Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a breast surgery puncture positioning device and a positioning method thereof. Background Art

[0002] Breast surgery is a branch of clinical surgery, mainly focusing on the surgical aspects of breast diseases: breast anatomy, breast infection, breast tumor pathology, breast tumor diagnosis and treatment principles, breast tumor diagnosis, various surgical procedures for breast tumors, chemotherapy, radiotherapy, and endocrine therapy. Puncture is a diagnostic and treatment technique in which a puncture needle is inserted into the body cavity to extract secretions for testing, inject gas or contrast agent into the body cavity for angiography, or inject drugs into the body cavity. The purpose of puncture is to draw blood for testing, blood transfusion, infusion, and catheter insertion for angiography. When performing breast surgery puncture, a positioning device is needed to locate the breast.

[0003] A Chinese patent with patent number ZL202010894187X discloses a breast surgical puncture positioning device. The patent inserts the puncture needle into the slot, and then passes one end of the puncture needle through the adjustment slot and inserts it into the patient's breast for treatment. However, during the process of plugging the puncture needle, the slot and the adjustment slot need to be kept connected to ensure the penetration of the puncture needle. Therefore, when performing puncture treatment on the patient, it is impossible to effectively ensure that different parts of the patient's breast are punctured. The position of the device needs to be adjusted as a whole to achieve puncture treatment of different parts of the patient's breast. The use process is relatively cumbersome, and in the process of adjusting the device, it is also necessary to ensure that the slot corresponds to the position where puncture is required. Once a deviation occurs, it will affect the treatment efficiency of the patient, greatly increasing the difficulty of the doctor's treatment and reducing the treatment efficiency.

[0004] A Chinese patent with patent number ZL202222897073.8 discloses a breast surgical puncture positioning device. Although this patent can fix the breast and locate different affected areas through air bags, it only locates the periphery of the breast and the positioning accuracy is not high.

The cover body 3 is provided with a first slide groove 31 penetrating the inner cavity thereof, and the first slide groove 31 extends from the cover bottom to the cover top of the cover body 3. Specifically, the cover body 3 is a truncated cone-shaped shell matching the shape of the breast, so as to surround the periphery of the patient's breast and cooperate with the cover body 21 to cover the entire breast of the patient;

[0065] Adjustment mechanism 4, see Figure 2 , Figure 5 and Figure 7 , which can be slidably arranged in the first slide groove 31, and includes an adjusting slide plate 41, an adjusting rotating bead 42 rotatably arranged in the middle of the adjusting slide plate 41, and a connecting needle tube 43 which can be pulled out and arranged in the adjusting rotating bead 42, wherein the connecting needle tube 43 extends to the inner cavity of the cover body 3, and a first suction cup 44 is provided at its extended end for the puncture needle to pass through for puncture treatment; specifically, the adjusting slide plate 41 can be slidably arranged in the first slide groove 31, slide up and down along the first slide groove 31, and can drive the adjusting rotating bead 42 and the connecting needle tube 43 to slide up and down so as to be moved to different affected parts of the patient.

After fine-tuning, the connecting needle tube 43 is pushed to make the first suction cup 44 adsorbed on the patient's breast, and then the puncture needle is operated for puncture treatment;

