Description

Technical Field

[0001] This application relates to the field of surgical instruments, and in particular to a tracking frame and trephine system. Background Technology

[0002] Percutaneous endoscopic discectomy (PED) has become one of the effective minimally invasive surgical treatments for lumbar disc herniation. The trephine saw is a commonly used surgical instrument in PED, effectively removing bony tissue. It offers advantages such as minimal trauma, small incision, no need for muscle dissection, minimal bone removal, minimal impact on spinal stability, rapid recovery, and short hospital stay. Currently, PED techniques are largely mature and have achieved good clinical results in spinal decompression surgery.

[0003] Current technologies often employ endoscopic trephine saws. However, the endoscopic operating channel restricts the trephine's operating direction, limiting the visible area. Insertion of the trephine requires individual positioning, and the saw teeth can easily damage surrounding nerves. During operation, one hand must hold the working cannula and endoscope, while the other hand applies forward pressure and rotates the trephine to grind bone. As the trephine moves, the endoscope cannot keep up, causing the saw teeth to leave the endoscopic view, necessitating additional adjustments to the positional relationship between the endoscope and the trephine. This not only makes operation extremely inconvenient for doctors but also poses a risk of accidental injury to patients. Therefore, some trephine saws incorporate a tracker, including a reflector, to indicate the trephine's position.

[0004] However, the insufficient brightness of the reflector resulted in poor positioning of the ring saw, affecting the doctor's operation. Utility Model Content

[0005] Based on this, a tracking frame and trephine system are provided to improve positioning and enhance the accuracy of doctors' operations.

[0006] Therefore, in a first aspect, embodiments of this application provide a tracking frame connected to a ring saw. The tracking frame includes: a frame body for connecting to the ring saw; LED beads disposed on the side of the frame body away from the ring saw; a power supply assembly disposed on the frame body and electrically connected to the LED beads; and a switch disposed on the frame body and electrically connected to the LED beads and / or the power supply assembly for controlling the opening and closing of the LED beads.

[0007] In one embodiment, the frame is provided with a mounting groove, the light-emitting LED is located in the mounting groove, and the inner diameter of the mounting groove gradually increases towards the open end.

[0008] In one embodiment, the power supply assembly includes a battery installed inside the frame, and the battery is electrically connected to the switch and the LED beads.

[0009] In one embodiment, the power supply assembly includes an external interface connected to the frame and electrically connected to the switch and the LED beads.

[0010] In one embodiment, the tracking frame further includes a locking assembly comprising a sleeve connected to the frame body, the sleeve having an inner cavity for housing the ring saw and the sleeve being detachably connected to the ring saw.

[0011] In one embodiment, the sleeve is provided with a locking groove, and one end of the locking groove is provided with a fixing hole, which is used to correspond to the annular groove of the ring saw.

The middle part of the locking member is rotatably connected to the sleeve through the rotating shaft. One end of the locking member is provided with a locking part for extending into the annular groove through the fixing hole. The other end of the locking member is connected to the sleeve through the elastic member.

[0012] In one embodiment, the sleeve is provided with a pressing groove at the location corresponding to the elastic element.

[0013] Secondly, embodiments of this application provide a ring saw system, including a ring saw and a tracking frame as described in any of the preceding claims.

[0014] In one embodiment, the ring saw is provided with a ring groove into which the locking portion of the tracking frame extends.

[0015] In one embodiment, a handle is also included, which is detachably connected to one end of the ring saw.

[0016] According to the tracking frame and ring saw system provided in this application embodiment, the tracking frame is connected to the ring saw. The tracking frame includes a frame body, LED beads, a power supply component, and a switch. The frame body is used to connect to the ring saw.

The switch is disposed on the frame body and electrically connected to the LED beads and / or the power supply component to control the switching of the LED beads. During operation, when needed, the switch is turned on, which electrically connects the power supply component to the LED beads, supplying power to the LED beads, causing them to emit light for the doctor's operation. When not needed, the switch is turned off, which disconnects the power supply component from the LED beads, causing them to stop emitting light and saving electricity. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0024] It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Therefore, the drawings only show the components related to this utility model and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0025] The structures, proportions, sizes, etc., illustrated in the accompanying drawings of this specification are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the implementation conditions of this utility model. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportional relationships, or adjustments to the size, without affecting the effects and purposes that this utility model can produce, should still fall within the scope of the technical content disclosed in this utility model.

[0026] The orientations or positional relationships indicated by terms such as "upper," "lower," "left," "right," "middle," "longitudinal," "transverse," "horizontal," "inner," "outer," "radial," and "circumferential" used in this specification are based on the orientations or positional relationships shown in the accompanying drawings and are only for the purpose of simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] Current technologies often employ endoscopic trephine saws. However, the endoscopic operating channel restricts the trephine's operating direction, limiting the area visible under the endoscope. Insertion of the trephine requires individual positioning, and the saw teeth can easily damage surrounding nerves. During operation, one hand must hold the working cannula and endoscope, while the other hand applies forward pressure and rotates the trephine to grind bone. As the trephine moves, the endoscope cannot keep up, causing the saw teeth to leave the endoscopic view, necessitating additional adjustments to the positional relationship between the endoscope and the trephine. This not only makes the doctor's operation extremely inconvenient but also poses a risk of accidental injury to the patient. Therefore, some trephine saws incorporate a tracker, including a reflector, to indicate the trephine's position. However, the reflector's brightness is insufficient, resulting in poor trephine positioning and affecting the doctor's operation.

