Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and in particular to a pair of foreign body gripping forceps specially used in stomatology. Background Art

[0002] Dentistry is a medical discipline that primarily diagnoses and treats diseases of the maxillofacial structure, including inflammation, tumors, and deformities of the teeth, mucosa, tongue, and jaw. During dental treatment, it is often necessary to remove foreign objects in the patient's mouth. This removal requires the use of a foreign body removal device.

[0003] Scissor-type tools are commonly used oral medical instruments. To address the problem of "existing scissor-type mechanisms opening too wide when placed in the mouth," Chinese Patent Publication No. CN217430106U discloses a foreign body gripping device specifically for oral care, comprising a connecting structure; the connecting structure is a rectangular strip; the first connecting buckle is mounted on the outside of the connecting structure; the baffle is clamped to the bottom of the connecting structure; the pushing mechanism is located on the inside of the connecting structure; and there are two second connecting buckles, which are clamped to the top of the connecting structure. Although some technical problems have been solved, the following problems still exist:

[0004] In this technical solution, the foreign body gripping device still only has a gripping function, and can only grip foreign bodies with regular shapes and located in superficial positions. However, some foreign bodies that are soft and fragile, irregular in shape, or located deep in the mouth and difficult to grip (such as oral calculus in the throat, tooth tissue separated during impacted tooth extraction, etc.) cannot be removed. In addition, during the gripping process, the foreign body is prone to breakage, making it impossible to complete subsequent diagnosis and treatment, or falling into the patient's digestive tract or respiratory tract. Therefore, corresponding improvements are made to address this problem in order to make it safer and easier to use. Summary of the Invention

[0011] Further, in the present invention, the airbag is provided with a straw connected to the suction nozzle, and the suction nozzle is provided with a mesh plate for blocking foreign objects.

[0012] Further, in the present invention, a ring is sleeved outside the sleeve, the ring is provided with an annular chute, a slider is arranged in the annular chute, the slider is rotatably connected to a shaft column, and the shaft column is provided with a support plate for support.

[0013] Further, in the present invention, the sleeve is provided with a long chute, and the ring is provided with a T-shaped sliding strip inserted into the long chute.

[0014] Further, in the present invention, the sleeve is provided with an elastic member for driving the main rod to reset.

[0015] Furthermore, in the present invention, the above-mentioned main rod is provided with a first boss, the first boss is provided with a slot for clamping the elastic member, the sleeve is provided with a second boss, the first boss is provided with a positioning column, the elastic member is provided with a long hole for the positioning column to pass through, and a circular hole is provided at the end of the long hole, and the diameter of the circular hole is greater than the width of the long hole.

[0016] Furthermore, in the present invention, the first clamping portion and the second clamping portion are provided with aligned cutting edges.

[0017] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0018] 1. After disassembling the suction assembly, hold the first handle and the second handle with your hands. Apply force to move the first clamping part and the second clamping part closer to each other, which can clamp foreign objects. After releasing, the first clamping part and the second clamping part move away from each other, releasing the clamped foreign objects. This is suitable for clamping larger and harder foreign objects. After installing the suction assembly, apply force to move the first clamping part and the second clamping part closer to each other, forcing the airbag to discharge air. After releasing, move the first clamping part and the second clamping part away from each other, and the airbag automatically recovers, sucking air during the recovery process. When releasing, let the suction nozzle close to the foreign object. The negative pressure formed at the suction nozzle can fix the foreign object, and then the foreign object can be taken out. This is suitable for clamping smaller and softer foreign objects. The foreign body gripping forceps specially designed for oral surgery of the present invention have both gripping and suction functions, and can cope with different usage scenarios.

[0019] 2. The sleeve and main rod are connected by an elastic member. When the first and second handles are firmly gripped to allow the dental foreign body grasping forceps to grasp and remove foreign bodies, the elastic member is stretched. When the first and second handles are released, the elastic member automatically returns to its original shape, thereby causing the sleeve and main rod to reset, achieving automatic release and making it more convenient to use.

[0020] 3. The ring can slide on the sleeve, and the frame can be supported on the teeth. With the support, the vibration amplitude during clamping can be smaller and the movement can be more stable, avoiding the risk of foreign objects falling and affecting the patient's digestive tract or respiratory tract.

[0034] Embodiment 1

[0035] Please refer to Figure 1 As shown, a special foreign object clamping forceps for stomatology in Embodiment 1 of the present invention is described in detail as follows.

[0036] Combined with Figure 1 As shown, a special foreign object clamping forceps for stomatology in Embodiment 1 mainly consists of two parts: a sleeve 1 and a main rod 2. The main rod 2 is inserted into the inside of the sleeve 1, and the left and right ends of the main rod 2 extend from the left and right ends of the sleeve 1.

