Description

Technical Field

[0001] This invention relates to the field of dentistry, and more particularly to a fixed lip clamp for lip biopsy and surgery. Background Technology

[0002] Lip forceps are medical instruments used in dentistry. Their main function is to provide clamping, traction, and auxiliary support for lip examination and surgical procedures. They are commonly used tools in lip diagnosis and treatment, mainly for lip surgery in dentistry, and can also assist in the clinical examination of lip diseases.

[0003] By clamping and everting the lips, the surgical or examination areas, such as the inner side of the lips and labial glands, are fully opened up, giving doctors a clear and wide field of vision and facilitating precise operations.

[0004] When using existing lip clamps to hold a patient's lips, the doctor typically needs to hold the clamps in one hand while using the other to treat the patient's mouth. Because one hand is occupied by the clamps, the doctor can only perform oral procedures with one hand, placing a high demand on their skills. Summary of the Invention

[0005] To address the aforementioned technical problems, the present invention aims to provide a fixed lip clamp for lip biopsy and surgery. The clamping mechanism is adapted to clamp the patient's lips to expose the inner surface of the patient's lips or the inside of the oral cavity. The fixing mechanism can be fixed to the patient's teeth to fix the position of the clamping mechanism relative to the patient's oral cavity and maintain the state of the lips after being clamped by the clamping mechanism, thereby freeing the operator's hands and facilitating the operator to perform subsequent operations.

[0006] To achieve the above objectives, the present invention aims to provide a fixed lip clamp for lip biopsy and surgery, comprising:

[0007] A clamping mechanism, comprising a first clamping arm and a second clamping arm, wherein a first connecting end of the first clamping arm is rotatably connected to a second connecting end of the second clamping arm, and a clamping space is formed between the first clamping end of the first clamping arm and the second clamping end of the second clamping arm, the clamping space being used to accommodate the patient's lips;

[0008] A fixation mechanism includes a connecting arm and a clamping assembly. One end of the connecting arm is connected to the first clamping arm. The clamping assembly includes a first clamping arm and a second clamping arm. A clamping space is formed between the first clamping arm and the second clamping arm. The clamping space is used to accommodate the patient's teeth.

[0009] In some embodiments, the clamping assembly further includes a limiting frame mounted on the end of the connecting arm away from the first clamping arm. The limiting frame forms a limiting opening around the connecting arm. Both the first clamping arm and the second clamping arm are movably mounted on the limiting opening. Controlling the movement of the first clamping arm and the second clamping arm relative to the limiting frame allows adjustment of the distance between the first clamping arm and the second clamping arm.

[0010] In some embodiments, the clamping assembly further includes a sliding rod disposed at the limiting opening, wherein the first clamping arm and the second clamping arm are slidably mounted on the sliding rod;

[0011] The clamping assembly further includes an elastic element, which is sleeved on the sliding rod and located between the first clamping arm and the second clamping arm. One end of the elastic element is connected to the first clamping arm and the other end is connected to the second clamping arm.

[0012] When the patient's teeth are placed between the first clamping arm and the second clamping arm, the distance between the first clamping arm and the second clamping arm increases, the elastic element is stretched, and the elastic element can apply a pulling force to the first clamping arm and the second clamping arm so that the first clamping arm and the second clamping arm clamp the patient's teeth.

[0013] In some embodiments, along the width direction of the limiting frame, the first clamping arm includes a plurality of first clamping blocks and a first elastic rod arranged sequentially. The first clamping arm also has a first through hole penetrating the plurality of first clamping blocks. The first elastic rod passes through the first through hole, and the two ends of the first elastic rod are respectively connected to two side walls corresponding to the limiting opening.

[0014] Along the width direction of the limiting frame, the second clamping arm includes a plurality of second clamping blocks and a second elastic rod arranged sequentially. The second clamping arm also has a second through hole that passes through the plurality of second clamping blocks. The second elastic rod passes through the second through hole, and the two ends of the second elastic rod are respectively connected to two side walls corresponding to the limiting opening.

