Description

Control handle and biopsy system Technical Field

[0001] The present invention relates to the technical field of biopsy systems, and in particular to a control handle and a biopsy system. Background Art

[0002] Biopsy systems are commonly used for biopsy and partial or complete removal of abnormal breast tissue. The current method of using a biopsy system is to locate abnormal tissue under ultrasound guidance and use the biopsy system for biopsy sampling or removal. The working principle of breast tissue biopsy is as follows: the control handle transmits mechanical power to the matching disposable breast excision puncture needle through gear transmission. The puncture needle converts the gear transmission into periodic reversing rotational motion and periodic reversing translational motion through a mechanical structure, which together completes the cutting action of abnormal tissue. In addition, an external device provides negative pressure to the matching disposable breast excision puncture needle through a pipeline connection. The control handle controls the matching puncture needle to open the sampling slot on the needle. Under the suction of negative pressure, the tissue to be removed is adsorbed in the sampling slot on the needle. Subsequently, the control handle controls the puncture needle to close the sampling slot. The tissue adsorbed in the sampling slot is removed by the cutting blade inside the puncture needle, forming a complete biopsy sample. The negative pressure provided by the external device then transports the excised tissue to the sample collection chamber at the tail. The above excision and then transportation process is repeated until all the abnormal tissue is excised, and the obtained sample is used for biopsy.

[0003] The control handle is a key component in the biopsy system. The control handle of the existing biopsy system has the following disadvantages:

[0004] (1) The control handle in the prior art is not waterproof. Medical staff need to clean the control handle before and after the operation. Water will flow into the control handle from the gear box, tail end, and buttons, causing short circuit or open circuit damage. Medical staff can only use dry cleaning and a small amount of alcohol to wipe it. It is impossible to ensure that the control handle is clean. If the buttons are not cleaned properly, there is a risk of contaminating the gloves when the doctor touches the buttons again when using it next time. Failure to clean the product will increase the risk of surgical infection.

[0005] (2) In the prior art, the tail connection cable of the control handle is fixed inside the housing by a wire clip. When the connection cable is pulled hard or the control handle is inverted, the gap between the upper and lower shells will be pulled and deformed to become larger. Excessive force will pull the wire clip out, resulting in a loose gap and the wiring harness inside will be pulled and broken, affecting subsequent use.

[0006] (3) The function keys on the control handle in the prior art are single and only have the basic function of cutting. Other functions need to be operated by the main unit and the trolley. The doctor cannot complete the operation with one hand and cannot adjust the knife barrel angle, the length of the inner groove of the knife barrel, the suction function, etc. When the doctor needs to operate functions other than cutting, he needs to operate back and forth between the control handle and the main unit and the trolley, or rely on another operator to assist in the operation, which is inconvenient. In addition, the upper surface of the buttons of the control handle in the prior art is made of hard plastic with low surface friction. It will slip when the doctor's rubber gloves are used, and it cannot be kept in contact. There are large gaps around the buttons, which will shake. It is also easy for water to leak into the control handle, causing circuit damage and handle failure.

[0007] (4) The control handle in the prior art does not have a screen display function or a sound prompt. It is necessary to use other supporting equipment to observe the surgical process and prompts, or to transmit information through other medical staff, which is inconvenient to operate.

DETAILED DESCRIPTION

[0060] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0061] Those skilled in the art will appreciate that, unless otherwise stated, the singular forms "a," "an," "said," and "the" used herein may also include plural forms. It should be further understood that the term "comprising" used in the specification of the present invention refers to the presence of the stated features, integers, steps, operations, elements, and / or components, but does not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0062] First embodiment

[0063] As shown in FIG1 , this embodiment provides a control handle, comprising: a handle housing 1 , a button structure 2 , a control structure 3 , a power output structure 4 , and a display structure 5 ;

[0064] The button structure 2 is arranged on the handle shell 1 and is tightly connected to the handle shell 1. The control structure 3 and the power output structure 4 are arranged inside the handle shell 1; the control structure 3 and the button structure 2 are connected by being arranged on the upper PCB board 6 inside the handle shell 1 to receive the operation instructions of the button structure 2; the control structure 3 is connected to the power output structure 4 to transmit the operation instructions to the power output structure 4; the power output structure 4 is docked with the power input structure on the matching puncture needle structure to transmit power to the puncture needle structure.

