Description

A New Type of Postoperative Fixation Brace for Limiting Forearm Rotation

technical field

The utility model belongs to the technical field of auxiliary external fixation of the wrist joint after orthopedic wrist surgery, in particular to a novel postoperative fixation support for restricting the rotation of the forearm.

Background technique

After wrist joint surgery, plaster or braces are often required to limit the movement of the wrist joint to ensure good bone or ligament healing. However, the directions of movement of the wrist joint include flexion, extension, radial deviation, ulnar deviation, pronation, and supination. Pronation and supination, that is, the rotation of the forearm, are also movements in which the wrist joint participates, and thus also affect the recovery of wrist joint diseases. In order to achieve the above-mentioned effects, half-pipe and cast long-arm casts or braces are now clinically used. Cast plaster is not conducive to the inspection and dressing of wrist wounds. The long arm plaster restricts the above-mentioned activities of the wrist joint and fixes the elbow joint at the same time, so complications of elbow joint stiffness often occur, and patients in the fixed period also feel uncomfortable because the elbow cannot be flexed or extended.

Utility model content

The technical problem to be solved by the utility model is to provide a new type of postoperative fixation brace that limits the rotation of the forearm, which can limit the rotation of the patient's forearm while not fixing the movement of the elbow joint, so as to avoid the patient's discomfort caused by the inability of the elbow Sensitivity and complications of elbow joint stiffness, convenient for inspection and dressing change of volar or dorsal wounds.

The technical scheme adopted by the utility model to solve its technical problems is to provide a new type of postoperative fixation brace for restricting the rotation of the forearm, including a fixation plate, which is a U-shaped structure with non-equal arm lengths, and the The length of the long arm matches the distance from the palm of the human body to the back of the elbow, the length of the short arm matches the distance from the midpoint of the forearm to the back of the elbow, and the inner surface of the fixing plate matches the structural curve of the forearm of the human body.

As a preferred embodiment of the present invention, the long arm of the fixing plate is a two-stage telescopic structure.

As another preferred embodiment of the present utility model, the roots of the two arms of the fixing plate are respectively provided with limiting plates, the setting direction of the limiting plates is consistent with the plane direction of the two arms of the fixing plate, and the setting position is the same as that of the upper arm of the human body. corresponding to the fixed position.

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

As another preferred embodiment of the present invention, the fixing plate is provided with a plurality of restraint straps to fix the forearm of the human body.

As a further improvement to the above-mentioned implementation method, there are three restraint straps and they are all fixed on the long arm of the fixed plate, and the three restraint straps are sequentially arranged on the front end of the long arm of the fixed plate and the upper long arm of the long arm from front to back. The position between the front end and the front end of the short arm and on the long arm corresponds to the front end of the short arm, and the restraint belt corresponding to the front end of the short arm can be connected to the front end of the short arm.

Beneficial effect

First of all, the utility model uses a U-shaped fixing plate with non-equal arm length to fix the patient's forearm, and the patient's elbow joint is not restricted, so that the rotation of the patient's forearm can be limited while the movement of the elbow joint is not restricted, and the patient's Discomfort caused by the immobility of the elbow and complications of elbow joint stiffness; in addition, this U-shaped fixed plate with non-equal arm length can choose an appropriate fixation method for the wound position of the patient's wrist, so that the patient's wrist (palm) side or back) wounds will not be covered by fixtures, so that it is convenient for medical staff to check the wound and change the dressing.

Detailed ways

Below in conjunction with specific embodiment, further set forth the utility model. It should be understood that these embodiments are only used to illustrate the present utility model and are not intended to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by the appended claims of the application.

A new postoperative fixation brace for restricting the rotation of the forearm as shown in FIGS. 1 and 2 includes a fixation plate 1 , which is a U-shaped structure with unequal arm lengths, as shown in FIG. 3 . The long arm of the fixed plate 1 is a two-stage telescopic structure, and the length can be adjusted to match the distance from the palm of the human body to the back of the elbow during use, and the length of the short arm matches the distance from the midpoint of the forearm to the back of the elbow of the human body. . The inner surface of the fixing plate 1 matches the structural curve of the forearm of the human body.

The roots of the two arms of the fixed plate 1 are respectively provided with a semicircular limiting plate 2, the setting direction of the limiting plate 2 is consistent with the plane direction of the two arms of the fixed plate 1, and the setting position corresponds to the fixed position of the upper arm of the human body. The bit plate 2 can effectively limit the rotation of the forearm. The fixed plate 1 can be provided with a restraint band 3 to fix the forearm of the human body. There are three restraint bands 3 and they are all fixed on the long arm of the fixation plate 1. The front end of the long arm, the position between the front end of the long arm and the front end of the short arm on the long arm and the position corresponding to the front end of the short arm on the long arm, and the restraint belt 3 corresponding to the front end position of the short arm are connected to the front end of the short arm to fix the forearm during use. Certainly, the restraint belt 3 may not be provided on the fixing plate 1, and other medical bandages may be used to wrap and fix the patient's forearm.

The following provides a method for using the novel postoperative fixation brace that limits the rotation of the forearm, including the following steps:

(1) When the wound is located on the dorsal side of the patient's wrist, put the fixed plate on the patient's forearm and make the fixed plate wrap around the forearm from the palm side of the wrist to the back of the elbow to the midpoint of the forearm, and then pass the fixed plate. Wrap and fix the patient's forearm with a restraint belt or medical bandage;

(2) When the wound is located on the palm side of the patient's wrist, put the fixed plate on the patient's forearm and make the fixed plate wrap around the forearm from the back of the wrist along the back of the palm to the back of the elbow to the midpoint of the forearm, and then pass the fixed plate itself. The patient's forearm is wrapped and fixed with a restraint belt or a medical bandage.

The fixed brace adopts a U-shaped fixed plate 1 of non-equal arm length to fix the patient's forearm, and the patient's elbow joint is not restricted, so that the rotation of the patient's forearm is restricted while the movement of the elbow joint is not restricted, and the patient is prevented from Discomfort from immobility of the elbow and complications of elbow stiffness. In addition, this U-shaped fixing plate 1 with non-equal arm length can select a suitable fixing method for the wound position of the patient's wrist, so that the patient's wrist (palm side or back side) wound will not be blocked by the fixation object, thereby facilitating The medical staff inspected the wound and changed the dressing.
