Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, specifically relating to a medical power device. Background Technology
[0002] Current surgical instruments are mostly used in minimally invasive surgeries, often in conjunction with endoscopes. However, using endoscopes and surgical instruments together requires surgeons to operate both instruments simultaneously, resulting in a long learning curve and high operational difficulty. Furthermore, the maintenance costs of multiple instruments are high. Therefore, the future trend in surgical medical device development is the integration of multiple instruments. As an indispensable "eye" in minimally invasive surgery, the integration of endoscopes with surgical instruments can significantly reduce the overall cost of instrument use. It also facilitates the use of disposable surgical instruments, avoiding the repeated sterilization of traditional optical endoscopes and reducing the risk of cross-infection.
[0003] Endoscopic surgery generally falls into two categories: one involves inserting surgical instruments and the endoscope into the target area of the body through separate openings; the other involves inserting surgical instruments through the endoscope sheath and other components. The first type of endoscopic surgery requires multiple openings, allowing for better visualization as the endoscope can be adjusted independently; however, the separate surgical instruments and endoscope occupy more space within the body. The second type requires fewer openings, resulting in less space occupied by the instruments and endoscope. Each type of endoscopic surgery has its advantages and disadvantages, and surgeons choose the appropriate opening method based on the specific surgical procedure.
[0004] Although an electronic endoscope can be fixed to the front end of the surgical instrument to achieve fusion of the surgical instrument and the endoscope, the advantage is that the fusion is simple. However, the disadvantage is that the electronic endoscope fixed to the surgical instrument results in a single field of view, making it difficult to obtain the surgeon's ideal surgical view, increasing the blind spot, increasing the difficulty of the operation, and even making it impossible to perform the operation normally, thus failing to truly meet clinical needs. Utility Model Content
[0005] Therefore, the purpose of this utility model is to provide a medical power device that can integrate a camera mechanism and surgical instruments into a whole, reduce the number of surgical openings, and facilitate patient recovery.

Detailed Implementation
[0044] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0045] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0046] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0047] Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.
[0048] Please refer to Figure 1 , Figure 2As shown, Embodiment 2 of the present invention provides a medical power device 100, which can be used for endoscopic surgery and minimally invasive surgery.
[0049] First, it should be noted that the terms "anterior" and "posterior" in this embodiment are determined by their positional relationship to the lesion site; that is, the position closer to the lesion site is "anterior," and the position farther from the lesion site is "posterior." For example, the end inserted into the human body is the anterior end, and the end remaining outside is the posterior end; or, using the orientation shown in the attached diagram as an example... Figure 4 In the diagram, the left side is "front" and the right side is "rear". These positions are for reference only and are not absolute. Of course, in other embodiments, "front end" and "rear end" can be replaced with "near end", "far end", etc.
[0050] The medical power device 100 includes a surgical instrument 20 and a camera mechanism 10, with the surgical instrument 20 installed inside the camera mechanism 10.
[0051] The camera mechanism 10 and surgical instruments 20 can enter the human body through openings made in the patient's abdomen, etc. The camera mechanism 10 can act as a camera, providing the doctor with a surgical field of view, enabling the doctor to adjust the position of the surgical instruments 20 in a timely manner based on the transmitted images; the surgical instruments 20 can perform corresponding functions, such as radiofrequency ablation, shaving, grinding, etc.
[0052] The camera mechanism 10 mainly consists of a positioning sleeve 11, an electronic mirror 12, and a control component 13. The electronic mirror 12 and the control component 13 are respectively disposed on the positioning sleeve 11. Of course, in some embodiments, the camera mechanism 10 may not include the control component 13. The following is a detailed discussion of each component of the camera mechanism 10.
[0053] The positioning sleeve 11 is used to connect with the surgical instrument 20, thereby fixing or relatively fixing the camera mechanism 10 and the surgical instrument 20.
[0054] The length of the positioning sleeve 11 can be set as needed. Generally, its length should be approximately equal to the rod-shaped part of the surgical instrument 20, but it can be slightly longer or shorter. Generally, the front end of the rod-shaped part of the surgical instrument 20 needs to extend from the front end of the positioning sleeve 11.
[0055] The style of the positioning sleeve 11 and its connection method with the surgical instrument 20 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-section of the positioning sleeve 11 can be a C-shape with a superior arc, or the front and rear ends of the positioning sleeve 11 can be tubular and the middle part can be plate-shaped or rod-shaped, etc. In this embodiment, the structure of the positioning sleeve 11 can adopt, but is not limited to, the following schemes: Please refer to... Figures 5-7As shown, the positioning sleeve 11 includes a tubular portion 110, a connecting strip 111, and a C-shaped portion 112, which are arranged sequentially in a back-to-forward direction.
