Description

Technical Field

[0001] This utility model relates to the field of medical equipment, and in particular to a drainage device for deep infection after posterior spinal surgery. Background Technology

[0002] Deep surgical site infection (Dip / Dis) after spinal surgery is commonly treated with debridement combined with continuous irrigation and drainage. However, traditional surgical treatments involving thorough debridement, irrigation, and drainage often suffer from delayed irrigation, leading to the drying and blockage of drainage devices. This increases the incidence of complications, adds to patient suffering, and can even be life-threatening. Furthermore, existing drainage devices often lack proper anti-dislodgement designs, forcing patients to remain in bed for extended periods. Prolonged bed rest can cause patients to miss the optimal time for functional exercises, severely hindering early functional rehabilitation. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a deep infection drainage device for posterior spinal surgery that can use ultrasound-guided percutaneous puncture for precise catheter placement, ensure flushing of the pus cavity and negative pressure drainage during use, has a reasonable configuration, and does not affect the patient's rehabilitation training and daily activities during treatment.

[0004] The device includes an integrated conduit and connector.

[0005] The integrated catheter has a closed tip and includes a drainage channel, a flushing channel, and a bending control channel inside.

[0006] The connector includes a drainage connector, a flushing connector, and a bending control connector; the drainage connector is connected to the drainage channel, the flushing connector is connected to the flushing channel, and a drainage hole and a flushing hole are respectively provided on the drainage channel and the flushing channel.

[0007] A traction rope is threaded through the upper part of the bending control channel, and the tail end of the traction rope extends out of the bending control channel. A traction rope positioning device is provided between the traction rope and the bending control channel.

[0008] The effect achieved is that when the integrated catheter is inserted into the cavity and the traction rope is pulled, the end of the rope is bent into a loop, which prevents the entire catheter from coming out. This also ensures that the device can be worn without affecting rehabilitation training. In this case, drainage and flushing are performed through the drainage hole and flushing hole, respectively.

[0009] The beneficial effects of this invention are that it fills a gap in the existing technology. Based on the drainage channel connected to a drainage pump and the flushing channel connected to a flushing pump, the abscess cavity can be flushed and drained at regular intervals. In particular, the design based on the bending control structure allows patients to get out of bed and move around during treatment, effectively preventing complications such as lower extremity deep vein thrombosis, hypostatic pneumonia, constipation, and bedsores caused by prolonged bed rest. It also alleviates the patient's psychological stress, improves appetite, enhances nutritional levels, and accelerates recovery. Attached Figure Description

[0016] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0017] Reference Figure 1 , Figure 2 The present invention provides a deep infection drainage device after posterior spinal surgery, comprising an integrated catheter and a connector.

[0018] The integrated catheter has a closed tip and includes a drainage channel, a flushing channel, and a bending control channel inside.

[0019] The connector includes a drainage connector 3, a flushing connector 4, and a bending control connector 2; the drainage connector 3 is connected to the drainage channel, the flushing connector 4 is connected to the flushing channel, and a drainage hole 5 and a flushing hole 6 are respectively provided on the drainage channel and the flushing channel.

[0020] A traction rope 1 is threaded through the upper part of the bending control channel. The tail end of the traction rope 1 extends out of the bending control channel, and a traction rope positioning device is provided between the traction rope 1 and the bending control channel.

[0021] The effect achieved is that when the integrated catheter is inserted into the cavity, the traction rope 1 is pulled, and the end of the rope is bent into a loop, which prevents the entire catheter from coming out. This also achieves the goal of ensuring that the device can be worn without affecting rehabilitation training. In this case, drainage hole 5 and flushing hole 6 are used for drainage and flushing, respectively.

[0022] In Example 1, the connector is a three-way connector, and the drainage connector 3 and the flushing connector 4 are both quick connectors. The drainage channel, the flushing channel and the bending control channel are set independently.

[0023] Furthermore, a one-way valve is provided inside the flushing hole 6.

[0024] The effect achieved is to optimize the equipment structure, facilitate the connection of medical devices, and ensure that the channels are not interconnected, thus preventing pus from flowing back into the flushing channel and reducing the risk of infection.

[0025] Furthermore, the drainage connector 3 is connected to the drainage pump, the flushing connector 4 is connected to the flushing pump, and the flushing pump is equipped with flushing fluid.

[0026] Preferably, the flushing pumps are all electric pumps or manual pumps, and the drainage pumps are negative pressure drainage balls or electric pumps.

[0027] The effect achieved in this way is that by controlling the two pumps, timed flushing and continuous drainage are carried out. In particular, during the continuous drainage process, it is beneficial to the adhesion of the cavity wall and improve the rehabilitation efficiency.

[0028] In Example 2, a removable guide rod is provided inside the drainage connector 3 or flushing connector 4. The guide rod is made of metal and its length is greater than the total length of the integrated catheter and connector.

[0029] The effect achieved is that when the device is inserted into the abscess cavity, the integrated catheter portion is supported by the guide rod, which facilitates reaching the target position.

[0030] In Example 3, the bending control channel is provided with a first assembly hole and a second assembly hole at its top and upper part, respectively, that is, the second assembly hole is below the first assembly hole;

[0031] One end of the traction rope 1 is fixed in the bending control channel, and from its fixed end, the traction rope 1 passes through the bending control channel and exits through the first mounting hole at its top, and then passes through the second mounting hole at its upper part into the bending control channel. Its tail end passes through the through hole opened on the bending control connector 2 and is fixedly connected to the positioning device of the traction rope 1.

[0032] The effect achieved in this way is as shown in the attached diagram of the instruction manual. Figure 1 , Figure 3 and Figure 4 As shown, the traction rope 1 part forms a rope loop. Based on its assembly form, when the traction rope 1 is pulled, the first assembly hole is actually pulled close to the second assembly hole. That is, the integrated guide tube part between the first assembly hole and the second assembly hole forms a loop to prevent it from coming off.

[0033] Furthermore, the bending control connector 2 is an externally threaded pipe, and an adjusting screw sleeve 21 is provided on the bending control connector 2. The adjusting screw sleeve 21 is provided with a rotatable free ring. One end of the traction rope 1 is fixed in the bending control channel, and the other end is fixed on the free ring.

[0034] The effect achieved is that the bending control joint 2, in conjunction with the rotation of the screw sleeve, enables the traction action of the traction rope 1. Furthermore, based on the self-locking structure between the threaded screws, it can ensure that the traction rope 1 does not automatically return to its original position after being pulled, thus ensuring that the integrated conduit does not fall off as a whole.
