[0051] See also Figure 3 and Figure 4 As shown, an embodiment of the present application provides a surgical hook structure 100, comprising a hook body 110, a camera module 120, a mounting bracket 130 and a first fixing portion 140; the mounting bracket 130 is connected to the hook body 110; the mounting bracket 130 is provided with a first mounting groove 131 for mounting the camera module 120, and the camera module 120 can be driven by an external force to rotate in the first mounting groove 131; the first fixing portion 140 is connected to the mounting bracket 130; the first fixing portion 140 is used to engage with the camera module 120 to limit the camera module 120 in the first mounting groove 131.

[0052] The above-mentioned surgical retractor structure 100, by arranging the camera module 120 on the retractor body 110, enables the camera module 120 to provide the visual field information of the surgical area while the retractor body 110 pulls and lifts the tissue. By operating the camera module 120 to rotate in the first mounting slot 131, the camera angle of the camera module 120 can be adjusted, and then the visual field of the surgical area can be adjusted to meet the needs of real-time observation of different parts during surgery, and then the doctor can be guided to perform the surgical operation accurately, thereby improving the surgical efficiency. When the retractor structure is applied to cardiac surgery, since the camera module 120 is integrated on the retractor body 110, there is no need to open a surgical incision for the thoracoscope, which is less traumatic and avoids the possibility of interference between the thoracoscope and other surgical instruments, thereby improving the convenience of the surgery.

[0053] See also Figure 3 and Figure 4 As shown, in one embodiment, both sides of the hook body 110 are provided with a slide groove 111, and the mounting bracket 130 is snapped into the slide groove 111 to improve the connection stability between the mounting bracket 130 and the hook body 110, and the hook body 110 can be driven by an external force to move in the slide groove 111. Specifically, the end of the mounting bracket 130 for cooperating with the hook body 110 is provided with a buckle, for example Figure 3In the embodiment shown, the mounting bracket 130 is approximately rectangular in structure, and buckles for engaging with the slide groove 111 are provided at the four corners of the mounting bracket 130, and there is an open slot between two adjacent buckles along the length direction of the hook body 110, which is convenient for operators to take the mounting bracket 130 through the open slot, and can reduce the contact area between the mounting bracket 130 and the hook body 110, thereby reducing the moving resistance. Among them, the buckle has a certain elasticity and a certain hardness, so that the mounting bracket 130 can be engaged in the slide groove 111 through the buckle, thereby fixing the camera module 120 on the hook body 110. At the same time, because the buckle has a certain elasticity, when an external force is applied to the mounting bracket 130, the mounting bracket 130 can slide along the slide groove 111, thereby changing the relative position between the camera module 120 and the hook body 110, and then changing the position of the camera module 120 to meet the camera requirements of different positions.

[0054] See also Figure 3 and Figure 4 As shown, in one embodiment, the first fixing portion 140 is configured with an avoidance hole 141 for exposing the camera module 120. That is to say, the first fixing portion 140 is a hollow structure, so that after fixing the camera module 120, it will not block the camera module 120, thereby ensuring the clarity of the field of view of the surgical area captured. Furthermore, the first fixing portion 140 has a plurality of elastic claws 142 distributed at intervals along its own circumference, and the elastic claws 142 are used to engage with the camera module 120. It can be understood that the accommodation space surrounded by the elastic claws 142 is smaller than the volume of the camera module 120, so that the camera module 120 can be clamped to ensure the fixing effect. By arranging a plurality of elastic claws 142 at intervals, the gaps between adjacent elastic claws 142 provide deformation space for the elastic claws 142, thereby preventing the elastic claws 142 from deforming excessively and affecting their service life. The outer contour of the camera module 120 is designed to be spherical, and a plurality of elastic claws 142 surround a spherical space, which fits and clamps the outer surface of the camera module 120. The first fixing portion 140 and the mounting bracket 130 can be integrally formed, and the first fixing portion 140 protrudes from the upper surface and the lower surface of the mounting bracket 130, thereby increasing the contact area between the first fixing portion 140 and the camera module 120 and improving the fixing effect of the camera module 120.

[0055] See also Figures 6 to 9 As shown, in another embodiment, the inner wall of the first fixing portion 140 is configured with a plurality of elastic protrusions 143 for abutting against the camera module 120. By providing a plurality of elastic protrusions 143, the rotational friction between the first fixing portion 140 and the camera module 120 is reduced, making it easier to rotate the camera module 120 to adjust the angle of the camera module 120.