[0037] Furthermore, as Figure 1 shown, a first handle 202 is fixedly installed at the left end of the main rod 2, and the first handle 202 and the main rod 2 are perpendicular to each other. The first handle 202 and a second handle 203 are rotatably connected, and they form a scissor structure. A two-link rod 4 is fixedly connected to the free end of the second handle 203. The two-link rod 4 is composed of two straight rods with their ends rotatably connected. The right end of the two-link rod 4 is rotatably connected to the sleeve 1. Combined with Figure 1 shown, when the first handle 202 and the second handle 203 are firmly held, the main rod 2 moves to the left.

[0038] In some embodiments of this embodiment, combined with Figure 1As shown, a long and vertically downward second clamping part 101 is installed at the right end of the sleeve 1, and a long and vertically downward first clamping part 201 is installed at the right end of the main rod 2. The first clamping part 201 and the second clamping part 101 are parallel to each other. When the first clamping part 201 and the second clamping part 101 approach each other, they play a clamping role, and when they move away from each other, they play a loosening role.

[0039] Furthermore, in combination with Figure 7 and Figure 8 As shown, openings are provided on the left side of the first clamping part 201 and the right side of the second clamping part 101. A first clamping block 2011 and a second clamping block 1011 are respectively inserted into the openings. The cooperation of the first clamping block 2011 and the second clamping block 1011 can be used to pick up foreign objects. Moreover, cutting edges 9 are installed on the tops of both the first clamping block 2011 and the second clamping block 1011. When the first clamping block 2011 and the second clamping block 1011 approach each other, the cutting edges 9 are aligned to play a cutting role for cutting off foreign objects and increasing the usage functions.

[0040] Referring to Figure 7 and Figure 8 As shown, the suction component 3 is mainly composed of an airbag 301, a suction nozzle 302 and a clamping sleeve 303. An upward first mounting strip 2012 is installed on the top of the first clamping block 2011, and a downward second mounting strip 1012 is installed on the bottom of the second clamping block 1011. The clamping sleeve 303 with a "concave" cross-section is installed on the left and right sides of the airbag 301. The left clamping sleeve 303 is stuck on the second mounting strip 1012, and the right clamping sleeve 303 is stuck on the first mounting strip 2012. Through the cooperation of the clamping sleeve 303 with the first mounting strip 2012 and the second mounting strip 1012, detachable connection can be achieved.

[0041] Furthermore, in combination with Figure 8 As shown, a straw 304 is connected to the bottom of the airbag 301, and a suction nozzle 302 is installed at the bottom end of the straw 304. When the first clamping block 2011 and the second clamping block 1011 approach each other, the airbag 301 is compressed, and the gas in the airbag 301 is ejected from the suction nozzle 302. Then, the suction nozzle 302 is aligned with the foreign object, and then the first clamping block 2011 and the second clamping block 1011 are separated from each other, and the airbag 301 will inhale, and the negative pressure formed at the suction nozzle 302 will suck the foreign object into the suction nozzle 302 for fixation.

[0042] It should be noted that a net plate 305 is provided inside the suction nozzle 302, and the net plate 305 plays a blocking role to prevent foreign objects from entering the airbag 301 and ensuring that the suction component 3 has a long service life.

[0043] Embodiment 2

[0044] The special foreign object clamping forceps for stomatology in this embodiment are further optimized on the basis of Embodiment 1, and the specific structure is described as follows.

[0045] Combined with Figure 2 、 Figure 3 and Figure 5 、 Figure 6 As shown in, a mounting opening 102 penetrating the bottom is provided at the top of the sleeve 1. A long strip-shaped limiting rod 5 is inserted into the mounting opening 102. A first rotating shaft 501 is installed at the top of the limiting rod 5, and a second rotating shaft 502 is installed at the bottom of the limiting rod 5. Both the first rotating shaft 501 and the second rotating shaft 502 are horizontal shafts.

[0046] Furthermore, combined with Figure 3 and Figure 6 As shown in, horizontal L-shaped limiting openings 103 are provided on both side walls of the mounting opening 102. The L-shaped limiting openings 103 include a horizontal section, and an inclined section extending upward to the right is connected to the left end of the horizontal section. The horizontal section and the inclined section form an approximately horizontal "L" shape. The two first rotating shafts 501 of the limiting rod 5 are inserted into the L-shaped limiting openings 103 on both sides, and the first rotating shaft 501 can slide along the L-shaped limiting openings 103.

[0047] Even further, combined with Figure 3 and Figure 6 As shown in, a movable opening 204 penetrating to the bottom is provided at the top of the main rod 2. The bottom of the limiting rod 5 is inserted into the movable opening 204, and the second rotating shaft 502 is rotatably connected to the side wall of the movable opening 204.

