Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an interventional delivery device. Background Technology

[0002] Interventional therapy, guided by medical imaging equipment, uses puncture needles, catheters, and other interventional devices to diagnose and treat diseases. It is characterized by accurate localization, minimal invasiveness, few complications, high efficacy, rapid onset of action, and strong repeatability. Interventional therapy has become the third major clinical treatment method, alongside internal medicine and surgery. There are many techniques in interventional therapy, which can be divided into endovascular and non-vascular interventional techniques.

[0003] While the interventional delivery device disclosed in Chinese Utility Model Patent Application Publication CN210301985U involves slotting a imaging ring into the imaging section, this utility model offers a more convenient and simpler approach. It involves narrowing the distal end of the delivery sheath and directly heat-melting the imaging ring into its outer surface to form the imaging section. This results in a better forming effect. However, existing devices do not address the issue of surgeons needing to hold the delivery device with one hand while connecting it to the medical device during surgery. This method is time-consuming and labor-intensive, requiring one hand. Furthermore, liquids can easily adhere to the delivery device's surface when it is removed, potentially contaminating the surgeon's hands or the bed. Even after securing the delivery device, collisions can cause it to rub against internal organs, leading to discomfort. Additionally, the device's position cannot be effectively adjusted based on the patient's condition or the surgeon's surgical habits. Therefore, this application provides an interventional delivery device to meet these needs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an interventional delivery device to solve the problems of the existing hand-held delivery device for doctors, which is time-consuming and laborious, and the liquid adhering to the surface of the delivery device is easy to drip onto the doctor's hands when the delivery device is pulled out, causing contamination of the doctor's hands.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] An interventional delivery device includes a support base, a limit rod inserted inside the support base, a fixed base slidably connected inside the support base, a spring telescopic rod fixedly connected inside the fixed base, a clamping plate fixedly connected to one end of the spring telescopic rod, a sponge block clamped inside the clamping plate, a main tube clamped inside the clamping plate, a developing ring fixedly connected to the surface of the main tube, a developing hole fixedly connected to the surface of the main tube, a delivery channel provided inside the main tube, a positioning seat fixedly connected to one side of the fixed base, a positioning rod inserted inside the positioning seat, a disc rotatably connected to the surface of the fixed base, a connecting seat fixedly connected to the lower surface of the disc, a soft pad fixedly connected to the lower surface of the connecting seat, and a fixing restraint strap fixedly connected to one side of the disc.

[0007] Optionally, a plurality of limiting holes are sequentially formed on one side of the support base from top to bottom, and a hole is formed on one side of the fixing base near the lower part, wherein the limiting holes and the hole are of the same size.

[0008] Optionally, the number of spring telescopic rods is four, the number of clamps and sponge blocks is two each, and the main tube is located between the two sponge blocks.

[0009] Optionally, the developing ring is embedded in the surface of the main tube, and the connection between the surface of the developing ring and the surface of the main tube is a smooth transition.

[0010] Optionally, one end of the main tube is bent, the main tube is L-shaped, and the developing ring and developing hole are both located at the bent position on the surface of the main tube.

[0011] Optionally, the fixing base has a mating hole inside, and the fixing base is located inside the mating hole near the center.

[0012] Optionally, the connecting seat is located near the center of the lower surface of the disk, and the soft pad is C-shaped.

[0013] Optionally, the upper surface of the disk is provided with a plurality of positioning holes, and the disk is slidably connected to the positioning rod through the positioning holes.

[0014] Optionally, the fixed restraint strap has ventilation holes inside, and a Velcro front surface is fixedly connected to the lower surface of the fixed restraint strap. A docking restraint strap is fixedly connected to the other side of the disc. The docking restraint strap has air inlet inside, and a Velcro back surface is fixedly connected to the upper surface of the docking restraint strap. The Velcro front surface and the Velcro back surface are mutually compatible.

[0015] Optionally, there are several vent holes and several air inlets, and the air inlets and vent holes are the same size.

[0016] Compared with the prior art, this utility model has at least the following beneficial effects:

[0017] In the above scheme, a compression spring telescopic rod is used to move the clamping plates. The main body tube is then placed between the two clamping plates. The pressure is then released by the spring telescopic rod, causing the two clamping plates to clamp and fix the main body tube. By separating the limiting rod from the support and fixing seats, and then sliding the fixing seats up and down, the height of the fixing seats and the main body tube can be adjusted. Once the fixing seats and the main body tube are adjusted to a suitable height, the limiting rod is passed through the support and fixing seats to fix the fixing seats and the main body tube. By separating the positioning rod from the disc, and then rotating the support seat, once the support seat and the main body tube have rotated to a suitable angle, the positioning rod is passed through... The support base and disc secure the support base and main tube. The imaging ring, imaging hole, and delivery channel assist doctors in delivering medical devices. This reduces the risk of the delivery device being bumped after being secured, which could cause discomfort to the patient if it collided with internal organs. It also reduces the inability to effectively adjust the position of the delivery device according to the patient's condition or the doctor's surgical habits. The system effectively secures the exposed delivery device after it is fixed inside the patient's body and allows for effective adjustment of its position according to the patient's condition or the doctor's surgical habits.

