Abstract

The invention relates to medical operative instruments, in particular to an operative instrument convenient in cutting apart of contractural fascia, epimysia, perimysia or endomysia. The operative instrument comprises a knife handle, a knife body connected with the knife handle, a knife blade and a positioner, the knife blade and the positioner are connected with the knife body, the knife body is in the shape of an elliptic cylinder, the positioner is an elliptic-cylinder-shaped sleeve, and the knife body and the positioner can be in sleeved fit. When the operative instrument is in use, one end of the positioner is enabled to contact with a position where operation is needed, then the knife body is inserted into the positioner, and finally the handle is rapped by a handle.

Description

A kind of operating theater instruments of fascia, epimysium, perimysium or the endomysium of being convenient to cut contracture

technical field

?the present invention designs medical surgical instrument, is specifically related to a kind of operating theater instruments of fascia, epimysium, perimysium or the endomysium of being convenient to cut contracture.

background technology

In medical practice, often need to cut fascia, epimysium, perimysium or the endomysium of patient's contracture, can remove spasm to make affected part, remove patient's slight illness, the operating theater instruments of fascia, epimysium, perimysium or the endomysium of existing incision patient contracture has the defect of three aspects:: 1, blade is flat mouth, the knife edge is straight line, and such operating theater instruments is because resistance is large, and operation can allow comparatively pain of patient; 2, because some doctors can not find the position of operation and feed, sword direction exactly accurately, often need repeatedly to descend cutter, sword, the pain while having increased especially patient's feed; 3, doctor normally implements operation with hand-held handle of a knife, especially abecedarian, and inserting needle speed is fast not, the pain while greatly having increased patient's feed.

summary of the invention

For solving the problems of the technologies described above, the present invention proposes a kind of operating theater instruments of fascia, epimysium, perimysium or the endomysium of being convenient to cut contracture, in the time entering cutter, sword, can reduce the number of times into cutter, sword, thereby can greatly reduce patient's pain.Its technical scheme is:

A kind of operating theater instruments of fascia, epimysium, perimysium or the endomysium of being convenient to cut contracture, the blade that comprises handle of a knife, be connected with handle of a knife, blade and the localizer being connected with blade, described handle of a knife is elliptical cylinder-shape, described localizer is elliptical cylinder-shape sleeve, and described handle of a knife and described localizer can fits.In the time using this operating theater instruments, first an end in contact of localizer is implemented to the position of operation at needs, then blade is inserted in localizer, finally use hands knocking handle of a knife.

Further, described blade has the knife edge, and the described knife edge is elliptic arc structure, and the knife edge is parallel with the major diameter of the ellipsoid of localizer, and in same plane.In the time using this operating theater instruments, first by an end in contact skin of localizer, the major diameter of oval-shaped localizer is parallel or angled with the fiber orientation of fascia, epimysium, perimysium or endomysium, then blade is inserted in localizer, finally use hands knocking handle of a knife.Such design, can ensure that the knife edge cuts fascia, epimysium, perimysium or endomysium.

Further, the knife edge part of described blade is decussate texture.Such structure, owing to having two knifes edge, if doctor does not find operative site exactly, but it is not too large to depart from accurate position distance, and in two knifes edge also has the probability that cuts to fascia, epimysium, perimysium or endomysium so.

Further, the sword face of described blade is made up of two gradient Different Plane, and the close plane of the knife edge and the angle of blade cross section are greater than the angle of another plane and blade cross section.Such design, can ensure under the prerequisite of blade and blade rigidity, will reduce near the angle between the blade face of the knife edge as far as possible, so that rapid feed, and the pain when reducing feed.

Further, on the bus at two end points places of the major diameter of described handle of a knife cross section, be provided with symmetrically projection, the quantity of described projection is more than 2 pairs.Such design, can reduce the friction between handle of a knife and localizer, is convenient to feed, accelerates feed velocity, the pain when reducing feed.

Further, on the bus at two end points places of the minor axis of described handle of a knife cross section, be provided with symmetrically projection, the quantity 2 of described projection to more than.Such design, can reduce the friction between handle of a knife and localizer, is convenient to feed, accelerates feed velocity, the pain when reducing feed.

Detailed description of the invention

Embodiment 1

A kind of operating theater instruments of fascia, epimysium, perimysium or the endomysium of being convenient to cut contracture, blade 2 and localizer 4 that the blade 1 that comprises handle of a knife 3, be connected with described handle of a knife 3 is connected with described blade 1, described handle of a knife 3 is elliptical cylinder-shape, described localizer 4 is elliptical cylinder-shape sleeve, and described handle of a knife 3 can fit with described localizer 4.Described blade 2 has the knife edge, and the described knife edge is elliptic arc structure, and the knife edge is parallel with the major diameter of the ellipsoid of localizer 4, and in same plane.The sword face of described blade is made up of two gradient Different Plane, and the close plane of the knife edge and the angle of blade 1 cross section are greater than the angle of another plane and blade cross section.On the bus at two end points places of the major diameter of described handle of a knife 3 cross sections, be provided with symmetrically projection, the quantity 2 of described projection to more than.Described handle of a knife 3 is medical plastic material, and described blade 1 and the knife edge are steel.The major diameter of oval blade 1 is 0.3-0.8 millimeter, the minor axis of oval blade 1 is 0.3-0.5 millimeter, large 0.05 millimeter of the major diameter of the oval handle of a knife 1 of draw ratio of localizer 4, large 0.05 millimeter than the minor axis of oval handle of a knife 1 of the minor axis of localizer 4, projection 5 is 0.03 millimeter with the gap of localizer inwall.Such design, make handle of a knife can with localizer fit, but can in localizer, not rock.
