Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to a surgical imaging device with adjustable viewing angle and a visual surgical system. Background Art

[0002] Existing medical surgical instruments are mostly used in conjunction with endoscopes for minimally invasive surgery. However, when endoscopes are used in conjunction with surgical instruments, doctors must operate both instruments at the same time, which requires a long learning cycle and is difficult to operate. In addition, the maintenance costs of multiple instruments are high. Therefore, the integration of multiple instruments will be the development trend of surgical medical devices in the future. As the indispensable "eyes" of minimally invasive surgery, the integration of endoscopes with surgical instruments can greatly reduce the comprehensive use cost of instruments, and is also conducive to promoting the disposable use of surgical instruments, avoiding repeated disinfection and sterilization of traditional optical endoscopes, and reducing the risk of cross infection.

[0003] There are generally two types of endoscopic surgery. One is to insert surgical instruments and endoscopes through different holes into the target part of the human body. The second is to insert surgical instruments through the sheath and other parts of the endoscope into the target part of the human body. The first type of endoscopic surgery requires opening multiple holes. The endoscope can change its angle independently, so the field of view is good. Second, independent surgical instruments and endoscopes will take up more space in the human body. The second type of endoscopic surgery requires fewer holes, and the surgical instruments and endoscopes take up less space. These two types of endoscopic surgery have their own advantages and disadvantages, and doctors choose the corresponding hole opening method for different procedures.

[0004] Although an electronic endoscope can be fixed on the front end of the surgical instrument to achieve the fusion of the surgical instrument and the endoscope, the advantage is that the fusion is simple. However, since the electronic endoscope is fixed on the surgical instrument, the viewing angle is single, and it is difficult to obtain the doctor's ideal surgical viewing angle, resulting in an increase in blind spots in the field of vision, increased difficulty of surgery, and even inability to perform normal surgical operations, which cannot truly meet clinical needs. Summary of the invention

[0005] In view of this, the purpose of the present invention is to provide a surgical camera device and a visual surgical system with adjustable viewing angle, which can integrate an electronic mirror and surgical instruments into one.

DETAILED DESCRIPTION

[0050] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0053] Furthermore, the terms “first”, “second”, etc. are merely used for distinguishing descriptions and should not be understood as indicating or implying relative importance.

[0054] Embodiment 1:

[0055] Please refer to Figure 1-Figure 3 As shown, the first embodiment of the present invention provides a surgical camera device 10, which needs to be used in conjunction with surgical instruments (please refer to the second embodiment), and can perform endoscopic surgery for minimally invasive surgery. The surgical camera device 10 can enter the human body through a hole opened in the patient's abdomen, etc., and can play a role in taking pictures, providing doctors with a surgical field of view, so that doctors can adjust the position of surgical instruments in time according to the images transmitted back. In addition, the viewing angle of the surgical camera device 10 can be adjusted, so that the doctor can obtain the best surgical viewing angle, and the operation is more precise.

[0056] First of all, it should be noted that the "front" and "rear" mentioned in this embodiment are determined by the positional relationship with the lesion site, that is, the position close to the lesion site is the "front" and the position far from the lesion site is the "rear". For example, the end inserted into the human body is the front end and the end remaining outside is the rear end; or taking the orientation in the attached figure as an example, Figure 2 In the figure, the left side is "front" and the right side is "rear". The orientation is for reference only and is not an absolute position. Of course, in other embodiments, the "front end" and "rear end" can be replaced by "proximal end", "distal end" and the like.

[0057] Among them, the surgical camera device 10 is mainly composed of a positioning card sleeve 11, a camera component 12 and a control component 13. The camera component 12 and the control component 13 are respectively arranged on the positioning card sleeve 11. The following is a detailed discussion of each component of the surgical camera device 10.

[0058] The positioning sleeve 11 is used to connect with the surgical instrument, so that the surgical camera device 10 and the surgical instrument are fixed or relatively fixed.

