Description

Technical Field

[0001] The present application relates to the field of medical devices, and in particular to a surgical tool that uses electrical energy to perform surgery. Background Art

[0002] An electric hook is a surgical tool that uses the thermal, Faraday, and electrolytic effects of electric current to perform surgery. It typically uses a high-frequency hook. When in contact with the patient's body, it acts on the target tissue, separating and coagulating it, thereby achieving surgical goals such as cutting and hemostasis.

[0003] A surgical tool, including a surgical execution unit such as an electric hook, can be mounted on the end of a surgical robot's robotic arm. The robotic arm's movements move the surgical tool to position it within the target tissue. Furthermore, the electric hook is directly connected to a power supply cable, which supplies power to the hook, energizing it. This allows the hook to perform surgery on the target tissue.

[0004] During surgery, the electric hook rotates relative to the main body of the surgical tool, bending the power cable connected to the hook. Excessive bending during surgery can damage or destroy the power cable, shortening its service life. Furthermore, the rotation of the electric hook can cause the power cable to shift radially and axially, making its position unstable within the surgical tool, leading to cable deviation or even entanglement. This deviation or entanglement can hinder the rotation of the electric hook, affecting the operation of the surgical tool during surgery.

[0005] Therefore, in the field of surgical tools, there is a need for improving surgical tools including electric hooks to overcome the above-mentioned technical problems existing in surgical tools in the prior art. Summary of the Invention

[0006] This application is made to solve the technical problems existing in the above-mentioned prior art. The purpose of this application is to provide a surgical tool with an improved structure, in particular a surgical tool with an electric hook, which can allow the surgical execution part, such as the electric hook, of the surgical tool to rotate smoothly relative to the surgical tool body without negatively affecting the power supply cable that supplies power to the surgical execution part, such as reducing or even eliminating the risk of damage, breakage, entanglement, or displacement of the power supply cable.

[0007] The present application provides a surgical tool, which includes: a head assembly, on which a surgical execution part is provided; and a socket assembly, wherein the head assembly is movably connected to the socket assembly, and a power supply cable is provided in the socket assembly, and the power supply cable is configured to supply power to the surgical execution part. The surgical tool also includes a cable connection retaining mechanism, which is configured to maintain electrical connection between the power supply cable and the surgical execution part when the head assembly moves relative to the socket assembly.

[0008] In the surgical tool structured as described above, a cable connection and retention mechanism is provided to ensure electrical connection between the power cable and the surgical actuator when the head assembly moves relative to the base assembly, reducing or eliminating the risk of the power cable breaking, entanglement, or displacement. The cable connection and retention mechanism achieves these effects by, for example, supporting and guiding a curved power cable and keeping it stationary.

[0009] In one embodiment, the surgical implement is configured to be movable relative to the power supply cable, and the cable connection maintaining mechanism is configured to maintain electrical connection between the surgical implement and the power supply cable when the surgical implement moves relative to the power supply cable.

[0010] By arranging the surgical execution part to be movable relative to the power supply cable assembly, the power supply cable assembly can be kept stationary during the operation of the surgical tool, thereby reducing the risk of damage to the power supply cable assembly.

[0011] Specifically, the above-mentioned movement of the surgical execution part relative to the power supply cable is a rotational movement.

[0012] In another exemplary structure, a receiving cavity is formed between the head assembly and the seat assembly, and the power supply cable extends from the seat assembly through the receiving cavity and is connected to the surgical execution part; wherein the cable connection retention mechanism includes an anti-bending structure arranged in the receiving cavity, and the anti-bending structure is configured to support and guide the power supply cable when the power supply cable bends as the head assembly rotates relative to the seat assembly.

[0013] The accommodating cavity provides a space allowing the power supply cable to bend, and the anti-bending structure therein guides and supports the bent power supply cable, thereby preventing the power supply cable from being damaged due to excessive bending.

[0014] Preferably, the power supply cable and the surgical execution part are formed as one body, for example, they can be fixedly connected together by means of crimping or the like. In addition, the power supply cable and the surgical execution part are enclosed in the head assembly by injection molding, thereby forming an integrated head assembly. In such a structure, the power supply cable and the surgical execution part fixedly connected as one body can effectively ensure the effectiveness of the electrical connection between the power supply cable and the surgical execution part, and reduce the risk of the power supply cable being detached from the surgical execution part when the surgical execution part rotates relative to the head assembly. In addition, the integrated head assembly does not have gaps generated during conventional assembly, which helps to reduce the risk of bacterial growth and improves the reliability of disinfection and sterilization of the head assembly after one use.

[0015] Specifically, the surgical execution portion is an electric hook, the head assembly further includes an electric hook frame, the electric hook is fixed to the electric hook frame, and the electric hook frame is rotatably connected to the support assembly. The electric hook includes an electric hook body. The cable connection and retention mechanism includes a power connection portion formed on the electric hook body, at least a portion of which is an arc-shaped portion. When the electric hook rotates with the electric hook frame relative to the support assembly, the end of the power supply cable proximal to the electric hook always maintains electrical contact with the arc-shaped portion of the power connection portion.

[0016] Optionally, the cable connection retaining mechanism also includes a pin device formed in the seat assembly, the pin device includes an elastic pin, one end of the power supply cable close to the electric hook is crimped in the pin device and electrically connected to the elastic pin, and the elastic pin contacts the outer surface of the arc-shaped portion of the power connection part, so that the power supply cable always maintains electrical connection with the arc-shaped portion of the power connection part.

[0017] During the contact between the ejector pin device and the outer surface of the arc-shaped portion, the elastic biasing force of the elastic ejector pin ensures that it is always in contact with the arc-shaped portion and applies a certain contact pressure, thereby always maintaining the electrical connection between the power supply cable and the electric hook during the relative movement of the electric hook.

[0018] Further optionally, a narrow groove extending along the curved portion is formed on the outer surface of the curved portion of the power connection portion, and the elastic ejector pin is fitted in the narrow groove.

[0019] The provision of the narrow slot can prevent the elastic ejector pin from losing contact with the arc-shaped portion of the power connection portion due to lateral deviation, thereby ensuring that the power supply cable and the power hook always maintain electrical connection.

[0020] In a specific structure, the power connection portion is annular in shape, which allows the power hook head to maintain electrical connection from the power supply cable to the power hook when the power hook head rotates relative to the socket assembly.

