Description

Technical Field

[0001] The utility model belongs to the technical field of negative pressure suction, and in particular relates to an intracranial negative pressure suction device. Background Art

[0002] Cerebral thrombosis refers to a blood clot formed in the blood vessels of the brain, which blocks the normal blood flow. This situation will cause hypoxia of the nearby brain tissue, thus causing brain dysfunction and even tissue damage;

[0003] Intravascular interventional thrombectomy is currently an important treatment method for acute cerebral infarction. It is of great value in quickly achieving cerebral vascular occlusion and recanalization. Currently, commonly used thrombectomy methods include thrombectomy stents and direct thrombus aspiration technology. In both methods, a negative pressure aspiration device is used to connect the catheter to achieve thrombus aspiration or prevent thrombus escape.

[0004] Currently, commonly used negative pressure suction devices include ordinary syringes, mechanical negative pressure suction pumps, etc. The cost of mechanical negative pressure suction pumps is relatively high, so ordinary syringes are used more often. By connecting the syringe to the tail end of the suction tube and continuously suctioning with both hands, negative pressure is achieved, thereby aspirating the thrombus. However, the syringe is light in weight and is easy to move when placed on the operating table, which will cause the suction tube connected to it to move or shake. Since the suction tube needs to be inserted into the human blood vessel, if it moves or shakes, it will not only cause physical discomfort to the patient, but is more likely to affect the outcome of the operation. Therefore, the stability of the syringe is a critical factor for the success of the operation. Utility Model Content

Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0026] like Figure 1-Figure 2 As shown, an intracranial negative pressure suction device includes a negative pressure device 1 and a clamping bracket, the negative pressure device 1 includes a sleeve 101, the clamping bracket includes a gripping clamp 2 and a clamp 3, the gripping clamp 2 is used to clamp the sleeve 101, and the gripping clamp 2 is connected to the clamp 3 through a vertical rod 4;

[0027] The grabbing clamp 2 includes a clamping arm 201, which is provided with two groups. The two groups of clamping arms 201 are respectively connected to a rotating arm 2011. The two groups of rotating arms 2011 are both rotatably connected to the pressing seat 202, and the middle parts of the two groups of rotating arms 2011 are both rotatably connected to the supporting seat 204. A base plate 203 is provided on the pressing seat 202, and the base plate 203 is used to support the sleeve 101. A pressing assembly 5 is provided between the pressing seat 202 and the supporting seat 204, and also includes a clamping part 6, which is used to clamp the pressing assembly 5.

[0028] Before the operation begins, the clamping bracket can be fixed to the edge of the operating table or on the placement rack through the clamp 3, and then the sleeve 101 of the negative pressure device 1 can be placed on the base plate 203. By pressing the sleeve 101, the base plate 203 is driven to move downward along the pressing component 5. During the movement, the rotating arm 2011 rotates, and the connection between the rotating arm 2011 and the support seat 204 is used as a fulcrum, thereby driving the two sets of clamping arms 201 to rotate until the sleeve 101 is clamped, thereby achieving the fixation of the negative pressure device 1, which is convenient for the doctor's operation during the operation.

[0029] In a specific embodiment, the pressing assembly 5 includes a column 501 and a first spring 502 mounted on the column 501. The upper end of the column 501 is fixedly connected to the bottom of the pressing seat 202. The support seat 204 is provided with a first cavity 2041 at the position corresponding to the column 501, and the clamping member 6 is received in the first cavity 2041.

[0030] In a specific embodiment, an annular protrusion 5011 is provided at the bottom of the column 501, and the clamping member 6 includes an inclined block 601 and a second spring 602, one end of the second spring 602 is fixedly connected to the inclined block 601, and the other end of the second spring 602 is connected to the inner wall of the first cavity 2041, the inclined block 601 is provided with an inclined groove 6011, and a stopper 603 is provided below the inclined groove 6011, the button 605 passes through the bottom wall of the support seat 204 and is connected to the stopper 603, and a third spring 604 is provided between the stopper 603 and the bottom wall of the support seat 204.

[0031] In actual use, by pressing the sleeve 101, the bottom plate 203 is driven to move downward along the pressing component 5, the first spring 502 is compressed, the column 501 enters the first cavity 2041, and the annular protrusion 5011 squeezes the inclined block 601, so that the second spring 602 is compressed. When the column 501 completely enters the first cavity 2041, the second spring 602 releases the elastic force, so that the inclined block 601 and the annular protrusion 5011 are engaged, thereby fixing the pressing component 5, thereby achieving the gripping effect of the sleeve 101.

[0032] In a specific implementation, the two groups of clamp arms 201 and the bottom plate 203 are both configured with arc surfaces and are adapted to the surface of the sleeve 101 .

[0033] In a specific implementation manner, the vertical pole 4 is a soft tube, and a nano aluminum alloy rod core is arranged inside.

[0034] It should be noted that the nano aluminum alloy rod core has greater toughness and strong supporting force. In actual use, the gripping clamp 2 can be adjusted to different angles according to actual conditions.

[0035] In a specific implementation, the negative pressure device further includes a core rod 102 , and the core rod 102 is connected with a T-shaped clamping portion 1021 , and the T-shaped clamping portion 1021 is used to pull the core rod 102 .

[0036] In a specific implementation manner, Figure 3-Figure 4 As shown, it also includes a stretching member 7, which includes a U-shaped groove 701. A support rod 702 is connected to the bottom of the U-shaped groove 701, and the support rod 702 is connected to the support seat 204 through a telescopic component.

[0037] In a specific embodiment, the telescopic assembly includes a rotating rod 703, which is rotatably connected to the support seat 204 through a second cavity 704, a screw 7031 is provided at one end of the rotating rod 703 close to the support rod 702, a worm 7032 is provided at one end of the rotating rod 703 away from the support rod 702, the worm 7032 is meshed with a gear 706, and a threaded hole adapted to the screw 7031 is provided on the support rod 702;

[0038] A rack 705 meshing with the gear 706 is provided on one side of the column 501 close to the gear 706;

[0039] A limit rod 707 is also provided on the support seat 204 , and the limit rod 707 is slidably connected to the support rod 702 .

[0040] It should be noted that the gear 706 is arranged near the upper surface of the support seat 204. In actual use, when the negative pressure device 1 is placed on the bottom plate 203, the control core rod 102 passes through the U-shaped groove 701, and the T-shaped clamping portion 1021 is engaged with one side of the U-shaped groove 701. By pressing the sleeve 101, the bottom plate 203 is driven to move downward along the pressing component 5 at the same time, the first spring 502 is compressed, and the column 501 gradually moves into the first cavity 2041. At this time, the gear 706 rotates under the meshing of the rack 705, and the rotation of the gear 706 drives the screw 7031 to rotate through the worm 7032, thereby moving the support rod 702 away from the end of the support seat 204, so that the U-shaped groove 701 pulls the T-shaped clamping part 1021 to achieve the negative pressure state of the sleeve 101, so that the doctor does not need to specifically perform negative pressure operation on the negative pressure device, reducing the preoperative preparation work, and during the suction process, the doctor does not need to perform negative pressure operation on the negative pressure device for a long time.

[0041] In a specific implementation, rubber pads are provided on the two sets of clamping arms 201 and the side of the bottom plate 203 close to the negative pressure device 1 .

[0042] In actual use, the rubber pad can play a good anti-slip role, and the rubber pad is made of a soft material, which can protect the negative pressure device 1.
