Description

Technical Field

[0001] The invention relates to the technical field of gastroscope auxiliary frames, in particular to a neck posture auxiliary fixing frame for painless gastroscope with an integrated mask. Background Art

[0002] Gastroenteroscopy is an endoscopic device used to examine and treat diseases of the digestive tract (including the esophagus, stomach and intestines). It inserts a slender tubular instrument equipped with a camera and light source to observe the conditions inside the digestive tract in real time, thereby helping doctors diagnose various diseases such as gastritis, gastric ulcers, intestinal tumors, etc. In addition, gastroenteroscopy can also perform some therapeutic operations such as biopsy, hemostasis, polypectomy, etc.

[0003] During gastroenteroscopy, the patient's position adjustment is crucial, especially the angle between the head and the torso. The smooth insertion of the gastroscope requires a specific position. The appropriate head and torso angle can reduce the resistance of the airway and digestive tract, allowing the gastroscope to pass more smoothly. Adjusting the patient's position can optimize the doctor's field of view and ensure that the endoscope can clearly observe all parts of the digestive tract during the examination. Incorrect body position may cause obstruction of the field of view, thereby affecting the diagnosis results. Maintaining an improper position for a long time may cause discomfort or pain to the patient. By adjusting the body position, the patient's discomfort during the examination can be reduced, and their comfort and tolerance can be improved. In some cases, fixing the patient's head and torso angle can reduce the risk of injury caused by accidental movement. Ensuring the patient's stability throughout the examination helps prevent accidental displacement of the endoscope.

[0004] Traditional methods of posture fixation often rely on manual operation by medical staff, which causes discomfort and anxiety to patients during the examination and increases the workload of medical staff. After installing the fixation frame, equipment such as a trachea or oxygen mask must also be installed, which is a cumbersome process.

[0005] The existing Chinese patent with publication number CN116350460A discloses a gastroscopy head fixing frame, comprising an examination bed; sliding blocks are slidably connected to the surfaces of the head of the examination bed; the top surfaces of the sliding blocks are fixedly connected to support plates; a sliding rod is fixedly connected between the two support plates; a connecting frame is slidably connected to the surface of the sliding rod; an elastic pad is installed on the top surface of the connecting frame; a tightening module is installed on the surface of one side of the connecting frame; a fixing belt is installed between the other side of the connecting frame and the tightening module, which is fixed by the fixing belt. After the fixing is completed, the patient can still adjust the patient's head position by letting the connecting frame slide on the surface of the sliding rod, so as to facilitate the doctor's subsequent operation and reduce the degree of shaking caused by the patient's discomfort when the doctor inserts the gastroscopy probe into the patient's mouth, so as to make the doctor's operation more convenient and improve the doctor's work efficiency.

[0006] However, in the above technical solution, the fixing frame cannot be automatically adjusted according to the size of the patient's head, and the breathing mask or throat tube still needs to be installed later, there are many processes, low work efficiency, and the angle adjustment of the patient's head and chest posture is not accurate enough, the fixed angle cannot be quantified and thus cannot be recorded and restored, and after the angle adjustment is completed, the angle cannot be self-locked and quickly disassembled, and the steps are still cumbersome and impractical.

DETAILED DESCRIPTION

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0035] Example 1 Reference Figure 1 to Figure 8 , which is the first embodiment of the present invention, provides a neck posture auxiliary fixation frame for painless gastroscopy with an integrated mask, including a support, a fixing mechanism and an angle adjustment mechanism. The patient's lower jaw is fixed by a mandibular support 100 and a chest support 101, so that the angle of the head and torso is adjusted to a suitable entry angle for the gastroscope, and at the same time, one-way rotation and quick disassembly are achieved by the claw 1004.

[0036] Specifically, it includes: a mandibular support member 100 and a chest support member 101 rotatably connected thereto; The fixing mechanism comprises a mounting belt 200 detachably arranged on the outside of the mandibular support 100, a tightening belt 201 is arranged above the mounting belt 200, and a laryngeal mask 202 is arranged on the end surface of the tightening belt 201; The angle adjustment mechanism includes a knob 300 disposed between the chin support 100 and the chest support 101 . The knob 300 is used to control the rotation angle and rotation direction between the chin support 100 and the chest support 101 .

[0037] The mandibular support 100 and the chest support 101 are made of medical plastic materials. The mandibular support 100 is in a semicircular shape to fit the mandibular area, and the chest support 101 is in a semi-elliptical shape to fit the chest area.

