Abstract
The invention discloses a cervix coagulating and cutting surgical knife, which is composed of a blade, a blade clamp, a knife bar, an outer tube and a knife handle; the knife bar is sheath in the outer tube, a pull handle of the outer tube is arranged on the outer tube to be connected with the knife handle, the blade is fixed at the front end of the knife bar by the match of the knife clamp and a blade positioning pin, and a spring is arranged in the knife handle; the invention can cause the backward retraction of the outer tube which is connected with the compression spring by adopting a mode of backward pulling of the compression spring of the pull handle of the outer tube, so as to expose the blade clamp at the front end and conveniently replace the blade. The invention has simple structure and simple operation, the sharp blade is not only suitable for the general surgical operations, but can also carry out the coagulation and hemostasis at the same time of cutting the tissues under the circumstance of externally being connected radiofrequency current; the invention is suitable for the tissue coagulation and cutting of various parts of the human body; furthermore, the blade can be replaced according to the needs of convenient usage during the operation process, thus avoiding the emergence of cross infection.
Description
Technical field
The present invention relates to technical field of medical instruments, more specifically relate to a kind of cervix coagulating operating knife, 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 object of the present invention is to provide a kind of cervix coagulating operating knife, 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 solution adopted for the present invention to solve the technical problems 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 invention has the beneficial effects as follows: 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.
Description of drawings

Fig. 2 is a kind of cervix coagulating operating knife cutter head partial enlarged drawing.
Wherein: 1-blade, 2-knife bar, 3-cutter holder, 4-outer tube, 5-blade alignment pin, 6-handle of a knife, 7-outer tube handle, 8-spring, 9-locating hole, 10-pin
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail:
According to Fig. 1 as can be known, blade 1 of the present invention 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 the outer tube 4 recessed original positions that arrive again, at this moment, but the present invention 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 common surgical procedures cutter and cut the evil use.In the time will changing blade, operational approach is identical.
