[0032] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Embodiment 1: In view of the problem that the negative pressure suction structure and the position of the endoscope probing into the oral cavity cannot be accurately controlled, resulting in the frequent extension and retraction of the negative pressure suction end during foreign body suction, which affects the suction accuracy, the following technical solution is proposed:

[0034] Reference Figure 1 - Fig. 9 As shown, in this embodiment, an oral clinical care foreign body suction assembly comprises a holding rod 1 and a connecting seat 5 connected to each other, the connecting seat 5 is arranged at the bottom of the holding rod 1 and has fork plates 8 installed on both sides, and a positioning assembly 3 is installed on the inner sides of a pair of fork plates 8, and the positioning assembly 3 comprises a mouth support ring 31 that is clamped with the corners of the patient's mouth on both sides;

[0035] A pneumatic extraction assembly 4 for oral foreign body suction is installed through the middle of the connecting seat 5. The pneumatic extraction assembly 4 includes a main suction pipe 41 plugged into the bottom of the gripping rod 1. A suction head 42 with an elliptical cross section is installed at the front end of the main suction pipe 41. A fish mouth head 1 43 and a fish mouth head 2 44 are installed vertically on the suction head 42. The fish mouth head 1 43, the fish mouth head 2 44 and the main suction pipe 41 are all connected to a pneumatic suction source. An endoscope body 18 is embedded in the middle of the front end of the suction head 42.

[0036] Reference Figure 8 and Fig. 9As shown, the main suction pipe 41 is also inserted with a trachea 16 and a trachea 2 17 connected in parallel, the trachea 16 extends to the interior of the suction head 42 and is installed with a shrinking and expanding capsule 14, the trachea 2 17 extends to the interior of the suction head 42 and is installed with a shrinking and expanding capsule 2 15, the shrinking and expanding capsule 14 corresponds to and is embedded in the fish mouth head 1 43, a pair of shrinking and expanding capsules 2 15 corresponds to and is embedded in a pair of fish mouth heads 2 44, and when the shrinking and expanding capsules 14 and 15 are expanded, they are respectively filled into the fish mouth head 1 43 and the fish mouth head 2 44 to form a seal;

[0037] Reference Figure 3 - Figure 5 As shown, the lower ends of the gripping rod 1 and the connecting seat 5 are commonly plugged with a fixed flat ring 6, a rotating rod 45 is rotatably installed in the middle of the fixed flat ring 6, and a sleeve 7 for inserting the main suction pipe 41 is commonly installed between the rotating rods 45;

[0038] A control module is connected to the endoscope body 18, and the control module has a built-in image acquisition unit, a positioning analysis unit, an absorption control unit, an alarm reminder unit and a processor that are communicatively connected, wherein the alarm reminder unit is communicatively connected to a speaker arranged on the gripping rod 1;

[0039] The image acquisition unit is used to take pictures of the probing pictures during oral care, and send the taken pictures to the positioning analysis unit via the processor to obtain evaluation information, compare and analyze the evaluation information with the picture information preset in the processor, output the side suction signal and the top suction signal and send them to the suction control unit;

[0040] When the suction control unit receives the side suction signal, it sends the side suction signal to the air pump connected to the trachea 16, and the air pump inflates the trachea 16 and drives the shrinking and expanding capsule 14 to expand. The shrinking and expanding capsule 14 expands to the fish mouth head 1 43, forming a channel in the suction head 42 where only the fish mouth head 2 44 is open. At this time, the pneumatic suction device completes the suction of the suction head 42 and the fish mouth head 2 44 through the main suction pipe 41, so that the foreign matter on the oral cavity wall is sucked through the fish mouth head 2 44 and adsorbed to the outside of the channel of the fish mouth head 2 44;

[0041] When the suction control unit receives the top suction signal, it sends the top suction signal to the air pump connected to the trachea 17, and the air pump inflates the trachea 17 and drives the expansion capsule 15 to expand. The expansion capsule 15 expands to the fish mouth head 44, forming a channel in the suction head 42 where only the fish mouth head 43 is open. At this time, the pneumatic suction device completes the suction of the suction head 42 and the fish mouth head 43 through the main suction pipe 41, so that the foreign matter on the oral cavity wall is sucked through the fish mouth head 43 and adsorbed to the outside of the channel of the fish mouth head 43;

[0042] It should be noted that: a support groove 32 corresponding to the corner of the mouth is provided on the outer side of the mouth support ring 31; a positioning rod 33 corresponding to the positioning hole 10 on the fork plate 8 is installed in the middle of the front side of the mouth support ring 31; the positioning rod 33 extends to the front side of the fork plate 8 and is sleeved with a positioning nut 34; a receiving groove 35 is commonly connected between the lower ends of a pair of mouth support rings 31, and the receiving groove 35 is used to absorb foreign matter.

