[0039] See also Figure 1-7 The present invention provides a technical solution: a puncture hemoptysis occluder, comprising two scissor-shaped cutting pieces 1, a hollow shell 2, and a protective tube 201 installed at one end of the top surface of the shell 2 and connected to the inside of the shell 2, wherein a tube body 3 that can slide along the extension direction of the protective tube 201 is slidably connected inside the protective tube 201, and the tube body 3 is sleeved outside the two cutting pieces 1, and the tips of the two cutting pieces 1 extend to the outside of the tube body 3 in a direction away from the shell 2, and the other ends extend into the shell 2, and the middle parts of the two cutting pieces 1 are rotatably connected to the inner wall of the tube body 3;

[0040] The bottom surface of the shell 2 is also provided with a slide groove 4 extending along the length direction of the protective tube 201 and a first spring 401 located in the slide groove 4 and consistent with the extension direction thereof. The two ends of the bottom surface of the shell 2 are respectively provided with a first handle 5 and a second handle 6 slidably connected to the shell 2. The second handle 6 slides with the slide groove 4, and the second handle 6 is abutted against one end of the first spring 401. The upper end of the second handle 6 extends into the interior of the shell 2 and a linkage assembly 7 is provided between the second handle 6 and the tube body 3. When the second handle 6 slides in the direction of the first spring 401, the linkage assembly 7 drives the tube body 3 to slide toward the interior of the shell 2.

[0041] In this solution, the two cutting pieces 1 are rotatably connected to the housing 2 at the middle position to form a scissor-type structure. The rotating part of the scissor-type structure is provided with a torsion spring. Under the elastic force of the torsion spring, the end located outside the protective tube 201 is always kept in an open state, and the opening and closing states of the two ends of the scissor-type structure are not synchronized, that is, if one end of the scissor-type structure is in an expanded state, the other end is in a closed state. The expanded length of the expanded end of the scissor-type structure is not greater than the diameter length of the tube body 3;

[0042] The first handle 5 and the second handle 6 can present the following states through the first spring 401:

[0043] State 1: the first spring 401 naturally stretches and its end always pushes the second handle 6 in a direction away from the first handle 5, so that the first handle 5 and the second handle 6 remain in an open state without being affected by external forces;

[0044] In state two, the operator applies external force to the second handle 6 to cause the second handle 6 to move toward the direction of the first handle 5. Under the action of the external force, the second handle 6 overcomes the elastic force of the first spring 401 and moves toward the direction of the first handle 5. At the same time, the first spring 401 contracts and elastically stores energy.

[0045] In the state 1, the tube body 3 and one end of the cut piece 1 are exposed outside the protection tube 201 .

[0046] Before inserting the protection tube 201 into the patient's body, the operator can pick up the entire device by holding the first handle 5 and the second handle 6 with one hand at the same time. At this time, the operator's fingers and palms are in contact with the opposite sides of the first handle 5 and the second handle 6 respectively. The operator pushes the second handle 6 toward the direction of the first handle 5 by applying force with the palm, so that the first handle 5 and the second handle 6 are in state 2. In the process of the second handle 6 moving toward the first handle 5, the linkage component 7 drives the tube body 3 and the cutting sheet 1 to slide toward the inside of the shell 2, that is, to be stored in the protection tube 201;

[0047] After the tube body 3 and the cutting piece 1 are completely stored in the protective tube 201, the operator moves the protective tube 201 to the front of the patient's puncture site, and then gradually releases the pressure on the second handle 6. Under the elastic force of the first spring 401, the second handle 6 is pushed to move away from the first handle 5, so that the first handle 5 and the second handle 6 are in state one, and the cutting piece 1 is exposed outside the protective tube 201, and the puncture site of the patient can be electrocoagulated to stop bleeding.

[0048] The protection tube 201 can be made of a flexible material. The protection tube 201 is sleeved outside the tube body 3 , and the shape of the protection tube 201 can be supported by the tube body 3 .

