Description

Novel fixing device and method for limiting forearm rotation

Technical Field

The invention belongs to the technical field of auxiliary external fixation of wrist joints after orthopedic wrist surgery, and particularly relates to a novel fixing device and method for limiting forearm rotation.

Background

After the wrist joint operation, plaster or braces and the like are often needed to fix and limit the movement of the wrist joint so as to ensure good healing of the bone or ligament. But the movement directions of the wrist joints include flexion, extension, radial deviation, ulnar deviation, pronation and supination. Pronation and supination, i.e., rotation of the forearm, are also the movements involved in the wrist joint, thus affecting the recovery from wrist joint disease. In order to achieve the above effects, semi-tubular and tubular long-arm plasters or braces are used clinically. Cast plaster is not conducive to the viewing and dressing change of the wrist wound. The plaster of longarm restricts the above-mentioned movement of the wrist joint and fixes the elbow joint, so that the complication of stiff elbow joint is frequently occurred, and the patient with fixed period feels uncomfortable because the elbow cannot be bent or stretched.

Disclosure of Invention

The technical problem to be solved by the invention is to provide a novel fixing device and a novel fixing method for limiting forearm rotation, which can limit the forearm rotation of a patient and simultaneously fix the motion of an elbow joint, avoid discomfort and elbow joint stiffness complications caused by incapability of moving the elbow of the patient, and facilitate the examination and dressing change of a palm side or back side wound.

The technical scheme adopted by the invention for solving the technical problem is to provide a novel fixing device for limiting the rotation of the forearm, which comprises a fixing plate, wherein the fixing plate is of a U-shaped structure with unequal arm lengths, the long arm length of the fixing plate is matched with the distance from the palm part of a human body to the rear part of the elbow, the short arm length of the fixing plate is matched with the distance from the middle point of the forearm of the human body to the rear part of the elbow, and the inner surface of the fixing plate is matched with the structural curve of the forearm of the human body.

In a preferred embodiment of the present invention, the long arm of the fixing plate is a two-section type telescopic structure.

As another preferred embodiment of the present invention, the root parts of the two arms of the fixing plate are respectively provided with a limiting plate correspondingly, the installation direction of the limiting plate is consistent with the plane direction of the two arms of the fixing plate, and the installation position of the limiting plate corresponds to the fixed position of the upper arm of the human body.

As a further improvement to the above embodiment, the limiting plate is semicircular.

In another preferred embodiment of the present invention, the fixing plate is provided with a plurality of restriction bands for fixing the forearm of the human body.

As a further improvement of the above implementation method, the restraint band is provided with 3 bands which are all fixed on the long arm of the fixing plate, the 3 bands are sequentially arranged at the front end of the long arm of the fixing plate, between the front end of the long arm and the front end of the short arm on the long arm and at the position corresponding to the front end of the short arm on the long arm from front to back, and the restraint band corresponding to the front end of the short arm can be connected with the front end of the short arm.

Another technical solution adopted by the present invention to solve the technical problem is to provide a method for using the above-mentioned novel forearm rotation-limiting fixing device, comprising the following steps:

(1) When the wound is positioned on the back side of the wrist of the patient, the fixing plate is sleeved on the forearm of the patient, the fixing plate is wrapped to the midpoint of the forearm from the palm side of the wrist to the back of the elbow, and the forearm of the patient is wound and fixed through a restraint strap or a medical bandage carried by the fixing plate;

(2) When the wound is positioned on the palm side of the wrist of the patient, the fixing plate is sleeved on the forearm of the patient, the fixing plate is wrapped to the midpoint of the forearm from the back side of the wrist along the palm to the back of the elbow, and the forearm of the patient is wound and fixed through a restraint strap or a medical bandage carried by the fixing plate.

Advantageous effects

Firstly, the forearm of a patient is fixed by the U-shaped fixing plate with unequal arm length, and the elbow joint of the patient is not limited, so that the rotation of the forearm of the patient is limited, the movement of the elbow joint is not limited, and the discomfort caused by the incapability of moving the elbow and the complication of the stiffness of the elbow joint of the patient are avoided; in addition, the U-shaped fixing plate with unequal arm lengths can select a proper fixing method according to the wound position of the wrist of the patient, so that the wound (on the palm side or the back side) of the wrist of the patient cannot be shielded by a fixed object, and medical staff can check and change the dressing conveniently.

Detailed Description

The invention will be further illustrated with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teaching of the present invention, and such equivalents may fall within the scope of the present invention as defined in the appended claims.

The novel fixing device for limiting the rotation of the forearm as shown in fig. 1 and 2 comprises a fixing plate 1, wherein the fixing plate 1 is in a U-shaped structure with unequal arm length as shown in fig. 3. The long arm of the fixing plate 1 is of a two-section type telescopic structure, the length of the fixing plate can be adjusted to be matched with the distance from the palm part of a human body to the rear part of the elbow when the fixing plate is used, and the length of the short arm is matched with the distance from the middle point of the forearm of the human body to the rear part of the elbow. The inner surface of the fixing plate 1 is matched with the structural curve of the forearm of the human body.

The root of 1 two arms of fixed plate corresponds respectively and is equipped with semicircular limiting plate 2, and the planar direction of limiting plate 2's the direction of setting and 1 two arms of fixed plate is unanimous, and the fixed position that sets up position and human upper arm is corresponding, and limiting plate 2 can effectively restrict the forearm rotation. Can be equipped with on fixed plate 1 about band 3 and fix the human forearm, about band 3 is equipped with 3 and all fixes and on the long arm of

fixed plate

1, 3 about bands 3 from preceding to back set gradually in the long arm front end of fixed plate 1, on the long arm between long arm front end and the short arm front end and the long arm on correspond the position of short arm front end, be connected to the short arm front end when corresponding about band 3 of short arm front end position uses and fix the forearm. Of course, the fixing plate 1 may be wound and fixed on the forearm of the patient by using other medical bandages without providing the restraining band 3.

The following provides a use method of the novel forearm rotation limiting fixing device, which comprises the following steps:

This wrist joint fixing device adopts the U type fixed plate 1 of arm length such as non-to fix patient's forearm, and patient's elbow joint is unrestricted to can not restrict elbow joint's activity when restricting patient's forearm rotation, avoid the uncomfortable of patient because of elbow can not move about and feel and the stiff complication of elbow joint. In addition, the U-shaped fixing plate 1 with unequal arm length can select a proper fixing method according to the wound position of the wrist of the patient, so that the wound (on the palm side or the back side) of the wrist of the patient cannot be shielded by a fixed object, and medical staff can conveniently check and change the dressing for the wound.
