Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a colposcope biopsy forceps capable of simultaneous multi-point sampling. Background Technology

[0002] Colposcopy is an important diagnostic technique in gynecology, often used for screening and diagnosis of cervical cancer and precancerous lesions. During the examination, when a suspicious lesion is found, a biopsy is usually required to obtain tissue samples for pathological analysis.

[0003] Traditional colposcopic biopsy forceps are mostly single-point and single-use sampling tools, meaning that only a single tissue sample can be obtained in one operation. If multiple tissue samples need to be obtained in one operation, repeated positioning and insertion / extraction operations must be performed, which makes the operation cumbersome and time-consuming. This not only reduces the efficiency of biopsy sampling but also increases the patient's pain and bleeding risk. Furthermore, the sampling depth of the colposcopic biopsy forceps is mostly fixed, making it difficult to adjust the sampling depth more precisely for the lesion area, which affects the accuracy of sampling positioning and the accuracy of subsequent sample testing.

[0004] Furthermore, it is difficult to collect multiple samples obtained by biopsy forceps independently and quickly. If the sample collection operation is performed after the biopsy forceps are removed, the samples are prone to cross-contamination during the recovery process, which affects the reliability of subsequent pathological results. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a colposcopy biopsy forceps that can simultaneously collect multiple tissue samples from different sites in a single operation, thereby improving biopsy sampling efficiency, avoiding increased patient pain and bleeding risks, enabling more precise adjustment of tissue sampling depth, improving sampling positioning accuracy and subsequent sample testing accuracy, and allowing for independent and rapid collection of multiple samples to avoid cross-contamination and ensure the reliability of subsequent pathological results.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A colposcopy biopsy forceps capable of simultaneous multi-point sampling includes a handle sleeve, with a forceps tube fixedly connected to the end of the handle sleeve. Three adjustable biopsy forceps assemblies are fixedly connected to the inner wall of the forceps tube. A synchronous opening and closing drive assembly is fixedly connected to the inner wall of the handle sleeve. The synchronous opening and closing drive assembly is used to drive the three adjustable biopsy forceps assemblies to open and close synchronously. A protective end is fixedly connected to the end of the forceps tube. The adjustable biopsy forceps assembly includes an upper support frame and a lower support frame fixedly connected to the inner wall of the forceps tube. A sliding rod is slidably connected to the inner side of the upper support frame and the lower support frame. A telescopic bracket is fixedly connected to the bottom end of the sliding rod, and a movable clamp is fixedly connected to the telescopic end of the telescopic bracket. The circumferential sidewall of the forceps tube is fixedly connected to an adapter tube. The end of the adapter tube located outside the forceps tube is fixedly connected to a telescopic tube. The end of the telescopic tube is fixedly connected to an abutment frame. The outer wall of the abutment frame is fixedly connected to two limiting side rails. The end of the movable clamp contacts and slides in contact with the two limiting side rails. The movable clamp slides against the outer wall of the abutment frame. The outer wall of the abutment frame is fixedly connected to a fixed clamp. The movable clamp can be moved close to the fixed clamp to obtain tissue samples.

[0008] Optionally, the synchronous opening and closing drive assembly includes a support circular plate fixedly connected to the inner wall of the handle sleeve, a small motor fixedly installed on the outer wall of the support circular plate, and an opening and closing button fixedly installed on the outer peripheral wall of the handle sleeve, the opening and closing button being used to control the small motor to open and close. The output end of the small motor passes through the supporting circular plate and is fixedly connected to an annular corrugated plate. The top ends of the three slide rods are fixedly connected to abutting rollers. The three abutting rollers are in contact with the annular corrugated plate and roll in cooperation. The outer peripheral walls of the three slide rods are fitted with tension springs, and the outer peripheral walls of the three slide rods are fixedly connected to sliding plates. The two ends of the tension springs are fixedly connected to the upper support frame and the sliding plates, respectively.

