As shown in fig. 8 and 9, when the rectangular plate 7 is driven to move toward or away from the clamp 3, the pull knob 9 is manually pulled to further drive the first pulling rope 8 to move synchronously, when the pull knob 9 is in contact with the end of the adjusting cylinder 2, the clamp 3 is in a closed state, the first spring 10 gradually stretches out when the pull knob 9 is pulled, and the clamp 3 gradually becomes an open state, so that when a foreign matter is clamped, the pull knob 9 is pulled to enable the foreign matter to be located between the two clamps 3, and then the foreign matter is sent to the pull knob 9, and at the moment, the first spring 10 is restored to elastic deformation, and then the clamp 3 is gradually closed, so that the foreign matter is stably clamped by utilizing the elastic deformation of the first spring 10.
On the basis of the reset assembly embodiment, the annular seat 11 further comprises an integrally formed outer annular portion 112, the clamping assembly comprises an arc-shaped plate 14 arranged on the outer annular portion 112, the arc-shaped plate 14 is rotationally connected to the outer annular portion 112 through a rotating shaft, the outer annular portion 112 is fixedly connected with an extension plate 13, one end of a second spring 15 is fixedly connected to the extension plate 13, the other end of the second spring 15 is fixedly connected to one end of the arc-shaped plate 14, the arc-shaped plate 14 is obliquely arranged, the other end of the arc-shaped plate 14 is fixedly connected with a clamping block, and a plurality of groups of clamping grooves 16 which are distributed at equal intervals are formed in positions corresponding to the clamping blocks of the adjusting cylinder 2.
As shown in fig. 6 and 8, when the longitudinal position of the annular seat 11 relative to the adjusting cylinder 2 is adjusted, the first ends of two sets of oppositely arranged arc plates 14 are synchronously pressed, at this time, the second springs 15 are compressed, so that the arc plates 14 deflect, further, the clamping blocks arranged at the tail ends of the arc plates 14 are separated from the clamping grooves 16, at this time, the outer ring 112 is manually pushed, after the position of the annular seat 11 is determined, the arc plates 14 are loosened, the second springs 15 recover deformation, and drive the arc plates 14 to deflect to the initial positions, so that the clamping blocks enter the corresponding clamping grooves 16.
In order to ensure that the annular seat 11 cannot move arbitrarily, when the second spring 15 is in a natural extension state, the clamping block on the arc plate 14 is positioned in the clamping groove 16, the second spring 15 is used for enabling the clamping block to be positioned in the clamping groove 16 in an initial state, and the clamping groove 16 is used for limiting the position of the clamping block, so that the position of the annular seat 11 is limited.
Further, the inner wall of the adjusting cylinder 2 is fixedly connected with a limiting ring 12, and the limiting ring 12 is positioned at one side of the inner ring part 111, which is close to the pull knob 9.
As shown in fig. 8, in the initial state, when the inner ring portion 111 in the annular seat 11 is in contact with the stop collar 12, the pull button 9 is in contact with the end portion of the adjusting cylinder 2 at this time, and the first spring 10 is in a micro-extension deformation state, so that when the pull button 9 is pulled, only the extension deformation amount of the first spring 10 is further increased, when the foreign matter is clamped, the pull button 9 is gradually separated from the end portion of the adjusting cylinder 2, at this time, the first spring 10 is still in extension deformation, and further the elastic potential energy is further increased, and the spacing length between the pull button 9 and the inner ring portion 111 is limited by the stop collar 12, so that the first spring 10 arranged between the pull button 9 is always in an extension state, and further the clamp 3 is ensured to always have clamping force on the foreign matter.
Based on the clamping assembly embodiment, the flaring assembly comprises a retracting rod 20, one end of the retracting rod 20 is rotatably connected with an outer cover plate 18 through a rotating shaft, the other end of the retracting rod 20 is rotatably connected to a cross rod 21 through the rotating shaft, the cross rod 21 is slidably connected with the side wall of the ingress pipe 1 through a ring seat cavity 25 formed in the side wall of the ingress pipe 1, the cross rod 21 is fixedly connected with a pulling ring seat 22, the pulling ring seat 22 is located in the ring seat cavity 25, a second pull rope 23 is fixedly connected to the pulling ring seat 22, and the second pull rope 23 penetrates through the ingress pipe 1 through a channel and is fixedly connected to the inner ring portion 111.
As shown in fig. 3, 4 and 7, when the ring seat 11 drives the pull ring seat 22 to move in the direction approaching to the clamp 3, there are the following two cases;
in case one, synchronous motion: when the cross-sectional shape of the foreign matter does not exceed the cross-sectional edge formed by the plurality of groups of outer cover plates 18 in the initial state, the movement of the pulling ring seat 22 drives the cross rod 21 to synchronously move, and as the outer cover plates 18 are not constrained by acting force, the vertical included angle of the retraction rod 20 cannot change, and then the retraction rod 20 and the outer cover plates 18 synchronously follow the cross rod 21 to move until the outer cover plates 18 are positioned at the peripheral positions of the foreign matter, so that the foreign matter is surrounded, and the foreign matter is prevented from scratching the digestive tract tissues.
