Description

Technical Field

[0001] The present invention relates to the technical field of hemostasis, and in particular to a compression hemostasis device after breast surgery. Background Art

[0002] Breast surgery is a common procedure, often used to treat benign breast tumors, breast cancer and other diseases, and can effectively prevent the occurrence and metastasis of breast cancer. However, because hospitalization is not required or the hospitalization time is relatively short, the time for dressing changes after surgery is relatively long. The breast is an important organ of women and has a rich nerve endings. Postoperative bleeding, difficulty in movement, sweating, etc. can easily cause pain and infection, affecting wound healing. In addition, due to the different locations of lesions, the bleeding points of different patients are also different. Currently, most chest compression devices apply pressure to the entire chest, making it difficult to compress and stop bleeding at the bleeding points in the chest. Summary of the Invention

[0003] In response to the shortcomings of the existing technology, the present invention proposes a compression hemostasis device after breast surgery to solve the technical problem mentioned in the above background technology that the current chest compression device is difficult to specifically compress and stop bleeding points in the chest.

[0004] In order to solve this technical problem, the technical solution adopted by the present invention is:

[0005] A compression hemostasis device for post-breast surgery, comprising a cover body, a connecting belt and a pressing mechanism;

[0006] The cover body is provided with two and is connected to form a ring structure by a connecting belt; the cover body is provided with a plurality of horizontal and vertical staggered sliding grooves, which divide the surface of the cover body into a plurality of bosses, and the sides of the bosses are provided with a plurality of limiting grooves;

[0007] The pressing mechanism includes a pressing plate, a positioning assembly and a pushing mechanism; there are multiple positioning assemblies, which are slidably connected to the slide groove, and any two adjacent positioning assemblies along the direction in which the slide groove is set can just pass through the boss, and the positioning assembly can be inserted into the limit groove and remain in the inserted state; the pressing plate is slidably connected to multiple pressing plates and can slide toward the cover body; the pushing mechanism is provided on the positioning assembly and can push the pressing plate to squeeze the cover body.

[0008] As can be seen from the above, the mask body can form a ring-shaped structure that embraces the human body through the connecting belt, thereby being fixed on the human body. Then, the pressing plate is driven to slide toward the hemostasis point through the sliding positioning component. When the pressing plate is positioned above the hemostasis point, it finds the limiting groove of the boss on the mask body, allowing the positioning component to be inserted into the limiting groove and maintain the insertion state unchanged. At this point, the positioning of the pressing plate is completed. In order to better position the pressing plate at the target position, multiple positioning components can be inserted into the limiting grooves of different bosses at the same time. After positioning is completed, the pushing component drives the pressing plate to squeeze the mask body to achieve pressurized hemostasis at the target position.

[0009] Furthermore, the positioning assembly includes a positioning tube, a wedge, a return spring, and a positioning stud; the positioning tube is slidably connected to the slide groove, the bottom end of the positioning tube is provided with a through hole along its radial direction, the wedge is slidably connected to the through hole, and is connected to the inner wall of the positioning tube via a return spring; the bottom end of the positioning stud is provided with an inclined surface, and the positioning stud is screwed to the positioning tube; when the positioning stud is rotated, the inclined surface of the positioning stud can abut the inclined surface of the wedge, and push the wedge to slide into the limiting groove. The positioning stud continuously moves downward during rotation and abuts the wedge. Since the wedge is slidably connected to the through hole of the positioning tube, the positioning stud will drive the wedge to slide away from the positioning tube and move outward. If the through hole of the positioning tube is aligned with the limiting hole of the boss of the cover body, the wedge will be inserted into the limiting hole to achieve the positioning of the pressing plate.

[0010] Furthermore, the pushing mechanism includes a connecting assembly and a pushing column. The connecting assembly is disposed on the outer wall of the positioning tube and is positioned above the pressing plate. The pushing column is threadedly connected to the connecting assembly and can drive the pressing plate to compress the cover. The arrangement of the connecting assembly allows the pushing column to be disposed independently of the pressing plate and can push the pressing plate to compress the target area as the pushing column continues to move downward.

[0011] Furthermore, a meshing assembly and a driven gear are provided; the meshing assembly includes a threaded column and a driving gear; the threaded column is provided on the top surface of the connecting assembly, and the driving gear is screwed onto the threaded column; there are multiple driven gears, and they are coaxially fixed to the positioning studs in a one-to-one correspondence; the driving gear meshes with the driven gear at the same time, and rotating the driving gear can simultaneously drive the driven gear to rotate. Rotating the driving gear and driving the driven gear simultaneously through the rotation of the driving gear allows the operator to simultaneously perform multi-point positioning of the pressing plate.