[0009] Optionally, the rapid sample collection assembly includes an L-shaped connecting tube fixedly connected to the bottom end of the sealed collection frame, a concave collection tube fixedly connected to the inner wall of the adapter tube, the concave collection tube being fixedly connected to the L-shaped connecting tube, a piston plate being slidably connected to the inner wall of the sealed cavity, a transmission rod being fixedly connected to the outer peripheral wall of the output end of the small motor, the transmission rod being fixedly connected to the piston plate, and multiple pressure relief holes being provided at the bottom end of the sealed collection frame.

[0010] Optionally, the rapid sample collection assembly further includes a second electromagnet ring fixedly connected to the end of the lower support frame, a second magnetic ring fixedly connected to the slider, and a second control knob fixedly installed on the outer peripheral wall of the handle sleeve. The second control knob is used to control the current of the second electromagnet ring. When energized, the second electromagnet ring and the second magnetic ring are attracted to each other by opposite poles. The second electromagnet ring, the second control knob, the first electromagnet ring, the first control knob, the small motor, and the on / off button are all electrically connected to an external power source.

[0011] Optionally, the top of the sealed collection frame is provided with an arc-shaped sliding hole, and the transmission rod slides with the sealed collection frame through the arc-shaped sliding hole. An arc-shaped sealing pressure plate is fixedly connected to the transmission rod, and the arc-shaped sealing pressure plate slides with the upper end surface of the sealed collection frame.

[0012] Optionally, the circumferential sidewall of the clamp tube has a movable hole at the telescopic bracket. The telescopic bracket slides with the circumferential sidewall of the clamp tube through the movable hole.

[0013] Optionally, the side wall of the sealed collection frame is provided with a sampling port, and a magnetic sealing plate is movably installed at the sampling port of the sealed collection frame.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) In this invention, the telescopic support drives the three movable clamps to move toward the corresponding fixed clamps, so as to realize the synchronous closure of the jaws of the three sets of movable clamps and fixed clamps. Thus, multiple tissue samples can be obtained from different parts at the same time in a single operation, improving the efficiency of biopsy sampling and avoiding increasing the patient's pain and bleeding risk. The fixed clamps and movable clamps can be moved and adjusted to a predetermined depth to achieve more precise tissue sampling depth adjustment, improve the accuracy of sampling positioning and subsequent sample detection. Furthermore, multiple samples can be collected independently and quickly, avoiding cross-contamination of multiple samples and ensuring the reliability of subsequent pathological results. (2) In this invention, the adjustable biopsy forceps assembly uses a small motor to drive the annular corrugated plate to rotate slowly. The three abutting rollers contact the annular corrugated plate under the tension of the tension spring. When the annular corrugated plate rotates, multiple crests simultaneously lift the three abutting rollers, thereby pushing the three sets of sliding rods and telescopic brackets to move synchronously closer to the protective end. The telescopic brackets drive the three movable clamps to move towards the corresponding fixed clamps, so as to realize the synchronous closing of the jaws of the three sets of movable clamps and the fixed clamps. Thus, multiple tissue samples can be obtained from different parts at the same time in a single operation, improving the biopsy sampling efficiency and avoiding increasing the patient's pain and bleeding risk. (3) In this invention, if it is necessary to make precise adjustment of the sampling depth separately, the current of the first electromagnet ring in the corresponding adjustable biopsy forceps assembly can be adjusted by rotating the first control knob of the synchronous opening and closing drive assembly to change the magnetic repulsion between the first electromagnet ring and the first magnetic ring. Under the tension of the micro tension spring, the limiting shaft can slide freely relative to the limiting ring and the slide groove, so as to push the abutting frame, the fixed clamp and the movable clamp to move away from or closer to the clamp tube. Thus, the fixed clamp and the movable clamp can be moved and adjusted to the predetermined depth, so as to achieve more precise tissue sampling depth adjustment, improve the sampling positioning accuracy and subsequent sample detection accuracy. (4) In this invention, the current of the second electromagnet ring is increased by rotating the second control knob of the sample rapid collection component, so as to increase the magnetic attraction between the second electromagnet ring and the second magnetic ring, so that the position of the slide bar is fixed relative to the clamp tube and the small gap between the fixed clamp and the movable clamp is maintained. Then, the small motor is controlled to continue to run. The small motor drives multiple transmission rods on its output end to rotate, so that multiple piston plates are driven to slide in the corresponding sealed cavities through the transmission rods, so as to generate a negative pressure environment in the sealed cavity. The negative pressure is transmitted through the L-shaped connecting tube and the concave collection tube and forms a negative pressure suction force. The negative pressure suction force acts on the tissue sample being clamped through the small gap between the fixed clamp and the movable clamp, so that the tissue sample is quickly and completely sucked into the concave collection tube and transported to the sealed cavity for storage through the L-shaped connecting tube. Thus, multiple samples can be collected independently and quickly, avoiding cross-contamination of multiple samples and ensuring the reliability of subsequent pathological results.

