Abstract
The utility model provides a multifunctional surgical knife, comprising a knife handle, wherein the knife handle is connected with a blade. The multifunctional surgical knife is characterized in that a slide chute is arranged on the knife handle; a suction tube is connected to the slide chute; the blade of the suction tube can extend outside the remote end of the blade oppositely to the knife handle; a spring sheet is arranged on the suction tube; a protruding section is arranged on the spring sheet; and a groove for containing the protruding section of the spring sheet is arranged in the slide chute. According to the multifunctional surgical knife, by adding the movable suction tube to the surgical knife, the surgical knife provided by the utility model can be used as a common surgical knife, and can also be used as the suction tube to connect the multifunctional surgical knife used by a negative pressure aspirator in the operation process; and the multifunctional surgical knife has the advantages of being simple in structure, reasonable in design and dual-purpose.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically, relates to a kind of Multifunctional bistoury.
Background technology
Scalpel is a kind of medical apparatus and instruments necessary in surgical procedures.In operation process, the doctor need to use scalpel to cut pathological tissues, and this can cause local vascular to destroy, tissue fluid and blood ooze out, cause surgical field of view unclear, at this moment just need to attract, use the suction catheter that connects vacuum extractor that the liquid in surgical field of view is absorbed.These process need two doctor cooperations will the doctor be put down scalpel when only having a doctor or surgical field of view narrow and small, use suction catheter, and this has extended operating time virtually, has both increased patient painful, has increased again the risk of maloperation.Clinical needs are a kind of can carry out simultaneously scalpel and cut the scalpel that operation can be used as suction catheter again.
The utility model content
The purpose of this utility model is to overcome the weak point of above-mentioned conventional art, provides a kind of scalpel that can carry out simultaneously to cut the Multifunctional bistoury that operation can be used as suction catheter again.
The purpose of this utility model reaches by following technical measures:
A kind of Multifunctional bistoury, comprise handle of a knife, be connected with blade on handle of a knife, it is characterized in that: handle of a knife is provided with chute, be connected with suction catheter on chute, the blade end of suction catheter can extend out to far-end over blade with respect to handle of a knife, and suction catheter is provided with shell fragment, shell fragment is provided with protuberance, and chute is provided with the groove that holds the shell fragment protuberance.Chute is provided with to the midline outstanding buckle, and buckle can prevent that suction catheter from deviating from from chute.In use, first the shank end of suction catheter is connected vacuum extractor.When using as scalpel, suction catheter is return shank end, and the blade of scalpel is exposed; Surgical field of view blood or exudate are more when occurring in operation process, when needs attract, suction catheter is released to blade end, and suction catheter stretches out over blade, and the protuberance on the suction catheter shell fragment is inserted into the groove on chute simultaneously, suction catheter is fixed, and convenient attraction operates.
As a kind of improvement, be fixedly connected with the protective sleeve that can hold blade on suction catheter.Protective sleeve can hold blade when suction catheter is released, avoid occurring in the attraction process accident of blade mistake cutting.
As a kind of improvement, the length of suction catheter blade end is greater than the length of protective sleeve.The length of suction catheter blade end can guarantee the effect that attracts greater than the length of protective sleeve, prevent from that protective sleeve from hindering to attract operation.
As a kind of improvement, the blade end of suction catheter is provided with several side openings.Side opening can reduce the probability that attraction hole, suction catheter end is blocked.
As a kind of improvement, totally three of side openings.
Owing to having adopted technique scheme, compared with prior art, the utility model has the advantages that:
This utility model set up in scalpel can be movable suction catheter, make the scalpel in this utility model become a kind of can the use as coventional scalpel, can connect as suction catheter the Multifunctional bistoury that vacuum extractor uses in operation process again, have advantages of simple in structure, reasonable in design, dual-use material.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Accompanying drawing 1 is the structural representation of a kind of Multifunctional bistoury of this utility model;
Accompanying drawing 2 is the structural representations when in accompanying drawing 1, suction catheter is released.
The specific embodiment
Embodiment: as shown in Figures 1 and 2, a kind of Multifunctional bistoury, comprise handle of a knife 9, be connected with blade 1 on handle of a knife 9, handle of a knife 9 is provided with chute 4, is connected with suction catheter 10 on chute 4, the blade end of suction catheter 10 can extend out to far-end over blade 1 with respect to handle of a knife 9, suction catheter 10 is provided with shell fragment 8, and shell fragment 8 is provided with protuberance 7, and chute 4 is provided with the groove 2 that holds shell fragment 8 protuberances 7.Chute 4 is provided with to the midline outstanding buckle 6, and buckle 6 can prevent that suction catheter 10 from deviating from from chute 4.In use, first the shank end of suction catheter is connected vacuum extractor.When using as scalpel, suction catheter 10 is return shank end, and the blade 1 of scalpel is exposed; Surgical field of view blood or exudate are more when occurring in operation process, when needs attract, suction catheter 10 is released to blade end, and suction catheter 10 stretches out over blade 1, and the protuberance 7 on suction catheter 10 shell fragments 8 is inserted into the groove 2 on chute 4 simultaneously, suction catheter 10 is fixing, and convenient attraction operates.
Be fixedly connected with the protective sleeve 5 that can hold blade 1 on suction catheter 10.Protective sleeve 5 can hold blade 1 when suction catheter 10 is released, avoid occurring in the attraction process accident of blade 1 mistake cutting.
The length of suction catheter 10 blade end is greater than the length of protective sleeve 5.The length of suction catheter 10 blade end can guarantee the effect that attracts greater than the length of protective sleeve 5, prevent from that protective sleeve 5 from hindering to attract operation.
The blade end of suction catheter 10 is provided with several side openings 3.Side opening 3 can reduce the probability of suction catheter 10 attraction holes, ends obstructions.
In the present embodiment, side opening 3 is totally three.
