Description

Technical Field

[0001] The present invention relates to the technical field of puncture needles, and more particularly to a bone channel visualization puncture needle. Background Art

[0002] Puncture techniques are widely used in minimally invasive orthopedic surgeries, such as pedicle screw placement, minimally invasive pelvic surgery, greater trochanter puncture, and placement of intramedullary fixation devices. However, traditional puncture needles have the following problems: 1. The puncture process cannot be visually observed, relying on the physician's experience and preoperative imaging, which can easily lead to puncture deviation and increase surgical risk; 2. During the puncture process, the fracture reduction cannot be assessed in real time, affecting the surgical outcome; 3. The puncture needle's structural design is relatively simple, unable to meet the needs of various orthopedic surgeries, and lacks effective flushing and suction functions, which can easily lead to blood accumulation or tissue residue at the puncture site.

[0003] In addition, there are several patents for visualization puncture needles on the market, such as: 1) A visualization puncture needle (patent number: CN202321421117.8), which achieves visualization of intracranial puncture by providing a visual cavity, injection cavity, and suction cavity within the puncture sleeve. However, this technology is mainly used for intracranial surgery and is not suitable for orthopedic puncture. 2) A visualization puncture needle for neurosurgery (patent number: CN218419989U), which achieves visualization of the puncture needle by providing a control mechanism, a pressurizing mechanism, and a binding assembly.

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0033] It should be understood that terms such as “having”, “including” and “comprising” used herein do not preclude the existence or addition of one or more other elements or combinations thereof.

[0034] like Figure 1-Figure 3As shown, the present invention provides a bone channel visualization puncture needle, comprising: a puncture needle body 100, comprising a working section 1 and a handle 2. The handle 2 is mounted at one end of the working section 1, and a camera module 3 is mounted at the other end of the working section 1. A flushing hole 10 is provided, and the flushing hole 10 is located on one side of the camera module 3 so that the flushing hole 10 does not block the camera module 3. The camera module 3 is electrically connected to the handle 2, so the handle 2 can control the operation of the camera module 3, for example, to take photos or videos of the lesion during minimally invasive orthopedic surgery. Furthermore, a flushing and aspiration catheter 21 is mounted on the handle 2, which is connected to the working section 1. During use, the flushing and aspiration catheter 21 can also be used to flush and aspirate the working section 1, ensuring a clear view of the image obtained by the camera module 3 during operation. The flushing and aspiration catheter 21 is turned on and off by rotating a three-way valve 211, allowing for water flushing or blood aspiration to maintain a clear view of the puncture site.

[0035] The puncture needle body 100 with the above-mentioned structure allows for intuitive observation during the puncture process, reducing excessive reliance on the doctor's experience, reducing the chance of puncture deviation, and thus reducing surgical risks; during the puncture process, the conditions of the bone channel and fracture ends can be evaluated in real time, reducing the risk of the puncture needle breaking through the bone cortex and affecting the surgical effect; the puncture needle body 100 has flushing and suction functions to avoid blood accumulation or tissue residue at the puncture site.

[0036] Furthermore, the puncture needle body 100 of the above structure is suitable for a variety of orthopedic surgical scenarios, including but not limited to: pedicle puncture, used for spinal surgery such as pedicle screw implantation; puncture operations in minimally invasive pelvic surgery; puncture of the apex of the greater trochanter of the femur, used in femoral surgery; puncture of various intramedullary devices, such as implantation of intramedullary nails; exploration of fracture end reduction status, real-time evaluation of reduction effect, and assistance in surgical decision-making.

[0037] It can be understood that the camera module 3 includes a camera 31 and two light sources 32. The two light sources 32 are respectively located on both sides of the camera 31, so that the camera can obtain a clear image field of view.

[0038] Furthermore, some embodiments of the present invention provide a specific structure of the aforementioned working section 1. Here, the working section 1 includes a straight section 11 and an arcuate section 12. One end of the arcuate section 12 is connected to the other end of the straight section 11. The arcuate section 12 is located on one side of the camera module 3. The camera 31 of the camera module 3 must not protrude beyond the inclined surface of the arcuate section to avoid stress concentration with the tissue. The image captured by the camera 31 can cover the other (distal) end of the working section 1.