[0059] The length of the positioning sleeve 11 can be set as needed. Generally speaking, its length should be roughly equal to the rod-shaped part of the surgical instrument, and can be slightly longer or shorter. Generally speaking, the front end of the rod-shaped part of the surgical instrument needs to extend from the front end of the positioning sleeve 11.

[0060] The style of the positioning sleeve 11 and the way it is connected to the surgical instrument are not limited. For example, the positioning sleeve 11 can be a tubular structure such as a round tube or a square tube, or the cross-sections of the positioning sleeve 11 are C-shaped with an arc shape, or the front and rear ends of the positioning sleeve 11 are tubular and the middle part is sheet-shaped or rod-shaped. In this embodiment, the structure of the positioning sleeve 11 can adopt but is not limited to the following schemes: Figure 3-Figure 5 As shown, the positioning sleeve 11 includes a tubular portion 110, a connecting strip 111 and a C-shaped portion 112. In the direction from back to front, the tubular portion 110, the connecting strip 111 and the C-shaped portion 112 are arranged in sequence.

[0061] The tubular portion 110 is a tubular structure, such as a round tube, a square tube, an irregular tube, etc. The rod-shaped portion of the surgical instrument can be inserted into the tubular portion 110. The length of the tubular portion 110 can be long or short and can be set as needed.

[0062] The connecting strip 111 is in the shape of a long strip, and the cross section of the connecting strip 111 can be rectangular, arc-shaped, irregular, etc. Its main function is to connect the tubular portion 110 and the C-shaped portion 112. The width and thickness of the connecting strip 111 are not limited as long as it can ensure that it is not easy to break. In this embodiment, the cross section of the connecting strip 111 is a bad arc shape, and the center angle of the bad arc shape can be set as needed, such as 5°, 10°, 20°, etc., so that the size and weight of the positioning sleeve 11 can be reduced.

[0063] The length of the C-shaped portion 112 is not limited and can be long or short and can be set as needed. The cross-section of the C-shaped portion 112 is C-shaped, such as an arc shape, a door shape, or a rectangle with an open side, etc. The C-shaped portion 112 is mainly used to clamp the front end of the surgical instrument to fix the surgical instrument.

[0064] The C-shaped portion 112 may have a certain elasticity and may be capable of elastic deformation. Generally speaking, the opening width of the C-shaped portion 112 is slightly smaller than the diameter of the rod-shaped portion of the surgical instrument. When a certain pressure is applied, the tubular structure may be inserted into or detached from the C-shaped portion 112.

[0065] The tubular portion 110, the connecting strip 111 and the C-shaped portion 112 of the positioning sleeve 11 can be separately provided and fixed by other means such as welding, clamping, etc. Of course, the tubular portion 110, the connecting strip 111 and the C-shaped portion 112 can also be regarded as an integral structure formed by removing part of the structure of a tube. The reason for making a special design of the connecting strip 111 and the C-shaped portion 112 is that the size and weight of the positioning sleeve 11 can be minimized.

[0066] The camera assembly 12 is arranged outside the front end of the positioning sleeve 11 and is used for lighting, video, etc. It can provide the doctor with a surgical field of view, making it easier for the doctor to observe and adjust the surgical instruments. Figure 6-Figure 9 As shown, the camera assembly 12 includes a slide 120 and an electronic mirror 121 , and the electronic mirror 121 is disposed on the slide 120 .

