Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a disinfection and isolation membrane assembly and an interventional robot end device. Background Technology

[0002] Minimally invasive interventional therapy is a major treatment method for cardiovascular and cerebrovascular diseases. Guided by fluoroscopic imaging equipment, interventional instruments are used to diagnose and treat diseases through physiological cavities. Compared with traditional surgery, it has significant advantages such as better efficacy, higher safety, smaller incisions, and shorter postoperative recovery time.

[0003] The main steps in vascular interventional surgery include femoral / radial artery puncture, coordinated advancement of the guidewire and angiography catheter, digital subtraction angiography (DSA), coordinated advancement of the treatment guidewire and balloon catheter, and placement of the vascular stent. The coordinated advancement of the guidewire, catheter, and balloon catheter is the most time-consuming step and requires X-ray-guided image navigation. Currently, vascular interventional surgery is usually performed manually by a surgeon. During the procedure, because DSA emits X-rays, the surgeon needs to wear a heavy lead apron, which leads to a rapid decline in physical strength, reduced attention, and decreased stability, resulting in decreased operational precision and an increased risk of accidents such as endothelial damage, vascular perforation, and rupture due to improper pushing force, endangering the patient's life. Furthermore, long-term wearing of lead aprons can damage the surgeon's spine. Secondly, the cumulative damage from long-term ionizing radiation significantly increases the surgeon's risk of leukemia, cancer, and acute cataracts. Therefore, to protect the health of surgeons and ensure surgical quality, research and development of interventional surgical robots are increasing, and more and more robots are being used clinically.

[0004] During surgical procedures using interventional robots, aseptic requirements necessitate separating sterile and contaminated areas using sterile bags. For example, the sterile environment of the surgical functional module must be isolated from the sterile environment within the linear track assembly. Because the surgical functional module and linear track assembly are close to the patient during surgery, they are susceptible to contamination or adverse effects; therefore, the sterile bags must be replaced before each procedure. Currently, most existing sterile bags are designed for single-track interventional robots; there are no sterile bags available for multi-track interventional robots. Summary of the Invention

[0040] A disinfection isolation membrane assembly includes an isolation membrane for isolating the sterile environment of a surgical functional module from the sterile environment within a linear track assembly. The isolation membrane includes a first isolation membrane and a second isolation membrane. The first isolation membrane is sleeved on the outside of the linear track assembly, and the second isolation membrane covers the first isolation membrane. There is a partial overlap between the first isolation membrane and the second isolation membrane.

[0041] The first isolation membrane has a long, strip-shaped slot on one side that is parallel to the linear track assembly. The width of the slot is 100-300mm. The length of the first isolation membrane is adapted to the length of the linear track assembly, and the length of the first isolation membrane exceeds 1200mm.

[0042] The second isolation membrane is elongated and covers the slot parallel to the linear track assembly. The width of the second isolation membrane is 150-350mm. The connection structure between the second isolation membrane and the first isolation membrane or the linear track assembly is one or a combination of hook structure, adhesive structure, magnetic structure, and snap-on structure.

[0043] When the connection structure is a hook structure, hooks or holes are provided at the front and rear ends of the first isolation membrane or linear track assembly, and holes or hooks are provided on the second isolation membrane at positions corresponding to the hooks or holes. The hooks pass through the holes to achieve the fixed installation of the second isolation membrane.

[0044] The upper half of the second isolation membrane overlaps with the upper half of the groove of the first isolation membrane, and the lower half of the second isolation membrane overlaps with the lower half of the groove of the first isolation membrane. The upper half of the groove of the first isolation membrane covers the outside of the upper half of the second isolation membrane, and the lower half of the second isolation membrane covers the outside of the lower half of the groove of the first isolation membrane.

[0045] The first isolation membrane has a first pocket-shaped isolation portion on its upper side, which protrudes from the upper side of the first isolation membrane to form a first cavity; the first isolation membrane has a second pocket-shaped isolation portion on its lower side, which protrudes from the lower side of the first isolation membrane to form a second cavity.

[0046] The first pocket-shaped isolation part is provided with a detection tube segment. The two ends of the detection tube segment are located outside the first pocket-shaped isolation part, and the middle part of the detection tube segment is located inside the first pocket-shaped isolation part. The part of the detection tube segment that passes through the first pocket-shaped isolation part is sealed to ensure the seal between the detection tube segment and the first pocket-shaped isolation part.

[0047] Specifically, such as Figures 1-4 As shown, it includes a first isolation membrane 1 and a second isolation membrane 2. The first isolation membrane 1 is sleeved on the outside of the linear track group 3. The two linear track groups 3 are the first linear track group and the second linear track group, respectively. The second linear track group is located above the first linear track group. The second isolation membrane 2 covers the first isolation membrane 1. The upper half of the second isolation membrane overlaps with the upper half of the groove of the first isolation membrane, and the lower half of the second isolation membrane overlaps with the lower half of the groove of the first isolation membrane.

