[0050] See also Figures 2 to 4As shown, a surgical hook structure 100 provided in one embodiment of the present application includes a hook body 110, a camera module 120 and an adjustment mechanism 130; the adjustment mechanism 130 includes an adjustment bracket 131, a first transmission unit 133 and a first rotating member 132 transmission-connected to the first transmission unit 133; the adjustment bracket 131 is connected to the hook body 110; the first transmission unit 133 and the first rotating member 132 are both movably connected to the adjustment bracket 131; the first transmission unit 133 is used to drive the first rotating member 132 to rotate around a first axis, so as to drive the camera module 120 connected to the first rotating member 132 to rotate synchronously. Figure 4 As shown, the direction of the first axis is indicated by an arrow X, wherein the hook body 110 is approximately L-shaped, including an operating end located at the upper left corner and an insertion end located at the lower right corner (the insertion end is also the position where the camera module 120 is set), and the direction of the first axis is also the length direction of the insertion end of the hook body 110, which is parallel to the axial direction of the first rotating member 132.

[0051] 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 operation while the retractor body 110 pulls and lifts the tissue. The first transmission unit 133 drives the first rotating member 132 to rotate, and then drives the camera module 120 connected to the first rotating member 132 to rotate, so that the camera angle of the camera module 120 can be adjusted, so that the visual field of the surgical area is increased, and the need for real-time observation of different parts during the operation is met, and then the surgeon and the assistant can be guided to perform the operation accurately, thereby improving the efficiency of the operation. 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 operation.

[0052] See also Figures 4 to 6As shown, in one embodiment, the first transmission unit 133 includes a first transmission rope 1331 and a first operating member 1332 rotatably connected to the adjustment bracket 131; one end of the first transmission rope 1331 is wound around the first operating member 1332, and the other end of the first transmission rope 1331 is wound around the first rotating member 132, wherein the axial direction of the first operating member 1332 is perpendicular to the axial direction of the first rotating member 132, and the other end of the first transmission rope 1331 is bent and sleeved on the first rotating member 132. In this way, when the first operating member 1332 is rotated, the first operating member 1332 will drive the first transmission rope 1331 to make a circular motion, and then can drive the first rotating member 132 to rotate, so that the camera angle of the camera module 120 connected to the first rotating member 132 changes, meeting the needs of real-time observation of different parts during surgery. Specifically, the first transmission rope 1331 and the first operating member 1332 are frictionally driven, and the first transmission rope 1331 and the first rotating member 132 are also frictionally driven, so that the first operating member 1332 drives the first transmission rope 1331 to move under the action of friction force, and then drives the first rotating member 132 to rotate around the first axis. It can be understood that in other embodiments, the transmission cooperation between the first transmission rope and the first operating member, and the cooperation between the first transmission rope and the first rotating member can also be similar to the meshing transmission of a sprocket and a chain.

[0053] See also Figures 4 to 6 As shown, in a specific embodiment, the first rotating member 132 is fixedly connected with a first transmission wheel 136, and the first transmission rope 1331 is wound around the first transmission wheel 136. Specifically, the first transmission rope 1331 and the first transmission wheel 136 are frictionally driven. It can be understood that the axial direction of the first transmission wheel 136 is parallel to the direction of the first axis, and the first transmission wheel 136 and the first operating member 1332 are respectively located at two ends of the hook body 110 along its own length direction. When the first operating member 1332 is rotated, the first transmission rope 1331 is driven to make a circular motion similar to a synchronous belt, so that the first transmission rope 1331 drives the first transmission wheel 136 to rotate around the first axis. The first transmission rope 1331 drives the first transmission wheel 136 to rotate, and then drives the first rotating member 132 fixedly connected to the first transmission wheel 136 to rotate, thereby adjusting the viewing angle of the camera module 120. The first transmission wheel 136 may be configured with a first wire groove 1361 that is recessed in the radial direction, and part of the first transmission rope 1331 may be accommodated in the first wire groove 1361. By providing the first wire groove 1361, the first transmission rope 1331 may be limited to a certain extent, thereby reducing the possibility of the first transmission rope 1331 being separated from the first transmission wheel 136 during movement, thereby ensuring the reliability of power transmission.

[0054] See also Figures 4 to 6As shown, in one embodiment, the first transmission unit 133 further includes a first guide wheel 134 rotatably connected to the adjustment bracket 131, the first guide wheel 134 is arranged on the transmission path between the first operating member 1332 and the first transmission wheel 136, and the first transmission rope 1331 is frictionally transmitted with the first guide wheel 134. The axial direction of the first guide wheel 134, the axial direction of the first transmission wheel 136 and the axial direction of the first operating member 1332 are perpendicular to each other, and the first guide wheel 134 is used to convert the power of the first transmission rope 1331 along the length direction into the power transmission along the width direction, thereby driving the first transmission wheel 136 to rotate around the length direction of the hook body 110. By providing the first guide wheel 134, the movement of the first transmission rope 1331 is further guided and controlled, and the stability and reliability of the power transmission of the first transmission unit 133 to the first rotating member 132 are improved. The first guide wheel 134 is configured with a receiving groove 1341, and the receiving groove 1341 is used to receive part of the first transmission rope 1331, thereby reducing the possibility of the first transmission rope 1331 detaching from the first guide wheel 134 during movement, thereby ensuring the reliability of power transmission.

