Problems solved by technology

But none of these methods can fundamentally solve the problem
At this time, some scholars proposed to reduce the number of instruments passing through the poking opening, and use suture fixation, 2-3mm microporous traction instruments, etc. to meet the requirements by adding additional wounds to pass through the abdominal wall. does not match

Embodiment Construction

[0009] The present invention will be described in more detail below in conjunction with the accompanying drawings.

[0010] Such as figure 1 As shown, the magnetically assisted pulling device for single-port laparoscopy includes an external electromagnet 1 capable of adjusting the magnetic force, and an internal abdominal magnet 2 that is compatible with the external electromagnet 1. The bottom of the internal abdominal magnet 2 is A semicircular ring 3 is connected, a pulling wire 4 passes through the semicircular ring 3 , and one end of the pulling wire 4 is connected with a non-magnetic titanium alloy clamp 5 . The device adjusts the magnitude of the traction force by pulling the traction wire 4 by hand, which is called the "marionette" method. Multiple magnetic auxiliary traction devices can be used in one operation. Interfering with the operating space without additional wounds.

[0011] The working principle of the present invention is: in the single-hole laparoscopic ...

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 [0001] The invention belongs to the technical field of medical instruments, and in particular relates to a magnetic auxiliary pulling device for a single-port laparoscope. Background technique [0002] Minimally invasive surgical technology is an important trend in the development of today's surgical field, and its principle is to achieve the purpose of surgical treatment with a minimally invasive method. At present, laparoscopic technique has become the preferred operation method in cholecystectomy, appendectomy and other operations. Based on patients' higher requirements for wound beauty and doctors' pursuit of reducing the complications of abdominal wall incisions, reducing the number of incisions and adopting more dexterous operations have become the focus of minimally invasive surgeons. The device is the result of surgeons' pursuit of ultra-minimally invasive practice. After the transumbilical single-port laparoscopic device is introduced into the pneum...
