 3 can be independent of each other and do not interfere with each other at the support tube connector 4 location.

After the support pipe connector 4 is mounted to the support pipe 1, the main connection passage 410 of the support pipe connector 4 and the working passage 200 of the support pipe 1 are coaxially arranged, and at least part of the mounting connection passage 430 of the support pipe connector 4 and the mounting passage 100 of the support pipe 1 may be coaxially arranged. The relative positions of the image acquisition member 3 and the guide member 2 are consistent whether they are in the position of the support tube 1 or the position of the support tube connector 4. For example, during operation, the tube may be advanced in such a way that the working channel 200 is located above the mounting channel 100, in such a way that the image acquisition member 3 is located above the guide member 2, similar to advancing the tube in such a way that it is carried over the guide member 2, on the one hand, and on the other hand, without excessive interference with the position of the guide member 2. Of course, it will be appreciated by those skilled in the art that the support kit 1000 may also be arranged such that the mounting channel 100 is located above the working channel 200, and the positions of the mounting connection channel 430 of the support tube connector 4 and the main connection channel 410 of the support tube connector 4 of the working channel 200, respectively, corresponding to the mounting channel 100 may also be interchanged.

Alternatively, the main connection passage 410 of the main joint 41 of the support pipe connector 4 is located at the central axis of the main joint 41, and the working passage 200 of the support pipe 1 is located at the central axis of the support pipe 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 support kit 1000, since the image acquisition member 3 is disposed at the central axis of the support tube 1, the image acquired by the image acquisition member 3 is located at the visual center, and the visual perception and the operation perception thereof can be consistent, so as to facilitate the operation of the operator.

It will be understood that, for the support pipe 1, the relative positional relationship between the working channel 200 and the mounting channel 100 may be other manners, for example, the working channel 200 and the mounting channel 100 may be located on two sides of the central axis of the support pipe 1, or the mounting channel 100 may be located on the central axis of the support pipe 1.

In addition, the working channel 200 of the support pipe 1 may be completely independent of the installation channel 100, the working channel 200 may be circular, oval, or triangular in cross section, and the shape of the working channel 200 may be arranged according to the need. 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 according to the need.

The shape of the entire support tube 1 may be arranged as required, and in this embodiment, the cross section of the tube structural body 10 of the support tube 1 is arranged in a circular shape, the cross section of the tube front end portion 20 of the support tube 1 is arranged in a flat shape, and the mounting passage 100 for mounting the guide 2 is stacked on the working passage 200 for mounting the image pickup 3. The shape of the working channel 200 and the mounting channel 100 may be regular or irregular, respectively. Optionally, the working channel 200 and the mounting channel 100 are each circular.

Further, the support kit 1000 comprises 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 arranged at the support tube 1. Specifically, the outer tube 5 is attached to the negative pressure suction connector 6, and the negative pressure suction connector 6 is attached to the support tube 1. A majority 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 protrudes forward from the outer tube 5 to expose the tube front end 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 sequentially arranged to the support tube 1. In the practical process, the outer tube 5 is brought to the expected position by the support tube 1, then the support tube 1 is pulled out, the outer tube 5 is left in the body and an operation channel is provided 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 a person skilled in the art that the outer tube 5 and the negative pressure connector 6 may be provided integrally, for example, in one piece.

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, the front end of the outer tube main body 51 being located on the same side as the tube front end portion 20 of the support tube 1. 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 the medical instrument when the first passage 510 of the outer tube 5 is arranged with the medical instrument.

Further, the outer tube 5 may further include two grip heads 52, and the two grip heads 52 are provided at the rear end of the outer tube main body 51. When an operator needs to pull out or tear the outer tube body 51, the two gripping heads 52 provided at the rear end of the outer tube body 51 may be gripped to facilitate application of a force to the outer tube body 51.

Preferably, the grip head 52 is disposed obliquely to the outer tube main body 51, and a direction of an included angle formed by the grip head 52 and the outer tube main body 51 is directed toward the front end of the outer tube 5, so as to facilitate an operator to apply a force toward the rear end of the outer tube 5.

The negative pressure suction connector 6 may include a negative pressure suction connection body 61, a suction control tube 62, and a grip ring 63, wherein the negative pressure suction connection body 61 has a front end and a rear end, and the front end of the negative pressure suction connection body 61 and the tube front end portion 20 of the support tube 1 are located on the same side. The negative pressure suction connection body 61 has a second passage 610 penetrating from the front end to the rear end of the negative pressure suction connection body 61. The first channel 510 of the outer tube 5 is adapted to communicate with the second channel 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 pipe 62 and the grip ring 63 are respectively arranged at opposite sides of the negative pressure connection body and the suction control pipe 62 extends obliquely from the front end toward the rear end of the negative pressure suction connection body 61. When an 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 lean 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 suction force of negative pressure. Of course, it will be appreciated by those skilled in the art that the negative pressure suction connector 6 may be designed to be ergonomic as desired for convenient operator handling, by way of example only.

