For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0033] Combine the following Figure 1-Figure 8 The specific implementation of the consumable box structure of the interventional instrument of the utility model is described.

[0034] The utility model provides a consumable box structure of an interventional device, such as Figure 1 and Figure 2 As shown, it includes: a disposable main shell, including a Y-valve positioning part 110 and a guide wire positioning part 120, the guide wire positioning part 120 is provided with a linearly extending first guide wire groove 121; a Y-valve fixing module, including a Y-valve fixing lower cover 210 and a Y-valve fixing upper cover 220, the Y-valve fixing lower cover 210 is installed on the Y-valve positioning part 110, the Y-valve fixing lower cover 210 is provided with a limiting groove 211 matching the shape of the Y-type connecting valve, the Y-valve fixing upper cover 220 is hinged to the Y-valve fixing lower cover 210, and one end of the first guide wire groove 121 points to the limiting groove 211; the Y-valve fixing module has an open state and a closed state; in the open state, the Y-valve fixing upper cover 220 is away from the Y-valve fixing lower cover 210; in the closed state, the Y-valve fixing upper cover 220 is closed to the Y-valve fixing lower cover 210 and covers the limiting groove 211.

[0035] The consumable box structure of the above-mentioned interventional instrument includes a Y-valve positioning part 110 and a guide wire positioning part 120. The guide wire positioning part 120 has a linearly extending first guide wire groove 121, which plays a guiding and limiting role. The Y-valve positioning part 110 is provided with a Y-valve fixing module, which is composed of a Y-valve fixing upper cover 220 and a Y-valve fixing lower cover 210. The Y-valve fixing upper cover 220 can be hinged to the Y-valve fixing lower cover 210, and is away from the Y-valve fixing lower cover 210 when in the open state, and covers the limiting groove 211 when in the closed state. Through the Y-valve fixing upper cover 220 and the Y-valve fixing lower cover, the Y-type connection valve can be stably limited in the limiting groove 211. Medical staff can easily fix the Y-type connection valve and its guide wire stably in place, reducing the difficulty of interventional surgery. This design can improve the use stability of the Y-type connection valve, reduce the difficulty of interventional surgery, reduce the cost of surgery, and make interventional surgery more popular.

[0036] In addition, the overall structure of the consumable box is preferably a disposable consumable, which can be used once after sterilization, and can solve the problem of cross contamination. The Y-valve fixing module can quickly install and fix the Y-type connecting valve. The Y-valve fixing lower cover 210 is detachably mounted on the Y-valve positioning portion 110 of the disposable main shell, or the side edge of the Y-valve fixing lower cover 210 away from the guide wire positioning portion 120 is hingedly mounted on the Y-valve positioning portion 110, so that in the case of deflection, the Y-valve fixing lower cover 210 can be moved closer to or away from the Y-valve positioning portion 110.

[0037] In use, the quick installation steps of the Y-type connection valve are preferably as follows: the first step is as follows: Figure 7 As shown, the Y-valve fixing upper cover 220 and the Y-valve fixing lower cover are flipped open respectively, and the Y-type connecting valve is installed; the second step is as shown in FIG. Figure 6 As shown, press and assemble the Y valve fixing lower cover 210 back into place; the third step is as follows: Figure 5 As shown, press and assemble the Y-valve fixing cover 220 back into place, tighten the Y-type connecting valve, and complete the quick installation.

[0038] like Figure 1 and Figure 5 As shown, according to the consumable box structure of an interventional device provided by the utility model, the Y-valve fixing upper cover 220 faces the guide wire positioning part 120, and forms an upper cover concave part 221; in the closed state, the operating part of the Y-type connecting valve is located between the upper cover concave part 221 and the guide wire positioning part 120. Figure 4 As shown, the operating part of the Y-type connecting valve is the operating structure of the main pipe end of the Y-type connecting valve. In interventional surgery, it is necessary to press or rotate the operating part to perform the corresponding surgical operation.

[0039] In the closed state, the operating part of the Y-type connection valve is located between the upper cover concave part 221 and the guide wire positioning part 120, so that medical staff can conveniently operate the operating part of the Y-type connection valve through the upper cover concave part 221 without opening the Y-valve fixing upper cover 220, thereby enabling the Y-type connection valve to be always positioned by the Y-valve fixing module during operation. It is understandable that for different types of Y-type connection valves, the overall shape of the Y-valve fixing module and the shape of the limiting groove 211 can be adjusted accordingly to match the control mode of the Y-type connection valve.

