Abstract
The utility model discloses a protective sliding bush of scalpel blade, belonging to the medical appliance. The utility model comprises a longitudinal runner, a horizontal runner, a blade course, a front shrapnel, rear shrapnel and a push handle of the sliding bush. The longitudinal and the horizontal runner are engaged with the longitudinal and the horizontal axle of the secure scalpel handle so as to realize the sliding bush moving front and back along the scalpel handle; the tail end of the blade course is an upward tilt section which enables the raise of the blade tail and the break off of the handle; the free end of the front shrapnel and the rear shrapnel is provided with an inner convex body which can be inserted into the fixed hole of the blade at the central part, therefore, the blade is no breakable in the blade course of the sliding bush. When in use, the secure scalpel handle of the utility model can be arranged or removed when the blade is completely enclosed by the sliding bush, thereby, the cut or the infection caused by the contact of the operator and the blade is effectively avoided.
Description
Knife blade that technical field this utility model relates to protection sliding sleeve refers to a kind of especially and the safety scalpel handle is complementary, and can be with the blade jacket, be fixed in, loading, unloading have the blade protection sliding sleeve of protective effect in this safety scalpel handle together.
Scalpel that background technology is medical in the market and blade, great majority are not have safety guard, and blade is exposed, very easily hurts vast medical matters, and the cleanup crew makes them endure the threat that some fatal blood-borne pathogens infect to the fullest extent.We have invented a kind of scalpel with protection sliding sleeve in the early time; any model knife blade that its can and be used at present use that match; its protection sliding sleeve and blade then need be loaded onto this safety scalpel handle respectively, the blade application after mainly having prevented to reach in the operation, the incised wound in the processing.But its protection sliding sleeve can not wrap up blade this safety handle of a knife of fit on together, and the incised wound possibility of blade before avoiding performing the operation is so have to be solved.
Summary of the invention this utility model is to provide a kind of and can wraps up fully, is installed with blade; the blade of loading, unloading on the preceding safety scalpel handle of inventing protected sliding sleeve together; stop contacting of blade and operator's hands fully, farthest avoided the possibility of blade incised wound.
For reaching above-mentioned purpose, protection sliding sleeve of the present utility model has longitudinal and transverse chute, the blade layer, structures such as forward and backward shell fragment and sliding sleeve handle are formed, and are characterized in that vertical runner and the sideslip groove in the sliding sleeve crosses one another, open, the perforation of front and back ends, so that with longitudinal and transverse axle on safety scalpel handle fit mutually, the protection sliding sleeve can be slided front and back on handle of a knife, and the length that the regulated at will blade appears prevents incised wound; The veutro of sideslip groove is opened to the blade layer, and blade layer front end is open, and back-end closure has the inclined-plane of a ventralward updip in the bottom surface of rear end, when helping blade and desiring to unload handle of a knife, raises its afterbody; Free forward and backward two shell fragments in three limits are arranged on the outer surface of sliding sleeve veutro, and the interior convex body in the oriented inner projection of free-end of shell fragment can be entrenched in the fixing hole of blade fixed blade; The afterbody protuberance of veutro outer surface forms the sliding sleeve handle.
Design of the present utility model be continue before invented have protection sliding sleeve scalpel after; improvement invention to its protection sliding sleeve; blade can be installed with in the protection sliding sleeve; load onto the safety scalpel handle with the protection sliding sleeve; also can unload together and do not deviate from; having complete isolated operation person and contact with blade, at utmost prevent advantages such as incised wound or pollution sterilization back blade, is to meet medical safe standard theory and economical and practical product.
Description of drawings Fig. 1 is a schematic perspective view of the present utility model
Fig. 2 is the three-dimensional sectional structure sketch map of Fig. 1
Fig. 3 is a sectional structure sketch map of the present utility model
Fig. 4 is a label declaration in the facies ventralis structural representation accompanying drawing of the present utility model: 1. convex body 9. sliding sleeve handles in the convex body 7. back shell fragments 8. back shell fragments in the shell fragments before the shell fragments 6. before vertical runner 2. sideslip grooves 3. blade layers 4. top incline 5.
The specific embodiment sees also shown in Figure 1, formed by structures such as vertical runner 1, sideslip groove 2, blade layer 3, preceding shell fragment 5, back shell fragment 7, sliding sleeve handles 9 in the knife blade protection sliding sleeve of the present utility model, its characteristics are: please in conjunction with Fig. 2, shown in 3, vertical runner 1 and sideslip groove 2 in the sliding sleeve cross one another, and front and back ends is open, connect, can with the longitudinal axis on the safety scalpel handle, transverse axis fit mutually, make the whole protecting sliding sleeve before and after handle of a knife, slide the length that the regulated at will blade appears; The veutro of sideslip groove 2 is opened to blade layer 3, and blade layer 3 front end are open, and back-end closure has a ventralward top incline 4 in the bottom surface, rear end, helps blade when unloading handle of a knife, after raising its afterbody, is entrenched in the protection sliding sleeve and draws off handle of a knife together; See also shown in Figure 4; on the veutro outer surface of this blade protection sliding sleeve; shell fragment 5 before having two three limits free; back shell fragment 7; convex body 8 in convex body 6 and the back shell fragment in their preceding shell fragment of the oriented inner projection of free-end; they can embed in the fixing hole of blade central authorities, play the effect of fixed blade, and the sliding sleeve handle 9 of veutro outer surface afterbody can help user to promote whole sliding sleeve before and after handle of a knife.
Using blade protection sliding sleeve of the present utility model and all in the market blades is complementary; and by the fixing hole tabling of the interior convex body 8 on convex body 6 in the preceding shell fragment on its preceding shell fragment 5 and the back shell fragment 7 with blade central authorities; fixed blade does not drop out outside the sliding sleeve in the protection sliding sleeve.When longitudinal and transverse vertical runner 1 and sideslip groove 2 of handle of a knife along sliding sleeve, when inserting the protection sliding sleeve, convex body 6 in the shell fragment before the blade stiff end of handle of a knife at first touches, and shell fragment 5 is lifted, blade is become flexible, and insert in the holddown groove of handle of a knife top cutter; When convex body 8 was also loosened in the back shell fragment on the shell fragment of back, whole blade can unload the blade protective sleeve with handle of a knife; Promote sliding sleeve 9; the length of regulating the blade parcel or appearing; and when before final, pushing away whole blade protection sliding sleeve; when the blade tail end is lifted away from the handle of a knife stiff end with top incline 4; convex body 8 at first embeds the fixing hole of blade central authorities in the back shell fragment; when convex body 6 also embedded in the blade fixing hole in the current shell fragment, blade was installed with in the blade layer 3 of protection sliding sleeve fully, and with protecting sliding sleeve to push away handle of a knife and not coming off.This shows no matter blade still is after use before use, can be wrapped up by blade protection sliding sleeve fully, has farthest avoided contacting of operator and blade, has prevented the incised wound of blade effectively.
