Description

Technical Field

[0001] The utility model relates to the technical field of oral surgery instruments, in particular to a surgical curved suction tube with a mouth mirror for oral use. Background Art

[0002] During dental outpatient treatment, the surgical curved suction tube can remove water mist, debris, blood and saliva in the oral cavity to keep the operating field clear. It is an auxiliary instrument used in dental treatment. The existing surgical curved straws have the following problems: when the patient's head is tilted back, the lowest point is the posterior area of ​​the mandibular molars, the junction of the palate and the tongue, etc. The existing straws are mostly made of soft tubes when they leave the factory, and need to be bent deliberately when used. There is no standard for the curvature of the bend, and it is generally based on the ability to suck saliva at the lowest position. This requires medical staff to frequently observe whether the saliva is sucked. The second is that the suction holes of most straws are currently located at the end, and the adsorption force of the straws is very large. When adsorbing through the suction holes at the end, it is easy to cause damage to the oral mucosa. The third is that traditional soft straws cannot block the tongue and pull the corners of the mouth. These two processes require separate instruments to complete, which is very inconvenient. Finally, there is the observation problem involved in the saliva suction process. Traditionally, a special mouth mirror is required to be inserted into the mouth for observation, so sometimes an oral surgery requires 2-3 people to complete, which is very inefficient and costly. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a surgical curved suction tube with a mouth mirror for oral use, so as to solve the technical problems mentioned in the background technology.

[0004] In order to solve the technical problem, the utility model adopts the following technical solutions:

[0005] A surgical curved suction tube with a mouth mirror for oral use comprises a suction tube body, wherein the suction tube body comprises a saliva suction area and a control connection area, an air connection portion and a negative pressure control hole are provided on one side of the control connection area, wherein the air connection portion is located at one end of the suction tube body, and the negative pressure control hole is located on the inner side of the air connection portion, a saliva suction plug is provided on one end of the saliva suction area, a saliva suction hole is provided on the inner side of the saliva suction plug, and a mouth mirror assembly is installed on the inner side of the saliva suction hole.

[0006] A further improvement is that the straw body includes a first bend, a second bend and a third bend, wherein the negative pressure control hole is located at the upper end of the first bend, and the second bend is located between the first bend and the third bend, wherein the first bend and the third bend have a downward bend orientation, and the second bend has an upward bend orientation.

[0007] A further improvement is that a valve is provided on the inner side of the negative pressure control hole extending from the inner wall of the upper end of the tube cavity of the straw body to the position of the gas connection portion.

[0008] A further improvement is that the saliva suction plug is a cylindrical plug body having a fitting soft surface.

[0009] A further improvement is that the saliva suction holes are located on both sides of the straw body close to the saliva suction plug.

[0010] A further improvement is that the mouth mirror assembly comprises a mirror body and a buckle, and the buckle has an inner groove that fits the arc surface of the outer diameter of the straw body.

[0011] A further improvement is that both sides of the mirror body are plane mirrors.

[0012] A further improvement is that a damping shaft is provided between the buckle and the mirror body.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The utility model patent presets multiple bends on the straw to fit the lowest position of the human oral cavity and the comfortable angle for the doctor to hold, so that it can be inserted into the lowest position in the oral cavity to suck saliva, thereby eliminating the need for the doctor to bend the straw every time. Secondly, a saliva suction plug is arranged at the end of the bent straw, and the saliva suction hole is arranged at the side position of the inner side of the saliva suction plug. The saliva suction plug with a smooth design directly contacts the oral mucosa to form a support positioning, and there is no need to deliberately grasp the distance between the straw head and the bottom of the oral cavity. The saliva suction holes on both sides will not directly adsorb the oral mucosa to avoid damaging the mucosa. At the same time, the straw with a bend can serve as a pulling tool when there is no need to suck saliva and some pulling actions on the corners of the mouth are performed, so there is no need for additional disinfection and preparation of pulling tools. Finally, regarding the issue of observing the oral field of view, the utility model patent provides a mouth mirror on the straw near the inner side of the saliva suction hole. The mouth mirror has observation surfaces on both sides and can be rotated, which greatly facilitates the doctor's observation problem. The mouth mirror is provided with a convex setting, which can play a certain blocking role on the tongue to prevent the tongue from sinking and affecting the operation.

DETAILED DESCRIPTION

[0020] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0021] refer to Figures 1 to 4 :

[0022] The utility model patent discloses a surgical curved straw with a mouth mirror for oral use, including a straw body 100. The straw body 100 is preferably made of stainless steel, can be sterilized and reused, and has support and is not easy to deform. The straw body 100 includes a saliva suction area 110 and a control connection area 120. One side of the control connection area 120 is provided with a gas connection part 1 and a negative pressure control hole 2, wherein the gas connection part 1 is located at one end of the straw body 100, the gas connection part 1 is connected to the gas source pipe to provide negative pressure suction, and the negative pressure control hole 2 is located on the inner side of the gas connection part 1. When in use, the hand presses the negative pressure control hole 2 to perform a full-load saliva suction operation. When the negative pressure control hole 2 is released, the negative pressure control hole 2 is connected to the air connection part 1, and most of the gas is sucked in by the negative pressure control hole 2. At this time, a small-load saliva suction work is performed. A saliva suction plug 3 is provided at one end of the saliva suction area 110. The saliva suction plug 3 is preferably made of soft rubber material, and the thickness is determined according to different age groups. The mucous membrane of young people is more fragile, and a thicker and softer material can be selected to mainly protect the mucous membrane while taking into account saliva suction. A saliva suction hole 4 is provided on the inner side of the saliva suction hole 4, and a mouth mirror assembly 5 is installed on the inner side of the saliva suction hole 4. The mouth mirror assembly 5 has an upwardly protruding component that can support the tongue and prevent the tongue from sagging and affecting the operation.