[0049] That is, when the puncture hemoptysis occluder of the present invention is used to block the bleeding at the puncture site of the patient, the second handle 6 and the linkage assembly 7 can cooperate to store the tube body 3 and the cutting blade 1 in the protective tube 201, so as to reduce the situation where the cutting blade is exposed outside the protective tube 201 and causes accidental injury to other tissue parts of the patient. At the same time, since the protective tube 201 is made of a flexible material, when the second handle 6 and the cutting blade 1 are stored in the protective tube 201, the discomfort caused by the protective tube 201 poking other tissue parts of the patient can be reduced.

[0050] In this embodiment, the linkage assembly 7 includes a first rack portion 701, a second rack portion 702 and a gear 703 located between the first rack portion 701 and the second rack portion 702. The first rack portion 701 and the second rack portion 702 are respectively installed on the bottom surface of the tube body 3 and the top surface of the second handle 6. The tooth surfaces of the first rack portion 701 and the second rack portion 702 are opposite to each other. The first rack portion 701 and the second rack portion 702 are respectively meshed with the top surface and the bottom surface of the gear 703.

[0051] When the first handle 5 and the second handle 6 are in state one, the gear 703 is meshed with the right end and the left end of the first rack portion 701 and the second rack portion 702 respectively.

[0052] When in use, when the operator pushes the second handle 6 toward the direction of the first handle 5, the second rack portion 702 moves, and through meshing connection, drives the gear 703 and the first rack portion 701. Since the first rack portion 701 and the second rack portion 702 are meshed with the top surface and the bottom surface of the gear 703 respectively, the movement directions of the two are opposite, so that the tube body 3 moves toward the inside of the protective tube 201.

[0053] In this embodiment, an extrusion block 8 located on the sliding track of the tube body 3 is also provided in the shell 2. The extrusion block 8 is located on the sliding track of the connecting line of the two cutting pieces 1. The opposite side of the two cutting pieces 1 away from the end of the tube body 3 can be squeezed by the extrusion block 8 through sliding.

[0054] When the first handle 5 and the second handle 6 are in state one, the end of the squeezing block 8 facing the protection tube 201 is located between the ends of the two cutting pieces 1 away from the protection tube 201. The squeezing block 8 is slidably connected to the housing 2. In state one, the squeezing block 8 can move toward the direction of the protection tube 201 to cause the two cutting pieces 1 to open.

[0055] In this embodiment, the two surfaces of the extrusion block 8 close to the sliding tracks of the two cutting pieces 1 are inclined surfaces. The extrusion block 8 gradually tapers into a truncated cone shape toward the direction of the protective tube 201 through the two inclined surfaces. The two inclined surfaces are respectively located on the sliding tracks of the two cutting pieces 1.

[0056] When in use, when the distance between the rotating connection part of the extrusion block 8 and the two cutting pieces 1 is shortened, the inclined surface on the extrusion block 8 will support the end of the two cutting pieces 1 away from the protection tube 201, prompting the two cutting pieces 1 to open away from the protection tube 201, and as the distance decreases, the degree of opening of the two cutting pieces 1 will increase.

[0057] In this embodiment, a connecting rod 9 is provided in the housing 2 and is located between the extrusion block 8 and the first handle 5. One end of the connecting rod 9 is hinged to the end of the extrusion block 8 away from the cutting piece 1, and the other end is connected to the first handle 5.

[0058] The first handle 5 is rotatably connected to the housing 2 , and a fixing member 10 capable of fixing the first handle 5 or the second handle 6 is disposed in the housing 2 .

[0059] The first handle 5 is rotatably connected to the housing 2 via a torsion spring, and the first handle 5 or the second handle 6 can be fixed via a fixing member 10, so that when the operator holds the first handle 5 and the second handle 6 with one hand, the unfixed handle can move.

[0060] When in use, with the second handle 6 fixed, the operator can press the first handle 5 with his fingers to cause the first handle 5 to rotate in the direction of the second handle 6. Figure 2 The connecting rod 9 is connected to the first handle 5 and can be regarded as an extension structure of the first handle 5. Therefore, the rotation of the first handle 5 drives the connecting rod 9 to rotate synchronously in the same direction, so that the connecting rod 9 drives the extrusion block 8 to slide toward the direction of the protection tube 201, and then the extrusion block 8 extrudes the opposite side of the two cutting pieces 1 away from the end of the protection tube 201.

