Description

Technical Field

[0001] The utility model relates to a medical device for breast tissue marking, in particular to a breast tissue marker device with a visible grasping forceps. Background Art

[0002] After breast puncture or sampling, you can choose to implant breast tissue markers at the sampling site to facilitate future observation of the target tissue to check whether the target tissue has enlarged or has lesions. At present, breast tissue markers are generally implanted into the target tissue through a pusher under the guidance of imaging technology. When in use, the breast tissue marker is placed at the head end of the puncture needle tube of the pusher. After percutaneous puncture and reaching the designated position, push the trigger button on the pusher to push the marker out through the needle core in the puncture needle tube, so that the marker remains in the designated position, and then withdraw the pusher to complete the placement of the marker.

[0003] In addition, all breast tissue marker pushers on the market are for one-time use. If they are accidentally touched by humans or physically / mechanically touched during transportation, they cannot be restored after use. Clinically, markers are implanted into the target tissue through a delivery device under the guidance of imaging technology. Due to the accordion effect or the limitations of image display, the markers will shift in the breast tissue, causing the markers to deviate from the marked position (target tissue). Breast patients will be followed up after marker implantation, and the markers will be removed according to actual conditions to reduce the foreign body sensation. Because the markers are small, they need to cooperate with imaging guidance again. The removal process is complicated and can easily cause discomfort to patients. Summary of the invention

[0032] Please refer to Figures 1 to 8 , the embodiments provided by the utility model are:

[0033] A visual breast tissue marker device with grasping forceps, comprising a needle handle 1, a puncture needle 2, a trigger button 3, a push pin 4, a grasping forceps 5 and a marker 6, wherein the front end of the needle handle 1 is fixedly connected to the rear end of the puncture needle 2, the front end of the trigger button 3 is fixedly connected to the rear end of the push pin 4, the front end of the trigger button 3 is slidably arranged in the needle handle 1, the push pin 4 is slidably arranged in the puncture needle 2, the grasping forceps 5 comprises a rear fixed end 51 and an upper concave clamp head 52 and a lower convex clamp head 53 connected to the front end of the rear fixed end 51, the rear fixed end 51 is fixed At the front end of the push needle 4, the upper concave clamp head 52 and the lower convex clamp head 53 are in an open state in a natural state, and the upper concave clamp head 52 is provided with a groove 521 at the front end opposite to the lower convex clamp head 53, and the lower convex clamp head 53 is provided with a protrusion 531 opposite to the groove 521. When the upper concave clamp head 52 and the lower convex clamp head 53 are closed, the protrusion 531 is embedded in the groove 521, and the upper concave clamp head 52 and the lower convex clamp head 53 can be placed in the puncture needle 2 in the closed state, and the grasping forceps 5 are used to grasp the marker 6.

[0034] Use the puncture needle 2 to pierce the human tissue, hold the needle handle 1 and the trigger button 3 to operate, the trigger button 3 slides relative to the puncture needle 2, driving the push needle 4 and the grasping forceps 5 to slide relative to the puncture needle 2, the upper concave clamp head 52 and the lower convex clamp head 52 of the grasping forceps 5 are in an open state outside the puncture needle 2, and in a closed state inside the puncture needle 2, the groove 521 at the front end of the upper concave clamp head 52 cooperates with the protrusion 531 at the front end of the lower convex clamp head 53, which can clamp the marker 6, making it convenient to put in and take out the marker 6, and the front side of the groove 521 of the upper concave clamp head 52 naturally forms a hook structure, which is convenient for hooking the marker 6.

[0035] The process of using the above device to perform surgery is as follows: initially, the trigger button 3 is pushed forward to place the upper concave clamp head 52 and the lower convex clamp head 53 outside the puncture needle 2, and the marker 6 is placed between the upper concave clamp head 52 and the lower convex clamp head 53, and the trigger button 3 is pushed backward to close the upper concave clamp head 52 and the lower convex clamp head 53 and enter the inside of the puncture needle 2, and the marker 6 is placed. During the operation, the needle handle 1 and the puncture needle 2 are held in one hand, and the puncture needle 2 is first inserted into the human body, and the needle handle 1 and the puncture needle 2 are held in one hand. Hold the needle handle 1 and push the trigger button 3 forward with one hand to push the push needle 4 and the grasping forceps 5 forward. When the upper concave clamp head 52 and the lower convex clamp head 53 of the grasping forceps 5 move to the outside of the puncture needle 2, the upper concave clamp head 52 and the lower convex clamp head 53 open to place the marker 6 around the breast tissue. After the marker 6 is placed, push the trigger button 3 backward to close the upper concave clamp head 52 and the lower convex clamp head 53 and then enter the puncture needle 2. Next, hold the needle handle 1 to pull the puncture needle 2 out of the human body.

