Technical Field

[0001] The utility model relates to the field of biopsy needles, in particular to a breast rotary biopsy needle which can prevent accidental injuries. Background Art

[0002] When treating a breast tumor, a biopsy is performed on the breast tumor to analyze the composition of the breast tumor, so that subsequent treatment can be better performed. However, when performing a biopsy of a breast tumor, the doctor needs to insert the biopsy needle around the breast tumor, then rotate the biopsy needle to make the biopsy needle fit the breast tumor, and then use a suction device to suction air into the biopsy needle to suck the breast tumor into the needle hole of the biopsy needle. The breast tumor sucked into the needle hole of the biopsy needle is then cut off by a rotary cutting device, and the cut breast tumor is then removed from the body to complete a partial biopsy. The various parts of the breast tumor are then biopsied. After the biopsy is completed, the doctor pulls out the biopsy needle to complete the biopsy of the breast tumor. When the doctor rotates the biopsy needle, one side of the biopsy needle puncture entrance is squeezed, thereby enlarging the biopsy needle puncture entrance and causing accidental injury to the patient. Utility Model Content

[0003] In order to overcome the disadvantage that when the doctor rotates the biopsy needle, one side of the biopsy needle insertion port is squeezed, thereby enlarging the biopsy needle insertion port and causing accidental injury to the patient, the utility model provides a breast rotary biopsy needle that prevents accidental injury.

DETAILED DESCRIPTION

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods, but the protection scope and application scope of the present invention are not limited.

[0019] Example 1

[0020] A breast biopsy needle for preventing accidental injury, such as Figure 1-5 As shown, a rotary biopsy needle is included, and the rotary biopsy needle 1 is provided with a puncture needle 1a;

[0021] It also includes a sliding ring 2, a suction cup 3, a sliding rod 4, a connecting ring 5, a button 6 and a spring telescopic rod 7; the puncture needle 1a is slidably connected to the sliding ring 2; the sliding ring 2 is fixedly connected to the suction cup 3, by fixing the puncture entrance of the patient's breast; the rotary biopsy needle 1 is slidably connected to the sliding rod 4; the sliding rod 4 is fixedly connected to the connecting ring 5, and the connecting ring 5 is slidably connected to the sliding ring 2; the rotary biopsy needle 1 is slidably connected to the button 6, and the part of the sliding rod 4 located inside the rotary biopsy needle 1 is located in front of the button 6; the rotary biopsy needle 1 is fixedly connected to the spring telescopic rod 7, and the spring telescopic rod 7 is fixedly connected to the button 6.

[0022] A rubber layer is provided on the rear side of the button 6 so that the doctor can fix the sliding rod 4 by pressing the button 6 .

[0023] It also includes a hemostatic ring 101; the suction cup 3 is detachably connected to the hemostatic ring 101, and the hemostatic ring 101 is slidably connected to the puncture needle 1a, and the hemostatic ring 101 is made of cotton, and the blood flowing out of the puncture hole of the patient's breast is absorbed by the hemostatic ring 101.

[0024] It also includes a connecting rope 201 , and the connecting ring 5 is fixedly connected with four connecting ropes 201 , and the other end of the connecting rope 201 is fixedly connected to the edge of the suction cup 3 .

[0025] It also includes a protective film 301 , the sliding ring 2 is fixedly connected with the protective film 301 , and the protective film 301 is fixedly connected to the rotary biopsy needle 1 .

[0026] A protective cover 401 is also included, and the sliding rod 4 is hinged with the protective cover 401 .

[0027] The working steps of the above embodiment are: when a patient with breast tumor needs to undergo a breast biopsy, the doctor first determines the location of the breast tumor through an ultrasonic probe, then disinfects and injects a local anesthetic needle at the location where the rotary biopsy needle 1 needs to be inserted, and then the doctor opens the protective cover 401 and pushes the suction cup 3 and all the parts connected to it to move to the right. When the suction cup 3 moves to the left to the right of the needle hole of the puncture needle 1a, the doctor stops pushing the suction cup 3. At this time, the needle head of the puncture needle 1a is exposed to the left of the suction cup 3. If the suction cup 3 affects the doctor's observation of the needle head of the puncture needle 1a, the suction cup 3 can be pushed to the right for a distance, and then the doctor inserts the puncture needle 1a of the rotary biopsy needle 1 into the patient's breast, and the doctor holds the ultrasonic probe in his other hand to observe the situation of the puncture needle 1a in the patient's breast to prevent the puncture needle 1a from going astray. During the insertion of the puncture needle 1a, when the suction cup 3 contacts the patient's breast, The doctor then presses the button 6 to move the button 6, compressing the spring telescopic rod 7 and causing the button 6 to squeeze the sliding rod 4, so that the sliding rod 4 cannot slide in the rotary cutting biopsy needle 1. Therefore, the thrust of the doctor inserting the puncture needle 1a will act on the sliding rod 4, so that the sliding rod 4 will push the sliding ring 2, the suction cup 3 and the connecting ring 5, and then push the suction cup 3 onto the patient's breast, so that the suction cup 3 sucks the patient's breast, thereby fixing the puncture hole of the puncture needle 1a on the patient's breast, preventing the puncture hole of the puncture needle 1a from expanding when the doctor adjusts the position of the puncture needle 1a later. Then, the doctor releases the button 6, and the spring telescopic rod 7 pushes the button 6 to reset, so that the button 6 no longer squeezes the sliding rod 4, so that the sliding rod 4 can slide in the rotary cutting biopsy needle 1. Therefore, in the subsequent process of the puncture needle 1a being inserted, the patient's breast will push the sliding rod 4 into the rotary cutting biopsy needle 1, avoiding continuous pushing of the suction cup 3.

