Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically, to a surgical tool with navigation function. Background Technology

[0002] Nasal bone reshaping surgery, an important branch of cosmetic and reconstructive surgery, aims to improve the appearance of the nose or repair nasal deformities caused by trauma, congenital defects, or other reasons by surgically adjusting the nasal bone structure. Nasal bone surgery can both correct the shape of the nose to enhance personal image and effectively improve nasal breathing function. Traditional nasal bone reshaping surgery mainly includes procedures such as nasal bone osteotomy, nasal bone narrowing, nasal bone elevation, and nasal tip reshaping, involving precise adjustments to the nasal bone, nasal septum cartilage, and other related structures.

[0003] In related technologies, most instruments used in nasal bone reshaping surgery are made of metal or hard plastic, including but not limited to osteotomy blades, bone chisels, repositioning forceps, and retractors. These instruments are usually designed to be handheld and operated directly by the doctor, who relies on touch and visual assessment to perform the surgery. The control of force during the operation mainly depends on the doctor's experience and skill. However, due to the lack of real-time force monitoring and quantitative guidance, it is difficult for doctors to accurately grasp the force applied during the operation, which may increase the uncertainty of the correction effect and easily lead to overcorrection or undercorrection. Summary of the Invention

[0004] The technical problem to be solved by this invention is to address the defects and deficiencies of the prior art by proposing a surgical tool with navigation function. The force fed back from the end of the dissector can be displayed on the reading instrument through a force sensor, allowing doctors to intuitively and accurately obtain the magnitude of the operating force without relying on experience for estimation, thus avoiding the problem of overcorrection or undercorrection due to force estimation errors.

[0022] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0023] like Figures 1-4 As shown, the surgical tool with navigation function according to an embodiment of the present invention includes a body, a dissector 3, and a navigation component.

[0024] Specifically, the peeler 3 is connected to one end of the body, which is used for the operator to hold, and the peeler 3 is used to insert into the surgical position. The navigation component includes a force sensor 5 and a reading instrument. The force sensor 5 is located on the body and connected to the reading instrument. The peeler 3 is connected to the body through the force sensor 5.

[0025] Understandably, since the dissector 3 is connected to the force sensor 5, when the surgical tool with navigation function of this application is used for surgery, the force fed back by the dissector 3 can be directly displayed on the reading instrument through the force sensor 5. The doctor can intuitively and accurately obtain the magnitude of the force, thereby solving the instability caused by relying on experience to grasp the force, and thus avoiding the problem of overcorrection or undercorrection due to force prediction errors, ensuring the safety and correction effect of the surgery.

[0026] The surgical tool with navigation function in this embodiment of the invention includes a navigation component comprising a force sensor 5 and a reading instrument. The force sensor 5 is disposed on the main body and connected to the reading instrument. The dissector 3 is connected to the main body through the force sensor 5. Thus, during the operation, the force fed back from the end of the dissector 3 can be displayed on the reading instrument through the force sensor 5. The doctor can intuitively and accurately obtain the magnitude of the operating force without relying on experience for estimation, avoiding the problem of overcorrection or undercorrection due to force estimation errors, and ensuring the safety and corrective effect of the operation.

[0027] In some embodiments, such as Figure 1 As shown, the main body includes a handle 1 and a finger support 2 connected to one end of the handle 1. The handle 1 is for the operator to hold, and the finger support 2 gradually tapers away from the handle 1. The outer circumferential surface of the finger support 2 is an inwardly concave arc surface, and the peeler 3 is inserted through the finger support 2. Specifically, in actual operation, the doctor's dominant hand is in a grasping posture to hold the main body. The thumb and index finger can grip the finger support 2 and operate the mechanism. The concave arc surface design of the finger support 2 meets the requirements of finger fit, making the grip more stable and the operation feedback more sensitive.

[0028] Furthermore, such as Figure 2 As shown, the body has a cavity, and the force sensor 5 is disposed inside the cavity. One end of the peeler 3 passes through the body and extends into the cavity. Thus, the body can act as a protective shell to protect the force sensor 5 inside, while optimizing the overall structure and appearance and improving operational dexterity.

[0029] Furthermore, the cavity includes a connected mounting cavity and a guide groove. The force sensor 5 is located inside the mounting cavity, and one end of the peeler 3 passes through the guide groove and extends into the mounting cavity. Thus, the guide groove can guide and position the peeler 3 during installation, improving the stability and reliability of the peeler 3 assembly.

[0030] Preferably, the mounting cavity is located inside the handle portion 1, and the guide groove extends through the finger support portion 2.