[0021] In another exemplary structure, the cable connection retention mechanism includes: a first conductive member, the first conductive member is arranged on the head assembly, and the electric hook is fixedly connected to the first conductive member; and a second conductive member, the second conductive member is arranged on the support assembly, and one end of the power supply cable close to the electric hook is fixedly connected to the second conductive member, the first conductive member can move relative to the second conductive member, and the first conductive member always maintains electrical connection with the second conductive member.

[0022] More specifically, the first and second conductive members are cylindrical and coaxially arranged to be rotatable relative to each other. This cylindrical shape allows the first and second conductive members to be nested within each other, facilitating relative rotation therebetween while maintaining a large contact area between the first and second conductive members.

[0023] Optionally, the cable connection retention mechanism also includes a conductive joint, which is arranged between the first conductive member and the second conductive member, and the conductive joint includes: a sleeve portion, the sleeve portion contacts one of the first conductive member and the second conductive member; and at least one elastic sheet extending from the sleeve portion and contacting the other of the first conductive member and the second conductive member.

[0024] By providing the conductive joint, the stability of the electrical connection between the first conductive member and the second conductive member can be improved, and even if there is a gap between the first conductive member and the second conductive member, the electrical connection between them will not be affected.

[0025] Optionally, the electric hook and the electric hook frame are formed in one piece. The integrated electric hook and electric component have higher structural stability, eliminate the gaps caused by conventional assembly methods, and reduce the need for disinfection and sterilization.

[0026] In another exemplary structure, the electric hook rack includes a first clamping member and a second clamping member, which can be spliced together to fix the electric hook. The structure of the spliced first clamping member and the second clamping member allows for easy removal and replacement of the electric hook thereon.

[0027] Optionally, the head assembly further comprises a snap-fitting member that engages with outer surfaces of the first and second clamping members when the first and second clamping members are joined together to hold the first and second clamping members together. The snap-fitting member helps to improve the mating stability between the first and second clamping members.

[0028] More specifically, a first snap-fit groove is formed on the outer surface of the first clamping member, and a second snap-fit groove is formed on the outer surface of the second clamping member. When the first clamping member and the second clamping member are spliced together, the first snap-fit groove and the second snap-fit groove are connected, and the snap-fit members are fitted in the first snap-fit groove and the second snap-fit groove.

[0029] In another aspect of the present application, a surgical tool is provided, comprising: a head assembly having a surgical implement disposed thereon; and a socket assembly, the head assembly being movably connected to the socket assembly, and a power supply cable disposed in the socket assembly, the power supply cable being configured to supply power to the surgical implement. The power supply cable is integrally connected to the surgical implement, and the head assembly is formed by injection molding, with the power supply cable and the surgical implement encased in the head assembly, thereby forming a monolithic head assembly.

[0030] It also relates to a method for manufacturing the above-mentioned surgical tool, which includes the following steps: providing a surgical execution part and a power supply cable; fixing the surgical execution part and the power supply cable together to form an integral body; placing the integrated surgical execution part and power supply cable into a mold; injecting insulating material into the mold to injection-mold a head assembly, and covering the surgical execution part and the power supply cable in the head assembly.

[0069] To facilitate understanding of the present invention, specific embodiments of the surgical tool of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the drawings illustrate only preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Those skilled in the art may make various obvious modifications, variations, and equivalent substitutions to the present invention based on the embodiments shown in the drawings, and, provided that no contradiction exists, the technical features of the different embodiments described below may be arbitrarily combined with each other, all of which fall within the scope of the present invention.

[0070] <First embodiment>

[0071] Figures 1 to 6 A surgical tool 100 according to a first embodiment of the present invention is shown. Figure 1 shows a perspective view of a surgical tool 100, Figure 2 An exploded perspective view is shown in which the components of the surgical tool 100 are disassembled.

[0072] The surgical tool 100 includes a head assembly, such as the electric hook head 110 shown in the figure, which may include a surgical execution part such as an electric hook 111 (described in detail below). The surgical tool 100 also includes a seat assembly 120, and the electric hook head 110 is movably connected to the seat assembly 120. For example, the electric hook head 110 can rotate relative to the seat assembly 120, or can also perform other forms of movement, such as translation. The seat assembly 120 can be installed on the robotic arm of a surgical robot, and the surgical tool 100 is moved to the surgical position by the movement of the robotic arm. The electric hook head 110 rotates relative to the seat assembly 120 so that the electric hook 111 thereon is accurately aligned with the target surgical tissue.

[0073] The surgical tool 100 further includes a power supply cable assembly 130 , which extends through the socket assembly 120 and is connected to the electric hook head 110 to supply power to the electric hook 111 in the electric hook head 110 to activate the electric hook 111 .

[0074] like Figure 2 As further shown, the electric hook head 110 and the socket assembly 120 are connected together by a connector 140. The connector 140 is, for example, a rivet, a latch, or the like that passes through holes formed in the electric hook head 110 and the socket assembly 120, thereby rotatably connecting the electric hook head 110 to the socket assembly 120.

[0075] Figure 3 The figure shows an exploded perspective view of the electric hook head 110 of the surgical tool 100. The electric hook head 110 includes an electric hook 111 and an electric hook frame 112. The electric hook 111 is fixed to the electric hook frame 112. In the electric hook head 110, specifically the electric hook frame 112, it is rotatably connected to the socket assembly 120 to achieve the connection between the electric hook head 110 and the socket assembly 120.

[0076] The electric hook 111 can be made of, for example, a conductive metal material, while the electric hook frame 112 can be made of, for example, an insulating material such as plastic or resin. Furthermore, the electric hook 111 and the electric hook frame 112 are preferably integrally formed. Specifically, during the manufacturing process, the electric hook 111 is placed in a mold, and then the electric hook frame 112 is formed by injection molding or other methods. The electric hook 111 is then fixed to the electric hook frame 112, thereby forming a single-piece component.

[0077] The integrated electric hook head 110 thus formed can have a higher structural stability. Moreover, compared with the prior art structure in which the electric hook 111 and the electric hook frame 112 are assembled together, the integrated electric hook head 110 does not require analysis in the conventional assembly process, thereby reducing the need for disinfection and sterilization.

[0078] Furthermore, the electric hook 111 also includes a power connection portion 113 connected to its body, and the power connection portion 113 is preferably in the shape of a ring. In addition to the ring shown in the figure, the shape of the power connection portion 113 can also be set to other shapes with at least a portion of the arc portion. For example, the power connection portion 113 can be semicircular, or an arc portion with other radian values.

