Description

Technical Field

[0001] The utility model relates to the technical field of electrosurgical operating instruments, and more particularly to an integrated rod clamp structure with a detachable cutting blade and a high-frequency operating instrument. Background Art

[0002] Bipolar coagulation forceps is a commonly used hemostatic tool. The front end of the bipolar coagulation forceps is equipped with two clamp heads, which are connected to a power source respectively. When in use, the forceps are operated so that the two clamp heads come into contact with the wound. Under the action of high-frequency current, local high temperature is generated at the wound, heating the bleeding tissue to cause protein coagulation, and the blood vessel lumen becomes smaller or blocked to achieve the effect of hemostasis.

[0003] In related fields, bipolar coagulation forceps are usually disposable medical devices. With the development of equipment and related processes for cleaning, disinfection and sterilization of medical devices, bipolar coagulation forceps can meet corresponding reuse standards after cleaning, disinfection and sterilization.

Furthermore, currently used cutting blades are typically designed for single use. If reused multiple times, they can become damaged, affecting cutting performance. However, the lifespan of components like the head and shaft is significantly longer than that of the cutting blades. Replacing the head and shaft along with damaged cutting blades significantly increases operating costs. Utility Model Content

DETAILED DESCRIPTION

[0026] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments.

[0027] Reference Figure 1 The high-frequency surgical instrument provided in this embodiment may include a housing assembly 1, a rod assembly 2, an actuator assembly 3, and a control assembly 4. The control assembly 4 is located within the housing assembly 1, the rod assembly 2 is at least partially located within the housing assembly 1, the actuator assembly 3 is disposed at the distal end of the rod assembly 2, i.e., the end of the rod assembly 2 away from the housing assembly 1, and the actuator assembly 3 includes a clamp consisting of two clamp heads that can move relatively close to or away from each other; the portion of the rod assembly 2 located within the housing assembly 1 cooperates with the control assembly 4 to achieve transmission coordination between the clamp and the control assembly 4.

[0028] In order to improve the safety and reliability of high-frequency surgical instruments, this embodiment provides an integrated rod clamp structure with a detachable cutting blade 221. Figure 2The integrated rod clamp structure of this embodiment includes a rod assembly 2 and an actuator assembly 3. The actuator assembly 3 is arranged at the distal end of the rod assembly 2, that is, the actuator assembly 3 is located at the end of the rod assembly 2 away from the housing assembly 1; the actuator assembly 3 includes two clamp heads, at least one of the two clamp heads can move relative to the other clamp head, which means that the two clamp heads of this embodiment can be a movable clamp head and a fixed clamp head, the fixed clamp head is connected to the rod assembly 2, the movable clamp head is hinged to the fixed clamp head, and the movable clamp head can rotate relative to the fixed clamp head; the two clamp heads can also be two movable clamp heads, both of which are hinged at the distal end of the rod assembly 2, and the two movable clamp heads can rotate synchronously relative to each other. At least one of the two clamp heads has a knife groove on its inner side, that is, only one clamp head can have a knife groove on the side facing the other clamp head, or both clamp heads can have a knife groove on their inner sides, and the knife grooves of the two clamp heads cooperate with each other.

[0029] Reference Figure 3 The rod assembly 2 includes a cutting mechanism 22, a clamp rod 21, and an outer rod 23. The cutting mechanism 22 is disposed within the clamp rod 21, and the outer rod 23 is sleeved on the clamp rod 21. The cutting mechanism 22, the clamp rod 21, and the outer rod 23 are sleeved sequentially from the inside out to form an integrated structure. The distal end of the clamp rod 21 can be transmission-connected to at least one of the two clamp heads. When the clamp rod 21 drives the clamp head transmission-connected thereto to rotate, the two clamp heads can move relatively away from or closer to each other, thereby enabling the two clamp heads to clamp tissue. The proximal end of the clamp rod 21 can be provided with a mounting portion 213, which can have a mounting hole.

[0030] Reference Figure 4 The cutting mechanism may include a knife bar and a cutting blade 221. The cutting blade 221 may be provided at the distal end of the knife bar, i.e., the end of the knife bar away from the housing assembly 1. The proximal end of the knife bar may be provided with a mounting structure, and the knife bar can slide relative to the mounting structure. The mounting structure is used to cooperate with the mounting portion 213 at the proximal end of the clamp rod 21, for example, it can be detachably mounted on the mounting portion 213.