[0015] When the patient's tooth is placed in the clamping space between the first clamping arm and the second clamping arm, the contours of the first clamping arm and the second clamping arm can deform to follow the contours of the tooth.

[0016] In some embodiments, the end of the connecting arm away from the clamping assembly is rotatably connected to the first clamping arm.

[0017] In some embodiments, the clamping mechanism further includes a clamping rod and an abutment block. One end of the clamping rod is connected to the side of the second clamping arm near the first clamping arm. The first clamping arm has a clearance opening at a preset position. The end of the clamping rod away from the second clamping arm extends through the clearance opening to the side of the first clamping arm away from the second clamping arm. The abutment block is located on the side of the first clamping arm away from the second clamping arm, and the abutment block is slidably mounted on the clamping rod.

[0018] In the initial state, the first clamping end and the second clamping end are far apart. After the distance between the first clamping end and the second clamping end is shortened and the patient's lips are clamped, the abutment block is slid along the clamping rod so that the abutment block abuts against the first clamping arm to maintain the distance between the first clamping end and the second clamping end.

[0019] In some embodiments, the clamping rod is provided with a threaded structure at a preset position away from the second clamping arm, the abutment block has a threaded hole, and one end of the clamping rod away from the second clamping arm passes through the threaded hole. Rotating the abutment block relative to the clamping rod can control the abutment block to slide along the length extension direction of the clamping rod.

[0020] In some embodiments, the first clamping end of the first clamping arm has an operating port;

[0021] The fixed lip clamp for lip biopsy and surgery further includes a drug delivery mechanism, which includes a mounting rod and a drug delivery tube. The mounting rod is mounted on the end of the connecting arm away from the first clamping arm. The top of the drug delivery tube is connected to the mounting rod, and the bottom of the drug delivery tube extends to the operating port. The end of the drug delivery tube near the mounting rod has a first incision, and the end near the operating port has a second incision.

[0022] In some embodiments, the dosing tube has a mounting ring at one end near the mounting rod, the mounting ring being sleeved on the mounting rod, the mounting ring being able to slide along the length extension direction of the mounting rod, and the mounting ring being able to rotate around the mounting rod.

[0023] In some embodiments, the fixing mechanism further includes a tension band with its two ends connected to the two sides of the first clamping end of the first clamping arm, and the portion of the tension band between the two ends located on the side of the second clamping arm away from the first clamping arm. When the patient's lips are clamped between the first clamping end and the second clamping end, the portion of the tension band between the two ends is adapted to be fitted onto the patient's chin.

Obviously, the drawings described below are merely some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0036] To keep the drawings concise, each figure only schematically shows the parts relevant to the invention, and these do not represent the actual structure of the product. Furthermore, to facilitate understanding, in some figures, only one of components with the same structure or function is schematically depicted, or only one is labeled.

[0037] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0038] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0039] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0040] refer to Figures 1 to 8 This application provides a fixed lip clamp 100 for lip biopsy and surgery. The fixed lip clamp 100 for lip biopsy and surgery includes a clamping mechanism 10 and a fixing mechanism 20. The clamping mechanism 10 is connected to the fixing mechanism 20. The clamping mechanism 10 is adapted to clamp the patient's lips to expose the inner surface of the patient's lips or the inside of the oral cavity. The fixing mechanism 20 can be fixed to the patient's teeth to fix the position of the clamping mechanism 10 relative to the patient's oral cavity and maintain the state of the lips after being clamped by the clamping mechanism 10, thereby freeing the operator's hands and facilitating the operator to perform the corresponding operations.

[0041] Specifically, the clamping mechanism 10 includes a first clamping arm 11 and a second clamping arm 12. The first connecting end 111 of the first clamping arm 11 is rotatably connected to the second connecting end 121 of the second clamping arm 12. A clamping space 110 is formed between the first clamping end 112 of the first clamping arm 11 and the second clamping end 122 of the second clamping arm 12. The clamping space 110 is used to accommodate the patient's lips.