[0055] See also Figures 4 to 6 As shown, in one embodiment, the first guide wheels 134 include at least two, and the at least two first guide wheels 134 are arranged at intervals along the radial direction of the first transmission wheel 136. Figure 5 In the illustrated embodiment, two first guide wheels 134 are provided, and the two first guide wheels 134 are spaced apart in the thickness direction of the hook body 110. The first transmission rope 1331 is annular, and the first guide wheel 134 at the upper end is frictionally driven with the first transmission rope 1331 at the upper end, and the first guide wheel 134 at the lower end is frictionally driven with the first transmission rope 1331 at the lower end, and the movement paths of the first transmission rope 1331 at the upper end and the first transmission rope 1331 at the lower end are opposite. By providing at least two first guide wheels 134, the movement of the first transmission rope 1331 is smoother, so as to improve the stability and reliability of the power transmission of the first transmission unit 133 to the first rotating member 132.

[0056] See also Figures 4 to 6 As shown, further, the adjustment bracket 131 is also configured with a first threading groove 1311, and the first threading groove 1311 is used to accommodate part of the first transmission rope 1331. Through this arrangement, on the one hand, the possibility of the first transmission rope 1331 accidentally winding around other components can be reduced; on the other hand, the movement of the first transmission rope 1331 can be limited to a certain extent, thereby ensuring the reliability of power transmission.

[0057] See also Figures 6 to 8As shown, in one embodiment, the adjustment mechanism 130 further includes a second transmission unit 142 and a second rotating member 141 transmission-connected to the second transmission unit 142; the second transmission unit 142 is movably connected to the adjustment bracket 131, and the second rotating member 141 is rotationally connected to the first rotating member 132; the camera module 120 is mounted on the second rotating member 141; the second transmission unit 142 is used to drive the second rotating member 141 to rotate around the second axis to drive the camera module 120 to rotate synchronously, wherein the axial direction of the second rotating member, the second axis and the first axis intersect each other. Figure 5 As shown, the direction of the second axis is indicated by arrow Y, and the direction of the second axis is also the width direction of the insertion end of the hook body, which intersects with the axial direction of the second rotating member.

[0058] The second transmission unit 142 drives the second rotating member 141 to rotate, and then drives the camera module 120 connected to the second rotating member 141 to rotate, so that the camera angle of the camera module 120 can be adjusted, so that the field of view of the surgical area is increased, and the need for real-time observation of different parts during surgery is met, so that the surgeon and the assistant can be guided to perform the surgical operation accurately, and the surgical efficiency is improved. Among them, the second rotating member 141 can be a clamp, and the camera module 120 can be clamped in the clamping groove of the clamp, so that when the second rotating member 141 rotates, the angle of view of the camera module 120 changes.

[0059] See also Figures 6 to 8 As shown, in one embodiment, the second transmission unit 142 includes a second transmission rope 1421 and a second operating member 1422 rotatably connected to the adjustment bracket 131; one end of the second transmission rope 1421 is wound around the second operating member 1422, and the other end is wound around the second rotating member 141, and the axial direction of the second operating member 1422 is perpendicular to the axial direction of the second rotating member 141; the second operating member 1422 is configured to be operably rotatable to drive the second rotating member 141 to rotate through the second transmission rope 1421.

[0060] In this way, when the second operating member 1422 is rotated, the second operating member 1422 will drive the second transmission rope 1421 to make a circular motion, and then drive the second rotating member 141 to rotate, so that the camera angle of the camera module 120 connected to the second rotating member 141 changes, meeting the need for real-time observation of different parts during surgery. Specifically, the second transmission rope 1421 and the second operating member 1422 are friction transmission, and the second transmission rope 1421 and the second rotating member 141 are also friction transmission, so that the second operating member 1422 drives the second transmission rope 1421 to move under the action of friction force, and then drives the second rotating member 141 to rotate around the second axis. It can be understood that in other embodiments, the transmission cooperation between the second transmission rope and the second operating member, and the cooperation between the second transmission rope and the second rotating member can also be similar to the meshing transmission of a sprocket and a chain. Among them, the adjustment bracket 131 can be constructed with a second threading groove 1312 for allowing part of the second transmission rope 1421 to pass through, thereby reducing the possibility of the second transmission rope 1421 being accidentally entangled on other components; at the same time, it can also limit the movement of the second transmission rope 1421 to a certain extent, thereby ensuring the reliability of power transmission.