[0061] In this embodiment, the fixing member 10 includes a fixed block 1001 and a movable block 1002. The fixed block 1001 and the movable block 1002 are respectively provided with matching plug-in blocks and slots on opposite sides. The movable block 1002 is slidably matched with the shell 2. The plug-in block is located on the sliding track of the slot. The fixed block 1001 is connected to the first handle 5.

[0062] Among them, when the first handle 5 is in a natural state, the fixed block 1001 is located on the sliding track of the movable block 1002, and the movable block 1002 can cause the slot and the plug-in block to be plugged in by sliding. In the plugged state, the first handle 5 is restricted by the movable block 1002 and cannot rotate, thereby fixing the first handle 5.

[0063] In this embodiment, a second spring 1003 is disposed between the fixed block 1001 and the movable block 1002, and two ends of the second spring 1003 are respectively against opposite sides of the fixed block 1001 and the movable block 1002;

[0064] The housing 2 is provided with an extrusion member 11 for extruding the movable block 1002 . The extrusion member 11 is used to drive the movable block 1002 to slide in the direction of the fixed block 1001 .

[0065] When the second spring 1003 is naturally stretched, it pushes the movable block 1002 in a direction away from the fixed block 1001 through its end under the action of elastic force.

[0066] When in use, the movable member can be squeezed by the squeezing member 11 to cause the movable block 1002 to slide toward the direction of the fixed block 1001 , thereby fixing the first handle 5 .

[0067] In this embodiment, the extrusion member 11 includes a rotating cylinder 1101 and a first plate body 1102 located on the top surface of the movable block 1002. The rotating cylinder 1101 is rotatably connected to the inner wall of the shell 2, one end of the first plate body 1102 is connected to the outer surface of the rotating cylinder 1101, the movable block 1002 is located on the rotation trajectory of the first plate body 1102, and a turntable 12 coaxially connected to the rotating cylinder 1101 is provided on the outer wall of the shell 2.

[0068] During use, the operator can rotate the turntable 12 to cause the rotating drum 1101 to rotate, thereby driving the first plate body 1102 to rotate toward the direction of the movable block 1002 through the rotating drum 1101. As the first plate body 1102 gradually rotates, the movable block 1002 is pressed toward the direction of the fixed block 1001, thereby causing the movable block 1002 and the fixed block 1001 to be plugged in.

[0069] In this embodiment, a second plate 1103 is further provided on the outer surface of the rotating drum 1101 , one end of the second plate 1103 is connected to the rotating drum 1101 , and the other end can abut against a side of the second handle 6 facing the first handle 5 by rotating the rotating drum 1101 .

[0070] The connection diagram of the first plate 1102, the second plate 1103 and the rotating drum 1101 can be found in the attached manual. Figure 4 as well as Figure 6 The rotating drum 1101 can be fixed to the first handle 5 by the cooperation of the first plate 1102 and the movable block 1002 , or the second plate 1103 and the second handle 6 can be abutted against one side of the first handle 5 .

[0071] When in use, the operator can rotate the rotating drum 1101 to cause the second plate 1103 to abut against the side of the second handle 6 close to the first handle 5. At this time, when the rotating drum 1101 and the second plate 1103 are not rotating, the distance between the axis of the rotating drum 1101 and the second handle 6 is constant, which prevents the second handle 6 from moving in the direction close to the first handle 5, thereby fixing the second handle 6.

[0072] In this embodiment, a rubber pad is provided on a side of the first handle 5 and the second handle 6 that is relatively far away from each other, and an inclined anti-skid pattern is provided on the surface of the rubber pad.

[0073] Since the rubber pad is flexible, when in use, the rubber pad can improve the comfort of the operator's hand when holding it. At the same time, the anti-slip texture protruding from the rubber pad can increase the friction with the operator's hand, so that the operator can better hold it.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
