Description

TECHNICAL FIELD

[0001] The present application relates to a swallowing-preventing suction device for minimally invasive surgery, in particular to a swallowing-preventing suction device for ultrasound-guided thyroid minimally invasive surgery. BACKGROUND

[0002] Ultrasound-guided thyroid minimally invasive surgery includes thyroid puncture, thyroid ablation, thyroid sclerotherapy, etc. During the operation, the needle is inserted into the target lesion of the thyroid under the guidance of ultrasound to diagnose or treat it. The above process requires the high cooperation of the patient. Specifically, the thyroid is attached to the lateral surface of the lower larynx and the upper trachea, and will move up and down with the swallowing action. During the operation, the patient may not be able to control swallowing due to nervousness, and if the thyroid moves up and down, the needle may be displaced, greatly increasing the risk of damaging important blood vessels, nerves, and trachea around. The similar devices on the market are more commonly used in stomatology, which are generally used by doctors to use a negative pressure device to suck oral secretions and blood, without considering swallowing. There are also some oral saliva suction devices, such as a self-cross-ear oral negative pressure suction device (CN108785765A), which is used by the patient to suck saliva by himself, but there is no swallowing-preventing device.

[0003] In order to solve the above-mentioned design problems, the present application provides a swallowing-preventing suction device for ultrasound-guided thyroid minimally invasive surgery, so as to not only achieve the prevention of swallowing action in the patient's mouth during the operation, but also to timely suck the saliva produced in the patient's mouth, avoid the saliva stimulation to cause the swallowing action, increase the comfort of the patient, and improve the safety of the operation process.

DETAILED DESCRIPTION

[0024] like Figures 1-5 As shown, the present invention discloses an anti-swallowing suction device for ultrasound-guided minimally invasive thyroid surgery, comprising a main support tube, a sliding inner tube 2, an engaging mechanism 3, an outer capsule 4, a negative pressure suction system 5, an anti-swallowing pressure-blocking component 6 and a tongue-pressing and liquid-sucking component 7. The main support tube is a cylindrical structure with a horizontal section on the upper part, and a deflected top pressure bag cover 11 is hinged on the right edge of the upper part of the main support tube. Specifically, a tension spring component 112 is embedded in the bottom of the top pressure bag cover 11, and the top pressure bag cover 11 is buckled on the upper part of the main support tube by the action of the tension spring component 112. The upper end of the top pressure bag cover 11 is ellipsoidal and is fitted with a silicone pad 111.

[0025] The sliding inner cylinder 2 is slidably inserted into the inner side of the cylinder of the main support cylinder, and the left end of the sliding inner cylinder 2 is fixedly connected to the outward-extending auxiliary handle 21. The outer side of the sliding inner cylinder 2 is provided with an adjusting slip ring 33, and the adjusting slip ring 33 includes a locking pin assembly 34 for locking the sliding. The upper part of the adjusting slip ring 33 is connected to the left end of the top pressure bag cover 11 through the bite mechanism 3, and the lower part of the adjusting slip ring 33 is connected to the left end of the main support cylinder through the bite mechanism 3. The bite mechanism 3 includes a bite deflection plate 31 and a support deflection plate 32. One end of the support deflection plate 32 is hinged to the inner side of the middle part of the bite deflection plate 31, and the other end of the support deflection plate 32 is hinged to the adjusting slip ring 33. The hinged cross-sectional structure of the bite deflection plate 31 and the support deflection plate 32 is in the shape of an "入" character, and a silicone bite block with a groove is provided on the outer side of the end of the bite deflection plate 31. After the teeth engage, the rear end of the upper occlusal deflector plate 31 rises, driving the pressure capsule cover 11 to flip outward and lift. The pressure capsule cover 11 presses against the upper jaw and, together with the lower attached tongue depressor 71, secures the device in the oral cavity. Simultaneously, due to relative motion, while the main support cylinder is relatively stationary, the sliding inner cylinder 2 is pushed outward by the support deflector plate 32. This, in conjunction with the lower support deflector plate 32, pushes the sliding inner cylinder 2 outward, thereby fine-tuning the occlusal position and returning the rear anti-swallowing block to its original position. In practice, the upper occlusal deflector plate 31 deflects more, as part of its mechanical movement, in addition to pushing the sliding inner cylinder 2 outward, also translates into eversion of the pressure capsule cover 11. Through this top-pressing, bottom-suctioning structure, the present invention achieves multiple functions without the need for separate oral fixation and occlusal adjustment devices, resulting in a compact structure and effective space savings.

[0026] The right end of the sliding inner cylinder 2 is provided with a fixed retaining ring for limiting the position. The outer sides of the engaging mechanism 3 and the top pressure bag cover 11 are sealed and wrapped between the adjusting sliding ring 33 and the fixed retaining ring through the outer bag body 4. The sealing structure formed by the outer bag body 4 isolates the moving structure and other parts that are difficult to clean, thereby achieving a modular disassembly and washing effect, and at the same time can effectively prevent the physical structure from touching the inside of the oral cavity, reducing the irritation of foreign objects.

