Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a foldable oral surgical suction tube. Background Technology

[0002] The oral cavity is the starting point of the digestive tract. It connects to the outside world through the mouth fissure in the front and continues to the pharynx through the pharyngeal isthmus in the back. The oral cavity contains organs such as teeth and tongue. The anterior wall of the oral cavity is the lips, the lateral walls are the cheeks (including the opening of the parotid duct), the roof is the palate, and the floor of the oral cavity contains mucosa, muscles, and salivary glands. During oral surgery, in order to avoid saliva from obstructing the operation, a vacuum pump is used to suction out the saliva produced in the oral cavity.

[0003] During oral surgery, due to the limited space and complex structure of the oral cavity, the existing suction tube angle and handle support position are not flexible enough. Doctors find it difficult to adjust the angle of the suction tube according to actual needs during the operation, resulting in a limited surgical field of vision, affecting the accuracy and efficiency of the operation. Secondly, the suction tube tip design is not reasonable enough, which often causes great irritation and damage to the oral mucosa, reducing patient comfort.

[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed a foldable oral surgical suction tube. Utility Model Content

[0005] The purpose of this invention is to provide a foldable oral surgical suction tube to solve the problems mentioned in the background art, such as the lack of flexibility in adjusting the angle of the suction tube and the position of the handle support, which leads to a limited surgical field of vision, affecting the accuracy and efficiency of the surgery, and the unreasonable design of the suction tube tip, which leads to damage to the oral mucosa and reduces patient comfort.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a foldable oral surgical suction tube, comprising a first suction tube, one end of which is fixed with a corrugated tube, one end of which is a second suction tube, and one end of which is provided with a suction head connected by a threaded assembly, wherein the suction head has a through hole inside.

[0007] A first support ring is fixed to the outer wall of the first suction tube. A movable rod connected to the upper end of the first support ring is provided through an adjustment component. A volume control shell is fixed inside the first suction tube. A volume control plate connected to the first suction tube through a lifting component is provided inside the first volume control shell. A limit ring is fixed to the outer wall of the first suction tube. A handle bracket is attached to the inner wall of the limit ring. A locking component for fixing is provided inside the handle bracket.

[0008] Furthermore, the threaded assembly includes a threaded tube with an internal threaded connection at one end of the second suction tube, and the suction head is fixedly connected to one end of the threaded tube, and the suction head has an arc-shaped structure.

[0009] Furthermore, the adjustment assembly includes a slide rail bracket fixed to the upper end of the first support ring, a slider slidably connected to the inner wall of the slide rail bracket, a first screw rotatably connected to the inside of the slide rail bracket, the slider and the first screw being threadedly connected, and a movable rod located at the upper end of the slider being rotatably connected via a rotating shaft.

[0010] Furthermore, a second support ring is fixed to the outer wall of the second suction tube, and a support block is fixed to the upper end of the second support ring. The upper end of the support block is rotatably connected to the other end of the movable rod through a rotating shaft.

[0011] Furthermore, the locking assembly includes a locking bolt with internal threaded connection to the handle bracket, and a fixing ring is provided on the side wall of the handle bracket away from the limiting ring, and the fixing ring is fixedly connected to the first suction tube, and the fixing ring has a threaded hole inside.

[0012] Furthermore, a miniature vacuum pump is fixed to the end of the first suction tube away from the corrugated tube, and a discharge tube is fixed to the lower end of the first suction tube, with a collection shell connected to the internal thread of the discharge tube.

