Description
Technical field
The present invention relates to the field of medical instrument technology, are used for laparoscopic surgery robotic tool in particular to one kind
Bindiny mechanism.
Background technique
Minimally Invasive Surgery is that one kind mainly makes surgeon without making to patient through endoscope and various imaging techniques
It performs a surgical operation in the case where at huge wound.The Minimally Invasive Surgery of early stage refers exclusively to laparoscopic surgery, because there was only abdominal at that time
It can be replaced Minimally Invasive Surgery.Due to the wound very little of Minimally Invasive Surgery, and recovery period is short, therefore has been favored by people,
Present minimally invasive surgery technology is universal to be widely used in various operations.
It opens up several apertures when Minimally Invasive Surgery on the stomach wall of sufferer first, is then placed in the surgical instruments such as scissors, pliers,
The sequence of operations such as clamp, cutting, suture, knotting are carried out to the tissue of lesion.However the freedom degree of existing surgical instrument is limited,
Usually do not have pitching and beat freedom degree, more clumsy, automaticity is poor, has seriously affected the quality and precision of operation.Therefore,
It is improved aiming at the problems existing in the prior art.
In order to solve the above technical problems, application No. is the utility models of CN201420805476.8 to disclose one kind for micro-
The multiple degrees of freedom surgical instrument of invasive procedures, including portion of the handle, the power drive portion being fixedly connected with the portion of the handle, with
Thin connecting rod that the power drive portion is fixedly connected, the end execution part being connect with the thin connecting rod, the control power
The control system of drive part movement, wherein the portion of the handle and power drive portion pass through route and control system
System is connected, and the movement of the portion of the handle will drive the movement of joint encoder, and encoder acquires the movement letter of corresponding joint
Breath, is then fed back to the control system, and the power drive portion drives institute after receiving the signal of the control system
It states end execution part and completes pitching, beat and holding action.Above-mentioned utility model turns with pitching, beat, clamping and axis
Four freedom degrees, automaticity with higher can effectively improve surgical quality and efficiency, and compact structure is compact.
The above-mentioned multiple degrees of freedom surgical instrument for Minimally Invasive Surgery may be implemented minimally invasive laparoscopic surgery commonly separate,
The elemental motions such as cutting, hemostasis, suture, can be realized the abdominal cavities such as gallbladder removal, nephrectomy typical procedure.
In laparoscopic surgery, need in laparoscopic surgery robotic tool (i.e. above-mentioned multiple degrees of freedom surgical instrument) and device
A suitable bindiny mechanism is found between tool pedestal, feature that there are four this bindiny mechanism's needs while tool：First, connect machine
Structure can transmit torque；Second, bindiny mechanism can do flexible move up and down；Third, it is contemplated that need to be with disposably when performing an operation
Every bacterium plate, bindiny mechanism can be easy to disassemble；4th, it is contemplated that the problem of space and weight, bindiny mechanism should be light reliable.
However, medical personnel is installing laparoscopic surgery robotic tool to appliance feet by bindiny mechanism
When, laparoscopic surgery robotic tool can generate certain impact to bindiny mechanism and appliance feet, and such impact can damage abdomen
Endoscope-assistant surgery robotic tool and appliance feet.
Summary of the invention
Technical problem solved by the invention：When laparoscopic surgery, laparoscopic surgery robotic tool is installed to instrument bottom
Impact caused by seat damages laparoscopic surgery robotic tool and appliance feet.
In order to solve the above technical problems, the present invention provides the following technical solutions：
A kind of bindiny mechanism for laparoscopic surgery robotic tool, including motor, the elasticity coupled with machine shaft
Body, connect with elastomer every bacterium plate, the wheel shaft being connect with every bacterium plate；The motor is mounted on appliance feet, the wheel shaft
It is mounted in laparoscopic surgery robotic tool；
The elastomer includes lower cover, one group of hinge assembly, upper cover, adjustable spring；It is each in one group of hinge assembly
The bottom end of hinge assembly is hinged on lower lid, and the top of each hinge assembly is hinged on lid in one group of hinge assembly,

Lid is fixedly connected with machine shaft, and the upper cover is connect with every bacterium plate.
According to the above technical scheme, it is as follows to install the workflow to appliance feet for laparoscopic surgery robotic tool：
First, motor is mounted on appliance feet, and elastomer couples with motor, and specifically, the shaft of lower cover and motor is solid
Fixed connection.
Second, it is mounted on elastomer every bacterium plate, specifically, every on the upper lid that bacterium plate is mounted on elastomer.
Third, wheel shaft are mounted on every on bacterium plate, laparoscopic surgery robotic tool and wheel axis connection.
Through the above technical solutions, when laparoscopic surgery robotic tool and wheel shaft connected to it are installed to every on bacterium plate
When, laparoscopic surgery robotic tool can bindiny mechanism to appliance feet and thereon generate certain impact, it is of the present invention
Elastomer in the cooperation of adjustable spring and one group of hinge assembly above-mentioned impact can be buffered, in order to avoid above-mentioned impact is to abdomen
Endoscope-assistant surgery robotic tool and appliance feet generate damage.Wherein, one group of hinge assembly, which is removed, cooperates with adjustable spring to buffer
Outside above-mentioned impact, can also make laparoscopic surgery robotic tool at work and can do it is flexible move up and down, moreover, one group is hinged
The torque that the setting of component can be such that motor exports is accurate and laparoscopic surgery robot device is steadily conveyed to through bindiny mechanism
Tool.
As the present invention to a kind of explanation of elastomer, in elastomer, each hinge assembly in one group of hinge assembly
It include the of upper hinge, lower hinge, the short pin shaft of hinged upper hinge and lower hinge, hinged upper hinge and upper cover
Second long pin shaft of one long pin shaft, hinged lower hinge and lower cover.
As the present invention to a kind of explanation of elastomer, in elastomer, the upper cover is equipped with multiple upper hinged seats, under described
Multiple lower hinged seats are covered with, the quantity that the quantity of the upper hinged seat is equal to lower hinged seat is equal to hinged in one group of hinge assembly
The quantity of component；The hinged upper hinge of first long pin shaft and upper hinged seat, the hinged lower hinge of the second long pin shaft and
Lower hinged seat.
As the present invention to a kind of explanation of elastomer, in elastomer, the upper cover and lower cover are disk-shaped, in upper cover
