Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of breast surgical treatment, more particularly, to a breast positioning and supporting auxiliary surgical device. BACKGROUND

[0002] Breast surgery is a common method for treating breast diseases, including breast cancer, breast hyperplasia, etc. When treating breast lumps, a puncture needle is used to puncture the lumps to obtain a specimen, and pathological diagnosis is performed on the specimen to make a final diagnosis. However, an auxiliary positioning puncture device is needed during puncture.

[0003] During breast puncture surgery, a puncture device is usually held by a person to puncture the part that needs to be punctured. During puncture, the hand may shake slightly, affecting the accuracy of puncture. In addition, the puncture needle has different insertion depths due to different puncture requirements at different positions, and the puncture angle also has certain requirements. It is difficult for medical personnel to control the puncture depth of the puncture needle when puncturing the breast position of a patient, and it is also difficult to control the puncture angle. The puncture position is not accurate, which may affect the puncture effect.

[0004] To solve the above problems, some solutions are provided in the prior art. For example, a breast department auxiliary treatment positioning puncture device is disclosed in Chinese Patent No. CN119184811B. The device adjusts the puncture depth of the puncture needle by setting a needle insertion adjusting assembly and using a stopper and a limiting tube. When the puncture needle is limited from deviating by a clamping assembly, the stopper is limited from moving by a fixed column and a positioning hole. The puncture depth is accurately controlled by using the stopper and a pressure sensor. In addition, the angle adjusting assembly is set, and a fine adjustment structure is set in the angle adjusting assembly. The puncture angle of the puncture needle can be coarsely and finely adjusted to improve the accuracy of the puncture angle of the puncture needle, thereby improving the puncture effect. However, in actual use, the breast tissue has a shaking property, and the prior art lacks positioning of the breast. Therefore, the puncture needle may deviate during puncture of the breast, which seriously affects the puncture effect. SUMMARY

[0005] To solve the problems in the prior art, the present application aims to provide a breast positioning and supporting auxiliary surgical device that can improve the puncture effect.

[0009] The clamping assembly comprises a vertical plate fixedly installed on the top wall of the mounting plate, the mounting plate is fixedly installed with a clamping plate for clamping the installation shell, and the clamping plate and the vertical plate are jointly installed with an elastic pad, the bottom wall of the mounting plate is fixedly installed with a mounting block, the end of the mounting rod away from the clamping plate is fixedly installed with a rack slidingly matched with the mounting block, the mounting block is rotatably installed with a gear meshing with the rack, the mounting block is slidingly installed with a plug rod, the end of the plug rod close to the gear is a bevel, the gear is provided with a limiting hole slidingly matched with the plug rod, and the plug rod and the mounting block are jointly installed with a first spring.

[0010] Further, the pressing disc is provided with a gas groove, the elastic pad is provided with a cavity, the cavity is inserted with an exhaust valve, the cavity is inserted with a first air pipe, the mounting plate is provided with a communication assembly, the mounting disc is provided with an annular groove, the first air pipe is communicated with the annular groove through the communication assembly, and the annular groove is inserted with a second air pipe communicated with the gas groove.

[0011] Further, the communication assembly comprises an electric push rod fixedly installed on the mounting plate, and the electric push rod is electrically connected with the electric telescopic rod, the output end of the electric push rod is provided with a communication hole communicated with the first air pipe, and the annular groove is inserted with a third air pipe communicated with the communication hole.

[0012] Further, the pressing disc is fixedly installed with a first fixed rod, the mounting disc is provided with a sliding groove matched with the first fixed rod, the mounting disc is provided with a first magnet, and the first fixed rod is embedded with a second magnet magnetically attracted to the first magnet.

[0013] Furthermore, a cavity is provided on the mounting plate, a second fixing rod is slidably installed in the cavity, a second spring is installed between the second fixing rod and the cavity, and a switch electrically connected to the electric telescopic rod is fixedly installed in the cavity, a horizontal hole is provided on the second fixing rod, a first pressure relief groove connected to the horizontal hole is provided on the annular groove, and a second pressure relief groove connected to the horizontal groove is provided on the cavity.

[0014] Furthermore, a fixing hole is provided on the connecting rod, a locking rod is fixedly mounted on the mounting rod, and one end of the locking rod away from the mounting rod is in sliding engagement with the fixing hole.

[0015] Furthermore, one end of the locking rod close to the fixing hole is tapered.

