Description
Technical Field
The invention belongs to the technical field of medical surgical instruments, and relates to a sterile isolation cover sheet capable of stretching and retracting and a method.
Background
The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art.
With the development of robotics, the application of robotics is becoming widespread, and vascular intervention robots have been developed. The intravascular interventional robot can replace a doctor to perform intravascular interventional operation beside an operation bed, so that the doctor is prevented from being injured by X rays, and meanwhile, the learning curve of the interventional operation is reduced.
In robotic assisted vascular interventional procedures, a physician performs the task of a surgical procedure with an elongated minimally invasive surgical instrument, requiring that the area adjacent the patient be maintained in sterile conditions. However, the motors, sensors, encoders, electrical connections, etc. that are included in the robotic arm (platform) necessary to control the motion of the surgical instrument are typically not sterilized using conventional methods such as steam, heat, or chemicals, and the robotic arm (platform) is already assembled in place and is not easily sterilized, so that during a surgical procedure, sterile barrier sheets are typically pre-laid on the robotic arm (platform) to isolate them from the surgical instrument.
In the robot system, the sterile isolation cover is generally composed of a cover body and a driving adapter plate, wherein the cover body is made of PE (polyethylene) films into a barrel, one end of the PE films is opened, and then the cover body is covered on the mechanical arm and the operation platform. The driving adapter plate is used for connecting a motor, a detection element and the like on the mechanical arm with the driving box and other instruments through the adapter plate. However, if two or more devices which need to move and stretch relatively are arranged on the mechanical arm (platform), the two driving adapter plates are limited by a single cover body of the sterile isolation cover and cannot move freely.
Disclosure of Invention
In order to solve the problems, the invention provides a sterile isolation cover sheet capable of moving in a telescopic way and a method thereof, and the invention can avoid the contact between the cover body and instruments such as a catheter, a guide wire and the like, thereby avoiding affecting the operation of surgery.
According to some embodiments, the present invention employs the following technical solutions:
a sterile barrier drape for telescopic movement, comprising a drape body, two drive adapter plates arranged on the drape body, and a restraint, wherein:
the driving adapter plates are arranged on the cover body, and a certain distance is reserved between the two driving adapter plates;
a hollow channel is arranged on the cover body between the two driving adapter plates, a constraint piece is arranged in the hollow channel, and two ends of the constraint piece extend to different driving adapter plates respectively to provide constraint force for opposite or opposite movement of the driving adapter plates.
In the technical scheme, the constraint piece is arranged by utilizing the cover body between the two driving adapter plates, so that the constraint piece can be stretched when the distance between the two driving adapter plates is increased; when the distance is reduced, the constraint piece contracts, the deformation of the cover body is always limited, the cover body is orderly deformed when contracted, and the cover body is prevented from being contacted with instruments such as a catheter, a guide wire and the like, so that the operation of an operation is prevented from being influenced.
As an alternative embodiment, the distance between the positions of the cover body where the two driving adapter plates are mounted is greater than or equal to the maximum distance between the two driving adapter plates.
In this way, a certain redundancy of the distance between the cover body and the two driving adapter plates relative to the two driving adapter plates can be ensured.
Alternatively, the restraining member is a spring.
Further, a plurality of fixing points are arranged in the hollow channel, and the spring is fixed in the hollow channel in a segmented mode.
Further, a fixing piece is arranged at the fixing point.
Alternatively, the restraining member is an elastic cord.
Further, the elastic rope is made of silica gel.
As an alternative embodiment, the hollow channels are plural and are respectively arranged on the cover body between the two driving adapter plates in parallel.
Alternatively, the hollow channel is disposed on the inner side or edge of the cover.
Alternatively, the cover body is bonded to the drive adapter plate.
As an alternative embodiment, the expansion ratio of the constraint member can meet the requirement of the distance change between the two driving adapter plates.
The working method of the aseptic isolation cover sheet capable of moving in a telescopic manner comprises the following steps:
when the two driving adapter plates move oppositely and the relative distance increases, the restraint piece stretches to limit the unfolding deformation of the cover body;
when the two driving adapter plates move in opposite directions and the relative distance is reduced, the restraint piece contracts to limit the contraction deformation of the cover body.
Compared with the prior art, the invention has the beneficial effects that:
according to the invention, when the distance between the two driving adapter plates is increased, the elastic rope is stretched; as the distance decreases, the constraint contracts. Because the cover body of the sterile isolation cover is always constrained by the constraint piece, the constraint piece limits the deformation of the cover body, so that the cover body is orderly deformed when contracted, the cover body is prevented from being contacted with instruments such as a catheter, a guide wire and the like, and the operation of an operation is prevented from being influenced.
The invention solves the problem that the cover body needs to move when the adapter plate is driven to move relatively on the sterile isolation cover sheet. Meanwhile, a restraint piece is adopted for the movement of the cover body between the two driving adapter plates, so that the cover body is in a restrained state during telescopic movement, and interference to instruments such as a catheter, a guide wire and the like is avoided.

Detailed Description
The invention will be further described with reference to the drawings and examples.
It should be noted that the following detailed description is illustrative and is intended to provide further explanation of the invention. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.
It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of exemplary embodiments according to the present invention. As used herein, the singular is also intended to include the plural unless the context clearly indicates otherwise, and furthermore, it is to be understood that the terms "comprises" and/or "comprising" when used in this specification are taken to specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof.
As described in the background, in vascular interventional procedures, instruments such as catheters and guidewires are required to be mounted on a mechanical arm (platform) for operation. And the guide wire can do linear motion under the action of the driving mechanism, so that the guide wire and the guide wire can advance and retreat in the blood vessel. In certain instances, there will be relative movement between the catheter and the guidewire, and between the catheter and the catheter. At this time, it is necessary that the sterile barrier single housing portion between the two relative motion assemblies be reciprocally telescoping. Meanwhile, the main instruments used in the vascular interventional operation process are long and thin flexible catheters and guide wires, and the normal work of the catheters and the guide wires cannot be affected by the telescopic deformation of the cover body.