[0067] The shape and structure of the slide 120 are not limited, and can be a block structure, a frame structure, a plate structure, etc. The slide 120 is located on the outside of the positioning sleeve 11, and the slide 120 is slidably matched with the front end of the positioning sleeve 11, that is, the slide 120 can slide relative to the positioning sleeve 11 in the front-to-back direction. The connection method between the slide 120 and the positioning sleeve 11 is not limited. For example, the positioning sleeve 11 is provided with a guide rod, and the guide rod extends in the front-to-back direction. The slide 120 is provided with a through hole, and the guide rod is penetrated in the through hole, so that the slide 120 can slide along the guide rod. In this embodiment, please combine Figure 8 As shown, the inner side of the slide 120 is an arc, i.e., a cylindrical surface, and the slide 120 fits the outer side of the positioning sleeve 11. The slide 120 and the positioning sleeve 11 are provided with anti-slip sliders 124 and anti-slip grooves 125, respectively. The slide 120 may be provided with an anti-slip slider 124 and the positioning sleeve 11 may be provided with an anti-slip groove 125, or the slide 120 may be provided with an anti-slip groove 125 and the positioning sleeve 11 may be provided with an anti-slip slider 124. Both the anti-slip slider 124 and the anti-slip groove 125 extend in the front-to-back direction, i.e., the axial direction of the positioning sleeve 11, and the anti-slip slider 124 can slide forward and backward along the anti-slip groove 125.

[0068] The number of the anti-slip slider 124 and the anti-slip groove 125 is not limited, for example, one, two, three, etc. Preferably, the number of the anti-slip slider 124 and the anti-slip groove 125 is two, and the two anti-slip sliders 124 present a certain angle around the center of the C-shaped portion 112, and the angle size is not limited, for example, 20°, 30°, 40°, etc., as long as it can be ensured that after the two pairs of anti-slip sliders 124 and the anti-slip groove 125 are matched, the slide 120 is not easy to be separated from the positioning sleeve 11. The cross-sectional shape of the anti-slip slider 124 and the anti-slip groove 125 can be rectangular, arc-shaped, triangular, etc.

[0069] The electronic mirror 121 is hinged to the slide 120, and the hinge axis of the two can be perpendicular or substantially perpendicular to the front-to-back direction. For example, the hinge axis of the electronic mirror 121 and the slide 120 extends along the radial direction of the positioning sleeve 11. Of course, it is also possible that the angle between the two is less than 90°. The electronic mirror 121 can rotate around the hinge axis of the two, so that the electronic mirror 121 can swing left and right relative to the front-to-back direction, that is, the angle between the center line of the viewing angle of the electronic mirror 121 and the front-to-back direction changes, so as to observe the environment in the left front or right front. The maximum swing angle of the electronic mirror 121 is not limited, for example, 30°, 45°, 60°, etc.

[0070] The electronic mirror 121 and the slide 120 may be directly hinged or indirectly hinged through other structures. In the present embodiment, the electronic mirror 121 and the slide 120 are indirectly hinged. Specifically, the camera assembly 12 further includes an L-shaped member 122. The L-shaped member 122 has a first end, a second end, and a middle portion. The middle portion may be regarded as a corner or a place close to a corner. The first end of the L-shaped member 122 is fixed to the electronic mirror 121, and the second end or the middle portion is hinged to the slide 120. Of course, it is also possible to form the L-shaped member 122 and the electronic mirror 121 as one piece, or to regard the L-shaped member 122 as a part of the electronic mirror 121.

[0071] In other embodiments, the L-row pieces may also be replaced with other styles, such as V-shaped pieces, rectangular blocks, circular pieces, etc.

[0072] The control component 13 is used to adjust the position and viewing angle of the camera component 12, so that the doctor can obtain the best surgical viewing angle and make the surgery more precise.

[0073] The control component 13 is used to control the sliding seat 120 to slide forward and backward, and to control the electronic mirror 121 to swing left and right. When the control component 13 controls the sliding seat 120 to slide forward and backward, the distance between the front end of the electronic mirror 121 and the lesion site can be adjusted, so that the lesion site can be observed closely, or the surrounding situation can be observed far away from the lesion site; when the control component 13 controls the electronic mirror 121 to swing left and right, the left and right viewing angles at the same position can be adjusted, so that the lesion site directly in front of the front end of the surgical instrument, obliquely in front of or on both sides can be observed. The doctor can adjust the field of view in time according to actual needs to facilitate the smooth progress of the operation.

