Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a specimen preservation device for breast-conserving surgery. Background Technology

[0002] Currently, the rate of breast-conserving surgery for breast cancer in my country is gradually increasing, and it is considered one of the main methods of breast tissue management, alongside traditional mastectomy. The specific procedure for breast-conserving surgery is as follows: First, a suitable incision is selected based on the tumor location, and the tumor and a certain distance of surrounding breast tissue are removed. Then, the excised specimen is carefully marked. Traditional marking methods distinguish the upper, lower, medial, lateral, and base of the specimen, with the core rule being "one upper, two lower, three medial, four lateral." Specifically, one suture is placed at the center point of the upper incision margin, two sutures at the center point of the lower incision margin, three sutures at the medial incision margin, and four sutures at the lateral incision margin; the base and surface are distinguished by the natural anatomical morphology of the specimen, requiring no additional sutures. After labeling, the specimen is placed in a specimen bag and sent to the pathology department for intraoperative frozen section pathology examination. If the frozen section pathology of each resection margin is negative, that is, no tumor cells are found, the next step of the operation can be continued. If the resection margin is positive, that is, tumor cells are found, part of the tissue needs to be removed beyond that resection margin to form a new resection margin, and then sent for examination again. If the new resection margin after the extended resection is still positive, the breast-conserving surgery has failed and a total mastectomy is required.

[0003] In actual clinical practice, the traditional suture marking method has the following prominent problems: 1. After the specimen is retrieved, it is usually placed near the surgical area, and the surgeon or assistant marks the sutures with both hands, which is a tedious operation. During the hand-to-hand transition, the cut edges are easily confused, requiring the surgeon and assistant to repeatedly check and compare them with the surgical cavity to ensure that the marking is accurate.

[0004] 2. Suture marking requires tying knots at the surgical margin to distinguish different margins by the number of sutures. This process is not only cumbersome but also has significant drawbacks: tying knots can cause tearing of the surgical margin tissue, the knots are prone to detachment, and the knotting operation itself causes additional damage to the surgical margin tissue. Pathologists generally do not have time to untie the knots during sampling and will often cut away the tissue containing the knots before starting sampling, resulting in wasted surgical margins. Current trends in breast-conserving surgery are to gradually reduce the distance between the surgical margin and the tumor to preserve normal glandular tissue to the greatest extent possible, making additional damage to the surgical margin tissue particularly regrettable. Furthermore, when pathologists retrieve the specimen from the specimen bag, the specimen is often tangled with sutures, requiring them to first sort the sutures according to their number and restore the surgical margin direction, which is time-consuming. At this time, the patient is still under general anesthesia in the operating room and must wait for the negative frozen section pathology results before continuing with the residual cavity titanium clip marking and suturing, further prolonging the operation time.

[0005] 3. In actual surgery, the distance between the tumor and each surgical margin is difficult to be completely uniform, making it difficult to ensure that all surgical margins maintain a standard distance of 1 cm from the tumor—the resection area of ​​breast-conserving surgery is inherently the tumor and a certain width of surrounding breast tissue. Regarding the specific safe surgical margin distance, the internationally accepted view is that it is safe as long as frozen section pathology confirms the absence of tumor cells at the margin. Internationally, this is generally maintained at 2 mm or more, while in my country, a more conservative treatment strategy is often adopted, with a margin of 1 cm or more in clinical practice. However, the overall trend is to gradually reduce the surgical margin distance. Abandoning suture marking can reduce additional damage to the surgical margin tissue, helping to further reduce the surgical margin distance without affecting complete tumor resection, thus broadening the actual indications for breast-conserving surgery and improving postoperative breast aesthetics.

[0006] Furthermore, after retrieving the specimen, the surgeon typically relies on tactile experience to determine which side of the resection margin is closer to the tumor. For such suspicious margins, two common clinical approaches are used: one is to add additional sutures to mark the margin and note it on the pathology report as requiring focused examination; the other is to directly remove additional tissue from the surgical cavity as an additional margin, which is then sent for examination along with the original specimen. However, the latter method still requires addressing the marking of the new margin—clearly distinguishing between the "tumor-away side" and the "tumor-closer side" of the new margin. Currently, suture marking is still more commonly used, but the procedure is equally cumbersome.

