Description

Technical Field

[0001] This invention relates to the technical field of medical devices, and more specifically, to a fixation device for labial gland biopsy. Background Technology

[0002] Labial gland biopsy is a diagnostic medical procedure used to obtain a small tissue sample from the lip for microscopic pathological examination. This helps determine the nature of any lip lesions and is an important method for diagnosing diseases such as primary Sjögren's syndrome. It is usually performed under local anesthesia. The doctor manually opens the patient's lower lip to expose the surgical site. After cleaning and disinfecting the lip, the doctor injects anesthetic to numb the area and then uses a scalpel, biopsy forceps, or punch to remove the tissue sample. Traditional labial gland biopsy methods are complex, invasive, and have low patient compliance.

[0003] Existing technology discloses a biopsy device for labial glands, including a clamping component comprising a first clamping part and a second clamping part. The first clamping part has a protrusion, and the second clamping part has an exposure area adapted to the protrusion. The first clamping part and the second clamping part are pressed against each other. The protrusion is used to push the mucosa on the inner side of the lip from the outside of the lip into the exposure area. An operating component is rotatably connected to the second clamping part and can be rotated to the position of the exposure area for sampling labial gland tissue from the lip area. In this method, the protrusion pushes the mucosa on the inner side of the lip into the exposure area, so that more labial gland tissue is located in the exposure area. However, it is impossible to accurately observe the biopsy vessels and labial gland area during the operation, resulting in low sampling accuracy and efficiency. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies in terms of low sampling accuracy and efficiency, and to provide a fixation device for labial gland biopsy that allows for real-time observation of the biopsy vessels and labial gland area during the procedure, thereby improving sampling accuracy and efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: a labial gland biopsy fixation device is provided, comprising: an elastic clamp, the clamp including a first elastic arm and a second elastic arm that can rotate relative to each other, the rear end of the first elastic arm being connected to the rear end of the second elastic arm, the front end of the first elastic arm and the front end of the second elastic arm cooperating to clamp the patient's lip, and the front end of the first elastic arm being provided with a biopsy channel for exposing the surgical site; the front end of the second elastic arm being provided with a light source module corresponding to the biopsy channel, at least a portion of the light source module being able to pass through the biopsy channel to lift the surgical site, and the light emitted by the light source module passing through the lifted surgical site.

[0006] In this invention, the labial gland biopsy fixation device involves everting the patient's lip and moving the fixation clamp so that one end of the patient's lower lip is inserted into the clamp, with the second elastic arm positioned on the outer side of the lower lip. Transmitted light from the light source module precisely exposes the inner lip mucosa, avoiding the cumbersome operation of frequent instrument changes and adjustments. After aligning one end of the fixation clamp with the surgical site, pressing the clamp fixes the surgical site between the light source module and the biopsy channel. At least part of the light source module pushes the inner lip mucosa of the surgical site into the biopsy channel, facilitating sampling. Because the patient's lip is fixed inside, the stability of the biopsy area is ensured and bleeding is reduced when the biopsy instrument is inserted through the biopsy channel. Simultaneously, the transmitted light emitted by the light source module illuminates the surgical site, facilitating accurate identification of the biopsy area and enabling minimally invasive procedures, thus improving success rate and safety. The labial gland biopsy fixation device of the present invention integrates fixation, exposure and sampling functions. Through optical transmission technology, it can observe the biopsy blood vessels and labial gland area in real time during the operation, improve sampling accuracy and efficiency, reduce the need for instrument replacement during the operation, shorten the operation time, is minimally invasive and efficient, and shorten the postoperative recovery time.

[0007] Furthermore, the front end of the second elastic arm is provided with a fixing seat, the fixing seat having a cavity, the light source module being installed in the cavity and protruding from the cavity; the front end of the first elastic arm cooperates with the light source module to clamp the patient's lips. The light source module is installed through the cavity of the fixing seat, and at the same time, the light source module directly contacts the lips to transmit light to the surgical site, which can further improve the imaging effect.

[0008] Furthermore, the fixed base has extension wings at both ends on the side away from the second elastic arm, and the extension wings cooperate with the fixed base on the side away from the second elastic arm to form an arc surface. The arc surface can conform to the outer side of the patient's lip, improving comfort. At the same time, it can increase the contact area with the outer side of the patient's lip when everting the lower lip, achieving a better eversion effect, and can also support the lip.

