Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and in particular to a device for rapidly extracting pathological tissue during surgery. Background Art

[0002] In surgical operations, intraoperative pathological diagnosis is a key step in determining the surgical plan and judging the nature of the lesion, such as whether it is benign or malignant, and whether the resection margin is clean. It directly affects the safety of the operation and the patient's prognosis. Among them, the rapid and accurate extraction of pathological tissue is the prerequisite for subsequent pathological analysis, and its efficiency and quality are directly related to the timeliness and accuracy of intraoperative diagnosis.

[0003] In the prior art, pathological soft tissue is generally clamped and fixed by medical forceps, and then used with cutting tools and other equipment to achieve the extraction of pathological tissue.

[0004] For example, the existing technology, such as the Chinese patent with the existing announcement number CN220655632U, discloses a medical grasping forceps. First, the forceps head of the medical grasping forceps is extended into the lesion site according to the surgical planned path, and then the forceps handle is operated to apply force to the push rod, which can drive the second clamping block to rotate along the connecting piece, and finally the second clamping block is switched between the clamping position and the separation position, so that the pathological soft tissue at the lesion site can be clamped.

[0005] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: medical forceps have a single function and can only achieve clamping, but lack cutting ability. When extracting pathological tissue during surgery, they must be frequently coordinated with cutting instruments such as electric knives, ultrasonic knives, and surgical scissors, thereby increasing the complexity of the surgical process, which is not conducive to the rapid extraction of pathological tissue, resulting in prolonged intraoperative time and greatly increasing the patient's risk factor. In addition, the large number of medical equipment also places extremely high demands on the doctor's clinical operation and experience, making it difficult to efficiently adapt to 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 equipment for use, resulting in the inability to quickly extract pathological tissue. For this reason, we propose a device for rapid extraction of pathological tissue during surgery.

[0007] To achieve the above-mentioned purpose, the present application adopts the following technical solution: a device for rapid extraction of pathological tissue during surgery, comprising a gripping rod, a sleeve rod fixedly mounted on one end of the gripping rod, a cover head fixedly mounted on an end of the cover rod away from the gripping rod and in communication with each other, an extraction assembly being arranged inside the gripping rod, a first roller and a second roller being rotatably mounted on the inner side of the gripping rod, and a through-hole disk being fixedly mounted on the inner wall of the cover head; The extraction assembly includes an extraction rod arranged on the inner side of the sleeve rod, the cover head and the gripping rod, an adjustment member is sleeved on the outer side of the extraction rod and is engaged with the first roller, the extraction rod is engaged with the second roller, one end of the extraction rod slides through the through-hole disk and is provided with multiple groups of gripping fingers, and a cutting member is provided on the outer side of the extraction rod; The cutting part includes a cylinder fixedly connected to the outer wall of the extraction rod, a sleeve is movably sleeved on the outer side of the cylinder, the sleeve is rotatably connected to the through-hole disk, a cutter disc is fixedly installed on the outer wall of the sleeve, a ball head is fixedly installed on the outer wall of the cylinder, and a threaded groove matching the ball head is opened on the inner wall of the sleeve.

[0008] Preferably, a fixing ring is fixedly mounted on one end of the cover head, and the sleeve is rotatably connected to the fixing ring.

[0009] Preferably, the adjusting member includes a half rod slidably connected to the extraction rod, a collar is fixedly mounted on the outer wall of the half rod, the collar is located between the extraction rod and the collar, the outer walls of the half rod and the extraction rod are both provided with grooves, the outer wall of roller one is arranged with a plurality of teeth, the teeth are meshed with the grooves, and the structural composition of roller one and roller two is the same.

[0010] Preferably, sealing rings are fixedly mounted on the outer wall and the inner wall of the collar, and the two sealing rings are tightly fitted with the sleeve rod and the extraction rod respectively.

[0011] Preferably, a connecting rod is symmetrically provided at one end of the grabbing finger, the connecting rod is rotatably connected to the extraction rod, and a torsion spring is provided on the outer fixed sleeve of the connecting rod, one end of the torsion spring is fixedly connected to the extraction rod.

[0012] Preferably, the outer surfaces of the grabbing fingers, roller one and roller two are all provided with anti-slip grooves, and the multiple groups of grabbing fingers are arranged in a circle with the extraction rod as the axis, and the structural composition of the multiple groups of grabbing fingers is the same.

[0013] Preferably, the cutter disc abuts against the fixing ring, and when the cutter disc starts to rotate, it is a distance away from the inner wall of the fixing ring.

[0014] Preferably, an arc-shaped outer shell is symmetrically provided on the upper end of the gripping rod, and a cover plate is slidably mounted on the inner side of the arc-shaped outer shell.

