Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and in particular to a multi-way valve, a consumable box and an interventional surgery robot used for interventional surgery. Background Art

[0002] Interventional therapy is a minimally invasive treatment that uses medical imaging equipment to introduce precision, long, straight interventional consumables such as catheters and guidewires into the human body, thereby diagnosing and locally treating body pathologies through remote control.

[0003] Multi-way valves (such as Y-valve or T-valve) are commonly used medical auxiliary equipment in interventional surgery. They are mainly used to assist in the introduction of contrast agents or saline and other liquids and to guide the introduction of interventional consumables such as guide wires or catheters into the human body, and to seal to prevent blood reflux during interventional surgery. In addition, before guiding the interventional consumables into the human body, the multi-way valve needs to inject the above liquid into its interior to squeeze and expel the air in the valve to prevent the gas in the valve from entering the human body and causing air embolism, which can cause danger.

[0004] In the existing multi-way valve, a sealing plug rotating head is used to press the sealing rubber plug and the sealing pressing sheet onto one end of the multi-way valve body, and the sealing plug rotating head is manually rotated to control the closing and opening of the channel leading to the multi-way valve body. For example, by rotating the sealing plug rotating head to an appropriate position, it can allow long straight interventional consumables (such as guide wires, catheters, etc.) to pass through the sealing plug rotating head, the sealing pressing sheet and the sealing rubber plug to smoothly enter the multi-way valve, and can also achieve the purpose of preventing blood reflux. In addition, by loosening the sealing plug rotating head, exhaust can be performed.

[0005] However, such multi-way valves still have some shortcomings. In particular, the manual rotation operation process is cumbersome and prone to errors. For example, a doctor may forget to open or close the knob during surgery, which poses a great safety hazard to medical work. For another example, it is difficult to accurately rotate the sealing plug rotating head to the appropriate position to achieve the desired effect. Utility Model Content

[0039] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. For ease of description, only the parts related to the utility model are shown in the accompanying drawings. It should be noted that the embodiments in this application and the features in the embodiments can be combined with each other without conflict.

[0040] First of all, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense. For example, it can be a fixed connection or a detachable connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be a connection between the two elements. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances. In addition, in the description of this application, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0041] In addition, it should be noted that in the description of the present application, terms such as "upper", "inside", and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings. This is only for the convenience of description and does not indicate or imply that the structure must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the present application.

[0042] Figure 1 FIG. 1 is a schematic overall cross-sectional view of a multi-way valve according to an embodiment of the utility model, showing the use state of the multi-way valve. Figure 2 for Figure 1 A schematic cross-sectional view of a multi-way valve is shown, Figure 3 for Figure 1 An exploded view of the parts of a multi-port valve is shown.

[0043] like Figures 1 to 3 As shown, the multi-way valve V of the embodiment of the utility model comprises a main pipe 1, a branch pipe 2 and an elastic sealing sheet 3. Figure 1 As shown more clearly in FIG. 1 , the main body tube 1 of the multi-way valve V has an entry end 11 and a connection end 12. The entry end 11 is used for the first long straight interventional consumable c1 to enter the main body tube 1. The connection end 12 is used to connect the second long straight interventional consumable c2. The first long straight interventional consumable c1 can be inserted into the second long straight interventional consumable c2. The port of the entry end 11 and the port of the connection end 12 are usually arranged opposite to each other. The first long straight interventional consumable c1 can pass through the entry end 11 and finally be inserted into the second long straight interventional consumable c2.

[0044] Here, the long straight interventional consumables refer to consumables such as catheters, guidewires, and stents that intervene in human blood vessels. Such long straight interventional consumables are usually discarded after one-time use. The first long straight interventional consumable c1 used in combination with the multi-way valve V according to the embodiment of the utility model can be, for example, a guidewire or a stent; the second long straight interventional consumable c2 can receive the first long straight interventional consumable c1, for example, a catheter. Figure 1As shown, the first long straight interventional consumable c1 enters the main body tube 1 from the entry end 11 of the main body tube 1, extends from the connection end 12, and is thus inserted into the second long straight interventional consumable c2. Taking the first long straight interventional consumable c1 as a guide wire and the second long straight interventional consumable c2 as a catheter as an example, in an interventional surgery, the catheter c2 is generally fixed to the connection end 12 of the multi-way valve V before the guide wire c1 penetrates the multi-way valve V, and the intervention end of the guide wire c1 is located outside the catheter c2, guiding the movement of the catheter c2.

