[0019] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0020] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0021] Reference Figures 1 to 4 As shown, this embodiment provides a scapula joint fixation device (hereinafter referred to as the fixation device), the fixation device includes a fixing member 1 for fixing the glenoid 2 and the lateral edge 3 of the scapula, as shown in FIG. Figure 1The fixture 1 shown includes a first fixture portion 11 for applying the glenoid cavity 2, a second fixture portion 13 for applying the lateral edge 3, and a connecting portion 12 connected between the first fixture portion 11 and the second fixture portion 13 to ensure that the shape of the fixture 1 matches the anatomical structure of the scapula.

[0022] The first fixing portion 11 has a plurality of first locking screw holes 111 arranged at intervals, and the second fixing portion 13 has a plurality of second locking screw holes 131 arranged at intervals. The screws are respectively passed through the first locking screw holes 111 and the second locking screw holes 131, and then respectively nailed into the corresponding glenoid 2 and the lateral edge 3 to ensure that the first fixing portion 11 and the second fixing portion 13 are respectively fixed to the glenoid 2 and the lateral edge 3, thereby ensuring that the entire fixing component 1 is fixed to the scapula by plate nail fixing.

[0023] like Figure 2 and Figure 3 As shown, the first fixing portion 11 also has a plurality of guide pin holes 112 which are arranged at intervals and close to the side of the glenoid 2, and a suture groove 113 which matches the guide pin hole 112 is arranged on the back side of the first fixing portion 11 facing the glenoid 2, the suture groove 113 is provided with a notch 114 facing the side of the glenoid 2, and one end of the suture groove 113 passes through the edge 115 of the first fixing portion 11, and the other end is connected to the guide pin hole 112 to form a sutureable setting for the glenoid 2.

[0024] When suturing is required, the back of the first fixing part 11 is first placed close to the surface of the glenoid 2, and then the Kirschner guide wire with the suture 4 is passed through the upper opening of the guide wire hole 112, and then passed out from the lower opening of the guide wire hole 112, and then passed through the edge 115 of the first fixing part 11 along the groove in the suture groove 113, and then the Kirschner guide wire is pierced through the structural tissue of the glenoid 2, and the Kirschner guide wire is passed around the glenoid 2 and passed through the guide wire hole 112 again, and the operation is repeated many times to achieve the following. Figure 4 The sutures 4 shown are used to suture and fix various parts of the injured glenoid cavity 2, and the notch 114 of the suture groove 113 can provide space for the suture 4 to facilitate the suturing operation during the operation. At the same time, the suture groove 113 serves to limit the suture 4 to prevent the suture 4 from shifting or dislocating after the operation, thereby avoiding affecting the postoperative fixation.

[0025] The first locking screw holes 111 of the first fixing part 11 and the second locking screw holes 131 of the second fixing part 13 are respectively matched with screws to respectively fix the glenoid fossa 2 and the lateral edge 3 of the scapula with plates and nails, thereby achieving combined fixation of the scapula.

[0026] When an unexpected severe fracture occurs at the glenoid 2 of the scapula, especially a comminuted fracture, the glenoid 2 of the scapula can be sutured and fixed with sutures 4 through the cooperation of multiple guide pin holes 112 and suture grooves 113. Temporary fixation during the operation can also be implemented according to the actual situation of the operation.

[0027] In another preferred embodiment, the fixing member 1 is integrally formed to avoid the need for the doctor to manually connect the first fixing portion 11, the connecting portion 12 and the second fixing portion 13 together during the operation, thereby saving operation time and bringing greater convenience to the surgical operation.

[0028] Further preferably, the angle between the length direction of the first fixing portion 11 and the length direction of the second fixing portion 13 is greater than 90 degrees, so that the fixing member 1 is arranged in an oblique L shape, so as to further ensure that the shape of the fixing member 1 matches the anatomical structure of the scapula.

[0029] In another preferred embodiment, the aperture of the first locking screw hole 111 is smaller than that of the second locking screw hole 131. Since the length of the glenoid 2 is smaller than the length of the outer edge 3, the first locking screw hole 111 corresponding to the glenoid 2 is set as a small hole, and the second locking screw hole 131 corresponding to the outer edge 3 is set as a large hole, so that the doctor can drill holes with different suitable apertures on the scapula, which can further reduce postoperative damage to the patient.

[0030] In another preferred embodiment, the side wall of the second fixing portion 13 is provided with a plurality of inwardly concave arc-shaped grooves 132 to form a slim waist configuration.

[0031] In this embodiment, a plurality of arc-shaped grooves 132 are arranged along the length direction of the second fixing portion 13, and are respectively located on both sides of the second fixing portion 13 in the width direction. During the operation, the doctor uses the arc-shaped grooves 132 of the second fixing portion 13 to narrow the local width of the second fixing portion 13 according to the actual injury of the patient, that is, to make it waist-shaped, so as to facilitate the partial bending of the second fixing portion 13 to the specific injury site of the patient, so as to ensure the fixing effect of the second fixing portion 13 on the outer edge 3 of the patient.

[0032] In another preferred embodiment, the connecting portion 12 has a coupling hole 121 penetrating through the upper and lower surfaces thereof.

[0033] By setting the combining hole 121 to be composed of a threaded hole part and a pressurized hole part, during surgery, it is convenient for the doctor to select the threaded hole or the pressurized hole for fixation according to the actual situation on site, so as to further ensure that the connecting part 12 of the fixing device 1 is firmly fixed at the connecting part 12 between the glenoid 2 and the lateral edge 3.

[0034] Although the present invention has been specifically demonstrated and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes may be made to the present invention in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims, all of which are within the scope of protection of the present invention.