[0013] Furthermore, the lifting assembly includes a second screw threadedly connected to the upper end of the control housing, the control plate being slidably connected inside the control housing, and the upper end of the control plate being rotatably connected to the second screw.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] Firstly, this invention utilizes the rotation of a first screw to allow a slider to slide on a slide rail support. The two ends of a movable rod are rotatably connected to a support block and slider on the second suction tube via a rotating shaft. When the slider slides along the right side of the slide rail support, the movable rod pulls the support block, allowing the second suction tube to be folded and its angle adjusted via a corrugated tube and the first suction tube. This enables the suction tube to flexibly adjust its angle and position during surgery, adapting to the complex and narrow surgical environment of the oral cavity. The surgeon can easily adjust the angle of the suction tube according to the needs of the surgery, thereby more accurately removing liquids and debris from the oral cavity, maintaining a clear surgical field. The foldable suction tube design better conforms to the patient's oral structure, making the operation more convenient.

[0016] Secondly, the second suction tube of this invention is placed inside the oral cavity, and then the arc-shaped suction head contacts the oral mucosa to aspirate oral fluid, reducing damage to the oral mucosa. The through-hole on the suction head also reduces the irritation to the oral mucosa caused by negative pressure, thus improving patient comfort. Finally, the suction head is detachable from the second suction tube through a threaded tube, making it easier to clean, disinfect, and replace the suction tube after surgery.

[0017] Thirdly, the handle bracket of this utility model is rotatable and adjustable along the outer wall of the first suction tube between the limiting ring and the fixing ring. Then, a locking bolt passes through the threaded hole on the fixed ring and locks the handle bracket in place, thus fixing the handle bracket after it has been adjusted along the outer wall of the first suction tube. This improves the flexibility of the surgical operation, allowing the doctor to easily adjust the angle and position of the suction tube as needed during the operation. For situations where the oral cavity space is limited and the surgical site may be located at different positions and depths, rotating the handle bracket allows the doctor to more easily reach the surgical area and perform precise suction operations. Then, rotating the second screw drives the volume control plate to slide inside the volume control shell, controlling the flow rate between the micro vacuum pump and the first suction tube. This avoids excessive negative pressure that could damage the oral mucosa. The doctor can adjust the suction level to the most suitable degree according to the surgical needs, effectively removing liquids and debris from the oral cavity without damaging the oral mucosa due to excessive negative pressure. This makes the surgical operation more flexible and convenient. Attached Figure Description

[0026] In a preferred embodiment, the threaded assembly includes a threaded tube 202 internally threaded to one end of the second suction tube 201, and a suction head 203 fixedly connected to one end of the threaded tube 202. The suction head 203 has an arc-shaped structure. The second suction tube 201 is placed inside the oral cavity, and then the arc-shaped suction head 203 contacts the oral mucosa to suction the oral fluid, reducing the harm to the oral mucosa. The through hole 204 on the suction head 203 reduces the irritation to the oral mucosa when there is negative pressure, improving the patient's comfort. Finally, the suction head 203 is detachable from the second suction tube 201 through the threaded tube 202, making it easier to clean, disinfect, and replace the suction tube after surgery.

[0027] In a preferred embodiment, the adjusting assembly includes a slide rail bracket 301 fixed to the upper end of the first support ring 3. A slider 303 is slidably connected to the inner wall of the slide rail bracket 301. A first screw 302 is rotatably connected inside the slide rail bracket 301. The slider 303 and the first screw 302 are threadedly connected. A movable rod 304 is located above the slider 303 and rotatably connected via a rotating shaft. A second support ring 305 is fixed to the outer wall of the second suction tube 201. A support block 306 is fixed to the upper end of the second support ring 305. The upper end of the support block 306 is rotatably connected to the other end of the movable rod 304 via a rotating shaft. By adjusting the first screw 302... 2. The slider 303 rotates on the slide rail bracket 301 via the first screw 302. The support block 306 is pulled by the movable rod 304, allowing the second suction tube 201 to be folded and angled with the first suction tube 1 via the corrugated tube 2. This allows the suction tube to be flexibly adjusted in angle and position during the operation, adapting to the complex and narrow surgical environment inside the mouth. Doctors can easily adjust the angle of the suction tube according to the needs of the operation, thereby more accurately removing liquids and residues from the mouth and maintaining a clear surgical field. The foldable suction tube design can better fit the patient's oral structure, making the surgical operation more flexible and convenient.

