Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a surgical assistance device and a medical system. Background Art

[0002] Currently, there is a common challenge in some surgeries that require lifting the head and mandible: after the patient enters the surgical preparation state, the medical team must manually lift the patient's mandible or skull to perform the surgery. Generally, in such cases, a medical staff member needs to hold the patient's mandible (jaw) or head with one hand while performing other surgical operations with the other hand, such as anesthesia intubation; for adult patients with a larger body size, it may even require two medical staff members to cooperate to properly lift and fix their mandible or head to ensure the smooth progress of other operation processes. If a gastroscopy examination is being performed, such a holding posture needs to be maintained continuously, which places extremely high demands on the physical strength and endurance of the medical staff and also significantly increases the operation difficulty of the examination.

[0003] There are also some assistance devices on the current market, and these assistance devices face two major problems. On the one hand, some assistance devices are complex in design, which not only raises the production cost but also may make the operation process cumbersome and is not conducive to the efficient development of clinical work; on the other hand, the existing assistance devices perform poorly in terms of patient comfort.

[0029] According to one aspect of the present utility model, a surgical assistance device is provided. Referring to Figure 1 as shown, the surgical assistance device includes:

[0030] A mandibular support assembly 1 for stabilizing and lifting the mandibular part of a patient;

[0031] A head fixation assembly 2 that works in cooperation with the mandibular support assembly 1 for stabilizing the head of the patient;

[0032] Wherein, the head fixation assembly 2 includes a clamping mechanism 21, and a flexible washer 22 is arranged on the clamping mechanism 21, and the flexible washer 22 contacts the head of the patient.

[0033] From the above technical solutions, it can be seen that the present utility model has at least one of the following advantages and positive effects:

[0034] The surgical assistance device provided by the present utility model can effectively stabilize the patient's head and mandible through the combined use of the mandible support assembly 1 and the head fixation assembly 2. On the one hand, it can effectively reduce the accidental risks caused by the movement of the patient's head during the operation, such as cutting errors and instrument slippage, thus significantly improving the safety of the operation. On the other hand, it provides a stable surgical platform for doctors, which helps to improve the accuracy and success rate of surgical operations. In addition, due to the presence of the flexible gasket 22, it can better adapt to the contour of the patient's head, reduce the pressure and discomfort on the patient's head, and maintain a high level of comfort even during a long operation, which is beneficial to reducing the pain and discomfort of the patient.

[0035] It should be noted that the basic function of the surgical assistance device provided by the present utility model, which is to stabilize the head and mandible, is applicable to a variety of surgical scenarios involving the head, and has good versatility and wide applicability. It is widely applicable to different surgical scenarios, such as neurosurgery, otolaryngology surgery, anesthesia surgery involving tracheal intubation, or gastroscopy, etc.

[0036] On this basis, the present utility model does not make specific restrictions on the structure that can form the head fixation assembly 2. As an implementation manner, the clamping mechanism 21 can be designed as a whole, and the flexible gasket 22 is provided on the whole clamping mechanism 21. At this time, the flexible gasket 22 can be provided only on the part in contact with the patient's head, or it can be set to be adapted to the overall structure of the clamping mechanism 21, and the present utility model does not make specific restrictions.

[0037] Here, the flexible gasket 22 can be configured with a lining made of soft pad or memory foam material, or can be configured with a material having a high-density memory function, such as high-density memory foam or silica gel, etc., or can be configured with a gel material in some implementation manners. In addition, in order to maintain the hygiene during the operation and facilitate maintenance and replacement, the flexible gasket 22 and the clamping mechanism 21 can be set to be detachably connected, for example, realized by means of adhesion, tightening, nesting, etc., and the present utility model does not make specific restrictions.

[0038] Of course, those skilled in the art can also set the clamping mechanism 21 to be split-type to save production and manufacturing costs under the condition of being able to achieve the clamping function. For example, in some implementation manners, as shown in Figure 1 it can be designed that the clamping mechanism 21 includes a first fixing unit 211 and a second fixing unit 212, and the first fixing unit 211 and the second fixing unit 212 are arranged oppositely. In this way, the first fixing unit 211 and the second fixing unit 212 form two parts of the clamping mechanism 21, which operate independently but cooperate with each other to more precisely adapt to the shape and size of the patient's head.

[0039] In addition, to ensure unobstructed surgical vision, the first fixing unit 211 and the second fixing unit 212 can be designed with a low-profile structure, that is, on the premise of ensuring sufficient stability, their physical occupation around the surgical area is minimized as much as possible to avoid interfering with the surgical field of view or affecting the operating space of surgical instruments.