[0009] Furthermore, the light source module is detachably installed within the cavity. The mounting base serves as the supporting foundation for the light source module, and the cavity enables modular installation of the light source module. The light source module and the mounting base are detachably connected, facilitating maintenance, replacement, or sterilization of the instrument.

[0010] Furthermore, the light source module includes a power module, a lamp source, and a lampshade. The power module is located within the cavity and is electrically connected to the lamp source. The lampshade covers the lamp source and is detachably connected to the top of the mounting base. The lampshade covers the outside of the lamp source, providing protection and light transmission. The lampshade is detachable for easy replacement or separation from the mounting clip for disinfection.

[0011] Furthermore, the power module includes a battery, a positive spring electrode, a negative spring electrode, and an electrode connecting plate. The positive and negative spring electrodes are respectively connected to the electrode connecting plate. The positive and negative terminals of the battery can contact the positive and negative spring electrodes, respectively. The lamp source is electrically connected to the electrode connecting plate. The electrode connecting plate provides an installation location for the lamp source and can also be used to connect the battery and the lamp source.

[0012] Furthermore, the power module also includes a cover plate and a power shield. The cover plate, the power shield, and the electrode connection plate together form an installation space. The battery, positive spring electrode, and negative spring electrode are all located within the installation space. The cover plate is detachably connected to the mounting base. By covering the battery, positive spring electrode, and negative spring electrode with the power shield, the components on the cover plate can be protected, and the power module can be modularized.

[0013] Furthermore, it also includes a blocking piece for connecting or disconnecting the circuit. This blocking piece can be pulled out and positioned between the positive terminal and the positive contact electrode of the battery, or between the negative terminal and the negative contact electrode of the battery. As a safety switch, the blocking piece prevents accidental activation of the light source and extends battery life.

[0014] Furthermore, the mounting base includes a connecting platform, a receiving section, and a mounting section connected in sequence. The inner wall of the lampshade fits against the outer wall of the connecting platform, and the bottom of the lampshade abuts against the outer wall of the receiving section. The side wall of the power module abuts against the inner wall of the receiving section, and the bottom of the power module is detachably connected to the mounting section. Through its segmented structural design, the mounting base achieves coordinated fixing of the outer lampshade, the internal power module, and the light source. This allows for both detachable installation of the power module and the light source as a whole and provides protection for the power module and the light source as a whole.

[0015] Furthermore, the inner wall of the mounting section has a slot communicating with the cavity, and the bottom outer periphery of the power module has a protrusion that engages with the slot. Through the cooperation of the protrusion and the slot, the power module can be quickly installed and locked, thereby enabling rapid assembly and disassembly of the power module and the light source as a whole.

[0016] Furthermore, the outer diameter of the connecting platform gradually increases from the end furthest from the receiving section to the end closest to the receiving section. When the lampshade is fitted onto the connecting platform, it achieves self-guiding and tight fit through a gradually tightening fit.

[0017] Furthermore, it also includes a locking mechanism connecting the first elastic arm and the second elastic arm, the locking mechanism being used to lock the opening angle between the first elastic arm and the second elastic arm. When the light source module emits transmitted light to accurately expose the inner lip mucosa, one end of the fixing clip is aligned with the surgical site. Pressing the fixing clip adjusts the opening angle of the fixing clip to fix the surgical site, and then adjusting the locking mechanism to lock the opening angle of the fixing clip, fixing the surgical site exposed between the light source module and the biopsy channel. At this time, the surgeon can release the pressure on the fixing clip, reducing the difficulty of operation. At the same time, the clamping force of the first elastic arm and the second elastic arm can be easily adjusted through the locking mechanism to prevent damage to the patient's lip or unstable clamping, facilitating the performance of the surgery.

[0018] Furthermore, the locking mechanism includes a screw and a nut. One end of the screw is fixedly connected to the second elastic arm, and the other end of the screw passes through the groove of the first elastic arm and is threadedly connected to the nut. The groove provides adjustment freedom, ensuring that the first elastic arm can rotate normally to adapt to different patients' lip thicknesses.

[0019] Furthermore, anti-slip textures are provided between the rear end of the first elastic arm and the locking mechanism, and between the rear end of the second elastic arm and the locking mechanism, respectively, with the two anti-slip textures located on opposite sides of the first and second elastic arms. These anti-slip textures increase surface roughness, generating greater friction between the doctor's hand and the clamp when gripping, facilitating the application of control force to adjust the opening angle of the first and second elastic arms, preventing slippage during operation, and ensuring operational stability during the fixation of the surgical site.