Detailed Implementation

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention and therefore only show the components relevant to the present invention.

[0017] like Figures 1-9As shown, a colposcopy biopsy forceps capable of simultaneous multi-point sampling includes a handle sleeve 1, with a forceps tube 2 fixedly connected to the end of the handle sleeve 1. Three adjustable biopsy forceps assemblies 3 are fixedly connected to the inner wall of the forceps tube 2. A synchronous opening and closing drive assembly 4 is fixedly connected to the inner wall of the handle sleeve 1, used to drive the three adjustable biopsy forceps assemblies 3 to open and close synchronously. A protective end 5 is fixedly connected to the end of the forceps tube 2. Each adjustable biopsy forceps assembly 3 includes an upper support frame 31 and a lower support frame 32 fixedly connected to the inner wall of the forceps tube 2. A sliding rod 33 is slidably connected to the inner sides of the upper support frame 31 and the lower support frame 32. A telescopic bracket 34 is fixedly connected to the bottom end of the sliding rod 33, and a movable clamp 35 is fixedly connected to the telescopic end of the telescopic bracket 34. A circumferential sidewall of the forceps tube 2 is fixedly connected to... The adapter tube 36 has a telescopic tube 37 fixedly connected to its end outside the clamp tube 2. The end of the telescopic tube 37 is fixedly connected to an abutment frame 38. Two limiting side rails 39 are fixedly connected to the outer wall of the abutment frame 38. The end of the movable clamp 35 contacts and slides with the two limiting side rails 39. The movable clamp 35 slides against the outer wall of the abutment frame 38. A fixed clamp 317 is fixedly connected to the outer wall of the abutment frame 38. The movable clamp 35 can be moved close to the fixed clamp 317 to obtain tissue samples. A sealed collection frame 6 is fixedly connected to the outer wall of the clamp tube 2 near the handle sleeve 1. The sealed collection frame 6 has three sealed cavities 7 inside. Three sample rapid collection components 8 are fixedly connected to the bottom of the sealed collection frame 6 at the position of the three sealed cavities 7.

[0018] The telescopic support 34 drives three movable clamps 35 to move towards their corresponding fixed clamps 317, achieving synchronous closure of the jaws of the three movable clamps 35 and the fixed clamps 317. This allows for the simultaneous acquisition of multiple tissue samples from different sites in a single operation, improving biopsy efficiency and avoiding increased patient pain and bleeding risks. Individually moving and adjusting the fixed clamps 317 and movable clamps 35 to a predetermined depth enables more precise adjustment of tissue sampling depth, improving sampling positioning accuracy and subsequent sample testing accuracy. Furthermore, the rapid sample collection component 8 allows for the independent and rapid collection of multiple samples, preventing cross-contamination and ensuring the reliability of subsequent pathological results.

[0019] The telescopic support 34 adopts a multi-level nested elastic telescopic structure with a telescopic stroke of 5-15mm. It is integrally molded from medical-grade stainless steel. The telescopic end of the telescopic support 34 is fixed to the movable clamp 35 by laser welding to ensure transmission stability. The telescopic support 34 has a built-in micro damper to limit the telescopic speed to no more than 2mm / s to avoid tissue damage.