[0079] When the electric hook head 110 is rotatably connected to the socket assembly 120, the connecting member 140 can pass through the hole in the center of the annular power connection portion 113, allowing the electric hook 111 to rotate relative to the socket assembly 120 along with the electric hook frame 112, specifically around the connecting member 140 connecting them together. Preferably, a narrow groove 114 is formed on the outer surface of the power connection portion 113, particularly on the outer surface of the arcuate portion, for mating with a spring-loaded ejector pin 131 to be described below.

[0080] Figure 4 A schematic exploded perspective view of the socket assembly 120 is shown, wherein a power cable assembly 130 is connected to the socket assembly 120. The power cable assembly 130 includes a spring pin 131 and a power cable 132. The spring pin 131 includes a spring (not shown) that biases the pin of the spring pin 131 toward the power connection portion 113.

[0081] The power supply cable 132 is fixedly connected to the spring pin 131 by crimping or other means. The spring pin 131 passes through the body of the seat assembly 120 and cooperates with the power connection portion 113, especially the narrow slot 114 of the power connection portion 113. When the spring pin 131 is engaged in the narrow slot 114, the power supply cable 132 can supply power to the electric hook 111 to excite the electric hook 111.

[0082] Alternatively, the spring pin 131 may be integrally formed with the seat assembly 120 by injection molding or the like.

[0083] Figure 5 and 6 The schematic diagram shows the state in which the power connection portion 113 of the power hook 111 is mated with the spring-loaded pin 131 of the power cable assembly 130, wherein the spring-loaded pin 131 is fitted into the slot 114 of the power connection portion 113. The biasing force of the spring in the spring-loaded pin 131 ensures that the spring-loaded pin 131 is stably fitted into the slot 114 of the power connection portion 113.

[0084] In the above structure, due to the cooperation between the spring pin 131 and the relatively rotatable power connection portion 113, when the electric hook 111 rotates relative to the electric hook frame 112, a sliding contact is formed between the spring pin 131 and the power connection portion 113, and this sliding contact can be maintained at all times, thereby maintaining electrical communication between the power supply cable 132 and the electric hook 111. In this way, the cooperation between the at least partially arcuate power connection portion 113 of the electric hook 111 and the spring pin 131 of the power supply cable assembly 130 forms a cable connection maintenance mechanism, thereby maintaining electrical communication between the power supply cable 132 and the electric hook 111 at all times without pulling the power supply cable 132 during the rotation of the electric hook head 110.

[0085] <Second embodiment>

[0086] Figures 7 to 15 The structure of a surgical tool 200 according to a second embodiment of the present invention is shown. Unless otherwise specified or conflicting, the specific structures described above for the first embodiment also apply to the second embodiment. Detailed descriptions of structures identical or similar to those of the first embodiment will not be repeated. The following will primarily describe structures in the second embodiment that differ from those of the first embodiment.

[0087] Similar to the first embodiment, the surgical tool 200 of the second embodiment also primarily comprises two components: an electrical hook head 210 and a socket assembly 220. The electrical hook head 210 and the socket assembly 220 are rotatably connected to each other via a connector 240, such as a rivet or connecting pin. A power supply cable 230 extends through the socket assembly 220 and maintains electrical communication with an electrical hook 211 of the electrical hook head 210 via a conductive structure described in greater detail below.

[0088] The electric hook head 210 includes an electric hook 211 and an electric hook frame 212, with the electric hook 211 fixedly connected to the electric hook frame 212. The electric hook head 210 can rotate relative to the socket assembly 220, causing the power cable 230 to move during rotation, thereby causing unstable electrical connection between the power cable 230 and the electric hook 211, or even disconnection. To ensure that electrical connection between the electric hook 211 and the power cable 230 is maintained at all times, in the second embodiment, a first conductive member 251 and a second conductive member 252 are disposed between the electric hook 211 and the power cable 230, which together constitute the cable connection retention mechanism of the surgical tool 200.

[0089] from Figure 7 As can be seen in the figure, the electric hook 210 is provided with a first conductive member 251 at a position adjacent to the connector 240. The first conductive member 251 is preferably in the form of a cylindrical sleeve that can be sleeved onto the connector 240, thereby rotating around the connector 240 along with the electric hook 210. The electric hook 211 is relatively fixedly connected to the first conductive member 251.

[0090] A second conductive member 252 is disposed adjacent to the connector 240 on the support assembly 220. The second conductive member 252 is configured to be movable relative to the first conductive member 251 to achieve electrical contact. Preferably, the second conductive member 252 is in the form of a cylindrical sleeve that fits over the outer surface of the first conductive member 251 (as shown in the figure), or it can be sleeved within the first conductive member 251. Alternatively, the second conductive member 252 can have other structures that enable slidable contact with the first conductive member 251. The power supply cable 230 extending through the support assembly 220 can be fixedly connected to the second conductive member 252.

[0091] like Figure 11 As schematically shown in the figure, the first conductive member 251 and the second conductive member 252 are positioned to contact each other at a virtual surface c centered on the axis of the connector 240 to jointly form a contact surface centered on the rotation axis of the connector 240 and generate an electrical connection at the contact surface.

[0092] When the electric hook 211 rotates, the first conductive member 251 rotates around the connector 240, and at least a portion of the first conductive member 251 is located at the contact surface, so that the first conductive member 251 and the second conductive member 252 always maintain electrical contact. As a result, the electric hook 211 and the power supply cable 230 can maintain electrical connection with each other even when they rotate relative to each other.

[0093] Here, the contact surface between the first conductive member 251 and the second conductive member 252 can be an arcuate surface, or can also be a complete circumferential surface as shown in the figure. The contact surface is configured to ensure that the electrical connection between the first conductive member 251 and the second conductive member 252 is always maintained within the rotation range of the electric hook 211.

[0094] As can be seen from the above description, the provision of the first conductive member 251 and the second conductive member 252 replaces the direct electrical connection between the power cable 230 and the electrical hook 211. Thus, the rotation of the electrical hook 211 does not pull on the power cable 230, thereby reducing or even eliminating the risk of the power cable 230 shifting during the rotation of the electrical hook 211. Furthermore, problems such as loosening of the power cable 230 and poor electrical contact in the circuit are also alleviated, thereby ensuring the stability of the surgical tool 200 during operation. More specifically, the power cable 230 is directly connected to the second conductive member 252, while the connection between the power cable assembly 130 and the second conductive member 252 remains stationary. This prevents disconnection of the connecting structure, such as a weld, between the power cable 230 and the second conductive member 252, thereby extending the overall service life of the surgical tool 200.