[0056] The tubular part 110 is a tubular structure, such as a round tube, a square tube, or an irregularly shaped tube. The rod-shaped part of the surgical instrument 20 can be inserted into the tubular part 110. The length of the tubular part 110 can be long or short and can be set as needed.
[0057] The connecting strip 111 is elongated and its cross-section can be rectangular, arc-shaped, irregular, etc. Its main function is to connect the tubular part 110 and the C-shaped part 112. The width and thickness of the connecting strip 111 are not limited, as long as they are designed to prevent breakage. In this embodiment, the cross-section of the connecting strip 111 is a minor arc shape, and the central angle of the minor arc can be set as needed, such as 5°, 10°, 20°, etc. This design reduces the size and weight of the positioning sleeve 11.
[0058] The length of the C-shaped part 112 is unlimited and can be long or short as needed. The cross-section of the C-shaped part 112 is C-shaped, such as an arc shape, a gate shape, or a rectangle with an opening on one side. The C-shaped part 112 is mainly used to hold the front end of the surgical instrument 20, thereby fixing the surgical instrument 20.
[0059] The C-shaped portion 112 can have a certain degree of elasticity and be able to undergo 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 20. Under a certain pressure, the tubular structure can be inserted into or detached from the C-shaped portion 112.
[0060] The tubular portion 110, connecting strip 111, and C-shaped portion 112 of the positioning sleeve 11 can be separately configured and fixed by other methods such as welding or snap-fitting. Of course, the tubular portion 110, connecting strip 111, and C-shaped portion 112 can also be regarded as an integral structure formed by removing part of the structure from a tube. The reason for the special design of the connecting strip 111 and C-shaped portion 112 is to minimize the size and weight of the positioning sleeve 11.
[0061] The electronic endoscope 12 is positioned on the outer front end of the positioning sleeve 11. The connection method between the electronic endoscope 12 and the positioning sleeve 11 is not limited. The electronic endoscope 12 is used for illumination, imaging, etc., providing the surgeon with a surgical field of view, facilitating observation and adjustment of the surgical instruments 20. Furthermore, the electronic endoscope 12 can alter the surgical field of view. Please refer to... Figures 8-11 As shown, the electron mirror 12 includes a slide 120 and an electron mirror 121, with the electron mirror 121 disposed on the slide 120.
[0062] The shape and structure of the slide 120 are not limited; it can be a block structure, a frame structure, a plate structure, etc. The slide 120 is located outside the positioning sleeve 11, and the slide 120 slides in slidable engagement with the front end of the positioning sleeve 11, meaning the slide 120 can slide relative to the positioning sleeve 11 in the front-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 extending in the front-back direction, and the slide 120 is provided with a through hole, through which the guide rod passes, allowing the slide 120 to slide along the guide rod. In this embodiment, please refer to... Figure 10 As shown, the inner side of the slide 120 is arc-shaped, i.e., cylindrical. The slide 120 fits against the outer side of the positioning sleeve 11. The slide 120 and the positioning sleeve 11 are respectively provided with anti-detachment sliders 124 and anti-detachment grooves 125. Either the slide 120 is provided with an anti-detachment slider 124 and the positioning sleeve 11 is provided with an anti-detachment groove 125, or the slide 120 is provided with an anti-detachment groove 125 and the positioning sleeve 11 is provided with an anti-detachment slider 124. Both the anti-detachment slider 124 and the anti-detachment groove 125 extend along the front-back direction, i.e., the axial direction of the positioning sleeve 11. The anti-detachment slider 124 can slide back and forth along the anti-detachment groove 125.
[0063] The number of anti-detachment sliders 124 and anti-detachment grooves 125 is unlimited, for example, one, two, or three each. Preferably, there are two anti-detachment sliders 124 and two anti-detachment grooves 125. The two anti-detachment sliders 124 are arranged at a certain angle around the center of the C-shaped part 112. The angle is not limited, for example, 20°, 30°, or 40°, as long as it can be ensured that the slide block 120 is not easily disengaged from the positioning sleeve 11 after the two pairs of anti-detachment sliders 124 and anti-detachment grooves 125 are engaged. The cross-sectional shape of the anti-detachment sliders 124 and anti-detachment grooves 125 can be rectangular, arc-shaped, triangular, etc.
