Abstract
The invention discloses a combined shoulder joint spacer die which is composed of a ball body on the upper portion, a main body on the lower portion and a metal supporting rod in the middle. The ball body and the main body are assembled to form a whole die through clamping grooves. After the metal supporting rod is placed in the die, the die can be used as the shoulder joint spacer die to make antibiotic bone cement prosthesis placeholder handles on the infected portions during shoulder joint prosthesis replacement surgeries. The combined shoulder joint spacer die is designed to conduct sterilization after washing; is disposable, thus ensuring product safety. The combined shoulder joint spacer die adopts medical silicone rubber with appropriate hardness for raw materials, thus being capable of ensuring bone cement forming accuracy.
Description
Technical field
The present invention relates to a kind of disposable combined shoulder joint prosthesis sept mould, it is applicable to the making for the antibiotic-loaded bone cement prosthesis handle of infection site in shoulder joint prosthesis replacement operation.Its feature be safe, reliable, easy and simple to handle, bulb and main body assembly flexible.After bone cement injects, be shaped perfect.Metal supporting rod can be put into increase the intensity of shaping bone cement sept.
Background technology
There is considerable time in surgical implant arthroplasty, in shoulder joint prosthesis replacement, all can run into the situation that implant site infects in advance.Combined shoulder joint sept mould is in shoulder joint displacement operation, makes the prosthese being used for replacing in advance.
Its principle is, for the shoulder joint that virus or bacillary pathological changes occur, is not suitable for direct implanting prosthetic joint.Usually after should diminishing inflammation in advance, then row implanting prosthetic joint.In antiinflammatory process, need to use support filling device, one carrys out antiinflammatory two to prevent amyotrophy.
Support in filling device selecting, usually with bone cement added with antibiotic or directly can select antibiotic-loaded bone cement, by moulding reach certain standard after, implant into body.
How can mould the shape of bone cement better faster, reach best instructions for use, be the obstacle of puzzlement orthopedist always.The requirement of modernization medical treatment to instrument can not have been adapted to by this original tool of pocket knife, scoop and pliers.Can occur a kind of easy to be easy-to-use, fast moulding, be shaped perfect instrument, becomes the hope of numerous orthopedist.
Summary of the invention
In order to meet the demand of orthopedist, make up the backward situation of present technology, the object of the invention is to provide a kind of very easy easy-to-use instrument, reaches quick, perfectly carries out moulding to bone cement.
In order to realize the object of the invention, the present invention adopts following technical scheme:
A kind of combined shoulder joint sept mould, it is made up of metal supporting rod three part of the bulb body of upper part, the main body of lower part and mid portion.Bulb body and main body can be made into a mold integral by pocket set.Namely can be used as shoulder joint sept mould after putting into metal supporting rod in a mold to use, for making antibiotic-loaded bone cement prosthese occupy-place handle to the position of infecting in shoulder joint prosthesis replacement operation.The present invention's combined shoulder joint sept Design of Dies is sterilizing after cleaning, and single use, ensures the safety of product.The present invention's combined shoulder joint sept mold materials selects medical grade silicone rubber, has suitable hardness, can ensure the accuracy that bone cement is shaped.
Advantage of the present invention and benefit:
1, structure of the present invention is simple, easily manufactures.Overall composition only has three parts, only needs metal supporting rod to insert main body, bulb body is snapped in main body and can complete assembling, and the orthopedist of first contacts does not need to learn also can skilled operation.
2, the present invention's combined shoulder joint sept die main body and bulb body have Multiple Type and size, can produce the antibiotic-loaded bone cement prosthese of multiple handle body and bulb combination to adapt to the physiological need of different patient.
3, the present invention's combined shoulder joint sept mould divides at bulb body does not have matched moulds para-position defect, and the spheroid produced is relatively more perfect.
4, the present invention's combined shoulder joint sept Design of Dies is sterilizing after cleaning, and single use, ensures the safety of product.
5, the present invention's combined shoulder joint sept mold materials selects medical grade silicone rubber, has suitable hardness, can ensure the accuracy that bone cement is shaped.
Foregoing has described the beneficial effect of art solutions of the present invention fully, below in conjunction with the drawings and specific embodiments, the present invention is further described, to make the public, summary of the invention is had a better understanding, the embodiment of detailed description of the invention is best technical scheme, and is not limitation of the present invention.

Detailed description of the invention
As shown in Figure 1, Figure 2, Figure 3, Figure 4, a kind of combined shoulder joint sept mould, it is made up of metal supporting rod 3 three part of the bulb body 1 of upper part, the main body 2 of lower part and mid portion.Bulb body and main body can combine a mold integral by draw-in groove 4.Before mould assembly, can in a mold between put into metal supporting rod 3 to strengthen the intensity of antibiotic-loaded bone cement handle 8 produced.Bulb body 1 and main body 2 have Multiple Type and size respectively, can mutually combine by wildcard between the bulb body 1 of different model and size and main body 2, mould that so just can be too many and produce the antibiotic-loaded bone cement handle of more suitable model and size.In use, assembly good combined shoulder joint sept mould, inserts the muzzle 6 of Bone cement gun 5 inlet 7 of combined shoulder joint sept mould, fills antibiotic-loaded bone cement, and after waiting bone cement to harden, strip off rubber mold can use.Shoulder joint sept mould is used for making antibiotic-loaded bone cement handle 8 to the position of infecting in shoulder joint prosthesis replacement operation and replaces prosthese occupy-place.The present invention's combined shoulder joint sept Design of Dies is sterilizing after cleaning, and single use, ensures the safety of product.The present invention's combined shoulder joint sept mold materials selects medical grade silicone rubber, has suitable hardness, can ensure the accuracy that bone cement is shaped.