[0061] See also Figures 6 to 8 As shown, in one embodiment, the first rotating member 132 is fixedly connected to the first connecting shaft 135, and the axial direction of the first connecting shaft 135 is perpendicular to the axial direction of the second rotating member 141; the second rotating member 141 is fixedly connected to the second transmission wheel 144, the second transmission wheel 144 is rotatably connected to the first connecting shaft 135, and the axial direction of the second transmission wheel 144 is parallel to the axial direction of the first connecting shaft 135; the second transmission rope 1421 is annular, the second transmission wheel 144 and the second operating member 1422 are respectively located at the two ends of the hook body 110 along its own length direction, one end of the second transmission rope 1421 is wound around the second operating member 1422, and the other end is wound around the second transmission wheel 144, and the second operating member 1422 drives the second transmission wheel 144 to rotate around the first connecting shaft 135 through the second transmission rope 1421; the axial direction of the first connecting shaft 135 is parallel to the second axis. The second transmission rope 1421 drives the second transmission wheel 144 to rotate, thereby driving the second rotating member 141 fixedly connected to the second transmission wheel 144 to rotate, thereby adjusting the viewing angle of the camera module 120 .

[0062] Specifically, Figure 5As shown, the first rotating member 132 extends outwardly with two connecting arms, and the connecting arms are respectively connected to the first connecting shaft 135. The two sides of the second rotating member 141 are correspondingly provided with connecting holes, and the first connecting shaft 135 is correspondingly penetrated through the connecting holes on the corresponding sides, so as to realize the movable connection between the first rotating member 132 and the second rotating member 141, so as to facilitate the independent rotation control of the first rotating member 132 and the second rotating member 141. At the same time, by clamping the second rotating member 141 in the first rotating member 132, the space occupied by the two can be reduced, making the hook structure more compact. Among them, the second transmission wheel 144 can be designed on one side, that is, the second transmission wheel 144 is fixedly connected only on one side of the second rotating member 141; it can also be symmetrically arranged, that is, the two second transmission wheels 144 are symmetrically connected to the two sides of the second rotating member 141, and the second transmission rope 1421 is frictionally transmitted with one of the second transmission wheels 144. By setting two second transmission wheels 144, the stability of power transmission to the second rotating member 141 is improved, and the reliability of the second rotating member 141 rotating around the second axis is improved. As shown in FIG. Figure 6 As shown, the first transmission rope 1331 and the second transmission rope 1421 are respectively located on both sides of the insertion end of the hook body 110 along the width direction to reduce the possibility of interference between the two during the transmission process, and the layout is more compact and occupies less space.

[0063] The second transmission wheel 144 may be configured with a second wire groove 1441 that is recessed in the radial direction, and part of the second transmission rope 1421 may be accommodated in the second wire groove 1441. By providing the second wire groove 1441, the second transmission rope 1421 may be limited to a certain extent, thereby reducing the possibility of the second transmission rope 1421 being separated from the second transmission wheel 144 during movement, thereby ensuring the reliability of power transmission to the second transmission wheel 144 and the second rotating member 141.

[0064] like Fig. 9 As shown, in some embodiments, the camera module 120 includes a camera body and a wire part 126 that is communicatively connected to the camera body. Among them, the camera body 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 illuminator 123, so that the camera module 120 can also provide the function of an illuminator, 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 illuminator 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 illuminator 123 and the micro camera 124 in the camera body, thereby improving the sealing effect, and then improving the service life of the camera module 120.

[0065] 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 can be adjusted, and the focus, exposure, white balance and other optical parameters of the micro camera 124 can be adjusted to support doctors in obtaining better image quality.

[0066] like Fig.10 As shown, in another embodiment, when the surgical operation space is small and there may not be enough height space to accommodate the camera module 120, the diameter of the camera module 120 can be increased and the height of the camera module 120 can be reduced, such as Fig.10 As shown. In this embodiment, the camera is directly welded to the center of the PCB circuit board 125, the lighting lamp 123 is welded around the camera, and the wire portion 126 is welded to the edge of the PCB circuit board 125. That is, the height of the camera module 120 is reduced by increasing the diameter. As long as the diameter of the camera module 120 does not exceed the width of the hook structure, it will not affect the surgical operation, thereby reducing the need for additional surgical height space and meeting the use requirements in certain special cases.

[0067] By operating the aforementioned first operating member 1332 and the second operating member 1422, the camera module 120 can be rotated in two directions, thereby adjusting the camera angle of the surgical area below the retractor structure, thereby increasing the field of view of the surgical area and meeting the need for real-time observation of different parts during surgery, thereby guiding the surgeon and assistants to perform surgical operations accurately and improving surgical efficiency.

[0068] 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. The function operation area can be used to adjust the light brightness of the lighting lamp 123 in the camera body, and adjust the optical parameters such as the focus, exposure, and white balance of the micro camera 124 to support doctors in obtaining better image quality.

[0069] like Figure 1As 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. By fixing the retractor structure to the fixing module 200, there is no need for a special assistant to pull, so as to free the manual operation of the medical staff, avoid manpower consumption and work fatigue, increase the stability of the use of the retractor structure, and help the smooth and efficient operation. Among them, the fixing module 200 can be clamped and fixed on the side rail of the operating table 400. The fixing module 200 is designed with at least one adjustment joint, through which the position of the end clamping mechanism can be flexibly adjusted, thereby adjusting the position of the retractor structure.

[0070] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0071] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
