Description

Technical Field

[0001] The present invention relates to the technical field of gastroscope auxiliary frames, and particularly to a neck posture auxiliary fixing frame for painless gastroscopy integrated with a face mask. Background Art

[0002] A gastroscope is an endoscopic device used for examining and treating diseases of the digestive tract (including the esophagus, stomach, and intestines). By inserting a slender tubular instrument equipped with a camera and a light source, it can observe the internal conditions of the digestive tract in real time, thereby helping doctors diagnose various diseases such as gastritis, gastric ulcers, intestinal tumors, etc. In addition, a gastroscope can also perform some treatment operations such as biopsies, hemostasis, polypectomies, etc.

[0003] During a gastroscopy examination, the adjustment of the patient's body position is crucial, especially the angle between the head and the torso. The smooth insertion of the gastroscope requires a specific body position. Appropriate head and torso angles can reduce the resistance of the airway and digestive tract, enabling the gastroscope to pass more smoothly. Adjusting the patient's body 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. An incorrect body position may cause obstruction of the field of view, thus affecting the diagnostic results. Maintaining an improper body position for a long time may cause discomfort or pain to the patient. By adjusting the body position, the discomfort of the patient during the examination can be reduced, improving their comfort and tolerance. In some cases, fixing the head and torso angles of the patient can reduce the risk of injury caused by accidental movement. Ensuring the stability of the patient throughout the examination helps prevent accidental displacement of the endoscope.

[0004] The body posture fixing frames in traditional methods often rely on the manual operation of medical staff, resulting in discomfort and anxiety for patients during the examination. At the same time, it also increases the workload of medical staff. Moreover, after installing the fixing frame, other devices such as laryngeal tubes or oxygen masks need to be installed, and the steps are cumbersome.

[0005] The Chinese patent with the publication number CN116350460A discloses a head fixing frame for a gastroscope, including an examination bed; sliding blocks are slidably connected to both surfaces of the head of the examination bed; support plates are fixedly connected to the top surfaces of the sliding blocks; 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 one side surface of the connecting frame; a fixing belt is installed between the other side of the connecting frame and the tightening module. The patient is fixed by the fixing belt, and after the fixation is completed, the patient can still slide the connecting frame on the surface of the sliding rod to adjust the position of the patient's head to facilitate the doctor's subsequent operations, reduce the degree of shaking of the patient due to discomfort when the doctor inserts the gastroscope probe into the patient's mouth, 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 the laryngeal tube still needs to be installed subsequently. The process is relatively complicated, the work efficiency is low, and the angle and posture adjustment of the patient's head and chest is not precise enough. The fixed angle cannot be quantified, so it cannot be recorded and restored. Moreover, after the angle adjustment is completed, angle self-locking and quick disassembly cannot be achieved, and the steps are still cumbersome and not very practical. Summary of the Invention

[0038] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following detailed description of the specific embodiments of the present invention will be made in conjunction with the accompanying drawings of the specification.

[0039] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may be implemented in other ways different from those described herein. Those skilled in the art may make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0040] Secondly, the so-called "one embodiment" or "embodiment" refers to specific features, structures, or characteristics that may be included in at least one implementation of the present invention. The phrase "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that excludes other embodiments.

[0041] Embodiment 1

[0042] Referring to Figures 1 to 8 , which is the first embodiment of the present invention. This embodiment provides a painless gastroscope neck posture auxiliary fixing device integrated with a mask, including a support member, a fixing mechanism, and an angle adjustment mechanism. The mandibular support 100 and the chest support 101 are used to fix the patient's mandible, so that the angle between the head and the torso is adjusted to a suitable angle for the gastroscope to enter. At the same time, one-way rotation and quick disassembly are achieved through the clamping jaw 1004.

[0043] Specifically, it includes: a mandibular support 100 and a chest support 101 rotatably connected thereto;

[0044] A fixing mechanism, including a mounting strap 200 detachably provided outside the mandibular support 100, a tightening strap 201 is provided above the mounting strap 200, and a laryngeal mask 202 is provided on the end face of the tightening strap 201;

[0045] An angle adjustment mechanism, including a knob 300 provided between the mandibular support 100 and the chest support 101, and the knob 300 is used to control the rotation angle and rotation direction between the mandibular support 100 and the chest support 101.

[0046] Wherein, the mandibular support 100 and the chest support 101 are made of medical plastic. The mandibular support 100 is in the shape of a semi-circular ring to fit the mandibular area, and the chest support 101 is in the shape of a semi-ellipse to fit the chest area.

