Problems solved by technology

At the same time, in existing operations, it is usually necessary to cooperate with a laparoscope to collect images of the surgical part, so that the operator can perform corresponding surgical actions, but because the surgical instrument operator and the laparoscopic operator are performed by different personnel, and There is no guiding target inside the abdominal cavity, which causes the laparoscopic operator to lag behind in object capture, which cannot meet the needs of the operator, increases the working hours, and affects the efficiency of the operation

Embodiment 1

[0148] The flexible fixing part (wrist strap) of the wrist is connected and matched together with the C-shaped connector for support. The combination ensures a stable connection with the arm, and at the same time, the transmission of the C-shaped connector ensures the support and operability of the arm to the overall minimally invasive device;

[0149] The support connecting piece and the instrument mounting piece are connected through the dovetail groove guide rail to ensure the fit, guiding, stability and rapidity of the connection;

[0150] The instrument mounting part and the parts on the instrument shaft are fitted and connected through holes and shafts. Except for the parts on the instrument shaft, the rest are non-metallic parts. The low-friction holes and shafts between dissimilar materials ensure the rotation of the instrument shaft The flexibility of the device improves the accuracy of the operation. At the same time, the elastic one-way sheet structure at the end of...

Embodiment 2

[0174] The handle of the minimally invasive instrument handle is connected to the fixed handle through the first rotating shaft on the fixed handle; the handle is connected to the connecting rod of the handle through a pin shaft; the self-locking switch is connected through the second rotating shaft on the fixed handle; the self-locking switch spring Placed in the card slot on the fixed handle; the handle at one end of the pull rod is connected by a pin shaft, and the other end has a circular hole, and the steel wire hanging code (locking mechanism) is connected with the bearing through the circular hole on the pull rod to press and connect the pull rod return spring One end is placed on the steel wire hanging code, the other end is placed on the fixed handle, the opening and closing driving steel wire is fixedly connected to the steel wire hanging code; the rotating hand wheel is connected to the fixed hand wheel shaft. The above connection methods can be used to replace the c...

Abstract

The invention discloses a five-axis minimally invasive instrument integration system. The system comprises a surgical instrument, and a surgical unit, a deflection unit and a supporting unit which match the surgical instrument; the surgical instrument is configured to comprises a surgical head and an instrument rod; an universal adjusting assembly is arranged on the instrument rod; and at least one matching visual tracking point is arranged on the universal adjusting assembly. Compared with the prior art, the five-axis minimally invasive instrument integration system is used for solving the problems that in the prior art, a surgical head is fixedly connected with an instrument rod, and one instrument rod matches one surgical head, so that the cost of equipment is increased, and meanwhile the congenital defect that the existing surgical head cannot be replaced is overcome; and in addition, the matching visual tracking point is arranged at the adjusting assembly at the front end of the instrument, so that a camera in an endoscope can be guided to focus in real time, the position of the surgical head can be determined in real time, the surgical head is prevented from being in unnecessary contact with organs in an abdominal cavity, and the surgical risk is reduced.

Description

technical field [0001] The invention relates to the field of minimally invasive surgical instruments. More specifically, the present invention relates to a five-axis minimally invasive instrument integration system for use in minimally invasive surgical situations. Background technique [0002] Minimally invasive instruments refer to the tools used in minimally invasive surgery. Compared with traditional surgical operations, minimally invasive surgery has the advantages of less trauma, less pain, and faster recovery. However, due to the characteristics of minimally invasive surgery, doctors need to use special tools for minimally invasive surgery. Surgical tools are inserted into the patient's body through tiny incisions on the body surface for surgical operations. Therefore, the minimally invasive surgical tool usually has a long and thin rod, and the doctor needs to control the operating end at one end of the long rod to drive the execution end at the other end through th...
