Technical Field

The invention relates to the technical field of medical equipment, in particular to a detachable guide seat on a surgical robot.

Background

With the widespread use of traditional laparoscopic techniques, modern surgery has entered a minimally invasive age, and minimally invasive surgery is undoubtedly a revolutionary advance over traditional surgery. It is understood as one of the surgical development directions in the 21 st century, which is the leading technology of electronic display systems combined with high-tech surgical instruments and traditional surgical operations. However, the laparoscopic device is generally larger in volume and more complex in structure, and particularly, a plurality of surgical mechanical arms closer to a human body, such as graspers for laparoscopic surgery, can be arranged on the surgical mechanical arms after being modified, and surgical instruments such as the graspers and the like are controlled by the surgical mechanical arms; because the length of the surgical instruments such as the nippers is longer, the tail ends of some existing surgical mechanical arms are provided with a guide seat which is inserted and sleeved on a nipper rod body and can mechanically support and guide the nippers; the existing guide seat is inconvenient to disassemble from the surgical mechanical arm, and the cleaning and the sterilization are also inconvenient after the disassembly.

In order to achieve the purpose, the technical scheme adopted by the invention is as follows:

a detachable guide seat on a surgical robot comprises a rectangular shell, wherein a sealing cover is formed at the upper end of the shell, an opening is formed at the lower end of the shell, a rectangular sealing plate is inserted into the lower end of the shell, annular sealing grooves are formed in the side walls of the periphery of the sealing plate, sealing rings are fixedly inserted into the sealing grooves, and the sealing rings are pressed on the inner side wall of the shell; vertical inserting plates are formed on two sides of the lower end face of the sealing plate, and rectangular clamping blocks are formed in the middle of the outer end face of each inserting plate; a horizontal limiting plate is inserted between the inserting plates, and two ends of the limiting plate are inserted on the shell; the limiting plate is screwed with a fastening bolt, and the tail end of the fastening bolt is pressed against the lower end face of the sealing plate; an upper clamping block is formed on the bottom surface of the inner side of the shell, a lower clamping block opposite to the upper clamping block is formed on the upper end surface of the sealing plate, a guide sleeve is clamped between the lower clamping block and the upper clamping block, and a plurality of annular sealing lips are fixedly inserted in the guide sleeve; through holes opposite to the inner holes of the guide sleeves are formed in the front end face and the rear end face of the shell.

Preferably, circular arc-shaped clamping grooves are formed in the upper clamping block on the shell or the lower clamping block on the sealing plate, the circular arc radius of each clamping groove is equal to the diameter of the outer wall of the guide sleeve, and the guide sleeve is inserted into the clamping grooves of the upper clamping block and the lower clamping block.

Preferably, the central axis of the through hole on the shell coincides with the central axis of the guide sleeve, and the aperture of the through hole is larger than that of the inner wall of the guide sleeve.

Preferably, conical chamfers are formed on the inner walls of the two ends of the guide sleeve.

Preferably, rectangular slots are formed in the front end face and the rear end face of the shell, two ends of the limiting plate are inserted into the slots of the shell, and the length of each slot is equal to the width of the limiting plate.

Preferably, a positioning counter bore is formed in the lower end face of the sealing plate, and the tail end of the fastening bolt is inserted into the positioning counter bore of the sealing plate.

Preferably, the insert plates on two sides of the buckling block are formed with vertical cutting grooves.

Preferably, a circular support ring is fixed on the inner wall of the guide sleeve, a conical elastic framework is formed on the support ring, a plurality of notches are formed on the elastic framework, and the sealing lip is coated on the elastic framework.

The invention has the beneficial effects that: the adopted guide seat is convenient to disassemble on the surgical mechanical arm, and meanwhile, sweat, blood and the like attached to surgical instruments such as a nipper and the like can be intercepted, so that the surgical mechanical arm is prevented from being polluted; meanwhile, the guide seat is convenient to disassemble and wash, clean and sterilize.
