Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a supporting device for percutaneous endoscopic cervical discectomy. Background Art

[0002] With the change of medical model, humanistic service has become an important part of the intangible assets of the hospital, and the concept of humanistic care has been accepted by the majority of nursing staff. People-oriented service is the direction and trend of the development of modern operating room nursing. Percutaneous endoscopic cervical discectomy (PECD) has attracted more and more attention from patients and medical staff.

[0003] Any surgical position must focus on the patient's comfort and the full exposure of the surgical field. However, the position of percutaneous endoscopic cervical discectomy (PECD) has very strict requirements on the exposure of the surgical field, so that each patient can effectively see through the C-arm fluoroscopy machine and perform the operation better. However, most of the operating tables in the operating room are corresponding accessories with relatively simple functions. Therefore, how to design a support device based on the characteristics of percutaneous endoscopic cervical discectomy (PECD) surgery, that is, how to effectively meet the requirements of the surgical principles of percutaneous endoscopic cervical discectomy, to meet the requirements of effective fluoroscopy and surgery in percutaneous endoscopic cervical discectomy, especially in prone position posterior percutaneous endoscopic cervical discectomy surgery, to avoid the surgical table blocking the surgical field and C-arm fluoroscopy machine, and increase the effectiveness of the patient's surgery, has become a problem that needs to be solved urgently.

[0020] Compared with the prior art, when the support device for percutaneous endoscopic cervical discectomy provided by the utility model is used, the device is first placed at the head of the operating bed, and is tied and fixed to the operating bed by a fixing belt, so as to avoid the problem of displacement of the support plate due to the smooth surface of the transparent support plate. By sliding the position of the adjustment slider in the T-shaped slide groove, the connection position of the fixing belt and the operating bed can be adjusted, so as to meet the requirements of connection and fixation with operating beds of different models; then, the secondary transparent support plate is manually slid out of the accommodating cavity and extended out of the front end of the main transparent support plate by the handle; then, the patient is allowed to lie on the operating bed and the upper body of the patient is suspended by the main and secondary transparent support plates, thereby effectively performing surgical fluoroscopy, ensuring the comfort and safety of the patient, and facilitating the operation of the surgeon. Therefore, the device can effectively meet the requirements of the surgical principles of percutaneous endoscopic cervical discectomy (PECD), that is, the style of the support device for percutaneous endoscopic cervical discectomy provided by the utility model is determined according to the characteristics of the percutaneous endoscopic cervical discectomy (PECD) surgery, and can be extended by sliding the auxiliary transparent support plate out of the accommodating cavity. On the basis of meeting the requirements of the PECD surgery for transparency, it can adapt to the needs of patients with different physical conditions and surgical sites. It is economical, highly clinically applicable, convenient, safe and practical, and has been unanimously praised by doctors and nurses.

[0021] As a specific example, please refer to Figure 2 As shown, the main transparent support plate 1 and the secondary transparent support plate 2 both include a plane support plate 21, a left arc-shaped blocking plate 22 and a right arc-shaped blocking plate 23. The left arc-shaped blocking plate 22 is integrally formed on the left side of the plane support plate 21, and the right arc-shaped blocking plate 23 is integrally formed on the right side of the plane support plate 21. By adopting the technical solution in this embodiment, on the one hand, the upper body of the patient can be suspended by the plane support plate 21, and on the other hand, the upper body of the patient can be blocked by the left arc-shaped blocking plate 22 and the right arc-shaped blocking plate 23 to prevent the upper body of the patient from sliding off the plane support plate 21, thereby better ensuring the safety of the patient. Of course, based on the aforementioned embodiments, those skilled in the art may also design the main transparent support plate 1 and the secondary transparent support plate 2 as follows Figure 1 The entire flat plate structure shown can also provide suspended support for the patient's upper body.

[0022] As a specific embodiment, the main transparent support plate 1 and the secondary transparent support plate 2 are acrylic plates, that is, the main transparent support plate 1 and the secondary transparent support plate 2 are made of existing acrylic (also called PMMA or plexiglass) materials, which not only have good transparency (can be seen through during surgery), but also have beautiful appearance, good corrosion resistance and chemical stability.

[0023] As a specific example, please refer to Figure 1 and Figure 2 As shown, convex strips 11 are provided on the left and right inner walls of the accommodating cavity, and grooves 20 are provided on the left and right sides of the secondary transparent support plate 2 to slide with the convex strips 11. Thus, through the sliding cooperation between the convex strips 11 and the grooves 20, it is easy to realize that the secondary transparent support plate 2 slides out of the accommodating cavity and extends out of the front end of the main transparent support plate 1, which is convenient and quick. Of course, those skilled in the art can also set grooves on the left and right inner walls of the accommodating cavity and set convex strips on the left and right sides of the secondary transparent support plate 2 to achieve cooperation based on the above embodiments.

[0024] As a specific example, please refer to Figure 1 and Figure 2 As shown, the left and right sides of the main transparent support plate 1 are provided with through holes that penetrate the accommodating cavity, and the through holes are provided with locking knobs 7 that abut against the left and right sides of the secondary transparent support plate 2. Therefore, the secondary transparent support plate 2 can be prevented from sliding in the accommodating cavity of the main transparent support plate 1 by the abutting contact between the locking knob 7 and the left and right sides of the secondary transparent support plate 2, thereby effectively improving the support effectiveness and comfort for the upper body of the patient.

[0025] As a specific embodiment, the main transparent support plate 1 has a length of 60 cm, a width of 60 cm, and a thickness of 10 cm, and the secondary transparent support plate 2 has a length of 30 cm, a width of 50 cm, and a thickness of 6 cm. Thus, while achieving effective support for the upper body of the patient, it can also prevent the main and secondary transparent support plates from being crushed due to insufficient thickness, thereby ensuring that a corresponding effective distance can be maintained between the surgical patient and the C-arm fluoroscopy machine.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
