Single-port laparoscopic surgery sheath

Abstract

The invention relates to a medical apparatus, in particular to a single-port laparoscopic surgery sheath, aiming at overcoming the defects that apparatuses are difficult to swing and the apparatuses interfere with each other when the traditional single-port laparoscopic surgery sheath is used. The single-port laparoscopic surgery sheath consists of a supporting sheath, a fixing sleeve and an elastic guide wire. The supporting sheath is divided into an in-vitro section and an abdominal wall section. The single-port laparoscopic surgery sheath is characterized in that a central plate is arranged at the narrowest position of the middle part of the abdominal wall section, apparatus passages are arranged on the central plate, the apparatus passages can swing under the supporting effect of the central plate, and the fixed sleeve and the elastic guide wire are used for fixing the supporting sheath on an abdominal wall. The single-port laparoscopic surgery sheath has the beneficial effects that apparatus fulcrums can be provided at the narrowest position of the surgery sheath, a larger space can be provided for the apparatuses to swing, the collision interference of the apparatuses is reduced, the operating method of the traditional laparoscope can be simulated by using a pre-bent hard single-port laparoscopic apparatus in a matched way, and the difficulty in surgeries is reduced.

Description

technical field [0001] The invention relates to a medical device, in particular to a surgical sheath used in single-hole laparoscopic surgery. Background technique [0002] Compared with traditional laparoscopic surgery, single-port laparoscopic surgery has fewer incisions and is more beautiful, representing the development direction of minimally invasive surgery. The surgical sheath is one of the instruments for single-hole laparoscopic surgery, that is, only one incision is made in the operation to place a working tube, and the sealing cap of the working tube is used to divide it into multiple holes for placing the instrument. The existing single-hole laparoscopic surgical sheath has the following deficiencies in the operation: 1. The instrument channel tube of the surgical sheath is outside the abdomen, and the support point for making the instrument swing is also outside the abdomen, and the narrowest part of the surgical sheath is located on the abdominal wall. The con...

Problems solved by technology

The existing single-hole laparoscopic surgical sheath has the following deficiencies in the operation: 1. The instrument channel tube of the surgical sheath is outside the abdomen, and the support point for making the instrument swing is also outside the abdomen, and the narrowest part of the surgical sheath is located on the abdominal wall. The contradiction between the point located outside the abdomen and the narrow section located on the abdominal wall restricts the swing of the instruments, and the instruments are easy to cross and collide with each other, causing mutual interference and increasing the difficulty of operation; Curved laparoscopic instruments are expensive and easily damaged, which limits the development of single-port laparoscopy; 3. The structure of the surgical sheath is complex and difficult to place. These shortcomings are unfavorable factors affecting the development of single-port laparoscopy
