Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a drug-assisted injection device with a pipeline control function and a method of using the same. Background Art

[0002] Minimally invasive interventional therapy is the primary treatment for cardiovascular and cerebrovascular diseases. Guided by fluoroscopic imaging equipment, it utilizes interventional devices to diagnose and treat diseases through physiological cavities. Compared to traditional surgical procedures, it offers significant advantages, including improved efficacy, increased safety, smaller incisions, and shorter postoperative recovery times.

[0003] Vascular interventional procedures primarily include femoral / radial artery puncture, coordinated advancement of a guidewire and angiography catheter, digital subtraction angiography (DSA), coordinated advancement of a therapeutic guidewire and balloon catheter, and stent placement. The coordinated advancement of the guidewire, catheter, and balloon catheter is a time-consuming step in these procedures and requires X-ray image navigation. Currently, vascular interventional procedures are typically performed manually by physicians. During the procedure, DSA emits X-rays, requiring the physician to wear a heavy lead vest. This rapidly degrades the physician's stamina, concentration, and stability, leading to decreased precision and a high risk of life-threatening accidents such as intimal damage and vascular perforation and rupture caused by improper thrust. Furthermore, prolonged wear of the lead vest can damage the physician's spine. Furthermore, the cumulative damage from long-term ionizing radiation exposure significantly increases the physician's risk of leukemia, cancer, and acute cataracts. Therefore, to ensure physician health and surgical quality, research and development of interventional surgical robots is intensifying, and a growing number of robots are now being used in clinical practice.

[0004] When injecting drugs (such as contrast agents, heparin saline or nitroglycerin) during cardiovascular interventional surgery, the doctor needs to inject the drugs into the patient's vascular system through the interventional catheter syringe to perform operations such as vascular imaging. For example, when injecting contrast agents, the existing technology is to assign a separate doctor to perform manual operations, which is not convenient for quantitative injection because the doctor needs to rely on his or her own operating experience to perform stable quantitative injections, and the doctor also needs to cooperate tacitly with the surgeon, which places high demands on the doctor's operation and the doctor will also be exposed to radiation damage during the operation. In addition, before injecting the drug into the pipeline of the interventional device, the blood with air embolism in the pipeline of the interventional device also needs to be sucked out in time, so it is also necessary to switch the manual operation of injecting the drug and sucking out the blood, which is cumbersome. Summary of the Invention

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] Example 1

[0043] Specifically, if Figures 1 to 11 As shown, a drug-assisted injection device with a pipeline control function includes a syringe control module 10220701 and a valve assembly control module 10220702. The syringe control module 10220701 includes a syringe control host 1022070101 and a syringe 1022070102. The syringe control host 1022070101 is provided with a fixed seat 1022070103 and a movable seat 1022070104. The limiting structure of the syringe barrel of the syringe 1022070102 is fixedly arranged on the fixed seat 1022070103, and the limiting structure of the piston handle of the syringe 1022070102 is fixed on the movable seat 1022070104. The piston handle driving mechanism of the syringe control host 1022070101 controls the reciprocating movement of the movable seat 1022070104, thereby controlling the reciprocating movement of the piston handle of the syringe 1022070102. Figure 8 As shown, the fixed seat 1022070103 and the movable seat 1022070104 are provided with a first protruding limiting structure 1022070105;

[0044] The piston handle driving mechanism preferably adopts a combination of a motor and a screw nut structure.

[0045] like Figure 4 As shown, the valve assembly control module 10220702 includes a valve control mechanism 1022070201 and a valve assembly. The valve assembly includes a valve body 1022070202 and a valve control handle 1022070203. The valve body 1022070202 is fixedly arranged on the valve control mechanism 1022070201. The valve control mechanism 1022070201 is provided with a handle rotating seat 1022070204. The power source part of the valve control mechanism 1022070201 drives the handle rotating seat 1022070204 to rotate, and the handle rotating seat 1022070204 drives the corresponding valve control handle 1022070203 to rotate, thereby switching different passages. Figure 4This is a schematic diagram of the state where the rotating isolation sleeve 1060202 is not installed. After the rotating isolation sleeve is installed, the handle rotating seat 1022070204 indirectly drives the valve control handle 1022070203 to rotate through the rotating isolation sleeve 1060202.

[0046] The valve control mechanism 1022070201 is provided with a motor, and the output shaft of the motor drives the corresponding handle rotating seat 1022070204 to rotate through the rotating docking structure.

[0047] The first pipeline 501 and the output channel 207 of the valve assembly are simultaneously connected to the two channels of a valve on the valve assembly. The valve control mechanism drives the control handle of the valve to rotate or translate, thereby controlling the closing and connection of the first pipeline 501 and the output channel 207 of the valve assembly, or the closing and connection of the syringe barrel and the first pipeline 501, or the closing and connection of the syringe barrel and the output channel 207 of the valve assembly.

[0048] like Figure 1 and Figure 2 The valve assembly includes multiple rotary valves, which are connected in series. The valve control mechanism drives the control handles of each rotary valve to rotate. The multiple rotary valves include an output control valve 201 and at least one liquid medicine supply valve. One end of the output channel 207 of the valve assembly is connected to the first output port of the output control valve 201, and the other end of the output channel 207 is connected to the branch of the bifurcation valve on the hand device 101. The syringe 1022070102 can be used to draw blood from the interventional consumables pipeline of the hand device 101 along the output channel 207, or inject different liquid medicines into the interventional consumables pipeline. The second output port of the output control valve 201 is connected to one end of the first pipeline 501.

