Description

Technical Field

[0001] This utility model relates to a rotatable connection structure, specifically to a rotating structure at the tail of an electric knife pen. Background Technology

[0002] Surgical electrosurgical pen is a high-frequency electrosurgical device that destroys diseased tissue using electric current. It does not simply involve heating the electrode or blade. Instead, it concentrates a high-current density high-frequency current to directly destroy the tissue at the point of contact with the effective electrode tip. When the temperature of the tissue or cells in contact with or near the effective electrode rises to the point where the proteins in the cells denature, coagulation occurs. This precise surgical effect is determined by the waveform, voltage, current, tissue type, and the shape and size of the electrode.

[0003] Conventional electrosurgical scalpels typically come with a flexible tube and a power cord. For example, Chinese patent document CN209186934U discloses a smoking electrosurgical scalpel with a flexible tube and power cord at the end, but without a rotatable end structure. This design makes it difficult for medical staff to operate the scalpel, as they may be dragged by the tube or power cord. It also increases the risk of the cord getting tangled and poses no safety risk to medical staff. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the background art and provide a rotating tail structure for an electrosurgical pen. The rotating tail structure of the electrosurgical pen has good rotation performance and operability, which improves the safety and reliability of the surgical electrosurgical pen during use, reduces the restrictions on medical staff by the electrosurgical pen hose and wire during use, and improves the comfort of the surgical electrosurgical pen during use.

[0005] The purpose of this utility model is mainly achieved through the following solutions:

[0006] A rotating tail structure for an electrosurgical pen includes a connecting tube, a cable harness, and an electrosurgical pen tail tube. The connecting tube is equipped with a locking mechanism, and its inner surface has an inner ring groove and an inner arc groove. The front end of the outer surface of the cable harness has a ball head, and a rotation limiting boss is provided behind the ball head. The rear end of the electrosurgical pen tail tube has a buckle, and its interior has a flexible tube cavity and a pen tube cavity. The cable harness is connected to the inner arc groove of the connecting tube through the ball head, and the electrosurgical pen tail tube is connected to the inner ring groove of the connecting tube through the buckle. The head of the connecting tube faces the electrosurgical pen tail tube, and the tail of the connecting tube faces the cable harness. The connecting tube, the cable harness, and the electrosurgical pen tail tube are all hollow structures, and their interiors are interconnected.

[0007] The connecting tube, the wire harness tube, and the electrosurgical pen tail tube together constitute the main body of the rotating structure at the tail of the electrosurgical pen. The inner ring groove of the connecting tube is connected to the groove of the electrosurgical pen tail tube with a clearance fit, realizing the circumferential rotation of the electrosurgical pen tail tube within the connecting tube. The inner arc groove of the connecting tube is connected to the ball head of the wire harness tube through a universal joint structure. The rotation limiting boss behind the ball head can ensure that the wire harness tube rotates within the connecting tube. This rotating structure at the tail of the electrosurgical pen increases the flexibility and operability of the electrosurgical pen during use, avoids the connection part from being penetrated or contaminated during surgery, and also prevents medical staff from directly contacting the wire with their arms or body when operating the electrosurgical pen, thus improving the safety of medical staff.

[0008] Preferably, the buckle is engaged with the inner ring groove with a clearance fit, allowing the electric knife pen tail tube to rotate circumferentially within the connecting tube.

[0009] Because the connection uses a clearance fit, the electric drill can rotate circumferentially inside the connecting housing, increasing the flexibility and operability of the electric drill during use.

[0010] Preferably, the ball head and the inner arc groove form a universal joint structure, and the rotation limiting boss is provided behind the ball head so that the cable bundle can rotate inside the connecting tube.

[0011] The cable harness uses a ball-head structure connected to an arc-groove universal joint structure and is equipped with a rotation limiting boss, which allows the cable harness to rotate inside the connecting tube. This reduces the restriction on medical staff by the flexible tube or wire of the electrosurgical pen during operation, increases the safety of medical staff, and also improves the comfort of medical staff when using the electrosurgical pen.

[0012] Preferably, the electric knife pen tail tube has a flexible tube cavity and a pen tube cavity inside, and the flexible tube cavity and the pen tube cavity are connected by a connecting cavity.