[0020] Furthermore, a counterweight is connected to the rear end of the first elastic arm and the rear end of the second elastic arm. After the first elastic arm and the second elastic arm clamp the patient's lip to fix the biopsy area, the grip on the device is released, and the weight of the counterweight keeps the lower lip everted, freeing the surgeon's hands and facilitating the surgery.

[0021] Compared with the prior art, the beneficial effects of this invention are as follows: (1) The light source module emits transmitted light to accurately expose the inner lip mucosa, allowing real-time observation of the biopsy blood vessels and labial gland area during the operation, improving sampling accuracy and efficiency, and avoiding the tedious operation of frequently changing and adjusting instruments. (2) With the detachable light source module, modular power module and light source, it is easy to quickly assemble the modular power module and light source with the fixing clip or remove the modular power module and light source from the fixing clip, and it is easy to disinfect the fixing clip, lamp cover and modular power module and light source separately. (3) The locking mechanism can fix the surgical site and adjust the appropriate clamping force, reducing the difficulty of operation for the surgeon; (4) The counterweight can keep the lips everted, freeing the surgeon's hands and making it easier for the surgeon to perform the operation.

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting the present patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0026] Example 1 This embodiment is the first embodiment of a labial gland biopsy fixation device, including: as follows Figure 1 , Figure 2 and Figure 5 As shown, the clamp has elasticity and includes a first elastic arm 1 and a second elastic arm 2 that can rotate relative to each other. The rear end of the first elastic arm 1 is connected to the rear end of the second elastic arm 2. The front end of the first elastic arm 1 and the front end of the second elastic arm 2 cooperate to clamp the patient's lips. The front end of the first elastic arm 1 is provided with a biopsy channel 12 for exposing the surgical site. The front end of the second elastic arm 2 is provided with a light source module 6 corresponding to the biopsy channel 12. At least a portion of the light source module 6 can pass through the biopsy channel 12 to lift the surgical site. The light emitted by the light source module 6 passes through the lifted surgical site.

[0027] In use, the aforementioned labial gland biopsy fixation device involves everting the patient's lip and moving the fixation clamp so that the patient's lower lip is inserted into one end of the clamp, with the second elastic arm 2 positioned on the outer side of the lower lip. Transmitted light from the light source module 6 precisely exposes the inner lip mucosa, avoiding the cumbersome operation of frequent instrument changes and adjustments. When one end of the fixation clamp is aligned with the surgical site, pressing the clamp fixes the surgical site between the light source module 6 and the biopsy channel 12. At least part of the light source module 6 pushes the inner lip mucosa of the surgical site into the biopsy channel 12, facilitating sampling. Because the patient's lip is fixed inside, the stability of the biopsy area is ensured when the biopsy instrument is inserted through the biopsy channel 12 for sampling, reducing bleeding. Simultaneously, the transmitted light from the light source module 6 illuminates the surgical site, facilitating precise confirmation of the biopsy area and enabling minimally invasive procedures, thus improving success rate and safety. The labial gland biopsy fixation device of this embodiment integrates fixation, exposure and sampling functions. Through optical transmission technology, it can observe the biopsy blood vessels and labial gland area in real time during the operation, improve sampling accuracy and efficiency, reduce the need for instrument replacement during the operation, shorten the operation time, is minimally invasive and efficient, and shorten the postoperative recovery time.

[0028] In this embodiment, the first elastic arm 1 and the second elastic arm 2 can be clamped under external force and open by their own elasticity. It should be noted that the first elastic arm 1 and the second elastic arm 2 can be hinged by a spring hinge, which can rotate and clamp under external force and return to open under the spring force; the first elastic arm 1 and the second elastic arm 2 can also be hinged by a flexible hinge, which is an elastic support structure that achieves frictionless and backlash-free transmission through the elastic deformation of the material, and has advantages such as high precision and compactness.

