Description

Technical Field

[0001] This invention relates to the field of medical devices, and more specifically, to an integrated colposcope biopsy forceps with adjustable tension. Background Technology

[0002] In gynecological clinical diagnosis, colposcopy is an important means of screening and diagnosing cervical, vaginal, and vulvar lesions. Biopsy, as a key step in this examination, requires the use of specialized instruments to obtain tissue samples from lesions for subsequent pathological analysis, providing a basis for disease diagnosis. This process places strict requirements on the precision, stability, and functional adaptability of the instruments. The instruments must be able to adapt to the differences in vaginal anatomy among different patients, while ensuring that damage to surrounding normal tissues is minimized when obtaining tissue samples, so as to provide reliable pathological evidence for subsequent diagnosis and treatment.

[0003] With the development of medical technology, clinicians have placed higher demands on the efficiency and safety of colposcopy biopsy procedures. On the one hand, different patients have different vaginal wall toughness and lesion locations. For example, postmenopausal patients have tougher vaginal tissue, and obese patients' vaginal walls are more likely to obscure the lesion area. This requires biopsy instruments to have flexible adjustment capabilities to stably expose the lesion site and perform precise operations. On the other hand, bleeding often occurs after biopsy, requiring timely hemostasis. At the same time, it is necessary to maintain a clear field of vision and avoid infection during the operation. These requirements make it difficult for single-function biopsy instruments to meet the integrated and efficient requirements of clinical operations.

[0004] Currently, existing biopsy instruments have many shortcomings in practical applications. The opening and closing angle of most instruments cannot be reliably limited after being fixed or adjusted, making it difficult to stabilize the operation position when dealing with different patients' vaginal structures. The vibration of the forceps can easily affect the sampling accuracy. The design of the connection between the lever, forceps, and tube of some instruments is unreasonable, and the transmission of operating force is prone to deviation. This can lead to poor force control when clamping tissue, which may cause tissue slippage or excessive compression, affecting sample quality. Summary of the Invention

[0005] In view of the problem that most instruments in the prior art cannot reliably limit the opening and closing angle of the forceps after it is fixed or adjusted, the purpose of this invention is to provide an integrated colposcope biopsy forceps with adjustable tension.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] An adjustable tension integrated colposcope biopsy forceps includes a first forceps body, a second forceps body and a first forceps tube rotatably mounted on the first forceps body, the first forceps tube being connected to the second forceps tube via a connecting assembly, a first pull rod slidably mounted inside the first forceps tube, the first pull rod being connected and engaged with the second forceps body, a second pull rod slidably mounted inside the second forceps tube and detachably connected to the first pull rod, a pair of pull tabs rotatably mounted on the second pull rod, a pair of clamping tabs rotatably mounted at the ends of the pair of pull tabs away from the second pull rod, and the connection point of the two clamping tabs being rotatably mounted on the end of the second forceps tube;

[0008] The second clamp tube is provided with a switching component, which includes a rotating drum. The rotating drum is equipped with a functional component, which is used to perform sampling, hemostasis and disinfection of the pathological site.

[0009] A limit component is provided at the connection between the first clamp and the second clamp, and the limit component is used to limit the position adjustment of the first clamp and the second clamp.

[0010] Optionally, the connecting assembly includes a threaded groove formed on the first clamp tube, and a threaded sleeve is fitted on the second clamp tube, the threaded sleeve cooperating with the threaded groove to fix the second clamp tube on the first clamp tube.

[0011] Optionally, the rotating drum is rotatably mounted on the second clamp tube.

[0012] Optionally, the rotating drum is provided with a set of insertion slots, the second clamp tube is provided with a movable slot, an insertion block is slidably installed in the movable slot, a first spring is fixedly installed on the insertion block, the end of the first spring away from the insertion block is fixedly connected to the inner wall of the movable slot, and the insertion block is adapted to the insertion slot.

[0013] Optionally, the functional component includes a pair of mounting housings slidably mounted on a rotating drum, a motor fixedly mounted inside the mounting housing, a threaded rod mounted on the output shaft of the motor, a movable plate threadedly connected to the threaded rod, and the movable plate slidably connected to the inner wall of the mounting housing.

