[0002] When a cardiology patient has effusion, blood accumulation or pus accumulation in the pericardial cavity, pericardiocentesis can be used as a treatment measure; during the pericardiocentesis operation, a pericardiocentesis needle is used, which is composed of a needle, a needle body and a needle tube, of which the needle tube is a rubber tube; when the medical staff uses the needle of the puncture needle to puncture the surgical site of the patient, another medical staff member needs to clamp the rubber tube of the puncture needle with a vascular clamp to prevent air from entering the patient's body through the rubber tube;

[0003] In the process of clamping the rubber tube of the pericardial puncture needle, because it is clamped with a vascular clamp, not only does it require additional medical personnel to assist in the operation, but the medical personnel also need to hold the vascular clamp all the time during the operation; therefore, in the process of clamping the rubber tube of the pericardial puncture needle, the workload of the medical personnel is increased. Utility Model Content

[0004] In view of the above deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a clip occluder for a pericardial puncture needle, thereby solving the problem of increasing the workload of medical staff.

[0006] Furthermore, the extrusion assembly includes a fixed block, which is fixed in the through hole. A through slot communicating left and right is opened on the fixed block. A push rod is arranged in the through slot. One end of the push rod passes through the through hole and is fixed with a push plate for extruding the first block, and the other end of the push rod passes through the through hole and is located outside the limit block.

[0007] Furthermore, a pressing plate is fixed to the other end of the push rod.

[0008] Furthermore, the clamping block is in an arc-shaped structure with an opening facing upward, and an arc-shaped groove that can fit with the arc-shaped structure of the clamping block is formed on the inner bottom of the limiting block.

[0009] Furthermore, an anti-sliding block is arranged in the sliding groove to prevent the first clamping block and the sliding block from sliding out of the sliding groove.

[0021] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

[0022] Example

[0023] The clip for pericardiocentesis needle described in this embodiment is as follows: Figure 1 , Figure 5 and Figure 6 As shown, it includes a limit block 1, which is in a "U"-shaped structure, and a clamping block 4 is provided inside the limit block 1 for clamping the rubber tube on the pericardial puncture needle on the bottom of the limit block 1; when the clamping block 4 is specifically produced, it is preferred that its left side wall contacts the left inner side wall of the limit block 1, and its right side wall contacts the right inner side wall of the limit block 1;

[0024] like Figure 1 When the first and second cams are in the same position, the first and second cams 3 are in the same position, so that the cam 3 and the first cams 3 can be moved up and down to the left and right sides of the cam 3. When the first and second cams 3 are in the same position, the cam 3 and the first cams 2 can be moved up and down to the right and left sides of the cam 3.

[0025] like Figure 1 As shown, an anti-sliding block 5 is provided in the slide groove to prevent the first block 2 and the sliding block 3 from sliding out of the slide groove; when the anti-sliding block 5 is specifically installed, it is preferably installed at the top of the slide groove. Through the design of the anti-sliding block 5, the problem of the first block 2 and the sliding block 3 easily slipping out of the slide groove during the sliding process is avoided;

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the first clamping block 2 is made of elastic material; the chute is provided with a second clamping block 9 which is engaged with the first clamping block 2. When the first clamping block 2 is engaged with the second clamping block 9, the rubber tube of the pericardial puncture needle is clamped between the clamping block 4 and the limit block 1; according to Figure 4In the specific implementation of the snap connection, the first card block 2 is in a triangular structure, and the two corners of the first card block 2 are fixed on the slider 3. Later, because the first card block 2 is elastic, the other corner can be bent in the direction of the slider 3; when the second card block 9 is specifically installed, the second card block 9 is fixed at the lower position of the slide slot. When the first card block 2 moves to the top of the second card block 9, a gap is left between the second card block 9 and the slider 3. In the natural state of the first card block 2, its horizontal length is greater than the gap left between the second card block 9 and the slider 3; when the other corner of the first card block 2 is in an extruded state, its horizontal length is greater than the gap left between the second card block 9 and the slider 3. The length of is smaller than the gap between the second card block 9 and the slider 3; therefore, when the first card block 2 approaches the second card block 9 and moves downward, the first card block 2 is squeezed by the second card block 9. After the first card block 2 is squeezed and deformed, it can pass through the gap between the second card block 9 and the slider 3 and move to the bottom of the second card block 9. At this time, the first card block 2 is not squeezed by the second card block 9 and rebounds to its original state, so that the first card block 2 is stuck under the second card block 9 to achieve a snap connection; when the first card block 2 is stuck under the second card block 9, the first card block 2 drives the slider 3 and the clamping block 4 to limit the position, such as Figure 4 In the orientation, after the clamp block 4 is limited, there is a gap between it and the limit block 1 when the rubber tube is clamped; when in use, the rubber tube of the pericardial puncture needle is placed between the clamp block 4 and the limit block 1, and then the clamp block 4 is pressed downward by hand. During the pressing process, the first clamp block 2 is squeezed and deformed by the second clamp block 9, and then moves to the bottom of the second clamp block 9 and rebounds. Finally, the first clamp block 2 is limited to the bottom of the second clamp block 9. When the first clamp block 2 is limited, the rubber tube is clamped between the clamp block 4 and the limit block 1, thereby preventing air or liquid from entering the patient's body from the rubber tube;