[0065] As shown in Figure 2, the handle housing 1 includes an upper cover shell 11, an upper shell 12, a lower shell 13, a locking ring 14 and a screw 15; the upper cover shell 11 is fixed to the front end of the upper shell 12, and the upper cover shell 11 is glued and fixed to the upper shell 12; the upper shell 12 is in close contact with the lower shell 13. In this embodiment, the lower shell 13 is a metal part, and the upper shell 12 is a plastic part. The connection between the upper shell 12 and the lower shell 13 has an outward gap for blocking water from the outside, and the lower shell has an inward landslide for preventing water accumulation. The water will automatically slide down the landslide to prevent water accumulation; the locking ring 14 is used to fix the tail end of the control handle. The upper shell 12 and the lower shell 13 ensure that the upper shell 12 and the lower shell 13 are in close contact and connection. The screw 15 is used to fix the upper shell 12 and the lower shell 13 at the front end of the control handle, firmly fixing the front end of the upper shell 12 and the lower shell 13. At the same time, the screw 15 leaves a gap at the contact point of the upper shell 12 and the lower shell 13. When the puncture needle structure connected on the outside and the contact surface of the control handle are too tight, it is ensured that the contact surface on the outside will not be not in close contact due to the screw 15 inside the upper shell 12 and the lower shell 13 being in too tight contact. The gap is deformed to make the puncture needle structure connected on the outside in close contact with the control handle. The present invention does not rely on snaps or other forms to fix the outer shell 13, and can make the upper shell 12 and the lower shell 13 have good sealing performance, reducing the shaking of the control handle caused by gaps such as snaps.

[0066] As shown in Figure 3, the key structure 2 includes a first key structure 21; the first key structure 21 is responsible for executing the cutting action. After pressing the first key structure 21, the command is transmitted to the power output structure 4 through the control structure 3. The transmission of the gearbox in the power output structure 4 is converted into axial linear motion and circumferential motion, which are combined to complete the cutting action. The first key structure 21 includes a key cap 211, a button 212, and a touch switch 213. The key cap 211 has a certain friction and will not slip during use. It is tightly connected to the upper cover shell 11 to ensure that water does not flow into the interior through the gap and has waterproof properties. The button 212 is arranged below the key cap 211 and above the touch switch 213 as a force transmission member for the key cap 211 and the touch switch 213, increasing the feel of the first key structure 21 and increasing the pressing area of ​​the touch switch 213, making it more comfortable to use.

[0067] As shown in Figure 4, the touch switch 213 is welded on the upper PCB board 6. During the process of pressing the button, the downward force will push down and cause the upper PCB board 6 to be concave, and the pressing effect will be worse. Therefore, the upper PCB board 6 and the upper cover shell 11 are fixed by means including fastening screws 214, gluing, and snap fasteners.

[0068] As shown in Figure 5, the key structure 2 includes a second key structure 22. This second key structure comprises a membrane key 221 and a circuit board 222. The circuit board 222 is secured to the bottom of the membrane key 221 with adhesive. The FPC cable of the circuit board 222 is pre-threaded through the groove 121 on the upper shell 12 and then embedded in the groove 121 of the upper shell 12. It is then secured to the groove 121 of the upper shell 12 with adhesive. The adhesive prevents water from entering, enhancing waterproofness. The groove 121 on the surface of the upper shell 12 solves the problem of the membrane key 221 protruding from the surface of the upper shell 12 and being difficult to locate. The FPC cable is connected to the upper PCB board 6. The membrane key 221 includes several function keys, expanding the functions of the control handle and concentrating the functions of the biopsy system on the control handle. Furthermore, the second key structure 22 is not limited to the membrane key described in this invention; it can also be a variety of different control methods, such as silicone keys, plastic keys, and touch screen controls.

