Description

Technical Field

[0001] This utility model belongs to the field of surgical electrode technology, specifically relating to a closing and locking structure suitable for surgical electrode handles. Background Technology

[0002] Surgical electrodes are important medical devices. Typically made of conductive materials, they can be placed on or inside the patient's body to measure and record various bioelectrical signals, such as electrocardiograms (ECGs), electroencephalograms (EEGs), and electromyograms (EMGs). They can also be used in electrosurgical procedures, such as electrocautery and electrocoagulation, using high-frequency current to generate heat to cut tissue or coagulate blood vessels. A surgical electrode typically includes an electrode working end, an insulating sheath, a handle, a scalpel shaft, and a forceps head.

[0003] The existing surgical electrode handles require the user to use their fingers to operate a lever to lock and position the forceps head, which does not free the user's hands. In addition, long-term use will not only cause hand discomfort, but also greatly reduce the practicality of the device. Summary of the Invention

[0004] This invention provides a closing and locking structure for surgical electrode handles. The purpose is to solve the problem that existing surgical electrode handles require users to use their fingers to operate an opening and closing wrench to lock and position the forceps head, which does not free the user's hands and causes hand discomfort with long-term use, greatly reducing the practicality of the device.

[0005] This utility model provides a closing and locking structure suitable for a surgical electrode handle, including a handle housing. A mounting base is provided at the right end inside the handle housing. A middle tube is mounted on the mounting base. An outer sleeve and a second outer sleeve are fitted around the outer side of the middle tube. An opening / closing wrench is rotatably mounted inside the handle housing, and the wrench is positioned outside the first outer sleeve. The opening / closing wrench can push the first outer sleeve to move. An inner tube is slidably mounted inside the middle tube. A sliding plate is fixedly connected to the tail of the inner tube. The sliding plate is slidably mounted in upper and lower tracks on the middle tube. The two ends of the sliding plate are connected to the outer sleeve two. A connecting plate is sleeved on the outer side of the outer sleeve two. The sliding groove on the side wall of the connecting plate is slidably connected to the protrusion on the side wall of the wrench. A movable column is provided on the upper side wall of the outer sleeve two. Inclined grooves are reserved on both sides of the connecting plate. The movable column is movably installed in the inclined grooves. A connecting sleeve is provided at the head of the handle housing. An outer tube is provided on the side wall of the connecting sleeve and sleeved outside the middle tube. A rotating sleeve is provided at one end of the connecting sleeve. A locking and positioning component is provided on the handle housing and on the right side of the wrench.

[0006] By adopting the above technical solution, when working, the user holds the handle housing with their fingers on the wrench and moves it. The wrench pushes the connecting plate and the outer sleeve one to move, the connecting plate pushes the outer sleeve two to move, the moving column moves in the inclined groove, the outer sleeve two pushes the slide forward, and then the slide pushes the inner tube forward. The inner tube drives the pliers two to close with the pliers one to achieve clamping. After clamping, the wrench is locked and positioned by the locking and positioning component, ensuring that the user's hands are freed. It is very practical and convenient, greatly improving the ease of use.

[0007] Furthermore, a button is provided at the lower end of the handle housing near the opening / closing wrench.

[0008] By adopting the above technical solution, the power supply to and power off of the surgical electrodes can be controlled by a button.

[0009] Furthermore, rubber sleeves are provided at the lower end of the handle housing and on the opening / closing lever.

[0010] By adopting the above technical solutions, it is ensured that users can grip the handle firmly, preventing the handle from falling and causing discomfort due to sweaty hands, and also improving the comfort of holding the handle.

[0011] Furthermore, a return spring is also sleeved on the outer side of the middle tube, and the two ends of the return spring are respectively connected to the mounting base and the outer tube.

[0012] By adopting the above technical solution, when the opening and closing wrench is turned, the opening and closing wrench drives the outer sleeve to move, and the outer sleeve stretches the return spring. When the opening and closing wrench is released and its locking position is released, the return spring can reset the opening and closing wrench under its deformation force so that it can be used next time.

[0013] Furthermore, a second return spring is also sleeved on the outer side of the middle tube, and the two ends of the second return spring are respectively connected to the side wall of the connecting sleeve and the side wall of one end of the outer sleeve.