[0064] The electron mirror 121 is hinged to the slide 120. The hinge axis between the two can be perpendicular or substantially perpendicular to the front-back direction. For example, the hinge axis between the electron mirror 121 and the slide 120 extends radially along the positioning sleeve 11. Of course, the included angle between the two can also be less than 90°. The electron mirror 121 can rotate around the hinge axis, thereby causing the electron mirror 121 to swing left and right relative to the front-back direction. That is, the angle between the center line of the viewing angle of the electron mirror 121 and the front-back direction changes, thereby observing the environment to the left front or right front. The maximum swing angle of the electron mirror 121 is unlimited, such as 30°, 45°, 60°, etc.
[0065] The electron mirror 121 and the slide 120 can be directly hinged or indirectly hinged through other structures. In this embodiment, the electron mirror 121 and the slide 120 are indirectly hinged. Specifically, the electron mirror 121 also includes an L-shaped member 122, which has a first end, a second end, and a middle portion. The middle portion can be considered as a corner or near a corner. The first end of the L-shaped member 122 is fixed to the electron mirror 121, and the second end or the middle portion is hinged to the slide 120. Of course, it is also possible to integrally form the L-shaped member 122 and the electron mirror 121, or to consider the L-shaped member 122 as part of the electron mirror 121.
[0066] In other embodiments, the L-shaped component 122 can be replaced with other styles, such as a V-shaped component, a rectangular block, a circular component, etc.; and the electronic mirror 121 and the positioning sleeve 11 can be directly pivotally connected by a pivot shaft, thus omitting the slide 120 and the L-shaped component 122, etc.
[0067] The control component 13 is used to adjust the position and viewing angle of the electronic mirror 12, so that the doctor can obtain the best surgical view and make the surgery more precise.
[0068] The control component 13 is used to control the sliding of the slide 120 back and forth and the left and right swing of the electronic endoscope 121. When the control component 13 controls the sliding of the slide 120 back and forth, it can adjust the distance between the front end of the electronic endoscope 121 and the lesion, so that it can be closely observed at the lesion or far away from the lesion to observe the surrounding situation. When the control component 13 controls the left and right swing of the electronic endoscope 121, it can adjust the left and right viewing angles at the same position, so that the lesion can be observed directly in front of and diagonally in front of or to the sides of the front end of the surgical instrument 20. The doctor can adjust the field of vision in a timely manner according to the actual needs, so as to facilitate the smooth operation of the surgery.
[0069] The structure of the control component 13 is not limited; it can be manually controlled or electrically controlled. Generally speaking, manual control can minimize the number of parts. In this embodiment, the control component 13 includes a pusher 130 and a rocker 131, which extend in the front-back direction.
[0070] The lengths of the pusher 130 and the rocker 131 can be set as needed. Generally, the lengths of the pusher 130 and the rocker 131 will be less than the length of the positioning sleeve 11, but the difference will not be too large. It is necessary to ensure that the rear ends of the pusher 130 and the rocker 131 are adjacent to the rear end of the positioning sleeve 11 to facilitate operation and control by medical personnel. Of course, in other embodiments, the lengths of the pusher 130 and the rocker 131 can be greater than the length of the positioning sleeve 11, or one of the pusher 130 and the rocker 131 can be greater than the length of the positioning sleeve 11 and the other can be less than the length of the positioning sleeve 11.
[0071] The front end of the pusher 130 is connected to the slide 120. The two can be directly or indirectly connected, and the connection method is not limited, such as integral molding, bonding, welding, or connection by threaded fasteners. When the doctor controls the pusher 130 to move back and forth, it can push the slide 120 to slide back and forth.
[0072] The front pusher 130 can be tubular, rod-shaped, or semi-tubular. In this embodiment, the front pusher 130 is semi-tubular with a C-shaped cross-section. The interior of the front pusher 130 is hollow, and the open side of the front pusher 130 mates with the positioning sleeve 11 to form a wiring conduit. Please refer to... Figure 6 As shown, the wire 123 can pass through the conduit and connect to the electron mirror 121 to realize functions such as power supply and signal transmission.
