Abstract
The invention relates to a protective cap for the tail end of a steel needle left outside the skin. The protective cap is made from soft plastics and in a hemispherical shape and smooth in the surface; the inside of the protective cap is provided with a bayonet for clamping the tail end of the steel needle; and antibacterial sponges can be arranged around the bayonet. The whole structure is semipermeable to X rays, and has no effect on fluoroscopy and taking an X-ray picture. The protective cap can effectively prevent needle passage infection, protrusion of a steel needle, friction with the clothes, and pain caused by touch.
Description
Background of invention
Invention field
The present invention relates to a kind of medical apparatus and instruments, be specially the tail medicated cap of the draw point of protection orthopaedics use.
Background technology
At present clinically, the fracture of number of different types still fixes with the draw point of different-diameter, and after the fixing fracture of draw point, tail end is stayed the skin outside usually, is beneficial to extract in the future.Usually the time that finishing performs the operation extracts draw point, during this period, the nursing of staying skin outside draw point had certain degree of difficulty, draw point occurs through regular meeting and deviates from 4 week～12 weeks; With the medicated clothing friction; Pin site infection; Touching back produces phenomenon such as have an intense pain, and has had a strong impact on patient's quality of life, even can cause the failure of performing the operation.
Summary of the invention
A kind of tail medicated cap of main purpose design invention of the present invention is with after the fixing fracture of draw point, backshank is protected, thereby can effectively prevent pin site infection; Prevent that draw point from deviating from; With the medicated clothing friction; Prevent to touch the back and produce pain.
This material is that flexible plastic constitutes, and is dome-type, smooth surface, in have bayonet socket can block the draw point tail end, can add antibacterial sponge around the bayonet socket.The semi-transparent X ray of total does not influence perspective and claps X-ray film.
Embodiment
Medical draw point extensively should have at surgical field, orthopaedics field especially, comprise after the orthopaedics reduction of the fracture fixing, after the tendon repair, the keeping of joint position, the draw point diameter does not wait at 0.8～2.0mm, the set time is in 3 week～3 month.Usually after operation was finished, backshank was retained in skin surface, and about 3mm～10mm extracted in order to the second phase, draw point be retained in body intravital during this period of time in because backshank exceeds skin surface, through regular meeting the medicated clothing that rubs appears; Have an intense pain after the touching; Pin site infection; Even accidentally draw point is extracted and caused operative failure.And draw point tail end protective cap can block backshank and protect, smooth surface, and can not rub surrounding tissue and medicated clothing guarantee that draw point can not deviate from, and can further not go deep into body, needle track is isolated relatively, and increase antibacterial sponge and can effectively prevent pin site infection.Protective cap is made of flexible plastic, has certain resiliency, and can see through the X line, does not influence the film making check that postoperative is suffered from limb.
Embodiment 1
In the hand fracture operation, finish on the basis of open reduction, carry out fracture site with the Ke Shi draw point and fix, the draw point tail end is kept somewhere in skin surface the about 0.5mm of backshank length.Block the draw point tail end with draw point tail end protective cap bayonet socket, and guarantee protective cap periphery and skin attachement.
Embodiment 2
In children's's metaphysis fracture operation, finish on the basis of open reduction, carry out fracture site with Ke Shi draw point or Si Shi draw point and fix, the draw point tail end is kept somewhere in skin surface the about 0.5mm of backshank length.Block the draw point tail end with draw point tail end protective cap bayonet socket, and guarantee protective cap periphery and skin attachement.
Embodiment 3
In extremities joint and in the fracture around joint operation, finish on the basis of open reduction, carry out fracture site with the Ke Shi draw point and fix, the draw point tail end is being kept somewhere in skin surface the about 0.5mm of backshank length.Block the draw point tail end with draw point tail end protective cap bayonet socket, and guarantee protective cap periphery and skin attachement.
Embodiment 4
In extensor digitorum muscle of hand tendon fulcrum fracture prosthesis, finish on the basis of tendon repair, carry out the distal interphalangeal joint back of the body with the Ke Shi draw point and stretch the fixing of position, the draw point tail end is kept somewhere in skin surface the about 0.5mm of backshank length.Block the draw point tail end with draw point tail end protective cap bayonet socket, and guarantee protective cap periphery and skin attachement.
Embodiment 5
In bone surgery, draw point to be kept somewhere in body, the draw point tail end is kept somewhere when skin surface, and backshank length is kept about 0.5mm.Block the draw point tail end with draw point tail end protective cap bayonet socket, and guarantee protective cap periphery and skin attachement.