[0047] Wherein, during painless gastroscopy and colonoscopy examinations, the patient needs to lie flat. Thus, as the angle between the mandibular support 100 and the chest support 101 changes, the patient's mandible and head are pushed by the mandibular support 100, so that the angle formed with the trunk forms a corresponding angle, realizing the adjustment of the pitching angle of the patient's oropharyngeal tube, facilitating the entry and positioning of the laryngeal tube and the entry of the gastroscope probe, and preventing the tongue from being misaligned and blocking during the examination.

[0048] Preferably, an installation disk 1001 is provided at the end of the mandibular support 100, ratchet teeth 1002 are provided on the inner wall of the installation disk 1001, a limit disk 1003 is rotatably provided in the installation disk 1001, clamping claws 1004 are symmetrically provided on the lower end face of the limit disk 1003, and the clamping claws 1004 are meshed with the ratchet teeth 1002.

[0049] More preferably, the end face of the chest support 101 is fixedly and fittingly connected to the limit disk 1003 and rotates with the limit disk 1003. The ratchet teeth 1002 are one-way ratchet teeth, the clamping claws 1004 are arc-shaped plastic parts, and the arc-shaped end of the clamping claws 1004 is fixedly provided on the limit disk 1003. The other end of the clamping claws 1004 undergoes elastic deformation when pushed inward and separates from the ratchet teeth 1002.

[0050] Wherein, a sliding groove 1005 and an unlocking groove 1006 are opened on the limit disk 1003. A gland 1007 is provided at one end of the limit disk 1003 away from the ratchet teeth 1002. A sliding block 1008 and an unlocking female block 1009 are respectively provided on the inner wall of the gland 1007. An unlocking sub-block 1011 is provided on the inner wall of the clamping claw 1004. Sliding slopes 1012 are simultaneously provided on the unlocking sub-block 1011 and the unlocking female block 1009.

[0051] Preferably, when the jaw 1004 meshes with the ratchet 1002, the limiting disc 1003 can only rotate unidirectionally with the mounting disc 1001. The unlocking sub-block 1011 is arranged towards the center of the limiting disc 1003. The sliding slope 1012 thereon is trapezoidal, and the hypotenuse faces the direction of the jaw 1004. The sliding slope 1012 on the unlocking mother block 1009 has the opposite direction so that the two can fit together.

[0052] Among them, the sliding block 1008 slides through the sliding groove 1005, so that the sliding block 1008 can slide along the axis direction of the limiting disc 1003 without falling off. 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 them fit together. When the unlocking mother block 1009 moves downward, the unlocking sub-block 1011 elastically deforms towards the center, so that the jaw 1004 disengages from the ratchet 1002 to achieve unlocking.

[0053] Furthermore, a rotating shaft 1013 is slidably arranged at the axial center position of the limiting disc 1003. A first elastic member 1014 is arranged between the lower end surface of the rotating shaft 1013 and the mounting disc 1001. The rotating shaft 1013 is in movable contact with the inner wall of the gland 1007 under the push of the first elastic member 1014.

[0054] Among them, the first elastic member 1014 is a spring and always fits the mounting disc 1001 and the lower end surface of the rotating shaft 1013, pushing the rotating shaft 1013 upward to fit with the gland 1007.

[0055] More preferably, a mounting buckle 1015 is further arranged on the outer wall of the mounting disc 1001. The mounting belt 200 is movably embedded on the mounting buckle 1015. A plastic connector is arranged between the mounting belt 200 and the tightening belt 201. An opening 1016 is arranged on the laryngeal mask 202.

[0056] Among them, referring to 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 for connecting the laryngeal mask 202. After adjusting the angle between the mandible and the trunk, the tightening belt 201 fixes the laryngeal mask 202 to the patient's mouth, and the gastroscope lens enters through the opening 1016.

[0057] In summary, when in use, first fix the mandible support 100 and the chest support 101 through the mounting belt 200. Then, when the patient lies flat, press and fix the mounting belt 200, and initially position the mounting disc 1001 and the mandible support 100 through the mounting buckle 1015. Then rotate the chest support 101 to fit the patient's chest area. Then continue to lift the patient's mandible and the mandible support 100 so that the angle between the head and the trunk is adjusted to an angle suitable for the gastroscope to enter.