The present invention provides an apparatus to solve the above-mentioned problems.
The following description is made in terms of various embodiments.
Example 1
As shown in fig. 1, a sterile isolation cover sheet includes a cover body, two driving adapter plates disposed on the cover body, and a restraint member disposed on or on the inner side of the cover body between the two driving adapter plates (the restraint member is shown on the upper surface of the cover body for the sake of understanding by those skilled in the art, and is merely illustrative).
In this embodiment, as shown in fig. 2 and 3, the constraining member is a rubber elastic rope, a channel is prefabricated on the cover body of the cover sheet, the elastic rope is placed in the channel, and two ends of the elastic rope are fixed on the cover body near the driving adapter plate. When the distance between the two driving adapter plates is increased, the elastic rope is stretched; when the distance decreases, the bungee cord contracts.
In order to realize the free movement of the sterile isolation cover single cover body along with the driving adapter plates, the size of the cover body between the two driving adapter plates is lengthened, the requirement of the change of the distance between the driving adapter plates during the relative movement is fully met, the cover body between the two driving adapter plates is larger than or equal to the maximum distance between the two driving adapter plates, and the maximum distance between the two driving adapter plates is larger than the initial distance between the two driving adapter plates.
Because the size of the cover body between the two driving adapter plates is far larger than the initial distance between the two driving adapter plates, when the relative distance between the two driving adapter plates is reduced, the cover body is contracted. At this time, the volume of the cover changes, and the cover deforms irregularly, and the volume increases. Because the main instruments used in the vascular interventional operation process are long and thin flexible catheters and guide wires, the normal operation of the catheters and the guide wires can be influenced by the deformation and the volume increase of the cover body, and the risks are brought to the operation. Therefore, the cover body needs to be added with a restraint device, so that the deformation of the cover body during movement is within a controllable range, and the catheter and the guide wire are prevented from being interfered by the cover body.
The constraint piece is skillfully added in the embodiment, and the cover body of the sterile isolation cover is always constrained by the elastic rope, so that the elastic rope is just like a binding belt, the deformation of the cover body is limited, the cover body is orderly deformed when contracted, the cover body is prevented from being contacted with instruments such as a catheter and a guide wire, and the operation of an operation is prevented from being influenced.
Of course, in some embodiments, to achieve good restraint results, this may be achieved by providing multiple strands of bungee cords.
According to the use condition, the size of the cover body is determined, after the size of the cover body is determined, the cover body is unfolded, and the elastic rope expansion channel is manufactured on the inner side surface of the cover body, or the cover body and the cover body are adhered by the sheet PE film made of the same material as the cover body, and the formed cavity channel is the elastic rope expansion channel.
The elastic rope is led into the cavity from one end of the cavity, stretched out from the other side of the cavity, and then two sides of the elastic rope are adhered and fixed on the cover body. At this time, under the constraint of the cavity and the elastic rope, the cover body stretches and deforms along with the stretching of the elastic rope. And finally, adhering and fixing the cover body and the driving adapter plate.
The embodiment solves the problem that the cover body needs to move when the adapter plate is driven to move relatively on the sterile isolation cover sheet. Meanwhile, a restraint device is adopted for the movement of the cover body between the two driving adapter plates, so that the cover body is in a restrained state during telescopic movement, the movement deformation of the cover body is controllable, the interference to instruments such as a catheter and a guide wire is avoided, and the risk of operation is reduced.
Example two
The difference between this embodiment and the above-described embodiment is mainly that:
as shown in fig. 4 and 5, the restraining member is a flat steel wire of a high-elastic spring, and the steel wire (the cross-sectional dimension of the steel wire in this embodiment is 1×0.3mm) is made into a wave shape. And prefabricating a channel on a cover body of the cover sheet, placing the steel wire in a stretched state in the channel, bonding and fixing the steel wire and the cover body at certain intervals, and fixing two ends of the steel wire on the cover body near the driving adapter plate. When the distance between the two driving adapter plates is increased, the steel wire stretches and extends; when the distance decreases, the wire contracts. Because the cover body of the sterile isolation cover sheet is always constrained by the steel wires, the deformation of the cover body is limited, so that the cover body is orderly deformed when contracted, the cover body is prevented from being contacted with instruments such as a catheter, a guide wire and the like, and the operation of an operation is prevented from being influenced.
Also, to achieve good restraining effect, in some embodiments, the method may be implemented by providing a plurality of steel wires.
As shown in fig. 6 and 7, the size of the cover is determined according to the use condition, and after the size of the cover is determined, the cover is unfolded, and the steel wires are adhered and fixed on the inner side of the isolation cover sheet. The two ends of the steel wire are fixed near the two driving adapter plates, and the steel wire and the cover body are bonded and fixed at intervals of a distance (such as 5 cm), and the steel wire is in a stretching state. After the steel wire is fixed, a steel wire expansion channel is manufactured on the inner side surface of the cover body, the steel wire expansion channel can be adhered to the cover body by a sheet PE film made of the same material as the cover body, and the formed cavity channel is the expansion channel of the steel wire. At this time, under the constraint of the cavity and the elastic rope, the cover body stretches and deforms along with the stretching of the elastic rope. And finally, adhering and fixing the cover body and the driving adapter plate.
The data of the above embodiments are only examples and may be altered in other embodiments.
In addition, the above connection method may be replaced by other conventional connection methods in other embodiments. Such as sewing, detachable connections, etc.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