[0014] Optionally, a cutting blade is fixedly mounted on a movable plate inside the mounting housing on one side, and the cutting blade is slidably connected to the inner wall of the mounting housing.

[0015] Optionally, a hemostatic electrode is fixedly mounted on a movable plate inside the mounting housing on the other side, and the hemostatic electrode is slidably connected to the inner wall of the mounting housing.

[0016] Optionally, an insert block is fixedly installed on the rotating drum, the insert block has an installation groove, a second spring is fixedly installed in the installation groove, a limiting protrusion is fixedly installed at the other end of the second spring, the limiting protrusion is slidably connected to the inner wall of the installation groove, and a slot that mates with the insert block is provided on the mounting shell, and a limiting hole is provided in the slot.

[0017] Optionally, the rotating drum is provided with a disinfection channel, and an inlet pipe connected to the disinfection channel is installed on the rotating drum. An installation block is fixedly installed inside the disinfection channel, and a main shaft is fixedly installed on the installation block. A sliding ring is slidably installed on the main shaft, and a third spring is fixedly installed on the sliding ring. The other end of the third spring is fixedly connected to the main shaft, and a rotating impeller is rotatably installed on the sliding ring.

[0018] Optionally, the limiting component includes a insertion hole formed on the first clamp body, a mating block detachably installed in the insertion hole, a rotating shaft threadedly connected to the mating block, the rotating shaft passing through the first clamp body and the second clamp body, and an abutment block fixedly installed at the end of the rotating shaft. The abutment block is a concave block.

[0019] Compared with the prior art, the technical solution provided by this invention has at least the following beneficial effects:

[0020] In the above solution, the first clamp body and the second clamp body of the present invention achieve the opening and closing action through a rotatable connection. The opening and closing angle can be adjusted according to the operation requirements to adapt to different operation scenarios. The first clamp tube is rotatably mounted on the first clamp body and can adjust its angle with the movement of the first clamp body. At the same time, it is connected to the second clamp tube through a connecting component, which ensures the continuity and stability of the overall structure and enables the effective transmission of operating force. The first pull rod slides in the first clamp tube and cooperates with the second clamp body. When the second clamp body moves, it can drive the first pull rod to slide in the first clamp tube. Since the second pull rod is detachably connected to the first pull rod, the sliding of the first pull rod can drive the second pull rod to slide synchronously in the second clamp tube. This transmission method can accurately transmit operating force, providing power for the subsequent movement of the clamping plates; a pair of pull plates rotatably mounted on the second pull rod will rotate when the second pull rod slides, thereby driving the clamping plate at the end away from the second pull rod to rotate around the mounting point on the second clamp tube, realizing the opening and closing of the clamping plate. Through the opening and closing of the clamping plate, the tissue around the pathological site can be stably clamped, creating good conditions for the operation of subsequent functional components and avoiding the impact of tissue movement on the accuracy of sampling, hemostasis and other operations.

[0021] The connecting assembly secures the first and second clamping tubes via a threaded connection. When connecting the first and second clamping tubes, align the second clamping tube with the first clamping tube, ensuring the threaded sleeve on the second clamping tube corresponds to the threaded groove on the first clamping tube. Then, rotate the threaded sleeve, allowing it to rotate within the threaded groove and gradually tighten. The interaction force between the threads firmly fixes the second clamping tube to the first clamping tube. This threaded connection method features a secure connection and easy disassembly, ensuring no relative movement between the first and second clamping tubes during operation and guaranteeing effective force transmission. Furthermore, when replacing or repairing the second clamping tube, simply reverse the rotation of the threaded sleeve to disassemble it, improving equipment maintenance convenience.

[0022] This structure is primarily used for positioning the rotating drum after it has rotated, preventing accidental rotation during operation. Before the drum rotates, the insertion block extends one end of its movable slot under the force of a first spring. When the drum rotates, the insertion slots on the drum rotate with it. When a slot rotates to the position corresponding to the insertion block, the insertion block inserts into that slot under the force of the first spring, thus fixing the drum in its current position and achieving positioning. At this time, the functional components mounted on the drum are also fixed in their corresponding working positions, ensuring stable operation. When it is necessary to rotate the drum again to switch functional components, the operator pulls the insertion block, causing it to retract into its movable slot against the force of the first spring, allowing the drum to continue rotating until the next insertion slot aligns with the insertion block. The insertion block then pops out of its slot again, achieving positioning. This positioning method is simple, reliable, and effectively ensures the stability of the drum during operation, improving operational accuracy. Attached Figure Description

