Description

Technical Field

[0001] The utility model belongs to the technical field of rotary cutting needle handle identification systems, in particular to a dual-mode rotary cutting handle access identification system. Background Art

[0002] The mainstream breast biopsy and excision equipment on the market is suitable for medical institutions that can perform surgical operations and imaging diagnosis. It is used for complete or partial excision of breast tissue and palpable breast lesions in a minimally invasive manner for cutting and sampling. Its working principle is as follows: Breast biopsy and excision equipment generally consists of a host, a handle, an excision biopsy needle and a vacuum pipeline system; the handle has a drive motor, which is connected to the host through the handle interface. The host has a vacuum pump, a vacuum barrel, a vacuum pipeline control valve and a main control unit. The main control unit has a handle motor drive circuit. The handle interface and cable control handle motor perform cutting and peeling actions; the vacuum pipeline system connects the peeling biopsy needle to the vacuum barrel on the upper part of the main unit, and the vacuum barrel is connected to the vacuum pump in the main unit. The vacuum pump provides a stable vacuum negative pressure for the system to suck the sample into the sampling slot of the peeling biopsy needle. After the peeling biopsy needle cuts the sample, the sample is sucked into the sample collection chamber through the inner cavity of the inner needle tube under vacuum negative pressure. According to the form of the peeling biopsy needle sample collection chamber, there are two mainstream peeling biopsy needles on the market, one is an open sampling peeling biopsy needle, and the other is a closed sampling peeling biopsy needle.

[0003] In the prior art, one host provides both an open handle interface and a closed handle interface, saving space in hospital operating rooms; however, the existing host has the following deficiencies: 1. The two working modes are integrated on one host, and the host does not recognize the open handle and the closed handle. The operator needs to select the working mode when starting the machine. If the operator is not skilled, the wrong mode may be selected, causing abnormal conditions in the host; at the same time, since the host and the handle may have technical upgrades, the upgraded host may not be able to adapt to the handle before the upgrade; 2. The assembly quality of the rotary biopsy needle is not inspected when it is assembled to the handle. If it is not assembled in place, the handle drive mechanism may be damaged or the quality of the operation may be affected. Utility Model Content

[0004] In view of the above problems, the utility model provides a dual-mode rotary cutting handle access identification system, which stores the handle model information through a storage device. When the handle is connected to a host, the host can read the information recorded in the storage device, and the host automatically enters the working mode corresponding to the connected handle, thereby avoiding equipment abnormalities caused by incorrect working mode selection; and a photoelectric sensor is used to avoid the situation where the rotary cutting biopsy needle is not properly assembled.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A dual-mode rotary cutting handle access identification system includes a control module arranged in a host, a storage device and a sensor arranged in an open handle and a closed handle;

[0007] The storage includes an open handle storage and a closed handle storage, and the storage is used to record handle information; the storage is connected to the control module, and is used to transmit the handle signal to the controller module; the controller module is used to identify the handle signal and control the host to start the corresponding control system;

[0008] The sensor is used to detect whether the biopsy needle is assembled to the handle. The sensor is connected to the control module and is used to feed back the assembly status of the biopsy needle to the handle to the control module.

[0009] As a further improvement of the above technical solution, the sensor includes a first sensor, a second sensor and a third sensor; the first sensor is arranged in the open handle, for detecting whether the rotary cutting needle in the open handle is assembled in place, and the second sensor and the third sensor are arranged in the closed handle, for detecting whether the rotary cutting needle in the closed handle is assembled in place.

[0010] As a further improvement of the above technical solution, the open handle storage is connected to the control module via an SPI interface; the closed handle storage is connected to the control module via an SPI interface.

[0011] As a further improvement of the above technical solution, the second sensor is used to detect the presence or absence of the closed rotary biopsy needle, and the third sensor is used to detect whether the closed rotary biopsy needle is assembled in place.

[0012] As a further improvement of the above technical solution, the first sensor, the second sensor and the third sensor are reflective photoelectric sensors, and the first sensor, the second sensor and the third sensor are connected to the control module via an SPI interface.

[0013] As a further improvement of the above technical solution, the control module adopts STM32F446 as the main control chip, and the control module CLK, MISO, and MOSI are respectively connected to the CLK, SO, and SI ports of the EEPROM chips on the two handles; PB10 is used for chip write protection control to prevent accidental write operations, and PD8 and PE15 are respectively used as chip select signals of the EEPROM chips of the open handle and the closed handle.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows: when a handle is inserted, the host reads the data stored in the EEPROM on the handle when it is powered on, identifies the handle model and version, checks the compatibility of the handle, and automatically enters the working mode corresponding to the connected handle when an adaptable handle is connected, avoiding device abnormalities caused by incorrect working mode selection. At the same time, the host will identify the handle version to automatically adopt a control strategy that is compatible with the version. This technical solution can effectively solve the problem of automatic adaptation of the host to the old and new versions of the handle after the host and the handle are upgraded. By testing the assembly quality of the rotary biopsy needle on the closed handle and the open handle, it is ensured that the assembly is in place, avoiding failures during the operation due to assembly problems and damage to the handle transmission mechanism.