[0048] The first isolation membrane 1 has a long, strip-shaped slot on one side that is parallel to the linear track group 3. The slot allows the fixing seats of each module on the first and second linear track groups to extend out from the first isolation membrane 1.

[0049] The second isolation membrane 2 is elongated and parallel to the linear track group 3, covering the first and second linear track groups. The connection structure between the second isolation membrane 2 and the first isolation membrane 1 or the linear track group 3 is one or a combination of hook structure, adhesive structure, magnetic structure, and snap-on structure. When the connection structure is a hook structure, hooks 101 or holes are provided at the front and rear ends of the first isolation membrane 1 or the linear track group 3, and holes 201 or hooks are provided on the second isolation membrane 2 at positions corresponding to the hooks 101 or holes. The hooks pass through the holes to fix the second isolation membrane, thus fixing the second isolation membrane 2 to the first isolation membrane 1. The second isolation membrane 2 can also be completely straightened so that the surgical functional modules will not be scraped by the second isolation membrane 2 when they move axially.

[0050] Before surgery, the linear track assembly 3 needs to be covered with the first isolation membrane 1 and the second isolation membrane 2. The first isolation membrane 1 covers the upper drug injection module at the same time as the linear track assembly 3 is covered. Before covering the first isolation membrane 1 and the second isolation membrane 2, the sterile shell 4 of the module fixing seat used to install each surgical function module (including the first port control mechanism 10271, the second port control mechanism 10273, the first rotary delivery mechanism 10272, the second delivery mechanism 10274101, the third rotary delivery mechanism 10276 and the first port support mechanism 1027601) needs to be installed to prevent the first isolation membrane 1 and the second isolation membrane 2 from being contaminated by the sterile mechanism.

[0051] In order to enable the second isolation membrane 2 to be embedded in the upper half of the groove of the first isolation membrane 1, a tear and an adhesive layer are provided on the side of the first isolation membrane 1 at the location of the hook 101. After tearing open the tear of the first isolation membrane 1, the second isolation membrane 2 is embedded in the upper half of the groove of the first isolation membrane 1, and then the tear is pasted onto the second isolation membrane 2 with the adhesive layer located at the tear to achieve good isolation.

[0052] like Figure 5 As shown, the sterile housing 4 has a bottom plate 401 that can be rotated open or detachably opened. During installation, the bottom plate 401 is opened, and the sterile housing 4 is placed on the module fixing seat from top to bottom. Then, the bottom plate 401 is closed and locked, which can isolate the sterile environment of each module fixing seat from the sterile environment during surgery. The sterile housing 4 is provided with several transmission structures, which transmit the power inside the module fixing seat to the sterile port control mechanism and / or rotary delivery mechanism.

[0053] The upper half of the second isolation membrane 2 overlaps with the upper half of the groove of the first isolation membrane 1. Each module fixing seat on the second linear track group is provided with a recess. The upper half of the groove of the first isolation membrane 1 is embedded in the recess. The upper half of the second isolation membrane 2 is embedded in the gap between the module fixing seat on the second linear track group and the outer shell of the second linear track group.

[0054] The lower half of the second isolation membrane 2 overlaps with the lower half of the groove of the first isolation membrane 1. A recess is provided on the module fixing seat on the first linear track group. The lower half of the second isolation membrane 2 is embedded in the recess. The lower half of the groove of the first isolation membrane 1 is embedded in the gap between the module fixing seat on the first linear track group and the outer shell of the first linear track group.

[0055] The first isolation membrane 1 has a first pocket-shaped isolation portion 106 on its upper side. The first pocket-shaped isolation portion 106 protrudes from the upper side of the first isolation membrane to form a first cavity. The first pocket-shaped isolation portion 106 is used to cover and isolate the power source part of the drug injection module. The first isolation membrane has a second pocket-shaped isolation portion 107 on its lower side. The second pocket-shaped isolation portion protrudes from the lower side of the first isolation membrane to form a second cavity. The second pocket-shaped isolation portion 107 is used to cover and isolate the power source part of the pressure injection module.

[0056] Example 2

[0057] like Figure 1As shown, an interventional robot slave device includes a linear track assembly and a disinfection isolation membrane assembly. Two linear track assemblies are arranged in parallel, namely a first linear track assembly and a second linear track assembly. The second linear track assembly is located above the first linear track assembly. Each linear track assembly has at least two module mounting seats arranged sequentially along its length. Surgical function modules are mounted on the module mounting seats. The module mounting seats are fixed to the linear track assemblies, or they can reciprocate on the linear track assemblies. During reciprocating motion, the module mounting seats can drive the corresponding surgical function modules to reciprocate, thereby delivering interventional consumables. A first isolation membrane is fitted over the outside of the linear track assembly. The first linear track assembly and the second linear track assembly... Each module mounting base on the linear track assembly extends from the slot of the first isolation membrane. The second isolation membrane is parallel to the linear track assembly and covers both the first and second linear track assemblies. Each module mounting base on the second linear track assembly has a second recess. The upper half of the slot of the first isolation membrane is embedded in the second recess. The upper half of the second isolation membrane is embedded in the gap between the module mounting base on the second linear track assembly and the outer shell of the second linear track assembly. Each module mounting base on the first linear track assembly has a first recess. The lower half of the second isolation membrane is embedded in the first recess. The lower half of the slot of the first isolation membrane is embedded in the gap between the module mounting base on the first linear track assembly and the outer shell of the first linear track assembly.