[0016] Furthermore, a silicone pad is fixedly mounted on the pressing plate.

[0017] Furthermore, two groups of the spring telescopic rods are symmetrically arranged around the puncture needle.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) This solution sets a pressing plate and presses the pressing plate on the desired puncture site. At this time, the extended spring telescopic rod drives the pressing plate to press on the patient's breast, and then the output end of the electric telescopic rod extends. During the extension of the output end of the electric telescopic rod, the puncture needle is driven to move through the mounting plate and the mounting shell, and the puncture work is performed. During the movement of the mounting plate, the spring telescopic rod is driven to move through the connecting rod and the mounting plate. Since the end of the spring telescopic rod away from the mounting plate is fixedly connected to the pressing plate, and the pressing plate is pressed on the puncture site, by pressing the puncture site, the shaking of the breast can be reduced, thereby improving the puncture effect;

[0020] (2) This solution opens a cavity. During the process of the clamping plate stretching the elastic pad, the pressure in the cavity on the elastic pad decreases. Then, after the electric telescopic rod is energized, the output end of the electric push rod extends and drives the connecting hole to connect with the first air tube. At this time, the cavity draws air into the annular groove through the first air tube, the connecting hole, and the third air tube, and reduces the pressure in the annular groove. Then, under the action of pressure, the annular groove draws air into the air groove through the second air tube. At this time, the pressing plate drives the air groove to fit with the patient's breast, so that the pressing plate and the patient's breast are adsorbed together under the action of pressure, effectively avoiding the breast flow affecting the puncture effect, and further improving the puncture effect.

[0021] (3) In this solution, the first magnet and the second magnet cooperate with each other. When the pressing plate approaches the first fixed rod through the second fixed rod, the attractive force between the first magnet and the second magnet gradually increases. At the same time, when the mounting plate moves toward the pressing plate, the compression degree of the spring telescopic rod gradually increases, that is, the pressure on the pressing plate increases. Then, the attractive force between the first magnet and the second magnet can offset the thrust applied to the pressing plate by the spring telescopic rod during the compression process, thereby balancing the pressing force of the pressing plate on the patient's breast, effectively avoiding excessive pressing force, which causes breast deformation and affects the puncture effect, and further improves the puncture effect.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0040] See also Figures 1 to 9 , a breast positioning and support auxiliary surgical device, including a support base 1 and a mounting shell 2, a mounting base 3 is rotatably mounted on the support base 1, an electric telescopic rod 4 is fixedly mounted on the mounting base 3, and a mounting plate 5 is fixedly mounted on the output end of the electric telescopic rod 4, and the mounting plate 5 is provided with a clamping component 10 for clamping the mounting shell 2, a limiting plate 6 is fixedly mounted on the top wall of the mounting plate 5, a puncture needle 7 is installed on the mounting shell 2, and a puncture groove 8 cooperating with the puncture needle 7 is opened on the limiting plate 6, and a pressing component 9 is provided on the mounting plate 5;

[0041] The pressing assembly 9 includes a connecting rod 901 symmetrically slidably mounted on the top wall of the mounting plate 5, and a mounting plate 902 is fixedly mounted on the two connecting rods 901. A spring telescopic rod 903 is fixedly mounted on the side wall of the mounting plate 902, and a pressing plate 904 is fixedly mounted on the output end of the spring telescopic rod 903.

[0042] In use, first, the mounting base 3 is fixed on the hospital bed, then the mounting shell 2 is placed on the top wall of the mounting plate 5, and the side wall of the mounting shell 2 is attached to the limiting plate 6, at this time the mounting shell 2 drives the puncture needle 7 to pass through the puncture slot 8, then the user can first move the connecting rod 901 to drive the mounting disc 902 and the pressing disc 904 to move, so as to adjust the puncture depth, and after the puncture depth adjustment is completed, the user can adjust the inclination degree of the mounting plate 5, so as to adjust the puncture angle of the puncture needle 7 (it needs to be particularly pointed out that adjusting the inclination angle of the mounting plate 5 is a relatively mature prior art, and will not be described in detail here), then the user can press the pressing disc 904 on the desired puncture site, and then the output end of the electric telescopic rod 4 is stretched, and the mounting plate 5, the mounting shell 2 drive the puncture needle 7 to move in the process of the output end of the electric telescopic rod 4 being stretched, and the puncture work is performed, and in the process of the mounting plate 5 moving, the connecting rod 901, the mounting disc 902 drive the spring telescopic rod 903 to move, since the end of the spring telescopic rod 903 away from the mounting disc 902 is fixedly connected with the pressing disc 904, and the pressing disc 904 is pressed on the puncture site, by pressing the puncture site, the shaking of the breast can be reduced, so as to improve the puncture effect.