[0015] Preferably, a cavity rod is fixedly mounted on the other end of the gripping rod, and the extraction rod and the half rod are both slidably connected to the inner wall of the cavity rod.

[0016] Preferably, a handle is fixedly mounted on the lower end of the gripping rod, and a groove for placing fingers is provided on the surface of the handle.

[0017] Technical effects of the present invention: First, align the cover head with the pathological tissue and make it contact with it. Then, use your fingers to rotate the roller, so that the adjusting part gradually moves horizontally away from the cover head. Due to the contact between the cover head and the pathological tissue and the communication between the through-hole disk, negative pressure is gradually formed inside the cover head, which adsorbs the pathological tissue, causing part of the pathological tissue to gradually extend into the cover head.

[0018] Stop rotating roller one and use your fingers to rotate roller two again, so that the extraction rod drives multiple groups of grabbing fingers to gradually move horizontally away from the cover head, causing multiple groups of grabbing fingers to come into contact with the through-hole disk at the same time, forcing multiple groups of grabbing fingers to rotate at the same time and approach the axis of the extraction rod, and then grasp and pull part of the pathological tissue extending into the cover head during the horizontal movement.

[0019] During the horizontal movement, the extraction rod will also drive the cylinder to move synchronously, forcing the sleeve to drive the cutter disc to passively rotate around its own axis to ensure that the ball head is always located in the thread groove, thereby cutting off the gradually tightened pathological tissue and causing the pathological tissue to remain between multiple groups of grasping fingers.

[0020] Stop rotating the second roller and reverse the first roller to release the negative pressure in the cover head, and the pathological tissue to be analyzed can be extracted.

[0021] Advantages of the present invention: The extraction of pathological tissue can be completed without the need for coordination with other medical equipment throughout the entire process, effectively reducing the complexity of the surgical process, thereby facilitating the rapid extraction of pathological tissue, reducing intraoperative time and lowering the patient's risk factor.

[0022] The operation is simple and intuitive. The doctor can complete all extraction steps with one hand and minimize interference with the surgical field of view. It is especially suitable for surgical scenarios with limited space.

[0023] During the grasping step of the extraction process, the final extraction will not fail due to the flat surface of the pathological tissue and the soft avoidance during contact.

[0024] The pathological tissue to be extracted is tightened to stabilize the force during cutting, thereby improving the cutting speed and cutting quality.

[0025] Negative pressure adsorption targets the target area and can effectively reduce the probability of non-pathological tissue being mixed into the sample, providing more accurate materials for subsequent pathological analysis. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of the present invention and should not be regarded as the entire invention or as a limitation or restriction of the technical solution of the present invention.