[0031] Therefore, during the assembly process of the integrated rod clamp structure of this embodiment, the distal end of the cutting mechanism 22 can be inserted into the interior of the clamp rod 21 through the mounting hole, and then the cutting mechanism can be connected to the clamp rod 21 through the cooperation of the mounting structure and the mounting portion 213. At this time, the proximal end of the knife rod can be exposed and set with the proximal end of the clamp rod 21. By pushing the proximal end of the knife rod relative to the clamp rod 21, it moves relative to the mounting structure, that is, when it moves relative to the clamp rod 21, the cutting blade 221 set on the distal end of the knife rod can also be pushed forward, and then enter the knife groove of the clamp head, and be pushed along the knife groove, thereby cutting the tissue clamped by the two clamp heads.

[0032] When the electrosurgical instrument needs to be cleaned after use, or the cutting blade 221 needs to be replaced, the mounting structure and the mounting portion 213 can be disassembled and matched first, and then the knife rod can be pulled out of the clamp rod 21. After that, the entire cutting mechanism 22 can be directly replaced, or the cutting blade 221 can be removed and replaced with a new cutting blade 221, or the entire cutting mechanism 22 can be cleaned, sterilized, and disinfected.

[0033] Therefore, in the integrated rod clamp structure of this embodiment, when the cutting mechanism 22 is installed, after its distal end is inserted into the interior of the clamp rod 21 through the mounting hole, the mounting structure cooperates with the mounting portion 213 to connect the cutting mechanism 22 to the clamp rod 21. The installation process is relatively convenient, and the proximal end of the knife rod 222 is exposed from the proximal end of the clamp rod 21. The proximal end of the knife rod 222 can be pushed relative to the clamp rod 21 to drive the cutting blade 221 to be pushed along the knife groove, so that the cutting blade 221 of the rod assembly 2 after assembly is completed can be pushed stably and accurately to ensure a stable and reliable cutting effect; when the cutting mechanism 22 is disassembled, the mounting structure is disengaged from the mounting portion 213, and the knife rod 222 can be pulled out from the distal end of the clamp rod 21, so that its cutting blade 221 can be quickly and rapidly removed, thereby cleaning, disinfecting, and sterilizing the rod assembly 2, or replacing the cutting blade 221, thereby improving the reliability and safety of the reuse of high-frequency surgical instruments.

[0034] The shell assembly 11 may include a bracket, and a knife rod driving mechanism and a clamp rod 21 driving mechanism arranged on the bracket. The portion of the rod assembly 22 located in the shell assembly 11 may be at least partially inserted in the bracket. The knife rod driving mechanism is connected to the proximal end of the knife rod 222 of the integrated rod clamp structure through transmission, and the clamp rod 21 driving mechanism is connected to the proximal end of the clamp rod 21 of the integrated rod clamp structure through transmission.

[0035] As a specific example, see Figure 5 The clamp rod 21 may include a clamp rod guide shaft 211, which may be provided with a toggle slot 212 for engaging with the clamp rod drive mechanism. The outer rod 23 may include an outer rod base 231, which may be provided with a positioning slot 232 for engaging with the housing assembly 1 to connect the outer rod 23 to the housing assembly 1. In addition, to prevent short circuits between metal parts within the integrated clamp structure, a first insulating layer 24 may be provided between the clamp rod 21 and the outer rod 23, and a second insulating layer 25 may be provided on the outer side of the outer rod 23.

[0036] As a specific example, see Figure 4The mounting structure at the proximal end of the knife rod 222 includes a knife rod knob 223, and the knife rod knob 223 includes a knife rod base 226. One end of the knife rod base 226 can be provided with a mounting protrusion, and the other end of the knife rod base 226 is provided with an operating part. The mounting protrusion is used to cooperate with the mounting part 213, so as to install the knife rod knob 223 on the clamp rod 21. The operating part is a plurality of ridges arranged around the outer peripheral surface of the knife rod 222. The operating part is used to apply force during installation to improve the editability of the installation; the knife rod base 226 can be a hollow structure, and the knife rod 222 can be slidably inserted in the knife rod base 226, so that the knife rod 222 can slide relative to the knife rod knob 223.