[0014] By adopting the above technical solution, when the outer tube 2 moves forward, it compresses the return spring 2. After the force pushing the outer tube 2 disappears, the deformation force of the return spring 2 causes the outer tube 2 to drive the slider, inner tube and connecting plate to return to their original positions for the next use.

[0015] Furthermore, the locking and positioning assembly includes a positioning rod rotatably connected inside the handle housing, a fixing block disposed on the side of the slot at the lower end of the handle housing, and positioning teeth disposed on the side wall of the opening and closing wrench. A plurality of positioning holes are evenly provided on the upper wall surface of the positioning rod. The positioning holes are located on the movement trajectory of the positioning teeth, and the positioning teeth can engage in the positioning holes. A positioning spring is fixedly connected between the end of the positioning rod near the positioning teeth and the fixing block.

[0016] By adopting the above technical solution, when the wrench is turned, the wrench drives the positioning teeth to move along the positioning port. At this time, the positioning spring is compressed. When the wrench moves to the required position, the positioning teeth are locked in the corresponding positioning port, and the positioning spring presses against the positioning rod, so that the positioning teeth are tightly locked in the positioning port, thereby locking the wrench in place. At this time, the user's hand can be released, making it very convenient to use.

[0017] Furthermore, the locking and positioning assembly also includes a rotating shaft disposed at the bottom of the groove at the lower end of the handle housing. A first linkage rod is rotatably connected to the rotating shaft. One end of the first linkage rod extends out of the handle housing, and the other end of the first linkage rod is rotatably connected to a second linkage rod. The other end of the second linkage rod is rotatably connected to the lower wall surface of the positioning rod.

[0018] By adopting the above technical solution, after use, it is necessary to release the locking position of the wrench. Push the first linkage rod upward, the first linkage rod pulls the second linkage rod downward, the second linkage rod pulls the positioning rod downward, the positioning rod rotates and causes the positioning port to move away from the positioning teeth. The positioning teeth quickly return to their original position with the wrench, thereby canceling the locking position of the wrench, which is very convenient to use.

[0019] The beneficial effects of this utility model are as follows:

[0020] When this utility model is in operation, the user holds the handle housing and places their fingers on the opening and closing wrench. Moving the wrench causes the connecting plate and outer sleeve one to move, which in turn causes the connecting plate to move the outer sleeve two. The moving column moves in the inclined groove, and the outer sleeve two pushes the sliding plate forward, which in turn pushes the inner tube forward. The inner tube then causes the pliers two to close with the pliers one, achieving clamping. After clamping, the locking and positioning assembly locks and positions the opening and closing wrench, ensuring that the user's hands are free. This practical and convenient design greatly improves ease of use.

[0028] Reference Figure 1-3 This utility model embodiment proposes a closing and locking structure suitable for surgical electrode handles, including a handle housing 1. A mounting base 2 is provided at the right end inside the handle housing 1. A middle tube 3 is mounted on the mounting base 2. An outer sleeve 4 and an outer sleeve 7 are fitted around the outer side of the middle tube 3. An opening / closing lever 6 is rotatably mounted inside the handle housing 1, fitted around the outer sleeve 4, and the lever 6 can push the outer sleeve 4 to move. An inner tube 8 is slidably mounted inside the middle tube 3. A slider 9 is fixedly connected to the tail of the inner tube 8. The slider 9 is slidably mounted in two upper and lower tracks on the middle tube 3. Both ends of the slider 9 are connected to the outer sleeve 7. An outer sleeve 7 is fitted around the outer side of the outer sleeve 7. The connecting plate 10 has a sliding groove on its side wall that is slidably connected to the protrusion on the side wall of the opening and closing wrench 6. A movable column 11 is provided on the side wall of the upper end of the outer tube 7. Inclined grooves 12 are reserved on both sides of the connecting plate 10. The movable column 11 is movably installed in the inclined grooves 12. A connecting sleeve 13 is provided at the head of the handle housing 1. An outer tube is provided on the side wall of the connecting sleeve 13 that is sleeved on the outside of the middle tube 3. A rotating sleeve 14 is provided at one end of the connecting sleeve 13. A locking and positioning component 16 is provided on the handle housing 1 and on the right side of the opening and closing wrench 6. The head end of the outer tube is fixedly connected to the first pliers head. The head end of the inner tube 8 is rotatably connected to the second pliers head. The first pliers head and the second pliers head are connected by a pin.