[0074] The structure of the control assembly 13 is not limited, and can be manual control or electric control. Generally speaking, manual control can reduce parts as much as possible. In the present embodiment, the control assembly 13 includes a front push member 130 and a swing member 131, and the front push member 130 and the swing member 131 extend in the front-rear direction.

[0075] The length of the front push piece 130 and the rocking piece 131 can be set as needed. Generally speaking, the length of the front push piece 130 and the rocking piece 131 will be less than the length of the positioning sleeve 11, but the difference between the two will not be too large. It is necessary to ensure that the rear ends of the front push piece 130 and the rocking piece 131 are adjacent to the rear end of the positioning sleeve 11, so that medical staff can operate and control. Of course, in other embodiments, the length of the front push piece 130 and the rocking piece 131 is greater than the length of the positioning sleeve 11, or the length of one of the front push piece 130 and the rocking piece 131 is greater than the length of the positioning sleeve 11 and the other is less than the length of the positioning sleeve 11.

[0076] The front end of the forward push piece 130 is connected to the sliding seat 120, and the two can be directly connected or indirectly connected, and the connection method between the two is not limited, such as one-piece molding, bonding, welding, connection through threaded fasteners, etc. When the doctor controls the forward push piece 130 to move forward and backward, it can push the sliding seat 120 to slide forward and backward.

[0077] The front push piece 130 can be tubular, rod-shaped, semi-tubular, etc. In this embodiment, the front push piece 130 is semi-tubular, and its cross section is C-shaped. The interior of the front push piece 130 is hollow, and the open side of the front push piece 130 cooperates with the positioning sleeve 11 to form a wiring pipeline. Figure 4 As shown, the wire 123 can pass through the wiring pipeline to connect with the electronic mirror 121 to achieve functions such as power supply and signal transmission.

[0078] The front end of the rocking member 131 is hinged to the electronic mirror 121, and the two can be directly connected or indirectly connected. In the present embodiment, the electronic mirror 121 and the rocking member 131 are indirectly hinged through the L-shaped member 122, and the rocking member 131 is hinged to the second end or the middle of the L-shaped member 122. The hinge axis between the L-shaped member 122 and the slide 120 is the first hinge axis, and the hinge axis between the L-shaped member 122 and the rocking member 131 is the second hinge axis, and the first hinge axis and the second hinge axis are parallel or substantially parallel. Of course, in other embodiments, it is also possible to set the first hinge axis and the second hinge axis at an angle, and the size of the angle can be selected according to actual needs, such as 5°, 10°, etc. When the rocking member 131 moves back and forth, it can drive the electronic mirror 121 to rotate around the first hinge axis, so that the electronic mirror 121 can swing left and right.

[0079] There is no limit to the control method of the front push member 130 and the rocking member 131. For example: a front push seat is provided at the rear end of the front push member 130, and a first slider and a first slide groove are correspondingly provided at the front push seat and the rear end of the positioning sleeve 11. The first slider slides in cooperation with the first slide groove, and the medical staff can push the front push seat to move, thereby controlling the front push member 130 to move forward or backward; a rocking seat is provided at the rear end of the rocking member 131, and a second slider and a second slide groove are correspondingly provided at the rocking seat and the limit seat, and the second slider slides in cooperation with the second slide groove, and the medical staff can push the rocking seat to move while keeping the front push seat stationary, thereby controlling the rocking member 131 to move forward or backward; when the camera assembly 12 needs to slide back and forth, the medical staff only needs to push the limit seat to slide back and forth; when the electronic mirror 121 needs to swing left and right, it is only necessary to keep the limit seat stationary and then push the rocking seat to slide back and forth. Of course, in other embodiments, the first slider and the first slide groove may be replaced by a guide rod and a guide block, or the cooperation mode of the first slider and the second slide groove may be replaced by the rear end of the rocking member 131 and the limit seat being cooperated by the rocking rod, etc. In other embodiments, the rear ends of the forward push member 130 and the rocking member 131 may not be connected to the positioning sleeve 11, but may be directly manually maintained and controlled by the doctor.