[0007] Therefore, we propose a specimen preservation device for breast-conserving surgery. Summary of the Invention

[0008] The purpose of this invention is to provide a specimen preservation device for breast-conserving surgery, which solves the problem of inconvenience in existing specimen preservation by using a combination of stabilizing components, positioning components, and adjusting components.

[0009] To achieve the above objectives, the present invention provides the following technical solution: A specimen preservation device for breast-conserving surgery includes a base plate with an outer frame at its top. Connecting seats are symmetrically mounted on the outside of the outer frame, and handles are symmetrically mounted on the connecting seats.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] Example 1: As Figure 1 - Figure 8As shown in the diagram, a specimen preservation device for breast-conserving surgery includes a base plate 1 made of medical-grade ABS plastic. This material is high-strength and impact-resistant, capable of withstanding minor collisions during specimen storage and transportation, preventing deformation that could affect the overall structural stability. A counterweight 34 is installed inside the base plate 1. This counterweight 34 is made of high-density cast iron, whose high density effectively lowers the overall center of gravity of the device. Its weight has been precisely calculated to ensure stable placement of the device even when a specimen is placed inside the inner bowl 10, preventing tipping. Anti-slip pads 13 are evenly installed on the bottom of the base plate 1. Furthermore, the counterweight 34 at the bottom further lowers the center of gravity and prevents the device from tipping over. Meanwhile, an anti-slip mat 13 is added. The anti-slip mat 13 is made of medical-grade silicone. Silicone has good elasticity and excellent anti-slip performance, which can further increase the contact friction with the table. The top of the base plate 1 is provided with an outer frame 2. The outer frame 2 and the base plate 1 are made of medical-grade ABS plastic through an integrated injection molding process. The integrated structure enhances the connection strength between the outer frame 2 and the base plate 1, and prevents the connection from loosening after long-term use. The outer frame 2 is symmetrically installed with a connecting seat 3. The connecting seat 3 is made of stainless steel. Stainless steel is corrosion-resistant and easy to clean, and is suitable for repeated disinfection in medical environments. It is fixedly connected to the outer frame 2 by welding. The weld is polished, and the connection is firm and the surface is flat, avoiding sharp protrusions from scratching the operator. Meanwhile, handles 27 are symmetrically installed on the connecting base 3, and anti-slip sleeves 28 are installed on the outside of the handles 27. The anti-slip sleeves 28 are made of medical-grade rubber, which has good elasticity and anti-slip performance. They are inserted into the outside of the handles 27 through an interference fit, making them firmly installed and not easy to fall off. The surface is designed with raised dot texture (not shown in the figure) to increase the friction between the hand and the handles 27, so that even if the hands are contaminated with blood or disinfectant, it can still be lifted steadily. At the same time, the rubber material is soft, which can reduce the discomfort when lifting. It also includes: A stabilizing component 4 is installed inside the outer frame 2. The stabilizing component 4 includes a dual-axis gyroscope 7, on which a silicone damping ring 8 is mounted. The dual-axis gyroscope 7 is a high-precision MEMS dual-axis gyroscope. Its working principle is to sense the tilt changes of the device in the horizontal and vertical directions through two internal orthogonal vibrating mass blocks. When the device tilts or moves, it can detect and feedback the tilt signal in real time, and work with the silicone damping ring 8 to achieve buffering adjustment. A connecting sleeve 9 is installed outside the silicone damping ring 8. The connecting sleeve 9 is made of polycarbonate material with high transparency. The inner bowl 10 is designed to facilitate observation of the specimen's condition by medical staff. Its high rigidity protects the inner bowl 10 from deformation due to external pressure. The connecting sleeve 9 and the inner wall of the outer frame 2 have a clearance fit, facilitating the overall installation and disassembly of the stable component 4 and simplifying subsequent cleaning and maintenance. The inner bowl 10 is made of medical-grade polypropylene, which has good biocompatibility and will not chemically react with the specimen, ensuring its integrity during storage. It is also heat-resistant, adaptable to high-temperature sterilization processes, and meets medical sterilization requirements.

