Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a device for rapid extraction of intraoperative pathological tissue. Background Technology

[0002] In surgical procedures, intraoperative pathological diagnosis is a crucial step in determining the surgical plan, assessing the nature of the lesion (such as whether it is benign or malignant), and determining whether the resection margins are clean. It directly affects the safety of the surgery and the patient's prognosis. The rapid and accurate extraction of pathological tissue is a prerequisite for subsequent pathological analysis, and its efficiency and quality are directly related to the timeliness and accuracy of intraoperative diagnosis.

[0003] In existing technologies, pathological soft tissue is typically clamped and fixed using medical forceps, and then extracted using cutting tools and other equipment.

[0004] Existing technologies, such as the Chinese patent with publication number CN220655632U, disclose medical grasping forceps. First, the forceps head is inserted into the lesion site according to the surgical plan. Then, the forceps handle is operated to apply force to the push rod, which in turn drives the second clamping block to rotate along the connecting piece. Finally, the second clamping block switches between the clamping position and the separation position, thereby being able to grasp the pathological soft tissue at the lesion site.

[0005] Regarding the aforementioned and existing related technologies, the inventors believe that the following defects often exist: Medical grasping forceps, due to their limited functionality, can only perform clamping and lack cutting capabilities. When extracting pathological tissue during surgery, they must be frequently used in conjunction with cutting instruments such as electrocautery, ultrasonic scalpels, and surgical scissors, thereby increasing the complexity of the surgical procedure, hindering the rapid extraction of pathological tissue, prolonging the intraoperative time, and greatly increasing the risk to the patient. Furthermore, the large number of medical devices places extremely high demands on the doctor's clinical operation and experience, making it difficult to efficiently meet the core needs of accurate extraction, rapid acquisition, and safe operation of pathological tissue during surgery. Summary of the Invention

[0006] The technical problem to be solved by the present invention is that the existing technology has the disadvantage that the grasping forceps need to be bound to other medical devices for use, which makes it impossible to quickly extract pathological tissues. To this end, we propose an intraoperative rapid pathological tissue extraction device.

[0007] To achieve the above objectives, this application adopts the following technical solution: a rapid intraoperative pathological tissue extraction device, including a gripping rod, a sleeve rod fixedly installed at one end of the gripping rod, a cover head fixedly fitted at the end of the sleeve rod away from the gripping rod and connected thereto, an extraction component is provided inside the gripping rod, the sleeve rod and the cover head, a roller one and a roller two are rotatably arranged on the inner side of the gripping rod, and a through-hole plate is fixedly installed on the inner wall of the cover head;

[0008] The extraction assembly includes an extraction rod disposed inside the sleeve rod, the cover head, and the gripping rod. An adjusting component is sleeved on the outside of the extraction rod and engaged with roller one. The adjusting component is engaged with roller two. One end of the extraction rod slides through the through-hole plate and is provided with multiple sets of gripping fingers. A cutting component is provided on the outside of the extraction rod.

[0009] The cutting component includes a cylinder fixedly connected to the outer wall of the extraction rod, a sleeve movably sleeved on the outer side of the cylinder, the sleeve being rotatably connected to the through-hole plate, a cutter head fixedly installed on the outer wall of the sleeve, a ball head fixedly installed on the outer wall of the cylinder, and a threaded groove matching the ball head opened on the inner wall of the sleeve.

[0010] The adjusting component includes a half rod that is slidably connected to the extraction rod. A collar is fixedly installed on the outer wall of the half rod. The collar is located between the extraction rod and the sleeve rod. The outer walls of both the half rod and the extraction rod are provided with toothed grooves. The outer wall of roller one is provided with multiple teeth arranged in a row. The teeth mesh with the toothed grooves. Roller one and roller two have the same structure. Sealing rings are fixedly installed on the outer and inner walls of the collar. The two sealing rings are tightly fitted to the sleeve rod and the extraction rod, respectively.

[0011] Preferably, a retaining ring is fixedly installed at one end of the cover head, and the sleeve is rotatably connected to the retaining ring.

[0012] Preferably, a connecting rod is symmetrically provided at one end of the grasping finger, the connecting rod is rotatably connected to the extraction rod, and a torsion spring is fixedly sleeved on the outside of the connecting rod, with one end of the torsion spring fixedly connected to the extraction rod.

[0013] Preferably, the outer surfaces of the gripping fingers, roller one, and roller two are all provided with anti-slip grooves, and multiple sets of gripping fingers are arranged in a circle around the extraction rod as the axis, and the multiple sets of gripping fingers have the same structural composition.

[0014] Preferably, the cutter head abuts against the fixed ring, and the cutter head is a certain distance away from the inner wall of the fixed ring when it starts to rotate.

