Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically to an arthroscopic irrigation stand. Background Technology

[0002] Arthroscopic surgery is a highly precise, minimally invasive surgical technique that involves inserting a camera and miniature instruments through a millimeter-sized incision in the skin. Under monitor guidance, it diagnoses and treats injuries or inflammation of the meniscus, ligaments, and cartilage within joints such as the knee, shoulder, and ankle. Compared to traditional open surgery, arthroscopic surgery offers advantages such as less trauma, less postoperative pain, and faster recovery, and is therefore widely used in clinical practice. However, the compatibility, stability, and portability of saline irrigation devices used in arthroscopic surgery remain unresolved.

[0003] In existing technologies, the support frames for saline irrigation devices can be divided into two types according to their complexity: The first type is the ordinary infusion stand, which uses a single-rod telescopic structure with a lightweight base, resulting in poor stability and a tendency to tip over. Ordinary infusion stands suspend saline bags via hooks and rely on manual, rough height adjustment without a dedicated tubing fixing structure, leading to insufficient height adjustment precision and unstable control of irrigation pressure. Furthermore, the lack of a fixing and limiting structure for the tubing makes it prone to tangling and displacement, interfering with the surgery. The second type is a dedicated arthroscopic irrigation tower, which features electric lifting and pressure monitoring functions, offering higher adjustment precision. However, it is more expensive and has a cumbersome operation process, making it unaffordable for primary healthcare institutions and requiring highly skilled medical personnel. Dedicated irrigation towers are also bulky, making them inconvenient to move and store.

[0004] In summary, there is a need in the arthroscopic irrigation stand that offers better stability, more precise and convenient height adjustment, smaller size, and lower cost. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide an arthroscopic irrigation stand, which uses a built-in counterweight base combined with a manually adjustable telescopic rod to improve stability, adjustment accuracy and convenience, uses an adjustable hanging rope assembly to fix the saline bag to improve the adjustment accuracy of the saline bag, and uses a hook installed on the telescopic rod to achieve flexible fixation of the irrigation pipeline.

[0006] To achieve the above objectives, the present invention provides an arthroscopic irrigation support, comprising a base, a support assembly, and an adjustable hanging rope assembly. The support assembly includes a first telescopic rod and a second telescopic rod mounted on the top of the base. The telescopic directions of the first and second telescopic rods are parallel to each other. The top of the second telescopic rod is connected to the middle of the first telescopic rod. A crossbeam is mounted on the top of the first telescopic rod. The adjustable hanging rope assembly is connected to the crossbeam and a saline bag is hung on the adjustable hanging rope assembly. Several hooks are fixedly fitted on the first and second telescopic rods, and the adjustable hanging rope assembly is hooked to the hooks.

[0007] Preferably, the base has a counterweight cavity with an upper opening, and the counterweight cavity contains a plurality of counterweights.

[0008] Preferably, anti-slip pads are attached to the four corners of the bottom of the base.

[0009] Preferably, a set of rollers is fixedly installed on the bottom rear side of the base.

[0010] Preferably, the first telescopic rod includes a first base rod and a first upper rod, the first base rod is welded and fixed to the base, and the first upper rod is slidably inserted into the first base rod.

[0011] Preferably, the second telescopic rod includes a second bottom rod and a second top rod. The second bottom rod is welded and fixed to the base, and the second top rod is slidably inserted into the second bottom rod. The top of the second top rod extends obliquely and is connected to the first top rod.

[0012] Preferably, the section above the connection between the first upper rod and the second upper rod forms a first upper section, the second upper rod has an inclined section, and the hooks are respectively installed on the first upper section and the inclined section.

[0013] Preferably, the adjustable hanging rope assembly includes a hanging rope and a fixed pulley assembly. The fixed pulley assembly is sleeved on the crossbeam, and the hanging rope is sleeved on the fixed pulley assembly. One end of the hanging rope is connected to a saline bag hook for hooking the saline bag, and the other end is connected to a hanging rope winder. The hanging rope has several rope buckles, and the hanging rope is hooked to the hook through the rope buckles.

[0014] Preferably, the fixed pulley assembly includes a beam connector sleeved on the beam and a fixed pulley rotatably connected to the beam connector. The fixed pulley is located at the bottom of the beam connector, and the hanging rope is draped on the fixed pulley.

[0015] Preferably, the top of the first telescopic rod is detachably mounted to the crossbeam by bolts.

[0016] Compared with existing technologies, the advantages of the arthroscopic irrigation stand disclosed in this invention are as follows: the arthroscopic irrigation stand has better stability, effectively preventing tipping during surgery and improving surgical safety; the arthroscopic irrigation stand uses a double telescopic rod to form a support, which enhances structural stability and improves the convenience of adjustment; the arthroscopic irrigation stand uses an adjustable hanging rope assembly to fix the saline bag, allowing for fine adjustment of the saline bag's height, thereby stabilizing the irrigation pressure and preventing pressure fluctuations from affecting the surgical field of vision; the arthroscopic irrigation stand uses a hook that can be rotatably mounted on the telescopic rod, which can flexibly fix the irrigation tubing, preventing tubing entanglement and displacement, eliminating interference with surgical operations, and ensuring the smooth progress of the surgery; the arthroscopic irrigation stand has a low cost.