[0069] Furthermore, to give a specific example, the membrane button 211 includes a plurality of combinations of function keys including a suction key, a sampling slot enlargement key, a sampling slot reduction key, a sampling slot clockwise rotation key and a sampling slot counterclockwise rotation key, a pause cutting / continue cutting key, a strong cutting mode / normal cutting mode; the suction key transmits instructions to an external device through the control structure 3 to aspirate bleeding in the surgical cavity during surgery to improve the imaging level of abnormal breast tissue under imaging; the sampling slot enlargement key and the sampling slot reduction key are used to adjust the size of the sampling slot to adapt to the tissue During surgery, some tissues are small. Using a wide-opening slot can cut into other normal tissue, causing damage. Therefore, the sampling slot size may need to be adjusted up or down to accommodate the tissue size. The clockwise and counterclockwise rotation keys of the sampling slot control the angle of the sampling slot to adjust the orientation of the tissue being sampled. During surgery, the breast may move, and abnormal tissue may move to other locations within the sampling slot. Swinging the control handle could potentially scratch and damage other normal tissue. Directly adjusting the angle of the sampling slot makes it easier to sample the abnormal tissue. The Pause / Continue Cutting key switches between continuing and pausing cutting. The Power Cutting Mode / Normal Cutting Mode switches between different cutting modes. For example, during surgery, if the surgeon needs to pause and adjust the color Doppler ultrasound angle to further observe the tissue position, they can press Pause Cutting, then confirm the position and continue the procedure by pressing Continue Cutting. For harder, dense tissue, they can switch to Power Cutting Mode for high torque and high cutting speed. For less dense tissue, they can switch to Normal Cutting Mode.

[0070] As shown in FIG6 , the power output structure 4 includes a protective cover 41, a sealing ring 42, a gear box 43, a plug 44, a screw 45, a flange 46, and a wiring assembly 47; the gear box 43 is fixed to the inside of the flange 46. In order to prevent water from entering the structure of the control handle from the bottom, the protective cover 41 serves as a waterproof structure to support both sides of the flange 46 and is fixed to the bottom of the flange 46 by the screws 45. At the same time, the protective cover 41 has a certain preset thickness to reduce the transmission of noise generated by the gear box 43 and reduce the vibration when holding the control handle, thereby avoiding the image operation experience. The protective cover 41 also serves as an isolation piece between the gear box 43 and the wiring harness, avoiding the risk of the wiring harness being caught in the gear box 43 during the connection process. Since there is a gap between the lower side of the flange 46 and the contact surface of the lower shell 13, a sealing ring 42 is provided on the lower side of the flange 46. The sealing ring 42 is provided on the contact surface between the lower side of the flange 46 and the lower shell 13. The sealing ring 42 is used to play a waterproof role when the flange 46 is squeezed downward, and to avoid the flange 46 and the lower shell 13 from being rigidly connected, thereby increasing the buffer, preventing the gear transmission from affecting the lower shell 13, and reducing the vibration. In order to prevent water from flowing out of the surface hole of the flange 46, the surface hole of the flange 46 is inserted with a plug 44. The plug 44 has a T-shaped structure. One end (large end) of the plug 44 presses against the surface hole of the flange 46 to play a waterproof role, and the other end (small end) supports the wiring assembly 47. At the same time, due to the non-metallic material characteristics of the plug 44, it plays an insulating role, preventing the flange 46 and the wiring assembly 47 from having insufficient creepage distance and causing danger. After the power output structure 4 is installed, it is fixed to the lower shell 13.