[0012] Furthermore, a circular groove is coaxially provided on the bottom surface of the driving gear, and one end of the push column is slidably connected to the groove of the driving gear, while the other end is connected to the pressing plate. By replacing the threaded connection between the push column and the connecting assembly with one end of the push column being slidably connected to the circular groove of the driving gear and the other end being connected to the pressing plate, pressure can be applied synchronously when the pressing plate is positioned.

[0013] Furthermore, the connecting assembly includes a fixing bar and a connecting plate; the fixing bar is disposed on opposite sides of the pressing plate, and both sides of the fixing bar are simultaneously connected to two adjacent positioning tubes; the connecting plate is suspended from the pressing plate and connected to the two connecting plates; the pushing column is screwed to the connecting plate and can drive the pressing plate to compress the cover body. The fixing bar allows both sides of the connecting plate to be connected to the positioning tubes on both sides of the pressing plate, thereby preventing the connecting plate from falling due to external forces.

[0027] The following embodiments of the technical solution of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0028] Please also refer to Figures 1-6 This embodiment provides a compression hemostasis device after breast surgery, including a cover body 1, a connecting belt 2 and a pressing mechanism 3.

[0029] See also Figure 1 The mask body 1 is provided with two, and is connected to form an annular structure by a connecting belt 2; the mask body 1 is provided with a plurality of horizontal and vertical staggered slide grooves, which divide the surface of the mask body 1 into a plurality of bosses 11, and the sides of the bosses 11 are provided with a plurality of limiting grooves. It should be understood that the annular structure formed by the mask bodies 1 on both sides through the connecting belt 2 can embrace the human body, so that the mask body 1 can be fixed on the patient's chest. In addition, the boss 11 formed by the horizontal and vertical staggered slide grooves is provided with a plurality of limiting grooves equidistantly on each side thereof. In this embodiment, the boss 11 is a cube, and the limiting grooves located on the same side are equidistant.

[0030] See also Figure 2-Figure 4 or Figure 6The pressing mechanism 3 includes a pressing plate 31, a positioning assembly 32, and a pushing mechanism 33. The positioning assembly 32 is provided in plurality and is slidably connected to the slide groove. Any two adjacent positioning assemblies 32 along the direction in which the slide groove is provided can just pass through the boss 11. The positioning assembly 32 can be inserted into the limiting groove and remain inserted. The pressing plate 31 is slidably connected to the plurality of pressing plates 31 and can slide toward the cover body 1. The pushing mechanism 33 is provided on the positioning assembly 32 and can push the pressing plate 31 to squeeze the cover body 1. It should be understood that the distances between adjacent positioning assemblies 32 in the same row or column are equal, and when the position of one positioning assembly 32 is aligned with the limiting groove of the boss 11, the positions of the remaining positioning assemblies 32 are also aligned with the limiting groove of the boss 11. In this case, any positioning assembly 32 can be inserted into the limiting groove. It should also be understood that the positioning assembly 32 can slide horizontally or vertically along the slide groove. It should also be understood that the pressing plate 31 is placed outside the cover 1 , and sliding the pressing plate 31 can squeeze the cover 1 . In this embodiment, four positioning assemblies 32 are provided at equal distances and are located at the four corners of the pressing plate 31 .

[0031] See also Figure 3 In other schemes, the positioning assembly 32 includes a positioning tube 321, a wedge block 322, a return spring 323 and a positioning stud 324; the positioning tube 321 is slidably connected to the slide groove, and the bottom end of the positioning tube 321 is provided with a through hole along its radial direction, the wedge block 322 is slidably connected to the through hole and is connected to the inner wall of the positioning tube 321 through the return spring 323; the bottom end of the positioning stud 324 is provided with an inclined surface, and the positioning stud 324 is screwed to the positioning tube 321; when the positioning stud 324 is rotated, the inclined surface of the positioning stud 324 can abut the inclined surface of the wedge block 322 and push the wedge block 322 to slide into the limit groove. The positioning stud 324 continuously moves downward during rotation and abuts against the wedge block 322. Since the wedge block 322 is slidably connected to the through hole of the positioning tube 321, the positioning stud 324 will drive the wedge block 322 to slide away from the positioning tube 321 and move outward. If the through hole of the positioning tube 321 is aligned with the limiting hole of the boss 11 of the cover body 1, the wedge block 322 will be inserted into the limiting hole to achieve the positioning of the pressing plate 31. It should be noted that the inclined surface of the wedge block 322 faces the center of the positioning tube 321, and multiple wedge blocks 322 can be provided. When the wedge blocks 322 are provided in multiple numbers, adjacent wedge blocks 322 form a 90° angle, and the wedge blocks 322 correspond one-to-one with the through holes of the positioning tube 321. Preferably, four wedge blocks 322 are provided, and adjacent wedge blocks 322 form a 90° angle, and the limiting holes between two adjacent bosses 11 are also relatively arranged. When the positioning stud 324 moves downward, the wedge blocks 322 slide outward, and the wedge blocks 322 at 180° to each other are respectively inserted into the limiting grooves on the two adjacent bosses 11.