[0042] The fixation mechanism 20 includes a connecting arm 21 and a clamping assembly 22. One end of the connecting arm 21 is connected to the first clamping arm 11. The clamping assembly 22 includes a first clamping arm 221 and a second clamping arm 222. A clamping space 220 is formed between the first clamping arm 221 and the second clamping arm 222. The clamping space 220 is used to accommodate the patient's teeth.

[0043] It should be noted that when the first clamping end 112 and the second clamping end 122 clamp the patient's upper lip, the first clamping arm 221 and the second clamping arm 222 clamp the patient's upper teeth; when the first clamping end 112 and the second clamping end 122 clamp the patient's lower lip, the first clamping arm 221 and the second clamping arm 222 clamp the patient's lower teeth.

[0044] In some embodiments, the distance between the first clamping arm 221 and the second clamping arm 222 is slightly less than the thickness of the tooth, and the patient's tooth is fixedly installed in the clamping space by an interference fit. In some embodiments, the first connecting end 111 of the first clamping arm 11 and the second connecting end 121 of the second clamping arm 12 are integrally connected, and in the initial state, the first clamping end 112 and the second clamping end 122 are close to each other. When the distance between the first clamping end 112 and the second clamping end 122 increases, the first clamping arm 11 and the second clamping arm 12 deform, and after the external force acting on the first clamping end 112 and the second clamping end 122 disappears, the first clamping end 112 and the second clamping end 122 move closer to each other under the action of the elastic restoring force of the first clamping arm 11 and the second clamping arm 12. When it is necessary to place the patient's lips within the clamping space 110, first control the first clamping end 112 and the second clamping end 122 to move away from each other, then place the patient's lips between the first clamping end 112 and the second clamping end 122, and then release the first clamping end 112 and the second clamping end 122, and clamp the patient's lips by the elastic restoring force of the first clamping arm 11 and the second clamping arm 12.

[0045] refer to Figure 1 , Figure 4 as well as Figure 6 Furthermore, the clamping assembly 22 also includes a limiting frame 223, which is installed at the end of the connecting arm 21 away from the first clamping arm 11. The limiting frame 223 forms a limiting opening 2230 around the connecting arm 21. The first clamping arm 221 and the second clamping arm 222 are movably installed in the limiting opening 2230. By controlling the movement of the first clamping arm 221 and the second clamping arm 222 relative to the limiting frame 223, the distance between the first clamping arm 221 and the second clamping arm 222 can be adjusted, thereby adjusting the width of the clamping space 220 so that the clamping assembly 22 can adapt to teeth of different widths.

[0046] Specifically, the clamping assembly 22 further includes a sliding rod 224, which is disposed at the limiting opening 2230. The first clamping arm 221 and the second clamping arm 222 are slidably mounted on the sliding rod 224. By controlling the first clamping arm 221 and the second clamping arm 222 to slide along the sliding rod 224, the distance between the first clamping arm 221 and the second clamping arm 222 is adjusted to adjust the width of the clamping space 220.

[0047] Furthermore, the clamping assembly 22 further includes an elastic element 225, which is sleeved on the sliding rod 224 and located between the first clamping arm 221 and the second clamping arm 222. One end of the elastic element 225 is connected to the first clamping arm 221, and the other end is connected to the second clamping arm 222. Preferably, the elastic element 225 is a spring. In some modified embodiments, the elastic element 225 can also be an elastic band.

[0048] When the patient's teeth are placed between the first clamping arm 221 and the second clamping arm 222, the distance between the first clamping arm 221 and the second clamping arm 222 increases, the elastic element 225 is stretched, and the elastic element 225 can apply a pulling force to the first clamping arm 221 and the second clamping arm 222 so that the first clamping arm 221 and the second clamping arm 222 move closer to each other, so that the first clamping arm 221 and the second clamping arm 222 clamp the patient's teeth.

