Description

Technical Field

[0001] The invention relates to the field of skin spreaders, and in particular to a skin spreader for single-person operation in breast tumor plastic surgery. Background Art

[0002] During breast tumor surgery, the tumor mass under the breast skin needs to be removed. In order to reduce the size of the wound, a suitable incision is usually made, and the skin needs to be pulled apart with a retractor before the internal tumor mass can be removed with a scalpel. During the operation, if there is no assistant or there are few assistants, the breast skin will rebound and the surgical incision field of view will be poor. In order to prevent the breast skin from rebounding and ensure the normal operation, a spreader is needed to spread and pull the breast skin.

[0003] At present, the commonly used method is to clamp the dermis with a vascular clamp and use the gravity of the vascular clamp to pull the skin open. However, this method makes the skin retraction of the incision unstable and requires constant adjustment, which significantly affects the surgical process and prolongs the operation time. In addition, the skin opening range of the vascular clamp is limited, the surgical field is not fully open, and it is inconvenient to operate. It is not convenient to stop bleeding when the surgical area bleeds, resulting in increased bleeding. At the same time, when using a vascular clamp to open the skin, the skin opening range cannot be adjusted according to actual needs, and the stability of the vascular clamp cannot be guaranteed. There are limitations in terms of poor stability and poor adaptability. Summary of the invention

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0025] like Figure 1 - Figure 7 As shown, a single-operated skin spreader for breast tumor plastic surgery includes a supporting crossbar 1, an adjusting hole 2 is opened on the supporting crossbar 1, an adjusting structure 3 is installed through the adjusting hole 2 on the supporting crossbar 1, and a connecting plate 4 is provided at the end of the adjusting structure 3, a spreading ring 5 is fixedly installed at the lower end of the connecting plate 4, a fixing structure 6 is installed at the end of the lower surface of the supporting crossbar 1, and connecting structures 7 are provided at both ends of the inner side of the supporting crossbar 1, a waist-shaped hole 8 is opened on the supporting crossbar 1, and the waist-shaped hole 8 is connected with the adjusting hole 2, the fixing structure 6 is symmetrically arranged on the supporting crossbar 1, and the connecting structure 7 is symmetrically arranged between the two supporting crossbars 1.

[0026] During a single-person operation for breast tumor plastic surgery, after the expander is disinfected and sterilized, the connecting structure 7 is adjusted according to the curvature of the patient's breast and skin, so that the fixed structure 6 at the lower end of the two support cross bars 1 is at a certain angle, and then the fixed structure 6 is attached to the skin, and the adsorption part in the fixed structure 6 is vacuumed with a syringe to ensure that the fixed structure 6 is firmly adsorbed on the skin, thereby ensuring the stable setting of the support cross bar 1. After the support cross bar 1 is set, the adjustment structure 3 is operated to move the position of the adjustment structure 3 according to the size of the wound, thereby changing the position of the connecting plate 4 and the expansion ring 5, and the adjustment structure 3 is used to cooperate with the support at the lower end of the connecting plate 4. The opening ring 5 pre-stretches the skin of the wound, and the adjustment structure 3 is continued to be operated to ensure that the stretching ring 5 has good stability after stretching the skin. Then the medical staff begins to cut, repair and reshape the breast tumor. In this process, due to the joint action of the connecting structure 7 and the fixing structure 6, the supporting cross bar 1 provides a stable supporting foundation for the adjusting structure 3, thereby ensuring the retraction and support effect on the skin, ensuring the normal progress of the operation. At the same time, the adjusting structure 3 can be operated at any time, and the size of the skin stretch can be adjusted according to needs. It is highly flexible and adaptable to use. When the operation is completed, the entire stretcher is disassembled for cleaning, sterilization and disinfection, and then stored.