[0095] like Figure 9 As shown in FIG, a pair of first connecting arms 214 are provided at one end of the electric hook frame 212, and a cavity for receiving the first conductive member 251 and the second conductive member 252 is formed between the pair of first connecting arms 214. Similarly, a second connecting arm 221 is formed on one end of the seat assembly 220. The position of the second connecting arm 221 corresponds to the position of the first connecting arm 214, and the second connecting arm 221 is rotatably connected to the first connecting arm 214 through a connecting member 240.

[0096] The first connecting arm 214 is formed with a first axial hole 215, and the second connecting arm 221 is formed with a second axial hole 222. During installation, the connecting member 240 passes through the first axial hole 215 and the second axial hole 222, thereby connecting the first connecting arm 214 to the second connecting arm 221.

[0097] The second connecting arm 221 is further provided with an axial groove 223, which is located outside the second axial hole 222. A cover plate 224 can be inserted into the axial groove 223, so that the outer surface of the bearing assembly 220 is flush after installation. When disassembling the surgical tool 200, the cover plate 224 can be removed from the axial groove 223.

[0098] Combine Figure 10 As can be seen, a small facet 256 is formed on the outer surface of the second sleeve 254. Correspondingly, a flat surface that matches the small facet 256 can be formed in the shaft groove 223. When the second sleeve 254 is installed in the shaft groove 223, the small facet 256 mates with the matching flat surface in the shaft groove 223, thereby preventing the second sleeve 254 from rotating relative to the seat assembly 220. In other words, when the electric hook 211 drives the first sleeve 253 to rotate, the small facet 256 can prevent the second sleeve 254 from rotating therewith.

[0099] Further optionally, a driven component is further provided in the electric hook frame 212, such as a rotating wheel 260 formed on the electric hook frame 212, which rotates about the axis of the connecting member 240. A wheel groove 261 may be provided on the outer circumferential surface of the rotating wheel 260, and the rotating wheel 260 may be driven by a component such as a transmission belt (not shown) that fits in the wheel groove 261.

[0100] Further, if Figure 14 and 15 As shown in FIG, the first conductive member 251 has a first conductive surface 257, and the second conductive member 252 has a second conductive surface 258. The first conductive surface 257 and the second conductive surface 258 cooperate with each other and always keep in contact with each other to ensure electrical connection between them.

[0101] More specifically, the first conductive surface 257 and the second conductive surface 258 have corresponding curved surfaces. The curved surfaces of the first conductive surface 257 and the second conductive surface 258 always align with each other throughout the rotational range of the electrical hook 211. The provision of the curved surfaces helps increase the contact area between the first conductive member 251 and the second conductive member 252, thereby improving the stability of the electrical connection therebetween.

[0102] Of course, the first conductive surface 257 and the second conductive surface 258 may also have annular or cylindrical surfaces, and the first conductive surface 257 and the second conductive surface 258 are nested with each other to further increase the contact area therebetween, thereby improving the conductive stability.

[0103] like Figure 9 and 10 As shown in FIG, the first conductive member 251 is formed in the form of a first sleeve 253, which is sleeved on the connector 240. The first sleeve 253 is connected to the electric hook 211 and can rotate around the connector 240. The first conductive surface 257 of the first sleeve 253 is located on the outer surface of the first sleeve 253. The second conductive member 252 is formed in the form of a second sleeve 254, which is sleeved on the first sleeve 253 and connected to the power supply cable 230. The second conductive surface 258 is located on the inner surface of the second sleeve 254.

[0104] like Figure 12 and 13 As shown in FIG, the first sleeve 253 and the electric hook 211 can rotate synchronously around the connector 240. The second sleeve 254 is fixed to the power supply cable 230. The outer surface of the first sleeve 253 contacts the inner surface of the second sleeve 254, and the first sleeve 253 can rotate relative to the second sleeve 254.

[0105] In the above structure, the connection between the first sleeve 253 and the second sleeve 254 enables the connection between the electric hook 211 and the power supply cable 230 and also forms a rotatable support structure. In other words, the electric hook 211 can rotate relative to the power supply cable 230 while ensuring that the power supply cable 230 is not affected by the rotation of the electric hook 211 and maintaining the electrical connection between the power supply cable 230 and the electric hook 211. The first sleeve 253 is mounted on the connector 240 to allow for rotation, providing high stability. The second sleeve 254 is mounted on the first sleeve 253, which not only increases the contact area between the first conductive member 251 and the second conductive member 252, but also improves the connection strength between them.

[0106] See further Figure 10, which only shows the first sleeve 253 connected to the electric hook 211 and the second sleeve 254 connected to the power supply cable 230. It can be seen that the second sleeve 254 is sleeved on one end of the first sleeve 253, and the other end of the first sleeve 253 is not sleeved by the second sleeve 254, and the electric hook 211 is connected to the socket 255 formed on the other end of the first sleeve 253 (see Figure 9 Such a structure enables the second sleeve 254 to avoid obstruction to the electric hook 211 when the electric hook 211 rotates.

[0107] Similar to the connection method of the electric hook 211 on the first sleeve 253, the power supply cable 230 can also be fixed to the second sleeve 254 by inserting it into the hole or similar structure on the second sleeve 254, or the power supply cable 230 and the second sleeve 254 can be fixed together by welding or other methods consistent with existing technologies.

[0108] Optionally, a connection structure such as a bearing made of conductive material may be provided between the first sleeve 253 and the second sleeve 254 to improve the rotation performance of the first sleeve 253 relative to the second sleeve 254 .

[0109] Optionally, a stop structure may be provided between the first sleeve 253 and the second sleeve 254 to limit the rotation angle of the first sleeve 253 relative to the second sleeve 254. Such a stop structure can further limit the rotation angle of the electric hook 211, thereby resolving to some extent the problem of inconvenient control caused by excessive rotation of the electric hook 211.