[0023] Please also see Figure 5 The inner bowl 10 is used to store glandular specimens. The silicone damping ring 8 installed on the dual-axis gyroscope 7 is made of high-elasticity medical-grade silicone, possessing excellent damping and shock absorption performance. Its inner side fits tightly against the dual-axis gyroscope 7, while its outer side is firmly connected to the connecting sleeve 9. When the device is subjected to external force, the silicone damping ring 8 effectively absorbs vibration energy through its own elastic deformation, thereby reducing the impact of vibration on the inner bowl 10 and lowering the probability of specimen movement. The inner bowl 10 has evenly spaced graduation lines 11. These graduation lines are laser-engraved, ensuring they remain clearly visible even after long-term use or repeated cleaning. The graduation lines 11 are marked according to clock time: the 12 o'clock position is the upper incision edge, the 6 o'clock position is the lower incision edge, and the 3 o'clock position, if representing a left breast specimen, represents the outer incision edge, and so on. This marking method conforms to the operating habits of medical personnel; the incision edge and position are automatically indicated after the specimen is placed, eliminating the need for sutures, simplifying the operation process, reducing the risk of misjudgment, and minimizing incision edge wear and inaccuracies. With its precise scale markings, it effectively saves time and costs.

[0024] For further details, please refer to Figure 2 The bottom of the inner bowl 10 is provided with a groove 12, which is arc-shaped. The depth and curvature of the groove have been precisely calculated based on ergonomics and specimen storage characteristics. When the gland specimen is placed in the inner bowl 10, the bottom of the specimen can naturally fit into the groove 12. The groove 12 can effectively limit the movement of the specimen and reduce the displacement caused by the shaking of the device during storage or transportation.

[0025] It should be noted that if additional cutting margins are needed immediately during the procedure, the new cutting margin can be directly placed next to the specimen to clearly define its location and lateral edge. Specifically, the new cutting margin specimen is placed next to the original specimen at the sampling location, ensuring close contact. Due to the adhesiveness of fresh tissue and the curved design of the inner bowl, the two can adhere stably. Furthermore, if pathology requires cutting margins in other directions, the surgeon can directly specify the exact angle and direction.

[0026] In addition, a positioning component 5 is installed inside the inner bowl 10 for precise positioning of the gland specimen. An adjustment component 6 is provided on the connecting seat 3 for adjusting the angle of the handle 27. When placing the specimen, the handle 27 can be positioned on the side of the outer frame 2 for easy lifting. During transportation, the adjustment component 6 can fix the handle 27 to prevent it from shifting. This design features graduations, so the cutting edge and position are automatically indicated after the specimen is placed, eliminating the need for sutures, simplifying the operation process, reducing the risk of misjudgment, minimizing cutting edge damage and inaccuracies, and allowing for precise marking of the cutting edge without the need for sutures, thus saving time and costs.

[0027] Please also see Figure 2 The positioning component 5 includes a mounting groove 14 formed on the inner bowl 10. A magnetic snap fastener 15 is installed inside the mounting groove 14. The mounting groove 14 is a circular groove structure with a size that matches the magnetic snap fastener 15. The magnetic snap fastener 15 is bonded and fixed inside the mounting groove 14 with medical-grade epoxy resin adhesive. The adhesive is strong and biocompatible, preventing it from falling off during use.

[0028] The magnetic snap fastener 15 has a snap block 18 inside, and the bottom of the snap block 18 is equipped with a magnetic block 19 that attracts the magnetic snap fastener 15. The attraction between the magnetic snap fastener 15 and the magnetic block 19 will automatically pull the snap block 18 into the mounting groove 14, so that the cover 16 can be quickly snapped together without complicated snapping operations. The magnetic connection is easy to disassemble. Medical staff can easily remove the cover 16 by gently lifting it, which is convenient for taking out and putting in specimens or cleaning the inner bowl 10.

