Description

Technical Field

[0001] This application relates to the field of aneurysm clip technology, and in particular to an aneurysm clip with an adjustable clip head angle. Background Technology

[0002] Aneurysm clips are medical devices specifically designed for handling and clamping aneurysms during surgery. They are primarily used in aneurysm resection surgery to clamp the blood vessels in the aneurysm, preventing blood from flowing into the aneurysm, thus preventing the aneurysm from rupturing and bleeding, and ensuring the safety of the surgery.

[0003] The existing patent document "CN210249984U A Novel Aneurysm Clip" discloses an aneurysm clip. Although the aneurysm clip in the above technical solution can clamp the aneurysm, the user needs to hold it and exert force to clamp it during the clamping operation, which is quite strenuous for a long time.

[0004] Since surgery is usually performed under a microscope, the conventional straight-bar clamp structure places the handle and the clamp head on the same axis. When operating under a microscope, the surgeon's hands and the instrument handle can easily obstruct the surgical field. At the same time, the angle adjustment is inconvenient and cannot be adjusted according to the clamping position inside the patient's head.

[0005] In other words, existing technologies have the following technical problems: ordinary aneurysm clips require the user to constantly hold and exert force during clamping operations, which is quite strenuous. Therefore, an aneurysm clip with an adjustable clamp head angle is proposed to address the above problems. Summary of the Invention

[0040] Please see Figure 1-7 As shown, an aneurysm clip with an adjustable clamp head angle includes:

[0041] A gripping component 1, one end of which is fixedly connected to a connecting rod assembly 2, and the other end of the connecting rod assembly 2 is fixedly connected to a clamp head assembly 3;

[0042] A clamp control structure is provided between the clamp head assembly 3 and the gripping assembly 1. The clamp control structure is used to control the clamp 302 to open and close.

[0043] Adjustment component 4 is fixedly disposed between grip component 1 and pliers head component 3. Adjustment component 4 is used to control the angle of pliers head component 3 by fingers when operating grip component 1 with one hand.

[0044] Through the above technical solution, the aneurysm can be clamped with less effort by using the gripping component 1 and the clamping head component 3 together. There is no need to continuously press and exert force when clamping, making it more labor-saving and convenient to use. The design of the bending structure makes the gripping part and the clamping part form a bending angle, which can effectively expose the field of vision and facilitate endoscopic operation. At the same time, this application also has an adjustment function. Through the setting of the adjustment component 4, the clamping head angle can be adjusted when operating with one hand, which makes it easier to change the angle of the clamping head for clamping operation, making it more flexible to use.

[0045] The grip assembly 1 includes a grip handle 101, a moving ring 102, a pinch plate 103, a connecting frame 104, and a moving slider 105. The pinch plate 103 is rotatably connected to both side walls of the grip handle 101, and the moving ring 102 is slidably connected to the outer surface of the grip handle 101. One end of the connecting frame 104 is rotatably connected to both side walls of the moving ring 102, and the other end of the connecting frame 104 is rotatably connected to the inner wall of the pinch plate 103. With this technical solution, when the user uses this device, by holding the grip assembly 1 with one hand and pinching the pinch plates 103 on both sides with the thumb and middle finger, the user can move the moving ring 102.

[0046] The grip 101 has an inner cavity, and a movable slider 105 is slidably connected in the inner cavity of the grip 101. The movable slider 105 is fixedly connected to the movable ring 102. Through this technical solution, the movable slider 105 can be moved by the movement of the movable ring 102.

[0047] The linkage assembly 2 includes a bent sleeve 201 and a straight sleeve 202. One end of the bent sleeve 201 is fixedly connected to one end of the grip handle 101, and the other end of the bent sleeve 201 is fixedly connected to the straight sleeve 202. Through this technical solution, the bent sleeve 201 allows the gripping and clamping parts to form a bent angle, effectively exposing the field of vision and facilitating operation under the scope.

[0048] The clamp head assembly 3 includes a clamp base 301, clamps 302, a connecting frame 303, a limiting collar 304, and a limiting slider 305. The clamps 302 are rotatably connected to both sides of the front end of the clamp base 301. One end of the connecting frame 303 is hinged to the side wall of the clamps 302, and the other end of the connecting frame 303 is hinged to the outer wall of the limiting collar 304.

[0049] The limiting collar 304 is disposed on the outer wall of the clamp seat 301 and slides with the clamp seat 301. The clamp seat 301 has an inner cavity, in which a limiting slider 305 is slidably connected. The limiting slider 305 is fixedly connected to the limiting collar 304. Through this technical solution, the movement of the limiting slider 305 can drive the limiting collar 304 to move, and the movement of the limiting collar 304 can drive the clamp 302 to rotate angularly, thus achieving clamping. Figure 3 From the perspective of the limiting collar 304, when it moves to the left, the clamp 302 can be kept clamped; when it moves to the right, the clamp 302 can be opened.