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 connection body 61, so that after the suction control tube 62 is connected to a negative pressure apparatus, an object is sucked to the 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. The suction control tube 62 is provided to the second passage 610 having a through hole to communicate with the negative pressure suction connection body 61. The operator can control the magnitude of the negative pressure attractive force in a way that the passage is closed or the through hole is opened, for example, the operator can control the magnitude of the negative pressure attractive force in a way that the operator presses the through hole with the thumb. It should be understood that the manner of 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 magnitude of the flow rate of the suction control tube 62 may be adjusted by rotating a button to control the magnitude of the negative pressure suction force.

Further, referring to fig. 6A and 6B, another implementation 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 member, and is detachably attached to the tube structural body 10. The pipe front end portion 20 may be installed in alignment with the pipe structural body 10 such that the installation channel 100 and the working channel 200 formed at the pipe structural body 10 portion and the installation channel 100 and the working channel 200 formed at the pipe front end portion 20 portion are aligned with each other. In the present embodiment, the pipe front end portion 20 is screwed to the pipe structural 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 snap fit, adhesive, etc.

Further, the operation of the support tube 1 may be approximately three phases, respectively:

First, the expansion phase

Referring to fig. 7A to 7C, the support tube 1 is fed along the guide 2, and at the same time, the direction of the support tube 1 is adjusted in time based on the image information collected by the image pickup 3. It will be appreciated that the image capturing member 3 is mounted to the working channel 200 of the support tube 1 and may be constrained by the working port 201 of the support tube 1 such that the image capturing member 3 can capture image information of the guide member 2 and image information of the mounting port 101 of the support tube 1 and may be displayed on the display 3000. During the feeding of the support tube 1 along the guide 2, if it is found that the image information acquired by the image acquisition member 3 about the environment around the mounting port 101 of the support tube 1 is not clear, a field-of-view clarification process may be performed by injecting a sterile or sterilized fluid into the injection passage of the support tube connector 4 toward the working passage 200.

After the support tube 1 is inserted into place, 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 desired positions with the aid of the support tube 1, the guide 2 and the image pickup 3. The space for accommodating the support tube 1 provided by the outer tube 5 and the suction connector 6 is available for accommodating other instruments, and reference is made to the following steps.

It is worth mentioning that, with emphasis on fig. 7B, since the tube enclosure wall 30 forming the mounting port 101 is convexly arranged, wing-like structures are formed on both sides of the guide 2. This on the one hand protects the guide 2 and reduces the rocking of the guide 2 so that the image capturing member 3 can capture a relatively stable image, and on the other hand the part of the tube enclosing wall 30 which is arranged in a protruding manner is the foremost end of the whole support tube 1, which is always in a visible state, facilitating 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 lithotripsy device, is inserted along the second channel 610 of the suction connector 6 and the first channel 510 of the outer tube 5 to a desired location. 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 lithotripter is provided with a perfusion channel for delivering fluid inwards, and a channel is formed between the holmium laser lithotripter and the outer tube 5 for discharging fluid, thereby forming an injection-outflow cycle to facilitate maintaining the intra-renal pressure at a reasonable level. The operator can control the magnitude of the negative pressure suction force by controlling the suction control tube 62 to suck out the crushed stone in the body. The holmium laser lithotripsy device may be withdrawn after the procedure has ended, for example after the stones intended for treatment within the kidney have been cleaned. It will of course be appreciated that the type of surgical device 7 is not limited to the holmium laser lithotripsy device illustrated, but may be an endoscope, a therapeutic drug or other instrument useful for viewing, manipulation, or treatment.

Third, the tail sweeping stage

Referring to fig. 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 channel 510 along the outer tube 5, the indwelling tube 8 being indwelled in the human body. The outer tube 5 may be torn toward both sides of the indwelling tube 8 by applying a force to the two gripping heads 52 of the outer tube 5, thereby being peeled off from the outer tube 5, thereby leaving 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 by way of example only and are not limiting. The objects of the present invention have been fully and effectively achieved. The functional and structural principles of the present invention have been shown and described in the examples and embodiments of the invention may be modified or practiced without departing from the principles described.
