Abstract

The invention discloses a flexible minimally invasive surgery instrument based on a natural orifice. The flexible minimally invasive surgery instrument comprises an operation handle, a wrist driving device, a connecting catheter, a flexible wrist part and a tail end executing device. The flexible minimally invasive surgery instrument can be integrally applied to minimally invasive surgery in the fields of abdominal cavity, thoracic cavity, urination, gynecology and the like. In the surgery implementation process, the minimally invasive surgery intelligent instrument passes through a trocar hole formed in the body surface of a patient, and a doctor holds the instrument by hand, and puts the instrument into the body to implement the surgery operation; the instrument is held by the doctor by hand; all operations, including the instrument tail end opening and closing movement, of an ordinary minimally invasive surgery instrument can be realized; meanwhile, the three-freedom-degree movement (the pitching movement, the swinging movement and the auto-rotation movement) of the tail end of the instrument can also be realized through controlling the operation handle and the wrist driving device. The space multi-freedom-degree surgery actions can be output by the instrument, the action is flexible, and the operation force is great; the instrument is more suitable for minimally invasive surgery with complicated actions.

Description

Technical field

[0001] The invention relates to a minimally invasive surgical medical equipment, in particular to a minimally invasive surgical instrument based on a natural cavity. Background technique

[0002] In the process of minimally invasive surgery, doctors use slender minimally invasive surgical instruments to perform surgical tasks. One end of the surgical instrument is held by the doctor, and the other end is inserted into the body through a tiny incision on the surface of the human body for surgical operations. Therefore, the surgical instrument is the only part that contacts the diseased tissue of the human body and is the only tool for directly performing surgical actions. In the implementation of surgery, because the movement of the end of the surgical instrument has a special mapping relationship with the movement of the handheld part of the instrument, in order to meet the action requirements of different surgical tasks (clamping, suture, knotting, etc.), doctors...

Embodiment Construction

[0026] The specific embodiments of the present invention will be described in detail below in conjunction with the drawings.

[0027] As attached figure 1 The shown present invention is a flexible minimally invasive surgical instrument based on a natural cavity, including: an operating handle 100, a wrist drive device 200, a flexible catheter 300, a flexible wrist 400, and an end effector 500, which can be applied to the abdominal cavity and thoracic cavity as a whole , Urology, gynecology and other fields of minimally invasive surgery. During the implementation of the operation, the minimally invasive surgical smart instrument passes through the card hole on the patient's body surface, and the doctor holds the instrument into the body to perform the surgical operation.

[0028] Contrast Figure 2a , Figure 2b , Figure 2c , Figure 2d The flexible minimally invasive surgical instrument based on the natural cavity is held by the doctor, which can realize all the operations of the ...