[0048] like Figures 1 to 12As shown, this embodiment of the invention provides an integrated colposcope biopsy forceps with adjustable tension, including a first forceps body 10, a second forceps body 11 rotatably mounted on the first forceps body 10, a first forceps tube 12 rotatably mounted on the first forceps body 10, the first forceps tube 12 being connected to the second forceps tube 13 via a connecting assembly 20, a first pull rod 14 cooperating with the second forceps body 11 being slidably mounted inside the first forceps tube 12, a second pull rod 15 detachably connected to the first pull rod 14 being slidably mounted inside the second forceps tube 13, a pair of pull tabs 16 being rotatably mounted at the end of the second pull rod 15, and a pair of clamping tabs 17 being rotatably mounted at the end of each pair of pull tabs 16 away from the second pull rod 15.

[0049] A switching assembly 30 is located on the second forceps tube 13. The switching assembly 30 includes a rotating cylinder 31 for mounting functional components, which are used for sampling, hemostasis, and disinfection of pathological sites. The rotating cylinder 31 is sleeved over the second forceps tube 13. One end of the second forceps tube 13 extends beyond the rotating cylinder 31, and the connection point of two clamping plates 17 is rotatably mounted at the end of the second forceps tube 13.

[0050] A limiting component is provided at the connection between the first clamp 10 and the second clamp 11 to limit the position of the clamp after adjustment.

[0051] like Figures 1 to 6 As shown, the first clamp body 10 and the second clamp body 11 in this invention are connected by rotation to realize the opening and closing action. The opening and closing angle can be adjusted according to the operation requirements to adapt to different operation scenarios. The first clamp tube 12 is rotatably mounted on the first clamp body 10 and can adjust its angle with the movement of the first clamp body 10. At the same time, it is connected to the second clamp tube 13 through the connecting component 20, which ensures the continuity and stability of the overall structure and enables the operating force to be effectively transmitted.

[0052] The first pull rod 14 slides within the first clamp tube 12 and engages with the second clamp body 11. When the second clamp body 11 moves, it can drive the first pull rod 14 to slide within the first clamp tube 12. Since the second pull rod 15 is detachably connected to the first pull rod 14, the sliding of the first pull rod 14 can drive the second pull rod 15 to slide synchronously within the second clamp tube 13. This transmission method can accurately transmit operating force, providing power for the subsequent movement of the clamping plate 17.

[0053] A pair of pull tabs 16 are rotatably mounted on the second pull rod 15. When the second pull rod 15 slides, the pull tabs 16 rotate, which in turn drives the clamping tab 17, located away from the second pull rod 15, to rotate around the mounting point on the second clamp tube 13. This allows the clamping tab 17 to open and close. By opening and closing the clamping tab 17, the tissue surrounding the pathological site can be stably clamped, creating favorable conditions for the operation of subsequent functional components and preventing tissue movement from affecting the accuracy of sampling, hemostasis, and other operations. The similar structure of the clamping tab 17 and the pull tab 16 is existing technology and will not be described in detail here.

[0054] The rotating cylinder 31 in the switching assembly 30 is installed on the second clamp tube 13. The rotating cylinder 31 can be rotated according to the operation requirements to switch different functional components to the working position, so as to meet the different operation requirements of sampling, hemostasis and disinfection of pathological sites, without the need for frequent instrument changes and improving operation efficiency.

[0055] like Figures 11 to 12 As shown, the limiting component is located at the connection between the first clamp 10 and the second clamp 11. When the first clamp 10 and the second clamp 11 are adjusted to a suitable opening and closing angle, the limiting component can limit the relative position of the two, prevent the clamp angle from changing unexpectedly during operation, ensure the stability and accuracy of operation, avoid the impact of clamp shaking on the operation effect, and reduce the operation risk.

[0056] like Figures 1 to 6 As shown, the connecting assembly 20 includes a threaded groove 21 formed on the first clamp tube 12, and a threaded sleeve 22 is fitted on the second clamp tube 13. The threaded sleeve 22 can cooperate with the threaded groove 21 to fix the second clamp tube 13 on the first clamp tube 12.