[0073] The front end of the rocker arm 131 is hinged to the electron mirror 121; the two can be directly or indirectly connected. In this embodiment, the electron mirror 121 and the rocker arm 131 are indirectly hinged via an L-shaped member 122, with the rocker arm 131 hinged to the second end or middle of the L-shaped member 122. The hinge axis between the L-shaped member 122 and the slide block 120 is the first hinge axis, and the hinge axis between the L-shaped member 122 and the rocker arm 131 is the second hinge axis. The first and second hinge axes are parallel or substantially parallel. Of course, in other embodiments, the first and second hinge axes can also be set at an angle, and the angle can be selected according to actual needs, such as 5°, 10°, etc. When the rocker arm 131 moves back and forth, it can drive the electron mirror 121 to rotate around the first hinge axis, thereby enabling the electron mirror 121 to rock left and right.
[0074] The control methods for the pusher 130 and the rocker 131 are not limited. For example, the pusher 130 has a pusher seat at its rear end, and the pusher seat and the positioning sleeve 11 have a first slider and a first groove respectively. The first slider and the first groove slide together, allowing medical staff to push the pusher seat to move, thereby controlling the pusher 130 to move forward or backward. The rocker 131 has a rocker seat at its rear end, and the rocker seat and the limiting seat have a second slider and a second groove respectively. The second slider and the second groove slide together, allowing medical staff to push the rocker seat to move while keeping the pusher seat stationary, thereby controlling the rocker 131 to move forward or backward. When the electronic endoscope 12 needs to slide back and forth, the medical staff only needs to push the limiting seat to slide back and forth. When the electronic endoscope 121 needs to rock left and right, the limiting seat only needs to be kept stationary, and then the rocker seat can be pushed to slide back and forth. Of course, in other embodiments, the first slider and the first slide groove can be replaced by a guide rod and a guide block, or the engagement method of the first slider and the second slide groove can be replaced by the rear end of the rocker member 131 engaging with the limiting seat via a rocker arm. In other embodiments, the rear ends of the pusher member 130 and the rocker member 131 may not be connected to the positioning sleeve 11, but can be directly maintained and controlled by the doctor manually.
[0075] In this embodiment, the control methods for the forward pusher 130 and the rocker 131 can adopt, but are not limited to, the following schemes: Please refer to... Figure 4 , Figure 5 As shown, the control component 13 also includes a first component 140 and a second component 150. The first component 140 and the second component 150 are located at the rear end of the positioning sleeve 11. The first component 140 and the second component 150 are used to control the forward and backward movement of the pusher 130 and the rocker 131, thereby realizing the forward and backward movement of the electron mirror 12 and the left and right swing of the electron mirror 121. Specifically, the first component 140 is connected to the pusher 130 and is used to push the rocker 131 forward and backward, while the second component 150 is connected to the positioning sleeve 11 and is used to push the first component 140 and the electron mirror 12 forward and backward. Alternatively, the rocker seat can be considered as the first component 140, and the pusher seat as the second component 150.
[0076] The first component 140 can be located in front of or behind the second component 150. The structures of the first component 140 and the second component 150 are not limited, and the following schemes can be adopted, but are not limited to: Please refer to... Figure 7As shown, the first component 140 can be located in front of the second component 150. Both the first component 140 and the second component 150 include a positioning cylinder, a push sleeve, and a rotating cylinder. For ease 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; the second component 150 includes a second positioning cylinder 151, a second push sleeve 152, and a second rotating cylinder 153. 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.
[0077] Please combine Figure 12 , Figure 13 As shown, the positioning cylinder has a cylindrical or tubular structure, such as round tubes, square tubes, irregularly shaped tubes, etc., and is hollow inside. The first positioning cylinder 141 is connected to the front pusher 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 between the first positioning cylinder 141 and the front pusher 130, and between the second positioning cylinder 151 and the positioning sleeve 11, is not limited and can be sleeved, glued, etc.
[0078] Please combine Figure 14 As shown, the shape of the push sleeve is not limited; it can be cylindrical or tubular, such as a round tube, square tube, or irregularly shaped tube. The shape of the push sleeve can match the positioning cylinder. In this embodiment, the first push sleeve 142 is sleeved on the first positioning cylinder 141. The first push sleeve 142 can slide back and forth along the first positioning cylinder 141, but the first push sleeve 142 cannot rotate around the center line of the first positioning cylinder 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 cylinder 141 are both square tubes, then the two cannot rotate relative to each other. If the first push sleeve 142 and the first positioning cylinder 141 are both round tubes, then a circumferential limiting structure needs to be added to circumferentially limit the first push sleeve 142, ensuring that the first push sleeve 142 can only slide back and forth along the first positioning cylinder 141 and cannot rotate around the first positioning cylinder 141. The second push sleeve 152 is fitted onto the second positioning cylinder 151. The second push sleeve 152 can slide back and forth along the second positioning cylinder 151, but the second push sleeve 152 cannot rotate around the center line of the second positioning cylinder 151. The structure of the two can be referred to the connection relationship between the first push sleeve 142 and the first positioning cylinder 141. Furthermore, the front end of the second push sleeve 152 is connected and fixed to the first positioning cylinder 141.
