[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] like Figure 1-7 As shown, a cerebrovascular interventional surgery operation auxiliary system comprises a fixed arm 1 mounted on an operating table, on which an adjustment rod 2 with adjustable pitch angle is slidably arranged;

[0031] A first support plate 3 is fixedly arranged on the end of the adjusting rod 2, on which a second support plate 4 is slidably arranged, and the upper surfaces of the first support plate 3 and the second support plate 4 form a fixing seat for fixing the puncture site;

[0032] The latching teeth 34 provided on the side of the first support plate 3 are engaged with the locking tongue 35 provided on the second support plate 4 to lock the second support plate 4;

[0033] The locking tongue 35 is an elastic member having a folded portion.

[0034] Specifically, a folding bag 21 is provided on the adjustment rod 2, and the folding bag 21 is connected to the air pump through the air supply pipe 12. The air pump can be provided on the fixed arm 1, and can also be provided at a position on the operating table that is convenient for the doctor to operate. The folding bag 21 is expanded by supplying air to the air pump, thereby driving the adjustment rod 2 to tilt upward, so that the fixed seat composed of the first support plate 3 and the second support plate 4 is rotated to an appropriate position.

[0035] Furthermore, during interventional surgery, the patient's puncture site thigh or wrist is fixed on the fixed seat, and then the air pump is started to supply air to the folding bag 21, so that the adjustment rod 2 is tilted upward and drives the puncture site to rise, thereby promoting blood to gather at the heart, and the blood in the raised site flows back, thereby reducing the amount of bleeding during puncture. The second support plate 4 can be adjusted according to the width of the puncture site, and the locking tongue 35 on the second support plate 4 is engaged with the latch 34. During the sliding process, the locking tongue 35 slides along the inclined surface of the latch 34, and the folding part on the locking tongue 35 is folded and contracted, so that the locking tongue 35 is staggered with the latch 34, until the locking tongue 35 passes through the latch 34, the elasticity of the folding part is released and drives the locking tongue 35 to engage with the latch 34 again, so that the second support plate 4 can slide according to demand, and naturally lock after the sliding stops, which can meet the needs of different patients for the puncture site and facilitate medical staff to perform puncture.

[0036] In the above technology, the second support plate 4 can be slidably adjusted according to the width of the puncture site, and naturally locked after sliding stops, which can meet the needs of different patients for the puncture site and facilitate medical staff to perform puncture. By starting the air pump to supply air to the folding bag 21, the adjustment rod 2 is tilted upward and drives the puncture site to rise, thereby promoting blood to gather to the heart, and the blood in the raised area flows back, thereby reducing the amount of bleeding during puncture.

[0037] As a further embodiment provided by the present invention, it also includes an airbag strip 31 having an expanded state and a contracted state, and the latch teeth 34 are linearly arrayed on the airbag strip 31 .

[0038] Specifically, the airbag strip 31 in the expanded state pushes the multiple latch teeth 34 from the edge of the first support plate 3 to the center line, so that the spacing between the latch teeth 34 is shortened and the locking tongue 35 is locked. The end of the locking tongue 35 is pushed by the airbag strip 31 so that the folding portion is folded. At this time, the locking tongue 35 is already in the limit state of folding, and the locking tongue 35 can no longer shrink, so that the latch teeth 34 and the locking tongue 35 are completely locked, so that the first support plate 3 and the second support plate 4 are locked; and the airbag strip 31 in the contracted state is in close contact with the edge of the first support plate 3, At this time, the latch tooth 34 is also tightly attached to the edge of the first support plate 3, and the locking tongue 35 is not deformed due to the push of the airbag strip 31. As the second support plate 4 slides, the locking tongue 35 slides along the latch tooth 34, and the folded portion on the locking tongue 35 folds and contracts, so that the locking tongue 35 and the latch tooth 34 are staggered. Until the locking tongue 35 passes the latch tooth 34, the elasticity of the folded portion is released and drives the locking tongue 35 to engage with the latch tooth 34 again, so that the second support plate 4 can slide according to demand and naturally lock after sliding stops. At this time, the second support plate 4 can be freely adjusted.

[0039] As another embodiment further provided by the present invention, an air cushion 32 connected to the airbag strip 31 is provided on the first support plate 3, and the air cushion 32 is in a filled state in a default state.

[0040] Specifically, the air cushion 32 can lift the puncture site of the patient. The soft air cushion 32 can improve the patient's comfort and prevent pressure sores caused by long-term braking. At the same time, the puncture site of the patient is pressed on the air cushion 32 under the action of gravity, so that the gas in the air cushion 32 enters the airbag strip 31, causing the airbag strip 31 to expand. At this time, the locking teeth 34 and the locking tongue 35 are completely locked, so that the first support plate 3 and the second support plate 4 are automatically locked as the patient's part is pressed down.

[0041] As another embodiment further provided by the present invention, it also includes a binding belt 5 which is arranged on the first supporting plate 3 and is used to make the puncture site close to the fixing seat.