[0027] Through the above implementation scheme, the adjustment structure 3 includes a movable rod 301, a retractable rod 302, an adjustment rod 303, a limit block 304, an adjustment screw hole 305, an adjustment bolt 306, a screw rod 307, a tightening block 308 and a reset assembly 309. The movable rod 301 is fixedly connected to the retractable rod 302, the adjustment rod 303 is installed in the adjustment hole 2 on the support cross bar 1, and a through hole is provided in the adjustment rod 303, the retractable rod 302 is located in the through hole, the adjustment screw hole 305 is opened on the limit block 304, and the limit block The adjusting rod 303 is installed on the adjusting rod 304, the limiting block 304 is located in the waist-shaped hole 8, the lower end of the adjusting bolt 306 is connected to the adjusting screw hole 305 on the limiting block 304, the screw rod 307 is fixed to the end of the contraction rod 302, and the end of the screw rod 307 passes through the through hole, the tightening block 308 is threadedly connected to the screw rod 307, and the reset component 309 is arranged between the movable rod 301 and the adjusting rod 303, and the reset component 309 includes a first card slot 3091, a second card slot 3092, and a card block 3093. , a reset spring 3094 and a mounting screw 3095, the first clamping slot 3091 and the second clamping slot 3092 are respectively provided on the movable rod 301 and the adjusting rod 303, and the first clamping slot 3091 and the second clamping slot 3092 are provided with connecting holes, the reset spring 3094 is arranged between the clamping blocks 3093, the two clamping blocks 3093 are respectively located in the first clamping slot 3091 and the second clamping slot 3092, the mounting screw 3095 runs through the clamping blocks 3093, and the end of the mounting screw 3095 is connected to the connecting hole. The hole is threadedly connected, and through the setting of the adjustment structure 3, the limit block 304 and the adjustment bolt 306 in the adjustment structure 3 can be used to adjust the position of the adjustment structure 3, the connecting plate 4 and the expansion ring 5 on the same supporting cross bar 1. When used in conjunction with the adjustment rod 303, the contraction rod 302, the screw 307, the tightening block 308 and other structures, the skin expansion size can be adjusted according to actual conditions, and the reset component 309 can retract and reset the pulled movable rod 301, thereby pre-expanding the skin.

[0028] When using the adjustment structure 3, after the expander is installed on the patient's skin, the position of the expander ring 5 at the lower end of the connecting plate 4 is adjusted according to the size of the wound. When adjusting, the adjusting bolt 306 connected to the adjusting screw hole 305 in the waist-shaped hole 8 is loosened, and then the adjusting rod 303 is moved. The adjusting rod 303 moves along the waist-shaped hole 8 through the limit block 304, so that the movable rod 301, the connecting plate 4 and the expander ring 5 are moved by the contraction rod 302, so that the expander ring 5 moves to a suitable position, and then the adjusting bolt 306 is used to fix it. In the initial stage, due to the action of the reset spring 3094 in the reset assembly 309, the distance between the movable rod 301 and the adjusting rod 303 is small, and there is a certain gap between the pressing block 308 and the adjusting rod 303. The expander ring 5 is moved in the direction away from the supporting cross bar 1. The movable rod 301 moves on the adjusting rod 303 through the contraction rod 302 and stretches the reset spring 3094 between the clamping blocks 3093. The reset spring 3094 is stretched and has contraction elastic potential energy. The expansion ring 5 is set to the skin wound. After the expansion ring 5 is loosened, under the action of the reset spring 3094, the movable rod 301 moves in the direction of the supporting cross bar 1, so that the skin is pre-expanded by the expansion ring 5, and then the tightening block 308 on the screw 307 is rotated, and the screw 307 and the contraction rod 302 are driven to move by the tightening block 308, so that the movable rod 301 is close to the adjusting rod 303, and then the skin is further retracted with the expansion ring 5 to ensure the retraction and support effect on the skin. When the operation is completed, the expander is removed for cleaning, disinfection and sterilization, and then stored. After long-term use, the reset spring 3094 fails and needs to be replaced. The mounting screw 3095 on the clamping block 3093 can be unscrewed with a tool, and the clamping block 3093 in the first clamping groove 3091 and the second clamping groove 3092 can be taken out and replaced. The structure is simple and the operation is convenient.

