Description
Technical field
This utility model belongs to medical instruments field, is specifically related to the flushing anti-splash device used in replacement knee in arthroplasty.
Background technology
From 20 century 70s so far, artificial knee joint replacement surgery obtains tremendous expansion.The artificial full knee joint transposing quantity that only U.S. implements every year at present reaches more than 300,000 examples.China is a big country having population more than 1,300,000,000, according to the most conservative estimation, the case suffering from knee joint osseous arthritis and rheumatoid arthritis should, more than 3,000 ten thousand, wherein have the case of significant proportion can reach satisfied reconstruction by artificial knee joint replacement.Current total knee replacement, in operation, after completing osteotomy, needs to rinse operating field with pulse flushing device, can reduce operation in patients posterior joint infection risk.But aseptic operation list mostly is cloth in current domestic operation, carries out being easy to when rinsing cause water to splash on surgical drage, and then destroy aseptic, increase postoperative infection risk.There is no the knee prosthesis designed for artificial knee joint replacement specially in the market and rinse anti-splash device, most use kidney basin in operation, simple and easy aseptic plastic bag etc., these equipment use are inconvenient, and waterproof effect is poor, to take much unnecessary trouble to assistant and operator doctor, extend operating time.So a kind of knee prosthesis of utility model rinses the common aspiration that anti-splash device is vast joint surgery doctor.
Utility model content
Technical problem to be solved in the utility model is: the deficiency existed for prior art, the flushing used in a kind of replacement knee in arthroplasty anti-splash device is provided, be beneficial to the carrying out facilitating artificial knee replacement surgery, reduce postoperative infection risk, shorten the replacement knee in arthroplasty time.
For realizing the object of this utility model, be achieved by the following technical solutions: the flushing anti-splash device used in a kind of replacement knee in arthroplasty, include interior overcoat and the external protection coating of plastic foil material, described interior overcoat is positioned at external protection coating upper center position; The curved groove shape of described interior overcoat, the two ends of interior overcoat are connected with two in order to the arc stationary pipes being clamped in thigh respectively, shank is put near knee joint position, at least two connection tubes are connected with between two arc stationary pipes, and connection tube two ends are communicated with two arc stationary pipes, described connection tube or arc stationary pipes are also connected with a gas tube; The bottom of described interior overcoat offers multiple liquid outlet along its length; Described external protection coating entirety is rectangular, the surrounding of external protection coating be connected with one end to end and be communicated with horizontal arm, four vertex positions of external protection coating are connected with four perpendicular arms longitudinally arranged, each perpendicular arm is all communicated with horizontal arm, and described perpendicular arm or horizontal arm are connected with a gas tube; At least one pipette is fixedly connected with above described external protection coating; Described four perpendicular arm bottoms are connected on a counterdie, and described counterdie is rectangular, and the length of counterdie and width are greater than length and the width of external protection coating respectively.
Preferably: the central angle of the circular arc that described arc stationary pipes surrounds is 200-250 degree.
Compared with prior art, the beneficial effects of the utility model are: be clamped on the thigh of knee joint both sides, shank by two arc stationary pipes of interior overcoat, when visual area, knee joint place being rinsed in the middle of performing the operation, liquid is stopped by interior overcoat, and flow to above external protection coating along the liquid outlet below interior overcoat, finally by the pipette be connected with negative pressure source, liquid is siphoned away.Anti-splash device structure of the present utility model is simple, and easy to use, interior external protection coating is the form be fixedly connected with, and directly launches, inflates and can use during use.Even if what described counterdie made perpendicular arm do comparatively carefully also can not produce to break away, the liquid in external protection coating is leaked.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment.
Detailed description of the invention
With reference to the accompanying drawings detailed description of the invention of the present utility model is made a detailed explanation below.
Embodiment
According to Fig. 1, the flushing anti-splash device used in a kind of replacement knee in arthroplasty described in the present embodiment, include interior overcoat 2 and the external protection coating 1 of plastic foil material, described interior overcoat is positioned at external protection coating upper center position; The curved groove shape of described interior overcoat, the two ends of interior overcoat are connected with two in order to the arc stationary pipes 21 being clamped in thigh respectively, shank is put near knee joint position, 3-5 root connection tube 22 is connected with between two arc stationary pipes, and connection tube two ends are communicated with two arc stationary pipes, described connection tube or arc stationary pipes are also connected with a gas tube 14; The bottom of described interior overcoat offers multiple liquid outlet 24 along its length; Described external protection coating entirety is rectangular, the surrounding of external protection coating be connected with one end to end and be communicated with horizontal arm 11, four vertex positions of external protection coating are connected with four perpendicular arms 12 longitudinally arranged, each perpendicular arm is all communicated with horizontal arm, described perpendicular arm is connected with a gas tube 14; At least one pipette 13 is fixedly connected with above described external protection coating.
Described four perpendicular arm bottoms are connected on a counterdie 25, and described counterdie is rectangular, and the length of counterdie and width are greater than length and the width of external protection coating respectively.Even if what described counterdie made perpendicular arm do comparatively carefully also can not produce to break away, the liquid in external protection coating is leaked.
Described arc stationary pipes bottom is fixedly connected with above external protection coating, leaves spacing between below interior overcoat and above external protection coating.Described gap enables the liquid in interior overcoat flow in external protection coating through liquid outlet is smooth and easy.
Described gas tube is connected by a three way cock with air inlet pipe, and another port of three way cock is connected with a trachea.Can inflate by the disposable pipeline by interior overcoat, external protection coating during such inflation simultaneously.Described gas tube and air inlet pipe are also connected with pressure limiting valve; Because external protection coating needs larger support force to ensure, liquid can not leak from external protection coating surrounding, and the pressure release setting value of the pressure limiting valve be connected with gas tube is higher than the pressure limiting valve be connected with air inlet pipe.
The central angle of the circular arc that described arc stationary pipes surrounds is 200-250 degree.Make being of convenient length of arc stationary pipes like this, can fixedly secure on the lower limb of patient's knee joint both sides, sufficient surgical field of view can be guaranteed again.
Be clamped on the thigh of knee joint both sides, shank by two arc stationary pipes of interior overcoat, when visual area, knee joint place being rinsed in the middle of performing the operation, liquid is stopped by interior overcoat, and flow to above external protection coating along the liquid outlet below interior overcoat, finally by the pipette be connected with negative pressure source, liquid is siphoned away.Anti-splash device structure of the present utility model is simple, and easy to use, interior external protection coating is the form be fixedly connected with, and directly launches, inflates and can use during use.