[0029] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the front end of the second elastic arm 2 is provided with a fixing seat 3, which has a cavity. The light source module 6 is installed in the cavity and protrudes from the cavity. The front end of the first elastic arm 1, in conjunction with the light source module 6, clamps the patient's lips. Specifically, the front end of the first elastic arm 1 is provided with a pressure plate 11, and a biopsy channel 12 is opened on the pressure plate 11. When the pressure plate 11, in conjunction with the fixing seat 3, clamps the patient's lips, the light source module 6 contacts the outer side of the lip and pushes the surgical site into the biopsy channel 12. The pressure plate 11 and the fixing seat 3 work together to apply pressure evenly to clamp the lips, reducing tissue compression damage. The biopsy channel 12 provides a direct access path for surgical instruments and accurately positions and fixes the surgical site, improving operational efficiency. At the same time, the light source module 6 directly contacts the lips to transmit light to the surgical site, which can further improve the imaging effect. It should be noted that the light source module 6 can also be directly fixed on the second elastic arm 2.

[0030] The top of the light source module 6 can be fully inserted into the biopsy channel 12. The orthographic projection of the pressure plate 11 on the outer periphery of the biopsy channel 12 overlaps with the fixing base 3. When storing, the first elastic arm 1 and the second elastic arm 2 can be pressed to make the top of the light source module 6 completely pass through the biopsy channel 12 and make the pressure plate 11 contact the surface of the fixing base 3, which can reduce the storage space and at the same time avoid damage to the light source module 6 by the biopsy channel 12 when pressing the fixing clip.

[0031] The light source module 6 includes a lamp source 63 for emitting transmitted light, which can be used to transmit light through the biopsy area to expose the inner lip mucosa for easier surgery. The lamp source 63 can be directly attached to the outer side of the patient's lip to achieve good transmission effect.

[0032] The light source module 6 may also include a lampshade 7 that covers the light source 63, protecting the light source 63. During use, the lampshade 7 contacts the outer side of the patient's lips. The lampshade 7 allows for more concentrated light, increases brightness, and reduces energy waste.

[0033] The biopsy channel 12 is rectangular, and the top of the light source module 6 is also rectangular. The labial gland tissue itself is soft and easy to move. When the tissue is lifted in a rectangular manner, a tight surgical plane is formed in the central area of ​​the rectangle, which can provide the doctor with a stable and precise operating platform. Furthermore, the width and length of the rectangle provide sufficient field of vision while ensuring that the size of the tissue to be removed is sufficient, making it easier to achieve the required number of glands for diagnosis.

[0034] The inner walls of both openings of the biopsy channel 12 are arc-shaped. During implementation, the pressure plate 11 presses against the inner side of the lip, exerting force on the inner side of the lip. The arc-shaped inner opening of the biopsy channel 12 can prevent scratching the inner side of the lip when clamping, and the arc-shaped outer opening of the biopsy channel 12 can facilitate the insertion of biopsy instruments.

[0035] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the fixed seat 3 has extended wings 341 at both ends on the side away from the second elastic arm 2, which form an arc surface 34 with the side of the fixed seat 3 away from the second elastic arm 2. This can fit the outer side of the patient's lips, improving comfort. At the same time, it can increase the contact area with the outer side of the patient's lips when everting the lower lip, achieving a better eversion effect, and can also support the lips.

[0036] Example 2 This embodiment is the second embodiment of the labial gland biopsy fixation device. This embodiment is similar to the first embodiment, except that the light source module 6 is detachably installed in the cavity. The fixing base 3 serves as the supporting foundation for the light source module 6. The cavity enables the modular installation of the light source module 6, and the detachable design of the light source module 6 facilitates the maintenance, replacement, or sterilization of the instrument.

[0037] like Figure 1 , Figures 3 to 5 As shown, the light source module includes a power module, a lamp source 63, and a lamp cover 7. The power module is located inside the cavity and is electrically connected to the lamp source 63. The lamp cover 7 covers the lamp source and is detachably connected to the top of the mounting base 3. The lamp cover 7 covers the outside of the lamp source 63, providing protection and light transmission. The lamp cover 7 can improve the light concentration, reduce light scattering, and act as a light guide to enhance the transmission effect in the surgical area, while preventing the lamp source 63 from being contaminated or damaged. Specifically, the lamp cover 7 is a transparent medical-grade plastic structure to ensure light transmission. The lamp cover 7 is detachable for easy replacement or separate sterilization from the mounting clip.

[0038] The lampshade 7 has an outward protrusion at the top, which can push the patient's inner lip mucosa into the biopsy channel 12 from the outside of the lip, further exposing more lip gland tissue to the exposure area.