[0049] In some modified embodiments, there are two elastic elements 225, one of which is disposed between the first clamping arm 221 and the limiting frame 223, and the other is disposed between the second clamping arm 222 and the limiting frame 223. When the patient's tooth is placed between the first clamping arm 221 and the second clamping arm 222, the distance between the first clamping arm 221 and the second clamping arm 222 increases, and the two elastic elements 225 are compressed. The two elastic elements 225 can exert a pushing force on the first clamping arm 221 and the second clamping arm 222, so that the first clamping arm 221 and the second clamping arm 222 move closer to each other, so that the first clamping arm 221 and the second clamping arm 222 clamp the patient's tooth.

[0050] refer to Figure 6 Along the width direction of the limiting frame 223, the first clamping arm 221 includes a plurality of first clamping blocks 2211 and a first elastic rod 2212 arranged sequentially. The first clamping arm 221 also has a first through hole 2210 that passes through the plurality of first clamping blocks 2211. The first elastic rod 2212 passes through the first through hole 2210, and the two ends of the first elastic rod 2212 are respectively connected to two side walls corresponding to the limiting opening 2230.

[0051] Along the width direction of the limiting frame 223, the second clamping arm 222 includes a plurality of second clamping blocks 2221 and second elastic rods 2222 arranged sequentially. The second clamping arm 222 also has a second through hole 2220 that passes through the plurality of second clamping blocks 2221. The second elastic rod 2222 passes through the second through hole 2220, and the two ends of the second elastic rod 2222 are respectively connected to two side walls corresponding to the limiting opening 2230.

[0052] When the patient's tooth is placed in the clamping space 220 between the first clamping arm 221 and the second clamping arm 222, the contours of the first clamping arm 221 and the second clamping arm 222 can deform to follow the contours of the tooth.

[0053] It is understandable that the patient's teeth have a certain curvature, especially the incisors and canines. When the first clamping arm 221 and the second clamping arm 222 clamp the patient's teeth, the relative positions between the plurality of first clamping blocks 2211 of the first clamping arm 221 and the plurality of second clamping blocks 2221 of the second clamping arm 222 can automatically adjust to follow the contour of the patient's teeth, thereby causing the overall contour of the first clamping arm 221 and the second clamping arm 222 to bend, thereby increasing the contact area with the patient's teeth and improving the stability when clamping the patient's teeth.

[0054] refer to Figure 5 and Figure 7 Furthermore, the end of the connecting arm 21 away from the clamping assembly 22 is rotatably connected to the first clamping arm 11. Rotating the connecting arm 21 relative to the first clamping arm 11 can adjust the position of the clamping assembly 22 relative to the first clamping end 112 to accommodate different patients or expose more of the patient's oral cavity. For example, when the first clamping end 112 and the second clamping end 122 are clamped on the patient's lips and pulled outward, the positions of the first clamping arm 221 and the second clamping arm 222 may be offset relative to the patient's teeth and unable to clamp the patient's teeth. In this case, rotating the connecting arm 21 relative to the first clamping arm 11 can adjust the positions of the first clamping arm 221 and the second clamping arm 222 relative to the patient's teeth, so that the first clamping arm 221 and the second clamping arm 222 can better clamp the patient's teeth.

[0055] Specifically, at least one rotating ring 13 is provided at a predetermined position on the side of the first clamping arm 11 away from the second clamping arm 12. The predetermined position of the rotating ring 13 has a rotating hole 130 arranged along the width direction of the first clamping arm 11. A rotating rod 23 is provided at one end of the connecting arm 21 near the first clamping arm 11. The rotating rod 23 is staggered with the connecting arm 21, and the length extension direction of the rotating rod 23 is preferably the same as the width direction of the first clamping arm 11. The rotating rod 23 passes through the rotating hole 130 of the rotating ring 13, and the rotating rod 23 can rotate within the rotating hole 130. Preferably, the rotating rod 23 is interference-fitted with the rotating hole 130, and the rotating ring 13 can provide a certain preload to the rotating rod 23. After the rotating rod 23 rotates a predetermined angle within the rotating hole 130, the rotating rod 23 is fixed by the friction between the rotating rod 23 and the inner wall of the rotating hole 130 to maintain the position of the connecting arm 21 relative to the first clamping arm 11.

