Abstract
The invention discloses an improved structure of a laparoscopic surgery instrument handle and aims at leading hand feeling to be close to the natural state when a thumb and an index finger touch each other with strength by aid of the lever energy saving principle, reducing hand fatigue and shorting operation time. The improved structure comprises the instrument handle, wherein the instrument handle is composed of a fixed handle fixed on a handle seat and a moving handle hinged to the handle seat, a sliding rod is arranged between the lower end of the fixed handle and the moving handle, and the front end of the sliding rod is hinged to the fixed handle. A sliding chute penetrating the front end surface and the back end surface of the moving handle is arranged on the moving handle, the back end of the sliding rod extends into the moving handle from the front end surface of the moving handle, passes through the sliding chute and extends out from the back end surface of the moving handle, and a finger sleeve ring is arranged at the back end of the sliding rod. Compared with the prior art, the sliding rod extending in the direction of the moving handle is hinged at the lower end of the fixed handle, the back end of the sliding rod extends into the moving handle from the front end of the moving handle, passes through the sliding chute and extends out from the back end of the moving handle, the sliding rod can slide in the sliding chute when external force is applied to the moving handle, and therefore the force application intensity and operation fatigue of operators are reduced.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, particularly a kind of modified node method of laparoscopic surgery instrument handle.
Background technology
Over nearly 20 years, along with the progress of science and technology, laparoscopic surgery is subject to the extensive approval of doctor and patient, and the safety of laparoscopic surgery, effectiveness and invasive are familiar with gradually, and range of application is more and more wider.At present, although the most frequently used handle of operating theater instruments as various pliers, shears of peritoneoscope is easy to operate, but can not be laborsaving in use to greatest extent, and when applying active force, the feel of operating theater instruments is not good, operator easy hand fatigue or clamp in operation is caused incessantly, to affect operating time.
Summary of the invention
The object of this invention is to provide a kind of modified node method of laparoscopic surgery instrument handle, the technical problem solved is that feel when utilizing the principle of lever force-saving and hands thumb and forefinger firmly involutory is closer to naturalness, reduce hand fatigue degree, shorten operating time.
For solving the problem, the present invention realizes by the following technical solutions: a kind of modified node method of laparoscopic surgery instrument handle, comprise instrument handle, described instrument handle is made up of the fixed handle be fixed on handle base and the flexible handle be hinged on handle base, slide bar is provided with between the lower end of described fixed handle and flexible handle, front end and the fixed handle of slide bar are hinged, flexible handle is provided with the chute of through flexible handle front end face and rear end face, the rear end of slide bar is stretched into from the front end face of flexible handle, stretch out through the rear end face of chute by flexible handle, the rear end of described slide bar is provided with finger cot ring.
Be provided with connecting rod between the lower end of flexible handle of the present invention and slide bar, connecting rod connects flexible handle and slide bar respectively.
Front end and the slide bar of connecting rod of the present invention are hinged, the rear end of connecting rod and the lower end of flexible handle hinged.
The front end of connecting rod of the present invention is provided with Y-shaped union joint, Y-shaped union joint and slide bar hinged.
Y-shaped union joint of the present invention is arranged on the middle part of slide bar.
The length of connecting rod of the present invention is 1/2nd of slide bar length.
The present invention compared with prior art, a hinged slide bar extended along flexible handle direction in the lower end of fixed handle, the rear end of slide bar is stretched into from the front end of flexible handle and is stretched out by the rear end of flexible handle after chute, when applying external force to flexible handle, slide bar can slide in chute, reduces firmly size and the operation fatigue strength of operator.

Fig. 3 is the structural representation of connecting rod of the present invention.
Fig. 4 is using state reference diagram of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail.
As depicted in figs. 1 and 2, the present invention be directed to the operating theater instruments for laparoscopic surgery in prior art, the modified node method of laparoscopic surgery instrument handle comprises instrument handle 1, instrument handle 1 is by being fixed on the fixed handle 3 of handle base 2 lower front end and stretching in handle base 2 and the flexible handle 4 be hinged on handle base 2 forms, and flexible handle 4 is provided with handle movable axis 15 with the hinged place of handle base 2.
The spherical joint seat 12 be connected with pliers in prior art or shears pull bar is provided with in the upper end of flexible handle 4, flexible handle 4 is provided with the chute 6 of through flexible handle 4 front end face and rear end face, chute 6 is arranged along the length direction of flexible handle 4, be provided with a slider block 13 for being connected with slide bar 5 in the lower end of fixed handle 3, front end and the slider block 13 of slide bar 5 are hinged.The thickness of slide bar 5 is equal with the width of chute 6, slide bar 5 with the rotating shaft of slider block 13 hinged place are provided with slide bar movable axis 10, the rear end face of flexible handle 4 is stretched out in the rear end of slide bar 5 in chute 6, finger cot ring 7 is provided with in the rear end of slide bar 5, the thickness of finger cot ring 7 is greater than the width of chute 6, and slide bar 5 is limited in chute 6.
Be provided with connecting rod base 14 in the lower end of flexible handle 4, be provided with connecting rod 8 between connecting rod base 14 and slide bar 5, the front end of connecting rod 8 is hinged on the middle part of slide bar 5, rear end and connecting rod base 14 hinged.Connecting rod 8 with the rotating shaft of connecting rod base 14 hinged place are provided with connecting rod movable axis 11, and the length of connecting rod 8 is 1/2nd of slide bar 5 length.
As shown in Figure 3, the side that connecting rod 8 is connected with slide bar 5 is provided with Y-shaped union joint 9, and connecting rod 8 is engaged and hinged by joint movable axis 16 and slide bar 5 by Y-shaped union joint 9.
