[0024] The embodiments of the present disclosure aim to solve the problems that the currently clinically mainstream puncture biopsy needles are side-groove type fully automatic and semi-automatic biopsy needles. The traditional fully automatic biopsy needles can quickly cut and sample any lesion tissue properties, but cannot meet the biopsy sampling under high-risk conditions (such as lesions close to blood vessels, arteries, capsules and other tissues); the semi-automatic biopsy needles cannot meet the biopsy needle sampling of special property lesions such as hard lesions, severe fibrosis, and compactness. In view of this, the embodiments of the present disclosure propose a fully automatic multi-excitation mode biopsy needle. By setting a switchable excitation device and using a new sampling structure and a pure manual use method, not only the amount of biopsy sample tissue obtained is increased, but also the pure manual control makes the sampling process safer, and different sampling methods can be selected for different lesions, thus greatly reducing the incidence of clinical puncture biopsy emergencies or complications.
[0025] As Figures 1 to 5 shown, a fully automatic multi-excitation mode biopsy needle includes a housing 1, a fixed seat 2, a left cover 3, a right cover 4, an outer needle tube 5 and an inner needle rod 6. The fixed seat 2 is installed on the housing 1, and the housing 1 is used to protect the internal structure of the biopsy needle and is also used for holding; one end of the housing 1 is respectively installed with the left cover 3 and the right cover 4, and the left cover 3 and the right cover 4 are used to provide the excitation sliding tracks for the inner needle seat 77 and the outer needle seat 76; the outer needle tube 5 is installed at the front ends of the left cover 3 and the right cover 4, and the outer needle tube 5 is used to cut the lesion tissue; the inner needle rod 6 is installed in the outer needle tube 5, and the inner needle rod 6 is used to puncture the lesion and store the cut tissue strips. It is characterized in that it further includes a switchable excitation device 7, and the switchable excitation device 7 is installed in the housing 1, and the switchable excitation device 7 is used to perform puncture sampling in a fully automatic excitation mode or a fully automatic zero-range mode according to different lesion positions.
[0026] When the patient's lesion is in high-risk conditions (such as lesions close to blood vessels, arteries, capsules and other tissues), the lesion tissue is hard, the fibrosis degree of the lesion is high, and the lesion is compact and other adverse conditions, the traditional fully automatic biopsy needles and semi-automatic biopsy needles cannot meet the use conditions or have less sampling amount and more complications. However, by using the above-mentioned fully automatic multi-excitation mode biopsy needle, different excitation methods can be adopted according to different lesion positions, so as to achieve good puncture and sampling and reduce the probability of complications.
[0027] As Figures 1 to 5As shown, the switchable excitation device 7 includes a side excitation button 71, a zero-range excitation button 72, a tail excitation button 73, an inner needle button 74, an outer needle button 75, an outer needle seat 76, an inner needle seat 77, and a spring 78. The side excitation button 71 and the zero-range excitation button 72 are both installed on one side of the housing 1. The side firing button is used for the operator to perform puncture sampling in the full-automatic firing mode by pressing the side firing button when holding the device in a normal grip; the zero-range excitation button 72 is used for the operator to perform puncture sampling in the full-automatic zero-range mode by pressing the zero-range excitation button 72 when holding the device in a normal grip; the tail excitation button 73 is installed at the tail of the housing 1, and the tail excitation button 73 is used for the operator to perform puncture sampling in the full-automatic firing mode by pressing the side firing button when holding the device in a reverse grip; the inner needle button 74 and the outer needle button 75 are symmetrically installed on the left and right above the fixed seat 2. The inner needle button 74 is used to wind up the inner needle after the inner needle is connected to the inner needle seat 77; the outer needle button 75 is used to wind up the outer needle tube 5 after the outer needle tube 5 is connected to the outer needle seat 76; an outer needle seat 76 is installed inside the housing 1 near one side of the fixed seat 2, and the outer needle seat 76 is used to connect to the outer needle tube 5 and provide elastic force for the outer needle tube 5 during excitation; an inner needle seat 77 is installed inside the housing 1 near one side of the tail excitation button 73; the inner needle seat 77 is used to connect to the inner needle rod 6 and provide elastic force for the inner needle rod 6 during excitation; springs 78 are installed between the outer needle seat 76 and the inner needle seat 77 and between the inner needle seat 77 and the tail of the housing 1, and the springs 78 are used to provide elastic force;
[0028] By using the above switchable excitation device 7, it is possible to freely switch between the full-automatic excitation mode and the full-automatic zero-range mode during puncture; using this device not only has the ability to quickly cut and sample any lesion tissue properties, but can also perform biopsy needle sampling on special lesions such as hard lesions, severe fibrosis, and high density, and at the same time meet the full-automatic zero-range mode sampling under high-risk conditions (such as lesions close to blood vessels, arteries, capsules, etc.). It has high safety and is more suitable for various scenarios, solving the problem of which excitation sampling method of biopsy needle the doctor should choose when dealing with a cumbersome and complex lesion environment, and can freely provide the most timely and suitable biopsy plan for the patient at any time.
[0029] As Figure 2 and Figure 3As shown, a safety lock 8 is installed at the tail of the outer shell 1. The safety lock 8 is slidably installed in the outer shell 1. The safety lock 8 is used to prevent accidental firing during the puncture process and to open the safety lock 8 after the puncture is in place for full-automatic mode activation. State indicators 81 are provided at both ends of the safety lock 8. The turntable indicators are provided at both ends of the safety lock 8 to facilitate the user to quickly determine whether the safety lock 8 is open at this time. During use, first open the safety lock 8 during the puncture. At this time, the puncture work can be carried out. And when the staff accidentally touches the side activation button 71, zero-range activation button 72, and tail activation button 73, the outer needle tube 5 will not be activated to continue to twist and cut the sample. When the puncture reaches the specified position, the safety lock 8 can be opened at this time, and then the outer needle tube 5 can be activated to take a sample by pressing the specified button.
[0030] As Figure 5 shown, a silica gel pad 771 is installed on the inner needle seat 77. The silica gel pad 771 is used to provide space for winding the outer needle seat 76 and to play a buffering role.
[0031] The overall working process is as follows: After the patient's routine preparation work such as draping, disinfection, and anesthesia is completed, the doctor selects the available firing mode according to the ultrasonic image analysis, lesion properties, location, etc. However, when the location of the lesion is safe and the puncture depth conditions are met, the full-automatic activation mode can be selected. When the tissue is in a high-risk position (such as the lesion is close to tissues such as blood vessels, arteries, and capsules), the full-automatic zero-range mode can be selected. When the full-automatic activation mode is selected, by pressing the outer needle button 75 and the inner needle button 74, the biopsy needle is in a state of waiting for activation, and the puncture is carried out under imaging guidance. When reaching the edge of the lesion, press the tail activation button or the side activation button to take a sample; when the full-automatic zero-range mode is selected, a full-automatic multi-firing mode biopsy needle is punctured under imaging guidance, passes through the lesion, presses the outer needle button 75, and then presses the zero-range button to activate the outer needle tube 5 to cut and take a sample.