[0042] Specifically, a control shaft 36 is rotatably provided on the first support plate 3, and the strap 5 includes a free end and a fixed end rolled up on the control shaft 36. After the patient's thigh or wrist is placed on the fixed seat, the free end of the strap 5 is pulled and wrapped around the patient's thigh or wrist, and fixed by the strap 5. The strap 5 is relatively soft to avoid excessive pressure on the puncture site, and can effectively limit the puncture site to prevent the patient's puncture site from moving due to trembling or spasm during the operation.

[0043] As another embodiment further provided by the present invention, the second support plate 4 is provided with an elastic clamp 41 which is engaged with the free end of the strap 5 , and is provided with a retention groove 43 and a guide opening 42 for guiding the user into the retention groove 43 .

[0044] Specifically, a buckle 51 is fixedly provided on the free end of the strap 5. After the free end is passed around the patient's thigh or wrist, the buckle 51 is engaged with the guide port 42. Since the strap 5 has a certain elasticity, after the hand is released, the strap 5 is deformed and pulls the buckle 51 to slide along the guide port 42, so that the buckle 51 enters the retention groove 43. The buckle 51 is locked by the elastic locking member 41 itself to prevent the strap 5 from falling off.

[0045] As another embodiment further provided by the present invention, a gear 33 tangential to the latching tooth 34 is fixedly disposed at the end of the control shaft 36 .

[0046] Specifically, the free end of the strap 5 is wound around the control shaft 36 in the default state. The strap 5 is released by pulling the free end, and the control shaft 36 is driven to rotate, so that the gear 33 rotates and is intermittently tangent to the latch tooth 34. When the strap 5 stops being pulled, the gear 33 is blocked by the latch tooth 34 and stops, preventing the strap 5 from rebounding and winding up under the action of its own elasticity.

[0047] As another embodiment further provided by the present invention, a screw rod 11 is threadedly connected to the fixed arm 1, and a pad 14 is provided at the end of the screw rod 11 to abut against the operating table.

[0048] Specifically, the fixed arm 1 has a U-shaped structure, and the internal spacing is greater than the thickness of the operating table, so that the fixed arm 1 can be placed according to the needs of the patient's puncture site. After determining the placement position, the screw 11 is rotated downward, and the end of the screw 11 drives the pad 14 to abut against the operating table to fix the fixed arm 1.

[0049] As another embodiment further provided by the present invention, the pad 14 includes a deformable arc plate 13 , and the deformable arc plate 13 is driven to arch upward to press the adjusting rod 2 .

[0050] Specifically, after the fixed arm 1 is placed on the operating table, the adjustment rod 2 is slid to an appropriate position as needed, and then the screw 11 is rotated downward. The screw 11 drives the pad 14 to resist the operating table, and causes the deformed arc plate 13 to be subjected to the reaction force of the operating table, so that it arches upward and presses against the adjustment rod 2 under pressure, thereby limiting the position of the adjustment rod 2. At this time, the positions of the fixed arm 1 and the adjustment rod 2 are fixed.

[0051] Working principle: After the fixed arm 1 is placed according to the needs of the patient's puncture site, the adjustment rod 2 is slid to the appropriate position as needed, and then the screw 11 is rotated downward. The screw 11 drives the pad 14 to resist the operating table, and the deformed arc plate 13 is subjected to the reaction force of the operating table, so that it arches upward and presses the adjustment rod 2 after being under pressure, and the adjustment rod 2 is limited. The folding bag 21 is supplied with air by the air pump so that the folding bag 21 is unfolded, thereby driving the adjustment rod 2 to tilt upward, so that the fixed seat composed of the first support plate 3 and the second support plate 4 is rotated to the appropriate position. When the second support plate 4 slides, the locking tongue 35 slides along the latch tooth 34, and the folded portion on the locking tongue 35 folds and contracts, so that the locking tongue 35 and the latch tooth 34 are staggered. Until the locking tongue 35 passes the latch tooth 34, the elasticity of the folded portion is released and drives the locking tongue 35 to engage with the latch tooth 34 again, so that the second support plate 4 can slide as needed, and naturally lock after the sliding stops. At this time, the second support plate 4 can be freely adjusted to place the patient's puncture site on the fixed seat. The patient's puncture site is pressed on the air cushion 32 under the action of gravity, so that the gas in the air cushion 32 enters the airbag strip 31. The airbag strip 31 is inflated, and the latch tooth 34 and the locking tongue 35 are completely locked at this time, so that the first support plate 3 and the second support plate 4 are automatically locked as the patient's body part is pressed down. After the free end is passed around the patient's thigh or wrist, the buckle 51 is engaged with the guide port 42. Since the strap 5 has a certain elasticity, after the hand is released, the strap 5 is deformed and pulls the buckle 51 to slide along the guide port 42, so that the buckle 51 enters the retention groove 43, and the buckle 51 is locked by the elastic locking member 41 itself to prevent the strap 5 from falling off. When the strap 5 stops being pulled, the gear 33 is blocked by the latch tooth 34 and stops, to prevent the strap 5 from rebounding and winding up under the action of its own elasticity.

[0052] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