[0029] Through the above implementation scheme, the fixing structure 6 includes a fixing rod 601, a suction cup 602, a stud 603, a one-way valve 604 and a suction connector 605. The fixing rod 601 is fixed to the lower surface of the supporting cross bar 1, the suction cup 602 is fixedly connected to the stud 603, and the upper end of the stud 603 is threadedly connected to the fixing rod 601, the one-way valve 604 is fixedly connected to the suction connector 605, and the one-way valve 604 is installed on the suction cup 602, and the one-way valve 604 is communicated with the suction cup 602. The fixing structure 6 is used to fix the entire expander, and the suction cup 602 is adsorbed on the patient's skin by vacuum adsorption, which can ensure the stability of the expander and the skin stretching effect.

[0030] When the fixing structure 6 is used to adsorb and fix the entire spreader, the suction cup 602 is first rotated according to the actual situation. The suction cup 602 rotates on the fixing rod 601 with the stud 603, thereby changing the relative position of the suction cup 602 to ensure that when the suction cup 602 is adsorbed on the skin of the corresponding area, the entire spreader can better spread the skin. After the position adjustment of the suction cup 602 is completed, the suction cup 602 is adsorbed on the skin and connected to the suction connector 605 by a suction cylinder. The suction cylinder is used to perform vacuum treatment. Under the action of the one-way valve 604, the air inside the suction cup 602 flows outward in one direction, so that the inside of the suction cup 602 is in a vacuum state, thereby ensuring that the suction cup 602 can be firmly adsorbed on the skin. When the suction cup 602 is adsorbed, the entire spreader is installed, and then the skin can be retracted and supported. When the operation is completed, the suction cup 602 is pulled through the suction connector 605 at the one-way valve 604 to make the suction cup 602 fall off the skin, and then the entire spreader can be taken away.

[0031] According to the above implementation scheme, the connection structure 7 includes a first connecting rod 701, a second connecting rod 702, an adjustment frame 703, a first half gear 704, a second half gear 705, a pin 706, a threaded joint 707 and a locking nut 708. The first connecting rod 701 and the second connecting rod 702 are respectively installed on the inner sides of the two supporting cross bars 1, the first half gear 704 and the second half gear 705 are arranged inside the adjustment frame 703, and the first half gear 704 and the second half gear 705 are respectively fixedly connected to the first connecting rod 701 and the second connecting rod 702, the first half gear 704 and the second half gear 705 are meshed and connected, and the pin 706 It is installed on the first half gear 704, and the pin shaft 706 is rotatably installed on the adjustment frame 703. The threaded joint 707 is arranged on the second half gear 705, and the threaded joint 707 passes through the adjustment frame 703. The locking nut 708 is threadedly connected to the threaded joint 707, and the locking nut 708 abuts against the outer wall of the adjustment frame 703. The connection of the support cross bar 1 is carried out by the connecting structure 7. The angles of the two connecting rods can be adjusted through the first half gear 704 and the second half gear 705, so that the fixing structure 6 can better fit the patient's skin, improve the flexibility and adaptability of use, and further ensure the stability of the entire spreader.

[0032] Before using the spreader, it is necessary to adjust the relative angle of the fixed structure 6 according to the curvature of the patient's breast and skin. At this time, the locking nut 708 on the threaded joint 707 can be loosened, and the first connecting rod 701 and the second connecting rod 702 can be rotated. The first half gear 704 and the second half gear 705 at the ends of the first connecting rod 701 and the second connecting rod 702 rotate inside the adjustment frame 703, thereby adjusting the angle between the support cross bar 1 and the fixed structure 6. During this process, the first half gear 704 rotates through the pin shaft 706, and the second half gear 705 also rotates through the corresponding shaft and rotates with the threaded joint 707. After the adjustment is completed, the locking nut 708 is rotated, and the threaded joint 707 is fixed and locked using the locking nut 708, thereby locking the first half gear 704 and the second half gear 705, ensuring that the angle between the support cross bar 1 and the fixed structure 6 will not change after adjustment, thereby ensuring the stability of the entire spreader during use.
