Abstract
The invention relates to a magnetic auxiliary tensioning device for a single-pore laparoscope. The magnetic auxiliary tensioning device for the single-pore laparoscope comprises an abdominal wall outer electromagnet capable of adjusting a magnetic force and an abdominal wall inner electromagnet matched with the abdominal wall outer electromagnet, a semicircular ring is connected to the bottom of the abdominal wall inner electromagnet; a pull wire passes through the semicircular ring; and one end of the pull wire is connected with a nonmagnetic titanium alloy forceps clip. When a single-pore laparoscopic surgery is performed, the pull wire can pass through the semicircular ring and an abdominal cavity notch to be controlled in vitro, and a performer indirectly controls and pulls the gall bladder through the pull wire, so by the method, the crowded state of single-pore instruments is improved by using the pull wire; and the pull power is controlled by the performer, so flexibility of the surgery is improved; and the pull direction is adjusted by moving the abdominal wall outer electromagnet to change the position of the abdominal wall inner electromagnet and the pull wire can be pulled to any directions in the range of 360 degrees, so the magnetic auxiliary tensioning device is flexible to use, without adding additional wounds.
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 single-hole laparoscopic.
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.At present, laparoscopic technique has become first-selected art formula in operations such as cholecystectomy, appendectomy.The requirements at the higher level and the doctor that wound are improved looks based on the patient pursue a minimizing stomach wall stamp mouthful complication purpose; Reduce to stab mouthful number and adopt dexterous manipulation more to become the emphasis direction of minimally invasive surgery doctor work; And developed recently gets up through umbilicus single-hole laparoscopic device be surgeon pursue ultra micro woundization practice result through umbilicus single-hole laparoscopic device punctures the introducing pneumoperitoneum through umbilical opening after; Insert the puncture tube in a plurality of operations of portability duct, through operating duct introducing operating theater instruments and luminaire to accomplish operation technique, specimens from pri is taken out through umbilical opening; All concentrate on the single hole entering owing to need insert the operating theater instruments in abdominal cavity; Can take place between the apparatus to be entangled with each other, to interfere, to hinder, influence image, to pass picture stable, the influence motility that dissection, separation etc. are operated of performing the operation.
For overcoming the above problems; Chinese scholars is to constantly improving through umbilicus single-hole laparoscopic device; Use the minor diameter apparatus that is no more than 5mm more in that simple solution comprises extended type apparatus and peritoneoscope, use bent angle or articulate apparatus and the art, develop flexible scope or have the scope etc. of simple and easy light source right angle adapter.But these methods all can not tackle the problem at its root.At this moment have the scholar to propose to reduce apparatus, utilize that suture is fixed, 2～3mm micropore traction device etc. makes it to pass stomach wall and reach requirement through increasing extra wound, but the thinking of the increase of extra wound and minimally invasive surgery is inconsistent through stabbing mouthful.
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 of single-hole laparoscopic, when carrying out single-hole laparoscopic surgery; Draught line can pass semicircle annulus and mouth is stabbed in external control in the abdominal cavity, and the patient controls the traction gallbladder indirectly through draught line, under this mode; The use of draught line has improved the crowded situation of single hole apparatus, and the strength size of traction is controlled by the patient, has increased the motility of operation; Lead is regulated through the position of moving the outer electric magnet change of stomach wall stomach wall internal magnet; Can be in 360 ° scope any direction traction is used more flexibly, need not to increase extra wound in addition.
In order to achieve the above object, the technical scheme that the present invention adopted is:
A kind of magnetic auxiliary pulling device of single-hole laparoscopic; Comprise the outer electric magnet 1 of the stomach wall that to regulate magnetic force; Also comprise the stomach wall internal magnet 2 suitable in addition with the outer electric magnet of stomach wall 1; The bottom of described stomach wall internal magnet 2 is connected with semicircle annulus 3, and draught line 4 passes semicircle annulus 3, and an end of draught line 4 connects no magnetic titanium alloy clamp 5.
When carrying out single-hole laparoscopic surgery, draught line can pass semicircle annulus 3 and mouth is stabbed in external control in the abdominal cavity, and the patient controls the traction gallbladders indirectly through draught line 4; Under this mode; The use of draught line 4 has improved the crowded situation of single hole apparatus, and the strength size of traction is controlled by the patient, has increased the motility of operation; Lead is regulated through the position of moving the outer electric magnet 1 change stomach wall internal magnet 2 of stomach wall; Can be in 360 ° scope any direction traction is used more flexibly, need not to increase extra wound in addition.
Description of drawings
Fig. 1 is a structural representation of the present invention, and wherein Fig. 1 (a) is the outer electromagnet structure sketch map of stomach wall, and Fig. 1 (b) is the connection sketch map of stomach wall internal magnet, semicircle annulus and draught line.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done more detailed explanation.
As shown in Figure 1; The magnetic auxiliary pulling device of single-hole laparoscopic; Comprise the outer electric magnet 1 of the stomach wall that can regulate magnetic force, also comprise the stomach wall internal magnet 2 suitable with the outer electric magnet of stomach wall 1 in addition, the bottom of described stomach wall internal magnet 2 is connected with semicircle annulus 3; Draught line 4 passes semicircle annulus 3, and an end of draught line 4 connects no magnetic titanium alloy clamp 5.The size that this device is regulated pull strength through hands tractive draught line 4; Be referred to as " marionette " method, can use a plurality of magnetic auxiliary pulling devices in the operation, reach good reservation art wild in; Do not disturb operative space, do not increase extra wound.
Operation principle of the present invention is: in the single-hole laparoscopic surgery, with stomach wall internal magnet 2 and draught line 4 and do not have magnetic titanium alloy clamp 5 usefulness laparoscopic instruments and stab through single hole through stomach wall and mouthful get into an abdominal cavity, the other end of draught line 4 is retained in external; Use laparoscopic procedure apparatus clamping stomach wall internal magnet 2; Be involutory with the outer electric magnet 1 of stomach wall, regulate the outer electric magnet 1 magnetic force size of stomach wall, stomach wall internal magnet 2 is attracted to be fixed on the stomach wall; Use the laparoscopic procedure apparatus will not have magnetic titanium alloy clamp 5 and clamp destination organization; The patient moves the position that the outer electric magnet 1 of stomach wall changes stomach wall internal magnet 2, controls the direction of traction tissue, after operation finishes; Take off no magnetic titanium alloy clamp 5 through the laparoscopic procedure apparatus, at last with stomach wall internal magnet 2, draught line 4 and do not have magnetic titanium alloy clamp 5 and stab through single hole and mouthful take out an abdominal cavity.
