Abstract
Description
Technical Field
[0001] This utility model relates to a medical auxiliary device for rapid intraoperative pathological examination, and more particularly to a fixation device for breast specimens. Background Technology
[0002] In the surgical treatment of breast segments, intraoperative rapid pathological examination is crucial for determining the cleanliness of tumor margins and guiding the surgical scope. In routine procedures, intraoperative specimens are sent to multiple sites for rapid examination. To achieve accurate localization, surgeons typically suture different numbers of sutures at corresponding sites on the specimen to distinguish different margin directions, facilitating identification and sample collection by pathologists. However, in practice, there is a risk of suture breakage. For example, sutures of the same number may be sutured at different sites. If pathologists cannot accurately identify the specimen orientation, improper sample collection may occur, affecting intraoperative pathological assessment and surgical outcomes. If a broken suture is not detected and corrected promptly, the specimen may be confused during transport due to incorrect suture number or marking. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to provide a fixation device for breast specimens that provides clear identification, secure specimen fixation, and avoids identification confusion due to incorrect suture quantity or label position.
[0004] To solve the above-mentioned technical problems, the fixation device for breast specimens of this utility model includes a disc-shaped fixation plate. The center of the fixation plate has a groove for placing the specimen. The fixation plate has multiple strip grooves that extend radially from the edge of the groove to the edge of the fixation plate. The back of the fixation plate has multiple clamping devices that correspond to the positions of each of the grooves. The specimen is sutured with sutures of different colors to mark different parts. The clamping device includes a shell with an open top and an inner cavity, thread holes on the front and rear side walls of the shell, and an elastic suture clamping assembly that can reciprocate in the inner cavity. The elastic suture clamping assembly has a through hole that can align with the thread hole when the elastic suture clamping assembly is in the lower limit position to form a through channel for the suture to pass through. Each suture can extend through different strip grooves to the corresponding clamping device and pass through the through channel. After the suture is fixed by releasing the elastic suture clamping assembly, the suture is fixed.
[0005] The elastic thread clamping assembly includes a spring fixedly installed at the bottom of the inner cavity and an elastic locking post pressed on the top surface of the spring and capable of reciprocating up and down within the inner cavity. A through hole is provided on the elastic locking post and can align the through hole with the thread hole when the elastic locking post is in the lower limit position to form a through channel for the sewing thread to pass through. At the same time, the sewing thread is tightened and fixed when the spring is in the elastic release state.
[0006] The elastic locking post is provided with two through holes, and the front and rear side walls of the outer shell are provided with two pairs of wire holes corresponding to the two through holes. The wire hole located on the lower part of the front side wall of the outer shell is set as a guide groove. The lower front part of the elastic locking post is provided with an elastic arm that extends out of the guide groove and can move up and down in the guide groove. The elastic arm is provided with a wire hole corresponding to the position of the through hole.
[0007] The elastic buckle has a T-shaped cross-section and its upper end extends out of the upper opening of the outer shell as a pressing part. When the elastic buckle is in the pressing state, the through hole and the wire hole are at the same horizontal position and match to form a through channel.
[0008] The inner surface of the elastic arm is provided with an L-shaped pressure groove, and the front side wall of the outer shell is provided with a pressure block located above the guide groove for cooperating with the pressure groove to press the seam.
[0009] The strip grooves are distributed radially.
[0010] The fixing plate is provided with 6 strip grooves, each of which has markings for identifying the upper cutting edge, lower cutting edge, anterior cutting edge, posterior cutting edge, inner cutting edge, and outer cutting edge of the specimen.
[0011] The bottom of the inner cavity of the clamping device is provided with a protrusion for positioning the spring.
[0012] The grooves are divided into sections for marking by filling them with different colored marking coatings, pasting text labels, or embedding different colored strips.
[0013] Advantages of this utility model: (1) Clear identification: By equipping different colored sutures with different cutting edge directions, each suture is visually unique, which improves the intuitiveness and accuracy of cutting edge identification, making it easier for pathologists to quickly locate the sampling site during the pathological examination, significantly reducing sampling deviations caused by suture confusion, breakage and other problems, and improving the efficiency and accuracy of pathological examination.
[0014] (2) Accurate positioning: Each suture passes through the strip groove on the fixed plate in sequence and is then guided into the clamping device, forming a continuous guide path from the specimen to the strip groove to the clamping device. It can also achieve the shortest path guidance of the suture from the specimen to the clamping device, avoiding problems such as suture crossing and tangling, and mutual obstruction.
[0015] (3) Stable structure: The clamping device can quickly clamp and lock the end of the suture. The elastic buckle can move up and down under the action of the spring, and a clamping channel is formed by the through hole on the buckle that can cooperate with the side wall of the outer shell. After the suture is introduced through the thread hole, the buckle can be released to quickly achieve automatic clamping. This structure makes the suture fixing operation simple and efficient, effectively prevents the suture from falling off or shifting, improves the accuracy and reliability of specimen orientation indication, and is suitable for high-frequency, multi-directional suture fixing application scenarios.

