[0002] Diabetic foot is a disease in which blood vessels and nerves of the foot beyond the ankle joint of a diabetic patient are diseased, leading to insufficient blood supply to the foot, abnormal sensation, and symptoms of ulceration and infection, and in severe cases, it can affect muscles and bones, reaching the degree of gangrene requiring toe amputation.

[0003] For amputees, the pathological characteristics still exist, and will further ulcerate and infect as the disease worsens, accompanied by long-term bleeding. At this time, the head nurse needs to perform a hemostasis operation for a long time, which is time-consuming, and the pressing force is not stable over time, affecting the actual hemostasis effect.

[0004] There is no special toe hemostat in the prior art, and the bleeding of the amputated toe is located on the end surface of the toe, so it is difficult to bind the traditional belt-type hemostat on the sole or toe for hemostasis on the end surface of the amputated toe.

[0005] Therefore, it is necessary to develop a special hemostat for diabetic foot toe amputation, which can be fixed on the sole or toe and perform hemostasis on the end surface of the amputated toe, which has important practical significance for improving the nursing level of diabetic foot.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative labor are within the scope of protection of the present application.

[0032] It should be noted that similar reference numerals and letters indicate similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0033] In the above description of the present application, it should be noted that the terms "one side", "the other side" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the present application is usually placed, and are only for the convenience of describing the present application and simplifying the description, and therefore, cannot be understood as indicating or implying that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore, cannot be understood as limiting the present application. In addition, the terms "first", "second" and the like are only used for differentiation in description, and cannot be understood as indicating or implying relative importance.

[0034] In addition, the term "same" and the like do not mean that the components must be absolutely the same, but there can be slight differences. The term "vertical" merely means that the positional relationship between the components is more vertical than "parallel", and does not mean that the structure must be completely vertical, but can be slightly inclined.

[0035] Please refer to Figures 1-11 The embodiment provides a special hemostat for diabetic foot toe amputation, which comprises a clamping assembly 14 and a pressing assembly 15. The clamping assembly comprises a clamping sheet 1 and a pressure relief sheet 2, and the clamping sheet and the pressure relief sheet are integrally arranged. The clamping sheet and the pressure relief sheet are cold-formed into spring steel sheets, so that the clamping sheet and the pressure relief sheet have elasticity and are convenient to process. Specifically, the clamping sheet is a U-shaped elastic sheet, the U-shaped elastic sheet is provided with a clamping neck 3 protruding inward near a mouth portion, the clamping neck is adapted to the thickness of a human toe or the thickness of a human palm, the clamping sheet is fixed to the human palm or the human toe through the clamping neck, and the spring steel has good elastic recovery force and can be repeatedly used.

[0036] In the embodiment, the pressure relief sheet is a bending sheet arranged on both sides of a U-shaped opening of the U-shaped elastic sheet and extending to a U-shaped closed end. One bending sheet is arranged on each of the two sides of the U-shaped opening, and the two bending sheets are symmetrically arranged on the two sides of the U-shaped elastic sheet. When the two pressure relief sheet end portions are squeezed, an opening torque is applied to both sides of the U-shaped opening of the clamping sheet, so that the clamping sheet is in an open state and is separated from the clamping position.

[0037] In the embodiment, the pressing assembly comprises a pressing sheet 4 arranged on the inner side of the U-shaped elastic sheet and a tightening stud 5 rotatably connected with the pressing sheet through the U-shaped elastic sheet. The pressing sheet is a hard metal sheet with an arc-shaped pressing surface. After the clamping sheet is fixed to the palm, the pressing sheet is pushed to be attached to the end surface of the toe through the tightening stud. When the tightening is continued, the pressing sheet is further attached, and when the hemostatic pressure is reached, the tightening is stopped. Under the action of the thread binding force, the pressing force is maintained, so that the long-time hemostatic operation is realized, and the manpower is released.

[0038] The U-shaped clamping sheet is designed in the embodiment, the palm or the toe is clamped in the U-shaped inner cavity, then the pressing sheet is arranged in the U-shaped inner cavity, the pressing sheet is extruded to the end surface of the toe by the tightening stud for hemostatic operation, the pressure relief sheet is arranged on both sides of the clamping sheet for the clamping sheet dismounting operation, and the tightening operation space is reserved, so that the dismounting and the tightening operations are independent and do not interfere with each other.

[0039] In order to achieve the pressure relief effect or overcome the elastic constraint force of the clamping sheet, the straight-line length of the pressure relief sheet in the direction of the palm should be greater than twice the length of the clamping sheet. In this way, when the pressure relief sheet is subjected to force, the root of the clamping sheet cannot be expanded, and the clamping sheet cannot be relaxed.

[0040] As Figure 7As shown, if the straight length of the clamping plate along the foot direction is L, then the straight length of the unloading plate should be >2L.

[0041] The number of clamping components in this embodiment is not limited and can be any value from 1 to 5, depending on actual needs.

[0042] Even better, the system can be configured with 5 groups to handle extreme cases where all 5 toes have been amputated, allowing for a one-time procedure that saves time and improves efficiency. Of course, it can also be used for cases with only 1, 2, 3, or 4 toes, thus adapting to all situations and greatly meeting patient needs.

[0043] As an improvement to this embodiment, the clamping plate is provided with a stud through hole 6, and the clamping assembly also includes a nut 7 fixed outside the stud through hole. The nut is threadedly engaged with the tightening stud, and the end of the tightening stud extends into the clamping plate through the nut and connects with the clamping plate.

[0044] As an improvement to this embodiment, the clamping assembly further includes a tightening disc 8 fixed to the head of the tightening stud, and tightening teeth 9 provided on the outside of the tightening disc. The tightening disc has a diameter much larger than the stud diameter, thereby increasing the tightening torque and making tightening easier. The tightening teeth increase the coefficient of friction, preventing slippage and making tightening fast and reliable.

[0045] As an improvement to this embodiment, the tightening stud is rotatably connected to the clamping plate. Specifically, a smooth rod 10 with a diameter smaller than the outer diameter of the stud is provided at the end of the tightening stud, and an external screw 11 is provided at the end of the smooth rod. The clamping plate is provided with a smooth rod through hole 12 and a countersunk hole 13 coaxially provided with the smooth rod through hole. The smooth rod passes through the smooth rod through hole, and the external screw is connected and fixed by a connecting nut 17. The connecting nut is set in the countersunk hole to prevent it from protruding from the human body and causing excessive pressure on the human skin, thereby improving comfort.

[0046] As an improvement to this embodiment, the end of the pressure relief plate is provided with a curling pressing cylinder 16. After curling, its strength increases, and it will not undergo brittle deformation during long-term pressing operations, thereby improving its service life.

[0047] At the same time, the circular shape improves the comfort of pressing, making it easier to operate.

[0048] When multiple clamping components are used, the length of the coiled pressing cylinder can be shortened, and it does not need to be consistent with the overall clamping component length, thereby reducing the overall weight of the hemostat and improving portability. For example... Figures 9-11 As shown, cases with three, four, and five sets of clamping components are illustrated.

[0049] Finally, it is to be explained that the above embodiments are only used to illustrate the technical solutions of the present application but not to limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or equivalently replaced without departing from the purpose and scope of the present application, and all of them should be covered in the scope of the claims of the present application.