Detailed Implementation

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] like Figure 1 As shown, this application discloses an arthroscopic irrigation support, comprising a base 1, a support assembly 2, and an adjustable hanging rope assembly 3. The support assembly 2 includes a first telescopic rod 21 and a second telescopic rod 22 mounted on the top of the base 1. The telescopic directions of the first telescopic rod 21 and the second telescopic rod 22 are parallel to each other. The top of the second telescopic rod 22 is connected to the middle of the first telescopic rod 21. The top of the first telescopic rod 21 is detachably mounted on a crossbeam 23 via bolts. The adjustable hanging rope assembly 3 is installed in conjunction with the crossbeam 23, and a saline bag 5 is hung on the adjustable hanging rope assembly 3. Several hooks 4 are fixedly sleeved on the first telescopic rod 21 and the second telescopic rod 22. The adjustable hanging rope assembly 3 can be hooked to the hooks 4 to achieve position adjustment and limiting fixation of the adjustable hanging rope assembly 3, thereby achieving height adjustment of the saline bag 5. At the same time, the irrigation pipeline can also be fixed by the hooks 4 to avoid tangling or displacement of the irrigation pipeline and eliminate interference with the surgical operation.

[0027] See Figure 2 The base 1 has a counterweight cavity 10 with an opening at the top, and the counterweight cavity 10 contains several counterweights 100. Preferably, the base 1 is a cuboid with a cross-sectional side length of 30-40cm, and the counterweights are preferably 2kg sandbags or metal blocks. The cross-sectional area of ​​the base 1 is larger than that of a regular IV stand. Combined with the internal counterweights to increase the overall weight, the stability of the base 1 can be effectively improved, effectively preventing the stand from tipping over during surgery, thereby improving the safety of the operation. The counterweights 100 can be easily inserted or removed through the top of the counterweight cavity 10. The counterweights can be removed when moving and inserted again when needed.

[0028] See Figure 3 Anti-slip pads 11 are attached to the four corners of the bottom of the base 1. Each anti-slip rubber pad 11 is a cuboid with a side length of 5cm. By setting the anti-slip pads 11, the friction can be increased, further improving the stability of the base and effectively preventing the books in the support from tipping over.

[0029] A set of rollers 12 are fixedly installed on the bottom rear side of the base 1. When it is necessary to move the arthroscopic irrigation bracket, the user can tilt the base 1 by operating the support assembly 2 and make the rollers 12 contact the ground to complete the movement operation easily and conveniently.

[0030] See Figure 1 and Figure 2 The first telescopic rod 21 includes a first base rod 211 and a first upper rod 212. The first base rod 211 is welded and fixed to the base 1. The first upper rod 212 is slidably inserted into the first base rod 211. The first base rod 211 has several vertically arranged adjustment holes 2111. The first upper rod 212 has spring clips aligned with the adjustment holes 2111. Preferably, the spacing between the adjustment holes 2111 is 10cm. The structure of the spring clips and adjustment holes 2111 allows the operator to adjust and quickly lock the height by one person to adapt to different operating table heights and surgical operation needs, effectively improving surgical efficiency.

[0031] The second telescopic rod 22 includes a second base rod 221 and a second upper rod 222. The second base rod 221 is welded and fixed to the base 1. The second upper rod 222 is slidably inserted into the second base rod 221. The top of the second upper rod 222 extends obliquely and connects to the first upper rod 212. The second base rod 221 has several vertically arranged adjustment holes 2211. The second upper rod 222 has spring clips aligned with the adjustment holes 2211. Preferably, the spacing between the adjustment holes 2211 is 10cm. The structure of the spring clips and adjustment holes 2211 allows the operator to adjust and quickly lock the height to adapt to different operating table heights and surgical operation needs, effectively improving surgical efficiency. The first telescopic rod 21 and the second telescopic rod 22 together constitute a double-pillar structure, which can effectively enhance the structural stability of the pillar assembly 2. Both telescopic rods use a spring clip and adjustment hole adjustment structure, which can quickly adjust and lock the height.

[0032] The section above the connection between the first upper rod 212 and the second upper rod 222 forms the first upper section 2121. The second upper rod 222 has an inclined section 2221. Since the first upper section 2121 and the inclined section 2221 do not participate in height adjustment, the hook 4 is installed on the first upper section 2121 and the inclined section 2221 respectively to avoid interference with height adjustment.

[0033] See Figure 1 , Figures 4 to 6 The adjustable hanging rope assembly 3 includes a hanging rope 31 and a fixed pulley assembly 32. The fixed pulley assembly 32 is sleeved on the crossbeam 23, and the hanging rope 31 is sleeved on the fixed pulley assembly 32. One end of the hanging rope 31 is connected to a saline bag hook 311 for hooking the saline bag 5, and the other end is connected to a hanging rope winder 312. The hanging rope has several rope buckles 313, and the hanging rope 31 is hooked to the protrusion 41 of the hook 4 through the rope buckles 313. By operating different rope buckles 313 to hook different hooks 4, the height of the saline bag 5 can be changed. The hanging rope winder 312 is hooked on the hook 4, and the hanging rope winder 312 can wind up and store the excess hanging rope 31 inside, avoiding interference and making the operation convenient and quick.

[0034] The fixed pulley assembly 32 includes a beam connector 321 sleeved on the beam 23 and a fixed pulley 322 rotatably connected to the beam connector 321. The fixed pulley 322 is located at the bottom of the beam connector 321, and the hanging rope 31 is laid on the fixed pulley 322. Using a fixed pulley can reduce the wear of the hanging rope and reduce the cost of use.

[0035] During assembly of the arthroscopic irrigation support, the counterweight 100 is first placed into the counterweight cavity 10; then, the first base rod 211 and the second base rod 221 are vertically inserted into the pre-reserved interface on the base 1 and fixed by welding points to ensure that the support is parallel and perpendicular to the base 1; then, the crossbeam 23 is bolted to the top of the first upper rod 212, and the fixed pulley assembly 32 is installed on the crossbeam 23; then, the hanging rope 31 is passed through the fixed pulley 322 and hung on the saline bag 5; then, the height of the saline bag 5 is adjusted by the hanging rope 31 and the hanging rope 31 is fixed to the hook 4 by the rope buckle 313.

[0036] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
