Description

Technical Field

[0001] The present invention belongs to the technical field of gastroscope fixation, and specifically relates to a fixation device after gastroscope insertion. Background Art

[0002] In order to prevent the displacement of the endoscope body, stabilize the surgical operation, and reduce the burden on doctors, during gastroscope examination or anal treatment, a fixation device after gastroscope insertion is required, especially for the extracorporeal segment near the proximal end of the patient's oral cavity. During fixation, manual or extracorporeal stent lifting and positioning are usually used.

[0003] The prior art document, a gastroscope auxiliary operation device with the application number CN202310995705.0, includes a bed body. The person to be examined lies on the bed body, and the extracorporeal tube of the endoscope is inserted into the oral cavity of the person to be examined; a limiting component is arranged on the upper surface of the bed body, and this limiting component is used to fix the head of the person to be examined. This gastroscope auxiliary operation device adjusts the fixing cover above the head and inflates the airbag inside it to make it expand, so as to reduce the gap between the head of the person to be examined and the fixing cover, which is beneficial to restricting the position of the head of the person to be examined and preventing the head of the person to be examined from moving randomly. And through the reverse rotation of multiple groups of lower moving rollers and upper moving rollers, the extracorporeal tube of the endoscope is pushed backward, which is convenient for adjusting the extracorporeal tube of the endoscope, liberating the hands of medical staff, and reducing the fatigue of the medical staff's arms; the fixation device of this gastroscope mainly assists gastroscope examination by fixing and adjusting the head position of the patient. However, the examined body position and state of the patient are only applicable to the lying position under general anesthesia, and the examination sites are limited, and it has poor applicability to the intestinal organs that require local anesthesia and specific body position examinations, reducing the examination efficiency and accuracy.

[0007] Preferably, a rotating rod is fixedly connected to the side wall of the gear, an arc-shaped plate penetrates through the outer wall of the rotating rod, both sides of the arc-shaped plate are fixedly connected to the right-angle plate, the rotating rod is slidably connected to the arc-shaped plate through an arc groove, and a circular ring sleeve is fixedly connected to the end of the rotating rod away from the gear.

[0008] Preferably, a groove is formed at the bottom of the right-angle plate, and the side wall of the rack is slidably connected in the groove.

[0009] Preferably, the telescopic member includes a hypotenuse arc plate fixedly connected to the outer walls of the arc-shaped plate and the right-angle plate at the same time, an inclined groove is formed on the side of the hypotenuse arc plate, a round-headed hook rod is movably connected in the inclined groove of the hypotenuse arc plate, a moving rod is fixedly connected to the side of the round-headed hook rod away from the hypotenuse arc plate, and the moving rod is slidably sleeved in the inner cavity of the circular ring sleeve.

[0010] Preferably, a threaded sleeve is fixedly connected to the side of the moving rod away from the hypotenuse arc plate, a limiting ring is rotatably connected to the side of the threaded sleeve away from the moving rod, a U-shaped plate is fixedly connected to the threaded sleeve through the limiting ring, and the inner cavity of the U-shaped plate is clamped on the gastroscope body through an insertion plate.

[0011] Preferably, a threaded locking rod rotatably penetrates through the middle of the U-shaped plate and the insertion plate, and the outer wall of the threaded locking rod is threadedly connected to the inner cavity of the threaded sleeve.

[0012] Preferably, a push-pull plate is fixedly connected to the side of the right-angle plate away from the electric push rod, the outer wall of the push-pull plate is slidably abutted against the top of the mounting plate, and two pairs of fixing columns are fixedly connected to the side of the push-pull plate away from the right-angle plate.

[0013] Preferably, a pair of first push rods are rotatably connected to the bottom of a pair of the fixing columns, the outer wall of the lower end of the first push rod abuts against the arc edge of the mounting plate, and a pair of second push rods are rotatably connected to the bottom of the other pair of the fixing columns.

[0014] Preferably, a bottom plate is rotatably connected to the upper ends of a pair of the first push rods and the second push rods together, and a placement table is fixedly connected to the top of the bottom plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: Through the cooperation of structures such as a right-angle plate and a threaded locking rod, the present invention facilitates the accuracy of device positioning. The threaded locking rod penetrates through the U-shaped plate and the insertion plate of the gastroscope body, and the two are threadedly fixed on the threaded sleeve together. So that during the axial movement of the right-angle plate, the lateral offset and the longitudinal vertical height of the gastroscope body can be dynamically adjusted in real time, ensuring that the operating end of the gastroscope body is spatially corresponding to the patient's oral cavity or anus position regardless of whether the patient is in any of the examination postures such as lateral lying, prone lying, supine lying, or knee-chest position, adapting to different patient postures. Thus, while reducing the arm fatigue of medical staff caused by holding the operation part, the accuracy and efficiency of the examination are improved.

