DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figure 1-2 As shown, a rod clamp quick-release mechanism of the present invention includes a rod assembly 2, an actuator assembly 1 and a knob 3.

[0026] Among them, the actuator assembly 1 can be arranged at the end of the rod assembly 2, specifically the distal end of the rod assembly 2. The actuator assembly 1 includes a clamp 11 for contacting tissue. The clamp 11 usually includes two clamp heads. The two clamp heads can be close to each other to clamp the tissue. After the tissue is clamped, the conductive plate located on the clamp head is connected to the high-frequency energy platform, thereby transmitting high-frequency electrical energy between the clamped tissue to achieve sealing of the clamped tissue and achieve hemostasis; after the sealing is completed, the blade can be driven to advance along the knife groove on the clamp head, thereby cutting the sealed tissue.

[0027] The knob 3 is mounted on the other end of the rod assembly 2 away from the actuator assembly 1, that is, the rod assembly 2 is closer to the proximal end of the main body of the bipolar coagulation forceps. After the rod assembly 2 is rotatably connected to the main body of the bipolar coagulation forceps, the knob 3 is used to drive the rod assembly 2 to rotate relative to the main body of the bipolar coagulation forceps to adjust the angle of the clamp 11.

[0028] A quick-release assembly 4 may be connected to the knob 3 , and the quick-release assembly 4 is used to quickly assemble and disassemble the rod assembly 2 and the main body of the bipolar electrocoagulation forceps.

[0029] As an example, the quick release assembly 4 includes a trigger member 42 and a locking seat 41, the rod assembly 2 is at least partially inserted into the locking seat 41, and the trigger member 42 can slide relative to the locking seat 41 so that the trigger member 42 has an unlocked state and a locked state. When the trigger member 42 is in a locked state, the rod assembly 2 is locked with the locking seat 41, and the knob 3 can drive the rod assembly 2 to rotate. Since the knob 3 is usually rotatably connected to the main body of the bipolar coagulation forceps, the rod assembly 2 and the actuator assembly 1 arranged at the distal end of the rod assembly 2 are rotatably connected to the main body of the bipolar coagulation forceps; when the trigger member 42 is in an unlocked state, the rod assembly 2 and the locking seat 41 are released from the locking seat 41, and the rod assembly 2 can be removed from the locking seat 41, while the knob 3 is still connected to the main body of the bipolar coagulation forceps, that is, the rod assembly 2 and the actuator assembly 1 arranged at the distal end of the rod assembly 2 are removed from the main body of the bipolar coagulation forceps, thereby completing the rapid removal of the rod assembly 2 from the main body of the bipolar coagulation forceps.

[0030] By adopting the above-mentioned technical solution of this embodiment, the user can quickly and easily remove the rod assembly and the actuator assembly 1 from the main body through the quick-release assembly 4 for cleaning, disinfection, sterilization and other operations, ensuring the safety of the instrument during reuse, and reusable instruments also reduce the waste of medical resources and reduce medical costs.

[0031] As an example of a motivating method, Figure 1As shown, a rod clamp quick-release mechanism of the utility model can also include a button 31, which is protruding and embedded on the knob 3, or is a part of the knob 3. The button 313 is in contact with the trigger member 42, and the button 313 can be used to drive the trigger member 42 to slide relative to the locking seat 41. The surface of the knob 3 can be provided with ridges, which increases the friction between the user and the knob 3, further ensures the reliability of the actuator assembly 1 during rotation control by the knob 3, and facilitates the user to position during operation, further improving the convenience of the disassembly process.

[0032] Of course, as another example of the excitation method, an operating hole can be opened on the knob 3 so that at least a portion of the excitation member 42 can be exposed from the knob 3. The user can operate the excitation member 42 by pressing the portion of the excitation member 42 exposed from the knob 3.

[0033] As an example of an excitation element, Figure 3-4 As shown, the trigger member 42 may include a contact portion 421, a fixing portion 423 and an elastic member 422. When a button 31 is provided on the knob 3, the contact portion 421 may be in contact with and cooperate with the button 31. The fixing portion 423 may be locked and cooperated with the rod assembly 2 when the trigger member 42 is in a locked state, and may be disengaged from the rod assembly 2 when the trigger member 42 is in an unlocked state. This locking cooperation may be a friction cooperation to achieve locking, or a shape cooperation to achieve locking, or a locking cooperation similar to a latch and a pin control, or any other cooperation method that can achieve locking to prevent the rod assembly 2 from moving along its axial direction relative to the locking seat 41. The elastic member 422 is arranged on the contact portion 421 to realize the reset of the trigger member 42. The elastic member 422 can be a spring in the form of a compression spring, a tension spring, a torsion spring, etc. One leg of the spring cooperates with the trigger member 42, and the other leg of the spring cooperates with the locking seat 41 or the knob 3. When force is applied to the trigger member 42 to put it in an unlocked state, the elastic member 422 is deformed and has elastic potential energy. When the force is removed, the elastic member 422 restores its deformation and drives the trigger member 42 to reset.