[0023] In order to enable those skilled in the art to better understand the technical solution of the utility model, the utility model is described in detail below in conjunction with the embodiments. The description in this section is only exemplary and explanatory and should not have any limiting effect on the protection scope of the utility model.

[0024] An open handle interface and a closed handle interface are respectively provided on the main body of the rotary biopsy device. The control module provides SPI communication lines to the two handle interfaces. There is a storage circuit with an SPI interface in each of the two handle plugs, which is connected to the control module. Handle information such as handle model, version number, serial number, production date and other information is stored in the storage. When any handle is plugged into the interface, the main control unit will automatically read the stored data in the storage of the two handle interfaces through the SPI interface after the main body is powered on, and identify the handle model and version. The main body automatically enters the working mode adapted to the main body and adopts the control strategy adapted to the corresponding version.

[0025] The open handle and the open biopsy needle are combined in an axial insertion manner, and a first sensor is arranged at the insertion position. When inserted into position, the biopsy needle housing blocks the first sensor, and the photocurrent of the first sensor increases. The current is converted into a voltage signal and sent to the main control unit. The main control unit determines that the biopsy needle is in place based on the signal. When the main control unit does not detect the photocurrent signal, it determines that the handle is not loaded with the biopsy needle or is not in place.

[0026] The closed handle and the closed biopsy needle are assembled in a snap-on manner. When the handle is in place, the gap between the biopsy needle and the handle is small (less than 0.3 mm). If the handle is not in place, there is a large gap (greater than 1 mm) between the handle and the biopsy needle. The same reflective photoelectric sensor as the open handle, i.e., the second sensor, is used to detect the gap. When the biopsy needle is in place, there is no reflection distance between the second sensor and the biopsy needle, and the photocurrent of the second sensor is extremely small. When the biopsy needle is not in place, the photocurrent of the second sensor increases due to the reflection distance. The photocurrent signal is converted into a voltage signal and input into the main control unit for detection. The main control unit can determine that the biopsy needle is not in place. Because the photocurrent is extremely small when the closed handle is not equipped with the biopsy needle and when the biopsy needle is in place, the main control unit cannot distinguish. Therefore, another photoelectric sensor, i.e., the third sensor, is added to detect whether the biopsy needle is installed. The second sensor and the third sensor are arranged in parallel, but the height of the third sensor for detecting the presence or absence of the biopsy needle is 2 to 4 mm lower to ensure a certain reflection distance.

[0027] The closed handle is equipped with two reflective photoelectric sensors, namely the second sensor and the third sensor. In the correct assembly position, the third sensor maintains a distance of 2 to 4 mm from the reflective surface of the closed rotary biopsy needle to detect whether the rotary biopsy needle is assembled to the handle, and the second sensor is close to the reflective surface of the rotary biopsy needle. When the closed rotary biopsy needle is assembled in place, the reflection distance is too small and the photocurrent of the second sensor is small; when it is not assembled in place, the gap increases and the photocurrent of the second sensor is large. The combination of the two sensor states can determine whether the closed rotary biopsy needle is assembled in place.

[0028] Table 1 is the signal logic state table of reflective photoelectric sensor 1 and reflective photoelectric sensor 2 (large photocurrent is 1, small photocurrent is 0):

[0029] Table 1: Logic table for detecting the assembly status of closed rotary biopsy needles

[0030] When the control module determines that the rotary cutting biopsy needle is correctly assembled on the handle based on the sensor signal, it prompts the operator to perform subsequent operations through the human-machine interface. When the rotary cutting biopsy needle is not assembled correctly, the main control unit can prompt the operator to reassemble it through the human-machine interface. Example

[0031] A dual-mode rotary cutting handle access identification system includes a control module arranged in a host, a storage device and a sensor arranged in an open handle and a closed handle;

[0032] The storage includes an open handle storage and a closed handle storage, and the storage is used to record handle information; the storage is connected to the control module and is used to transmit the handle signal to the controller module; the controller module is used to identify the handle signal and control the host to start the corresponding control system;

[0033] The sensor is used to detect whether the biopsy needle is assembled to the handle. The sensor is connected to the control module and is used to feed back the assembly status of the biopsy needle to the handle to the control module.

[0034] As a preferred embodiment of the above embodiment, the sensor includes a first sensor, a second sensor and a third sensor; the first sensor is arranged in the open handle to detect whether the rotary cutting needle in the open handle is assembled in place, and the second sensor and the third sensor are arranged in the closed handle to detect whether the rotary cutting needle in the closed handle is assembled in place.

[0035] As a preferred embodiment of the above embodiment, the open handle storage is connected to the control module via an SPI interface; the closed handle storage is connected to the control module via an SPI interface.