[0028] To solve the above problems, refer to Figure 1 and Figure 2 , Figure 1 This diagram illustrates the structure of a ring saw system according to an embodiment of this application. Figure 2 This diagram illustrates the structure of a tracking frame provided in an embodiment of this application.

[0029] This application includes a tracking frame connected to a ring saw 1. The tracking frame includes a frame body 2, LED beads 3, a power supply component 4, and a switch 5. The frame body 2 is used to connect to the ring saw 1. The LED beads 3 are disposed on the side of the frame body 2 away from the ring saw 1. The power supply component 4 is disposed on the frame body 2 and is electrically connected to the LED beads 3. The switch 5 is disposed on the frame body 2 and is electrically connected to the LED beads 3 and / or the power supply component 4 to control the opening and closing of the LED beads 3.

[0030] It should be understood that the tracking frame is connected to the ring saw 1, and the connection method can be a fixed connection or a detachable connection; this application does not impose any restrictions. In one example, the tracking frame and the ring saw 1 are detachably connected, which facilitates the replacement of the ring saw 1 and allows the tracking frame to be reused.

[0031] The tracking frame includes a frame body 2, which is formed by injection molding. The frame body 2 is used to connect with the ring saw 1. The frame body 2 is provided with multiple supports to facilitate the installation of other components. The tracking frame also includes LED beads 3, which are located on the side of the frame body 2 away from the ring saw for easy identification by the doctor. The LED beads 3 are automatically emitting light, which can increase brightness, thereby improving the positioning of the ring saw 1 and improving the accuracy of the doctor's operation.

[0032] It also includes a power supply component 4 and a switch 5. The power supply component 4 is installed on the frame 2 and is electrically connected to the light-emitting lamp 3 to supply power to the light-emitting lamp 3. The switch 5 is installed on the frame 2 and is electrically connected to the power supply component 4 and / or the light-emitting lamp 3, that is, the switch 5 can be used to control the opening and closing of the light-emitting lamp 3.

[0033] When in use, switching on switch 5 connects the power supply component 4 to the LED bead 3, supplying power to the LED bead 3, which then emits light to facilitate the doctor's operation. When not in use, switching on switch 5 disconnects the power supply component 4 from the LED bead 3, stopping the LED bead 3 from emitting light and saving electricity.

[0034] Furthermore, for ease of identification, multiple light-emitting LED beads 3 can be set, such as two, three or four. This application does not impose any restrictions. In one example, four light-emitting LED beads 3 are set and spaced apart. The frame 2 is provided with four supports, and the four light-emitting LED beads 3 are respectively installed at the ends of the four supports.

[0035] This application also includes a control center, whose circuit board is a flexible circuit board that can be used once or repeatedly, enabling the application to perform low-temperature sterilization multiple times.

[0036] In some optional embodiments, the frame 2 is provided with a mounting groove 21, in which the LED beads 3 are located. The inner diameter of the mounting groove 21 gradually increases towards the open end. The LED beads 3 being located in the mounting groove 21 improves the stability of their installation, and the height of the LED beads 3 can be lower than the opening of the mounting groove 21, thus protecting them. Furthermore, the gradual increase in the inner diameter of the mounting groove 21 towards the open end reduces obstruction of the light from the LED beads 3, increases their brightness, and facilitates operation.

[0037] Reference Figure 1 and Figure 2 In some optional embodiments, the power supply assembly 4 includes a battery 41, which is installed inside the frame 2 and electrically connected to the switch 5 and the LED beads 3. The battery 41 is located inside the frame 2 to avoid external influences, thereby improving its lifespan. Compared to connecting to an external power source via an external interface, the battery 41 is easier to move and improves operational convenience.

[0038] In some optional embodiments, the power supply assembly 4 includes an external interface 42, which is connected to the frame 2 and electrically connected to the switch 5 and the LED beads 3. The external interface 42 can be connected to an external power source, which, compared to the battery 41, results in a longer battery life and more stable voltage, thus making the LED beads 3 emit light more stably.

[0039] In some optional embodiments, the power supply assembly 4 may include both a battery 41 and an external interface 42. When the battery 41 is depleted, power can be supplied to the LED beads 3 through the external interface 42, which can reduce the occurrence of accidents and improve the effectiveness of this application.

