Fig. 1 and 2 illustrate schematic structural views of a surgical accessory 1000 according to some embodiments of the present disclosure at different angles, fig. 3 illustrates a top view of the surgical accessory 1000 according to some embodiments of the present disclosure, and fig. 4 illustrates a schematic structural view of a distal port 120 of the surgical accessory 1000 according to some embodiments of the present disclosure. As shown in fig. 1-4, surgical accessory 1000 can include a housing 100, a plurality of cannulas 200, and at least one cleaning tube 300.

The housing 100 may include a proximal port 110 and a distal port 120, the proximal port 110 being flared and the distal port 120 being flat in a straight shape. The plurality of cannulas 200 (e.g., cannulas 200a, 200b, 200c, collectively referred to as cannulas 200) may include an inner section 210 and an outer section 220 in communication with each other, the outer section 220 being located outside of the housing 100 and in communication with the proximal port 110 of the housing 100, the inner section 210 being located within the housing 100 and in communication with the distal port 120 of the housing 100. It will be appreciated that in some embodiments, the inner section 210 may be part of the housing 100, for example, the interior of the housing 100 may form the inner section 210, or the inner section 210 may be integrally formed with the housing 100, the inner section 210 communicating with the outer section 220. By designing distal port 120 to be flat, surgical attachment 1000 may be better suited for use in pulmonary surgery. The existing circular sheath tube cannot smoothly enter the body cavity through the ribs due to the large diameter, or can enter the body cavity after rib removal operation, so that large wounds are caused. The flat structure can conveniently enter the body cavity through the rib clearance, so that the large trauma to the human body is avoided.

The plurality of cannulas 200 may be comprised of an endoscope cannula and two surgical tool cannulas, with the interior sections 210 of the plurality of cannulas 200 being aligned in a straight line along the length of the straight flat at the distal port 120. Multiple cannulas 200 may be spaced apart lengthwise for passage of different surgical tools or endoscopes.

At least one cleaning tube 300 (e.g., cleaning tube 300a, cleaning tube 300b, collectively cleaning tubes 300) may extend from outside the housing 100 in a direction from the proximal port 110 to the distal port 120. It should be appreciated that the cleaning tube 300 may include an internal cleaning tube located within the housing 100. The inner cleaning tube may extend from the proximal port 110 to the distal port 120 of the housing 100. The cleaning tube 300 may also include an external cleaning tube located outside the housing 100, in communication with the internal cleaning tube, extending outwardly from the proximal end of the housing 100 for connection to an external cleaning source (e.g., water pump, air pump, etc.). It should be appreciated that the cleaning tube 300 may include only an inner cleaning tube, which may include a connection fitting at the proximal port 110 for connection to an external source of cleaning. The cleaning tube 300 may also include a nozzle at the distal end of the inner cleaning tube. As shown in FIG. 4, the nozzle may protrude from the end face of the distal port 120 to facilitate cleaning of the surgical instrument. The nozzles may be disposed in the interstices of the distal ports 120 of the plurality of inner sections 210.

In some embodiments, as shown in fig. 2 and 4, at least one cleaning tube 300 may include a first cleaning tube 300a and a second cleaning tube 300b on one side of the distal port 120, the first cleaning tube 300a may be used to transport a liquid, and the second cleaning tube 300b may be used to transport a gas. It should be appreciated that the first cleaning tube 300a may also be used to transport gas and the second cleaning tube 300b used to transport liquid. As shown in fig. 2 and 4, the first cleaning tube 300a and the second cleaning tube 300b may be spaced apart from each other at one side of the distal port 120 in the width direction of the flat shape. In some embodiments, the diameter of the cleaning tube 300 may be smaller than the diameter of the inner section 210. By delivering the liquid, the surgical instrument, such as an endoscope lens, is flushed clean. Residual liquid on the endoscope head is removed by delivering gas. Through setting up the cleaning tube, can clean endoscope or operation instrument fast in the art, guarantee the clear or operation instrument cleanness of operation field of vision, avoid pulling out the body cavity with endoscope or operation instrument and clean, show the shortened operation time.