[0079] The circumferential limiting structure between the push sleeve and the positioning cylinder is not limited. In this embodiment, the first positioning cylinder 141 is provided with a first axial groove 144, and the first push sleeve 142 is provided with a first movable member 145. The first movable member 145 is embedded in the first axial groove 144 and can limit the circumferential movement of the first push sleeve 142. The second positioning cylinder 151 is provided with a second axial groove 154, and the second push sleeve 152 is provided with a second movable member 155. The second movable member 155 is embedded in the second axial groove 154 and can limit the circumferential movement of the second push sleeve 152.
[0080] The movable part can be block-shaped, spherical, etc., and the movable part and the push sleeve can be integrally formed, bonded, or detachably connected. In this embodiment, the following scheme can also be adopted: the first push sleeve 142 is provided with a first mounting through hole, the first movable part 145 is a first ball, part of the first ball is located in the first mounting through hole and the other part is embedded in the first axial groove 144. The outer side of the first mounting through hole can be limited by the first rotating cylinder 143, or it can be limited by other means, such as by sealing the outer side of the first mounting through hole with a first sealing member; the second push sleeve 152 is provided with a second mounting through hole, the second movable part 155 is a second ball, part of the second ball is located in the second mounting through hole and the other part is embedded in the second axial groove 154. The outer side of the second mounting through hole can be limited by the second rotating cylinder 153, or it can be limited by other means, such as by sealing the outer side of the second mounting through hole with a second sealing member.
[0081] The rotating cylinder is rotatably fitted onto the positioning cylinder. The rotating cylinder can only rotate around the center line of the positioning cylinder, but cannot slide back and forth relative to the positioning cylinder. The connection method between the two is not limited. For example, in this embodiment, a circumferential first protruding ring 148 is provided on the outer side of the first positioning cylinder 141, and a circumferential first recessed groove is provided on the inner side of the first rotating cylinder 143. The first protruding ring 148 is embedded in the first recessed groove, and there is a sliding fit between the first protruding ring 148 and the first recessed groove. The arrangement of the first recessed groove is not limited. For example, the rear end of the first rotating cylinder 143 includes a first main body 146 and a first sealing ring 147. 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, medium holes, and small holes according to their diameter. The first sealing ring 147 is provided at the large hole of the stepped hole, and the side wall end of the first sealing ring 147 and the small hole limits the first protruding ring 148 to the medium hole of the stepped hole. The first sealing ring 147 can be removed from the first rotating cylinder 143, thereby allowing the first protruding ring 148 to detach from the first rotating cylinder 143, facilitating the installation and removal of the first rotating cylinder 143 and the first positioning cylinder 141.
[0082] Similarly, the outer side of the second positioning cylinder 151 is provided with a circumferential second protruding ring 158, and the inner side of the second rotating cylinder 153 is provided with a circumferential second recessed groove. The second protruding ring 158 is embedded in the second recessed groove, and the second protruding ring 158 and the second recessed groove are slidably engaged. The rear end of the second rotating cylinder 153 includes a second main body 156 and a second sealing ring 157.
[0083] In other embodiments, other alternatives may be used, for example, the raised ring may be replaced by multiple raised portions that are distributed circumferentially around the positioning cylinder.
[0084] The rotating drum and the push sleeve are threadedly engaged. Specifically, in this embodiment, part or all of the first push sleeve 142 is located inside the first rotating drum 143. The inner surface of the first rotating drum 143 is provided with an internal thread, and the outer surface of the first push sleeve 142 is provided with an external thread. The internal thread and the external thread engage. When the first rotating drum 143 rotates, the first push sleeve 142 can be pushed to slide back and forth under the cooperation of the internal and external threads. Part or all of the second push sleeve 152 is located inside the second rotating drum 153. The inner surface of the second rotating drum 153 is provided with an internal thread, and the outer surface of the second push sleeve 152 is provided with an external thread. The internal thread and the external thread engage. When the second rotating drum 153 rotates, the second push sleeve 152 can be pushed to slide back and forth under the cooperation of the internal and external threads.