[0038] Among them, when performing painless gastroenteroscopy, the patient needs to lie flat, so that as the angle between the mandibular support 100 and the chest support 101 changes, the patient's lower jaw and head are pushed by the mandibular support 100, thereby forming a corresponding angle with the angle of the torso, thereby adjusting the pitch angle of the patient's oropharyngeal tube, facilitating the entry and positioning of the laryngeal tube and the entry of the gastroenteroscopy probe, and preventing the tongue from being dislocated and blocked during the detection process.

[0039] Preferably, a mounting plate 1001 is provided at the end of the mandibular support 100 , a ratchet 1002 is provided on the inner wall of the mounting plate 1001 , a limit plate 1003 is rotatably provided inside the mounting plate 1001 , and a claw 1004 is symmetrically provided on the lower end surface of the limit plate 1003 , and the claw 1004 is meshed with the ratchet 1002 .

[0040] More preferably, the end face of the chest support 101 is fixedly engaged with the limit plate 1003 and rotates with the limit plate 1003, the ratchet 1002 is a one-way ratchet, the claw 1004 is an arc-shaped plastic part and one arc-shaped end of the claw 1004 is fixed on the limit plate 1003, and the other end of the claw 1004 is elastically deformed and separated from the ratchet 1002 when pushed inward.

[0041] Among them, a sliding groove 1005 and an unlocking groove 1006 are opened on the limit plate 1003, and a pressure cover 1007 is provided at the end of the limit plate 1003 away from the ratchet 1002. The inner wall of the pressure cover 1007 is respectively provided with a sliding block 1008 and an unlocking mother block 1009, and the inner wall of the claw 1004 is provided with an unlocking sub-block 1011. The unlocking sub-block 1011 and the unlocking mother block 1009 are also provided with a sliding slope 1012.

[0042] Preferably, when the claw 1004 is engaged with the ratchet 1002, the limit plate 1003 can only rotate unidirectionally with the mounting plate 1001, and the unlocking sub-block 1011 is arranged toward the center of the limit plate 1003, and the sliding slope 1012 thereon is trapezoidal, with the hypotenuse facing the direction of the claw 1004, and the sliding slope 1012 on the unlocking mother block 1009 is in the opposite direction so that the two can fit each other.

[0043] Among them, the sliding block 1008 slides through the sliding groove 1005, so that the sliding block 1008 can slide along the axial direction of the limit plate 1003 without falling off, and the unlocking sub-block 1011 and the unlocking mother block 1009 slide through the unlocking groove 1006 at the same time and the sliding slopes 1012 on the two fit each other. When the unlocking mother block 1009 moves downward, the unlocking sub-block 1011 undergoes elastic deformation toward the center of the circle, so that the claw 1004 disengages from the ratchet 1002 to achieve unlocking.

[0044] Furthermore, a rotating shaft 1013 is slidably provided at the axial position of the limiting plate 1003 , and a first elastic member 1014 is provided between the lower end surface of the rotating shaft 1013 and the mounting plate 1001 . The rotating shaft 1013 is movably fitted with the inner wall of the pressure cover 1007 under the push of the first elastic member 1014 .

[0045] The first elastic member 1014 is a spring and is always in contact with the mounting plate 1001 and the lower end surface of the rotating shaft 1013 , pushing the rotating shaft 1013 upward to be in contact with the pressure cover 1007 .

[0046] More preferably, the outer wall of the mounting plate 1001 is further provided with a mounting buckle 1015 , the mounting belt 200 is movably engaged with the mounting buckle 1015 , a plastic connector is provided between the mounting belt 200 and the tightening belt 201 , and an opening 1016 is provided on the laryngeal mask 202 .

[0047] Among them, reference Figure 1 In other embodiments, the tightening belt 201 is arranged on the outer wall of the mounting belt 200 and can be rotated to the front relative to the mounting belt 200 to connect the laryngeal mask 202. After adjusting the angle between the mandible and the torso, the tightening belt 201 fixes the laryngeal mask 202 to the patient's mouth, and the gastroscope lens enters through the opening 1016.

[0048] In summary, when in use, the chin support 100 and the chest support 101 are first fixed by the mounting belt 200, and then the mounting belt 200 is pressed and fixed while the patient lies flat, and the mounting plate 1001 and the chin support 100 are preliminarily positioned by the mounting buckle 1015, and then the chest support 101 is rotated to fit the patient's chest area, and then the patient's chin and the chin support 100 are continuously lifted so that the angle between the head and the torso is adjusted to a suitable angle for the entry of the gastroscope.