[0015] Preferably, the upper end of the grip bar is symmetrically provided with an arc-shaped outer shell, and a cover plate is slidably installed on the inner side of the arc-shaped outer shell.

[0016] Preferably, a hollow rod is fixedly installed at the other end of the gripping rod, and both the extraction rod and the half rod are slidably connected to the inner wall of the hollow rod.

[0017] Preferably, a handle is fixedly installed at the lower end of the grip rod, and the surface of the handle has a groove for placing fingers.

[0018] Technical effects of the present invention:

[0019] First, align the hood with the pathological tissue and bring it into contact. Then, use your fingers to rotate roller one, causing the adjusting element to gradually move horizontally away from the hood. Because the hood is in contact with the pathological tissue and the perforated plate is open, a negative pressure gradually forms inside, adsorbing the pathological tissue and causing some of it to gradually extend into the hood. Next, stop rotating roller one and use your fingers again to rotate roller two, causing the extraction rod to move multiple sets of grasping fingers horizontally away from the hood. This causes multiple sets of grasping fingers to simultaneously contact the perforated plate, forcing them to simultaneously... The roller rotates and moves closer to the axis of the extraction rod, gripping and pulling the pathological tissue inside the hood during horizontal movement. The extraction rod also drives the cylinder to move synchronously, forcing the sleeve to passively rotate the cutter head around its own axis. This ensures the ball head remains within the threaded groove, cutting off the gradually tightened pathological tissue. The tissue is then trapped between multiple gripping fingers. The rotation of roller two is stopped, and roller one is reversed to release the negative pressure inside the hood, allowing the pathological tissue to be analyzed to be extracted.

[0020] Advantages of this invention:

[0021] The entire process can be completed without the need for coordination with other medical equipment, effectively reducing the complexity of the surgical procedure, thus facilitating the rapid extraction of pathological tissue, reducing intraoperative time, and lowering the risk factor for patients.

[0022] The operation is simple and intuitive, allowing doctors to complete all extraction steps with one hand and minimizing interference with the surgical field of vision, making it especially suitable for surgical scenarios with limited space.

[0023] During the gripping step of the extraction process, the failure of the final extraction will not be caused by the flatness of the pathological tissue surface or the softness of the tissue during contact.

[0024] The pathological tissue to be extracted is stretched taut to ensure stable force during cutting, thereby improving cutting speed and quality.

[0025] Negative pressure adsorption targets specific areas, effectively reducing the probability of non-pathological tissues contaminating the sample and providing more accurate material for subsequent pathological analysis. Attached Figure Description

[0038] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0039] Reference Figure 1 - Figure 4 , Figure 7As shown, the present invention provides a technical solution: an intraoperative pathological tissue rapid extraction device, including a gripping rod 1, a sleeve rod 2 fixedly installed at one end of the gripping rod 1, a cover head 3 fixedly sleeved and connected at the end of the sleeve rod 2 away from the gripping rod 1, an extraction component 4 is provided inside the gripping rod 1, the sleeve rod 2 and the cover head 3, a roller 13 and a roller 2 14 are rotatably provided on the inner side of the gripping rod 1, and a through-hole plate 32 is fixedly installed on the inner wall of the cover head 3;

[0040] The extraction assembly 4 includes an extraction rod 41 disposed inside the sleeve rod 2, the cover head 3, and the gripping rod 1. An adjusting member 42 is sleeved on the outside of the extraction rod 41 and engaged with the first roller 13. The adjusting member 42 is engaged with the second roller 14. One end of the extraction rod 41 slides through the through hole plate 32 and is provided with multiple sets of gripping fingers 43. A cutting member 44 is provided on the outside of the extraction rod 41.