[0039] like Figures 3 to 5 As shown, the power module includes a battery 65, a positive spring electrode 66, a negative spring electrode 67, and an electrode connecting plate 64. The positive spring electrode 66 and the negative spring electrode 67 are respectively connected to the electrode connecting plate 64. The positive and negative terminals of the battery 65 can contact the positive spring electrode 66 and the negative spring electrode 67, respectively. The lamp source 63 is electrically connected to the electrode connecting plate 64. The electrode connecting plate 64 provides an installation position for the lamp source 63 and can also be used to connect the battery 65 and the lamp source 63.

[0040] like Figure 4 , Figure 5As shown, the power module also includes a cover plate 61 and a power cover 62. The cover plate 61, the power cover 62, and the electrode connection plate 64 form an installation space. The battery 65, the positive spring electrode 66, and the negative spring electrode 67 are all located within the installation space. The cover plate 61 is detachably connected to the fixing base 3. By covering the battery 65, the positive spring electrode 66, and the negative spring electrode 67 with the power cover 62, it can protect the components on the cover plate 61 and also realize the modularity of the power module, the electrode connection plate 64, and the lamp source 63 on it. In this embodiment, the power module and the lamp source 63 as a whole enter the cavity from the bottom of the fixing base 3. Pressing the cover plate 61 to connect with the fixing base 3 can realize modular installation. When pressing down from the top of the light source module 6 until the cover plate 61 is separated from the fixing base 3, modular disassembly can be realized. When it is necessary to replace the light source module 6 or disassemble the light source module 6 for device disinfection, the replacement process can be simplified and convenience can be improved.

[0041] like Figures 3 to 5 As shown, it also includes a blocking piece 68 for connecting or disconnecting the circuit. The blocking piece 68 is removable and positioned between the positive terminal and the positive spring electrode 66 of the battery 65, or between the negative terminal and the negative spring electrode 67 of the battery 65. The circuit is switched on and off by pulling the blocking piece 68. When the blocking piece 68 is inserted, the circuit is disconnected and the lamp source 63 is extinguished; when the blocking piece 68 is removed, the circuit is connected and the lamp source 63 illuminates. The blocking piece 68 acts as a safety switch, preventing accidental activation of the lamp source and extending the battery life of the battery 65.

[0042] Specifically, such as Figure 4 As shown, the power supply cover 62 and the mounting base 3 are each provided with a corresponding slot 35, into which the barrier plate 68 is inserted. The slot 35 guides the barrier plate 68 to be inserted and removed along a specific path, ensuring that the barrier plate 68 is accurately positioned between the battery 65 and the electrode, enabling circuit control, preventing misalignment or detachment of the barrier plate 68, and enhancing safety and user experience. Simultaneously, when the light source module 6 is installed in the cavity of the mounting base 3 and surgery is not performed using the device, the barrier plate 68 can be inserted through the slot 35 to cut off the circuit and extend the battery 65's lifespan.

[0043] like Figure 5As shown, the mounting base 3 includes a connecting platform 31, a receiving section 32, and a mounting section 33 connected in sequence. The inner wall of the lampshade 7 fits against the outer wall of the connecting platform 31, and the bottom of the lampshade 7 abuts against the outer wall of the receiving section 32. The side wall of the power module abuts against the inner wall of the receiving section 32, and the bottom of the power module is detachably connected to the mounting section 33. Through its segmented structural design, the mounting base 3 achieves coordinated fixation of the outer lampshade 7 with the internal power module and light source 63. The connecting platform 31 provides a guiding and supporting surface for the lampshade 7. The receiving section 32 serves as both a limit for the lampshade 7 and a mounting compartment for the power module. Specifically, the mounting section 33 is connected to the cover plate 61, thereby encapsulating the power module and light source 63 within the mounting base 3. This allows for the detachable installation of the power module and light source 63 as a whole, while also providing overall protection for the power module and light source 63.

[0044] like Figure 2 , Figure 5 As shown, the inner wall of the mounting section 33 has a slot 331 communicating with the cavity, and the bottom of the power module (cover plate 61) has a protrusion 611 on its outer periphery that engages with the slot 331. Through the cooperation of the protrusion 611 and the slot 331, the power module (cover plate 61) can be quickly installed and locked, thereby enabling quick assembly and disassembly of the power module and the lamp source 63 as a whole. Specifically, the cooperation of the protrusion 611 and the slot 331 requires applying a certain force to the power module and the lamp source 63 for disassembly, preventing the installed power module and lamp source 63 from detaching from the cavity.