[0039] At one end of the arcuate segment 12 is an irrigation and suction opening 13 corresponding to the irrigation hole 10. Therefore, during use, the straight-through segment 11 provides a mounting location for the camera module 3 and an irrigation channel. The arcuate segment 12 helps the puncture needle enter the bone channel more accurately, reducing damage to surrounding tissue. When the irrigation hole 10 is used for irrigation or suction, the irrigation and suction opening 13 performs the above functions.

[0040] Furthermore, the arc segment 12 is bent to one side at a 6-7° angle and gradually becomes thinner from one end to the other, narrowing to a width of 1.5-2 mm and a length of 15-40 mm. Specifically, the arc segment 12 is flat, narrowing in width, with an upward curved tip at an angle of approximately 6 degrees and a length of approximately 30 mm. This design helps the puncture needle more accurately enter the bone canal and minimizes damage to surrounding tissue.

[0041] Furthermore, the straight-through section 11 is a hollow circular tube with a diameter of 3.5 mm or less and a length of 20-60 cm. Specifically, the straight-through section 11 is a circular tube approximately 20 cm long and 3.5 mm in diameter. The surface of the working section 1 is marked with a scale in multiples of 0.5 cm, allowing the doctor to precisely control the puncture depth.

[0042] Furthermore, a control module (not shown) is installed within the handle portion 2, and a first button 22 and a second button 23 are installed on the outer wall of the handle portion 2. Here, the first button 22, the second button 23, and the camera module 3 are electrically connected to the control module. The first button 22 can be used for taking photos, and the second button 23 can be used for recording videos, which facilitates the doctor to record key images and videos during the puncture process.

[0043] Furthermore, the handle 2 is equipped with a balancer 24 and a data cable 25. The balancer 24 displays the angle of the puncture needle in real time, helping the doctor to accurately control the puncture direction and avoid accidental injury to surrounding tissue. The data cable 25 is electrically connected to the control module. The data cable 25 (with a Type-C interface 251) is connected to a mobile phone or monitor, allowing the doctor to view and store puncture images in real time.

[0044] Of course, it is understandable that the control module also has Bluetooth function to realize wireless transmission function.

[0045] Generally speaking, after the above-mentioned puncture needle body 100 is used, it is necessary to separate the external water supply part and the flushing branch 212 of the flushing tube 21, and then the puncture needle body 100 needs to be processed in the next step. When the external water supply part and the flushing branch 212 are separated, residual flushing water often flows out of the water pipe of the external water supply part. Moreover, the water pipe and the flushing branch 212 are mostly screwed together. Frequent rotation and opening will cause thread slippage and loosening. When the flushing water pressure is high, the flushing water will leak out from the connection part, making it inconvenient for medical staff to operate and the flushing effect is poor.

[0046] like Figure 4-12 As shown, further, in some embodiments of the present invention, the flushing branch pipe 212 of the flushing pipe 21 is connected to the external water supply part 200 through the water guide module 30, and the water guide module 30 of this structure includes a male water guide part 40 and a female water guide part 50, wherein the male water guide part 40 is installed on the outer end of the flushing branch pipe 212, and the female water guide part 50 is installed on the water supply pipe of the external water supply part, so that the male water guide part 40 and the female water guide part 50 are connected to each other. The water guide module 30 of the above structure replaces the screw connection method of the prior art, avoiding slippage and loosening caused by turning to open, so when the flushing water pressure is high, it will not cause the flushing water to leak out of the connection part, making it convenient for medical staff to operate and providing a flushing effect.