[0040] According to a consumables box structure of an interventional device provided by the utility model, Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, the guidewire positioning portion 120 is preferably formed with a main shell concave portion 122 on one side facing the Y-valve fixing upper cover 220. In the closed state of the above-mentioned Y-valve fixing module, the main shell concave portion 122 and the upper cover concave portion 221 form a groove area 123; the guidewire of the Y-shaped connecting valve passes through the groove area 123 and extends into the first guidewire groove 121. In the closed state of the Y-valve fixing module, the guidewire passes through the groove area 123 and extends into the first guidewire groove 121, and medical staff can operate the guidewire through this area.

[0041] Specifically, since the guide wire passes through the groove area 123 and extends to the first guide wire groove 121, the medical staff can easily remove the guide wire in the groove area 123 without moving the Y-type connecting valve. This further reduces the difficulty of the operation, allowing the medical staff to easily remove the guide wire through the groove area 123 and conveniently insert the balloon or stent when the Y-valve fixing module is closed.

[0042] Furthermore, according to the consumable box structure of an interventional instrument provided by the utility model, a main shell groove 124 is formed in the disposable main shell below the groove area 123; the extension track of the guide wire is located above the main shell groove 124. The main shell groove 124 increases the depth of the groove area 123, so that the guide wire has operable space up, down, left and right, further reducing the difficulty of medical staff to pick up the guide wire and improving convenience.

[0043] like Figure 2 and Figure 6 As shown, according to the consumable box structure of an interventional instrument provided by the present invention, a lower cover concave portion 212 is formed on the side of the Y-valve fixing lower cover 210 facing the guide wire positioning portion 120. Through the lower cover concave portion 212, a spaced area is formed between the Y-valve fixing lower cover 210 and the guide wire positioning portion 120 of the disposable main shell, so that it is convenient to start disassembling or opening the Y-valve fixing lower cover 210. On the other hand, Figure 1 and Figure 5As shown, in the closed state, the lower cover concave portion 212, the Y-valve fixing upper cover 220 and the disposable main shell form a side opening 213, and the side opening 213 leads to the branch interface of the Y-type connecting valve. When it is necessary to connect a pipeline to the branch interface of the Y-type connecting valve or inject a drug, the operation can be performed through the side opening.

[0044] like Figure 1 and Figure 2 As shown, according to a consumable box structure of an interventional instrument provided by the utility model, a guidewire positioning portion 120 is hingedly mounted with a guidewire pressing cover 125. When the guidewire pressing cover 125 is closed on the guidewire positioning portion 120, the guidewire pressing cover 125 covers a portion of the first guidewire groove 121 to limit the guidewire between the guidewire pressing cover 125 and the first guidewire groove 121. After adding the guidewire pressing cover 125 to the consumable box structure of the interventional instrument, the stability of the interventional surgery can be further improved to prevent the guidewire from slipping out of the first guidewire groove 121 during the surgery.

[0045] Specifically, the guide wire positioning portion 120 is hingedly mounted with a guide wire pressing cover 125, and when the guide wire pressing cover 125 is closed on the guide wire positioning portion 120, the guide wire pressing cover 125 covers a portion of the first guide wire groove 121. In this way, the guide wire is limited between the guide wire pressing cover 125 and the first guide wire groove 121, which can more reliably limit the position of the guide wire and prevent it from slipping out of the first guide wire groove 121 during surgery.

[0046] like Figure 2 and Figure 3 As shown, according to a consumable box structure of an interventional instrument provided by the utility model, the guide wire positioning part 120 is provided with a second guide wire groove 126 whose extension direction is at an acute angle to the first guide wire groove 121. On the extension path of the second guide wire groove 126, the guide wire positioning part 120 is provided with a clamping mechanism for clamping the guide wire. The consumable box structure of the interventional instrument, especially the design of the guide wire positioning part 120, is crucial for surgical operation. In order to better meet the needs of interventional surgery, the guide wire positioning part 120 is not only provided with a linearly extending first guide wire groove 121, but also provided with a second guide wire groove 126 whose extension direction is at an acute angle to the first guide wire groove 121. Such a design allows the guide wire to be more flexibly manipulated and can be positioned at different angles. On the extension path of the second guide wire groove 126, the guide wire positioning part 120 is provided with a clamping mechanism for clamping the guide wire. This clamping mechanism can ensure that the guide wire can be firmly fixed after being inserted into the lesion position to prevent it from shifting or falling off during the operation. This design provides great convenience for subsequent operations such as alternating replacement of balloons and stents.