[0048] Referring to Figure 2 、 Figure 3 and Figure 5 、 Figure 6 As shown in, when the main rod 2 moves along the sleeve 1, the first rotating shaft 501 also slides along the L-shaped limiting opening 103. Relying on the restriction of the L-shaped limiting opening 103 on the first rotating shaft 501, the maximum distances of the main rod 2 moving left and right are restricted, and the use effect is better.

[0049] Embodiment 3

[0050] The special foreign object clamping forceps for stomatology in this embodiment are further optimized on the basis of Embodiment 1, and the specific structure is described as follows.

[0051] In order to make the clamping or sucking process more stable, a ring 6 is installed. Combined with Figure 1 、 Figure 7 and Figure 9As shown in the figure, long strip chutes 104 are provided at both the top and bottom of the sleeve 1. The circular ring 6 is sleeved outside the sleeve 1, and two symmetric T-shaped sliding strips 605 are installed on the inner side of the circular ring 6. The T-shaped sliding strips 605 are inserted into the interior of the long strip chutes 104, and the T-shaped sliding strips 605 can horizontally move left and right along the long strip chutes 104.

[0052] Furthermore, as shown in Figure 9 the figure, an annular chute 601 is provided on the outer side of the circular ring 6, and the cross-section of the annular chute 601 is convex. The slider 602 is installed in the annular chute 601, and the slider 602 can move along the annular chute 601. A shaft column 603 is installed at the bottom end of the slider 602. The shaft column 603 can rotate, and a support plate 604 is installed at the bottom of the shaft column 603. The support plate 604 plays a supporting role.

[0053] As shown in Figure 1 the figure, when in use, the circular ring 6 is slid to a suitable position of the sleeve 1, then the slider 602 is moved to a suitable position, and finally the support plate 604 is placed on the patient's teeth. Thus, while not affecting the flexibility of clamping, the middle part of the sleeve 1 is supported by the support plate 604, so that the shaking amplitude during clamping is smaller, the action is more stable, and the clamping success rate is higher.

[0054] Embodiment 4

[0055] The special foreign object clamping forceps for stomatology in this embodiment are further optimized on the basis of Embodiment 1, and the specific structure is described as follows.

[0056] In order to facilitate the automatic loosening of the special foreign object clamping forceps for stomatology, an elastic member 7 is installed. As shown in Figure 2 and Figure 4 the figure, the elastic member 7 adopts a rectangular rubber sheet. Rubber has good elasticity. The first convex seat 205 and the second convex seat 105 are both triangular protrusions. The first convex seat 205 is fixedly installed on the main rod 2, specifically on the side of the main rod 2 close to the first handle 202; the second convex seat 105 is fixedly installed on the sleeve 1, specifically at the right end of the sleeve 1.

[0057] Furthermore, as shown in Figure 2 and Figure 4 the figure, a card slot is provided on the right side surface of the first convex seat 205. The opening of the elastic member 7 is sleeved down from the top of the first convex seat 205 and is snapped into the card slot. A positioning column 8 is installed on the left side surface of the second convex seat 105. A long strip hole 701 is provided on the elastic member 7. The positioning column 8 is inserted into the long strip hole 701. A round piece is installed at the top of the positioning column 8. The left side of the long strip hole 701 has a round hole 702. The diameter of the round hole 702 is larger than the width of the long strip hole 701, which is convenient for the round piece to be taken out from the round hole 702, and thus it is convenient to remove the elastic member 7.

[0058] When the first handle 202 and the second handle 203 are firmly grasped to make the special oral cavity foreign body clamping forceps play a role in clamping and sucking, the elastic member 7 is stretched at this time. After the first handle 202 and the second handle 203 are released, the elastic member 7 automatically returns to its original state, thereby driving the sleeve 1 and the main rod 2 to reset, achieving automatic release and making it more convenient to use.

[0059] The working principle of the special oral cavity foreign body clamping forceps of the present invention is as follows:

[0060] After the suction component 3 is disassembled, hold the first handle 202 and the second handle 203 by hand. After exerting force, the first clamping portion 201 and the second clamping portion 101 move closer to each other, which can play a role in clamping foreign bodies; after releasing, the first clamping portion 201 and the second clamping portion 101 move away from each other, releasing the clamped foreign body, and it is suitable for clamping larger and harder foreign bodies. After the suction component 3 is installed, force the first clamping portion 201 and the second clamping portion 101 to move closer to each other, forcing the airbag 301 to discharge air; after releasing, let the first clamping portion 201 and the second clamping portion 101 move away from each other, and the airbag 301 automatically recovers. During the recovery process, air is sucked. When released, let the suction nozzle 302 be close to the foreign body, and the negative pressure formed at the suction nozzle 302 can fix the foreign body, and then the foreign body can be taken out, which is suitable for clamping smaller and softer foreign bodies.

[0061] In summary, the present invention provides a special foreign body clamping forceps for stomatology, which includes a sleeve 1 and a main rod 2 inserted into the sleeve 1.
