Description

Technical Field

[0001] The invention relates to the technical field of medical examination, and in particular to a guiding device for a bronchoscope. Background Art

[0002] Bronchoscopy diagnosis and treatment technology is a widely used operation technology in clinical practice, and it has very important clinical significance in the diagnosis and treatment of respiratory diseases.

[0003] The drug guide tube on the clinical bronchoscope structure is fixed to the outside of the wrapping tube by a fixing sleeve. The wrapping tube is a slender structure. During use, especially when the bronchoscope structure is inserted into the patient's mouth, since the bronchoscope structure is directly inserted into the airway from the patient's mouth, the patient will experience severe discomfort during the insertion process. The bronchoscope structure does not have a structure to support the patient's mouth. When the patient is prone to clenching his teeth due to discomfort, it is easy to bite the parts in the bronchoscope structure. Especially for younger patients with poor self-control, the strong discomfort is likely to aggravate the patient's biting sensation, which is not conducive to the further movement of the bronchoscope structure and reduces the inspection efficiency. At the same time, the patient's tongue coating will also interfere with the movement of the bronchoscope structure, thereby causing the bronchoscope structure to deviate from the correct inspection position, thereby further reducing the inspection efficiency.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not 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.

[0029] like Figure 1-5 As shown, a guiding device for a bronchoscope comprises two symmetrically arranged braces 1, and a connecting rod 2 with adjustable length is connected to one side of the two braces 1 close to each other.

[0030] A baffle 3 is rotatably connected to the inner side of the lower brace 1, and a linkage rod 4 is provided between the baffle 3 and the upper brace 1. The angle of the baffle 3 is adjusted in real time through the linkage rod 4 during the adjustment of the distance between the two braces 1;

[0031] Among them, a guide tube 5 for the bronchoscope assembly to pass through is connected to the center of the upper surface of the baffle 3, one end of the guide tube 5 is hinged to the upper surface of the baffle 3, and the other end is slidably connected to the upper surface of the baffle 3 to adapt to the movement of the bronchoscope assembly in the airway;

[0032] A clamping member 6 for clamping the bronchoscope assembly is arranged at the center of the inner cavity of the guide tube 5, and the clamping member 6 can clamp bronchoscope groups of different sizes.

[0033] The device can support the patient's oral cavity through two symmetrically arranged braces, avoiding the biting of the bronchoscope assembly between the patient's upper and lower jaws. At the same time, the baffle can also block the patient's tongue, thereby better exposing the patient's airway at the opening of the guide tube, thereby facilitating the insertion of the entire bronchoscope assembly.

[0034] Specifically, Figure 1-2 As shown, two connecting rods 2 are provided, and the two connecting rods 2 are symmetrically distributed on both sides of the two braces 1. The connecting rod 2 includes a bidirectional threaded sleeve 21 and two threaded rods 22. The bidirectional threaded sleeve 21 is a hollow structure. The two threaded rods 22 are respectively threadedly connected to the two ends of the bidirectional threaded sleeve 21, and the ends of the two threaded rods 22 away from the bidirectional threaded sleeve 21 are respectively connected to the two braces 1 correspondingly.

[0035] Among them, when adjusting, just rotate the bidirectional thread sleeve 21, rotate the two bidirectional thread sleeves 21 synchronously, and the two bidirectional thread sleeves 21 rotate and travel the same distance to ensure the horizontality of the ends of the two braces 1. When the bidirectional thread sleeve 21 rotates in the opposite direction, the spacing between the two braces 1 becomes larger. At this time, the patient's oral cavity is opened more, and the upper brace 1 drives the end of the linkage rod 4 to rise. At this time, the baffle 3 is driven to rise a certain distance under the pull of the linkage rod 4, and the rise of the baffle 3 is also to reduce the excessive squeezing of the patient's tongue coating, because the angle of the patient's oral cavity is large enough to facilitate the exposure of the airway. On the contrary, when the bidirectional thread sleeve 21 rotates forward, the spacing between the two braces 1 becomes smaller. At this time, the patient's oral cavity is opened less, and the upper brace 1 drives the end of the linkage rod 4 to descend. At this time, the baffle 3 is driven to descend a certain distance under the pull of the linkage rod 4, and the descent of the baffle 3 is also to increase the squeezing of the patient's tongue coating, thereby expanding the space inside the patient's oral cavity and facilitating the exposure of the airway.