[0110] like Figure 14 As shown in , optionally, a conductive connector 270 may be further provided between the first sleeve 253 and the second sleeve 254. One side of the conductive connector 270 contacts the outer surface of the first sleeve 253, and the other side of the conductive connector 270 contacts the inner surface of the second sleeve 254, thereby forming an electrical connection between the first sleeve 253 and the second sleeve 254.

[0111] The contact surface between the first sleeve 253 and the second sleeve 254 is an arcuate surface, which is difficult to machine. Furthermore, prolonged rotation of the first sleeve 253 relative to the second sleeve 254 can cause deformation, resulting in a gap between the first sleeve 253 and the second sleeve 254, which can degrade electrical contact between the two. The provision of the conductive connector 270 fills the gap between the first sleeve 253 and the second sleeve 254, thereby improving electrical contact efficiency between the first sleeve 253 and the second sleeve 254.

[0112] Further, if Figure 15As shown in FIG, the conductive connector 270 includes a sleeve portion 271 and a plurality of elastic springs 272 extending from one end of the sleeve portion 271. Thus, after installation, one end of the springs 272 elastically presses against the outer surface of the first sleeve 253, while the other end of the springs 272 is connected to the sleeve portion 271, which in turn presses against the inner surface of the second sleeve 254. This further improves the stability of the electrical connection between the first sleeve 253 and the second sleeve 254.

[0113] <Third embodiment>

[0114] Figures 16-21 The structure of a surgical tool 300 according to a third embodiment of the present invention is shown. Unless otherwise specified or conflicting, the specific structures described above with respect to the first and second embodiments also apply to the third embodiment. Detailed descriptions of structures identical or similar to those in the first and second embodiments will not be repeated. The following primarily describes structures in the third embodiment that differ from those in the first and second embodiments.

[0115] like Figure 16 As shown, the electric hook head of the surgical tool 300 of the third embodiment includes an electric hook 311, and its electric hook frame includes a first clamping member 320 and a second clamping member 330. The first clamping member 320 and the second clamping member 330 cooperate together to clamp and fix the electric hook 311 therebetween.

[0116] The first clamping member 320 and the second clamping member 330 are each provided with a snap-fitting groove 340 around their peripheries. Specifically, the snap-fitting groove 340 includes a first snap-fitting groove 341 provided on the first clamping member 320 and a second snap-fitting groove 342 provided on the second clamping member 330. When the first clamping member 320 and the second clamping member 330 are assembled together, the first snap-fitting groove 341 and the second snap-fitting groove 342 communicate with each other, forming a complete snap-fitting groove 340. The snap-fitting member 360 then snaps into the snap-fitting groove 340, specifically into the first snap-fitting groove 341 and the second snap-fitting groove 342 of the snap-fitting groove 340, to clamp the first clamping member 320 and the second clamping member 330 together.

[0117] If the electric hook 311 needs to be replaced, the hook 311 can be removed and replaced by simply removing the engaging member 360 from the engaging slot 340 and then separating the first clamping member 320 and the second clamping member 330. Therefore, the surgical tool 300 is very convenient to disassemble and assemble, and the replacement efficiency of the electric hook 311 is also effectively improved.

[0118] Figure 18A schematic perspective view of a snap-fitting member 360 is shown. The snap-fitting member 360 includes a connecting portion 361, which is connected between a first snap-fitting portion 362 and a second snap-fitting portion 363. The first snap-fitting portion 362 and the second snap-fitting portion 363, together with the connecting portion 361, form a U-shaped or C-shaped structure. A gap 369 is formed between the first snap-fitting portion 362 and the second snap-fitting portion 363, with the first snap-fitting portion 362 and the second snap-fitting portion 363 forming left and right sides of the gap 369, respectively, and being clamped in the snap-fitting slot 340 from both sides.

[0119] like Figure 19 As shown, the first engaging groove 341 of the first clamping member 320 has a first engaging wall 371, and the second engaging groove 342 of the second clamping member 330 has a second engaging wall 372. When the engaging member 360 is engaged with the engaging groove 340, the first engaging portion 362 contacts the first engaging wall 371, and the second engaging portion 363 contacts the second engaging wall 372, thereby splicing the first clamping member 320 and the second clamping member 330 together from the left and right sides.

[0120] Back to Figure 18 The first engaging portion 362 is connected to the connecting portion 361 and protrudes toward the second engaging portion 363 to form a protrusion that faces the inside of the engaging member 360. The first engaging portion 362 abuts against the engaging groove 340 via this protrusion. Similarly, the second engaging portion 363 also has a protrusion that faces the inside of the engaging member 360 and toward the first engaging portion 362. This helps to increase the clamping force of the engaging member 360 on the first clamping member 320 and the second clamping member 330.

[0121] Further as Figure 18 As shown, a first guide slope 364 is formed at one end of the first engaging portion 362 facing away from the connecting portion 361, for guiding the first engaging portion 362 to engage in the engaging groove 340. Similarly, a second guide slope 366 is formed at one end of the inward connecting portion 361 of the second engaging portion 363, for guiding the second engaging portion 363 to engage in the engaging groove 340. On the other hand, during the process of assembling the engaging member 360 into the engaging groove 340, the first guide slope 364 and the second guide slope 366 contact the engaging groove 340 and respectively guide the first clamping member 320 and the second clamping member 330 into the interior of the engaging member 360.

[0122] Preferably, the clamping member 360 is made of an elastic material, so that the first clamping member 320 and the second clamping member 330 can be easily guided into the clamping member 360. In addition, by arranging the first clamping portion 362 and the second clamping portion 363 relative to each other, they clamp the first clamping member 320 and the second clamping member 330 together from the left and right sides.

[0123] Optionally, a protrusion is formed in the middle portion of the connecting portion 361. When the snap-fitting member 360 is snap-fitted into the snap-fitting slot 340, the protrusion of the connecting portion 361 abuts against the snap-fitting slot 340 and against the first snap-fitting wall 371 or the second snap-fitting wall 372. Thus, the protrusion of the connecting portion 361, the protrusion of the first snap-fitting portion 362, and the protrusion of the second snap-fitting portion 363 contact the snap-fitting slot 340 from three directions, thereby enabling better clamping of the first snap-fitting portion 362 and the second snap-fitting portion 363.

[0124] In other words, the multiple protrusions circumferentially abut the bottom of the engaging groove 340 from multiple directions, preventing the first clamping member 320 and the second clamping member 330 from separating from each other. Furthermore, the number of protrusions is not limited to the structure disclosed above, and more protrusions can be provided. Increasing the number of protrusions helps improve the clamping effect of the first clamping member 320 and the second clamping member 330.

