Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a skin fixator. Background Art

[0002] An electric skin harvester is a surgical instrument that harvests skin in an electric manner. It can harvest superficial skin grafts with a thickness of 0.05 to 0.76 mm and a width of 3 to 10.2 cm and medium-thick skin grafts of various thicknesses as needed. Compared with manual skin harvesting, the harvested skin grafts are complete, with neat edges, precise thickness control, and fast speed. In the process of harvesting skin using an electric skin harvester, the skin in the area to be harvested needs to be tight and flat, and usually the assistant uses both hands to fix the skin in the area to be harvested. During the skin harvesting process, the assistant is prone to fatigue when fixing the skin with his bare hands, resulting in unstable assistance, and affecting the operation of the surgeon, which can easily cause the skin in the area to be harvested to be uneven, with different degrees of tightness and different thicknesses of the skin. Therefore, a skin fixator that can keep the skin tight and flat is needed. Utility Model Content

[0003] In order to solve the above-mentioned deficiencies in the prior art, the utility model provides a skin fixator, which helps to keep the skin of the skin-removing area tight and smooth.

[0004] In order to achieve the above technical purpose, the technical solution adopted by the utility model is:

[0005] A skin fixator comprises two symmetrically arranged fixing seats, a patch is provided at the bottom of the fixing seats, and a protective film is provided at the bottom of the patch; two adjustable support rods are connected between the two fixing seats, and the two support rods are respectively located on both sides of the fixing seats, and the two fixing seats and the two support rods form an annular area, which is the area to be skinned.

[0006] Furthermore, the support rod includes a fixed rod and a fine-tuning locker, one end of the fixed rod is connected to a fixed seat, and the other end is provided with an external thread, one end of the fine-tuning locker is rotatably connected to another fixed seat, and the end of the fine-tuning locker facing the fixed rod is provided with an internal thread, and the fixed rod is threadedly connected to the fine-tuning locker.

[0007] Furthermore, the fine-tuning locker is rotatably connected to the fixed seat through a connecting rod, and a through countersunk hole is provided in the fine-tuning locker, and an internal thread is provided on the outer periphery of the head of the countersunk hole; one end of the connecting rod passes through the countersunk hole and is threadedly connected to the fixed seat, and the other end of the connecting rod abuts the root of the countersunk hole.

[0008] Furthermore, the fixing rod is a telescopic rod.

[0009] Furthermore, an anti-slip structure is provided on the outer surface of the fine-tuning locker.

[0010] Preferably, an anti-slip groove is provided on the outer surface of the fine-tuning lock.

[0011] Another preferred embodiment is that the outer surface of the fine-tuning locker is a frosted surface.

[0012] The beneficial effects of the utility model are:

[0013] The skin fixer of the utility model forms a skin-to-be-harvested area through a fixing seat and a supporting rod, thereby avoiding the problem of requiring an assistant to help fix the skin during skin harvesting, and ensuring that the skin is sufficiently tight and has a sufficiently thick skin during the skin harvesting process.

[0014] The skin fixer of the utility model can further fine-tune the expansion of the fixing seat through the fine-tune locking device, so that the fixing seat pasted on the skin surface drives the skin to stretch, thereby maintaining a tight and flat state.

[0015] The skin fixator of the utility model has an anti-slip structure on the outer surface of the fine-adjusting locker, which makes it easier to exert force when twisting and is convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians of the art without making creative work are within the scope of protection of the present application.

[0021] A skin fixator, such as Figure 1 , Figure 2 As shown, it includes two symmetrically arranged fixing seats 1, a patch 2 is provided at the bottom of the fixing seats 1, and a protective film is provided at the bottom of the patch 2; two adjustable support rods 3 are connected between the two fixing seats 1, and the two support rods 3 are respectively located on both sides of the fixing seats 1, and the two fixing seats 1 and the two support rods 3 form an annular area 4, which is the area to be skinned.

[0022] Further, the support rod 3 includes a fixed rod 31 and a fine-tuning locker 33, one end of the fixed rod 31 is connected to the fixed seat 1, and the other end is provided with an external thread, one end of the fine-tuning locker 33 is rotatably connected to the other fixed seat 1, and the fine-tuning locker 33 is provided with an internal thread facing one end of the fixed rod 31, and the fixed rod 31 is threadedly connected with the fine-tuning locker 33, and the relative distance between the two fixed seats 1 can be adjusted by rotating the fine-tuning locker 33. Preferably, the fine-tuning locker 33 is rotatably connected to the fixed seat 1 through a connecting rod 32, and a countersunk hole is provided in the fine-tuning locker 33, and the outer periphery of the head of the countersunk hole is provided with an internal thread; one end of the connecting rod 32 passes through the countersunk hole and is threadedly connected to the fixed seat 1, and the other end of the connecting rod 32 abuts against the root of the countersunk hole. Preferably, the fixed rod is a telescopic rod, and the length of the fixed rod is adjustable, which is used to adjust the length of the annular area. Further, the outer surface of the fine-tuning locker 33 is provided with an anti-slip structure. The anti-skid structure is preferably provided with an anti-skid groove on the outer surface of the fine-tuning locker 33; another preferred embodiment is that the anti-skid structure is provided with a frosted surface on the outer surface of the fine-tuning locker 33.