[0040] To adapt to the structure of the clamping mechanism 21, a flexible washer 22 can also be provided, which includes a first half-ring 221 and a second half-ring 222; the first half-ring 221 is provided on the first fixing unit 211, and the second half-ring 222 is provided on the second fixing unit 212. The first half-ring 221 fits against one part of the patient's head, and the second half-ring 222 fits against another part of the patient's head. This design not only increases the comfort of the contact surface with the patient's head but also deforms according to the subtle changes in the head contour, further improving the fitting degree and stability during fixation. In addition, this design evenly disperses the pressure in both the horizontal and vertical directions, reducing local pressure points, and can minimize patient discomfort even during a long-term fixation during the operation; in addition, compared with the integral design of the clamping mechanism 21, the dual-unit design can also minimize the production and manufacturing costs to the greatest extent.

[0041] According to the specific embodiments provided by the present utility model, based on the foregoing solutions, the first fixing unit 211 and the second fixing unit 212 can be configured with relevant devices for adjusting the fastening relationship between the two. The relevant devices can be provided on the first fixing unit 211 or the second fixing unit 212, or both the first fixing unit 211 and the second fixing unit 212 are provided with the relevant devices. Other structures for fixing and supporting the fixing unit can also be designed, and the relevant devices are provided on other structures.

[0042] As an implementation manner, the structure of other fixing and supporting the fixing unit can be designed as a first support mechanism 23, that is, it is designed that the head fixing assembly 2 further includes a first support mechanism 23, wherein the first support mechanism 23 is connected to the clamping mechanism 21 for supporting the clamping mechanism 21.

[0043] Here, the first support mechanism 23 can be designed to be adapted to the structure of the clamping mechanism 21. When the clamping mechanism 21 is an integral structure, the first support mechanism 23 can be designed as an integral structure to be adapted to the clamping mechanism 21; when the clamping mechanism 21 is a dual-unit design, the first support mechanism 23 can also be designed as an integral structure, or the first support mechanism 23 can be designed as a split structure. Those skilled in the art can design and manufacture according to actual needs, and the present utility model does not make specific limitations.

[0044] When the first support mechanism 23 is of an integral structure and the clamping mechanism 21 is of a dual-unit structure, the first support mechanism 23 can be designed to include a base and two adjusting arms. One end of each of the two adjusting arms is fixed to the base, and the other end is connected to the two fixing units of the clamping mechanism 21.

[0045] When the first support mechanism 23 is of a split structure, the first support mechanism 23 can be designed to include a first support unit 231 having a first fixed end, and the first fixed end is connected to the first fixing unit 211 for supporting and fixing the first fixing unit 211; a second support unit 232 having a second fixed end, and the second fixed end is connected to the second fixing unit 212 for supporting and fixing the second fixing unit 212.

[0046] The split design of the first support mechanism 23 provides a more flexible support solution for the clamping mechanism 21. The first support unit 231 and the second support unit 232 respectively support the first fixing unit 211 and the second fixing unit 212. Such a design not only ensures the independent stability of each fixing unit but also allows them to be adjusted and positioned more precisely according to the actual shape of the patient's head, ensuring that the fixing effect is both stable and personalized.

[0047] Lightweight and high-strength materials can be used to make the first support unit 231 and the second support unit 232, such as aluminum alloy or medical-grade composite materials, to reduce the extra burden on the patient while ensuring sufficient support strength. The fixed end of each support unit can be connected to the corresponding fixing unit by screws, buckles or other medical-grade fixing parts to ensure a firm and reliable connection, and at the same time, it is also convenient for quick installation and adjustment.

[0048] As an implementation manner, based on the foregoing solution, when the first support mechanism 23 includes a first support unit 231 and a second support unit 232, that is, when the structure of other fixed support fixing units includes the first support unit 231 and the second support unit 232, a clamping adjustment module 25 is respectively arranged on the first support unit 231 and the second support unit 232. The clamping adjustment module 25 can adopt a knob or a sliding lock to allow medical staff to finely adjust the clamping force and position according to actual needs, ensure that the head is firmly and comfortably fixed, and avoid excessive compression. In addition, through the double clamping adjustment modules 25 respectively arranged on the first support unit 231 and the second support unit 232, the clamping force of the first fixing unit 211 and the second fixing unit 212 can be finely adjusted at different angles, so that in the event of an unexpected situation during the operation (such as the patient's discomfort or the need to urgently change the body position), medical staff can make appropriate adjustments in a convenient position and angle in a timely manner, protecting the patient's safety while maintaining the coherence and accuracy of the surgical operation, greatly improving the efficiency and continuity of the surgical process; it can also adapt to different body types and surgical requirements, simplify the preoperative preparation process, and save surgical time.