[0016] Through the cooperation of structures such as a bevel arc plate, a round-head hook rod, and a moving rod, the present invention is used to change the distance between the gastroscope body and the patient. When the right-angle plate moves axially, it then drives the moving rod to rotate and displace while making the moving rod perform a telescopic movement along the bevel arc of the bevel arc plate, thereby changing the distance between the gastroscope body and the patient, further enhancing the adaptability of the fixing device after the gastroscope is inserted. And the setting of the round-head hook rod on the side away from the arc plate on the bevel arc plate enables the inner cavity of the bevel arc plate to always squeeze the round-head hook rod to keep it in a relatively horizontal state during the movement of the moving rod along the bevel arc plate. Thus, it drives the moving rod and the gastroscope body to avoid angular deflection during the movement, reducing the number of times the staff repeats fixing the gastroscope body and lowering the operation difficulty.

[0017] Through the cooperation of structures such as a first push rod and a second push rod, the present invention facilitates the parallel movement of the storage table. When the right-angle plate drives the push-pull plate to move axially, the first push rod is continuously squeezed to rotate by the arc edge of the mounting plate. The second push rod is not only parallel to the first push rod but also has the same rotation radius. Therefore, the bottom of the bottom plate is stably supported and moves obliquely upward, making the relative distance between the storage table and the gastroscope body basically unchanged, so that the medical staff can place and retrieve medical supplies on the storage table at the same rate, improving the examination efficiency.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] As Figures 1 to 11 shown, the present invention provides a fixing device for a gastroscope after insertion, including a mounting plate 1, an electric push rod 2 is fixedly connected to one side of the top of the mounting plate 1, an adjusting and positioning mechanism 3 is arranged on the other side of the top of the mounting plate 1, and a gastroscope body 4 and a follow-up moving mechanism 5 are respectively arranged on the adjusting and positioning mechanism 3; The adjusting and positioning mechanism 3 includes a rotating member 31 and a telescopic member 32; The follow-up moving mechanism 5 includes a first push rod 53, and the rotation angle range of the first push rod 53 is from zero to ninety degrees; Among them, the rotating member 31 includes a right-angle plate 311, and the right-angle plate 311 is fixedly connected to the output end of the electric push rod 2.

[0022] Adopting the above solution: In the prior art, the initial posture for common gastroscopy and colonoscopy examinations is the left lateral position, with the knees flexed towards the chest. During the examination, it may be adjusted to: the prone position for facilitating the examination of the rectum, the supine position for facilitating the observation of the ascending colon, and the knee-chest position, usually entering from the anus and assisting in advancing the endoscope if necessary. Therefore, the position of the device that fixedly follows the moving mechanism 5 may need to be changed at any time. After installing the mounting plate 1 to the head of the examination bed, as Figure 1 shown is the position where the patient maintains the initial left lateral position. During the examination, the device can be adjusted along the Figure 1 direction indicated by the arrow to Figure 4 a state to adapt to the patient's prone position, then adjusted to Figure 5 a state to adapt to the examination when the patient is in the supine position, and finally adjusted to Figure 6 a state to adapt to the examination when the patient is in the knee-chest position.

[0023] As Figure 1 and Figure 8 shown, a straight groove is opened at the top of the mounting plate 1. The bottom of the right-angle plate 311 is slidably connected to the straight groove. At the bottom corner of the right-angle plate 311, a gear 314 is rotatably connected through a support plate. The outer wall of the gear 314 penetrates through the bottom of the right-angle plate 311 and abuts against a rack 315. The bottom of the rack 315 is fixedly connected to the straight groove.

[0024] As Figures 4 to 8 shown, a rotating rod 313 is fixedly connected to the side wall of the gear 314. An arc-shaped plate 312 penetrates through the outer wall of the rotating rod 313. Both sides of the arc-shaped plate 312 are fixedly connected to the right-angle plate 311. The rotating rod 313 is slidably connected to the arc-shaped plate 312 through an arc groove. A circular ring sleeve 316 is fixedly connected to the end of the rotating rod 313 away from the gear 314. A groove is opened at the bottom of the right-angle plate 311. The side wall of the rack 315 is slidably connected to the groove.