[0029] Reference Figure 1 - Figure 4 、 Figure 7As shown, the present invention provides a technical solution: a device for rapid extraction of pathological tissue during surgery, comprising a gripping rod 1, a sleeve rod 2 fixedly mounted on one end of the gripping rod 1, a cover head 3 fixedly mounted on the end of the cover rod 2 away from the gripping rod 1 and connected to each other, an extraction assembly 4 is disposed inside the gripping rod 1, a roller 13 and a roller 2 14 are rotatably disposed on the inner side of the gripping rod 1, and a through-hole disk 32 is fixedly mounted on the inner wall of the cover head 3; The extraction assembly 4 includes an extraction rod 41 disposed inside the sleeve rod 2, the cover head 3, and the gripping rod 1. The outer side of the extraction rod 41 is provided with an adjustment member 42 that is engaged with the roller 13. The extraction rod 41 is engaged with the roller 2 14. One end of the extraction rod 41 slides through the through-hole plate 32 and is provided with multiple groups of gripping fingers 43. The outer side of the extraction rod 41 is provided with a cutting member 44. The cutting piece 44 includes a cylinder 441 fixedly connected to the outer wall of the extraction rod 41, a sleeve 442 is movably sleeved on the outer side of the cylinder 441, the sleeve 442 is rotatably connected to the through-hole disk 32, a knife 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, and a threaded groove 445 matching the ball head 444 is provided on the inner wall of the sleeve 442. During the operation, when it is necessary to extract pathological soft tissue for pathological analysis, the cover head 3 is first aligned with the pathological tissue and abutted, and then the finger is used to rotate the roller 13 so that the adjustment piece 42 gradually moves horizontally away from the cover head 3. The shroud 3 is moved so that the shroud 3 abuts against the pathological tissue and the through-hole disk 32 is connected, and a negative pressure is gradually formed inside the shroud 3 to adsorb the pathological tissue, causing part of the pathological tissue to gradually extend into the shroud 3. Then, the rotation of the roller 13 is stopped and the roller 2 14 is rotated again with the fingers, so that the extraction rod 41 drives the multiple groups of grasping fingers 43 to gradually move horizontally away from the shroud 3, causing the multiple groups of grasping fingers 43 to come into contact with the through-hole disk 32 at the same time, forcing the multiple groups of grasping fingers 43 to rotate at the same time and approach the axis of the extraction rod 41, and then in the process of horizontal movement, the part of the pathological tissue extending into the shroud 3 is grasped and pulled, and the extraction rod 41 is lifted. The rod 41 will also drive 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 to ensure that the ball head 444 is always located in the threaded groove 445, thereby cutting off the gradually tightened pathological tissue and causing the pathological tissue to be retained between the multiple groups of grasping fingers 43. At this time, the rotation of the roller 2 14 is stopped and the roller 1 13 is reversed to release the negative pressure state in the cover head 3, so that the pathological tissue to be analyzed can be extracted. The extraction of the pathological tissue can be completed without the need to cooperate with other medical equipment throughout the process, effectively reducing the complexity of the surgical process, and thus facilitating the extraction of the pathological tissue. It is used for the rapid extraction of pathological tissue, reducing intraoperative time and lowering the risk factor for patients. The operation is simple and intuitive. The doctor can complete all extraction steps with one hand, and it does not interfere with the surgical field of view. It is especially suitable for surgical scenarios with limited space. In the grasping step of the extraction process, the final extraction will not fail due to the flat surface of the pathological tissue and the soft avoidance during contact. The pathological tissue to be extracted is first tightened to stabilize the force during cutting, thereby improving the cutting speed and cutting quality. The negative pressure adsorption targets the target area, which can effectively reduce the probability of non-pathological tissue being mixed in the sample, providing more accurate materials for subsequent pathological analysis.

[0030] 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 cover head 3, and the sleeve 442 is rotatably connected to the fixing ring 31, which effectively expands the contact area between the cover head 3 and the soft tissue, and then closely fits the tissue surface to enhance the sealing effect, ensuring that the negative pressure adsorption is stable and long-lasting. 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.

[0031] Reference Figure 3 - Figure 5 、 Figure 8 - Figure 10 As shown, in this embodiment: in order to avoid the failure of grasping due to the flat surface of the pathological tissue and the soft avoidance characteristics during contact, the adjusting member 42 includes a half rod 421 slidably connected to the extraction rod 41, and the outer wall of the half rod 421 is fixedly installed with a ring 423. The ring 423 is located between the extraction rod 41 and the sleeve rod 2. The outer walls of the half rod 421 and the extraction rod 41 are both provided with a tooth groove 422. The outer wall of the roller 13 is arranged with a plurality of teeth 131, and the teeth 131 are engaged with the tooth groove 422. Then, the structures of roller 13 and roller 2 14 are the same, so when roller 13 is rotated, the meshing relationship between its teeth 131 and the tooth grooves 422 will prompt the half rod 421 to drive the ring 423 to move horizontally away from the cover head 3. Since the cover head 3 abuts against the pathological tissue and the through-hole disk 32 is connected, negative pressure is gradually formed inside the cover head 3 to adsorb the pathological tissue, causing part of the pathological tissue to gradually extend into the cover head 3 and wait for the subsequent grasping fingers 43 to grasp it, thereby ensuring the success of the final extraction.

[0032] Reference Figure 8 - Figure 10 As shown, in this embodiment: in order to ensure that the negative pressure adsorption must be effective, a sealing ring 424 is fixedly installed on the outer wall and the inner wall of the ring 423. The two sealing rings 424 are tightly fitted with the sleeve rod 2 and the extraction rod 41 respectively, which can effectively prevent air from flowing through the gap under the negative pressure state, thereby ensuring that the negative pressure adsorption force in the cover head 3 is continuously effective, and preventing the pathological tissue from being insufficiently adsorbed due to leakage and unable to enter the cover head 3.

[0033] Reference Figure 6As shown, in this embodiment: in order to make the device reusable and reduce the cost of use, a connecting rod 431 is symmetrically provided at one end of the grasping finger 43, and the connecting rod 431 is rotatably connected to the extraction rod 41. The outer fixed sleeve of the connecting rod 431 is provided with a torsion spring 432, and one end of the torsion spring 432 is fixedly connected to the extraction rod 41. When the extraction is completed, the roller 2 14 is reversed so that the extraction rod 41 drives the multiple groups of grasping fingers 43 to gradually return to the initial position. In the absence of the through-hole disk 32, the multiple groups of grasping fingers 43 rely on the reset potential energy of the torsion spring 432 to release the grip on the pathological tissue and wait for the next extraction.