[0041] The cutting component 44 includes a cylinder 441 fixedly connected to the outer wall of the extraction rod 41. A sleeve 442 is movably fitted onto the outer side of the cylinder 441. The sleeve 442 is rotatably connected to the through-hole plate 32. A blade disc 443 is fixedly installed on the outer wall of the sleeve 442. A ball head 444 is fixedly installed on the outer wall of the cylinder 441. A threaded groove 445 matching the ball head 444 is opened on the inner wall of the sleeve 442. During the operation, when it is necessary to extract pathological soft tissue for pathological analysis, the hood 3 is first aligned with the pathological tissue and pressed against it. Then, the roller 13 is rotated by the fingers, so that the adjusting component 42 gradually moves horizontally away from the hood 3. As the hood 3 moves, due to the contact between it and the pathological tissue and the connection of the perforated plate 32, a negative pressure gradually forms inside, adsorbing the pathological tissue. This causes some of the pathological tissue to gradually extend into the hood 3. Then, the rotation of roller 13 stops, and the fingers are used again to rotate roller 2 14. This causes the extraction rod 41 to move horizontally away from the hood 3, resulting in multiple sets of grasping fingers 43 simultaneously contacting the perforated plate 32. This forces the multiple sets of grasping fingers 43 to rotate simultaneously and move closer to the axis of the extraction rod 41. During this horizontal movement, the extraction rod grasps and pulls the portion of the pathological tissue that has extended into the hood 3, thus lifting the tissue. During the horizontal movement of the lever 41, the cylinder 441 also moves synchronously, forcing the sleeve 442 to drive the cutter head 443 to passively rotate around its own axis. This ensures that the ball head 444 remains within the threaded groove 445, thereby cutting off the gradually tightened pathological tissue. The pathological tissue is then retained between multiple sets of grasping fingers 43. At this point, the rotation of roller 2 14 is stopped, and roller 1 13 is reversed to release the negative pressure within the cover head 3, allowing the pathological tissue to be analyzed to be extracted. The entire process can be completed without the need for coordination with other medical equipment, effectively reducing the complexity of the surgical procedure and thus facilitating... This method enables rapid extraction of pathological tissue, reducing intraoperative time and lowering patient risk. The operation is simple and intuitive, allowing doctors to complete all extraction steps with one hand, minimizing interference with the surgical field. It is particularly suitable for space-constrained surgical scenarios. During the grasping process, the method avoids extraction failure due to the smoothness of the pathological tissue surface or its softness upon contact. Furthermore, the pathological tissue to be extracted is first taut, ensuring stable force during cutting, improving cutting speed and quality. Negative pressure adsorption targets the specific area, effectively reducing the probability of non-pathological tissue contamination in the sample, providing more accurate material for subsequent pathological analysis.

[0042] Reference Figure 9 - Figure 10As shown in this embodiment: In order to ensure the effectiveness of negative pressure adsorption, a fixing ring 31 is fixedly installed at one end of the hood 3, and the sleeve 442 is rotatably connected to the fixing ring 31, which effectively expands the contact area between the hood 3 and the soft tissue, thereby closely adhering to the tissue surface and enhancing the sealing effect, ensuring stable and long-lasting negative pressure adsorption. At the same time, its rotatable connection with the sleeve 442 improves the stability during cutting without affecting the cutting action, thereby improving the extraction quality of pathological tissue.

[0043] Reference Figure 3 - Figure 5 , Figure 8 - Figure 10 As shown in this embodiment: to avoid gripping failure due to the flatness of the pathological tissue surface and its soft, agile characteristics during contact, the adjusting member 42 includes a half-rod 421 slidably connected to the extraction rod 41. A collar 423 is fixedly installed on the outer wall of the half-rod 421, located between the extraction rod 41 and the sleeve 2. Both the half-rod 421 and the extraction rod 41 have toothed grooves 422 on their outer walls. The outer wall of the roller 13 has multiple teeth 131 arranged in a row, which mesh with the toothed grooves 422. Next, roller 13 and roller 2 14 have the same structure, so when roller 13 is rotated, the meshing relationship between its teeth 131 and groove 422 will cause the half rod 421 to drive the collar 423 to move horizontally away from the hood 3. Since the hood 3 is in contact with the pathological tissue and the through-hole plate 32 is connected, a negative pressure is gradually formed inside to adsorb the pathological tissue, causing some of the pathological tissue to gradually extend into the hood 3 to wait for the subsequent grasping finger 43 to grasp it, thereby ensuring the success of the final extraction.

[0044] Reference Figure 8 - Figure 10 As shown in this embodiment: In order to ensure the effectiveness of negative pressure adsorption, sealing rings 424 are fixedly installed on both the outer and inner walls of the collar 423. The two sealing rings 424 are tightly fitted to the sleeve rod 2 and the extraction rod 41 respectively, which can effectively prevent air from flowing through the gaps under negative pressure, thereby ensuring that the negative pressure adsorption force in the hood 3 is continuously effective and preventing insufficient adsorption of pathological tissue due to air leakage, which would prevent the tissue from entering the hood 3.

[0045] Reference Figure 6As shown in this embodiment: In order to enable the device to be used repeatedly and reduce the cost of use, a connecting rod 431 is symmetrically arranged at one end of the grasping finger 43. The connecting rod 431 is rotatably connected to the extraction rod 41. A torsion spring 432 is fixedly sleeved on the outside of the connecting rod 431. One end of the torsion spring 432 is fixedly connected to the extraction rod 41. After extraction is completed, the roller 14 is reversed, so that the extraction rod 41 drives the multiple sets of grasping fingers 43 to gradually return to the initial position. Without the limitation of the through-hole plate 32, the multiple sets of grasping fingers 43 release the grip on the pathological tissue by relying on the reset potential energy of the torsion spring 432, and wait for the next extraction.