[0125] Further optionally, the first engaging portion 362 may have a first top surface 365 located at the top of the protrusion. Similarly, the protrusion of the second engaging portion 363 may have a second top surface 367, and the protrusion of the connecting portion 361 may have a third top surface 368. The angle between the first top surface 365 and the first guide slope 364 may be between 30 and 60 degrees. Similarly, the angle between the second top surface 367 and the second guide slope 366 may also be between 30 and 60 degrees. Optionally, at least one of the first top surface 365 and the second top surface 367 may be a dome.

[0126] The first top surface 365 and the second top surface 367 help to increase the contact area with the snap-fitting groove 340 to provide a better clamping effect.

[0127] In an optional structure, the thickness of at least a portion of the first engaging portion 362 on a side near the connecting portion 361 is less than the thickness of the connecting portion 361 and the top of the first engaging portion 362. Similarly, the thickness of at least a portion of the second engaging portion 363 on a side near the connecting portion 361 is less than the thickness of the connecting portion 361 and the top of the second engaging portion 363. By reducing the thickness of the connection portion between the first engaging portion 362 and the connecting portion 361 and the connection portion between the second engaging portion 363 and the connecting portion 361, the first engaging portion 362 and the second engaging portion 363 can be made more elastic, thereby facilitating adjustment of the opening size of the gap 369 so as to facilitate clamping the first clamping member 320 and the second clamping member 330 in the engaging member 360.

[0128] Alternatively, the thickness of the first engaging portion 362 on the side near the connecting portion 361 gradually increases from the smallest thickness portion toward the connecting portion 361 and the first engaging portion 362. Similarly, the thickness of the second engaging portion 363 on the side near the connecting portion 361 gradually increases from the smallest thickness portion toward the connecting portion 361 and the second engaging portion 363. This ensures that the engaging member 360 is not easily deformed while maintaining good elasticity, thereby improving the stability and structural strength of the engaging member 360.

[0129] From the top of the first engaging portion 362 to the portion connected to the connecting portion 361 , the wall surface of the first engaging portion 362 facing the engaging groove 340 is formed as a part of the inner surface of the hollow cylinder, so that the first engaging portion 362 can have better elasticity.

[0130] like Figure 19 As shown, the engaging member 360 further includes a third engaging portion 362' on its upper surface and a fourth engaging portion 363' on its lower surface. Correspondingly, the engaging slot 340 further includes a third engaging wall 373 and a fourth engaging wall 374 on the upper and lower sides of the engaging slot 340, respectively.

[0131] exist Figure 16 In the assembled state of the engaging member 360 shown, the third engaging portion 362 ′ contacts the third engaging wall 373 , and the fourth engaging portion 363 ′ contacts the fourth engaging wall 374 , thereby increasing the clamping force on the first clamping member 320 and the second clamping member 330 .

[0132] By the contact between the third snap-fitting part 362' and the third snap-fitting wall 373 and the contact between the fourth snap-fitting part 363' and the fourth snap-fitting wall 374, the holding force of the snap-fitting component 360 in the snap-fitting groove 340 is increased, thereby achieving the limiting effect on the first clamping member 320 and the second clamping member 330, specifically limiting the displacement of the first clamping member 320 and the second clamping member 330 in the up and down directions.

[0133] As in Figure 17 As schematically shown in FIG, the snap-fitting member 360 optionally includes at least two snap-fitting member units, the number of which can be selected according to the thickness of the snap-fitting groove 340, and which are overlapped with each other.

[0134] Figure 20 and 21 The specific structures of the first clamping member 320 and the second clamping member 330 are shown respectively. The first clamping member 320 has a matching groove 321, and further has a first installation groove 322 and an avoidance groove 323. The first installation groove 322 is connected to the avoidance groove 323.

[0135] The second clamping member 330 is provided with a connecting block 331 and a second mounting groove 332. When the first clamping member 320 and the second clamping member 330 are assembled together, the connecting block 331 fits into the matching groove 321. Specifically, the connecting block 331 is embedded in the matching groove 321, thereby ensuring that the first clamping member 320 and the second clamping member 330 can be assembled stably. The engagement between the connecting block 331 and the matching groove 321 also helps to determine the engagement angle between the first clamping member 320 and the second clamping member 330, thereby improving the installation efficiency and stability of the first clamping member 320 and the second clamping member 330.

[0136] Optionally, an interlocking structure may be provided between the connecting block 331 and the matching groove 321 to further improve the assembly stability of the first clamping member 320 and the second clamping member 330 .

[0137] In addition, the second mounting groove 332 cooperates with the first mounting groove 322 to form a clamping cavity, which clamps and fixes the electric hook 311 therein.

[0138] A stop block 324 is provided in one of the first installation slot 322 and the second installation slot 332 . The stop block 324 is used to cooperate with the stop slot 312 in the electric hook 311 , thereby limiting the circumferential and radial movements of the electric hook 311 .

[0139] By providing the stop block 324, the axial and radial movement of the electric hook 311 is limited, that is, the electric hook 311 cannot be displaced in the first installation groove 322 and the second installation groove 332, nor can it be displaced along its radial direction, thereby helping to improve the installation stability and conductive performance of the electric hook 311, and further improving the working stability of the surgical tool 300.

[0140] Further Figure 20 As shown, one side of the stop block 324 is arc-shaped and matches the bottom of the first mounting slot 322, while the other side is flat. One side of the flat shape abuts against the stop slot 312 on the electric hook 311 to prevent the electric hook 311 from rotating in the first mounting slot 322.

[0141] At the same time, the stop block 324 is fixedly connected to the first mounting groove 322 of the first clamping member 320, for example, by welding, bonding or other fixing methods known in the art.

[0142] The length of the first mounting groove 322 is substantially the same as that of the stop groove 312, thereby fixing the electric hook 311 in the axial direction and preventing axial displacement. Therefore, by providing the first mounting groove 322, the electric hook 311 can be positioned in both the axial and radial directions.