[0045] like Figure 4 , Figure 5 As shown, the outer diameter of the connecting platform 31 gradually increases from the end furthest from the receiving section 32 to the end closest to the receiving section 32. When the lamp cover 7 is fitted onto the connecting platform 31, the gradually tightening fit achieves self-guiding and tight contact, forming a wedge-tight effect. This simplifies the installation process of the lamp cover 7 and ensures that the contact area between the lamp cover 7 and the connecting platform 31 is maximized, resulting in a more stable connection and effectively preventing the lamp cover 7 from accidentally loosening during use. At the same time, by fitting the lamp cover 7 onto the connecting platform 31, it helps to prevent light leakage from gaps, ensuring that the light is more concentrated on the biopsy area.

[0046] In this embodiment of the labial gland biopsy fixation device, during assembly, the barrier 68 of the light source module 6 is removed, and then the modular power module and lamp source 63 are pressed into the cavity from the bottom of the second elastic arm 2, so that the protrusion 611 on the outer periphery of the cover plate 61 is inserted into the slot 331. At this time, the slot 35 of the fixing base 3 is aligned with the slot 35 on the power cover 62. The barrier 68 is inserted from the slot 35 to disconnect the circuit, and then the lamp cover 7 is put on from the top of the fixing base 3. During disassembly, the lamp cover 7 is pulled out from the top of the fixing base 3, the barrier 68 is removed, the modular power module and lamp source 63 are pressed, the protrusion 611 is dislodged from the slot 331, the light source module 6 is removed from the cavity, and then the barrier 68 is inserted between the battery 65 and the electrode of the light source module 6.

[0047] Example 3 This embodiment is a third embodiment of the labial gland biopsy fixation device. This embodiment is similar to Embodiment 1 or Embodiment 2, except that it further includes a locking mechanism 5 connecting the first elastic arm 1 and the second elastic arm 2. The locking mechanism 5 is used to lock the opening angle between the first elastic arm 1 and the second elastic arm 2. Figure 1 , Figure 2 As shown, the locking mechanism 5 includes a screw 51 and a nut 52. One end of the screw 51 is fixedly connected to the second elastic arm 2, and the other end of the screw 51 passes through the groove 13 of the first elastic arm 1 and is threadedly connected to the nut 52. Rotating the nut 52 adjusts its position on the screw 51. Specifically, when the nut 52 is rotated and moves upward along the screw 51, the first elastic arm 1 and the second elastic arm 2 move away from each other under the action of elastic force, and the opening angle of the clamp gradually increases. When the clamping of the patient's lip is completely released, the rotation of the nut 52 stops. The groove 13 ensures that the first elastic arm 1 can rotate and open normally. During surgery, when the light source module emits transmitted light to accurately expose the inner lip mucosa, one end of the clamp is aligned with the surgical site. When the first elastic arm 1 and the second elastic arm 2 are pressed to clamp and fix the surgical site, the groove 13 provides adjustment freedom to adapt to different lip thicknesses. Reverse rotation of the nut 52 moves it downward along the screw 51. When nut 52 abuts against the first elastic arm 1 and clamps the lip with the first elastic arm 1 and the second elastic arm 2, rotation of nut 52 stops. Since nut 52 is threadedly connected to screw 51, screw 51 can be used to limit nut 52 and prevent nut 52 from falling off, thereby limiting and maintaining the opening angle of the first elastic arm 1 and the second elastic arm 2, fixing the surgical site exposed between the light source module 6 and the biopsy channel 12. At this time, the surgeon can release the pressure on the fixation clamp, reducing the difficulty of operation. At the same time, the clamping force of the first elastic arm 1 and the second elastic arm 2 can be easily adjusted through the locking mechanism 5 to prevent damage to the patient's lip or unstable clamping, facilitating the surgery. It should be noted that screw 51 and the second elastic arm 2 can be integrally formed.

[0048] Among them, nut 52 is a wing nut, which is convenient for manual operation. The surgeon can press the first elastic arm 1 and the second elastic arm 2 with one hand to hold the patient's hand, and rotate the wing nut with the other hand until it is pressed against the first elastic arm 1.

[0049] like Figure 1 , Figure 2 As shown, anti-slip textures 4 are provided between the rear end of the first elastic arm 1 and the locking mechanism 5, and between the rear end of the second elastic arm 2 and the locking mechanism 5, respectively. The two anti-slip textures 4 are located on the sides of the first elastic arm 1 and the second elastic arm 2 that are far apart from each other. The anti-slip textures 4 increase the surface roughness, generating greater friction between the doctor's hand and the clamp when holding it. This facilitates the application of control force to adjust the opening angle of the first elastic arm 1 and the second elastic arm 2, prevents slippage during operation, and ensures operational stability during the fixation of the surgical site.