[0025] Adopting the above solution: The height and width of the right-angle plate 311 are adjusted and designed according to the actual needs of the patient. A plurality of clamping teeth are fixedly connected to the side of the rack 315 close to the electric push rod 2. The side away from the electric push rod 2 is a smooth plate surface, and the plate surface slidably abuts against the teeth of the gear 314 to ensure that the gear 314 can not only slide axially on the rack 315 but also meshingly rotate on the rack 315, facilitating the multi-position adjustment of the auxiliary gastroscope body 4.

[0026] As Figures 2 to 4As shown in the figure, the telescopic member 32 includes a hypotenuse arc plate 325 fixedly connected to the outer walls of the arc plate 312 and the right-angle plate 311 at the same time. An inclined groove is formed on the side of the hypotenuse arc plate 325. A round-head hook rod 326 is movably connected in the inclined groove of the hypotenuse arc plate 325. A moving rod 321 is fixedly connected to the side of the round-head hook rod 326 away from the hypotenuse arc plate 325. The moving rod 321 is slidably sleeved in the inner cavity of the ring sleeve 316; a threaded sleeve 322 is fixedly connected to the side of the moving rod 321 away from the hypotenuse arc plate 325. A limiting ring is rotatably connected to the side of the threaded sleeve 322 away from the moving rod 321. The threaded sleeve 322 is fixedly connected to a U-shaped plate 323 through the limiting ring. The inner cavity of the U-shaped plate 323 is clamped on the gastroscope body 4 through an insertion plate; a threaded locking rod 324 is rotatably penetrated through the middle of the U-shaped plate 323 and the insertion plate. The outer wall of the threaded locking rod 324 is threadedly connected to the inner cavity of the threaded sleeve 322.

[0027] Adopting the above scheme: The gastroscope body 4 is mainly composed of a light guide plug head, an operation part, an insertion part, a distal end part and an objective lens connected. The light guide plug head is used to connect the power supply and observe the objective lens picture. The operation part is used to control the rotation and bending of the distal end part. The top of the insertion plate clamped in the U-shaped plate 323 is fixedly connected to the operation part of the gastroscope body 4. So that after the medical staff inserts the insertion part, the distal end part and the objective lens into the patient's body, the operation part can be fixed on the fixing device of the present application, reducing the burden on the medical staff's arm. The limiting ring is used to ensure that the U-shaped plate 323 rotates arbitrarily on the threaded sleeve 322. After the gastroscope body 4 is clamped on the U-shaped plate 323, the gastroscope body 4 and the U-shaped plate 323 are jointly fixed on the threaded sleeve 322 through the threaded locking rod 324 for limiting support. The hook of the round-head hook rod 326 is arranged on the side of the hypotenuse arc plate 325 away from the arc plate 312, which is used to ensure that when the moving rod 321 moves along the outer arc surface of the arc plate 312, under the extrusion of the inner cavity of the hypotenuse arc plate 325, the round-head hook rod 326 is forced to maintain a relatively horizontal state, so as to ensure that the moving rod 321 does not change its angle during the sliding process along with the ring sleeve 316, avoiding the change of the angle of the fixed gastroscope body 4 during adjustment and reducing the number of times of repeated fixation by the staff.

[0028] As Figure 5 and Figure 6 As shown in the figure, a push-pull plate 51 is fixedly connected to the side of the right-angle plate 311 away from the electric push rod 2. The outer wall of the push-pull plate 51 is slidably abutted against the top of the mounting plate 1. Two pairs of fixing columns 55 are fixedly connected to the side of the push-pull plate 51 away from the right-angle plate 311.

[0029] As Figures 9 to 11As shown in the figure, a pair of first push rods 53 are rotatably connected to the bottom of a pair of fixed columns 55. The outer wall of the lower end of the first push rod 53 abuts against the arc edge of the mounting plate 1. Another pair of fixed columns 55 are rotatably connected to the bottom of a pair of second push rods 54. The upper ends of a pair of first push rods 53 and the second push rods 54 are rotatably connected to a bottom plate 56 together. A placing table 52 is fixedly connected to the top of the bottom plate 56.

[0030] Adopting the above scheme: The first push rod 53 and the second push rod 54 have the same rotation radius and are arranged parallel to each other. Therefore, when the first push rod 53 is rotated by being squeezed by the mounting plate 1, a pair of first push rods 53 and a pair of second push rods 54 can support the bottom of the bottom plate 56 at four points simultaneously, so as to ensure the stability of the movement of the placing table 52, which is beneficial to the stable movement of the medical supplies on the placing table 52 at the same time.