[0049] The blood in the interventional consumables pipeline is preferably sucked out in the following manner: the end of the first pipeline 501 is connected to the waste liquid collection bag 202, and when the output channel 207 of the valve assembly is connected to the syringe, the blood in the interventional consumables pipeline is drawn into the syringe barrel of the syringe through the syringe; when the first pipeline 501 is connected to the syringe, the syringe discharges the blood in its syringe barrel into the waste liquid collection bag 202 through the first pipeline 501.

[0050] As an alternative solution, the end of the first pipeline 501 is connected to a waste liquid collection bag 202. When the first pipeline 501 is connected to the output channel 207 of the valve assembly, the blood that needs to be discharged from the interventional consumables pipeline is flowed into the waste liquid collection bag through the first pipeline 501 by the pumping function of the heart.

[0051] As an alternative, the second option is: the end of the first pipeline 501 is connected to a first vacuum bottle (not shown in the figure). When the first pipeline 501 is connected to the output channel 207 of the valve assembly, the blood that needs to be discharged from the interventional consumables pipeline can be directly sucked into the first vacuum bottle through the first vacuum bottle.

[0052] The first pipeline 501 is provided with a one-way valve (not shown in the figure), which allows fluid to flow from the valve assembly into the first pipeline, but does not allow fluid to flow from the first pipeline 501 into the valve assembly.

The liquid medicine supply valve includes a first liquid medicine supply valve 203, a second liquid medicine supply valve 204, a third liquid medicine supply valve 205, and a fourth liquid medicine supply valve 206. The third output port of the output control valve 201 is connected to the first output port of the first liquid medicine supply valve 203, and the second output port of the first liquid medicine supply valve 203 is connected to the first liquid medicine supply device. The third output port of the first liquid medicine supply valve 203 is connected to the first output port of the second liquid medicine supply valve 204, and the second liquid medicine supply valve 206 is connected to the first liquid medicine supply device. The second output port of the supply valve 204 is connected to the second liquid medicine supply device, the third output port of the second liquid medicine supply valve 204 is connected to the first output port of the third liquid medicine supply valve 205, the second output port of the third liquid medicine supply valve 205 is connected to the third liquid medicine supply device, the third output port of the third liquid medicine supply valve 205 is connected to the first output port of the fourth liquid medicine supply valve 206, the second output port of the fourth liquid medicine supply valve 206 is connected to the fourth liquid medicine supply device, and the third output port of the fourth liquid medicine supply valve 206 is connected to the output end of the syringe.

[0054] It also includes a bubble sensor, which is arranged on the side of the output channel of the valve component and is used to detect the bubble content in the injection liquid across the output channel of the valve component.

[0055] It also includes a bubble detection isolation component, which includes an isolation membrane and a detection tube. The detection tube includes pipeline connecting parts located at both ends and a detection part located in the middle. The pipeline connecting part of the detection tube extends to the outside of the isolation membrane and is used to be connected to the joint of the valve assembly and the branch of the bifurcated valve in a sterile environment. The detection part of the detection tube extends to the inside of the isolation membrane and is used to place the detection part on the bubble sensor in a sterile environment. The isolation membrane is used to isolate the power source part of the drug injection device.

[0056] like Figure 9, also includes a camera module. The syringe barrel of the syringe is made of transparent material. The camera module includes a camera bracket 301 and a camera 302. The camera bracket 301 extends from the installation plane where the valve assembly is located. The camera 302 is set at the end of the camera bracket 301. The camera 302 is aimed at the valve assembly and the syringe for remotely observing the bubble situation in the syringe.

The rotary isolation sleeve 1060202 is sheathed on the corresponding valve The handle rotating seat 1022070204 of the door control mechanism rotates along with the handle rotating seat, and the valve body 1022070202 is locked and fixed on the valve isolation bottom plate 1060201 through the locking structure, so that the valve control handle 1022070203 of the valve assembly is placed on the corresponding rotating isolation sleeve 1060202. The handle rotating seat of the valve control mechanism indirectly drives the valve control handle 1022070203 to rotate through the rotating isolation sleeve 1060202;

[0058] The locking structure also fixes the valve isolation base plate and the valve control mechanism together. The locking structure is one or a combination of a threaded structure, a snap-fit structure or a lock structure.

[0059] The rotation axis of the rotating isolation sleeve 1060202 is perpendicular to the valve isolation base plate 1060201. The valve isolation base plate 1060201 is provided with multiple rotating isolation sleeves 1060202. The positions of the multiple handle rotating seats 1022070204, the rotating isolation sleeves 1060202, and the valve control handles 1022070203 correspond to each other.

[0060] The syringe clamping isolation assembly 10601 includes a first isolation cover 1060101 and a second isolation cover 1060102 fixedly connected to the isolation membrane 106, and a first pressure cover is connected to the first isolation cover 1060101.

When the limiting structure of the syringe barrel is placed in the first isolation cover 1060101, the first gland 1060103 can press the limiting structure of the syringe barrel into the first isolation cover 1060101 to prevent the syringe barrel from moving. When the limiting structure of the syringe piston handle is placed in the second isolation cover 1060102, the second gland 1060104 can press the limiting structure of the syringe piston handle into the second isolation cover 1060102. Of course, the first isolation cover 1060101 can also be mounted on the movable seat 1022070104, and the second isolation cover 1060102 can be mounted on the fixed seat 1022070103.