[0056] Preferably, there are two connecting arms 21, which are spaced apart along the width of the first clamping arm 11. The ends of the two connecting arms 21 that are closer to the first clamping arm 11 are respectively connected to the rotating rod 23, and the ends that are farther away from the first clamping arm 11 are respectively connected to the limiting frame 223.

[0057] refer to Figure 1 , Figure 4 as well as Figure 5 The clamping mechanism 10 further includes a clamping rod 14 and an abutment block 15. One end of the clamping rod 14 is connected to the side of the second clamping arm 12 near the first clamping arm 11. The first clamping arm 11 has a clearance opening 113 at a preset position. The end of the clamping rod 14 away from the second clamping arm 12 extends through the clearance opening 113 to the side of the first clamping arm 11 away from the second clamping arm 12. The abutment block 15 is located on the side of the first clamping arm 11 away from the second clamping arm 12, and the abutment block 15 is slidably mounted on the clamping rod 14. In the initial state (without clamping the patient's teeth), there is a large distance between the first clamping end 112 and the second clamping end 122. After shortening the distance between the first clamping end 112 and the second clamping end 122 and clamping the patient's lips, the abutment block 15 is slid along the clamping rod 14 so that the abutment block 15 abuts against the first clamping arm 11 to maintain the distance between the first clamping end 112 and the second clamping end 122.

[0058] Preferably, the distance by which the clearance opening 113 extends along the length direction of the first clamping arm 11 is greater than the distance by which the clearance opening 113 extends along the width direction of the first clamping arm 11.

[0059] Preferably, the first connecting end 111 of the first clamping arm 11 and the second connecting end 121 of the second clamping arm 12 are integrally formed and connected. In the initial state where the patient's teeth are not clamped between the first clamping end 112 and the second clamping end 122, there is a large distance between the first clamping end 112 and the second clamping end 122. When it is necessary to clamp the patient's lips, the first clamping arm 11 and the second clamping arm 12 are squeezed to reduce the distance between the first clamping end 112 and the second clamping end 122, so that the first clamping end 112 and the second clamping end 122 can clamp the patient's teeth. After the distance between the first clamping end 112 and the second clamping end 122 is reduced to a preset distance, the abutment block 15 is slid along the clamping rod 14 toward the first clamping arm 11, so that the abutment block 15 abuts against the first clamping arm 11 to apply a certain pressure to the first clamping arm 11, so as to maintain the state of the first clamping arm 11 and the second clamping arm 12 clamping the patient's lips.

[0060] Specifically, the clamping rod 14 is provided with a threaded structure (not shown in the figure) at a preset position away from the second clamping arm 12, and the abutment block 15 has a screw hole 150 at a preset position. One end of the clamping rod 14 away from the second clamping arm 12 passes through the screw hole 150. Rotating the abutment block 15 relative to the clamping rod 14 can control the abutment block 15 to slide along the length extension direction of the clamping rod 14, so as to adjust the distance between the abutment block 15 and the first clamping arm 11.

[0061] In some modified embodiments, the clamping rod 14 is interference-fitted with the through hole on the abutment block 15. When the abutment block 15 slides along the clamping rod 14 to a preset position, a certain clamping force is applied to the clamping rod 14 by means of the interference fit between the through hole on the abutment block 15 and the clamping rod 14, so as to maintain the position of the abutment block 15 relative to the clamping rod 14.

[0062] refer to Figure 5 Furthermore, the first clamping end 112 of the first clamping arm 11 has an operating port 1120. When the patient's lips are clamped between the first clamping end 112 and the second clamping end 122, part of the patient's lips can be exposed through the operating port 1120, so that the operator can perform appropriate treatment on the patient's lips.