[0071] Furthermore, the display structure 5 will provide corresponding pre-operative and intra-operative prompts, accompanied by voice prompts, such as when calibration is required, calibration is complete, and cutting is required. These key operations will transmit instructions to the power output structure 4 through the control structure 3 to perform cutting, sample slot size adjustment, angle adjustment, etc. As shown in Figure 7, the display structure 5 includes a display screen cover 51 and a display screen 52. The upper cover shell 11 has a step, and the display screen cover 51 has a back adhesive or is fixed by dispensing glue. The display screen cover 51 is adhered to the step of the upper cover shell 11. The display screen 52 is fixed to the bottom of the display screen cover 51 by the back adhesive or dispensing glue of the display screen cover 51. The data transmission line of the display screen 52 is connected to the upper PCB board 6. The full contact between the display screen cover 51 and the upper cover shell 11 ensures sealing and better waterproofing. The upper surface of the display screen cover 51 is lower than the mounting surface of the upper cover shell 11 to prevent scratches on the display screen cover and prevent accidental touching of the display screen. The display screen is a color screen, which will display the steps of the surgical process. For example, before the operation, it will be prompted that the control handle is not assembled. After installing the matching disposable breast excision puncture needle, it will be prompted that calibration is required. You can press any key on the first button structure 21 or the second button structure 22 to start calibration immediately. If no key is pressed, the control handle will automatically start calibration after a short time. At this time, the display screen 52 will show that it is calibrating. After completion, it will show that it has been calibrated and remind the doctor that the operation can begin. During the operation, prompts such as cutting, suctioning, and adjusting the cutting groove will be displayed in the form of text and pictures. It can be seen that the current length and angle of the cutting groove are not only convenient for new users to operate, but also can more intuitively see the progress of the operation. There is no need to use other devices to confirm the steps of using the control handle or to transmit information during the operation through other medical staff. The display structure also has a touch control function, which allows the doctor to choose to switch the surgical information parameters he wants to display.

[0072] As shown in Figure 8, the control handle also includes a connecting cable locking structure 7; the connecting cable locking structure 7 includes a wire clip 71, a connecting cable 72, a locking ring cover 73 and a sealing ring 74; the wire clip 71 is pre-installed on the connecting cable 72 by injection molding to ensure firmness, and then the connecting cable 72 is inserted into the upper shell 12 and the lower shell 13, and the upper shell 12 and the lower shell 13 are buckled together. At this time, it is ensured that the wire clip will not be easily pulled out from the inside. The tail end surfaces of the upper shell 12 and the lower shell 13 have threads, and the locking ring 14 is rotated to the surface of the upper shell 12 and the lower shell 13 through the threads. After locking, it is ensured that the upper shell 12 and the lower shell 13 have an interference fit with the wire clip 71, and the surfaces of the upper shell 12 and the lower shell 13 are lightly inserted into the surface of the wire clip 71, so that the connecting cable 72 will not be pulled. The upper shell 12 and the lower shell 13 fix the connecting cable. After close contact, the problem of waterproofing at the tail end is solved, and the separation force between the upper shell 12 and the lower shell 13 during use is reduced. The sealing ring 74 is embedded in the surface of the locking ring 14. It does not scratch the surfaces of the upper shell 12 and lower shell 13 during the tightening process of the locking ring 14. It increases the friction of the locking ring 14 during use, creating a self-locking function that prevents it from being easily loosened. The locking ring 14 is made of a magnetic conductor and acts as a magnetic ring for the connecting cable 72. It not only serves as a decorative element for the outer surface of the connecting cable 72, but also reduces high-frequency noise in electromagnetic compatibility. The locking ring cover 73 is connected to the locking ring 14 by magnetic adsorption on the surface of the locking ring 14 or by being fastened to the inside of the locking ring 14 through its internal threads, providing a decorative cover and preventing water from flowing into the threaded gaps. In conventional control handles, when pulled forcefully, the circuit fails by first pulling the wire clip out of the shell and then breaking the internal wiring harness, or by directly breaking the internal wiring harness, resulting in a short circuit / open circuit failure. By adding the locking ring 14, the present invention requires the upper shell 12 and the lower shell 13 to break free from the locking of the locking ring 14 when being pulled. Due to the hard material of the locking ring 14, the line card 71 will only be pulled when the upper shell 12 is damaged, thereby greatly improving safety.

[0075] Furthermore, the biopsy system of this embodiment also includes an external device; the external device is used to receive instructions from the function keys of the button structure on the control handle, and perform operations including suction, sampling slot size adjustment, sampling slot clockwise rotation adjustment, sampling slot counterclockwise rotation adjustment, pause cutting / continue cutting, strong cutting mode / normal cutting mode and other combination key modes.