[0049] At the same time, when the mandibular support 100 and the chest support 101 are unfolded, the two rotate relative to each other in one direction, and are locked in one direction by the claw 1004 and the ratchet 1002. After adjusting to a suitable angle, the mandibular support 100 and the chest support 101 are locked and cannot be reset; when the gastroscopy examination is completed, the pressure cover 1007 is pressed to push the rotating shaft 1013 to compress the first elastic member 1014 downward, and at the same time, the unlocking mother block 1009 on the pressure cover 1007 slides downward along the sliding slope 1012, and squeezes and pushes the unlocking sub-block 1011 to swing toward the center of the limit plate 1003 to produce elastic deformation, and the claw 1004 disengages from the ratchet 1002, and the one-way rotation limit of the mandibular support 100 and the chest support 101 is cancelled, and the two can be quickly disassembled after rotation and reset.

[0050] Example 2 Reference Figure 1 to Figure 11 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but differs in that the shaft 1013 extends and passes through the pressure cover 1007 and is connected to the knob 300, so that the rotation angle and rotation direction between the mandibular support 100 and the chest support 101 can be adjusted through the knob 300.

[0051] Specifically, a rotating hole 2001 is provided at the axial center of the pressure cover 1007 , one end of the rotating shaft 1013 passes through the rotating hole 2001 and is connected to the knob 300 , and the mounting plate 1001 also includes a clamping plate 2002 movably engaged therewith, and the other end of the rotating shaft 1013 is connected to the clamping plate 2002 .

[0052] Among them, a slide groove 2003 is opened on the inner wall of the rotating hole 2001, and a rotation groove 2004, a tightening groove 2005 and a disassembly groove 2006 are vertically opened on the inner wall of the slide groove 2003 respectively. The outer wall of one side of the rotating shaft 1013 extending to the inner wall of the rotating hole 2001 is provided with an adjustment block 2007, and the adjustment block 2007 slides along the inner wall of the slide groove 2003.

[0053] Among them, the adjustment block 2007 is a waist-shaped block and its two ends are symmetrically distributed on the outer wall of the rotating shaft 1013. The sliding groove 2003, the rotating groove 2004, the tightening groove 2005 and the disassembly groove 2006 are all symmetrically arranged about the axis of the rotating hole 2001. The sliding groove 2003 is also perpendicular to the rotating groove 2004, the tightening groove 2005 and the disassembly groove 2006.

[0054] Among them, the two ends of the slide groove 2003 are respectively connected to the rotation groove 2004 and the tightening groove 2005, the rotation groove 2004 is a complete circular ring, the tightening groove 2005 is an arc groove in the clockwise direction starting from the slide groove 2003, and the disassembly groove 2006 is an arc groove in the counterclockwise direction starting from the slide groove 2003.

[0055] More preferably, the clamping plate 2002 has a hole 2008 at its axis, and one end of the rotating shaft 1013 close to the first elastic member 1014 slides through the hole 2008 . A spiral groove 2009 is formed on the inner wall of the hole 2008 , and a sliding column 2011 is disposed on the outer wall of the rotating shaft 1013 .

[0056] Furthermore, the slide column 2011 is slidably disposed on the inner wall of the spiral groove 2009 , and both ends of the first elastic member 1014 are respectively connected to the end surface of the rotating shaft 1013 and the clamping disk 2002 , and the outer wall of the clamping disk 2002 is provided with anti-slip grooves 2012 .

[0057] Among them, two clamping plates 2002 are symmetrically provided, and the anti-skid pattern 2012 is a rubber anti-skid layer, which is used to provide buffering and anti-skid when the clamping plate 2002 contacts the human face. When the clamping plate 2002 contacts the human face, it cannot rotate due to friction.

[0058] More preferably, a plurality of linear arrays of tightening grooves 2005 are provided, and the adjustment block 2007 can be engaged in the tightening groove 2005 when the face size is different, the moving distance of the clamping plate 2002 is changed, and the downward moving distance of the rotating shaft 1013 is different.

[0059] In summary, in the initial state, the adjustment block 2007 on the rotating shaft 1013 is located in the slide groove 2003. When the knob 300 is pushed inward during operation, the adjustment block 2007 slides inward along the slide groove 2003. At this time, the pressure cover 1007 and the limit plate 1003 do not move accordingly. The other end of the rotating shaft 1013 pushes the two clamping plates 2002 to move synchronously toward the middle through the first elastic member 1014 and the slide column 2011 until the clamping plates 2002 fit to the patient's face and are fixed. Adaptive clamping and fixation are performed according to the size of each patient's face to improve the application scenario.

