Description
Technical field
The utility model relates to the field of medical instrument technology, specifically a kind of anti-slip type puncture drainage guid needle.
Background technique
Due to desirability negative pressure drainage in many operations of orthopaedics, currently used is most widely band pin puncture drainage device,
The device by straight peen end is long taper, the cylindrical metal needle that diameter is 0.3cm, and tail portion connects drainage tube, by wound when operation
Deep is pierced by skin, according to drainage range after being pierced by, cuts tail portion drainage tube, and i.e. successfully merging drains removal metal needle, but
The preceding needle end is bent 30 °, and the body minister of straight is often difficult to be placed in up to 6cm or so in deeper, short wound, another is lacked
Point becomes glossy under the contamination of blood and fat to be difficult to grasp, and can not accurately penetrate target position, and guide pin rotation is held
Tissue and surgical staff are easily accidentally injured, in conjunction with two above defect, those skilled in the art provide a kind of anti-slip type puncture drainage
Guid needle.
Summary of the invention
The purpose of this utility model is to provide a kind of anti-slip type puncture drainage guid needles, to solve in above-mentioned background technique
The problem of proposition.
To achieve the above object, the utility model provides the following technical solutions:
A kind of anti-slip type puncture drainage guid needle, including guid needle, flat slot, drainage tube and cutting region, it is described to lead
The stream end that goes out of draw pin is connected with the drainage tube for playing guide functions, and the middle position of the drainage tube is provided with for connecting negative pressure
The cutting region of bottle, the guid needle go out to flow fixed at the external position at end offer convenient for the flat of needle holder or rongeur clamping
Flat grooves, the guid needle are a kind of similar semiorbicular component, and main body is cylinder, and the aperture of the guid needle is 0.3-
0.5cm, and the radius of guid needle is 5cm.
As a further solution of the present invention: the drainage tube is a kind of component of silicone rubber material.
As a further solution of the present invention: the length of the flat slot is 1cm.
Compared with prior art, the utility model has the beneficial effects that guidance needle is similar semi-circular, radius 5cm
Metal needle, compared to relatively common guidance needle, the guidance needle of the shape is more easier to carry out at merging in deeper, short wound
Reason, needle body main body are cylinder, and aperture 0.3-0.5cm, it is 1cm's that junction of the backshank apart from drainage tube, which offers length,
Flat slot, the clamping of flat slot opened up convenient for needle holder or rongeur is accurate, strong in favor of operating, and also avoids
The hand-held defect punctured at present.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 opens up structural schematic diagram for the utility model flat slot.
In figure: 1, guid needle；2, flat slot；3, drainage tube；4, region is cut.
Specific embodiment
Please refer to Fig. 1~2, in the utility model embodiment, a kind of anti-slip type puncture drainage guid needle, including guid needle 1,
The stream end that goes out in flat slot 2, drainage tube 3 and cutting region 4, guid needle 1 is connected with the drainage tube 3 for playing guide functions, drains
Pipe 3 is a kind of component of silicone rubber material, and the middle position of drainage tube 3 is provided with the cutting region 4 for connecting negative pressure bottle, leads
Draw pin 1 goes out to flow the fixed flat slot 2 offered convenient for needle holder or rongeur clamping, flat slot 2 at the external position at end
Length be 1cm, it is accurate, strong in favor of operating, also avoid the hand-held defect punctured at present, guid needle 1 is a kind of similar
Semiorbicular component, main body are cylinder, and the aperture of guid needle 1 is 0.3-0.5cm, and the radius of guid needle 1 is 5cm, is compared
The guidance needle of more common guidance needle, the shape is more easier to carry out merging processing in deeper, short wound.
It is above-described, the only preferable specific embodiment of the utility model, but the protection scope of the utility model is simultaneously
It is not limited to this, anyone skilled in the art within the technical scope disclosed by the utility model, according to this reality
It is subject to equivalent substitution or change with novel technical solution and its utility model design, should all covers the protection in the utility model
Within the scope of.