In case two, the opening movement: when the cross-sectional shape of the foreign matter exceeds the cross-sectional edge formed by the plurality of groups of outer cover plates 18 in the initial state, as the foreign matter is in the clamped state, the outer cover plates 18 cannot move synchronously along the cross rod 21 due to the blocking of the foreign matter, and the retraction rod 20 deflects in the vertical direction in the process that the cross rod 21 continues to move towards the clamp 3, so that the retraction rod 20 is driven to synchronously drive the plurality of groups of outer cover plates 18 to move away from the inlet pipeline 1 in the axial direction, and the cross-sectional size formed by the plurality of groups of outer cover plates 18 is increased until the cross-sectional size formed by the plurality of groups of outer cover plates 18 is larger than the cross-sectional shape size of the foreign matter, therefore, when the cross rod 21 continues to move, the movement state of the outer cover plates 18 is consistent as in the above condition, and the foreign matter is surrounded, so that the aim of protecting the digestive tract tissue is achieved.
On the basis of the embodiment of the flaring assembly, the sealing assembly comprises a cover plate chamber 24 which is arranged on the outer cover plate 18 and used for accommodating the connecting cover plate 19, the connecting cover plate 19 is connected on the inner wall of the outer cover plate 18 in a sliding way, and the connecting cover plate 19 is positioned at the joint position of two adjacent groups of outer cover plates 18.
As shown in fig. 3 and 4, when the plurality of outer cover plates 18 exhibit the opening movement described in the second case, in order to avoid the gap between the adjacent two sets of outer cover plates 18, the engagement cover plates 19 are disposed between the adjacent two sets of outer cover plates 18, and the engagement cover plates 19 follow the opening degree of the outer cover plates 18 to compensate the gap between the two, thereby further avoiding the damage of the sharp part of the foreign matter to the digestive tract tissues of the patient.
Based on the embodiment of the sealing assembly, the air bag 26 is of an annular structure, the air bag 26 is fixedly connected with a middle supporting plate 30, a through groove for the inlet pipe 1 to penetrate is formed in the middle supporting plate 30, one side of the air bag 26 is connected with a hollow balloon 28 in a penetrating mode through an air inlet pipe 27, the other end of the air bag 26 is fixedly connected with an air outlet pipe 29 in a penetrating mode, and a sealing plug 31 is connected to the air outlet pipe 29 in a screwed mode.
As shown in fig. 1 and 2, when foreign substances in the digestive tract are extracted, the introduction duct 1 needs to be introduced into the digestive tract from the oral cavity of the patient, and thus, in order to avoid the patient from closing the mouth due to uncomfortable feeling generated when the foreign substances are extracted, it is necessary to support the inside of the oral cavity of the patient.
Before the foreign matters in the alimentary canal of the patient are extracted, the air bag 26 is placed in the oral cavity of the patient, and the hollow air bag 28 is pinched by the hand, so that natural air is gradually flushed into the air bag 26, and the air bag 26 is further used for gradually supporting the oral cavity of the patient.
Because the air inlet end and the air outlet end of the hollow balloon 28 are both provided with the one-way valves, when the air balloon 28 is repeatedly pinched, the outside natural air can gradually enter the air bag 26 and cannot escape, after the foreign matter extraction is finished, the air bag 26 can be taken out of the oral cavity of a patient by unscrewing the sealing plug 31 to deflate the air bag 26, the center of the middle supporting plate 30 is provided with the through groove for the passage of the inlet channel 1, and the diameter size of the through groove is larger than that of the inlet channel 1, so that the air bag 26 and the middle supporting plate 30 cannot cause movement interference to the inlet channel 1 when the inlet channel 1 gradually penetrates into the digestive tract of the patient.
Working principle: when the alimentary canal foreign matter extraction device is used, when foreign matters exist in the alimentary canal of a patient, the air bag 26 in the opening supporting assembly is placed in the oral cavity of the patient, the air bag 26 is inflated to support the oral cavity of the patient, the air bag slowly extends into the alimentary canal of the patient and gradually stretches into the introducing canal 1, the condition inside the alimentary canal of the patient is watched by using the miniature camera head arranged at the tail end of the introducing canal 1 and the display screen electrically connected with the miniature camera head until the clamp 3 at the tail end of the introducing canal 1 reaches the position of the foreign matters, the clamp 3 is controlled to stably clamp the foreign matters by manually opening and closing the clamp 3, and then the foreign matters are surrounded by the outer cover plates 18 through the plurality of groups of outer cover plates 18 in the protective cylinder assembly, and then the foreign matters are slowly extracted, so that the foreign matters are taken out from the alimentary canal.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