[0060] At the same time, the knob 300 is continued to be pushed. At this time, the first elastic member 1014 is compressed, and the slide column 2011 starts to rotate along the spiral groove 2009. The clamping disk 2002 and the rotating shaft 1013 produce relative movement. The clamping disk 2002 is fixed, so that the rotating shaft 1013 and the slide column 2011 rotate. At this time, the adjustment block 2007 moves to the tightening groove 2005 and rotates 90° from the slide groove 2003 to enter the tightening groove 2005. When continuing to rotate, the rotating shaft 1013 and the adjustment block 2007 drive the pressure cover 1007 to rotate together through the tightening groove 2005, and the limit plate 1003 connected to the pressure cover 1007 rotates to realize the angular rotation of the chest support 101, thereby realizing the angle adjustment between the chest support 101 and the mandibular support 100 according to the pressing depth of the knob 300.

[0061] When use is completed and it needs to be released, the knob 300 is rotated in the opposite direction. When the first rotation is 90°, the shaft 1013 and the adjustment block 2007 are screwed out from the tightening groove 2005, and then rebound to the disassembly groove 2006 under the push of the first elastic member 1014. When the second rotation is continued by 90°, the adjustment block 2007 enters the deepest part of the disassembly groove 2006. At this time, the knob 300 is continued to be pressed downward, and the pressure cover 1007 and the limit plate 1003 are driven by the adjustment block 2007 and the disassembly groove 2006 to move downward to release the engagement between the claw 1004 and the ratchet 1002. At the same time, the knob 300 is rotated to rotate the mandibular support 100 and the chest support 101 to reset. The opening degree is controlled by the knob 300 to avoid accidental touch. The number of rotations of the knob 300 is used as a reference standard to quantify the mandibular deflection angle.

[0062] Example 3 Reference Figure 1-Figure 11 , which is the third embodiment of the present invention, is based on the previous embodiment, except that the compression wheel 3003 is driven to rotate by the tightening belt 3001 to adjust the tightness of the laryngeal mask 202, and the laryngeal mask 202 is further fixed and limited, while simplifying the installation steps and lowering the usage threshold.

[0063] Specifically, a tightening band 3001 is provided between the pressure cover 1007 and the inner wall of the installation plate 1001 , one end of the tightening band 3001 is fixed on the pressure cover 1007 , a guide frame 3002 is provided on the outer wall of the installation buckle 1015 , and the other end of the tightening band 3001 penetrates into the inside of the guide frame 3002 .

[0064] One end of the guide frame 3002 is U-shaped, and the tightening belt 201 is fitted on the inner wall of the guide frame 3002 . A clamping wheel 3003 and a steering wheel 3004 are rotatably provided on the inner wall of the guide frame 3002 .

[0065] Furthermore, the axis of the clamping wheel 3003 is parallel to the vertical direction of the guide frame 3002, and the axis of the steering wheel 3004 is perpendicular to the axis of the clamping wheel 3003. The tightening belt 3001 passes through the steering wheel 3004 inside the guide frame 3002 and is wrapped around the lower end surface of the clamping wheel 3003.

[0066] A spring is provided between the clamping wheel 3003 and the guide frame 3002 . The spring drives the clamping wheel 3003 to always have a tendency to return to its original position after rotation. The tightening belt 3001 itself also has a certain elasticity.

[0067] More preferably, the upper end surface of the clamping wheel 3003 fits the tightening belt 3001 against the inner wall of the guide frame 3002 , and a protrusion is provided on the surface of the clamping wheel 3003 and engages with a pit on the tightening belt 3001 .

[0068] More preferably, a positioning hoop is provided outside the tightening band 201, and a clamping wheel 3003 is provided between the positioning hoop and the tightening band 201. The clamping wheel 3003 can be manually adjusted to adjust the tightness of the laryngeal mask 202, thereby facilitating the adjustment of the position of the laryngeal mask 202.

[0069] In summary, when in use, the tightening belt 3001 is rolled up on the surface of the clamping wheel 3003 in the initial state. When the pressure cover 1007 and the lower chest support 101 rotate, the tightening belt 3001 is pulled to be wrapped around the pressure cover 1007, so that the tightening belt 3001 moves outward and leaves the surface of the clamping wheel 3003, and the clamping wheel 3003 is driven to rotate counterclockwise, thereby driving the tightening belt 200 to move backward and be fixed when the clamping wheel 3003 rotates counterclockwise, so that the laryngeal mask 202 is close to the patient's surface, and the laryngeal mask 202 is used to assist in positioning the patient's lower jaw again to prevent dislocation caused by tilted head, thereby further improving the fixation effect, and at the same time, the laryngeal mask 202 is integrated into an integrated design to avoid the tedious steps of wearing equipment separately, thereby improving operating efficiency.

[0070] Importantly, it should be noted that the construction and arrangement of the present application shown in a number of different exemplary embodiments are only exemplary.
