Description

Technical Field

[0001] The invention relates to an anti-swallowing suction device for minimally invasive surgery, and in particular to an anti-swallowing suction device for minimally invasive thyroid surgery under ultrasound guidance. Background Art

[0002] Ultrasound-guided minimally invasive thyroid surgery includes thyroid puncture, thyroid ablation, thyroid sclerotherapy, etc. During the operation, an ultrasound-guided operating needle is inserted into the target thyroid lesion to diagnose or treat it, and the above process requires a high degree of cooperation from the patient. Specifically, the thyroid gland is attached to the outer side of the lower larynx and the upper trachea, and will move up and down with the swallowing action. During the operation, the patient will be unable to control swallowing due to tension. If the thyroid gland slides up and down, the operating needle may shift, greatly increasing the risk of damaging important peripheral blood vessels, nerves, and trachea. Similar devices on the market are currently widely used in stomatology. Doctors generally use a negative pressure device to suck away oral secretions and blood, without special swallowing considerations. There are also some oral saliva suction devices, such as a self-service trans-ear oral negative pressure suction device (CN108785765A), which allows patients to suck away saliva on their own, but there is no anti-swallowing device.

[0003] In order to solve the above-mentioned design deficiencies, the present invention provides an anti-swallowing suction device for ultrasound-guided minimally invasive thyroid surgery, which can not only realize the anti-swallowing action of the patient's mouth during the operation, but also can timely attract the saliva produced in the patient's mouth to avoid swallowing action caused by saliva stimulation, increase the patient's comfort, and improve the safety of the operation process. Summary of the invention

[0008] Furthermore, the hinged cross-sectional structure of the engaging deflection plate and the supporting deflection plate is in the shape of an “In”, and a silicone engaging block with a groove is provided on the outer side of the end of the engaging deflection plate.

[0009] Furthermore, the anti-swallowing pressure-blocking component includes a connecting hose and a suction volute. The diameter of the connecting hose is gradual.

DETAILED DESCRIPTION

[0024] like Figure 1-5 As shown, the present invention discloses an anti-swallowing suction device for minimally invasive thyroid surgery under ultrasound guidance, 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 block component 6 and a tongue depressing and liquid suction 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 through the action of the tension spring component 112. The upper end of the top pressure bag cover 11 is in an ellipsoidal shape and is fitted with a silicone pad 111.

[0025] The sliding inner cylinder 2 is slidably inserted inside the cylinder of the main support cylinder. The left end of the sliding inner cylinder 2 is fixedly connected with an extended auxiliary handle 21. An adjusting sliding ring 33 is sleeved outside the sliding inner cylinder 2. The adjusting sliding ring 33 includes a set screw component 34 for locking the sliding. The upper part of the adjusting sliding ring 33 is connected to the left end of the pressing bladder cover 11 through a biting mechanism 3. The lower part of the adjusting sliding ring 33 is connected to the left end of the main support cylinder through the biting mechanism 3. The biting mechanism 3 includes a biting deflection plate 31 and a supporting deflection plate 32. One end of the supporting deflection plate 32 is hinged inside the middle of the biting deflection plate 31, and the other end of the supporting deflection plate 32 is hinged on the adjusting sliding ring 33. The hinged cross-section structure of the biting deflection plate 31 and the supporting deflection plate 32 is in the shape of "入". The outer side of the end of the biting deflection plate 31 is provided with a silica gel biting block with a groove. After tooth occlusion, the rear end of the upper biting deflection plate 31 is lifted, which will drive the pressing bladder cover 11 to turn outwards and lift up. The pressing bladder cover 11 presses against the upper jaw and, at the same time as the lower attaching tongue depressor 71, realizes the fixation of the device in the oral cavity. At the same time, due to the relative movement relationship, when the main support cylinder is relatively stationary, the sliding inner cylinder 2 is pushed out by the supporting deflection plate 32 and, with the cooperation of the lower supporting deflection plate 32, jointly pushes out the sliding inner cylinder 2, so as to realize the fine adjustment of the tooth occlusion position and the anti-swallowing blocking and resetting at the rear. In fact, the deflection degree of the upper biting deflection plate 31 is larger, because part of its mechanism movement, in addition to pushing out the sliding inner cylinder 2, is also converted into the outwards displacement of the pressing bladder cover 11. Through the above-mentioned structure of pressing from above and sucking from below, the present invention can realize various functions without a separate oral fixation and occlusion adjustment device, and the structure is compact, effectively saving space.

[0026] A fixed retaining ring for limiting is provided at the right end of the sliding inner cylinder 2. The outer sides of the biting mechanism 3 and the pressing bladder cover 11 are hermetically wrapped between the adjusting sliding ring 33 and the fixed retaining ring through an outer wrapping body 4. Through the sealing structure formed by the outer wrapping body 4, the moving structures and other parts that are not easy to clean are isolated, realizing the modular disassembly and washing use effect, and at the same time can effectively avoid the physical structure from touching the inner side of the oral cavity and reduce the foreign body irritation.

[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 of 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 middle 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 two ends of the annular tube 622 are closed, and the upper and lower parts of the annular tube 622 are both provided with through openings. The lower left side of the annular tube 622 is provided with an installation groove, and a hollow plastic tile 622a is installed in the seamless plug in the installation groove. The plastic tile 622a is provided with a through opening for the suction branch pipe 531 to penetrate.

[0028] The bottom of the main support tube is provided with a tongue depressor and liquid-absorbing 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 sleeve ball liquid-absorbing head 8 through the 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, and the mounting ball heads are provided with an oblique insertion hole that passes through the inside and outside of the capsule cavity. The sleeve ball liquid-absorbing head 8 is fixedly inserted in the oblique insertion hole. The ball-covered liquid suction head 8 includes an outer tennis ball 81, an inner suction ball 82 and a column tube. The outer tennis ball 81 and the inner suction ball 82 are connected concentrically through the column tube. The outer tennis ball 81 is connected to the outer wall of the column tube. The outer tennis ball 81 is a plastic hollow mesh spherical structure. The inner suction ball 82 is connected to the end of the column tube to achieve indirect liquid suction. The bottom of the inner suction ball 82 is provided with a liquid suction cutout. The tongue-pressing liquid suction component 7 can not only effectively adhere to the tongue and provide bottom support for the movement of the upper mechanism, but also its own ball-covered liquid suction head 8 can effectively disperse the saliva memory of the gap along the edge of the tongue, cleverly adapting to the distribution characteristics of saliva. At the same time, the double-ball liquid suction structure can prevent the suction hole from being blocked or the oral mucosa from being damaged by the suction pressure. The present invention performs liquid suction through the front and rear two-stage structures, which can effectively absorb saliva and block saliva from flowing into the throat, avoiding stimulation and causing swallowing consequences. At the same time, it is provided with a universal attachment structure and a snail-shaped elastic pressure structure to 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 sucks 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 depressing and liquid aspiration 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 swallowing caused by sputum stimulation, and the upper part is used to press and fix the upper jaw of the oral cavity. The pressing 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 the swallowing action caused by tension and other reasons. After the device is placed in the oral cavity 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 fix the device, and at the same time, the sliding inner cylinder 2 is pushed outward, and the rear suction snail head 62 blocks the saliva in the back of the oral cavity and absorbs saliva at the same time to avoid discomfort, while the front attached tongue depressor 71 can adapt to the tongue micro-movement and continuously absorb saliva at the edge of the tongue. The distributed double-ball structure has high suction efficiency and avoids the suction damage to the oral mucosa by negative pressure.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement and improvement made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
