Problems solved by technology

Surgical joint release is often combined with the use of external fixators to achieve the desired therapeutic effect. After surgery, the external fixator can be fixed or movable. When the external fixator is movable, the patient needs to exercise actively. However, due to the patient's tolerance to pain and exercise itself The ability is different, and the treatment effect is not clear. Due to the existence of external fixation brackets, the use of CPM machines is limited, and good continuous passive motion of joints cannot be performed. At the same time, the existing external fixation brackets do not have the possibility of continuous passive motion of joints. , its practical application is limited by
Moreover, the general bracket structure is relatively complicated, the operation is troublesome, the product assembly is complicated, the price is expensive, and the function is single.

Embodiment 1

[0041] Embodiment 1 Fixed bracket 1 and system

[0042] In this embodiment, the fixed bracket 1 is as figure 1 , figure 2 As shown, the fixed bracket includes a bone needle seat and a bone needle; the bone needle seat includes a first bone needle seat and a second bone needle seat; the bone needle seat is provided with a connecting device, and the connecting device has a first The form and the second form; the bone needle seat is provided with a mounting hole 11 / 21 and a locking device 14 / 24 (including a threaded hole and an outer hexagonal bolt), and the mounting hole is used to install the bone needle, not shown in the figure; The above-mentioned locking device is used to fix the bone needle. The bracket includes a first spicule seat 2 and a second spicule seat 1, the connecting device at the end of the first spicule seat 2 is a first form, that is, a through hole 22 penetrating up and down; the end of the second spicule seat 1 is a connecting device The second form is t...

Embodiment 2

[0045] Embodiment 2 Fixed bracket 2 and its system

[0046] Fixing bracket 2 such as Figure 1-Figure 4 As shown, in addition to including the first bone needle seat, the second bone needle seat, and the bone needle, a third bone needle seat 3 is also included. One end of the third bone needle seat 3 is provided with a through hole 35, and an insertion hole is arranged around the through hole. 36, a semicircular end 37, the other end is provided with a pivot 32, the head of the pivot is provided with an internal gear 321, and the tail of the pivot is a screw thread 322, which can fix two bone needle seats through nuts, and this end is also a semicircular end 33. Specifically, the fixing bracket 2 is sequentially formed by connecting the second spicule seat, the third spicule seat and the first spicule seat.

[0047] The fixed bracket system is basically the same as that in Example 1, but the mechanical arm is provided with a power jack and a nickel-metal hydride battery, whi...

Embodiment 3

[0048] Embodiment 3 Fixed bracket 3

[0049] The structure of the fixed bracket 3 is as follows: Figure 4 As shown, but a ring of flanges is arranged around the through holes of the first bone needle seat and the third bone needle seat, and a plurality of jacks are arranged on the flange, and the pivots of the second bone needle seat and the third bone needle seat A plurality of threaded holes are arranged on the shaft. After the bone needle seats are pivotally connected, after the bone needle seats are fixed at an angle to each other, the bolts are screwed into the insertion holes and the threaded holes, so that the fixed bracket is fixed. The bone needle is fixed on the affected part of the human body through the installation hole, and the affected part can be fixed.

Abstract

The invention provides a fixing bracket and a system thereof. The fixing bracket comprises bone needle seats and a bone needles; the bone needle seats comprise a first bone needle seat and a second bone needle seat; each bone needle seat is provided with a connecting device; the connecting devices are respectively in a first form and a second form; the bone needle seats are detachably and rotatably pivoted with each other through the first form and the second form of the connecting devices; and installation holes and locking devices are respectively arranged on the bone needle seats, wherein the installation holes are used for installing the bone needles, and the locking devices are used for fixing the bone needles. The fixing bracket system also comprises a power system, a communication system and a control system. The fixing bracket and the system thereof have the advantages of simple structure, convenient assembly, wide application range and various functions.

Description

technical field [0001] The invention relates to a medical device, in particular to an external bone fixation bracket used in surgery and a system thereof. Background technique [0002] Joint dysfunction can be caused by a variety of etiologies, such as scar contracture and scar hyperplasia at the joint site, tendon, muscle and nerve injury, fracture, etc. after trauma (burn) injury. Patients often present with varying degrees of limited range of motion, loss of range of motion, and joint deformity. At present, the treatment of joint dysfunction is mainly joint continuous passive motion (CPM) machine exercise, manual or surgical joint release. CPM machine exercise is mainly used for joint replacement and joint release. When no exercise is performed, other auxiliary braces are often needed to maintain the joint position. It cannot be used alone for joint deformities caused by scar contractures and joint dysfunction caused by nerve damage. Rehabilitation treatment; at the sam...