[0085] The first push sleeve 142 is connected to the rocker component 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 back and forth, thereby pushing the rocker component 131 to move back and forth; when the second rotating cylinder 153 is rotated, the second push sleeve 152 can slide back and forth, thereby pushing the first assembly 140 to move back and forth as a whole, that is, the front pusher component 130, the rocker component 131 and the electron mirror 12 move back and forth simultaneously.
[0086] The second component 150 is provided with a locking bolt 159. 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 passes through the through hole and the two are threadedly engaged. The locking bolt 159 is used to press and fix the surgical instrument 20. Of course, in other embodiments, the second component 150 and the surgical instrument 20 can also adopt other fixing methods, such as adhesive bonding, snap-fit bonding, etc.
[0087] Surgical instrument 20 utilizes existing technology, and the type of surgical instrument 20 is not limited. For example, surgical instrument 20 may use, but is not limited to, radiofrequency ablation electrodes (see reference). Figure 1 (As shown), planer (please refer to) Figure 2 (As shown), a knife sharpening device.
[0088] The surgical instrument 20 is connected and fixed to the camera mechanism 10. The connection method between the surgical instrument 20 and the camera mechanism 10 is not limited and needs to be installed according to the specific structure of the camera mechanism 10. In this embodiment, the rod-shaped portion of the surgical instrument 20 is inserted into the tubular portion 110 of the positioning sleeve 11 and extends to the C-shaped portion 112. Furthermore, the front end of the surgical instrument 20, such as an electrode head, a planer head, or a grinding head, is embedded and fixed within the C-shaped portion 112. Generally, the front end of the surgical instrument 20 is further forward than the camera mechanism 10. After the surgical instrument 20 is inserted into place, the surgical instrument 20 and the camera mechanism 10 can be locked together using the locking bolt 159.
[0089] In other embodiments, if the positioning sleeve 11 is a cylindrical 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.
[0090] Surgical instruments 20 are used to perform pre-set surgical procedures, such as radiofrequency ablation electrodes to ablate and stop bleeding at the lesion site, shaving instruments to shave at the lesion site, and grinding instruments to grind at the lesion site such as bone. During this process, the camera mechanism 10 can automatically adjust the surgical angle as needed, so that medical staff can clearly observe the operation at the front end of the surgical instruments 20 and make adjustments.
[0091] The method of using the medical power device 100 provided in this embodiment is as follows:
[0092] Please combine Figure 1 , Figure 2 As shown, the surgical instrument 20 is inserted into the camera mechanism 10 and the two are locked together by the locking screw 159;
[0093] The surgical instrument 20 and the camera device 10 are inserted into the human body through a pre-drilled hole, with their tips close to the lesion site.
[0094] Please combine Figure 15 As shown, when it is necessary to move the electronic endoscope 12 closer to or further away from the lesion, that is, when it is necessary to move the electronic endoscope 12 back and forth, the doctor grasps the positioning sleeve 11 or the second positioning cylinder 151 to keep the positioning sleeve 11 stationary; rotate the second rotating cylinder 153, the second rotating cylinder 153 drives the second push sleeve 152 to slide back and forth, 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 back and forth, that is, the first component 140 moves back and forth as a whole, and the first component 140 pushes the electronic endoscope 12 back and forth through the front pusher 130.
[0095] Please combine Figures 16-19As shown, when it is necessary to change the viewing angle, that is, to make the electron mirror 121 swing left and right, grasp the positioning sleeve 11 or the second positioning cylinder 151 to keep the positioning sleeve 11 and the second component 150 stationary; rotate the first rotating cylinder 143, which drives the first push sleeve 142 to slide back and forth. At this time, since the front push member 130 is connected to the first positioning cylinder 141 and remains stationary, the first push sleeve 142 drives the swing member 131 to move back and forth, thereby making the electron mirror 121 rotate around the first hinge axis and realize the left and right swing of the electron mirror 121.
[0096] Start the surgical instrument 20 to begin working and perform radiofrequency ablation, shaving, or grinding on the lesion site.
[0097] The above steps can be added, removed, modified, or their order adjusted as needed. For example, if there is no first component 140 and second component 150, but a structure such as a front pusher and a rocker is used, the front pusher and rocker can be manually pushed to slide back and forth to achieve the overall back and forth movement of the front pusher 130 and the rocker 131; the rocker can be manually pushed to slide back and forth to achieve the front pusher 130 remaining stationary while the rocker 131 moves back and forth.
