DETAILED DESCRIPTION
[0021] The following description provides many different embodiments or examples for implementing different features of the present invention. The components and arrangements described in the following specific examples are only used to simplify the present invention and are only used as examples, not to limit the present invention.
[0022] In each embodiment of the present application, "proximal" and "distal" refer to the position of the ureteral sheath and its accessories relative to the user in the use environment, wherein the end closer to the user is designated as the "proximal" and the end farther from the user is designated as the "distal".
[0023] The present application embodiment provides a packaging box 10 for a ureteral sheath, referring to Figures 1 to 9 As shown, the packaging box 10 disclosed in the embodiment of the present application includes a box body 100, a first stopper 200 and a second stopper 300. The box body 100 is used to install the ureteral sheath 20, and the first stopper 200 and the second stopper 300 are used to limit the ureteral sheath 20.
[0024] refer to Figure 1 As shown, the box body 100 has a sheath body groove 110 and a sheath tube groove 120 that are interconnected. The sheath body groove 110 is used to accommodate the sheath body 22 of the ureteral sheath 20, and the sheath tube groove 120 is used to accommodate the sheath tube 21 of the ureteral sheath 20. The groove wall of the sheath tube groove 120 is also provided with a limiting protrusion 130, which is used to limit the sheath tube 21 to prevent the sheath tube 21 from escaping from the sheath tube groove 120 along the thickness direction of the box body 100.
[0025] The ureteral sheath 20 includes a sheath body 22 and a sheath tube 21, wherein the sheath body 22 is located at the proximal side of the sheath tube 21. It can be understood that the sheath tube groove 120 is a portion of the box body 100 that provides a space for accommodating the sheath tube 21 of the ureteral sheath 20, and it roughly matches the shape of the sheath tube 21. The sheath body groove 110 is a portion of the box body 100 that provides a space for accommodating the sheath body 22 of the ureteral sheath 20, and it roughly matches the shape of the sheath body 22. When the ureteral sheath 20 is placed in the box body 100, the box body 100 provides a protective function on the periphery of the ureteral sheath 20 to prevent the ureteral sheath 20 from being damaged.
[0026] The limiting protrusion 130 is a snap-fit structure on the box body 100. When the ureteral sheath 20 is placed in the box body 100, the limiting protrusion 130 can be locked with the sheath tube 21 to prevent the sheath tube 21 from slipping out along the thickness direction of the box body 100, thereby improving the assembly reliability of the ureteral sheath 20 and the box body 100. The thickness direction of the box body 100 is the depth direction of the sheath tube groove 120 or the sheath body groove 110.
[0027] The first stopper 200 is arranged at the opening side of the sheath body groove 110, and is used to cooperate with the sheath body 22 located in the sheath body groove 110 to prevent the sheath body 22 from being separated from the box body 100. Compared with the prior art that uses a buckle connection method to fix the sheath body 22, the embodiment of the present application uses the first stopper 200 to cooperate with the box body 100 to limit the accommodating space of the sheath body 22, thereby achieving the effect of limiting the sheath body 22. In this way, the first stopper 200 can be installed on the box body 100 to complete the limiting of the sheath body 22, or the first stopper 200 can be removed from the box body 100 to cancel the limiting effect of the sheath body 22, and the operator can directly take the sheath body 22 out of the sheath body groove 110. The operation steps are simple and convenient, and it is easier to take the sheath body 22 of the ureteral sheath 20.
[0028] The embodiment of the present application is also provided with a second stopper 300, which is provided at the opening side of the box body 100, and is located outside the first stopper 200, and is used to cooperate with the ureteral sheath 20 and the first stopper 200 in the box body 100 to prevent the ureteral sheath 20 and the first stopper 200 from being separated from the box body 100. The second stopper 300 can cooperate with the entire ureteral sheath 20, and the second stopper 300 can limit the first stopper 200 to prevent the position of the first stopper 200 from being offset, thereby improving the stability of the cooperation between the first stopper 200 and the sheath body 22.
[0029] The limiting protrusion 130 is generally arranged at the groove wall position of the sheath groove 120, and the sheath 21 is located in the space between the limiting protrusion 130 and the groove bottom of the sheath groove 120. During the process of installing or removing the sheath 21, the limiting protrusion 130 can be deformed with the box body 100 under the pressure of the sheath 21, so that the sheath 21 can smoothly pass through the space limited by the limiting protrusion 130.
