Description

Technical Field

[0001] The invention relates to the technical field of radio frequency therapeutic apparatus, and in particular to a bionic continuum radio frequency therapeutic apparatus for arthroscopic surgery. Background Art

[0002] In existing hip arthroscopy, surgical instruments include hip arthroscopy, guide needle, cutter, radiofrequency device, bite forceps, etc. Radiofrequency device is generally composed of handle, power supply and probe. The surgeon activates radiofrequency energy by controlling the button on the handle, which can heat the tissue to a high temperature to cut or coagulate the tissue. The current radiofrequency device is inserted into the patient's hip joint through a guide tube, and the external control device operates in the hip joint. In hip arthroscopy, radiofrequency devices can generally be classified according to function and design. Common ones include monopolar radiofrequency devices, which have basic active electrodes and ground electrodes; bipolar radiofrequency devices, which provide more precise energy delivery; multipolar radiofrequency devices, which can output uniform radiofrequency energy, so that the radiofrequency energy produces better thermal effects in both parallel and vertical directions relative to the active layer. In the field of hip arthroscopy, in addition to those radiofrequency devices used to perform basic functions, there are also a series of radiofrequency devices with additional functions, which are designed to improve the efficiency and accuracy of the operation. One of the innovative designs includes a radiofrequency device with a catheter, which combines catheter technology to enable doctors to more accurately guide the delivery of radiofrequency energy, thereby achieving more delicate treatment of specific tissues. In addition, there is a technology called ablation radiofrequency, which combines the features of ablation and radiofrequency energy delivery and can be used to treat specific types of soft tissue problems, providing medical professionals with more treatment options.

[0003] Given the small space of the hip joint and the complex structure of the ball-and-socket joint, and the fact that the front working area of ​​the current radiofrequency device is mostly in the form of a rigid straight tube without the function of rotation, it is difficult for doctors to accurately place the device at the lesion with the existing device, which poses a great challenge to the operation.

[0038] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] Reference Figure 1-Figure 7 The present invention provides a bionic continuum radiofrequency therapeutic apparatus for arthroscopic surgery, comprising a host 6, a handle 4, a guide wire 5 and a radiofrequency head 1.

[0040] A continuum backbone 2 is disposed at the front end of the handle 4, and a first fixing sleeve 3 is disposed at the front end of the continuum backbone 2;

[0041] The rotating assembly includes a connecting shaft and a rotating member. A hose sleeve 9 is arranged in the continuum backbone 2. The rotating member is arranged at the front end of the hose sleeve 9. The radio frequency head 1 is rotatably connected to the rotating member and is connected to the host 6 through the connecting shaft.

[0042] The limiting assembly includes a first limiting member and a second limiting member. The rotating member is limitedly connected to the first fixed sleeve 3 through the first limiting member. The second limiting member is sleeved on the hose sleeve 9 and connected to the first fixed sleeve 3, and is used to limit the connection between the first limiting member and the first fixed sleeve 3.

[0043] Specifically, the rotation of the radio frequency head 1 is ensured by the provided connecting shaft and rotating parts, and the stable and convenient installation and disassembly of the radio frequency head 1 is realized by the provided limiting assembly, so that the doctor can more accurately control the movement and rotation of the device inside the hip joint, realize precise treatment, and the operation process is more convenient. The doctor can easily adjust the position and angle of the device to improve the treatment effect. The stable connection reduces the risk of accidents and ensures that the device is firmly and reliably fixed during the treatment. The improvement in safety means that patients and doctors are more assured during the treatment process and the risk of potential complications is reduced.

[0044] As an optional embodiment, the rotating member includes:

[0045] A radio frequency fixing sleeve 10, one end of which is fixedly connected to the front end of the hose sleeve 9;

[0048] In one embodiment of the present invention, referring to Figure 4 The RF head 1 is rotatably connected between the RF fixing sleeve 10 and the second fixing sleeve 11 through the second fixing sleeve 11, so as to realize the rotation of the RF head 1, thereby ensuring that the RF head 1 can flexibly rotate inside the hip joint, and can perform surgical operations on the tissue more accurately.

[0049] As an optional implementation, the first limiting member includes:

[0050] The first fixing sleeve 3 is provided with a first slot 22, and the first fixing sleeve 3 is provided with a first slot 22, and the first fixing sleeve 3 is provided with a first slot 22.

[0051] The first bayonet 12 is fixedly connected to the RF fixing sleeve 10 , and the bottom end of the plug pin 7 is fixedly connected to the second bayonet 13 . The RF fixing sleeve 10 is located in the first fixing sleeve 3 and is limitedly connected by the first bayonet 12 and the second bayonet 13 .