[0080] In this embodiment, the control method of the forward push member 130 and the swing member 131 can be adopted but not limited to the following schemes: Figure 2 , Figure 3As shown, the control component 13 also includes a first component 140 and a second component 150, which are located at the rear end of the positioning card sleeve 11, and the first component 140 and the second component 150 are used to control the forward and backward movement of the front push member 130 and the swing member 131, so as to realize the forward and backward movement of the camera assembly 12 and the left and right swing of the electronic mirror 121. Among them, the first component 140 is connected to the front push member 130 and is used to push the swing member 131 to move forward and backward, and the second component 150 is connected to the positioning card sleeve 11 and is used to push the first component 140 and the camera assembly 12 to move forward and backward. Of course, the swing seat can also be regarded as the first component 140, and the front push seat can be regarded as the second component 150.

[0081] The first component 140 can be located in front of the second component 150 or behind the second component 150. The structures of the first component 140 and the second component 150 are not limited, and the following solutions can be adopted but are not limited to: Figure 5 As shown, the first component 140 can be located in front of the second component 150, and both the first component 140 and the second component 150 include a positioning cylinder, a push sleeve and a rotating cylinder. For the convenience of description, the following definitions are made: the first component 140 includes a first positioning cylinder 141, a first push sleeve 142 and a first rotating cylinder 143, and the second component 150 includes a second positioning cylinder 151, a second push sleeve 152 and a second rotating cylinder 153, wherein the structures between the first positioning cylinder 141 and the second positioning cylinder 151, between the first push sleeve 142 and the second push sleeve 152, and between the first rotating cylinder 143 and the second rotating cylinder 153 can be the same or different.

[0082] Please combine Fig.10 , Fig.11 As shown, the positioning cylinder is a cylindrical or tubular structure, such as a round tube, a square tube, an irregular tube, etc., and its interior is hollow. The first positioning cylinder 141 is connected to the front push piece 130, and the second positioning cylinder 151 is connected to the positioning sleeve 11. The positioning sleeve 11 passes through the first positioning cylinder 141 and the second positioning cylinder 151 in sequence. The fixing method of the first positioning cylinder 141 and the front push piece 130, and the fixing method of the second positioning cylinder 151 and the positioning sleeve 11 is not limited, and can be sleeve connection, bonding, etc.

[0083] Please combine Fig.12As shown, the shape of the push sleeve is not limited, and the push sleeve is cylindrical or tubular, such as a round tube, a square tube, an irregular tube, etc. The shape of the push sleeve can match the positioning tube. In this embodiment, the first push sleeve 142 is sleeved on the first positioning tube 141, and the first push sleeve 142 can slide forward and backward along the first positioning tube 141, but the first push sleeve 142 cannot rotate around the center line of the first positioning tube 141. The structure that can achieve this effect is not limited. For example, if the rear ends of the first push sleeve 142 and the first positioning tube 141 are both square tubes, the two themselves cannot rotate relative to each other. If the first push sleeve 142 and the first positioning tube 141 are both round tubes, it is necessary to add a circumferential limiting structure to limit the first push sleeve 142 circumferentially to ensure that the first push sleeve 142 can only slide forward and backward along the first positioning tube 141 and cannot rotate around the first positioning tube 141. The second push sleeve 152 is sleeved on the second positioning tube 151, and the second push sleeve 152 can slide forward and backward along the second positioning tube 151, but the second push sleeve 152 cannot rotate around the center line of the second positioning tube 151. The structures of the two can refer to the connection relationship between the first push sleeve 142 and the first positioning tube 141. In addition, the front end of the second push sleeve 152 is connected and fixed to the first positioning tube 141.