[0057] The connecting assembly 20 secures the first clamp tube 12 and the second clamp tube 13 via a threaded connection. When connecting the first clamp tube 12 and the second clamp tube 13, the second clamp tube 13 is aligned with the first clamp tube 12, so that the threaded sleeve 22 on the second clamp tube 13 corresponds to the threaded groove 21 on the first clamp tube 12. Then, the threaded sleeve 22 is rotated, and it rotates within the threaded groove 21, gradually tightening. Through the interaction force between the threads, the second clamp tube 13 is firmly fixed to the first clamp tube 12. This threaded connection method features a strong connection and convenient disassembly, ensuring that there is no relative movement between the first clamp tube 12 and the second clamp tube 13 during operation, ensuring effective transmission of operating force. Furthermore, when the second clamp tube 13 needs to be replaced or repaired, it can be disassembled simply by rotating the threaded sleeve 22 in the opposite direction, improving the convenience of equipment maintenance.

[0058] The switching assembly 30 includes a rotating cylinder 31, which is rotatably mounted on a second clamp tube 13. The rotating cylinder 31 has a set of insertion slots 32, and the second clamp tube 13 has a movable slot 33. An insertion block 35 is slidably installed in the movable slot 33, and a first spring 34 is fixedly installed on the insertion block 35. The end of the first spring 34 away from the insertion block 35 is fixedly connected to the inner wall of the movable slot 33. The insertion block 35 is adapted to the insertion slots 32. There are four insertion slots 32, which are arranged around the outer periphery of the rotating cylinder 31.

[0059] This structure is mainly used to achieve positioning of the rotating drum 31 after rotation, preventing accidental rotation of the rotating drum 31 during operation. Before the rotating drum 31 rotates, the insertion block 35 extends one end of the movable slot 33 under the elastic force of the first spring 34. When the rotating drum 31 rotates, the insertion slot 32 on the rotating drum 31 rotates with the rotating drum 31. When a certain insertion slot 32 rotates to the position corresponding to the insertion block 35, the insertion block 35 will be inserted into the insertion slot 32 under the elastic force of the first spring 34, thereby fixing the rotating drum 31 in the current position and achieving positioning of the rotating drum 31. At this time, the functional components installed on the rotating drum 31 are also fixed in the corresponding working position to ensure that the functional components can work stably. When it is necessary to rotate the rotating drum 31 again to switch functional components, the operator pulls the insertion block 35, so that the insertion block 35 retracts into the movable slot 33 against the elastic force of the first spring 34, so that the rotating drum 31 can continue to rotate until the next insertion slot 32 is aligned with the insertion block 35, and the insertion block 35 pops out of the insertion slot 32 again to achieve positioning. This positioning method is simple and reliable, and can effectively ensure the stability of the rotating drum 31 during operation and improve the accuracy of operation.

[0060] like Figure 2 , Figures 7 to 10 As shown, the functional component includes a pair of mounting housings 41 slidably mounted on the rotating drum 31. The two mounting housings 41 are located on opposite sides of the rotating drum 31. The mounting housings 41 have slots, and a motor 42 is fixedly mounted in the slots of the mounting housings 41. A threaded rod 43 is fixedly mounted on the output shaft of the motor 42. A movable plate 44 is threadedly connected to the threaded rod 43. The movable plate 44 is slidably connected to the inner wall of the slot of the mounting housing 41.

[0061] The functional components are driven by motor 42 to realize the movement of related parts to meet different functional requirements (the first clamp body 10 has integrated control buttons, which can be adjusted to open the switches of related parts as needed). The mounting housing 41 provides space for the installation and protection of components such as motor 42, threaded rod 43, and movable plate 44. The mounting housing 41 is slidably mounted on the rotating drum 31. When a related operation is required, pressing the relevant control button starts the motor 42 inside the mounting housing 41. The output shaft of the motor 42 drives the threaded rod 43 to rotate. Since the movable plate 44 is threadedly connected to the threaded rod 43, and the movable plate... The movable plate 44 is slidably connected to the inner wall of the mounting housing 41. The rotation of the threaded rod 43 is converted into the linear sliding of the movable plate 44 along the inner wall of the mounting housing 41. The sliding of the movable plate 44 can drive the relevant actuators mounted on it to move synchronously, thereby realizing operations such as sampling and hemostasis. The driving method of the motor 42 can provide stable and precise power, ensuring that the sliding speed and displacement of the movable plate 44 are controllable, thereby ensuring the accurate and reliable action of the actuators, improving the precision and effect of the operation. At the same time, the sliding connection of the movable plate 44 can prevent it from jamming during the movement, ensuring the smoothness of the operation.