[0046] Reference Figure 5 - Figure 6 As shown in this implementation scheme: In order to improve the accuracy of the finger rotation roller and the effective grasping of pathological tissue, anti-slip grooves 434 are provided on the outer surfaces of the grasping finger 43, roller 13, and roller 2 14. Multiple sets of grasping fingers 43 are arranged in a circle around the extraction rod 41. The multiple sets of grasping fingers 43 have the same structure, which can effectively increase the friction between the finger and the roller and between the grasping finger and the pathological tissue. On the one hand, it allows the doctor to control the rotation angle of the roller more accurately, thereby precisely adjusting the negative pressure adsorption force. On the other hand, it can apply grasping force to the pathological tissue inserted into the hood head 3 from multiple directions simultaneously, avoiding tissue displacement or local excessive compression damage caused by single-point force. It is especially suitable for dealing with the soft avoidance characteristics when contacting soft tissue, ensuring a comprehensive grasping range and uniform force distribution, and reducing the risk of grasping failure.

[0047] Reference Figure 9 - Figure 10 As shown in this embodiment: In order to further improve cutting efficiency and cutting quality, the cutting disc 443 is abutted against the fixing ring 31. When the cutting disc 443 starts to rotate, it is a certain distance away from the inner wall of the fixing ring 31, so that the cutting disc 443 can cooperate with the fixing ring 31 to form a shearing force on the pathological tissue. At the same time, the pathological tissue is tightened before cutting, which can effectively improve cutting efficiency and cutting quality, thereby improving the sample quality of subsequent analysis.

[0048] Reference Figure 3 As shown in this embodiment: Since the two rollers are adjacent, they are prone to accidental contact during rotation, which affects normal use. Therefore, an arc-shaped outer shell 11 is symmetrically arranged at the upper end of the grip rod 1. A cover plate 12 is slidably installed on the inner side of the arc-shaped outer shell 11, so that when a roller needs to be rotated, the cover plate 12 on the outer side of that roller is opened, thereby effectively avoiding accidental contact with adjacent rollers.

[0049] Reference Figure 1 , Figure 3As shown in this embodiment: In order to improve the stability of the extraction rod 41 and half rod 421 during horizontal movement, a hollow rod 15 is fixedly installed at the other end of the holding rod 1. The extraction rod 41 and half rod 421 are slidably connected to the inner wall of the hollow rod 15, so that both ends are supported, thereby effectively improving the stability during movement.

[0050] Reference Figure 3 As shown in this embodiment: In order to improve the stability of the operator when operating the device, a handle 16 is fixedly installed at the lower end of the grip rod 1. The surface of the handle 16 has a groove for placing fingers, which significantly improves the stability of operation from an ergonomic point of view. The groove can naturally conform to the shape of the fingers, making the hand grip more comfortable and reducing the shaking of the device caused by unstable grip during operation. At the same time, the handle 16 provides a more stable force fulcrum for the hand. In conjunction with the operation of the grip rod 1, the doctor can apply force more precisely and controllably when driving the roller and controlling the extraction component 4. Especially in the case of long-term operation or surgical field of limited vision, it can effectively reduce hand fatigue and further ensure the stability and accuracy of extraction actions during the operation.

[0051] Working principle: During the procedure, when pathological soft tissue needs to be extracted for pathological analysis, the hood 3 is first aligned with and pressed against the pathological tissue. Then, the roller 13 is rotated using fingers, causing the adjusting element 42 to gradually move horizontally away from the hood 3. Due to the contact between the hood 3 and the pathological tissue and the connection of the through-hole plate 32, a negative pressure is gradually formed inside, adsorbing the pathological tissue and causing some of the pathological tissue 21 to gradually extend into the hood 3. Subsequently, the rotation of the roller 13 is stopped, and the roller 24 is rotated again using fingers, causing the extraction rod 41 to drive multiple sets of grasping fingers 43 to gradually move horizontally away from the hood 3, resulting in multiple sets of grasping fingers 43 simultaneously contacting the through-hole plate 32. Contact is generated, forcing multiple sets of grasping fingers 43 to rotate simultaneously and move closer to the axis of the extraction rod 41. During the horizontal movement, the extraction rod 41 grasps and pulls the pathological tissue that has entered the hood 3. The extraction rod 41 also drives the cylinder 441 to move synchronously during the horizontal movement, forcing the sleeve 442 to drive the cutter head 443 to rotate passively around its own axis, so as to ensure that the ball head 444 is always located in the threaded groove 445. This cuts off the gradually tightened pathological tissue, leaving the pathological tissue between the multiple sets of grasping fingers 43. At this time, the rotation of the second roller 14 is stopped and the first roller 13 is reversed to release the negative pressure in the hood 3, and the case tissue to be analyzed can be extracted.

[0052] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