[0043] When the image acquisition unit is used to shoot the intraoral probe image, if the side suction signal and the top suction signal are generated at the same time, the side suction signal has a higher priority than the top suction signal, and after the side suction and top suction actions are completed, the following actions need to be performed manually:

[0044] No matter after the side suction or top suction is completed, the pneumatic suction device does not stop suction. After the side suction is completed, a side suction completion signal will be generated and sent to the alarm reminder unit. The alarm reminder unit emits a short beeping sound through the speaker to remind the nursing staff to pull the main suction tube 41 outward until the suction head 42 is vertically aligned with the receiving groove 35. At this time, the pneumatic suction device stops suction, and the air pump also stops inflating, so that the foreign matter outside the fish mouth head 44 is separated from the suction of the suction head 42 and falls into the receiving groove 35;

[0045] Similarly, after the top suction is completed, a top suction completion signal will be generated and sent to the alarm reminder unit. The alarm reminder unit will emit a continuous dripping sound through the speaker to remind the nursing staff to pull the main suction tube 41 outward until the suction head 42 is vertically aligned with the receiving groove 35. At this time, the pneumatic suction device stops suction and the air pump also stops inflating. Then, the foreign matter outside the fish mouth head 43 will be separated from the adsorption of the suction head 42 and fall into the receiving groove 35. The foreign matter that falls into the receiving groove 35 will be taken out after the nursing is completed.

[0046] Basic principle: The principle of suctioning foreign bodies in the oral cavity by pneumatic suction in the present invention is basically similar to the principle of conventional suctioning foreign bodies by relying on a negative pressure suction structure. The differences are as follows: on the one hand, the position of the foreign body before suction is guided and positioned by an endoscope, so that the negative pressure suction end and the position of the foreign body correspond precisely to achieve the purpose of precise control of suction; on the other hand, through a double suction component based on pneumatic suction, combined with an intelligent control system after detecting the position, side suction and top suction or a combination of the two are selected to complete the precise suction of foreign bodies at different positions in the oral cavity, thereby avoiding the frequent extension and retraction of the negative pressure suction end which affects the accuracy of suction.

[0047] Embodiment 2: This embodiment further optimizes the positioning structure of Embodiment 1 during pneumatic suction:

[0048] Reference Figure 4 and Figure 5As shown, an angle disk 11 is installed on the upper side of the front end of the fixed flat ring 6, and an angle line 12 is opened on the angle disk 11. A marking line 13 aligned with the angle line 12 is opened on the middle upper side of the outer ring side of the sleeve 7. The main suction pipe 41 is a transparent structure and a scale line is printed on the upper end of the outer ring side. The setting of the angle line 12, when the main suction pipe 41 is pushed inward, the scale line on the main suction pipe 41 is continuously immersed in the sleeve 7, and the inward pushing distance of the main suction pipe 41 is obtained. When the foreign body in the oral cavity is sucked sideways or top, the current deflection angle of the main suction pipe 41 is recorded, that is, the left and right deflection positions are known through the deflection angle of the marking line 13 on the main suction pipe 41 at the angle disk 11, which is convenient for the precise correspondence of the anti-inflammatory treatment position when the subsequent anti-inflammatory treatment of the affected area is carried out;

[0049] Reference Figure 1 and Figure 2 As shown, the ends of a pair of fork plates 8 are commonly connected with a strap 2, and the other ends of the fork plates 8 are connected with a soft connecting block 9 connected to the connecting seat 5. The strap 2 is an elastic band. When foreign matter is sucked out during oral care, the strap 2 is firstly tied to the head and the support groove 32 on the mouth support ring 31 corresponds to the corner of the mouth. At this time, the position of the positioning rod 33 in the positioning hole 10 is adjusted so that the mouth support rings 31 on both sides completely expand the corner of the mouth through the support groove 32, thereby exposing the oral cavity. When foreign matter is sucked out of the oral cavity, the main suction pipe 41 and the sleeve 7 drive the connecting seat 5 to shake under the action of the soft connecting block 9, so as to prevent the frequent shaking from causing unstable fixation and improve the accuracy of oral foreign matter suction.

[0050] Embodiment 3: This embodiment combines Embodiment 1 and Embodiment 2 to form the following operation steps:

[0051] S1: Installation: First, tie the strap 2 to the head and match the support grooves 32 on the mouth support ring 31 to the corners of the mouth. At this time, adjust the position of the positioning rod 33 in the positioning hole 10 so that the mouth support rings 31 on both sides can fully expand the corners of the mouth through the support grooves 32, thereby revealing the oral cavity;

[0052] S2: suction: the endoscope body 18 is used to determine the position of the foreign body, and the control module is used to select the side suction or top suction of the foreign body, and the fish mouth head 1 43 and the fish mouth head 2 44 are selected for suction by the expansion of the shrinking and expanding capsule 1 14 and the shrinking and expanding capsule 2 15, so as to finally realize the suction of the foreign body on the side or top surface of the oral cavity;

[0053] S3: Collection: After the foreign matter is sucked, the alarm reminder unit in the control module stops the different suction modes, and accurately controls the foreign matter to fall into the receiving groove 35 to complete the collection;

[0054] S4: Positioning: In the above S2, the suction process determines the position of the sucked foreign matter through the insertion length and deflection angle of the main suction tube 41, and records it in real time, so as to facilitate the subsequent anti-inflammatory treatment of the affected area and accurately correspond to the anti-inflammatory treatment position.

[0055] In summary: on the one hand, the position of the foreign body before suction is guided and positioned with an endoscope, so that the negative pressure suction end corresponds precisely to the position of the foreign body, thereby achieving the purpose of precise control of suction; on the other hand, through a double suction component based on pneumatic suction, combined with an intelligent control system after detecting the position, side suction and top suction or a combination of the two are selected to complete the precise suction of foreign bodies at different positions in the oral cavity, avoiding the frequent extension and retraction of the negative pressure suction end which affects the suction accuracy, resulting in the inability to accurately correspond to the position of the subsequent anti-inflammatory treatment of the affected area.