[0036] Since the braces 1 are mainly designed to match the patient's teeth, and the sizes of the teeth of different patients may vary, the size of the braces 1 also needs to be adaptively adjusted so that the upper and lower braces 1 can be better fixed in the patient's mouth.

[0037] Specifically, Figure 1 and Figure 3 As shown, the surfaces of the ends of the two braces 1 that are away from each other are provided with limiting grooves 7 along their length direction, and both ends of the limiting grooves 7 penetrate the two side walls of the braces 1, and plug posts 8 are slidably inserted between the two opposite side walls of the inner cavity of the limiting grooves 7, and the opposite sides of the two plug posts 8 are connected to extrusion plates 9, and a reset spring 10 mounted on the plug posts 8 is connected between the extrusion plates 9 and the side walls of the limiting grooves 7.

[0038] Further, such as Figure 1 and Figure 3 As shown, the two opposite sides of the two extrusion plates 9 are provided with an inclined surface structure, and a V-shape can be formed between the two inclined surface structures after being extruded and bonded.

[0039] When the patient's upper and lower jaws are in bite, the teeth on the upper and lower jaws will squeeze the squeezing plates 9 on both sides to move. The squeezed squeezing plates 9 drive the plug posts 8 to slide along the side walls of the limiting grooves 7. At this time, the reset spring 10 is squeezed and elastically deformed, pushing the squeezing plates 9 to squeeze on the patient's teeth, thereby fixing the upper and lower braces 1 in the patient's mouth, and the distance between the two squeezing plates 9 is automatically adjusted mainly depending on the size of the patient's teeth.

[0040] Specifically, Figure 1-2As shown, the baffle 3 is configured to be fan-shaped, the longer side of the baffle 3 is rotatably connected to the mouthpiece 1 via a hinge, and the shorter side of the baffle 3 is configured to be an arc shape convex outward.

[0041] Such a configuration facilitates the rotation of the baffle 3 on the one hand, and on the other hand, it also facilitates the baffle 3 to block the patient's tongue coating, thereby avoiding interference of the patient's tongue coating with the insertion of the bronchoscope assembly.

[0042] Since the bronchoscope assembly is mainly inserted above the baffle 3, and the baffle 3 is in a planar structure, in order to prevent the bronchoscope assembly from sliding randomly on the baffle 3, a guide tube 5 is used for guiding and limiting.

[0043] Specifically, Figure 5 As shown, the inner cavity of the guide cylinder 5 is provided with a guide groove 11 along its length direction, and the clamping member 6 is arranged in the inner cavity of the guide groove 11, and the clamping member 6 includes a plurality of sliding posts 61 and a guide seat 62;

[0044] Several sliding columns 61 are slidably inserted on the inner cavity side wall of the guide groove 11, and one end of each sliding column 61 away from the inner cavity side wall of the guide groove 11 is connected to the guide seat 62, and an extrusion spring 63 mounted on the sliding column 61 is connected between the guide seat 62 and the inner cavity side wall of the guide groove 11.

[0045] Further, such as Figure 5 As shown, a guide wheel 64 is provided on one side of each guide seat 62 that is close to the other side.

[0046] When in use, simply insert the inspection end of the bronchoscope assembly into the guide groove 11, and then slowly push the bronchoscope assembly forward. During the pushing process, the bronchoscope assembly gradually squeezes the guide seat 62, and the guide seat 62 is driven to move under the squeezing of the bronchoscope assembly, so that the squeezing spring 63 undergoes elastic deformation. The elastically deformed squeezing spring 63 will also reversely squeeze the guide seat 62, thereby limiting the bronchoscope assembly.

[0047] During use, the bronchoscope assembly may move left and right to match the direction of the airway, and the guide tube 5 is a straight tube structure that is not easy to bend, so the guide tube 5 can be set to a movable style.

[0048] Specifically, Figure 2 and Figure 4 As shown, an arcuate slot 12 is provided on the surface of the baffle 3 at one end away from the hinge point, a slider 13 is slidably connected to the inner cavity of the arcuate slot 12, and the end of the slider 13 away from the arcuate slot 12 is connected to the guide cylinder 5.

[0049] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
