Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a novel disposable incision retractor fixator. Background Art

[0002] During surgery, after the incision is made at the surgical site, the body tissue will contract and the incision will be closed, which makes it difficult for the surgery to proceed smoothly. In order to ensure the smooth progress of the surgery, the incision must be retracted when necessary. Traditional surgeries rely on manual retraction of the incision, which can cause damage to the incision and infect the body tissue, which is very harmful to the patient.

[0003] Regarding the incision retractor fixator disclosed in the patent publication number "CN202751416U", a first ring and a second ring are connected by a tubular elastic membrane. The first ring and the second ring are both silicone rings. During surgery, the first ring is placed inside the body and the second ring is exposed outside the body, which can effectively reduce the chance of incision infection. However, in actual use, the first ring needs to be manually inserted into the patient's body, which can easily cause wound infection and lacks disinfection and antibacterial measures. Accordingly, this application proposes a new disposable incision retractor fixator. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a novel disposable incision retractor fixator.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A new type of disposable incision retractor fixator includes a damping shaft that is bent and connected to an antibacterial cover, the damping shaft is bent and connected to a metal ring, the metal ring is provided with two rope holes, the metal ring is fixedly connected to an outer ring below, an inner ring is provided inside the outer ring and fixedly connected to the bottom of the metal ring, an elastic membrane is provided on the inner side of the inner ring, a ring piece is pasted on the inner side above the elastic membrane, a pull rope is fixedly connected to the bottom of the ring piece, and two air bag membranes are fixedly connected to the inner wall below the inner ring.

[0007] Preferably, the draw rope is fixedly connected to the other end of the ring piece, passes between the outer ring and the inner ring and exits from the rope hole.

[0008] Preferably, the bottoms of the two airbag membranes are in a breakable state and contain medical disinfectant liquid.

[0009] Preferably, the metal ring and the outer ring are both made of titanium or titanium alloy with good biocompatibility.

[0010] Preferably, the ring piece can slide against the inner wall of the inner ring.

[0011] Preferably, the elastic film is made of polyvinyl chloride (PVC) material with good plasticity.

[0012] The utility model has the following beneficial effects:

[0013] 1. By pulling the pull rope, rope hole, ring piece and other components, the pull rope is pulled to make the ring piece drive the elastic membrane to slide downward into the incision, reducing the direct contact between medical staff and the inside of the patient's incision, avoiding infection. When the ring piece slides to the airbag membrane on the inner wall of the inner ring, the airbag membrane is squeezed and broken, allowing medical disinfectant to flow out to disinfect the inside of the incision, greatly reducing the risk of secondary infection of the incision.

[0014] 2. Through the antibacterial cover and the damping shaft, when the pull rope pulls the ring piece and the elastic membrane completely into the incision, the damping shaft can be used to bend the antibacterial cover onto the metal ring to prevent external bacteria from entering, further reducing the risk of infection.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-4A new type of disposable incision retractor fixator includes a damping shaft 5 bent and connected with an antibacterial cover 4, the damping shaft 5 is bent and connected with a metal ring 2, the metal ring 2 is provided with two rope holes 8, the metal ring 2 is fixedly connected to the outer ring 7 below, the outer ring 7 is provided with an inner ring 9 fixedly connected to the bottom of the metal ring 2, the metal ring 2 and the outer ring 7 are both made of titanium and titanium alloy with good biocompatibility, which can fit well with the incision and the inside of the incision.

[0022] When the ring piece 6 slides to the airbag membrane 10 on the inner wall, the airbag membrane 10 is squeezed by the ring piece 6, and the internal disinfectant will flow out from the bottom of the airbag membrane 10 to the inside of the incision for disinfection, thereby avoiding the risk of infection to the patient.

[0023] When using this device, first place the outer ring 7 in contact with the inside of the incision, and the metal ring 2 in contact with the surface around the incision, and then start pulling the pull rope 3 above the rope hole 8 on the surface of the metal ring 2, so that the pull rope 3 drives the ring piece 6 and the elastic membrane 1 to move downward. When the ring piece 6 fits the inner wall of the inner ring 9 and slides to the airbag membrane 10, the ring piece 6 squeezes the airbag membrane 10 and makes the medical disinfectant inside the airbag membrane 10 flow out to the inside of the incision, disinfecting the inside to avoid infection inside the incision. It is also worth mentioning that when the operation on the incision needs to be suspended during the operation, the antibacterial cover 4 is closed by the damping shaft 5 to cover the metal ring 2 above the incision to prevent external bacteria from entering, further reducing the risk of infection.

[0024] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
