Description

Slave end portion for vascular interventional surgical robot

Technical Field

Background

Minimally invasive vascular intervention is a basic means for diagnosing and treating cardiovascular and cerebrovascular diseases, and most of vascular lesion diagnosis and vascular reconstruction operations carried out at present need to be carried out by the aid of the technology. The operation of guidewires, catheters and balloon catheters is the core of minimally invasive vascular interventional procedures, which determines the quality of the procedure. Currently, interventional physicians manually perform the positioning of a guidewire-catheter within a patient's blood vessel by means of digital silhouette angiography imaging technique (DSA). The guide wire, the catheter and the balloon catheter are basic instruments used in the operation, and the robot is used for positioning the guide wire, the catheter and other medical instruments, so that the accuracy and the stability of the positioning operation are improved, medical staff is released from radiation, the additional injury caused by wearing thick and heavy lead clothing by the medical staff is avoided, the situation that the operation is unreliable in the operation due to tiredness of the medical staff is avoided, the situation that the vascular intervention operation extremely depends on the personal experience of a doctor is improved, the learning curve of the intervention operation is reduced, and more accurate operation is provided for the vascular intervention operation.

The medical catheter is of a hollow tubular structure, and the internal cavity is a contrast agent injection channel or a medical instrument conveying channel. Because the catheter has stronger hardness and is inconvenient to complete vessel selection, a solid guide wire with stronger flexibility is adopted to guide the catheter into a target vessel. During the operation, the doctor performs vascular puncture in the femoral artery or radial artery and leaves a vascular sheath as an inlet for the catheter to enter the blood vessel. The catheter is passed through the vascular sheath into the vessel in the patient, and the guidewire is passed from the passageway inside the catheter into the vessel. Control of catheter, guidewire advancement, retraction, and rotation is typically accomplished by the interventional physician with his or her assistant two and four hands.

The conventional vascular interventional operation robot is only provided with a guide catheter, and has a defect that a tube wire cannot be delivered for a long distance due to a single function due to lack of a rotation/delivery function of an intermediate catheter.

In view of the above-described problems with conventional vascular interventional surgical robots, there is a need in the art for surgical robots with further improved performance.

When the front end catheter operation box is installed, the front end catheter operation box is arranged on one side of the robot body, and then the plug-in component is inserted into the plug-in port along the lateral direction, so that the front end catheter operation box is inserted into the robot body.

As a preferred solution, a catheter delivery aid is provided from the end for a vascular interventional surgical robot, the detailed structure of which is described herein below for the sake of disclosure integrity, see the applicant's issued patent CN 217244783U.

As shown in fig. 2, the catheter delivery assisting device includes a mouth gag 81 (see fig. 22 to 24) and a support tube 82 in the form of a C-tube, the front and rear ends of which are fixed to a front end bracket assembly 202 and a rear end bracket assembly 203 of the robot body by a front end fixing device 200 and a rear end fixing device 201, respectively, the specific structure of the front end fixing device 200 and the rear end fixing device 201 is not the subject of the present utility model, and any suitable structure may be adopted, and the description thereof is omitted herein.

Fig. 19, 20 and 21 illustrate a C-tube for a catheter delivery aid, wherein fig. 19 is a perspective view of the C-tube, fig. 20 is a cross-sectional view of the C-tube, and fig. 21 is a plan view of the C-tube after deployment. As shown in fig. 19 and 20, the C-tube is formed with an axially extending slot, the C-tube is an open self-collapsible tube, and is in the form of a closed "O" in its natural state, with the two circumferential ends 85 and 86 of the tube abutting or interfitting; and under the action of the expansion element or in a state that the two circumferential end parts are in tension, the two circumferential end parts are separated from each other to form an opening to form a C shape.

The C-tube can take a variety of forms, the most common one being one in which an axially extending through slot is formed in the complete round tube. Fig. 21 illustrates a preferred embodiment of a C-tube having, in a plan-expanded view, a plurality of intermediate slots 83 disposed centrally and axially spaced apart, and a plurality of edge slots 84 disposed circumferentially on either side and axially spaced apart, the intermediate slots 83 being axially staggered with the edge slots 84, as shown in fig. 21. The C-shaped pipe of the embodiment has better flexibility and extensibility.