[0062] A cutting blade 411 is fixedly mounted on a movable plate 44 inside the mounting housing 41 on one side. The cutting blade 411 is slidably connected to the inner wall of the groove of the mounting housing 41. An insert block 46 is provided on the rotating cylinder 31, and a slot 45 is provided on the mounting housing 41. The slot 45 and the insert block 46 are adapted to each other. When the insert block 46 is inserted into the slot 45, the mounting housing 41 is fixed.

[0063] When sampling is required, the mounting housing 41 containing the cutting blade 411 is first rotated to the working position using the switching component 30, and positioned by the engagement of the insert 46 and the slot 45. Then, the motor 42 inside the mounting housing 41 is activated, driving the threaded rod 43 to rotate. The movable plate 44, threadedly connected to the threaded rod 43, slides linearly under the constraint of the inner wall of the mounting housing 41. The movable plate 44 drives the cutting blade 411 fixed thereon to slide synchronously. Because the cutting blade 411 is slidably connected to the inner wall of the mounting housing 41, the stability and linearity of the cutting blade 411 during the sliding process are ensured. During the sliding process, the cutting blade 411 can precisely cut the tissue of the pathological site fixed by the clamping piece 17, thereby obtaining the required pathological tissue sample. Using the cutting blade 411 for sampling can effectively avoid tissue compression and deformation, ensuring that the collected tissue sample has a complete shape and neat edges, which is beneficial for subsequent pathological examination and diagnosis, and improves the accuracy of diagnosis. Meanwhile, the motor 42 drives the cutting speed and depth of the cutting blade 411 precisely, and can adjust relevant parameters according to different tissue characteristics (such as hardness and toughness) to ensure sampling effect.

[0064] On the other side, a hemostatic electrode 412 is fixedly installed on the movable plate 44 inside the mounting housing 41, and the hemostatic electrode 412 is slidably connected to the inner wall of the mounting housing 41.

[0065] After sampling is completed, the mounting housing 41 containing the hemostatic electrode 412 is rotated to the working position by the switching component 30, and the mounting housing 41 is fixed by the cooperation of the insert 46 and the slot 45. Then, the motor 42 inside the mounting housing 41 is started. The motor 42 drives the threaded rod 43 to rotate, causing the movable plate 44, which is threadedly connected to the threaded rod 43, to slide along the inner wall of the mounting housing 41. The movable plate 44 drives the hemostatic electrode 412 to move synchronously, so that the hemostatic electrode 412 approaches and contacts the bleeding site after sampling. After the hemostatic electrode 412 is energized, a high-frequency current is generated. The thermal effect of the high-frequency current coagulates the tissue protein at the bleeding site, thereby achieving the purpose of hemostasis. Since the hemostatic electrode 412 is slidably connected to the inner wall of the mounting housing 41, the stability and accuracy of the hemostatic electrode 412 during the movement are ensured, and it can be accurately aligned with the bleeding point. The motor 42 drive can precisely control the moving distance of the hemostatic electrode 412, ensuring good contact with the bleeding site and improving the hemostasis effect. Meanwhile, this integrated hemostasis design eliminates the need to replace specialized hemostasis instruments after sampling, saving operation time and reducing the risk of excessive bleeding during instrument replacement.

[0066] A plug 46 is fixedly installed on the rotating cylinder 31. A mounting groove 47 is provided on the plug 46. A second spring 49 is fixedly installed in the mounting groove 47. A limiting protrusion 48 is fixedly installed on the other end of the second spring 49. The limiting protrusion 48 is slidably connected to the inner wall of the mounting groove 47. A slot 45 that mates with the plug 46 is provided on the mounting housing 41. A limiting hole 410 is provided in the slot 45.