[0031] Preferably, the handle 1 and the finger support 2 are connected by screws, that is, the handle 1 and the finger support 2 are two detachable independent structural parts, which makes it easy to disassemble the body for maintenance when the internal components are damaged or need to be replaced.

[0032] In addition, considering that the length of the peeler 3 may vary under different application environments, a single-length body cannot flexibly adapt to various models of peelers 3. For example, when the peeler 3 is longer, theoretically the finger support 2 needs to be lengthened to improve the stability and coordination of the overall assembly. However, this application constructs the finger support 2 and the handle 1 as two detachable structural components, so that the handle 1 can be equipped with a corresponding model of finger support 2 according to the model of the peeler 3, without redesigning the entire body structure, which has high application flexibility and versatility.

[0033] Furthermore, such as Figure 2 As shown, the force sensor 5 includes a front-end sensor and a rear-end sensor. The front-end sensor is located at the end of the mounting cavity facing the finger support 2, and the rear-end sensor is located at the end of the mounting cavity away from the finger support 2. The peeler 3 is connected to both the front-end and rear-end sensors. Therefore, the front-end and rear-end sensors can verify each other, ensuring the accuracy of the acquired data.

[0034] Furthermore, a wire-passing hole 7 is provided on the end wall of the cavity away from the stripper 3, and a wire-clamping plate 6 extending toward the wire-passing hole 7 is provided on the bottom wall of the cavity. The wire-clamping plate 6 and the bottom wall of the cavity form a wire-passing groove. The wire-passing groove and the wire-passing hole 7 are used for the connection wire of the force sensor 5 to pass through.

[0035] Furthermore, the handle portion 1 includes a housing 11 and a cover 12. The housing 11 is connected to the finger support portion 2 and has a mounting cavity. The mounting cavity has an opening on at least one side in a first direction. The cover 12 is detachably connected to the opening. The first direction is perpendicular to the length direction of the peeler 3.

[0036] like Figure 2 As shown, the housing 11 includes a bottom shell and two side plates and a rear end plate connected to the bottom shell. The bottom shell, the two side plates and the rear end plate form an installation cavity. The bottom shell and the two side plates form a U-shaped shell. The front end face of the U-shaped shell is provided with four screw holes for connecting the finger support part 2. The upper end face of the U-shaped shell is provided with three screw holes for connecting the cover plate. The four screw holes at the front end are arranged in pairs on the two side plates and spaced apart in the vertical direction. Two of the three screw holes on the top surface are located on the two side plates respectively, and the other is located on the rear end plate.

[0037] Furthermore, such as Figure 2As shown, the force sensor 5 is equipped with a fixing member, which has a through groove for the peeler 3 to pass through. At least one side wall of the through groove has a threaded hole for mounting a fastening screw. During assembly, the housing 11 is in the open state. First, the fixing member is connected to the force sensor 5. Then, the peeler 3 is passed through the through groove and the fastening screw is tightened. At this time, the force sensor 5, the fixing member, and the peeler 3 form a whole. Then, this whole is installed into the handle part 1 and the force sensor 5 is connected to the handle part 1. After that, the finger support part 2 is connected to the handle 1. Finally, the cover 12 is connected to the housing 11 to complete the structural assembly.

[0038] Preferably, the fastener is connected to the end of the force sensor 5 facing the cover 12, and the groove wall facing the cover 12 has a threaded hole. Figure 3 As shown, the handle portion 1 has an opening at the top, and the bottom of the force sensor 5 is connected to the bottom wall of the handle portion 1. A fixing component is provided at the top, including a U-shaped force sensor fixing component 51 and a block-shaped peeler fixing component 31. The slot of the U-shaped force sensor 5 faces upward, and the peeler fixing component 31 is located in the U-shaped slot of the sensor fixing component and has a through groove. It can be understood that when the cover 12 is opened, both the force sensor fixing component 51 and the peeler fixing component 31 are exposed at the opening of the handle portion 1, which facilitates maintenance.

[0039] Preferably, the force sensor 5 is cylindrical, with connecting holes on its upper and lower ends for connecting the force sensor fixing member 51 and the handle portion 1, respectively. The force sensor fixing member 51 has connecting holes on its two side walls for connecting the peeler fixing member 31. In actual assembly, the force sensor fixing member 51 and the peeler fixing member 31 can be connected first, and then the entire fixing member can be brought into the assembly process.

[0040] Preferably, a calibration plate 4 is connected to at least one side of the body. Thus, after calibration by the calibration plate 4, the computer can calculate the spatial position of the end of the peeler 3, thereby improving the accuracy of the operation. It should be noted that the method of using the calibration plate 4 is a conventional technical means in the field and will not be described in detail here.

[0041] Preferably, the calibration plate 4 is connected to the side of the handle portion 1 by welding.