In some embodiments, the radial dimension of proximal port 110 may be greater than the radial dimension (e.g., cross-sectional length) of distal port 120, and the radial dimension of housing 100 decreases in the direction of proximal port 110 toward distal port 120. Proximal port 110 is sized larger than distal port 120 to facilitate placement of outer sections 220 of the plurality of cannulas 200 to facilitate access of the plurality of surgical instruments from the plurality of cannulas 200, respectively, without interference from one another. The distal port 120 is smaller in size to ensure that it extends from a smaller incision into the interior of the body, reducing trauma.

In some embodiments, the inner sections 210 of the plurality of cannulae 200 are drawn toward one another in the direction of the proximal port 110 to the distal port 120. The outer sections 220 of the plurality of sleeves 200 extend outwardly away from one another. In this way, interference collisions between multiple surgical instruments passing through multiple cannulas 200 may be better avoided. It should be appreciated that the portions of the interior sections 210 of the plurality of cannulae 200 located proximate to the proximal port 110 may be proximate to one another in the direction of the proximal port 110 to the distal port 120 and the portions located proximate to the distal port 120 may be juxtaposed to one another.

In some embodiments, as shown in fig. 1, the plurality of cannulas 200 may include a first cannula 200a, a second cannula 200b, and a third cannula 200c. The inner sections 210 of the first 200a, second 200b and third 200c cannulas are arranged side-by-side along the length of the in-line flattened shape at the distal port 120. As shown in fig. 1, the third sleeve 200c may be an endoscope sleeve extending axially from a proximal end to a distal end, and the first sleeve 200a and the second sleeve 200b may be two surgical tool sleeves located on either side of the third sleeve 200c and extending proximally away from each other.

In some embodiments, the lengths of the plurality of cannulae 200 may be different. As shown in FIG. 1, the length of cannula 200c may be less than the length of cannula 200a and cannula 200b to facilitate insertion of a surgical instrument (e.g., an endoscope) through cannula 200c and into a surgical site. The lengths of the sleeve 200a and the sleeve 200b may be the same. It should be understood that the lengths of the cannulas 200a-c may also be the same, or portions of the cannulas 200 therein may be the same. The diameters of the plurality of cannulas 200 may also be varied, and may be specifically adjusted according to the size of the endoscope and surgical tool.

In some embodiments, at least a portion of the outer section 220 of the cannula 200a and the cannula 200b can be deformed (e.g., bent, telescoped, etc.) in a radial or axial direction of the outer section 220. Because the cannula 200 is capable of being deformed radially and/or axially, the passage of the surgical instrument through the cannula 200 is facilitated, and the pulling of the surgical instrument through the incision during passage through the cannula 200 is reduced, such that the distal end of the surgical instrument can still pass through the cannula 200 and the housing 100 more smoothly into the intended surgical site with a certain positioning error or offset.

In some embodiments, at least a portion of the outer section 220 of the sleeve 200a and 200b is made of a flexible material, which may allow the outer section 220 to deform. It should be appreciated that in any of the embodiments of the present disclosure, the flexible material may employ a thermoplastic elastomer (e.g., thermoplastic polyurethane, etc.), silicone rubber, or rubber, etc. The inflexible material may include plastics (e.g., polycarbonate, polypropylene, etc.), metallic materials, and the like. For example, the outer section 220 may be made of a flexible material in one portion and a non-flexible material in another portion. It should be appreciated that the outer section 220 may be made of a flexible material and the inner section 210 may be made of a non-flexible material. In some embodiments, the inner section 210 may also be made in part of a flexible material and in part of a non-flexible material. The portion of the inner section 210 extending toward the distal port 120 is made of a non-flexible material to ensure neutral communication between one end of the cannula 200 and the distal port 120 of the housing 100. For example, the outer sections of the sleeve 200a and 200b may be made of a flexible material, deformable, while the outer section of the sleeve 200c is made of a non-flexible material, non-deformable.