[0067] When the housing 41 needs to be installed, align the slot 45 on the housing 41 with the insert 46 on the rotating cylinder 31, and then insert the insert 46 into the slot 45. During the insertion of the insert 46, the inner wall of the slot 45 will exert a squeezing force on the limiting protrusion 48, causing the limiting protrusion 48 to overcome the elastic force of the second spring 49 and retract into the mounting groove 47. When the insert 46 is fully inserted into the slot 45, the limiting protrusion 48 pops out under the elastic force of the second spring 49 and inserts into the limiting hole 410 in the slot 45, thereby fixing the mounting housing 41 on the rotating drum 31 and preventing relative movement between the mounting housing 41 and the rotating drum 31 during operation, thus ensuring the stable operation of the functional components. When it is necessary to disassemble the mounting housing 41, simply apply a certain external force to pull the mounting housing 41, causing the limiting protrusion 48 to be squeezed by the inner wall of the limiting hole 410 and retract into the mounting groove 47, so that the mounting housing 41 can be removed from the rotating drum 31. This installation and positioning method has a simple structure and is easy to operate. It can not only ensure the firmness of the connection between the mounting housing 41 and the rotating drum 31, but also facilitate the disassembly and replacement of the mounting housing 41, thereby improving the maintenance convenience and flexibility of the equipment.

[0068] like Figure 3 , Figure 4 and Figure 10 As shown, a disinfection channel 413 is provided on the rotating drum 31. An inlet pipe 414 connected to the disinfection channel 413 is fixedly installed on the rotating drum 31. An installation block 415 is fixedly installed inside the disinfection channel 413. A main shaft 416 is fixedly installed on the installation block 415. A sliding ring 417 is slidably installed on the main shaft 416. A third spring 418 is fixedly installed on the sliding ring 417. The other end of the third spring 418 is fixedly connected to the end of the main shaft 416. A rotating impeller 419 is rotatably installed on the sliding ring 417. The installation block 415 has a strip-shaped structure.

[0069] During disinfection, the disinfectant liquid is injected into the disinfection channel 413 on the rotating drum 31 through the inlet pipe 414. As the disinfectant liquid flows within the channel, it impacts the rotating impeller 419 within the channel 413, causing the impeller 419 to rotate around the sliding ring 417. The rotation of the impeller 419 agitates the disinfectant liquid, ensuring thorough and uniform mixing. The sliding ring 417 moves under the influence of the liquid and the impeller 419, connecting the outlet of the disinfection channel 413 to the outside environment. The rotating impeller 419 also causes the disinfectant liquid to spray out in a diffused manner, increasing the disinfection range and improving the disinfection effect. During operation, under the impact of the disinfectant liquid, the sliding ring 417 slides along the main shaft 416 and compresses the third spring 418. When the disinfectant liquid stops injecting, the sliding ring 417 slides back along the main shaft 416 under the elastic force of the third spring 418, driving the rotating impeller 419 to reset as well. As the disinfectant liquid flows within the disinfection channel 413, it flows out from the channel outlet, rinsing and disinfecting the pathological site and the instruments on the clamping piece 17, removing residual tissue debris and blood, and killing any bacteria and viruses that may be present, providing a clean and sterile environment for subsequent operations. The inlet pipe 414 connects to external disinfection equipment, allowing control of the injection volume and speed of the disinfectant liquid to meet different disinfection needs.

[0070] like Figure 11 and Figure 12 As shown, the limiting component includes two insertion holes 51 opened on the first clamp body 10. A mating block 54 is detachably installed in the insertion hole 51. A rotating shaft 52 is threadedly connected to the mating block 54. The rotating shaft 52 passes through the first clamp body 10 and the second clamp body 11. An abutment block 53 is fixedly installed on the rotating shaft 52.