[0066] The present invention arranges the cover body 3 rotatably between the collar body 11 and the cover body 21, and at the same time, a first slide groove 31 is opened on the cover body 3, and an adjustment mechanism 4 is slidably arranged in the first slide groove 31, and the adjustment mechanism 4 includes an adjustment slide plate 41, an adjustment bead 42 rotatably arranged in the middle of the adjustment slide plate 41, and a connecting needle tube 43 that can be drawn out and arranged in the adjustment bead 42, and the connecting needle tube 43 extends to the inner cavity of the cover body 3, and a first suction cup 44 is provided at its extended end; with such an arrangement, when positioning, the connecting needle tube 43 is first carried to the area to be punctured by rotating the cover body 3, and then the adjusting slide plate 41 is slid up and down to the patient's desired treatment area, and then the adjusting bead is rotated to adjust the needle tube 43, and then the connecting needle tube 43 is adjusted to the desired treatment area. The bead 42 enables the first suction cup 44 at the extended end of the connecting needle tube 43 to be accurately positioned at the desired treatment site of the patient, and pushes the connecting needle tube 43 to make the first suction cup 44 adsorbed on the desired treatment site of the patient to achieve accurate positioning of the site to be punctured; and when the treatment of a certain affected area is completed, the adjusting slide plate 41 can be slid again to the next affected area, or the cover body 3 can be rotated again to the next area to be punctured for accurate positioning; in the present invention, the connecting needle tube 43 is driven to different affected areas of the patient by the 360-degree rotation of the cover body 3 and the up and down sliding of the adjusting slide plate 41, so that different affected areas of the patient's breast are accurately positioned in all directions for puncture treatment, and the entire operation is simple, which can greatly improve the treatment efficiency of the patient;

[0067] In addition, an inflatable cushion 12 is arranged on the inner ring wall of the ring body 11. The bulging inflatable cushion 12 can realize peripheral positioning of the bottom periphery of the patient's breast. At the same time, a top pressure-limiting structure 22 is also arranged in the cover plate, and pressure-limiting positioning is performed on the top of the breast by a pressure-limiting airbag 221; the coordinated arrangement of the inflatable cushion 12 and the pressure-limiting structure 22 enables the patient's breast to be stably clamped to prevent the patient's breast from being flattened or shaking, thereby providing a prerequisite for the precise adjustment of the connecting needle tube 43.

[0068] As a preferred embodiment, see Fig. 9 and Fig.10 The pressure-limiting structure 22 includes a plurality of pressure-limiting airbags 221 arranged on the inner surface of the cover body 21, a pressure sensor 222 installed on the outer surface of the pressure-limiting airbags 221, and a shunt air pipe 223 connected to the pressure-limiting airbags 221, and each of the shunt air pipes 223 is provided with an electric control valve 224; specifically, the plurality of pressure-limiting airbags 221 are distributed in a circular array on the inner surface of the cover body 21; and the cross-section of the airbags gradually increases from the top of the cover body 21 to the bottom thereof, so as to better fit the patient's breast; the electric control valve 224 is used to control the on-off and flow rate of the inflation of the pressure-limiting airbags 221;

[0069] It also includes a main pipe 225, one end of which passes through the cover body 21 and is connected to the branch air pipe 223, and the other end is arranged outside the cover body 21 for connecting to an air pump;

[0070] When in use, the main pipe 225 is connected to an air pump, and the corresponding electric control valve 224 is opened, the air pump inflates the pressure-limiting airbag 221, and the inflated pressure-limiting airbag 221 contacts the patient's breast. The pressure sensor 222 disposed on the outer surface of the pressure-limiting airbag 221 monitors the contact pressure, and then controls the pressure of the air pump and / or controls the flow of the electric control valve 224 based on the detected contact pressure to achieve a pressure suitable for the patient.

[0071] In this embodiment, each of the pressure-limiting airbags 221 is respectively provided with an electrically controlled valve 224. Such a configuration facilitates individual inflation of a plurality of the pressure-limiting airbags 221 distributed in an array, thereby independently limiting the pressure on the top of the breast. A pressure sensor 222 is installed on the inner surface of the pressure-limiting airbag 221. The setting of the pressure sensor 222 can detect the contact pressure in real time, thereby avoiding the problem that the pressure-limiting airbag 221 is inflated with excessive pressure, causing high pressure on the top of the breast and causing damage to the top of the breast.

[0072] As a preferred embodiment, see Figure 3 The breast surgical puncture positioning device further includes an air guide structure 5 for inflating the air cushion 12, wherein the air guide structure 5 includes an air guide tube 51, a connecting tube 52, and a connecting groove provided on the inner wall of the cover body 21;

[0074] One end of the connecting pipe 52 is clamped in the connecting groove to avoid interference with the pressure limiting airbag 221;

[0075] The connecting pipe 52 is arranged inside the cover body 3 and does not rotate with the rotation of the cover body 3; the arrangement of the air guide structure 5 and the arrangement of arranging the air guide pipe 51 on the cover body 21 facilitate the connection with the same air pump as the pressure-limiting airbag 221 and can simplify the pipeline connection.