[0020] The adjustable biopsy forceps assembly 3 also includes two limiting rings 310 fixedly connected to the axial outer wall of the adapter tube 36. Two sliding grooves 311 are opened on the axial outer wall of the adapter tube 36 at the two limiting rings 310. Two limiting shafts 312 are fixedly connected to the outer wall of the abutment frame 38. The two limiting shafts 312 slide relative to the two limiting rings 310 and the two sliding grooves 311 respectively. Multiple miniature tension springs 313 are fixedly connected between the adapter tube 36 and the abutment frame 38. A first electromagnet ring 314 is fixedly connected to the end of each of the two limiting rings 310 near the abutment frame 38. A first magnetic ring 315 is fixedly connected to the outer wall of each of the two limiting shafts 312. A first control knob 316 is fixedly installed on the outer peripheral wall of the handle sleeve 1. The first control knob 316 is used to control the current of the first electromagnet ring 314. When the first electromagnet ring 314 is energized, the first electromagnet ring 314 and the first magnetic ring 315 are like poles and repel each other.

[0021] Specifically, by rotating the first control knob 316, the current of the first electromagnet ring 314 in the corresponding adjustable biopsy forceps assembly 3 is adjusted, thereby changing the magnetic repulsion between the first electromagnet ring 314 and the first magnetic ring 315. Under the tension of the miniature tension spring 313, the limiting shaft 312 slides freely relative to the limiting ring 310 and the slide groove 311, thereby pushing the abutment frame 38, the fixed clamp 317 and the movable clamp 35 to move away from or closer to the clamp tube 2. This allows the fixed clamp 317 and the movable clamp 35 to be moved and adjusted to a predetermined depth, achieving more precise tissue sampling depth adjustment, improving the accuracy of sampling positioning and subsequent sample detection.

[0022] The synchronous opening and closing drive assembly 4 includes a support circular plate 41 fixedly connected to the inner wall of the handle sleeve 1. A small motor 42 is fixedly installed on the outer wall of the support circular plate 41. An opening and closing button 43 is fixedly installed on the outer peripheral wall of the handle sleeve 1. The opening and closing button 43 is used to control the opening and closing of the small motor 42. The output end of the small motor 42 passes through the support circular plate 41 and is fixedly connected to an annular corrugated plate 44. The top ends of the three slide rods 33 are all fixedly connected to abutting rollers 45. The three abutting rollers 45 are all in contact with the annular corrugated plate 44 and roll in cooperation. The outer peripheral walls of the three slide rods 33 are all fitted with tension springs 46, and the outer peripheral walls of the three slide rods 33 are all fixedly connected to sliding plates 47. The two ends of the tension springs 46 are fixedly connected to the upper support frame 31 and the sliding plates 47, respectively.

[0023] Specifically, a small motor 42 drives the annular corrugated plate 44 to rotate slowly. Three abutting rollers 45 contact the annular corrugated plate 44 under the tension of the tension spring 46. When the annular corrugated plate 44 rotates, multiple crests of the annular corrugated plate 44 simultaneously lift the three abutting rollers 45, thereby pushing the three sets of sliding rods 33 and telescopic brackets 34 to move synchronously closer to the protective end 5. The telescopic brackets 34 drive the three movable clamps 35 to move closer to the corresponding fixed clamps 317, so that the jaws of the three sets of movable clamps 35 and the fixed clamps 317 close synchronously. Thus, multiple tissue samples can be obtained from different parts at the same time in a single operation, improving the efficiency of biopsy sampling and avoiding increasing the patient's pain and bleeding risk.