[0036] Specifically, the trigger button 3 and the needle handle 1 are made of plastic material, such as ABS plastic or a combination of ABS plastic and PC plastic, and the puncture needle 2, the push needle 4 and the grasping forceps 5 are mainly made of hard metal, such as a stainless steel tube or a stainless steel rod.

[0037] Furthermore, the front projection shape of the protrusion 531 is rectangular, arc-shaped or triangular, which is convenient for processing and operation. The groove 521 has the same shape as the protrusion 531 and is matched in size.

[0038] Furthermore, the marker 6 includes a marker clip 61, and the marker clip 61 includes a spiral structure, a hook structure, or a combination of a spiral structure and a hook structure. Specifically, the marker 61 is a spring spiral and a hook is integrally provided at one end thereof, and the hook can increase the probability of hooking the target tissue. Or the marker 61 is a hook-shaped structure, which increases the probability of hooking the target tissue. Or the marker 61 is a compression spring spiral structure, which facilitates clamping the target tissue by compressing the gap between the springs. Specifically, the material of the marker is titanium, Inconel625 alloy or BioDur108 stainless steel.

[0039] For further information, please refer to Figure 8 As shown, the marker 6 also includes a polymer 62, which is a soft sheet structure, and the marker clip 61 can clamp the polymer 62. Specifically, the polymer 62 is made of polyvinyl alcohol sponge, and when implanted, the polymer expands in a short time by absorbing liquid, which can reduce movement and help stop bleeding.

[0040] Furthermore, it also includes a spring 7, a silicone pad 8 and a stop pin 9. The spring 7 is installed between the trigger button 3 and the needle handle 1. The silicone pad 8 is fixed inside the needle handle 1 and is located in front of the spring 7. The stop pin 9 is fixed inside the needle handle 1 and is located behind the spring 7. The spring 7 is a compression spring. Under the action of the spring 7, when the hand is released, the trigger button 3 moves backward to the extreme position relative to the needle handle 1. The rear side of the spring 7 abuts against the stop pin 9, and the front side of the spring 7 abuts against the silicone pad 8, which has a sealing effect to prevent the intraoperative fluid from entering the trigger button 3 and the inside of the needle handle 1.

[0041] In fact, the trigger button 3 and the push pin 4 are both provided with circular through holes in their centers, and the cross-sectional shape of the gripper 5 is rectangular. Figure 6 As shown, the rear fixed end 51 of the grasping forceps 5 is embedded in the circular through hole of the push pin 4, and the liquid can pass through the gap between the two sides of the grasping forceps 5 and the circular through hole of the push pin 4. During the operation, the end of the trigger button 3 is connected to the pipe joint, and physiological saline can be injected into the human body for flushing through the circular through hole in the trigger button 3, the circular through hole in the push pin 4, and the gap between the circular through holes of the grasping forceps 5 and the push pin 4. At the same time, the internal liquid of the human body can also be sucked out of the body. The unique grasping forceps and push pin channel design, coupled with separate imaging at the needle tip, can quickly clean the wound, quickly locate and remove the marker, reduce the foreign body sensation, and quickly replenish anesthetics during the operation to reduce the patient's discomfort, which solves the doctor's operational problems and provides patients with good surgical results.

[0042] For further information, please refer to Figure 7 As shown, it also includes a protective cover 10, which is detachably clamped on the rear end outer wall of the trigger button 3 and abuts against the rear end surface of the needle handle 1. The protective cover 10 is clamped on the trigger button 3 so that the trigger button 3 cannot slide relative to the needle handle 1, thereby preventing the upper concave clamp head 52 and the lower convex clamp head 53 from opening due to accidental contact with the trigger button 3 during transportation and operation. Specifically, the protective cover is made of plastic material, such as PP plastic.

[0043] Specifically, the protective cover 10 includes an integrally connected horizontal grip portion 101 and an open arc portion 102, and the open arc portion 102 is snapped onto the rear end outer side wall of the trigger button 3. The horizontal grip portion 101 and the open arc portion 102 are both symmetrically designed, and the horizontal grip portion 101 is convenient for gripping, and the open arc portion 102 is convenient for snapping onto the trigger button 3.

