Abstract
The utility model discloses medical parallel spreader pincers, belonging to medical surgical instruments, which essentially comprise two pincers rods and two operation handles. The pincers rods are arranged in parallel; the medical parallel spreader pincers are characterized in that concave grooves are respectively arranged on the upper side faces of the pincers rods; a movable jaw is arranged in an open groove at the front end part of each pincers rod through a bolt, which for one thing is convenient for the pincers rod to extend into and for the other thing effectively increases the length of the pincers rod so as to effectively reach the surgical site. The medical parallel spreader pincers are accurate in positioning and not easy to skid and ensure the smooth progress of the surgery. The medical parallel spreader pincers are simple in structure, convenient to use and strong in practicability. The medical parallel spreader pincers are applicable for horizontal spreading in various surgeries, provide convenience for the surgery and reduce the difficulty of the surgery.
Description
Technical field
This utility model belongs to the medical surgical operating theater instruments, and particularly a kind of surgical operation is with the parallel pincers that strut.
Background technology
In the surgical procedures, often use the parallel pincers that strut, be used to strut tendon or skeleton, operation undergos surgery.The used parallel pincers that strut are made up of two claw beams and two operating grips now, and claw beam be arranged in parallel.This kind struts pincers and has following shortcoming: the 1st, when claw beam struts,, can not effectively locate for some operation, and cause slip phenomenon to take place, influence the exposure of operating field and the operation of operation.The 2nd, the claw beam design is too short, for some operation, can not reach effective site.The 3rd, when stretching into tendon or skeleton before strutting, because two claw beams be arranged in parallel, end and rear portion width are identical, are difficult for stretching into of claw beam.The problems referred to above cause the operation difficulty.
Summary of the invention
The purpose of this utility model is to provide a kind of medical parallel pincers that strut that strut firm position, is convenient to stretching into of claw beam.
This utility model is achieved in that
The medical parallel pincers that strut, mainly comprise two claw beams and two operating grips of linking to each other by rotating shaft, two claw beams be arranged in parallel, it is characterized in that: have the open type groove on the lateral surface of described claw beam leading section, be provided with an active jaw in the open type groove, this jaw is by being bolted on the claw beam; Also have corresponding Baltimore groove on the upper side of described claw beam.
After this utility model adopts said structure, need strut the Baltimore groove of position by external-open in the surgery and strut, accurate positioning is difficult for slippage, guarantees normally carrying out of operation.The moving jaw that the end is set up, the one, be convenient to stretching into of claw beam, the 2nd, the length that has effectively prolonged claw beam can reach effective operative site.Has simple in structure, easy to use, practical effect.The level that can be used for various operations struts, and makes things convenient for operation technique, reduces operating difficulty.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model, and Fig. 2 is the another kind of status architecture sketch map of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
In the accompanying drawing, 1 is that claw beam, 2 is that operating grip, 3 is that jaw, 4 is that Baltimore groove, 5 is bolt.
As shown in Figure 1, this utility model is a kind of improved medical parallel pincers that strut, and mainly is made up of two parallel claw beams 1 and two operating grips 2, and claw beam 1 and operating grip 2 link to each other by rotating shaft.Have rectangular open type groove on the lateral surface of claw beam 1 leading section, be provided with a jaw that can vertically move 3 in the open type groove, the front end of jaw 3 stretches out the open type groove, and is designed to pointed.Two jaw 3 corresponding settings, when moving in the jaw 3, the pointed end of two jaws 3 can be closed together, is convenient to stretch into to strut the position.Described jaw 3 is fixed in the open type groove of claw beam 1 by bolt 5, screws bolt 5, can adjust jaw 3.As shown in Figure 2, move in the jaw 3 and make closed end, form one and have the caliper that stretches into point; As shown in Figure 1, jaw 3 also can be arranged in parallel with claw beam 1, thereby prolongs claw beam 1, forms the caliper of a lengthening.On the upper side of each claw beam 1, have 4, two Baltimore grooves of a Baltimore groove, 4 corresponding settings respectively, be used for supporting to strut the position, prevent slippage near jaw 3 places.
Be the fastness of increase after strutting, the medial surface design of described Baltimore groove 4 has bar shaped or square check.
During use,, adjust jaw 3, make it most advanced and sophisticated closed or parallel with claw beam 1 according to difference operation needs, fixing with bolt 5, can carry out routine by operating grip 2 and strut operation.
Claims (3)
1, the medical parallel pincers that strut, mainly comprise two claw beams (1) and two operating grips (2) that link to each other by rotating shaft, two claw beams (1) be arranged in parallel, it is characterized in that: have the open type groove on the lateral surface of described claw beam (1) leading section, be provided with an active jaw (3) in the open type groove, this jaw (3) is fixed on the claw beam (1) by bolt (5); Also have corresponding Baltimore groove (4) on the upper side of described claw beam (1).
2, the medical parallel pincers that strut according to claim 1, it is characterized in that: the front end of described jaw (3) stretches out the open type groove and is designed to pointed.