[0084] The circumferential limiting structure between the push sleeve and the positioning sleeve is not limited. In the present embodiment, a first axial sliding groove 144 is provided on the first positioning sleeve 141, and a first movable part 145 is provided on the first push sleeve 142. The first movable part 145 is embedded in the first axial sliding groove 144 and can circumferentially limit the first push sleeve 142; a second axial sliding groove 154 is provided on the second positioning sleeve 151, and a second movable part 155 is provided on the second push sleeve 152. The second movable part 155 is embedded in the second axial sliding groove 154 and can circumferentially limit the second push sleeve 152.

[0086] The rotating drum is rotatably sleeved on the positioning drum, and the rotating drum can only rotate around the center line of the positioning drum, but cannot slide forward and backward relative to the positioning drum. The connection method between the two is not limited, for example: in this embodiment, the outer side of the first positioning drum 141 is provided with a circumferential first raised ring 148, and the inner side of the first rotating drum 143 is provided with a circumferential first recessed groove, and the first raised ring 148 is embedded in the first recessed groove, and the first raised ring 148 and the first recessed groove are slidably matched. The setting method of the first recessed groove is not limited, for example, the rear end of the first rotating drum 143 includes a first main body 146 and a first blocking ring 147, and the inner side of the first main body 146 is provided with at least three levels of stepped holes, which are divided into large holes, middle holes, and small holes according to the diameter, and the first blocking ring 147 is provided at the large hole of the stepped hole, and the first blocking ring 147 and the side wall end of the small hole limit the first raised ring 148 at the middle hole of the stepped hole. The first sealing ring 147 can be removed from the first rotating cylinder 143 , so that the first protruding ring 148 can be disengaged from the first rotating cylinder 143 , which facilitates the installation and disassembly of the first rotating cylinder 143 and the first positioning cylinder 141 .

[0087] Similarly, a circumferential second raised ring 158 is provided on the outer side of the second positioning cylinder 151, and a circumferential second recessed groove is provided on the inner side of the second rotating cylinder 153. The second raised ring 158 is embedded in the second recessed groove, and the second raised ring 158 and the second recessed groove are slidably fitted together. The rear end of the second rotating cylinder 153 includes a second main body 156 and a second sealing ring 157.

[0088] In other embodiments, other solutions may be used instead. For example, the raised ring may be replaced by a plurality of raised portions, and the plurality of raised portions are distributed around the circumference of the positioning tube.

[0089] The rotary cylinder and the push sleeve are threadedly engaged. Specifically, in this embodiment, part or all of the first push sleeve 142 is located in the first rotary cylinder 143, the inner surface of the first rotary cylinder 143 is provided with an internal thread, the outer surface of the first push sleeve 142 is provided with an external thread, and the internal thread is threadedly engaged with the external thread. When the first rotary cylinder 143 rotates, the first push sleeve 142 can be pushed to slide forward and backward under the cooperation of the internal thread and the external thread; part or all of the second push sleeve 152 is located in the second rotary cylinder 153, the inner surface of the second rotary cylinder 153 is provided with an internal thread, the outer surface of the second push sleeve 152 is provided with an external thread, and the internal thread is threadedly engaged with the external thread. When the second rotary cylinder 153 rotates, the second push sleeve 152 can be pushed to slide forward and backward under the cooperation of the internal thread and the external thread.

[0090] The first push sleeve 142 is connected to the rocking member 131, and the second push sleeve 152 is connected to the first positioning cylinder 141. When the first rotating cylinder 143 is rotated, the first push sleeve 142 can slide forward and backward, thereby pushing the rocking member 131 to move forward and backward; when the second rotating cylinder 153 is rotated, the second push sleeve 152 can slide forward and backward, thereby pushing the first assembly 140 to move forward and backward as a whole, that is, the front pushing member 130, the rocking member 131 and the camera assembly 12 move forward and backward at the same time.