[0037] As a further optimization, refer to Figure 4 and Figure 5 The proximal end of the knife bar 222 may be provided with a knife bar drive unit 225, which is used to cooperate with the blade pushing mechanism of the bipolar electrocoagulation forceps. The knife bar 222 is provided with a knife bar reset member 224. One end of the knife bar reset member 224 cooperates with the knife bar knob 223, and the other end cooperates with the knife bar drive unit 225. The knife bar reset member 224 is used to reset the knife bar 222. When the cutting operation is not in progress, the proximal end of the knife bar 222 is supported by the knife bar reset member 224, thereby preventing the cutting blade 221 from being pushed along the knife groove at the wrong time. When cutting is in progress, the proximal end of the knife bar 222 moves and forces the knife bar reset member 224 to be compressed. After cutting is completed, the knife bar reset member 224 recovers its deformation and drives the proximal end of the knife bar 222 to reset.

[0038] In addition, the knife rod driving part 225 is provided with a driving surface 227 on the side away from the knife rod knob 223, and a positioning groove or a positioning protrusion is provided on the driving surface 227. The positioning groove and the positioning protrusion are used to cooperate with the slider of the control component 4. The slider can slide relative to the bracket of the control component 4, thereby driving the knife rod 222 to slide.

[0039] The outer diameter of the end of the knife rod driving part 225 close to the knife rod knob 223 is larger than the outer diameter of the knife rod 222, and the outer diameter of the end of the knife rod knob 223 close to the knife rod driving part 225 is larger than the outer diameter of the knife rod 222. The knife rod reset part 224 is a compression spring, one end of the compression spring cooperates with the end of the knife rod driving part 225 close to the knife rod knob 223, and the other end of the compression spring cooperates with the end of the knife rod knob 223 close to the knife rod driving part 225.

[0040] As a further optimization, refer to Figure 6, and also includes a blade guide 35, which is connected to the distal end of the clamp rod 21, one end of the blade guide 35 is in transmission cooperation with at least one of the two clamp heads, and the other end of the blade guide 35 is provided with a guide groove 352 for guiding the blade into the knife groove. When the rod assembly 2 is installed, the front end of the cutting blade 221 can be guided by the guide groove 352 and slide into the knife groove, thereby preventing the front end of the cutting blade 221 from interfering with the blade guide 35 and damaging the cutting blade 221.

[0041] As a specific example of the blade guide 35, refer to Figure 7 The blade guide 35 can be provided with a blade through groove 356 along its axial direction, and the guide groove 352 can be connected to the blade through groove 356, and the size of the guide groove 352 increases gradually from the connection point between the guide groove 352 and the blade through groove 356 to the outside, and forms at least one guide bevel, which is used to guide the front end of the cutting blade 221 into the blade groove.

[0042] As a more specific example, the blade guide 35 may include a mounting end 351 and a driving end 355 , wherein the mounting end 351 is used to connect with the pliers rod 21 , and the driving end 355 is used to be drivingly connected with at least one of the two pliers heads.

[0043] Reference Figure 6 As an example, the two pliers include a first pliers 31 and a second pliers 32. The first pliers 31 is fixedly connected to the distal end of the outer rod 23, and the second pliers 32 is rotatably connected to the first pliers 31 through a connecting pin 33, and a driving slot 321 is provided on the second pliers 32; a driving pin 34 is provided on the blade guide 35, and the driving pin 34 is inserted into the driving slot 321 and cooperates with the driving slot 321 for transmission.

[0044] As a further optimization solution, the second pliers 32 includes at least one connecting ear, a driving groove 321 is opened on the connecting ear, and a receiving groove for accommodating at least part of the connecting ear is opened on the blade guide 35, and the driving pin 34 is located in the receiving groove. When the knife rod 222 moves, the driving pin 34 on the blade guide 35 slides in the driving groove 321, thereby causing the second pliers 32 to rotate.

[0045] When the second pliers head 32 has two connecting ears, the blade guide 35 may have a first receiving groove 353 and a second receiving groove 357. The two connecting ears are respectively inserted into the first receiving groove 354 and the second receiving groove 357. The first receiving groove 354 is provided with a first mounting hole 353, and the second receiving groove 357 is provided with a second mounting hole 358. In order to avoid the cutting blade, two driving pins may be provided, one driving pin connected to the first mounting hole and mating with one of the two connecting ears, and the other driving pin connected to the second mounting hole and mating with the other of the two connecting ears.

[0046] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the inventive purpose of the present invention, designs a structure and embodiment similar to the technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
