Abstract

The utility model discloses a condensed cutting self condensed knife, which comprises a knife blade, a knife nip, a knife rod and an outer tube as well as a knife handle; wherein the knife rod is sleeved inside of the outer tube, while the outer tube is provided with an outer tube handle to connect with the knife handle, and the knife blade is fixed at the front end of the knife rod through the matching of the knife nip and the knife blade positioning sheath; and the knife handle is provided with a spring inside to connect with the outer tube; wherein the outer tube can be contracted backward through the method of pulling the outer tube handle to compress the spring, thus the front knife nip exposing out to facilitate the knife blade replacement. The utility model is simple and convenient; the sharp knife blade is not only applied to common surgical, but also can cut the tissue and condense and stop the blood under the externally connected radio frequency current, thus suitable for the tissue condensed cutting of all parts of the human body and replacing the knife blade in the surgery process according to the convenient demand, so as to avoid intersection infection.

Description

Cut the self-solidifying cutter with fixed attention

Technical field

This utility model relates to technical field of medical instruments, more specifically relate to a kind of self-solidifying cutter of cutting with fixed attention, be applicable to common surgical procedures cutting, be particularly useful for joining and carry out cutting with fixed attention of partes corporis humani's bit organization, reach the function that when cutting and organizing, realizes coagulation with radio-frequency current.

Background technology

In clinical, the traditional approach of tissue cutting is to use common knife blade, and this sharp blade can fly-cutting, also can not produce toxic gas, but not have hemostatic function, need spend a large amount of energy toward contact and stop blooding.In recent years, treatment advantages such as high frequency electric knife is little with its damage, good effect and be widely used in clinical treatment, but because traditional electric knife can form the nonconducting thin film of one deck because of solidifying of patient's body fluid in cutting process, influence the performance of electric knife, often need be in operation process shaving or change electric knife repeatedly, prolonged operating time, make troubles for the operation doctor, also increased patient's misery, and traditional high frequency electric knife can produce a large amount of toxic gas in cutting process, the contaminated operation room environmental, and doctor and patient health damaged.Along with the development of medical skill, be badly in need of the hemostatic of a kind of sharpness, nonstaining property and high frequency electric knife that merges the general surgery blade in the novel operation cutter of one.

Summary of the invention

The purpose of this utility model is to provide a kind of self-solidifying cutter of cutting with fixed attention, it is simple in structure, easy to use, its sharp blade is not only applicable to common surgical procedures, and under the situation of external radio-frequency current, can when cutting and organizing, carry out coagulation, the tissue that is applicable to the partes corporis humani position is cut with fixed attention, and can carry out blade exchange according to needs easy to use in operation process, avoids the appearance of cross infection.

The technical scheme that its technical problem that solves this utility model adopts is: it is made of blade, knife bar, cutter holder, outer tube and handle of a knife.It is characterized in that: on knife bar, be provided with cutter holder and blade alignment pin, cutter holder by dowel fixes on knife bar, the knife bar encapsulation is in outer tube, outer tube diameter is complementary with the external diameter of knife bar (cooperating closely), the internal diameter of outer tube and the external diameter of knife bar only leave the space of slip, cooperation by locating hole on the cutter holder and blade alignment pin is fixed on the knife bar front end with blade, outer tube is connected with handle of a knife and is provided with outer tube shakes hands, establish spring in the handle of a knife, can adopt the mode of post-tensioning outer tube handle compression spring, contract after making the outer tube that is attached thereto, expose the mode of front end cutter holder and change blade easily.

The beneficial effects of the utility model are: can be by changing blade easily by cutter holder, avoided the cross infection of operation process, and can realize the therapeutic purposes of limit cutting edge coagulation when being connected with radio-frequency current, simple to operation, shortened treatment time of operation greatly, and do not produce toxic gas in the art, help the purification of operating room environment.

The specific embodiment

Below in conjunction with accompanying drawing this utility model is described in further detail:

According to Fig. 1 as can be known, blade 1 of the present utility model and knife bar 2 are on same horizontal line, cutter holder 3 is connected with knife bar 2 by pin 10, it comprises blade 1, knife bar 2, cutter holder 3, outer tube 4 and handle of a knife, on knife bar 2, be provided with cutter holder and blade alignment pin 5, cutter holder 3 is fixed on the knife bar 2 by pin 10, and can be the center rotation by pin 10, cutter holder 3 is provided with locating

hole

9, and 2 angles of cutter holder 3 and knife bar are 0 degree, and blade alignment pin 5 inserts in the locating hole 9, knife bar 2 is set in the outer tube 4, outer tube 4 is provided with outer tube handle 7 and is connected with handle of a knife 6, and spring 8 is housed in the handle of a knife 6, and the rear end of handle of a knife 6 can be used for radio-frequency current in succession.The facet of blade 1 can be slick or jagged.

During use, one holds handle of a knife 6, another hands pulls back outer tube handle 7, spring 8 in the handle of a knife 6 is compressed, outer tube 4 being contracted backward, expose the cutter holder 3 of front end, is that upwards turn at the center with cutter holder 3 with pin 10, the installing hole of blade 1 is placed on the blade alignment pin 5, with cutter holder 3 by on turn down, blade alignment pin 10 just in time penetrates in the locating hole 9 of cutter holder 3, after blade 1 installs, discharge outer tube handle 7, make outer tube 4 be returned to original position, at this moment, but this utility model is in state, can insert radio-frequency current in handle of a knife 6 rear ends and cut operation with fixed attention, also can be used as the cutting of common surgical procedures cutter and use.In the time will changing blade, operational approach is identical.