[0028] Subsequently, since it is necessary to perform a biopsy on each position of the breast tumor, the needle mouth of the puncture needle 1a can be moved to the edge of the breast tumor to perform a biopsy on the edge of the breast tumor. Then, when the needle mouth of the puncture needle 1a moves to the edge of the breast tumor, the doctor stops inserting the puncture needle 1a. Then, the doctor rotates the rotary cutting biopsy needle 1 so that the needle mouth of the puncture needle 1a fits the breast tumor. The rotary cutting biopsy needle 1 is pre-connected to an air pump. Then, the air pump connected to the rotary cutting biopsy needle 1 is controlled to inhale air into the puncture needle 1a, thereby sucking the breast tumor into the needle mouth of the puncture needle 1a. Then, the doctor presses the control switch to move the rotary cutting needle 1b to the left to the puncture needle 1a. When the rotary cutting needle 1b contacts the part of the breast tumor sucked into the needle hole of the puncture needle 1a, the rotary cutting needle 1b will cut off the part of the breast tumor. When the rotary cutting needle 1b moves to the end of the puncture needle 1a, the doctor presses the control switch again to make the rotary cutting needle 1b move to the right and reset, so that the cut part of the breast tumor is located in the rotary cutting needle 1b. When the rotary cutting needle 1b is reset, the air pump external to the rotary cutting biopsy needle 1 is controlled to blow air to the rotary cutting needle 1b, so that the cut part of the breast tumor is blown out of the rotary cutting needle 1b into the collection bin of the rotary cutting biopsy needle 1. Then the doctor moves the cut part of the breast tumor to the storage container, thereby completing a part of the biopsy.

[0029] It should be noted that when the doctor rotates the rotary biopsy needle 1, some blood will flow out from the puncture hole of the patient's breast, so that the blood will need to be cleaned later. Therefore, by placing a hemostatic ring 101 on the suction cup 3, the blood flowing out from the puncture hole of the patient's breast is absorbed by the hemostatic ring 101, thereby preventing the blood from flowing out from the puncture hole of the patient's breast, so that the blood needs to be cleaned later.

[0030] Then, the doctor rotates the rotary biopsy needle 1 so that the needle opening of the puncture needle 1a fits with other positions of the breast tumor, and then performs biopsy on other positions of the breast tumor, and repeats this process to perform biopsy on all positions of the breast tumor.

[0031] It should be noted that when the doctor rotates the rotary biopsy needle 1, since the suction cup 3 sucks the puncture hole of the puncture needle 1a on the patient's breast, the doctor's rotation of the rotary biopsy needle 1 will drive all the parts sucked by the suction cup 3 to move together, avoiding the problem that the rotation of the rotary biopsy needle 1 will expand the puncture hole of the puncture needle 1a and cause accidental injury to the patient;

[0032] When the biopsy of the breast tumor is completed, the doctor pulls out the puncture needle 1a. During the process of pulling out the puncture needle 1a, the doctor presses the button 6 again, the spring telescopic rod 7 is compressed, and the button 6 squeezes the sliding rod 4, so that the rotary biopsy needle 1 will drive the sliding rod 4 to move together, and the sliding rod 4 will drive the connecting ring 5 to move to the right. Since the connecting ring 5 is slidably connected to the sliding ring 2, the connecting ring 5 will move to the left end of the sliding ring 2 during insertion. Therefore, the sliding rod 4 will first drive the connecting ring 5 to move a distance to the right, and will not drive the sliding ring 2 and the suction cup 3 to move. Since the connecting ring 5 is connected to the side of the suction cup 3 by the connecting rope 201, the connecting ring 5 will move to the right. The suction cup 3 is connected with the edge, so that the edge of the suction cup 3 is pulled up first, and then air enters the suction cup 3 from the edge of the suction cup 3, so that the suction cup 3 no longer sucks the patient's breast, and the suction cup 3 is separated from the patient's breast by pulling up the edge of the suction cup 3, so as to avoid the problem that the puncture entrance of the puncture needle 1a may be injured when the suction cup 3 is directly connected to the patient's breast. Then, when the connecting ring 5 moves to the right end of the sliding ring 2, the connecting ring 5 drives the sliding ring 2 and the suction cup 3 to move to the right. When the puncture needle 1a is removed from the patient's breast, the puncture needle 1a is pulled out, and then the puncture entrance of the patient's breast is pressed to stop bleeding;

[0033] Then, after cleaning and disinfecting the rotary biopsy needle 1, the doctor pulls the sliding ring 2 and the suction cup 3 to the end of the puncture needle 1a. At this time, the end of the suction cup 3 is located outside the end of the puncture needle 1a, and the protective film 301 is pulled open, thereby protecting the puncture needle 1a and preventing dust from falling on the puncture needle 1a. Then, the protective cover 401 is covered on the suction cup 3 to prevent dust from entering the puncture needle 1a from the suction cup 3, thereby providing all-round protection for the puncture needle 1a, thereby replacing the protective cover of the rotary biopsy needle 1 to protect the puncture needle 1a, and solving the problem that the doctor needs to pull out the protective cover when using a traditional biopsy needle, and after placing it, the protective cover will fall to other places, so that the doctor still needs time to find the protective cover.

[0034] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