[0047] Furthermore, the male-end water-guiding portion 40 of the above-mentioned structure includes a male-end water-guiding tube 41 and a first inner water-guiding tube 42, wherein the first inner water-guiding tube 42 is partially fixedly installed in the male-end water-guiding tube 41, and a driving member 43 is installed in the first inner water-guiding tube 42. The female-end water-guiding portion 50 of the above-mentioned structure includes a female-end water-guiding tube 51, a second inner water-guiding tube 52, and an inner blocking cap tube 53, wherein the second inner water-guiding tube 52 is penetrated and installed in the female-end water-guiding tube 51, and a guide groove 510 for accommodating the first inner water-guiding tube 42 is provided between the second inner water-guiding tube 52 and the female-end water-guiding tube 51. The inner blocking cap tube 53 is movably installed in the second inner water-guiding tube 52, so that the first inner water-guiding tube 42 can be partially connected to the guide groove 510 when in use, so that the first inner water-guiding tube 42 enters the second inner water-guiding tube The male water guide part 40 and the female water guide part 50 are connected to each other, and the driving member 43 is used to push against the inner blocking cap barrel 53, and the inner blocking cap barrel 53 moves inward in the second inner water guide barrel 52, and the inner blocking cap barrel 53 no longer blocks the inside of the second inner water guide barrel 52, so that the first inner water guide barrel 42 and the second inner water guide barrel 52 are in a connected state, so that the flushing water enters the puncture needle body 100 through the male water guide part 40 and the female water guide part 50 for easy flushing; on the contrary, when the male water guide part 40 and the female water guide part 50 are separated, the driving member 43 no longer acts on the inner blocking cap barrel 53, and the inner blocking cap barrel 53 is again blocked in the female water guide part 50, so as to prevent residual flushing water from flowing out and affecting the use of medical staff.

[0048] Furthermore, some embodiments of the present invention provide a specific structure of the driving member 43, wherein the driving member 43 of the structure includes a driving cap 431 and a driving column 432, wherein the driving cap 43 is installed in the first inner water guide cylinder 42, and the driving column 432 is installed on the driving cap 431, and a plurality of inner water holes 433 are opened on the driving cap 431, and a water blocking ring 434 corresponding to the second inner water guide cylinder 52 is also installed on the brim of the driving cap 431, so when the first inner water guide cylinder 42 enters the second inner water guide cylinder 52 and the female end guide cylinder 53, the female end guide cylinder 53 is opened. When the water cylinder 51 is between the second inner water-conducting cylinder 52 and the first water-conducting cylinder 42, the driving column 432 presses against the inner blocking cap cylinder 53, so that the inner blocking cap cylinder 53 no longer blocks the second inner water-conducting cylinder 52. When flushing, the flushing water flows through the inner blocking cap cylinder 53 to the driving cap 431, and flows through multiple inner water holes 433 into the puncture needle body 100 to achieve flushing; in addition, the second inner water-conducting cylinder 52 enters the first inner water-conducting cylinder 42 and presses against the water-blocking ring 434, so as to prevent the flushing water from seeping out.

[0049] Furthermore, in some embodiments of the present invention, a trapezoidal water guide hole 521 and an intermediate guide cavity 522 are provided in the second inner water guide cylinder 52, wherein the opening direction of the trapezoidal water guide hole 521 is toward the first inner water guide cylinder 42, and a blocking groove 523 corresponding to the blocking end 530 of the inner blocking cap cylinder 53 is provided at the inner end of the trapezoidal water guide hole 521. An inner guide ring seat 524 is provided in the second inner water guide cylinder 52, and the inner blocking cap cylinder 53 is installed on the inner guide ring seat 524 through an inner spring 531. A plurality of first water holes 532 corresponding to the intermediate guide cavity 522 are provided on the inner blocking cap cylinder 53, and the first water holes 532 are close to the inner blocking cap cylinder 530. The sealing end 530 of the tube 53, so when the inner spring 531 supports the inner sealing cap tube 53 in a sealing state, the sealing end 530 enters the sealing groove 523 to achieve the sealing of the trapezoidal water guide hole 521 to prevent the flushing water from leaking out, and the middle guide cavity 522 can temporarily store the flushing water; and when the driving member 43 contacts the blocking end 530, it pushes it, so that the blocking end 530 moves toward the inside of the second inner water guide tube 52, so that there is a gap between the blocking end 530 and the blocking groove 523, and the flushing water flows into the gap through the first water hole 532, and then enters the trapezoidal water guide hole 521 to achieve conduction.