[0034] As an example of a locking seat, Figure 5 As shown, a limiting groove 411 that matches the fixing portion 423 is provided on the side of the locking seat 41, and a first channel 412 for the rod assembly to pass through is provided in the middle of the locking seat 41.

[0035] By adopting the above technical solution, during use, the user can press the button 31 set on the knob 3, and the button 31 presses down to trigger the trigger member 42, so that the trigger member 42 switches from the locked state to the unlocked state. At the same time, the fixing portion 423 disengages from the rod assembly 2, so that the rod assembly can be disengaged from the first channel 412 set in the middle of the locking seat 41, and the rod assembly 2 can be disassembled quickly and easily.

[0036] As one example, as Figure 6 shown, the rod assembly may include a tool rod 21, a clamp rod 22, an outer rod 23, a first insulating layer 25, and a second insulating layer 24 that can be sleeved into an integral structure. The tool rod 21 is arranged in the innermost layer, a cutting blade 211 is provided at the end of the tool rod 21, a clamp 11 is provided at the end of the clamp rod 22, a first insulating layer 25 is provided between the tool rod 21 and the clamp rod 22, the outer rod 23 is arranged in the outermost layer, a second insulating layer 24 is provided between the outer rod 23 and the clamp rod 22. The materials of the first insulating layer 25 and the second insulating layer 24 can be resin, can be silicone rubber, can be PVC, or can be any other material that can achieve the same function.

[0037] In addition, at least one locking hole 231 is provided on the outer rod 23, and multiple locking holes 231 can also be provided. The locking hole 231 is used for locking and cooperating with the fixing part 423.

[0038] As a further optimization, as Figure 4 shown, the fixing part 423 can be a C-shaped structure, or can be any other structure that can achieve the same function, such as a 冂-shaped structure, a V-shaped structure, etc. A fixing protrusion 424 can be provided at the bottom end of the C-shaped structure. At least one locking hole 231 corresponding to the position of the fixing protrusion 424 can be opened on the lower side of the outer rod 23, or multiple fixing protrusions 424 can be provided, and multiple locking holes 231 corresponding to the positions of the multiple fixing protrusions 424 can be opened on the lower side of the outer rod 23. The outer rod 23 is inserted into the C-shaped structure, and the fixing protrusion 424 is locked and cooperated with the locking hole 231. In addition, a limiting groove 411 can be opened on the locking seat 41, and the limiting groove 411 is used for accommodating the C-shaped structure of the fixing part 423. When the rod assembly 2 attempts to move relative to the locking seat 41 along its axial direction in the locked state, the locking hole 231 interferes with the fixing protrusion 424, and the C-shaped structure abuts against the groove wall of the limiting groove 411, preventing the fixing part 423 from breaking and damaging the rod clamp quick-release mechanism of the present utility model.

[0039] By adopting the above technical solution, when the actuating part 42 is in the locked state, the rod assembly can be firmly inserted into the first channel 412 of the locking seat 41 through the cooperation of the fixing part 423 and the locking hole 231, ensuring the structural stability of the instrument.

[0040] The present utility model also provides a bipolar coagulation forceps. The bipolar coagulation forceps of the present utility model includes a rod clamp quick-release mechanism and a main body. The rod clamp quick-release mechanism is the rod clamp quick-release mechanism described above in this embodiment, and the rod assembly 2 of the rod clamp quick-release mechanism is detachably connected to the main body.

[0041] Among them, the main body includes a control component and a shell component, the control component is arranged in the shell component, the knob 3 is mounted on the shell component, the end of the rod component 2 away from the actuator component 1 is at least partially inserted in the control component, and the rod component 2 is coordinated with the control component in transmission, so that the control component can drive the clamp 11 of the rod component 2 to clamp the tissue and drive the blade of the rod component 2 to cut the tissue.

[0042] As an example, the bipolar coagulation forceps of this embodiment may also include a first connecting seat 5, the control component includes a first connecting plate 6 and a second connecting plate 7, and the first connecting seat 5 is provided with a first screw hole and a second screw hole on both sides for bolting the first connecting plate 6 and the second connecting plate 7. The middle of the first connecting seat 5 is provided with a second channel 51 for the rod assembly 2 to pass through. After the rod assembly 2 passes through the second channel 51, it can be connected to the clamp head drive assembly and the knife rod drive assembly of the control assembly through transmission.

[0043] Compared with the prior art, the utility model is provided with a rod clamp quick-release mechanism, so that the rod assembly and the actuator assembly 1 can be simply and quickly disassembled for cleaning and disinfection, ensuring the safety and effectiveness of the bipolar coagulation forceps during use. At the same time, the reusable bipolar coagulation forceps also reduces waste and lowers medical costs.

[0044] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