[0030] The sheath tube groove 120 is used to install the sheath tube 21. Therefore, when the sheath tube 21 is installed in the sheath tube groove 120, the length direction of the sheath tube 21 can be used as the length direction of the sheath tube groove 120. Since the sheath tube 21 is generally a slender structure, the plurality of limiting protrusions 130 provided in the sheath tube groove 120 are generally arranged along the length direction of the sheath tube groove 120, so as to expand the extension range of the limiting protrusions 130 and improve the limiting effect of the limiting protrusions 130 on the sheath tube 21. The limiting protrusions 130 are generally arranged in pairs, and a pair of limiting protrusions 130 are respectively located at the groove walls on opposite sides of the sheath tube groove 120 to limit the sheath tube 21 to the center position of the sheath tube groove 120.
[0031] The limiting protrusion 130 closest to the sheath groove 120 among the plurality of limiting protrusions 130 is defined as the first limiting protrusion 131. Along the length direction of the box body 100, the distance between the first limiting protrusion 131 and the sheath groove 110 is greater than or equal to half the length of the sheath groove 110. The box body 100 is used to accommodate the ureteral sheath 20, so the length direction of the box body 100 is the length direction of the ureteral sheath 20.
[0032] The distance between the first limiting protrusion 131 and the sheath body groove 110 should not be too close. In the process of taking out the ureteral sheath 20, it is necessary to first remove the second stopper 300 and the first stopper 200, and then directly take the sheath body 22 and take the sheath body 22 out of the sheath body groove 110. The sheath body 22 and part of the sheath tube 21 can be separated from the box body 100 under the action of external force, and the part of the sheath tube 21 refers to the sheath tube 21 located on the side of the first limiting protrusion 131 close to the sheath body groove 110. The closer the first limiting protrusion 131 is to the sheath body groove 110, the shorter the part of the sheath tube 21 that can be separated from the box body 100, and the farther the first limiting protrusion 131 is from the sheath body groove 110, the longer the part of the sheath tube 21 that can be separated from the box body 100. The portion of the sheath tube 21 located on the other side of the first limiting protrusion 131 is restricted by the first limiting protrusion 131 and other limiting protrusions 130 and will not move with the sheath body 22 . The sheath tube 21 on both sides of the first limiting protrusion 131 will deform to adapt to the height position change of the sheath tube 21 on both sides.
[0033] When the sheath 22 is taken out of the box body 100 by the same distance, the closer the first limiting protrusion 131 is to the sheath groove 110, the greater the deformation of the sheath tube 21 on both sides of the first limiting protrusion 131 needs to be, and the greater the force required to take the sheath 22 and the part of the sheath tube 21 connected to the sheath 22. Since the connection between the sheath tube 21 and the sheath 22 is relatively fragile, the greater the force on the ureteral sheath 20, the easier it is to damage the connection part 161 between the sheath tube 21 and the sheath 22, thereby affecting the normal use of the ureteral sheath 20.
[0034] Therefore, by limiting the distance between the first limiting protrusion 131 and the sheath body groove 110, the length of the tube section of the sheath tube 21 that can follow the movement of the sheath body 22 is increased, the deformation of the sheath tube 21 on both sides of the first limiting protrusion 131 is reduced, the magnitude of the force acting on the sheath body 22 and the part of the sheath tube 21 connected to the sheath body 22 is reduced, and the possibility of damage to the connection position between the sheath tube 21 and the sheath body 22 is reduced or even avoided.
[0035] There are multiple ways to take out the ureteral sheath 20 from the box body 100. In one way, the sheath body 22 and the sheath tube 21 are held, and the sheath tube 21 and the sheath body 22 are directly taken out along the thickness direction of the box body 100. The limiting protrusion 130 is deformed with the box body 100 under the abutment of the sheath tube 21 to form an escape space for the sheath tube 21 to pass through, so that the sheath tube 21 can be smoothly taken out of the box body 100. In another way, the sheath body 22 is first lifted to a certain height, the limiting effect of the groove wall of the sheath body groove 110 on the sheath body 22 is released, and then the sheath body 22 is moved along the length direction of the box body 100, and the sheath tube 21 is directly pulled out from the sheath body groove 110. In this way, it is possible to avoid excessive abutment between the sheath tube 21 and the limiting protrusion 130, and to avoid damage to the sheath tube 21.
