Abstract
The invention relates to the technical field of medical equipment, in particular to a pair of medical forceps with a timely stable and accurate positioning function. The pair of medical forceps is formed by a positioning frame, a through hole, a left forceps arm, a right forceps arm, a bolt, a catch, a spring, a moving block, an expansion rod and a sliding chute. The top end of the left forceps arm and the top end of the right forceps arm are integrally combined. The positioning frame is an arc framework with a 340-degree circle center angle, and a plurality of teeth are arranged on the outer side wall of the positioning frame. One end of the positioning frame and the side wall of the left forceps arm are integrated, and the top point of the left forceps arm and the top point of the right forceps arm are located at the position of the circle center of the positioning frame. The other end of the positioning frame penetrates through the through hole located on the right forceps arm. The medical forceps can clamp absorbent cotton constantly without long-term force exerting through hands, and therefore finger fatigue caused in the process of the medical staff clamping the absorbent cotton for disinfecting is avoided. The medical forceps have the advantages of being energy-saving and convenient to operate.
Description
Technical field
The present invention relates to technical field of medical instruments, particularly relate to a kind of firm accurately medical forceps of positioning function in good time that have.
Background technology
Existing tweezers do not have self-locking mechanism usually, use tweezers to clamp in the process that absorbent cotton carries out disinfection medical personnel, and finger is in the state to the two arm application of forces of tweezers all the time, if overlong time is easy to generate fatigue.
Summary of the invention
The present invention provides a kind of firm accurately medical forceps of positioning function in good time that have of auto-lock function for solving the deficiencies in the prior art.
The scheme that solves the technology of the present invention problem is: have the firm accurately medical forceps of positioning function in good time, be made of locating rack, through hole, right tweezer arm, left tweezer arm, latch, catch, spring, movable block, expansion link and chute.Wherein, the top of the top of left tweezer arm and right tweezer arm is in conjunction with as a whole.Locating rack is that a central angle is 340 ° arc framework, and a plurality of teeth are arranged on the lateral wall of locating rack.One end of locating rack and the sidewall of left tweezer arm are as a whole, and the summit of left tweezer arm and right tweezer arm is positioned at the circle centre position of locating rack.The other end of locating rack passes the through hole that is positioned on the right tweezer arm.
Be provided with a chute in the lateral wall of right tweezer arm, movable block is in the described chute, movable block is combined as a whole with expansion link, expansion link is the cylindrical rod member that is parallel to right tweezer arm, the upper end of expansion link is the discoidal catch as a whole with expansion link, the upper surface of catch is and the latch of the as a whole wedge shape of catch that insert in the inter-lobe clearance of described locating rack the upper end of latch.Be with spring at expansion link, spring is between the end face of the bottom surface of catch and chute.
During use, only need mobile movable block that latch is extracted out from the inter-lobe clearance of locating rack, unclamp movable block after regulating the opening angle of two tweezer arms, latch inserts in the inter-lobe clearance of locating rack again under the promotion of spring, and tweezers need not external force and just can keep the clamping or the separated position that require this moment.
Adopt such scheme, can reach following effect:
Compared with prior art, the present invention need not to point the long-time application of force just can clamp absorbent cotton always, has avoided medical personnel to use tweezers to clamp that finger produces tired in the process that absorbent cotton carries out disinfection.Has laborsaving, easy to operate advantage.