[0058] The upper part of the linear track assembly is equipped with a drug injection module for contrast agents or heparin saline. The upper side of the first isolation membrane is provided with a first pocket-shaped isolation part 106, which is used to cover and isolate the power source part of the drug injection module. The drug injection module is equipped with a bubble sensor. The first pocket-shaped isolation part 106 is covered outside the bubble sensor. The bubble sensor is clamped on the outer side of the middle part of the detection tube section.

[0059] like Figures 6-8 As shown, the drug injection module also includes a bubble vibration mechanism that can vibrate the bubbles in the first syringe. The bubble vibration mechanism is an ultrasonic vibrator 108, which is fixed on the first syringe control host. The ultrasonic vibrator 108 is connected to the body of the first syringe through an ultrasonic wave conductor, and the ultrasonic vibrator 108 drives the body of the first syringe to vibrate.

[0060] The ultrasonic wave conductor is a vibration clamping isolation assembly installed on the first pocket-shaped isolation part 106. The vibration clamping isolation assembly includes a clamp seat 10802 fixedly connected to the first pocket-shaped isolation part, and a clamp 10801 connected to the clamp seat 10802. The clamp seat 10802 is fixedly connected to the ultrasonic vibrator 108 through a quick-release structure. The clamp seat 10802 and the clamp 10801 form a clamping groove that is adapted to the shape of the body of the first syringe. When the body of the first syringe is placed on the clamping groove, the clamp 10801 can press the body of the first syringe onto the clamp seat 10802, so that the ultrasonic waves can be smoothly transmitted from the ultrasonic vibrator 108 to the body of the first syringe.

[0061] The drug injection module also includes a bubble sensor 109 capable of detecting the bubble content in the injected liquid. The bubble sensor 109 is fixed on the valve control host and located on the lower side of the first pocket-shaped isolation section.

[0062] The first pocket-shaped isolation section 106 is also equipped with a bubble detection isolation component. The bubble detection isolation component includes a detection tube 10901 fixedly connected to the first pocket-shaped isolation section. The detection tube includes pipe connection sections 1090101 at both ends and a detection section 1090102 in the middle. The pipe connection sections of the detection tube extend to the outside of the first pocket-shaped isolation section. In a sterile environment, they are used to connect to the connector of the valve body and the branch of the bifurcation valve. The detection section of the detection tube extends to the inside of the first pocket-shaped isolation section. In a sterile environment, it is used to be placed on the bubble sensor 109. The bubble sensor 109 detects the content of fluid bubbles inside the detection tube through the tube wall.

The lower side of the first isolation membrane is provided with a second pocket-shaped isolation part 107, which is used to cover and isolate the power source part of the pressurization injection module.

The power source of the second syringe control host 10220801 controls the reciprocating movement of the second movable seat 10220804, thereby controlling the reciprocating movement of the piston rod of the second syringe 10220802. The second fixed seat 10220803 and the second movable seat 10220804 are provided with a second protruding limiting structure 10220805.

[0066] The second pocket-shaped isolation part 107 is equipped with a second syringe clamping isolation assembly 10701. The second syringe clamping isolation assembly 10701 includes a third isolation cover 1070101 and a fourth isolation cover 1070102 fixedly connected to the first isolation membrane 1. A third pressure cap 1070103 is connected to the third isolation cover 1070101, and a fourth pressure cap 1070104 is connected to the fourth isolation cover 1070102. The third isolation cover 1070101 is fitted onto the second fixed seat 10220803, and the fourth isolation cover 1070102 is fitted onto the second movable seat 10220803. 4. When the limiting structure of the body of the second syringe 10220802 is placed inside the third isolation cover 1070101, the third pressure cover 1070103 can press the limiting structure of the body of the second syringe 10220802 inside the third isolation cover 1070101 to prevent the second syringe 10220802 from moving. When the limiting structure of the piston rod of the second syringe 10220802 is placed inside the fourth isolation cover 1070102, the fourth pressure cover 1070104 can press the limiting structure of the piston rod of the second syringe 10220802 inside the fourth isolation cover 1070102.

[0067] The third isolation cover 1070101 and the fourth isolation cover 1070102 are respectively provided with a second housing limiting structure 1070105 in a protruding shape. The inner surface of the second housing limiting structure 1070105 is adapted to the shape of the second protruding limiting structure 10220805 of the second fixed seat 10220803 and the second movable seat 10220804, respectively. The outer surface of the protruding second housing limiting structure 1070105 is adapted to the shape of the limiting structure on the body of the second syringe 10220802 and the piston rod of the second syringe 10220802, respectively.