[0044] Furthermore, the stop pin 9 is annular, and an annular groove 31 is provided on the circumference of the outer wall of the trigger button 3 for the stop pin 9 to slide. The protective cover 10 is clamped in the annular groove 31 and abuts against the rear end face of the needle handle 1. The existing shape of the trigger button 3 is fully utilized to make the protective cover 10. The front end of the protective cover 10 abuts against the rear end face of the needle handle 1, and the rear end abuts against the rear side end face of the annular groove 31 of the trigger button 3, which effectively prevents the trigger button 3 from sliding relative to the needle handle 1.

[0045] For further information, please refer to Figure 4 As shown, a camera 11 is also included. The front end of the puncture needle 2 is an inclined surface, and the camera 11 is fixed to the rear half of the inclined surface of the front end of the puncture needle 2. The camera can not only display the state of the target tissue in real time, but also display the specific position of the marker in real time to clearly locate the position.

[0046] For further information, please refer to Figure 4 As shown, it also includes an illumination lamp 12, which is fixed to the rear half of the front end bevel of the puncture needle 2. The setting of the illumination lamp makes the surgical field clearer, reduces the limitations of imaging of the marker due to imaging technology, such as the limitations of ultrasonic black and white images, and improves the success rate of marker marking.

[0047] Specifically, the use process of the device is as follows: during transportation, the grasping forceps 5 are placed inside the puncture needle 2, and the protective cover 10 is clamped on the trigger button 3 to prevent the grasping forceps 5 from being damaged during transportation; during preparation for surgery, if the marker 6 needs to be loaded, the protective cover 10 is removed, and the trigger button 3 is pushed forward to make the grasping forceps 5 extend outside the puncture needle 2, and the marker 6 is placed between the upper concave clamp head 52 and the lower convex clamp head 53, and then the trigger button 3 is pushed backward to make the grasping forceps 5 and the marker 6 both placed inside the puncture needle 2, and then the protective cover 10 is clamped on the trigger button 3; during surgery, the puncture needle 2 is inserted into the human tissue, so that the end of the puncture needle 2 reaches the periphery of the breast tissue, then remove the protective cover 10, push the trigger button 3, open the upper concave clamp head 52 and the lower convex clamp head 53 of the grasping forceps 5, and place the marker 6 on the breast tissue. It is best that the marker 6 can hook the breast tissue. After placement, push the trigger button 3 backward to place the grasping forceps 5 completely in the puncture needle 2; if physiological saline flushing, or adding anesthetics, or drawing out body fluids during the operation, the fluid passes through the circular through hole in the trigger button 3, the circular through hole in the push needle 4, and the gap between the circular through holes of the grasping forceps 5 and the push needle 4.

[0048] When removing the marker, percutaneous puncture is performed under the guidance of imaging. The grasping forceps 5 in the puncture needle tube are pushed out along with the push needle 4, and the upper concave forceps head 52 and the lower convex forceps head 53 are separated. Under the imaging display positioning, the camera 11 and the lighting lamp 12 at the head of the puncture needle 2 are used to further confirm that the marker 6 is found. The upper concave forceps head 52 is used to hook the hook of the marker clip 61, and the push needle 4 is pushed backward. At this time, the lower convex forceps head 53 slowly closes until the grasping forceps 5 is retracted into the puncture needle 2 tube, and the upper concave forceps head 52 and the lower convex forceps head 53 are completely closed. The concave and convex structure setting is sufficient to clamp the marker 6 firmly, and the marker 6 is quickly removed.

[0049] In summary, the visual breast tissue marker device with grasping forceps provided by the utility model has the following advantages:

[0050] 1. The design of the grasping forceps 5 facilitates the insertion and removal of the marker;

[0051] 2. The design of the protective cover 10 can prevent the device from being accidentally touched by humans or physically / mechanically touched during transportation, which may cause it to be unable to recover;

[0052] 3. The structure of the marker 6 can reduce the displacement of the marker in the breast tissue and the deviation from the marked position;

[0053] 4. Through the design of the camera 11 and the lighting lamp 12, rapid imaging and rapid positioning and removal of the marker can be achieved, thereby improving the surgical field of view, reducing the displacement of the marker 6 in the breast tissue due to the accordion effect or limitations of the image display, and improving the accuracy of the implantation of the marker 6;

[0054] 5. The circular through hole in the trigger button 3, the circular through hole in the push pin 4, and the gap design between the grasping forceps 5 and the circular through hole of the push pin 4 facilitate rapid debridement and rapid replenishment of anesthetics during surgery, thereby reducing patient discomfort.