[0043] As shown in Figure 3 , Figure 4 , Figure 5 , Figure 6 The clamping assembly 10 includes a vertical plate 101 fixedly installed on the top wall of the mounting plate 5, the mounting plate 5 is provided with a mounting block 105 fixedly installed on the bottom wall, the mounting rod 102 is fixedly installed with a clamping plate 103 for clamping the mounting shell 2, and the clamping plate 103 and the vertical plate 101 are jointly provided with an elastic pad 104, the mounting block 105 is rotatably installed with a gear 107 meshing with the rack 106, the mounting block 105 is slidably installed with an insertion rod 108, the end of the insertion rod 108 close to the gear 107 is a bevel, the gear 107 is provided with a limiting hole 109 slidably matched with the insertion rod 108, and the insertion rod 108 and the mounting block 105 are jointly provided with a first spring 1010.

[0044] The pressing disc 904 is provided with a gas groove 111, the elastic pad 104 is provided with a cavity 112, the cavity 112 is inserted with an exhaust valve 113, the cavity 112 is inserted with a first air pipe 114, and the mounting plate 5 is provided with a communication assembly 12, and the mounting disc 902 is provided with an annular groove 115, the first air pipe 114 is in communication with the annular groove 115 through the communication assembly 12, and the annular groove 115 is inserted with a second air pipe 116 in communication with the gas groove 111.

[0045] The connecting component 12 includes an electric push rod 121 fixedly mounted on the mounting plate 5, and the electric push rod 121 is electrically connected to the electric telescopic rod 4. A connecting hole 122 connected to the first air pipe 114 is opened on the output end of the electric push rod 121, and a third air pipe 123 connected to the connecting hole 122 is inserted into the annular groove 115.

[0046] By adopting the above technical solution, after the mounting shell 2 is placed on the mounting plate 5, in order to prevent the mounting shell 2 from driving the puncture needle 7 to move, the user can push the mounting rod 102 to move, and then drive the gear 107 to rotate through the rack 106 during the movement of the mounting rod 102, and in the process of the rotation of the gear 107, drive the rack 106 on the other side to move, and then drive the mounting rod 102 and the clamping plate 103 on the other side to move during the movement of the rack 106 on the other side, and then in the process of the two clamping plates 103 approaching each other, they can jointly clamp and fix the mounting shell 2, thereby effectively preventing the mounting shell 2 from driving the puncture needle 7 to move during the puncture process and affecting the puncture effect, thereby further improving the puncture effect.

[0047] In the process of the clamping plates 103 approaching each other, the elastic pad 104 is stretched, and in the process of the rack 106 driving the gear 107 to rotate, the gear 107 drives the limiting hole 109 to rotate, and then in the process of the limiting hole 109 rotating, the inclined surface of the insertion rod 108 drives the insertion rod 108 to move and stretches the first spring 1010. After the limiting hole 109 contacts the insertion rod 108 again, the first spring 1010 contracts and drives the insertion rod 108 to insert into the limiting hole 109. The cooperation between the insertion rod 108 and the limiting hole 109 makes the rack 106 move only in one direction, that is, the two clamping plates 103 can only approach each other, thereby improving the fixing effect of the mounting shell 2.

[0048] During the process of the clamping plate 103 stretching the elastic pad 104, the pressure in the cavity 112 on the elastic pad 104 decreases. Then, after the electric telescopic rod 4 is energized, the electric push rod 121 is energized, and the output end of the electric push rod 121 extends and drives the connecting hole 122 to connect with the first air pipe 114. At this time, the cavity 112 draws air from the annular groove 115 through the first air pipe 114, the connecting hole 122, and the third air pipe 123, and reduces the pressure in the annular groove 115. Then, under the action of pressure, the annular groove 115 draws air from the air groove 111 through the second air pipe 116. Since the pressing plate 904 drives the air groove 111 to fit the patient's breast at this time, the pressing plate 904 is adsorbed together with the patient's breast under the action of pressure, effectively preventing the breast shaking from affecting the puncture effect, thereby further improving the puncture effect.