In use, the C-shaped tube is secured at both ends to the front and rear ends of the robot body by securing means and is held in an extended state, and preferably in a tensioned state, to support a catheter passing therethrough.

Next, referring to fig. 22 to 25 and fig. 2, the mouth gag provided on the instrument operation cassette 3 and its cooperation with the C-shaped tube will be described first. As shown in fig. 22, 25 and 2, the mouth gag 87 provided on the instrument operation cassette 3 includes a first C-shaped pipe support portion 88, a second C-shaped pipe support portion 89 (see fig. 2 and 25), a catheter support portion 90 and a shuttle-type slide rail 91.

In the opener of the catheter delivery aid of this embodiment, the first C-shaped tube support portion 88, the catheter support portion 90, and the shuttle-type chute 91 are integrally formed.

As shown in fig. 22, the mouth gag includes a main body 98, and a first C-tube support 88 provided at the front of the main body in the form of a tube barrel, with a first C-tube passage 92 through which a C-tube is formed. During operation, the mouth gag and thus the first C-shaped tube passage 92 move back and forth relative to the C-shaped tube, and therefore the C-shaped tube needs to be movably disposed in the first C-shaped tube passage 92. The passage section of the first C-shaped pipe passage is preferably circular, the diameter of which is not particularly limited as long as the relative movement between the first C-shaped pipe passage 92 and the C-shaped pipe and the positioning of the C-shaped pipe in the first C-shaped pipe passage 92 can be achieved, and as a preferable mode, the diameter of the first C-shaped pipe passage 92 is equal to or slightly larger than the diameter of the C-shaped pipe in an extended or tensioned state in use, on the one hand, the positioning of the C-shaped pipe is facilitated, and on the other hand, the passing of the C-shaped pipe from the first C-shaped pipe passage 92 is facilitated.

The conduit support portion 90 is cylindrical in shape and has a rear end fixed to the main body 98 in a longitudinal direction, the conduit support portion 90 being disposed adjacent to the first C-shaped tube support portion 88 and being located longitudinally behind the first C-shaped tube support portion 88, and a conduit passage 93 through which a rear end conduit passes is provided, the conduit passage 93 being opposite to the first C-shaped tube passage 92.

The shuttle-type chute 91 is provided in the duct supporting portion 90, and is connected to a front end portion or a portion near the front end portion of the duct supporting portion, and the shuttle-type chute 91 is inclined laterally rearward with respect to the duct path 93 and extends to the robot body side so that the C-shaped tube is deviated from the path of the rear-end duct. The connecting portion of the shuttle-shaped slide and the catheter support portion that are connected to each other may peel the C-shaped tube apart so that both circumferential ends of the C-shaped tube sandwich the connecting portion therebetween, in other words, the connecting portion separates both circumferential ends of the C-shaped tube.

Referring to fig. 2 and 25, the second C-shaped pipe supporting portion 89 is in the form of a bent pipe, and is disposed at a side rear of the shuttle-type slide rail and at a side of the robot body. The second C-tube support defines a second C-tube passage through which the C-tube passes, including a first tube section 99 and a second tube section 100, the first tube section 99 extending toward the shuttle ramp 91 with its passage opening substantially aligned with the shuttle ramp, the second tube section 100 extending longitudinally rearward. The second C-shaped pipe supporting portion 89 is used for positioning the C-shaped pipe and limiting the trend of the C-shaped pipe. In the illustrated embodiment, the second C-shaped tube passage of the second C-shaped tube support is an obtuse angled passage, and the portions of the passage defined by the first tube section 99 and the second tube section 100 have a smooth transition. In the illustrated embodiment, the second C-shaped tube support 89 includes a first tube segment 99 and a second tube segment 100 in the form of a bent tube, although it should be noted that although this is a preferred embodiment, the second tube segment 100 may be omitted.