[0029] Furthermore, a cover 16 is installed on the outside of the card block 18. The cover 16 is made of medical-grade silicone, which has good flexibility and biocompatibility, will not contaminate the specimen, and has good elasticity, so it is not easily damaged by slight pressure. Its size is precisely matched with the opening size of the inner bowl 10. A sealing ring 17 is installed at the connection between the cover 16 and the inner bowl 10. The sealing ring 17 is made of food-grade silicone, which has good sealing performance and elasticity. It is fixed to the edge of the cover 16 through a slot. By inserting the card block 18 into the installation groove 14, the cover 16 can be quickly locked. The sealing ring 17 is made of food-grade silicone, which has good sealing performance and elasticity. It is fixed to the edge of the cover 16 through a slot. When the cover 16 is closed on the inner bowl 10, the sealing ring 17 undergoes elastic deformation due to the pressure of the opening edge of the inner bowl 10, filling the gap between the cover 16 and the inner bowl 10, ensuring the sealing of the inner bowl 10 and preventing blood or specimen from spilling out.

[0030] For details, please refer to Figure 4 The cover 16 has a screw 20 internally threaded, and a boss 21 is fixedly connected to one end of the screw 20. The boss 21 is made of medical-grade silicone, which is soft and will not cause squeezing damage when in contact with the specimen. A pressure sensor 22 is installed inside the boss 21. The pressure sensor 22 is a miniature piezoresistive pressure sensor with high accuracy and fast response speed, which can detect the pressure value between the boss 21 and the specimen in real time. A nut 23 is fixedly connected to the end of the screw 20 away from the boss 21. The nut 23 has anti-slip texture. By rotating the nut 23, the screw 20 can be moved, thereby moving the boss 21 to position the specimen. At the same time, the pressure sensor 22 inside the boss 21 can prevent excessive pressure, keeping the specimen fixed and ensuring that it does not deform.

[0031] In addition, the inner wall of the inner bowl 10 is sprayed with an anti-slip silicone coating with a micron-level anti-slip texture. The coating is made of medical-grade anti-slip silicone material, with uniform thickness and special curing treatment. It has strong adhesion and is not easy to fall off. The surface has a micron-level anti-slip texture with a grid-like distribution, which can increase the friction with the specimen. Together with the protrusion 21 for positioning, it forms a double fixation, effectively reducing specimen movement.

[0032] Example 2: Figure 1 - Figure 8As shown, this is a further description of Embodiment 1. In this embodiment, the adjusting component 6 includes limiting holes 24 evenly distributed on the connecting seat 3. The limiting holes 24 are processed by drilling, and the hole diameter is precisely matched with the size of the ball bearing 32 to ensure that the ball bearing 32 can be smoothly inserted. They are evenly distributed in a ring on the connecting seat 3, and the angle between adjacent limiting holes 24 is the same, which facilitates multi-angle precise adjustment of the handle 27 to meet the needs of different usage scenarios. The connecting seat 3 is rotatably connected to a rotating shaft 25, and a connecting block 26 is fixedly connected to the outside of the rotating shaft 25. The connecting block 26 is fixedly connected to the handle 27. The connecting block 26 is made of aluminum alloy, which is lightweight and high-strength, which can reduce the overall weight of the handle 27, making it easy to carry. It is also corrosion-resistant and suitable for use in medical environments. The connecting block 26 is fixedly connected to the handle 27 by welding. The weld is reinforced to withstand the pulling force when the handle 27 is lifted, preventing breakage after long-term use.

[0033] For details, please refer to Figure 6 and Figure 8 The connecting block 26 has a slot 33 inside. The slot 33 is a cylindrical slot structure with a size that matches the spring 29 and the turntable 30, ensuring that the spring 29 and the turntable 30 can move smoothly inside the slot 33. The spring 29 is installed inside the slot 33. The spring 29 is made of stainless steel spring steel, which has good elasticity and fatigue strength and can withstand repeated compression and rebound. It can maintain good elasticity even after long-term use. The turntable 30 is fixedly connected to the outside of the spring 29.