[0049] Reference Figure 1 As shown, the clamping adjustment module 25 can be arranged between the first support unit 231 or the second support unit 232 and the first fixing unit 211 or the second fixing unit 212, and the clamping adjustment module 25 and the first support unit 231 or the second support unit 232 are in an inverted L-shaped structure, so that the first support unit 231 or the second support unit 232 bears the supporting force in the vertical direction, and the clamping adjustment module 25 disperses part of the supporting force in the horizontal direction.

[0050] It should be noted that each clamping adjustment module should be designed to be intuitive and easy to use, so that medical staff can easily operate even when wearing gloves. For example, the knob-type adjustment module can be designed in the form of a large diameter and concave-convex patterns to increase the friction and feel recognition during operation; the sliding lock should ensure clear locking and unlocking indications, as well as a smooth and unobstructed adjustment stroke to ensure rapid adjustment or release even in an emergency. To improve the flexibility and convenience of use, the clamping mechanism 21 can also integrate a quick release mechanism that allows medical staff to quickly release the head fixation in an emergency to ensure the patient's safety. This mechanism can be realized through buttons, levers or other similar devices to ensure simple and fast operation.

[0051] In addition, as the basic framework of the entire head fixation assembly 2, the shape and size of the first support mechanism 23 need to be fully considered in the actual application environment of the operating room to ensure compatibility with other medical devices and not interfere with the smooth progress of the surgical operation.

[0052] When the surgical auxiliary device provided by the present utility model needs to be designed as a device with an independent support function, the first support mechanism 23 can be designed to have a bottom. On this basis, its bottom can be designed to be flat and with anti-slip textures to ensure stable placement on the operating table and avoid any minor movement during the operation. When the surgical auxiliary device provided by the present utility model needs to be designed as a device that needs to cooperate with medical equipment (such as operating beds, operating tables, etc.) to achieve auxiliary functions, a gripper can be designed to be provided on the first support mechanism 23. Based on the foregoing solution, refer to Figure 1 As shown, when the first support mechanism 23 includes a first support unit 231 and a second support unit 232, grippers are respectively provided on the first support unit 231 and the second support unit 232, that is, a first gripper 241 is provided on the first support unit 231; a second gripper 242 is provided on the second support unit 232; the first gripper 241 and / or the second gripper 242 are used to clamp the head fixing assembly 2 on the medical equipment.

[0053] In this way, on the one hand, medical staff can flexibly adjust the relative position between the first support unit 231 and the second support unit 232 according to specific needs, so that the first fixing unit 211 and the second fixing unit 212 connected to these two support units move accordingly, thereby easily achieving precise adjustment of the fixing angle and position of the patient's head, greatly improving the adaptability and flexibility during the operation; on the other hand, the surgical auxiliary device provided by the present utility model is not only applicable to the standard operating room environment, but also can adapt to various complex medical scenarios such as mobile operating carts and emergency surgeries, improving the utilization efficiency of resources and the emergency response ability of surgeries.

[0054] The design of the first gripper 241 and the second gripper 242 can include adjustable buckles, screw fasteners or quick locking mechanisms. These designs enable the surgical auxiliary device to be quickly and firmly installed on the medical equipment, and at the same time facilitate quick disassembly and transfer before and after the operation.

[0055] In order to further improve the adaptability and flexibility of the surgical auxiliary device provided by the present utility model during the operation, the distance between the mandibular lifting part and the head clamping part can be designed to be adjustable. Based on the foregoing solution, in order to achieve the adjustable distance between the mandibular lifting part and the head clamping part, the mandibular support assembly 1 can also be provided with a second support mechanism 11, and a third gripper 13 is also provided on the second support mechanism 11. The third gripper 13 is universal with the first gripper 241 and the second gripper 242. In this way, medical staff can change the distance between the first support mechanism 23 and the second support mechanism 11 according to actual needs, thereby changing the distance between the mandibular lifting part and the head clamping part, and further being able to adapt to different patient body types, improving adaptability and flexibility.

