Description

A finger tendon sheath

technical field

The invention relates to a fixing device for a finger tendon sheath, in particular to a finger tendon sheath support for fixing the tendon and the tendon sheath after the tendon sheath of the finger is ruptured.

Background technique

A rupture of the tendon in a finger is usually not easy to recover after being sutured. Fingers are not easy to fix. Patients who use their fingers habitually and cannot use them in time will subconsciously contract and relax the muscles on the fingers, resulting in the displacement of tendons and tendon sheaths. In addition, the hand often touches other objects and exerts a certain pressure. On the one hand, these pressures will lead to forced flexion and extension of the fingers, and on the other hand, the pressure on the contact surface will lead to the displacement of the tendon sheath.

The tendon sheath secretes synovial fluid that promotes tendon healing, so faster healing of the tendon sheath can improve the speed and effectiveness of recovery. But to speed up the healing of the tendon sheath, it is necessary to stabilize the tendon sheath position.

Compared with other human body injuries, fingers have many joints, flexible muscles, and small tissue structure, and are the most commonly used parts in human daily life. So it is very difficult to stabilize the tendon sheath.

The Chinese patent (CN100389735C, elastic Achilles tendon splint) is relatively easy to use on the Achilles tendon, because there are few joints on the Achilles tendon, and the Achilles tendon can be fixed in a straight line. But it is basically inapplicable to fingers.

Another example is (CN201595966U, composite brace for the treatment of tenosynovitis) The purpose of this brace is to avoid flexion and extension of the fingers, and usually only restricts the movement of the fingers, and cannot achieve the effect of fixing the position of the tendon sheath.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a finger tendon sheath support that can stably fix the position of the finger tendon sheath and accelerate the recovery of the tendon sheath.

In order to achieve the above object, the present invention includes a fixing ring, the fixing ring includes two half rings, and an opening can be formed between the two half rings for clamping a finger into the fixing ring.

Preferably, the fixing ring is two mutually hinged half rings, and the free end is provided with a fixing connection device to fix the two half rings into a closed ring.

Further, the fixing rings are connected by connecting straps, and two connecting straps are provided, one is fixed with the top end of each fixing ring, and the other is fixed with the bottom end of each fixing ring.

Preferably, the connecting belt has a certain elasticity

The beneficial effects of the present invention are: 1. The fixing ring can effectively clamp the tendon sheath, promote the recovery of the tendon sheath, and then speed up the recovery of the tendon; 2. The fixing ring has a good prescribed effect, and at the same time avoids obstruction of blood supply, and ensures the recovery effect of fingers; 3. , The use of pressure screws and pressure tablets can effectively apply to different finger thicknesses and shapes. 4. The connecting belt can effectively stabilize the position of the fixing ring without hindering the flexion and extension of the fingers.

Detailed ways

The invention will be described in detail below with reference to the accompanying drawings.

As shown in Figures 1-7, a finger tendon sheath support includes a fixing ring 10, the fixing ring 10 includes two half rings, an opening can be formed between the two half rings, and the fingers are clamped into the fixing ring.

As indicated above, the fixed ring may be two mutually hinged half rings with fixed connection means at the free end to fix the two half rings into a closed ring. It can also be a C-shaped split ring as shown in Figure 1.

As shown in Figures 1-3, the fixing ring 10 is a C-shaped ring, which can be a notched circular ring or a notched oval ring, the opening faces the side of the finger, the bottom covers and touches the finger pulp, and the top covers Overlying and touching the skin on the upper side of the phalanx. In this way, the tendon sheath can be effectively clamped, and the blood supply will not be blocked, so as to avoid the occurrence of finger necrosis. The opening of the C-ring is 1/5-1/4 of the total length of the fixing ring 10. When the finger is placed horizontally, the included angle α of the opening toward the side of the finger is between 30-90 degrees.

In order to improve the stability of the position of the fixing ring 10, the inner side of the lower half ring 13 of the fixing ring 10 is provided with protrusions. The protrusions can be strip-shaped to form ridges. . The bumps can be rubber or plastic, or metal strips with diamond-shaped anti-skid textures.

Also as shown in FIGS. 4-6 , in order to improve the fixing stability of the fixing ring 10 , the lower half ring 13 is wider than the upper half ring 11 . When the lower half ring 13 is wider than the upper half ring 11 , multiple rings can be arranged inside the lower half ring 13 Ribs 14.

Since the shape and thickness of the fingers of the patients are quite different, it is still possible to set various standard specifications in time, and it may still not be able to adapt to different finger shapes. Therefore, a thread connecting the inner and outer sides of the upper half ring 11 is provided on the top of the upper half ring 11 The through hole, the threaded through hole is screwed with the pressure screw 20, a pressure piece 21 is fixed inside the upper half ring 11, both ends of the pressure piece 21 are fixed with the inner side of the upper half ring, the pressure piece 21 is an elastic piece, so The bottom end of the pressing screw 20 points to the middle of the pressing piece 21, and the middle of the pressing piece 21 is located just above the back of the finger. Twisting the pressure screw 20 can push the pressure piece 21 against the back of the finger, so that the size of the accommodation space in the fixing ring 10 can be adjusted to adapt to different finger thicknesses and shapes, so that the lower half ring 13 can reach the tendon sheath in the finger pulp. pressure.

When a brace needs to be worn on multiple knuckles of the finger, the multiple braces can be connected by connecting straps 30 to stabilize the position of the fixing ring 10. Two connecting straps 30 are provided, one connected to the top of each fixing ring 10. fixed, and the other is fixed with the bottom end of each fixing ring 10 . In addition, the connection belt 30 has a certain elasticity, so as to ensure that the fingers can be flexed and stretched, but can be flexed and stretched within a certain range, and have a certain fixing ability.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