[0013] During daily use, the flexible tube or wire at the end of an electrosurgical pen is often dragged, bent, or tangled. This not only reduces the lifespan of the pen but also causes the wire or tube to come into direct contact with medical personnel, increasing safety hazards. The hollow structure allows the flexible tube or wire to pass directly through the rotating structure at the end of the pen, preventing direct contact with the skin of medical personnel and ensuring their safety. It also avoids dragging, bending, and tangling of the flexible tube or wire, thus extending the lifespan of the electrosurgical pen.

[0014] Preferably, the top of the rotating limiting boss is connected to the ball head, and the tail of the rotating limiting boss extends beyond the tail of the connecting pipe.

[0015] The tail of the rotating limiting boss extends beyond the tail of the connecting tube. When the ball head rotates to a certain angle, the tail of the rotating limiting boss will press against the tail of the connecting tube, and the ball head will no longer be able to rotate. In this way, the flexible tube or wire passing through the cable bundle will not bend or break due to excessive rotation of the ball head, ensuring the safety of the flexible tube and wire and increasing the service life of the electrosurgical pen. It also eliminates the restriction of the flexible tube or wire on medical staff, increases the safety of medical staff, and improves the comfort of medical staff during use.

[0016] Preferably, the cable bundle includes a straight cable bundle and a bent cable bundle.

[0017] The angle at which the straight and curved wire tubes are connected perfectly matches the angle of the wrist flexion during use, preventing the wrist from affecting the accuracy of the surgery during prolonged operation of the electrosurgical pen and improving the comfort of operation.

[0018] Preferably, the cable bend is provided with a sleeve limiting boss and a sleeve anti-slip boss.

[0019] The tail end of the cable tie is fitted with a sleeve. The flexible tube and wire of the electric scalpel are wrapped in the sleeve after passing through the cable tie, which avoids friction and scratches on the flexible tube or wire during use and increases the service life of the electric scalpel. At the same time, the sleeve limiting boss and the sleeve anti-slip boss at the tail end of the cable tie ensure that the sleeve will not move forward or backward after being installed on the cable tie, increasing the reliability during use.

[0020] Preferably, the connecting pipe is provided with a locking mechanism, which includes a first locking mechanism and a second locking mechanism.

[0021] Preferably, both the first locking mechanism and the second locking mechanism include a locking knob, a locking spring, and a locking rod.

[0022] Preferably, the locking knob is provided with a locking top head at the part where it connects with the locking rod, and a locking top plate is provided on the locking top head.

[0023] Preferably, the portion where the locking rod connects to the locking knob is provided with a locking recess, and the locking recess is provided with a locking positioning groove and a sliding inclined rail.

[0024] Preferably, the buckle of the electric knife pen tail tube is provided with a first locking groove, and the ball head of the wire harness tube is provided with a second locking groove.

[0025] During use, situations may arise where the tail tube of the electrosurgical pen or the cable harness needs to be fixed. This mechanism is equipped with a first locking mechanism and a second locking mechanism. When the tail tube of the electrosurgical pen needs to be locked, the first locking mechanism can be used. By rotating the locking knob of the first locking mechanism, the locking top plate on the locking top head will push the locking rod of the first locking mechanism towards the first locking groove through the sliding inclined rail of the locking recess. When the locking top plate rotates away from the sliding inclined rail and reaches the locking positioning groove, the rotation stops, and the locking rod of the first locking mechanism will be pushed into the first locking groove, locking the rotation of the tail tube of the electrosurgical pen. Rotating the locking knob of the first locking mechanism again will disengage the locking top plate from the locking positioning groove, and the locking rod of the first locking mechanism will return to its original position under the elastic force of the locking spring. The locking top head will enter the locking recess, the first locking mechanism will open, and the tail tube of the electrosurgical pen can continue to move freely. Rotation; when the cable bundle needs to be locked, the second locking mechanism can be used. Rotating the locking knob of the second locking mechanism causes the locking top plate on the locking top to push the locking rod of the second locking mechanism towards the second locking groove via the sliding rail of the locking recess. When the locking top plate rotates away from the sliding rail and reaches the locking positioning groove, the rotation stops, and the locking rod of the second locking mechanism is pushed into the second locking groove, locking the rotation of the cable bundle. Rotating the locking knob of the second locking mechanism again causes the locking top plate to disengage from the locking positioning groove, and the locking rod of the second locking mechanism returns to its original position under the elastic force of the locking spring. The locking top then enters the locking recess, opening the second locking mechanism, allowing the cable bundle to continue rotating freely. The first and second locking mechanisms operate independently, meeting the needs of different working conditions and increasing the practicality and operability of this rotating structure.

