Description

Technical Field

[0001] The utility model belongs to the field of clinical teaching, in particular to a multifunctional simulation operation platform for orthopedic clinical teaching. Background Art

[0002] At present, clinical teaching of orthopedics mostly stays in books, while the real learning of orthopedics requires clinical operations. However, patients are often used for teaching. Considering factors such as safety, rigor and patient compliance, the effect is often mediocre and cannot achieve a good teaching effect. In addition, even if a bone model is obtained, it cannot be effectively fixed and surgical simulation operations cannot be performed.

[0003] A multifunctional simulated surgical platform for orthopedic clinical teaching (CN113393728A) disclosed in a Chinese patent is firmly and conveniently clamped on a fixed desktop by two bases; and the second clamping port is connected by a universal joint to achieve arbitrary adjustment and fixation at multiple angles and in multiple directions; the second clamping port is used to clamp and fix the left clamping block and the right clamping block respectively, and cooperates with the movement of the left clamping block on the sliding rod to achieve the clamping of bones of any length; the application has a compact and simple structure, is convenient for teaching and practical work under various conditions, is convenient and firm to fix, has stable clamping, and is easy to disassemble.

[0004] The above device uses a push rod to resist the rotating joint ball, but since the joint ball is a curved surface, the contact area with the push rod is small, so the effect of the push rod on the joint ball is limited, or even ineffective. Utility Model Content

[0005] To solve the above problems, the utility model adopts the following technical solutions.

[0006] A multifunctional simulated surgical platform for orthopedic clinical teaching comprises a pair of connecting seats, a ball joint shaft is rotatably connected to the connecting seats, a connecting column is integrally connected to the ball joint shaft, a slide is connected to the upper surface of the connecting column, a fixed clamp block and a movable clamp block are connected to the slide, a vertical beam is clamped by the fixed clamp block and the movable clamp block, a clip is provided on the front surface of the vertical beam, a fourth screw rod is penetrated through the upper end of one of the vertical beams, the clip on the front surface of the vertical beam is connected to the fourth screw rod, a connecting rod is fixedly inserted on the front surface of the lower end of the other vertical beam, and the vertical beam provided with the fourth screw rod is slidably connected to the connecting rod.

A third screw is connected to the inside of the slide by a bearing, and a screw sleeve is integrally connected to the lower surface of the movable clamping block and connected to the third screw. One end of the third screw passes through one end of the slide and extends to the outside.

[0008] A sleeve is installed at the rear end of the vertical beam slidably connected to the connecting rod. The sleeve passes through from top to bottom, and the bottom of the sleeve contacts the upper surface of the connecting rod. A bolt is connected to the inner thread of the sleeve. When the bolt moves downward in the inner thread of the sleeve, the bottom of the bolt contacts the upper surface of the connecting rod, so that the vertical beam is fixed on the connecting rod by friction.

[0009] A boss is integrally connected to the side of the connecting seat, and the connecting seat and the boss are both hollow structures. A second screw is threadedly connected to the boss. A tray is provided inside the connecting seat and on the lower surface of the ball joint shaft, and a connecting rod is provided on the lower surface of the tray, and the other end of the connecting rod is located below the second screw.

[0010] The tray is an arc-shaped structure as a whole, the upper surface of the tray is fitted with the lower surface of the ball joint shaft, and the center of the connecting rod connected to the tray is connected to the inner wall of the connecting seat through a rotating shaft.

[0011] A connecting elbow is integrally connected to the side surface of the connecting seat, a first screw is threadedly connected to the connecting elbow, and the first screw passes through the front end of the connecting elbow and is connected to a resistance plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The multifunctional simulated surgical platform for orthopedic clinical teaching in the present application can help to complete vivid preoperative teaching of orthopedics and assist in the simulated operation of the skills required for surgery. The device can be clamped and fixed on the podium by using the contact plate and the connecting seat. The angle of the bone fixation mechanism can be adjusted by the ball joint axis, so as to facilitate the forward display of bone details. A slide is provided on the ball joint axis, and a fixed clamp block and a movable clamp block are provided on the slide. The bone fixation mechanism can be clamped by the fixed clamp block and the movable clamp block so as to be connected to the connecting seat and the ball joint axis as a whole. The bone fixation mechanism in the present application specifically includes a pair of vertical beams, and the vertical beams are provided with clips to fix the bones. Taking into account the different lengths of the bones, a connecting rod is provided on one of the vertical beams, and the other vertical beam is slidably connected to the connecting rod, so that the distance between the two clips can be adjusted, and the clips on the slidable vertical beams can be extended and retracted by screws to achieve fine-tuning.

[0014] Since the ball joint shaft is rotatably embedded in the connecting seat, when the skeleton is displayed, the weight of the skeleton may cause the ball joint shaft to rotate and cause the skeleton to fall. Therefore, a fixing mechanism needs to be set for the ball joint shaft to fix the ball joint shaft after the adjustment is completed. Therefore, the present application is provided with a tray, a connecting rod and a second screw. The second screw moves downward to abut against the connecting rod. The connecting rod is subjected to force to form a lever movement to abut the tray against the lower surface of the ball joint shaft, thereby using friction to fix the ball joint shaft.

The movable clamping block 104b on the slide 104 can move toward the fixed clamping block 104a to clamp and fix the vertical beam 105. Further, due to the different lengths of the bones, a fourth screw 105c is provided on the upper end of one of the vertical beams 105, and the clip 105b on the front surface of the vertical beam 105 is connected to the fourth screw 105c. The fourth screw 105c can be used to fine-tune the clip 105b connected thereto, so that the device When fixed on the podium, the fourth screw 105c can be rotated to adjust the distance between the two clips 105b.

Specifically, a connecting rod 105a is fixedly inserted on the front surface of the lower end of another vertical beam 105, and the vertical beam 105 with the fourth screw 105c is slidably connected to the connecting rod 105a. One of the vertical beams 105 can slide on the connecting rod 105a so that the distance between the vertical beam 105 and the other vertical beam 105 can be adjusted.

[0026] exist Figure 1 and Figure 2 In order to realize the movement of the movable clamping block 104b relative to the fixed clamping block 104a and achieve the purpose of clamping, a third screw 104c is connected to the slide 104 by a bearing, and the lower surface of the movable clamping block 104b is integrally connected with a screw sleeve connected to the third screw 104c, one end of the third screw 104c passes through one end of the slide 104 and extends to the outside.