[0049] like Figure 5 、 Figure 6As shown, a first fixing rod 131 is fixedly installed on the pressing plate 904, a sliding groove cooperating with the first fixing rod 131 is opened on the mounting plate 902, a first magnet 132 is provided on the mounting plate 902, and a second magnet 133 that attracts the first magnet 132 is embedded on the first fixing rod 131.

[0050] A cavity is defined on the mounting plate 902, in which a second fixing rod 134 is slidably mounted, and a second spring 135 is installed between the second fixing rod 134 and the cavity. A switch 139 electrically connected to the electric telescopic rod 4 is fixedly mounted in the cavity, a horizontal hole 136 is defined on the second fixing rod 134, a first pressure relief groove 137 communicating with the horizontal hole 136 is defined on the annular groove 115, and a second pressure relief groove 138 communicating with the horizontal groove is defined on the cavity.

[0051] By adopting the above technical solution, when the output end of the electric telescopic rod 4 extends and drives the puncture needle 7 to perform puncture through the mounting plate 5 and the mounting shell 2, the mounting plate 5 drives the mounting plate 902 to move toward the pressing plate 904 through the connecting rod 901, and during the movement of the pressing plate 904, the first fixing rod 131 gradually enters the slide groove. At the same time, during the movement of the mounting plate 902 toward the pressing plate 904, the distance between the first magnet 132 and the second magnet 133 becomes smaller, and the magnetic force between the first magnet 132 and the second magnet 133 becomes larger. When the required puncture depth is reached, the side wall of the first fixing rod 131 fits into the side wall of the slide groove. At this time, the attractive force between the first magnet 132 and the second magnet 133 is greater than the pulling force of the second spring 135 on the second fixing rod 134. Then the second fixing rod 134 moves and stretches the second spring 135, and During the movement, it gradually contacts the switch 139 and presses the switch 139, and then the output end of the electric telescopic rod 4 stops extending, so that the user does not need to manually turn off the electric telescopic rod 4. In addition, in the process of the pressing plate 904 approaching the first fixed rod 131 through the second fixed rod 134, the attraction between the first magnet 132 and the second magnet 133 gradually increases. At the same time, in the process of the mounting plate 902 moving toward the pressing plate 904, the compression degree of the spring telescopic rod 903 gradually increases, that is, the pressure on the pressing plate 904 increases, and then the attraction between the first magnet 132 and the second magnet 133 can offset the thrust applied to the pressing plate 904 during the compression of the spring telescopic rod 903, thereby balancing the pressing pressure of the pressing plate 904 on the patient's breast, effectively avoiding excessive pressing force, causing breast deformation to affect the puncture effect, and further improving the puncture effect.

[0052] When the second fixed rod 134 moves along the sliding groove and presses the switch 139, the second fixed rod 134 drives the horizontal hole 136 to communicate with the first pressure relief groove 137, at this time, the annular groove 115 inhales air from the outside through the first pressure relief groove 137, the horizontal hole 136, and the second pressure relief groove 138, thereby releasing the suction on the patient's breast, and then during the process that the output end of the electric telescopic rod 4 is retracted and drives the mounting plate 5 to move, the mounting plate 5 drives the mounting disc 902 to move through the connecting rod 901, during the process that the second fixed rod 134 moves and drives the first magnet 132 to approach the second magnet 133, the distance between the first magnet 132 and the second magnet 133 becomes smaller, and the attractive force between the first magnet 132 and the second magnet 133 becomes larger, and at this time, the attractive force between the first magnet 132 and the second magnet 133 is greater than the elastic force of the spring telescopic rod 903, then during the process that the mounting disc 902 moves, the pressing disc 904 can be driven to move together and be separated from the patient, and at the same time, the pressing disc 904 can be fixed on the mounting disc 902, thereby further improving the practicability of the device.

[0053] When puncturing, the user can first adjust the puncture angle of the puncture needle 7, and after the angle adjustment of the puncture needle 7 is completed, the user can move the pressing disc 904 away from the mounting disc 902, at this time, the distance between the first magnet 132 and the second magnet 133 becomes larger, then the second spring 135 drives the second fixed rod 134 to reset, and the second fixed rod 134 drives the first magnet 132 to move away from the second magnet 133, at this time, the elastic force of the spring telescopic rod 903 is greater than the attractive force between the first magnet 132 and the second magnet 133, then the output end of the spring telescopic rod 903 is stretched and drives the pressing disc 904 to press on the patient's breast, thereby ensuring the normal operation of the device.