[0026] In summary, this utility model has the following beneficial effects:

[0027] 1. The rotating structure at the tail of the electrosurgical pen adopts a clearance fit, which can realize the circumferential rotation of the connection part, greatly increasing the flexibility and operability of the electrosurgical pen during use. It also avoids the tubing and wire at the tail of the electrosurgical pen from being dragged, bent, or tangled, thus improving the service life of the electrosurgical pen. At the same time, it also eliminates the direct contact between the wire of the electrosurgical pen and the skin of medical staff, ensuring the personal safety of medical staff.

[0028] 2. The cable bundle adopts a ball head structure and a circular arc groove universal joint structure for connection and is equipped with a rotation limiting boss, which allows the cable bundle to rotate in the connecting tube. This reduces the restriction on medical staff by the flexible tube or wire of the electrosurgical pen during operation, increases the safety of medical staff, and also improves the comfort of medical staff when using the electrosurgical pen.

[0029] 3. The angles of the straight and curved wire bundles perfectly conform to human aesthetics, avoiding the impact of the wire bundles on the wrist during prolonged use by medical staff and improving the accuracy during use.

[0030] 4. The connecting tube, the wire harness tube, and the tail tube of the electric drill are all hollow structures. The flexible tube and wire of the electric drill can pass through the hollow structure and directly enter the inside of the sleeve, avoiding the wetting or contamination caused by direct contact between the flexible tube or wire and the environment, thus increasing the reliability of use.

[0031] 5. The locking structure can adapt to special usage situations where the electric scalpel tail tube or cable bundle tube does not need to rotate. In this way, the electric scalpel tail tube or cable bundle tube can be easily locked and rotated by two sets of locking mechanisms. Moreover, the two sets of locking mechanisms are independent and do not interfere with each other, which increases the practicality and operability of this electric scalpel tail rotation structure.

Detailed Implementation

[0038] The following specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to this utility model without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.

[0039] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0040] Example 1: As Figures 1-3 As shown, a rotating structure for the tail of an electric scalpel includes a connecting tube 1, a wire harness tube 2, and an electric scalpel tail tube 3. The inner surface of the connecting tube 1 has an inner ring groove 11 and an inner arc groove 12. The front end of the outer surface of the wire harness tube 2 is provided with a ball head 21, and a rotation limiting boss 22 is provided behind the ball head 21. The wire harness tube is composed of a straight wire harness tube 26 and a bent wire harness tube 25. The bent wire harness tube is provided with a sleeve limiting boss 23 and a sleeve anti-slip boss 24. The rear end of the electric scalpel tail tube 3 is provided with a buckle 31. The electric scalpel tail tube 3 has a flexible tube cavity 33 and a pen tube cavity 34 inside, which are connected through a connecting cavity 32. The head of the connecting tube 1 faces the electric scalpel tail tube 3, and the tail of the connecting tube 1 faces the wire harness tube 2. The connecting tube 1, the wire harness tube 2, and the electric scalpel tail tube 3 are all hollow structures, and the interiors of the connecting tube 1, the wire harness tube 2, and the electric scalpel tail tube 3 are interconnected.

[0041] The ball head 21 and the inner arc groove 12 form a universal joint structure. The rotation limiting boss 22 behind the ball head 21 allows the cable bundle 2 to rotate inside the connecting tube 1. The electric knife pen tail tube 3 is connected to the inner ring groove 11 of the connecting tube 1 through the buckle 31 with a gap fit, allowing the electric knife pen tail tube 3 to rotate circumferentially inside the connecting tube 1.

