Abstract
The invention discloses a magnetic assisted tensioning device for digestive endoscopy surgery, which comprises an in-vitro electromagnet and also comprises an in-vivo branch matched with the in-vitro electromagnet, wherein the in-vivo branch is composed of an in-vivo magnet and micro-surgical forceps which are connected through connecting lines. The tensioning of the focus is completed by utilizing magnetic attraction to achieve the purpose of surgical field exposure. The magnetic assisted tensioning device is especially suitable for lower excision of the gastric mucosa through the digestive endoscopy. By using the device, a tensioning instrument can be used without occupying the operation channel of the digestive endoscopy, the surgical field exposure is still sufficient when the focus is excised, and the focus with the diameter greater than 20mm of the body of the stomach and duodenum can be possibly excised through the digestive endoscopy, thereby expanding the indications of the endoscopy surgery, meeting the requirements of more patients for minimally invasive surgery, and avoiding the wound to a patient due to the laparotomy.
Description
Technical field
The invention belongs to technical field of medical instruments, be specifically related to a kind of magnetic auxiliary pulling device that is used for the digestive endoscopy operation.
Background technology
Minimally Invasive Surgical Technology is the important trend of current surgical field development, and its principle is that the method with small invasion and attack reaches the operative treatment purpose.The digestive endoscopy technology is the important component part of modern less invasive techniques, its digestive tract disease diagnosis and treatment aspect bringing into play more and more important effect, along with deepening continuously that endoscopic technic is understood, utilize digestive endoscopy to undergo surgery treating digestive tract tumor has been that institute of society approves that extensively what wherein relatively give prominence to is the excision under the digestive endoscopy gastric mucosa that is used for the treatment of shallow gastric cancer.Compare with traditional operation, this mode has that wound is little, the patient recovers fast and satisfy aspect such as patient's wound beauty treatment requirement has incomparable advantage.This operation at present at home and abroad some medical centres become the first-selected art formula of shallow curing gastric cancer.
Yet the self-defect of existing digestive endoscopy has limited under the digestive endoscopy gastric mucosa excision and has further applied.When carrying out under the digestive endoscopy gastric mucosa excision at present, finishing the needed various devices of operation all needs enter gastric by operating walk way, and the space of operating walk way is limited, operation when can not satisfy a plurality of operating theater instruments.Therefore in practical operation, just can't use the tractive apparatus when carrying out gastric mucosa under excision, the consequence that causes is, when pathological changes is positioned at body of stomach or the pathological changes area is excessive, when referring generally to its diameter greater than 20mm, because the reason of art open country exposure, this operation can't be carried out.
Summary of the invention
In order to overcome the deficiency that above-mentioned prior art exists, the object of the present invention is to provide a kind of magnetic auxiliary pulling device that is used for the digestive endoscopy operation, finish tractive by utilizing magnetic attracting force to focus, reach the wild purpose that exposes of art, be specially adapted to excision under the gastric mucosa of digestive endoscopy, this device makes the use of tractive apparatus not take the operating walk way of digestive endoscopy, still have the wild exposure of sufficient art when making lesion resection, body of stomach and refer to that diameter becomes possibility greater than the focus of 20mm by the digestive endoscopy excision, enlarge the endoscopic surgery indication, satisfy the demand of more patients, the wound of avoiding abdominal that the patient is caused to Minimally Invasive Surgery.
In order to achieve the above object, the technical solution adopted in the present invention is:
A kind of magnetic auxiliary pulling device that is used for digestive endoscopy operation comprises external electric magnet 1, also have in addition with should be external branch in the suitable body of electric magnet 1, branch is made up of the body internal magnet 3 and the microforceps 5 of connecting line 4 connections in the body.
The mode of the distance of described external electric magnet 1 by regulating itself and body internal magnet 3 changes magnetic force.
Described body internal magnet 3 is made of rubidium ferrum boron magnetic material, and this body internal magnet surface also is coated with nickel block in addition, and this nickel block size is: long 1.0cm, wide 1.0cm, high 1.5cm.
Finish tractive by utilizing magnetic attracting force to focus, reach the wild purpose that exposes of art, be specially adapted to excision under the gastric mucosa of digestive endoscopy, this device makes the use of tractive apparatus not take the operating walk way of digestive endoscopy, still have the wild exposure of sufficient art when making lesion resection, body of stomach and refer to that diameter becomes possibility greater than the focus of 20mm by the digestive endoscopy excision, enlarge the endoscopic surgery indication, satisfy the demand of more patients, the wound of avoiding abdominal that the patient is caused to Minimally Invasive Surgery.
Description of drawings
Fig. 1 is a structural representation of the present invention, and wherein Fig. 1 (a) is external electromagnet structure sketch map, and Fig. 1 (b) is branch's connection diagram in the body.
The specific embodiment
The present invention will be described in more detail below in conjunction with accompanying drawing.
As shown in Figure 1, be used for the magnetic auxiliary pulling device of digestive endoscopy operation, comprise external electric magnet 1, also have in addition with should be external branch in the suitable body of electric magnet 1, branch is made up of the body internal magnet 3 and the microforceps 5 of connecting line 4 connections in the body.The mode of the distance of described external electric magnet 1 by regulating itself and body internal magnet 3 changes magnetic force.Described body internal magnet 3 is made of rubidium ferrum boron magnetic material, and this body internal magnet surface also is coated with nickel block in addition, and this nickel block size is: long 1.0cm, wide 1.0cm, high 1.5cm.
Operation principle of the present invention is: when carrying out the digestive endoscopy operation, after treating that early stage, operation was finished, the interior branch of body that will be used for the magnetic auxiliary pulling device of digestive endoscopy operation puts into gastric by operating walk way, utilize microforceps 5 clamping focus edges earlier, by the magnetic attracting force between body internal magnet 3 and the external electric magnet 1 focus is carried out tractive then, do not taking under the operating walk way prerequisite of digestive endoscopy, finish the abundant exposure of art open country, make body of stomach and refer to that diameter becomes possibility greater than the focus of 20mm by the digestive endoscopy excision thus.