[0056] See also Figures 6 to 9 As shown, in one embodiment, the mounting bracket 130 includes a first cover 132 and a second cover 133; the first mounting groove 131 is provided on the first cover 132; the first fixing portion 140 is connected to the first cover 132; in the locked state, the second cover 133 is buckled with the first cover 132 to limit the camera module 120 in the first mounting groove 131. In this way, when the camera module 120 needs to be used, the second cover 133 is closed relative to the first cover 132, that is, the mounting bracket 130 is in the locked state, as shown in FIG. Figure 6 As shown, the camera module 120 can be limited between the first cover 132 and the second cover 133. When the camera module 120 needs to be removed, the second cover 133 can be opened relative to the first cover 132, so that the mounting bracket 130 is in an unlocked state, as shown in FIG. Fig. 9 As shown, the camera module 120 can be easily taken out, which is more convenient to use. The first cover 132 and the second cover 133 can be rotatably connected, and the mounting bracket 130 can be opened or locked by opening or closing the second cover 133 relative to the first cover 132. The first cover 132 and the second cover 133 can also be detachably connected. When closing is required, the first cover 132 and the second cover 133 are engaged; when the camera module 120 needs to be taken out, the first cover 132 and the second cover 133 are unengaged.

[0057] See also Figures 6 to 9 As shown, in one embodiment, the second cover 133 is configured with a limiting hole 1331. In the locked state, part of the camera module 120 is engaged with the limiting hole 1331. The cooperation between the limiting hole 1331 and the first fixing portion 140 further improves the fixing effect of the camera module 120. At the same time, part of the camera module 120 protrudes from the limiting hole 1331, so that the protruding part of the camera module 120 can be held to rotate the camera module 120 to adjust its shooting angle.

[0058] See also Figures 6 to 9 As shown, in one embodiment, one of the first cover 132 and the second cover 133 is configured with a first buckle portion 1332, and the other is configured with a first slot 1321 for engaging with the first buckle portion 1332. Fig. 9In the illustrated embodiment, a first buckle portion 1332 is provided on the second cover 133, and a first slot 1321 is provided on the first cover 132. When the mounting bracket 130 is in a locked state, the first buckle portion 1332 is engaged with the first slot 1321. The first buckle portion 1332 has a certain elasticity, so the first buckle portion 1332 can be operated to be disengaged from the first slot 1321, so that the second cover 133 is opened relative to the first cover 132.

[0059] In other embodiments, the positions of the first buckle portion 1332 and the first buckle slot 1321 can be interchanged, that is, the first buckle portion is located on the first cover body, and the first buckle slot is located on the second cover body.

[0060] See also Figures 6 to 9 As shown, specifically, taking the first buckle portion 1332 being located on the second cover 133 and the first slot 1321 being located on the first cover 132 as an example, the first buckle portion 1332 includes a first main body section 1333 and a first bending section 1334 connected to the first main body section 1333; when the mounting bracket 130 is in the locked state, the first main body section 1333 is inserted into the first slot 1321, and the first bending section 1334 abuts against the second cover 133, that is, the first buckle portion 1332 is in the shape of a hook. Through this arrangement, the buckling reliability and stability of the first cover 132 and the second cover 133 are guaranteed. When an external force acts on the first bending section 1334, so that the first bending section 1334 withdraws from the first slot 1321, the second cover 133 will automatically open under the elastic action of the elastic member installed on the rotating shaft 134.

[0061] See also Figures 6 to 9 As shown, in one embodiment, the second cover 133 is configured with a second snap-on portion 1335 at at least one end along its length direction, and the second snap-on portion 1335 is connected to the hook body 110 and can move relative to the hook body 110 under the action of an external force. The second cover 133 can be provided with a second snap-on portion 1335 at both ends to snap with the hook body 110, or only at one end to snap with the hook body 110. Further, the first cover 132 is provided with a third snap-on portion 1322 at at least one end along its length direction, and the third snap-on portion 1322 is connected to the hook body 110 and can move relative to the hook body 110 under the action of an external force. Similarly, the first cover 132 can be provided with a third snap-on portion 1322 at both ends to snap with the hook body 110, or only at one end to snap with the hook body 110.

[0062] Specifically, Figure 8In the illustrated embodiment, the second snap-in portion 1335 is in the shape of a hook, and the second snap-in portion 1335 in the shape of a hook forms a second accommodation space for snapping the hook body 110, that is, at least part of the hook body 110 is located in the second accommodation space, and the second snap-in portion 1335 has a certain elasticity and hardness, so that the mounting bracket 130 can be snapped on the hook body 110 through the second snap-in portion 1335, and the mounting bracket 130 can slide relative to the hook body 110 under the action of an external force. In other embodiments, a slide groove may be provided on the hook body, and the second snap-in portion partially extends into the slide groove to realize the connection between the mounting bracket and the hook body. Further, the structural shape of the third snap-in portion 1322 may refer to the second snap-in portion 1335, and will not be described in detail here.

[0063] See also Figures 6 to 9 As shown, in one embodiment, the second cover body 133 is configured with a second buckle portion 1335 at one end along its own length direction, and is rotatably connected to the first cover body 132 at the other end along its own length direction; when in the locked state, the hook body 110 is clamped between the first cover body 132 and the second cover body 133.

