Patent Application
20200352567
The present application relates to a surgical operation instrument, and particularly relates to a reusable powered endoscopic cutter stapler, used for transection, resection, and anastomoses of lung, stomach and intestinal tissues. The instruments have application in multiple open or minimally invasive surgical procedures.
Along with popularization of minimally invasive surgery, endoscopic cutter staplers have become a kind of conventional surgical instruments. Existing mechanical endoscopic cutter staplers are operated by hand, and have the deficiencies of being unstable in cutting, weak in firing force, low in reliability, strenuous in operation and the like, that may cause unnecessary pain or trauma to patients in a treatment process, and also will bring hidden danger in health to the hand joints of doctors using the endoscopic cutter staplers for a long times. In recent years, disposable powered endoscopic cutter staplers appearing on the market may solve the above-mentioned problems, but the disposable powered endoscopic cutter staplers often bring economic burden for patients due to high cost and high price.
Currently, some reusable powered endoscopic cutter staplers also appear on the market, which reduces the cost of patient in treatment by using instruments, however, core components of the staplers are not suitable for being sterilized repeatedly and are only isolated from patients by a physical device in use and simply wiped after being used, to avoid cross infection. Therefore, when being treated by using instruments, great risk of cross infection is caused to the patient. Moreover, due to a motor and a battery pack inside, such kind of powered endoscopic cutter stapler is heavy in overall mass and brings inconvenience for doctors in operation.
In order to solve the foregoing technical problems, the present application provides a powered endoscopic cutter stapler which can be sterilized repeatedly, the stapler can be reused for many times after being sterilized, and thus solves the technical problem that powered staplers existing in the prior art cannot be sterilized repeatedly, and by unique product design, the overall mass of the stapler is lightened, and convenience for operation by doctors is improved.
According to an aspect of the present application, a reusable powered endoscopic cutter stapler is provided, which is used for transection, resection, and anastomoses of lung, stomach and intestinal tissues in multiple op en or minimally invasive surgical procedures. And can be sterilized repeatedly and used for many times. The powered stapler which can be sterilized repeatedly includes: a controller, a handle, an adapter and a cable component; the adapter being connected with the handle; one end of the cable component can be detachably connected with the controller, the other end being detachably connected with the handle to be used for transmitting electric energy and command signals; the controller can be reused for many times, and the cable component can be reused for many times after being sterilized.
In a first implementation mode, the adapter is detachably connected with the handle; the adapter being a disposable, component and the handle can be reused for many times after being sterilized.
In a second implementation mode, the adapter and the handle combine a whole device, the whole device being reused for many times after being sterilized.
In a third implementation mode, the adapter and the handle combine a whole device, the whole device being a disposable component.
In a fourth implementation mode, the controller includes a battery pack and a control module which are detachably connected, electric energy of the controller can be supplied by the battery pack, the battery pack and the adapter being disposable components, and the handle can be reused for many times after being sterilized.
According to another aspect of the present application, a reusable powered endoscopic cutter stapler is provided, which is used for transection, resection, and anastomoses of lung, stomach and intestinal tissues in multiple open or minimally invasive surgical procedures and can be sterilized repeatedly and used for many times. The powered stapler which can be sterilized repeatedly includes a controller, a handle and an adapter; the adapter being connected with the handle; the controller can be directly mounted on the handle and detachably connected with the handle, the controller including a battery pack and a control module, electric energy of the controller can be supplied by the battery pack, the adapter and the battery pack being disposable components, and the handle can be reused for may times after being sterilized.
Further, the controller includes a battery pack and a control module, the battery pack converting power frequency voltage into DC voltage needed by the handle; the control module including a circuit board component and a software program and being in charge of the mechanism operation and indication of the handle.
Further, the handle acquires electric energy from the controller and operates and indicates the adapter according to the instruction of the controller, including firing or withdrawing a blade, and indicating the location and direction as well as residual use times of a handle.
Further, the handle includes a handle shell, a firing handle, a safety trigger, a return button, a stroke indicator light, a residual use time indicator light and a direction indicator light.
Further, the adapter includes an outer tube, a rotation collar and a rotation knob; the far end of the outer tube being loaded with a proper cartridge in use to be used for anastomosis.
According to the reusable powered endoscopic cutter stapler disclosed by the present application, at least one or multiple components of a core component can be sterilized repeatedly, and can be used for many times, thereby not only greatly lowering the treatment expense of patients, but also greatly reducing the risk of cross infection when instruments are used by setting a component for contacting human tissues to a working terminal as a disposable component or independently sterilizing the component at the working terminal, improving the use safety and reliability of the instruments, and greatly lightening the overall mass, so that a doctor can operate more conveniently. Moreover, a detachable battery pack is used for supplying energy for the controller, so that the stapler is not limited by use occasions, and portability is improved.
The following clearly and completely describes the technical schemes in the embodiments of the present invention. Apparently, the described embodiments are some of the embodiments of the present invention rather than all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present disclosure.
For the convenience of description, “near end” in the present disclosure refers to an end close to an operator after the operator holds an instrument, and “far end” refers to an end far away from an operator after the operator holds the instrument.
