Technical Field

[0001] This utility model relates to the field of placental chorionic membrane peeling technology, specifically a device for precise peeling of placental chorionic membrane. Background Technology

[0002] Placental chorion removal is a crucial procedure in obstetrics and medical research. The placental chorion is an essential component of placental tissue, and its complete removal facilitates subsequent medical testing, pathological analysis, and scientific research. In practice, the chorion needs to be effectively separated from other tissues to ensure the purity and integrity of the obtained sample. Traditional removal methods often rely on manual operation, resulting in low efficiency and insufficient separation precision. Therefore, specialized equipment is needed to achieve more standardized, stable, and precise removal results. Such equipment aims to improve the standardization of the procedure and meet the accuracy and reliability requirements for placental tissue processing in medical and research settings.

[0003] In existing technologies, traditional placental chorionic villus stripping relies heavily on manual operation, which has problems such as limited recognition accuracy and poor cutting consistency, and is prone to causing tissue residue or damage. On the other hand, some cutting devices lack integrated negative pressure collection and electronic control coordination functions, requiring multiple manual transfers and cleanings during the operation process, which is inefficient and prone to introducing the risk of contamination.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 As shown, this utility model provides a technical solution:

[0022] A device for precise removal of placental chorionic membrane includes a feed trough 101, which is installed through one side of the top of a housing 102. Discharge holes 103 are respectively opened on both sides of the feed trough 101 along its length and inside the housing 102. An observation groove 104 extends from one side of the feed trough 101 along its width and inside the housing 102, and an optical recognition module 105 is installed through the observation groove 104. A cutting blade 106 extends through the other side of the feed trough 101 along its width and inside the housing 102. The cutting blade 106 has a certain gap with the feed trough 101 and is fixedly mounted at the output end of a vibrating cutter 107. A corrugated pipe 108 is provided at the gap between the housing of the vibrating cutter 107 and the feed trough 101.

[0023] The above scheme enables the feeding trough to support and guide the pre-treated placental tissue blocks, the box body to provide structural support and internal space for the overall device, the discharge hole to achieve effective output of the cut material and establish a negative pressure suction channel, the observation trough to provide a clear field of view for optical observation, the optical recognition module to accurately identify and locate the tissue boundary, the cutting blade to perform high-frequency vibration cutting to separate the target tissue, the vibrating cutter to provide high-frequency micro-amplitude power output for the cutting action, and the bellows to seal the dynamic connection and prevent tissue debris leakage.

[0024] In this embodiment, preferably, a limiting slip ring 109 is fixedly installed on one side of the vibratory cutter 107, and the limiting slip ring 109 is slidably installed on the outside of the limiting slide rod 110. The limiting slide rod 110 is hollow inside and is slidably provided with a magnetic block 111. The magnetic block 111 is magnetically attracted and fixed to the limiting slip ring 109.

[0025] The above scheme enables reliable connection and guidance between the vibratory cutter and the sliding mechanism through the limiting slip ring, provides a stable motion trajectory and structural support for the sliding component through the limiting slide rod, and enables rapid positioning and stable fixation of the sliding component through the magnetic block using magnetic force.

[0026] In this embodiment, preferably, the limiting slide bar 110 is fixedly installed on one side inside the housing 102, the optical recognition module 105 is installed on the other side inside the housing 102 by bolts, and a negative pressure fan 112 is fixedly installed inside the housing 102 adjacent to the optical module.

[0027] The above solution provides a stable installation base for the optical recognition module and the negative pressure fan. The optical recognition module enables image acquisition and intelligent recognition, while the negative pressure fan generates the negative pressure airflow required by the system to achieve suction and cleaning.

[0028] In this embodiment, preferably, the suction end of the negative pressure fan 112 is connected to the output end of the collection box 113 and both ends of the limiting slide rod 110 through a diversion pipe, and the diversion pipe is connected in series with a solenoid valve 114. The input end of the collection box 113 is connected to the discharge hole 103 through a pipe.

[0029] The above scheme provides a stable negative pressure power source for the system through a negative pressure fan, distributes and transports airflow between different actuators through a diversion pipe, controls the flow and flow of the airflow channel through a solenoid valve, classifies and temporarily stores the separated materials through a collection box, and uses the discharge port as the channel interface for materials to enter the collection box.