[0036] Along the length direction of the box body 100, the distance between the first limiting protrusion 131 and the sheath body groove 110 is limited to be greater than or equal to half the length of the sheath body groove 110, so that the sheath body 22 can be lifted out of the box body 100 under the driving force of a smaller force, while avoiding damage to the connecting part 161 of the sheath body 22 and the sheath tube 21.
[0037] Since part of the sheath tube 21 is lifted together with the sheath body 22, during the process of pulling the sheath tube 21 out of the sheath tube groove 120, the height of the part of the sheath tube 21 located on the side of the first limiting protrusion 131 close to the sheath body groove 110 is higher than the height of the part of the sheath tube 21 located on the other side of the first limiting protrusion 131. Therefore, the pressing force between the part of the sheath tube 21 located on the side of the first limiting protrusion 131 close to the sheath body groove 110 and the first limiting protrusion 131 is greater than the pressing force on the other side, which will increase the resistance encountered by the sheath tube 21 during the pulling out process.
[0038] In some embodiments of the present application, the distance between the first limiting protrusion 131 and the bottom of the sheath groove 120 is gradually increased along the direction from the sheath groove 120 to the sheath body groove 110. With such a layout, the lifting space of the part of the sheath 21 located on the side of the first limiting protrusion 131 close to the sheath body groove 110 is expanded, so that the force between the sheath 21 and the first limiting protrusion 131 can be reduced, so as to reduce the resistance of the sheath 21 during the withdrawal process.
[0039] In some optional embodiments, the first stopper 200 may be a smaller structure. The first stopper 200 is directly mounted above the sheath body groove 110 , contacts a portion of the sheath body 22 , and limits the sheath body 22 .
[0040] In some other optional embodiments, the size of the first stopper 200 can be set to be larger. The first stopper 200 can cover the open side of the sheath groove 110 and completely cover the open side of the sheath groove 110. On the one hand, it can improve the limiting effect of the sheath groove 110, and on the other hand, it can also make the sheath 22 more evenly stressed when it is limited by the first stopper 200.
[0041] The first stopper 200 has a limiting groove 210, which is used to accommodate the sheath 22 located in the sheath groove 110. Compared with the sheath tube 21, the sheath 22 is wider and thicker. When the depth of the sheath groove 110 is shallow, part of the sheath 22 is easy to protrude from the sheath groove 110. The first stopper 200 is provided with a corresponding limiting groove 210, referring to Figure 6 and Figure 7 The limiting groove 210 can accommodate part of the sheath body 22 while the sheath body 22 can also limit the first stopper 200 and fix the relative position of the first stopper 200 and the box body 100 .
[0042] In some embodiments of the present application, the box body 100 further has a stopper protrusion 140 protruding toward the opening side thereof, Figure 1 and Figure 2 As shown. The stop protrusion 140 cooperates with the first stop member 200 in the axial upper limit position of the box body 100. The axial direction of the box body 100 is the length direction of the box body 100. The stop protrusion 140 limits the position of the first stop member 200 in the axial direction of the box body 100, so as to quickly install the first stop member 200 to a preset position.
[0043] In some preferred embodiments, the box body 100 has a first avoidance groove 150 for accommodating the finger joint, and the first avoidance groove 150 is connected to the sheath body groove 110 and the sheath tube groove 120 at the same time, and part of the first avoidance groove 150 is covered by the first stopper 200, and part of the first avoidance groove 150 is located outside the first stopper 200. The first avoidance groove 150 is used to accommodate the finger joint, which is convenient for the operator to put the finger into the first avoidance groove 150, and extend it under the first stopper 200 to remove the first stopper 200. The bottom of the first avoidance groove 150 serves as the fulcrum of the operator's finger joint, which is convenient for the operator to apply force to separate the first stopper 200 from the box body 100.
[0044] The second stopper 300 can be set as a cover structure, directly covering the opening side of the box body 100. In some preferred embodiments, the second stopper 300 can be set as a sheet structure, which covers the opening side of the box body 100 and is fixedly connected to the box body 100. The sheet structure can be a film, which has lower cost and can simplify the assembly process of the packaging box 10. Since there is also a first stopper 200 between the sheath body 22 and the second stopper 300, the first stopper 200 can protect the sheath body 22. Even if the second stopper 300 is a sheet structure, the packaging box 10 can still protect the sheath body 22. Since the sheath tube 21 is too slender, the sheath tube 21 is always in the sheath tube groove 120 and is not easily damaged by the outside.