[0076] As a preferred embodiment, see Figure 2 and Figure 5The adjusting slide 41 includes a slide body 411 and limiting slide blocks 412 arranged on both sides of the slide body 411. Correspondingly, the two groove edges of the first slide groove 31 are respectively provided with second slide grooves 32 for the limiting slide block 412 to slide up and down; specifically, the limiting slide block 412 can be integrally formed with the slide body 411, and the adjusting slide 41 damps the sliding in the first slide groove 31;

[0077] It should be noted that, since a first suction cup 44 is provided at the extended end of the connecting needle tube 43, when it is moved to a specified position, the adjustment slide 41 is adsorbed on the surface of the patient's breast by the first suction cup 44 and the current position is fixed, and the adjustment slide 41 will not slide off.

[0078] As a preferred embodiment, see Figure 6 The adjusting rotating bead 42 comprises a rotating bead body 421, a plug hole 422 for the connecting needle tube 43 to be pulled through is provided in the middle of the rotating bead body 421 along its axial direction, and a receiving groove 423 for receiving the first suction cup 44 is also provided on one side close to the inner cavity of the cover body 3;

[0079] The setting of the adjusting rotating bead 42 facilitates fine adjustment of the connecting needle tube 43 by rotating the adjusting rotating bead 42 to achieve precise positioning, and the setting of the receiving groove 423 on the rotating bead body 421 allows the first suction cup 44 to be received in the receiving groove 423 before finding the patient's treatment position, thereby avoiding interference with the patient's breast during the rotation of the cover body 3 and / or the movement of the adjusting slide plate 41;

[0080] Specifically, when accurately moving to the patient's treatment site, the connecting needle tube 43 is pushed and the first suction cup 44 is driven to move, so that the first suction cup 44 is adsorbed on the periphery of the patient's breast. At this time, the treatment site can be positioned through the adsorption of the first suction cup 44. At this time, the treatment site is located in the first suction cup 44, and then the puncture needle is inserted into the connecting needle tube 43 and the first suction cup 44, so that the puncture needle is easily inserted into the patient's treatment site, and the patient can be treated in a positioned manner, thereby improving the treatment efficiency. When not in use, the connecting needle tube 43 is pulled to accommodate a suction cup in the accommodating groove, so that the cover body 3 can be rotated when used again.

[0081] As a preferred embodiment, see Figure 3 and Figure 7 A limiting mechanism 6 for limiting the intermittent rotation of the cover body 3 is also provided between the collar body 11 and the cover body 3;

[0082] The limiting mechanism 6 includes a sliding block 61, a limiting protrusion 62 arranged on the top of the sliding block 61, and a spring 63 arranged on the bottom of the sliding block 61; in this embodiment, the limiting protrusion 62 is a hemispherical structure;

[0084] The bottom of the cover body 3 is provided with a limiting groove corresponding to the limiting hole 111 for the limiting protrusion 62 to engage with;

[0085] Through the setting of the spring 63, when in use, by rotating the cover body 3, the cover body 3 can squeeze the limiting protrusion 62, so that the spring 63 is compressed, and after rotating to the required adjustment position, the cover body 3 can be positioned under the reaction force of the spring 63; the intermittent rotating limiting mechanism 6 is set, which satisfies the rotatable connection while allowing the current position to be positioned, so as to avoid unnecessary rotation caused by accidental contact, which brings unpredictable risks to the patient's treatment.

[0086] As a preferred embodiment, a pointer is set on the periphery of the cover body 3, and a scale is engraved on the outside of the ring body 11 to facilitate accurate adjustment of the position of the cover body 3. At the same time, a pointer can also be set on the adjustment slide 41, and a scale is set on the first slide groove 31 at the corresponding position of the cover body 3 for accurate adjustment.