[0018] By incorporating a sponge block, liquid adhering to the surface of the main tube can be collected when the doctor removes it from the patient's body. After collection, the sponge block can be separated from the splint, the contaminated sponge block can be discarded, and a new sponge block can be installed inside the splint. This reduces the likelihood of liquid adhering to the surface of the delivery device when it is removed from the patient's body, and the potential for this liquid to drip onto the doctor's hands or the bed, causing contamination. The sponge block effectively absorbs and collects the liquid from the surface of the main tube when it is removed.

[0019] By incorporating a soft pad that contacts the patient's arm or leg, and then tightening the fixation straps and connecting straps to adhere them to the patient's arm or thigh, the Velcro front and back are then attached, fixing the disc to the arm or leg at the desired surgical location. Through ventilation holes and air inlets, air can be released from the restrained area while the fixation straps and connecting straps are in place, reducing patient discomfort. The soft pad also minimizes marks from the restraints. Furthermore, it reduces the need for the surgeon to hold the delivery device with one hand while connecting it to the desired medical device during surgery, a time-consuming and laborious process requiring one hand. This allows the surgeon to place the main tube inside the patient's body and then fix one end of the main tube, making it easier for the surgeon to retrieve and deliver the desired medical device.

[0036] like Figures 1-6 As shown, an embodiment of this utility model provides an interventional delivery device, including a support base 1. A limiting rod 2 is inserted into the interior of the support base 1. A fixed base 3 is slidably connected inside the support base 1. A docking hole is formed inside the fixed base 3, and the fixed base 3 is located near the center of the docking hole. Multiple limiting holes are sequentially formed from top to bottom on one side of the support base 1. A hole is formed near the lower part on one side of the fixed base 3. The limiting holes and the hole are of the same size. A spring telescopic rod 4 is fixedly connected inside the fixed base 3. A clamping plate 5 is fixedly connected to one end of the spring telescopic rod 4. A sponge block 501 is clamped inside the clamping plate 5. A main body tube 6 is clamped inside the clamping plate 5. The number of spring telescopic rods 4 is four, and the number of clamping plates 5 and sponge blocks 501 is... The quantity is two. The main tube 6 is located between two sponge blocks 501. A developing ring 7 is fixedly connected to the surface of the main tube 6. The developing ring 7 is embedded in the surface of the main tube 6. The connection between the surface of the developing ring 7 and the surface of the main tube 6 is a smooth transition. A developing hole 8 is fixedly connected to the surface of the main tube 6. One end of the main tube 6 is bent. The shape of the main tube 6 is L-shaped. The developing ring 7 and the developing hole 8 are both located at the bent position on the surface of the main tube 6. A conveying channel 9 is provided inside the main tube 6. A positioning seat 10 is fixedly connected to one side of the fixed seat 3. A positioning rod 11 is inserted into the inside of the positioning seat 10. A disc 12 is rotatably connected to the surface of the fixed seat 3. Multiple positioning holes are opened on the upper surface of the disc 12. The disc 12 is slidably connected to the positioning rod 11 through the positioning holes.

[0037] By squeezing the spring telescopic rod 4, the clamping plate 5 is moved, and the main body tube 6 is placed between the two clamping plates 5. Then, the pressure is released by the spring telescopic rod 4, and the two clamping plates 5 clamp and fix the main body tube 6. By separating the limiting rod 2 from the support base 1 and the fixed base 3, and then sliding the fixed base 3 up and down, the height of the fixed base 3 and the main body tube 6 can be adjusted. After the fixed base 3 and the main body tube 6 are adjusted to a suitable height, the limiting rod 2 is passed through the support base 1 and the fixed base 3 to fix the fixed base 3 and the main body tube 6. By separating the positioning rod 11 from the disc 12, and then rotating the support base 1, when the support base 1 and the main body tube 6 are rotated to a suitable angle, the positioning rod 11 is passed through... The support base 1 and the disc 12 fix the support base 1 and the main tube 6. The imaging ring 7, imaging hole 8 and delivery channel 9 can assist the doctor in delivering the medical device. This reduces the risk of the delivery device being bumped after it has been fixed in the patient's body, which may cause the delivery device to collide with the patient's internal organs and cause discomfort. It also reduces the inability to effectively adjust the position of the delivery device according to the patient's condition or the doctor's surgical habits. This achieves the effect of effectively fixing the delivery device after it has been fixed in the patient's body and effectively adjusting the position of the exposed delivery device according to the patient's condition or the doctor's surgical habits.