[0058] Meanwhile, when the mandibular support 100 and the chest support 101 are unfolded, they rotate relative to each other in one direction and are locked in one-way rotation by the pawl 1004 and the ratchet 1002. After being adjusted to a suitable angle, the mandibular support 100 and the chest support 101 are locked and cannot be reset. When the gastroscopy is completed, the pressing cover 1007 is pressed, the rotating shaft 1013 is pushed downward to compress the first elastic member 1014. At the same time, the unlocking master block 1009 on the pressing cover 1007 slides downward along the sliding slope 1012 and squeezes and pushes the unlocking sub-block 1011 to swing towards the center of the limiting disk 1003, causing elastic deformation. The pawl 1004 disengages from the ratchet 1002, canceling the one-way rotation limit of the mandibular support 100 and the chest support 101. After they rotate and reset, they can be quickly disassembled.

[0059] Embodiment 2

[0060] Referring to Figures 1 to 11 , this is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The difference is that the rotating shaft 1013 extends and penetrates through the pressing cover 1007 and is connected to the knob 300, so as to realize the adjustment of the rotation angle and rotation direction between the mandibular support 100 and the chest support 101 through the knob 300.

[0061] Specifically, a rotating hole 2001 is provided at the axial center position of the pressing cover 1007. One end of the rotating shaft 1013 penetrates through the rotating hole 2001 and is connected to the knob 300. The mounting disk 1001 further includes a clamping disk 2002 that is movably fitted therewith. The other end of the rotating shaft 1013 is connected to the clamping disk 2002.

[0062] Among them, a sliding groove 2003 is opened on the inner wall of the rotating hole 2001. Rotating grooves 2004, tightening grooves 2005, and disassembly grooves 2006 are respectively vertically opened on the inner wall of the sliding groove 2003. One side outer wall 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 sliding groove 2003.

[0063] Among them, the adjustment block 2007 is a kidney-shaped block and is symmetrically distributed at both ends 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, and the sliding groove 2003 is perpendicular to the rotating groove 2004, the tightening groove 2005, and the disassembly groove 2006 at the same time.

[0064] Among them, both ends of the sliding groove 2003 are respectively communicated with the rotating groove 2004 and the tightening groove 2005. The rotating groove 2004 is a complete ring, the tightening groove 2005 is an arc-shaped groove in the clockwise direction starting from the sliding groove 2003, and the disassembly groove 2006 is an arc-shaped groove in the counterclockwise direction starting from the sliding groove 2003.

[0065] Preferably, a hole 2008 is formed at the axis of the clamping disc 2002. One end of the rotating shaft 1013 close to the first elastic member 1014 slides through the hole 2008, and a spiral groove 2009 is formed on the inner wall of the hole 2008. A sliding column 2011 is arranged on the outer wall of the rotating shaft 1013.

[0066] Furthermore, the sliding column 2011 is slidably arranged on the inner wall of the spiral groove 2009. Two ends of the first elastic member 1014 are respectively connected to the end face of the rotating shaft 1013 and the clamping disc 2002. Anti-slip lines 2012 are arranged on the outer wall of the clamping disc 2002.

[0067] Among them, two clamping discs 2002 are symmetrically arranged. The anti-slip lines 2012 are rubber anti-slip layers, which are used to provide buffering and anti-slip when the clamping disc 2002 contacts the human face. When the clamping disc 2002 contacts the human face, it cannot rotate due to the existence of friction force.

[0068] Preferably, a plurality of tightening grooves 2005 are linearly arrayed. When the face shapes are different, the moving distances of the clamping discs 2002 change, and the downward moving distances of the rotating shaft 1013 are different, the adjusting block 2007 can be engaged with the tightening groove 2005.

[0069] In summary, in the initial state, the adjusting block 2007 on the rotating shaft 1013 is located in the sliding groove 2003. When the knob 300 is pushed inward during work, the adjusting block 2007 slides inward along the sliding groove 2003. At this time, neither the pressing cover 1007 nor the limiting disc 1003 moves along with it. The other end on the rotating shaft 1013 pushes the two clamping discs 2002 to move synchronously toward the middle through the first elastic member 1014 and the sliding column 2011 until the clamping discs 2002 are attached to the patient's face and thus fixed, achieving adaptive clamping and fixation according to the face shapes of each patient and improving the application scenarios.

