Description

Technical Field

[0001] This invention relates to a surgical instrument, and more specifically, to an ultrasonic surgical device. Background Technology

[0002] An ultrasonic scalpel is essentially an instrument that further amplifies the ultrasonic vibrations obtained through a piezoelectric transducer (which transmits electrical energy to the transducer via an energy generator, and the transducer converts the electrical energy into ultrasonic mechanical energy). The amplified ultrasonic vibrations are then used by the head of the scalpel to cut and coagulate soft tissues. Clinically, this instrument can achieve lesion removal at lower temperatures and with less bleeding.

[0003] The existing ultrasonic scalpel blade assembly has a core blade, an inner sleeve, an outer sleeve, and a handle connected to the core blade. The inner sleeve is located between the core blade and the outer sleeve and can move a certain distance along the axis to open or close the movable chuck, so that the movable chuck contacts or separates from the end of the core blade, thereby clamping the target biological tissue and facilitating subsequent cutting.

[0004] In this connection method, the ends of both the inner and outer sleeves come into contact with biological tissue, which can then enter the gap between the ends of the inner and outer sleeves. Cleaning is very troublesome, and generally, the entire ultrasonic scalpel can only be discarded after surgery, greatly increasing the cost of using the ultrasonic scalpel. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide an ultrasonic surgical device that, through the arrangement of two semi-circular tubes, a disassembly lever, and a core blade rod, allows the cannula to be disassembled after use, and the disassembly lever and core blade rod to be removed for cleaning. This facilitates the cleaning operation, enables the reuse of the surgical scalpel, and reduces application costs.

[0023] And a snap-fit ​​block, which is located at the bottom of the connecting block near the housing side. The snap-fit ​​block can be inserted into the snap-fit ​​groove along with the connecting block and can slide towards the housing side to embed into the snap-fit ​​groove and cooperate with the snap-fit ​​groove. When the snap-fit ​​block cooperates with the snap-fit ​​groove, the side of the connecting block near the housing is in contact with the side of the disassembly groove near the housing, and at this time the two ends of the top semicircular tube and the bottom semicircular tube are aligned.

[0024] The present invention is further configured such that two semicircular rings are fixedly connected to the outer side of the two semicircular tubes near the outer shell.

The housing is hollow inside and has a fixed handle 11 fixedly connected to its bottom. The blade assembly 2 is connected to the housing. The sleeve assembly 3 is fixedly connected to the housing. The blade assembly 2 includes a piezoelectric converter 21, a fixing rod 23, and a core blade 22. The piezoelectric converter 21 is fixedly connected to the rear end of the housing. The fixing rod 23 is fixedly connected inside the housing 1 and one end extends out of the housing 1. One end of the core blade 22 is detachably connected to the end of the fixing rod 23 extending out of the housing 1, and the other end is a blade head. The sleeve assembly 3 includes a semi-circular tube 31, a connecting component, a movable clamp head 6, a fixed pull rod 33, and a disassembly pull rod 32. Two semicircular tubes 31 are provided, and the two semicircular tubes 31 can form a complete circular tube; the connecting assembly connects the two semicircular tubes 31 together and connects the two semicircular tubes 31 to the outer shell; the movable clamp head 6 is located at the end of the top semicircular tube 31 away from the shell 1; the fixed pull rod 33 is located in the shell 1 and one end extends out of the shell 1; one end of the disassembly pull rod 32 is detachably connected to the fixed pull rod 33, and the other end is connected to the movable clamp head 6. The pull rod slides along the length of the semicircular tube 31 to drive the movable clamp head 6 to clamp and loosen with the blade head of the core knife rod 22; a wrench 12 is rotatably connected to the bottom of the shell 1. The wrench 12 pushes the fixed pull rod 33 by rotation to drive the interactive pull rod to slide. Specifically, an activation button is provided on the shell 1, which is used to control the switch of the piezoelectric converter 21. The disassembly pull rod 32 and the core knife rod 22 pass through the circular tube formed by the two semicircular tubes 31.

[0058] When the surgical device is in use, the semi-circular tube 31, movable forceps head 6, disassembly lever 32, and core blade rod 22 will come into direct contact with biological tissue. After use, the two semi-circular tubes 31 can be separated from each other, and the disassembly lever 32 and core blade rod 22 can be removed from the fixed lever 33 and fixed rod 23 respectively, so as to facilitate the cleaning of each part and enable the surgical device to be reused.