[0056] In addition, a sliding, knob or telescopic structure can be provided on the support mechanism or support unit to enable fine adjustment of the mandibular lifting part and the head clamping part in the height direction, ensuring the best support position and angle for each patient and increasing the comfort and safety during the operation.

[0057] The first gripper 241, the second gripper 242 and the third gripper 13 can also be set to rotate relative to their respective support bodies to adapt to different medical devices. The rotation structure is relatively conventional and can refer to the structure of a selfie stick or a mobile phone stand. The present utility model will not elaborate.

[0058] The present utility model does not specifically limit the structures of the first support unit 231, the second support unit 232 and the second support mechanism 11. Referring to Figure 1 as shown, the first support unit 231, the second support unit 232 and the second support mechanism 11 can all be rod-shaped to reduce their physical occupation around the surgical area and avoid interfering with the surgical field of view or affecting the operating space of surgical instruments.

[0059] In some embodiments, the rod-shaped support unit or support mechanism can be only one or composed of several rods. For example, in some embodiments, the second support mechanism 11 can be designed to include a first support rod 111 in the first direction and a second support rod 112 in the second direction. The first direction and the second direction are arranged crosswise. The first direction can be the vertical direction or the horizontal direction. Correspondingly, the second direction can be the horizontal direction or the vertical direction. When the first direction is the vertical direction, the second support rod 112 provides a support force in the vertical direction, and the first support rod 111 provides a support force in the horizontal direction. One end of the first support rod 111 is connected to one end of the second support rod 112. Here, the connection can be fixed, or it can be designed that the first support rod 111 can rotate relative to the second support rod 112 to adjust different angles of the first support rod 111. When the first direction is the horizontal direction, the relative positional relationship between the first support rod 111 and the second support rod 112 is similar to that when the first direction is the vertical direction. The present utility model will not elaborate specifically.

[0060] To achieve the comfort of mandibular lifting, the mandibular lifting part can also be designed to adopt an ergonomic curve shape to better match the mandibular contour, providing not only support but also reducing the pressure on the tissues around the surgical site. A supporting backing plate can also be provided, and a high-density memory foam 12 is arranged on the supporting backing plate, and the high-density memory foam 12 contacts the patient's mandible. Here, the high-density memory foam 12 can be arranged as a whole at one end of the first support rod 111 away from the second support rod 112, or can be arranged as a module that can rotate relative to the first support rod 111 to meet the needs of different angles, such as Figure 1 shown.

[0061] Since the high-density memory foam 12 can gradually deform according to the shape of the contacted object after being pressed and return to its original state after the pressure is removed. Therefore, when it is applied to the mandibular supporting backing plate, on the one hand, it can closely fit the unique contour of each patient's mandible, providing personalized support, avoiding pressure concentration or sliding caused by improper fixation, thus significantly improving the patient's comfort; on the other hand, because the high-density memory foam 12 is soft and has good pressure distribution characteristics, it can minimize the pressure on the soft tissues and bones in the mandibular area while ensuring stable support, reducing the risk of blood circulation obstruction or skin pressure sores caused by long-term surgery; in addition, although the high-density memory foam 12 is relatively soft, the high-density design ensures that it can still provide sufficient supporting force after deformation to maintain the stable state of the mandible. This design that balances softness and support enables the mandible to be stably maintained in the ideal position even if the patient moves slightly during the operation, which is beneficial to the smooth progress of the operation.

[0062] Based on the above technical solutions, the present utility model also provides a medical system, including a medical device, and a supporting device is arranged on the medical device, and the supporting device is used to support and fix the above-mentioned surgical auxiliary appliance.

[0063] Here, the medical device includes but is not limited to devices capable of performing surgeries such as operating tables, operating beds, and surgical carts. On this basis, the supporting device includes but is not limited to fixing frames, baffles, slide rail systems, etc. on the medical device. The design of these supporting devices aims to ensure that the surgical auxiliary appliance can be stably and quickly installed on the medical device and maintain the necessary stability and positioning accuracy during the operation.

[0064] It should be understood that the present utility model does not limit its application to the detailed structure and arrangement of the components proposed by the present utility model. The present utility model is capable of having other embodiments and can be implemented and carried out in various ways. The foregoing variations and modifications fall within the scope of the present utility model. It should be understood that the present utility model disclosed and defined herein extends to all alternative combinations of two or more separate features mentioned or apparent in the text and / or drawings. All such different combinations constitute multiple alternative aspects of the present utility model. The embodiments described herein illustrate the best mode known for implementing the present utility model and will enable those skilled in the art to utilize the present utility model.
