Description

[Detailed description of the invention] Surgical products TECHNICAL FIELD This invention relates to surgical supplies used in artificial joints.

Shoulder replacement, especially in cases of osteoarthritis and avascular death. +m+a+) has a non-zero good outcome for patients with healthy soft tissue around the shoulder. It has been shown that it brings about results. However, patients with significant soft tissue defects , especially in patients with rotational disc defects (e.g. in cases of rheumatoid arthritis). is unrestrained shoulder replacement i+ncoc++ri+mouth cd+homouth1d++repl zeem+n+) is inappropriate (tti+mouth&Lllzce (1,986 ) 3rd IC3S). Kc+tel restraint shoulder replacement may be used in these situations. There is. However, Sweden's Wa l l in the 3rd tcss was mouth + t. In a series of 24 gastric replacements using a K+1tel restraint shoulder, a report by +in , Regarding glenoid detachment (glenOid 1ooi+aing) in the 2nd to 4th year period. Then a serious @Nen showed Rukoto.

Therefore, there is a need to find ways to stabilize the unrestrained shoulder when the rotational plate is defective. There is.

a natural or artificial socket into which the head of said head component fits; In contrast to the knee joint prosthesis, the applicant has ) tibial component or (in the case of a shoulder joint prosthesis) humeral component We will call this component the “head” component.

This head component (wrist arthroplasty!hem rlh+oplz+17]) consists of a head part and a shaft part, which in use extends into the tibia or humerus. Ru.

In one aspect of the invention, this is the head of a knee or shoulder prosthesis. means for engaging the head component of the head component; containing at least a portion of the head component and generally spaced from the detail of the head component. and suitable means for extending beyond said head in that direction. wherein at least a portion of said containment means is suitable for intra-articular use. often adapted to allow soft tissue ingrowth from around the joint .

This item may be used regardless of whether the joint socket is replaced by an artificial socket. Available for use.

The surgical article is generally tubular and houses the head of the head component. It will have a relatively wide open end and will accept the axis of its head component. Preferably, the head has a relatively narrow open end that does not accept a languid . The open narrow end of the article thus forms said engagement means of the article; The wide open end forms at least a portion of the head receiving means. This narrow end is the tube over its entire length or (more preferably) over a portion of its length; It may be produced by attaching a taber to.

From a manufacturing point of view, it is advantageous for this narrow end to be on-axis; From an objective point of view, it may be advantageous for this narrow end to be offset from the narrow end. both Both embodiments are included within the scope of the present invention.

Preferably, the surgical article is made from a surgically inert flexible fabric; generally either a tube or flat pieces sewn together to form a tube woven or knitted as a single component such as. This narrow end is used in the knitting process. It may be formed in a cutting and stitching process. ’ D+++o*’ (1)l Foct trademark) and ‘TeB1+ne’ (ICi Trademark) is a suitable polyester fiber. This material is a combination of this material and the convolute plate. May be coated or impregnated with gelatin or another biodegradable material to aid in integration. is possible.

The openness of the mesh allows for tissue ingrowth and provides the necessary structural integrity. Be sure to select the mesh so that it is not so coarse that it loses be done. Those skilled in the art will be able to readily determine optimal mesh parameters.

The effective dimensions of the article when used in the shoulder joint are 0.2 to 10 mm fabric thickness and , 3 (1,0 to 14 (lO)), preferably about 50.11 to 120.01 (e.g. 50.60 or 70 mm) and a length of 20.0 to 60.0 mm, preferably about Wide end diameter of 30.0 to 50.0 mm (e.g. 381M) and 50 to 200 mm , preferably about 13.0 to 20. ha (e.g. 160 or 19,0mm) and a narrow end diameter. However, in general, the head The shaft rather than the head of the component passes through the narrow end, and the wide end is normally connected to this head. will house the glenoid fossa. These dimensions therefore depend on the type of head component. It may vary depending on the type, patient, and whether the joint is the knee or shoulder◇ In use, this head component is inserted through the device and into the bone; The article can be used to repair the rotator lamina muscle by conventional surgical techniques (i.e., typically suturing). and/or attached to the tumor.

A fabric into which tissue grows to strengthen a joint, such as a knee joint. Traditionally, these textiles have been used to connect prostheses and Instead of being attached to the pivot plate, it has been attached to the sternum.

In the following, specific embodiments of the invention will be described with reference to the accompanying drawings, which Figures 1 to 6 of the drawings show a very basic model of this article knitted from wool.