[0143] A relief groove 323 is provided at one end of the first mounting groove 322. The diameter of the relief groove 323 may be larger than that of the first mounting groove 322. During installation of the electric hook 311, the relief groove 323 provides space for the electric hook 311, facilitating its proper placement. Furthermore, the relief groove 323 secures one end of the electric hook 311. During removal and replacement of the electric hook 311, the first clamping member 320 and the second clamping member 330 can be separated. At this point, one end (e.g., the lower end) of the electric hook 311 is inserted into the relief groove 323. This prevents the electric hook 311 from accidentally falling, and allows the operator to easily pull the electric hook 311 out of the relief groove 323.

[0144] Alternatively, as Figure 20 As shown, one side of the first clamping member 320 is formed into an L-shape. This L-shaped structure provides a support surface 325. When assembling the first clamping member 320 and the second clamping member 330, the second clamping member 330 can be placed on the support surface 325 to facilitate the connection between the first clamping member 320 and the second clamping member 330. The provision of the support surface 325 can limit the relative movement between the first clamping member 320 and the second clamping member 330 along the axial direction, thereby preventing their positions from being misaligned during assembly, thereby improving assembly accuracy.

[0145] Further optional, such as Figure 16 and 17 As shown, surgical tool 300 further includes a first stop rod 351 and a second stop rod 352. The first stop rod 351 is disposed in first clamping member 320 and extends through first engaging slot 341. When engaging member 360 is engaged with engaging slot 340, its first guide slope 364 abuts against the first stop rod 351. Similarly, the second stop rod 352 is disposed in second clamping member 330 and extends through second engaging slot 342. The second guide slope 366 of engaging member 360 abuts against the second stop rod 352.

[0146] The first stopper rod 351 and the second stopper rod 352 restrict the installation position of the engaging member 360 from both sides, preventing the engaging member 360 from rotating circumferentially within the engaging groove 340. More specifically, the first clamping member 320 is provided with a first insertion hole 326 extending along its axial direction, into which the first stopper rod 351 is inserted. Similarly, the second clamping member 330 is provided with a second insertion hole 333 extending along its axial direction, into which the first stopper rod 351 is inserted.

[0147] Alternatively, the first stop rod 351 and the second stop rod 352 may be threaded rods, and the first insertion hole 326 and the second insertion hole 333 may be threaded holes, and the first stop rod 351 and the second stop rod 352 may be screwed into the first insertion hole 326 and the second insertion hole 333, respectively. This threaded connection form provides a detachable first stop rod 351 and the second stop rod 352.

[0148] <Fourth embodiment>

[0149] Figures 22-27 The structure of a surgical tool 400 according to a fourth embodiment of the present invention is shown. Unless otherwise specified or conflicting, the specific structures described above with respect to the first to third embodiments also apply to the fourth embodiment. Detailed descriptions of structures identical or similar to those in the first to third embodiments will not be repeated. The following primarily describes structures in the fourth embodiment that differ from those in the first to third embodiments.

[0150] Figure 22 A schematic perspective view of a surgical tool 400 according to a fourth embodiment is shown. The surgical tool 400 includes an electric hook head 410 and a socket assembly 420. The electric hook head 410 includes an electric hook 411 and an electric hook frame 412. The electric hook 411 is received and secured within the electric hook frame 412. The electric hook head 410 is movably connected to the socket assembly 420 via a connector 440. For example, the electric hook head 410 is rotatable relative to the socket assembly 420.

[0151] In this embodiment, a receiving cavity 460 is formed between the electric hook head 410 and the socket assembly 420 , and the power supply cable 430 extends from the socket assembly 420 toward the electric hook head 410 through the receiving cavity 460 and is connected to the electric hook 411 to supply power to the electric hook 411 .

[0152] from Figure 23 As can be more clearly seen in the exploded perspective view, the electric hook frame 412 has a pair of first connecting arms 413 formed at one end (e.g., the lower end in the figure), with a receiving cavity 460 formed between the pair of first connecting arms 413. The support assembly 420 has a pair of second connecting arms 421 formed at one end (e.g., the upper end in the figure), and the second connecting arms 421 are arranged corresponding to the first connecting arms 413.

[0153] Further references Figure 23As can be seen, the connecting member 440 includes a first connecting member 441 and a second connecting member 442, which are coaxially arranged with each other. One of the pair of first connecting arms 413 is connected to the corresponding second connecting arm 421 via the first connecting member 441, and the other first connecting arm 413 is connected to the corresponding other second connecting arm 421 via the second connecting member 442, thereby achieving a movable connection between the electric hook head 410 and the socket assembly 420. After the connection is completed, the aforementioned receiving cavity 460 is formed between the electric hook head 410 and the socket assembly 420.

[0154] The accommodating cavity 460 provides a space for bending the power supply cable 430. Moreover, after being connected, a gap exists between the first connecting member 441 and the second connecting member 442 in the accommodating cavity 460 for the power supply cable 430 to pass through.

[0155] Optionally, as mentioned above in the second embodiment, a wheel 414 is further provided on the electric hook frame 412 as a driven component. The rotation axis of the wheel 414 is set to be consistent with the rotation axis of the connecting member 440. By rotating the wheel 414, the connecting member 440 can be driven to rotate, thereby realizing the rotation of the electric hook head 410 relative to the support assembly 420.

[0156] In this embodiment, a bending-resistant structure 450 is disposed within the receiving cavity 460. Specifically, the bending-resistant structure 450 is disposed on the socket assembly 420. When the electric hook head 410 moves relative to the socket assembly 420, causing the power cable 430 to bend, the bending-resistant structure 450 supports and guides the bent power cable 430, preventing damage or even breakage of the power cable 430 due to excessive bending. Therefore, the bending-resistant structure 450 and the receiving cavity 460 that accommodates the bending-resistant structure 450 in the fourth embodiment together constitute a cable connection retention mechanism.

[0157] The anti-bending structure 450 can guide the power supply cable 430 to bend along its surface to adapt to the frequent rotation operations of the electric hook 411, ensure its stability when the power supply cable 430 is bent, and prevent it from being entangled or shifted during the bending process, thereby improving the overall operational performance of the surgical tool 400.

[0158] Go to Figure 24 and 25 One embodiment of the anti-bending structure 450 includes two support blocks arranged opposite to each other with a spacing of 180 degrees, and a supporting arc surface 451 is formed on the top of each support block. The supporting arc surface 451 is preferably in the form of a convex surface so as to support and guide the curved power supply cable 430.

[0159] The supporting curved surface 451 can support the bending of the power supply cable 430 to prevent the power supply cable 430 from bending excessively, and can guide the power supply cable 430 to bend along the curvature direction of the supporting curved surface 451, thereby maintaining the stability of the power supply cable 430 during the bending process, thereby reducing or eliminating the risk of the power supply cable 430 shifting during the bending process.