In some embodiments, the outer sections 220 of the plurality of cannulae 200 may include telescoping tubes 400, as shown in fig. 2 and 3. The telescoping tube 400 is capable of telescoping movement in the axial direction of the outer section 220 to provide for deformation of the outer section 220 in the axial direction, increasing the flexibility of the sleeve 200 in the axial direction.

Fig. 5A illustrates a partial cross-sectional structural schematic view of a surgical accessory 1000 according to some embodiments of the present disclosure, and fig. 5B illustrates a partial cross-sectional structural schematic view of a telescoping tube 400 of a surgical accessory 1000 according to some embodiments of the present disclosure. In some embodiments, as shown in fig. 5A and 5B, the telescoping tube 400 is tubular and may include an upper tube 410 and a lower tube 420 that are relatively slidable along the axial direction of the outer section 220. The upper pipe member 410 and the lower pipe member 420 may have different diameters, and the upper pipe member 410 and the lower pipe member 420 are movably sleeved together to realize axial expansion and contraction of the expansion pipe member 400. It should be appreciated that the telescoping tube 400 may be placed in communication at any location on the outer section 220 of the cannula 200. For example, as shown in fig. 5A and 5B, a telescoping tube 400 may be disposed at the proximal end of the outer section 220. The diameter of the upper pipe member 410 is greater than the diameter of the upper end portion of the lower pipe member 420 so that the upper pipe member 410 can be movably sleeved on the upper end portion of the lower pipe member 420 to realize the relative sliding of the upper pipe member 410 and the lower pipe member along the axial direction of the outer section 220. In some embodiments, a back-off (not shown) may be provided on upper tube 410 and/or lower tube 420 to prevent upper tube 410 and lower tube 420 from slipping during relative sliding.

In some embodiments, as shown in fig. 5A and 5B, the lower end portion of the lower tubular member 420 may include a radially outwardly extending projection 421, the projection 421 having a diameter greater than the diameter of the other portions of the lower tubular member 420. It will be appreciated that although fig. 2-5B illustrate the projection 421 as being provided on the lower tubular member 420, the projection 421 may be provided at other locations on the outer section. In some embodiments, the protruding portion 421 of the lower tubular member 420 may include a lumen in which a seal 422 may be disposed, the seal 422 having a slit for passage of a surgical instrument. The seal 422 allows for a sealed condition within the cannula 200 to be maintained as the surgical instrument is moved through the cannula 200 and relative to the cannula 200 to meet the surgical procedure requirements.

In some embodiments, as shown in fig. 2 and 3, surgical accessory 1000 can further include at least one connection device 500. Attachment means 500 may be provided on the housing 100 and/or the cannula 200, the attachment means 500 being used to attach a robotic arm or a surgical instrument clamped to the robotic arm to the surgical accessory 1000. In some embodiments, as shown in fig. 2 and 3, the connection device 500 may include a protrusion for mating with a clamp mounted on the robotic arm. In some embodiments, the connection device 500 may further include clamps, snap-in structures, adhesive structures, plug-in structures, snap-in structures, and the like. The mechanical arm may include structure thereon that mates with the attachment 500. The connection device 500 may be disposed on the cannula 200 (e.g., on the outer section 220), and the connection device 500 may be detachably and fixedly connected to the robot arm such that a surgical instrument disposed on the robot arm may smoothly pass through the cannula 200 at a predetermined angle and be movable along the cannula 200.

In some embodiments, the connection device 500 may also be disposed on the telescoping tube 400 (e.g., the upper tube 410), and the connection device 500 may be capable of telescoping movement along with the telescoping tube 400 in the axial direction of the sleeve 200, such that the positional flexibility of the connection device 500 on the sleeve 200 may be improved to facilitate connection of the connection device 500 with a robotic arm. It should be appreciated that the connection means 500 may also be provided on the lower tubular member 420 of the telescopic tube 400, or that part of the upper connection means 500 of the sleeve 200 is provided on the upper tubular member 410 of the telescopic tube 400, and another part of the connection means 500 is provided on the lower tubular member 420 of the telescopic tube 400. The above is merely an example, and is not limited thereto.