Detailed Implementation
[0017] The fixation device for breast specimens of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. Example
[0018] The breast specimen fixation device of this utility model includes a disc-shaped fixation plate 1. The fixation plate 1 has a groove 2 at its center for placing the specimen. The specimen is sutured with different colored sutures 5 to identify different parts of the specimen. The colors of the sutures 5 include red, yellow, purple, orange, green, and blue, representing the upper incision edge, lower incision edge, anterior incision edge, posterior incision edge, inner incision edge, and outer incision edge, respectively. The fixation plate 1 has six radially extending grooves 3 from the edge of the groove 2 to the edge of the fixation plate. The grooves 3 are radially distributed, and different colored marking coatings, text labels, or inlays are used to fill the grooves 3. Color bars of the same color are used for partition marking; multiple clip devices 4 are provided on the back of the fixed motherboard, each corresponding to the position of the groove 2. The clip device 4 includes a shell 6 with an open top and an inner cavity, wire holes penetrating the front and rear side walls of the shell 6, and an elastic wire clamping assembly 7 that can reciprocate in the inner cavity. The bottom of the inner cavity of the clip device 4 is provided with a protrusion 15 for positioning the spring. The elastic wire clamping assembly includes a spring 10 fixedly installed on the upper surface of the protrusion 15 and an elastic clamping post 8 that presses against the top surface of the spring 10 and can reciprocate up and down in the inner cavity. Through holes are provided in the elastic clamping post 8. The upper part can align the through hole with the thread hole when the elastic locking post 8 is in the lower limit position to form a through channel for the sewing thread 5 to pass through. At the same time, the sewing thread 5 is tightened and fixed when the spring 10 is in the elastic release state. The elastic locking post 8 is provided with two through holes 14. The front and rear side walls of the outer shell 6 are provided with two pairs of thread holes corresponding to the two through holes. The thread hole located on the lower part of the front side wall of the outer shell 6 is set as a guide groove. The lower front part of the elastic locking post 8 is provided with an elastic arm 9 that extends out of the guide groove and can move up and down in the guide groove. The elastic arm 9 is provided with a thread hole corresponding to the position of the through hole. The elastic locking post 8 has a T-shaped cross-section and its upper end extends out of the upper opening of the outer shell 6 as a pressing part. When the elastic locking post 8 is in the pressing state, the through hole and the thread hole are at the same horizontal position and match to form a through channel. The inner surface of the elastic arm 9 is provided with a pressing groove with an L-shaped cross-section. The front side wall of the outer shell 6 is also provided with a pressing block 16 located above the guide groove for cooperating with the pressing groove to press the sewing thread. Each sewing thread 5 can extend through different strip grooves 3 to the corresponding clamping device 4 and be threaded through the through channel. After that, the sewing thread is fixed by releasing the elastic locking assembly.
[0019] Specifically, the elastic locking assembly 7 includes an integrally formed elastic locking post 8 and an elastic arm 9. The elastic locking post 8 has a T-shaped structure and its upper end extends out of the upper opening of the outer shell 6 for pressing control. The elastic locking post 8 has a pair of through locking post through holes 14 corresponding to the position of the threading hole. When the elastic buckle 7 is in the pressed state, the locking post through holes 14 and the threading hole are at the same horizontal position and matched in size to form a through channel. The front side wall of the outer shell 6 has a front threading hole 11 on the same vertical plane and a guide groove 12 that runs through the inside and outside of the outer shell. The rear side wall of the outer shell 6 has two rear threading holes 13. The elastic arm 9 extends from the lower end of the elastic locking post 8 and extends outward through the guide groove 12. The elastic arm 9 is provided with a horizontal position that is the same as the lower rear threading hole when the spring 10 is in the lower limit position. The clamping through hole is used to press the elastic locking post 8 so that the spring 10 is in the lower limit position. At this time, the locking post through hole is aligned with the thread hole of the outer shell to form a through channel for the sewing thread 5 to pass through. The sewing thread 5 is then passed through the thread hole, guide groove 12, lower locking post through hole, lower rear thread hole, upper rear thread hole, upper locking post through hole and front thread hole 11 on the elastic arm 9 in sequence. Then, the elastic locking post 8 is released so that the spring 10 is in a relaxed state. At this time, the elastic locking post 8 will move upward under the action of the spring 10. On the one hand, the elastic arm 9 combined with the pressure block 16 will be in the upper limit of the guide groove 12 and realize the clamping device 4 to clamp and fix the sewing thread 5. On the other hand, the sewing thread 5 located in the rear thread hole 13 is also effectively clamped, so that the sewing thread is fixed in a maze-like path.