[0045] like Figures 1 to 3 As shown, the main tube 1 also has a tube wall 13 extending between the entry end 11 and the connection end 12, and a liquid inlet 13a is also provided on the tube wall 13. The branch tube 2 of the multi-way valve V is formed to extend from the liquid inlet 13a to the outside of the main tube 1, and is used to inject medical liquid into the main tube 1. The specific location of the liquid inlet 13a is not limited. The branch tube 2 can be integrally formed with the main tube 1 by, for example, injection molding, or it can be formed separately from the main tube 1 and sealed together by an appropriate method. In addition, as an example only and not a limitation, the branch tube 2 can be a straight tube or a curved tube; the branch tube 2 can have, for example, the form of a Luer male connector, or it can be a plain tube.

[0046] According to the needs of the operation performed by the multi-way valve V, different medical liquids can be injected into the main tube 1 through the branch tube 2. For example, the injected medical liquid can be physiological saline, contrast agent or heparin.

[0047] According to the embodiment of the utility model, the multi-way valve V further includes an elastic sealing sheet 3, which is arranged at the inlet end 11 of the main pipe 1. It can be understood that the specific shape of the elastic sealing sheet 3 is not limited, as long as it can cover the inlet end 11 of the main pipe 1. In this embodiment, the main body of the elastic sealing sheet 3 is a circular sheet structure as a whole. In order to explain more clearly, Figure 4 Schematic stereogram of an elastic sealing sheet that can be used in a multi-way valve according to an embodiment of the utility model. Based on the sheet structure of the elastic sealing sheet 3, the elastic sealing sheet 3 has a first surface 3-1 facing the outside of the main body tube 1 and a second surface 3-2 facing the inside of the main body tube 1. Of course, the specific thickness of the elastic sealing sheet 3 is not limited. In the case where the thickness of the elastic sealing sheet 3 is large and the width is small, the elastic sealing sheet 3 may present a block-like structure. Figure 4 As shown, the first surface 3-1 of the elastic sealing sheet 3 is provided with a first slit 3a, and the second surface 3-2 is provided with a second slit 3b. Figure 4It should be noted that the elastic sealing sheet 3 can be a sheet-like structure without an interlayer, the first slit 3a is arranged on the right part, and the second slit 3b is arranged on the left part, that is, the first surface 3-1 and the second surface 3-2 each occupy a part of the thickness in the thickness direction of the elastic sealing sheet 3; the elastic sealing sheet 3 can also be a sheet-like structure with an interlayer, that is, the first surface 3-1 and the second surface 3-2 are respectively located on two sheet-like structures connected at the edges, and there may be a gap between the two sheet structures, or there may be no gap.

[0048] According to the embodiment of the utility model, Figure 4 and Figure 5 As shown, at least a portion of the first slit 3a and at least a portion of the second slit 3b are formed as a connecting slit that penetrates in the thickness direction of the elastic sealing sheet 3. The specific shapes of the first slit 3a and the second slit 3b and their specific sizes in the width direction are not limited, as long as a connecting slit that penetrates in the thickness direction can be formed. For example, Figure 4 In the example shown, the two slits are in the shape of a straight line and a cross. Figure 5 In both examples shown, a straight connecting slit is formed. The connecting slit is used for allowing the first long straight interventional consumable c1 such as a guide wire to pass through the elastic sealing sheet 3, while closely fitting the first long straight interventional consumable c1 (see Figure 1 ) to prevent fluid from flowing out.

[0049] When the first long straight interventional consumable c1 has not penetrated the elastic sealing sheet 3, the two connecting slits are tightly closed, and the sealing effect of the entry end 11 of the main tube 1 is maintained to the greatest extent through the two connecting slits distributed sequentially along the thickness direction; when the first long straight interventional consumable c1 penetrates the elastic sealing sheet 3, the two connecting slits are deformed in turn by external force to allow the first long straight interventional consumable c1 to penetrate, and the connecting slits are tightly fitted to the first long straight interventional consumable c1 under the elastic extrusion pressure of the elastic sealing sheet 3, thereby blocking the fluid in the main tube 1 from flowing out from the entry end 11.

[0050] It can be seen that the multi-way valve V of the embodiment of the utility model provides an elastic sealing sheet 3 having a communicating slit composed of a first slit 3a and a second slit 3b, and by arranging the elastic sealing sheet 3 at the entry end 11 of the main tube 1, the entry end 11 of the multi-way valve V can be automatically sealed, thereby simplifying the use of the multi-way valve and improving the safety of the operation. This effect is particularly prominent and important when the interventional surgery requires complex operations.