In the use state, each component part of the opener is fixedly arranged on the instrument operation box. For this reason, as shown in fig. 23, two screw holes 96 are formed on the bottom surface of the opener main body 98; in contrast, as shown in fig. 24, two screw holes 97 are formed in the mounting surface of the instrument operation box, so that the opener main body can be fixed to the instrument operation box by screws. Further, as shown in fig. 22, a locking groove 101 is formed in the bottom surface of the opener main body 98 to be locked to the front end wall 102 of the instrument operation box. The second C-shaped tube support 89 may be secured to the instrument cassette by screws.

Reference is now made to fig. 25 and 26, which illustrate the mounting of the mouth gag on the instrument operation cassette. As shown in fig. 26, the body 98 of the mouth gag is secured to the instrument cassette 37 such that the first C-shaped tube support portion 88, the catheter support portion 90 and the shuttle ramp 91 are secured in place on the instrument cassette along with the mouth gag body 98, with the first C-shaped tube support portion 88 being located in a recess 103 formed in the front wall of the instrument cassette; and the second C-shaped tube support portion 89 is fixed to the instrument operation cassette by screws.

In the assembled state of the catheter delivery aid, referring to fig. 2, 25 and 26, the front and rear ends of the c-shaped tube are secured to the front and rear

end bracket assemblies

202 and 203 of the robot body with front and rear

end securing devices

200 and 201, respectively, and are in an extended or tensioned state. The C-tube extends rearward from the front end of the robot body, passes through the front end catheter cartridge 2 to the front end of the instrument cartridge, passes through the first C-tube channel 92, fits over the shuttle ramp 91, then passes through the second C-tube channel and continues to extend rearward to the rear end of the robot body. The part of the C-shaped pipe, which is positioned at the connecting position where the shuttle-shaped slideway and the catheter supporting part are connected with each other, is peeled off by the connecting position, the part of the C-shaped pipe, which is positioned in front of the outlet of the front end of the catheter channel of the catheter supporting part, is in a closed O-shaped state, and the part of the C-shaped pipe, which is positioned at the longitudinal rear end of the shuttle-shaped slideway, is also in a closed O-shaped state. Further, as shown in fig. 26, the rear end catheter is inserted into the catheter passage of the catheter support section 90 from the rear end, and then is inserted into and supported by the C-shaped tube located at the front of the catheter passage of the catheter support section 90.

The operating principle of the mouth gag of the utility model is as follows.

As shown in fig. 2 and 25, when the instrument operation cassette moves together with the opener in the longitudinal direction indicated by the arrow a or in the opposite direction with respect to the C-shaped tube, the connecting portion of the shuttle-type slide and the catheter supporting portion that are connected to each other peels off the corresponding portion of the C-shaped tube, and as the opener moves, the peeled portion of the C-shaped tube moves in the opposite direction with respect to the opener, and after moving over the connecting portion of the shuttle-type slide and the catheter supporting portion, the C-shaped tube returns to the O-shaped state by its own elasticity. Thus, during operation, the C-tube is always in an extended or tensioned state, the portion of the C-tube located forward of the forward end outlet of the conduit channel of the conduit support being in a closed "O" shape, forming a support tube, and the rear end conduit portion located at that location forming a stable support.

In order to avoid the occurrence of an inner curl in the circumferential edge of the C-tube as it passes over the connecting portion of the shuttle-type chute and the catheter support portion, the connecting portion 94 of the shuttle-type chute to the catheter support portion 90 preferably comprises a length having an outer contour sized such that the C-tube on the portion is stretched by the shuttle-type chute to take a "C" shape with the inner peripheral surface of the C-tube conforming to the outer surface of the shuttle-type chute, as shown in fig. 22. The connecting part can be cylindrical, elliptic cylindrical or other similar shapes, and can be used for expanding the C-shaped pipe to form a C shape and reliably attaching the C-shaped pipe to the inner peripheral surface of the C-shaped pipe.