[0059] Specifically, the two semicircular tubes 31 are divided into a top semicircular tube 31 and a bottom semicircular tube 31; several disassembly mechanisms are provided between the top semicircular tube 31 and the bottom semicircular tube 31, and the multiple disassembly mechanisms are arranged along the axial direction of the semicircular tube 31. Each disassembly mechanism includes two disassembly components, which are located on both sides of the inner wall of the semicircular tube 31 respectively; the disassembly components include a disassembly groove 313, a snap-fit ​​groove 314, a connecting block 315, and a snap-fit ​​block 316. The disassembly groove 313 is located at the top of the bottom semicircular tube 31; the snap-fit ​​groove 314 is located at the bottom of the disassembly groove 313 near the housing 1; the connecting block 315 is fixed. Connected to the bottom of the top semicircular tube 31, the connecting block 315 can be vertically inserted into the disassembly groove 313; the snap-fit ​​block 316 is located at the bottom of the connecting block 315 near the housing 1. The snap-fit ​​block 316 can be inserted into the snap-fit ​​groove 314 along with the connecting block 315 and can slide towards the housing 1 to embed into the snap-fit ​​groove 314 and cooperate with the snap-fit ​​groove 314. When the snap-fit ​​block 316 cooperates with the snap-fit ​​groove 314, the side of the connecting block 315 near the housing 1 is in contact with the side of the disassembly groove 313 near the housing 1, and at this time, the two ends of the top semicircular tube 31 and the bottom semicircular tube 31 are aligned.

[0060] When the two semicircular tubes 31 are joined together, the snap-fit ​​block 316 on the top semicircular tube 31 is aligned with the corresponding disassembly groove 313. Then, the snap-fit ​​block 316 and the connecting block 315 are inserted downwards into the disassembly groove 313. Then, the top semicircular tube 31 is pushed to move so that the snap-fit ​​block 316 is inserted into the snap-fit ​​groove 314, so that the two semicircular tubes 31 form a complete circular tube.

[0061] Specifically, two semicircular rings 312 are fixedly connected to the outer side of the two semicircular tubes 31 near the outer shell; a connecting pipe 4 is fixedly connected to the end of the shell 1 near the two semicircular tubes 31, and the two semicircular tubes 31 are detachably connected to the connecting pipe 4; the connecting assembly includes a connecting sleeve 5 and a limiting ring 51, the connecting sleeve 5 is threaded to the outside of the connecting pipe 4; the limiting ring 51 is fixedly connected to the inner side of the semicircular tube 31 away from the shell 1, the limiting ring 51 is sleeved on the outside of the two semicircular tubes 31, and the inner diameter of the limiting ring 51 is equal to the outer diameter of the semicircular ring 312; the outer diameter of the semicircular ring 312 is equal to the outer diameter of the connecting pipe 4.

[0062] After the two semicircular tubes 31 are assembled into a complete circular tube, the end of the circular tube near the semicircular ring 312 is pressed against the connecting tube 4. Then, the connecting sleeve 5 is fitted over the two semicircular rings 312 and threaded onto the connecting tube 4. When the connecting sleeve 5 is tightened, the limiting ring 51 presses the semicircular ring 312 and the semicircular tube 31 onto the connecting tube 4. Under the limiting of the connecting sleeve 5, the two semicircular tubes 31 that make up a complete circular tube are not easy to separate from each other.

[0063] Specifically, one end of the fixing rod 23 extending out of the housing 1 is located inside the connecting tube 4, and the end of the fixing rod 23 near the core knife rod 22 is provided with a connecting rod 231 that is inserted into the core knife rod 22 and threadedly connected to the core knife rod 22.

[0064] Specifically, the connection between the fixed pull rod 33 and the disassembly pull rod 32 is located inside the connecting pipe 4 and is detachably connected together by the fixing assembly 7; the fixed pull rod 33 has two rotating grooves 321 on both sides near the end of the disassembly pull rod 32, and the disassembly pull rod 32 has two connecting grooves 317 on the outer side near the end of the fixed pull rod 33, and the two connecting grooves 317 have a groove 318 on the side of the two connecting grooves 317 that are close to each other at the end away from the fixed pull rod 33; the fixing assembly 7 includes a rotating rod 71 and a protrusion 711, and there are two rotating rods 71, which rotate respectively. Connected within two rotating grooves 321, the rotation axis of the rotating rod 71 is vertical, and the ends of the two rotating rods 71 ​​away from the housing 1 can respectively extend into the two connecting grooves 317; two protrusions 711 are fixedly connected to the two sides of the two rotating rods 71 ​​that are close to each other, and the two protrusions 711 are located at one end of the housing 1 of the rotating rod 71, and the two protrusions 711 can respectively be inserted into the two grooves 318; two elastic elements are provided in the two rotating grooves 321, and the two elastic elements act on the ends of the two rotating rods 71 ​​that are close to the housing 1 and apply elastic forces to the two rotating rods 71 ​​in mutually distancing directions.