[0034] Furthermore, the turntable 30 is internally connected with ball bearings 32, which are made of bearing steel. These ball bearings are hard, wear-resistant, and can withstand friction and compression during rotation. They are not easily worn out during long-term use. A limit ring 31 is installed on the outside of the ball bearings 32. The limit ring 31 is made of plastic and is fixed inside the turntable 30 through a slot. It can limit the ball bearings 32 and prevent them from falling out of the turntable 30. This ensures that the ball bearings 32 always rotate inside the turntable 30 and contact the inner wall of the connecting seat 3 or the limit hole 24. When the ball bearing 32 is not engaged in the limiting hole 24, the spring 29 is in a naturally extended state, pushing the turntable 30 to move towards the opening of the slot 33; when the handle 27 is turned, the connecting block 26 drives the rotating shaft 25 to rotate, and the ball bearing 32 is squeezed into the slot 33 by the inner wall of the connecting seat 3, compressing the spring 29; when the ball bearing 32 rotates to the position of the limiting hole 24, the spring 29 pushes the turntable 30 to move, so that the ball bearing 32 is engaged in the limiting hole 24, thus positioning the handle 27.

[0035] In summary, when using this device, firstly, after the gland specimen is placed in the inner bowl 10, it is initially positioned by the arc-shaped groove 12 at the bottom of the inner bowl 10, with the bottom of the specimen naturally embedded in the groove 12, reducing lateral displacement. Simultaneously, the micron-level mesh texture of the anti-slip silicone coating on the inner wall of the inner bowl 10 increases the friction with the specimen surface, forming the first layer of fixation. Subsequently, when closing the cover 16, the locking block 18 is aligned with the mounting groove 14 of the inner bowl 10. The magnetic force of the magnetic buckle 15 and the magnetic block 19 automatically attracts the locking block 18, quickly fixing the cover 16. The sealing ring 17 deforms under pressure to fill gaps and ensure a seal. Rotating the nut 23 moves the screw 20 along the internal thread of the cover 16, causing the boss 21 to approach and contact the specimen. The pressure sensor 22 inside the boss 21 detects the contact pressure in real time. When the pressure reaches a suitable fixed value, rotation stops to prevent specimen deformation under pressure. Combined with the anti-slip coating, this forms a dual positioning system, ensuring the specimen's stable position during storage. Secondly, when the device is placed, the high-density cast iron counterweight 34 inside the base plate 1 lowers the overall center of gravity, preventing the device from tipping over due to the weight of the inner bowl 10 or the tilt of the table. The wavy texture of the medical silicone anti-slip pad 13 at the bottom of the base plate 1 increases the friction with the contact surface, preventing the device from sliding on the operating table or trolley. When the device is shaken by external forces or moved during transportation, the stabilizing component 4 inside the outer frame 2 activates protection: the dual-axis gyroscope 7 senses the tilt signals in the horizontal and vertical directions through the internal orthogonal vibration mass block, and the silicone damping ring 8 undergoes elastic deformation accordingly, absorbing vibration energy and buffering impact force, reducing the impact of shaking on the inner bowl 10; the connecting sleeve 9 serves as the outer protective structure of the inner bowl 10, preventing the inner bowl 10 from being deformed by external pressure, and its transparent characteristics facilitate observation of the specimen's condition. Multiple protections ensure that the specimen is not damaged or displaced during movement. Finally, during operation, the clock-like scale lines 11 laser-engraved inside the inner bowl 10 directly indicate the cutting edge direction, with 12 o'clock corresponding to the upper cutting edge, 6 o'clock to the lower cutting edge, etc., clearly defining the specimen position without sutures. When placing a new cutting edge, the specimen can be placed directly next to the original specimen according to the sampling position, ensuring a close fit and avoiding confusion. When adjusting the angle of the handle 27, holding the handle 27 drives the connecting block 26 and the rotating shaft 25 to rotate within the connecting seat 3. At this time, the ball bearing 32 is pressed into the slot 33 by the inner wall of the connecting seat 3, compressing the spring 29. When rotated to the target angle, the ball bearing 32 aligns with the limiting hole 24 on the connecting seat 3, and the spring 29 elastically returns to its original position, pushing the turntable 30 so that the ball bearing 32 engages with the limiting hole 24, thus positioning the handle 27. When placing a specimen, the handle 27 can be adjusted to the side of the outer frame 2 to avoid obstructing operation, and during transportation, it can be adjusted to a suitable direction for easy lifting, improving the convenience of operation and delivery.