[0028] In a preferred embodiment, a miniature vacuum pump 6 is fixed to the end of the first suction tube 1 away from the bellows 2. The locking assembly includes a locking bolt 402 threaded inside the handle bracket 401. A fixing ring 403 is provided on the side wall of the handle bracket 401 away from the limiting ring 4, and the fixing ring 403 is fixedly connected to the first suction tube 1. A threaded hole 404 is provided inside the fixing ring 403. The handle bracket 401 can be rotated and adjusted along the outer wall of the first suction tube 1 between the limiting ring 4 and the fixing ring 403. Then, the locking bolt 402 passes through the threaded hole 404 on the fixing ring 403 to lock the handle bracket 401, thereby fixing the handle bracket 401 after it is rotated and adjusted along the outer wall of the first suction tube 1. This improves the flexibility of the surgical operation and allows the doctor to easily adjust the angle and position of the suction tube as needed during the operation. For the limited space in the oral cavity and the surgical site located at different positions and depths, by rotating the handle bracket 401, the doctor can more easily reach the surgical area and perform precise suction operations.

[0029] In a preferred embodiment, the lower end of the first suction tube 1 is fixed with a discharge tube 7, and the discharge tube 7 is internally threaded with a collection shell 701. A miniature vacuum pump 6 is installed to generate negative pressure on the suction tube, which adsorbs the liquid and then flows into the collection shell below the discharge tube 7. The collection shell 701 and the discharge tube 7 can be threadedly disassembled for easy cleaning.

[0030] In a preferred embodiment, the lifting assembly includes a second screw 501 threadedly connected to the upper end of the volume control housing 5, and a volume control plate 502 slidably connected inside the volume control housing 5. The upper end of the volume control plate 502 is rotatably connected to the second screw 501. By rotating the second screw 501, the volume control plate 502 slides inside the volume control housing 5, controlling the flow rate between the micro vacuum pump 6 and the first suction tube 1. This avoids excessive negative pressure that could damage the oral mucosa. The doctor can adjust the suction level to the most suitable level according to the surgical needs, effectively removing liquids and debris from the mouth without damaging the oral mucosa due to excessive negative pressure. The doctor can adjust the suction level at any time according to the surgical needs, making the surgical operation more flexible and convenient.

[0031] The micro vacuum pump 6 mentioned above, model PCF5015N, is existing technology and will not be elaborated further.

[0032] Working principle: The miniature vacuum pump 6 creates negative pressure within the suction tube, drawing in liquid which then flows into the collection shell below the discharge pipe 7. The second suction tube 201 is then placed inside the oral cavity, and the arc-shaped suction head 203 contacts the oral mucosa to absorb oral fluid, minimizing harm to the mucosa. Rotation of the first screw 302 causes the slider 303 to slide on the slide rail bracket 301. The movable rod 304 pulls the support block 306, allowing the second suction tube 201 to be folded at an adjustable angle with the first suction tube 1 via the corrugated pipe 2, thus facilitating suction. During the operation, the tube can be flexibly adjusted in angle and position. The handle bracket 401 can be rotated and adjusted along the outer wall of the first suction tube 1 between the limiting ring 4 and the fixing ring 403. Then, the locking bolt 402 passes through the threaded hole 404 on the fixed ring 403 to lock the handle bracket 401, thereby fixing the handle bracket 401 after it is rotated and adjusted along the outer wall of the first suction tube 1, which improves the flexibility of the surgical operation. At the same time, by rotating the second screw 501, the volume control plate 502 slides inside the volume control shell 5, which controls the flow rate of the micro vacuum pump 6 and the first suction tube 1, avoiding excessive negative pressure that could damage the oral mucosa.

[0033] This is how this type of foldable oral surgical suction tube works.