[0050] Furthermore, in some embodiments of the present invention, a plurality of axial guide grooves 511 are provided on the inner wall of the female end water guide tube 51, a circumferential guide groove 512 is provided at the inner end of the axial guide groove 511, and the circumferential guide groove 512 is communicated with the inner sealing hole 513 of the female end water guide tube 51, a limiting mechanism 54 is installed in the inner sealing hole 513, and a guide seat 421 is provided on the outer end of the first inner water guide tube 42, which can be moved along the axial guide groove 511 into the circumferential guide groove 512 and connected to the top of the limiting mechanism 54. When the above action realizes that the first inner water guide tube 42 is installed in the guide groove 510, and the guide seat 421 is limited by the above-mentioned limiting mechanism 54, when used by medical staff, the first inner water guide tube 42 can be prevented from relative rotation in the guide groove 510, and the first inner water guide tube 42 can be prevented from loosening and causing the flushing water to seep out.

[0051] Furthermore, some embodiments of the present invention provide a specific structure of the limiting mechanism 54, where the limiting mechanism 54 of this structure includes a limiting baffle 541, a T-shaped limiting guide column 542, and a limiting telescopic guide column 543. The limiting baffle 541 is installed in the inner blocking hole 513, the T-shaped limiting guide column 542 is passed through the limiting baffle 541, and the limiting telescopic guide column 543 is passed through the limiting hole 514. Here, the inner blocking hole 513 is connected to the circumferential guide groove 512 through the limiting hole 514, and the T-shaped limiting guide column 542 pushes against the limiting telescopic guide column 543, so that the limiting telescopic guide column 543 pushes against the guide seat 421 and limits the guide seat 421. In this way, when used by medical staff, the guide seat 421 will not be separated from the circumferential guide groove 512, and the flushing water will not seep out.

[0052] Furthermore, some embodiments of the present invention provide a specific structure of a telescopic guide post 543. Here, the telescopic guide post 543 includes a circumferential limit guide post 544 and a limit spring 545. The limit spring 545 is mounted on the circumferential limit guide post 544 and abuts between the limit hole 514 and the stop rod 546 of the circumferential limit guide post 544. Therefore, when the telescopic guide post 543 is pushed by the T-shaped limit guide post 542, it moves into the limit hole 514, thereby securing the guide seat 421. Corresponding inclined guide walls can be designed on the T-shaped limit guide post 542, the circumferential limit guide post 544, and the guide seat 421 to achieve this securing effect. The limit spring 545 facilitates the subsequent release of the circumferential limit guide post 544 from the limit position of the guide seat 421.

[0053] Furthermore, in some embodiments of the present invention, an intermediate water hole 525 corresponding to the inner sealing hole 513 is provided on the second inner water guide tube 52, and correspondingly, a second water hole 533 corresponding to the intermediate water hole 525 is provided on the inner sealing cap tube 53. Therefore, when flushing water is supplied to the inner sealing cap tube 53, it enters the intermediate water hole 525 through the second water hole 533 and continues to enter the inner sealing hole 513, and then the flushing water pushes against the T-shaped limit guide column 542, thereby increasing the limiting and fixing effect of the limiting mechanism 54 on the guide seat 421, and then the male end water guide part 40 and the female end water guide part 50 will not loosen to cause the flushing water to leak out, which is convenient for medical staff to use.

[0054] In summary, the puncture needle body 100 of the above structure also has the following beneficial effects:

[0055] 1. Improve the success rate of surgery: Through visual operation, doctors can complete puncture more accurately, reduce the risk of surgical failure due to puncture deviation, and improve the success rate of surgery.

[0056] 2. Reduce patient pain: Precise puncture operation reduces damage to surrounding tissues and reduces the incidence of postoperative pain and complications in patients.

[0057] 3. Promote the development of minimally invasive orthopedic technology: The present invention provides an efficient and safe puncture tool for minimally invasive orthopedic surgery, which helps to promote the further development and application of minimally invasive orthopedic technology.
