Problems solved by technology

However, this does not completely solve the above-mentioned technical defects, and manpower is still required to maintain the position of the instrument during the operation
Moreover, the guide wires that control the relaxation of the jaws and the bending of the jaws will also pass through the same minimally invasive aperture, which will inevitably reduce the aperture size of the instrument channel.
Moreover, these instruments are made of non-disposable materials, and the pores of the mechanical structure that controls the jaws are easy to retain patient's body fluids and tissues, so they need to be carefully cleaned and disinfected after the operation.

Embodiment Construction

[0019] like figure 1 , The hanger consists of a longitudinal main body 1 having a tail end 8 and a proximal end 7 . The longitudinal body extends proximally to caudally, and the thickness of the body is uniform until near the caudal end. In the region 2 near the tail end, the thickness of the material gradually becomes thinner. The tail end of the main body is connected with a tail end strip by the connecting part 3 . The end strip 5 consists of two parts, called the first part 4 and the second part 6 . The proximal end 7 of the main body is a curve with a fixed curvature, which is an area for the operator to hold. The material thickness of the main body 1 is uniform up to the area of ​​reduced thickness 2 and the connecting portion 3 near the tail. The thickness of the reduced thickness region and the connecting portion is less than the thickness of the main body, preferably half of the thickness of the main body. The connecting portion 3 continues to extend to form the ...

Abstract

The present invention relates to a tissue suspension device used during surgical intervention, comprising an elongated longitudinal body (1), the longitudinal body (1) comprising a proximal end (7) and a tail end (8), the longitudinal The body (2) extends from the proximal end to the tail end, and is characterized in that most of the longitudinal body (2) maintains the same thickness, and the thickness of the longitudinal body (2) becomes thinner near the tail end (8), and at The tail end of the longitudinal body (1) is connected to a tail end strip (5) via a connecting portion (3). The suspension device of the invention can be used at one time, has little damage to the human body, can effectively fix human tissues, and expose the surgical field of view.

Description

technical field [0001] The present invention relates to a surgical instrument, in particular to a tissue suspension device used in surgical intervention. Background technique [0002] During minimally invasive surgery, the surgical field of view is often affected by human tissues such as organs, muscles, and cartilage. The traditional method is to change the patient's posture (such as Trendelenburg position) by moving the patient to obtain a better surgical field of view. This method is inconvenient for doctors and may cause greater trauma to patients. [0003] Therefore, in order to obtain a better surgical field of view and increase the safety of the operation during the operation, many tissues and organs have been retracted, separated, and fixed instruments have been developed. Chinese patent document CN201120103023 provides a "three-leaf fan-shaped pliers", which includes a main body, which is in the shape of pliers. The head of the main body consists of two spreading...