[0031] The working principle and usage process of the present invention: First, the mounting plate 1 is installed at the head position of the hospital examination bed by bolts in the prior art. After the patient arrives at the examination bed and takes a position, according to the guidance of the medical staff, the left lateral position is used as the initial posture for the examination. The fixing device takes the Figure 1 shown state as the initial state. At this time, the patient's legs are slightly bent, the mouth contains a dental pad, and the head is tilted slightly backward. The medical staff inserts the objective lens, the tip part and the insertion part of the gastrointestinal endoscope body 4 into the specified position in the patient's body from the patient's oral cavity in sequence. According to the examination needs, the specific position of the operating part is determined. The right-angled plate 311 is axially moved by the electric push rod 2 for fine adjustment, so that the U-shaped plate 323 reaches the position of the operating part of the gastrointestinal endoscope body 4. Then the U-shaped plate 323 is rotated to a suitable position so that the insertion plate below the operating part is clamped on the U-shaped plate 323. Then the threaded locking rod 324 penetrates through the U-shaped plate 323 and the insertion plate, and the two are threadedly fixed to the threaded sleeve 322 together, so as to perform gastrointestinal endoscopy; Secondly, during the examination, if the patient needs to be changed to the prone position, the right-angled plate 311 can be pulled by the electric push rod 2 in the direction of the electric push rod 2. At this time, the gear 314 has not reached the engaging tooth position of the rack 315. Therefore, the moving rod 321 is always in the low position close to the mounting plate 1, as Figure 4 shown, so as to adapt to the position of the patient's oral cavity at this time. If the patient needs to be changed to the supine position, the patient turns face up. Therefore, the right-angled plate 311 is continuously axially pulled in the same direction by the electric push rod 2. At this time, the engaging teeth of the gear 314 and the rack 315 are initially engaged, causing the gear 314 to rotate, and then driving the rotating rod 313 to slide on the arc-shaped plate 312. The moving rod 321 is driven in the same direction through the circular ring sleeve 316, and moves along the surface of the arc-shaped plate 312 in an arc trajectory, roughly as Figure 5As shown in the figure, at this time, the gastroscope body 4 located on the U-shaped plate 323 also moves along the track, so that the gastroscope body 4 reaches the position of the patient's oral cavity at this time. If the patient needs to change to the knee-chest position, the patient kneels on the examination bed with both knees, the chest is close to the bed surface, and the arms are stretched forward. The gastroscope body 4 needs to be inserted through the anus. During this period, according to the different postures or insertion positions of the patient, the model of the gastroscope body 4 needs to be changed according to the actual situation. Therefore, the right-angle plate 311 is axially pulled to the maximum range by the electric push rod 2, as Figure 6 shown. The gear 314 continues to rotate in this process, rotates the rotating rod 313 to the vertical state, and rotates the moving rod 321 and the gastroscope body 4 to the upper position of the right-angle plate 311 through the circular ring sleeve 316 to adapt to the patient's posture at this time. Through the axial movement of the right-angle plate 311, the lateral offset and longitudinal vertical height of the gastroscope body 4 can be adjusted in real time and dynamically, so that no matter the patient is in any of the inspection postures of lateral lying, prone lying, supine lying, and knee-chest posture, it can ensure that the operating end of the gastroscope body 4 is spatially corresponding to the patient's oral cavity or anus position, improving the positioning accuracy of the device; Again, when the right-angle plate 311 moves axially, it can also drive the hypotenuse arc plate 325 to move in the same direction. Since the moving rod 321 slides by squeezing in the inclined groove of the hypotenuse arc plate 325, the moving rod 321 not only rotates but also expands and contracts along the hypotenuse arc of the hypotenuse arc plate 325, thereby changing the distance between the gastroscope body 4 and the patient, further enhancing the adaptability of the fixing device after the gastroscope is inserted; Finally, when the right-angle plate 311 moves axially, the fixedly connected push-pull plate 51 can be pulled in the same direction. The first push rod 53 will continuously approach the mounting plate 1. After abutting against the mounting plate 1, the arc edge of the mounting plate 1 continuously squeezes the first push rod 53, causing the first push rod 53 to rotate. This process is as Figure 10 shown by the arrow direction of rotation. The upper end of the first push rod 53 pushes the bottom plate 56. Under the limit of the second push rod 54, and the rotation radii of the first push rod 53 and the second push rod 54 are the same and they are arranged parallel to each other. Therefore, after the bottom plate 56 is pushed, it moves obliquely upward in a parallel state. The placement table 52 fixedly connected to the top of the bottom plate 56 moves in the same direction while maintaining a parallel state, so as to realize that the placement table 52 follows the gastroscope body 4 to synchronously change the displacement and height, so that the relative distance between the two is basically unchanged, so as to facilitate the medical staff to place and take the medical supplies on the placement table 52 at the same rate.