[0029] When in operation, the user holds the handle housing 1 with their fingers inside the opening and closing wrench 6 and moves the wrench 6. The opening and closing wrench 6 pushes the connecting plate 10 and the outer sleeve 4 to move. The connecting plate 10 pushes the outer sleeve 7 to move, and the moving column 11 moves in the inclined groove 12. The outer sleeve 7 pushes the slider 9 forward, which in turn pushes the inner tube 8 forward. The inner tube 8 drives the pliers head 2 to close with the pliers head 1 to achieve clamping. After clamping, the opening and closing wrench 6 is locked and positioned by the locking and positioning component 16, ensuring that the user's hands are free. It is very practical and convenient, greatly improving the ease of use.

[0030] Reference Figure 1 A button 17 is provided on the lower end of the handle housing 1 near the opening and closing wrench 6.

[0031] The power supply to and from the surgical electrodes can be controlled via button 17.

[0032] Reference Figure 1 and Figure 2 Both the lower end of the handle housing 1 and the opening / closing wrench 6 are equipped with rubber sleeves.

[0033] It ensures that users can grip the handle firmly, preventing the handle from falling and causing discomfort due to sweaty hands, and also improves the comfort of holding it.

[0034] Reference Figure 2 A return spring 5 is also sleeved on the outside of the middle tube 3. The two ends of the return spring 5 are connected to the mounting base 2 and the outer tube 4, respectively.

[0035] When the opening and closing wrench 6 is moved, the opening and closing wrench 6 drives the outer tube 4 to move, and the outer tube 4 stretches the return spring 5. When the opening and closing wrench 6 is released and its locking position is released, the return spring 5 can return the opening and closing wrench 6 to its original position under its deformation force so that it can be used next time.

[0036] Reference Figure 2 A second reset spring 15 is also sleeved on the outside of the middle tube 3. The two ends of the second reset spring 15 are respectively connected to the side wall of the connecting sleeve 13 and the side wall of one end of the outer sleeve 7.

[0037] When the outer tube 2 7 moves forward, it compresses the return spring 2 15. After the force pushing the outer tube 2 7 disappears, the deformation force of the return spring 2 15 causes the outer tube 2 7 to drive the slider 9, inner tube 8 and connecting plate 10 to return to their original positions for the next use.

[0038] Reference Figure 2The locking and positioning assembly 16 includes a positioning rod 164 rotatably connected inside the handle housing 1, a fixing block 167 disposed on the side of the slot at the lower end of the handle housing 1, and positioning teeth 166 disposed on the side wall of the opening and closing wrench 6. A plurality of positioning holes 165 are evenly provided on the upper wall surface of the positioning rod 164. The positioning holes 165 are located on the movement trajectory of the positioning teeth 166, and the positioning teeth 166 can engage in the positioning holes 165. A positioning spring 168 is fixedly connected between the end of the positioning rod 164 near the positioning teeth 166 and the fixing block 167.

[0039] When the opening and closing wrench 6 is turned, the opening and closing wrench 6 drives the positioning tooth 166 to move along the positioning port 165. At this time, the positioning spring 168 is compressed. When the opening and closing wrench 6 moves to the desired position, the positioning tooth 166 is locked in the corresponding positioning port 165, and the positioning spring 168 presses against the positioning rod 164, so that the positioning tooth 166 is tightly engaged in the positioning port 165, thereby locking the opening and closing wrench 6 in place. At this time, the user's hand can be released, making it very convenient to use.

[0040] Reference Figure 2 The locking and positioning assembly 16 also includes a rotating shaft 161 disposed at the bottom of the groove at the lower end of the handle housing 1. A first linkage rod 162 is rotatably connected to the rotating shaft 161.

The other end of the second linkage rod 163 is rotatably connected to the lower wall surface of the positioning rod 164.

[0041] After use, the locking position of the opening and closing wrench 6 needs to be released. Push the linkage rod 162 upward, and the linkage rod 162 pulls the linkage rod 163 downward. The linkage rod 163 pulls the positioning rod 164 downward. The positioning rod 164 rotates and causes the positioning port 165 to move away from the positioning tooth 166. The positioning tooth 166 quickly returns to its original position with the opening and closing wrench 6, thereby releasing the locking position of the opening and closing wrench 6. It is very convenient to use.