[0160] Optionally, a groove or a concave surface may be formed in the supporting arc surface 451 along the extending direction of the power supply cable 430. When the power supply cable 430 is bent and abuts against the supporting arc surface 451, the deflection of the power supply cable 430 may be limited.

[0161] Figure 25 FIG4 shows another embodiment of a bending-resistant structure 450. The bending-resistant structure 450 includes a plurality of vertically extending supports 452 having different heights. Specifically, the heights of the supports 452 increase from the inside to the outside of the seat assembly 420, so that the tops of the supports 452 form an arc similar to the arcuate support surface 451 described above, thereby supporting and guiding the curved power supply cable 430.

[0162] By adjusting the height and number of the supporting members 452 , the curvature of the supporting arc surface can be adjusted to accommodate various types of power supply cables 430 .

[0163] Optionally, the width of the support member 452 (the dimension perpendicular to the paper, or the dimension along the extension direction of the connector 440) is greater than or equal to the diameter of the power cable 430 to ensure that the support member 452 can adequately support the power cable 430 and prevent the power cable 430 from shifting due to bending. Furthermore, optionally, a groove may be formed on the top of the support member 452 to accommodate and restrain the power cable 430.

[0164] Figure 27 Another embodiment of a bending-resistant structure 450 is shown. The bending-resistant structure 450 includes an elastic bending member 453. When the power cable 430 bends and rests against the elastic bending member 453, the elastic bending member 453 deforms, specifically elastically deforms, and the elastically deformed elastic bending member 453 can exert a bending-resistant force on the power cable 430.

[0165] The elastic bending member 453 has elastic recovery ability, and can apply anti-bending force to the power supply cable 430 when bending, thereby preventing the power supply cable 430 from bending excessively. At the same time, it can also provide guidance for the bent power supply cable 430 to ensure that the power supply cable 430 bends smoothly.

[0166] Similar to the supporting member 452 , the width of the elastic bending member 453 should also be greater than or equal to the diameter of the power supply cable 430 , and preferably, a groove may also be formed on the top of the elastic bending member 453 for accommodating the power supply cable 430 .

[0167] Optionally, a pressure detection unit (e.g., a pressure sensor, not shown) may be provided on the elastic bending member 453. The pressure detection unit may be connected to a control terminal (not shown) of the surgical tool 400 to detect the pressure on the elastic bending member 453. Based on the detected pressure, the control terminal may control the drive system of the surgical tool 400. For example, when the detected pressure on the elastic bending member 453 exceeds a predetermined threshold, the control terminal may control the drive system to drive the electric hook head 410 to rotate relative to the support assembly 420 to reduce the degree of bending of the power supply cable 430.

[0168] <Fifth embodiment>

[0169] Figures 28-31 A surgical tool 500 according to a fifth embodiment of the present invention is shown. Unless otherwise specified or conflicting, the specific structures described above with respect to the first to fourth embodiments also apply to the fifth embodiment. Detailed descriptions of structures identical or similar to those in the first to fourth embodiments will not be repeated. The following will primarily describe structures in the fifth embodiment that differ from those in the first to fourth embodiments.

[0170] Figure 28 A perspective view of a surgical tool 500 is shown. The surgical tool 500 includes an electric hook head 510 and a socket assembly 520. The electric hook head 510 can, for example, rotate relative to the socket assembly 520 as in the previous embodiments. The electric hook head 510 includes an electric hook 511 and an electric hook frame 512. The electric hook 511 is fixedly mounted in the electric hook frame 512, so that the electric hook 511 can rotate relative to the socket assembly 520, driven by the electric hook frame 512.

[0171] The surgical tool 500 also includes a power supply cable 513, which extends into the electric hook frame 512 and is electrically connected to the electric hook 511 to supply power to the electric hook 511. The electric hook 511 and the power supply cable 513 can be made of a metallic conductive material. Preferably, the electric hook 511 and the power supply cable 513 are made of the same conductive material. Of course, depending on the specific application, the electric hook 511 and the power supply cable 513 can also be made of different materials.

[0172] In the present application, the electric hook 511 and the power supply cable 513 are fixedly connected together by means of crimping, so that the electric hook 511 and the power supply cable 513 are formed into one body. Figure 29 shown.

[0173] Furthermore, the electric hook 511 and the power supply cable 513 are formed into one piece by crimping and the electric hook frame 512 is formed into one piece. The electric hook frame 512 is made of insulating materials such as plastic, resin, etc. Figure 30 As shown, after the electric hook 511 and the power supply cable 513 are formed into one body, the electric hook 511 and the power supply cable 513 are placed in a mold 530, and the electric hook frame 512 is formed by injection molding. The electric hook 511 and the power supply cable 513 formed into one body are covered in the molded electric hook frame 512. After injection molding, the mold 530 is removed to obtain an integrated electric hook head 510, as shown in FIG. Figure 31 Preferably, at least the connection portion between the electric hook 511 and the power supply cable 513 is enclosed in an electric hook frame 512 made of insulating material.

[0174] The resulting integrated electric hook head 510 has greater structural stability. The electric hook 511 and the power cable 513 are integrally connected by crimping or other means. During operation, the power cable 513 will not easily become detached from the electric hook 511 as the electric hook 511 rotates, thereby improving the stability of the electrical connection between the power cable 513 and the electric hook 511. Furthermore, the electric hook frame 512 is integrally formed with the electric hook 511 and the power cable 513 by injection molding. As a result, the resulting electric hook head 510 lacks the gaps that occur during assembly of conventional electric hook heads. This helps reduce the risk of bacterial growth and improves the reliability of sterilizing the electric hook head 510 after a single use.

[0175] In the above description, the electric hook head 510 with the electric hook 511 is used as an example. Those skilled in the art will appreciate that the above structure is also applicable to other types of surgical tools, such as electric shovels and other tools that require high current for surgical operations, which are also within the scope of this application.

[0176] The above describes several exemplary embodiments of the surgical tool of the present application. These embodiments are merely examples of implementations of the present application and do not limit the scope of the present application. Those skilled in the art can make various modifications and variations to the embodiments based on the disclosed structure, and combine the features disclosed in the embodiments, and such modifications, variations, and combinations are within the scope of the present application.