[0023] Specifically, compared to most traditional soft plastic straws, which need to be bent manually, there is no standard for bending. Usually, when the straw is bent and it is found that the saliva is not sucked cleanly, it is taken out for cleaning and disinfection and trimmed again, which increases the workload and is very inconvenient. Here, the straw body 100 includes a first bend 101, a second bend 102 and a third bend 103, wherein the negative pressure control hole 2 is located at the upper end of the first bend 101, and the second bend 102 is located between the first bend 101 and the third bend 103, wherein the first bend 101 The third bend 103 has a downward bend direction, and the second bend 102 has an upward bend direction. With this arrangement, the third bend 103 fits an angle from the lower teeth of the human oral cavity to the lowest point of the oral cavity. At the same time, the doctor grasps the first bend 101 and can have a more comfortable angle for saliva suction. The saliva is sucked away through the first bend, the second bend and the third bend. There is an arc between two adjacent bends. The gas and saliva will change their flow direction when passing through, and a certain buffer zone will be formed. The saliva will not be sucked in a straight suction form, which is not easy to cause discomfort to the patient.

[0024] Continuing with the above description, the gas and saliva will change their flow direction at each bend. When reaching the first bend, because it is exactly the position of the negative pressure control hole 2, it is the position where the human hand presses. If this place is left empty, some blood and saliva will enter the negative pressure control hole 2, and the finger will contact some saliva. In order to prevent this problem from occurring, here, the inner side of the negative pressure control hole 2 is provided with a valve 6 extending from the inner wall of the upper end of the tube cavity of the straw body 100 to the position of the gas connection part 1. The setting of the valve 6 also has another purpose, that is, when the human finger releases the pressure on the negative pressure control hole 2, most of the gas originally The saliva is sucked from the negative pressure control hole 2 and flows toward the air connection part 1. However, the saliva flowing from the other side of the straw body 100 will also be slowly sucked in due to the negative pressure, causing part of the saliva to be sprayed toward the negative pressure control hole 2, resulting in partial contamination of the table surface. Here, after the valve 6 is added, even if the saliva is also sucked in due to the negative pressure, it will not be sprayed out of the negative pressure control hole 2. On the contrary, for operations that produce some clear saliva, the patient can be directly placed in a suitable position and let it rely on the negative pressure to autonomously suck the saliva at a low flow rate, thus freeing both hands for other operations.

[0025] Specifically, the saliva suction plug 3 is a cylindrical plug body, which has a fitting soft surface 31, and the fitting soft surface 31 is located at the bottom.

[0026] Specifically, compared with the traditional method in which most of the saliva suction holes 4 are located at the end of the straw, which may easily damage the oral mucosa if operated improperly, here, the saliva suction holes 4 are located on both sides of the straw body 100 close to the saliva suction plug 3, and the saliva suction plug 3 is in direct contact with the mucosa. The saliva suction plug 3 has a soft contact surface and is not easy to damage the mucosa, while the saliva suction holes 4 located on both sides of the straw body 100 will not directly suck towards the mucosa.

[0027] Specifically, as one of the installation embodiments of the mouth mirror, here, the mouth mirror assembly 5 includes a mirror body 51 and a buckle 52, and the buckle 52 has an inner groove 521 that fits the arc surface of the outer diameter of the straw body 100. During installation, the buckle 52 can be inserted from the end of one side of the straw body 100 close to the saliva suction plug 3, and then the saliva suction plug 3 is plugged into the tube cavity of the straw body 100. Because the buckle 52 has a thickness, it is not easy to move when it is sleeved on the straw body 100. As other embodiments, an annular groove is provided at the outer end of the straw body 100, which is just for the inner groove 521 of the buckle 52 to fit. Preferably, both sides of the mirror body 51 are plane mirrors. Considering that the traditional mirror surface may be broken when colliding with other metal appliances or the action of ultrasonic dental appliances, causing fragments to fall into the oral cavity, here, preferably, the mirror body 51 is made of polished metal, or a metal mirror surface is used as the main body and sprayed with a bright mirror material coating.

[0028] As another optional embodiment, in order to enable the straw to observe multiple angles during oral surgery, in this embodiment, a damping shaft 53 is further provided between the buckle 52 and the mirror body 51. The damping shaft 53 can be a structure such as a soft damping foot pad plus a screw locking structure, serving as a rotating shaft for the rotational cooperation between the mirror body 51 and the buckle 52 of the mouth mirror (refer to Figure 4 ).

[0029] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