[0024] If precise adjustment of the sampling depth is required, the current of the first electromagnet ring 314 in the corresponding adjustable biopsy forceps assembly 3 can be adjusted by rotating the first control knob 316. This changes the magnetic repulsion between the first electromagnet ring 314 and the first magnetic ring 315. Under the tension of the miniature tension spring 313, the limiting shaft 312 slides freely relative to the limiting ring 310 and the slide groove 311. This pushes the abutment frame 38, the fixed clamp 317, and the movable clamp 35 to move away from or closer to the clamp tube 2. This allows the fixed clamp 317 and the movable clamp 35 to be moved and adjusted to the predetermined depth, achieving more precise tissue sampling depth adjustment and improving the accuracy of sampling positioning and subsequent sample detection.

[0025] The rapid sample collection assembly 8 includes an L-shaped connecting pipe 81 fixedly connected to the bottom of the sealed collection frame 6, a concave collection pipe 82 fixedly connected to the inner wall of the adapter pipe 36, the concave collection pipe 82 and the L-shaped connecting pipe 81 being fixedly connected, a piston plate 83 being slidably connected to the inner wall of the sealed cavity 7, a transmission rod 84 being fixedly connected to the outer peripheral wall of the output end of the small motor 42, the transmission rod 84 being fixedly connected to the piston plate 83, and multiple pressure relief holes 85 being opened at the bottom of the sealed collection frame 6. The sample rapid collection component 8 also includes a second electromagnet ring 86 fixedly connected to the end of the lower support frame 32, a second magnetic ring 87 fixedly connected to the slider 47, and a second control knob 88 fixedly installed on the outer peripheral wall of the handle sleeve 1. The second control knob 88 is used to control the current of the second electromagnet ring 86. When the second electromagnet ring 86 is energized, it attracts the second magnetic ring 87 with opposite poles. The second electromagnet ring 86, the second control knob 88, the first electromagnet ring 314, the first control knob 316, the small motor 42, and the on / off button 43 are all electrically connected to an external power supply.

[0026] Specifically, by rotating and adjusting the second control knob 88, the current of the second electromagnet ring 86 is increased, thereby increasing the magnetic attraction between the second electromagnet ring 86 and the second magnetic ring 87. This fixes the position of the slide rod 33 relative to the clamp tube 2 and maintains a small gap between the fixed clamp 317 and the movable clamp 35. This, in turn, controls the small motor 42 to continue operating. The small motor 42 drives multiple transmission rods 84 on its output end to rotate, thereby driving multiple piston plates 83 to slide and seal within their respective sealing cavities 7. This creates a negative pressure environment within the sealed cavity 7. The negative pressure is transmitted through the L-shaped connecting tube 81 and the concave collection tube 82, forming a negative pressure suction. The negative pressure suction acts on the tissue sample being clamped through the tiny gap between the fixed clamp 317 and the movable clamp 35, so that the tissue sample can be quickly and completely drawn into the concave collection tube 82 and transported to the sealed cavity 7 for storage via the L-shaped connecting tube 81. This allows for the independent and rapid collection of multiple samples, avoiding cross-contamination between multiple samples and ensuring the reliability of subsequent pathological results.

[0027] The top of the sealed collection frame 6 is provided with an arc-shaped sliding hole 9. The transmission rod 84 slides and engages with the sealed collection frame 6 through the arc-shaped sliding hole 9. That is, an arc-shaped sealing pressure plate 10 is fixedly connected to the transmission rod 84, and the arc-shaped sealing pressure plate 10 slides and engages with the upper end surface of the sealed collection frame 6. The transmission rod 84, the arc-shaped sealing pressure plate 10 and the piston plate 83 move synchronously, thereby ensuring the airtightness of the sealing cavity 7, so that a negative pressure can be smoothly formed inside it to complete the sample collection.

[0028] The circumferential sidewall of the forceps tube 2 has a movable hole 11 located at the telescopic bracket 34. The telescopic bracket 34 slides with the circumferential sidewall of the forceps tube 2 through the movable hole 11. Two protective folding plates 12 are fixedly connected to the inner wall of the movable hole 11, and both protective folding plates 12 are fixedly connected to the telescopic bracket 34. The protective folding plates 12 are made of medical-grade silicone, with a thickness of 1.5mm, and have a folded structure. When unfolded, they completely cover the movable hole 11. They are fixed to the inner wall of the movable hole 11 and the telescopic bracket 34 respectively with food-grade adhesive to prevent tissue fluid from seeping into the interior of the forceps tube 2, while not affecting the telescopic movement of the bracket.