[0050] The clamp control structure includes a traction steel wire rope 306, a guide collar 307, and a clamp spring 308. One end of the clamp spring 308 is fixedly connected to one side of the limiting slider 305, and the other end of the clamp spring 308 is fixedly connected to the inner wall of the clamp seat 301. One end of the traction steel wire rope 306 is fixedly connected to the side wall of the limiting slider 305. The other end of the traction steel wire rope 306 extends through the straight sleeve rod 202 into the inner cavity of the grip handle 101. One end of the traction steel wire rope 306 is fixedly connected to the side wall of the moving slider 105. The guide collar 307 is fixedly disposed on the inner wall of the straight sleeve rod 202. An adjusting rod 409 is rotatably connected to the inner wall of the grip handle 101. The traction steel wire rope 306 passes through the guide collar 307. The wire rope 306 passes around the adjusting rod 409. Through this technical solution, the elastic action of the clamp spring 308 can push the limiting slider 305 to the left, keeping the clamp 302 in a tightly closed clamping state. When the user presses the pinch plates 103 on both sides, it can drive the moving ring 102 to move to the right, thereby driving the moving slider 105 to move to the right, which in turn pulls the traction wire rope 306, driving the limiting slider 305 to move to the right, thus opening the clamp 302. When it is necessary to clamp the aneurysm, the opened clamp 302 is moved to the clamping position, and then the pinch plate 103 is released. Through the action of the clamp spring 308, the limiting slider 305 can be pushed to the left, thus clamping the clamp 302 and realizing the clamping operation. It does not require continuous force from the hand when clamping, making it easier to use.

[0051] The adjustment assembly 4 includes an adjustment head 401, a fixed head 402, an adjustment gear 403, a gear A 404, a gear B 405, a bevel gear A 406, a transmission rod 407, a bevel gear B 408, an adjustment rod 409, a bevel gear C 410, and an adjustment knob 411. The fixed head 402 is fixedly disposed at one end of the straight sleeve rod 202. The fixed head 402 has an inner cavity. The adjustment head 401 is rotatably connected to the inner cavity of the fixed head 402. One end of the adjustment head 401 is fixedly connected to one end of the clamp seat 301.

[0052] An adjusting tooth 403 is fixedly provided on the arc-shaped wall of the adjusting head 401. A gear A404 is rotatably connected in the inner cavity of the straight sleeve rod 202. The gear A404 meshes with the adjusting tooth 403. A gear B405 is rotatably connected in the inner cavity of the straight sleeve rod 202. The gear B405 meshes with the gear A404. A bevel gear A406 is fixedly connected to the side wall of the gear B405. A transmission rod 407 is rotatably connected in the inner cavity of the straight sleeve rod 202. A bevel gear B408 is fixedly connected to one end of the transmission rod 407. The bevel gear B408 meshes with the bevel gear A406. Through this technical solution, the rotation of the transmission rod 407 can drive the bevel gear B408 to rotate, which in turn drives the bevel gear A406 to rotate, which in turn drives the gear B405 to rotate, which in turn drives the gear A404 to rotate. The rotation of the gear A404 can drive the adjusting gear 403 to rotate, which in turn drives the adjusting head 401 to rotate at an angle, thereby realizing the function of adjusting the angle.

[0053] The diameter of gear A404 is larger than that of gear B405. Through this technical solution, since the small gear transmits power to the large gear, more precise angle adjustment can be achieved.

[0054] The adjusting knob 411 is located on the outer wall of the grip 101 and is rotatably connected to the grip 101. A connecting rod 412 is fixedly connected to one end of the adjusting knob 411, and a bevel gear D413 is fixedly connected to one end of the connecting rod 412. The adjusting rod 409 is located in the inner cavity of the grip 101 and is rotatably connected to the grip 101. One end of the adjusting rod 409 is connected to one end of the transmission rod 407 via a coupling. A bevel gear C410 is fixedly connected to the arc-shaped wall of the adjusting rod 409. The bevel gear C410 and the bevel gear D413 mesh with each other. According to this technical solution, when the angle needs to be adjusted, it can be adjusted with one hand. During the adjustment operation, the palm can be kept facing upward, and the thumb and middle finger can pinch the pinch plates 103 on both sides to control the clamping. The index finger can be placed on the adjustment knob 411 to push the adjustment knob 411 to rotate. The rotation of the adjustment knob 411 can drive the bevel gear D413 to rotate, which in turn drives the bevel gear C410 to rotate, thereby driving the adjustment rod 409 to rotate. The adjustment rod 409 transmits power through the coupling, driving the transmission rod 407 to rotate, thereby realizing the function of adjusting the angle of the clamp head assembly 3.
