As shown, an atrial septum penetration kit comprises a sheath, a dilation tube 2 and a penetration tube 1, wherein the dilation tube 2 is provided with a distal end channel 2.1 positioned at the distal end of the dilation tube 2 and a proximal end channel 2.2 communicated with the distal end channel 2.1, and the inner diameter of the distal end channel 2.1 is smaller than the inner diameter of the proximal end channel 2.2 so as to form a step surface at the connecting position of the distal end channel 2.1 and the proximal end channel 2.2; a limit sleeve 5 is fixedly arranged in the proximal end channel 2.2, the limit sleeve 5 is provided with a cylindrical channel 5.1 and a frustum-shaped channel 5.2 communicated with the cylindrical channel 5.1, the cylindrical channel 5.1 is positioned at the distal end of the limit sleeve 5, a threading channel 2.3 is arranged in the side wall of the expansion pipe 2, the threading channel 2.3 comprises a first channel 2.3.1, an arc-shaped second channel 2.3.2 communicated with the first channel 2.3.1, a third channel 2.3.3 communicated with the second channel 2.3.2, an arc-shaped fourth channel 2.3.4 communicated with the third channel 2.3.3 and a fifth channel 2.3.5 communicated with the fourth channel 2.3.4, a pressing bulge 2.4 is arranged at the step surface, the pressing bulge 2.4 is provided with a communication hole communicated with the fifth channel 2.3.5, one end of the threading channel 2.3 can pass through the metal wire 3, and the threading channel 2.3 is fixedly connected with the side wall of the fifth channel 3.3 by the metal wire 3; a circular cylindrical mounting block 4 penetrated by the puncture tube 1 is fixed at the puncture tube 1, a mounting hole is formed in the circumferential surface of the mounting block 4, a first pressure sensor 4.1 is mounted in the mounting hole, the first pressure sensor 4.1 is connected with a movable block 4.3 through a spring 4.2, the movable block 4.3 can be abutted against the inner side walls of the frustum-shaped channel 5.2 and the cylindrical channel 5.1, a mounting groove is formed in the end face, close to the pressing protrusion 2.4, of the mounting block 4, a second pressure sensor 4.4 is arranged in the mounting groove, the second pressure sensor 4.4 can be pressed by the end part of the metal wire 3 and can be pressed by the pressing bulge 2.4, and the proximal end of the metal wire 3 is provided with scale marks.
The sheath tube is internally provided with a bending-adjusting pull wire. The threading channels 2.3 and the pressing protrusions 2.4 are equal in number and correspond to each other one by one, and the number of the threading channels 2.3 and the pressing protrusions 2.4 is 2-4. The elastic block 3.1 is made of a high polymer material.

As shown in the figure, in the matched process of the expansion pipe and the puncture pipe, the end part of the puncture pipe does not extend out of the expansion pipe in the pushing process of the expansion pipe, and as the mounting block is positioned in the frustum-shaped channel of the limiting sleeve when the mounting block is positioned in the limiting sleeve, the mounting block is positioned in different positions, and the measured values of the first pressure sensors are different, so that the position of the mounting block in the frustum-shaped channel can be judged according to the measured values of the first pressure sensors. And after the expansion pipe reaches the designated position, when the mounting block moves to the cylindrical channel along with pushing of the puncture pipe, the measured value of the first pressure sensor is not changed any more, so that the position of the mounting block reaching the cylindrical channel is known at the moment. When the second pressure sensor touches the end part of the metal wire, an operator knows that the end part of the metal wire is pushed quickly, but when the operator pushes the metal wire hard, the metal wire can still be pushed forwards, so that the metal wire moves in the threading channel until the pressing lug abuts against the second pressure sensor, the puncture tube cannot be pushed continuously at the moment, the pushing length of the puncture tube is ensured to be limited, and unnecessary puncture is avoided. The position of the metal wire can be finely adjusted before operation by exceeding the length of the communication hole, so that the adjustment can be performed according to the operation habit of a doctor and the body shape of a patient (the adjustment can be realized by pushing or pulling the metal wire by matching with scales at the proximal end of the metal wire), the length of the puncture tube which can be pushed by the doctor can be obtained between the two positions that the metal wire touches the second pressure sensor and the pressing bump touches the second pressure sensor, and the adjustment can be performed before operation.
While the invention has been shown and described with respect to the preferred embodiments, it will be understood by those skilled in the art that various changes and modifications may be made therein without departing from the scope of the invention as defined in the following claims.
