Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary tools, in particular to a telescopic work-shaped frame used in scoliosis correction surgery. Background Art

[0002] For patients with scoliosis, when the spinal curvature reaches a certain degree, surgical correction is required. During the correction process, pedicle screws are needed to correct the scoliotic spine. The overall balance of the spine needs to be evaluated during the correction process. Otherwise, after the correction operation, the spine may tilt and become unbalanced, leading to failure of the correction.

[0003] Currently, the tool commonly used to assess balance during surgery is the "T"-shaped frame, which needs to be disinfected before surgery and used during surgery. The disadvantage of the "T"-shaped frame is that its length is fixed and the height of each patient is different. If the "T"-shaped frame is too long, it will affect disinfection. If the "T"-shaped frame is too short, it cannot be placed at the prepared anatomical landmark point. Utility Model Content

[0009] According to a preferred technical solution, a rotating rod is rotatably arranged inside the slide groove, threads with opposite rotation directions are arranged at both ends of the rotating rod, and a threaded hole is arranged on the slider portion to cooperate with the threaded rotating rod.

[0010] According to a preferred technical solution, a rotating wheel is fixedly provided at the middle of the rotating rod, and anti-slip grooves are provided on the rotating wheel.

[0011] According to a preferred technical solution, a handle is provided at the lower portion of the body.

[0012] According to a preferred technical solution, a rotating plate is rotatably provided at the middle position of the upper part of the body, the lower end of the rotating plate is configured to be pointed, and a vertical marking line is marked at a position on the body near the lower end of the rotating plate.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The head, body, tail and other parts of the utility model can be contracted and extended. The head and the body form a "90°" angle, and the tail and the body also form a "90°" angle. The length and width can be adjusted according to specific circumstances during the operation. It is suitable for patients of different heights and body shapes and is easy to disinfect and carry.

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0020] like Figure 1As shown, a retractable work-shaped frame used in scoliosis correction surgery is characterized in that it includes a head 1, a body 2 and a tail 3, the middle position of the head 1 is fixedly set at the upper end of the body 2, the middle position of the tail 3 is fixedly set at the lower end of the body 2, the head 1, the body 2 and the tail 3 are all retractable structures in the length direction, and the body 2 forms an angle of 90° with the head 1 and the tail 3 respectively. A handle 13 is provided at the lower part of the body 2. A rotating plate 14 is rotatably provided at the middle position of the upper part of the body 2, and the lower end of the rotating plate 14 is set to a sharp angle. A vertical marking line 15 is marked on the body 2 near the lower end of the rotating plate 14.

[0021] like Figure 2 As shown, the telescopic structure includes an intermediate fixed plate 4 and an end movable plate 5, and the end movable plate 5 is slidably arranged at both ends of the intermediate fixed plate 4. A slide groove 6 is arranged on the intermediate fixed plate 4, and a slider portion 7 is arranged on the end movable plate 5, and the slider portion 7 is slidably arranged inside the slide groove 6. A rotating rod 8 is rotatably arranged inside the slide groove 6, and threads 9 with opposite rotation directions are respectively arranged at both ends of the rotating rod 8, and a threaded hole 10 that cooperates with the threaded rotating rod 8 is arranged on the slider portion 7. A rotating wheel 11 is fixedly arranged in the middle of the rotating rod 8, and an anti-slip pattern 12 is arranged on the rotating wheel 11.

[0022] This embodiment needs to be disinfected before surgery to ensure the sterility of the instrument to avoid the risk of infection. During surgery, the head end 1 of the retractable I-shaped frame is placed on the patient's shoulders on both sides, the body 2 is located in the center of the spine, and the tail end 3 is as high as the upper edge of the bilateral acetabulum. Such positioning can provide a reference mark for orthopedic balance. According to the needs during surgery, the length and width of the I-shaped frame can be adjusted according to the specific situation through the retractable structure, specifically by rotating the rotating wheel 11, thereby driving the end moving plate 5 to retract to both ends, so as to adjust the length and width of the I-shaped frame to adapt to patients of different heights and body shapes. During the adjustment process, the design features of the head and body forming a "90°" angle, and the tail and body also forming a "90°" angle can be used. With the reference guidance of the I-shaped frame, the doctor can evaluate the overall balance of the spine to ensure that the orthopedic effect during surgery reaches the expected result. After determining the correct positioning and adjustment, the doctor can perform scoliosis correction surgery. This embodiment can be used vertically in the later stage of rehabilitation. The cooperation between the rotating plate 14 and the vertical marking line 15 can ensure that it will not be tilted, so as to better evaluate the patient's rehabilitation status.

[0023] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