[0051] According to the embodiment of the utility model, advantageously, the first slit 3a of the elastic sealing sheet 3 may include a plurality of radial slits arranged rotationally symmetrically. Preferably, the first slit 3a may be one of a cross-shaped slit, a straight-line slit and a Y-shaped slit, and the second slit 3b may be a straight-line slit. Return to reference Figure 5 , Figure 5 The middle figure (a) shows an example, in which the first slit 3a of the elastic sealing sheet 3 is a cross-shaped slit, and the second slit 3b is a straight-line slit. Figure 5 The middle figure (b) shows another example, in which the first slit 3a of the elastic sealing sheet 3 is a straight slit, the second slit 3b is a straight slit, and the length of the first slit 3a is greater than the length of the second slit 3b.

[0052] By setting the first slit 3a and the second slit 3b to different shapes or sizes, the elastic sealing sheet 3 can better allow the long straight intervention consumable to penetrate and seal the entry end 11, so as to Figure 5 Taking the example shown in the middle figure (a) as an example, the I-shaped slit 3a has a smaller deformation amount when squeezed by the medical liquid, which can better maintain the sealing of the entry end 11, while the cross slit 3b can better allow long straight interventional consumables to pass through.

[0053] The shape, size and number of the first slit 3a and the second slit 3b in the above example are only for illustration, as long as the connecting slits provided on the elastic sealing sheet 3 provide moderate resistance when the long straight interventional consumable is inserted and the sealing is maintained.

[0054] It should be understood that, although the elastic sealing sheet 3 shown in the drawings is composed of only a single elastic sheet, the elastic sealing sheet may also be composed of more than two elastic sheets according to actual process requirements. For example, one elastic sheet is provided with a straight-line connecting slit, and the other elastic sheet is provided with a cross-shaped connecting slit, and the two elastic sheets are stacked to obtain an elastic sealing sheet having a cross-shaped slit on one side and a straight-line slit on the other side.

[0055] Figure 6 To show Figure 4 A variation of the elastic sealing sheet shown in the figure, wherein the second surface 3-2 of the elastic sealing sheet 3 may be provided with a convex conical surface 3-2a, Figure 6 The side view of such an elastic sealing sheet 3 is shown, and the conical surface 3-2a can face the inside of the main tube 1 and can also have a taper of 1:1 to 5:1. By providing a convex conical surface 3-2a, the medical liquid injected into the multi-way valve V can squeeze the conical surface 3-2a, so that the slit on the conical surface 3-2a is more tightly closed, or closely fits the first long straight interventional consumable c1 inserted into the slit, thereby further improving the sealing performance of the elastic sealing sheet 3.

[0056] It should be understood that Figure 6 The tapered surface 3 - 2 a shown is merely exemplary and constitutes only a portion of the second surface 3 - 2 ; in other examples, the second surface 3 - 2 may be formed as a convex tapered surface 3 - 2 a as a whole.

[0057] Optionally, the multi-way valve V of the embodiment of the utility model may further include a sealing top cap 4, which is used to fix the elastic sealing sheet 4 to the inlet end 11 of the main pipe 1. Figure 7 As shown, the sealing top cap 4 may be provided with an opening 4a and an annular boss 4b surrounding the opening 4a. Figure 2 and Figure 3 The sealing cap 4 is fixedly connected to the entrance end 11 of the main body tube 1, so that the opening 4a exposes the first slit 3a of the elastic sealing sheet 3, and the edge of the elastic sealing sheet 3 is clamped between the annular boss 4b and the entrance end 11. By using the annular boss 4b to press the edge of the elastic sealing sheet 3, not only can the elastic sealing sheet 3 be fixed, but also the sealing performance of the elastic sealing sheet 3 can be improved. In addition, the elastic sealing sheet 3 can be fixedly connected to the entrance end 11 of the main body tube 1 by bonding or other fixing methods.

[0058] Figure 8 This is a schematic partial enlarged cross-sectional view of the inlet end of the multi-way valve according to an embodiment of the utility model. Optionally, the shortest distance d between the liquid inlet 13a and the elastic sealing sheet 3 in the axial direction of the inlet end 11 is less than or equal to 1 cm, preferably, less than or equal to 0.5 cm. Return to reference Figure 2 , inject the medical liquid from the branch tube 2 into the main tube 1 (refer to Figure 2 When the injection direction is D), the medical liquid will Figure 2 The air in the main tube 1 is gradually squeezed toward the connection end 12 in the direction indicated by the dotted arrow; the connection end 12 is connected to the outside, and the injected medical liquid squeezes most of the air out from the connection end 12 of the main tube 1, while a small part of the air may be retained at the connection end 11 of the main tube 1, specifically, in the space between the liquid inlet 13a and the elastic sealing sheet 3. By configuring the above distance d to be as small as possible, the air retained at the inlet end 11 can be advantageously reduced or even eliminated.