[0038] The sponge block 501 can collect the liquid adhering to the surface of the main tube 6 when the doctor removes it from the patient's body. After collection, the sponge block 501 can be separated from the clamp 5, the contaminated sponge block 501 can be discarded, and a new sponge block 501 can be installed inside the clamp 5. This reduces the risk of liquid adhering to the surface of the delivery device when it is removed from the patient's body, and the liquid may drip onto the doctor's hands or the bed, causing contamination. The sponge block 501 can absorb and collect the liquid on the surface of the main tube 6 when it is removed.

[0039] like Figure 7 As shown, a connecting seat 13 is fixedly connected to the lower surface of the disc 12, and a soft pad 14 is fixedly connected to the lower surface of the connecting seat 13. The connecting seat 13 is located near the middle of the lower surface of the disc 12. The soft pad 14 is C-shaped. A fixing strap 15 is fixedly connected to one side of the disc 12. A ventilation hole 16 is opened inside the fixing strap 15. A Velcro face 17 is fixedly connected to the lower surface of the fixing strap 15. A docking strap 18 is fixedly connected to the other side of the disc 12. An air inlet 19 is opened inside the docking strap 18. A Velcro face 20 is fixedly connected to the upper surface of the docking strap 18. The Velcro face 17 and the Velcro face 20 are compatible with each other. There are several ventilation holes 16 and several air inlets 19. The air inlets 19 and the ventilation holes 16 are the same size.

[0040] By placing the soft pad 14 into contact with the patient's arm or leg, tightening the fixing strap 15 and the connecting strap 18 to fit the patient's arm or thigh, and then attaching the Velcro side 17 and the Velcro side 20, the disc 12 is fixed at the arm or leg position where the patient needs to have surgery. Through the vent 16 and the air inlet 19, the patient's restrained position can be ventilated when the fixing strap 15 and the connecting strap 18 are fixed to the patient's arm or leg, reducing patient discomfort. The soft pad 14 can reduce the marks left by the restraints. It also reduces the need for the doctor to hold the delivery device with one hand and connect it to the medical device to be delivered during surgery, which is time-consuming and laborious. This method allows the doctor to place the main tube 6 inside the patient's body and then fix one end of the main tube 6, making it easier for the doctor to pick up the medical device to be delivered and deliver it.

[0041] The working principle of this utility model is as follows: by squeezing the spring telescopic rod 4, the clamping plate 5 is moved, and the main body tube 6 is placed between the two clamping plates 5. Then, the pressure is released by the spring telescopic rod 4, and the two clamping plates 5 clamp and fix the main body tube 6. By separating the limiting rod 2 from the support base 1 and the fixing base 3, and then sliding the fixing base 3 up and down, the height of the fixing base 3 and the main body tube 6 can be adjusted. When the fixing base 3 and the main body tube 6 are adjusted to a suitable height, the limiting rod 2 is passed through the support base 1 and the fixing base 3 to fix the fixing base 3 and the main body tube 6. By separating the positioning rod 11 from the disc 12, and then rotating the support base 1, when the support base 1 and the main body tube 6 are rotated to a suitable angle, the positioning rod 11 is passed through the support base 1 and the disc 12 to fix the support base 1 and the main body tube 6. The imaging ring 7, imaging hole 8, and delivery channel 9 can assist doctors in completing the medical device operation. The procedure involves using a sponge block 501 to collect the liquid adhering to the surface of the main tube 6 when the doctor removes it from the patient's body. After collection, the sponge block 501 can be separated from the sponge plate 5, the contaminated sponge block 501 can be discarded, and a new sponge block 501 can be installed inside the sponge plate 5. The soft pad 14 is brought into contact with the patient's arm or leg, and the fixing strap 15 and the connecting strap 18 are tightened and fitted to the patient's arm or thigh. The Velcro front side 17 and the Velcro back side 20 are then attached to fix the disc 12 in the arm or leg position required for the surgery. The ventilation holes 16 and 19 allow for ventilation of the patient's bound position when the fixing strap 15 and the connecting strap 18 are fixed to the patient's arm or leg, reducing patient discomfort. The soft pad 14 can also reduce chafing marks caused by the binding.

To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0043] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