[0091] The second assembly 150 is provided with a locking bolt 159, and the position of the locking bolt 159 is not limited. For example, the second positioning cylinder 151 is provided with a through hole, and the locking bolt 159 is passed through the through hole and the two are threadedly engaged. The locking bolt 159 is used to be pressed and fixed with the surgical instrument. Of course, in other embodiments, the second assembly 150 and the surgical instrument can also be fixed in other ways, such as bonding, clamping, etc.

[0092] The method of using the surgical imaging device 10 with adjustable viewing angle provided in this embodiment is as follows:

[0093] Please combine Fig.13 As shown, when the camera assembly 12 needs to be moved closer to or away from the lesion, that is, when the camera assembly 12 needs to be moved forward and backward, the doctor grasps the positioning sleeve 11 or the second positioning cylinder 151 to keep the positioning sleeve 11 stationary; rotates the second rotating cylinder 153, and the second rotating cylinder 153 drives the second push sleeve 152 to slide forward and backward, and the second ball and the second axial groove 154 limit the circumferential movement of the second push sleeve 152; the second push sleeve 152 drives the first positioning cylinder 141 to move forward and backward, that is, the first assembly 140 moves forward and backward as a whole, and the first assembly 140 pushes the camera assembly 12 to move forward and backward through the front push piece 130.

[0094] Please combine Figure 14-17 As shown, when the viewing angle needs to be changed, that is, when the electronic mirror 121 needs to be swung left and right, the positioning sleeve 11 or the second positioning cylinder 151 is grasped to keep the positioning sleeve 11 stationary and the second component 150 also remains stationary; the first rotating cylinder 143 is rotated, and the first rotating cylinder 143 drives the first pushing sleeve 142 to slide back and forth. At this time, since the front pushing member 130 is connected to the first positioning cylinder 141 and remains stationary, the first pushing sleeve 142 drives the swinging member 131 to move back and forth, thereby causing the electronic mirror 121 to rotate around the first hinge axis, thereby realizing the left and right swing of the electronic mirror 121.

[0095] The above steps can be increased, decreased, modified, and the order can be adjusted as needed. For example, if there is no first component 140 and the second component 150, and a front push seat and a swing seat are used instead, the front push seat and the swing seat can be manually pushed to slide back and forth to achieve the overall forward and backward movement of the front push member 130 and the swing member 131; the swing seat can be manually pushed to slide back and forth to achieve the front push member 130 being stationary and the swing member 131 moving back and forth.

The connection method of the surgical instrument 20 and the surgical camera 10 is not limited, and needs to be installed according to the specific structure of the surgical camera 10. For example, in this embodiment, the rod-shaped part of the surgical instrument 20 is inserted from the tubular part 110 of the positioning sleeve 11 and extends to the C-shaped part 112. In addition, the front end of the surgical instrument 20, such as the electrode head, the planer head, or the grinder head, is embedded in the C-shaped part 112 and fixed. Generally speaking, the front end of the surgical instrument 20 is more forward relative to the surgical camera 10. When the surgical instrument 20 is inserted into place, the surgical instrument 20 and the surgical camera 10 can be locked by the locking bolt 159.

[0101] In other embodiments, if the positioning sleeve 11 is a tubular structure, the rod-shaped portion of the surgical instrument 20 is inserted from the rear end of the positioning sleeve 11 , and the front end of the surgical instrument 20 extends from the front end of the positioning sleeve 11 .

[0102] The surgical instrument 20 is used to perform preset surgical operations, such as using a radiofrequency ablation electrode to ablate and stop bleeding at the lesion site, a planer instrument to plan the lesion site, and a sharpener to grind the lesion site such as bones; during this process, the surgical camera device 10 can automatically adjust the surgical viewing angle as needed, so that medical staff can clearly observe the operation at the front end of the surgical instrument 20, which is convenient for adjustment.