[0045] The box body 100 has a connection portion 161 located on the open side thereof, referring to Figure 3 As shown, the connecting portion 161 is an annular structure, and the connecting portion 161 is sleeved outside the sheath groove 120 and the sheath body groove 110. The connecting portion 161 is fixedly connected to the second stopper 300 to form a sealed space between the second stopper 300 and the box body 100 to prevent the ureteral sheath 20 from being disturbed by the external environment.
[0046] In some preferred embodiments, the box body 100 further has a recessed portion 162 located on its open side, the recessed portion 162 is located outside the connecting portion 161, and the recessed portion 162 is recessed relative to the bottom of the box body 100, refer to Figure 3 As shown. Since the recessed portion 162 is recessed, a tearing gap 163 can be formed between the recessed portion 162 and the second stopper portion. Figure 4 and Figure 5 The tearing gap 163 helps the operator to pinch the second stopper 300, thereby applying force to the second stopper 300 and tearing the second stopper 300 off the connecting portion 161. The tearing gap 163 can increase the disassembly speed of the second stopper 300 and further increase the removal speed of the ureteral sheath 20.
[0047] Further preferably, the recessed portion 162 includes a main tearing portion 162a located at a corner of the box body 100, Figure 3 and Figure 5 As shown, the main tearing portion 162a can also extend and expand toward the inside of the box body 100, thereby increasing the area of the main tearing portion 162a. The larger the area of the main tearing portion 162a, the more second stoppers 300 can be pinched by the operator when tearing the second stoppers 300, and the easier it is to tear the second stoppers 300 off the box body 100. The main tearing portion 162a extends and expands toward the inside of the box body 100, and the connecting portion 161 located inside the main tearing portion 162a also moves accordingly.
[0048] In addition, the main tearing portion 162a is also provided with a connecting protrusion 164, which is connected and fixed to the second stopper 300. The connecting protrusion 164 can fix the second stopper 300 corresponding to the main tearing portion 162a, so as to prevent the unfixed part of the second stopper 300 from being folded or rubbed against other objects during transportation, resulting in the separation of the second stopper 300 and the connecting portion 161. In addition, the contact area between the connecting protrusion 164 and the second stopper 300 is small, and in the process of tearing the second stopper 300, the operator can easily separate the second stopper 300 from the connecting protrusion 164, and the connecting protrusion 164 will not affect the removal speed of the ureteral sheath 20.
[0049] In order to facilitate the removal of the sheath body 22 from the sheath body groove 110, the box body 100 also has a second avoidance groove 170 and a third avoidance groove 180 connected to the sheath body groove 110, and the second avoidance groove 170 and the third avoidance groove 180 are respectively located on both sides of the axis of the sheath body groove 110. The second avoidance groove 170 and the third avoidance groove 180 can accommodate the finger joints of the operator, making it easy to take the sheath body 22 and apply force to the sheath body 22.
[0050] When the ureteral sheath 20 is installed in the packaging box 10, refer to Figure 8 and Fig. 9 As shown, the second avoidance groove 170 and the third avoidance groove 180 are respectively located on both sides of the sheath body 22, so as to facilitate taking the sheath body 22.
[0051] In some specific embodiments, the sheath body 22 includes a first sub-sheath body 22a and a second sub-sheath body 22b. Fig. 9 As shown. The first sub-sheath body 22a is connected to the sheath tube 21, and the second sub-sheath body 22b is connected to the dilator. The dilator can be inserted into the sheath tube 21. The first sub-sheath body 22a and the second sub-sheath body 22b are connected by a connecting arm 22c. When the connecting arm 22c is fixed to the two sub-sheath bodies, the positions of the two sub-sheath bodies are fixed. When the connecting arm 22c is separated from one of the sub-sheath bodies, the two sub-sheath bodies can be separated from each other, and the dilator can be taken out from the sheath tube 21.
[0052] When the sheath 22 is located in the sheath groove 110, the connecting arm 22c is located on the side of the sheath 22 away from the bottom of the sheath groove 110, and the second avoidance groove 170 and the third avoidance groove 180 are respectively located on both sides of the connecting arm 22c. In this way, when the operator takes the sheath 22, the operator's fingers will not touch the connecting arm 22c, which can avoid the situation where the first sub-sheath 22a and the second sub-sheath 22b are separated from each other due to the accidental contact with the connecting arm 22c.
[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