[0063] Furthermore, the fixed lip clamp 100 for lip biopsy and surgery also includes a drug delivery mechanism 30, which includes a mounting rod 31 and a drug delivery tube 32. The mounting rod 31 is mounted on the end of the connecting arm 21 away from the first clamping arm 11. The top of the drug delivery tube 32 is connected to the mounting rod 31, and the bottom of the drug delivery tube 32 extends to the operating port 1120. The end of the drug delivery tube 32 near the mounting rod 31 has a first incision 321, and the end near the operating port 1120 has a second incision 322.

[0064] The mounting rod 31 extends between the two connecting arms 21, with one end of the mounting rod 31 connected to one of the connecting arms 21 and the other end connected to the other connecting arm 21.

[0065] Since the end of the drug delivery tube 32 furthest from the mounting rod 31 extends to the operating port 1120, after medication is injected into the drug delivery tube 32 through the first incision 321, the medication flows out through the second incision 322 to the operating port 1120, thereby enabling the delivery of medication to the patient's lips. The first incision 321 facilitates the operator in adding medication to the drug delivery tube 32, while the second incision 322 facilitates the operator in observing the flow of medication from the drug delivery tube 32.

[0066] refer to Figure 3 Furthermore, the dosing tube 32 has a mounting ring 33 at one end near the mounting rod 31. The mounting ring 33 is sleeved on the mounting rod 31, and the end of the dosing tube 32 away from the first clamping arm 11 is connected to the mounting ring 33. The mounting ring 33 can slide along the length extension direction of the mounting rod 31 and can also rotate around the mounting rod 31 to adjust the position of the end of the dosing tube 32 away from the mounting rod 31 relative to the operating port 1120, facilitating the addition of medication to the lip at different positions within the operating port 1120. In some modified embodiments, the dosing tube 32 is a telescopic tube, specifically comprising two interlocking tubes. Controlling the relative sliding of the two tubes controls the length of the dosing tube 32, thereby adjusting the distance between the second cut 322 of the dosing tube 32 and the operating port 1120 of the first clamping end 112.

[0067] refer to Figure 6The clamping assembly 22 further includes a spreading block 16. The spreading block 16 is adapted to be positioned between the first clamping arm 221 and the second clamping arm 222 to spread the first clamping arm 221 and the second clamping arm 222 when no patient's tooth is placed between them. When the patient's tooth is placed between the first clamping arm 221 and the second clamping arm 222, the spreading block 16 is removed from the clamping space 220, and under the pull of the elastic member 225, the first clamping arm 221 and the second clamping arm 222 clamp the patient's tooth. Similarly, when it is necessary to remove the patient's tooth from the clamping space 220, the spreading block 16 is first placed between the first clamping arm 221 and the second clamping arm 222 to spread them apart, and then the first clamping arm 221 and the second clamping arm 222 are removed from the patient's tooth.

[0068] refer to Figure 8 In some modified embodiments, the fixing mechanism 20 further includes a tension band 24, with both ends of the tension band 24 connected to the two sides of the first clamping end 112 of the first clamping arm 11. The portion of the tension band 24 located between the two ends is situated on the side of the second clamping arm 12 away from the first clamping arm 11. When the patient's lips are clamped between the first clamping end 112 and the second clamping end 122, the portion of the tension band 24 located between the two ends is adapted to fit over the patient's chin to cooperate with the clamping assembly 22, fixing the clamping mechanism 10 in both the upper and lower directions. Preferably, the tension band 24 is a rubber elastic band with a certain degree of elasticity. In some embodiments, a wider sheet-like structure is provided at a preset position on the tension band 24 to increase the contact area with the patient's chin and improve the fixing effect. It should be noted that, in the embodiment where the fixed lip clamp 100 for lip biopsy and surgery has the tension band 24, the fixed lip clamp 100 for lip biopsy and surgery is preferably applied to the patient's lower lip and lower teeth. When the fixed lip clamp 100 for lip biopsy and surgery is applied to the patient's upper lip and upper teeth, the tension band 24 can be secured to the patient's head.