[0027] The right side of the fixed baffle ring is fixedly connected with an anti-swallowing pressure-blocking component for blocking saliva from entering the oropharynx. The anti-swallowing pressure-blocking component includes a connecting hose 61 and a suction cochlear head 62. The diameter of the connecting hose 61 is gradually changed, and the elasticity of the connecting hose 61 itself can naturally press the suction cochlear head 62 downward, which not only effectively blocks the saliva from the tongue from flowing into the throat, but also the snail-shaped extension structure can achieve compact contraction of the structure, avoiding the conventional structure bulging outward or saliva flowing into the pharyngeal nerve to stimulate the swallowing action. The suction cochlear head 62 is fixedly connected to the outer end of the connecting hose 61. The suction volute 62 includes a silicone transition piece 621 and an annular tube 622. The upper end of the silicone transition piece 621 is fixedly connected to the outer end of the connecting hose 61, and the left side of the silicone transition piece 621 is fixedly attached to the annular tube 622 to form an overall volute cross-section. The above-mentioned annular tube 622 is closed at both ends, and the upper and lower parts of the annular tube 622 are provided with through-holes. The lower left part of the annular tube 622 is provided with an installation slot, and the seamless plug in the installation slot is equipped with a hollow plastic tile 622a, and the plastic tile 622a is provided with a through-hole for the suction branch pipe 531 to penetrate.

[0028] The bottom of the main support tube is provided with a tongue depressor and liquid suction assembly 7, which includes a base plate 72, an attached tongue depressor 71 and a side sealing capsule 73. A support column 721 is installed at the bottom of the base plate 72. A divergent branch channel is provided in the middle of the support column 721. The top of the branch channel is connected to the suction branch 531. The outer end of the branch channel is connected to the ball-shaped liquid suction head 8 through a tube body. The support column 721 is connected to the attached tongue depressor 71 through a universal head. The outer edge of the attached tongue depressor 71 is sealed and connected to the edge of the base plate 72 through the side sealing capsule 73. The edge of the attached tongue depressor 71 is dispersedly provided with mounting ball heads. The mounting ball heads are provided with an oblique socket that passes through the inside and outside of the capsule cavity. The ball-shaped liquid suction head 8 is fixedly inserted into the oblique socket. The ball-enclosed liquid suction head 8 comprises an outer ball 81, an inner ball 82, and a plug-in tube. The outer ball 81 and inner ball 82 are concentrically nested and connected via the plug-in tube. The outer ball 81 is connected to the outer wall of the plug-in tube. The outer ball 81 is a spherical structure with a hollow plastic mesh. The inner ball 82 is connected to the end of the plug-in tube to achieve indirect liquid suction. The inner ball 82 has a liquid suction cutout at its bottom. The tongue-pressing liquid suction assembly 7 not only effectively adheres to the tongue, providing bottom support for the movement of the upper mechanism, but also its own ball-enclosed liquid suction head 8 effectively and disperses saliva from the edges and crevices of the tongue, cleverly adapting to the distribution characteristics of saliva. At the same time, the dual-ball liquid suction structure prevents clogging of the suction holes or damage to the oral mucosa due to suction pressure. The present invention performs liquid suction through a two-stage structure, effectively drawing saliva and preventing saliva from flowing into the throat, avoiding irritation that may cause swallowing. The universal attachment structure and the snail-shaped spring-loaded structure also achieve the comfort requirements of the above process.

[0029] In addition, the present invention is also provided with a negative pressure suction system 5, which includes a negative pressure drainage bottle 51, a negative pressure device 52 and a suction tube 53. The suction tube 53 draws saliva to the negative pressure drainage bottle 51 through the negative pressure device 52. The suction tube 53 is provided with a drainage adjustment switch 54. The end of the suction tube 53 is provided with a branched suction branch 531. The suction branch 531 is used to connect the tongue depressor and liquid suction component 7 and the anti-swallowing pressure blocking component to suction saliva.

[0030] In actual use, the lower part of the present invention is used to absorb saliva to prevent sputum stimulation from causing swallowing, and the upper part is used to press and fix the upper jaw of the mouth. The pressure adjustment structure can not only adjust the outer diameter to adapt to the mouth size of different patients, but also allow the patient to relax during the operation, thereby reducing swallowing movements caused by tension and other reasons. After the device is placed in the mouth through the auxiliary handle 21, the upper and lower teeth bite accordingly. With the cooperation of the lower structure, the upper jaw is pressed to achieve the fixation of the device, while the sliding inner cylinder 2 is pushed outward. The rear suction snail head 62 blocks the saliva in the back of the mouth and absorbs saliva at the same time to avoid discomfort. The front attached tongue depressor 71 can adapt to the slight movement of the tongue and continuously absorb saliva at the edge of the tongue. The distributed double-ball structure has high suction efficiency and avoids the damage to the oral mucosa caused by negative pressure.

[0031] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