[0052] In one embodiment of the present invention, referring to Figure 3 The provided latch pin 7 extends into the first slot 22 , and the RF fixing sleeve 10 moves in the first fixing sleeve 3 . When the RF fixing sleeve 10 moves to the nail placement position, the first latch pin 12 is connected to the second latch pin 13 , thereby fixing the RF fixing sleeve 10 in the first fixing sleeve 3 .

[0053] As an optional implementation, the second limiting member includes:

[0054] The third fixing sleeve 8 is matched with the first fixing sleeve 3. The third fixing sleeve 8 is provided with a third threaded hole 17. The first fixing sleeve 3 is provided with a fourth threaded hole 18. The third threaded hole 17 is connected to the fourth threaded hole 18 by bolts.

[0055] The second slot 21 is provided on a side of the third fixing sleeve 8 close to the first fixing sleeve 3 , and the latch 7 is slidably connected in the first slot 22 through the second slot 21 .

[0056] In one embodiment of the present invention, referring to Figure 3 , Figure 4 The third fixing sleeve 8 is connected to the first fixing sleeve 3 and is used to block the latch 7.

[0057] As an optional embodiment, a first slot wall 20 is provided at the front end of the RF fixing sleeve 10, and a second slot wall 24 is provided at the front end of the second fixing sleeve 11. A groove is formed between the first slot wall 20 and the second slot wall 24. A protrusion 19 is fixedly connected to the RF head 1, and the protrusion 19 is rotatably connected in the groove.

[0058] In one embodiment of the present invention, referring to Figure 3 By installing the RF fixing sleeve 10 on the first fixing sleeve 3 , a groove is formed between the first slot wall 20 and the second slot wall 24 for lateral positioning of the latch pin 7 .

[0059] As an optional implementation, the connecting shaft includes a flexible shaft 23 , the flexible shaft 23 is located in the hose sleeve 9 , and the radio frequency head 1 is connected to the host 6 via the flexible shaft 23 .

[0060] In one embodiment of the present invention, referring to Figure 4, the radio frequency head 1 is combined with the flexible shaft 23 to ensure that the device can rotate flexibly inside the hip joint and can perform surgical operations on tissues more precisely.

[0061] As an alternative embodiment, the bolt 7 is in a C-shaped structure. One end of a spring 14 is fixedly connected inside the first card slot 22, and the other end of the spring 14 is in contact with the bottom end of the inner wall of the bolt 7.

[0062] In one embodiment of the present invention, referring to Figure 3 , the bolt 7 is in a C-shaped structure. After being inserted into the first card slot 22, it contacts the provided spring 14. In the initial state, the first latch 12 and the second latch 13 do not contact. During the process of continuing to move forward, the first latch 12 and the second latch 13 will come into contact. Since the operator continuously applies a forward force externally, the slope of the first latch 12 will squeeze the slope of the second latch 13. Due to the action of the spring 14, the bolt 7 will move upward. When continuing to move forward, the first latch 12 will reach the card slot position below the bolt 7. Due to the action of the spring 14, the bolt 7 will rebound, thereby clamping the first latch 12 and completing the fixation.

[0063] If disassembly is desired, manually pull the bolt 7 outward externally to move the bolt 7 upward, so that the second latch 13 below the bolt 7 no longer restricts the first latch 12, and then the user can pull the radio frequency device outwards.

[0064] As an alternative embodiment, inclined surfaces are provided on both the first latch 12 and the second latch 13, and the two inclined surfaces are in sliding contact.

[0065] In one embodiment of the present invention, referring to Figure 5 , Figure 6 , inclined surfaces are provided on both the first latch 12 and the second latch 13. When the two inclined surfaces contact, sliding displacement is generated through the provided inclined surfaces, thereby jacking up the bolt 7 upward.

[0066] As an alternative embodiment, the flexible shaft 23 includes a plurality of steel wires. One steel wire is located in the middle, and the remaining steel wires are wound layer by layer around the steel wire located in the middle to form a spring layer structure.

[0067] In one embodiment of the present invention, referring to Figure 7 , the flexible shaft 23 is composed of a single steel wire in the middle and several layers of steel wires tightly wound together to form a spring layer. The winding directions of adjacent steel wire layers are opposite. When torque is transmitted by the flexible shaft 23, one of the adjacent two layers of steel wires tends to be tightened and the other tends to be loosened, so that the steel wires between the layers tend to be pressed together. It is reasonable that the rotation direction of the shaft should make the surface steel wire tend to be tightened.

[0068] As an optional implementation, a fifth threaded hole 25 is formed on the continuum backbone 2 , and the fifth threaded hole 25 is connected to the third threaded hole 17 and the fourth threaded hole 18 through bolts.

[0069] In one embodiment of the present invention, referring to Figure 3 The fifth threaded hole 25 is arranged to correspond to the third threaded hole 17 and the fourth threaded hole 18, and is connected by bolts to achieve the connection between the first fixing sleeve 3 and the continuum backbone 2.

[0070] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0071] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention.