As a preferred option, the connection point 94 of the shuttle ramp to the catheter support 90 is generally olive-shaped, the olive-shaped portion comprising a length having an outer dimension such that a C-shaped tube positioned over the length is stretched by the shuttle ramp and conforms to the outer surface of the shuttle ramp to assume a "C" shape. The shuttle ramp further comprises tapered portions at both ends, preferably the free ends of the tapered portions having a diameter smaller than the inner diameter of the C-tube in the extended or tensioned state, to guide movement of the mouth gag relative to the C-tube. In addition, in order to facilitate movement of the mouth gag relative to the C-tube, as a preferred embodiment, the end of the mouth gag shuttle slide is rounded.

In order to prevent the C-tube from being laterally offset relative to the shuttle ramp and not being able to properly cooperate with the shuttle ramp, the mouth gag also includes a abutment. Referring to fig. 2, 25 and 26, since the passage opening of the first C-shaped tube passage 92 of the first C-shaped tube supporting portion 88 and the passage opening of the first tube section 99 of the second C-shaped tube supporting portion 89 are not aligned with each other, the connection line of the two and the shuttle-type slide may not coincide, so that the C-shaped tube in the stretched state or the tensioned state tends to be shifted toward the connection line side, and if the shift is too large, the operation of the catheter delivery assisting device is affected. Therefore, as a preferable mode, a blocking portion is provided on the wire side to prevent the C-shaped tube from being deviated. As shown in fig. 25 and 26, in the illustrated embodiment, the abutment 107 is integrally formed with the second C-shaped tube support 89 and is located at the front of the first tube section 99 in the form of an arcuate plate with a longitudinal forward end adjacent the connection point of the shuttle-type slide to the tube support. Alternatively, the abutment may be tubular, formed by an extension of the first tube section 99; alternatively, the abutment may be a separate component which is secured to the instrument pod during use.

The mouth gag provided on the front end catheter operation box 2 and its cooperation with the C-shaped tube will be described below with reference to fig. 14B. As shown in fig. 14B, two

openers

108, 109 are provided on the front catheter operation box 2, the front openers 108 and the rear openers 109 are mirror-symmetrical, and the front openers 108 are identical in structure to the openers 87 provided on the instrument operation box 3, and the description thereof is omitted for the sake of brevity. In the embodiment shown in fig. 14B, the second C-shaped tube support portion 89 of the front mouth gag 108 ^’ Is a second pipe segment 100 of (1) ^’ Is connected to the second tube segment 100 "of the second C-shaped tube support portion 89" of the rear mouth gag 109 to form an integral structure. The working principle of the front and

rear openers

108, 109 is identical to that of the openers 87 provided on the instrument operation box 3, and a detailed description thereof is omitted for the sake of brevity.

In the assembled state of the catheter delivery aid, referring to fig. 2, 14B, 25 and 26, the front and rear ends of the c-shaped tube are secured to the front and rear

end bracket assemblies

202 and 203 of the robot body with the front and rear

200 and 201, respectively, and are in an extended or tensioned state. The C-tube extends rearward from the front end of the robot body, passes through the front and

rear openers

108 and 109 provided on the front end catheter manipulation box 2 to the front end of the instrument manipulation box, then passes through the opener 87 provided on the instrument manipulation box 3, and continues to extend rearward to the rear end of the robot body.

During operation, the C-tube is always in an extended or tensioned state, the portion 209 of the C-tube between the front end of the robot body and the conduit channel front end outlet of the front mouth-piece 108 conduit support (see fig. 2) being in a closed "O" shaped state forming a support tube, providing a stable support for the conduit portion of the front end conduit between the C-tube front end outlet and the conduit channel front end outlet of the front mouth-piece 108 conduit support. The portion 210 (see fig. 2) of the C-tube between the front end outlet of the conduit channel of the conduit support of the mouth gag 87 and the rear end inlet of the conduit channel of the conduit support of the rear mouth gag 109 is in a closed "O" shape, forming a support tube, and the rear end conduit portion at this location forms a stable support. Wherein the rear end duct is led out from the duct channel front end outlet of the duct supporting portion of the mouth gag 87, then enters the duct channel of the duct supporting portion of the rear mouth gag 109, and then enters the front end duct 68 via the Y valve 70 (see fig. 14B, 15 and 16) fixed to the front end duct operation box.
