Problems solved by technology

However, in clinical promotion, the operation ability of the mother magnet is limited, and the use of surgical instruments (graspers, ultrasonic scalpel) still needs manual control outside the body. This is also the limitation that the poking hole of the laparoscopic technique cannot be effectively reduced.

Embodiment Construction

[0035] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples.

[0036] The invention relates to a self-assembled magnetic anchoring device in the body used in laparoscopic cholecystectomy for reducing poking and sticking. Through the self-assembling in the body of sub-magnets, the poking hole can be reduced. In the present invention, self-assembly refers to sending the cylindrical (bar-shaped) sub-magnets into the abdominal cavity by poking them, and using mechanical control to assemble them in the abdominal cavity to form a new frame structure, so as to perform intra-abdominal operations that were difficult to complete before.

[0037] specific reference Figure 1-Figure 12 , The self-assembled magnetic anchoring device in vivo of the present invention mainly includes a permalloy sub-magnet group 1 , a fishing net device 2 , a pull wire group 3 and an in vitro magnet 4 .

[0038] Among them, the permalloy ...

Abstract

The invention provides an in-vivo self-assembly magnetic anchoring device for trocar-reduced laparoscopic cholecystectomy. The in-vivo self-assembly magnetic anchoring device comprises: a permalloy sub-magnet set, which is composed of N permalloy cylinders which are sequentially connected through rotating shafts, wherein the axial direction of the rotating shafts is parallel to the axial directionof the permalloy cylinders, hooks for clamping laparoscopic grasping forceps are arranged at two end parts of each permalloy cylinder; a fishing net unit, which is composed of N-1 nylon threads and anon-magnetic circular ring, wherein one end of each nylon thread is connected to a rotating shaft, and the other end of each nylon thread is fixed to the circular ring; a pull wire set, which is composed of three pull wires and three soft clamps, wherein each soft clamp is connected to the front end of a pull wire, and the tail end of each pull wire penetrates out of a trocar after penetrating through the circular ring; and an in-vitro magnet, which is located in vitro, provides magnetic guidance for self-assembly of the permalloy sub-magnet set, is anchored with the abdominal wall of a self-assembled permalloy sub-magnet set, and adjusts the in-vivo gallbladder to move in different directions through in-vitro manual traction.

Description

technical field [0001] The invention belongs to the technical field of surgical medical instruments, and in particular relates to a self-assembled magnetic anchoring device in the body used for laparoscopic cholecystectomy. Background technique [0002] Since Mouret P of France completed the first laparoscopic cholecystectomy in 1987, laparoscopic technology has been widely used in surgical clinical diagnosis and treatment, and has gradually replaced traditional laparotomy. As a minimally invasive surgery, it uses poking cards to send small lighting and imaging equipment and surgical tools into the abdominal cavity through the abdominal wall to complete the operation. It has the characteristics of small surgical trauma, short time and fast postoperative recovery. [0003] At present, three-hole laparoscopic cholecystectomy is still the most widely used, which requires three holes to be established in the abdominal wall to play the role of observation, main operation and auxi...