[0050] The fixation clip can be made of medical-grade polymer material, which greatly reduces the risk of allergies or adverse tissue reactions in patients and ensures basic surgical safety. In addition, polymer material is a natural electrical insulator, which can effectively avoid the risk of short circuit in the light source module 6 circuit, protect electronic components, and prevent any possible microcurrent stimulation to the patient. Furthermore, the polymer material structure is easy to process, and the first elastic arm 1 and the second elastic arm 2 can be manufactured to fit the curvature of the lips more closely. Moreover, the cost of large-scale production is relatively low. If it is for single use, it can effectively prevent cross-infection and simplify the hospital disinfection process. If it is for reuse, its initial purchase cost is usually lower than that of metal instruments of the same precision.

[0051] The clamp can also be made of medical-grade metal materials, which can maintain precise and stable clamping force after repeated use and can withstand the strict disinfection and sterilization procedures of hospitals, making it more economical in the long run.

[0052] The fixing clamp can also be made of a combination of medical-grade polymer material structure and medical-grade metal material structure. The pressure plate 11 and the fixing seat 3 are made of medical-grade polymer material structure, while the main body of the first elastic arm 1 and the main body of the second elastic arm 2 are made of medical-grade metal material structure, which has both stable clamping force and economy.

[0053] Example 4 This embodiment is the fourth embodiment of the labial gland biopsy fixation device. This embodiment is similar to Embodiment 1, Embodiment 2, or Embodiment 3, except that, as Figure 1 , Figure 2 As shown, a counterweight 8 is connected to the rear end of the first elastic arm 1 and the rear end of the second elastic arm 2. After the first elastic arm 1 and the second elastic arm 2 clamp the patient's lip to fix the biopsy area, the patient can release the grip on the device and use the weight of the counterweight 8 to keep the lower lip everted, freeing the surgeon's hands and making it easier for the surgeon to perform the operation.

[0054] The counterweight seat 8 features a hollow design, which can be filled with counterweight materials, such as stainless steel pellets, to adjust the appropriate weight range.

[0055] In this embodiment, the labial gland biopsy fixation device is used by rotating the nut 52 so that it moves upward along the screw 51 until the distance between the first elastic arm 1 and the second elastic arm 2 is sufficient for the patient's lip to enter. The fixation clamp is moved so that the patient's lower lip extends into one end of the fixation clamp, with the second elastic arm 2 located on the outside of the lower lip. The lip is everted by the first elastic arm 1 and the second elastic arm 2. When one end of the fixation clamp is aligned with the surgical site, transmitted light is emitted through the light source module 6 to accurately expose the inner lip mucosa, avoiding the tedious operation of frequently changing and adjusting instruments. The fixation clamp is pressed to adjust the opening angle of the fixation clamp to fix the surgical site. Then, the nut 52 is rotated in the opposite direction so that it moves downward along the screw 51. When the nut 52 abuts against the first elastic arm 1 and the first elastic arm 1 and the second elastic arm 2 press and clamp the lip, the rotation of the nut 52 is stopped to maintain the fixation of the biopsy area. The surgical site is fixed and exposed between the lamp cover 7 and the biopsy channel 12. The counterweight 8 keeps the patient's lip everted, freeing the surgeon's hands and facilitating the operation. Because the inside of the patient's lip is fixed, the biopsy instrument is inserted through the biopsy channel 12 to take a sample, which ensures the stability of the biopsy area and reduces bleeding. At the same time, the light source module 6 emits transmitted light to the surgical site, which facilitates real-time observation of the biopsy blood vessels and labial gland area, improves sampling efficiency and accuracy, and enables minimally invasive operation, thereby improving the success rate and safety.

[0056] Clinical data show that when using the labial gland biopsy fixation device of this invention for labial gland biopsy sampling, the surgical incision only needs to be 3-5mm, no sutures are required, patients can eat 2 hours after the operation, and recover in 3 days, which significantly reduces patient suffering. Moreover, the sample qualification rate is as high as 98.5%, and the incidence of serious complications is extremely low (such as bleeding and infection less than 1%).

For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.