[0036] As a preferred embodiment of the above embodiment, the second sensor is used to detect the presence or absence of the closed rotary biopsy needle, and the third sensor is used to detect whether the closed rotary biopsy needle is assembled in place.

[0037] As a preferred embodiment of the above embodiment, the first sensor, the second sensor and the third sensor are reflective photoelectric sensors, and the first sensor, the second sensor and the third sensor are connected to the control module via an SPI interface.

[0038] As a preferred embodiment of the above embodiment, the control module adopts STM32F446 as the main control chip, and the control module CLK, MISO, and MOSI are respectively connected to the CLK, SO, and SI ports of the EEPROM chips on the two handles; PB10 is used for chip write protection control to prevent accidental write operations, PD8 and PE15 are respectively used as chip select signals of the EEPROM chips of the open handle and the closed handle; D1~D6 are ESD protection devices.

[0039] The memory model used in this embodiment is 25AA02UID.

[0040] The main control unit on the host in this embodiment uses STM32F446 as the main control chip (U1). The chip has a standard ISP interface. Its CLK, MISO, and MOSI are respectively connected to the CLK, SO, and SI ports of the EEPROM chips on the two handles. PB10 is used for chip write protection control to prevent miswrite operations. PD8 and PE15 are respectively used as chip select signals for the open handle and closed handle EEPROM chips. D1~D6 are ESD protection devices, and U2, U3, U5, and U6 are logic gate circuits, which are used as signal drivers here to improve the reliability of signal transmission.

[0041] When any handle is plugged into the interface, the control module will automatically read the data of the storage of the open handle and the closed handle interface through the SPI interface after the host is powered on. If the data cannot be read or the model is incorrect, it will return to re-read the data. When the closed handle model is identified, the system automatically enters the closed sampling mode and selects the corresponding closed handle control strategy based on the version information of the read handle. When the open handle model is identified, the system automatically enters the open sampling mode and selects the corresponding open handle control strategy based on the version information of the read handle.

[0042] The detection of the correctness of the assembly of the open handle and the open rotary biopsy needle is described by the following embodiment: a first sensor 10 is installed on the open handle 5, wherein the first sensor is a reflective photoelectric sensor, and its position is as shown in the attached Figure 5 As shown:

[0043] As attached Figure 4 When assembled in place, the open-type biopsy needle 4 blocks the first sensor 10. The first sensor 10 emits light through the transmitting tube 12. The receiving tube 11 receives the light signal through the reflection of the biopsy needle shell, and the photocurrent increases. The control module can determine that the open-type biopsy needle is assembled in place.

[0044] As attached Figure 5Because the open-type biopsy needle 4 does not block the first sensor 10, the photoelectric sensor receiving tube 11 cannot receive the light signal of the transmitting tube 12, and the photocurrent is small. The control module can determine that the biopsy needle is not installed or is not installed in place; the control module prompts the operator to reassemble it through the human-machine interface.

[0045] In this embodiment, the second sensor and the third sensor are both reflective photoelectric sensors. The reflective photoelectric sensor uses the Omron EE-SY169B micro photoelectric sensor [reflective type], which can achieve high-precision detection of ± 0.6mm. This accuracy can meet the use requirements. Figure 7 EE-SY169B reflection distance characteristic: during assembly, the top surface of the first sensor 10 and the open-type rotary biopsy needle must maintain a reflection distance of 2 to 6 mm.

[0046] The closed handle and the closed biopsy needle are assembled in a snap-fit ​​manner. When snapped into place, the gap between the biopsy needle and the handle is small (less than 0.3 mm). If not snapped into place, there is a large gap between the handle and the biopsy needle (greater than 1 mm).

[0047] As attached Figure 6 The closed handle is provided with a third sensor 32 for detecting the assembly status and a second sensor 31 for detecting the presence of the closed rotary biopsy needle; the structural installation requirements are as follows: the second sensor 31 is used to detect the presence of the closed rotary biopsy needle 7, and it is necessary to ensure that there is a certain gap when the closed rotary biopsy needle 7 is installed on the handle. In the embodiment, the gap d is 2~4mm. When the closed rotary biopsy needle 7 is installed on the handle, the photoelectric receiving tube can receive the reflected signal, and the main control unit determines that the closed rotary biopsy needle 7 is connected to the handle; the third sensor 32 is ensured to be close to the closed rotary biopsy needle 7 when assembled. When the closed rotary biopsy needle 7 is correctly connected to the handle, the distance between the closed rotary biopsy needle 7 and the third sensor 32 is very small. Since there is no optical path reflection distance, the sensor photocurrent is very small. When the closed rotary biopsy needle 7 is not assembled in place, the distance between the closed rotary biopsy needle 7 and the third sensor 32 increases to more than 1mm, and the third sensor 32 can receive the reflected light signal, and the photocurrent increases. At this time, the third sensor 32 and the second sensor 31 both receive the reflected signal photocurrent increase, and the control module can judge that the rotary biopsy needle is not assembled in place.