[0042] The connecting tube 1, the cable bundle 2, and the electrosurgical pen tail tube 3 are all hollow structures and internally connected. The flexible tube of the electrosurgical pen can pass through the flexible tube cavity 33 of the tail tube 3, and the wire of the electrosurgical pen can pass through the pen tube cavity 34 of the tail tube. The flexible tube and tail tube of the electrosurgical pen finally converge through the connecting cavity 32 of the tail tube 3, avoiding the frequent tangling and knotting of the flexible tube and wire during use, thus increasing the service life of the electrosurgical pen. The rotating structure at the tail of the electrosurgical pen provides better flexibility and operability when the tail flexible tube or wire needs to be raised during surgery. It reduces the restriction on medical staff by the flexible tube and wire during operation, avoids direct contact between the wire and the skin, increases safety, and improves user comfort. The connection angle of the straight cable bundle 26 and the curved cable bundle 25 of the cable bundle 2 perfectly conforms to human aesthetics, ensuring that medical staff do not feel uncomfortable during long surgical procedures and improving surgical precision.

[0043] Example 2: As Figure 4 and Figure 5 As shown, unlike Embodiment 1, the buckle 31 of the electric drill tail tube 3 is provided with a first locking groove 35, and the ball head 21 of the cable tie tube 2 is provided with a second locking groove 27; the connecting tube 1 is provided with a locking mechanism 4, which includes a first locking mechanism 41 and a second locking mechanism 42; both the first locking mechanism 41 and the second locking mechanism 42 include a locking knob 401, a locking spring 402 and a locking rod 403; a locking top head 4011 is provided at the part where the locking knob 401 and the locking rod 403 are connected, and a locking top plate 4012 is provided on the locking top head 4011; a locking recess head 4031 is provided at the part where the locking rod 403 and the locking knob 401 are connected, and a locking positioning groove 4032 and a sliding rail 4033 are provided on the locking recess head 4031.

[0044] The first locking mechanism 41 can lock the rotation of the electric knife pen tail tube 3. Rotating the locking knob 401 of the first locking mechanism 41 causes the locking top plate 4012 on the locking top head 4011 to push the locking rod 403 of the first locking mechanism 41 towards the first locking groove 35 via the sliding inclined rail 4033 of the locking recess 4031. When the locking top plate 4012 rotates away from the sliding inclined rail 4033 and reaches the locking positioning groove 4032, the rotation stops, and the locking mechanism 41 is engaged. The rod 403 will be pushed into the first locking groove 35, and the rotation of the electric knife pen tail tube 3 will be locked; rotate the locking knob 401 of the first locking mechanism 41 again, the locking top plate 4012 will disengage from the locking positioning groove 4032, the locking rod 403 of the first locking mechanism (41) will return to its original position under the elastic force of the locking spring 402, the locking top 4011 will enter the locking recess 4031, the first locking mechanism 41 will open, and the electric knife pen tail tube 3 can continue to rotate freely.

[0045] The second locking mechanism 42 can lock the rotation of the cable tie tube 2. By rotating the locking knob 401 of the second locking mechanism 42, the locking top plate 4012 on the locking top head 4011 will push the locking rod 403 of the second locking mechanism 42 towards the second locking groove 27 through the sliding inclined rail 4033 of the locking recess 4031. When the locking top plate 4012 rotates away from the sliding inclined rail 4033 and reaches the locking positioning groove 4032, the rotation stops, and the second locking mechanism 42... The locking rod 403 will be pushed into the second locking groove 27, and the rotation of the cable tie tube 2 will be locked. When the locking knob 401 of the second locking mechanism 42 is rotated again, the locking top plate 4012 will disengage from the locking positioning groove 4032, the locking rod 403 of the second locking mechanism 42 will return to its original position under the elastic force of the locking spring 402, the locking top 4011 will enter the locking recess 4031, the second locking mechanism 42 will open, and the cable tie tube 2 can continue to rotate freely.

[0046] The first locking mechanism 41 and the second locking mechanism 42 are two independent working mechanisms that can perfectly adapt to situations where the tail tube of the electrosurgical pen or the cable bundle needs to be locked during use. During precise surgeries, the rotation of the electrosurgical pen may affect the accuracy of the procedure. In this case, medical staff can operate the first locking mechanism 41 to lock the rotation of the tail tube 3 of the electrosurgical pen, thus preventing rotation during use and improving surgical precision. During the use of the electrosurgical pen, if medical staff need to raise or lower the flexible tube and wire at the tail of the electrosurgical pen for fixation, they can operate the second locking mechanism 42 to rotate and lock the cable bundle 2. This fixes the flexible tube or wire at the tail of the electrosurgical pen without affecting the operation and improves user comfort.