[0032] See also Figure 6 In other embodiments, the pushing mechanism 33 includes a connecting assembly 331 and a pushing post 332. The connecting assembly 331 is provided on the outer wall of the positioning tube 321 and is placed above the pressing plate 31. The pushing post 332 is screwed to the connecting assembly 331 and can drive the pressing plate 31 to squeeze the cover body 1. The provision of the connecting assembly 331 allows the pushing post 332 to be provided independently of the pressing plate 31 and to push the pressing plate 31 to squeeze the target area as the pushing post 332 continuously moves downward. It should be understood that in this embodiment, the pushing post 332 is provided with a thread, which allows the pushing post 332 to continuously move downward during the rotation process, abutting and pushing the pressing plate 31 to slide toward the cover body 1, so that the pressing plate 31 can apply pressure to the hemostatic point.

[0033] See also Figure 4-Figure 6 In another embodiment, the connecting assembly 331 includes a fixing bar 3311 and a connecting plate 3312. The fixing bar 3311 is positioned oppositely on either side of the pressing plate 31. Both sides of the fixing bar 3311 are simultaneously connected to two adjacent positioning tubes 321. The connecting plate 3312 is suspended from the pressing plate 31 and connected to the two connecting plates 3312. The push column 332 is screwed onto the connecting plate 3312 and can drive the pressing plate 31 to compress the cover body 1. The fixing bar 3311 allows both sides of the connecting plate 3312 to be connected to the positioning tubes 321 on either side of the pressing plate 31, thereby preventing the connecting plate 3312 from falling due to external forces. It should be understood that the connecting plate 3312 is door frame-shaped.

[0034] The mask body 1 can form a ring-shaped structure that embraces the human body through the connecting belt 2, thereby being fixed on the human body. Then, the pressing plate 31 is driven to slide toward the hemostasis point by the sliding positioning component 32. When the pressing plate 31 is located above the hemostasis point, it finds the limiting groove of the boss 11 on the mask body 1, allowing the positioning component 32 to be inserted into the limiting groove and maintained in this inserted state. At this point, the positioning of the pressing plate 31 is completed. In order to better position the pressing plate 31 at the target position, multiple positioning components 32 can be inserted into the limiting grooves of different bosses 11 at the same time. After positioning is completed, the pushing component drives the pressing plate 31 to squeeze the mask body 1 to achieve pressurized hemostasis at the target position.

[0035] See also Figure 2-Figure 4In one embodiment, a meshing assembly 4 and a driven gear 5 are further provided. The meshing assembly 4 includes a threaded column 41 and a driving gear 42. The threaded column 41 is provided on the top surface of the connecting assembly 331, and the driving gear 42 is screwed onto the threaded column 41. There are multiple driven gears 5, and they are coaxially fixed to the positioning studs 324 in a one-to-one correspondence. The driving gear 42 simultaneously meshes with the driven gear 5, and rotating the driving gear 42 can simultaneously drive the driven gear 5 to rotate. Rotating the driving gear 42 and simultaneously driving the driven gear 5 through the rotation of the driving gear 42 allows the operator to simultaneously perform multi-point positioning of the pressing plate 31. It should be noted that the threaded column 41 is arranged on the top surface of the connecting plate 3312. At the same time, the pitch of the threaded column 41 is the same as the pitch of the positioning stud 324. Since the driving gear 42 is engaged with all the driven gears 5 at the same time, and the driven gear 5 is coaxially fixed on the positioning stud 324, when the driving gear 42 is rotated, the height difference between the driving gear 42 and the driven gear 5 remains consistent, that is, the driving gear 42 and the driven gear 5 slide down at the same time, and the sliding speed is consistent.

[0036] See also Figure 4 In another embodiment, a circular groove is coaxially provided on the bottom surface of the driving gear 42. One end of the push column 332 is slidably connected to the groove of the driving gear 42, and the other end is connected to the pressing plate 31. By changing the threaded connection between the push column 332 and the connecting assembly 331 to one in which one end of the push column 332 is slidably connected to the circular groove of the driving gear 42 and the other end is connected to the pressing plate 31, pressure can be applied synchronously when the pressing plate 31 is positioned. This embodiment changes the connection method of the push column 332 in the previous embodiment. By rotating the driving gear 42, the push column 332 no longer rotates with the rotation of the threaded column 41 after abutting the current connecting plate 3312. Instead, it moves downward as the push column 332 moves downward, thereby enabling the push column 332 to drive the pressing plate 31 to squeeze the cover body 1, thereby stopping the bleeding point.

[0037] The above-mentioned compression hemostasis device after breast surgery can perform compression hemostasis on bleeding points at different positions of the chest in a targeted manner.
