Detailed Description
The utility model provides a breast tumor positioning device, and in order to make the purpose, technical scheme and effect of the utility model clearer and clearer, the utility model is further described in detail below by referring to the attached drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.
Referring to fig. 1 to 4, the present invention provides a breast tumor positioning device, which specifically includes an outer cylinder 1, a needle tube 2, a push rod 3 and an elastic inverted claw 4 extending from the lower end of the needle tube 2; the needle tube 2 is communicated with the bottom of the outer tube 1, and the push rod 3 is movably arranged in the outer tube 1 and the needle tube 2; the elastic reverse claw 4 is arranged at the lower end of the push rod 3.
It should be noted that, when the breast tumor positioning device disclosed by the present invention is not in use, the elastic inverted claw 4 is in an elastic contraction state and is positioned in the needle tube 2.
When the breast tumor resection operation is started, medical staff position and mark the breast tumor through a B ultrasonic instrument, then perform anesthesia, and make a 3-4mm incision on the skin on the surface of the breast tumor. The medical staff assisting in the field inserts the needle tube 2 of the breast tumor positioning device into the breast tissue from the incision, and leads the lower end of the needle tube 2 to reach the vicinity of the breast tumor under the guidance of the B-ultrasonic instrument. When the lower end of the needle tube 2 reaches the vicinity of the breast tumor, the medical staff assisting the field pushes the push rod 3 downwards, so that the elastic inverted claw 4 in the elastic contraction state extends out of the lower end of the needle tube 2 and is flicked. After the elastic inverted claw 4 is bounced off, the medical staff operates the breast tumor positioning device under the guidance of the B-ultrasonic apparatus, so that the breast tumor falls on the claw part of the elastic inverted claw 4 and is held by the claw part, and the positioning of the breast tumor is completed. After the breast tumor is positioned, the medical staff assisting the field holds the outer cylinder 1 to be immobile, so that the breast tumor is kept immobile in the breast tissue. Compared with the existing breast tumor excision operation, the breast tumor is positioned in the breast tissue, so that a doctor can accurately and quickly excise the breast tumor, and the operation difficulty is reduced.
In another embodiment of the present invention, a push handle 5 is provided at the upper end of the push rod 3, so that the medical staff can push the push rod 3 downwards.
In another embodiment of the present invention, the push rod 3 comprises an upper rod 301, a lower rod 302 and a sliding member 303 slidably connected to the inner wall of the outer cylinder 1; the sliding part 303 is arranged on the upper rod body 301; the lower rod body 302 is connected with the lower end of the upper rod body 301, and the outer diameter of the lower rod body 302 is smaller than the inner diameter of the needle tube 2; the elastic reverse claw 4 is arranged at the lower end of the lower rod body 302.
In this embodiment, during the pushing and pulling process of the push rod 3, the sliding member 303 snapped into the outer cylinder 1 can slide up and down relative to the outer cylinder 1, thereby ensuring the smooth movement of the push rod 3. In addition, in this embodiment, the outer diameter of the lower rod 302 is smaller than the inner diameter of the needle tube 2, so that the lower rod 302 can move downward in the needle tube 2 during the process of pushing the push rod 3 downward.
Further, in the above embodiment, the inner wall of the outer cylinder 1 is provided with the limiting member 8, and the limiting member 8 is used for limiting the upper part of the sliding member 303, so as to prevent the push rod 3 from being pulled out of the outer cylinder 1 upwards.
In another embodiment of the present invention, a holding portion 6 is disposed on the outer cylinder 1, so that the medical staff can hold the breast tumor positioning device during the operation.
In another embodiment of the utility model, the lower end of the needle cannula 2 is provided with a tip 7. The present embodiment can facilitate the rapid insertion of the needle tube 2 into the breast tissue by providing the tip 7 at the lower end of the needle tube 2.
In summary, the present invention provides a breast tumor positioning device, wherein during an operation, a medical care worker in the field pushes a push rod of the breast tumor positioning device downwards, so that an elastic inverted claw in an elastic contraction state extends from the lower end of a needle tube and is bounced; after the elastic inverted claw bounces open, the breast tumor falls on the claw part of the elastic inverted claw and is trapped, and therefore the breast tumor is positioned.
After the breast tumor is positioned, the medical care personnel with the assistance holds the outer cylinder to be immobile, so that the breast tumor is kept immobile in the breast tissue. Compared with the existing breast tumor excision operation, the breast tumor is positioned in the breast tissue, so that a doctor can accurately and quickly excise the breast tumor, and the operation difficulty is reduced.
It should be understood that the technical solutions and the inventive concepts according to the present invention may be equally replaced or changed by those skilled in the art, and all such changes or substitutions should fall within the protection scope of the appended claims.
