Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of spinal surgery suction devices, and in particular relates to a suction device for spinal surgery. Background Technology
[0002] Spinal diseases refer to lesions in the bones, intervertebral discs, ligaments, or muscles of the spine, which can compress or irritate the spinal cord, nerve roots, and blood vessels, leading to a variety of complex clinical symptoms. In spinal surgery, suction devices are typically used to remove accumulated blood or tissue exudate from the surgical area to maintain a clear surgical field. However, most existing suction devices are fixed-angle micro-bends (such as 30° or 45° bends), which have significant limitations in practical operation. Because the suction direction is singular, surgeons must frequently rotate their wrists to adjust the angle. However, the range of motion of the human wrist is limited, typically not exceeding 60°, making it difficult to thoroughly remove fluid from narrow intervertebral spaces or deep surgical fields, thus affecting surgical efficiency and precision. Utility Model Content
[0003] The purpose of this invention is to provide a suction device for spinal surgery that allows for adjustment of the angle of the suction tube head, thereby improving the precision of the surgical procedure to a certain extent.
[0004] The aforementioned suction device for spinal surgery includes a bendable suction tube. A first restraint tube is fixed to the outer wall of the suction tube, and a second restraint tube is fixed to the suction tube at the left end of the first restraint tube. The same tension keel is independently inserted into the first restraint tube and the second restraint tube. The tension keel is made of elastic material, and the left end of the tension keel is fixed inside the second restraint tube.
[0005] Furthermore, the suction tube includes a main tube, with a bendable tube connected to the left end of the main tube and a movable tube connected to the other end of the bendable tube; a first constraint tube is fixed to the main tube, and a second constraint tube is fixed to the movable tube.
[0006] Furthermore, a handle is fixed to the right end of the main tube, a conduit is connected to the right side wall of the handle, and a through hole is provided on the handle to allow the conduit to communicate with the main tube.
[0007] Furthermore, the handle is equipped with a movable block that can slide left and right, and the right end of the tension keel passes through the first constraint tube and is connected to the movable block.
[0008] Furthermore, one end of the catheter is connected to a negative pressure suction machine that provides negative pressure for suction.
[0009] Furthermore, a hinge plate is provided between the first constraint tube and the second constraint tube, with both ends of the hinge plate hinged to the second constraint tube and the first constraint tube, respectively.
[0010] Furthermore, the bent pipe is a flexible tube or a corrugated tube.
[0011] Compared with the prior art, the present invention has the following beneficial effects: This invention improves the accuracy of surgery by pushing the tension keel to bend it, thereby causing the suction tube to bend. The angle of the suction tube can be adjusted according to the degree of bending of the tension keel. Attached Figure Description

[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention. Example
[0014] This embodiment describes a suction device for spinal surgery, such as... Figures 1 to 5 As shown, it includes a bendable suction tube 1, a first constraint tube 3 is fixed on the outer wall of the suction tube 1, and a second constraint tube 2 is fixed on the suction tube 1 corresponding to the left end of the first constraint tube 3. The same tension keel 4 is independently installed in the first constraint tube 3 and the second constraint tube 2. The tension keel 4 is made of elastic material, and the left end of the tension keel 4 is fixed in the second constraint tube 2.
[0015] When in use, push the tension keel 4 to the left. With the left end of the tension keel 4 fixed, the pushing force causes the tension keel 4 to bend. Since the whole is bound by the second constraint tube 2 and the first constraint tube 3, the bending can only be released through the unbound section between the second constraint tube 2 and the first constraint tube 3, thereby causing the tension keel 4 to bend, and the bendable suction tube 1 to bend together, so that the suction tube 1 bends at different angles, thereby achieving the purpose of adjusting the suction angle of the suction tube 1.
[0016] like Figure 1 and Figure 2 As shown, the suction tube 1 includes a main tube 1.1, the left end of the main tube 1.1 is connected to a bendable tube 1.2, and the other end of the bend tube 1.2 is connected to a movable tube 1.3; the first constraint tube 3 is fixed on the main tube 1.1, and the second constraint tube 2 is fixed on the movable tube 1.3.
[0017] Based on the above description, pushing the tension keel 4 causes it to bend. The bending force is released between the second constraint tube 2 and the first constraint tube 3, causing the suction tube 1 to bend at the bend tube 1.2, and the angle between the movable tube 1.3 and the main tube 1.1 changes. As the force of pushing the tension keel 4 varies, the degree of bending of the bend tube 1.2 varies, and the included angle between the movable tube 1.3 and the main tube 1.1 varies, thereby achieving the purpose of adjusting the suction angle of the suction tube 1.
[0018] like Figure 5 As shown, a handle 7 is fixed to the right end of the main tube 1.1, and a conduit 6 is connected to the right side wall of the handle 7. A through hole is provided on the handle 7 to allow the conduit 6 to communicate with the main tube 1.1. One end of the conduit 6 is connected to a negative pressure suction machine that provides suction pressure. The negative pressure suction machine is an existing product commonly used in surgical septic tank cleaning. During use, negative pressure is provided by the machine and applied to the suction tube 1 to remove accumulated blood or tissue exudate.
[0019] The handle 7 is equipped with a movable block 5 that can slide left and right. The right end of the tensioning keel 4 passes through the first restraint tube 3 and is connected to the movable block 5. A groove is provided at the top of the handle 7, and a slider that slides left and right along the groove is fixed at the bottom of the movable block 5. In use, the movable block 5 is restricted to left and right movement by the cooperation of the groove and the slider. During operation, the doctor holds the handle 7 and pushes the movable block 5 to the left with his thumb to tighten the tensioning keel 4, thereby adjusting the angle of the movable tube 1.3.
[0020] The bending pipe 1.2 is a flexible hose or a corrugated pipe; during production, the bending pipe 1.2, as a bendable object, is made of flexible hose or corrugated pipe to achieve bending.
[0021] like Figure 2 and Figure 3As shown, a hinge plate 8 is provided between the first constraint tube 3 and the second constraint tube 2. The two ends of the hinge plate 8 are respectively hinged to the second constraint tube 2 and the first constraint tube 3. A first connecting block is fixed to the left end of the first constraint tube 3, and a second connecting block is fixed to the right end of the second constraint tube 2. The left and right ends of the hinge plate 8 are respectively hinged to the first and second connecting blocks, allowing the second constraint tube 2 and the first constraint tube 3 to swing only up and down, thus limiting the movement of the movable tube 1.3 to up and down. This prevents the tension keel 4 from pushing the movable tube 1.3, which would cause the swing direction of the movable tube 1.3 to become unstable.
[0022] During production, the hinge plate 8 is provided with two sets, front and rear, to make the hinge between the second constraint tube 2 and the first constraint tube 3 more stable.
[0023] In actual use, the doctor pushes the movable block 5 to bend the tension keel 4, controlling the bend between the second constraint tube 2 and the first constraint tube 3. By varying the degree of bending of the tension keel 4, the doctor can adjust the swing angle of the movable tube 1.3, thereby changing the suction angle of the suction tube 1 and improving the precision of the surgical procedure to some extent. Furthermore, this product is easy to operate.