[0070] Meanwhile, when the knob 300 is continuously pushed, at this time, the first elastic member 1014 is compressed, and the sliding column 2011 starts to rotate along the spiral groove 2009. A relative movement occurs between the clamping disc 2002 and the rotating shaft 1013, and the clamping disc 2002 is fixed. Thus, the rotating shaft 1013 and the sliding column 2011 rotate. At this time, the adjusting block 2007 moves to the position of the tightening groove 2005 and rotates 90° from the sliding groove 2003 into the inside of the tightening groove 2005. When rotating continuously, the rotating shaft 1013 and the adjusting block 2007 drive the pressing cover 1007 to rotate together through the tightening groove 2005, and the limiting disc 1003 connected to the pressing cover 1007 rotates, realizing the angular rotation of the chest support member 101, so as to adjust the angle between the chest support member 101 and the mandibular support member 100 according to the pressing depth of the knob 300.

[0071] When it is necessary to release the device after use, rotate the knob 300 in the reverse direction. When rotating the first 90°, the rotating shaft 1013 and the adjusting 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 continuing to rotate the second 90°, the adjusting block 2007 enters the deepest part of the disassembly groove 2006. At this time, continue to press down the knob 300. The gland 1007 and the limiting disc 1003 are driven by the adjusting 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, rotate the knob 300 to make the mandibular support 100 and the chest support 101 rotate back to their original positions. The opening degree is controlled by the knob 300 to avoid accidental touch. The number of turns of the knob 300 is used as a reference standard to quantify the mandibular deflection angle.

[0072] Embodiment 3

[0073] Referring to Figures 1 - 11 , this is the third embodiment of the present invention. This embodiment is based on the previous embodiment. The difference is that the tightening belt 3001 drives the pressing wheel 3003 to rotate to adjust the tightness of the laryngeal mask 202, and the laryngeal mask 202 is further used for fixing and limiting, while simplifying the installation steps and reducing the use threshold.

[0074] Specifically, a tightening belt 3001 is provided between the gland 1007 and the inner wall of the mounting disc 1001. One end of the tightening belt 3001 is fixed on the gland 1007. A guiding frame 3002 is provided on the outer wall of the mounting buckle 1015, and the other end of the tightening belt 3001 penetrates into the guiding frame 3002.

[0075] Among them, one end of the guiding frame 3002 is U-shaped, and the tightening belt 201 is attached to the inner wall of the guiding frame 3002. A pressing wheel 3003 and a steering wheel 3004 are respectively rotatably provided on the inner wall of the guiding frame 3002.

[0076] Furthermore, the axis of the pressing wheel 3003 is parallel to the vertical direction of the guiding frame 3002, and the axis of the steering wheel 3004 is perpendicular to the axis of the pressing wheel 3003. The tightening belt 3001 is deflected by the steering wheel 3004 inside the guiding frame 3002 and wound around the lower end surface of the pressing wheel 3003.

[0077] Among them, a hairspring is provided between the pressing wheel 3003 and the guiding frame 3002. The hairspring drives the pressing wheel 3003 to always have a tendency to reset after rotation, and the tightening belt 3001 itself also has a certain elasticity.

[0078] Preferably, the upper end surface of the pressing wheel 3003 fits the tightening belt 3001 on the inner wall of the guiding frame 3002, and protrusions are provided on the surface of the pressing wheel 3003 and engaged with the pits on the tightening belt 3001.

[0079] Preferably, a positioning hoop is sleeved outside the tightening belt 201, and a pressing wheel 3003 is also arranged between the positioning hoop and the tightening belt 201. The pressing wheel 3003 can be manually adjusted to adjust the tightness of the laryngeal mask 202, facilitating the adjustment of the position of the laryngeal mask 202.

[0080] In summary, during use, the tightening belt 3001 is wound around the surface of the pressing wheel 3003 in the initial state. When the gland 1007 and the lower chest support 101 rotate, the tightening belt 3001 is pulled to wind around the gland 1007. As a result, the tightening belt 3001 moves outward and leaves the surface of the pressing wheel 3003, driving the pressing wheel 3003 to rotate counterclockwise. When the pressing wheel 3003 rotates counterclockwise, it drives the tightening belt 200 to move backward and be fixed, making the laryngeal mask 202 closely adhere to the patient's surface. The laryngeal mask 202 is used to assist in positioning the patient's mandible again, preventing misalignment caused by tilting the head, further improving the fixation effect. At the same time, the laryngeal mask 202 is integrated into an integrated design, avoiding the cumbersome steps of separately wearing the equipment and improving the operation efficiency.