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the second clamping block 9 is in a triangular structure and is wedge-shaped with the first clamping block 2; the wedge-shaped fit is a special form of sliding fit, which is a sliding fit composed of two sliders with inclined surfaces, the inclined surfaces of the two wedge-shaped blocks fit together, one of the sliders moves along the X axis, and the other slider moves along the Y axis. When the two inclined surfaces slide relative to each other, a straight line sliding mode along the inclined surface is formed; the first clamping block 2 is equivalent to one of the inclined surfaces, and the second clamping block 9 is equivalent to the other inclined surface; because the second clamping block 9 is fixedly connected, the first clamping block 2 can slide along the inclined surface, and then can slide to the bottom of the second clamping block 9. Through the setting of the second clamping block 9 with an inclined surface, when the first clamping block 2 slides down, it can pass through the position of the second clamping block 9 more smoothly, so that it can be easier and more convenient to operate in the process of pressing the clamping block 4;

[0028] like Figure 1, Figure 2 , Figure 3 and Figure 4 As shown, the slide groove is provided with a through hole communicating with the outer side of the limit block 1. When the through hole is specifically opened, according to Figure 3 The orientation in the middle is preferably in a state of being connected to the left and right;

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a fixing block 10 is arranged in each through hole, the fixing block 10 is fixed in the through hole, a through slot communicating left and right is opened on the fixing block 10, a push rod 7 is arranged in the through slot, one end of the push rod 7 passes through the through hole and a push plate 8 for squeezing the first card block 2 is fixed, and the other end of the push rod 7 passes through the through hole and is located on the outside of the limit block 1; this section of the scheme as a whole constitutes an extrusion assembly for squeezing the first card block 2 from a snap-on connection state to an up and down sliding state; when the fixing block 10 is specifically installed, its front and rear side walls as well as the top and bottom are all fixed in the through hole; when the push plate 8 is specifically installed, according to Figure 2 and Figure 4 In the orientation, the left push plate 8 is fixed to the right end of the left push rod 7, and the right push plate 8 is fixed to the left end of the right push rod 7; when the first clamping block 2 is clamped below the second clamping block 9, the push plate 8 is located between the first clamping block 2 and the fixed block 10. Because the push rod 7 is connected to the push plate 8, the push plate 8 can be driven to move in the direction of the first clamping block 2 by operating the push rod 7. During the movement of the push plate 8, the first clamping block 2 can be squeezed and deformed. After the first clamping block 2 is squeezed and deformed, it can pass through the gap between the slider 3 and the second clamping block 9. Therefore, during the movement of the first clamping block 2, it can move to the top of the second clamping block 9, so that the first clamping block 2 can move up and down in the slide groove. After the first clamping block 2 moves, it can drive the slider 3 and the clamping block 4 to move upward. At this time, the rubber tube can be unclamped to facilitate the passage of liquid or gas from its interior;

[0030] In the specific implementation process, a tension spring can be installed between the fixed block 10 and the push plate 8 in the extrusion assembly. When the first clamping block 2 does not need to be extruded, the tension spring can pull the push plate 8 to move in the direction of the fixed block 10, thereby facilitating the limiting of the push plate 8.

[0031] like Figure 1 and Figure 3 As shown, a pressing plate 6 is fixed to the other end of the push rod 7; the design of the pressing plate 6 makes it more convenient and quick to push the push rod 7 to move;

[0032] like Figure 1 and Figure 5As shown, the clamp block 4 is an arc-shaped structure with an opening upward, and the inner bottom of the limit block 1 is provided with an arc-shaped groove that can fit with the arc-shaped structure of the clamp block 4; through the design of the arc-shaped structure, it is convenient to insert a finger into the clamp block 4, thereby facilitating the clamp block 4 to be pressed downward;

[0033] The length of the clamp block 4 is 2.2 cm, because the width of a human thumb is about 2 cm. With the design of a length of 2.2 cm, when we press the clamp block 4 with our thumb to move it downward, it is as convenient as possible to place the thumb on the clamp block 4, which is convenient for most people to use; if the length of the clamp block 4 is shorter than 2.2 cm, it may cause the thumb to be inconvenient to place on the clamp block 4 and press downward; if the length of the clamp block 4 is greater than 2.2 cm, it may cause a waste of resources;

[0034] In the specific use process: when it is necessary to clamp the rubber tube of the pericardiocentesis needle, first let the rubber tube pass between the clamp block 4 and the limit block 1, then press the clamp block 4 downward, the clamp block 4 slides downward along the slide groove, and the first clamp block 2 also slides downward with the clamp block 4. When the first clamp block 2 is engaged with the second clamp block 9 during the sliding process, the rubber tube is clamped between the clamp block 4 and the limit block 1; when it is necessary to stop clamping the rubber tube, press the two pressing plates 6 with the thumb and index finger respectively, so that the pressing plate 6 drives the push rod 7 and the push plate 8 moves, and the push plate 8 can squeeze the first clamping block 2 during the movement, so that the first clamping block 2 can be moved out from the position of the second clamping block 9. At this time, the rubber tube is not clamped by the clamping block 4 and the limit block 1, and gas or liquid can pass through the inside of the rubber tube; therefore, in this use process, the rubber tube is clamped by the clamping block 4 and the limit block 1, which avoids the problem of heavy workload caused by another medical staff holding a vascular clamp to clamp the rubber tube during pericardiocentesis surgery, thereby reducing the burden on medical staff.