[0064] Specifically, the mounting bracket 130 includes a rotating shaft 134, a first cover 132 and a second cover 133 are respectively located on both sides of the rotating shaft 134 along its own radial direction, and the first cover 132 and the second cover 133 are both configured with a fourth buckle portion 1336, and the fourth buckle portion 1336 is configured with a first accommodating space for clamping the rotating shaft 134; the first cover 132 and the second cover 133 are sleeved at different positions of the rotating shaft 134 through the fourth buckle portion 1336, for example, the second cover 133 is sleeved at the middle position of the rotating shaft 134 through the fourth buckle portion 1336, and the first cover 132 is sleeved at both ends of the rotating shaft 134 through the fourth buckle portions 1336 arranged at both ends of the axial direction of the rotating shaft 134. The first cover 132 or the second cover 133 rotates around the axis of the rotating shaft 134, so as to realize the rotation connection between the first cover 132 and the second cover 133. The hook body 110 is clamped between the first cover 132 and the second cover 133 to achieve the connection between the mounting bracket 130 and the hook body 110. Furthermore, an elastic member is sleeved on the rotating shaft 134, one end of the elastic member abuts against the first cover 132, and the other end abuts against the second cover 133. Figure 6 In the locked state shown, the deformation of the elastic member increases to provide a force for the second cover 133 to return to the open position. The elastic member can be a torsion spring or the like.

[0065] It can be understood that in other embodiments, the first cover body and the second cover body may not be connected by a rotating shaft. The two ends of the first cover body along its length direction are clamped to the hook body through the aforementioned third clamping parts, and the two ends of the second cover body along its length direction are clamped to the hook body through the second clamping parts.

[0066] See also Figures 6 to 9 As shown, in one embodiment, the camera module 120 includes an elastic sleeve portion 127, a camera body portion 121, and a wire portion 126 that is communicatively connected to the camera body portion 121; the elastic sleeve portion 127 is configured with a storage space for accommodating the camera body portion; the camera body portion 121 is installed in the first installation groove 131 through the elastic sleeve portion 127. By providing the elastic sleeve portion 127, the camera module 120 and the first fixing portion 140 are in elastic contact, thereby facilitating the rotation of the camera module 120; at the same time, the elastic sleeve portion 127 can also provide protection for the camera body portion 121 to prevent wear and tear, thereby increasing its service life. The elastic sleeve portion 127 is specifically made of a flexible material such as rubber and has a certain hardness. As Figure 8 As shown, the elastic sleeve portion 127 may be spherical.

[0067] like Fig.10 As shown, in some embodiments, the camera body 121 includes a PCB circuit board 125 and a micro camera 124 welded on the PCB circuit board 125. The viewing angle in the surgical area tissue is obtained through the micro camera 124. Further, the camera module 120 also includes an illumination lamp 123, so that the camera module 120 can also provide the function of an illumination light source, so that the clarity of the surgical area tissue is better, which is convenient for guiding the surgeon and the assistant to perform the surgical operation accurately. The illumination lamp 123 can be an LED lamp. Further, the camera module 120 also includes a protective lens 122, which can allow light to pass through, and can seal the illumination lamp 123 and the micro camera 124 in the camera body 121, thereby improving the sealing effect, and then improving the service life of the camera module 120.

[0068] Among them, the surgical retractor structure 100 is also provided with a functional operation area (not shown) which is communicated with the camera module 120. Through the functional operation area, the brightness of the lighting lamp 123 in the camera body 121 and the optical parameters such as the focus, exposure, and white balance of the micro camera 124 can be adjusted to support doctors in obtaining better image quality.

[0069] By rotating the camera module 120, the camera angle of the surgical area below the hook structure is adjusted, and the field of view of the surgical area is adjusted to meet the need for real-time observation of different parts during surgery, thereby guiding the doctor to perform the surgery accurately and improve the efficiency of the surgery. The mounting bracket can be made of a metal material that can be repeatedly cleaned and disinfected, such as stainless steel. The camera module can be made of a rubber material that is resistant to high-pressure steam sterilization, or it can be made into a disposable product that can be sterilized by EO (ethylene oxide).

[0070] Furthermore, if Figure 1 As shown, an embodiment of the present application also provides a surgical system 10, including a display module 300 and the surgical hook structure 100 as described above, wherein the display module 300 is connected to the camera module 120 for communication. More specifically, the tail end of the wire portion 126 of the camera module 120 can be connected to the display module 300, and the real-time image of the surgical area is transmitted to the display module 300 via the camera module 120. The display module 300 is designed with a screen display area and a function operation area, and the image captured by the camera module 120 can be observed in the screen display area. Through the function operation area, the light brightness of the lighting lamp 123 in the camera body 121, the focus, exposure, white balance and other optical parameters of the micro camera 124 can be adjusted to support doctors to obtain better image quality.

[0071] like Figure 1 As shown, in some embodiments, the surgical system 10 further includes a fixing module 200, and the retractor structure is fixed to the end clamping mechanism of the fixing module 200.
