Problems solved by technology

[0004] However, the current dilators all expand the skin that needs to be expanded at the same time. This method requires a large expansion force. If the control is not good, it is easy to strain the skin and the underlying flesh tissue.

Embodiment Construction

[0042] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0043] Such as Figure 1-7 As shown, a skin dilator for plastic surgery includes a main capsule 1 with a circular cross section and at least one annular auxiliary capsule 2 coaxially sleeved outside the main capsule 1, and the main capsule 1 is provided with a catheter 4 , one end of the conduit 4 communicates with the inside of the main capsule 1. When there is one annular secondary capsule 2, the main capsule 1 communicates with the annular secondary capsule 2 through a flow-limiting connecting tube 3. When there are multiple annular secondary capsules 2, The diameters of multiple annular auxili...

Abstract

The invention relates to the field of medical instruments, and particularly relates to a skin expander for plastic surgery. The skin expander comprises a main bag and at least one annular auxiliary bag, wherein the cross section of the main bag is circular; a catheter used for injecting normal saline is arranged on the main bag; one end of the catheter communicates with the interior of the main bag; the annular auxiliary bags are coaxially arranged on the outer side of the main bag in a sleeving mode; when one annular auxiliary bag is arranged, the main bag communicates with the annular auxiliary bags through flow limiting connecting pipes; when multiple annular auxiliary bags are arranged, the diameters of the annular auxiliary bags are different; the large annular auxiliary bag is coaxially arranged on the outer side of the small annular auxiliary bag in a sleeving mode; the main bag communicates with the adjacent annular auxiliary bag through one flow limiting connecting pipe; everytwo adjacent annular auxiliary bags communicate through one flow limiting connecting pipe; and the flow limiting connecting pipes are connected when hydraulic pressure reaches a certain value. The expander can expand skin step by step.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a skin dilator for plastic surgery and a flow-limiting connecting tube. Background technique [0002] The skin expander is a relatively advanced treatment method used in plastic surgery. Its principle is to implant the skin and soft tissue expander under the normal skin and soft tissue near the lesion, and increase the capacity of the expander by intermittently injecting liquid into the expansion sac to make it Pressure on the superficial skin soft tissue. Through the local effect of the expansion mechanism, the division and proliferation of tissue and epidermal cells and the expansion of the intercellular space are enlarged, thereby increasing the skin area. After removing the expansion sac, the newly increased skin soft tissue can be used for tissue repair and organ reconstruction. [0003] The skin expansion operation usually lasts for 6-8 months, and normal saline is injected ...