[0030] In this embodiment, preferably, the collection boxes 113 symmetrically extend into the lower part of the box body 102, and a control box 115 is fixedly installed on the top of the box body 102 adjacent to the feed trough 101. The control box 115 is inclined, and a touch screen 116 is installed through the inclined part.

[0031] The above solution allows operators to easily retrieve and process collected materials through the collection box, maintains the integrity of the overall structure and protects internal components through the box body, provides centralized installation and protection space for the electrical control system through the control box, and enables human-machine interaction, input of operation commands, and status display through the touch screen.

[0032] In this embodiment, preferably, a circuit board 117 is bolted to the bottom of the control box 115, and the corresponding connectors of the circuit board 117, the touch screen 116, the negative pressure fan 112, the vibratory cutter 107 and the optical recognition module 105 are connected by flexible wires.

[0033] The above solution provides mechanical protection and electromagnetic shielding for internal electronic components through the control box, enables signal processing and control logic operations between devices through the circuit board, ensures the reliability and vibration resistance of the connections between electrical components through flexible wires, and coordinates the orderly and collaborative operation of optical recognition, negative pressure suction and vibration cutting functions through the overall electronic control system.

[0034] In this embodiment, a device for precise removal of placental chorionic membranes is used such that, during operation, the operator places a pre-cut and saline-washed block of placental tissue into the feed trough 101. The feed trough 101 is installed through the top of the housing 102 on one side, and discharge holes 103 are provided on both sides along its length inside the housing 102. After the negative pressure fan 112 is started, suction is performed through the diversion pipe. A solenoid valve 114 connected in series on this pipe is used to precisely control the airflow path, so that the negative pressure fan 112 can simultaneously act on the output end of the collection box 113 and the limiting slide rod 110. At both ends; the input end of the collection box 113 is connected to the discharge hole 103 through a pipe, thereby forming a uniform negative pressure environment in the feeding trough 101, stably adsorbing and guiding the tissue block to slide down automatically and be accurately positioned; during the tissue block transportation process, the observation groove 104 formed by extending from the middle of the feeding trough 101 along one side of the width direction provides a field of view for the optical recognition module 105. The optical recognition module 105 scans the tissue surface and accurately identifies the boundary features between the chorion, blood vessels and the maternal flesh, providing key visual positioning data for subsequent cutting operations.

[0035] Based on the positioning information provided by the optical recognition module 105, the vibratory cutter 107 starts working, driving the cutting blade 106 at its output end to perform high-precision high-frequency micro-amplitude vibration. The cutting blade 106 penetrates the feed trough 101 along the other side of its width direction and maintains a precise gap with the trough body. This gap is completely sealed by the bellows 108, which ensures flexibility during the cutting process and prevents the leakage of biological particles. During the cutting process, the negative pressure fan 112 sends controllable airflow into the limiting slide bar 110 through the diversion pipe, driving the magnetic block 111 inside the hollow limiting slide bar 110 to slide. The magnetic block 111 drives the limiting slip ring 109 fixed on the housing of the vibratory cutter 107 through magnetic force, so that the entire vibratory cutter 107 can move smoothly along the limiting slide bar 110, ultimately achieving precise control of the working position of the cutting blade 106 and completing the film peeling operation.

[0036] After the separation is completed, the successfully separated membrane tissue and residue are sucked into different collection boxes 113 through the discharge holes 103 on both sides of the feed trough 101 under the continuous suction of negative pressure, achieving automatic separation and collection. The entire process is coordinated by the control box 115, which is fixed at an angle to the top of the box 102 near the feed trough 101. The touch screen 116 installed on its inclined surface provides the operator with a clear and convenient human-machine interface. Inside the control box 115, the circuit board 117 is fixed to the bottom with bolts and is connected to the touch screen 116, negative pressure fan 112, vibrating cutter 107 and optical recognition module 105 through flexible wires, forming a complete intelligent control system. This ensures the timing and coordination of the actions of each component, and finally realizes the precise and automated peeling and sorting of placental chorionic membrane, significantly improving the reliability, hygiene standards and overall efficiency of the operation.