[0054] When the puncture is completed, the user can control the output end of the electric telescopic rod 4 to retract and drive the mounting plate 5 to reset, then when the mounting shell 2 needs to be removed, the user pulls the plug rod 108 away from the limiting hole 109, at this time, the first spring 1010 is stretched and has a restoring tendency, after the plug rod 108 is separated from the limiting hole 109, the elastic pad 104 is retracted and drives the clamping plate 103 to reset, then as the elastic pad 104 is retracted and drives the clamping plate 103 to reset, the excess gas in the cavity 112 of the elastic pad 104 is discharged to the outside through the exhaust valve 113, and during the process that the clamping plate 103 resets, the rack 106 and the gear 107 can be reset, and after the clamping plate 103 resets, the user can release the plug rod 108, then the plug rod 108 is inserted into the limiting groove again, thereby facilitating the user to release the fixation on the mounting shell 2, thereby improving the practicability of the device.

[0055] As Figure 9As shown, a fixing hole 14 is formed on the connecting rod 901 , a locking rod 15 is fixedly mounted on the mounting rod 102 , and one end of the locking rod 15 away from the mounting rod 102 is slidably engaged with the fixing hole 14 .

[0056] One end of the locking rod 15 close to the fixing hole 14 is tapered.

[0057] By adopting the above technical solution, during the process of the clamping plate 103 moving and clamping the mounting shell 2, the mounting rod 102 drives the locking rod 15 to move, and the locking rod 15 is gradually inserted into the fixing hole 14 during the movement. By making the end of the locking rod 15 close to the fixing hole 14 conical, it is easy to insert the locking rod 15 into the fixing hole 14. After the locking rod 15 is inserted into the fixing hole 14, the connecting rod 901 can be fixed, so that the position of the mounting disk 902 can be fixed, thereby preventing the movement of the mounting disk 902 during the puncture process from affecting the puncture depth.

[0058] like Figure 2 、 Figure 6 As shown, a silicone pad 16 is fixedly mounted on the pressing plate 904 .

[0059] The spring telescopic rods 903 are symmetrically arranged in two groups around the puncture needle 7 .

[0060] By adopting the above technical solution, the pressing plate 904 can drive the silicone pad 16 to press on the patient's breast. The setting of the silicone pad 16 can improve the patient's comfort, and by symmetrically arranging two sets of spring telescopic rods 903, the pressing plate 904 can improve the uniformity of the force applied to the silicone pad 16 when the pressing plate 904 drives the silicone pad 16 to press on the patient's breast, thereby improving the pressing effect.

[0061] Instructions for use: The user can press the pressing plate 904 on the desired puncture site, and then the output end of the electric telescopic rod 4 extends. During the extension of the output end of the electric telescopic rod 4, the puncture needle 7 is driven to move through the mounting plate 5 and the mounting shell 2, and the puncture work is performed. During the movement of the mounting plate 5, the spring telescopic rod 903 is driven to move through the connecting rod 901 and the mounting plate 902. Since the end of the spring telescopic rod 903 away from the mounting plate 902 is fixedly connected to the pressing plate 904, and the pressing plate 904 is pressed on the puncture site, the shaking of the breast can be reduced. Then, before the puncture, the clamping plate 103 can clamp and fix the mounting shell 2, and the elastic pad 104 will be stretched during the movement of the clamping plate 103. At this time, the first air tube 114, the connecting component 12, and the second air tube 116 passing through the cavity 112 on the elastic pad 104 inhale air from the air groove 111, and the pressing plate 904 is adsorbed together with the patient's breast.

[0062] Then, when the required puncture depth is reached, the side wall of the first fixed rod 131 is in contact with the side wall of the slide groove. At this time, the attractive force between the first magnet 132 and the second magnet 133 is greater than the pulling force of the second spring 135 on the second fixed rod 134. Then the second fixed rod 134 moves and stretches the second spring 135, and gradually contacts and presses the switch 139 during the movement of the second fixed rod 134. Then the output end of the electric telescopic rod 4 stops extending. In the process of the mounting plate 902 moving toward the pressing plate 904, the compression degree of the spring telescopic rod 903 gradually increases, that is, the pressure on the pressing plate 904 increases. Then the attractive force between the first magnet 132 and the second magnet 133 can offset the thrust applied to the pressing plate 904 during the compression of the spring telescopic rod 903, thereby balancing the pressing pressure of the pressing plate 904 on the patient's breast.

[0063] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