[0047] Especially in PCI surgery, the insertion and removal of balloons and stents require very delicate operations. Through this clamping mechanism, medical staff can easily fix the guidewire at the lesion site, and then insert the balloon or stent on this basis, which not only improves the efficiency of the surgery, but also reduces the difficulty of the operation, making interventional surgery safer and more reliable.

[0048] According to a consumable box structure of an interventional instrument provided by the utility model, the guide wire positioning portion 120 is formed with a lateral groove 131 on the extension path of the second guide wire groove 126; the clamping mechanism includes an elastic biasing member 132 installed in the lateral groove 131; the elastic biasing member 132 is pressed against one side of the second guide wire groove 126 in a natural state. When the guide wire is inserted into the second guide wire groove 126, the elastic biasing member 132 is pressed against one side of the second guide wire groove 126 in a natural state. Since the elastic biasing member 132 has elasticity and recovery, it can generate continuous pressure on the guide wire, thereby firmly fixing it in the second guide wire groove 126.

[0049] The design of the side groove 131 allows the elastic biasing member 132 to have sufficient room for movement. At the same time, since the elastic biasing member 132 is installed in the side groove 131, it can be ensured that it will not interfere with the operation and movement of the guide wire in the second guide wire groove 126, and will not generate excessive pressure or uneven clamping force on the guide wire.

[0050] Preferably, at least a portion of the side wall of the second guide wire groove 126 is formed by an elastic biasing member 132. When the elastic biasing member 132 is loosened due to external interference, the guide wire can move in the second guide wire groove 126. In a natural state, the elastic biasing member is pressed against one side of the second guide wire groove 126, clamping the guide wire in the second guide wire groove 126.

[0051] According to a consumables box structure of an interventional device provided by the utility model, Figure 3 As shown, the elastic biasing member 132 includes a biasing portion 133 and a toggle portion 134. The biasing portion 133 is hinged to the guide wire positioning portion 120; an elastic member 135 is arranged between one side of the toggle portion 134 and the groove wall of the lateral groove 131, and the other side of the toggle portion 134 faces the lateral opening of the lateral groove 131. When in use, the toggle portion 134 of the elastic biasing member 132 only needs to be manually toggled, and the elastic member 135 will be compressed, so that the guide wire can be easily placed between the biasing portion 133 and the groove wall of the other side of the second guide wire groove 126. Once manually released, the elastic member 135 will be reset, and at the same time, the toggle portion 134 will be pushed, so that the biasing portion 133 tightly clamps the guide wire. This design makes full use of the compression and reset characteristics of the elastic member 135, so that during the operation, the guide wire can be clamped quickly and accurately, thereby improving the efficiency and safety of the operation.

[0052] like Figure 8 As shown, according to a consumable box structure of an interventional instrument provided by the utility model, a plurality of positioning structures are preferably provided on the side of the disposable main shell facing away from the Y-valve positioning part 110 and the guide wire positioning part 120. The positioning structure may include any one or more of a positioning hole 101, a positioning pin and a magnetic attraction member 102. Through the positioning structure, the disposable main shell and the working platform can be quickly positioned and installed, thereby improving the operating efficiency.

[0053] Preferably, the positioning structure includes a positioning pin or a positioning hole 101 that matches the positioning hole 101 and the positioning pin on the working platform, and the positioning of the consumable box structure of the interventional instrument and the working platform is achieved through the matching of the pin hole. On this basis, the positioning structure preferably also includes a magnetic suction component 102, which can be a magnet, or a magnetic metal such as iron (Fe), nickel (Ni), cobalt (Co), etc., which increases the positioning reliability of the consumable box structure of the interventional instrument and the working platform through magnetic attraction. The consumable box of the entire interventional instrument can be quickly disassembled or installed through the above-mentioned positioning structure, which further reduces the difficulty of operation and improves surgical efficiency.
