Problems solved by technology

[0003] At present, the fixtures of the instruments used in the existing minimally invasive surgical robots only fix the instruments on the operating table, but cannot simulate the integrated movement of the human arm, wrist and fingers. Therefore, when performing more complex minimally invasive surgery , unable to meet the doctor's requirements for the degree of freedom, flexibility and sensitivity of surgical instruments

Embodiment Construction

[0073] The present invention will be further described below in conjunction with accompanying drawing.

[0074] Such as figure 1 and 2 As shown, the present invention provides an instrument fixing device for a laparoscopic surgical robot, which includes a drive base 1 , an isolation base 2 disposed on the drive base 1 , and a transmission base 3 disposed on the isolation base 2 . Wherein, the driving seat 3 is provided with an instrument connecting mechanism 4 , and the driving seat 1 is fixed with a driving mechanism 5 . In addition, the driving seat 1 also supports the instrument connecting mechanism 4 .

[0075] The connection manner among the driving seat 1 , the isolation seat 2 and the transmission seat 3 will be described in detail below.

[0076] The transmission seat 3 and the isolation seat 2 are quickly connected through the first quick release structure 6 .

[0077] Such as image 3 As shown, the first quick-release structure 6 includes a first positioning port...

Abstract

The invention relates to an instrument transmission seat for a minimally invasive surgical instrument. The instrument transmission seat comprises: a transmission seat main body; a first coupler arranged on the transmission seat main body and connected with the output shaft of a first motor; a second coupler arranged on the transmission seat main body and connected with the output shaft of a secondmotor; a third coupler arranged on the transmission seat main body and connected with the output shaft of a third motor; a rotating shaft penetrating through the side wall of the transmission seat main body, connected with the first coupler, and connected with an instrument through an instrument rod; a first seat connected with the transmission seat main body in a sliding mode, wherein the firstseat is connected with the second coupler through a first lead screw so as to make the first seat slide on the transmission seat main body, the first seat is connected with one end of a push rod sleeved with the instrument rod, and the other end of the push rod is hinged to the instrument; and a second seat connected with the transmission seat main body in a sliding mode, wherein the second seat is connected with the third coupler through a second lead screw so as to make the second seat slide on the transmission seat main body, the second seat is connected with one end of a traction rod arranged in the push rod, and the other end of the traction rod is used for making the traction rod reciprocate to enable the instrument to be opened and closed.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an instrument transmission seat for minimally invasive surgical instruments. Background technique [0002] On the basis of traditional surgery, minimally invasive surgery has been practiced and developed rapidly with many advantages such as fast postoperative recovery and small trauma. As a representative of minimally invasive laparoscopic minimally invasive surgery, it has become a major change in traditional open surgery. With the expansion of the field of minimally invasive surgery, the minimally invasive surgical robot system provides a new way to further improve minimally invasive surgery for the limitations of conventional endoscopic techniques in clinical applications. [0003] At present, the fixtures of the instruments used in the existing minimally invasive surgical robots only fix the instruments on the operating table, but cannot simulate the integrated m...