[0071] After the first clamp 10 and the second clamp 11 are adjusted to a suitable opening angle, the mating block 54 is installed in the insertion hole 51 of the first clamp 10, fixing the mating block 54 to the first clamp 10. Since the rotating shaft 52 threadedly connected to the mating block 54 passes through the first clamp 10 and the second clamp 11, rotating the rotating shaft 52 will cause it to move axially under the action of the thread, driving the abutment block 53 fixed on the rotating shaft 52 to move synchronously. When the abutment block 53 moves to a position where it is in close contact with the second clamp 11, the rotating shaft 52 is rotated again, so that the abutment block 53 exerts a certain pressure on the second clamp 11, thereby fixing the second clamp 11 in the current position, restricting the relative rotation between the first clamp 10 and the second clamp 11, and fixing the clamp angle. This limiting method can adjust the opening and closing angle of the clamp body according to actual operation needs and reliably fix it to avoid unexpected changes in the clamp body angle during operation, thus ensuring the stability and accuracy of operation. When it is necessary to adjust the clamp body angle, rotate the rotating shaft 52 in the opposite direction to separate the abutting block 53 from the second clamp body 11, thereby adjusting the opening and closing angle of the first clamp body 10 and the second clamp body 11. After adjustment, fix it again. The mating block 54 can be detachably installed in the insertion hole 51, which facilitates the maintenance and replacement of the limiting component.

[0072] The specific workflow of the technical solution provided by this invention is as follows:

[0073] During colposcopy biopsy, the opening and closing angles of the first clamp 10 and the second clamp 11 are first adjusted according to the patient's specific condition (such as vaginal wall toughness, lesion location, etc.). During the adjustment process, the first clamp 10 and the second clamp 11 are rotated to reach a suitable angle, and then fixed using a limiting component: the mating block 54 is installed in the insertion hole 51 of the first clamp 10, and the rotating shaft 52 passing through the first clamp 10 and the second clamp 11 is rotated to drive the abutment block 53 to move and press against the second clamp 11, limiting the change of clamp angle and ensuring stable operation.

[0074] Next, the first clamp tube 12 and the second clamp tube 13 are connected and fixed by the connecting component 20: rotate the threaded sleeve 22 on the second clamp tube 13 to engage with the threaded groove 21 on the first clamp tube 12 and tighten it to ensure a firm connection between the clamp tubes and facilitate the transmission of operating force.

[0075] Then, according to the operational requirements of sampling, hemostasis and disinfection, the corresponding functional components are switched by switching component 30. Rotating cylinder 31 installed on second clamp tube 13 is rotated. During the rotation of cylinder 31, when the insertion slot 32 corresponding to the required functional component is aligned with the insertion block 35 in the movable slot 33 of second clamp tube 13, the insertion block 35 is inserted into slot 32 under the action of first spring 34, realizing the positioning of cylinder 31 and putting the functional component in the working position. If it is necessary to replace the mounting shell 41, the insertion block 46 on cylinder 31 is used to cooperate with the slot 45 of mounting shell 41, and the mounting shell 41 is quickly disassembled and assembled by limiting protrusion 48 and second spring 49.

[0076] During the sampling operation, the motor 42 inside the mounting housing 41 containing the cutting blade 411 is started. The motor 42 drives the threaded rod 43 to rotate, causing the movable plate 44, which is threaded to it, to slide along the inner wall of the mounting housing 41. The movable plate 44 drives the cutting blade 411 to extend, so as to accurately cut and sample the pathological tissue, avoid tissue compression and deformation, and ensure sample quality.

[0077] If hemostasis is required after sampling, switch to the functional component equipped with hemostatic electrode 412. Similarly, start motor 42 to drive movable plate 44 to slide, so that hemostatic electrode 412 is close to the bleeding site. Hemostatic electrode 412 is energized to achieve precise hemostasis using high-frequency current thermal effect, without the need to change instruments, saving time.

[0078] If disinfection is required during or after the operation, disinfectant liquid is injected through the inlet pipe 414 on the rotating drum 31. After entering the disinfection channel 413, the disinfectant liquid impacts the rotating impeller 419. The impeller rotates and stirs the disinfectant liquid to make it evenly mixed. At the same time, the sliding ring 417 slides along the main shaft 416 to compress the third spring 418, and the disinfectant liquid flows out from the disinfection channel 413 to rinse and disinfect the pathological site and instruments, ensuring a sterile environment and reducing the risk of infection.

[0079] Throughout the operation, the first pull rod 14 slides within the first clamp tube 12 and drives the second pull rod 15 to slide synchronously. The second pull rod 15 drives the clamping plate 17 to open and close through the pull plate 16, stably clamping the tissue around the pathological site, providing good conditions for the operation of each functional component, and realizing an integrated, efficient and precise colposcopy biopsy operation.

[0080] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