[0065] The two protrusions 711 and the two grooves 318 can be used to connect the fixed pull rod 33 and the disassembly pull rod 32 together.

[0066] Specifically, the side of the protrusion 711 furthest from the housing 1 is set to be arc-shaped;

[0067] Specifically, the top of the connecting pipe 4 is provided with a vertical clearance hole 41 penetrating the top sidewall of the connecting pipe 4. A sliding block 8 is provided inside the clearance hole 41, and the sliding block 8 slides along the axis of the connecting pipe 4 within the clearance hole 41. Two disassembly rods 81 are fixedly connected to the bottom of the sliding block 8. When the two protrusions 711 are respectively embedded into the two grooves 318, the sides of the two disassembly rods 81 that are close to each other are aligned with the sides of the two rotating rods 71 ​​that are far away from each other. Two disassembly blocks 712 are fixedly connected to the ends of the two rotating rods 71 ​​that are far away from each other and close to the housing 1. The side of the disassembly block 712 that is far away from the housing 1 is set as an inclined surface, and the two inclined surfaces that are far away from each other are inclined towards the direction close to the housing 1. The rotation axis of the rotating rod 71 is located on the side of the disassembly block 712 that is far away from the housing 1.

[0068] Sliding the sliding block 8 toward the direction of the housing 1 can drive the two disassembly rods 81 to slide toward the direction of the housing 1. When the two disassembly rods 81 contact the two inclined surfaces on the two disassembly blocks 712, they can push the two ends of the two rotating rods 71 ​​near the housing 1 to rotate toward each other, thereby driving the two ends of the two rotating rods 71 ​​away from the housing 1 to rotate toward each other, thereby causing the two protrusions 711 to disengage from the two grooves 318 respectively, thus realizing the disassembly of the fixed pull rod 33 and the disassembly pull rod 32.

[0069] Specifically, a mounting groove 311 is provided on the top of the semi-circular tube 31 at the end away from the housing 1, and support blocks 61 are respectively located on both sides of the semi-circular tube 31 in the mounting groove 311; two coaxial rotating shafts 62 are fixedly connected to both sides of the movable pliers head 6, and the axes of the two rotating shafts 62 are horizontal and perpendicular to the axis of the semi-circular tube 31. A guide hole 611 is provided on the support block 61, which passes through the support block 61 along the axis of the rotating shaft 62. The rotating shaft 62 slides in the guide hole 611, and the height of the rotating shaft 62 gradually decreases as it slides from away from the housing 1 to closer to the housing 1 in the guide hole 611; the end of the movable pliers head 6 close to the housing 1 is hinged to the end of the disassembly lever 32 away from the housing 1.

[0070] With the guide hole 611, when the disassembly lever 32 slides away from the housing 1, the movable pliers 6 rotates upward away from the housing 1 and moves away from the cutter head. When the disassembly lever 32 moves towards the housing 1, the movable pliers 6 moves downward away from the housing 1 and moves closer to the cutter head.

[0071] Specifically, when the disassembly lever 32 moves to the position furthest from the housing 1, the two disassembly rods 81 at the bottom of the sliding block 8, which are attached to the side of the clearance hole 41 away from the housing 1, are located on the side of the disassembly block 712 away from the housing 1 and do not contact the disassembly block 712, thereby ensuring that the disassembly lever 32 will not detach from the fixed lever 33 during the sliding process of the disassembly lever 32.

[0072] Specifically, an elastic element is provided in the clearance hole 41. The elastic element is located on the side of the sliding block 8 near the housing 1 and is in a compressed state.

[0073] Specifically, a slider 34 is fixedly connected to one end of the fixed pull rod 33 inside the housing 1. The slider 34 can slide within the housing 1 along the length of the fixed pull rod 33. Two coaxial fixed shafts 341 are fixedly connected to both sides of the slider 34. The axis of the fixed shafts 341 is horizontal and perpendicular to the length of the fixed pull rod 33. Control plates 121 located on both sides of the slider 34 are fixedly connected to the top of the wrench 12. Two control holes 122 are provided on the control plates 121 respectively, which are elongated holes along the axis of the fixed shafts 341. An elastic element is provided between the wrench 12 and the fixed handle 11, and the elastic element is in a compressed state, so that the movable pliers head 6 and the cutting head are clamped when no external force is applied.

[0074] Specifically, several supporting circular plates are provided inside the circular tube composed of the connecting pipe 4 and the two semi-circular pipes 31. The supporting circular plates are set as flexible supporting circular plates. The disassembly rod 32 and the core knife rod 22 pass through multiple supporting circular plates, and the outer side of the supporting circular plates is in contact with the inner wall of the semi-circular pipe 31 or the connecting pipe 4.
