Description

The micro- scissors of orthopaedics

Technical field

The utility model is related to field of surgical, and in particular to a kind of micro- scissors of novel orthopaedics.

Background technology

Currently, surgical operation enters micro- epoch, minimally invasive epoch, the thin such as hair of suture of operation, or even compare hair Also thin, and the material of suture is smooth, toughness is extremely strong, when using microscissors trimming after operation, due to the toughness of suture itself, It is easy to slide in and out, and needing scissors to open larger angle and suture is securely stuck in knife-edge part could complete to shear, however, The subtended angle of scissors is excessive, is easy to injure tissue, causes secondary injury, increases the pain of sufferer.

Invention content

The purpose of the utility model is to overcome micro- scissors of the existing technology can not effective and safe cutting toughness The drawbacks described above of extremely strong operation suture thread provides a kind of micro- scissors of novel orthopaedics, can prevent surgical thread from slipping, and It being capable of quick shearing operation suture thread.

The utility model is realized using technical solution below：

A kind of micro- scissors of orthopaedics, including two blades, two handles and two shrapnels, blade are connected to the one of handle End is equipped with axis hole, pivot is installed in axis hole between blade and handle；One end of shrapnel is connected to the other end of handle, shrapnel The other end is hinged, and the blade edge position of two blades protrudes outward to form cutting bed, and after blade occlusion, the knife edge arrives to cutting bed On；Two handles are equipped with position-limit mechanism, and the position-limit mechanism limits the opening amplitude of blade in a certain range；Connected The knife-edge positions that blade is arranged in position are equipped with crotch.

Above-mentioned technical proposal, further, the position-limit mechanism are limited block, are disposed therein on a handle, and The lower section of blade on another handle.

Above-mentioned technical proposal, further, the position-limit mechanism are inelastic soft line, and both ends are separately connected two hands Handle.

Above-mentioned technical proposal, further, the handle are equipped with non-slip texture.

Above-mentioned technical proposal is in further, between the blade and handle 60-80 ° of angle.

The micro- scissors of orthopaedics disclosed by the utility model, by the way that cutting bed is arranged in blade edge position, after blade occlusion, the knife edge Arrive to and form dissection on cutting bed, the cooperation of shear action between blade, can quick amputation suture, reach Preferably cut-out effect；The crotch of blade end can prevent operation suture thread from slipping；Position-limit mechanism is by the opening amplitude of scissors It limits in a certain range, prevents scissors subtended angle excessive, improve its security performance.

Specific implementation mode

In order to which the above objects, features, and advantages of the utility model are more clearly understood, below in conjunction with the accompanying drawings and Embodiment is described further the utility model.It should be noted that in the absence of conflict, embodiments herein and Feature in embodiment can be combined with each other.

Many details are elaborated in the following description in order to fully understand the utility model, still, this practicality Novel to implement using different from other modes described here, therefore, the utility model is not limited to be described below Specific embodiment.

Embodiment 1

Fig. 1 provides a kind of micro- scissors of orthopaedics, including two 1, two, blades for playing shear action for grip Handle 2 and two shrapnels 3.Blade 1, which is arranged between one end of handle 2, blade 1 and handle 2, is equipped with axis hole, and pivot is installed in axis hole Axis 21, one end of shrapnel 3 are connected to the other end of handle 2, and the other end of shrapnel 3 is hinged.

The blade edge position of two blades 1 protrudes outward to form cutting bed 11, and after blade 1 is engaged, the knife edge 12 arrives to cutting bed 11 On, as shown in Fig. 2, blade occlusion after the knife edge 12 and cutting bed 11 cooperation schematic diagram, in use, two panels blade 1 first to operation Suture is sheared, and is arrived on cutting bed 11 surgical thread with rear knife edge, is cut to operation suture thread.It carries significantly in this way Scissors, need not be opened larger angle, for the very high operation stitching of toughness by the high success rate for cutting operation suture thread Line also can be coped with easily.

Two handles 2 are equipped with position-limit mechanism 5, and the opening amplitude of blade is limited in a certain range, prevented by position-limit mechanism 5 Scissors subtended angle is excessive, improves its security performance.Position-limit mechanism 5 in the present embodiment is limited block, is disposed therein a handle On, and the lower section of the blade on another handle.

Fig. 3 is the enlarged drawing of blade end, and the knife-edge positions of blade 1 are equipped with crotch 13, can effectively prevent operation stitching Line slips.

In order to be pinched conducive to grabbing for finger, handle 2 is equipped with non-slip texture.

In order to adapt to the action in various spaces and position, it is more suitable for the operation in small space and corner, blade 1 and handle It is in 60-80 ° of angle between 2.

Embodiment 2

Fig. 4 provides a kind of orthopaedics fiber scissors, and difference from Example 1 is, position-limit mechanism 5 is inelastic soft Matter line, for example, high intensity nylon.It is oppositely arranged adjustment hole 6 on the inside of handle, the both ends of soft line are connected by adjustment hole 6 respectively Two handles 2.By adjusting position of the soft line on handle, the scope of activities of scissors subtended angle can be easily controlled.

In the present invention unless specifically defined or limited otherwise, the terms such as term " connection ", " connected " should all be done It broadly understood, for example, it may be fixedly connected, may be a detachable connection or integrally connected；It can make to be directly connected to, also may be used To be indirectly connected with by intermediary.For the ordinary skill in the art, can understand as the case may be above-mentioned The concrete meaning of term in the present invention.

Embodiment described above is only that preferred embodiments of the present invention are described, not new to this practicality The range of type is defined, and under the premise of not departing from the spirit of the design of the utility model, those of ordinary skill in the art are to this reality The various modifications made with novel technical solution and improvement should all fall into the protection model of the utility model claims book determination In enclosing.
