The closure head 4 is arranged at the distal end 5 of the sheath 3, for example by snapping, or gluing or other connection. The middle part of the end socket 4 is provided with an opening 12 corresponding to the main cavity 10, and the edge of the opening 12 forms a stop for the edge of the cavity mirror so as to axially position the cavity mirror. The end socket 4 has a deflection function, and the direction of the fluid can be limited to the direction towards the opening 12 at the far end 5, so that the fluid forms an air curtain or a liquid curtain at the far end 5 to achieve the effect of protecting and cleaning the lens of the endoscope.
The connector 2 is provided with a fluid inlet 13, one end of the fluid inlet 13 is connected with a gas source or a liquid source, and the other end is connected with the auxiliary cavity 11 in a fluid mode, so that fluid can be introduced into the auxiliary cavity 11.
Therefore, the endoscope system 100 and the multi-cavity pipeline structure 1 are provided with a plurality of auxiliary cavities 11 at the periphery of a main cavity 10 through a double-layer structure provided with an inner wall 7 and an outer wall 8, fluid is injected into the plurality of auxiliary cavities 11 from a fluid access port 13 during the operation process, flows along the plurality of auxiliary cavities 11, flows out from a far end 5, deflects in the direction limited by a seal head 4, flows to an opening 12 corresponding to the main cavity 10, and flows in parallel or obliquely in front of a lens of an endoscope inserted into the main cavity 10, so that an air curtain or a liquid curtain can be formed in front of the lens through continuous injection of the fluid to form a barrier to the lens of the endoscope, so that the liquid or tissue fragments and the like close to the lens deflect in the direction and play a cleaning role to the lens of the endoscope, the coagulation of internal water vapor on the surface of the lens of the endoscope and the contamination of the liquid or tissue fragments and the like to the lens can be prevented during the operation process, thereby reducing or preventing the blurring and the loss of the operation visual field, the operation is ensured to be continuously performed under a clear visual field without taking the endoscope out of the body cavity midway for cleaning, so that the operation of a doctor can be avoided being interrupted, and the operation time of a patient is reduced; because the fluid flows in the auxiliary cavity 11 between the inner wall 7 and the outer wall 8, the flow of the fluid can be ensured to meet the requirement by designing the size of the auxiliary cavity 11, and a small gap can be arranged between the main cavity 10 and the cavity mirror, so that the cavity mirror is easy to insert and cannot generate large radial shaking; the end socket 4 can simultaneously realize the axial positioning of the cavity mirror and the deflection direction of the fluid, and has simple structure and low processing and manufacturing cost.
With continued reference to fig. 1, the sheath 3 further comprises a proximal end 6 opposite the distal end 5, i.e. the end closer to the operator during surgery, an inner wall 7, an outer wall 8 and a plurality of separation walls 9 extending from the distal end 5 to the proximal end 6, i.e. a secondary lumen 11 extending from the distal end 5 to the proximal end 6. Therefore, the structure can be simplified, and the processing and the manufacturing are convenient.
The connector 2 is connected to the proximal end 6, for example by snapping, or gluing or other connection, the fluid access 13 communicates with a portion of the plurality of sub-chambers 11, for example the fluid access 13 communicates with one or both of the sub-chambers 11, and the sides of the plurality of sub-chambers 11 corresponding to the proximal end 6 communicate with each other, for example by partially cutting away the outer wall 8, or partially opening the partition wall 9, etc., and fluid flows from the portion of sub-chambers 11 to the remaining sub-chambers 11 and along each sub-chamber 11 from the proximal end 6 to the distal end 5. The fitting 2 is provided with a seal assembly 14 on the front side of the fluid inlet 13 (the left side of the fluid inlet 13 in the orientation of fig. 1) to prevent fluid from flowing out of the fitting 2 from that side.
Therefore, among the plurality of auxiliary chambers 11, the flow velocity of the fluid in the auxiliary chamber 11 close to the fluid inlet 13 is high, and the flow velocity of the fluid in the auxiliary chamber 11 far from the fluid inlet 13 is low, so that a gas or liquid vortex is formed at the opening 12 due to circumferentially uneven flow velocity, and the direction of deflection of the liquid or tissue fragments and the like close to the lens of the endoscope can be more effectively made, and the lens is protected from being disturbed by water vapor, liquid or tissue fragments and the like in the internal environment.
In the description of the present invention, it is to be noted that the spatial relationship words are intended only for convenience of description, and may encompass other orientations of the elements in addition to the orientation depicted in the figures. For example, if an element is turned over, elements described as "front," "front," or "front" of other elements or features may be oriented "rear" of the other elements or features, or turned over at a particular angle, may be oriented "left," "lower left," "right," etc. of the other elements or features.
In other embodiments, the inner wall 7 or/and the plurality of partition walls 9 may also extend from the distal end 5 to a position in the middle of the sheath 3 without extending to the proximal end 6, i.e. the length of the secondary lumen 11 is smaller than the length of the sheath 3, the secondary lumen 11 being fluidly connected to the fluid access 13 at the side towards the proximal end 6.
The material of the multi-lumen tubing structure 1 needs to have a certain rigidity in order to protect the endoscope and to bend to a certain extent so as to extend into the lesion site together with the endoscope, in addition to the safety requirements necessary for medical instruments, for example, medical grade plastics including but not limited to Polycarbonate (PC), acrylonitrile-butadiene-styrene copolymer (ABS), polyethylene terephthalate (PET), polyethylene terephthalate-1, 4-cyclohexanedimethanol (PCTG or PETG), etc. may be manufactured by extrusion molding or other processes conventional in the art. The multi-lumen tubing structure 1 may also be made of other materials commonly used in the medical device field, as long as the aforementioned requirements are met.
In some embodiments, the plurality of secondary chambers 11 are unevenly distributed about the primary chamber 10. Therefore, the vortex of gas or liquid can be formed at the opening 12 more favorably, and the lens of the endoscope can be more effectively protected from the interference of water vapor, liquid or tissue fragments and the like in the in-vivo environment.
In other embodiments, the plurality of secondary chambers 11 are evenly distributed around the main chamber 10. Therefore, the structure can be simplified, and the manufacture is convenient.
In some embodiments, the plurality of auxiliary lumens 11 differ in cross-sectional size. Therefore, the vortex of gas or liquid can be formed at the opening 12 more favorably, and the lens of the endoscope can be more effectively protected from the interference of water vapor, liquid or tissue fragments and the like in the in-vivo environment.
In other embodiments, the plurality of auxiliary lumens 11 are the same size in cross-section. Therefore, the structure can be simplified, and the manufacture is convenient.