[0034] Reference Figure 5 - Figure 6 As shown, in this embodiment: in order to improve the accuracy of finger rotation of the roller and the effective grasping of pathological tissue, anti-slip grooves 434 are provided on the outer surfaces of the grasping fingers 43 and roller one 13 and roller two 14, and multiple groups of grasping fingers 43 are arranged in a circle with the extraction rod 41 as the axis. The multiple groups of grasping fingers 43 have the same structural composition, which can effectively increase the friction between the fingers and the rollers and between the grasping fingers and the pathological tissue. On the one hand, it can enable the doctor to more accurately control the roller rotation angle, and then accurately adjust the negative pressure adsorption force, and can simultaneously apply grasping force to the pathological tissue extending into the hood head 3 from multiple directions, avoiding tissue displacement or local excessive extrusion damage due to single-point force, which is particularly suitable for dealing with the soft avoidance characteristics during soft tissue contact, ensuring a comprehensive grasping range and uniform degree distribution, and reducing the risk of grasping failure.

[0035] Reference Figure 9 - Figure 10 As shown, in this embodiment: in order to further improve the cutting efficiency and cutting quality, the blade disc 443 is abutted against the fixed ring 31, and the blade disc 443 starts to rotate at a distance from the inner wall of the fixed ring 31, so that the blade disc 443 can cooperate with the fixed ring 31 to form a shear force on the pathological tissue. At the same time, the pathological tissue is cut after being tightened, which can effectively improve the cutting efficiency and cutting quality, thereby improving the quality of samples for subsequent analysis.

[0036] Reference Figure 3 As shown, in this embodiment: since the two rollers are adjacent, it is very easy to cause accidental touching during the rotation process, affecting normal use. Therefore, an arc-shaped shell 11 is symmetrically provided at the upper end of the gripping rod 1, and a cover plate 12 is slidably installed on the inner side of the arc-shaped shell 11, so that when it is necessary to rotate that roller, the cover plate 12 on the outer side of that roller is opened, thereby effectively avoiding accidental touching of the adjacent rollers.

[0037] Reference Figure 1 、 Figure 3As shown, in this embodiment: in order to improve the stability of the extraction rod 41 and the half rod 421 during horizontal movement, a cavity rod 15 is fixedly installed at the other end of the holding rod 1, and the extraction rod 41 and the half rod 421 are both slidingly connected to the inner wall of the cavity rod 15, so that both ends are supported, thereby effectively improving the stability during movement.

[0038] Reference Figure 3 As shown, in this embodiment: in order to improve the stability of personnel when operating the device, a handle 16 is fixedly installed at the lower end of the gripping rod 1, and a groove for placing fingers is opened on the surface of the gripping rod 1, which significantly improves the operational stability from an ergonomic point of view. The groove can naturally fit the finger shape, making the hand more comfortable when holding, and reducing the shaking of the device caused by unstable grip during operation. At the same time, the grip 16 provides a more stable force fulcrum for the hand, and cooperates with the operation of the gripping rod 1 to allow the doctor to exert force more accurately and controllably when driving the roller and controlling the extraction component 4. Especially in long-term operation or in scenarios with limited surgical field of view, it can effectively reduce hand fatigue and further ensure the stability and accuracy of the extraction action during surgery.

[0039] Working principle: During the operation, when it is necessary to extract the pathological soft tissue for pathological analysis, first align the cover head 3 with the pathological tissue and abut it, then use your fingers to rotate the roller 13, so that the adjusting member 42 gradually moves horizontally in the direction away from the cover head 3. Since the cover head 3 abuts against the pathological tissue and the through-hole disk 32 is connected, a negative pressure is gradually formed inside it to adsorb the pathological tissue, causing part of the pathological tissue to gradually extend into the cover head 3. Then stop rotating the roller 13 and use your fingers to rotate the roller 2 14 again, so that the extraction rod 41 drives the multiple groups of grasping fingers 43 to gradually move horizontally in the direction away from the cover head 3, causing the multiple groups of grasping fingers 43 to simultaneously produce negative pressure with the through-hole disk 32. 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 to ensure that the ball head 444 is always located in the thread groove 445, thereby cutting off the gradually tightened pathological tissue and causing the pathological tissue to remain between the multiple groups of grasping fingers 43. At this time, the rotation of roller 2 14 is stopped and roller 1 13 is reversed to release the negative pressure in the cover head 3, and the case tissue to be analyzed can be extracted.