[0040] Reference Figures 1-3 , Figure 3 This diagram illustrates the structure of a locking assembly according to an embodiment of this application. In some optional embodiments, the tracking frame further includes a locking assembly 6, which includes a sleeve 61 connected to the frame body 2. The inner cavity of the sleeve 61 is used to accommodate a ring saw 1, and the sleeve 61 and the ring saw 1 are detachably connected. The connection between the sleeve 61 and the frame body 2 can be either a fixed connection or a detachable connection. In one example, the sleeve 61 is fixedly connected to the frame body 2. The sleeve 61 accommodates the ring saw 1, and the connection between the sleeve 61 and the ring saw 1 is detachable. After the ring saw 1 is used, it can be removed from the sleeve 61 and disposed of as a waste medical device. The tracking frame can then be reused, making the tracking frame reusable and saving costs.

[0041] In some optional embodiments, the sleeve 61 is provided with a locking groove 611, and one end of the locking groove 611 is provided with a fixing hole 612. The fixing hole 612 is used to correspond to the annular groove 11 of the ring saw 1. The locking assembly 6 also includes a locking member 62, an elastic member 63 and a rotating shaft 64 located in the locking groove 611. The middle part of the locking member 62 is rotatably connected to the sleeve 61 through the rotating shaft 64. One end of the locking member 62 is provided with a locking part 621 for extending into the annular groove 11 through the fixing hole 612. The other end of the locking member 62 is connected to the sleeve 61 through the elastic member 63.

[0042] A locking groove 611 is provided on the outer peripheral wall of the sleeve 61, extending along the length of the sleeve 61. A fixing hole 612 is located at one end of the locking groove 611 along its length, penetrating the sleeve 61 and corresponding to the annular groove 11 of the ring saw 1. A rotating shaft 64 is located in the locking groove 611 and at its center, perpendicular to the locking groove 611. A locking member 62 is located in the locking groove 611, with its center rotatably connected to the rotating shaft 64. A locking portion 621 protrudes from one end of the locking member 62 corresponding to the fixing hole 612. The locking portion 621 extends into the annular groove 11 of the ring saw 1 through the fixing hole 612, thus connecting with the ring saw 1 without affecting its rotation. To facilitate the insertion of the locking portion 621 into the annular groove 11, the width of the locking portion 621 gradually decreases towards the annular groove 11. The elastic element 63 is located at the end of the locking groove 611 away from the fixing hole 612, and the end of the locking part 621 away from the locking part 621 is connected to the sleeve 61 through the elastic element 63. The elastic element 63 can be a disc spring, spring or other elastic element, and this application does not limit it.

[0043] In use, press one end of the locking part 621 corresponding to the elastic member 63 to compress the elastic member 63, reducing the depth of the locking part 621 into the fixing hole 612, so that the sleeve 61 can be easily fitted onto the periphery of the ring saw 1. When the fixing hole 612 corresponds to the ring groove 11 of the ring saw 1, do not press the locking part 621, the elastic member 63 returns to its original position, and the locking part 621 extends from the fixing hole 612 into the ring groove 11, thereby connecting the sleeve 61 to the ring saw 1.

[0044] The locking groove 611 has two sections, symmetrically arranged along the central axis of the sleeve 61. The locking element 62, elastic element 63, and rotating shaft 64 are also provided in two sections. The arrangement of the two locking grooves 611, locking element 62, elastic element 63, and rotating shaft 64 further improves the stability of the connection between the tracking frame and the ring saw 1.

[0045] In some optional embodiments, the sleeve 61 is provided with a pressing groove 613 at the corresponding elastic element 63. The pressing groove 613 facilitates pressing by the operator and improves the ease of installation of this application.

[0046] This application also includes a ring saw system, comprising a ring saw 1 and a tracking frame as described in any of the preceding claims. The tracking frame is connected to the ring saw 1 and includes a frame body 2, LED beads 3, a power supply assembly 4, and a switch 5. The frame body 2 is used to connect to the ring saw 1; the LED beads 3 are disposed on the side of the frame body 2 away from the ring saw 1; the power supply assembly 4 is disposed on the frame body 2 and is electrically connected to the LED beads 3; the switch 5 is disposed on the frame body 2 and is electrically connected to the LED beads 3 and / or the power supply assembly 4 for controlling the LED beads 3.

[0047] When in use, switching on switch 5 connects the power supply component 4 to the LED bead 3, supplying power to the LED bead 3, which then emits light to facilitate the doctor's operation. When not in use, switching on switch 5 disconnects the power supply component 4 from the LED bead 3, stopping the LED bead 3 from emitting light and saving electricity.

[0048] In some alternative embodiments, the ring saw 1 is provided with an annular groove 11 into which the locking portion 621 of the tracking frame extends. The annular groove 11 corresponds to the fixing hole 612 of the sleeve 61 so that the locking portion 621 of the locking member 62 can extend into it, thereby connecting the ring saw 1 to the tracking frame.

[0049] Reference Figure 1 and Figure 4 , Figure 4 This diagram illustrates a ring saw and a handle according to an embodiment of this application. In some optional embodiments, this application further includes a handle 7, which is detachably connected to one end of the ring saw 1. The handle 7 is inserted into the ring saw 1, and the circumferential side of the ring saw 1 used for connecting with the handle 7 is provided with at least a limiting plane to prevent relative rotation between the ring saw 1 and the handle 7.

[0050] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0051] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