[0029] A sampling port 13 is provided on the side wall of the sealed collection frame 6. A magnetic sealing plate 14 is movably installed at the sampling port 13 in the sealed collection frame 6. The magnetic sealing plate 14 is embedded in the sampling port 13. The sampling port 13 can be opened by pulling out the magnetic sealing plate 14 so that the sample can be taken out from the sampling port 13. Conversely, the magnetic sealing plate 14 is embedded in the sampling port 13 to ensure the sealing of the sealed cavity 7.

[0030] Working principle: Based on the lesion observed by the colposcope, press the start / stop button 43 to control the operation of the small motor 42. The small motor 42 drives the annular corrugated plate 44 to rotate slowly. The three abutting rollers 45 contact the annular corrugated plate 44 under the tension of the tension spring 46. When the annular corrugated plate 44 rotates, multiple crests of the annular corrugated plate 44 simultaneously lift the three abutting rollers 45, thereby pushing the three sets of sliding rods 33 and telescopic brackets 34 to move synchronously closer to the protective end 5. The telescopic brackets 34 drive the three movable clamps 35 to move closer to the corresponding fixed clamps 317, so as to realize the synchronous closing of the jaws of the three sets of movable clamps 35 and the fixed clamps 317, so that multiple tissue samples can be obtained from different parts simultaneously in a single operation. During the simultaneous acquisition of multiple samples from the lesion area, if it is necessary to make precise adjustments to the sampling depth individually, the current of the first electromagnet ring 314 in the corresponding adjustable biopsy forceps assembly 3 can be adjusted by rotating the first control knob 316. This changes the magnetic repulsion between the first electromagnet ring 314 and the first magnetic ring 315. Under the tension of the miniature tension spring 313, the limiting shaft 312 slides freely relative to the limiting ring 310 and the slide groove 311, thereby pushing the abutment frame 38, the fixed clamp 317 and the movable clamp 35 to move away from or closer to the clamp tube 2. This allows the fixed clamp 317 and the movable clamp 35 to be moved and adjusted to the predetermined depth, achieving more precise adjustment of the tissue sampling depth. After the tissue sample is clamped, the current of the second electromagnet ring 86 is increased by rotating the second control knob 88, thereby increasing the magnetic attraction between the second electromagnet ring 86 and the second magnetic ring 87. This overcomes the tension of the tension spring 46, fixing the position of the slide rod 33 relative to the clamp tube 2 and maintaining a small gap between the fixed clamp 317 and the movable clamp 35. This controls the small motor 42 to continue running, driving multiple transmission rods 84 on its output end to rotate. The transmission rods 84 drive multiple piston plates 83 to slide and seal in their respective sealed cavities 7, creating a negative pressure environment within the sealed cavity 7. The negative pressure is transmitted through the L-shaped connecting tube 81 and the concave collecting tube 82, forming a negative pressure suction force. This negative pressure suction force acts on the clamped tissue sample through the small gap between the fixed clamp 317 and the movable clamp 35, so that the tissue sample is quickly and completely sucked into the concave collecting tube 82 and transported to the sealed cavity 7 for storage via the L-shaped connecting tube 81.

[0031] In summary, this invention proposes a colposcopy biopsy forceps capable of simultaneous multi-point sampling. In a single operation, multiple tissue samples can be obtained from different sites simultaneously, improving biopsy sampling efficiency, avoiding increased patient pain and bleeding risks, while also enabling more precise adjustment of tissue sampling depth, improving sampling positioning accuracy and subsequent sample testing accuracy. Furthermore, it allows for independent and rapid collection of multiple samples, avoiding cross-contamination and ensuring the reliability of subsequent pathological results.