[0059] Reference Figure 2 and Figure 8 Advantageously, the axial direction of the branch pipe 2 and the axial direction of the inlet end 11 can be substantially perpendicular, for example, at an angle of 90°±5°, so as to more effectively squeeze the gas to the connection end 12, thereby reducing the air trapped in the inlet end 11. It should be understood that the above angle is only for illustration.

[0060] Return to reference Figure 1 and 3 The multi-way valve V of the embodiment of the utility model may further include a rotating joint 5, which is connected to the connecting end 12 of the main tube 1 and is used to connect the second long straight interventional consumable c2 and drive the second long straight interventional consumable c2 to rotate. Fig. 9 for Figure 1 The schematic perspective view of the rotating joint shown in FIG. Figure 2 The rotating joint 5 may include a Luer female joint 51 and a rotating gear 52, wherein the rotating gear 52 is integrally formed on the outer periphery of the Luer female joint 51. The Luer female joint 51 may be integrally formed with the rotating gear 52 by, for example, injection molding. Return to reference Figure 1 One end of the Luer female connector 51 is used to connect the second long straight interventional consumable c2, and the other end is connected to the connection end 12 of the main tube 1. The rotating gear 52 is rotated by an external driving force to drive the Luer female connector 51 to rotate, and the second long straight interventional consumable c2 is also driven to rotate because it is fixedly connected to the Luer female connector 51.

[0061] The embodiment of the utility model forms the Luer female connector 51 and the rotating gear 52 in one piece, thereby eliminating the need to manually install the separate Luer female connector 51 and the rotating gear 52 before performing an interventional surgery, thereby saving surgery time and reducing the risk of introducing contamination during the manual installation process.

[0062] Return to reference Figure 2 and Figure 3 Optionally, the multi-way valve V may further include a sealing ring 6 and a sealing gland 7, wherein the sealing ring 6 is clamped between the rotating joint 5 and the top end of the connecting end 12, and the sealing gland 7 is sleeved on the connecting end 12 and connected to the rotating joint 5 to axially fix the rotating joint 5 on the connecting end 12. The sealing performance of the connection between the connecting end 12 of the multi-way valve V and the rotating joint 5 can be further improved by providing the sealing ring 6 and the sealing gland 7.

[0063] The multi-way valve V of the embodiment of the utility model can be used in a consumable box B for an interventional surgical robot. Fig.10 1 is a schematic three-dimensional diagram of such a consumable box, in which a part of the housing is removed to expose the internal structure, and only the structure related to the present invention is shown in the internal structure.

Advantageously, the consumable box B according to the embodiment of the utility model further includes an input transmission shaft B2 and a second gear B3, the second gear B3 is arranged on the input transmission shaft B2 and meshes with the first gear 52, thereby transmitting the rotational motion of the input transmission shaft B2 to the rotating joint 5 (see Fig.13 ). Optionally, the gear used in the consumable box B can be a bevel gear.

[0065] The consumable box B of the embodiment of the utility model naturally has corresponding characteristics and effects due to the use of such a multi-way valve V, which will not be described in detail here.

[0066] The multi-way valve V of the embodiment of the utility model can also be used in an interventional surgery robot. Fig.11 FIG. 1 is a schematic three-dimensional diagram of such an interventional surgical robot.

The consumable box B is connected to the driving device R2 for holding and driving the long straight interventional consumables.

[0067] The interventional surgical robot can provide power for the consumable box B to drive the long straight interventional consumables c1, c2, etc. through the driving device R2. Fig.11 As an example only and not a limitation, the driving device R2 can move along the main body R1 in the first direction X, thereby driving the consumable box B to move along the first direction X, and the consumable box B holds the long straight intervening consumable, so the long straight intervening consumable is also driven to move along the first direction X. In addition, the consumable box B can also be driven by the driving device R2 to drive the long straight intervening consumable to rotate, which will be described in detail below.

[0068] From the perspective of space saving and aseptic isolation, the drive unit R2 can be Fig.11 As shown in FIG. , the driving device R2 is built into the main body R1 of the interventional surgery robot. It should be understood that, in some examples, the driving device R2 may also be external to the main body R1 of the interventional surgery robot.
